Abstract

The invention relates to an air inlet apparatus of an unmanned undersea craft, and particularly relates to an air inlet floating valve device of an unmanned undersea craft. The air inlet floating valve device comprises an air inlet barrel and a floater, wherein one end of the air inlet barrel is sealed, and the other end is connected with a mounted object in a sealing way; a plurality of air inlets are evenly distributed on the air inlet barrel in the circumferential direction; outside air enters the mounted object through the air inlet barrel from the air inlets; the floater is sleeved on the air inlet barrel and can rise or fall relative to the air inlet barrel; and the opening and closing of the air inlets are controlled by the lift of the floater. According to the invention, the floater can control the opening and closing of the air inlets through the automatic lift with the variation in water level; and the air inlet floating valve device has simple structure and reliable performance, and is independent of outside energy and a control systems.

Description

technical field [0001] The invention relates to an air intake device of an underwater unmanned submersible, in particular to an air intake float valve device of an unmanned submersible. Background technique [0002] The underwater unmanned submersible vehicle with internal combustion engine as the main power source belongs to a new type of underwater robot. As a kind of underwater observation and operation platform, underwater robot has been widely used in various underwater places, and has been widely used in various underwater places. [0003] Traditional underwater robots use batteries or external power sources as power, and do not need to inhale a large amount of fresh air from the air during use. This traditional underwater robot cannot realize underwater high speed (only 3~5 knots), long voyage time (only more than ten hours), long range navigation (only one or two hundred nautical miles). The new underwater unmanned submersible vehicle powered by an internal combust...
