Description

Technical Field

[0001] The utility model relates to the technical field of cables, in particular to a torsional resistance cable for a wind turbine generator set. Background Art

[0002] Wind power generation converts the kinetic energy of wind into electrical energy. As a clean and renewable energy source, wind energy is increasingly receiving attention from countries around the world. During the construction of wind turbines, a large number of cables of different specifications need to be laid.

[0003] At present, when using wind turbine cables, there is a lack of auxiliary anti-torsion resistance mechanism. Usually, during the operation of wind turbine cables, they will shake due to the influence of wind in the working environment. This not only easily causes the cable to twist and damage the outer skin, affecting the quality and safety of use, but also affects the maintenance frequency and number of wind turbines. Therefore, a torsional resistance cable for wind turbines is proposed to add an auxiliary anti-torsion resistance mechanism. By means of auxiliary rotation limiting, a certain torsional space is increased at the same time, thereby improving the stability of cable use, making it less susceptible to twisting due to wind in the working environment, and less likely to cause damage to the outer skin, thereby improving the use effect. Utility Model Content

[0004] In response to the problems in the prior art, the utility model provides a torsional resistance cable for a wind turbine generator set, so as to add an auxiliary torsional resistance mechanism. By means of auxiliary rotation limiting, a certain torsional space is added at the same time, thereby improving the stability of cable use and thus improving the use effect.

[0005] The technical solution adopted by the utility model to solve the technical problem is a torsion-resistant cable for a wind turbine generator set, comprising a cable, an anti-torsion component and a splicing component. The outer sheath of the cable is provided with an anti-torsion component, and the outer side of the anti-torsion component is provided with a splicing component.

[0006] The anti-torsion component includes a sheath, a rotating sleeve is rotatably connected inside the sheath, and the rotating sleeve is connected to the cable by gluing. An arc-shaped sliding groove is opened on the inner side of the sheath at the periphery of the rotating sleeve, a fan-shaped slider is slidably connected in the arc-shaped sliding groove, and the fan-shaped slider is fixedly connected to the rotating sleeve by screws.

[0007] By adopting the above technical solution, an auxiliary anti-torsion resistance mechanism can be added, and the stability of the cable operation can be improved by using the rotation limit method, making it less susceptible to torsion caused by the working environment, thereby slowing down the loss rate of the cable sheath.

[0008] Specifically, the splicing assembly includes a U-shaped block and a convex block. One side of the sheath is connected to the U-shaped block by welding, and the other side of the sheath is connected to the convex block by welding. A screw is sleeved inside the U-shaped block.

[0009] By adopting the above technical solution, an auxiliary splicing mechanism can be added, and adjacent cables can be auxiliary spliced and combined by using the plug-in limit method, thereby improving the uniformity and stability of cable use and making it less susceptible to shaking in the working environment.

[0010] Specifically, springs are installed on both sides of the fan-shaped sliding block in the arc-shaped sliding groove through clamping grooves.

[0011] By adopting the above technical solution, it is convenient to utilize elastic thrust to relieve the pressure generated by the torsional resistance of the cable and to assist in limiting it.

[0012] Specifically, both ends of the screw are located outside the U-shaped block and are connected to the threaded sleeve through threads, and the surfaces of the U-shaped block and the protrusion are both provided with through holes corresponding to the screw.

[0013] By adopting the above technical solution, the splicing assembly is subjected to auxiliary limiting processing by utilizing the threaded connection screw, so that the screw can pass through the splicing assembly to perform the auxiliary limiting connection processing.

[0014] Specifically, an elastic pad is connected to the inner surface of the rotating sleeve by gluing, and the elastic pad is made of rubber.

[0015] By adopting the above technical solution, the deformation pressure caused by the torsional resistance of the cable can be further alleviated.

[0016] Beneficial effects of the utility model:

[0017] (1) The utility model discloses a torsion-resistant cable for a wind turbine generator set. The cable is provided with a sheath, a rotating sleeve, an arc-shaped slide groove and a fan-shaped slider, which can increase an auxiliary torsion-resistant mechanism. By limiting the rotation of the cable and increasing a certain amount of activity space, the cable can be provided with an auxiliary limiter. At the same time, the cable's torsion resistance can be improved. The cable is less susceptible to the effects of the working environment and other factors on its quality of use. The cable sheath loss rate is slowed down, and the cable is used more reasonably and stably.

