Description

Technical Field

[0001] This utility model relates to the technical field of cable laying, and in particular to a cable anti-settlement mechanism and a wind power terminal tower. Background Technology

[0002] With the continuous growth of global demand for renewable energy, wind power, as a clean and sustainable energy source, has been widely applied and developed. In wind power generation, the electricity generated by wind turbines is typically collected by collector cables to terminal towers, and then transmitted from the terminal towers to substations or grid facilities. In this process, the design and construction quality of the collector cables directly affect the stability and efficiency of the entire wind power system.

[0003] Traditional methods of cable mounting on towers mainly rely on rigid fixation, that is, cable brackets are used to fix the vertical section of the cable to the terminal tower, while the cable is usually buried directly underground in other parts (such as the horizontal section below the terminal tower) for economic reasons.

[0004] In practical applications, it has been found that although the above-mentioned cable installation method is simple and direct, when the cable sinks due to its own weight or when the laying area encounters other external forces such as backfill soil settlement, the vertical section is rigidly fixed to the support, making it unable to adapt to the settlement deformation by making corresponding displacement changes. This can easily lead to problems such as the cable sheath being torn and the insulation layer being damaged. In severe cases, it may even break the cable core wire, causing power transmission failure and affecting the safety and stability of power supply. Utility Model Content

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] To better understand the cable anti-settlement mechanism and wind power terminal tower provided by this utility model, we will first introduce its application background. In wind power generation, the electricity generated by the wind turbine is usually collected by the collector cable to the terminal tower and then transmitted from the terminal tower to the substation or power grid facilities.

[0033] Traditional methods of cable mounting on towers mainly rely on rigid fixation, that is, cable brackets are used to fix the vertical section of the cable to the terminal tower, while the cable in other parts, such as the horizontal section below the terminal tower, is usually buried directly underground due to the simpler line structure and shorter length, and for economic reasons.

[0034] In practical applications, it has been found that although the above-mentioned cable installation method is simple and direct, when the cable sinks due to its own weight or when the laying area encounters other external forces such as backfill soil settlement, the vertical section is rigidly fixed to the support, making it unable to adapt to the settlement deformation by making corresponding displacement changes. This can easily lead to problems such as the cable sheath being torn and the insulation layer being damaged. In severe cases, it may even break the cable core wire, causing power transmission failure and affecting the safety and stability of power supply.

[0035] To address the aforementioned problems, this utility model provides a cable anti-settlement mechanism and a wind power terminal tower, which can effectively reduce cable damage caused by subsidence and ensure the safety and stability of power supply.

[0036] The following is combined with Figures 1-5 This invention describes the cable anti-settlement mechanism and wind power terminal tower.

[0037] Reference Figures 1 to 3 A cable anti-settlement mechanism is disclosed, applicable to cable 10. Cable 10 includes a first part 11 and a second part 12, wherein the first part 11 is suitable for connection with a wind power terminal tower, and the second part 12 is suitable for burial underground. The cable anti-settlement mechanism includes a support structure 20, which is suitable for burial underground and has a support body arranged along the extension direction of the second part 12 of cable 10, with the second part 12 supported on the support body.

[0038] In actual installation of cable 10, the support structure 20 is supported at the bottom of the pre-buried trench, and the second part 12 of cable 10 is laid on the support body of the support structure 20. Under the action of the support structure 20, the sinking problem caused by the weight of the second part 12 is effectively prevented. When the cable 10 laying area encounters other external forces such as backfill soil settlement, the support structure 20 can provide support for the second part 12, preventing the second part 12 from settling with the soil. This ensures that the first part 11 of cable 10 is not subjected to mechanical pulling force caused by settlement deformation, effectively avoiding the problem of cable 10 being damaged, and ensuring the safety and stability of power supply.

[0039] In some optional embodiments, the specific material, shape, and size specifications of the support structure 20 can be configured in combination with the actual construction scenario and economic benefits. For example, the support structure 20 can be made of metal materials such as steel, or non-metallic materials such as rigid plastic. In addition, the support body of the support structure 20 can be set as an integral structure or a split structure according to actual needs, as long as it meets the required support requirements.

[0040] In one embodiment of this utility model, the support structure 20 includes at least two support frames 21 arranged at intervals. Each support frame 21 includes a support portion 210. The support portions 210 on different support frames 21 are positioned correspondingly in the extension direction of the second part 12, thereby forming the aforementioned support body. In practical applications, the support portions 210 of multiple support frames 21 are arranged in the extension direction of the second part 12 to form a support body, thereby providing effective support for the second part 12. Compared with a support structure 20 having an integral support body arranged along the second direction, the aforementioned support structure 20 can effectively reduce manufacturing costs and processing difficulty.

[0041] In some alternative embodiments, the specific structure of the support frame 21 can be designed according to actual needs.

[0042] As a specific embodiment of this utility model, the support frame 21 further includes two spaced-apart legs 211, with both ends of the support portion 210 fixedly connected to the two legs 211 respectively, making the support frame 21 as a whole "H" shape. The "H"-shaped support frame 21 allows the cable 10 to be positioned on the support portion 210 between the two legs 211, improving the stability and convenience of cable 10 laying.

[0043] In some optional embodiments, the various components in the support frame 21 can be fixed by welding, and the support frame 21 as a whole can also be integrally formed. The specific choice can be made according to actual needs, and no specific limitation is made in this embodiment of the utility model.

[0044] In order to improve the overall structural strength and stability of the support structure 20, in one embodiment of the present invention, the support structure 20 further includes a connecting part 22, and adjacent support frames 21 are connected into a whole through the connecting part 22.

