The invention discloses a pavement speed bump power generating device integrating collecting-diverging type and continuous type power generation. The pavement speed bump power generating device integrating collecting-diverging type and continuous type power generation comprises a speed bump energy change module, a continuous power generation module and a collecting-diverging power generation module, wherein the speed bump energy change module comprises a speed bump, a return spring, and a hydraulic cylinder fixedly connected with the speed bump through a piston rod; the continuous power generation module comprises a two-position two-way electromagnetic valve, a hydraulic rectifier bridge formed by a one-way valve, and a hydraulic motor drive power generation mechanism for converting hydraulic energy into electric energy; the collecting-diverging power generation module comprises a diverging and collecting valve, a piston accumulator for accumulating energy, a pressure gauge for displaying the pressure of the accumulator, a pressure sensor for measuring the pressure of the accumulator, a throttle valve and a pressure reducing valve for adjusting speed, a hydraulic motor and a power generator for generating power, and a manual relief valve. According to the pavement speed bump power generating device integrating collecting-diverging type and continuous type power generation provided by the invention, the two-position two-way electromagnetic valve is utilized for controlling a working mode of the speed bump power generating device, and a working mode of the power generating device is determined through the traffic flow and the travel speed of the speed bump, so that the aim of improving the energy recovery efficiency is achieved.

Description

technical field [0001] The invention belongs to the technical field of energy recovery and utilization, and in particular relates to a road deceleration belt power generation device combining centralized and continuous power generation. Background technique [0002] With the development of the national economy, the number of automobiles in our country has increased year by year, and the increase in traffic volume has also caused frequent road traffic accidents in our country. Speeding is the main cause of traffic accidents. In order to control the speed of vehicles at some intersections with large traffic volumes, road deceleration belts have emerged as the times require. The speed bump controls the speed of the vehicle in a mandatory and warning manner, thereby reducing traffic accidents. While the speed bumps are widely used, the vibration energy generated by the speed bumps is often ignored when the vehicle passes the speed bumps. With the increasing development of roa...

Problems solved by technology

The device is one-way continuous energy recovery, the hydraulic motor speed fluctuates greatly, the energy recovery efficiency is low, and it does not take into account that when the traffic flow and speed of the speed bump are different, the power generation characteristics of the speed bump are different, and it needs to work in different power generation modes Down
