A multi-functional hoisting winch for recovery operation of manned submersible

Abstract

The present application discloses a multifunctional lifting winch for manned submersible recovery operations, including a lifting winch assembly, a reducer, a hydraulic motor, and a hydraulic control system. The hydraulic motor is connected to the first pipeline and the second pipeline of the hydraulic control system. Pipeline, the hydraulic control system includes: winch control valve group and accumulator valve group; winch control valve group includes: the output ends of the solenoid valve are respectively connected to the first pipeline and the second pipeline, and the input ends of the solenoid valve are respectively connected to The balance valve is connected in series with the second pipeline, the pilot control valve of the balance valve is connected with the first pipeline, and the proportional relief valve is connected in parallel between the first pipeline and the second pipeline; The accumulator valve group includes a pressure reducing valve, a sequence valve and two accumulators arranged in parallel, and the accumulator valve group is used for supplementing oil to the first pipeline and the second pipeline. Through the technical solution in the application, the constant tension pretension of the cable in the hoisting winch is realized, and the impact impact when the submersible leaves the sea surface is reduced.

Description

technical field [0001] The present application relates to the technical field of diving equipment, in particular, to a multifunctional hoisting winch for manned submersible recovery operations. Background technique [0002] Deep-sea science is one of the important directions in the frontier of science, and deep-sea scientific research relies on technical means and equipment support. Manned submersibles, as a particularly important deep diving equipment, can be used to perform tasks such as underwater investigation, geological exploration, sample collection, pipeline maintenance, and salvage and life-saving. When manned submersibles are operated, a special hoisting system is required to deploy the submersible from the deck to the water surface or recover it from the water surface to the deck of the mother ship using a lifting winch. [0003] Due to the large weight and shape of the manned submersible, it often operates in severe sea conditions. The combined effects of wind, ...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, the hoisting winch function of the hoisting system of the manned submersible is often relatively simple, and the operation adaptability in complex sea conditions is not ideal

In particular, when the hydraulic motor of the winch fails, the system does not have the emergency recovery operation capability of the submersible, which seriously affects the safety of the submersible and the submersible equipment.
