Description

A redundant arrangement structure for wind power tower switch components Technical Field

[0001] This utility model relates to the field of switch assembly technology, and in particular to a redundant arrangement structure for a wind power tower switch assembly. Background Technology

[0002] With the accelerated global energy structure transformation, wind power, as an important component of clean energy, has seen its installed capacity and single-unit power continuously increase. The wind turbine tower (wind turbine tower) serves as the core supporting structure of the wind turbine, integrating a large number of electrical devices, including the main control system, converters, transformers, and various switching components. Among these, the switching components, as a critical link in power distribution and protection, directly affect the operating efficiency and safety of the wind turbine.

[0003] Traditional wind power towers typically use a single main switch design for their switch components. When the main switch is damaged due to overload, short circuit, or aging, the unit needs to be shut down for maintenance or replacement. Since wind turbines are usually located in remote areas, it takes a long time for maintenance personnel to arrive on-site, and replacing the switch requires disconnecting the power supply, resulting in prolonged shutdowns that directly cause power generation losses and may affect grid dispatch plans. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a redundant arrangement structure for wind power tower switch components. In practical use, this arrangement structure, by utilizing backup switches, greatly shortens the time required for power outages, avoids prolonged downtime, and reduces losses.

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

[0006] A redundant arrangement structure for a wind power tower switch assembly includes a rectangular frame, within which a rotating plate is disposed. The rotating plate has two rectangular openings extending from front to back, and each rectangular opening has a strip-shaped opening at its inner top. A switch housing is disposed within each of the two rectangular openings, and the upper end of each switch housing has a corresponding strip-shaped opening. A push-button switch is embedded on the rear side of the left switch housing and the front side of the right switch housing. Two first hemispherical conductive blocks are symmetrically mounted on the upper end of each switch housing. A driving mechanism is also included to drive the rotating plate to rotate.

[0007] Preferably, L-shaped connecting plates are fixedly connected to both the left and right sides of the rectangular frame, and each L-shaped connecting plate has two mounting holes.

[0008] Preferably, the rectangular frame has a rectangular opening at its inner top.

[0009] Preferably, the pressing surface of the push switch does not protrude beyond the corresponding side of the switch housing.

[0010] Preferably, the driving mechanism includes a drive motor installed at the lower end of the rectangular frame, the output shaft of the drive motor passing through the rotating plate and rotatably connected to the inner top of the rectangular frame, and the output shaft of the drive motor being fixedly connected to the rotating plate.

[0011] Preferably, a rectangular groove is provided at the top of the right side portion of the rectangular frame, and a sliding strip is slidably connected in the rectangular groove. The upper end of the sliding strip is elastically connected to the top of the inner side of the rectangular groove by a spring, and two second hemispherical conductive blocks are symmetrically installed at the lower end of the sliding strip.

[0012] Compared with the prior art, the advantages of this utility model are as follows:

[0013] When the main switch on the right fails, the drive motor starts, causing the rotating plate to rotate half a turn. This automatically aligns and contacts the conductive block of the backup switch housing on the left, quickly establishing a backup power supply path. The switching process is short, significantly reducing power outage time. The initial compression design of the spring ensures tight contact of the conductive blocks, preventing poor contact. Furthermore, the faulty switch housing can be directly removed for maintenance through the rectangular access port, greatly simplifying the maintenance process and reducing maintenance costs and risks.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Referring to Figures 1-4, a redundant arrangement structure for a wind power tower switch assembly includes a rectangular frame 1, a rotating plate 5 inside the rectangular frame 1, and L-shaped connecting plates 3 fixedly connected to both the left and right sides of the rectangular frame 1. Each L-shaped connecting plate 3 has two mounting holes 4 to facilitate the installation of the rectangular frame 1. The rotating plate 5 has two rectangular openings 7 extending through the front and back. Each rectangular opening 7 has a strip-shaped opening 15 at its inner top. The rectangular frame 1 has a rectangular loading and unloading opening 6 at its inner top.

[0021] Each of the two rectangular openings 7 contains a switch housing 8, with a corresponding strip-shaped opening 15 extending through the upper end of each switch housing 8. A push-button switch 9 is embedded in the rear of the left switch housing 8 and the front of the right switch housing 8. Two first hemispherical conductive blocks 13 are symmetrically mounted on the upper end of each switch housing 8. The two poles of the push-button switch 9 are electrically connected to the corresponding two first hemispherical conductive blocks 13. The pressing surface of the push-button switch 9 does not protrude from the side of the corresponding switch housing 8, facilitating easy removal and placement. A rectangular groove 10 is provided at the top right side of the rectangular frame 1. A sliding strip 12 is slidably connected in the rectangular groove 10. The upper end of the sliding strip 12 is elastically connected to the top of the rectangular groove 10 through a spring 11. Two second hemispherical conductive blocks 14 are symmetrically installed at the lower end of the sliding strip 12. Furthermore, the two second hemispherical conductive blocks 14 are electrically connected to the two power supply wires of the circuit respectively. With the setting of the spring 11, the first hemispherical conductive block 13 and the second hemispherical conductive block 14 can be kept in close contact.

[0022] It also includes a drive mechanism for driving the rotating plate 5 to rotate. The drive mechanism includes a drive motor 2 installed at the lower end of the rectangular frame 1. The output shaft of the drive motor 2 passes through the rotating plate 5 and is rotatably connected to the inner top of the rectangular frame 1. The output shaft of the drive motor 2 is fixedly connected to the rotating plate 5. A wireless module (not shown) is also provided to remotely control the start of the drive motor 2.

[0023] In this utility model, when the right-side push switch 9 malfunctions, the drive motor 2 starts, and its output shaft drives the rotating plate 5 to rotate 180° clockwise or counterclockwise, so that the positions of the two switch housings 8 are interchanged. After rotation, the conductive block 13 of the spare switch housing 8, which was originally located on the left side, automatically aligns and contacts the conductive block 14 of the sliding bar 12, forming a spare switch power supply path, reducing the power outage time. It is only necessary to remove the switch housing 8 located on the left side at this time for maintenance.

[0024] Initially, spring 11 is in a compressed state. After the second hemispherical conductive block 14 on the right rotates away, the sliding bar 12 and the two first hemispherical conductive blocks 13 will move down a short distance under the elastic action of spring 11. Subsequently, when the second hemispherical conductive block 14 on the left rotates to the position of the two first hemispherical conductive blocks 13, it will push the two first hemispherical conductive blocks 13 upward and keep spring 11 in a compressed state to ensure tight contact and avoid poor contact.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
