Description

Technical Field

[0001] This utility model relates to the field of wind turbine blade manufacturing technology, and in particular to a coating spraying structure for wind turbine blades. Background Technology

[0002] Wind power generation refers to converting the kinetic energy of wind into electrical energy. Utilizing wind power is very environmentally friendly, and wind energy reserves are enormous, thus attracting increasing attention from countries worldwide. A wind turbine mainly consists of a wind turbine and a generator. A key component of the wind turbine is the blade, and the corrosion resistance of the blade plays a decisive role in the service life of the wind turbine. Therefore, during the production of the blades, it is necessary to apply an anti-corrosion coating.

[0003] However, the existing coating structures for wind turbine blades have shortcomings. Generally, it is necessary to fix the wind turbine blade with a clamp and then spray the top of the blade. After the top surface is sprayed, the blade is removed and fixed for another surface. This makes it difficult to spray the entire wind turbine blade and reduces the efficiency of the spraying. Therefore, we propose a coating structure for wind turbine blades to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned shortcomings and propose a coating spraying structure for wind turbine blades.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A coating structure for wind turbine blades includes a base, a mounting frame fixedly connected to the top of the base, a coating mechanism for coating the wind turbine blades, a clamping and rotating mechanism for clamping and rotating the wind turbine blades, and a reciprocating motion mechanism for reciprocating left and right movements of the coating mechanism. The coating mechanism includes a material pump and a coating tank fixedly connected to the top of the mounting frame. The material pump and the bottom of the coating tank are connected to one side. A hose is fixedly connected to the bottom of the material pump. A spraying disc is fixedly connected to the bottom of the hose. A plurality of spray nozzles are fixedly connected to the bottom of the spraying disc. A recycling box is fixedly connected to the top of the base. A discharge pipe is fixedly connected to the bottom of one side of the recycling box.

[0007] As a preferred embodiment of this utility model, the clamping and rotating mechanism includes a rotary motor fixedly connected to one side of the mounting frame, and two rotating shafts. The two rotating shafts are respectively rotatably connected to both sides of the mounting frame. The output shaft of the rotary motor is fixedly connected to one end of the corresponding rotating shaft. The ends of the two rotating shafts that are close to each other are fixedly connected to a fixing plate. The fixing plate is provided with a clamping component for clamping and fixing the wind turbine blades.

[0008] As a preferred embodiment of this invention, the two rotating shafts are rotatably connected to both sides of the mounting bracket via bearings.

[0009] As a preferred embodiment of this utility model, the clamping assembly includes a slide groove formed on one side of the fixed plate. The same bidirectional lead screw is rotatably connected to the inner walls of the front and rear sides of the slide groove. Two drive plates are threaded on the outer side of the bidirectional lead screw. A clamping plate is fixedly connected to one side of each of the two drive plates. An anti-slip rubber pad is fixedly connected to the side of each clamping plate that is close to each other.

[0010] As a preferred embodiment of this utility model, one end of the bidirectional lead screw is fixedly connected to a knob, and both drive plates are slidably sleeved in the slide groove.

[0011] In a preferred embodiment of this invention, the reciprocating motion mechanism includes a worm gear fixedly connected to one end of a rotating shaft on the left side, a worm wheel rotatably connected to one side of a mounting frame, and a connecting rod fixedly connected to one side of a spraying disc. The worm gear meshes with the worm wheel. A drive column is fixedly connected to the front side of the worm wheel. A movable frame is slidably sleeved on the outer side of the drive column. A movable plate is fixedly connected to the rear side of the movable frame. The connecting rod is fixedly connected to one side of the movable plate. A spring is fixedly connected between the mounting frame and the movable plate. A guide rod is fixedly connected to one side of the mounting frame. The movable plate is slidably sleeved on the outer side of the guide rod.

[0012] As a preferred embodiment of this invention, a stabilizing plate is rotatably connected to the rear side of the worm gear, and the stabilizing plate is fixedly connected to one side of the mounting bracket.

[0013] As a preferred embodiment of this utility model, two guide frames are fixedly connected to the top inner wall of the mounting bracket, and sliding plates are slidably sleeved on the outer side of the guide frames. Both sliding plates are fixedly connected to the top of the spraying disc.

