Description

Technical Field

[0001] The present invention belongs to the technical field of wind power equipment cleaning, and specifically relates to a wind turbine blade cleaning device. Background Art

[0002] As an important way to obtain renewable energy, wind power generation has been widely applied and rapidly developed globally. As a key component for a wind turbine to capture wind energy, the performance of the blade directly affects the operating efficiency and power generation of the entire wind power generation equipment.

[0003] When the wind power generation equipment is used for a long time, dust will adhere to the blades. Although rainwater flushing can remove some dust, long-term action may cause damage to the surface coating of the blades and accelerate the aging of the blades. The excrement of insects and birds adheres to the surface of the blades, which not only affects the appearance but may also affect the balance of the blades due to the increase in local weight. In addition, ultraviolet rays in sunlight will age the blade material and reduce the mechanical strength of the blades.

[0004] There are various methods for cleaning the blades, such as manual climbing the tower barrel for cleaning, ground water spraying equipment for cleaning, and drone water spraying for cleaning, etc. When using the water spraying method to clean the blades, although the dust, dirt, and bird droppings on the blade surface can be removed;

[0005] However, when the water sprayed by the high-pressure water gun acts on the blade, the water flow will splash. When the water flow splashes, it will carry the removed dust, dirt, or bird droppings and splash, thus splashing onto the part of the blade that has been cleaned, resulting in secondary pollution of the blade. Summary of the Invention

[0019] Preferably, the first chute is inclined towards the traveling wheel side.

[0020] The cross bar in the first chute is also in an inclined state; a plurality of the first shielding plates in the first chute are also inclined towards the traveling wheel side.

[0021] On the side of the first shielding plate close to the traveling wheel, a second roller is rotatably connected, and the second roller is made of magnetic material.

[0022] On the side of a plurality of the first shielding plates facing the traveling wheel, inclined grooves are opened in the inner wall of the top plate; a diversion pipe is installed in the inclined grooves, and the diversion pipe extends into the waste water tank outside.

[0023] Preferably, notches are opened on both sides of each second shielding plate.

In the wind turbine blade cleaning device of the present invention, by providing a plurality of baffle plates that can be individually extended, the baffle plates can move along the arc surface of the blade, so as to adapt to the arc surfaces at different positions of the blade, and thus better block the splashing water flow, avoiding excessive water flow splashing out from the cleaning assembly; at the same time, since the side plates slide within the top plate, when the heights of the blades at both sides of the top plate are inconsistent, the side plates will slide out of the top plate at this time and be adsorbed on the blade by the magnetic first rollers, which can also block the splashing water flow and reduce the amount of water splashing out from the cleaning assembly.

[0039] 3. In the wind turbine blade cleaning device of the present invention, since cleaning brushes are fixedly connected to the rotating rods, when the traveling wheels rotate along the blade, the rotating traveling wheels will drive the cleaning brushes to rotate, and the rotating cleaning brushes will brush the surface of the blade, so as to brush off the stubborn stains on the blade surface. At the same time, since the nozzles are located between adjacent cleaning brushes, the cleaning brushes can block the splashing water, thereby further reducing the range of water flow splashing.

Cleaning brush Detailed implementation manners

[0052] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners

[0053] Embodiment 1:

[0054] As Figures 1 to 10 shown, a wind turbine blade cleaning device according to the present invention; includes a cleaning assembly; the cleaning assembly includes a top plate 1; a liquid cavity 11 is provided inside the top plate 1; a water inlet pipe 12 is connected to the top of the top plate 1, and one side of the water inlet pipe 12 is communicated with the liquid cavity 11, and the other side is connected to an external water tank

[0055] Two rows of sprayers 13 are installed at the bottom of the top plate 1, and the number of each row of sprayers 13 is multiple; each sprayer 13 is communicated with the liquid cavity 11

[0056] Tractor frames 14 are installed on both ends of the top surface of the top plate 1 on both sides of the water inlet pipe 12; traction ropes 15 are fixedly connected to both tractor frames 14; the other end of the traction rope 15 is installed on a drone through a tractor rod 16

