Air Compression and Electricity Generation by Using Speed Breaker with Rack And Pinion Mechanism

Abstract

On roads, speed breakers provided to control the speed of traffic in rushed areas. The potential energy in terms of weight of vehicle is loss on speed breaker can be utilized for useful purposes. This paper describes the potential energy of such type of energy available on roads and its utilization for useful work. The stages of development of a speed breaker device are described and the mechanism to generate electricity using rack, pinion and speed increasing gear box and generator and store compressed air with the help of piston cylinder compressor arrangement. Whenever the vehicle is allowed to pass over the speed breaker dome, it gets pressed downwards. As the springs are attached to the dome, they get compressed and the rack, which is attached to the bottom of the dome, moves down in reciprocating motion. Since rack has teeth connected to pinion there is conversion of reciprocating motion of rack in to rotary motion of pinion, but the two gears rotate in opposite direction. So that shafts will rotate with certain RPM these shafts are connected through a belt drive to the generators, which converts the mechanical energy into electrical energy. The rack is attached to piston rod of cylinder so downward stroke of rack we can use for air compression in reservoir, with help of piston cylinder arrangement. Simultaneously reciprocating piston cylinder arrangement compresses the air and stores it in the reservoir. We can use the generated electricity and compressed air for different purpose.
