DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] To make the objectives, features, and advantages of the present utility model more obvious and understandable, the technical solutions in the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the specific embodiments. Obviously, the embodiments described below are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in this patent, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of this patent. Specific Embodiment 1

[0034] As Figure 1 and Figure 2 shown, this specific embodiment provides a wind power tower spraying device, including a base 3 and a tower 2. The base 3 is arranged parallel to the tower 2, and the tower 2 is used to support the tower barrel. A spraying assembly 4 is arranged on the base 3. The spraying assembly 4 includes a spray gun 404 and a control box 401. There is a telescopic assembly 402 on the control box 401. A connecting rod 403 is rotatably arranged at the front end of the telescopic assembly 402. Spray guns 404 are respectively arranged at both ends of the connecting rod 403. The spraying efficiency can be improved through the two spray guns 404. The telescopic assembly 402 can drive the spray gun 404 to move towards or away from the tower barrel. The spray gun 404 is an automatic spray gun 404 and is electrically connected to the control module.

[0035] In this specific embodiment, the spray gun 404 is connected through the telescopic assembly 402, and the connecting rod 403 on which the spray gun 404 is installed is set to be rotatable, so as to adjust the distance between each spray gun 404 and the tower barrel 1, meet the spraying requirements of various paints and tower barrels with various diameters, realize multi-purpose use of one machine, and make the use more flexible.

[0036] The telescopic assembly 402 can adopt a motor + lead screw mechanism. However, to simplify the structure, in this specific embodiment, the telescopic assembly 402 adopts a multi-stage telescopic electric cylinder, and the telescopic assembly 402 is electrically connected to the control module in the control box 401.

[0037] As Figure 2 shown, preferably, in order to reduce the number of spray guns 404 and ensure uniform spraying along the length direction of the tower barrel 1, in this specific embodiment, the control box 401 is movably arranged on the base 3 through a guide rail 305. The control box 401 is connected with a driving assembly, and the driving assembly is electrically connected to the control module; in order to improve the control accuracy, the driving assembly includes a driving motor. The driving motor is arranged at the bottom of the control box 401 and is electrically connected to the control module. A driving gear is arranged on the driving motor, and the driving gear meshes with the rack on the base 3. The rack is arranged along the length direction of the tower 2.

[0038] As Figure 3As shown in the figure, in this specific embodiment, to enable the rotation of the connecting rod 403, a rotary motor 405 is provided at the front end of the telescopic assembly 402. The rotary motor 405 is connected to the middle of the connecting rod 403, and the rotary motor 405 is electrically connected to the control module. By means of the connecting rod 403 that rotates in the vertical plane, the distances from the upper and lower spray guns 404 to the tower barrel 1 can be adjusted and kept consistent, ensuring the same spraying effect of the two spray guns 404 and further ensuring the spraying uniformity.

[0039] As Figure 3 shown in the figure, in order to further ensure the uniform thickness of the paint coating, in this specific embodiment, adjustment holes 4031 are provided at both ends of the connecting rod. The adjustment holes 4031 are straight groove holes, and the length direction of the adjustment holes 4031 is the same as the length direction of the connecting part 1. The mounting plate on the spray gun 404 can move along the adjustment holes 4031 and be locked by bolts. By setting the adjustment holes 4031 to adjust the distance between the two spray guns 404, it is avoided that the fan-shaped surfaces of the paint sprayed by the two spray guns 404 partially overlap, thus avoiding uneven thickness of the paint coating. After replacing the tower barrel 1, before the telescopic assembly 402 is telescoped, the angle of the connecting rod 403 is adjusted first to ensure that the distances from the two spray guns 404 to the tower barrel 1 are the same.

