Abstract

The invention relates to the technical field of buoyancy balance of underwater vehicles, and discloses a water volume detection and cabin pressure alarm device of a buoyancy balance water cabin, which comprises a sealing barrel, a liquid level meter, an airtight opening sealing head, a guide rod limiting seat, a sealing end cover, a pressure switch, a watertight connector, a floater and a guide rod, one end of the sealing cylinder is open, and a sealing end cover is arranged at the open end; a liquid level meter for detecting water volume, a pressure switch for alarming cabin pressure and a watertight connector respectively connected with the liquid level meter and the pressure switch are arranged in the sealed cylinder, and the watertight connector is used for transmitting a liquid level signal and a cabin pressure alarm signal in a water cabin to the outside; the sealing end cover is provided with an airtight detection port and an airtight port sealing head; one end of the guide rod is connected with the liquid level meter, and the other end of the guide rod is provided with a floater and connected with a guide rod limiting seat. The device can measure a liquid level position signal in the water storage tank and give an overpressure alarm, and is simple in overall structure, reliable in function and easy to realize.

Description

technical field [0001] The invention relates to the technical field of buoyancy equalization of underwater vehicles, and more specifically relates to a water volume detection and cabin pressure alarm device for a buoyancy equalization water tank. Background technique [0002] Due to the change of seawater density during the voyage, the large displacement underwater vehicle will cause a large change in its floating state, which will affect the stability of the underwater navigation attitude. The buoyancy equalization system can be used to inject water into the water tank to change the Its own mass is used to realize the floating state balance. How to carry out real-time, accurate and reliable dynamic detection of the change of water volume inside the water tank and the safety pressure limit is the key to the operation of the buoyancy equalization system. To solve this problem, the system needs to be equipped with a water volume detection and cabin pressure alarm device. [0...
