Description

Technical Field

[0001] This invention relates to the field of wind power generation equipment technology, specifically to a water-flow cleaning device for wind turbine blades. Background Technology

[0002] A wind turbine blade is a long, wing-shaped structure with a specific aerodynamic shape that is mounted on the hub of a wind turbine. Its main function is to capture and effectively convert flowing wind energy into rotational mechanical energy.

[0003] Chinese patent application CN201710238253.6 discloses a water-flow cleaning device for wind turbine blades. Although this application achieves the goal of preventing dust accumulation on wind turbine blades through water circulation cleaning, when put into use, the curved shape of the wind turbine blades makes it difficult to effectively predict the water flow direction during cleaning. This results in the water sprayed being unable to effectively clean the blade edges, and it is also impossible to clean without shutting down the machine, making it quite inconvenient to use. Improvements are needed to address this problem. Summary of the Invention

[0004] The purpose of this invention is to provide a water-flow cleaning device for wind turbine blades to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a water flow cleaning device for wind turbine blades, including wind turbine blades and a support assembly, wherein working grooves are provided on both the front and back sides of the right side of the wind turbine blades.

[0006] The supporting components include: A fixed support plate is fixedly connected to the front of the working groove. A support spring is fixedly connected to the right side of the fixed support plate. A movable slide rod is slidably connected to the middle of the fixed support plate. A movable magnetic plate is fixedly connected to the end of the movable slide rod away from the support spring. A support plate is fixedly connected to the left side of the working groove. An electromagnetic plate is fixedly connected to the left side of the movable magnetic plate. The movable slide rod can slide in the middle of the fixed support plate.

[0007] According to the above technical solution, it also includes a cleaning assembly, which consists of a movable guide frame, a lifting limit rod, a compression spring, a movable cleaning frame, a fixed rod, and a cleaning roller.

[0008] The movable guide frame is fixedly connected to the end of the support spring away from the fixed support plate. The lifting limit rod is slidably connected to the inner top. The compression spring is fixedly connected to the bottom of the movable guide frame. The movable sweeping frame is fixedly connected to the bottom end of the compression spring. The fixed rod is fixedly connected to the inner bottom of the movable sweeping frame. The sweeping roller is rotatably connected to the middle of the fixed rod. The compression spring can support the movable sweeping frame.

[0009] According to the above technical solution, it also includes a water flow cleaning component, which consists of a water storage bladder, a squeezing cross plate, a telescopic water outlet pipe, a connecting pipe, a water storage bladder, and a water inlet pipe.

[0010] The first water storage bladder is fixedly connected to the left side of the fixed support horizontal plate, the compression horizontal plate is fixedly connected to the left side of the first water storage bladder, the telescopic water outlet pipe is fixedly connected to the right side of the first water storage bladder, the connecting pipe is fixedly connected to the top of the first water storage bladder, the second water storage bladder is fixedly connected to the end of the connecting pipe away from the connecting pipe, and the water inlet pipe is fixedly connected to the bottom of the first water storage bladder. The interior of the first water storage bladder is connected to the interior of the second water storage bladder through the connecting pipe.

[0011] According to the above technical solution, guide grooves are provided on the left and right sides of the fixed support plate to accommodate the sliding of the movable slide rod. The movable slide rod is slidably connected to the fixed support plate through the guide grooves. The right ends of the movable slide rod and the support spring are fixedly connected to the left side of the movable guide frame. The movable slide rod can move synchronously with the movement of the movable guide frame.

[0012] According to the above technical solution, the top and bottom of the movable guide frame are provided with through lifting grooves, the lifting limit rod is slidably connected to the movable guide frame through the lifting grooves, and the top of the lifting limit rod is provided with a limit circular plate, which can limit the lifting distance of the lifting limit rod.

[0013] According to the above technical solution, the telescopic water outlet pipe is located away from the water storage bladder and passes through the movable guide frame at one end, extending to the outside of the movable guide frame. The water inlet pipe is connected to the water outlet inside the generator. A pressure valve is installed inside the telescopic water outlet pipe. A protective groove is opened in the middle of the extrusion plate to accommodate the movement of the movable slide rod. The extrusion plate is slidably connected to the movable slide rod through the protective groove. When the extrusion plate is subjected to force, it will not push the movable slide rod to move synchronously.

