Description

Technical Field

[0001] This invention relates to the field of wind power generation technology, and in particular to a cable installation device inside a wind power tower. Background Technology

[0002] Wind power generation converts the kinetic energy of wind into mechanical kinetic energy, and then into electrical kinetic energy. The principle of wind power generation is to use wind to drive the rotation of windmill blades, and then use a speed increaser to increase the rotation speed, thereby driving a generator to produce electricity. According to windmill technology, a breeze speed of approximately three meters per second (a very light breeze) is sufficient to start generating electricity. Wind power generation is becoming increasingly popular worldwide because it does not require fuel and does not produce radiation or air pollution. Wind turbine towers contain cables that transmit electrical energy. There are usually multiple cables, and to ensure stable installation of these cables within the wind turbine tower, an internal cable installation device for wind turbine towers is urgently needed.

[0003] However, existing cable installation devices inside wind turbine towers have limited functionality, cannot stably install multiple cables according to their diameter, and cannot adjust the height of the installation device according to the actual height of different wind turbine towers, resulting in poor performance. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing cable installation devices inside wind power towers, which have limited functionality, cannot stably install multiple cables according to their diameter, and cannot adjust the height of the installation device according to the actual height of different wind power towers, resulting in poor performance. Therefore, this invention proposes a cable installation device for inside wind power towers.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An internal cable installation device for a wind power tower includes multiple fixed seats. Each pair of fixed seats has a sliding groove on its adjacent side. A guide seat is slidably mounted on the inner wall of the sliding groove. A common movable seat is fixedly welded to the adjacent side of each pair of guide seats. Each pair of fixed seats has a groove on its opposite side. A common through hole is formed on the inner wall of the sliding groove and the corresponding groove on their adjacent sides. Bolts are threaded onto the opposite sides of each pair of guide seats, and the bolts are located within their respective through holes. A knob is fixedly welded to the bolt, and the knob contacts the inner wall of the corresponding groove. Each of the multiple fixed seats has a slot on its top side and a retaining seat fixedly welded to its bottom side. Each retaining seat has a rectangular hole on one side, and the retaining seat is adapted to the corresponding slot.

[0007] A stabilizing mechanism includes multiple first rectangular frames, each first rectangular frame being fixedly welded to a corresponding fixed base. A rectangular rod is slidably disposed on each first rectangular frame. A spring is fixedly welded to the inner wall of each first rectangular frame. The end of the spring away from the fixed base is fixedly welded to the rectangular rod. The rectangular rod extends into a corresponding slot and is adapted to a corresponding rectangular hole.

[0008] The positioning mechanism includes multiple second rectangular frames. Two second rectangular frames are fixedly welded to the top side of the same movable seat. A horizontally arranged threaded rod is rotatably connected to the inner wall of the second rectangular frame. Two positioning plates are threadedly connected to the threaded rod. A sprocket is fixedly sleeved on the threaded rod. The same chain is drivenly connected to the corresponding two sprockets.

[0009] In a preferred embodiment, each of the rectangular rods has a tie rod fixedly welded to its top side, and each of the tie rods has anti-slip texture.

[0010] In a preferred embodiment, a circular groove is formed on the inner wall of the second rectangular frame, and the inner ring of the bearing is fixedly sleeved on the threaded rod, and the outer ring of the bearing is fixedly welded to the inner wall of the corresponding circular groove.

[0011] In a preferred embodiment, a limiting groove is formed on the bottom inner wall of a plurality of second rectangular frames, and a connecting seat is fixedly welded to the bottom side of a plurality of positioning plates, the connecting seat being slidably disposed in the corresponding limiting groove.

[0012] In a preferred embodiment, handwheels are fixedly welded to the front ends of the plurality of threaded rods located on the right side, and anti-slip pads are installed on the plurality of handwheels.

[0013] In a preferred embodiment, the threaded rod is provided with two sets of external threads, the two sets of external threads having the same pitch and opposite directions of rotation.

[0014] In a preferred embodiment, each of the plurality of movable seats has four circular holes on its top side, and the four circular holes are equally spaced.

[0015] In a preferred embodiment, mounting plates are fixedly welded onto each of the plurality of mounting bases, and mounting holes are provided on each of the plurality of mounting plates.

[0016] In this invention, an internal cable installation device for a wind turbine tower is described. The device involves selecting a corresponding number of fixed seats based on the height of the wind turbine tower. Pulling a pull rod causes a rectangular rod to move, compressing a spring and placing a mounting bracket in the corresponding slot. Releasing the pull rod allows the rectangular rod to engage with the corresponding rectangular hole under the spring force, thus fixing the two fixed seats. Rotating a knob causes a bolt to rotate. When the bolt stops contacting the inner wall of the groove, the restriction on the movable seat is released. The height of the movable seat can then be adjusted as needed. After the height is adjusted, the knob is rotated in the opposite direction to fix the movable seat with bolts, facilitating height adjustment during installation.

[0017] In this invention, a cable installation device inside a wind power tower is described. The cable is placed into a round hole, and then a handwheel is turned. The rotation of the handwheel drives the threaded rod to rotate, and the rotation of the threaded rod drives the sprocket to rotate. The sprocket drives the corresponding two threaded rods to rotate simultaneously, and the rotation of the threaded rods drives the corresponding two positioning plates to move closer to each other. The positioning plates can then fix multiple cables.

[0018] This invention features a reasonable structural design and simple operation. It can stably install multiple cables according to their diameter, and the height of the installation device can be adjusted according to the height of different wind turbine towers. It has good performance and high work efficiency, and is worth promoting. Attached Figure Description

[0038] Working principle: First, select the appropriate number of fixing seats 1 according to the height of the wind turbine tower. Pull the pull rod, and the movement of the pull rod will move the rectangular rod 15. The movement of the rectangular rod 15 will compress the spring 16, placing the clamping seat 12 into the corresponding clamping slot 11. Then release the pull rod, and under the action of the spring force 16, the rectangular rod 15 will engage with the corresponding rectangular hole 13, thus fixing the two fixing seats 1. Rotate the knob 9, and the rotation of the knob 9 will drive the bolt 8... When the knob 9 is no longer in contact with the inner wall of the groove 7, the restriction on the movable seat 5 is released. Then, adjust the height of the movable seat 5 as needed. After the height of the movable seat 5 is adjusted, rotate the knob 9 in the opposite direction and fix the movable seat 5 with the bolt 8. Then, install the fixed seat 1 on the inner wall of the wind turbine tower with the mounting plate 2. Put the cable into the round hole 10 according to the number of cables. Then, turn the handwheel 25. The rotation of the handwheel 25 drives the threaded rod 18 to rotate. The rotation of the threaded rod 18 drives the sprocket 19 to rotate. The sprocket 19 drives the chain 20 to drive the two corresponding threaded rods 18 to rotate at the same time. The rotation of the threaded rod 18 drives the two corresponding positioning plates 21 to move closer to each other. The positioning plates 21 can fix multiple cables.
