Description

Technical Field

[0001] This utility model relates to the field of wind power bearing technology, and in particular to a carbon fiber flow guiding device. Background Technology

[0002] Wind turbine slipways are key components in wind power systems used to support and guide equipment movement. They are mainly used in yaw systems, pitch systems, and maintenance equipment to ensure power generation efficiency and equipment lifespan. To prevent shaft current from damaging the slipway bearings, grounding carbon brushes are installed on the slipway surface to divert the shaft current to the ground, reducing the impact of shaft current on the slipway.

[0003] The slide shaft diameter is very large, and the contact area between the slide and the carbon brush is close to a flat surface. However, the existing carbon brush surface has a certain curvature, which causes gaps at the contact point between the carbon brush and the slide, which is not conducive to conductivity. In addition, the slide surface is often contaminated by gearbox oil, which leads to the failure of the carbon brush to conduct electricity. If the inspection is not timely, it may cause a major accident.

[0004] Therefore, it is necessary to provide a new carbon fiber flow guiding device to solve the above problems. Utility Model Content

[0005] The technical problem solved by this utility model is to provide a carbon fiber flow guiding device that facilitates contact with the slide rail and avoids the failure of carbon brush conductivity.

[0006] To solve the above-mentioned technical problems, the carbon fiber guiding device provided by this utility model includes: a support plate, with second fixing plates symmetrically installed at both ends of the support plate, and multiple first fixing plates installed between the two second fixing plates. Multiple first carbon fiber bundles are installed on the bottom surface of the first fixing plates, and multiple second carbon fiber bundles are installed on the bottom surface of the second fixing plates. The bottom ends of the first carbon fiber bundles and the bottom ends of the second carbon fiber bundles are in the same plane. The diameter of the second carbon fiber bundles is larger than the diameter of the first carbon fiber bundles, and the second carbon fiber bundles are distributed in a "V" shape at the bottom end of the second fixing plates.

[0007] Preferably, the width of the second fixing plate is greater than the width of the first fixing plate, and the first fixing plate and the second fixing plate are fixed together by a second bolt.

[0008] Preferably, the second fixing plate is fixed to the side wall of the support plate by the first bolt, and the top surface of the second fixing plate is flush with the top surface of the support plate.

[0009] Preferably, the support plate has symmetrical mounting holes at both ends, and the screw passes through the mounting plate and the mounting holes; the screw and the nut are threadedly connected, and the nut abuts against the bottom surface of the support plate.

[0010] Preferably, the surface of the support plate is provided with a plurality of adjustment holes, and a plurality of rubber rings are placed inside the adjustment holes; an adjustment rod is placed inside the adjustment holes, and the two ends of the adjustment rod respectively abut against the rubber rings and the mounting plate.

[0011] Compared with related technologies, the carbon fiber guide device provided by this utility model has the following beneficial effects: This invention provides a carbon fiber guiding device. The first carbon fiber bundle is fixed to the bottom surface of the first fixing plate, and the second carbon fiber bundle is fixed to the surface of the second fixing plate. The bottom ends of the first and second carbon fiber bundles are in the same plane. During installation, this ensures that the carbon fiber bundles are in uniform contact with the slide surface, which is beneficial for conductivity. When gearbox oil contaminates the slide surface, the rotating slide first contacts the second carbon fiber bundle. The second carbon fiber bundle then contacts and pushes away the oil on the slide surface. The diameter of the first carbon fiber bundle is smaller than that of the second carbon fiber bundle, which protects the first carbon fiber bundle and reduces the probability of oil contact with it. Furthermore, the second carbon fiber bundle is distributed in a "V" shape at the bottom of the second fixing plate. The second carbon fiber bundle pushes the oil on the slide surface outward, further reducing the contact between the first carbon fiber bundle and the oil, thereby ensuring the conductivity of the first carbon fiber bundle.