[0014] According to the above technical solution, the fixed support horizontal plate, movable slide bar, support spring, movable magnetic plate, support fixing plate, electromagnetic plate, movable guide frame, lifting limit rod, compression spring, movable cleaning frame, fixed rod, cleaning roller, water storage bladder one, compression horizontal plate, telescopic water outlet pipe, connecting pipe, water storage bladder two, and water inlet pipe are all in pairs. The two fixed support horizontal plates, movable slide bars, support springs, movable magnetic plates, support fixing plates, electromagnetic plates, movable guide frames, lifting limit rods, compression springs, movable cleaning frames, fixed rods, cleaning rollers, water storage bladder one, compression horizontal plate, telescopic water outlet pipe, connecting pipe, water storage bladder two, and water inlet pipe are symmetrically distributed on the right front and back of the wind turbine blade. By setting them on the front and back of the wind turbine blade, the front and back edges of the wind turbine blade can be cleaned simultaneously.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. By setting components such as water storage bladders and water storage bladder II on the outer surface of the blade, the weight of this area is increased. When the blade rotates, the extra weight generates a greater centrifugal force, thereby accelerating the blade rotation speed. 2. Water is introduced into the first water storage bladder through the inlet pipe, and then flows into the second water storage bladder through the connecting pipe. After both bladders are full of water, the electromagnetic plate is disconnected. The moving magnetic plate pushes the squeezing plate under the action of the support spring, which compresses the first water storage bladder, causing the water to spray out through the telescopic outlet pipe. The water flow covers the front and back of the blade and swings in the direction of rotation when the blade rotates, washing the entire surface of the blade. The water flow finally swings out from the outer edge of the blade, achieving directional cleaning of the edge. The cleaning range is more comprehensive, preventing the aerodynamic performance degradation caused by dirt accumulation and improving the durability and operational stability of the blade. 3. During the blade rotation, after the electromagnetic plate is disconnected, the moving guide frame moves outward under the push of the spring, causing the cleaning roller to roll and contact the blade surface. The cleaning roller removes surface dust and loose dirt, preventing dirt from adhering or forming hard stains during subsequent water cleaning. It automatically removes surface dust before cleaning, reduces water flow resistance, improves cleaning efficiency, and ensures that the blade is cleaner after cleaning. 4. The compression spring and moving guide frame allow the cleaning roller and cleaning assembly to automatically adjust their position according to the blade curvature, which can adapt to different blade curvatures, keep the cleaning roller and water spray assembly in close contact with the blade surface, avoid cleaning dead corners, and improve overall reliability and cleaning uniformity. 5. The entire cleaning and sweeping process can be carried out while the wind turbine is running normally, which significantly reduces downtime and maintenance costs, avoids energy loss caused by power generation interruption, and improves the operating economy and sustainability of the wind turbine.

[0027] Water storage bladder 501 is fixedly connected to the left side of the fixed support plate 301. The compression plate 502 is fixedly connected to the left side of water storage bladder 501. The telescopic water outlet pipe 503 is fixedly connected to the right side of water storage bladder 501. The connecting pipe 504 is fixedly connected to the top of water storage bladder 501. Water storage bladder 505 is fixedly connected to the end of the connecting pipe 504 away from the connecting pipe 504. The water inlet pipe 506 is fixedly connected to the bottom of water storage bladder 501. The interior of water storage bladder 501 is connected to the interior of water storage bladder 505 through the connecting pipe 504.

[0028] The telescopic water outlet pipe 503 passes through the movable guide frame 401 at one end away from the water storage bladder 501 and extends to the outside of the movable guide frame 401. The water inlet pipe 506 is connected to the water outlet inside the generator. A pressure valve is installed inside the telescopic water outlet pipe 503. A protective groove is opened in the middle of the extrusion plate 502 to accommodate the movement of the movable slide rod 303. The extrusion plate 502 is slidably connected to the movable slide rod 303 through the protective groove. When the extrusion plate 502 is subjected to force, it will not push the movable slide rod 303 to move synchronously.