[0040] As Figure 2 and Figure 3 shown in the figure, in order to prevent paint from entering the base 3 and affecting the guide rail 305 and the rack and pinion, the base 3 includes a support frame 304. A guide rail 305 is provided at the bottom of the support frame 304. Protective sheet metals 302 are oppositely arranged on both sides of the support frame 304. A protective cover plate 301 is provided at the upper part of the support frame 304. A sliding box 4011 is provided at the bottom of the control box 401. The driving motor is arranged at the bottom of the sliding box 4011. Support legs are provided on the sliding box 4011, and the support legs are movably arranged on the guide rail 305. A support roller 4012 is rotatably arranged in the sliding box 4011. The protective cover plate 301 passes through the upper part of the support roller 4012 and penetrates the sliding box 4011, and the sliding box 4011 can move along the protective cover plate 301. In this specific embodiment, both ends of the protective cover plate 301 extend towards the bottom of the support frame 304. Tightening heads 303 and adjusting rods are respectively provided at both ends of the support frame 304. The tightening head 303 is connected to the end of the protective cover plate 301. One end of the adjusting rod is rotatably connected to the tightening head 303, and the other end is threadedly connected to the mounting plate at the end of the support frame 304. A tensioning wheel is also rotatably arranged on the support frame 304. The protective cover plate 301 is made of stainless steel steel strip.

[0041] As Figure 1 shown in the figure, in this specific embodiment, the tower 2 includes a support plate. Support rollers are rotatably arranged at both ends of the support plate. The support rollers are connected to motors, and the tower barrel 1 is placed on the support rollers and driven to rotate by friction. Both the support plate and the support frame 304 are fixed on the ground.

[0042] The control box 401 is also provided with an input module. When the operator inputs the diameter of the tower 1 and the type of paint, the control module can automatically calculate the angle of the connecting rod 403 and the telescopic displacement of the telescopic assembly 402 .

[0043] The adjustment process of the wind turbine tower spraying device is as follows:

[0044] First, according to the situation of the spraying fan, adjust the distance between the two spray guns 404 to avoid overlapping of the sprayed fan; after replacing the tower 1, input the tower diameter and paint type, the control module first drives the connecting rod 403 to rotate to ensure that the horizontal distance between the two spray guns 404 and the tower wall is the same; the control module then controls the telescopic component 402 to telescope to a set distance. Specific implementation method 2

[0046] like Figure 4 As shown, the structure of this specific embodiment is basically the same as that of specific embodiment one, with the difference being that the telescopic assembly 402 includes a six-axis robotic arm and a joint motor, the joint motor is connected to the connecting rod 403, and the joint motor can rotate and adjust the connecting rod 403 to ensure that the distance from each spray gun 404 to the cylinder wall is the same; the use of a robotic arm can also save space, allowing spraying of a larger diameter tower in a smaller space.

[0047] The use of a robotic arm can adjust the position of the spray gun 404 from more dimensions, further improving the flexibility of use.

[0048] From the above specific implementations, it can be seen that the utility model has the following beneficial effects:

[0049] 1. The spray gun 404 is connected through the telescopic component 402, and the connecting rod 403 for installing the spray gun 404 is set to be rotatable, so that the distance between each spray gun 404 and the tower 1 can be adjusted to meet the spraying use of various paints and towers of various diameters, so as to achieve one machine for multiple uses, more flexible use, and higher spraying efficiency;

[0051] 3. By providing two spray guns 404, the spraying area of the spraying assembly 4 can be increased once moved, thereby improving the spraying efficiency;

[0052] 4. By setting the connecting rod 403 to be rotatable, it can be ensured that after the diameter of the tower 1 changes, by adjusting the inclination angle of the connecting rod 403 in the vertical plane, the distance between the upper and lower spray guns 404 and the tower 1 can be kept consistent, and the spraying effects of the upper and lower spray guns 404 can be kept consistent, further ensuring the uniformity of spraying;

[0053] 5. By setting the adjustment holes 4031, the distance between the two spray guns 404 is adjusted to prevent partial overlap of the paint fan surfaces sprayed by the two spray guns 404, which may cause uneven thickness of the paint coating on the tower barrel 1 and ensure the spraying quality.

[0054] 6. By setting the protective sheet metal 302, it is possible to prevent paint from entering the base 3 from the side and adhering to the guide rail 305, which may affect the operation.

[0055] 7. By setting the protective cover plate 301, it is possible to prevent paint from entering the base 3 from the upper part, and by setting the sliding box 4011 and the support roller 4012, it is ensured that the control box 401 can move relative to the protective cover plate 301 smoothly.

[0056] 8. By setting the tensioning head 303, the adjusting rod and the tensioning wheel, it is ensured that the gap between the protective cover plate 301 and the support frame 304 is small and does not affect the movement of the control box 401.
