Road mechanical energy collection apparatus based on mechano-electric effect improvement

Abstract

The invention provides a road mechanical energy collection apparatus based on mechano-electric effect improvement. A piezoelectric power generation substrate is placed on a bottom plate; through holes are formed in the piezoelectric power generation substrate; connecting pieces pass through the corresponding through holes; one ends of the connecting pieces are fixed on a top plate while the other ends of the connecting pieces are fixed on the bottom plate; multiple uniformly distributed mounting blind holes are formed in the piezoelectric power generation substrate; the mounting blind holes are connected through wire grooves which are formed in the piezoelectric power generation substrate; collection circuit mounting blind holes connected with the wire grooves are also formed in the piezoelectric power generation substrate; a piezoelectric stacking unit is mounted in each mounting blind hole; a force transfer component is placed on each piezoelectric stacking unit; the top part of the force transfer component extends out of the corresponding mounting blind hole to jack the top cover; and the top plate and the piezoelectric power generation substrate are separated by the force transfer components. The road mechanical energy collection apparatus can be widely applied to road engineering, and has a good stress transfer effect, high energy conversion efficiency, quite high durability, and high overall integrating degree with an asphalt pavement.

Description

technical field [0001] The invention belongs to the field of road engineering and relates to energy collection, in particular to a road mechanical energy collection device based on improving the electromechanical effect. Background technique [0002] The road structure has accumulated considerable mechanical vibration energy under the action of hundreds of millions or even tens of billions of vehicle loads, but such a huge amount of energy is often not utilized and is naturally lost. If the piezoelectric vibration energy harvesting technology is combined with road engineering, a highway with piezoelectric power generation capacity can be developed, and a safe, reliable, and clean intelligent power generation system can be created on this basis, which can provide energy for traffic facilities along the road, and at the same time Effectively solving the problem of difficult power supply for transportation facilities along highways in remote areas has huge economic and social b...
