In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0036] Example 1, reference Figures 1 to 13 , which is the first embodiment of the present invention, provides a wind turbine bearing cleaner, the device comprising a bearing mechanism 100, including a wind turbine shaft 101 and a bearing mounting shell 103, a wind turbine bearing 102 disposed between the wind turbine shaft 101 and the bearing mounting shell 103;

[0037] The cleaning mechanism 200 includes a mounting portion 201 disposed on the wind turbine shaft 101, an upper cleaning portion 202 disposed on the mounting portion 201, an upper extraction portion 203 disposed on the upper cleaning portion 202, a lower cleaning portion 204 disposed on the mounting portion 201, a lower extraction portion 205 disposed on the lower cleaning portion 204, a connecting portion 206 disposed on the mounting portion 201, a collecting portion 207 disposed on the mounting portion 201, an aligning portion 208 disposed on the mounting portion 201, and a spacing portion 209 disposed on the mounting portion 201.

[0038] During use, the mounting portion 201 is placed on the wind power generation shaft 101, and the spacing portion 209 is in close contact with the side of the wind power generation bearing 102, ensuring that the upper cleaning portion 202 and the lower cleaning portion 204 can be inserted into the wind power generation bearing 102 at an angle. After the upper cleaning portion 202 is started and the upper cleaning portion 202 and the lower cleaning portion 204 are inserted into the wind power generation bearing 102, the mounting portion 201 is completely fixed on the wind power generation shaft 101, thereby ensuring that the gaps that need to be cleaned in the wind power generation bearing 102 correspond to the alignment portion 208 one by one. When the upper cleaning portion 202 and the lower cleaning portion 204 are inserted into the wind power generation bearing 102, the upper cleaning portion 201 is 202 and the lower cleaning part 204 clean the surface of the wind power generation bearing 102, and at the same time start the connecting part 206, so that the upper half of the grease in the gap of the wind power generation bearing 102 enters the collecting part 207 through the upper extraction part 203, the upper cleaning part 202, and the connecting part 206, and the lower half of the grease in the gap of the wind power generation bearing 102 enters the collecting part 207 through the lower extraction part 205, the lower cleaning part 204, and the connecting part 206, so that the grease in the gap is extracted, and the angle of the mounting part 201 is adjusted so that the mounting part 201 is fixed in the adjacent alignment part 208, so that the adjacent gap of the wind power generation bearing 102 can be cleaned.

[0039] Example 2, reference Figure 1 to Figure 4, which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: a wind power generation bearing 102 includes a bearing inner ring 102a arranged on a wind power generation shaft 101, a bearing outer ring 102c arranged on a bearing mounting shell 103, a cylindrical roller 102b arranged between the bearing inner ring 102a and the bearing outer ring 102c, the cylindrical roller 102b is inclined, a roller frame 102d arranged on the cylindrical roller 102b, a lower cleaning chamber 102e arranged between the roller frame 102d and the bearing inner ring 102a, and an upper cleaning chamber 102f arranged between the roller frame 102d and the bearing outer ring 102c.

[0040] Furthermore, the bearing inner ring 102a is fixedly arranged on the wind turbine shaft 101, and a plurality of cylindrical rollers 102b are arranged and tilted. The tilting of the cylindrical rollers 102b can improve the lubrication conditions in the bearing. The upper cleaning cavity 102f is sleeved on the cylindrical rollers 102b and is used to limit the cylindrical rollers 102b so that the cylindrical rollers 102b are distributed in a circular array. The lower cleaning cavity 102e is a gap formed between the bearing inner ring 102a, the cylindrical rollers 102b, and the roller frame 102d. The upper cleaning cavity 102f is a gap formed between the cylindrical rollers 102b, the bearing outer ring 102c, and the roller frame 102d.

[0041] The remaining structures are the same as those of Example 1.

[0042] Example 3, reference Figure 5 to Figure 13 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the mounting portion 201 includes a mounting ring 201a arranged on the wind power generation shaft 101, a mounting groove 201b arranged on the mounting ring 201a, a mounting slider 201c arranged in the mounting groove 201b, and a mounting plate 201d arranged on the mounting slider 201c.

[0043] Furthermore, the mounting ring 201a is composed of two half rings, which can be fixed by bolts to form a circular ring. The mounting groove 201b is arranged in a ring so that the mounting slider 201c can circle around. The mounting slider 201c is slidably arranged in the mounting groove 201b, and the mounting plate 201d is fixed on the mounting slider 201c by bolts.

