Abstract

The invention relates to a hydraulic system of an underwater multifunctional solid ballast dumping device, comprising 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 The first reversing valve communicates with the high-pressure pressure compensator, the one-way reversing valve communicates with the low-pressure pressure compensator, and the first oil passage communicates with the first reversing valve and the rodless chamber of the oil cylinder respectively , the second oil passage communicates with the low pressure compensator and the rod cavity of the oil cylinder respectively. The invention can effectively solve the diving and floating behaviors of the underwater robot and the underwater vehicle, provide one-time hydraulic energy for solid ballast throwing, and realize command throwing and fixed-depth or ultra-deep emergency throwing. The auxiliary hydraulic station is used for debugging and loading reset. The system has the function of repeated use, and the debugging and pressure setting are convenient and quick.

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...
