Description

Technical Field

[0001] This utility model relates to the field of wind turbine tower installation technology, specifically to an automatic spraying device for wind turbine towers. Background Technology

[0002] For example, a variable automatic spraying device for wind turbine towers, disclosed in patent publication number CN215964338U, includes a housing. A movable arm is mounted on the top of the housing, and a base is fixed to the bottom of the movable arm. A rotating seat is positioned between the base and the housing, with its bottom fixedly connected to the top of the housing. Multiple mounting holes are provided between the top of the rotating seat and the bottom of the base, with bolts passing through the inner sides of the mounting holes. A groove is symmetrically provided on the top of the rotating seat, and a limiting block is provided inside the groove. A connecting spring connects the bottom of the limiting block to the groove. Through the designed limiting block, groove, and connecting spring, the original method of manually aligning the mounting holes between the base and the rotating seat during installation is improved. This structure allows for automatic alignment of the mounting holes between the base and the rotating seat during installation, thereby increasing installation efficiency.

[0003] However, during the use of the above-mentioned equipment, due to the design of its internal movable arm, and because the tower is generally circular, it needs to be rotated and adjusted in position after spraying before spraying can continue, which can easily lead to uneven spraying and reduce work efficiency. Therefore, we propose a more convenient and practical automatic spraying device to meet the usage requirements. Utility Model Content

[0004] The purpose of this invention is to provide an automatic spraying device for wind turbine towers to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic spraying device for wind turbine towers, comprising a base, a rotating mechanism for supporting the tower on one side of the top of the base, the rotating mechanism including a base plate connected to the base, a slot in the center of the top of the base plate, a sliding plate slidably connected in the slot, a through hole in the center of one side of the base plate, a bidirectional screw rotatably connected in the through hole, the two ends of the bidirectional screw being threadedly connected to the sliding plate, a rotating assembly on one side of the sliding plate, and a spraying mechanism on the top of the base away from the rotating mechanism.

[0006] Furthermore, the rotating assembly includes a rotating shaft, which is rotatably connected to a sliding plate. One end of the rotating shaft is fixedly connected to a first gear, and the other end is fixedly connected to a cross-shaped rotating plate. A second gear is rotatably connected to one side of the bottom of the sliding plate, and the teeth of the second gear and the first gear mesh with each other.

[0007] Furthermore, a slot is provided on one side of the rotating plate, and a sliding block is slidably connected in the slot. A through hole is provided on one side of the rotating plate, and a lead screw is rotatably connected in the through hole. The lead screw and the sliding block are threaded together.

[0008] Furthermore, the spraying mechanism includes symmetrically arranged linear slide rails, which are connected to the base. A linear slider is slidably connected to the top of the linear slide rails, and a mounting plate is fixedly connected to the top of the linear slider.

[0009] Furthermore, a support plate is fixedly connected to one side of the top of the mounting plate, and a spray box is fixedly connected to the other side.

[0010] Furthermore, a through hole is provided on one side of the top of the support plate, and a spray pipe is installed in the through hole. One end of the spray pipe is fixedly connected to a nozzle, and the other end is equipped with a booster pump. The booster pump is connected to the spray box.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This automatic wind turbine tower spraying device, through the setup of a rotating mechanism and a spraying mechanism, firstly hoists the tower onto the base plate. Then, the motor drives a bidirectional screw to rotate, causing a sliding plate to move a rubber support pad. Next, the motor drives a lead screw to rotate, causing a sliding block to move the rubber support pad along the rotating plate, supporting the tower from the inner wall. Finally, when the tower angle needs to be adjusted, the motor drives a second gear to rotate, which in turn drives the first gear and the rotating shaft to rotate, thereby adjusting the tower angle. This device can ensure that all parts of the tower surface are sprayed evenly, avoiding missed spraying or repeated spraying. It is highly practical and suitable for widespread application.

[0013] Meanwhile, the spraying mechanism can be precisely adjusted in lateral position along the slide rail to ensure that the nozzle is always aligned with the tower surface, avoiding uneven spraying caused by misalignment. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] In the production process of wind turbine towers, spraying equipment is required. The spraying equipment provided by this utility model is specifically designed for tower spraying operations during the production of wind turbine towers. When using this equipment for spraying operations, the spraying operation should be carried out in a dry and well-ventilated environment. Avoid using it in a humid or confined environment to prevent affecting the spraying effect and paint drying speed. At the same time, ensure that there are no flammable or explosive materials around the spraying area to ensure operational safety. During the spraying process, the nozzle 307 should be moved evenly and stably to ensure that the paint can be evenly covered on the surface of the tower, avoiding over-spraying or missed spraying, so as not to affect the spraying effect and aesthetics.

