Abstract

The invention discloses a hydrostatic pressure releasing device for a life raft. The hydrostatic pressure releasing device comprises a shell, wherein one side of the shell is provided with a water inlet, the positions, close to the water inlet, of the other two sides are independently provided with an opening and an escaping hole, and the opening and the escaping hole communicate through a slideway; a membrane is arranged at the position, near the water inlet, in the shell and is fixedly connected with the inner side of the shell through a compression spring; releasing tripping buckles are arranged in the membrane; a releasing spring is arranged between each releasing tripping buckle and the membrane; and the outer end of each releasing tripping buckle is fixedly connected with a rope through the opening of the shell. The hydrostatic pressure releasing device has a simple and effective design principle, is safe in releasing, is high in reliability, can be reused, improves a resource use ratio and lowers production cost.

Description

technical field [0001] The invention relates to an underwater automatic release device, in particular to a hydrostatic pressure release device for a life raft. Background technique [0002] At present, the principle design of the known hydrostatic pressure release device is to release the spring blade by using the increase of water depth to generate pressure, and use the impact force of the spring to push the blade to cut the ring-shaped locking rope. The disadvantages and deficiencies of this principle design are as follows: [0003] 1. The tethering rope is a closed-loop cable, and a release device needs to be added to the closed-loop cable. The release is accomplished by cutting the tether with the blade, and the blade is released by moving the diaphragm under water pressure. The principle is slightly redundant. [0004] 2. The blade is in the marine climate environment for a long time, it is easy to corrode and rust, and the reliability of release is insufficient. [0...
