Embodiment Construction

[0025] In the figure, 1. Loaded unit, 2. Piezoelectric element, 3. Electrical control part, 4. Bottom plate, 5. Slide plate, 6. Support rod, 7. Lower spring, 8. Upper spring, 10. Piezoelectric material Group, 11. Elastic plate, 12. Protective ring, 13. Electrode leads.

[0026] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] Such as figure 1 As shown, the piezoelectric generating device of the present invention includes three parts: a load unit 1 , a piezoelectric element 2 , and an electrical control unit 3 . Due to the impact and vibration of pedestrians and vehicles, the load-bearing unit 1 is subjected to force and vibrates, thereby outputting a continuously reduced pulse-type impact force, and at the same time transmitting the impact pressure to the piezoelectric element 2, which is used to receive the support components. The transmitted impact pressure is output by the positive pie...

Abstract

A piezoelectric power generation device based on urban roads disclosed by the invention includes three parts: a load receiving unit, a piezoelectric element, and an electrical control unit. Among them, due to the impact and vibration of pedestrians and vehicles, the load-bearing unit is subjected to force vibration, thereby outputting a continuously decreasing pulse-type impact force, and at the same time transmitting the impact pressure to the piezoelectric element; the piezoelectric element is used to receive the impact transmitted by the supporting part Pressure, output voltage and current signals from the positive piezoelectric effect to the electrical control part, the electrical control part includes piezoelectric material groups, elastic plates, protective rings, and electrode leads; the electrical control part is connected to the electrode leads of the piezoelectric element for The voltage and current output from the piezoelectric element are detected, converted, stored, and indicated.

Description

technical field [0001] The invention belongs to the field of new energy, and relates to generating electricity by using piezoelectric materials, in particular to a device for generating electric energy by using the impact energy of automobiles or pedestrians on the road surface in urban roads and making full use of it. Background technique [0002] At present, street lamps, signal lights and other road administration facilities used in urban and suburban roads generally use AC power grid or DC power grid to provide energy, because the existing road administration power grid is dominated by medium and low voltage power grids, and the power loss of long-distance low voltage power grids is astonishing. , and the installation, use and maintenance of road facilities are complicated and require huge investment, which is particularly prominent in today's increasingly scarce energy. Traditional energy sources such as wind power, hydropower, solar energy, nuclear energy, and steam en...
