INTRODUCTION
‰ Drainage systems are essential components of urban infrastructure, managing
rainwater, wastewater, and other types of runoff to prevent flooding and
maintain public sanitation. However, these systems frequently face issues with
blockages due to the accumulation of waste materials such as plastic, silt,
leaves, and other debris.

‰ To reduce health risks in manual drainage cleaning, this project introduces a

semi-automated system that uses motorized mechanisms to safely remove
solid waste, protecting workers and preventing blockages and flooding.

PROBLEM IDENTIFICATION
ƒ The main incident that leads to our problem
identification is that the death of a sanitation
worker at Thiruvananthapuram canal who works
to clean the drainage manually and that leads to
his tragic death inside the drainage.
ƒ We identified that there were no any safety
around the drainage while working inside the
drainage.
ƒ The main reason is that there is no any proper or
continuous waste collection from the drainage.
So the wastes are accumulated largely inside
the canal. This leads to difficulties for the people
who were worked inside the canal.
ƒ This situation is not only important while
happened in Thiruvananthapuram but it is a
serious issue that is facing in our society.
PROBLEM STATEMENT
• To collect the wastes from the drainage continuously without affecting the human lives, there is no any proper
solution present till now.

• So in order to solve this problem we identified a solution that is properly suitable for this kind of problems.
SOLUTION
So our project Semi automated urban cleaning system is a perfect solution for the problem that is
identified and stated above.
OBJECTIVES
‰ To design a portable and adaptable system for various drainage setups.
‰ To promote a cleaner environment by minimizing waste in public drainage
To increase efficiency through continuous waste collection and minimal
manual labor.
‰ To prevent blockages and flooding by regularly removing drainage debris.
‰ To create a cost-effective and easy-to-maintain system for broad
applicability.
METHODOLOGY
1. Problem Identification and Research
ƒ Define the Issues: Start by analyzing existing drainage problems, including the health hazards
faced by workers, inefficiencies in manual cleaning, and environmental impacts of blockages.
ƒ Literature Review: Research previous works on automated and semi-automated drainage
systems. Identify gaps in current methods to establish a baseline for your design and
objectives.

2. Objective and Requirement Setting

ƒ Set Clear Objectives: Outline project goals, such as enhancing safety, improving efficiency,
creating a cost-effective system, and reducing environmental impact.
ƒ Establish System Requirements: Define technical specifications for the cleaning system,
including material durability, motor specifications, and waste-lifting capacity.
3. System Design
‰ Component Selection: Select the core components:
ƒ Frame: Choose durable, rust-resistant materials like mild steel.
ƒ Motor: Use a DC motor with sufficient torque to drive the lifting mechanism.
ƒ Chain and Sprocket: For waste-lifting operations.
ƒ Collection Bin: Design to allow for easy disposal of accumulated waste.
‰ 3D Modeling and Simulation: Use CAD software (e.g., CREO, SolidWorks) to create detailed designs
of the system. Simulate stress and load to ensure stability under operating conditions.

4. Design Calculations
‰ Motor and Torque Calculations: Calculate the required motor power and torque based on expected
load, lifting height, and speed.
‰ Structural Calculations: Assess the frame’s strength and stability under weight, including force and
stress analysis.
‰ Energy Consumption: Estimate power needs and battery specifications to ensure reliable operation.
5. Fabrication Process
ƒ Assemble the Frame: Weld and assemble the frame based on the CAD model dimensions.
ƒ Install Components: Attach the motor, chain, sprocket, and lifters. Ensure alignment for smooth
operation and minimal friction.
ƒ Set Up Collection Mechanism: Secure the collection bin and verify its accessibility for waste
disposal.

6. Experimental Setup
ƒ System Placement: Install the system across a drainage line, positioning it to allow only water to
flow through while capturing solid waste.
ƒ Calibration and Testing: Run the system under controlled conditions to calibrate speed, lifting
efficiency, and waste capacity.
7. Data Collection and Analysis
ƒ Measure Efficiency: Track the system’s performance, such as waste collection speed, motor
efficiency, and the system’s ability to prevent blockages.
ƒ Evaluate Durability: Test the frame and components over time to assess wear and
resistance to corrosion.
ƒ Cost-Effectiveness Assessment: Calculate operational costs compared to manual methods,
including labor savings and maintenance expenses.

8. Final Adjustments and Improvements

ƒ Optimize Based on Results: Make adjustments based on experimental data. For instance,
increase motor power if lifting is insufficient or enhance bin size for more waste capacity.
ƒ Finalize Design for Practical Application: Adjust the design for easy portability, durability,
and scalability for various drainage conditions.

 CALCULATION FOR THE SELECTION OF ELECTRIC MOTOR
Calculation parameter: ( The values are corresponds to our model and the values may change according to
the scale of operation and therefor the capacity of equipment varies according to the scale of operation)
1. Speed of motor : RPM
2. Torque of the motor : N-m
3. Power of the motor : Hp

Power = Torque * Acceleration

Torque = Power/ Angular speed

Perspective

Conveyor is a machine, which doing a work

Power = work / Time

Number 1
Length of conveyor = 2m
Width of coveyor = 200mm
Thickness of conveyor = 9mm
DESIGN CALCULATION FOR MODEL
Length of conveyor= 4m
Width of conveyor=2m
Total carrying load = 50 kg
Mass of belt= Total area x Unit density(=2.5 kg/݉ଶ )
= ( 4 x2) x 2.5
=20 kg
Belt material used is WOVEN NYLON.

Total load on conveyor= Total carrying load + Mass of belt

=50 + 20
=70 kg
