Project Name : Sewer Maintenance Bot
Project Theme: Community Health & Environment
Objective/Aim: The main objective of our project is to save the lives of sewage cleaners and workers who die every year due to suffocation in the man holes. This happens because of the release of harmful gases such as Methane and Carbon Dioxide due to incomplete decomposition of wastes. High concentration of such harmful gases leads to insufficient supply of oxygen to the lungs.
Scientific Principle Involved:
The Suction pump works on the principle of Positive displacement. A partial vacuum is generated by increasing the volume of a Container. This creates a difference of Pressure inside and outside the Container. This is the principle behind the Positive Displacement.
The sensitive material of MQ-6 gas sensor is SnO2, the filament of the sensor has lower conductivity in clean air.
Material Used:
Metal Chassis, MQ-6 sensor, PIC 16F169 programmed IC Resistor, Battery, Transistor, Diodes, Switches, IC Base and conducting wires, Metal Wheels, Pulley system, Motors and Axles
Utility and Further Scope of the Project: This project detects the harmful gases resent inside manholes and evacuates it with the help of a suction pump. The project can be totally automated and made even compact, attached with an additional cleaning system, which would not require any human intervention inside the manholes or sewers. The Gas harvested in the process of evacuation could be stores and passed through inorganic materials and anaerobic bacteria, so that it gets
converted into biogas which can be used as fuel.