[0014] In this utility model, a coating spraying structure for wind turbine blades is described. The wind turbine blade is placed between two fixed plates. Two double-acting screws are rotated by two knobs. The double-acting screws drive two drive plates, clamping plates, and anti-slip rubber pads to move closer together, thereby clamping and fixing the wind turbine blade between the two fixed plates and the rotating shaft. A material pump draws the coating into a hose and spraying disc, and finally sprays it out from multiple nozzles to coat the wind turbine blade. At the same time, a rotating motor drives the two rotating shafts and the wind turbine blade to rotate, so that the blade can be rotated while being sprayed, without the need for changing sides. This not only improves the efficiency of spraying, but also improves the uniformity and comprehensiveness of the spraying.

[0015] In this utility model, a coating spraying structure for wind turbine blades is described. The rotating shaft on the left side drives the rotation of the worm gear, which in turn drives the rotation of the worm wheel and the drive column. The drive column slides within the moving frame and drives the moving frame, the moving plate, and the connecting rod to reciprocate left and right. The connecting rod drives the spraying disc to reciprocate left and right. Because there are gaps between the nozzles, the coating cannot be evenly and comprehensively sprayed onto the wind turbine blades. However, the reciprocating left and right movement of the spraying disc and nozzles can greatly improve the uniformity and comprehensiveness of the spraying, resulting in a better spraying effect. Excess coating flows into the recycling box and can be discharged from the discharge pipe for collection and reuse.

[0016] This utility model has a reasonable structural design. The clamping and rotating mechanism facilitates the clamping and fixing of wind turbine blades and drives the blades to rotate. While spraying and rotating, there is no need to change sides, which not only improves the efficiency of spraying, but also improves the uniformity and comprehensiveness of the spraying. The left and right reciprocating motion mechanism drives the spraying disc and the nozzle to reciprocate left and right, further improving the uniformity and comprehensiveness of the spraying, resulting in a better spraying effect.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Reference Figures 1-4 A coating spraying structure for wind turbine blades includes a base 1, a mounting frame 2 fixedly connected to the top of the base 1, a spraying mechanism for spraying wind turbine blades, a clamping and rotating mechanism 3 for clamping and rotating wind turbine blades, and a left-right reciprocating motion mechanism 8 for reciprocating left-right motion of the spraying mechanism. The spraying mechanism includes a material pump 5 and a paint tank 4 fixedly connected to the top of the mounting frame 2. The bottom of one side of the material pump 5 and the paint tank 4 are connected. A hose 9 is fixedly connected to the bottom of the material pump 5. A spraying disc 10 is fixedly connected to the bottom of the hose 9. A plurality of nozzles 11 are fixedly connected to the bottom of the spraying disc 10. A recycling box 6 is fixedly connected to the top of the base 1. A discharge pipe 7 is fixedly connected to the bottom of one side of the recycling box 6.

[0024] Furthermore, refer to Figure 1 , Figure 2 and Figure 4 The clamping and rotating mechanism 3 includes a rotary motor 32 fixedly connected to one side of the mounting frame 2, and two rotating shafts 33. The two rotating shafts 33 are respectively rotatably connected to both sides of the mounting frame 2. The output shaft of the rotary motor 32 is fixedly connected to one end of the corresponding rotating shaft 33. The ends of the two rotating shafts 33 that are close to each other are fixedly connected to a fixing plate 31. The fixing plate 31 is provided with a clamping assembly 310 for clamping and fixing the wind turbine blades. The two rotating shafts 33 are respectively rotatably connected to both sides of the mounting frame 2 through bearings.

[0025] The above scheme is adopted: the material pump 5 can draw the paint into the hose 9 and the spray plate 10, and finally spray it out from multiple nozzles 11 to spray the wind turbine blades. At the same time, the rotating motor 32 drives the two rotating shafts 33 and the wind turbine blades to rotate, so that the rotation can be carried out while spraying, without the need to change the side, which not only improves the efficiency of spraying, but also improves the uniformity and comprehensiveness of spraying.

[0026] Furthermore, refer to Figure 1 , Figure 2 and Figure 4 The clamping assembly 310 includes a slide groove 313 formed on one side of the fixed plate 31. The same bidirectional lead screw 312 is rotatably connected to the inner walls of the front and rear sides of the slide groove 313. Two drive plates 315 are threaded on the outer side of the bidirectional lead screw 312. A clamping plate 314 is fixedly connected to one side of each of the two drive plates 315. Anti-slip rubber pads 316 are fixedly connected to the sides of the two clamping plates 314 that are close to each other.

