Energy storage 19, as propulsion source, has quadruplet, and every cover is equipped with independently hydraulic control unit, does not interfere with each other, and provides pressure oil separately to an oil cylinder 17, guarantees in case of emergency have at least a pair of hydraulic ram 17 can normally move work.
Control cables has one group (one), controls the keying of Solenoid ball valve 29 in every cover hydraulic control unit by electric signal, thereby controls the operation of every oil cylinder 17.
Binding ring 5, seal ring 15, oil cylinder 17, energy storage 19, hydraulic control unit are all independently arranged on outside escape capsule 4; Control cables one end is arranged in the electric cabinet in escape capsule, after other end crossing cabin, by fast unplugg, is connected with the cable socket 27 of Solenoid ball valve 29.
Working process is as follows:
The first step: when underwater emergency discharges, personnel enter escape capsule 4, closing chamber lid.
Second step: in escape capsule 4, send electric signal by control cables, open the Solenoid ball valve 29 in hydraulic control unit.
The 3rd step: the high-pressure oil flow in energy storage 19 is to oil cylinder 17, and oil cylinder 17 promotes binding ring 5 and rotates.
The 4th step: be subject to the restriction of oil cylinder 17 strokes, when binding ring 5 rotates 15 °, binding ring 5 stops operating, and arrives disengaged position, binding ring 5 and fence release.
The 5th step: escape capsule 4 departs from deep-sea mobile workstation 1, relies on self buoyancy floating.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification.