[0018] (2) The torsion-resistant cable for a wind turbine generator set described in the present invention can add an auxiliary splicing mechanism by means of the U-shaped block, protrusion, screw and threaded seat. By means of plug-in and limit combination, the uniformity and stability of the installation between the cables can be improved, thereby reducing the shaking during the operation, making the use more stable and reliable, and having a higher use value.

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] In order to facilitate the addition of auxiliary anti-torsion resistance mechanism, a certain amount of torsion space is added by means of auxiliary rotation limit, thereby improving the stability of cable use and thus improving the use effect, such as Figure 1-3 As shown, the utility model discloses a torsion-resistant cable for a wind turbine generator set, comprising a cable 1, an anti-torsion component 2 and a splicing component 3. The anti-torsion component 2 is sheathed on the outer periphery of the cable 1, and the splicing component 3 is provided on the outer side of the anti-torsion component 2.

[0026] The anti-torsion component 2 includes a sheath 201, a rotating sleeve 202 is rotatably connected inside the sheath 201, and the rotating sleeve 202 is connected to the cable 1 by gluing. An arc-shaped sliding groove 203 is opened on the inner side of the sheath 201 at the periphery of the rotating sleeve 202, and a fan-shaped slider 204 is slidably connected inside the arc-shaped sliding groove 203, and the fan-shaped slider 204 is fixedly connected to the rotating sleeve 202 by screws.

[0027] During use, an auxiliary anti-torsion resistance mechanism can be added through the sheath 201, the rotating sleeve 202, the arc-shaped slide groove 203 and the fan-shaped slider 204. By utilizing the rotation limit method, the working stability of the cable 1 is improved, and it is less susceptible to torsion caused by the working environment, thereby slowing down the loss rate of the cable sheath.

[0028] In order to improve the stability of the cable 1, for example, Figure 1 、 Figure 3 As shown, the present invention also includes that the splicing assembly 3 includes a U-shaped block 301 and a protrusion 302, one side of the sheath 201 is connected to the U-shaped block 301 by welding, and the other side of the sheath 201 is connected to the protrusion 302 by welding, and a screw 303 is sleeved inside the U-shaped block 301.

[0029] During use, an auxiliary splicing mechanism can be added through the U-shaped block 301, the protrusion 302 and the screw 303, and the adjacent cables 1 can be auxiliary spliced and combined by using the plug-in limit method, thereby improving the uniformity and stability of the use of the cable 1 and making it less susceptible to shaking in the working environment.

[0030] For example, Figure 2 As shown, the present invention further includes springs 205 installed on both sides of the fan-shaped slider 204 in the arc-shaped sliding groove 203 through slots.

[0031] When in use, the spring 205 can utilize elastic thrust to relieve the pressure generated by the torsional resistance of the cable 1 and assist in limiting the position thereof.

[0032] For example, Figure 3 As shown, the present invention also includes that both ends of the screw 303 are located on the outside of the U-shaped block 301 and are connected to the threaded sleeve 304 through threads, and the surfaces of the U-shaped block 301 and the protrusion 302 are both provided with through holes 305 corresponding to the screw 303.

[0033] When in use, the threaded sleeve 304 facilitates the use of the threaded connection screw 303 to perform auxiliary limiting processing on the splicing component 3, and the through hole 305 facilitates the screw 303 to penetrate the splicing component 3 to perform auxiliary limiting connection processing.

[0034] For example, Figure 2 As shown, the present invention further includes that the inner surface of the rotating sleeve 202 is connected to an elastic pad 206 by gluing, and the elastic pad 206 is made of rubber.

[0035] During use, the toughness of the elastic pad 206 can further alleviate the deformation pressure caused by the torsional resistance of the cable 1 .

[0036] When the present invention is in use, the operator can first insert the protrusions 302 of the adjacent splicing components 3 into the corresponding U-shaped blocks 301, and then pass the screw 303 through the through hole 305, and the threaded sleeve 304 is threadedly connected to the two ends of the screw 303, and the adjacent cables 1 are auxiliary spliced and combined, which can improve the stability of the cable during installation and use, and is less susceptible to shaking caused by wind. Moreover, in the actual work process, the torsional space range of the cable 1 within a certain range can be increased by rotating the sleeve 202, the arc-shaped slide groove 203 and the fan-shaped slider 204. At the same time, the elastic force of the spring 205 is used to avoid excessive torsion, thereby slowing down the speed of the torsional resistance loss of the cable 1 outer skin, improving its use quality, and also helping to extend its service life, and has high practical value.
