DETAILED DESCRIPTION

[0026] Please refer to Figures 1-6The present invention provides a technical solution: a wind turbine blade spraying device, comprising a spraying vehicle 1, wherein a drive box 4 is fixedly provided on the upper surface of the spraying vehicle 1; a spraying rod 2 is slidably connected to the lower surface of the spraying vehicle 1, and the spraying rod 2 can reciprocate to spray the generator blades; a material guide pipe 21 is connected to the spraying rod 2, and the material guide pipe 21 is connected to a storage barrel 22; a driving rod 3 is slidably connected to the spraying rod 2, and the end of the driving rod 3 away from the spraying rod 2 is rotatably connected to a driving disk 5, and the rotating shaft of the driving disk 5 is connected to the driving member in the drive box 4; the spraying vehicle 1 is also provided with a curing component that can immediately cure after the spraying rod 2 sprays the generator blades.

[0027] During operation: Place the fan blade D under the spraying vehicle, as shown in the following figure: Figure 1 As shown, the device is then activated, and the drive motor within the drive box 4 rotates the drive disc 5. This rotation acts on the rotatably connected drive rod 3, causing the drive rod 3 to generate a push-pull motion. Because the drive rod 3 is slidably connected to the spray rod 2, this push-pull motion translates into the spray rod 2 sliding back and forth across the lower surface of the spray vehicle 1. Simultaneously, the paint within the reservoir 22 is delivered to the spray rod 2 via the guide tube 21. During this reciprocating motion, the spray rod 2 evenly sprays the generator blades.

[0028] The spray rod 2 cooperates with the paint delivered by the guide tube 21 during its reciprocating motion to evenly cover the generator blades, effectively avoiding problems such as uneven thickness and spraying leaks that are prone to occur in manual spraying, significantly improving the quality stability of the blade spraying, and ensuring the consistency of the coating protection effect.

[0029] As a further solution of the present invention, the curing assembly is a group and is symmetrically arranged about the spraying vehicle 1. The curing assembly includes a sliding column 6 fixedly connected to the end of the spraying rod 2. The end of the sliding column 6 away from the spraying rod 2 is provided with a curing plate 7 capable of curing the generator blades. The upper end of the fixing plate 7 is slidably connected to a limiting plate 8. A return spring 9 capable of resetting the curing plate 7 is fixedly connected between the curing plate 7 and the limiting plate 8. The limiting plate 8 is fixedly connected to the sliding column 6; the curing plate 7 is provided with a driving cylinder 10 that can be brought close to the generator blades to accelerate the curing of the generator blades;

[0030] The lower end of the curing plate 7 is fixedly connected to a sliding rod 14, and the end of the sliding rod 14 away from the curing plate 7 is slidably connected to a sliding plate 15, and the end of the sliding plate 15 away from the fixed plate 7 is fixedly connected to a baffle 13, and the baffle 13 is fixedly connected to the spraying vehicle 1.

[0031] When the spraying rod 2 completes the spraying work on the generator blade, the curing assembly symmetrically arranged on both sides of the spraying vehicle 1 immediately cures the paint surface of the sprayed wind power generator blade;

[0032] Specifically, the sliding column 6 fixedly connected with the end of the spraying rod 2 reciprocates synchronously with the spraying rod 2, and the spraying rod 2 drives the curing plate 7 to reciprocate through the limiting plate 8, so as to cure the paint surface of the generator blade cover. Figure 2 As shown in Figure 3 When the curing plate 7 moves to the right to the half stroke of the sliding plate 15,

[0033] The driving cylinder 10 on the curing plate 7 is started, and the curing plate 7 is pushed to move towards the direction of the generator blade, so that the drying hole on the curing plate 7 is closer to the infrared lamp to dry the generator blade at a closer distance, so as to accelerate the curing process of the sprayed coating of the blade.

[0034] As a further scheme of the application, the curing plate 7 is provided with an air flow plate 11 capable of protecting the curing plate 7 and reducing the adhesion of spraying material, the lower end of the air flow plate 11 is fixedly connected with an air bag 12 capable of conveying air flow on the air flow plate 11 when the curing plate 7 moves to cure the generator blade, and the end of the air bag 12 away from the fixed plate 7 is fixedly connected with a baffle 13; the fixed end of the driving cylinder 10 is fixedly connected with the lower end of the air flow plate 11.

[0035] When working, as shown in Figure 2 As shown in Figure 3 During the movement of the curing plate 7 to the right, the curing plate 7 and the air flow plate 11 are compressed; when the air bag 12 is compressed, the internal gas is extruded, the generated air flow is conveyed to the surface of the air flow plate 11 through the structure channel of the air flow plate 11, and the air flow plate 11 is arranged on the curing plate 7, so that the conveyed air flow forms an air curtain on the surface of the curing plate 7, effectively blocks the residual spraying material after the spraying work from adhering to the curing plate 7, and protects the curing plate 7. The air curtain effectively blocks the residual spraying material after the spraying work from adhering to the surface of the curing plate 7, reduces the pollution and erosion of the spraying material to the curing plate, reduces the cleaning and maintenance cost of the curing plate, and prolongs the service life of the curing plate; the timely conveying of the air flow and the formation of the air curtain ensure that the curing plate always maintains a clean surface when it is close to the blade for curing work, avoids the influence of the adhered spraying material on the curing effect or the pollution of the blade, and guarantees the stability and reliability of the curing work.