[0057] Three rows of traveling wheels 17 are fixedly installed on the bottom end surface of the top plate 1; the middle traveling wheel 17 is located between the two rows of sprayers 13; each traveling wheel 17 is made of a magnetic material and is used to adsorb and walk on the blade

[0058] Side plates 18 are provided on both sides of the traveling wheel 17 on the bottom surface of the top plate 1, and the side plates 18 are slidably arranged inside the top plate 1; uniformly arranged first rollers 19 are installed at the bottom of the baffle plates, and the first rollers 19 are made of a magnetic material

[0059] Blocking assemblies are provided at both positions of the top plate 1 where the side plates 18 are not provided, and the blocking assemblies are used to block the water mist splashed when the sprayers 13 spray on the fan blades

[0060] In this embodiment, the shielding component includes a chute;

[0061] On the opposite sides of the two side plates 18, two chutes are provided in the top plate 1, namely a first chute 2 and a second chute 21; three rows of the walking wheels 17 are located between the two chutes;

[0062] A shielding plate is slidably connected in each of the two chutes, and the adjacent shielding plates are in contact with each other; the shielding plate in the first chute 2 is a first shielding plate 22, and the shielding plate in the second chute 21 is a second shielding plate 23;

[0063] A plurality of the shielding plates are completely slid in the chutes; the shielding plates close to the side plates 18 are in contact with the adjacent side plates 18;

[0064] A return groove 24 is provided in the middle of each shielding plate; a cross bar 25 is fixedly connected in each of the two chutes; the cross bars 25 in the two chutes respectively pass through the return grooves 24 of the shielding plates;

[0065] On the surface of one side of the two cross bars 25 facing the walking wheels 17, springs are uniformly arranged, and the other sides of the springs are respectively fixedly connected in the return grooves 24 of the shielding plates;

[0066] Specifically, when cleaning the blade, the staff rises to the top of the nacelle through the elevator inside the tower barrel, and then controls the blade to be cleaned to rotate to the vertically downward state. Then, the towing rope 15 on the cleaning component is first connected to the towing rod 16 on the unmanned aerial vehicle, and then the cleaning component is attached to the vertically downward blade. When the cleaning component is attached above the blade, the walking wheels 17 on the cleaning component will adsorb on the blade, and at the same time, a plurality of first rollers 19 on the two side plates 18 on both sides of the top plate 1 also adsorb on the blade. Then, the unmanned aerial vehicle is controlled to take off and tow the cleaning component. The towed cleaning component will move from top to bottom on the blade. At the same time, water in the water tank is introduced into the liquid cavity 11 through the water inlet pipe 12, and the water entering the liquid cavity 11 will be sprayed out through the uniformly arranged nozzles 13, so that the surface of the blade can be cleaned;

[0067] More specifically, since a plurality of mutually fitting baffle plates are slidably connected in the two sliding grooves on both sides of the top plate 1, when the traveling wheels 17 are adsorbed on the surface of the blade, at this time, the baffle plates in the two sliding grooves will abut against the surface of the blade under the action of the springs on the cross bar 25. Therefore, the first baffle plate 22 and the second baffle plate 23 can block the two sides where the side plates 18 are not installed. Since the baffle plates close to the side plates 18 are all in contact with the adjacent side plates 18, the spray head 13 and the sprayed water flow can be restricted within the space formed by the two side plates 18, the first baffle plate 22 and the second baffle plate 23. Subsequently, during the process of the cleaning assembly gradually moving downward on the blade from top to bottom, the water sprayed by the spray head 13 can clean the blade located below the cleaning assembly from top to bottom. At the same time, due to the presence of the side plates 18, the first baffle plate 22 and the second baffle plate 23, most of the water splashed on the blade by the spray head 13 will be blocked by the side plates 18, the first baffle plate 22 and the second baffle plate 23, thereby preventing too much water flow from splashing out of the cleaning assembly and carrying the dust, dirt or bird droppings washed away, which may splash onto the part of the blade where the cleaning is completed, resulting in secondary pollution of the blade;

