Embodiment Construction

[0030] Below in conjunction with accompanying drawing, specific embodiment of the present invention will be further described

[0031] Refer to attached picture.

[0032] The frictional electrostatic generating device of the present invention is installed on the box girder 14, and the frictional electrostatic generating device comprises a plurality of frictional electrostatic generating units 7, and the distance between the frictional electrostatic generating units 7 is about 8cm. The number of 7 is determined by the power required by the electrical equipment. The greater the number of frictional electrostatic generating units 7, the greater the power that can be provided.

[0033] The structure of the frictional electrostatic generating unit 7 is as follows: figure 1 As shown, the basic structure is a first substrate 3 and a second substrate 6 in surface contact. The first substrate 3 and the second substrate 6 are arranged left and right, and the contact surfaces of the two...

Abstract

The invention provides a bridge vibration-based frictional electrostatic power generation device. The power generation device is applied to a box girder type bridge structure and comprises a plurality of frictional electrostatic power generation units, wherein the frictional electrostatic power generation units are arranged on a side surface and a lower surface of a box girder and a part, far away from a bridge support end by 3 meters, in the bridge girder in a distribution way, the plurality of frictional electrostatic power generation units can be connected in series, electric energy which is generated vibrates with a bridge, mechanical energy generated by vibration of a box girder structure is collected, and the collected mechanical energy is converted to the electric energy for storage and power supply to power utilization equipment. The frictional electrostatic power generation units are connected in series by a wire, are internally arranged in a waterproof package material and are arranged on the side surface and the lower surface of the box girder structure and in the box girder structure, bridge vibration mechanical energy caused by an environmental dynamic load is converted to the electric energy, the electric energy can be timely stored when enough electric energy is generated, continuous power supply of the system is ensured, and brand-new environmental-friendly and green energy is provided for the bridge structure.

Description

technical field [0001] The invention relates to an energy capture power generation device for bridge structures. Background technique [0002] In today's environment where energy conservation and environmental protection are advocated, clean energy such as solar energy and wind energy have been widely used in transportation facilities, but limited by their size and layout requirements, they can only be used on a small scale as ancillary facilities. Therefore, there is a need for an energy supply device that can be used more widely and can be combined with the traffic facility structure itself as a part of the structure rather than a simple additional facility. [0003] Bridge structures often undergo large structural vibrations under dynamic loads. In bridge engineering design, structural optimization and additional vibration reduction devices are often used to control the structural vibration intensity, and the essence of vibration reduction devices is energy absorption dev...
