Abstract

The invention discloses a comprehensive-mode piezoelectric power generation unit and a road full cross-section synchronous power generation device. The road full cross-section synchronous power generation device comprises a plurality of piezoelectric power generation units, installation grooves and a force transfer plate, wherein the installation grooves are used for installing the piezoelectric power generation units, the force transfer plate is used for hermetically covering openings in the tops of the installation grooves and is in contact with an upper surface of each piezoelectric power generation plate, a total wire after each piezoelectric power generation unit is connected in parallel extends out of the installation groove, each piezoelectric power generation unit comprises a cylindrical insulation cavity and also comprises a various-mode piezoelectric sheet, the cylindrical insulation cavity is encircled by a cylindrical groove shell and a press plate at the top, and the piezoelectric sheet is arranged in the insulation cavity and is of a fan-shaped structure. Power is generated on the basis of comprehensive modes of d15, d33 and d31 of a direct piezoelectric effect, the piezoelectric sheets in different modes are arranged at different positions in the piezoelectric power generation unit according to different stress modes, the internal space and a vertical load are fully utilized, and the mechanic electric conversion efficiency is improved.

Description

technical field [0001] The invention belongs to the field of road engineering, and relates to a piezoelectric power generation device, in particular to a comprehensive mode piezoelectric power generation unit and a road full-section synchronous power generation device. Background technique [0002] By the end of 2016, the total mileage of highways in my country had reached 4,696,300 kilometers, of which 131,000 kilometers were expressways, and the number of motor vehicles was 310 million, of which 216.1 million were automobiles, increasing year by year. Considerable mechanical vibration energy has been accumulated under the impact and vibration of tens of billions of vehicle loads. If this mechanical energy can be effectively collected and converted into electrical energy, it will become another clean energy besides solar energy, wind energy, and nuclear energy. Therefore, a A piezoelectric power generation device with high energy collection and conversion efficiency is of gre...
