Description

Technical Field

[0001] This application relates to the field of cleaning equipment, and in particular to a cleaning device for the outer surface of a large tower. Background Technology

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives a rotor to rotate and ultimately outputs alternating current (AC). A wind turbine typically consists of components such as fan blades, a generator (including the generator assembly), a steering gear (tail fin), a tower, a speed-limiting safety mechanism, and an energy storage device.

[0003] Because towers are exposed to the natural environment for extended periods, their outer walls accumulate a large amount of dust, necessitating regular cleaning. However, due to the tower's height and smooth surface, cleaning is inconvenient. Therefore, the inventor provides a large-scale tower exterior surface cleaning device. Summary of the Invention

[0004] To facilitate the cleaning of wind power generation towers, this application provides a large tower outer surface cleaning device.

[0005] The large tower outer surface cleaning device provided in this application adopts the following technical solution:

[0006] A large tower exterior surface cleaning device includes a movable frame, a wind turbine, and rotating cleaning components. The movable frame is coaxially sleeved on the outside of the tower, and a drive assembly for driving the movable frame to move up and down on the tower is provided on the movable frame. The wind turbine is coaxially rotatably mounted on the movable frame, and the rotating cleaning components are rotatably mounted on the movable frame for cleaning dust on the tower. Multiple rotating cleaning components are arranged around the tower, and the rotating cleaning components are linked with the wind turbine.

[0007] By adopting the above technical solution, a movable frame is set on the outside of the tower, and a wind turbine and a rotating cleaning component are set on the movable frame. In the natural environment, the wind energy is relatively abundant where wind turbines are installed. After the wind blows onto the wind turbine, the wind turbine will rotate and drive the rotating cleaning component to rotate and clean the outer wall of the tower. At the same time, the drive component drives the movable frame to move up and down along the tower, so that the outer surface of the tower can be automatically cleaned.

[0008] Optionally, the outer side of the wind turbine is covered with an outer shell, which is coaxially rotatably mounted on the movable frame. A tail rudder for controlling the direction of the outer shell is fixed on one side of the outer shell. A wind tunnel is opened on one side of the outer shell away from the tail rudder, and wind blows in from the wind tunnel to drive the wind turbine to rotate.

[0009] By adopting the above technical solutions, a wind tunnel is set on the outer shell, which can guide the wind, increase the force of the wind on the wind turbine, and improve the energy utilization rate; a tail rudder is set on the outer shell, which can keep the wind tunnel facing the direction of the wind when there is wind, thereby improving the wind tunnel's air intake rate.

[0010] Optionally, a gear ring is coaxially fixed on the impeller, the rotating cleaning component is configured as a brush, a driven gear is coaxially fixed on the rotating cleaning component, and a gear set for transmission is provided between the gear ring and the driven gear.

[0011] By adopting the above technical solution, a gear ring is fixed on the wind turbine, and the power of the wind turbine is transmitted to the rotating cleaning component through the gear ring, gear set and driven gear.

[0012] Optionally, the drive assembly includes a pressure roller, a pusher for driving the pressure roller closer to or away from the tower, and a drive for driving the pressure roller to rotate. Multiple sets of pressure rollers are arranged on the moving frame along the circumferential direction of the tower.

[0013] By adopting the above technical solution, multiple sets of pressure rollers are set on the mobile frame. The pressure rollers press against the outer wall of the tower under the action of the pushing component. The pressure rollers are driven to rotate by the driving component, which can drive the entire structure to move up and down along the tower, thereby completing the cleaning of the tower.

[0014] Optionally, the pressure roller is inclined, and when the pressure roller rotates, it drives the movable frame to spiral up or spiral down along the tower.

[0015] By adopting the above technical solution, the pressure roller is tilted. When the pressure roller rotates, it can drive the moving frame to rise or fall along the tower, so that the rotating cleaning component can clean the tower more thoroughly.

[0016] Optionally, a central gear meshing with the driven gear is rotatably fixed on the movable frame, and the power of the gear set is transmitted to the driven gear through the central gear; a dial plate is rotatably mounted on the movable frame with the central gear as the center, and the driven gear is rotatably mounted on the dial plate; a dial groove is formed along the length direction on the dial plate, and a lever is provided at the output end of the pusher, the lever is inserted into the dial groove, and when the pusher drives the pressure roller to approach or move away from the tower, the lever moves the dial plate to rotate, causing the rotating cleaning component to approach or move away from the tower.

