Description

Technical Field

[0001] The invention relates to the technical field of tower wall cleaning, and in particular to a tower cleaning device for a wind turbine generator set. Background Art

[0002] As the capacity of wind turbines increases, the weight of the blades and nacelles of wind turbines also increases. Ordinary electrical transmission can no longer meet the transmission requirements of wind turbines. Therefore, the wind power industry gradually replaces part of the electrical transmission with hydraulic transmission, making full use of the characteristics of the hydraulic system such as large output torque, fast response, and high control accuracy, making it an inevitable development trend in the application of large-capacity wind turbines. Due to the long operation time of wind turbines and external factors, oil and dust will inevitably adhere to the outer wall of the tower, showing black spots. If they are not cleaned in time for a long time, the paint on the outer wall of the tower will be eroded, and even worse, the iron wall will be corroded, causing the tower to collapse.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0056] like Figures 1 to 7 As shown, the present invention provides a wind turbine tower cleaning device, which includes a collar mechanism 1, a climbing mechanism 2, a brushing mechanism 3 and a driving mechanism 4. The collar mechanism 1 is sleeved on the outer periphery of the tower, the climbing mechanism 2 is connected to the upper end of the collar mechanism 1, the brushing mechanism 3 is connected to the inner wall of the collar mechanism 1, and the driving mechanism 4 is connected to the outer peripheral surface of the collar mechanism 1, and the driving mechanism 4 is meshed with the brushing mechanism 3.

[0057] During the use of the technical solution of the present invention, the brushing mechanism 3 can automatically brush the outer peripheral surface of the tower through the drive mechanism 4. During the brushing process, the climbing mechanism 2 can drive the device as a whole to move up and down on the outer wall of the tower, thereby realizing comprehensive automatic brushing of the tower. In actual operation, the operator only needs to install the sleeve mechanism 1 in the cleaning device on the outer peripheral surface of the tower, which can greatly reduce the labor burden and safety hazards of the operator. In addition, when the device flushes water on the surface of the tower, the brushing mechanism 3 can also drive the drive mechanism 4 to generate electricity, which can reduce energy loss and save costs.

[0058] like Figure 1 and Figure 2 As shown, the scrubbing mechanism 3 further includes a plurality of water pipes 5, which are connected to the outer peripheral surface of the collar mechanism 1, and the lower ends of the water pipes 5 are connected to nozzles 51, which correspond to the lower ends of the scrubbing mechanism 3. Specifically, in this embodiment, the nozzles 51 are high-pressure nozzles.

[0059] Specifically, in the present embodiment, the upper end of the collar mechanism 1 is fixedly connected with the climbing mechanism 2, the inner wall of the collar mechanism 1 is rotatably connected with the brushing mechanism 3, the outer peripheral surface of the collar mechanism 1 is fixedly connected with the driving mechanism 4, the driving mechanism 4 is meshed with the brushing mechanism 3, and the outer peripheral surface of the collar mechanism 1 is also fixedly connected with three water pipes 5 distributed in a ring shape, and the lower ends of the three water pipes 5 are fixedly connected with high-pressure nozzles, which correspond to the lower end of the brushing mechanism 3.

[0060] The collar mechanism 1 includes a first half-ring clamp 11, a second half-ring clamp 12, a first half-ring limit strip 13, and a second half-ring limit strip 14. The first half-ring clamp 11 and the second half-ring clamp 12 are fixed by bolts, and the first half-ring limit strip 13 and the second half-ring limit strip 14 are fixedly connected to the inner walls of the first half-ring clamp 11 and the second half-ring clamp 12, and the second half-ring limit strip 14 is located below the first half-ring limit strip 13. The outer peripheral surface of the scrubbing mechanism 3 is clamped between the first half-ring limit strip 13 and the second half-ring limit strip 14.

[0061] Specifically, in this embodiment, all components of the wind turbine tower cleaning device are evenly installed on the first half-ring clamp and the second half-ring clamp 12. The first half-ring clamp 11 and the second half-ring clamp 12 divide the cleaning device into two large components, which is convenient for the operator to install it on the outer circumferential surface of the tower.

[0062] like Figure 1 and Figure 2As shown, the climbing mechanism 2 includes a base 21, a clamping arm 22, a first servo motor 23, a mounting frame 24, a climbing roller 25 and a second servo motor 26. A plurality of bases 21 are connected to the upper end of the collar mechanism 1, and the plurality of bases 21 are distributed in a ring shape. The clamping arm 22 is connected to the upper end of the base 21, and the first servo motor 23 is connected to the upper end of the base 21 to control the rotation of the clamping arm 22. The mounting frame 24 is connected to the upper end of the clamping arm 22, and the climbing roller 25 is connected to the mounting frame 24. The second servo motor 26 is connected to one side of the mounting frame 24 to control the rotation of the climbing roller 25.