[0068] Furthermore, since a plurality of the first baffle plates 22 and the second baffle plates 23 exist independently, when the downward moving cleaning assembly moves to the arc surface position of the blade, at this time, the independent first baffle plate 22 or the second baffle plate 23 is blocked by the arc surface and will slide in the first sliding groove 2 or the second sliding groove 21. At the same time, the loop groove 24 will also slide along the cross bar 25, thereby preventing the first baffle plate 22 or the second baffle plate 23 from still fitting the blade when passing through the arc surface; during this process, by setting a plurality of baffle plates that can be independently extended, the baffle plates can move along the arc surface on the blade, so as to adapt to the arc surfaces at different positions of the blade, thereby better blocking the splashed water flow and preventing too much water flow from splashing out of the cleaning assembly; at the same time, since the side plates 18 slide in the top plate 1, when the heights of the blades at both sides of the top plate 1 are inconsistent, at this time, the side plates 18 will slide out of the top plate 1 and be adsorbed on the blade by the magnetic first rollers 19, which can also block the splashed water flow and reduce the amount of water splashed out of the cleaning assembly;

[0069] Even further, when the drone carries the cleaning assembly and moves down to the end position of the blade, the drone is used to tow the cleaning assembly to move to the top position of the blade again, and then the position of the cleaning assembly is adjusted to clean the unwashed position of the blade, and this is repeated to clean the blade.

[0070] Embodiment 2:

[0071] The first sliding groove 2 is inclined towards the side of the traveling wheel 17;

[0072] The cross bar 25 in the first chute 2 is also in an inclined state; multiple first baffle plates 22 in the first chute 2 also incline towards the side of the traveling wheel 17;

[0073] A second roller 26 is rotatably connected to the side of the first baffle plate 22 close to the traveling wheel 17, and the second roller 26 is made of magnetic material;

[0074] On the side of multiple first baffle plates 22 facing the traveling wheel 17, an inclined groove 3 is formed in the inner wall of the top plate 1; a diversion pipe 31 is installed in the inclined groove 3, and the diversion pipe 31 extends into the waste water tank outside;

[0075] In this embodiment, notches 4 are formed on both sides of each second baffle plate 23;

[0076] A roller 41 is rotatably connected to each notch 4; a conveyor belt 42 is rotatably connected to the two rollers 41 on each second baffle plate 23; the conveyor belt 42 passes through the second chute 21; the conveyor belt 42 is made of absorbent cotton material;

[0077] Specifically, since the second roller 26 with magnetism is rotatably connected to the bottom of the first baffle plate 22, the second roller 26 will adsorb on the blade and rotate along the blade, so that the first baffle plate 22 can be adsorbed on the blade to prevent the first baffle plate 22 from detaching from the blade;

[0078] More specifically, since the first baffle plate 22 inclines towards the side of the traveling wheel 17, when the cleaning assembly moves downwards along the vertical blade from top to bottom, the water for cleaning the blade will flow along the blade. When the water flows to the position of the first baffle plate 22, most of the water flow will flow along the first baffle plate 22. When the water flows to the position of the inclined groove 3, the water flow will flow into the waste water tank through the diversion pipe 31. In this process, most of the sewage after cleaning the blade can be discharged, so as to prevent too much sewage from flowing along the blade and carrying too many impurities to adhere to the uncleaned position of the blade again;

[0079] Furthermore, since the roller 41 is rotatably connected to the notch 4 of the second baffle plate 23, and the conveyor belt 42 is rotatably connected to the two rollers 41, when the second baffle plate 23 moves along the blade, the conveyor belt 42 will be driven to rotate by the roller 41. The rotating conveyor belt 42 can wipe the part cleaned by the nozzle 13 and absorb the remaining water on the blade at the same time. When the remaining water on the blade is absorbed, if there is dust in the external environment, since the conveyor belt 42 absorbs the water on the blade, the difficulty of dust adhering to the cleaned blade can be increased, so as to prevent some dust from adhering to the water stain on the blade when the blade is just cleaned.

