Hydraulic system of underwater multifunctional solid ballast rejection device

Abstract

The invention relates to a hydraulic system of an underwater multifunctional solid ballast rejection device. The hydraulic system comprises a first reversing valve, a one-way reversing valve, a high-pressure pressure compensator, a low-pressure pressure compensator, a first oil passage and a second oil passage, wherein the first reversing valve communicates with the high-pressure pressure compensator, the one-way reversing valve communicates with the low-pressure pressure compensator, the first oil passage communicates with the first reversing valve and a rodless cavity of an oil cylinder separately, and the second oil passage communicates with the low-pressure pressure compensator and a rod cavity of the oil cylinder separately. The hydraulic system can effectively achieve the action of submerged and floating behaviors of an underwater robot and an underwater vehicle, provide disposable hydraulic energy for rejecting solid ballast, and realize instruction rejection and fixed-depth orultra-deep emergency rejection. An auxiliary hydraulic station is adopted for debugging and loading reset, the system has the function of repeated use, and debugging and pressure setting are convenient and rapid.

Description

technical field [0001] The invention relates to the technical field of underwater mobile equipment, in particular to a hydraulic system of an underwater multifunctional solid ballast dumping device. Background technique [0002] Underwater robots and underwater vehicles use propellers to carry out long-distance underwater cruising or realize precise movement in the complex landforms of the deep seabed through multi-leg and multi-joint structures, perform stable seabed operations and travel in the deep sea, negative buoyancy diving, The working condition of positive buoyancy is an inevitable technical problem for various underwater robots and underwater vehicles. The solid dumping system is an important system for underwater robots and underwater vehicles to achieve floating and diving. Its function is to help underwater robots obtain buoyancy to float at a specified depth, and it can also discard solid ballast during the dive process. [0003] Existing underwater robots and...

AI Technical Summary

Problems solved by technology

The existing load dumping device has poor stability in the deep sea, and the way of blasting may cause safety risks. Therefore, it is necessary to develop a passive hydraulic system to provide primary energy for the solid ballast dumping device without leakage , which can guarantee the reliable use under water within a certain period
