Abstract
Description
Technical Field
[0001] The present disclosure relates to the technical field of wind power generation, and in particular to an upper tower cable anti-wear device for a wind turbine generator set and a wind turbine generator. Background Art
[0002] Wind turbine tower cables typically extend from the inner wall of the tower to the nacelle via a fixed cable tray. After reaching the twisting platform, the cables are suspended and sheathed to the yaw platform, where they are then fixed to the nacelle's generator. During wind turbine operation, when the tower swings or yaws, friction and wear occur between the suspended upper tower cable sheath and the fixed iron ring between the twisting and yaw platforms. As the turbine ages, the sheath, shielding, semi-conducting, and insulating layers of the upper tower cable wear over time, exposing the copper in the upper tower cable to grounding. This can cause arcing, potentially damaging the generator or causing fire. Utility Model Content

Therefore, it cannot be understood as a limitation of the present disclosure. The terms "inside" and "outside" refer to the inside and outside of the corresponding structural contour.
[0026] In addition, it should be noted that the terms used, such as "first" and "second", are used to distinguish one element from another and do not have order or importance. In addition, in the description with reference to the drawings, the same reference numerals in different drawings represent the same elements.
[0027] It should also be noted that, in the description of this disclosure, unless otherwise expressly specified or limited, the terms "disposed," "connected," "connected," and "installed" should be understood broadly. For example, they may refer to fixed connections, detachable connections, or integral connections; and they may refer to direct connections or indirect connections via an intermediary. Those skilled in the art will understand the specific meanings of these terms in this disclosure based on specific circumstances.
[0028] refer to Figures 1 to 4 As shown, the first aspect of the present disclosure provides an upper tower cable anti-wear device 1 for a wind turbine generator set, comprising a main body 10, a limit member 20 and a plurality of partitions 30, wherein the plurality of partitions 30 are arranged at circumferential intervals around the main body 10, and the first end of each partition 30 is connected to the main body 10, and the second end of each partition 30 extends divergently in a direction away from the main body 10, and the second end of each partition 30 is used to abut against the inner wall of the fixed iron ring 200 provided in the tower of the wind turbine generator set, and a partition area 31 is formed between each two adjacent partitions 30, and each partition area 31 is used for the upper tower cable 100 to pass through, and the limit member 20 is used to limit the movement of the upper tower cable 100 in the partition area 31 to avoid contact between the upper tower cable 100 and the fixed iron ring 200.
[0029] Through the above technical solution, a plurality of partitions 30 extending in a divergent shape are connected to the main body 10, and the plurality of partitions 30 are arranged along the circumference of the main body 10 and the other end of each partition 30 is against the inner wall of the fixed iron ring 200 in the tower. On the one hand, the partition 30 can limit the contact and friction between adjacent upper tower cables 100, and on the other hand, the limiter 20 can limit the movement of the upper tower cable 100 in the separation area 31, thereby avoiding the upper tower cable 100 from colliding with or rubbing against the fixed iron ring 200 in the tower during the shaking process, thereby effectively reducing the accident rate caused by wear of the upper tower cable 100.
[0030] In addition, the upper tower cable anti-wear device 1 involved in this solution has the advantages of simple structure and easy assembly, which makes it more convenient for operators to operate.
[0031] It should be noted that the present disclosure does not limit the specific number of the above-mentioned separators 30, and the number of separators 30 corresponding to the actual number of cables on the tower can be set.
[0032] In order to facilitate the flexible setting of the number of separators 30, such as Figures 1 to 2As shown, in one embodiment of the present disclosure, each separator 30 can be detachably connected to the body 10. In this way, the relevant assembler can increase or decrease the number of separators 30 in a detachable manner according to the actual number of upper tower cables to match the actual usage scenario. In addition, when the separator 30 is worn by the upper tower cables, it is also more convenient to remove the separator 30 for replacement.
[0033] Alternatively, in other embodiments provided in the present disclosure, the separator 30 can also be connected to the main body 10 by a non-detachable method such as welding, riveting, etc. The above-mentioned non-detachable connection method can provide better connection strength between the separator 30 and the main body 10, thereby preventing the separator 30 from loosening or falling off.
[0034] In an exemplary embodiment provided by the present disclosure, Figures 1 to 2 As shown, the wind turbine upper tower cable wear prevention device 1 may further include a plurality of fasteners 40. The main body 10 is formed with a plurality of first mounting holes 11, with adjacent first mounting holes 11 spaced apart along the circumferential direction of the main body 10. Each separator 30 is formed with a second mounting hole 32, and the fasteners 40 are locked within the first mounting holes 11 and the second mounting holes 32. When the separator 30 needs to be installed, the fasteners 40 can be passed through and locked into the first mounting holes 11 and the second mounting holes 32 to achieve fixation between the separator 30 and the main body 10. This simple connection method facilitates disassembly.
[0035] Alternatively, in other embodiments provided in the present disclosure, the above-mentioned separator 30 can also be detachably connected to the main body 10 by snapping. Specifically, a card block is formed on one of the main body 10 and the separator 30, and a card slot is formed on the other of the main body 10 and the separator 30. When the number of separators 30 needs to be increased, the separator 30 can be directly snapped onto the main body 10. When the number of separators 30 needs to be reduced, the separator 30 can be detached from the main body 10 by pulling.
