Intelligent integrated self-floating acoustic release mechanism

Abstract

The invention discloses an intelligent integrated self-floating acoustic release mechanism. The mechanism comprises a floating body, a rope bin and an acoustic releaser, the floating body is located above the rope bin, and the acoustic releaser penetrates through the floating body and the rope bin and is fixed to the floating body; the bottom of the rope bin is fixed to underwater equipment, a rope is placed in the rope bin, one end of the rope is fixed to the bottom of the floating body, and the other end penetrates through a through hole in the bottom of the rope bin and is fixedly connected with the underwater equipment; and the acoustic releaser comprises an acoustic transducer, a control circuit and a releasing module, the acoustic transducer is located at the top of the floating body, and the releasing module is located at the bottom of the rope bin and connected with underwater equipment. According to the acoustic release mechanism disclosed by the invention, the safety and reliability of release can be improved, smooth recovery of the underwater equipment is ensured, and the influence of vibration caused by water flow impact on acoustic equipment is reduced.

Description

technical field [0001] The invention relates to a release mechanism, in particular to an intelligent integrated self-floating acoustic release mechanism. Background technique [0002] The underwater acoustic response releaser integrates the acoustic response function and the release function. The deck unit is usually placed on the ship, and the acoustic releaser is bound with the underwater equipment to sink together. When the equipment needs to be recovered, the ship codes through the deck unit on the ship, and sends a specific remote control code signal to the water through the transducer. The acoustic releaser performs code group identification after receiving the remote control command, and the corresponding acoustic releaser controls the execution of the release. The unit separates the underwater equipment from the anchor block, and performs operations such as equipment recovery and maintenance, so as to realize multi-point remote control and positioning, and indicate t...

Problems solved by technology

Under deep sea conditions, this method has certain advantages, but for shallow waters, this deployment recovery method and release mechanism have the following disadvantages: First, due to the large number of offshore fishing operations, the ropes and floats are easily caught by passing ships. Damaged, entangled on passing ships or dragged by trawl nets, which will cause displacement or disconnection of underwater equipment, affecting construction; second, once the buoy is destroyed, the underwater equipment will lose its mark and it will be very difficult to find; third, floats and ropes The vibration caused by the impact of the water flow on the cable will affect the underwater equipment, especially the acoustic equipment

[0004] Based on the above problems, buoys are easily damaged, and it is very difficult to salvage and replace equipment without float indications, and buoys may affect the performance of underwater equipment, thereby affecting the construction efficiency and data accuracy of offshore exploration
