Description

Technical Field

[0001] This utility model relates to the field of transmission cable technology, and in particular to a wind power anti-torsion data transmission cable. Background Technology

[0002] Wind energy is the most commercially valuable clean energy source globally and a crucial player in the future renewable energy landscape. Wind power generation is currently the fastest-growing, most mature, and most promising renewable energy source for large-scale development and commercialization. Compared to coal and hydropower, doubling wind power capacity reduces costs by 15%, demonstrating a significant advantage. Furthermore, wind power plays a vital role in adjusting energy structures, mitigating environmental pollution, and achieving sustainable development.

[0003] Chinese utility model patent with publication number CN222106308U discloses a wind power anti-torsion data transmission cable, including a central reinforcement, several conductors, an inner sheath, and an outer sheath; the several conductors are twisted together and surround the central reinforcement, and the outer side of the conductors is covered with an insulating layer; the inner sheath is wrapped around the outer side of the central reinforcement and the conductors, and has good tensile and torsional resistance.

[0004] Regarding the aforementioned technologies, the inventors believe that the following drawbacks exist: the conductors of the aforementioned devices are twisted together, resulting in a longer conductor length. The increased signal transmission path directly leads to increased transmission loss and delay, significantly affecting the stability and efficiency of data transmission. Furthermore, the conductors are typically made of expensive metals such as copper and silver. For the same cable length, the twisted structure significantly increases the amount of conductor used, leading to a substantial increase in raw material costs and manufacturing costs. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a wind power anti-torsion data transmission cable.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a wind power anti-torsion data transmission cable, including a central steel wire rope, a connecting tube sleeved on the central steel wire rope, a plurality of partitions spaced circumferentially on the connecting tube, a transmission wire between two adjacent partitions, an inner tube shared by the partitions on the side away from the connecting tube, a plurality of first steel wire ropes spirally wound on the outer wall of the inner tube, a separator tube shared by the outer sides of the plurality of first steel wire ropes, a plurality of second steel wire ropes spirally wound on the outer wall of the separator tube, the second steel wire ropes having the opposite spiral direction to the first steel wire ropes, and an outer tube shared by the outer sides of the plurality of second steel wire ropes.

[0007] By adopting the above technical solution, which includes a central steel wire rope, transmission wires, a first steel wire rope, and a second steel wire rope, when the cable twists, the first or second steel wire rope will be slightly stretched or compressed. Through its own elastic deformation, it absorbs the torque and prevents the cable from twisting. Several first steel wire ropes resist twisting in one direction, and second steel wire ropes resist twisting in another direction. Regardless of the direction of the external torque, they can cancel each other out through the bidirectional structure, further improving the anti-torsion performance. The central steel wire rope, connecting pipe, and partition enhance the tensile strength of the cable, and the partition separates the transmission wires, ensuring the stability of their respective signal transmissions. While ensuring anti-torsion and tensile performance, the length of the transmission wire is consistent with the length of the cable, ensuring stable and efficient data transmission while reducing manufacturing costs.

[0008] Furthermore, the outer tube is fixedly fitted with several fixing rings arranged at intervals along its length.

[0009] By adopting the above technical solution, a fixing ring is set and a fixing tube is fixedly sleeved on the outer tube to limit the deformation of the first wire rope and the second wire rope, thereby further improving the anti-torsion performance.

[0010] Furthermore, a rubber ring is provided on the inner wall of the fixing ring, and the inner wall of the rubber ring abuts against the outer wall of the outer tube.

[0011] Furthermore, the outer wall of the outer tube is extruded with a protective sleeve, which covers several fixing rings inside.

[0012] By adopting the above technical solution and setting a protective sleeve, the outer tube and fixing ring are protected as a whole.

[0013] Furthermore, the partition plate is provided with mounting holes arranged along its length, and a reinforcing plate is provided in the mounting holes.

[0014] By adopting the above technical solution, mounting holes and reinforcing plates are set. The reinforcing plates enhance the structural strength of the partition and improve the overall tensile strength.

[0015] Furthermore, the transmission wire is covered with an insulating layer on the outside.

[0016] Furthermore, filler ropes are provided on both sides of the transmission wire, and the outer wall of the filler ropes is in contact with the plate surface of the partition, the outer wall of the insulation layer, and the inner wall of the inner tube.

[0017] By adopting the above technical solution, a filler rope is set up to fill the gap between the transmission conductor and the partition and inner tube, ensuring the uniformity of the internal structure of the cable and improving the tensile strength of the cable.

