Embodiment Construction
[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0026] The road deceleration belt power generation device based on bistable vibration of the present invention, such as figure 1 As shown, it includes a deceleration belt 1 arranged on the road surface of the expressway. The deceleration belt 1 includes an arched part on the road surface and a vertical support column embedded in the ground. The bottom surface of the arched part is fixed with two sets of elastic components for The elastic potential energy is stored to provide the movement recovery force of the speed bump 1. Two groups of elastic components are symmetrically located on both sides of the support column. One end of each group of elastic components is fixed on the horizontal bottom plate 17, and the surface of the bottom plate 17 is fixed on the two ends of the buckling beam 16. The buckling The surface of the beam 16 is fixedly c...

The road speed bump power generation device based on bistable vibration disclosed by the present invention includes a speed bump. The speed bump includes an arched part and a support column. The bottom surface of the arched part is fixed to two sets of elastic components, and the two sets of elastic components are located symmetrically on the support column. On both sides, one end of each group of elastic components is affixed to the horizontal base plate, the surface of the base plate is affixed to both ends of the buckling beam, the surface of the buckling beam is affixed to the bottom surface of the support column, and the center of the support column runs through the side wall with a through groove , there is a driving component inside the through groove, and the driving component is connected to the power generation component; the two side walls of the supporting column with the through groove are also opened with limiting grooves, the limiting grooves are located on both sides of the through groove, and the limiting components are installed inside the limiting groove . The device of the present invention adopts a bistable vibration mode, which can capture the pulse excitation energy of the vehicle passing through the deceleration belt to a large extent, so that the deceleration belt can generate a large movement under the pulse excitation of the vehicle, and make the deceleration belt reciprocate between two balance points, Thereby greatly improving the energy conversion rate.
Description
technical field [0001] The invention belongs to the technical field of energy recovery equipment, and in particular relates to a power generation device for road speed bumps based on bistable vibration. Background technique [0002] Since the reform and opening up, people's living standards have been improving day by day, and the industrial level has also been improving day by day. The resulting problems have gradually emerged. my country is not an energy-rich country. In order to obtain more energy to meet people's daily needs, various power generation devices have been born, such as: thermal power generation, nuclear power plants and wind power generation. Although these large-scale power generation devices are used more and more widely, there is still no better recovery device for some energy that can be recycled in life. For example: with the development of expressways, speed bump devices are often installed in areas with concentrated traffic for safety. The interaction...
