Device and method for automatically controlling airbag underwater

Abstract

The invention relates to a device and a method for automatically controlling an airbag underwater. The device comprises a device shell, a pressure sensor, an induction control circuit and a communication system, wherein the device shell is fixed on underwater equipment or fishing bait through a fixing bandage, an air bottle is arranged in the device shell, the air bottle is connected with the airbag through an air delivery pipe, the airbag is arranged outside the device shell, and a control switch for controlling the airbag to be opened and closed is arranged on the air delivery pipe. When thewater level water pressure data detected by the pressure sensor exceeds a preset pressure threshold value, the induction control circuit controls the airbag to open through the control switch, compressed air in the air bottle inflates and expands the airbag through the air delivery pipe and generates corresponding buoyancy, and meanwhile, the induction control circuit sends water pressure data and position information to a ground control station through a communication system, so that a worker searches and recycles underwater equipment or fishing baits, economic losses are reduced, and pollution and damage to the marine ecological environment are reduced.

Description

technical field [0001] The invention relates to the technical field of underwater airbag control, in particular to an underwater automatic airbag control device and method used in underwater equipment or pelagic fishing bait. Background technique [0002] At present, with the continuous exploration of marine resources, seabed exploration and deep-sea fishing have become the way for human beings to understand the underwater world and obtain resources. In the process of exploration and fishing, people will use a lot of underwater equipment and deep-water fishing bait. When the underwater equipment is abnormal during the exploration process or the fishing bait has problems with floating, then these equipment and bait will sink into the sea and become marine garbage, destroying the ecological environment of the ocean, polluting the water quality of the ocean, and endangering the survival of marine life. [0003] Therefore, how to prevent underwater equipment or fishing bait fr...
