Embodiment Construction

[0025] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0026] Such as figure 1 As shown, the present invention is a shore-based shock absorber for submarine cables, comprising:

[0027] Support shell: The support shell is used to connect with the roadbed. The shock absorber axis is placed inside the support shell, and the shock absorber tailstock is arranged at the end of the support shell. The support shell and the shock absorber axis are connected by a linkage shock absorber; the shock absorber axis is Hollow structure, the submarine cable is fixed in the middle of the shock-absorbing axis;

[0028] The linkage shock absorber includes several shock-absorbing swing arms that are rotatably connected to the suppo...

Abstract

The invention relates to a shore-based shock absorber for submarine cables, comprising: a supporting shell: a shock-absorbing axis is placed inside the supporting shell, a shock-absorbing tailstock is arranged at the rear of the supporting shell, and the supporting shell and the shock-absorbing axis are linked and damped The submarine cable is fixed in the center of the shock-absorbing axis; the linkage shock absorber includes a number of shock-absorbing swing arms that are rotatably connected to the supporting shell, and one end of the shock-absorbing swing arm is rotatably connected to the end outer wall of the supporting shell; shock-absorbing The axis is floatingly connected to the middle of the support shell through the floating rubber rings located at both ends of the support shell; on the shock absorbing axis, there are a number of line-passing seat A arrays arranged in a circular array, and each set of line-passing seat A arrays includes a number of linear arrays. Wire seat A, a number of thread passing seats B are arranged in a linear array on the shock-absorbing swing arm, and a floating steel cable is connected to the front end of the supporting shell, and correspondingly, on the wall of the supporting shell, there are holes for the floating steel cable to pass through. Cable hole.

Description

technical field [0001] The invention relates to a shore-based shock absorber for submarine cables, which belongs to the field of connection equipment for submarine cables. Background technique [0002] The connection and shock absorption of submarine cables is generally realized through the elastic buffer sleeve at the end of the submarine cable. The buffer sleeve is used to achieve excessive shear force and prevent the damage of the submarine cable due to the concentration of shear stress. However, the shock-absorbing structure of the elastic buffer sleeve Shock absorption can only be achieved by relying on the metal elasticity of the submarine cable itself. The shock absorption effect of shock absorption is limited, and it is easy to bring a large tensile burden to the insulating layer outside the cable. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a shore-based shock absorber for submarine cables to overcom...
