Background
The linear towed hydrophone is important equipment in marine geophysical prospecting operation and has the function of receiving acoustic reflected signals of the sea bottom. In on-site walkie-talkie operation, linear hydrophones are often towed behind the survey vessel. In order to avoid interference of wake flow of the measuring ship to hydrophone acquisition signals, the towing distance of the linear hydrophone needs to be more than 20m from the stern. The geophysical prospecting operation ship needs to turn, avoid collision with an obstacle and a ship in the marine operation process, and needs to take back the towed hydrophone in time. And after the normal state is recovered, the recovered hydrophone needs to be put into water in time.
At present, a small-sized geophysical prospecting operation ship adopts a manual receiving and discharging hydrophone cable. The main method is that a worker pulls the hydrophone cable by hand and pulls the hydrophone cable onto a ship. The cable is long, and the underwater resistance is large, so that the low operation efficiency and the high working strength are caused, the hydrophone cable cannot be timely retracted in emergency, and the damage to the dragging type hydrophone equipment is inevitable.
In addition, when the aerial geophysical prospecting survey is carried out, the geophysical prospecting operation ship needs to turn frequently according to the requirement of a preset survey line, and due to the fact that the ship speed is low in the turning process, the towed linear hydrophone has the risk of being stirred into a propeller at the stern, and therefore hydrophone equipment is damaged. In addition, the influence of other ships passing through and sea obstacles and the like is often caused in the normal geophysical prospecting operation process, so that emergency measures such as steering, ship stopping, speed reduction and the like are taken by the geophysical prospecting operation ship, and the risk of leading the hydrophone to be involved in a stern propeller is also caused.
