Bridge vibration energy collected anti-icing system based on piezoelectric element

Abstract

The invention discloses a bridge vibration energy collected anti-icing system based on a piezoelectric element. The bridge vibration energy collected anti-icing system comprises a plurality of building members, a road surface above the plurality of building members, electric heating elements located under the road surface, and vibration energy collecting portions arranged between each two adjacentbuilding members and used to connect each two adjacent building members, wherein each vibration energy collecting portion comprises a first cantilever beam, a second cantilever beam, a connecting member and a piezoelectric element; the piezoelectric elements are arranged on the first cantilever beams and the second cantilever beams; the connecting members are arranged between each two adjacent building members for connecting the corresponding cantilever beams on the two adjacent building members; the piezoelectric elements are connected to the electric heating elements by wires. The bridge vibration energy collected anti-icing system can collect vibration energy generated by an elevated road and a bridge to heat the electric heating elements located under the road surface, so as to prevent icing, frosting and dew condensation.

Description

technical field [0001] The invention relates to a bridge vibration energy collection anti-icing system based on piezoelectric elements, which belongs to the field of generating electric energy by piezoelectric effect. Background technique [0002] With the continuous development of our country's economy, the construction of urban elevated roads and expressways develops extremely rapidly. In urban elevated roads and highways, there are a large number of bridge structures and bridge pavements. In most parts of our country, the temperature in winter is low, which makes the elevated roads and bridges very prone to icing, which poses great hidden dangers and dangers to traffic safety. In the vast areas of Southwest my country, the air humidity is high. Under the condition of low temperature in winter, frost and condensation are prone to occur on the elevated road and bridge road surface, resulting in slippery road surface, which also leads to major hidden dangers of traffic safe...
