Description

Technical Field

[0001] The invention relates to the technical field of wind power device painting, and in particular to an automatic painting device for a wind power tower. Background Art

[0002] A wind turbine generator set includes a wind rotor, a generator and a wind tower. It can use the wind force passing through the wind rotor blades to generate aerodynamic force to drive the wind rotor to rotate, and then increase the speed of rotation through the speed increaser to enable the generator to generate electricity. The wind tower is a component that supports the wind rotor and the generator. Steel has the characteristics of high strength, good welding performance and easy processing, so steel is often used as the main material of the wind tower.

[0003] In order to protect the steel wind turbine tower from corrosion, paint is applied to its outer wall regularly. However, most wind turbine towers are erected outdoors, and the height of the wind turbine tower is relatively high, so the painting work needs to be done at high altitude. The risk factor is high and the work efficiency is relatively low for workers to climb to the wind turbine tower for painting. Now, automatic painting devices are mostly used for painting. The existing automatic painting device includes two semi-circular fixed frames, on which a painting mechanism and an automatic climbing mechanism are arranged, and the painting mechanism can spray paint on the outer wall of the wind turbine tower. The automatic climbing mechanism enables the painting device to climb along the wind turbine tower and change the height position of the painting. However, since the wind turbine tower is set outdoors for a long time and is affected by the air environment, floating rust will form on the outer wall of the wind turbine tower. Direct painting will cause the paint surface to bubble and peel off, and the painting effect is poor, which has a poor anti-corrosion protection effect on the wind turbine tower. Summary of the invention

[0004] In view of this, the present invention provides an automatic painting device for a wind turbine tower to solve the problem that the existing automatic painting device for painting the wind turbine tower will lead to poor painting effect due to floating rust on the outer wall of the wind turbine tower, and the anti-corrosion protection effect of the wind turbine tower is poor.

[0050] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0051] Combine the following Figures 1 to 6 , describing an embodiment of the present invention.

[0052] According to an embodiment of the present invention, on the one hand, an automatic painting device for a wind turbine tower is provided, and the automatic painting device for a wind turbine tower comprises: a mounting shell 1, a rust removal component 2, a climbing component 3 and a painting component 4. An installation channel is provided in the middle of the mounting shell 1. The rust removal component 2 is provided in the mounting shell 1. A plurality of groups of climbing components 3 are arranged on the inner wall of the mounting shell 1 at intervals along the circumference of the mounting shell 1, and one end of the climbing component 3 abuts against the wind turbine tower provided in the mounting channel. The painting component 4 is provided in the mounting shell 1 and is located below the rust removal component 2.

[0053] like Figure 1 As shown, the mounting shell 1 is cylindrical as a whole, and the middle of the mounting shell 1 is a mounting channel. When the automatic painting device of the wind power tower is used, the mounting shell 1 is sleeved on the wind power tower, which is equivalent to the wind power tower being located in the mounting channel. The rust removal component 2, the climbing component 3 and the painting component 4 are all arranged on the mounting shell 1. In this embodiment, the rust removal component 2, the climbing component 3 and the painting component 4 are arranged in sequence from top to bottom, wherein the rust removal component 2 is mainly used to remove the floating rust on the wind power tower, so as to facilitate the subsequent painting work of the painting component 4. Multiple groups of climbing mechanisms 33 are abutted from different positions on the periphery of the wind power tower to ensure that the automatic painting device is firmly fixed on the wind power tower, and can drive the automatic painting device to climb to gradually remove rust and spray paint on the entire wind power tower.

[0054] The rust removal component 2 can be provided to remove the floating rust on the wind power tower before painting, so that the paint spraying component 4 can be effectively sprayed on the outer wall of the wind power tower during the subsequent painting, forming a complete and stable paint surface on the outer wall, with a better painting effect and a better final anti-corrosion protection effect. Moreover, the rust removal component 2 is above the paint spraying component 4, and the process of rust removal first and then painting can be carried out, and the layout is more reasonable.

