Underwater cable pulling-out mechanism

Abstract

The invention aims to provide an underwater cable pulling-out mechanism which comprises a power shaft, a crank, a connecting rod, a socket plate, a socket sleeve, a cable pulling-out sleeve and a cable pulling-out shaft sleeve; the crank is connected with the connecting rod; the connecting rod is connected with the socket plate which is connected with the socket sleeve; the socket sleeve can slide in a reciprocating mode in the cable pulling-out sleeve; the cable pulling-out shaft sleeve is installed at the end part of the socket sleeve, and the cable pulling-out shaft sleeve is provided with a C-shaped ring; a plug sleeve which is used for placing the cable plug is installed beside the cable pulling-out shaft sleeve; the cable socket is installed in the socket sleeve; and the power shaft is connected with the crank. The underwater cable pulling-out mechanism does not need to overcome external water pressure; the required separating force is small; the pulling-out process has nothing to do with the gravity of abandoned equipment, and is driven by the crank; the separation is reliable; and when a plurality of cable pulling-out units are adopted, the sequential pulling-out of multiple cables can be realized.

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
