Description

Technical Field

[0001] The invention belongs to the technical field of energy collection, and in particular relates to an electromagnetic power generation speed reduction belt device driven by hydraulic pressure. Background Art

[0002] In recent years, with the increase in the number of motor vehicles in my country, problems such as traffic congestion and exhaust pollution have become increasingly serious. Smart transportation technology uses the Internet of Things and automatic control to improve the efficiency of the transportation system, but it is difficult to power the equipment. Speed ​​bumps are installed on roads with dense traffic. When a car passes through the speed bumps, part of the kinetic energy is dissipated during the collision and suspension buffering process, and no real utilization is achieved. Speed ​​bump power generation devices achieve energy conservation and emission reduction, solve the power supply problem of the transportation Internet of Things, and have become a hot topic of research.

[0003] The existing speed bump power generation device has a complex structure, low reliability, high cost, low energy efficiency, and is difficult to deploy in practice, and cannot effectively utilize the kinetic energy of the car passing through. In the existing speed bump power generation device, the top parts move up and down under the impact of the vehicle, absorbing the kinetic energy of the vehicle to achieve energy conversion, but the narrow and flat structural characteristics of the speed bump limit the vertical movement space of the transducer component. Therefore, the existing power generation speed bump often requires excavation of the road surface to form a deep ditch to install the power generation equipment in exchange for greater energy conversion efficiency. This method will increase costs and limit the promotion of power generation speed bumps, which is very inconvenient; in 2022, Xu Yanyan and Deng Yuanchao designed a crank-connecting rod mechanism in the foundation pit below the speed bump in the paper "Design of Automobile Speed ​​Bump Energy Recovery Device Based on Crank-Connecting Rod Movement". In the process of the car compressing the speed bump, a driving force is given to the crank-connecting rod mechanism, and the upper end of the crank-connecting rod is forced to reciprocate in the vertical direction under the action of the spring. However, since the foundation pit and drainage system require a large vertical space, the actual application requires excavation of the road surface, which is difficult to deploy. The use of hydraulic transducer can avoid the problem of complex mechanical structure and large space occupation, but the complexity of the hydraulic method is too high. In the pure hydraulic power generation method, the wheel squeezes the piston, causing the oil in the oil chamber to flow from the one-way valve into the accumulator, and the hydraulic pump converts energy, and the hydraulic motor drives the generator to rotate and generate electricity. However, the hydraulic components and pipelines of the hydraulic accumulator will cause partial pressure loss, the system is complex and prone to leakage, and the efficiency of one-way continuous energy recovery is low. For example, Wang Fujie designed a system for generating electricity using the kinetic energy of a moving vehicle in "A Power Generation System Using the Kinetic Energy of a Moving Vehicle". The input and output ends of the hydraulic pump under the speed bump are connected in series with a one-way valve and are connected to the oil tank and the hydraulic motor respectively through pipelines. However, the device is a one-way continuous energy recovery, the hydraulic motor speed fluctuates greatly, and the energy recovery efficiency is low. Summary of the invention
