A hydraulic control system for opening and closing the cabin door of an underwater vehicle

Abstract

A cabin door opening and closing hydraulic control system of an underwater vehicle mainly comprises an oil tank, a thermometer, a liquid level meter, a heater, an air filter, a hydraulic pump, a coupler, a motor, a one-way valve, overflow valves, two-position and two-way electromagnetic reversing valves, a pressure relay, a fine filter, a pressure gauge, an energy accumulator, servo valves, a return oil filter, a cooler, pressure sensors, a three-position and four-way electromagnetic reversing valve, hydraulic one-way valves, non-symmetric hydraulic cylinders, check valves, displacement sensors, a controller, servo amplifiers and the like. The cabin door opening and closing hydraulic control system is high in responding speed, and can achieve automatic operation of opening and closing a cabin door of the underwater vehicle. Reversing impact can be lowered, and system stability is improved. Displacement of piston rods of the hydraulic cylinders can be precisely controlled, and the precision of the system is improved. The demand for positioning and locking in the opening and closing process of the cabin door is met, and the safety of the system is improved.

Description

technical field [0001] The invention belongs to the technical field of hydraulic transmission, and relates to a hydraulic control system for opening and closing a cabin door. Background technique [0002] With the continuous exploration of the ocean by human beings, marine science and technology have been continuously developed, and the research on marine exploration equipment has become more and more in-depth. As one of the important tools for exploring the ocean world, the underwater vehicle has become an important task for scientific and technological workers to ensure the reliability and technological advancement of its basic equipment, and the safe opening and closing of the hatch is to ensure the normal operation of the underwater vehicle. It is an important link that deserves further study. [0003] At present, the door opening and closing systems of domestic and foreign underwater vehicles mostly use mechanical transmission mechanisms, that is, motors and reducers a...

AI Technical Summary

Problems solved by technology

There are also some in this field that use conventional hydraulic transmission to realize the opening and closing of the cabin door. Usually, hydraulic motors are used as power components, but the disadvantages of mechanical transmission have not been eliminated in the power transmission process, and the cabin door still needs to be opened and closed by a hydraulic motor. The reducer pulls the chain to achieve it, but the process is still unstable and the reliability is low. Once an important part of the transmission link fails, the hatch will not be able to open and close normally
