Technical Field

Background

With the rapid development of society, people have more and more demands on energy, and development of new energy in various countries is paid attention to. According to statistics, people flow in busy areas such as railway stations, amusement parks and the like reaches about 10 thousands of people for one day, and if potential energy difference generated by walking of people can be used for power generation, a huge power plant can be generated under feet of people. A power generation device (CN201774478U) for generating treading pressure by people uses piezoelectric ceramics and a gear mechanism to provide kinetic energy for a generator, thereby realizing the function of generating power by treading by people. The treading type pressure generating device (CN210123944U) realizes the function of treading and generating electricity by utilizing the piezoelectric ceramics and the magnetic field and the principle that the piezoelectric ceramics generates current after being pressed, but the treading plate has large size and cannot fully receive the pressure treaded by everyone, so the treading type pressure generating device is difficult to be used in places with dense stream of people. Most of the existing pedestrian flow treading pressure generating devices utilize special piezoelectric ceramics to manufacture pressure generating equipment by utilizing the characteristics of pressure discharge or adopt more complicated mechanical structures, so that the manufacturing cost and the maintenance cost are higher, and the large-scale use is difficult.

Therefore, the pedestrian flow treading pressure generating device is designed.
