Rapid buoyancy adjusting device with water leakage detection function

Abstract

According to the rapid buoyancy adjusting device with the water leakage detection function, air in an aircraft cabin is sucked into / discharged out of an external air bag, so that water drainage and the buoyancy center of an aircraft are changed, and an aircraft deepwater hydraulic buoyancy adjusting system is assisted in rapidly achieving buoyancy and posture adjustment in shallow water; and rapid emergency diving or rapid water outlet communication of the aircraft is realized. The buoyancy adjusting device comprises an air bag, a one-way valve, an air pump, an electromagnetic valve, a four-way base body and a water leakage detection assembly. A connector a of the four-way base body is connected with the air bag and is locked at the joint through a fastener; an outlet b of the four-way base body is connected with an air outlet of the air pump through a pipeline provided with a one-way valve, and the outlet end of the one-way valve is connected with the outlet b of the four-way base body. The water leakage detection assembly installed at the connector d of the four-way base body is used for water leakage detection of the air bag.

Description

technical field [0001] The invention relates to a buoyancy adjustment device, in particular to a fast buoyancy adjustment device with a water leakage detection function, and belongs to the technical field of underwater unmanned equipment. Background technique [0002] With the rapid progress of ocean monitoring technology and the demand for deep-sea exploration, new unmanned autonomous detection platforms, such as deep-sea UUV, underwater glider, and profiling buoys, are favored by scientists and users. The detection platform is often relatively cheap, easy to deploy and salvage, and can achieve long-term, continuous and efficient observation. [0003] Such underwater unmanned autonomous detection platforms often achieve drive or attitude adjustment by changing their own buoyancy through a set of buoyancy adjustment devices. The buoyancy adjustment device is one of the core components of this type of equipment. There are mainly three existing mature buoyancy adjustment meth...

Among them, method (3) has poor reliability and large structure volume, and method (1) and method (2) are widely used

[0004] The buoyancy adjustment methods of hydraulic oil suction and discharge and seawater suction and discharge have a similar hydraulic system. It is necessary to design the corresponding circuit according to the maximum operating water depth of the aircraft, and select appropriate pumps, valves and other components. However, in the shallow water and low back pressure operating environment Under such circumstances, such a set of buoyancy adjustment system configured according to the maximum water depth appears to consume a lot of energy, respond slowly, and waste the deep water buoyancy adjustment capacity reserve
