[0079] Here, exemplary embodiments will be described in detail, and their examples are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0080] The technical solutions of the present application will be described in detail below with specific embodiments. These specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0081] To clearly understand the technical solutions of the present application, the solutions of the prior art will be introduced in detail first.

[0082] A wind turbine is a device that converts wind energy into electrical energy. It generally consists of a tower, nacelle, generator, gearbox, control system, blades, etc. The blades are used to capture wind energy and transfer mechanical energy to the generator through rotational motion, ultimately generating electrical energy. During use, the blades will encounter impurities such as dust, sand grains, and plant debris. These impurities will change the surface characteristics of the blades, increase air resistance, and reduce the power generation efficiency of the wind turbine. The automatic cleaning device for wind turbine blades is used to clean the impurities on the blades. Usually, cleaning blocks are connected to the automatic cleaning device for wind turbine blades through fasteners such as bolts and nuts, and then the impurities on the wind turbine blades are cleaned by the method of friction between the cleaning blocks and the blades.

[0083] Currently, during the long-term use of the cleaning blocks, the cleaning blocks will wear out, so the cleaning blocks need to be replaced regularly. During the disassembly of the cleaning blocks, it is necessary to loosen the fasteners one by one and remove the cleaning blocks; after replacing the new cleaning blocks, it is necessary to tighten the fasteners one by one to ensure their firm connection. The replacement process of the cleaning blocks is cumbersome and time-consuming, reducing the cleaning efficiency of the automatic cleaning device for wind turbine blades. Therefore, the current automatic cleaning device for wind turbine blades has the problem of a cumbersome cleaning block replacement process.

[0084] Therefore, in view of the problem in the prior art that the process of replacing the cleaning block in the automatic cleaning device for wind turbine blades is cumbersome, it is found in the research that in order to solve this problem, an automatic cleaning device for wind turbine blades that can flexibly replace the cleaning block needs to be designed: ① In order to enable the cleaning block to be flexibly replaced, a flexible connection mechanism can be set for the cleaning block and the connecting plate. This connection mechanism should not only ensure the tight connection between the cleaning block and the connecting plate, but also ensure that the cleaning block can be easily detached from the connecting plate when replacing the cleaning block. ② Set corresponding connection spaces on the cleaning block and the connecting plate according to this connection mechanism. ③ Connect this connection mechanism with external components so that the operator can regulate this connection mechanism through the external components, and then adjust the connection relationship between the cleaning block and the connecting plate.

[0085] Specifically:

[0086] The cleaning block and the connecting plate are connected by a connecting rod, and corresponding connection spaces are set on the cleaning block and the connecting plate according to the shape of the connecting rod. At the same time, the connecting rod is connected to an external handle, and the operator can operate the state of the connecting rod through the handle, and then adjust the connection state between the cleaning block and the connecting plate.

[0087] In the automatic cleaning device for wind turbine blades according to the embodiment of the present application, the second cleaning block and the second connecting plate are connected by an L-shaped rod. There is a movable groove on the second connecting plate, and a concave groove is provided on the second cleaning block. One end of the L-shaped rod is arranged in the movable groove, and the other end of the L-shaped rod is arranged in the concave groove. At the same time, the L-shaped rod is connected to an external handle through an elliptical block and a rotating rod. When disassembling the second cleaning block, the operator drives the handle, and the elliptical block no longer abuts against one end of the L-shaped rod, so that the other end of the L-shaped rod is pulled out from the concave groove, and the second cleaning block and the second connecting plate are disconnected; when installing the second cleaning block, the operator rotates the handle, and the elliptical block abuts against one end of the L-shaped rod, so that the other end of the L-shaped rod is inserted into the concave groove, and the second cleaning block and the second connecting plate are connected. Through such a setting, when replacing the second cleaning block, there is no need to disassemble and install multiple fasteners anymore. Only by rotating the handle can the connection relationship between the second cleaning block and the second connecting plate be adjusted, and the replacement process of the second cleaning block is simplified, improving the cleaning efficiency of the automatic cleaning device for wind turbine blades.

[0088] Based on the above creative discovery, the technical solution of the present application is proposed.

