[0001] The present application relates to the technical field of wind power equipment maintenance, and in particular to a wind power equipment cleaning device. BACKGROUND

[0002] Under the background of rapid development of new energy industry, as an important part of green energy, the installed capacity of wind power continues to rise. However, the wind turbine blades are exposed to the complex outdoor environment for a long time, and are easily attached by pollutants such as dust, bird droppings, and insect carcasses, which increases the roughness of the blade surface and changes the aerodynamic shape. The blade surface pollution can reduce the power generation efficiency of the wind turbine by 10%-30%, significantly shorten the service life of the equipment, and greatly increase the operation and maintenance cost.

[0003] The installation height of the fan blade is usually 80-120 meters.

[0040] In order to enable those skilled in the art to better understand the present invention, the present invention is further described in detail below with reference to specific embodiments and the accompanying drawings.

[0041] The terms used in the present invention are those commonly used in the art in view of the functions of the present invention, but these terms may vary according to the intentions of those skilled in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as the meanings of the terms and the overall description of the present invention.

[0042] Reference Figures 1 to 7 This embodiment provides a wind power equipment cleaning device, including an adsorption mobile vehicle 1. In this embodiment, the adsorption mobile vehicle 1 can be a negative pressure adsorption climbing vehicle or a magnetic climbing vehicle, which is adsorbed on the surface of the wind power equipment by negative pressure adsorption or magnetic force and performs mobile operations.

[0043] The adsorption mobile vehicle 1 is provided with a driving motor 2, the output end of the driving motor 2 is provided with a rotating shaft 3, and the rotating shaft 3 is provided with a blade wheel 31; the operation of the driving motor 2 can cause the rotating shaft 3 to rotate, and the rotating shaft 3 and the blade wheel 31 are fixedly connected.

[0044] The adsorption mobile vehicle 1 is provided with a fixed frame 4, a deflector 5 is provided on the outer rotation of the rotating shaft 3, a pusher 7 is provided on the fixed frame 4, and a ring cover 8 is provided on the pusher 7;

[0045] The fixing frame 4 is fixed on the adsorption mobile vehicle 1, the deflector 5 can rotate on the outer wall of the rotating shaft 3, and the pushing member 7 can generate a downward thrust, so that the annular cover 8 maintains a tendency to move in one direction.

[0046] A locking ring 54 is provided on the air deflector 5, a tooth groove 541 is provided on the locking ring 54, and a clamping block 81 is provided on the ring cover 8; after the clamping block 81 is clamped in the tooth groove 541 on the locking ring 54, the position of the air deflector 5 can be fixed to lock the air deflector 5 and prevent the air deflector 5 from rotating.

[0047] A plurality of cleaning brushes 53 arranged in a circumference are rotatably provided on the deflector 5 ; the cleaning brushes 53 are used to clean the surface of the wind power equipment.

[0048] A limiting member 33 is provided on the rotating shaft 3 ; the limiting member 33 is used to control the position of the ring cover 8 .

[0049] When the rotating shaft 3 rotates in the first direction, the engaging block 81 engages with the tooth groove 541; for example, referring to Figure 5 When the first direction is counterclockwise rotation, after the engaging block 81 and the tooth groove 541 are engaged, the air deflector 5 is in a fixed state and does not rotate with the rotation of the rotating shaft 3.

[0050] When the rotating shaft 3 rotates in the second direction, the limiting member 33 and the locking ring 54 are engaged with each other. Figure 5 When the second direction is clockwise rotation, the limiter 33 pushes the ring cover 8 to make it coaxial with the locking ring 54, causing the clamping block 81 to disengage from the tooth groove 541, and the limiter 33 is stuck on the locking ring 54. At this time, when the rotating shaft 3 rotates, it will drive the air deflector 5 to rotate together, thereby causing the cleaning brush 53 on the air deflector 5 to rotate.

[0051] When in use, the adsorption mobile vehicle 1 moves, and the surface of the wind turbine equipment is cleaned by the cleaning brush 53 during the movement. The driving motor 2 controls the rotating shaft 3 to rotate. When the rotating shaft 3 rotates, the blade wheel 31 rotates, and the gas can pass through each cleaning brush 53. The flow of gas can assist in cleaning the surface of the wind turbine equipment. In addition, since the gas passes through the cleaning brush 53, the gas can also clean the cleaning brush 53 to keep the cleaning brush 53 clean and tidy. By controlling the rotation direction of the rotating shaft 3, it is possible to control whether the deflector 5 is rotated. For example, referring to Figure 5 When the rotating shaft 3 rotates clockwise, the limiter 33 pushes the ring cover 8 to make it coaxial with the locking ring 54, causing the clamping block 81 to disengage from the tooth groove 541, and the limiter 33 is stuck on the locking ring 54. At this time, when the rotating shaft 3 rotates, it will drive the air deflector 5 to rotate together, thereby causing the cleaning brush 53 on the air deflector 5 to rotate, so as to facilitate the continuous use of different cleaning brushes 53 for cleaning operations. Since the cleaning time of a single cleaning brush 53 is short, the dust stuck to it will not be too much. At this time, the wind force generated by the rotation of the impeller 31 can easily blow off the dust to maintain the cleaning operation of the cleaning brush 53. By controlling the rotation angle of the rotating shaft 3, the cleaning brush 53 can be switched.

