Description

Technical Field

[0001] The present invention relates to the technical field of wind turbine generator maintenance equipment, and in particular to an automatic cleaning device for a wind turbine tower. Background Art

[0002] Wind power generation refers to the conversion of wind's kinetic energy into electrical energy. The device required for wind power generation is called a wind turbine, which can be roughly divided into three parts: the wind wheel, the generator and the tower. During use, the outer wall of the wind turbine tower is exposed to the natural environment for a long time, which will accumulate dust, which may cause corrosion to the tower and damage the outer wall of the tower. As a result, the outer wall of the tower needs to be cleaned regularly.

[0003] The existing cleaning methods include manual, robot, and cleaning device cleaning. Manual cleaning is done by workers hanging ropes from above the wind turbine to clean the tower arm. This cleaning method will not guarantee the personal safety of the workers, and the cleaning cost is also very high. Robot cleaning is done by a climbing robot driving a water tank and cleaning equipment for cleaning. However, the robot cannot cover the circumference of the tower wall, and it is inevitable that some areas will be missed during cleaning. A cleaning device, such as the Chinese patent with publication number CN218624530U, discloses a wind turbine tower cleaning device. By starting the No. 1 motor to drive the No. 1 gear to rotate, the No. 1 gear drives the teeth to rotate, so that the semicircular plate rotates between the No. 1 and No. 2 friction rings, and the brush plate rotates, so as to effectively clean the dirt on the surface of the wind turbine tower, and then start the No. 2 motor to drive the No. 3 gear to rotate, and the No. 3 gear It drives the No. 2 gear to rotate, and the No. 2 gear drives the rotating shaft to rotate between the two frames, and at the same time drives the rubber wheel to rotate and resist the surface of the wind turbine tower, so that the device can climb on the surface of the wind turbine tower. However, in actual use, due to the thicker diameter of the bottom of the tower, the volume of the semicircular plate, brush plate, and resistance ring will be larger. Coupled with the superimposed weight of the water storage tank, motor, etc., the device will be very heavy, which will lead to manual transportation and installation difficulties. At the same time, the power required for the device to climb must be sufficient, otherwise the device may not be driven to rise. In addition, the rubber wheel is installed on the semicircular plate, but in fact the tower is a cone, with a thin top and a thick bottom. When the rubber wheel rises to a certain height, it will not be able to contact the outer wall of the tower, further leading to the disadvantage that the device cannot be moved up. Therefore, the present application provides an automatic cleaning device for wind turbine towers to meet the needs. Summary of the Invention

In addition, the combined weight of the water storage tank, motor, etc. makes the device very heavy, which will lead to difficulties in manual handling and installation. At the same time, the device will require sufficient power when climbing, otherwise it may not be able to drive the device to rise. In addition, the rubber wheel is installed on the semicircular plate, but in fact the tower is a cone, with a thin top and a thick bottom.

[0016] Compared with the prior art, the present invention has at least the following beneficial effects:

[0017] In the above scheme, the mounting bracket, the cleaning assembly and the auxiliary assembly are arranged in coordination. During use, the first bolt is first tightened to release the limit of the threaded sleeve and the first connecting cylinder, and the first connecting cylinder and the first reinforcing rod are pulled away from each other, thereby causing the rotating column to rotate in the second connecting cylinder, and then the mounting plate is put on the tower, so that the first connecting cylinder and the first reinforcing rod are close to each other again, and the first bolt is restored to its original position, thereby limiting the mounting bracket and the cleaning assembly, and causing the roller brush to conflict with the outer wall of the tower. When the mounting plate moves upward, the remote control switch is controlled to cause the micro vacuum pump to extract the gas in the auxiliary assembly, thereby causing the air bag and the rubber tube to be tightened at the same time, so that the mounting plates are close to each other, and at the same time, the connecting assembly can slide into the second The mounting tube and the first mounting tube will further make the roller brush always keep in contact with the outer wall of the tower. When the mounting plate rotates, the roller brush will roll on the outer wall of the tower and clean the dust. When encountering lumps during the cleaning process, the roller brush will be squeezed by the lumps, and the first L-shaped rod will move, which will further make the first spring pull the limiting circle to move, and at the same time make the scraper and the lumps on the outer wall of the tower be scraped off, and the brush will sweep away the residue and floating dust adsorbed on the outer wall of the tower. Compared with the existing cleaning device, the present invention reduces the overall weight of the device, reduces the labor burden of the workers, and facilitates the overall lifting of the device. At the same time, the size can be adjusted according to the shape of the tower, so that the cleaning component can be matched with the tower for use, thereby improving the cleaning work of the tower.

[0018] By setting up a guide assembly, when in use, the rubber wheel will contact the outer wall of the tower. When the mounting plate rises, the rebound of the second spring will drive the rubber wheel to move, which will in turn extend the telescopic rod portion in the first telescopic rod outward, so that the rubber wheel always keeps in contact with the outer wall of the tower, and further guides the mounting plate to prevent the mounting plate from tilting due to uneven force. Compared with the existing cleaning device, the rubber wheel in the present invention can always keep in contact with the tower, and improves the stability of the mounting plate and the cleaning assembly.