[0055] In other embodiments, the rust removal component 2, the paint spraying component 4 and the climbing component 3 may be arranged in sequence from top to bottom.

[0056] In some embodiments, the mounting shell 1 includes two shells 12, which are connected by a connecting assembly 6. The connecting assembly 6 includes: a connecting seat 61, a connecting block 62 and a connecting piece 63. The connecting seat 61 is arranged on the outer wall of one of the shells 12, and the connecting block 62 is arranged on the outer wall of the other shell 12. The connecting seat 61 and the connecting block 62 are connected by the connecting piece 63.

[0057] The installation shell 1 is composed of two identical shells 12 connected together, and the cross-sectional shape of each shell 12 is approximately semi-circular. Making the installation shell 1 into a split type is more convenient for use. During operation, it can be directly sleeved on the outer side of the wind power tower, and then connected and fixed through the connection assembly 6. Of course, in other embodiments, the installation shell 1 can also be formed by connecting three, four or other numbers of shells 12 to each other.

[0058] Further, as Figure 2 shown, in this embodiment, the two shells 12 are connected by four groups of connection assemblies 6. Two connection seats 61 are provided at one connection end of each shell 12, and two connection blocks 62 are provided at the other connection end. The connection seat 61 is in an "n" shape, the connection block 62 is in an "L" shape, and the connecting member 63 is a bolt and a nut. Insert the connection block 62 between the connection seats 61, then set the bolt in the corresponding holes of the connection block 62 and the connection seat 61, and finally tighten the nut to complete the connection. The connection of the shells 12 can be realized quickly through the connection assembly 6, and the connection is firm and reliable.

[0059] In other embodiments, the connection seats 61 and the connection blocks 62 can both be in an "n" shape and be inserted into each other, or both be in an "L" shape for connection, and the connecting member 63 can also be a connecting pin, etc.

[0060] In other embodiments, the number of the connection assemblies 6 can be adaptively selected according to the size of the shell 12, and no specific limitation is made in this embodiment.

[0061] In some embodiments, the rust removal assembly 2 includes: a rust removal mechanism 21 and a rotation mechanism 22. A circular chute 11 is provided on the top surface of the installation shell 1. The rust removal mechanism 21 is arranged in the chute 11, and the rotation mechanism 22 is connected to the rust removal mechanism 21. The rotation mechanism 22 is used to drive the rust removal mechanism 21 to move in the chute 11.

[0062] The installation shell 1 is formed by connecting two shells 12. Correspondingly, a semi-circular groove is provided on the top surface of each shell 12, and the two semi-circular grooves are connected into a circular chute 11. The rotation mechanism 22 is used to drive the rust removal mechanism 21 to rotate so as to rust-remove the entire wind power tower in all directions.

[0063] In one embodiment, the rust removal mechanism 21 includes: a moving seat 211, an adjusting seat 212 and a rust removal member 213. The moving seat 211 is arranged in the chute 11, the adjusting seat 212 is arranged on the moving seat 211, and the rust removal member 213 is arranged on the adjusting seat 212.

[0064] As Figure 2 、 Figure 3As shown, the bottom end of the movable seat 211 is located in the slide groove 11, and the mounting end of the movable seat 211 will extend to the mounting channel. The sliding of the movable seat 211 in the slide groove 11 can drive the entire rust removal mechanism 21 to move. The adjustment seat 212 includes: a rotary adjustment bracket 2121 and a pitch angle adjustment bracket 2122, and the rust removal member 213 is arranged on the pitch angle adjustment bracket 2122. The rotary adjustment bracket 2121 can drive the rust removal member 213 to rotate in the horizontal direction, and the pitch angle adjustment bracket 2122 can adjust the elevation angle of the rust removal member 213. This adjustment seat 212 can adjust the working position of the rust removal member 213 to achieve a better rust removal effect. The rust removal member 213 is an arc-shaped plate, which is similar to the outer wall of the wind power tower. There are multiple scraping strips on the arc-shaped plate to scrape off the floating rust.

