Description

Technical Field

[0001] The present application relates to the technical field of wind power cables, and more specifically, to a torsion-resistant and tensile-resistant wind power cable. Background Art

[0002] Cable is an electrical energy or signal transmission device, usually composed of several or several groups of wires, and wind power cable is also a kind of cable. Wind power cable, also known as wind power generation cable, must not only meet the performance of ordinary cables, but also have the basic characteristics of softness, frequent torsion, and super vertical tensile resistance.

[0003] According to the search, the Chinese patent with patent number CN217655685U discloses a torsion-resistant cable, which includes a protective layer wrapped around the outside of the main conductor and a sheath outside the protective layer; the inner side wall of the sheath facing the protective layer is provided with circumferentially surrounding teeth, and the side wall of the protective layer facing the sheath is provided with circumferentially surrounding tooth grooves, and the tooth grooves are opposite to the teeth one by one; the teeth are inserted into the respective opposite tooth grooves, and the teeth and the tooth grooves are pressed against each other. This application has the effect of enhancing the torsion resistance of the sheath, ensuring the tightness of the cable structure, and extending the service life of the cable.

[0004] Regarding the above-mentioned related technologies, the applicant believes that the above-mentioned torsion-resistant cable, although it can achieve better torsion resistance, is still an ordinary multi-layer protective sheath structure, but the overall structure is not equipped with corresponding tensile facilities. Its tensile resistance during working use is relatively conventional. When the cable is subjected to large tensile force, it will endanger the cable structure and is prone to deformation. If the cable is damaged, it will greatly affect its subsequent use. For this reason, we propose a torsion-resistant and tensile-resistant wind power cable. Utility Model Content

[0005] In order to solve the above problems, the present application provides a torsion-resistant and tensile-resistant wind power cable, which adopts the following technical solutions:

[0006] A torsion-resistant and tensile-resistant wind power cable comprises a plurality of cable cores and a tensile-resistant module, wherein the tensile-resistant module comprises an armor sleeve arranged outside the plurality of cable cores, the outer sleeve of the armor sleeve is provided with an inner protective sleeve, the outer side of the inner protective sleeve is provided with an outer protective sleeve, a reinforcement component is provided between the outer protective sleeve and the inner protective sleeve, and a filling layer is provided between the armor sleeve and the plurality of cable cores.

[0007] Furthermore, the reinforcement component includes a plurality of first engaging blocks fixedly connected to the inner wall of the outer protective sleeve in an annular shape and at equal distances, and a plurality of second engaging blocks fixedly connected to the outer surface of the inner protective sleeve in an annular shape and at equal distances, and the plurality of first engaging blocks are engaged with the plurality of second engaging blocks.

[0008] By adopting the above technical solution, the first engagement block and the second engagement block are engaged with each other, thereby ensuring the tightness of the cable and enhancing the anti-twisting ability.

[0011] Furthermore, the plurality of first engaging blocks are integrated with the outer protective sleeve, and the plurality of second engaging blocks are integrated with the inner protective sleeve.

[0012] By adopting the above technical solution, the first engaging block and the second engaging block can be prevented from loosening or falling off, and the one-piece molding method can further improve the stability.

[0013] Furthermore, the plurality of reinforcing wires are each formed by twisting a plurality of alloy steel wires.

[0014] By adopting the above technical solution,

[0015] Furthermore, the stretch-resistant module also includes a plurality of annular limiting grooves which are all opened on the inner wall of the inner protective sleeve, and a second limiting ring is movably clamped inside the plurality of annular limiting grooves, and the plurality of second limiting rings are fixedly connected to the outer surface of the armor sleeve.

[0016] By adopting the above technical solution, the inner protective sleeve and the armor sleeve can be limited to prevent the inner protective sleeve from loosening.

[0017] Furthermore, the filling layer is made of aramid yarn, and the plurality of cable cores are arranged in a ring shape and at equal distances inside the filling layer.

[0018] By adopting the above technical solution, the aramid yarn has special properties such as low density, very high tensile modulus, high breaking strength and low breaking elongation, thereby further improving the cable strength.

[0019] Furthermore, the stretch-resistant module also includes a corrosion-resistant coating coated on the outer surface of the outer protective sleeve.

[0020] By adopting the above technical solution, the corrosion resistance of the outer surface of the cable can be improved.

[0021] In summary, this application includes the following beneficial technical effects:

[0022] (1) The present application can enhance the anti-twisting ability of the cable by setting up the reinforcement component, and at the same time strengthen the cable as a whole, improve the overall tensile resistance of the cable, so that when the cable is subjected to a large tensile force, the cable is prevented from being deformed and affecting subsequent use, making the cable more durable;

[0023] (2) The present application provides a reinforcing wire, a first limiting ring, and a second limiting ring of an annular limiting groove.