[0027] Using the above solution: the wind turbine blade is placed between two fixed plates 31, and two double-acting screws 312 are rotated by two knobs 311. The double-acting screws 312 drive the two drive plates 315, clamping plates 314 and anti-slip rubber pads 316 to move closer to each other, thereby clamping and fixing the wind turbine blade between the two fixed plates 31 and the rotating shaft 33.

[0028] Furthermore, a knob 311 is fixedly connected to one end of the bidirectional lead screw 312, and two drive plates 315 are slidably sleeved in the slide groove 313, which facilitates the rotation of the bidirectional lead screw 312 and at the same time guides and limits the drive plates 315 so that they do not rotate together with the bidirectional lead screw 312.

[0029] Furthermore, refer to Figure 2 and Figure 3 The reciprocating motion mechanism 8 includes a worm 84 fixedly connected to one end of the rotating shaft 33 on the left side, a worm wheel 86 rotatably connected to one side of the mounting frame 2, and a connecting rod 87 fixedly connected to one side of the spraying disc 10. The worm 84 meshes with the worm wheel 86. A drive column 85 is fixedly connected to the front side of the worm wheel 86. A movable frame 89 is slidably sleeved on the outer side of the drive column 85. A movable plate 82 is fixedly connected to the rear side of the movable frame 89. The connecting rod 87 is fixedly connected to one side of the movable plate 82. A spring 88 is fixedly connected between the mounting frame 2 and the movable plate 82. A guide rod 81 is fixedly connected to one side of the mounting frame 2. The movable plate 82 is slidably sleeved on the outer side of the guide rod 81.

[0030] Using the above scheme: the left-side rotating shaft 33 drives the rotation of the worm gear 84, which in turn drives the rotation of the worm wheel 86 and the drive column 85. The drive column 85 slides within the moving frame 89 and drives the moving frame 89, the moving plate 82, and the connecting rod 87 to reciprocate left and right. The connecting rod 87 drives the spraying disc 10 to reciprocate left and right. Because there are gaps between the nozzles 11, the paint from the nozzles may not be evenly and comprehensively sprayed onto the wind turbine blades. However, the reciprocating left and right movement of the spraying disc 10 and the nozzles 11 can greatly improve the uniformity and comprehensiveness of the spraying, resulting in a better spraying effect.

[0031] Furthermore, a stabilizing plate 83 is rotatably connected to the rear side of the worm gear 86. The stabilizing plate 83 is fixedly connected to one side of the mounting bracket 2 to facilitate support for the worm gear 86 and make its rotation more stable.

[0032] Furthermore, two guide frames 13 are fixedly connected to the top inner wall of the mounting bracket 2. Sliding plates 12 are slidably sleeved on the outer side of the guide frames 13. Both sliding plates 12 are fixedly connected to the top of the spraying disc 10, which helps to guide the spraying disc 10 and make its lateral movement more stable.

[0033] In this invention, during use, the wind turbine blade is placed between two fixed plates 31. Two knobs 311 rotate two bidirectional lead screws 312, which in turn drive two drive plates 315, clamping plates 314, and anti-slip rubber pads 316 closer together. This clamps and fixes the wind turbine blade between the two fixed plates 31 and the rotating shaft 33. A material pump 5 draws paint into the hose 9 and spray disc 10, which is then sprayed from multiple nozzles 11 to coat the wind turbine blade. Simultaneously, a rotating motor 32 drives the two rotating shafts 33 and the wind turbine blade to rotate, allowing for simultaneous spraying and rotation without the need for changing sides. This not only improves spraying efficiency but also enhances the overall spraying performance. The coating is uniform and comprehensive. Meanwhile, the rotating shaft 33 on the left side drives the rotation of the worm gear 84, which in turn drives the rotation of the worm wheel 86 and the drive column 85. The drive column 85 slides within the moving frame 89 and drives the moving frame 89, the moving plate 82, and the connecting rod 87 to reciprocate left and right. The connecting rod 87 drives the spraying disc 10 to reciprocate left and right. Because there are gaps between the nozzles 11, the paint from the nozzles may not be able to be sprayed evenly and comprehensively onto the wind turbine blades. However, the reciprocating left and right motion of the spraying disc 10 and the nozzles 11 can greatly improve the uniformity and comprehensiveness of the spraying, resulting in a better spraying effect. Excess paint flows into the recycling box 6 and can be discharged from the discharge pipe 7 for collection and reuse.
