[0022] The present invention relates to an automated mild steel pipe repairing device capable of repairing mild steel pipe in an automated manner. In addition, the proposed device is able to determine presence of any crack over the pipe and accordingly welding detected cracks for repairing the crack, thereby minimizing the labor cost with less time consumption.

[0023] Referring to Figure 1, an isometric view of an automated mild steel pipe repairing device is illustrated, comprising a platform 101 positioned over a ground surface and in proximity to a mild steel (MS) pipe by means of plurality of motorized omnidirectional wheels 102 arranged beneath the platform 101, a touch interactive display panel 103 installed over the platform 101, an artificial intelligence based imaging unit 104 installed over the platform 101, a pneumatic scissor lift arrangement 105 installed over the platform 101, a cuboidal body 106 configured with the arrangement and position in parallel to the pipe, a pair of L-shaped hydraulic bars 107 installed over lateral sides of the body 106, a T-shaped rod 108 configured with the body 106 by means of a robotic link 109, a motorized sliding unit 110 installed over inner periphery of the rod 108, a welding unit 111 configured with the sliding unit 110, a motorized grinding wheel 112 provided over the body 106 by means of a robotic arm 113.

[0024] The proposed device includes a platform 101 positioned over a ground surface and in proximity to a mild steel (MS) pipe by means of plurality of motorized omnidirectional wheels 102 arranged beneath the platform 101. The platform 101 as disclosed in the present invention is made up of any material selected from but not limited to metallic material alike utilize to position over a fixed surface. Upon activation of the proposed device by the user, primarily an inbuilt microcontroller actuates a touch interactive display panel 103 is installed over the platform 101 to enable a user to provide input regarding repairing of the pipe. The touch interactive display panel 103 as mentioned herein is typically an LCD (Liquid Crystal Display) screen that presents output in a visible form. The screen is equipped with touch-sensitive technology, allowing the user to interact directly with the display using their fingers. A touch controller IC (Integrated Circuit) is responsible for processing the analog signals generated when the user inputs details regarding repairing of the pipe.

[0025] Based on processing the input command, the microcontroller actuates an omnidirectional wheels 102 ranging from 4 to 6 in numbers. Each of the wheels 102 are coupled with a DC (Direct Current) motor that is activated by the microcontroller to provide circular motion to the wheels 102. The working principle of a DC motor is based on the interaction between a magnetic field and an electric current. When an electric current flows through the coil of wire, also known as the armature, it creates a magnetic field. This magnetic field interacts with the fixed magnets, known as the stator, causing the armature to rotate. The rotation is achieved by reversing the direction of the current flow in the armature coil using a commutator and brushes that provide continuous movement of the motor results in providing circular motion to the wheels 102 to facilitate translation to the platform 101 over the user desired surface.

[0026] Upon reaching to the user desired surface, the inbuilt microcontroller actuates an artificial intelligence-based imaging unit 104 as mentioned above is equipped having a processor that encrypted with AI (Artificial Intelligent) protocols to processes and analyses the images captured by the camera enabling it to perform various tasks beyond traditional image capturing. The AI analysis is performed locally on the camera itself and the real-time processing on the camera enables immediate responses and faster decision-making.

[0027] The camera, herein captures images of the pipe with the help of specialized lenses designed to capture high-quality visuals. The captured data is now pre-processed via the processor to enhance its quality and prepare it for AI analysis. This pre-processing involves tasks such as noise reduction, image stabilization, or color correction. The processed data is fed into AI protocols for analysis which utilizes machine learning techniques, such as deep learning neural networks, to extract meaningful information present in the images. Based on extraction of the data from the captured images, the microcontroller determines height of the pipe.

[0028] Post determining height of the pipe, the microcontroller actuates a pneumatic scissor lift arrangement 105 installed over the platform 101 to extend in accordance with the detected height and lift a cuboidal body 106 configured with the arrangement and position in parallel to the pipe. The pneumatic scissor arrangement comprises of linked bars 107 linked in a scissor like arrangement that powered by a pneumatic unit comprises of an air compressor, air cylinder, air valves and piston. The air valve that allows entry or exit of the compressed air from the compressor. Furthermore, the valve opens and the compressed air enters inside the cylinder thereby increasing the air pressure of the cylinder. The piston is connected to the cylinder and due to the increase in the air pressure, the piston extends due to which causing the arrangement either in accordance with the detected height and lift a cuboidal body 106 and position in parallel to the pipe.

