Description

Technical Field

[0001] The utility model relates to the technical field of submarine cable installation, in particular to a restraining device for submarine cable installation. Background Art

[0002] As a new type of energy, wind power is gradually extending from land to ocean, and offshore wind power generation is becoming a focus of development in the field of new energy. Because it is located in the sea area with a relatively complex environment, the collection lines in the wind farm use submarine cable lines. The safe operation of the submarine cable directly affects whether the wind farm can operate normally.

[0003] In the process of laying submarine cables, especially the installation and fixation of the submarine cables, the installation method is mostly to install them through brackets, but the existing brackets have a simple structure and cannot achieve fixed installation of the submarine cables. Therefore, we propose a restraining device for submarine cable installation to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 In the utility model, a restraining device for installing a submarine cable includes a circular base 2, a support plate 5, two lower clamps 12 and two groups of first bolts 13. Two groups of first mounting holes 16 are opened on the upper surface of the support plate 5, and four second mounting holes 17 are opened on the bottom surface of each lower clamp 12. The bottom end of each first bolt 13 passes through the second mounting hole 17 and the first mounting hole 16 and extends to the bottom of the support plate 5. The bottom end of each first bolt 13 is threadedly connected to two first nuts 4. A lower fixing block 11 is fixedly installed on the outer surface of each lower clamp 12, and an upper clamp 7 is hinged to the outer surface of each lower clamp 12 through a hinge, and an upper fixing block 6 is fixedly installed on the outer surface of each upper clamp 7.

[0021] Two third mounting holes 18 are provided on the upper surface of each upper fixing block 6, and two fourth mounting holes 19 are provided on the bottom surface of each lower fixing block 11. Two second bolts 10 are provided on the outside of each upper fixing block 6. By providing two third mounting holes 18 on the upper surface of each upper fixing block 6 and two third mounting holes 18 on the bottom surface of each lower fixing block 11, it is convenient to subsequently firmly assemble the upper clamp 7 and the lower clamp 12 together, so as to achieve the binding of the submarine cable. The bottom end of each second bolt 10 passes through the third mounting hole 18 and the fourth mounting hole 19 and extends to the bottom of the lower fixing block 11. The bottom end of each second bolt 10 is threadedly connected with two second nuts 20. By passing the bottom end of each second bolt 10 through the third mounting hole 18 and the fourth mounting hole 19, and bolting the second nut 20 at the bottom end of each second bolt 10, the upper clamp 7 and the lower clamp 12 can firmly bind the submarine cable.

[0022] A lower rubber pad 8 is fixedly installed on the inner wall of each lower clamp 12, and an upper rubber pad 9 is fixedly installed on the inner wall of each upper clamp 7. By installing the lower rubber pad 8 on the inner wall of the lower clamp 12 and installing the upper rubber pad 9 on the inner wall of each upper clamp 7, it is possible to effectively prevent the inner wall of the upper clamp 7 and the inner wall of the lower clamp 12 from rubbing against the outer surface of the submarine cable to cause damage, thereby ensuring the service life of the submarine cable. The upper rubber pad 9 and the lower rubber pad 8 can increase the friction with the outer surface of the submarine cable, making it less likely for the submarine cable to slide. Three fixing pins 1 are fixedly installed on the bottom surface of the circular base 2, and a bearing 15 is fixedly inlaid on the upper surface of the circular base 2. A support column 14 is fixedly installed on the inner ring of the bearing 15. The upper surface of the support column 14 is fixedly installed on the bottom surface of the support plate 5. By installing three fixing pins 1 on the bottom surface of the circular base 2, construction workers can use equipment to firmly install the device on the seabed. By embedding bearings 15 on the upper surface of the circular base 2 and fixing the bottom end of the support column 14 to the inner ring of the bearing 15, the support column 14 can drive the support plate 5 above it to rotate, so that it is convenient to adjust its installation angle when installing the submarine cable. Two reinforcing diagonal rods 3 are fixedly installed on the outer surface of the support column 14, and the top of each reinforcing diagonal rod 3 is fixedly installed on the bottom surface of the support plate 5. By installing two reinforcing diagonal rods 3 on the outer surface of the support column 14, and fixing the top of each reinforcing diagonal rod 3 to the bottom surface of the support plate 5, the support plate 5 can be firmly installed above the support column 14.

[0023] The working principle of the utility model is:

[0024] First, the staff places the submarine cable inside the lower clamp 12 and makes the outer surface of the submarine cable contact with the outer surface of the lower rubber pad 8. Then the staff flips the upper clamp 7 and makes the outer surface of the upper rubber pad 9 contact with the outer surface of the submarine cable. Then the staff sequentially passes the bottom end of the second bolt 10 through the third mounting hole 18 and the fourth mounting hole 19 and threadedly connects them with the two second nuts 20. Then the staff sequentially passes the bottom end of the first bolt 13 through the second mounting hole 17 and the first mounting hole 16 and threadedly connects them with the two first nuts 4.
