Description

Technical Field

[0001] The utility model relates to the technical field of electric power transportation, in particular to a submarine cable fixing bracket. Background Art

[0002] After the submarine cable for offshore wind power is laid from the seabed to the wind turbine foundation platform, it extends from the wind turbine foundation platform through the tower wall hole on the outer wall of the tower into the tower. Due to the heavy weight of the submarine cable, it is easy for the submarine cable to be naturally suspended in the air. When the suspended length of the submarine cable is too long, it will be affected by the natural vibration during operation, the long-term erosion of ocean currents, and the impact of the pile foundation cage by the operation and maintenance ships, which will aggravate the continuous reciprocating friction between the submarine cable and the tower wall hole, causing damage to the submarine cable, and eventually cause electrical failure, causing the wind turbine to shut down.

[0003] Upon investigation, it was found that the Chinese utility model patent with publication number CN219843365U discloses a submarine cable supporting and fixing device, including two brackets, a support plate and a plurality of fixing holes; the two brackets are suitable for being fixed on the base platform of the wind turbine tower, and are arranged at intervals and adjacent to the tower wall holes of the tower; the support plate is connected to the top of the two brackets and is located on the side of the tower, and the height of the support plate is greater than or equal to the height of the tower wall holes of the tower, suitable for supporting the submarine cable; a plurality of fixing holes are arranged on the support plate, suitable for fixing the submarine cable through connecting parts.

[0004] The above-mentioned submarine cable supporting and fixing device reduces the wear on the surface of the submarine cable and improves the reliability of the power collection line by supporting and fixing the suspended submarine cable. However, the device only fixes the submarine cable on the top of the support frame, and the rest of the submarine cable hangs down naturally and is still affected by the natural environment such as sea breeze, and is easily shaken and damaged.

[0005] Therefore, the utility model provides a submarine cable fixing bracket to solve the above problems. Utility Model Content

[0006] 1. Technical issues to be resolved

[0007] The utility model provides a submarine cable fixing bracket, aiming to solve the problems in the prior art that the submarine cable of the existing fixing device hangs down naturally, is still affected by the natural environment such as sea breeze, shakes randomly, and is easily damaged.

[0008] (II) Technical solution

[0009] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a submarine cable fixing bracket, comprising an inner support frame arranged on a base platform and an outer support frame arranged on a side of the inner support frame away from the wind turbine tower, the inner support frame comprising two inner support rods symmetrically arranged on the base platform and a fixing block fixedly connected to the top ends of the two inner support rods, the fixing block being provided with a hole for the submarine cable to pass through, the outer support frame comprising two outer support rods symmetrically arranged on the base platform, a top rod fixedly connected to the top ends of the two outer support rods, and a plurality of fixing blocks arranged between the outer support rods and distributed in a linear array for binding the submarine cable through fasteners. Several fixing rods are arranged on the longitudinal part of the submarine cable, and oblique rods for binding the corner part of the submarine cable through fasteners are fixedly connected at the positions on both sides of the hole corresponding to the fixing block and the top rod. When in use, the fixing block holds the submarine cable so that the submarine cable does not contact the outer wall of the wind turbine tower. At the same time, the hole on the fixing block is flush with the hole on the tower wall, which can avoid the friction of the submarine cable on the hole wall. Flexible protective covers such as rubber can be provided on the inner wall of the hole on the fixing block. Fixing the submarine cable on the oblique rod can make the turning part of the submarine cable more stable. After the submarine cable extending out of the hole in the wind turbine tower wall passes through the hole, it is fixed on the fixing rod to prevent the rest of the cable from shaking at will. The fixing rod is arranged on the outer support rod according to the actual situation.

[0010] Preferably, the inner support rod and the outer support rod are both angle steels, which are lighter in weight while ensuring firmness, and are convenient for transportation and installation.

[0011] Preferably, the height of the outer support frame is lower than that of the inner support frame, and the height difference can be used to tilt the inclined rod to a suitable angle so that the position of the inclined rod for fixing the submarine cable is at the bend of the submarine cable.

[0012] Preferably, a plurality of wind holes are provided on the outer support rod, and the outer support frame away from the wind turbine tower is exposed to stronger sea breeze. The wind holes facilitate air flow and can reduce the force of the sea breeze on the outer support frame.

[0013] Preferably, the distance between the inner support rods, the distance between the outer support rods, and the distance between the inner support frame and the outer support frame gradually decrease from bottom to top, and at least one pair of connecting rods are fixedly connected between the inner support rods and the outer support rods. The inner support rods and the outer support rods are inclined close to each other and connected together, so that the fixed bracket as a whole can be more stable.

[0014] (III) Beneficial effects

[0015] The device fixes the submarine cable extending out of the wall hole of the wind turbine tower by setting a fixing rod to prevent the submarine cable from being affected by natural environment such as sea breeze and being damaged by random shaking, friction or collision.