[0089] The embodiments of the present application will be introduced below with reference to the accompanying drawings of the specification.

[0090] Figure 1 The structural schematic diagram of the automatic cleaning device for wind turbine blades provided by the embodiment of the present application Figure 1 . As Figure 1As shown, in this embodiment, the automatic cleaning device for wind turbine blades includes: an operating table 100, a driving motor 200, a first support frame 300, a second support frame 400, two driving blocks 500, a first connecting plate 600, a first cleaning block 700, a second connecting plate 800, a second cleaning block 900, and two round rods 1000.

[0091] Specifically, the operating table 100 is the basic platform of the entire device, used to support and fix other components. The driving motor 200 is used to provide power for the automatic cleaning device of wind turbine blades, driving the driving block 500 to move along the moving groove 1001, thereby driving the first cleaning block 700 and the second cleaning block 900 to clean on the blade surface. The first support frame 300 and the second support frame 400 are used to support the blade. The first connecting plate 600 plays a role in connecting and supporting the first cleaning block 700, enabling the first cleaning block 700 to effectively perform the cleaning operation. The first cleaning block 700 and the second cleaning block 900 are used to remove impurities on the blade surface and clean the surface of the wind turbine blade. The second connecting plate 800 plays a role in connecting and supporting the second cleaning block 900. The round rod 1000 is used to connect and support the first connecting plate 600 and the second connecting plate 800 to ensure the stability of the second cleaning block 900 during the cleaning process.

[0092] One end of the first support frame 300 is connected to the first side surface of the operating table 100, and one end of the second support frame 400 is connected to the second side surface of the operating table 100, and the first side surface is parallel to the second side surface.

[0093] Specifically, one end of the first support frame 300 and one end of the second support frame 400 are respectively connected to the two side surfaces of the operating table 100. When cleaning the blade, the blade is placed on the other ends of the first support frame 300 and the second support frame 400, and the first support frame 300 and the second support frame 400 play a role in supporting the blade.

[0094] The driving motor 200 is arranged on the second side surface of the operating table 100, and the driving motor 200 is used to supply energy for the automatic cleaning device of wind turbine blades.

[0095] Specifically, the driving motor 200 is the power source of the entire automatic cleaning device for wind turbine blades. The driving motor 200 drives the driving block 500 to slide along the moving groove 1001 on the top of the operating table 100 through a transmission mechanism. The movement of the driving block 500 drives the first cleaning block 700 to perform a cleaning operation on the surface of the wind turbine blade.

[0096] Two moving grooves 1001 are arranged on the top of the operating table 100 along the first direction, and the first direction refers to the direction parallel to the setting direction of the first support frame 300 and the second support frame 400.

[0097] Specifically, the moving groove 1001 is used to provide a sliding path for the driving block 500, enabling the driving block 500 to move along the sliding path and ensuring that the driving block 500 does not deviate from the preset path during movement.

[0098] One end of each driving block 500 is respectively slidably connected to each moving groove 1001, and the other end of each driving block 500 is connected to the bottom of the first connecting plate 600. The top of the first connecting plate 600 is connected to the bottom of the first cleaning block 700.

[0099] Specifically, one end of the driving block 500 is slidably connected to the moving groove 1001 to ensure that the driving block 500 can move smoothly along the path of the moving groove 1001. The bottom of the first connecting plate 600 is connected to the driving block 500, and the top is connected to the first cleaning block 700. The first connecting plate 600 plays a role of connection and support, ensuring that the first cleaning block 700 can be stably installed on the driving block 500 and perform cleaning operations as the driving block 500 moves.

[0100] The bottom of each round rod 1000 is connected to the top of the first connecting plate 600, the top of each round rod 1000 is connected to the bottom of the second connecting plate 800, and the top of the second cleaning block 900 is connected to the bottom of the second connecting plate 800.

[0101] Specifically, the round rod 1000 plays a role of connection and support, ensuring the stable connection between the first connecting plate 600 and the second connecting plate 800. The round rod 1000 transmits the movement of the first connecting plate 600 to the second connecting plate 800, enabling the second cleaning block 900 to perform cleaning on the blade surface as the first connecting plate 600 moves. Through this connection, the first cleaning block 700 and the second cleaning block 900 can move synchronously, ensuring the continuity and effectiveness of the cleaning process.