[0044] The upper cleaning portion 202 includes a threaded tube 202a disposed on a mounting plate 201d, the threaded tube 202a being inclined, a threaded sleeve 202b disposed on the threaded tube 202a, an upper cleaning plate 202c disposed on the threaded sleeve 202b, a motor 202d disposed on the mounting plate 201d, an output gear 202e disposed on the motor 202d, and an input gear 202f disposed on the threaded tube 202a and matched with the output gear 202e.

[0045] Furthermore, the threaded tube 202a is rotatably set on the mounting plate 201d, the threaded tube 202a is tilted, and the inclination of the threaded tube 202a is the same as the inclination of the cylindrical roller 102b. Therefore, by confirming the distance between the upper cleaning plate 202c and the cylindrical roller 102b, the upper cleaning plate 202c can be moved along the threaded tube 202a into the upper cleaning chamber 102f to ensure the normal use of the device. The threaded sleeve 202b is threadedly connected to the threaded tube 202a, and the threaded sleeve 202b is fixedly connected to the upper cleaning plate 202c. The upper cleaning plate 202c is adapted to the upper cleaning chamber 102f to ensure that the upper cleaning plate 202c can enter the upper cleaning chamber 102f.

[0046] Furthermore, the motor 202d is fixed on the mounting plate 201d, the output gear 202e is fixed on the output end of the motor 202d, the input gear 202f is sleeved and fixed on the threaded tube 202a, and the motor 202d, the output gear 202e, and the input gear 202f are tilted as a whole to ensure the normal rotation of the threaded tube 202a. Starting the motor 202d drives the output gear 202e to rotate the input gear 202f, and the input gear 202f drives the threaded tube 202a to move the threaded sleeve 202b along the threaded tube 202a to ensure the normal operation of the device.

[0047] The upper extraction part 203 includes an upper extraction main hole 203a arranged on the upper cleaning plate 202c and adapted to the threaded tube 202a, an upper extraction branch hole 203b arranged on the upper cleaning plate 202c and connected to the upper extraction main hole 203a, and an upper cleaning arc surface 203c arranged on the upper cleaning plate 202c and adapted to the cylindrical roller 102b.

[0048] Furthermore, the opening of the upper extraction main hole 203a not only provides space for the threaded tube 202a to expand and contract, but also provides a cavity for extracting grease. The upper extraction branch holes 203b are opened on both sides of the upper cleaning plate 202c, so that the grease scraped off the upper cleaning arc surface 203c can be extracted through the upper extraction branch holes 203b, thereby ensuring the cleaning effect of the device. The upper cleaning arc surface 203c is compatible with the cylindrical roller 102b, so that the surface of the cylindrical roller 102b can be cleaned.

[0049] The lower cleaning part 204 includes a lower cleaning tube 204a arranged on the mounting plate 201d, the lower cleaning tube 204a is arranged at an angle, a lower cleaning sleeve 204b arranged on the lower cleaning tube 204a, a lower cleaning plate 204c arranged on the lower cleaning sleeve 204b, and a lower connecting rod 204d arranged on the lower cleaning sleeve 204b and connected to the threaded sleeve 202b.

[0050] Furthermore, the lower cleaning tube 204a is fixedly arranged on the mounting plate 201d to increase the stability of the device. The inclination of the lower cleaning tube 204a is the same as that of the threaded tube 202a. The lower cleaning sleeve 204b is slidably arranged on the lower cleaning tube 204a and is fixedly connected to the threaded sleeve 202b through the lower connecting rod 204d. Therefore, the upper cleaning plate 202c drives the threaded sleeve 202b to move, and the threaded sleeve 202b drives the lower cleaning sleeve 204b to move along the lower cleaning tube 204a. The lower cleaning sleeve 204b is fixedly connected to the lower cleaning plate 204c. Therefore, the movement of the upper cleaning plate 202c can drive the lower cleaning plate 204c to move, so that the upper cleaning plate 202c and the lower cleaning plate 204c move synchronously to clean the surface of the cylindrical roller 102b, and can be synchronously inserted into the upper cleaning cavity 102f and the lower cleaning cavity 102e respectively to complete the extraction of grease.

[0051] The lower extraction part 205 includes a lower extraction main hole 205a arranged on the lower cleaning plate 204c and adapted to the lower cleaning tube 204a, a lower extraction branch hole 205b arranged on the lower cleaning plate 204c and connected to the lower extraction main hole 205a, and a lower cleaning arc surface 205c arranged on the lower cleaning plate 204c and adapted to the cylindrical roller 102b.

