Built-in piezoelectric energy storage type oil leakage detection and early warning hydraulic shock absorber

Abstract

The invention discloses a built-in piezoelectric energy storage type oil leakage detection and early warning hydraulic shock absorber. The hydraulic shock absorber comprises a piston cylinder. A piston plate is installed in the piston cylinder in a sealed and sliding mode, a piston rod is inserted into one end of the piston cylinder in a sealed and sliding mode, the end, close to the piston plate,of the piston rod extends into the piston cylinder and is fixed to the piston plate, a plurality of right-angle elbows are symmetrically arranged on the inner wall of the piston cylinder, piezoelectric tubes are jointly welded between every two opposite right-angle elbows in a sealed mode, an energy storage detection sleeve is installed at the end, away from the piezoelectric tubes, of the pistoncylinder, and the piston rod is rotatably inserted into the energy storage detection sleeve. According to the hydraulic shock absorber, a plurality of arc-shaped piezoelectric patches on the piezoelectric tubes generate electric energy through the continuously changing pressure difference generated by the work of the shock absorber, an external function is not needed, and the electric intubationtube realizes the functions of real-time detection and timely alarm through the conduction of an electric fork by utilizing the characteristics of oil absorption and expansion of annular expansion resin.

Description

technical field [0001] The invention relates to the field of hydraulic shock absorbers, in particular to a built-in piezoelectric energy storage type oil leakage detection and early warning hydraulic shock absorber. Background technique [0002] During the working process of mechanical equipment, due to factors such as self-weight and load gravity, the working machinery cannot reach the ideal operating state, which will cause mechanical equipment to vibrate during the working process, and the vibration will affect the mechanical structure and processing accuracy. Therefore, most of the high-precision mechanical equipment is equipped with hydraulic shock absorbers. Hydraulic shock absorbers can effectively reduce the impact of mechanical vibration on mechanical structures and processed parts, and hydraulic shock absorbers will leak oil due to mechanical loss when they are used for a long time. The condition of the shock absorber will affect the shock absorption effect, so it ...
