Abstract

The invention discloses a deep-sea emergency reciprocating cable cutting device without a built-in power source, and belongs to the technical field of marine deep submergence detection equipment. According to the deep-sea emergency reciprocating cable cutting device without the built-in power source, a piston top rod, a hollow piston rod and a top rod cover form a hydraulic cylinder structure form, the hollow piston rod, a cylinder tail cover, a cylinder barrel, a plunger barrel and a plunger head form a hydraulic supercharger structure form, the sea water pressure is converted into the built-in hydraulic oil pressure by using the control of a two-position two-way sea water solenoid valve and a hydraulic on-off valve, the oil pressure is used as the power for shearing, after once shearing,a cutter head can be restored to the initial position by using the sea water pressure, and reciprocating and frequent shearing action of a cable is achieved accordingly; and meanwhile, as the oil-water separation design is adopted in the deep-sea emergency reciprocating cable cutting device, a main moving part can be prevented from being polluted by sea creatures.

Description

technical field

[0001] The present invention relates to a deep sea emergency hydraulic cable cutting device without a built-in power source, in particular to a hydraulic emergency cable cutting device without a special power source for deep sea underwater cable platform (such as deep sea towing body, deep sea ROV, etc.) equipment, The device can realize reciprocating multiple shearing, and belongs to the technical field of marine deep-diving detection equipment. Background technique

[0002] With the development of marine engineering, large-depth underwater towed systems or deep-sea ROVs have received widespread attention as a deep-sea exploration platform, such as deep-sea target search, deep-sea geological survey, deep-sea environmental investigation, etc. Generally speaking, due to the needs of towing or power supply and communication transmission, such towing systems or deep-sea ROV equipment are connected to the mother ship platform through towing cables or umbilical ca...
