The present invention will be described in detail with reference to the accompanying drawings and examples.
As shown in fig. 1 and 2, the present invention provides a fan blade cleaning device for a wind driven generator, which includes a frame 10, an adsorption assembly 20, a lifter 30, a telescopic device 40 and a cleaning device 50. A plurality of universal wheels 11 for supporting the frame 10 to move on the surface of the tower of the wind driven generator are arranged on the front surface of the frame 10. The adsorption assembly 20 is disposed on the front surface of the frame 10, and is used for generating adsorption force to the tower. Two lifters 30 are installed on the frame 10. The first end of the telescopic device 40 is attached to the back of the frame 10. The cleaning device 50 is arranged at a second end of the telescopic device 40.
The working process of the invention is as follows: first, two steel ropes are suspended on top of the wind turbine tower and pass through the working ends of two hoists 30 in a one-to-one correspondence before starting the present invention. Meanwhile, the frame 10 is adsorbed on the surface of the tower through the adsorption assembly 20. Then, the elevator 30 is started, and the elevator 30 ascends along the steel rope when running, so that the frame 10 ascends along the surface of the tower until the frame 10 reaches the height of the fan blade. The extension of the telescopic device 40 is controlled, and the cleaning device is sent to the position where the fan blade is located, so that the fan blade is cleaned. Specifically, when cleaning a certain fan blade, the fan blade is adjusted to be arranged in the vertical direction, and the fan blade angle of the wind driven generator can be controlled, so that the fan blade angle can be adjusted to the normal line of the vertical section of the fan blade passing through the side wall of the tower barrel, and the fan blade can be cleaned thoroughly under the angle. Then, the lifting machine 30 is controlled to climb or descend, so that cleaning can be performed on different height positions of the fan blade; the extension length of the telescopic device 40 is controlled, so that cleaning can be performed at different transverse positions at the same height of the fan blade.
Further, as shown in fig. 3, the telescopic device 40 includes a horizontal connecting frame 41, a link telescopic mechanism 43 and an electric push rod 46, one end of the horizontal connecting frame 41 is fixedly connected with the frame 10, a horizontal guide rail 42 is provided on the horizontal connecting frame 41, a plurality of first sliding blocks 44 are provided on the link telescopic mechanism 43 at intervals, a fixed block 45 is provided on the first end of the link telescopic mechanism 43, the first sliding blocks 44 are slidably connected with the horizontal guide rail 42, and the fixed block 45 is fixedly connected with the horizontal guide rail 42. The cleaning device 50 is connected to a second end of the link telescopic 43. The two ends of the electric push rod 46 are connected with different connecting rods in the connecting rod telescopic mechanism 43. The extension and shortening of the link expansion mechanism 43 can be controlled by the extension and shortening of the electric push rod 46. When the link telescopic mechanism 43 is extended, the front portion of the link telescopic mechanism 43 protrudes out of the horizontal link 41.
Further, as shown in fig. 4 and 5, the cleaning apparatus 50 includes a rotary brush head 51, a brush head motor 52, a fixing frame 53, and a brush head position adjustment assembly 54. The fixed frame 53 is fixedly connected with the second end of the telescopic device 40, the output end of the brush head motor 52 is connected with the rotary brush head 51, and the brush head position adjusting assembly 54 is arranged between the brush head motor 52 and the fixed frame 53. The axial direction of the brush head motor 52 is perpendicular to the telescoping direction of the telescoping device 40. The brush head position adjusting assembly 54 includes a guide rail 541, a second slider 542, a motor mounting plate 543, and a linear motion output mechanism 544, the guide rail 541 is slidably connected to the fixing frame 53, the second slider 542 is slidably connected to the guide rail 541, the motor mounting plate 543 is fixedly supported on the second slider 542, and the brush head motor 52 is fixedly connected to the motor mounting plate 543. One end of the guide rail 541, which is close to the rotary brush head, is connected to the motor mounting plate 543 via a spring 545. The linear motion output mechanism 544 is fixedly connected to the fixed frame 53, and the linear motion output mechanism 544 is used for driving the guide rail 541 to move linearly or back on the fixed frame 53. The guide rails 541 are arranged in pairs, the guide rails 541 in pairs are fixedly connected through the beam 546, and the output end of the linear motion output mechanism 544 is fixedly connected with the beam 546. A travel switch 547 is fixedly supported by the cross member 546, the travel switch 547 being positioned behind the motor mounting plate 543, and the travel switch 547 being electrically connected to the linear motion output mechanism 544. When the motor mounting plate 543 touches the travel switch 547, the linear motion output mechanism 544 stops outputting linear motion. The brush head position adjustment assembly 54 is used to keep the rotating brush head 51 in constant contact with the surfaces of the blades during operation. Specifically, when cleaning is required to be performed on the blade surface, the guide rail 541 may be driven to advance by the linear motion output mechanism 544, during the advancing process of the guide rail 541, the spring 545 pulls the brush head motor 52 and the rotary brush head 51 to advance, when the rotary brush head 51 advances until the rotary brush head contacts the blade surface, the advancing is stopped, at this time, the motor mounting plate 543 is also stopped, and the guide rail 541 continues to advance under the driving of the linear motion output mechanism 544 until the travel switch 547 contacts the motor mounting plate 543, at this time, the motor mounting plate 543 touches the travel switch 547, and the linear motion output mechanism 544 electrically connected to the travel switch 547 stops outputting the linear motion. This means that the linear motion output mechanism 544 will cease to output linear motion whenever the rotating brush head 51 is in contact with the blade surface, and when the rotating brush head 51 is disengaged from the blade surface, the linear motion output mechanism 544 will again be activated, thereby ensuring that the rotating brush head 51 is always in contact with the blade surface during cleaning. When the cleaning work is completed, the guide rail 541 can be recovered backward through the linear motion output mechanism 544, so that the rotary brush head 51 is separated from the surfaces of the fan blades, and the whole cleaning device is controlled to descend at the moment, so that secondary pollution to the cleaned parts of the fan blades caused by the rotary brush head 51 in the descending process can be avoided.
