Embodiment Construction

[0031] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing and specific embodiment:

[0032] combine Figure 1 to Figure 7 , variable Hooke coefficient spring type submarine cable lifting mechanical claw, including grabbing structure and control structure.

[0033] The grasping structure includes a first jaw member and a second jaw member cross-hinged to each other, and each of the first jaw member and the second jaw member includes a lower jaw and an upper jaw seat.

[0034] The control structure includes a trigger component, an execution component and an action component. The action component is connected between two jaw seats, the execution component is connected in the middle of the action component, and the trigger component is connected to the lower part of the execution component. The trigger component drives the execution component to move upwards. , so as to drive the action assembly to move, and t...

Abstract

The invention discloses a variable Hooke coefficient spring type seabed cable lifting mechanical claw, which includes a grasping structure and a control structure. Using the remote control diving robot equipped with the mechanical claw can realize the salvage of submarine cables safely, conveniently and economically. The present invention utilizes the principle of changing the spring deformation coefficient. When the limit plate of the executive plate blocks the spring variable coefficient baffle plate, the three-segment spring parts generally present tension, and the two jaw parts are closed; when the trigger plate is touched, the executive plate is separated from the spring. When the variable coefficient baffle is used, the three-section spring generally presents a thrust force, and the two jaws are opened; through this principle, the grasping and releasing of the cable is realized. The invention realizes the control of grabbing and releasing through a purely mechanical method, does not need electric power, and is simple and reliable. The invention facilitates the underwater salvage work represented by the submarine cable, and provides a more convenient solution for the maintenance of the submarine cable salvage.

Description

technical field [0001] The invention relates to the field of submarine cable lifting, in particular to a variable Hooke coefficient spring type submarine cable lifting mechanical claw. Background technique [0002] After the submarine cable is laid, it runs on the seabed all year round, but the complex and harsh submarine environment will cause damage to the submarine cable. One of the more serious damages is ocean current erosion. The sediment at the bottom of the cable is gradually washed away, causing the cable to appear in a suspended section, only relying on the seabed reef as a support point. As the sea current continues to impact, the suspended section of the cable will shake and move, and the reef support point will cause serious damage to the outer skin of the cable. In the operation and maintenance process of submarine cables, it is an important link to find these damage points and repair them, and the cables need to be salvaged to the mother ship for repair. At ...
