Abstract

The invention discloses an underwater towed vehicle automatic detaching apparatus comprising a towing hawser, a bearing joint, a joint pin, an universal connector, a protecting cable, a shackle pin, a shackle body, and a fracture pin. The towing hawser is connected to the underwater towed vehicle through the bearing joint. The bearing joint is connected to an ear plate I of the universal connector through the joint pin and a nut. One end of the protecting cable is connected to an ear plate II of the universal connector, and the other end of the protecting cable is arranged on the shackle body. The shackle pin sequentially penetrates through an aperture on the right side of the shackle body, a through hole used for protecting a cable pedestal, and a threaded hole on the left side of the shackle body. A top boss of the shackle pin is arranged in a shackle body recess. Bottom screw thread of the shackle pin is connected with the threaded hole of the shackle body. The fracture pin penetrates through a spherical hinge opening of the universal connector and a towing hole of a towing support of the underwater towed vehicle, and is fixed by using a fracture pin nut. The apparatus is arranged on a towed vehicle. When the load on the towing hawser exceeds a preset value, the automatic detaching apparatus can be reliably fractured, such that the underwater towed vehicle can be safely detached, and a disastrous failure can be prevented from occurring.

Description

technical field [0001] The invention relates to an automatic release device for an underwater tow body, which belongs to the field of underwater tow body applications. Background technique [0002] The underwater towing body is more likely to encounter fishing nets during the towing process. Once the fishing net is towed, the towing force will increase rapidly, which may cause serious consequences such as breaking the towline, losing the towing body, or even destroying the equipment on board. At present, after the underwater tow body encounters a fishing net, it is measured that the pulling force of the towline increases, and measures are taken to stop the ship by releasing the cable to try to salvage the tow body on board. However, this method is low in reliability, difficult, destructive, time-consuming and laborious, and cannot play an effective protective role. [0003] Therefore, in order to protect the underwater towing body, an automatic release device should be set ...
