Connection release device for escape capsule

Abstract

The invention discloses a connection release device for an escape capsule. The connection release device comprises a workstation docking fence connected with a deep sea mobile workstation, wherein an escape capsule docking fence is arranged on the top of the workstation docking fence through a locking ring; an escape capsule is arranged on the top of the escape capsule docking fence; multiple first flange structures are uniformly distributed on the outer circumferential surface of the locking ring; the first flange structures comprise clamping grooves formed in the upper part; grooves are formed in the lower parts of the clamping grooves; lower locking blocks are arranged in the grooves through first bolts; multiple third flanges connected with the clamping grooves in a matched mode are uniformly distributed on the inner side of the escape capsule docking fence along the peripheral direction; multiple second flanges are uniformly distributed on the inner side of the top of the workstation docking fence along the peripheral direction; upper locking blocks connected with the lower locking blocks in the matched mode are fastened on the second flanges through second bolts; the upper locking blocks and the lower locking blocks are arranged in an opposite matched mode and are positioned in the grooves; a cylinder is arranged on the inner side of the workstation docking fence; the head of a piston rod of the cylinder is hinged with a lower end surface of the locking ring; the cylinder is connected with a power device. The connection release device is reliable in operation.

Description

technical field [0001] The invention relates to the technical field of deep-sea escape equipment, in particular to a connection and release device for an escape cabin, which is used on a deep-sea workstation and can also be used on other underwater life-saving equipment. Background technique [0002] The deep-sea workstation has its own escape cabin. When an emergency occurs, all personnel enter the escape cabin, connect the release device to work, rotate the locking ring at a certain angle, and release the fixed connection between the escape cabin and the deep-sea workstation. The escape cabin relies on itself Buoyancy rises to the surface for assistance. [0003] The connection release device in the prior art adopts a (manually operated) rack and pinion mechanism, and its arrangement and operation will occupy the personnel space in the escape cabin; the central axis of the gear must pass through the cabin, and the reliability of the rotary seal in the deep sea environment ...

AI Technical Summary

Problems solved by technology

[0003] The connection release device in the prior art adopts a (manually operated) rack and pinion mechanism, and its arrangement and operation will occupy the personnel space in the escape cabin; the central axis of the gear must pass through the cabin, and the reliability of the rotary seal in the deep sea environment Low; the operation requires a lot of manpower, troublesome operation, and low efficiency; the rack and pinion mechanism itself is heavy, and the volume of the buoyancy material must be increased
