An underwater emergency release beacon device and method

Abstract

The invention discloses an underwater emergency release beacon device and method. The device comprises an antenna sealing cabin, a lighting part, a buoyancy part, a circuit cabin, a rope twisting disc and an electromagnetic release part, wherein the antenna sealing cabin, the lighting part, the circuit cabin, the rope twisting disc and the electromagnetic release part are connected with the buoyancy part; an antenna is arranged in the antenna sealing cabin; the lighting part comprises an LED lamp; the rope twisting disc is provided with a plurality of circles of mooring ropes, fixing joints of the mooring ropes are fixedly connected with the rope twisting disc, and free joints are connected with underwater equipment; the buoyancy part comprises a floating ball and a beacon; and one end of the electromagnetic release part is connected with the buoyancy part, and the other end of the electromagnetic release part is connected with the underwater equipment through a pull ring part. According to the underwater emergency release beacon device, when the underwater equipment breaks down, the beacon can automatically float up and transmit a GPS signal and an optical signal, so as to guide the orientation for a maintenance ship; and when the maintenance ship fishes up the device, the underwater equipment can be directly recovered by utilizing the mooring ropes connected with the beacon, the underwater diving operation does not need to be carried out, and the searching and recycling efficiency of underwater fault equipment is greatly improved.

Description

Technical field [0001] The invention belongs to the field of underwater operations, and particularly relates to an underwater emergency release beacon device and method. Background technique [0002] At present, more and more equipment is being put under water for long-term observation, such as seabed observation network. If the underwater equipment fails and loses contact, how to find and recover the underwater equipment is a major problem in the current ocean engineering. Underwater robots, underwater engineering machinery and other underwater equipment will encounter various emergencies and break down during operations, or they need to resurface by themselves after the operations are completed. In order to carry out self-rescue (or self-recovery), these devices usually need to release beacon floats with strong cables, or throw off ballast weights to provide positive buoyancy. [0003] The release device first appeared in the underwater acoustic releaser. Its working principle ...

AI Technical Summary

Problems solved by technology

[0003] The release device first appeared in the underwater acoustic release device. Its working principle is: after the device receives the underwater acoustic command, it opens the hook and releases the heavy object to generate buoyancy, so that the transponder or underwater measuring instrument can be recovered by floating up, which is inconvenient and has no Automatic monitoring function
