Description

[0002] In recent years, wind power has played an important role in building a low-carbon, clean, and sustainable new energy system; however, the operation and maintenance costs of wind power have remained high, mainly consisting of tower cleaning, flaw detection, rust removal, and inspection of the turbine head at the top of the tower. Currently, specialized cleaning robots are typically used to clean the body of wind turbine towers.

[0003] In existing technologies, although cleaning robots can operate under electric power, their small size means they have limited power reserves. A portion of the power is used to move the robot on the tower, while the other portion is used for cleaning. This results in the battery being consumed too quickly. Consequently, the robot may not be able to clean efficiently while moving, or it may be unable to complete the cleaning of the entire tower body due to insufficient power when it has moved halfway through the tower.

[0047] Reference Figures 1 to 4As shown, a tower cleaning robot, used in practical applications to clean the surface of wind turbine towers, includes a housing 1, several climbing mechanisms 2 disposed within the housing 1, and a cleaning mechanism 3 connected to the housing 1. Specifically, the housing 1 is an annular structure adapted to the tower body, and the housing 1 covers the tower body. The several climbing mechanisms 2 are fixedly disposed within the housing 1 and arranged in a uniform circumferential array within the housing 1, and are used to drive the housing 1 to climb and move on the tower. The cleaning mechanism 3 is an arc-shaped structure adapted to the tower body, disposed at the bottom end of the housing 1 and movably connected to the housing 1, and is used to clean the tower body. That is, by driving the several climbing mechanisms 2, the housing is moved on the tower, and as the housing moves, the cleaning mechanism 3 cleans the tower body.

[0048] More specifically, the housing 1 consists of an internally hollow annular shell 11 and a cap 12 adapted to the annular shell 11. The cap 12 is detachably connected to the annular shell 11 by bolts. Several support columns 13 are provided on the top of the annular shell 11. A gap is formed between the annular shell 11 and the cap 12 through the support of the several support columns 13, so that the components installed in the housing 1 can be ventilated and dissipated.

[0049] In some preferred embodiments, the number of climbing mechanisms 2 is three. On the one hand, the three climbing mechanisms 2 form a triangular clamp on the tower body, and the friction between the climbing mechanism 2 and the tower body enables the climbing mechanism 2 to drive the entire device to move stably on the tower body, preventing slippage and distributing load stress, thereby improving the stability of the robot's movement on the tower. On the other hand, if one of the climbing mechanisms 2 is damaged or stops working, the remaining climbing mechanisms 2 can still continue to work, ensuring work efficiency.

[0050] In this embodiment, for ease of explanation, the climbing mechanism 2 is described as a single climbing mechanism 2. The climbing mechanism 2 includes a driver 21, a magnetic roller 22 connected to the driver 21, and an independent power supply 23 connected to the driver 21. The driver 21 is fixedly installed inside the housing 1. Preferably, the driver 21 is an eccentric motor. For example, the eccentric motor includes components such as an eccentric wheel, a rotor, and a drive shaft. It drives the rotor to rotate through the centrifugal force generated by the rotation of the eccentric wheel, thereby driving the drive shaft to rotate. This eliminates the complex transmission mechanism (such as gear sets or pulleys) of traditional motors, improving structural compactness and reducing its weight. The magnetic roller 22 is fixedly connected to the driver 21, and the rotating surface of the magnetic roller 22 is in contact with the tower body. Under the action of the driver 21, the magnetic roller 22 can continuously adhere to the tower and rotate, thereby driving the entire device to climb on the tower. That is, the center of the magnetic roller 22 is fixedly connected to the transmission shaft in the driver 21. By activating the driver 21, the magnetic roller 22 can be driven to continuously adhere to the tower body and rotate, further reducing the possibility of the climbing mechanism 2 sliding on the tower. Preferably, the magnetic roller 22 consists of an outer wheel and an inner support (not shown in the figure). By covering the inner support with the outer wheel, a roller-like structure is formed. The outer wheel is made of rubber magnetic material, for example, a mixture of ferrite magnetic powder and synthetic rubber, which has flexibility and torsion, allowing the outer wheel to continuously adhere to the tower while reducing weight. The inner support is made of rigid plastic to reduce the overall weight of the magnetic roller 22. The independent power supply 23 is disposed inside the housing 1 and located on one side of the driver 21. The driver 21 is electrically connected to the independent power supply 23 and is used to supply power to the driver 21.

[0051] In some preferred embodiments, a photovoltaic panel is also laid on the cap 12, and the photovoltaic panel is electrically connected to the independent power source 23, that is, the independent power source 23 can be charged through the photovoltaic panel to extend the battery's usage time.