[0102] The second connecting plate 800 is provided with a connecting rod 1100. The connecting rod 1100 is used to connect the second cleaning block 900 to the second connecting plate 800. When the second cleaning block 900 is disassembled, the connecting rod 1100 is in a tensioned state, and the second cleaning block 900 is in a connected state with the second connecting plate 800. The connecting rod 1100 is used to adjust from the tensioned state to the loosened state to disconnect the second cleaning block 900 from the second connecting plate 800; when the second cleaning block 900 is installed, the connecting rod 1100 is in a loosened state, and the second cleaning block 900 is in a disconnected state from the second connecting plate 800. The connecting rod 1100 is used to adjust from the loosened state to the tensioned state to connect the second cleaning block 900 to the second connecting plate 800.

[0103] Specifically, the connecting rod 1100 is used to fix the second cleaning block 900 to the second connecting plate 800. In the normal operating state, the connecting rod 1100 is in a tensioned state, ensuring a firm connection between the second cleaning block 900 and the second connecting plate 800, thereby ensuring that the second cleaning block 900 does not fall off or move during the cleaning process. When the second cleaning block 900 needs to be replaced, the connecting rod 1100 can be adjusted to a loose state, disconnecting the second cleaning block 900 from the second connecting plate 800. The connecting rod 1100 can be adjusted from a tensioned state to a loose state, and this adjustment mechanism ensures that the second cleaning block 900 can be quickly disassembled or installed, improving the maintenance efficiency and operation convenience.

[0104] An automatic cleaning device for a wind turbine blade provided in this embodiment uses a connecting rod to connect the second cleaning block and the second connecting plate. When the second cleaning block is disassembled, the connecting rod is adjusted from a tensioned state to a loose state, and the second cleaning block is disconnected from the second connecting plate; when the second cleaning block is installed, the connecting rod is adjusted from a loose state to a tensioned state, and the second cleaning block is connected to the second connecting plate. The automatic cleaning device for a wind turbine blade achieves the following technical effects: By the connecting rod, the connection state between the second cleaning block and the second connecting plate can be controlled. When replacing the second cleaning block, there is no need to disassemble and install multiple fasteners. Only by adjusting the state of the connecting rod can the second cleaning block be removed and installed. The replacement process of the second cleaning block is simplified, and the cleaning efficiency of the automatic cleaning device for a wind turbine blade is improved.

[0105] Figure 2 Structural schematic of the automatic cleaning device for a wind turbine blade provided in the embodiment of the present application Figure 2 As Figure 2 shown, on the basis of the Figure 1 embodiment, the automatic cleaning device for a wind turbine blade is described in detail.

[0106] The second connecting plate 800 is provided with a movable groove 8001, and the connecting rod 1100 includes two L-shaped rods 8006.

[0107] Specifically, the movable groove 8001 is used to provide a moving space for the two L-shaped rods 8006. By moving the two L-shaped rods 8006 in the movable groove 8001, the second cleaning block 900 can be fixed to the second connecting plate 800 or disconnected.

[0108] Inside the movable slot 8001, there is a fixed connection with a sleeve 8002. Inside the sleeve 8002, there is a rotatably connected first rotating rod 8003. The other end of the first rotating rod 8003 is connected to one side of the elliptical block 8004. The other side of the elliptical block 8004 is connected to one end of the second rotating rod 8005. Both ends of the elliptical block 8004 are in contact with two L-shaped rods 8006 respectively. At the bottom inside the movable slot 8001, there are two through slots 8007. The elliptical block 8004 is used to move the two L-shaped rods 8006 in the corresponding through slots 8007.

