Washing type air purifier based on selective sinking speed bump

Nowadays, with the development of science and technology, the extensive use of cars has caused pollution to the environment. The roads for cars are generally equipped with speed bump, which waste considerable energy while slowing down. Based on the above situation, the project team designed a Washing type air purifier device consisted of three parts of falling speed bump, transmission mechanism and air purifying device. Through the cooperation of the gear and rack, connecting rod, flywheel and chain and other mechanical structures,the device can recover and reuse the energy wasted by vehicles passing through the speed bump at an appropriate speed, and finally achieve the effect of purifying the air. For the vehicles passing by at high speed, the speed bump is selectively kept without sinking, and the original punishment mechanism of speed bump is still retained for such vehicles. The coordination of each part effectively alleviates the problem of energy waste and air pollution when the car passes through the speed bump, which has high practical value and popularization value.
