For example, a wind turbine is composed of multiple core components, and wind turbine blades are undoubtedly one of the most important components of the unit.

At present, most of the surface coatings of wind turbine blades are prepared by manual roller coating or spraying. Due to the large size of wind turbine blades (for example, the length of the blades is mostly more than 100 meters), and the blades are three-dimensional special-shaped components, the manual roller coating or spraying method has the limitations of low protection efficiency, difficult quality assurance, high labor intensity, and poor construction environment.

[0035] In order to conveniently spray different positions of the outer wall of special-shaped components, such as Figure 1 and Figure 4-5As shown, the spraying mechanism 2 includes two movable frames 201, and the third hydraulic cylinders 203 are fixedly installed on the top of the two movable frames 201, and the output ends of the two third hydraulic cylinders 203 are provided with movable plates 205. The inner wall of the movable plate 205 is rotatably installed with a second rotating tooth plate 207, and a nozzle 208 is movably installed at the middle position of the inner wall of the second rotating tooth plate 207. Fixed plates 214 are fixedly installed on both sides of the bottom of the movable plate 205, and heating plates 215 are fixedly installed on the opposite sides of the two fixed plates 214. The wheel group installed at the bottom of the movable frame 201 enables it to move on the outside of the special-shaped component. The spraying mechanism 2 can be controlled to work by a control system, and the horizontal position of the nozzle 208 can be adjusted by rotating the second rotating tooth plate 207. The height of the nozzle 208 can be adjusted by working the two third hydraulic cylinders 203, so that the spraying mechanism 2 can conveniently perform spraying operations on different positions of the outer wall of the special-shaped component, which can improve the spraying efficiency of the special-shaped component.

[0036] In order to enable the clamping plate 107 to stably clamp and flip the special-shaped component, Figure 2-3 As shown, a fixed groove 104 is provided on the inner wall of the mounting plate 103, and the inner wall of the fixed groove 104 is rotatably connected to the outer wall of the adjacent first rotating tooth plate 105, and movable grooves 106 are provided at opposite ends of the two first rotating tooth plates 105, and the inner walls on both sides of the movable groove 106 are respectively movably connected to the outer walls of one end of the two adjacent clamping plates 107 close to the first rotating tooth plate 105, and protective pads are fixedly installed on the outer walls of the opposite sides of the two clamping plates 107, and a first motor 109 is fixedly installed on the outer wall of one end of the mounting plate 103, and a driving gear 110 is fixedly sleeved on the output end of the first motor 109, and the driving gear 110 is meshed with the first rotating tooth plate 105, and the fixed groove 104 can limit the rotation of the first rotating tooth plate 105, and the movable groove 106 can limit the movement of the clamping plate 107, so that the clamping plate 107 can stably clamp the special-shaped component.

[0037] In order to keep the movable plate 205 stable during the height adjustment process, Figure 1 and Figure 4-5 As shown, the spraying mechanism 2 includes a limiting groove 202, and two limiting grooves 202 are provided. The two limiting grooves 202 are respectively opened on the inner walls of the two movable frames 201, and movable seats 204 are fixedly installed on the outer walls on both sides of the movable plate 205. The tops of the two movable seats 204 are respectively fixedly connected to the output ends of the two third hydraulic cylinders 203, and the outer walls of the two movable seats 204 are respectively movably connected to the inner walls of the two limiting grooves 202. The limiting grooves 202 can limit the movement of the movable seat 204, so that the movable plate 205 remains stable during the height adjustment process.

[0038] In order to conveniently detect the coating thickness of the outer wall of special-shaped components, Figure 4-5As shown, a placement groove 206 is opened on the inner wall of the movable plate 205, and the inner wall of the placement groove 206 is rotatably connected to the outer wall of the second rotating tooth plate 207. A detection probe 213 is fixedly installed on the inner wall of one side of the second rotating tooth plate 207. The placement groove 206 can install and limit the second rotating tooth plate 207, and the second rotating tooth plate 207 can install and fix the detection probe 213. The terminal control system can control the operation of the detection probe 213, and the thickness of the outer wall coating of the special-shaped component can be detected through the detection probe 213.

[0039] In order to enable the spray head 208 to stably spray different positions of the same area of ​​the special-shaped component, such as Figure 4-5 As shown, a second motor 211 is fixedly installed on one side of the top of the movable plate 205, and a rotating gear 212 is fixedly sleeved on the output end of the second motor 211, and the rotating gear 212 is meshed with the second rotating tooth plate 207. A storage barrel 209 is fixedly installed on the outer wall of one side of one movable frame 201, and a telescopic hose 210 fixedly connected to the top of the nozzle 208 is fixedly installed on the inner wall of the storage barrel 209. The second motor 211 can adjust the horizontal position of the nozzle 208 through the meshing action between the rotating gear 212 and the second rotating tooth plate 207. The telescopic hose 210 can stably transport the paint inside the storage barrel 209 to the nozzle 208. The spraying mode is set to air spraying. The gas can be transported from the inside of the storage barrel 209 to the telescopic hose 210 through the spraying auxiliary device, so that the nozzle 208 can perform air spraying operation.

[0040] When spraying large-sized special-shaped components, the positions of the two clamping mechanisms 1 can be adjusted through the terminal control system so that they can be moved through the bottom wheel group. Then, the two first hydraulic cylinders 102 included in one of the clamping mechanisms 1 can work to adjust the height of the mounting plate 103, and then the height of the clamping plate 107 can be adjusted so that the clamping plate 107 can be at the same height as the two ends of the special-shaped component. Then, the distance between the two clamping plates 107 can be adjusted through the work of the two second hydraulic cylinders 108, so that the two clamping plates 107 can clamp the outer wall of one end of the special-shaped component, and the protective pad on the outer wall of the clamping plate 107 can play a protective role. Similarly, the other clamping mechanism 1 can work to clamp and fix the other end of the special-shaped component.

[0041] The spraying mechanism 2 can be moved to the outside of the special-shaped component through terminal control, and the two third hydraulic cylinders 203 can drive the two movable seats 204 to move along the inner walls of the two limiting grooves 202, so that the movable plate 205 can move on the inner sides of the two movable frames 201, so that the height of the spray head 208 can be adjusted, and the paint inside the storage barrel 209 is transported to the spray head 208 through the telescopic hose 210, and then the spray head 208 can be used to spray the outer wall of the special-shaped component. At the same time, the second motor 211 can drive the spray head 208 to rotate in the horizontal direction through the meshing action between the rotating gear 212 and the second rotating tooth plate 207, so that it can spray different positions of the same area of ​​the outer wall of the special-shaped component;

[0042] At the same time, the detection probe 213 can detect the thickness of the coating, which can facilitate the repair of some uneven thickness positions. During the spraying process, the two heating plates 215 can heat the coating and improve the efficiency of coating curing. At the same time, the two first motors 109 can drive the clamping plate 107 to rotate through the meshing action between the active gear 110 and the first rotating tooth plate 105, and then drive the special-shaped component to rotate, so that the nozzle 208 can spray different positions of the outer wall of the special-shaped component. The spraying mechanism 2 is moved on the outside of the special-shaped component, so that it can conveniently spray different positions of the outer wall of the special-shaped component, which can improve the efficiency of spraying the special-shaped component. This embodiment specifically solves the problem that the prior art cannot be conveniently adjusted according to the size of the special-shaped component and the coating thickness cannot be detected, which will affect the spraying efficiency of the special-shaped component.

[0043] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
