Embodiment Construction

[0017] The implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0018] See figure 1 , the present invention includes an emergency dumping unit and an explosion bolt 3, the emergency dumping unit includes a sealed casing 9, the casing 9 is composed of a bottom casing and a cover casing threaded and sealed, and a sealing ring is installed between them, and the casing 9 is a flow Linear, in order to reduce the gliding resistance in the water under the situation of being beneficial to dumping the present invention in an emergency, shell 9 is made of anti-corrosion aluminum alloy material. An emergency dumping electric control device and an auxiliary counterweight 7 are installed in the shell 9 . The ignition terminal of the explosive bolt 1 passes through the sealed casing 9 , and a sealing ring is used to seal between the explosive bolt 1 and the cover of the casing 9 . See figure 1 , figure 2 , the emergenc...

Abstract

The invention discloses an emergency ejection device of an underwater glider, comprising an emergency ejection unit and an explosive bolt, wherein the emergency ejection unit comprises an enclosed shell, an emergency ejection electric control unit and an auxiliary counter weight are arranged in the shell, the ignition end of the explosive bolt penetrates the enclosed shell, the emergency ejection electric control unit comprises a water pressure sensor, an output signal of the water pressure sensor is connected with the input end of a voltage comparator to compare with the reference voltage of the submerged depth of the underwater glider, the output end of the voltage comparator is connected with a switching circuit, the input end of the switching circuit is connected with the input end of a relay, and the output end of the relay is connected with the ignition circuit of the explosive bolt. According to the invention, the underwater glider can be floated by emergency ejection when there is a failure or other emergency circumstances during a voyage, and the safe recovery of the underwater glider body can be effectively guaranteed; by arranging the auxiliary counter weight in the enclosed shell, the configuration or adjustment of the underwater glider becomes convenient.

Description

technical field [0001] The invention relates to an underwater vehicle, in particular to an underwater glider without a propulsion system. Background technique [0002] An underwater glider is an underwater vehicle without a propulsion system. It only relies on the built-in actuator to adjust the position of the center of gravity and the remaining buoyancy to control its own movement. It is a new type of underwater vehicle or underwater robot. It is equipped with Various sensors for long-term and large-scale marine environment detection and monitoring. The disadvantage of the existing underwater glider is that it does not have an emergency dumping device, and the glider fails to float when it is under water or in an emergency, and there are potential safety hazards. Contents of the invention [0003] In view of the above-mentioned shortcomings of the existing underwater glider, the applicant of this patent provides an emergency dumping device for the underwater glider, so ...
