Gas drive type underwater disconnecting device

Abstract

The invention provides a gas drive type underwater disconnecting device, mainly comprising three parts including a high pressure gas cylinder assembly, a high pressure electromagnetic valve assembly and a mechanical body assembly, wherein the three parts are connected through a stainless steel high pressure steel pipe and a high pressure pipe joint. A three-way ball valve is installed between the high pressure gas cylinder assembly and the high pressure electromagnetic valve assembly, and a one-way valve is installed between the high pressure electromagnetic valve assembly and the mechanical body assembly. The high pressure gas cylinder assembly is used for storing high pressure gas, the high pressure electromagnetic valve assembly is used for controlling the on-off of the high pressure gas in a pipeline, the mechanical body assembly is used for separating machinery and cables of a manipulator and underwater operation equipment, the three-way ball valve is used for changing gas circuits, and the one-way valve is used for preventing sea water from flowing into the gas cylinder after the manipulator is disconnected. When the underwater operation equipment normally works, the gas drive type underwater disconnecting device can provide accurate installation positioning for hand and shoulder joints of the manipulator and can be reliably connected with the underwater operation equipment. When the manipulator is in a dangerous condition, reliable separation of the manipulator and the underwater operation equipment can be realized so that the underwater operation equipment can be separated from the dangerous condition.

Description

technical field [0001] The patent of the present invention relates to an underwater release device, specifically a device capable of realizing emergency separation of machinery and cables between an underwater electric manipulator and an underwater operation equipment body. Background technique [0002] The ocean is rich in biological resources and mineral resources, and the development and utilization of the ocean by human beings is inseparable from underwater operation equipment. The underwater electric manipulator is a work tool that is often equipped with underwater work equipment. Due to the complex underwater operation environment, when the underwater equipment is performing underwater operations, the manipulator may be entangled by aquatic plants, fishing nets, cables or stuck by underwater stones, causing the operating equipment to lose mobility or even crash. At this time, quickly Getting rid of the manipulator is the only way for underwater equipment to save itsel...

AI Technical Summary

Problems solved by technology

The electric manipulator is different. After the mechanical body is separated, there are still power and signal cables connected, and an additional cable disconnection mechanism is required. Therefore, the above-mentioned device is not suitable for underwater electric manipulators.

[0004] In addition, the dumping device involving the separation of the underwater mechanical body, such as the Chinese patent application number 200520097153.9, in the patent document named "Self-rescue Release Device for Underwater Operation", only completes the release of the object, and does not involve the installation and positioning of the discarded object and clamping and disconnection of cables
