Rapid buoyancy adjusting device of underwater glider

Abstract

The invention discloses a rapid buoyancy adjusting device of an underwater glider. The rapid buoyancy adjusting device comprises a sealed shell and an air pump, wherein the air pump is arranged in the sealed shell and driven by a direct current motor. An integrated cartridge valve block is arranged on the front portion of the air pump. A two-position two-way normally-closed hydraulic electromagnetic valve, a two-position two-way normally-closed pneumatic electromagnetic valve and an air outlet connector connected with a high-pressure-resistant air outlet pipe are arranged on the front portion of the integrated cartridge valve block, and the other end of the high-pressure-resistant air outlet pipe is connected with an external air bag. An air inlet connector connected with an air inlet pipe is arranged on the lower portion of the integrated cartridge valve block. A seawater detector mounted on the integrated cartridge valve block is arranged on the inner side of a valve block hook, and the inner side of the valve block hook is connected with an air pressure sensor through an auxiliary hole adapter. The outlet end of the air pump is connected with a one-way valve which is mounted inside the integrated cartridge valve block, and the one-way valve is connected with an adjustable air overflow valve mounted on the lower portion of the integrated cartridge valve block. The rapid buoyancy adjusting device has the advantages that the buoyancy can be rapidly adjusted, the work time on the water surface of the glider is shortened, the severe influence caused by accidental damage to the external air bag is avoided, and debugging, installing and maintaining of the whole glider in the later period are facilitated.

Description

technical field [0001] The invention relates to an adjustment device, more specifically, the invention relates to a device for quickly adjusting the buoyancy of an underwater glider. Background technique [0002] Those skilled in the art know that when the underwater glider is working on the water surface, it is necessary to adjust the attitude of the glider to make the antenna device leak out of the water, thereby realizing communication with the glider, and the change of the overall attitude of the glider is determined by the distance between the center of gravity and the center of buoyancy of the equipment. decision, requiring corresponding adjustments in the center of gravity or buoyancy. If the antenna is completely leaked out of the water, the movement of the center of gravity must have a large stroke, so as to occupy a large space inside the glider shell. The purpose is achieved by changing the position of the center of buoyancy. To this end, a certain volume of airb...

AI Technical Summary

Problems solved by technology

[0004] (1) Since it is necessary to ensure its high-pressure working state when it is underwater, the speed of buoyancy adjustment is relatively slow;

[0005] (2) The buoyancy is adjusted in a manner similar to an air pump, and the pipeline connection takes up a large space and is complicated to install;

[0006] (3) There is no seawater detection device in the air pump system. Once the external airbag is damaged, it will cause an accident of water entering the entire glider;

[0007] (4) There is no air pressure detection device in the air pump system. Once the overflow valve is stuck, the air bag will continue to expand and rupture, which will affect the normal operation of the equipment.
