Description

Technical Field

[0001] The utility model relates to a fixing device for stabilizing a submarine cable, belonging to the technical field of submarine cable laying. Background Art

[0002] With the rapid development of offshore wind power industry, my country has built a number of submarine cable transmission projects. In these cross-sea transmission projects, submarine cables are important equipment connecting substations or converter stations at both ends. Since submarine cables are subjected to the complex effects of waves, currents and floating body movements for a long time, they will be repeatedly pulled and pulled, which may easily cause fatigue failure of the submarine cables. Therefore, in order to maintain the overall linear shape of the submarine cables while ensuring the safe operation of the submarine cables, it is usually necessary to install some underwater fixing devices on the submarine cables.

[0003] The existing submarine cable fixing device is generally in the form of a base plus a tether clamp, which uses the clamp to clamp the submarine cable and connects the clamp to the base through a tether, which has a certain displacement limiting effect. However, under the action of waves and currents, the submarine cable will produce axial reciprocating motion. Under the clamping restriction of the fixing device, torsional friction is generated between the submarine cable and the clamp at the clamping point. Long-term friction can easily cause external damage to the submarine cable, thereby reducing its protective effect and service life. Therefore, a fixing device for stabilizing the submarine cable is urgently needed to solve the above-mentioned problems. Utility Model Content

The utility model has a reasonable structure, simple operation and convenient use. It can not only clamp and fix the submarine cable to ensure the safe operation of the submarine cable, but also avoid friction between the submarine cable and the fixing device, thereby improving the protection effect and service life.

DETAILED DESCRIPTION

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figure 1-Figure 4The utility model provides a technical solution: a fixing device for stabilizing a submarine cable, comprising a mounting base 1, an expansion bolt 2, a stabilizing component 3, a mounting component 4, a waterproof guard plate 5, a matching leather tube 6, a metal fastener 7 and a smooth cushion layer 8. Positioning holes are opened around the mounting base 1, and the positioning holes are equipped with expansion bolts 2. The waterproof guard plate 5 is installed on the stabilizing component 3, and the mounting component 4 is arranged above the stabilizing component 3. The matching leather tube 6 is assembled in the mounting component 4, and the left and right ends of the matching leather tube 6 are provided with metal fasteners 7. The stabilizing component 3 comprises a mounting seat 31, a stabilizing compartment 32, a reinforcing spring column 33, a docking block 34 and a composite spring rod 35. The bottom of the mounting seat 31 is fixed to the mounting base The surface of the plate 1 is provided with a plurality of reinforcing spring columns 33 in the stabilizing chamber 32 on the mounting seat 31. The top of the reinforcing spring column 33 is connected to the bottom of the composite spring rod 35. A docking block 34 is also provided on the top of each composite spring rod 35. The stabilizing component 3 is connected to the bottom of the mounting component 4 through the docking block 34. The mounting component 4 includes an arc-shaped mounting pad 41, a placement groove 42, a reinforcing buckle 43, a buffer gasket 44 and a buckle switch 45. The docking block 34 is fixed to the bottom of the arc-shaped mounting pad 41, and a placement groove 42 is provided on the upper surface of the arc-shaped mounting pad 41. A reinforcing buckle 43 is added between the two groups of arc-shaped mounting pads 41, and the buckle switch 45 of the reinforcing buckle 43 is provided on the arc-shaped mounting pad 41 on the same side.

[0020] As the first embodiment of the utility model: the metal fasteners 7 at the left and right ends of the matching leather tube 6 are made of metal sheets with high density and strong corrosion resistance. This design uses the connection between multiple metal fasteners 7 to facilitate the twisting and friction of the matching hose 6 at different angles, reduce wear and protect the submarine cable. The inner layer of the matching leather tube 6 is also specially provided with a smooth cushion layer 8. This design adds a smooth cushion layer 8 inside the matching leather tube 6, which helps to increase the smoothness of the submarine cable when passing through the matching leather tube 6 and reduce the loss caused by surface friction. The overall length of the reinforcement buckle 43 conforms to the width of the two arc-shaped mounting pads 41, and the reinforcement buckle 43 is made of plastic as a whole. This design utilizes the characteristic that plastic is not easy to degrade. , which helps to further stabilize the connection between the submarine cable and the fixing device. The top of the reinforcing spring column 33 and the bottom of the composite spring rod 35 are fixed together by welding, and the interface is located on the waterproof protective plate 5. This design uses two spring combinations. It can not only utilize the large load characteristics of the composite spring rod 35 to enhance the bottom bearing capacity, but also facilitate swinging with the help of the reinforcing spring column 33 to avoid breakage caused by swinging of the submarine cable. Buffer gaskets 44 are added to both sides of the placement groove 42. This design helps to clamp the side of the placement groove 42 with the help of the buffer gasket 44, which is conducive to better positioning the submarine cable on the arc-shaped mounting pad 41 after passing through the matching leather tube 6, thereby enhancing firmness.

[0021] As a second embodiment of the present utility model: when installing a fixing device for stabilizing a submarine cable, it is first necessary to open a hole groove at the installation position, and then after the installation base plate 1 corresponds to the hole groove position, the installation base plate 1 is fixed with the expansion bolt 2, and then the submarine cable is passed through the matching leather tube 6 with a smooth cushion layer 8 on the inner side, and then the matching leather tube 6 with the submarine cable inserted will be placed in the placement groove 42 on the arc-shaped installation pad 41. Since a buffer gasket 44 is installed on the side of the arc-shaped installation pad 41, the matching leather tube 6 will be relatively stable. At the same time, the installer will use the reinforcement buckle 43 to bind the matching leather tube 6, so that the submarine cable swings under the impact of seawater, and the metal fasteners 7 at both ends of the matching leather tube 6 will also be deflected with the impact of seawater, which not only protects the appearance of the submarine cable, but also enhances the protection effect. In addition, due to the connection of the reinforcement spring column 33 to the arc-shaped installation pad 41, the reinforcement spring column 33 will also produce a certain elastic deformation, which changes the disadvantage that the existing fixing device cannot be offset, and can better adapt to the environment of submarine wave movement.