[0017] By adopting the above technical solution, since the tower has a tapered shape, if the position of the rotating cleaning component remains unchanged, the tower cannot be thoroughly cleaned. A central gear is set on the moving frame, and a lever is set around the central gear. When the lever rotates around the central gear, the driven gear can always mesh with the central gear for transmission. When the pusher drives the pressure roller to approach or move away from the tower, the lever can move the lever to follow the pressure roller, so that the rotating cleaning component can always be in contact with the tower for brushing.

[0018] Optionally, a backup power supply for supplying power to the drive assembly is installed on the mobile frame, and a generator is connected to the wind turbine for charging the backup power supply.

[0019] By adopting the above technical solution, the backup power supply can supply power to the drive components after a problem occurs in the power supply line to the drive components.

[0020] Optionally, the mobile frame is also equipped with photovoltaic panels for charging the backup power source.

[0021] In summary, this application includes at least one of the following beneficial technical effects:

[0022] 1. By setting a mobile frame on the outside of the tower, and installing a wind turbine and a rotating cleaning component on the mobile frame, wind energy is abundant in natural environments where wind turbines are installed. After the wind blows onto the wind turbine, the wind turbine will rotate, driving the rotating cleaning component to rotate and clean the outer wall of the tower. At the same time, the drive component drives the mobile frame to move up and down along the tower, thereby automatically cleaning the outer surface of the tower.

[0023] 2. By installing a wind tunnel on the outer shell, the wind tunnel can guide the wind, increase the force of the wind on the wind turbine, and improve the energy utilization rate. By installing a tail rudder on the outer shell, the wind tunnel can always be oriented towards the direction of the wind when there is wind, thereby increasing the wind tunnel's air intake rate.

[0024] 3. Since the tower has a tapered shape, if the position of the rotating cleaning component remains unchanged, the tower cannot be thoroughly cleaned. A central gear is installed on the moving frame, and a lever is installed that rotates around the central gear. When the lever rotates around the central gear, the driven gear can always mesh with the central gear for transmission. When the pusher drives the pressure roller to approach or move away from the tower, the lever can move the lever to follow the pressure roller, so that the rotating cleaning component can always be in contact with the tower for brushing.

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0030] This application discloses a large tower outer surface cleaning device, referring to... Figure 1 and Figure 2 The system includes a movable frame 1, a wind turbine 3, and a rotating cleaning component 4 for cleaning the exterior of the tower 01. The movable frame 1 is a ring-shaped frame that is coaxially fitted onto the outside of the tower 01. A drive assembly 2 for driving the movable frame 1 to move up and down on the tower 01 is provided on the movable frame 1. The wind turbine 3 is coaxially and rotatably mounted on the movable frame 1. A rotating cleaning component 4 is also rotatably mounted on the movable frame 1. Multiple rotating cleaning components 4 are evenly distributed along the circumference of the movable frame 1. The rotation axis of the rotating cleaning component 4 is parallel to the axis of the tower 01. The rotating cleaning component 4 is linked with the wind turbine 3. When the wind turbine 3 rotates, it drives the rotating cleaning component 4 to rotate and scrub the surface of the tower 01.

[0031] An outer casing 5 is provided on the outside of the wind turbine 3, and the outer casing 5 is rotatably mounted on the movable frame 1. A tail rudder 51 for controlling the direction of the outer casing 5 is fixed on one side of the outer casing 5. A wind tunnel 52 is provided through the side wall of the outer casing 5 away from the tail rudder 51, and the wind tunnel 52 is offset to one side of the outer casing 5. When the wind blows, the tail rudder 51 will be blown by the wind, causing the wind tunnel 52 to face the direction of the wind, and the wind will directly enter the wind tunnel 52 to drive the wind turbine 3 to rotate rapidly.

