[0029] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] This embodiment provides a wind power surge protector. Please refer to [link / reference]. Figure 1-3 As shown, the system includes a mounting plate 100, a surge protector base 200, and a surge protector module 300. The mounting plate 100 includes a fixing plate 110 and a limiting member 120. The limiting member 120 is fixedly connected to the fixing plate 110, and the fixing plate 110 has mounting holes 111. The limiting member 120 has an inclined portion 121 and a horizontal portion 122. The inclined portion 121 has a first arc-shaped surface 1211, and the horizontal portion 122 has a second arc-shaped surface 1221. The surge protector base 200 has a limiting groove 210, which is adapted to the limiting member 120. The surge protector base 200 has a third arc-shaped surface 211 and a fourth arc-shaped surface 212. The surge protector module 300 is detachably mounted on the surge protector base 200.

[0031] Specifically, the mounting plate 100 is used to install the surge protector 200 in a designated position and limit its movement. The mounting holes 111 are used to install screws, which are used to fix the mounting plate 110 to the wind turbine. The limiting member 120 is used to limit the surge protector 200. The inclined part 121 engages with the lower part of the limiting groove 210 to initially limit the surge protector 200. After pushing the upper part of the surge protector 200, the second arc-shaped surface 1221 and the fourth arc-shaped surface 212 come into contact, and the horizontal part 122 further limits the movement with the limiting groove 210. When the surge protector 200 is disassembled, the arrangement of the first arc-shaped surface 1211 and the third arc-shaped surface 211 prevents the inclined part 121 and the surge protector 200 from damage. The surge protection module 300 is used to protect electrical equipment from lightning surges and other transient overvoltages. In use, place the mounting plate 100 at the designated position on the wind turbine, fix the fixing plate 110 with screws, and install the lightning protection module 300 onto the lightning protection base 200. First, align the lower part of the limiting groove 210 of the lightning protection base 200 with the inclined part 121. Press the upper part of the lightning protection base 200 so that the second arc-shaped surface 1221 contacts the fourth arc-shaped surface 212. Then, push the upper part of the lightning protection base 200 to separate the second arc-shaped surface 1221 from the fourth arc-shaped surface 212, and the lightning protection base 200 snaps onto the limiting member 120. When it is necessary to replace the lightning protection module 300, remove the lightning protection module 300 and directly replace it with a lightning protection module 300 of the same model. If there is no lightning protection module 300 of the same model, press down on the lightning protection base 200 and replace the lightning protection base 200 and the lightning protection module 300 as a whole.

[0032] In this embodiment, the limiting member 120 is provided with a groove 130, and the lightning protection base 200 is rotatably connected to the limiting link 220. The limiting link 220 includes a first link 221, a rotating member 222, and a second link 223. The first link 221 is connected to the rotating member 222, and the second link 223 is connected to the rotating member 222. The rotating member 222 is rotatably connected to the lightning protection base 200.

[0033] Specifically, the groove 130 is designed to provide working space for the second connecting rod 223. The limiting connecting rod 220 cooperates with the limiting member 120 to enhance the stability of the lightning protection seat 200 during installation. In use, after the lightning protection seat 200 is installed on the limiting member 120, the second connecting rod 223 is moved, causing the rotating member 222 to rotate. The rotating member 222 then moves the first connecting rod 221 towards the groove 130, thereby strengthening the connection between the lightning protection seat 200 and the limiting member 120. When disassembly is required, the operation is reversed.

[0034] In this embodiment, the lightning protection base 200 is provided with a first positioning base 230 and a second positioning base 240; the first positioning base 230 abuts against the first connecting rod 221, and the second positioning base 240 abuts against the second connecting rod 223.

[0035] Specifically, the first positioning seat 230 is used to limit the first connecting rod 221, and the second positioning seat 240 is used to limit the second connecting rod 223, so that the operator can rotate the limiting connecting rod 220 to the appropriate position.

[0036] In this embodiment, the first positioning seat 230 and the second positioning seat 240 are respectively provided with positioning grooves 250.

[0037] Specifically, the positioning groove 250 is designed so that the first link 221 or the second link 223 is not easily moved after rotating to its limit position.

[0038] In this embodiment, the second link 223 is connected to the toggle plate 260.

[0039] Specifically, the toggle plate 260 is designed to facilitate the operation of the second linkage 223 by the operator.

[0040] In this embodiment, the toggle plate 260 has several anti-slip protrusions 270 on both sides.

[0041] Specifically, the anti-slip protrusions 270 increase the friction area between the actuating plate 260 and the operator's fingers, preventing the actuating plate 260 from slipping when the operator moves it.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
