Description

Underwater releasing device and method for position indicating beacon Technical Field The invention belongs to the field of rescue of underwater vehicles, and particularly relates to an underwater release device and an underwater release method for a position indicating beacon. Background The problem of safety and lifesaving of crews is always a problem to be solved when an underwater vehicle works underwater. The underwater vehicle may encounter the risks of reef contact, storm, loss of power and the like during cruising, so that destructive accidents occur, and the personal safety of crews is seriously threatened. The life raft system is novel life support equipment effective and reliable in coping with accidents, and can provide a survival platform for self rescue or waiting for rescue after a lost crew escapes from the water surface, but survival resources such as food, fresh water and the like of the life raft are limited, the life safety of the crew can still be threatened in a cold environment, and the lost crew must be timely unfolded for rescue. Therefore, when the underwater vehicle breaks down and releases the life raft, the position-indicating beacon is often released simultaneously to send an alarm distress signal to the satellite, and the rescue organization can also arrive at the distress sea area for rescue work at the first time according to the alarm signal. The existing position indicating beacon transmitting mode mainly comprises two modes, namely manual starting transmitting mode, when an underwater vehicle is in danger, a rescuing crewman on the life raft takes the position indicating mark out of a life-saving article bag, a control switch is actively turned on to transmit signals, the transmitting time of the mode is lagged, the number of living resources in the life-saving article bag has to be reduced, and automatic transmitting mode, when the underwater vehicle is submerged, the position indicating mark is submerged to a deep depth, a hydrostatic pressure releaser cuts off a plastic bolt due to hydraulic action, the position indicating mark is separated from a protective cover to float, a magnetic switch and a water-sensitive electrode are simultaneously turned on, and an alarm is automatically sent. Therefore, the control release device of the position indicating beacon is designed on the basis of the prior art, the control release device can adapt to the complex environment when the underwater vehicle cruises, and meanwhile, when the underwater vehicle encounters an accident, the control terminal sends a starting signal to control the release device to be started so as to emit the position indicating beacon, and an alarm signal is sent to a satellite to report the current position. The device of the invention thoroughly describes the structure and the release method of the release device according to the actual situation of the underwater vehicle, and provides a reliable method for the control release of the position indicating beacon. Disclosure of Invention The invention aims to provide an underwater release device and an underwater release method for a position indicating beacon, wherein a control terminal sends a starting signal to control a shell opening device to be opened so as to transmit the position indicating beacon, the release process is stable, and the position indicating beacon is prevented from being directly released due to the influence of storm, billows and other factors.