[0065] Specifically, in the present embodiment, two groups of rust removal mechanisms 21 are provided, and the two groups of rust removal mechanisms 21 can work simultaneously to improve work efficiency. Of course, in other embodiments, the rust removal mechanisms 21 can also be provided in one group, three groups or more.

[0066] In one embodiment, the rotating mechanism 22 includes: a rack 221, a gear 222 and a first driving member 223, the rack 221 is arranged on the inner wall of the mounting shell 1, the first driving member 223 is arranged on the moving seat 211, and its driving end is connected to the gear 222, and the gear 222 is meshed with the rack 221.

[0067] The rack 221 is annularly arranged on the inner wall of the mounting shell 1, and the toothed structure on the rack 221 meshes with the gear 222. The first driving member 223 is preferably a motor, which is arranged at the mounting end of the moving seat 211. The output shaft of the motor is connected to the gear 222. When the motor rotates, the gear 222 can be driven to rotate, and then the rust removal mechanism 21 can be driven to rotate around the rack 221.

[0068] Furthermore, the rust removal assembly 2 also includes a first collecting groove 23, which is also in a semicircular shape. A slot is provided on each housing 12, and a block is provided on the outer edge of the first collecting groove 23, which can slide into the slot from one end of the housing 12 to achieve position fixing. The first collecting groove 23 is located below the rust removal mechanism 21 and the rotating mechanism 22, and is used to collect the floating rust scraped off by the rust removal mechanism 21 when it is working, so as to prevent the floating rust from falling on other positions of the automatic painting device or falling on the ground.

[0069] In some embodiments, the climbing assembly 3 includes: a mounting seat 31, a variable diameter adjustment mechanism 32 and a climbing mechanism 33. The mounting seat 31 is arranged on the inner wall of the mounting shell 1, and a group of variable diameter adjustment mechanisms 32 are respectively arranged on the top and bottom of the mounting seat 31. The variable diameter adjustment mechanism 32 is provided with a climbing mechanism 33, and the climbing mechanism 33 abuts against the outer wall of the wind turbine tower.

[0070] The climbing mechanism 33 can maintain the connection between the automatic painting device and the wind power tower, and can also drive the entire automatic painting device to climb along the wind power tower to remove rust and spray paint at various positions of the wind power tower. The variable diameter adjustment mechanism 32 can change the distance between the mounting seat 31 and the climbing mechanism 33, so that the automatic painting device can be applied to wind power towers with variable diameters.

[0071] In one embodiment, the variable diameter adjustment mechanism 32 includes: a first rotating device 321 and a bracket 322, the first rotating device 321 is disposed on the mounting seat 31, and one end of the bracket 322 is connected to the first rotating device 321;

[0072] like Figure 4 As shown, the first rotating device 321 can be selected as a motor, which is arranged on the mounting seat 31 and connected to one end of the bracket 322. When the motor is started, the bracket 322 can be driven to rotate, thereby changing the angle between the bracket 322 and the wind power tower. The variable diameter wind power tower generally has a large bottom diameter and a small top diameter. When the automatic painting device climbs upward, the first rotating device 321 will drive the bracket 322 to rotate, so that the angle between the upper and lower brackets 322 becomes smaller and smaller. Conversely, when the automatic painting device moves downward and returns to the ground, the first rotating device 321 will drive the bracket 322 to rotate, so that the angle between the upper and lower brackets 322 becomes larger and larger.

[0073] When the automatic painting device is actually working, it will not only encounter wind turbine towers with unchanged diameters, but also a large number of wind turbine towers with variable diameters. By setting the variable diameter adjustment mechanism 32, the use of various wind turbine towers can be met, and the application range of the automatic painting device is wider.

[0074] In one embodiment, the climbing mechanism 33 includes: a second rotating device 331 and a climbing wheel 332 , the second rotating device 331 is connected to the other end of the bracket 322 , and the climbing wheel 332 is connected to the second rotating device 331 .

[0075] like Figure 4 As shown, the second rotating device 331 can select a motor like the first rotating device 321, and the motor is arranged at one end of the bracket 322 away from the mounting seat 31. The second rotating device 331 can drive the climbing wheel 332 to rotate when it is started, so as to move up or down on the wind power tower.