[0029] Upon positioning body 106 in parallel to the pipe, the microcontroller actuates a laser measurement sensor installed over the platform 101 and synced with the imaging unit 104 to monitor dimensions of the pipe. The laser measurement sensor sends laser beams at two points of the pipe to form a triangle between the pipe and the point of the sensor from where lasers are emitted. The beams are bounced back towards the sensor and are sensed by the sensor with the angle formed between the emitting point and the pipe at which laser beam are impact. The laser measurement sensor, after detecting the required data of dimension of the pipe sends the data to the microcontroller. The microcontroller, upon receiving the signal, compares the received signal with the pre-fed data stored in the microcontroller database and based on the compared data, the microcontroller monitor dimensions of the pipe.

[0030] Synchronously, a proximity sensor installed with the body 106 and synced with the imaging unit 104 monitors distance of the pipe from the body 106. The proximity sensor used herein is preferably an ultrasonic proximity sensor that uses ultrasonic waves to monitor distance of the pipe from the body 106. The ultrasonic proximity sensor typically emits ultrasonic waves towards the pipe, the ultrasonic waves hit the pipe and bounce back to the sensor's receiver. The receiver of the ultrasonic proximity sensor is sensitive to the emitted ultrasonic waves and listens for the reflected waves. When the emitted ultrasonic waves are received by the receiver the proximity sensor sends the data to the microcontroller which processes. The microcontroller upon receiving the signal compares the received signal with the pre-fed data stored in the microcontroller database and based on the compared data, the microcontroller monitor distance of the pipe from the body 106 and accordingly the microcontroller regulates extension and retraction of the bars.

[0031] Based on detected dimensions and distance of the pipe the microcontroller actuates a pair of L-shaped hydraulic bars 107 installed over lateral sides of the body 106 to extend and grip the pipe in accordance with the detected dimensions by means of an extendable gripper installed with each of the bar. The pair of L-shaped hydraulic bars 107 powered by a hydraulic unit consisting of a hydraulic cylinder, hydraulic compressor, hydraulic valve and piston that work in collaboration for providing the required extension/retraction to the extendable gripper. The microcontroller actuates the valve to allow passage of hydraulic fluid from the compressor within the cylinder, the hydraulic fluid further develops pressure against the piston and results in pushing and extending the piston. The piston is connected with the extendable gripper and due to applied pressure the extendable gripper extends and similarly, the microcontroller retracts the extendable gripper by closing the valve resulting in retraction of the piston. The microcontroller regulates the extension/retraction of the extendable gripper for grip the pipe in accordance with the detected dimensions.

[0032] Consequently, a T-shaped rod 108 configured with the body 106 by means of a robotic link 109 is actuated by the microcontroller to position the rod 108 over the pipe. Herein, a crack detection sensor is installed over the rod 108 to determine presence of any crack over the pipe. The crack detection sensor as used herein is consists of a laser emitter and a receiver. The emitter emits a focused beam of laser light onto the pipe surface. If there is a crack present, the laser beam encounters an interruption or deflection, which is then detected by the receiver.

[0033] This disruption in the laser beam's path indicates the presence of a crack. The sensor then relays this information to the microcontroller. The microcontroller upon receiving the signal compares the received signal with the pre-fed data stored in the microcontroller database and based on the compared data, the microcontroller determines presence of any crack over the pipe. Based on which the microcontroller actuates the link 109 to position the rod 108 over the detected crack.

[0034] The robotic link 109 as mentioned above comprises of a shoulder, elbow and wrist. All these parts are configured with the microcontroller. The elbow is at the middle section of the link 109 that allows the upper part of the link 109 to move the lower section independently. Lastly, the wrist is at the tip of the upper link 109 and attached to the end effector works as hand for positioning the rod 108 over the detected crack.

[0035] Moreover, motorized sliding unit 110 installed over inner periphery of the rod 108 that is actuated by the microcontroller to provide translation to a welding unit 111 configured with the sliding unit 110. The motorized sliding unit 110 as mentioned herein consists of a rail unit that provides a guided path for linear movement. The rail unit usually includes a pair of parallel rails or tracks, along which the slider moves. The slider carriage, also called a stage or platform 101 equipped with a mechanism to minimize friction and ensure smooth motion. This involves the use of ball bearings. The slider incorporates a motor and a drive mechanism to generate linear motion. The motor is connected to a drive mechanism, such as a belt, lead screw, or ball screw. The drive mechanism converts the rotational motion of the motor into linear motion, propelling the slider carriage along the rail unit to translate a welding unit 111 configured with the sliding unit 110 over detected crack.

