Remote control releaser for life raft

Abstract

The invention discloses a remote control releaser for a life raft. The remote control releaser is used for overcoming the defects of an existing life raft releasing device. The remote control releaser for the life raft comprises a raft rack for fixing the life raft, a steel wire rope and a hydrostatic release unit. One end of the steel wire rope is fixed to the raft rack, and the other end of the steel wire rope is connected with a manual releasing hook at the upper end of the hydrostatic release unit. An electric lock is arranged between the steel wire rope and the manual releasing hook, and comprises a lock body and a lock catch, wherein the lock body and the lock catch are connected with the steel wire rope and the manual releasing hook correspondingly. A telescopic electric pushing rod is arranged on the lock body, and the electric pushing rod has a first position used for locking when extending out to be inserted into the lock catch, and a second position used for enabling the lock catch to be disengaged when contracting. The remote control releaser further comprises a controller used for controlling the electric pushing rod to act. According to the remote control releaser, the electric pushing rod is used as a lock cylinder, the electric lock can be opened by a switch of the controller, and the life raft is released; operation is easy, the functions of manual releasing and water pressure releasing are achieved, and precious time is gained for passengers for self rescuing when disasters happen.

Description

technical field [0001] The invention relates to the field of marine lifesaving devices, in particular to a life raft remote control releaser. Background technique [0002] Life rafts are life-saving equipment equipped on ships to escape from dangerous areas in emergency situations or to evacuate from ships in distress. Such as figure 1 , figure 2 As shown, the life raft 1 is usually packaged and stored in a glass fiber reinforced plastic storage cylinder, and then is fixed on the special raft frame 2 on the ship's side by a steel wire rope 3 and a hydrostatic pressure release device 4 . When a disaster occurs, the manual release hook 5 on the hydrostatic pressure release device 4 can be untied and the life raft 1 can be thrown into the water, and the life raft 1 can be automatically inflated and shaped for people in distress; Manually release the life raft 1, and when the ship sinks to a certain depth underwater, the hydrostatic pressure release device 4 will automatical...

AI Technical Summary

Problems solved by technology

[0003] The release device of the above-mentioned liferaft 1 has high reliability, but its disadvantages are also obvious

Manually releasing the hook 5 requires professional operation or guidance, and ordinary passengers cannot complete it independently; the hydrostatic pressure release device 4 has a sinking stage, which will waste valuable self-rescue and rescue time
