Bridge pier stud with power generation device

Abstract

The invention provides a bridge pier stud with a power generation device, and belongs to the technical field of bridge equipment. The bridge pier stud comprises a pier stud, the power generation device is arranged on the outside of the pier stud, and comprises an upper fixed plate, a connecting column, a sliding rod, a lower fixed plate and a driving mechanism, the upper fixed plate is horizontally fixed on the pier stud, the lower fixed plate is horizontally fixed on the pier stud, the upper fixed plate is provided with a plurality of first perforations, the lower fixed plate is provided witha plurality of second perforations, the sliding rod is inserted into the first perforation and the corresponding second perforation, an upper limiting position plate is fixedly arranged at the upperend of the sliding rod, the lower end of the sliding rod is fixedly provided with a lower limiting plate, the upper sleeve of the sliding rod is sleeved with a pressing spring, the pressing spring ispositioned between the lower fixed plate and the lower limiting plate, a plurality of piezoelectric sheets are arranged between the sliding rod and the connecting column, and the driving mechanism candrive the sliding rod to slide up and down along the first perforations and the second perforations to cause bending deformation of the piezoelectric sheets. The bridge pier stud with the power generation device can utilize the water flow around the pier stud to achieve power generation and is green and environment-friendly.

Description

technical field [0001] The invention belongs to the technical field of bridge equipment and relates to a pier column with a power generating device. Background technique [0002] Piers are substructures that support the bridge deck structure and transfer the constant section and vehicle live loads to the foundation. [0003] The pier of the bridge over water is set in the water all the year round. When the water flows through the pier, due to the obstruction of the pier to the water flow, the water flow will be divided into two streams at the pier and the flow speed will be accelerated. The two streams will converge and collide behind the pier to form a vortex and scour the pier. The surface of the bridge will destroy the structural strength of the bridge piers and greatly shorten the service life of the bridge. In addition, the flow energy around the piers was not utilized. Contents of the invention [0004] The object of the present invention is to solve the above-ment...
