Underwater electromechanical removal device

Abstract

The invention aims to provide an underwater electromechanical removal device, which comprises a power shaft, a mechanical separation mechanism and a cable pull-off mechanism. The mechanical separation mechanism comprises a cam, a roller, a spindle, a return spring, a bracket plate, a steel ball and a hook, wherein the cam is contacted with the roller; the roller is connected with the spindle through a pin shaft; one end of the return spring is arranged on the spindle, and the other end of the return spring is pressed on the bracket plate; and the inner side of the steel ball is pressed on the spindle, and the outer edge of the steel ball clamps the hook. The cable pull-off mechanism comprises a crank, a connecting rod, a socket plate, a socket sleeve, a cable off sleeve and a cable off shaft sleeve, wherein the crank is connected with the connecting rod; the connecting rod is connected with the socket plate; the socket plate is connected with the socket sleeve; the socket sleeve can slide in the cable off sleeve in a reciprocating mode; the end of the socket sleeve is provided with the cable off shaft sleeve; a C-shaped ring is arranged on the cable off shaft sleeve; and the power shaft is respectively connected with the cam and the crank. The removal device is compact in structure, reliable in separation and wide in application.

Description

technical field [0001] The invention relates to an underwater appliance, in particular an underwater separation appliance. 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 equipment. Due to the complex underwater operation environment, underwater equipment often faces various dangers, so it is very necessary to equip underwater equipment with a safety guarantee system. At present, the safety strategy that is often adopted is that when the underwater equipment is in danger, the secondary part of the equipment is discarded, and the important part floats out of the water relying on its own positive buoyancy. Usually, the connection between various parts of underwater equipment includes not only mechanical connections, but also electrical connections such as power cables and signal cables, such as underwater operation equipment equipped w...

Problems solved by technology

Since the cable needs to overcome the large friction between the O-ring and the sleeve when the cable is pulled off, this device is only suitable for underwater operation equipment with heavy loads

[0004] In addition, the dumping device involving the separation of the underwater mechanical body, such as the patent document No. ZL200520097153.9, entitled "Self-rescue Release Device for Underwater Operations", uses double insurance of the motor and electric squib to achieve reliable release, but Larger
