Description

Technical Field

[0001] This utility model belongs to the field of wind power generation technology, and in particular relates to a cable anti-sway device inside the tower of an offshore wind turbine. Background Technology

[0002] With the increasing global demand for clean energy, offshore wind power, as a highly efficient and stable form of renewable energy, has experienced rapid development. Offshore wind turbines typically operate in harsh marine environments, and their towers contain a large number of cables used for power transmission, signal control, and monitoring. These cables are the "lifeline" of the wind turbine, and their reliability and safety directly affect the stability of the entire wind turbine system. Due to the complex marine environment, wind turbines are constantly subjected to alternating loads from wind, waves, and currents, causing continuous and unpredictable vibrations and swaying of the tower. Under this continuous swaying, the cable bundles inside the tower are prone to collisions and friction with the tower wall or other cables. Over time, this can lead to problems such as cable insulation wear, core breakage, and loosening of connection points, posing significant safety hazards. Furthermore, the concentrated arrangement and entanglement of multiple cables not only exacerbates the risk of wear but also greatly complicates subsequent maintenance, troubleshooting, and individual cable replacement. Therefore, it is necessary to provide corresponding cable anti-sway devices. While such devices can provide some stability, they still have significant drawbacks: First, they are mostly integral structures or have fixed apertures, making it impossible to effectively separate multiple cables independently, and interference and wear still exist between the cables; second, the bolt-fastening method is prone to loosening under continuous vibration, and the installation and removal of individual cables is cumbersome, resulting in low maintenance efficiency. Therefore, we provide a cable anti-sway device inside the offshore wind turbine tower to solve the above-mentioned problems. Utility Model Content

[0003] The purpose of this utility model is to provide a cable anti-sway device inside the offshore wind turbine tower. By using a cylinder and multiple sets of cable cylinders in combination, multiple cables are separated, and the abutment plate abuts against the cables, thereby preventing the cables from swaying.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a cable anti-sway device inside an offshore wind turbine tower, comprising a cylinder; the inner wall of the cylinder has multiple T-shaped openings evenly distributed in a ring along the circumference, and a cable spool is provided inside the cylinder corresponding to the position of each T-shaped opening, and the upper and lower ends of each group of cable spools are flush with the upper and lower end faces of the cylinder, and a T-shaped strip inserted into the T-shaped opening is fixed on the surface of each cable spool, and a notch is provided on the inner side of each cable spool away from the surface wall of the cylinder, and an abutment plate is provided inside the notch.

[0005] The present invention is further provided that each movable column is fixed on the outer wall of the spool away from the outer wall of the cylinder, and each movable column has a movable hole that communicates with the inside of the recess. The end face of the movable column away from the spool has a moving hole that communicates with the inside of the movable hole.

[0006] The present invention is further configured such that a pull plate is provided on the end face of the movable column away from the spool, and a movable rod passing through the inside of the moving hole is fixed on the end face of each pull plate.

[0008] The present invention is further configured such that each set of abutment blocks has a screw hole on its end face, and the end face of the movable rod inside the movable hole is fixed with a screw that is screwed in the corresponding screw hole.

[0009] The present invention is further configured such that the diameter of the pull plate is larger than the diameter of the moving hole, the movable rod passes through the inside of the spring, and a locking hole is provided on the cylindrical surface wall between each pair of adjacent sets of spools.

[0010] This utility model has the following beneficial effects: 1.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1 Please see Figures 1 to 6 This utility model is a cable anti-sway device inside an offshore wind turbine tower. By using a cylindrical tube 1 and multiple sets of cable tubes 2 in combination, multiple cables are separated. At the same time, the abutment plate 3 abuts against the cables, thereby preventing the cables from swaying.

[0023] Specifically, the cylinder 1 has multiple T-shaped openings 102 evenly distributed in a ring along its circumference on its inner wall. A spool 2 is provided inside the cylinder 1 at the position corresponding to each T-shaped opening 102, and the upper and lower ends of each group of spools 2 are flush with the upper and lower end faces of the cylinder 1. A T-shaped strip 201 inserted into the T-shaped opening 102 is fixed on the surface of each spool 2. A notch 205 is provided on the inner side of each spool 2 away from the surface wall of the cylinder 1. An abutment plate 3 is provided inside the notch 205. The diameter of the pull plate 301 is larger than the diameter of the moving hole 204. The movable rod 303 passes through the inside of the spring 302. A locking hole 101 is provided on the surface wall of the cylinder 1 between each pair of adjacent groups of spools 2.

[0024] The operation process of this embodiment is as follows: When it is necessary to locate the cable inside the offshore wind turbine tower, the cylinder 1 is installed in the tower, so that multiple sets of cable drums 2 are in the tower together. At this time, the cable is passed through the corresponding cable drum 2. The cable is separated by multiple sets of cable drums 2, so that the multiple cables will not interfere with each other and can be quickly distinguished. The cable can be found immediately. After the cable passes through the inside of the cable drum 2, the abutment plate 3 in the notch 205 is released, so that the abutment plate 3 will move out of the notch 205 and hold the cable inside the cable drum 2, so that the cable will not shake in the cable drum 2. At the same time, the T-shaped strip 201 is inserted into the corresponding T-shaped opening 102, so that the cable drum 2 can be installed on the inner wall of the cylinder 1.

[0025] Example 2 Please see Figure 4 and Figure 5 Based on Embodiment 1, the pull plate 301 and the moving rod are used in combination to make it easier to control the movement of the abutment plate 3.

[0026] Specifically, movable columns 202 are fixed at positions on the outer wall of the spool 2 away from the outer wall of the cylinder 1. Each movable column 202 has an internal movable hole 203 that communicates with the interior of the recess 205. The end face of the movable column 202 away from the spool 2 has a moving hole 204 that communicates with the interior of the movable hole 203. Each end face of the movable column 202 away from the spool 2 is equipped with a pull plate 301. Each pull plate 301 has a fixed end face that passes through the moving hole 204. The movable rod 303 and the abutment plate 3 near the movable hole 203 are both fixed with abutment blocks 305, and the abutment blocks 305 are set in the movable hole 203. The end face of the abutment blocks 305 is fixed with a spring 302 that abuts against the inner end face of the movable hole 203. The end face of each set of abutment blocks 305 is provided with a screw hole 306. The end face of the movable rod 303 inside the movable hole 203 is fixed with a screw 304 that is screwed in the corresponding screw hole 306.

[0027] The operation process of this embodiment is as follows: With the above-described structure, when the cable needs to be passed through the coil 2, the abutment plate 3 needs to be moved into the recess 205. At this time, the pull plate 301 can be controlled to move away from the movable column 202. The pull plate 301 will then drive the movable rod 303 to slide outward in the moving hole 204. The movable rod 303 will then directly drive the abutment plate 3 into the recess 205. At this time, the abutment plate 3 will compress the spring 302, thus allowing the cable to pass through. The cable passes through the inside of the spool 2. When the pull plate 301 is released, the spring 302 will directly push the abutment block 305 to move, and the abutment plate 3 will move out of the recess 205. Thus, the abutment plate 3 holds the cable in place. When it is necessary to remove the abutment plate 3 from the spool 2, the abutment plate 3 can be kept stationary while the pull plate 301 is rotated. This will control the screw 304 to turn out of the screw hole 306, thereby disassembling the movable rod 303 and the abutment plate 3. The abutment plate 3 can then be removed from the spool 2 for replacement.