[0076] Furthermore, a sensing probe 34 is provided on the mounting base 31, and the sensing probe 34 is electrically connected to the variable diameter adjustment mechanism 32 and the climbing mechanism 33 to realize the control of the first rotating device 321 and the second rotating device 331. The sensing probe 34 issues instructions to control the variable diameter adjustment mechanism 32 and the climbing mechanism 33 according to the diameter change of the wind power tower, and drives the automatic painting device to climb and change the working position.

[0077] In some embodiments, the paint spraying assembly 4 includes: a paint storage bin 41 and a plurality of paint spraying mechanisms 42 , the paint storage bin 41 is arranged on the outer wall of the mounting shell 1 , and the plurality of paint spraying mechanisms 42 are arranged on the inner wall of the mounting shell 1 at intervals along the circumference of the mounting shell 1 .

[0078] A plurality of paint spraying mechanisms 42 are used to spray paint on the wind power tower from various angles. The paint storage bin 41 is arranged on the outer wall of the mounting shell 1 , and a paint spraying pump 44 is arranged on the paint storage bin 41 , through which paint is pumped to the paint spraying mechanism 42 .

[0079] In one embodiment, the paint spraying mechanism 42 includes: a base 421, an adjusting mechanism and a nozzle 423. The base 421 is arranged on the inner wall of the mounting shell 1. The adjusting mechanism includes: a second driving member 4221, a threaded shaft 4222 and a connecting plate 4223. The second driving member 4221 is arranged on the base 421, and its output end is connected to the threaded shaft 4222, and the threaded shaft 4222 is arranged along the axial direction of the mounting shell 1. The connecting plate 4223 is threadedly connected to the threaded shaft 4222. The nozzle 423 is arranged on the connecting plate 4223 and is connected to the paint storage bin 41 through the paint supply pipe 43.

[0080] like Figure 5 , Figure 6 As shown, the base 421 is plate-shaped and fixedly arranged on the inner wall of the mounting shell 1. A mounting groove is provided in the middle of the base 421, and the threaded shaft 4222 is arranged in the mounting groove. The second driving member 4221 is preferably a motor, which is arranged on the top of the mounting seat 31, and the motor is connected to the threaded shaft 4222 to drive the threaded shaft 4222 to rotate. The connecting plate 4223 has a connecting portion on the side facing the base 421, and a threaded hole is provided on the connecting portion, and the connecting portion is threadedly connected to the threaded shaft 4222 through the threaded hole. In this way, when the second driving member 4221 is started, the connecting plate 4223 can be driven to move up and down. The spray head 423 is arranged on the connecting plate 4223 and can move up and down with the connecting plate 4223. The anti-corrosion paint in the paint storage bin 41 is supplied to the spray head 423 through the paint supply pipe 43, and the spray head 423 sprays paint on the wind power tower. Since the spray head 423 can move up and down, it has a larger working range for spraying paint, so the number of times the automatic spraying device moves as a whole can be reduced.

[0081] In another embodiment, two mounting plates 4224 are further arranged on the connecting plate 4223, and the two mounting plates 4224 are arranged at intervals up and down. The rotating member 4225 is arranged on the mounting plate 4224, and the spray head 423 is arranged on the rotating member 4225. In this way, the spray head 423 can not only move up and down with the connecting plate 4223, but also rotate, with more spraying angles, a larger and more comprehensive working range.

[0082] Furthermore, the paint spraying assembly 4 further includes a second collecting tank 45, which has the same structure as the first collecting tank 23 and is connected to the housing 12 in the same manner as the first collecting tank 23. The second collecting tank 45 is disposed below the paint spraying mechanism 42 and is used to collect scattered anticorrosive paint.