[0045] Specifically, the two ends of the connecting part 22 are fixedly connected to the support legs 211 at the corresponding positions of the adjacent support frame 21.

[0046] Alternatively, the connecting part 22 and the support leg 211 of the support frame 21 can be fixed by welding or integral molding. The specific choice can be made according to actual needs, and no specific limitation is made in this embodiment of the utility model.

[0047] In one embodiment of this utility model, an isolation layer 23 is provided between the support 210 and the cable 10 to reduce the wear of the cable 10 on the support 210, thereby further ensuring the safety and stability of power supply.

[0048] As an optional embodiment, the isolation layer 23 can be made of a flexible material. The flexible isolation layer 23 can increase the coefficient of friction between the cable 10 and the support 210, making it less likely for the cable 10 and the support 210 to move relative to each other, thereby reducing wear. It also facilitates the positioning of the cable 10 during the initial laying. On the other hand, it can also isolate the cable 10 from the support 210, effectively preventing wear of the cable 10 caused by mutual friction between the cable 10 and the support 210.

[0049] As another optional embodiment, the insulating layer 23 can also be made of a rigid plastic material with lower strength than metal, thereby reducing wear on the cable 10.

[0050] In some optional embodiments, the specific material of the isolation layer 23 can be selected according to actual needs, such as rubber-based materials, asphalt-based materials, etc., as long as the required coefficient of friction and flexibility requirements are met.

[0051] As a specific embodiment of the present invention, the isolation layer 23 is made of rubber strip, which is wrapped around the outer peripheral surface of the support portion 210 to form the isolation layer 23 described above.

[0052] In one embodiment of this utility model, the second part 12 is fixedly connected to the support part 210 by a connector. The connector can fix the second part 12 to the support part 210, preventing the cable 10 from sliding off the support structure 20 on the support part 210, and ensuring that the support structure 20 can provide effective support for the cable 10.

[0053] The specific structural form of the connector can be selected according to actual needs; for example, clamps or cable ties can be used.

[0054] Taking into account both economic benefits and ease of connection, in one specific embodiment of this utility model, the connector is a binding strap, such as a nylon strap, and the cable 10 and the support 210 are bound and fixed by the binding strap.

[0055] In practical applications, during operation, the current passing through the cable 10 generates heat, causing its temperature to change and resulting in thermal expansion and contraction. Since the first part 11 of the cable 10 is rigidly fixed to the wind power terminal tower, the cable 10 cannot freely extend or contract when it needs to expand or contract due to temperature changes. The stress generated by thermal expansion and contraction will accumulate inside the cable 10, which will also damage the outer sheath, insulation layer, and internal core wires of the cable 10. In the long run, this may lead to cable 10 failure, increasing maintenance costs and repair difficulty.

[0056] In addition, when the cable 10 is subjected to large wind loads, earthquakes or other external forces, the first part 11 of the cable 10 will swing significantly. The rigid fixing point of the first part 11 acts as a fulcrum, causing the cable 10 to collide with the tower or other structures, resulting in wear on the outer sheath of the cable 10 or even damage to the internal core wires, affecting the insulation and conductivity of the cable 10.

[0057] To solve the above problems, in one embodiment of the present invention, the cable anti-settlement mechanism further includes a cable protection pipe 30 sleeved outside the first part 11, which is suitable for fixed connection with the wind power terminal tower.

[0058] This configuration not only enables the connection and fixation of the first part 11 to the wind power terminal tower, but also ensures that the first part 11 of the cable 10 is not bound by a rigid fixing point. When the temperature of the cable 10 changes, it can freely expand or contract, effectively avoiding the stress caused by thermal expansion and contraction that could damage the cable 10. In addition, when the cable 10 is subjected to external forces such as wind loads, the cable protection pipe 30 can provide protection for the first part 11, effectively preventing friction and collision between the cable 10 and external structures, reducing wear on the cable 10, and further ensuring the safety and stability of power supply.

[0059] In some optional embodiments, the specific material and size specifications of the cable protection pipe 30 can be flexibly selected according to the actual construction scenario, and no specific restrictions are imposed in this embodiment of the utility model.

[0060] In one embodiment of this utility model, the openings at both ends of the cable protection tube 30 gradually widen into a trumpet shape.

[0061] In one embodiment of this utility model, the bottom end of the cable protection pipe 30 extends underground.

[0062] It is understood that, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of the different embodiments or examples.

[0063] The wind power terminal tower provided by this utility model is described below. The wind power terminal tower described below and the cable anti-settlement mechanism described above can be referred to in correspondence.

[0064] Reference Figure 4 and Figure 5 A wind power terminal tower includes a tower body 40, a cable 10, and a cable anti-settlement mechanism provided in any of the above embodiments; the first part 11 of the cable 10 is connected to the tower body 40.

[0065] In one embodiment of this utility model, the cable protection pipe 30 is connected to the tower body 40 through multiple cable clamps 41, thereby realizing the connection between the first part 11 and the tower body 40.

[0066] The cable anti-settlement mechanism and wind power terminal tower provided by this utility model embodiment allow the support structure 20 to be supported at the bottom of the pre-buried trench when the cable 10 is installed. The second part 12 of the cable 10 is laid on the support body of the support structure 20. Under the action of the support structure 20, the sinking problem caused by the weight of the second part 12 is effectively prevented. When the cable 10 laying area encounters other external forces such as backfill soil settlement, the support structure 20 can provide support for the second part 12, preventing the second part 12 from settling with the soil. This ensures that the first part 11 of the cable 10 is not subjected to mechanical pulling force caused by settlement deformation, effectively avoiding the problem of cable 10 damage and ensuring the safety and stability of power supply.

[0067] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
