Description

Technical Field

[0001] The utility model relates to the field of submarine cable brackets, in particular to a submarine cable bracket. Background Art

[0002] Submarine cables are cables that can be laid on the seabed for communication or power transmission. Compared with other types of cables, most submarine cables are laid on the seabed, do not require supports or tunnels, are constructed faster, and are not affected by human activities or sea waves, making them more stable.

[0003] However, in some special cases, the submarine cable needs to extend from the seabed to the sea surface and connect to water equipment such as wind power generation equipment and offshore work platforms. In this case, it is necessary to use a bracket to support and fix the submarine cable and reduce the impact of wind and waves on the sea surface.

[0004] During the long-term operation of the submarine cable, the bolts on the clamp of a single submarine cable bracket loosen and cannot hold the submarine cable tightly. The shaking caused by wind and waves and the weight of the submarine cable itself cause the Roxet to slip and the submarine cable to be damaged. Utility Model Content

If the submarine cable fixed on the main bracket falls, the sub-bracket can further support the falling submarine cable, thereby improving the supporting effect and preventing the submarine cable from being damaged by external forces, thereby effectively solving the problems in the background technology.

DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] In order to address the shortcomings of the existing technology, such as Figure 1-5 As shown, the utility model provides a submarine cable bracket, including a base 1, a main bracket 2 and a secondary bracket 3 are arranged on the top of the base 1, the main bracket 2 and the secondary bracket 3 have the same structure, the main bracket 2 and the secondary bracket 3 both include a column 5, and the height of the column 5 of the secondary bracket 3 is lower than the height of the column 5 of the main bracket 2;

[0026] A slide seat 4 is provided at the top of the base 1 through a slide rail, a fastening bolt is provided at the top of the slide seat 4 through a thread, a column 5 of the auxiliary bracket 3 is fixed at the top of the slide seat 4, and a column 5 of the main bracket 2 is fixed at the top of the base 1.

[0027] A main bracket 2 and a sub-bracket 3 are arranged at the top of the base 1, and the structures of the two are exactly the same. The only difference is that the height of the sub-bracket 3 is lower than that of the main bracket 2, and the sub-bracket 3 is fixed to the top of the slide 4. The distance between the main bracket 2 and the sub-bracket 3 is adjusted by sliding the slide 4, and the submarine cable is fixed to the main bracket 2 and the sub-bracket 3. If the submarine cable fixed on the main bracket 2 falls, the sub-bracket 3 can further support the falling submarine cable, thereby improving the supporting effect and preventing the submarine cable from being damaged by external force.

[0028] The submarine cable must be fixed tightly and protected from damage. Figure 2 , 3 As shown in FIG. 5 , a sliding sleeve 11 is sleeved on the outer end of the column 5, and a crossbeam 6 is fixedly provided on both sides of the sliding sleeve 11. A plurality of fixing components 8 are provided on the top of the crossbeam 6, and the submarine cable is fixed to the crossbeam 6 through the fixing components 8;

[0029] The fixing assembly 8 comprises an arc-shaped seat 802 , a cover plate 801 is provided at the top of the arc-shaped seat 802 via bolts, and the submarine cable is provided between the cover plate 801 and the arc-shaped seat 802 .

[0030] A second spring 803 and a ball hinge 805 are fixedly disposed at the bottom end of the arc seat 802, and the bottom ends of the second spring 803 and the ball hinge 805 are fixedly connected to the top end of the crossbeam 6;

[0031] Two elastic bands 804 are fixedly provided at the bottom end of the arc-shaped seat 802 , and the bottom ends of the elastic bands 804 are fixedly connected to the crossbeam 6 .

[0032] The submarine cable is clamped between the cover plate 801 and the arc seat 802, and the cover plate 801 and the arc seat 802 are connected by bolts. Anti-slip pads can also be covered on the inner walls of the two to improve the fixing effect. After the submarine cable is fixed, when shaking occurs, the cover plate 801 and the arc seat 802 shake accordingly, and the ball head hinge 805 rotates accordingly, and the second spring 803 bends, so that the elastic force of the second spring 803 is used to buffer the shaking of the submarine cable. If the submarine cable rotates horizontally, the cover plate 801 and the arc seat 802 will also rotate accordingly, and the elastic band 804 will be stretched, so that the horizontal rotation of the submarine cable is buffered by the elastic force of the elastic band 804, thereby reducing the damage to the submarine cable by external force and avoiding damage to the submarine cable.