[0032] Reference Figure 2 and Figure 3 A gear ring 31 is coaxially fixed at the lower end of the impeller 3. The rotating cleaning component 4 is set as a brush. A driven gear 41 is coaxially fixed at the lower end of the rotating cleaning component 4. A gear set 32 ​​is set between the driven gear 41 and the gear ring 31. The gear ring 31 transmits power to the driven gear 41 through the gear set 32. The gear set 32 ​​is set with a suitable gear ratio so that the impeller 3 can drive the rotating cleaning component 4 to rotate even when the wind force is small.

[0033] The drive assembly 2 includes a pressure roller 21, a pusher 22, and a drive component 23 that drives the pressure roller 21 to rotate. The pusher 22 is an electric cylinder and is fixed to the moving frame 1 radially. The piston rod of the pusher 22 faces the tower 01. The pressure roller 21 is rotatably mounted on the end of the piston rod of the pusher 22 near the tower 01. The drive component 23 is a motor. The pressure roller 21 is coaxially fixed to the housing 5 of the drive component 23. The rotating shaft of the drive component 23 is fixed to the piston rod of the pusher 22. When the drive component 23 rotates, the housing 5 of the drive component 23 directly drives the pressure roller 21 to rotate. Multiple sets of pressure rollers 21, pushers 22, and driveers 23 are evenly distributed along the circumference of the movable frame 1. In use, multiple pushers 22 simultaneously drive the pressure rollers 21 to press against the tower 01, and the driveers 23 drive the pressure rollers 21 to rotate, which can drive the movable frame 1 to move up and down on the tower 01. During the raising and lowering of the movable frame 1, the pushers 22 extend or shorten according to the taper of the tower 01, so that the pressure rollers 21 always press against the tower 01.

[0034] The pressure roller 21 is installed at a certain angle along the axis of the pusher 22, so that when the pressure roller 21 rotates, it can drive the moving frame 1 to spiral up or down along the tower 01, thereby driving the rotating cleaning component 4 to clean the outer wall of the tower 01 in all directions.

[0035] A central gear 12 is rotatably mounted on the movable frame 1 between the driven gear 41 and the gear set 32. The axis of rotation of the central gear 12 is parallel to the axis of rotation of the driven gear 41, and the central gear 12 meshes with both the gear set 32 ​​and the driven gear 41. A lever plate 11 is rotatably mounted on the movable frame 1 with the central gear 12 as its center. The driven gear 41 and the rotating cleaning component 4 are rotatably mounted on the lever plate 11. When the lever plate 11 rotates around the central gear 12, it can drive the rotating cleaning component 4 to move closer to or away from the tower 01. A lever groove 111 is formed along the length of the lever plate 11. A lever rod 221 is welded and fixed to the piston rod of the pusher 22. The lever rod 221 is inserted into the lever groove 111. During the process of the pusher 22 driving the pressure roller 21 to press the tower 01, the lever rod 221 drives the rotating cleaning component 4 to move closer to or away from the tower 01.

[0036] A generator 7 is connected to the wind turbine 3, and a backup power supply 6 is installed on the mobile frame 1. The generator 7 is electrically connected to the backup power supply 6. When the wind turbine 3 rotates, it drives the generator 7 to charge the backup power supply 6. A photovoltaic panel 8 is installed on the outer casing 5, and it is electrically connected to the backup power supply 6. When there is sunlight, the photovoltaic panel 8 charges the backup power supply 6. In use, the drive assembly 2 can be powered by an external power source or by the backup power supply 6.

[0037] The implementation principle of a large tower outer surface cleaning device disclosed in this application is as follows: By setting a wind turbine 3 and a rotating cleaning component 4 on a mobile frame 1, the wind energy is abundant in the operating environment of the wind turbine 7. The wind can drive the wind turbine 3 to rotate. The energy of the wind turbine 3 rotation is transmitted to the rotating cleaning component 4 through the gear set 32, which drives the rotating cleaning component 4 to rotate and clean the outer wall of the tower 01. By setting a central gear 12 and a deflector 11, and installing the driven gear 41 and the rotating cleaning component 4 on the deflector 11, during the process of the pusher 22 driving the pressure roller 21 to press against the outer wall of the tower 01, the pusher 22 will drive the deflector 11 to rotate around the central gear 12, thereby driving the rotating cleaning component 4 to get closer to the tower 01, which can better clean the tower 01.

[0038] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