Further, as shown in fig. 6 and 7, the suction assembly 20 includes a bracket 21, a magnet 22, a second rail 23, and a second linear motion output mechanism 24. The second guide rail 23 is slidably connected with the frame 10, the bracket 21 is slidably arranged on the second guide rail 23 through a third slide block 25, and the magnet 22 is fixedly arranged on the bracket 21. The second linear motion output mechanism 24 is fixedly connected to the frame 10. The output end of the second linear motion output mechanism 24 is directly or indirectly connected with the second guide rail 23, and is used for driving the second guide rail 23 to linearly travel or retreat on the frame 10. The front end of the second guide rail 23 is connected to the bracket 21 or the third slider 25 through a second spring 26. Two universal wheels 27 are provided on the front face of the support 21, one of the universal wheels 27 being located above the magnet 22 and the other universal wheel 27 being located below the magnet 22. Wherein, the magnet 22 can be a permanent magnet or an electromagnet. The second linear motion output mechanism 24 and the second guide rail 23 are provided such that the front-rear distance of the magnet 22 is adjustable, thereby adjusting the attraction force.
Further, as shown in fig. 8, the present invention further includes a wire rope distance positioning mechanism 60, and the wire rope distance positioning mechanism 60 includes an arc arm 61, a mount 62, and a permanent magnet jack 63. The mounting seats 62 are two and are arranged at both ends of the arc-shaped arm 61. The number of the permanent magnet jacks 63 is two, and each permanent magnet jack 63 is fixedly connected with one mounting seat 62. A pulley seat 64 is disposed at the end of each mounting seat 62, each pulley seat 64 rotatably supports a pulley 65, and a positioning through groove for positioning the steel rope in the horizontal direction is formed between the pulley 65 and the pulley seat 64 for passing the steel rope. The distance between the two positioning through grooves is equal to the distance between the two lifters 30. A row of rollers 66 are rotatably connected to the front face of each mounting block 62, and the permanent magnet jacks 63 are located on the rear side of the rollers 66. The mounting seat 62 is hinged with the arc arm 61, and a limiting component (not shown in the figure) for preventing the mounting seat 62 from rotating towards the arc back direction of the arc arm 61 is arranged at the end part of the arc arm 61. The mount 62 can only rotate in the direction of the inner side of the arc arm 61 by the stopper. The steel rope distance positioning mechanism 60 can protect the whole device, the steel rope distance positioning mechanism 60 is adsorbed on the side wall of the wind driven generator tower barrel, which is close to the top, by using the permanent magnet jacks 63 at two ends during operation, and two steel ropes hang down after passing through the positioning through grooves at two ends of the steel rope distance positioning mechanism 60, so that the distance between the two hung steel ropes is equal to the distance between the two lifters 30, and the smooth operation of the lifters 30 is ensured. Without the wire rope distance positioning mechanism 60, the distance between the two wires would normally be 2-4 times the distance between the two lifts 30, in which case the lifts 60 would be very vulnerable to damage when driving the frame up to the upper part of the tower.
Further, the rotating brush head 51 is connected with the rotating shaft of the brush head motor 52 through the universal shaft 56, so that the angle of the rotating brush head 51 can be changed, and the change of the curved surface shape of the fan blade surface can be well adapted.
Further, the cleaning apparatus further comprises a water tank, a water spray pipe and a water pump (not shown), wherein the water tank is provided on the frame 10 and connected with the water spray pipe through the water pump, and an outlet of the water spray pipe is located above the rotary brush head 51.

Further, a plurality of second travel switches 12 are provided at the top of the frame 10, the second travel switches 12 are electrically connected to the elevator 30, and the elevator 30 stops climbing when the second travel switches 12 are contacted. In the process of climbing along the tower of the wind driven generator by the cleaning device, when climbing is higher, an operator can not accurately judge the accurate position of the frame on the tower, and in order to prevent the main shaft of the wind driven generator from being impacted due to the climbing is too high, the second travel switch 12 is arranged, and once the second travel switch 12 is in contact with an external object, the lifting machine 30 stops climbing.
Further, the linear motion output mechanism 544 and the second linear motion output mechanism 24 are electric push rods or cylinders.