[0014] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0015] Please see Figures 1 to 3 , Figure 1 A schematic diagram of a preferred embodiment of the carbon fiber flow guiding device provided by this utility model; Figure 2 for Figure 1The diagram shows the support plate structure. Figure 3 for Figure 1 The diagram shows a bottom view of the second fixing plate structure. A carbon fiber guiding device includes a support plate 3, with second fixing plates 10 symmetrically mounted at both ends of the support plate 3. Multiple first fixing plates 8 are installed between the two second fixing plates 10. Multiple first carbon fiber bundles 9 are mounted on the bottom surface of the first fixing plates 8, and multiple second carbon fiber bundles 11 are mounted on the bottom surface of the second fixing plates 10. The bottommost ends of the first carbon fiber bundles 9 and the second carbon fiber bundles 11 are in the same plane. The first carbon fiber bundles 9 are fixed to the bottom surface of the first fixing plates 8, and the second carbon fiber bundles 11 are fixed to the surface of the second fixing plates 10, ensuring that the bottommost ends of the first carbon fiber bundles 9 and 11 are aligned. The bottom ends are all in the same plane, ensuring uniform contact between the carbon fiber bundles and the slide surface without gaps, which facilitates the conductivity of the carbon fiber bundles. Furthermore, when gearbox oil contaminates the slide surface, the rotating slide first contacts the second carbon fiber bundle 11, which then pushes away the oil from the slide surface. The diameter of the first carbon fiber bundle 11 is smaller than the diameter of the second carbon fiber bundle 9, protecting the first carbon fiber bundle 9 and reducing the probability of oil contact. The second carbon fiber bundle 11 is distributed in a "V" shape at the bottom end of the second fixing plate 10 (as shown in the attached figure). Figure 3 As shown), the second carbon fiber bundle 11 pushes the oil on the slide surface away from the carbon fiber bundle, further reducing the contact between the first carbon fiber bundle 9 and the oil, thereby ensuring the conductivity of the first carbon fiber bundle 9.

[0016] The width of the second fixing plate 10 is greater than the width of the first fixing plate 8. In order to facilitate the installation of the second carbon fiber bundles 11 distributed in a "V" shape on the bottom surface of the second fixing plate 10, and to fix the first fixing plate 8 and the second fixing plate 10 with the second bolt 7, in order to facilitate the fixing between the first transition plate 8 and the second fixing plate 10.

[0017] The second fixing plate 10 is fixed to the side wall of the support plate 3 by the first bolt 6. The top surface of the second fixing plate 10 is flush with the top surface of the support plate 3 to facilitate fixing the second fixing plate 10 to the support plate 3.

[0018] The support plate 3 has symmetrical mounting holes 31 at both ends, and a screw 2 passes through the mounting plate 1 and the mounting holes 31. The screw 2 is threadedly connected to a nut 21, and the nut 21 abuts against the bottom surface of the support plate 3. The surface of the support plate 3 has multiple adjustment holes 32, and multiple rubber rings 4 are placed inside the adjustment holes 32. An adjustment rod 5 is placed inside the adjustment holes 32, and the two ends of the adjustment rod 5 abut against the rubber rings 4 and the mounting plate 1, respectively. The mounting plate 1 is fixed to the slide bearing end cover. When it is necessary to connect the carbon fiber bundle to the slide, an appropriate number of rubber rings 4 are placed inside the adjustment holes 32 as needed, and then the adjustment rod 5 is placed inside the adjustment holes 32 to abut against the rubber rings 4. The support plate 3 is moved so that the support plate 3 is aligned with the mounting plate 1, the adjustment rod 5 abuts against the surface of the mounting plate 1, and the carbon fiber bundle is in interference contact with the surface of the slide. The screw 2 passes through the mounting plate 1 and the mounting holes 31, and the nut 21 is connected to the screw 21 to fix the support plate 3. As usage time increases, the carbon fiber bundle gradually wears down. When the carbon fiber bundle can no longer make interference contact with the slide surface, separate the nut 21 from the screw 21, remove the support plate 1 and the adjusting rod 5, and insert an appropriate number of rubber rings 4 into the adjusting hole 32 to increase the height of the rubber rings 4 inside the adjusting hole 32. Similarly, fix the support plate 3 to one side of the mounting plate 1 in the same way. Due to the increase in the number of rubber rings 4, the distance between the fixing plate and the slide is reduced, thereby ensuring that the carbon fiber bundle makes interference contact with the slide surface again and extending the service life of the carbon fiber bundle.