[0036] Alternatively, as Figures 1 to 2 As shown, the body 10 is formed into an annular shape, with a through hole 12 formed in the middle of the body 10. A first mounting hole 11 penetrates the body 10 in the radial direction of the body 10. The fastener 40 includes a bolt 41 and a nut 42. The bolt 41 is inserted into the first mounting hole 11 and the second mounting hole 32, and the nut 42 is locked on the bolt 41 and located in the through hole 12. Because the first mounting hole 11 penetrates the body 10 in the radial direction of the body 10, the through hole 12 formed in the middle of the body 10 can provide an operating space for removing the nut 42 during the assembly and disassembly of the separator 30 and the body 10, thereby facilitating the assembly and disassembly of the separator 30.
[0037] In order to further facilitate the installation of the above-mentioned separator 30, in an exemplary embodiment provided by the present disclosure, as shown in FIG. Figures 1 to 2 As shown, the separator 30 is formed in a rod shape. A second mounting hole 32 is formed at one end of the separator 30 near the body 10. The fastener 40 is partially inserted into and locked in the second mounting hole 32. When installing the separator 30, the rod-shaped separator 30 is more convenient for the operator to hold and apply force. The operator can screw the separator 30 so that the portion protruding from the separator 30 is screwed into the first mounting hole 11 on the body 10. In this case, the first mounting hole 11 can be formed as a threaded hole, and the fastener 40 can be a screw.
[0038] Alternatively, in other embodiments provided in the present disclosure, the above-mentioned separator 30 can also be formed into a plate shape or a block shape, and the present disclosure does not limit this. In short, as long as it can achieve the separation function of the upper tower cables.
[0039] Alternatively, as Figures 1 to 4 As shown, the main body 10 is further formed with a plurality of limiting holes 13, and the limiting members 20 are disposed within the limiting holes 13 and sleeved on the outer circumference of the upper tower cable 100. Thus, the limiting members 20 can be connected to the main body 10 through the limiting holes 13, thereby achieving relative fixation between the upper tower cable 100 and the main body 10. Furthermore, the separator 30 connected to the main body 10 abuts against the fixing iron ring 200, thereby achieving relative fixation between the upper tower cable 100 and the fixing iron ring 200, thereby preventing contact between the upper tower cable 100 and the fixing iron ring 200.
[0040] Alternatively, the limiting hole 13 may also be formed on the partition 30 , so that when the upper tower cable 100 is positioned on the partition 30 by the limiting member 20 , contact between the upper tower cable 100 and the fixing iron ring 200 can be avoided.
[0041] In an exemplary embodiment provided by the present disclosure, Figures 3 and 4 As shown, the limiting member 20 can be a cable tie, which has the advantages of being easy to obtain and inexpensive to manufacture, and also has insulating properties, which can improve the safety of the upper tower cable 100 during the limiting process.
[0042] Alternatively, in other embodiments provided in the present disclosure, the above-mentioned limiting member 20 can also be a clamp, Velcro or other structures. In short, as long as it can achieve the limiting effect on the upper tower cable 100, the present disclosure will not elaborate on this.
[0043] Optionally, the body 10 and the separator 30 are both made of insulating materials. The body 10 and the separator 30 made of insulating materials can provide insulation, and even if the upper tower cable 100 is damaged, arcing, short circuiting, and other problems are unlikely to occur between the body 10 and the separator 30.
[0044] Furthermore, the material used for the above-mentioned main body 10 and separator 30 can be the same as the material of the outer skin of the upper tower cable 100, thereby further reducing the friction between the main body 10 and separator 30 and the upper tower cable 100, and improving the service life of the upper tower cable 100.
[0045] Alternatively, as Figures 1 to 4 As shown, the body 10 may include a first circular ring 101, a second circular ring 102, and a plurality of reinforcing ribs 103. The inner diameter of the first circular ring 101 is larger than the inner diameter of the second circular ring 102. The first circular ring 101 is sleeved on the outer circumference of the second circular ring 102 and is arranged concentrically with the second circular ring 102. One end of each reinforcing rib 103 is connected to the inner wall of the first circular ring 101, and the other end of each reinforcing rib 103 is connected to the outer wall of the second circular ring 102. On the one hand, the reinforcing ribs 103 provided between the first circular ring 101 and the second circular ring 102 can strengthen the connection strength between the first circular ring 101 and the second circular ring 102. On the other hand, the weight of the body 10 can be greatly reduced, the manufacturing cost of the above-mentioned upper tower cable anti-wear device 1 can be saved, and the assembly operation of the body 10 is also more convenient.
[0046] like Figures 3 and 4 As shown, a second aspect of the present disclosure provides a wind turbine, comprising an upper tower cable 100, a tower, a fixed iron ring 200, and the upper tower cable anti-wear device 1 described above. The fixed iron ring 200 is fixedly disposed within the tower, the upper tower cable anti-wear device 1 is disposed within the fixed iron ring 200, and the upper tower cable 100 is passed through a partition 31 formed between each two adjacent partitions 30. This wind turbine has all the beneficial effects of the upper tower cable anti-wear device 1 described above, which will not be elaborated upon in this disclosure.
[0047] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings. However, the present disclosure is not limited to the specific details of the above embodiments. Within the technical concept of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all fall within the scope of protection of the present disclosure.
[0048] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. To avoid unnecessary repetition, this disclosure will not further explain various possible combinations.
[0049] In addition, the various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