[0083] In some embodiments, the automatic painting device for a wind turbine tower further includes a braking assembly 5, which includes: a plurality of height detection devices 51 and a braking mechanism 52 alternately arranged on the inner wall of the mounting shell 1, the braking mechanism 52 includes: a hydraulic driving component 521, a braking plate 522 and a friction strip 523, the hydraulic driving component 521 is arranged on the inner wall of the mounting shell 1, and a braking plate 522 is arranged at its driving end, and a friction strip 523 is arranged on the braking plate 522.

[0084] The brake assembly 5 is located at the bottom of the mounting seat 31, that is, below the paint spraying assembly 4. A height detection device 51 and a set of brake mechanisms 52 are alternately arranged around the inner wall of the mounting seat 31. When the automatic painting device fails and falls, the height detection device 51 detects the height drop of the automatic painting device and controls the brake mechanism 52 to start, thereby limiting the position of the automatic painting device through the brake mechanism 52 so that it does not continue to fall.

[0085] Further, such as Figure 7 As shown, the brake mechanism 52 adopts a hydraulic drive component 521, i.e., a hydraulic cylinder, to drive the brake plate 522 to extend and retract. When braking is required, the hydraulic drive component 521 drives the brake plate 522 to extend, so that the friction strip 523 on the brake plate 522 rubs against the outer wall of the wind power tower, so that the automatic painting device slows down until it stops falling.

[0086] The safety of the automatic painting device is improved by providing the brake assembly 5. When some unexpected situations occur, the brakes can be quickly applied to prevent the automatic painting device from falling to the ground and causing safety accidents.

[0087] The working process of the automatic painting device for wind power tower provided in this embodiment is described as follows:

[0088] First, the automatic painting device is installed: the two shells 12 are mounted on the wind power tower, and the two shells 12 are connected through the connecting assembly 6 , that is, the connecting seat 61 and the connecting block 62 are connected together through the connecting piece 63 .

[0089] Then, the rust removal work is performed, the first driving member 223 is started, the gear 222 is driven to rotate, and then the movable seat 211 is driven to slide in the slide slot 11, and the floating rust on the wind power tower is scraped off by the rust removal member 213 during the sliding process. The movable seat 211 can be reciprocated in the slide slot 11 for many times, and the position of the rust removal member 213 can be changed by adjusting the rotation adjustment bracket 322 and the pitch angle adjustment bracket 2122 during the rust removal process, so as to scrape off the floating rust on the outer wall of the wind power tower. The scraped floating rust is collected by the first collecting tank 23.

[0090] After the rust removal work in this area is completed, the climbing mechanism 33 drives the automatic paint spraying device to climb upward. During the climbing, the climbing wheel 332 is driven to rotate by the second rotating device 331 to achieve upward climbing, and then the area where the rust removal is completed can be painted, while the rust removal component 2 removes rust in the next area. The painting process is as follows: the anti-corrosion paint in the paint storage bin 41 is sent to the spray head 423 through the paint delivery pipe 43 by the paint pump 44, and the spray head 423 performs the painting work. During the painting, the spray head 423 can be driven to rise and fall by the connecting plate 4223 and can be driven to rotate by the rotating part 4225 to change the painting position and angle. The wind power tower is fully painted by the cooperation of multiple groups of spray heads 423. The anti-corrosion paint scattered during the painting process is collected by the second collection tank 45.

[0091] The second rotating device 331 in the climbing mechanism 33 drives the climbing wheel 332 to rotate and drives the automatic painting device to rise, gradually removing rust and painting each area of ​​the wind power tower, and gradually completing the painting work of the wind power tower from bottom to top. In addition, during the rising process, the sensing probe 34 will monitor in real time, control the variable diameter adjustment mechanism 32 according to the diameter change of the wind power tower, and drive the bracket 322 to rotate through the first rotating device 321 to match the diameter change of the wind power tower, so as to ensure the smooth climbing of the automatic painting device.

[0092] During the operation of the automatic painting device, if an unexpected situation occurs and the automatic painting device begins to fall, it will be sensed by the height detection device 51, and then the hydraulic drive component 521 will extend to drive the friction strip 523 on the brake plate 522 to contact and rub against the wind power tower, and friction braking will be performed until the automatic painting device stops falling.

[0093] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