[0029] The following components are included: fixed support horizontal plate 301, movable slide bar 303, support spring 304, movable magnetic plate 305, support fixing plate 306, electromagnetic plate 307, movable guide frame 401, lifting limit rod 402, compression spring 403, movable sweeping frame 404, fixed rod 405, sweeping roller 406, water storage bladder one 501, compression horizontal plate 502, telescopic water outlet pipe 503, connecting pipe 504, water storage bladder two 505, and water inlet pipe 506, each in two quantities. Two fixed support horizontal plates 301, movable slide bar 303, support spring 304, and movable magnetic plate 305 are also included. Plate 305, support fixing plate 306, electromagnetic plate 307, movable guide frame 401, lifting limit rod 402, compression spring 403, movable sweeping frame 404, fixing rod 405, sweeping roller 406, water storage bladder 1 501, compression cross plate 502, telescopic water outlet pipe 503, connecting pipe 504, water storage bladder 2 505 and water inlet pipe 506 are symmetrically distributed on the front and back of the right side of the wind turbine blade 1. By setting them on the front and back of the wind turbine blade 1, the front and back edges of the wind turbine blade 1 can be cleaned at the same time.

[0030] When it is necessary to clean the edge of the wind turbine blade 1 without shutting down the machine, water from inside the wind turbine is introduced into the first water storage bladder 501 through the water inlet pipe 506, and the water in the first water storage bladder 501 flows into the second water storage bladder 505 through the connecting pipe 504, so that both the second water storage bladder 505 and the first water storage bladder 501 are filled with water. Then, the electromagnetic plate 307 is disconnected, causing the magnetic force between the electromagnetic plate 307 and the moving magnetic plate 305 to decrease. At the same time, the support spring 304 elastically recovers and drives the moving guide frame 401 to move, so that the moving magnetic plate 305 can contact the moving guide frame 401 during the movement. The squeezing plate 502 squeezes the water storage bladder 501, causing the water in the water storage bladder 501 to be sprayed out through the telescopic water outlet pipe 503 onto the surface of the wind turbine blade 1. As the wind turbine blade 1 rotates, the water is thrown outward in the direction of rotation, which allows the water flow to wash the front and back of the wind turbine blade 1. Then, the water is thrown out along the outer edge of the wind turbine blade 1 in the direction of the swing of the wind turbine blade 1. During the throwing process, the outer edge of the wind turbine blade 1 can be cleaned by the water flow. By setting a fixed support plate 301, a movable slide bar 303, a support spring 304, a movable magnetic plate 305, a support fixing plate 306, an electromagnetic plate 307, a movable guide frame 401, a lifting limit rod 402, a compression spring 403, a movable cleaning frame 404, a fixed rod 405, a cleaning roller 406, a water storage bladder 1 501, a compression plate 502, a telescopic water outlet pipe 503, a connecting pipe 504, a water storage bladder 2 505, and a water inlet pipe 506 on the wind turbine blade 1, the weight near the outer side of the wind turbine blade 1 can be effectively increased, providing more centrifugal force when the wind turbine blade 1 rotates, and accelerating the rotation speed of the wind turbine blade 1. When the wind turbine blade 1 rotates as the wind turbine operates, the electromagnetic plate 307 is disconnected, causing the magnetic force between the electromagnetic plate 307 and the moving magnetic plate 305 to decrease. At this time, the moving slide bar 303 and the support spring 304 push the moving guide frame 401 to move outward. During the movement of the moving guide frame 401, the cleaning roller 406 at the bottom of the moving guide frame 401 continuously contacts the surface of the wind turbine blade 1 and rolls on the surface of the wind turbine blade 1. This can remove the dust adhering to the surface of the wind turbine blade 1, preventing dirt from adhering to the surface of the wind turbine blade 1 during subsequent water cleaning. At the same time, due to the compression spring 403, the cleaning roller 406 can perform cleaning work along the arc surface of the wind turbine blade 1.
