"TRIDENT AN UNDERWATER REMOTELY OPERATED VEHICLE

Abstract

A remotely operated ROV (remotely operated vehicle), developed for inspecting the corrosion, dip of head race tunnels and inorder to conduct search and rescue operations by NDRF (national disaster response force) the inspecting department will get a fully generated report based on the inspection performed, our dashboard will provide the entire operation control being performed in the inspection department. Since it is developed with modular design, ROV uses ballast tanks for sinking and resurfacing the vehicle, employees from the inspection department are requested to check the parameters and battery health before performing an inspection, Once the rescue operation is completed the entire footage which is being captured will be sent for image pre-processing to detect for corrosion or dips in the head race tunnels. The employees will be operating and communicating the ROV(remotely operated vehicle) through tether cables for inspecting and as well as search and rescue operations. Once the inspection is completed, our software will provide a full fledged report on the. inspection done.vBy this method we can know the corrosion, dip in the head race tunnels and preventive measures that should be taken to avoid that, and the NDRF department can widely use this ROV (remotely operated vehicle) for search and rescue operations.

Specification

FIELD OF INVENTION:
Our suggested solution focuses on using underwater ROV(remotely operated vehicle)
designed with multi-functionality and cost-efficiency. Utilizing a modular design
methodology. Trident aims to enhance operational versatility by allowing for the easy
reconfiguration of its components based on mission requirements. This Approach enables
the ROV to perform a wide range of tasks by simply swapping out non-essential parts for
mission-specific components, thereby minimizing unnecessary costs and optimizing
performance for each unique mission. The modular system not only reduces the overall
cost of mission-specific implementations but also simplifies the adaptation of the ROV
for various underwater applications.
BACKGROUND OF INVENTION:
The invention discloses a remotely operated ROV(remotely operated vehicle) with
modular design that uses ballast tanks as a source for sinking and resurfacing purposes.
The project mainly focuses and targets on conducting search and rescue operations that
are performed by the NDRF(National Disaster Response force) department, apart from
that detecting corrosion, cracks and dip in the sidewall banks of head race tunnels. The
product or ROV(remotely operated vehicle) is being controlled and communicated using
tether cables. The camera is being used to capture the footage, after completion of rescue
operation the entire footage is being collected and sent for image preprocessing in order
to detect the corrosion,cracks and dip. The entire settings and the live footage of
inspection is visible through the dashboard. The ROVs information i.e battery health,
depth, speed} pressure and temperature. By this method we can easily inspect the
headrace tunnels and can efficiently perform search and rescue operations with accurate
output by NDRF(remotely operated vehicle).


COMPARISON OF PRIOR ART AND OUR DISCLOSED
SOLUTION:
Surfacing and Resurfacing of ROV is generally done by the propellers mounted on
the sides, Re-Surfacing is done using the power from the propellers and Surfacing is
done by using its own weight. But in our model surfacing and resurfacing is performed or
done by using ballast tanks.
Most of the existing solution is depending upon Box shaped design. In our design the
cylindrical design helps to distribute the pressure acting on the surface more evenly.
The materials in existing ROVs mostly used are steel tubes with aluminium shells for added weight and
this in turns creates drag. In our project the Cylindrical Design also helps to cut the drag and to
overcome the harsh flow of running water.
The Existing solutions also use the same method for communication and power supply using Tether
Cables.ln our project the use of Tether Cables ensures constant power supply to the ROV and can be
reeled in if any problem occurs.
In Existing solutions movement is only done by using propellers tilt. In our solution the
Stability is increased by using the Flaps mounted on the side.
OBJECTIVES:
The Trident project is meant to provide a solution for the National Disaster Response Force (NDRF).
NDRF carries out any underwater search operations which includes surface water rescue or deep-water
rescue. NDRF is also engaged in search of fatal victims.
The project objectives mainly focuses on :
• to offer adaptable design possibilities in accordance with the goal.
• to increase the ROV's operational depth so that it can endure the challenging underwater
circumstances.
• to offer an affordable, safe option for underwater operations.
Traditional or existing techniques of performing search and rescue operations have
frequently been ineffective, time-consuming, and prone to mistakes.


This research presents a novel approach for real-time search and rescue operations in
murky waters, surface water rescue or deep-water rescue.
We want to transform the search and rescue operations process through the use of our
ROV technology, assuring accurate and effective performance. Our solution provides
continuous, real-time inspecting capabilities, enabling NDRF inspectors to perform
search and rescue operations in an efficient way.
The system's design and implementation are covered in this paper, with an emphasis on
the hardware, software, and real-time data analysis methods used.
By making it possible for NDRF officials to precisely perform inspections.
SUMMARY:
The suggested technology solution solves a significant issue for Head Race
Tunnel Maintenance and for performing search and rescue operations done by
NDRF (national disaster response force),
of Indian railways.
Our technology intends to detect corrosion,dip of Head race tunnels and it is generally
caused by unwanted plant growth in the sidewalls of tunnels. As an inspection for this
head race tunnels can't and it is more difficult to perform manually. Our design performs
by a modular design which can be remotely operated and by merging real-time
monitoring with the help of camera. We envisage a more efficient, cost-effective, and
safer rescue and search process as a result of this creative strategy, which will eventually
benefit both the organization and make the search and rescue operations more efficient
We have been developing this project with the help of an industrial mentor from (lCF -
integral coach factory) and for the software side we have been guided by a resource
person from (infosys). Coming to the real time implementation, This study is an
important step towards the digital and safety transformation of the inspection, search
and rescue operations in the NDRF sector.
There are no patents or papers published for this problem statement as far as our
knowledge and the problem statement is taken from NDRF and it is also found in SIH -
smart india hackathon.

DETAILED EXPLANATION OF THE DEVELOPMENT:
To address the issue by our method of detecting or inspecting corrosion,dip in the head race tunnels and
to conduct search and rescue operation.Our ROV includes with technologies and components such as
Tether Cables for communication purpose, ESP32 CAM to inspect under water, 775-DC MOTOR used
for propletion and also helps move the ROV fast. Lithium ion Battery basically for power genration.
Water pumps mounted at front and back for changing the position and direction also, ballast tanks are
used for sinking and resurfacing the ROV. The waterproofed LED lights have been fixed which
provides brighter visibility while performing the inspection.. The workflow is divided into two major
stages: data collecting and automated inspecting process.
i. Data Acquisition:
Once the inspection is started, an employee from the NDRF department will perform the
operation by dropping the ROV in the location where the rescue operation need to be
conducted and real-time inspection information will be visible through the dashboard
provided, for communication purpose and also the ROV is being controlled by using
tether cables

ii. Automated control:
The information gathered in the cloud database is analyzed in real-time to verify
compliance with NDRF standards and safety laws.If any corrosion,dip of head race
tunnels is being detected then immediately it is being notified in the provided
web-portal.The collected footage is being pre-processed in order to identify the
corrosion,dip for Head race tunnels. The display unit relays system status and notifies to
on-site personnel. Historical data is saved for examination. This complete ROV system
seeks to help and improve with more advanced technologies for conducting or
performing search and rescue operations by the NDRF department. The calibration of the
devices is shown below for further work process of the system