[0018] In summary, this utility model has the following beneficial effects: In this application, a central steel wire rope, transmission wires, a first steel wire rope, and a second steel wire rope are provided. When the cable twists, the first or second steel wire rope will be slightly stretched or compressed, absorbing torque through its own elastic deformation, thus preventing cable twisting. Several first steel wire ropes resist twisting in one direction, and the second steel wire ropes resist twisting in another direction. Regardless of the direction of the external torque, they can cancel each other out through the bidirectional structure, further improving the anti-torsion performance. The central steel wire rope, connecting pipe, and partition enhance the tensile strength of the cable, and the partition separates each transmission wire, ensuring the stability of their respective signal transmission. While ensuring anti-torsion and tensile performance, the length of the transmission wire is consistent with the length of the cable, ensuring stable and efficient data transmission while reducing manufacturing costs.

Detailed Implementation

[0023] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0024] like Figure 1-3As shown in the embodiment of this application, a wind power anti-torsion data transmission cable is disclosed, including a central steel wire rope 10, a transmission conductor 30, a first steel wire rope 41, and a second steel wire rope 51. A connecting pipe 11 is fixedly sleeved on the central steel wire rope 10. Several partitions 20 are arranged circumferentially on the connecting pipe 11, and a transmission conductor 30 is arranged between two adjacent partitions 20. The transmission conductor 30 is used to transmit wind power generation data. The central steel wire rope 10, the connecting pipe 11, and the partitions 20 improve the tensile strength of the cable, and the partitions 20 separate the transmission conductors 30 to ensure the stability of their respective signal transmissions. Several partitions 20 are provided with an inner tube 40 on the side away from the connecting pipe 11. Several first steel wire ropes 41 are spirally wound on the outer wall of the inner tube 40. A partition tube 50 is provided on the outer side of several first steel wire ropes 41, and the partition tube 50 covers several first steel wire ropes 41. Several second steel wire ropes 51 are spirally wound on the outer wall of the separator tube 50. The spiral direction of the second steel wire ropes 51 is opposite to that of the first steel wire rope 41. An outer tube 60 is provided on the outside of the several second steel wire ropes 51, covering the several second steel wire ropes 51. When the cable twists, the first steel wire rope 41 or the second steel wire rope 51 will be slightly stretched or compressed, absorbing the torque through its own elastic deformation, thus preventing the cable from twisting. The several first steel wire ropes 41 resist the torsion in one direction, and the second steel wire ropes 51 resist the torsion in another direction. Regardless of the direction of the external torque, they can cancel each other out through the bidirectional structure, further improving the anti-torsion performance. While ensuring the anti-torsion and tensile performance, the length of the transmission conductor 30 is consistent with the length of the cable, ensuring the stability and efficiency of data transmission while reducing manufacturing costs.

[0025] Specifically, the transmission conductor 30 is covered with an insulation layer 31 to protect it and extend its service life. The insulation layer 31 contacts the surface of the partition 20 and the inner wall of the inner tube 40, ensuring the stability of the transmission conductor 30. Filler ropes 32 are provided on both sides of the transmission conductor 30. The outer wall of the filler ropes 32 contacts the surface of the partition 20, the outer wall of the insulation layer 31, and the inner wall of the inner tube 40. The filler ropes 32 fill the gaps between the transmission conductor 30 and the partition 20 and the inner tube 40, ensuring the uniformity of the internal structure of the cable and improving its tensile strength.

[0026] During installation, the partition 20 is provided with mounting holes 21 arranged along its length, and a reinforcing plate 22 is provided in the mounting holes 21. The reinforcing plate 22 enhances the structural strength of the partition 20 and improves the overall tensile strength.

[0027] In the specific configuration, a number of fixing rings 61, spaced apart along the length of the outer tube 60, are fixedly sleeved on the outer tube 60. When the first steel wire rope 41 and the second steel wire rope 51 deform, they compress the outer tube 60, causing deformation. The spaced fixing rings 61 restrict this deformation, thereby limiting the deformation of the first steel wire rope 41 and the second steel wire rope 51 and further improving torsional resistance. A rubber ring 62 is provided on the inner wall of the fixing ring 61, and the inner wall of the rubber ring 62 abuts against the outer wall of the outer tube 60. This not only restricts the deformation of the outer tube 60 but also protects it, preventing the fixing rings 61 from damaging the outer tube 60.

[0028] The outer tube 60 has a protective sleeve 63 formed by extrusion on its outer wall. The protective sleeve 63 covers several fixing rings 61 and protects the outer tube 60 and the fixing rings 61 as a whole.

[0029] The working principle of a wind power anti-torsion data transmission cable in this embodiment is as follows: the central steel wire rope 10, the connecting pipe 11, and the partition plate 20 enhance the tensile strength of the cable. When the cable is twisted, the first steel wire rope 41 or the second steel wire rope 51 will be slightly stretched or compressed, and the torque will be absorbed through its own elastic deformation to prevent the cable from twisting. The length of the transmission conductor 30 is consistent with the length of the cable, which ensures the stability and efficiency of data transmission while reducing manufacturing costs.

[0030] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