[0109] Specifically, the sleeve 8002 is used to support and fix the first rotating rod 8003 to ensure that the first rotating rod 8003 can rotate freely inside the sleeve 8002. The first rotating rod 8003 rotates inside the sleeve 8002 to transmit the rotational motion to the elliptical block 8004. By rotating the first rotating rod 8003, the elliptical block 8004 can be driven to rotate. The elliptical block 8004 can convert its own rotational motion into the linear motion of the L-shaped rod 8006, thereby pushing the L-shaped rod 8006 to move in the through slot 8007. The second rotating rod 8005 is used to transmit the rotational motion of the elliptical block 8004 to other components to ensure the coordinated operation of the connection and disconnection mechanism. The L-shaped rod 8006 moves in the through slot 8007 under the push of the elliptical block 8004, thereby realizing the connection and disconnection between the second cleaning block 900 and the second connecting plate 800. The through slot 8007 provides a controlled movement path for the L-shaped rod 8006 to ensure that the L-shaped rod 8006 can move within a preset range.

[0110] The technical effect of this embodiment is that the design inside the movable slot enables the L-shaped rod to move freely in the through slot, thereby quickly realizing the connection and disconnection operation between the second cleaning block and the second connecting plate. This design makes the disassembly and installation of the second cleaning block more convenient, enables the automatic cleaning device for wind turbine blades to replace and adjust the second cleaning block more quickly, and thus improves the cleaning efficiency.

[0111] Figure 3 Structural schematic of the automatic cleaning device for wind turbine blades provided by the embodiment of the present application Figure 3 As Figure 3 shown, on the basis of the Figure 1 and Figure 2 embodiments, the automatic cleaning device for wind turbine blades is described in detail.

[0112] Each L-shaped rod 8006 is provided with a limiting hole 8008. A limiting rod 8009 is slidably connected in the limiting hole 8008. Both ends of the limiting rod 8009 are connected to the inside of the movable slot 8001.

[0113] Specifically, the limiting rod 8009 is slidably connected in the limiting hole 8008. By connecting to the inside of the movable groove 8001, the movement range of the L-shaped rod 8006 is restricted, ensuring that the L-shaped rod 8006 moves within a preset range and preventing deviation. The limiting rod 8009 provides additional support and stability through its connection to the inside of the movable groove 8001, ensuring that the L-shaped rod 8006 remains stable during movement and does not wobble or deviate from the preset trajectory.

[0114] A return spring 8010 is sleeved on the outer side of the limiting rod 8009, and both ends of the return spring 8010 are respectively connected to the two L-shaped rods 8006.

[0115] Specifically, when the L-shaped rod 8006 moves under the action of an external force, the return spring 8010 can provide a reverse elastic force, enabling the L-shaped rod 8006 to automatically return to its initial position after the external force disappears. The return spring 8010 ensures that the L-shaped rod 8006 remains under control during movement by providing a stable elastic force, preventing excessive movement or deviation, thereby improving the stability and reliability of the device.

[0116] A concave groove 9001 is provided at the top of the second cleaning block 900.

[0117] Specifically, the concave groove 9001 is used to provide an interface for insertion and extraction. When the major axis of the elliptical block 8004 is in the horizontal direction, the L-shaped rod 8006 can be inserted into the concave groove 9001, thus connecting the second connecting plate 800 and the second cleaning block 900; when the major axis of the elliptical block 8004 is in the vertical direction, the L-shaped rod 8006 can be pulled out of the concave groove 9001, thus disconnecting the second connecting plate 800 and the second cleaning block 900, realizing the quick installation and disassembly of the second cleaning block 900.

[0118] When the major axis of the elliptical block 8004 is in the horizontal direction, the elliptical block 8004 is used to move the two L-shaped rods 8006 away from each other, and the L-shaped rod 8006 is used to insert into the concave groove 9001 to connect the second connecting plate 800 and the second cleaning block 900.

[0119] Specifically, through the rotation of the elliptical block 8004, the two L-shaped rods 8006 move outward, thereby inserting into the concave groove 9001 at the top of the second cleaning block 900, realizing the connection between the second connecting plate 800 and the second cleaning block 900, and ensuring that the second cleaning block 900 is tightly connected to the second connecting plate 800 during the cleaning operation.

[0120] When the major axis of the elliptical block 8004 is in the vertical direction, the elliptical block 8004 is used to bring the two L-shaped rods 8006 closer, and the L-shaped rods 8006 are used to be pulled out from the concave groove 9001, so that the second connecting plate 800 and the second cleaning block 900 are in an unconnected state.

