Embodiment 1

[0030] As shown in the figure, a speed bump device based on PVDF piezoelectric material is mainly composed of an energy storage circuit and a power generation system.

[0031] The energy storage system of the present invention adopts MAX1811 as the main control chip to design a circuit to collect electric energy of the rechargeable battery. MAX1811 is small in size, with a size of 5.00mm*6.20mm*1.35mm. It is a highly integrated battery charger that requires few external components and is easy to control the circuit size. Moreover, it can be used for lithium battery charging.

[0032] MAX1811 has two setting terminals. When SELV is set to high, the final charging voltage of the battery is 4.2V; when it is set to low, the final charging voltage is 4.1V, which can adapt to lithium batteries with different final charging voltages. The accuracy can reach 0.5%, which can safely charge the battery. The other setting terminal is SELI, when the switch K is closed and set to high, the ...

Abstract

The invention belongs to the technical field of energy conservation and environment protection and discloses an energy-saving and environment-friendly piezoelectric power generator for a road. The energy-saving and environment-friendly piezoelectric power generator comprises an energy storage circuit, a piezoelectric power generator and a test system, wherein the energy storage circuit carries outelectric energy collection on a rechargeable battery by adopting MAX1811 as a main control chip design circuit; the piezoelectric power generator is speed bumps and is embedded into a groove; the lower end of each speed bump is connected with a pressure amplifier; a piezoelectric material is arranged at the lower part of each pressure amplifier and connected with the ground; whole piezoelectric power generation equipment is formed by a plurality of speed bumps in a parallel connection manner; and the piezoelectric test system comprises a power amplifier, a high energy exciter, a hall displacement sensor, a charge amplifier and the like. According to the energy-saving and environment-friendly piezoelectric power generator, the running gravity of a vehicle is converted into electric energy,and energy consumed by the vehicle is recovered in a manner of the electric energy. Compared with other piezoelectric power generators, the energy-saving and environment-friendly piezoelectric powergenerator has the advantages that the piezoelectric characteristics and the durability are greatly improved, and the produced electric quantity can meet the electricity demand of a bus stop light boxand the charging demand of general mobile electronic equipment.

Description

technical field [0001] The invention discloses a PVDF piezoelectric material-based deceleration belt power generation device conceived from a bus stop, and belongs to the technical field of piezoelectric power generation. Background technique [0002] Driven by global economic development, the world's total energy consumption has increased from 5.38 billion tons of standard coal in 1965 to 18.19 billion tons of standard coal in 2013, an increase of 2.4 times. In the future, the world's energy consumption will continue to grow. Fossil energy reserves are limited and non-renewable. Large-scale development will lead to accelerated depletion of resources. Now the most common ones are hydropower and thermal power generation. Hydropower generation will destroy the earth's water cycle, affect climate change, easily form extreme weather, and easily cause earthquakes and damage the ecological balance. Thermal power generation is heavily polluted by smoke and dust and uses fuel. The ...