[0036] Upon positioning of the welding unit 111, the microcontroller actuates a capacitive position sensor is installed over said rod 108 to positioning and proximity of said welding unit 111 from said pipe. The capacitive position sensor as disclosed herein is functions by detecting changes in capacitance between the sensor and the pipe, in this case, the pipe. As the welding unit 111 moves along the surface of the pipe, the capacitive position sensor continuously measures the capacitance. When the distance between the capacitive position sensor and the pipe changes, the capacitance also changes due to the electrical properties of the pipe materials involved. This change in capacitance is then converted into a measurable signal and transmitted towards the microcontroller. The microcontroller upon receiving the signal compares the received signal with the pre-fed data stored in the microcontroller database and based on the compared data, the microcontroller positioning and proximity of said welding unit 111 from said pipe and actuates said arm to regulate positioning of said rod 108 over said pipe for enabling said welding unit 111 to appropriately weld sad crack.

[0037] Further, an ultrasonic sensor is installed over the body 106 to monitor thickness of the pipe. The ultrasonic sensor consists of a transducer and a receiver, herein the transducer emits ultrasonic waves towards the pipe, upon hitting the pipe body 106, and the waves are reflected back. The reflected waves are received by the receiver of the sensor. The received waves are converted into an analog value which is further converted into an electrical signal and is sent to the microcontroller. The microcontroller upon receiving the signal compares the received signal with the pre-fed data stored in the microcontroller database and based on the compared data, the microcontroller monitor thickness of the pipe based on which the microcontroller regulates operation of the welding unit 111.

[0038] The welding unit 111 performs welding of the detected cracks for repairing the crack. The welding unit 111 used herein is a Tungsten Inert Gas (TIG) welding which uses the generated heat by an electric arc struck between a non-consumable tungsten electrode and the hose pipe metal to repair detected crack. The welding unit 111 pats in a circle around the edge of the crack to start building it up, trying to lead it so that it filling the inside edge. Thus, welding of the detected cracks for repairing the crack in successful manner.

[0039] Post welding detected crack, the microcontroller actuates a robotic arm 113 that to position a motorized grinding wheel 112 provided over the body 106 over the welded crack. The robotic arm 113 as disclosed herein is comprises of a shoulder, elbow and wrist. All these parts are configured with the microcontroller. The elbow is at the middle section of the arm that allows the upper part of the arm to move the lower section independently. Lastly, the wrist is at the tip of the upper arm and attached to the end effector works as hand positions the wheel over the welded crack.

[0040] Upon positioning of the wheel, the microcontroller actuates the wheel to perform smoothening over the welded cracks. The motorized grinding wheel 112 is coupled with a DC (Direct Current) motor that is activated by the microcontroller to provide circular motion to the wheel. The working principle of a DC motor is based on the interaction between a magnetic field and an electric current. When an electric current flows through the coil of wire, also known as the armature, it creates a magnetic field. This magnetic field interacts with the fixed magnets, known as the stator, causing the armature to rotate. The rotation is achieved by reversing the direction of the current flow in the armature coil using a commutator and brushes that provide continuous movement of the motor results in providing circular motion to the grinding wheel 112 to perform smoothening over the welded cracks, thereby appropriately repairing the pipe.

[0041] Moreover, a facial detection module integrated with said microcontroller to determine people in proximity. The facial detection module as mentioned above recognizes facial features of individual such as eyes, nose and mouth. Once the faces are identified, the module calculates the coordinates of these key landmarks on face. And subsequently, measures the distance between corresponding facial landmarks across different faces, such as distance between nose and eye or the distance between noses to the chin. Further, the geometrical data regarding facial features of an individual transmitted towards the microcontroller for processing. The microcontroller upon receiving the signal compares the received signal with the pre-fed data stored in the microcontroller database and based on the compared data, the microcontroller determines people in proximity of the proposed device.

[0042] And in case any unauthorized person is detected, said microcontroller actuates a speaker installed over said body to inform said people regarding said unauthorized person. The speaker as used herein is works by receiving signals from the microcontroller, converting them into sound waves through a diaphragm's vibration, and producing audible sounds with the help of amplification and control circuitry in order to inform the people regarding said unauthorized person.

[0043] Lastly, a battery (not shown in figure) is associated with the device to offer power to all electrical and electronic components necessary for their correct operation. The battery is linked to the microcontroller and provides (DC) Direct Current to the microcontroller. And then, based on the order of operations, the microcontroller sends that current to those specific electrical or electronic components so they effectively carry out their appropriate functions.