[0121] Specifically, through the rotation of the elliptical block 8004, the two L-shaped rods 8006 move inward, so as to be pulled out from the concave groove 9001 at the top of the second cleaning block 900, realizing the separation of the second connecting plate 800 and the second cleaning block 900, and facilitating the disassembly and replacement of the second cleaning block 900.

[0122] The technical effect of this embodiment is that by providing a limit hole on the L-shaped rod and slidingly connecting a limit rod in the limit hole, the movement range of the L-shaped rod can be effectively controlled. The design of the limit rod ensures that the L-shaped rod moves within a preset trajectory, avoiding excessive movement or deviation. The limit rod is connected to the inside of the movable groove, providing additional support and stability. This can ensure that the L-shaped rod remains stable during movement, without shaking or deviating from the preset trajectory, improving the overall stability of the device; when the L-shaped rod is moved by an external force during movement, the return spring provides a reverse elastic force, so that the L-shaped rod automatically returns to the initial position after the external force disappears. This automatic reset function ensures that the L-shaped rod can quickly return to the original position, avoiding failures caused by position deviation; by providing a concave groove at the top of the second cleaning block and using the rotation of the elliptical block to control the insertion and extraction of the L-shaped rod, the quick connection and separation of the second connecting plate and the second cleaning block are realized, thus simplifying the installation and disassembly process of the second cleaning block and improving the operation efficiency and maintenance convenience.

[0124] embodiment, the automatic cleaning device for wind turbine blades is described in detail.

[0125] Specifically, through the fixation of the cover plate 8011 and the guidance of the insertion hole 8012, the second rotating rod 8005 can stably pass through the cover plate 8011 and be connected to the handle 8013, so that the operator can rotate the second rotating rod 8005 through the handle 8013, and then control the rotation of the elliptical block 8004 to realize the movement of the L-shaped rod 8006 and the connection or separation of the second cleaning block 900.

[0126] The technical effect of this embodiment is as follows: By fixedly connecting a cover plate in the movable slot and providing an insertion hole in the cover plate, the other end of the second rotating rod can stably pass through the cover plate and be connected to the handle, facilitating the operator to rotate the second rotating rod through the handle, thereby controlling the rotation of the elliptical block, realizing the movement of the L-shaped rod and the connection or separation of the second cleaning block. This design improves the convenience and accuracy of operation and ensures the simplicity of maintaining the cleaning device.

[0132] The automatic wind turbine blade cleaning device further includes: a tension spring 8016.

[0133] Specifically, the tension spring 8016 is used to provide an elastic restoring force to ensure that the movable block 8015 can automatically reset inside the square groove 8014. By connecting the movable block 8015 and the inside of the square groove 8014, the tension spring 8016 can generate a pulling force to restore the movable block 8015 to its initial position after it is pulled or moved.

[0134] One end of the tension spring 8016 is connected to the movable block 8015, and the other end of the tension spring 8016 is connected to the inside of the square groove 8014.

[0135] Specifically, one end of the tension spring 8016 is connected to the movable block 8015, and the other end is connected to the inside of the square groove 8014. When the movable block 8015 is pulled or moved, the tension spring 8016 can provide an elastic restoring force to enable the movable block 8015 to automatically reset to the initial position after the operation is completed. This design ensures the stability of the movable block 8015 within the square groove 8014 and improves the convenience and accuracy of the operation.

[0136] A limiting groove 8017 is provided inside the square groove 8014.

[0137] Specifically, a limiting groove 8017 is provided inside the square groove 8014 to provide a guiding and limiting mechanism, enabling the movable block 8015 to stay on a preset track during the sliding process within the square groove 8014, preventing the movable block 8015 from deviating or making unnecessary movements, thereby ensuring its stability and accuracy.

[0138] A sliding member 8018 is provided outside the movable block 8015, and the movable block 8015 is used to slidably connect with the limiting groove 8017 through the sliding member 8018.

[0139] Specifically, through the cooperation of the sliding member 8018 and the limiting groove 8017, smooth sliding of the movable block 8015 within the square groove 8014 is achieved. The sliding member 8018 provides a low-friction contact surface to ensure that the movable block 8015 can smoothly move along the limiting groove 8017, thereby improving the convenience and accuracy of the operation.