In addition, by applying the corrosion-resistant coating, the outside of the outer protective sheath can be more corrosion-resistant, making the cable as a whole more durable.

[0035] The following is combined with Figure 1-4 This application is described in further detail.

[0036] See also Figure 1-4 A torsion-resistant and tensile-resistant wind power cable includes multiple cable cores 100 and a tensile-resistant module 200. The tensile-resistant module 200 includes an armored sleeve 210 arranged on the outside of the multiple cable cores 100. The outer sleeve of the armored sleeve 210 is provided with an inner protective sleeve 220. The outer side of the inner protective sleeve 220 is provided with an outer protective sleeve 230. A reinforcement component 240 is provided between the outer protective sleeve 230 and the inner protective sleeve 220. A filling layer 250 is provided between the armored sleeve 210 and the multiple cable cores 100.

[0037] During the use of the present cable, the reinforcement component 240 is provided to enhance the cable's anti-twisting capability, and at the same time, the cable as a whole is strengthened to enhance the cable's overall anti-tensile capability, thereby enhancing the overall strength of the cable.

[0038] The reinforcement component 240 includes a plurality of first engaging blocks 241 fixedly connected to the inner wall of the outer protective sleeve 230 in a ring shape and at equal distances, and a plurality of second engaging blocks 242 are fixedly connected to the outer surface of the inner protective sleeve 220 in a ring shape and at equal distances. The plurality of first engaging blocks 241 are meshed with the plurality of second engaging blocks 242. The reinforcement component 240 also includes a plurality of reinforcing wires 243 fixedly connected to the interior of the plurality of first engaging blocks 241 and the plurality of second engaging blocks 242, respectively.

The plurality of first engaging blocks 241 are integrated with the outer protective sleeve 230, and the plurality of second engaging blocks 242 are integrated with the inner protective sleeve 220. The multiple reinforcing wires 243 are all twisted together from multiple alloy steel wires. The tensile-resistant module 200 also includes a multiple annular limiting grooves 270 that are all opened on the inner wall of the inner protective sleeve 220. The interiors of the multiple annular limiting grooves 270 are all movably clamped with second limiting rings 280, and the multiple second limiting rings 280 are all fixedly connected to the outer surface of the armor sleeve 210.

[0039] Through the engagement of the first engagement block 241 and the second engagement block 242, the outer protective sleeve 230 and the inner protective sleeve 220 are tightened, thereby improving the overall anti-twisting ability. At the same time, through the setting of the reinforcing wire 243, the reinforcing wire 243 is twisted by multiple alloy steel wires, which can provide extremely high tensile strength and excellent wear resistance, thereby strengthening the cable as a whole, improving the overall tensile resistance of the cable, and then improving the overall strength of the cable. The second limiting ring 280 is stuck in the annular limiting groove 270 for further limiting, while preventing the inner protective sleeve 220 from loosening on the outer surface of the armor sleeve 210, so that the cable as a whole is more stable.

The tensile-resistant module 200 further includes a corrosion-resistant coating 260 coated on the outer surface of the outer protective sleeve 230 .

[0041] By setting the filling layer 250 to be made of aramid yarn material, aramid yarn is a high modulus aramid yarn suitable for ADSS optical cables, non-metallic optical cables and indoor optical cables. Aramid yarn has special properties such as low density, very high tensile modulus, high breaking strength and low breaking elongation, thereby further improving the cable strength. By coating with the corrosion-resistant coating 260, the exterior of the outer protective sheath 230 can be more corrosion-resistant, making the cable as a whole more durable.

[0042] The implementation principle of the embodiment of the present application is: during the use of the present cable, through the engagement of the first engagement block 241 and the second engagement block 242, the outer protective sleeve 230 and the inner protective sleeve 220 are tightened, thereby improving the overall anti-torsion ability. At the same time, through the setting of the reinforcing wire 243, the reinforcing wire 243 is twisted by multiple alloy steel wires, has a certain degree of softness, and can provide extremely high tensile strength and excellent wear resistance, thereby strengthening the cable as a whole, improving the overall tensile resistance of the cable, and then improving the overall strength of the cable. The second limiting ring 280 is stuck in the annular limiting groove 270 for further limiting, while preventing the inner protective sleeve 220 from loosening on the outer surface of the armor sleeve 210, so that the cable as a whole is more stable. By setting the filling layer 250 to be made of aramid yarn material, aramid yarn is a high modulus aramid yarn, which is suitable for ADSS optical cables, non-metallic optical cables and indoor optical cables. Aramid yarn has special properties such as low density, very high tensile modulus, high breaking strength and low breaking elongation, which further improves the strength of the cable. By coating with the corrosion-resistant coating 260, the exterior of the outer protective sheath 230 can be more corrosion-resistant, making the cable as a whole more durable.
