Detailed implementation manner

[0027] The embodiments of the technical solution of the present utility model will be described in detail below with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present utility model, so they are only examples and cannot be used to limit the protection scope of the present utility model.

[0028] Please refer to Figures 1 to 3 , the present utility model provides a groove cleaning device for a cast iron platform of a wind turbine, including a linear motion driving member 100, a mounting member 200, a cleaning chain 300 and an auxiliary support frame 400.

[0029] Specifically, the mounting member 200 is arranged on the linear motion driving member 100, and the linear motion driving member 100 can drive the mounting member 200 to move linearly. The cleaning chain 300 is in a long strip shape, and the cleaning chain 300 includes a plurality of brush plates 310 and a plurality of connecting members 320. The plurality of brush plates 310 are arranged in sequence, and two adjacent brush plates 310 are hinged by a connecting member 320, and the connecting member 320 can lock and fix the two brush plates 310 of the cleaning chain 300 connected thereto. Both ends of the cleaning chain 300 are fixedly connected to the mounting member 200. The auxiliary support frame 400 is arranged on the mounting member 200 and can be connected to multiple parts of the cleaning chain 300 for auxiliary support of the cleaning chain 300.

[0030] During use, first loosen all the connecting members 320, then adjust the position of each brush plate 310 according to the shape of the groove so that the initial shape of the cleaning chain 300 is consistent with the shape of the groove, then lock all the connecting members 320, and fix multiple positions of the cleaning chain 300 through the auxiliary support frame 400, then the final shape of the cleaning chain 300 can be fixed. Finally, slide the cleaning chain 300 into the groove from the end face of the initial section of the groove, and drive the mounting member 200 to move along the length direction of the groove through the linear motion driving member 100, then the cleaning chain 300 can be driven to move along the groove, and the bristles on the brush plate 310 can brush up the scum on the inner wall of the groove. Finally, through flushing, the impurities in the groove can be smoothly removed.

[0031] By adopting such a groove cleaning device, the cleaning chain can adapt to the cleaning of grooves with different cross-sections, greatly improving the convenience of using the device. After removing the impurities, it is convenient for the installation of related equipment and at the same time extends the service life of the cast iron use platform.

[0032] In this embodiment, the connecting member 320 includes a rotating shaft 321, a U-shaped connecting frame 322, a connecting plate 323, and an elastic member 324. The U-shaped connecting frame 322 and the connecting plate 323 are respectively connected to opposite ends of the brush plate 310, and shaft holes are provided on both the U-shaped connecting frame 322 and the connecting plate 323. Two adjacent brush plates 310 are rotatably hinged through the rotating shaft 321. Inner gears are sleeved and fixed inside the same side of the two shaft holes. The elastic member 324 is sleeved on the rotating shaft 321 and is located on the side away from the inner gears, and both ends of the elastic member 324 are respectively abutted against the connecting plate 323 and the U-shaped connecting frame 322. An outer gear is sleeved and fixed at one end of the rotating shaft 321 away from the elastic member 324, and the outer gear meshes with the inner gears of the two shaft holes simultaneously.

[0033] It should be noted that in specific implementation, the brush plate 310 is a brush plate 310 with steel bristles commonly used in the prior art. The linear motion driving member 100 can be a power locomotive, and the mounting member 200 is arranged on the power locomotive. The power locomotive can be an electric vehicle commonly used in the prior art or a remote control vehicle. Of course, in other embodiments, the linear motion driving member 100 can also be in other forms, such as in the form of a rod driven manually.

[0034] In the normal state, the outer gear is inserted and fixed with the two inner gears. When it is necessary to adjust the distance between two adjacent brush plates 310, the rotating shaft 321 is pulled axially along the rotating shaft 321 to make the outer gear and the two inner gears in a split state. Subsequently, any brush plate 310 is rotated to adjust the angle between the two to an appropriate position, and then the rotating shaft 321 is released. Under the action of the elastic member 324, the outer gear is inserted into the two inner gears again, so that the angles of the two brush plates 310 can be fixed, and thus the cleaning chain 300 can be adjusted to any required shape.

[0035] Specifically, the auxiliary support frame 400 includes a main support rod 410, a secondary support rod 420, and a clamping member 430. Both the main support rod 410 and the secondary support rod 420 are telescopic rod members. The main support rod 410 is vertically arranged on the mounting member 200. There are multiple secondary support rods 420, and the multiple secondary support rods 420 are arranged on the main support rod 410 at intervals and extend outward in all directions. A clamping member 430 is provided at the end of each secondary support rod 420, and the clamping member 430 can be clamped and fixed on the brush plate 310 in contact therewith.

[0036] It should be noted that the main support rod 410 and the secondary support rod 420 generally adopt the form of multiple insertion-compliant plug-ins and locking members commonly used in the prior art. By adjusting the elongation lengths of the respective plug rods, the length of the entire support rod can be adjusted.

[0037] After the shape of the cleaning chain 300 is adjusted, the lengths of the main support rod 410 and the auxiliary support rod 420 are adjusted according to the shape of the inner frame of the cleaning chain 300, so that the clamping member 430 can be clamped and fixed on the brush plate 310. Finally, it is sufficient that the clamping member 430 can be clamped and fixed on the brush plate 310. During the movement of the cleaning chain 300 in the groove, the auxiliary support frame 400 can further provide auxiliary support for the cleaning chain 300 to prevent the cleaning chain 300 from deforming, thereby improving the cleaning effect.

[0038] In this embodiment, the clamping member 430 includes a mounting plate 431, a clamping plate 432 and a bidirectional screw 433. The mounting plate 431 is connected to the auxiliary support rod 420. There are two clamping plates 432. The two clamping plates 432 are relatively and slidably arranged on the mounting plate 431. The two ends of the bidirectional screw 433 have opposite thread directions, and the two ends of the bidirectional screw 433 are respectively threadedly connected to the two clamping plates 432 through the threads thereon.

[0039] When in use, when the two clamping plates 432 are respectively located on both sides of the brush plate 310, rotating the screw clockwise can drive the two clamping plates 432 to clamp on both sides of the brush plate 310. On the contrary, rotating the screw clockwise can drive the two clamping plates 432 to loosen.

[0040] For the above-mentioned groove cleaning device of the cast iron platform of the wind turbine generator, the cleaning chain can adapt to the cleaning of grooves with different cross-sections, greatly improving the convenience of using the device. After removing impurities, it is convenient for the installation of related equipment and at the same time extends the service life of the cast iron use platform.

[0041] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
