[0002] With the development of wind power generation, the supporting wind power cables have also developed rapidly, and the requirements are becoming increasingly stringent. Wind power cables are mainly suspended vertically inside the tower and twist with the wind.

[0003] During use, cables are subjected to gravity, torsional force, and other forces. Continuous gravitational pulling, frequent torsional impacts, and additional forces under extreme weather conditions make cables extremely susceptible to damage, such as outer sheath cracking and core breakage. This not only reduces power transmission efficiency and increases power loss, but also shortens the service life. Utility Model Content

[0004] To overcome the above-mentioned defects, the embodiments of this disclosure provide a wind power generation cable, which solves the technical problems in the prior art where the cable is suspended inside the tower and subjected to continuous gravitational tension and frequent torsional impacts, which easily reduces transmission efficiency, increases power loss, and shortens service life.

[0033] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the scope of the disclosure.

[0034] To keep the drawings concise, each drawing only schematically shows the parts relevant to the disclosure; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of components with the same structure or function is schematically shown, or only one is labeled. In this document, "one" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0035] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linkage" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0036] In this disclosure, unless otherwise expressly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0037] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0038] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0039] like Figures 1-4 As shown, a wind power cable according to an embodiment of this disclosure includes a cable core 1, a fixing frame 2, a reinforcing core 3, a protective mechanism, and a fixing mechanism. The fixing frame 2 is made of rubber, and the reinforcing core 3 is made of a metal material similar to steel wire rope. The fixing frame 2 has a reinforcing hole, and the reinforcing core 3 is fixedly connected to the reinforcing hole. The fixing frame 2 also has a fixing hole, and the cable core 1 is fixedly connected to the fixing hole. The reinforcing core 3 is fixedly connected to the fixing frame 2. Through the cooperation between the fixing frame 2, the reinforcing core 3, the protective mechanism, and the fixing mechanism, the tensile and torsional strength of the cable is increased, and the cable is easily fixed to the inner wall of the tower. This not only reduces the degree of cable damage, but also improves the power transmission efficiency, reduces power loss, increases service life, and improves the stability of the cable during use.

[0040] The protective mechanism is mounted on the fixed frame 2 to protect the cable core 1 while dissipating its heat. The protective mechanism includes a protective layer 4, a spiral frame 5, a heat-conducting plate 6, and a wrapping layer 7. The wrapping layer 7 is made of metal. The spiral frame 5, the protective layer 4, and the wrapping layer 7 form a ventilation channel for external airflow. The spiral frame 5 is made of metal, and its inner ring contacts the protective layer 4. The protective layer 4 is fitted onto the circumferential surface of the fixed frame 2. The spiral frame 5 is fixedly connected to the protective layer 4. The heat-conducting plate 6 is fixedly connected to the spiral frame 5. The wrapping layer 7 is fitted onto the circumferential surfaces of the spiral frame 5 and the heat-conducting plate 6. Specifically, the spiral frame 5 and the heat-conducting plate 6 form a ventilation channel between the protective layer 4 and the wrapping layer 7, dissipating the heat emitted by the cable core 1. When external airflow enters the ventilation channel, it carries the heat from the spiral frame 5 and the heat-conducting plate 6 out of the wrapping layer, thus protecting the cable core 1 while facilitating heat dissipation.

[0041] The fixing mechanism is set on the periphery of the fixing frame 2 and is used to fix the cable core 1 and the fixing frame 2 inside the tower. The fixing mechanism includes a fixing ring 8 and a hanging ring 9. A connecting block 10 is fixedly connected to the fixing ring 8, and the hanging ring 9 is fixedly connected to the top of the connecting block 10. The fixing ring 8 is rotatably connected to the wrapping layer 7, and the hanging ring 9 is fixedly connected to the fixing ring 8. Specifically, the cable is fixed by connecting the fixing ring 8 and the hook and hanging the hook on the inner wall of the tower.

[0042] In this embodiment, the spiral frame 5 is wrapped around the protective layer 4, and the metal wrapping layer 7 on the frame improves the protection of the cable. The spiral frame 5 and the heat-conducting plate 6 are arranged between the protective layer 4 and the wrapping layer 7 to form a ventilation channel. The spiral frame 5 and the heat-conducting plate 6 conduct the heat emitted by the cable core 1. When the external airflow enters the ventilation channel, it carries the heat on the spiral frame 5 and the heat-conducting plate 6 out of the wrapping. While protecting the cable core 1, it is also convenient to dissipate heat from the cable core 1. The cable is fixed by the connection between the fixing ring 8 and the hook, and the hook is hung on the inner wall of the tower.

[0043] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