[0080] Embodiment Three:

[0081] The top surface of the top plate 1 is rotatably connected with a pressing roller 43, and the pressing roller 43 contacts the conveyor belt 42 and presses the conveyor belt 42;

[0082] The conveyor belt 42 is driven by a motor 44;

[0083] In this embodiment, uniformly arranged teeth 45 are fixedly connected to the surface of the roller 41 in each second baffle 23;

[0084] Uniformly arranged tooth grooves 46 are formed on the inner circumferential surface of each conveyor belt 42, and the teeth 45 are engaged with the tooth grooves 46; the teeth 45 are made of magnetic material;

[0085] In this embodiment, an arc-shaped bin 32 is fixedly connected to the surface of the top plate 1 on the side of the first chute 2 facing the second chute 21;

[0086] The bottom of the arc-shaped bin 32 is fixedly connected with a conduit 33, and the other side of the conduit 33 is communicated with a diversion pipe 31;

[0087] On the side of the second chute 21 facing the first chute 2, a diversion groove 34 is formed on the top surface of the top plate 1, and the diversion groove 34 extends into the arc-shaped bin 32;

[0088] Specifically, since the pressing roller 43 is driven by the motor 44, when the cleaning component cleans the blade, the motor 44 is controlled to drive the pressing roller 43 to rotate. The rotating pressing roller 43 will press the conveyor belt 42 while pushing the conveyor belt 42 to rotate. When the conveyor belt 42 is pressed, the adsorbed water in the conveyor belt 42 will be squeezed out. The squeezed water will drip downward and drip into the arc-shaped bin 32, and then be discharged into the diversion pipe 31 through the conduit 33. If part of the water adheres to the top plate 1, this part of the water will flow downward along the diversion groove 34 and gradually flow into the arc-shaped bin 32;

[0089] More specifically, since the teeth 45 fixedly connected to the roller 41 are engaged with the tooth grooves 46 on the conveyor belt 42, and the teeth 45 are made of magnetic material, the teeth 45 will adsorb on the surface of the blade, thereby increasing the contact force between the second baffle 23 and the blade and preventing the second baffle 23 from detaching from the blade. When the pressing roller 43 drives the conveyor belt 42 to rotate, the conveyor belt 42 will drive the roller 41 to rotate, and the rotating roller 41 will drive the conveyor belt 42 to rotate.

[0090] Embodiment 4:

[0091] The number of each row of the walking wheels 17 is two;

[0092] The positions of the walking wheels 17 in the middle row are staggered with the positions of the walking wheels 17 in the upper and lower rows;

[0093] In this embodiment, a rotating rod 5 is fixedly connected to the two walking wheels 17 in each row together;

[0094] A cleaning brush 51 is fixedly connected to the rotating rod 5 between the two walking wheels 17 in the upper and lower rows; a cleaning brush 51 is fixedly connected to the rotating rod 5 between the two walking wheels 17 in the middle row and on both sides;

[0095] Specifically, since the cleaning brush 51 is fixedly connected to the rotating rod 5, when the walking wheel 17 rotates along the blade, the rotating walking wheel 17 will drive the cleaning brush 51 to rotate, and the rotating cleaning brush 51 will brush the surface of the blade, so that the stubborn stains on the surface of the blade can be brushed off. At the same time, since the nozzle 13 is located between the adjacent cleaning brushes 51, the cleaning brush 51 can block the splashing water, thereby further reducing the range of water flow splashing;

[0096] More specifically, since the cleaning brush 51 is provided on the three rows of walking wheels 17, the area where the nozzle 13 sprays water can be brushed, so as to avoid some areas not being brushed, resulting in the inability to remove the stubborn stains at the unbrushed positions.

[0097] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
