Description

Technical Field

[0001] This utility model relates to the field of blade spraying technology, specifically to an automatic spraying device for blade surface coating. Background Technology

[0002] Wind turbine blades require a coating primarily to protect them from harsh environmental conditions and extend their service life. The coating, through a multi-layered structure of primer, gel coat, and topcoat, enhances abrasion resistance, weather resistance, and anti-aging properties, while reducing dust accumulation, thereby maintaining blade aerodynamic efficiency and reducing maintenance frequency.

[0003] When the spraying equipment is working, paint is added to the inside of the tank in advance for use. Traditional spraying equipment does not have the function of stirring the pre-stored paint. If the paint is left to stand for a long time, it is very easy for it to separate, which will affect the use effect of the paint. Utility Model Content

[0015] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0016] like Figures 1-4 As shown, this utility model provides a technical solution: an automatic spraying device for blade surface coating, comprising: Base 1; Automatic spraying mechanism 2 is set on the top of base 1 and is used to spray both sides of the blade simultaneously. The blade positioning mechanism 3 is located on the top of the base 1 and is used to support the blade. The automatic spraying mechanism 2 includes a storage tank 25. A rotating shaft 252 is rotatably connected to the top of the storage tank 25. A stirring shaft 253 located in the inner cavity of the storage tank 25 is fixedly installed at the bottom of the rotating shaft 252. A stirring paddle 254 is fixedly installed on the outer wall of the stirring shaft 253. A gear 255 is fixedly connected to the top of the rotating shaft 252. A filling port 251 is opened at the top of the storage tank 25. During the spraying operation, the stationary rack 24 will cause the gear 255 to rotate. The gear 255 will simultaneously drive the rotating shaft 252 and the stirring shaft 253 to rotate, thereby driving the stirring paddle 254 to rotate in the inner cavity of the storage tank 25. This mixes the paint stored in the inner cavity of the storage tank 25, avoiding the problem of paint segregation that easily occurs when the paint is left to stand for a long time.

[0017] As one implementation method in this embodiment, such as Figure 1 As shown, the automatic spraying mechanism 2 also includes a support leg 21, which is fixedly installed on the top of the base 1. A support frame 22 is fixedly installed at the end of the support leg 21, and a support rod 23 is fixedly installed on the back of the support frame 22. A rack 24 is fixedly installed at the end of the support rod 23. The front of the rack 24 meshes with the back of the gear 255. The support leg 21 is used to support the support frame 22, and the support rod 23 is used to fix and support the rack 24 with the help of the support frame 22. Since the front of the rack 24 meshes with the back of the gear 255, the gear 255 will rotate when it moves left and right.

[0018] As one implementation method in this embodiment, such as Figure 2As shown, a track rod 221 is fixedly installed between the two sides of the inner wall of the support frame 22, and a lead screw 222 is rotatably connected between the two sides of the inner wall of the support frame 22. A movable seat 223 is provided on the outer wall of the track rod 221 and the lead screw 222. A servo motor 224 is fixedly installed on the right side of the support frame 22. The output shaft of the servo motor 224 is fixedly connected to the end of the lead screw 222. Controlling the servo motor 224 to work can drive the lead screw 222 to rotate. The lead screw 222 is threadedly connected to the movable seat 223, which can then push the movable seat 223 to slide left and right on the outer wall of the track rod 221. This allows adjustment of the overall left and right position of the storage tank 25 and the spray pump 26, facilitating the spraying operation.

[0019] As one implementation method in this embodiment, such as Figure 2 As shown, the storage tank 25 is fixedly installed on the top of the movable base 223. The top of the movable base 223 is fixedly installed with a spray pump 26. The input end of the spray pump 26 is fixedly connected to the bottom of the storage tank 25, and the output end of the spray pump 26 is fixedly connected to a three-way pipe 27. By controlling the operation of the spray pump 26, the paint inside the storage tank 25 can be extracted and then transported through the three-way pipe 27 to the inside of the two branch pipes 28, which facilitates the spraying operation.

[0020] As one implementation method in this embodiment, such as Figure 2 As shown, a branch pipe 28 is fixedly connected to the outer wall of the three-way pipe 27, and a nozzle 29 is fixedly connected to the branch pipe 28. When the spray pump 26 is running, the paint will be sprayed from the two sets of nozzles 29, which realizes the function of spraying both sides of the blade at the same time, thereby improving the efficiency of the spraying work.

[0021] As one implementation method in this embodiment, such as Figure 4 As shown, the blade positioning mechanism 3 includes a support 31, which is fixedly installed on the top of the base 1. A mating seat 32 is fixedly installed on the top of the support 31. When installing the blade, the end of the blade is inserted into the interior of the mating seat 32, and the blade is in a vertical state, thus completing the temporary positioning of the blade.

[0022] As one implementation method in this embodiment, such as Figure 4 As shown, a support member 33 is fixedly installed on the side of the mating seat 32, and an electric telescopic rod 34 is fixedly installed on the outer wall of the support member 33. A clamping block 35 is fixedly installed on the telescopic end of the electric telescopic rod 34. After the blade is inserted into the interior of the mating seat 32, the electric telescopic rod 34 is controlled to extend, which can drive the clamping block 35 to move toward the outer wall of the blade, thus realizing the function of clamping the blade.

[0023] Working principle: During use, paint is added to the inner cavity of the storage tank 25 beforehand. The end of the blade is inserted into the interior of the fitting seat 32, and the blade is made to be in a vertical position. The electric telescopic rod 34 is extended, which can drive the clamping block 35 to move towards the outer wall of the blade, thus realizing the function of clamping the blade. The servo motor 224 is controlled to work, which can drive the lead screw 222 to rotate, thereby pushing the moving seat 223 to slide left and right on the outer wall of the track rod 221. This can adjust the left and right position of the storage tank 25 and the spray pump 26 as a whole. At the same time, the spray pump 26 is controlled to run, and the paint will be sprayed from the two sets of nozzles 29, thus realizing the function of spraying both sides of the blade simultaneously. During the spraying work of the storage tank 25 moving left and right, since the front of the rack 24 meshes with the back of the gear 255, the gear 255 will rotate when it moves left and right, which drives the stirring paddle 254 to rotate in the inner cavity of the storage tank 25, mixing the paint stored in the inner cavity of the storage tank 25.

[0024] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