[0019] By setting up a rotating assembly, during use, the rotation of the motor will cause the output shaft to drive the gear to rotate, the gear will cause the meshing outer ring gear to rotate, and at the same time will cause the slider to slide in the annular groove. The rotation of the outer ring gear will cause the second telescopic rod to drive the mounting plate to rotate, and then the cleaning assembly will rotate. At the same time, when the mounting plates approach each other, the telescopic rod part of the second telescopic rod will move with the mounting plates, thereby achieving the basic function of driving the mounting plates to rotate and avoiding interference with the approach of the mounting plates.

A motor 98 is installed on the outer disk 96. A gear 97 is installed on the output shaft of the motor 98. The gear 97 is meshed with the outer ring gear 91. The outer diameter of the outer disk 96 is larger than the outer diameter of the outer ring gear 91. The power line of the motor 98 is electrically connected to a remote control switch and a battery pack. This is a prior art and is not shown in the figure of the present invention.

[0050] By setting up the rotating assembly 9, during use, the rotation of the motor 98 will cause the output shaft to drive the gear 97 to rotate, and the gear 97 will cause the meshing outer ring gear 91 to rotate, and at the same time, the slider 94 will slide in the annular groove 93. The rotation of the outer ring gear 91 will cause the second telescopic rod 92 to drive the mounting plate 1 to rotate, and then the cleaning assembly 2 will rotate. At the same time, when the mounting plates 1 approach each other, the telescopic rod portion of the second telescopic rod 92 will move with the mounting plate 1, thereby achieving the basic function of driving the mounting plate 1 to rotate and avoiding interference with the approach of the mounting plate 1.

[0051] The technical solution provided by the present invention is arranged in coordination with the mounting bracket, the cleaning assembly, and the auxiliary assembly. During use, the first bolt is first screwed to release the limit of the threaded sleeve and the first connecting cylinder, and the first connecting cylinder and the first reinforcing rod are pulled away from each other, thereby causing the rotating column to rotate in the second connecting cylinder. Thereafter, the mounting plate is put on the tower, so that the first connecting cylinder and the first reinforcing rod are brought close to each other again, and the first bolt is restored to its original position, thereby limiting the mounting bracket and the cleaning assembly, and causing the roller brush to conflict with the outer wall of the tower. When the mounting plate moves upward, the remote control switch is controlled to cause the micro vacuum pump to extract the gas in the auxiliary assembly, thereby causing the air bag and the rubber tube to be tightened at the same time, so that the mounting plates are brought close to each other, and the connecting assembly can slide. Into the second mounting tube and the first mounting tube, the roller brush drum will further keep in contact with the outer wall of the tower at all times. When the mounting plate is rotating, the roller brush drum will roll on the outer wall of the tower and clean the dust. When encountering lumps during the cleaning process, the roller brush drum will be squeezed by the lumps, and the first L-shaped rod will move, which will further cause the first spring to pull the limiting circle to move, and at the same time, the scraper and the lumps on the outer wall of the tower will be scraped off, and the brush will sweep away the residue and floating dust adsorbed on the outer wall of the tower. Compared with the existing cleaning device, the present invention reduces the overall weight of the device, reduces the labor burden of the workers, and facilitates the overall lifting of the device. At the same time, the size can be adjusted according to the shape of the tower, so that the cleaning component can be matched with the tower for use, thereby improving the cleaning work of the tower.

[0052] By setting up a guide assembly, when in use, the rubber wheel will contact the outer wall of the tower. When the mounting plate rises, the rebound of the second spring will drive the rubber wheel to move, which will in turn extend the telescopic rod portion in the first telescopic rod outward, so that the rubber wheel always keeps in contact with the outer wall of the tower, and further guides the mounting plate to prevent the mounting plate from tilting due to uneven force. Compared with the existing cleaning device, the rubber wheel in the present invention can always keep in contact with the tower, and improves the stability of the mounting plate and the cleaning assembly.

[0053] By setting up a rotating assembly, during use, the rotation of the motor will cause the output shaft to drive the gear to rotate, the gear will cause the meshing outer ring gear to rotate, and at the same time will cause the slider to slide in the annular groove. The rotation of the outer ring gear will cause the second telescopic rod to drive the mounting plate to rotate, and then the cleaning assembly will rotate. At the same time, when the mounting plates approach each other, the telescopic rod part of the second telescopic rod will move with the mounting plates, thereby achieving the basic function of driving the mounting plates to rotate and avoiding interference with the approach of the mounting plates.

[0054] The present invention encompasses any alternatives, modifications, equivalents, and solutions that fall within the spirit and scope of the present invention. While specific details are described in detail in the preferred embodiments of the present invention to provide a thorough understanding of the present invention, those skilled in the art will be able to fully understand the present invention without these detailed descriptions. Furthermore, to avoid unnecessary confusion regarding the essence of the present invention, well-known methods, processes, procedures, components, and circuits have not been described in detail.

[0056] The above are only preferred embodiments of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
