Design and Development of Semi-Automatic Water Tank Cleaning Machine

The aim of this project is to develop a mechanical system for cleaning water tanks, incorporating two primary mechanisms: a rack and pinion mechanism and a reciprocating four-bar linkage mechanism. The rack and pinion mechanism enables the vertical movement of the entire cleaning system, allowing it to reach different sections of the tank. This movement is controlled via a switch-operated control unit. The four-bar linkage mechanism is connected to a motor shaft and is responsible for scrubbing the tank’s inner walls. PVC brushes are attached to the ends of the four-bar linkage, ensuring effective cleaning. The linkage is designed to be adjustable, accommodating various tank diameters. When the motor is activated, the four-bar linkage rotates, and the attached brushes clean the tank walls through a reciprocating motion. This project aims to minimize human effort and eliminate the health risks associated with chemical exposure and manual entry into water tanks for cleaning. By automating the process, the system enhances efficiency, safety, and effectiveness in maintaining hygienic water storage conditions.
