A hydraulic energy absorption, conversion, storage system and intelligent valve device without external power supply

Abstract

A hydraulic energy absorption, conversion, storage system comprises a hydraulic energy electric energy conversion unit and a control unit; the control unit is powered up only by the hydraulic energy electric energy conversion unit; an intelligent valve gear with no external power supply comprises an intelligent valve control unit, a hydraulic energy electric energy conversion unit, an electromagnetic pilot valve, and a hydraulic control reversing valve; the intelligent valve control unit is powered up only by the hydraulic energy electric energy conversion unit. Pipeline vibrations and hydraulic impacts harmful to equipment are smartly utilized and used for powering up the solenoid valve through hydro-electric conversion, so harmfulness is converted into benefits, thus realizing integration utilization of the hydraulic energy; the whole structure is simple, dismounting is convenient, and fault rate is low; a wireless controller is provided so as to realize remote control.

Description

Technical field [0001] The invention relates to a hydraulic energy absorption, conversion and storage system, in particular to an intelligent reversing valve used in underground equipment such as hydraulic supports. Background technique [0002] Smart valve devices, such as solenoid directional valves or solenoid directional spools, are commonly used control components in the hydraulic field. It is widely used in underground coal mines, and is widely used in underground equipment such as hydraulic supports and pillars to play a role in reversing adjustment. Under normal circumstances, the existing solenoid valve device is supplied with a battery or an external power supply, resulting in a bloated structure, especially in a poor underground environment. The battery or external power supply often causes connection failures and affects the normal operation of the solenoid valve device. use. [0003] At the same time, most of the downhole equipment is heavy hydraulic equipment, hydra...

AI Technical Summary

Problems solved by technology

Usually, the existing solenoid valve device has a battery or an external power supply for its power supply, resulting in a bloated structure, especially in the poor underground environment, and the battery or external power supply often causes connection failures, which affect the normal operation of the solenoid valve device. use

[0003] At the same time, most of the underground equipment is heavy-duty hydraulic equipment, and the hydraulic shock and vibration are relatively large. These are useless work, which will cause medium temperature rise or pipeline vibration, and will also affect the normal use of hydraulic supports, etc.

[0004] In the prior art, such as CN1185421C, CN103256278A, etc., all disclose the conversion device of hydraulic energy and electric energy, but it is mainly aimed at the recovery of throttling energy of the pipeline, and the energy is huge, so the structure of the conversion device is complicated and is not suitable for driving Small parts such as valves