[0052] In this embodiment, the cleaning mechanism 3 includes a water tank 31, a magnetic adhesive patch 32 disposed on the water tank 31, and a brush plate 33 disposed on the magnetic adhesive patch 32. Specifically, the water tank 31 is disposed at the bottom end of the housing 1. The water tank 31 has an arc-shaped box structure, and one side of it contacts the tower body, that is, the arc side with the smaller diameter of the water tank 31 contacts the tower body, so that the water tank 31 can fit against the surface of the tower body. The water tank 31 is used to fill the cleaning fluid for cleaning the tower body. The side of the water tank 31 that contacts the tower body also has several liquid outlet holes. The cleaning fluid in the water tank 31 flows to the tower body through the liquid outlet holes. In some embodiments, the flow rate and flow of the cleaning fluid can be adjusted by changing the size of the liquid outlet holes. For example, when the tower body is long, the flow rate of the cleaning fluid can be slowed down by reducing the orifice diameter of the liquid outlet holes, so as to save the amount of cleaning fluid used in the water tank 31. The magnetic adhesive patch 32 is fixedly mounted on the water tank 31 on one side of the liquid outlet to increase the adsorption capacity of the water tank and reduce the possibility of the water tank 31 sliding on the tower due to gravity after being filled with cleaning liquid. Preferably, the magnetic adhesive patch 32 is made of rubber magnetic material. The brush plate 33 is disposed on the magnetic adhesive patch 32, and the brush plate 33 is a plate-shaped structure adapted to the magnetic adhesive patch 32. The brush plate 33 is used to clean the tower, and the magnetic adhesive patch 32 allows the brush plate 33 to adhere tightly to the tower.

[0053] More specifically, the cleaning mechanism 3 also includes a linkage component 34 connected to the water tank 31. The linkage component 34 is disposed between the housing 1 and the water tank 31. The top end of the linkage component 34 is fixedly connected to the housing 1, and the bottom end is fixedly connected to the water tank 31. That is, the water tank 31 and the housing 1 are connected through the linkage component 34. The linkage component 34 is used to rotate the water tank 31, so that the cleaning liquid can flow more evenly onto the tower, thereby improving the cleaning efficiency.

[0054] In this embodiment, the linkage component 34 includes a connecting ring 341, a movable ring 342 connected to the connecting ring 341, and a transmission module 343. The connecting ring 341 is fixedly disposed at the bottom end of the housing 1, and the opening side of the connecting ring 341 is recessed inward to form a groove. The movable ring 342 is fixedly disposed at the top end of the water tank 31, and the movable ring 342 is rotatably disposed within the connecting ring 341. That is, the side of the movable ring 342 near the connecting ring 341 protrudes outward to form a flange, and the flange is rotatably disposed within the groove, so that the groove restricts the flange, allowing the movable ring 342 to rotate within the connecting ring 341 without falling off. In other words, the housing 1 and the water tank 31 are rotatably connected through the connecting ring 341 and the movable ring 342. One end of the transmission module 343 is connected to the drive shaft of the driver 21 in the climbing mechanism 2, and the other end is connected to the movable ring 342. The driver 21 is activated to drive the movable ring 342 to rotate, thereby driving the water tank 31 to rotate. That is, while the climbing mechanism 2 drives the casing 1 to move on the tower, it drives the cleaning mechanism 3 to clean the tower.

[0055] More specifically, the transmission module 343 includes a first gear 3431, a second gear 3432 connected to the first gear 3431, a rotating rod 3433 connected to the second gear 3432, and an internal gear ring 3434 connected to the rotating rod 3433. Specifically, the first gear 3431 is fixedly mounted on the transmission shaft of the driver 21, and starting the driver 21 can drive the first gear 3431 to rotate. The second gear 3432 is perpendicular to the first gear 3431 and meshes with it; the rotation of the first gear 3431 can drive the second gear 3432 to rotate simultaneously. The rotating rod 3433 is rotatably mounted on the housing 1, with one end fixedly connected to the second gear 3432, and the other end penetrating the bottom of the housing 1 and having a transmission gear. That is, when the second gear 3432 rotates, the rotating rod 3433 drives the transmission gear to rotate. The internal gear ring 3434 is fixedly mounted on the movable ring 342, and the internal gear ring 3434 is meshed with the transmission gear. That is, by starting the driver 21, the internal gear ring 3434 is driven to rotate under the action of the first gear 3431, the second gear 3432 and the rotating rod 3433, thereby causing the movable ring 342 to rotate, which in turn causes the water tank 31 to rotate on the tower. In other words, when the driver 21 drives the magnetic roller 22 to rotate, thereby causing the casing 1 to move on the tower, the transmission module 343 also drives the water tank 31 to rotate on the tower, thereby causing the brush plate 33 to perform a brushing operation around the tower.

[0056] In this embodiment, by setting several drive mechanisms inside the housing 1 to move the housing 1 on the tower, and under the action of the linkage component 34 in the cleaning mechanism 3, the drive mechanism moves the housing 1 while the cleaning mechanism 3 cleans the tower body. That is, the battery carried by the robot only needs to power the drive mechanism to realize the movement and cleaning of the entire robot on the tower. This solves the problem in the prior art where the battery carried by the cleaning robot is used for both movement and cleaning at the same time, resulting in excessive power consumption and inability to clean the entire tower body. This achieves the technical effect of reducing power consumption and improving resource utilization efficiency.

[0057] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
