[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0028] like Figure 1 - Figure 8 The diagram shows a wind turbine tower power cable with enhanced insulation protection. This wind turbine tower power cable with enhanced insulation protection is equipped with an insulation protection mechanism, a locking assembly, and an external reinforcement assembly. The arrangement of each mechanism and assembly can effectively prevent external thieves from cutting and damaging the insulation sleeve 1, avoid exposing the cable core 14, and significantly improve the safety of insulation protection. The specific structural settings of each mechanism and assembly are as follows.
[0029] In this embodiment, as Figure 1 - Figure 5As shown, the inner wall of the positioning groove ring 2 is provided with an insulating protection mechanism, which includes: a sleeve 3, which slides on the inner wall of the positioning groove ring 2, and a steel wire rope 4 is fixedly connected to one side of the outer wall of the sleeve 3. One end of the steel wire rope 4 is fixedly connected to a pull plate 5; a rotating shaft 6, which is fixedly connected to the bottom end of the pull plate 5. A reduction motor 7 is installed at the bottom end of the rotating shaft 6, which drives the rotating shaft 6 to rotate. The reduction motor 7 is fixedly connected to the positioning groove ring 2; and a sleeve block 8, which slides on the outer wall of the steel wire rope 4. A track 9 is fixedly connected to one side of the sleeve block 8, and an electromagnet 10 is installed inside the sleeve block 8, located on one side of the wire rope 4. A positioning rail 11 slides on the inner wall of the sleeve column 3 and is fixedly connected to the positioning groove ring 2. An insulating baffle 12 is fixedly connected to the bottom end of the sleeve column 3. A locking assembly is located on the top of the pull plate 5 and is used to lock the pull plate 5. An outer reinforcement assembly is located on the outer wall of the insulating baffle 12 and is used to protect the insulating baffle 12. The outer wall of the sleeve column 3 and the inner wall of the positioning groove ring 2 are both smooth surfaces, as are the outer wall of the positioning rail 11 and the inner wall of the sleeve column 3. The cross-sectional shape of the track 9 is arc-shaped, and the electromagnet 10 is used to magnetically attract the sleeve column 3. The center point of the pull plate 5 and the center point of the rotating shaft 6 are on the same vertical line, and the cross-sectional shape of the rotating shaft 6 is circular.
[0030] The geared motor 7 drives the rotating shaft 6 to rotate, which in turn drives the pull plate 5 to rotate. The other end of the wire rope 4 drives the sleeve 3 to move along an arc-shaped path. The sleeve 3 moves along the outer wall of the positioning rail 11 in an arc-shaped path. The insulating baffle 12 moves along the outer wall of the insulating sleeve 1 in an arc-shaped path. The sleeve block 8 supports the rail 9, which enables the sleeve 3 to perform arc-shaped path guiding movement. After the insulating baffle 12 rotates 180 degrees, it can provide insulation and blocking protection in front of the insulating sleeve 1. The electromagnet 10 can then magnetically fix the sleeve 3, ensuring that the insulating baffle 12 is automatically positioned outside the insulating sleeve 1 for insulation protection. This prevents thieves from damaging the outer wall of the insulating sleeve 1 and significantly enhances the insulation protection of the insulating sleeve 1.
[0031] In this embodiment, as Figure 2 As shown, a groove 13 is embedded in the upper surface of the positioning ring 2, and the cross-sectional shape of the groove 13 is arc-shaped. The groove 13 is used to guide the sleeve post 3 to move along the arc-shaped path. Multiple cable cores 14 are installed on the inner wall of the insulating sleeve 1. This allows the sleeve post 3 to move along the arc-shaped path of the groove 13 on the inner wall of the positioning ring 2, and the cable cores 14 are insulated and protected by the outside of the insulating sleeve 1, thus achieving better insulation protection.
[0032] In this embodiment, as Figure 2 - Figure 3As shown, a limiting ring 15 is fixedly connected to the outer wall of the sleeve 3 and to the upper surface of the positioning groove ring 2, and the limiting ring 15 is slidably connected to the positioning groove ring 2; a support frame 16 is fixedly connected to the bottom end of the outer wall of the sleeve block 8, and the support frame 16 is fixedly connected to the positioning groove ring 2; a controller 17 is installed on the upper surface of the positioning groove ring 2 away from the reduction motor 7, and the controller 17 is electrically connected to the reduction motor 7. This allows the sleeve 3 to drive the limiting ring 15 to slide on the upper surface of the positioning groove ring 2, and the limiting ring 15 can perform a limiting sliding operation.