[0036] As a further scheme of the present application, the spraying vehicle 1 is provided with a cleaning rod 16 capable of removing floating dust and soluble contaminants on the generator blade before the spraying rod 2 sprays the generator blade, the upper surface of the cleaning rod 16 is fixedly connected with a positioning plate 23; the positioning plate 23 is fixedly connected with the spraying rod 2 through a connecting rod 17; the connecting rod 17 is slidingly connected on the spraying vehicle 1; the connecting rod 17 is slidingly connected on the cleaning rod 16, and a pressure spring 18 is arranged between the cleaning rod 16 and the connecting rod 17 to make the cleaning rod 16 close to the surface of the generator blade.

[0037] When working: when the device is started, the cleaning rod 16 performs pretreatment work before the spraying rod 2 sprays the generator blade. The positioning plate 23 on the upper surface of the cleaning rod 16 is fixedly connected with the spraying rod 2 through the connecting rod 17, and as the spraying rod 2 starts to reciprocate under the driving action, the connecting rod 17 moves synchronously with the spraying rod 2, and at the same time, the connecting rod 17 slides on the spraying vehicle 1 and the cleaning rod 16, driving the cleaning rod 16 to move. During the movement of the cleaning rod 16, the pressure spring 18 arranged between the cleaning rod 16 and the connecting rod 17 is always in a compressed state, and the spring's elastic force continuously pushes the cleaning rod 16, so that the cleaning rod 16 closely adheres to the surface of the generator blade; it ensures that the cleaning rod 16 can effectively contact the surface of the blade, and in the process of synchronous reciprocating with the spraying rod 2, it wipes and removes the floating dust and soluble contaminants on the blade, providing a clean surface basis for the subsequent spraying of the spraying rod 2, and avoiding the influence of contaminants on the adhesion effect of the paint.

[0038] As a further scheme of the present application, the cleaning rod 16 is connected with a water storage cylinder 20 through a liquid guide pipe 19, and the water in the water storage cylinder 20 can provide humidity for the cleaning rod 16 through the liquid guide pipe 19, so that the cleaning rod 16 can wipe the floating dust and contaminants on the generator blade.

[0039] When the cleaning rod 16 performs the pretreatment operation, it is communicated with the water storage cylinder 20 through the liquid guide pipe 19, and the water in the water storage cylinder 20 can continuously provide humidity for the cleaning rod 16 through the liquid guide pipe 19. When the device is started, the spraying rod 2 starts reciprocating motion under the driving action, and the cleaning rod 16 connected with the spraying rod 2 through the connecting rod 17 and the positioning plate 23 moves synchronously, the connecting rod 17 slides on the spraying vehicle 1 and the cleaning rod 16, and drives the cleaning rod 16 to be close to the surface of the generator blade. At this time, the pressure spring 18 between the cleaning rod 16 and the connecting rod 17 is in a compressed state, and the cleaning rod 16 is tightly attached to the surface of the blade by the elastic force, and the water transported by the water storage cylinder 20 through the liquid guide pipe 19 keeps the cleaning rod 16 in a wet state. In the process of reciprocating motion of the cleaning rod 16 with the spraying rod 2, the wet cleaning rod surface can more effectively absorb and wipe the dust on the blade, and at the same time, the soluble pollutants are dissolved, the cleaning effect is enhanced, and the surface of the blade is ensured to be clean before the spraying rod 2 performs the spraying operation, so that the adhesion quality of the subsequent paint is further improved.

[0040] As a further scheme of the present application, the lower surface of the cleaning rod 16 can detachably install a cleaning brush.

[0041] As a further scheme of the present application, the curing plate 7 is provided with drying holes and infrared lamps, and the drying holes and the infrared lamps are alternately arranged.

[0042] When the curing plate 7 cures the sprayed generator blade, the alternately arranged drying holes and infrared lamps on the curing plate 7 are started synchronously. After the infrared lamp is powered on, infrared radiation is emitted, which directly acts on the coating on the surface of the blade, and the internal solvent of the coating is rapidly volatilized by using the thermal effect of the infrared ray, so that the curing reaction of the coating is accelerated; at the same time, the drying holes continuously output hot air flow, and the hot air flow forms uniform heat circulation on the surface of the blade, and cooperates with the radiation heat of the infrared lamp. In the process of synchronous movement of the curing plate 7 with the spraying rod 2, the alternately arranged drying holes and infrared lamps can comprehensively cover the surface of the blade, so that the coating in different areas of the blade can be uniformly heated and subjected to the action of the air flow, and the problems of insufficient or excessive heating in local curing are avoided, until the curing operation of the entire spraying area of the blade is completed.

[0043] As a further scheme of the present application, the water storage cylinder 20 and the material storage cylinder 22 are both provided with a material inlet.