[0063] Specifically, in this embodiment, three ring-shaped distributed bases 21 are fixedly connected to the upper end of the ring mechanism 1 , and the upper ends of the three bases 21 are rotatably connected to the clamping arms 22 .

[0064] During the use of the cleaning device, the first servo motor 23 is started, and the first servo motor 23 will drive the clamping arm 22 to rotate. The three synchronously rotating clamping arms 22 can be tightly clamped on the outer circumferential surface of the tower, so that the cleaning device as a whole can remain stable at a high place. Then the second servo motor 26 is started. In the process of the second servo motor 26 driving the climbing roller 25 to rotate, the cleaning device as a whole can move up and down along the outer wall of the tower. The cleaning device as a whole can automatically move up and down on the outer wall of the tower, and the brush 37 can automatically brush the outer circumferential surface of the tower, thereby realizing comprehensive and automatic cleaning of the tower. Even at a high place, the cleaning device can clean it, which greatly reduces the safety hazards of operators during cleaning operations.

[0065] The outer peripheral surface of the climbing roller 25 is provided with an anti-slip rubber layer 251. By providing the anti-slip rubber layer 251, the friction between the climbing roller 25 and the outer wall of the tower can be greatly improved, so that the climbing roller 25 is not prone to slipping during climbing, thereby improving the overall stability of the cleaning device during the climbing process.

[0066] The scrubbing mechanism 3 includes a first connecting half ring 31, a second connecting half ring 32, a semi-toothed ring 33, a linkage blade 34, a telescopic rod 35, a connecting block 36 and a brush 37. The outer circumferences of the first connecting half ring 31 and the second connecting half ring 32 are fixedly connected with the semi-toothed ring 33, the semi-toothed ring 33 is clamped between the first half ring limit strip 13 and the second half ring limit strip 14, the semi-toothed ring 33 is meshed with the driving mechanism 4, the lower ends of the first connecting half ring 31 and the second connecting half ring 32 are connected with the linkage blade 34, the linkage blade 34 corresponds to the nozzle 51, the inner walls of the first connecting half ring 31 and the second connecting half ring 32 are connected with a plurality of telescopic rods 35 distributed in an annular shape, one end of the telescopic rod 35 is connected with the connecting block 36, and one side of the connecting block 36 is connected with the brush 37.

[0067] During the use of the cleaning device, the water pipe 5 is first connected to the external high-pressure water outlet hose, and water is sprayed out through the high-pressure nozzle to wet the surface of the tower. Then the permanent magnet synchronous motor 42 is started, and the permanent magnet synchronous motor 42 will drive the gear 43 to rotate. The rotating gear 43 can drive a pair of mutually docked semi-toothed rings 33 to rotate, and the rear semi-toothed ring 33 will synchronously drive the first connecting semi-ring 31 and the second connecting semi-ring 32 that are docked to rotate. Furthermore, the rotating first connecting semi-ring 31 and the second connecting semi-ring 32 cooperate with the telescopic rod 35 to drive the brush 37 to automatically scrub the surface of the tower, which can greatly reduce the labor burden of the operator. Among them, the brush 37 is adjusted by the telescopic rod 35 so that the brush 37 can contact the surface of the tower, and can also meet the cleaning needs of towers of different diameters.

[0068] like Figure 5 As shown, the scrubbing mechanism 3 also includes a battery pack 38 and a protective cover 39. Both the battery pack 38 and the protective cover 39 are connected to the inside of the first connecting half ring 31. The protective cover 39 is sleeved on the outside of the battery pack 38. The battery pack 38 and the telescopic rod 35 are electrically connected.

[0069] During the use of the cleaning device, since the telescopic rod 35 needs to rotate along with the first connecting half ring 31 and the second connecting half ring 32, in order to prevent the line from being entangled, the telescopic rod 35 is powered by the battery pack 38, and the battery pack 38 can rotate synchronously with the first connecting half ring 31. The battery pack 38 is protected by the protective cover 39, thereby reducing the possibility of the battery pack 38 being corroded by water stains and increasing the service life of the battery pack 38.

[0070] like Figure 5 and Figure 6 As shown, the scrubbing mechanism 3 further includes an electrode socket 311 and an electrode plug 321 . The electrode socket 311 is arranged at one end of the first connecting half ring 31 , and the electrode plug 321 is arranged at one end of the second connecting half ring 32 . The electrode socket 311 and the electrode plug 321 match each other.