[0052] In addition, when the rotating shaft 3 rotates counterclockwise, after the engaging block 81 and the tooth groove 541 are engaged, the air deflector 5 is in a fixed state. At this time, a single cleaning brush 53 can perform cleaning work for a longer time. The advantage of this working method is that cleaning brushes 53 of different hardness can be set, and cleaning brushes 53 of different hardness are used for cleaning in different stages. Each part is cleaned in each stage, which can also ensure that while cleaning effectively, each cleaning brush 53 has sufficient time to blow away the adhered dust and dirt. Specifically, in the first step, use the hardest cleaning brush 53 to clean one to two times, and then switch to the second hardest cleaning brush 53 to clean one to two times, and so on, to achieve gradual cleaning.

[0053] As an optional embodiment: an exchange channel 51 is provided on the air deflector 5, a rotating seat 52 is provided on the outer wall of the air deflector 5, and a cleaning brush 53 is rotatably provided on the rotating seat 52; the exchange channel 51 serves as a channel for air flow in and out, and the rotating seat 52 is used to install the cleaning brush 53, and the cleaning brush 53 can rotate on the rotating seat 52.

[0054] The impeller 31 is disposed in the air deflector 5 . The rotation of the impeller 31 can cause the airflow in the air deflector 5 to flow. By controlling the rotation direction of the impeller 31 , the flow direction of the airflow can be controlled.

[0055] As an optional embodiment: the cleaning brush 53 includes a rotating sleeve 531 rotatably arranged on the rotating seat 52, and a bracket 532 arranged on the rotating sleeve 531, and bristles 533 are arranged on the bracket 532. Figure 2 and Figure 3 The bracket 532 is provided with three circumferentially distributed fan-shaped cavities to facilitate the circulation of gas, and the rotating sleeve 531 can rotate on the rotating seat 52.

[0056] As an optional embodiment: a first bevel gear 34 is provided on the rotating shaft 3; the first bevel gear 34 is fixedly connected to the rotating shaft 3.

[0057] It also includes a transmission member 6 rotatably mounted on the fixing frame 4;

[0058] The transmission member 6 includes a connecting shaft 61 rotatably mounted on the fixing frame 4, a second bevel gear 62 mounted at the end of the connecting shaft 61, and a rubber disc 63 mounted at the end of the connecting shaft 61.

[0059] A rubber sleeve 534 is provided on the outer wall of the rotating sleeve 531 .

[0060] It should be noted that the rotating shaft 3 is arranged through the fixed frame 4, the connecting shaft 61 is arranged through the fixed frame 4, the rotating shaft 3 and the fixed frame 4 are rotationally connected, the connecting shaft 61 and the fixed frame 4 are rotationally connected, the rotating shaft 3 and the connecting shaft 61 are perpendicular to each other, the first bevel gear 34 and the second bevel gear 62 are engaged with each other, the outer wall of the rubber disc 63 can conflict with the outer wall of the rubber sleeve 534, the outer wall of the rubber disc 63 and the outer wall of the rubber sleeve 534 are provided with anti-slip grooves, and the rotation of the rubber disc 63 can make the rubber sleeve 534 drive the rotating sleeve 531 to rotate.

[0061] As an optional embodiment: a receiving cavity 41 is provided on the fixing frame 4 ; the pushing member 7 includes a limiting column 71 slidably provided in the receiving cavity 41 , and a spring 72 provided in the receiving cavity 41 .

[0062] The limiting post 71 has a square structure or a triangular structure. The limiting post 71 can only slide in the accommodating cavity 41 and cannot rotate relative to it. The spring 72 can generate a thrust so that the limiting post 71 has a movement tendency to slide out of the accommodating cavity 41.

[0063] As an optional embodiment: the number of the tooth grooves 541 and the number of the cleaning brushes 53 are the same, and the tooth grooves 541 and the cleaning brushes 53 are arranged in a one-to-one correspondence.