[0033] In this embodiment, as Figure 3 - Figure 6 As shown, the engagement locking assembly includes: a fixed plate 18, fixedly connected to the top of the pull plate 5, with multiple fixed teeth 19 fixedly mounted on its upper surface; multiple pressure teeth 20, located above the fixed teeth 19, arranged in a rectangular equidistant pattern, with a pressure plate 21 mounted on the top of each pressure tooth 20, and all pressure teeth 20 fixedly connected to the pressure plate 21; a connecting block 22, fixedly located on the outer wall of the pressure plate 21, with a retraction rod 23 mounted below the connecting block 22, and a retraction electric cylinder 24 mounted at the bottom of the retraction rod 23, the outer wall of the retraction electric cylinder 24 fixedly connected to the positioning groove ring 2, and the retraction electric cylinder 24 used to move the connecting block 22 downward. A gap is provided between the pressure plate 21 and the fixed plate 18, and the cross-sectional area of the upper surface of the fixed teeth 19 is smaller than the cross-sectional area of its lower surface.
[0034] The retracting end of the retracting cylinder 24 drives the retracting rod 23 to move the connecting block 22 downward, causing the pressure plate 21 to move multiple pressure teeth 20 downward. The multiple pressure teeth 20 press downward onto multiple fixed plates 18 and engage and lock. The multiple pressure teeth 20 also engage and lock with multiple fixed teeth 19, keeping the pulling plate 5 locked and stationary, and keeping the wire rope 4 and the sleeve 3 stationary. This stably achieves the protection of the insulating area outside the insulating baffle 12 and the insulating sleeve 1, resulting in better insulation protection.
[0035] In this embodiment, as Figure 7 - Figure 8 As shown, the peripheral reinforcement components include: a reinforcement plate 29, fixedly connected to the outer wall of the insulating baffle 12, with multiple support columns 25 fixedly connected to the lower surface of the reinforcement plate 29; an arc-shaped outer plate 27, fixed to the outer wall of the support columns 25, with a protective plate 28 fixedly connected to the upper surface of the arc-shaped outer plate 27, and support bars 26 fixedly installed at both ends of the arc-shaped outer plate 27, with the support bars 26 fixedly connected to the reinforcement plate 29. The multiple support columns 25 are arranged in an arc with equal spacing, and the cross-sectional shape of each support column 25 is circular.
[0036] The insulating baffle 12 supports the reinforcing plate 29, ensuring stable support for multiple pillars 25. At the same time, the pillars 25 support the arc-shaped outer plate 27. In this way, the upper surface of the arc-shaped outer plate 27 is reinforced and supported by the protective plate 28, which greatly improves the stability of the insulating baffle 12.
[0037] The working principle of the wind turbine tower power cable with enhanced insulation protection according to this invention is as follows: Step 1: During insulation protection, the positioning ring 2 is fixed by inserting expansion bolts into the holes of the positioning ring 2. The positioning ring 2 supports the insulating sleeve 1, and the insulating sleeve 1 suspends and supports the cable core 14, increasing the stability of the cable core 14.
[0038] The controller 17 drives the geared motor 7, which in turn drives the rotating shaft 6 to rotate. The rotating shaft 6 drives the pull plate 5 to rotate, causing one end of the wire rope 4 to wind up. The wire rope 4 slides along the outer wall of the sleeve block 8, while the other end of the wire rope 4 drives the sleeve post 3 to move along an arc-shaped path. The sleeve post 3 moves along the arc-shaped path of the groove 13 on the inner wall of the positioning groove ring 2 and along the arc-shaped path of the outer wall of the positioning rail 11. The sleeve post 3 also drives the insulating baffle 12 to move along an arc-shaped path along the outer wall of the insulating sleeve 1. At the same time, the positioning groove ring 2 supports the sleeve block 8, and the sleeve block 8 supports the rail 9. The rail 9 allows the sleeve post 3 to perform the arc-shaped path guiding movement operation. Simultaneously, the sleeve post 3 drives the insulating baffle 12 to move along an arc-shaped path. After the insulating baffle 12 rotates 180 degrees, it can provide insulation and protection in front of the insulating sleeve 1. Then, the controller 17 activates the electromagnet 10, which magnetically fixes the sleeve post 3.
[0039] Step 2: During engagement and locking, the controller 17 starts the retraction cylinder 24. The retraction end of the retraction cylinder 24 drives the retraction rod 23, causing the connecting block 22 to move down. The connecting block 22 drives the pressure plate 21 to move down. The pressure plate 21 drives multiple pressure teeth 20 to move down. All the pressure teeth 20 press down and engage and lock on multiple fixed plates 18. The multiple pressure teeth 20 engage and lock with multiple fixed teeth 19, thus keeping the pulling plate 5 locked and stationary. This also keeps the wire rope 4 stationary, the sleeve 3 stationary, and the insulating baffle 12 stationary.
[0040] Step 3: During the external reinforcement, the reinforcing plate 29 is supported by the insulating baffle 12. The reinforcing plate 29 supports multiple pillars 25 and supports the support strips 26. At the same time, the pillars 25 support the arc-shaped outer plate 27. The upper surface of the arc-shaped outer plate 27 is reinforced and supported by the protective plate 28 to increase the stability of the insulating baffle 12.

Electrical control components not mentioned in this technical solution are not shown in the figures because they are existing technologies, and will not be described here.
