Hydraulic retractable fin stabilization buffer device

Abstract

The invention discloses a hydraulic retractable fin stabilization buffer device and relates to the technical field. The hydraulic retractable fin stabilization buffer device comprises a pair of transverse buffer oil cylinders and a pair of longitudinal buffer oil cylinders, wherein piston rods of the transverse buffer oil cylinders and the longitudinal buffer oil cylinders are correspondingly hinged through respective levers; a winding shaft is arranged at the middle part of each lever; a rod cavity of one oil cylinder of the transverse buffer oil cylinders and a rodless cavity of the other oil cylinder intercommunicate through a pipeline; a rod cavity of one oil cylinder of the longitudinal buffer oil cylinders and a rodless cavity of the other oil cylinder intercommunicate through a pipeline; and an intercommunicating pipeline of the transverse buffer oil cylinders and an intercommunicating pipeline of the longitudinal buffer oil cylinders communicate with respective throttling valves through respective oil supplementing valve groups. According to the hydraulic retractable fin stabilization buffer device disclosed by the invention, the problem that a fin stabilization buffer system of a current manned submersible needs to import the complete set, so the purchasing cost is high can be solved.

Description

technical field [0001] The invention relates to the technical fields of marine exploration and marine scientific research, in particular to an anti-sway buffer system for reducing shaking during retraction and deployment of underwater operating equipment such as submersibles and underwater robots. Background technique [0002] In marine exploration and marine scientific research, underwater equipment such as manned submersibles and underwater robots need to be placed on the sea surface from the working mother ship and recovered from the sea surface to the working mother ship. During the retraction process of the manned submersible, the working mother ship follows When the wave moves up and down, the manned submersible will sway in both horizontal and vertical directions. In order to reduce the adverse consequences caused by the sway to the submersible or the personnel inside the submersible, an anti-sway buffer system is needed; the existing The working principle of the anti...
