Hydraulic type piezoelectric-electromagnetic combined power generation system

Abstract

The invention relates to a hydraulic type piezoelectric-electromagnetic combined power generation system. The system is composed of an energy accumulator and a power generation device; one end of thepower generation device is communicated with the energy accumulator through a pipeline; the other end of the power generation device is communicated with an applied hydraulic system; the energy accumulator plays a role in stabilizing the pressure of the applied hydraulic system; in a pressure stabilization process, the energy accumulator is continuously filled with or discharges liquid, the powergeneration device generates power by using pressure oil flowing into or out of the energy accumulator; and the power generation device is composed of a shell, a combined power generation unit set anda turbine driving assembly, wherein the shell is of a circular-tube-shaped structure with a shaft shoulder boss, the combined power generation unit set is mounted in a radial hole in the shaft shoulder boss of the shell, and the turbine driving assembly is mounted in a flow passage of the shell. The hydraulic type piezoelectric-electromagnetic combined power generation system of the invention cannot only realize a power generation function, but also effectively stabilize the pressure fluctuation of the system and inhibit pressure impact. The hydraulic type piezoelectric-electromagnetic combined power generation system has the advantages of structure simple, size small, flexible installation, and convenience in integrated design.

Description

technical field [0001] The invention relates to a piezoelectric-electromagnetic composite power generation device, in particular to a piezoelectric-electromagnetic composite power generation system applied in a hydraulic system. Background technique [0002] With the development of hydraulic technology, more and more sensors and micro-electromechanical systems are applied to hydraulic systems. However, the traditional power supply method supplies power to external power sources. Therefore, a large number of wires have to be inserted into the system, resulting in hydraulic pressure. The power lines of the system are complicated, which increases the difficulty of system installation and maintenance, and seriously affects the system integration design. Therefore, providing an internal power supply mode of the hydraulic system is of great significance for simplifying the system and integrating the design. [0003] In hydraulic systems, pressure fluctuations and shocks are very ...
