Description

Technical Field

[0001] This utility model relates to the field of wind power generation transmission technology, and more specifically, it relates to a cable guiding device for wind power generator sets. Background Technology

[0002] Wind turbine generators (referred to as "wind turbines") are devices that convert wind energy into electrical energy. They are one of the core equipment for renewable energy utilization. The electrical energy generated by wind turbine generators is transmitted through cables. During the cable transmission process, in order to ensure overall safety and stability, multiple cables are generally guided by a guide device. In the existing guide devices, the guide mechanism is integrated, and the cables need to pass through the conductor mechanism for installation, which is relatively troublesome. In addition, when the device is in use, different cables have different outer lengths, which can easily lead to shaking and slippage. There is a lack of a suitable tightening and adjustment mechanism. Furthermore, when the device is in use, multiple cables are clamped and installed separately, which is also cumbersome. There is a lack of a suitable synchronous clamping and adjustment mechanism. Utility Model Content

[0024] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0026] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0027] Please see Figures 1-3A wind turbine generator cable guiding device includes a base plate 1. Fixing seats 2 are provided on both the left and right sides of the upper surface of the base plate 1. A clamping seat 3 is detachably provided on the upper surface of each of the two fixing seats 2. A first groove 4 is formed on the upper surface of each of the two fixing seats 2. A second groove 5 is formed on the lower surface of each of the two clamping seats 3 corresponding to the first groove 4. Multiple first grooves 4 and second grooves 5 are spaced apart. Positioning rods 6 are symmetrically provided on the upper surface of each of the two fixing seats 2. Positioning holes 7 are formed on each of the two clamping seats 3 corresponding to multiple positioning rods 6. Positioning rings 8 are provided on the outer end surfaces of multiple positioning rods 6. Positioning rings 8 and positioning rods 6 are threadedly connected. A tensioning mechanism is detachably provided at the center position of the upper surface of the base plate 1, corresponding to multiple sets of first grooves 4 and second grooves 5.

[0028] In this embodiment, multiple cables are initially installed in the first groove 4 of the fixing seat 2. After the initial installation, the clamping seat 3 is installed. The positioning rod 6 and the positioning hole 7 are installed and positioned in cooperation. The positioning ring 8 and the positioning rod 6 are locked in a threaded fit. The first groove 4 and the second groove 5 guide the installation of the cables.

[0029] More specifically, the tensioning mechanism adjusts the tension of the excess cable.

[0030] Please see Figure 1 , Figure 3 and Figure 4 As one implementation method for adjusting the clamping: a clamping rod 9 is provided through multiple second grooves 5 on the upper end face of each of the two clamping seats 3. An arc-shaped plate 10 is provided at the bottom end of each clamping rod 9. A clamping plate 11 is connected to the upper end of the multiple clamping rods 9 on the same side. An adjusting rod 12 is rotatably provided on the upper end face of the clamping seat 3. An adjusting hole 13 is opened on the clamping plate 11 corresponding to the adjusting rod 12. The adjusting rod 12 and the adjusting hole 13 are threadedly connected.

[0031] Specifically, rotating the adjusting rod 12, which is threaded into the adjusting hole 13, causes the clamping plate 11 to drive the clamping rod 9 to rise and fall synchronously. The clamping rod 9 then drives the bottom arc plate 10 to rise and fall, thus achieving the clamping operation after the internal cable is installed.

[0032] Please see Figure 1 , Figure 2 and Figure 5As one implementation of the tensioning mechanism: multiple tensioning mechanisms each include a support sleeve 14, a support rod 15, and a retaining ring 16. The support sleeve 14 is detachably mounted on the base plate 1. The support rod 15 is slidably adjustable relative to the support sleeve 14. The retaining ring 16 is mounted on the upper end of the support rod 15. Each of the multiple support sleeves 14 has a first locking hole 17. Each of the multiple support rods 15 has a second locking hole 18. Multiple second locking holes 18 are spaced apart. The first locking holes 17 and the second locking holes 18 are connected by bolts. Each of the multiple support sleeves 14 has a connector 19 at its bottom end. The upper surface of the base plate 1 has a connecting hole 20 corresponding to each connector 19. The connector 19 and the connecting hole 20 are threadedly connected.

[0033] Specifically, when the cable tension is inappropriate, the tensioning mechanism is installed. The support sleeve 14 is installed relative to the base plate 1, the connector 19 and the connecting hole 20 are threaded together, and the top retaining ring 16 clamps the cable to achieve tension adjustment. The support rod 15 is adjusted to a suitable height, the first locking hole 17 and the second locking hole 18 are aligned, and the bolt is passed through and tightened to fix it, which facilitates tension adjustment. When tension adjustment is not required, the tensioning mechanism is disassembled, and guides are installed on both sides.

[0034] Please see Figure 1 and Figure 2 As one embodiment of the base plate 1: the base plate 1 is provided with fixing holes 21, and multiple fixing holes 21 are provided.

[0035] Specifically, the bolts pass through the fixing holes 21 on the base plate 1 and are locked to the external ground to achieve overall stable locking.

[0036] In summary, the overall equipment is in use:

[0037] In the initial installation state, the cable is initially installed in the first groove 4 of the fixing seat 2 on both sides. After the initial installation, the clamping seat 3 is installed. The positioning hole 7 of the clamping seat 3 is installed and positioned in accordance with the positioning rod 6 of the fixing seat 2. After the initial installation, the positioning ring 8 and the positioning rod 6 are threaded together to achieve installation and locking.

[0038] When in the guide clamping state, rotate the adjusting rod 12. The adjusting rod 12 and the adjusting hole 13 are threaded together. The clamping plate 11 drives the clamping rod 9 to slide and rise relative to the clamping seat 3. The clamping rod 9 drives the bottom arc plate 10 to rise and adjust, so as to realize the synchronous clamping and installation of the internally installed cables.

[0039] When in the tension adjustment state, the tensioning mechanism is disassembled or reassembled depending on the length of the cable to be installed. When the cable to be installed in this section is long, the tensioning mechanism is installed and adjusted. The connector 19 and the connector hole 20 are threaded together to achieve the initial installation of the support sleeve 14. The support rod 15 slides and rises relative to the support sleeve 14. The rise and fall are adjusted to a suitable position. The first locking hole 17 and the second locking hole 18 are tightened to achieve fixed locking. The cable is installed and limited by the corresponding retaining ring 16. The retaining ring 16 drives the cable in the middle position to rise and fall to achieve tension adjustment.

[0040] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