[0052] Furthermore, the lower extraction main hole 205a provides space for the lower cleaning tube 204a to shrink, and the lower cleaning tube 204a blocks the lower extraction branch hole 205b, so that the grease is first extracted through the lower extraction main hole 205a, and as the lower cleaning plate 204c enters, the scraped grease is extracted through the lower extraction branch hole 205b. The setting of the lower cleaning arc surface 205c enables the lower cleaning plate 204c to clean the surface of the cylindrical roller 102b when it moves.

[0053] The connecting portion 206 includes an oil pump 206a disposed on the mounting plate 201d, a first connecting pipe 206b disposed on the oil pump 206a, a second connecting pipe 206c disposed on the first connecting pipe 206b and connected to the lower cleaning pipe 204a, a first branch pipe 206d disposed on the second connecting pipe 206c, a second branch pipe 206e disposed on the first branch pipe 206d, and a sealed bearing 206f disposed on the second branch pipe 206e and connected to the threaded pipe 202a.

[0054] Furthermore, the oil pump 206a is fixedly arranged on the mounting plate 201d, one end of the first connecting pipe 206b is communicated with the input end of the oil pump 206a, one end of the second connecting pipe 206c is communicated with the first connecting pipe 206b, and the other end is communicated with the lower cleaning pipe 204a, so that the oil pump 206a can extract grease through the lower cleaning pipe 204a, one end of the first branch pipe 206d is communicated with the surface of the second connecting pipe 206c, the surface of the second branch pipe 206e is communicated with the other end of the first branch pipe 206d, one end of the second branch pipe 206e is communicated with the sealed bearing 206f, the sealed bearing 206f is communicated with the threaded pipe 202a, and the threaded pipe 202a is rotatably connected to the sealed bearing 206f, which not only ensures the normal rotation and use of the threaded pipe 202a, but also ensures that the oil pump 206a can extract grease through the threaded pipe 202a, thereby ensuring the normal use of the device.

[0055] The collecting portion 207 includes a collecting annular groove 207a provided on the mounting ring 201a, a collecting slider 207b provided on the collecting annular groove 207a, a collecting box 207c provided on the collecting slider 207b, and a collecting pipe 207d provided on the collecting box 207c and connected to the oil pump 206a.

[0056] Furthermore, the collecting annular groove 207a is opened on the mounting ring 201a and is arranged in an annular shape, so that the collecting slider 207b can move along the collecting annular groove 207a, and the collecting box 207c is fixedly set on the collecting slider 207b. The setting of the collecting pipe 207d allows the grease extracted by the oil pump 206a to be discharged into the collecting pipe 207d for collection, and when the oil pump 206a adjusts its angle, it can drive the collecting box 207c to move along, and there is no need to set a longer hose, which facilitates the use of the device.

[0057] The alignment portion 208 includes an alignment telescopic groove 208a arranged on the mounting slider 201c, an alignment spring 208b arranged in the alignment telescopic groove 208a, an alignment boss 208c arranged on the alignment spring 208b, an alignment groove 208d arranged in the mounting groove 201b and matched with the alignment boss 208c, and an alignment locking groove 208e arranged in the alignment groove 208d. The alignment locking grooves 208e are in a ring array, and the number of the alignment locking grooves 208e is the same as the number of the cylindrical rollers 102b.

[0058] Furthermore, the alignment telescopic groove 208a is used to install the alignment spring 208b and provide space for the alignment boss 208c to expand and contract. The alignment spring 208b provides power for the alignment boss 208c to reset. The end of the alignment boss 208c is hemispherical in design. The alignment slide groove 208d provides space for the movement of the alignment boss 208c. There are several alignment locking grooves 208e, and the number is the same as the cylindrical roller 102b, and they are distributed in a ring array. Therefore, one alignment locking groove 208e corresponds to one upper cleaning cavity 102f, which can ensure that the remaining alignment locking grooves 208e correspond to the remaining upper cleaning cavities 102f one by one, and there is no need to perform alignment operations on each gap, thereby facilitating the insertion operation of the upper cleaning plate 202c and the lower cleaning plate 204c.

[0059] The distance portion 209 includes a distance rod 209a disposed on the mounting plate 201d and a distance wheel 209b disposed on the distance rod 209a.