[0071] During the use of the cleaning device, since the battery pack 38 is installed on the first connecting half ring 31, in order to be able to power the telescopic rod 35 on the second connecting half ring 32, when the first connecting half ring 31 and the second connecting half ring 32 are spliced, the electrode plug 321 will be embedded in the electrode socket 311.

[0072] like Figure 6 and Figure 7As shown, the collar mechanism 1 further includes a first small steel ball 141 and a second small steel ball 142. The first small steel ball 141 is movably connected to the side where the first half ring limit strip 13 and the second half ring limit strip 14 are close to each other, and the first small steel ball 141 contacts the upper and lower sides of the semi-toothed ring 33. The second small steel ball 142 is movably connected to the side where the first half ring limit strip 13 and the second half ring limit strip 14 are close to the first connecting half ring 31 and the second connecting half ring 32, and the second small steel ball 142 contacts the first connecting half ring 31 and the second connecting half ring 32.

[0073] During the use of the cleaning device, the first half ring limiting strip 13 and the second half ring limiting strip 14 can limit the half toothed ring 33, thereby improving the stability of the half toothed ring 33 during the rotation process. Moreover, the first half ring limiting strip 13 and the second half ring limiting strip 14 are in contact with the half toothed ring 33 through the first small steel ball 141 and the second small steel ball 142, which can greatly reduce the friction resistance of the half toothed ring 33 during the rotation process, thereby reducing energy consumption and parts wear.

[0074] like Figure 7 As shown, the driving mechanism 4 includes a connecting member 41, a permanent magnet synchronous motor 42 and a gear 43. The permanent magnet synchronous motor 42 is fixedly connected to the lower end of the connecting member 41, and the gear 43 is fixedly connected to the output shaft of the permanent magnet synchronous motor 42. The gear 43 is meshed with the half gear ring 33.

[0075] In the use of the cleaning device, there is no essential difference between the drive motor and the generator, the physical structure is basically the same, and both are reversible. The drive motor drives the rotor to operate by mutual repulsion of the magnetic field formed by the current. The permanent magnet synchronous motor 42 in the present invention forms a magnetic field in the winding, and the permanent magnet repel each other to make the rotor operate, and the rotor is then driven. The generator is driven to operate under the action of external mechanical energy. During the rotation process, the current is generated by cutting the magnetic lines of force, and the coil generates an induced electromotive force in the rotating magnetic field, and the rotor coil can generate electricity.

[0076] In the process of the high-pressure nozzle spraying water to the tower surface, the permanent magnet synchronous motor 42 is in a stopped state, and its high-pressure water column will first impact the linkage blade 34. The linkage blade 34 cooperates with the first connecting half ring 31 and the second connecting half ring 32 to drive the half gear ring 33 to rotate. The rotating half gear ring 33 will drive the gear 43 to rotate at high speed. The high-speed rotating gear 43 will provide external mechanical energy for the permanent magnet synchronous motor 42, so that the permanent magnet synchronous motor 42 generates electricity. After the generated electricity is stored in the energy storage device, it can be used by the permanent magnet synchronous motor 42 and the first servo motor 23 and the second servo motor 26, which can reduce energy loss and save costs. Among them, the energy storage device is installed on the working vehicle and is connected to the permanent magnet synchronous motor 42 and the first servo motor 23 and the second servo motor 26 through cables, which is not shown in the figure.

[0077] Working process:

[0078] When the operator uses the device, he first connects the water pipe 5 to the external high-pressure water outlet hose, and sprays water through the high-pressure nozzle to wet the surface of the tower. Then, the first servo motor 23 is started, and the first servo motor 23 will drive the clamping arm 22 to rotate. The three synchronously rotating clamping arms 22 can be tightly clamped on the outer circumferential surface of the tower, so that the cleaning device as a whole can remain stable at a high place. Then, the second servo motor 26 is started. In the process of the second servo motor 26 driving the climbing roller 25 to rotate, the cleaning device as a whole can move up and down along the outer wall of the tower. Then, the permanent magnet synchronous motor 42 is started, and the permanent magnet synchronous motor 42 will drive the gear 43 to rotate. The rotating gear 43 can drive a pair of mutually connected half-toothed rings 33 to rotate, and the rear half-toothed ring 33 will synchronously drive the first connecting half ring 31 and the second connecting half ring 32 to rotate. Furthermore, the rotating first connecting half ring 31 and the second connecting half ring 32 cooperate with the telescopic rod 35 to drive the brush 37 to automatically scrub the surface of the tower, which can greatly reduce the labor burden and safety hazards of personnel. The brush 37 can be adjusted by the telescopic rod 35 so that the brush 37 can contact the surface of the tower, which can meet the cleaning needs of towers with different diameters.

[0079] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
