Abstract

The invention discloses a hydrostatic pressure release device for a life raft, which comprises a casing, one side of the casing is provided with a water inlet, and the other two sides are provided with an opening and a release near the water inlet, and the opening and the release are communicated through a slideway. ; There is a diaphragm near the water inlet in the shell, and the diaphragm is fixedly connected to the inner side of the shell through a compression spring. There is a release trip in the diaphragm, and a release spring is provided between the release trip and the diaphragm. The outer end of the outer shell is fixedly connected with the rope through the opening of the shell. The design principle of the invention is simple and effective, the release is safe, the reliability is strong, and it can be used repeatedly, thereby improving the resource utilization rate and reducing the 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...