[0020] like Figures 1-3 As shown, this utility model provides a technical solution: an automatic spraying device for wind turbine towers, including a base 1, a rotating mechanism 2 for supporting the tower on one side of the top of the base 1, the rotating mechanism 2 including a base plate 201, the base plate 201 and the base 1 being connected, a slot is provided in the center of the top of the base plate 201, a sliding plate 202 is slidably connected in the slot, a through hole is provided in the center of one side of the base plate 201, a bidirectional screw 203 is rotatably connected in the through hole, the two ends of the bidirectional screw 203 are threadedly connected to the sliding plate 202, a rotating component is provided on one side of the sliding plate 202, and a spraying mechanism 3 is provided on the top of the base 1 away from the rotating mechanism 2.

[0021] like Figure 2As shown, the rotating assembly includes a rotating shaft 204, which is rotatably connected to a sliding plate 202. A first gear 205 is fixedly connected to one end of the rotating shaft 204, and a cross-shaped rotating plate 206 is fixedly connected to the other end. A second gear 207 is rotatably connected to one side of the bottom of the sliding plate 202. The teeth of the second gear 207 and the first gear 205 mesh with each other. A slot is opened on one side of the rotating plate 206, and a sliding block 208 is slidably connected in the slot. A through hole is opened on one side of the rotating plate 206, and a lead screw 209 is rotatably connected in the through hole. The lead screw 209 and the sliding block 208 are threadedly connected. A rubber support pad 210 is fixedly connected to one side of the top of the sliding block 208.

[0022] It should be noted that during use, the tower is first hoisted and placed above the base plate 201. Then, the motor drives the bidirectional screw 203 to rotate, causing the sliding plate 202 to move the rubber support pad 210. Next, the motor drives the lead screw 209 to rotate, causing the sliding block 208 to move the rubber support pad 210 along the rotating plate 206 to support the tower from the inner wall. Finally, when the angle of the tower needs to be adjusted, the motor drives the second gear 207 to rotate, causing the first gear 205 and the rotating shaft 204 to rotate, thereby adjusting the angle of the tower. The rotating mechanism 2 can adapt to towers of different diameters without replacing parts, and has strong versatility.

[0023] like Figure 3 As shown, the spraying mechanism 3 includes symmetrically arranged linear slide rails 301, which are connected to the base 1. A linear slider 302 is slidably connected to the top of the linear slide rails 301, and a mounting plate 303 is fixedly connected to the top of the linear slider 302. A support plate 304 is fixedly connected to one side of the top of the mounting plate 303, and a spraying box 305 is fixedly connected to the other side. A through hole is opened on one side of the top of the support plate 304, and a spray pipe 306 is installed in the through hole. A nozzle 307 is fixedly connected to one end of the spray pipe 306, and a booster pump 308 is installed at the other end. The booster pump 308 is connected to the spraying box 305.

[0024] It should be noted that during use, firstly, the linear slider 302 slides on the linear slide rail 301 to adjust the position of the mounting plate 303. Then, the booster pump 308 is started and inputs through the spray pipe 306 to the spray nozzle 307 to spray the tower. It is supported by the support plate 304. The spraying mechanism 3 can be precisely adjusted in lateral position along the slide rail to ensure that the spray nozzle 307 is always aligned with the surface of the tower, avoiding uneven spraying caused by offset.

[0025] During use, the tower is first hoisted and placed above the base plate 201. Then, the motor drives the bidirectional screw 203 to rotate, causing the sliding plate 202 to move the rubber support pad 210. Next, the motor drives the lead screw 209 to rotate, causing the sliding block 208 to move the rubber support pad 210 along the rotating plate 206 to support the tower from the inner wall. At the same time, the linear slider 302 slides on the linear slide rail 301 to adjust the position of the mounting plate 303. Then, the booster pump 308 is started and inputs the spray through the spray pipe 306 to the spray nozzle 307 to spray the tower. Finally, when it is necessary to adjust the angle of the tower, the motor drives the second gear 207 to rotate, which in turn drives the first gear 205 and the rotating shaft 204 to rotate, thereby adjusting the angle of the tower. This device can ensure that all parts of the tower surface are sprayed evenly, avoiding missed spraying or repeated spraying.