[0060] Furthermore, the distance rod 209a is fixedly set on the mounting plate 201d, and the distance wheel 209b is a universal wheel, which reduces the friction when the distance rod 209a moves, and facilitates the angle adjustment of the device. At the same time, the setting of the distance rod 209a ensures the distance between the mounting plate 201d and the inner ring of the bearing 102a, thereby ensuring that the upper cleaning plate 202c and the lower cleaning plate 204c can be just inserted into the lower cleaning cavity 102e and the upper cleaning cavity 102f when moving, ensuring the normal use of the device.

[0061] The remaining structure is the same as that of Example 2.

[0062] During use, the mounting ring 201a is placed on the wind power generation shaft 101 and initially fixed with bolts. The mounting ring 201a is moved along the wind power generation shaft 101 so that the distance wheel 209b on the distance rod 209a is in close contact with the side of the bearing inner ring 102a to ensure the distance between the mounting ring 201a and the wind power generation bearing 102, thereby ensuring the normal use of the device. The motor 202d is started to drive the output gear 202e to rotate the input gear 202f, and the input gear 202f drives the threaded tube 202a to rotate. Due to the limitation of the threaded sleeve 202b by the lower connecting rod 204d, the threaded sleeve 202b is moved by the rotation of the threaded tube 202a, and the threaded sleeve 202b drives the upper cleaning The plate 202c moves, and at the same time, the threaded sleeve 202b drives the lower connecting rod 204d to move the lower cleaning sleeve 204b, and the lower cleaning sleeve 204b drives the lower cleaning plate 204c to move. Since the inclination of the threaded tube 202a and the lower cleaning tube 204a is the same as that of the cylindrical roller 102b, and the inclined insertion distance of the upper cleaning plate 202c and the lower cleaning plate 204c is guaranteed, the upper cleaning plate 202c can be just inserted into the upper cleaning cavity 102f, and the lower cleaning plate 204c can be just inserted into the lower cleaning cavity 102e. Due to the setting of the upper cleaning arc surface 203c and the lower cleaning arc surface 205c, the upper cleaning plate 202c and the lower cleaning plate 204c can clean the surface of the cylindrical roller 102b;

[0063] When the upper cleaning plate 202c and the lower cleaning plate 204c are inserted for the first time, the mounting ring 201a is completely fixed to ensure that the alignment locking groove 208e corresponds to the gap between the cylindrical roller 102b. The mounting plate 201d is fixed on the corresponding alignment locking groove 208e to complete the alignment of the upper cleaning plate 202c, the lower cleaning plate 204c and the upper cleaning cavity 102f and the lower cleaning cavity 102e, so that the device does not need to perform alignment operations when cleaning adjacent gaps.

[0064] When the upper cleaning plate 202c and the lower cleaning plate 204c are inserted into the upper cleaning chamber 102f and the lower cleaning chamber 102e, the upper cleaning plate 202c and the lower cleaning plate 204c clean the surface of the upper cleaning chamber 102f and the lower cleaning chamber 102e, and at the same time, the oil pump 206a is started, and the oil pump 206a removes the grease in the upper cleaning chamber 102f through the upper extraction branch hole 203b, the upper extraction main hole 203a, the threaded pipe 202a, the sealed bearing 206f, the second The branch pipe 206e, the first branch pipe 206d, the second connecting pipe 206c, and the first connecting pipe 206b are extracted, and the oil pump 206a extracts the grease in the lower cleaning chamber 102e through the lower extraction branch hole 205b, the lower extraction main hole 205a, the lower cleaning pipe 204a, the second connecting pipe 206c, and the first connecting pipe 206b. The oil pump 206a discharges the extracted grease into the collection box 207c through the collection pipe 207d, thereby collecting the grease;

[0065] When it is necessary to clean the adjacent upper cleaning chamber 102f and lower cleaning chamber 102e, the movable mounting plate 201d drives the mounting slider 201c to move the alignment boss 208c, and the alignment locking groove 208e squeezes the alignment boss 208c to shrink the alignment boss 208c into the alignment telescopic groove 208a. When the alignment boss 208c coincides with the adjacent alignment locking groove 208e, the elastic force of the alignment spring 208b drives the alignment boss 208c to be inserted into the alignment locking groove 208e, thereby completing the fixation of the mounting plate 201d and simultaneously completing the alignment of the upper cleaning plate 202c, the lower cleaning plate 204c with the upper cleaning chamber 102f and the lower cleaning chamber 102e. After completing the above cycle, cleaning can be carried out.