[0064] The number of the tooth grooves 541 corresponds to the rotation angle of the air deflector 5 . When the number of the tooth grooves 541 and the number of the cleaning brushes 53 are the same, each cleaning brush 53 can be switched.

[0065] As an optional embodiment, the diameter of the locking ring 54 is larger than the diameter of the ring cover 8 .

[0066] Since the diameter of the locking ring 54 is larger than the diameter of the ring cover 8, the inner wall of the locking ring 54 will be in contact with the inner wall of the ring cover 8 under the push of the pusher 7. Figure 5 In the state shown, the engaging block 81 is engaged in the tooth groove 541 . When the locking ring 54 and the ring cover 8 are concentrically arranged, the ring cover 8 is disengaged from the tooth groove 541 .

[0067] As an optional embodiment: a flywheel 32 is provided on the rotating shaft 3 , and an inclined groove 321 is provided on the flywheel 32 ; the flywheel 32 is rotatably provided on the outer wall of the rotating shaft 3 .

[0068] The limiting member 33 includes a fixed rod 331 fixed on the rotating shaft 3 and a deflection rod 332 rotatably mounted on the fixed rod 331 . The deflection rod 332 is provided with a sliding column 333 , an abutment end 334 , and a guide wheel 335 .

[0069] The sliding post 333 is slidably disposed inside the inclined groove 321 .

[0070] Reference Figure 5 , Figure 5 When the cam 331 is in the closed position, the cam 332 is in the closed position, and the cam 333 is in the closed position, so that the cam 333 is in the closed position, and the cam 333 is in the closed position, so that the cam 333 is in the closed position, and the cam 333 is in the closed position, so that the cam 333 is in the closed position, and the cam 333 is in the closed position, so that the cam 333 is in the closed position, and the cam 333 is in the closed position, so that the cam 333 is in the closed position, and the cam 333 is in the closed position, so that the cam 333 is in the closed position,

[0071] In addition, due to the rotation of the rotating shaft 3, the second bevel gear 62 is driven to rotate through the first bevel gear 34, so that the rubber disc 63 rotates rapidly. The rubber disc 63 continuously fits with the rubber sleeve 534 on the cleaning brush 53 at different positions, which can make the cleaning brush 53 at various positions rotate to a certain extent. The rotation and displacement of the cleaning brush 53 itself can further improve the cleaning effect.

[0072] When the rotating shaft 3 rotates counterclockwise, due to the inertia of the flywheel 32 and the inertia of the deflection rod 332, the rotating shaft 3 will pull the deflection rod 332 through the fixed rod 331 when it rotates, so that the sliding column 333 is located in the inclined groove 321 close to the end of the rotating shaft 3, so that the guide wheel 335 will not expand to push the ring cover 8 to rise, thereby ensuring the clamping connection between the clamping block 81 and the tooth groove 541, and the abutting end 334 does not abut on the inner wall of the locking ring 54, so when the rotating shaft 3 rotates, the air deflector 5 will not rotate, the cleaning brush 53 will not be switched, and the rotation of the rubber disc 63 will cause the cleaning brush 53 at the corresponding position to rotate for continuous cleaning.

[0073] As an optional embodiment, the length of the fixed rod 331 plus the length from the connection between the fixed rod 331 and the deflection rod 332 to the location of the sliding post 333 is greater than the maximum length of the inclined slot 321 from the outer wall of the rotating shaft 3 .

[0074] Reference Figure 5 Since the length of the fixed rod 331 plus the length from the connection between the fixed rod 331 and the deflection rod 332 to the position of the sliding post 333 is greater than the maximum length of the inclined groove 321 from the outer wall of the rotating shaft 3, when the rotating shaft 3 rotates clockwise, when the sliding post 333 moves to the end of the inclined groove 321 away from the rotating shaft 3, the fixed rod 331 and the deflection rod 332 can no longer deflect, and in the clockwise rotation direction, the contact end 334 is always in an outwardly extended state.

[0075] As an optional embodiment, the number of the limiting members 33 is the same as the number of the tooth grooves 541 , and the number of the inclined grooves 321 is the same as the number of the tooth grooves 541 .

[0076] When the number of the limiting members 33 is the same as the number of the tooth grooves 541, refer to Figure 5 When the rotating shaft 3 rotates clockwise, the fixed rod 331 pushes the deflection rod 332 to move, and the contact end 334 can form a snap-fit ​​relationship with the locking ring 54 by inserting into the tooth groove 541, thereby avoiding slipping and improving the stability of the transmission between the air deflector 5 and the contact end 334.

[0077] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
