Description

Technical Field

[0001] The invention belongs to the technical field of wind power tower cleaning, and particularly relates to an oil stain cleaning device for a wind power tower. Background Art

[0002] The wind power tower is the tower pole of wind power generation, which mainly plays a supporting role in the wind power generating unit and absorbs the vibration of the unit at the same time. During the use of the gearbox of the wind power generating unit, wear will occur, resulting in the leakage of lubricating oil. This leaked lubricating oil will flow to the outer surface of the wind power tower and form oil stains. For the cylindrical wind power tower with a large bottom diameter and a small top diameter, its outer wall is an inclined curved surface structure. The existing oil stain cleaning devices are not convenient for climbing on the outer wall of the wind power tower, which is not conducive to the cleaning device to clean the outer wall of the wind power tower.

The peripheral terminal receives the signal and controls the pump body 508 at the top end of this liquid storage box 504 to close, and another pump body 508 to open, so that the cleaning agent in another group of liquid storage boxes 504 is put into use. At the same time, the solenoid valve 506 connected to this liquid storage box 504 is opened, and the cleaning agent is replenished through the liquid replenishing pipe fitting 505;

[0044] Reference Figures 1-3 , Figure 5 and Figure 6As shown, the cleaning mechanism 50 further includes a secondary split gear ring 512, a sleeve 513, a return spring 514, a push rod 515 and a circular plate 516. The secondary split gear ring 512 is arranged at the top of the hollow half ring 501. The sleeves 513 are circumferentially arrayed and connected to the inner wall of the secondary split gear ring 512.

[0045] The side of the scraping plate 503 opposite to the push rod 515 is provided with an inclined surface structure.

[0046] Reference Figure 1 、 Figure 3 and Figure 5 As shown in

[0047] The top of the secondary split gear ring 512 is provided with an anti-disengagement notch 521. An anti-disengagement round rod 522 is slidably matched in the anti-disengagement notch 521, and the top of the anti-disengagement round rod 522 is connected to the limiting member 517 to limit the secondary split gear ring 512, so that the secondary split gear ring 512 can rotate stably.

[0048] When the present invention is in use, two sets of positioning semi - rings 10 are sleeved on the bottom end of the outer wall of the wind power tower barrel, and two sets of liquid storage boxes 504 are accordingly located on the outer wall of the wind power tower barrel. Two sets of first - level fixing plates 101 are used to connect and fix the two sets of positioning semi - rings 10, and two sets of second - level fixing plates 5041 are used to connect and fix the two sets of liquid storage boxes 504. Two sets of first - level half - toothed rings 407 are arranged between the top of the positioning semi - rings 10 and the limiting frame 408, and two sets of third - level fixing plates 4071 are used to connect and fix the two sets of first - level half - toothed rings 407;

[0049] The first - level driving motor 412 is started, so that the first - level gear 413 rotates, thereby causing the two sets of first - level half - toothed rings 407 to rotate around the center, driving the rotating plate member 409 to rotate, and causing the circular rod member 406 to slide in the sliding notch 410, thereby pulling the telescopic rod 401 out of the external square tube 404 until the rolling wheel 30 contacts the wind power tower barrel. The wind power tower barrel forms a resistance to the rolling wheel 30, and this resistance is transmitted to the pressure sensor 402 through the rolling wheel 30, the double - shaft motor 20, and the mounting plate member 403. The pressure sensor 402 senses this resistance. When the resistance reaches the preset value of the pressure sensor 402, it indicates that this resistance, that is, the pressing force of the rolling wheel 30 on the wind power tower barrel, meets the standard. Under the action of the friction force between the rolling wheel 30 and the outer wall of the wind power tower barrel, the device will not drop due to the action of gravity. The double - shaft motor 20 is started to make the rolling wheel 30 rotate, driving the device to rise. Since the diameter of the upper end of the wind power tower barrel is smaller than that of the lower end, when the device rises, because the rolling wheel 30 cannot fully fit the wind power tower barrel, the pressing force of the rolling wheel 30 on the wind power tower barrel decreases, and the pressure sensed by the pressure sensor 402 is lower than the preset value. The pressure sensor 402 transmits the data to the external device terminal, and the external device terminal receives the data and controls the first - level driving motor 412 to start, thereby making the telescopic rod 401 extend further, reducing the diameter of the circle formed by all the rolling wheels 30 together, making the rolling wheel 30 fit and press the wind power tower barrel more fully, increasing the pressing force of the rolling wheel 30 on the wind power tower barrel, and making the value of the pressure sensor 402 reach the preset value again. At the same time, the rolling wheel 30 continues to rotate until the top of the device contacts the equipment at the top of the wind power tower barrel and cannot continue to rise. At this time, the double - shaft motor 20 cannot continue to rotate. At this time, the external device terminal receives the signal that the double - shaft motor 20 cannot continue to rotate, controls the double - shaft motor 20, and closes the double - shaft motor 20 and the first - level driving motor 412, thereby completing the climbing of the device;

[0050] Before cleaning, the device first climbs to the highest point and is cleaned from high to low. When cleaning, the pump body 508 is turned on, and the cleaning agent in the liquid storage box 504 is sprayed onto the outer wall of the wind power tower through the primary conduit 509, secondary conduit 510, hollow semi-ring 501, and nozzle 502 for pre-treatment of the oil stain. After the pre-treatment is completed, the secondary drive motor 519 is turned on to rotate the secondary gear 518, thereby driving the two sets of secondary half-tooth rings 512 to rotate, causing the scraper 503 to rotate. Under the action of the return spring 514, the scraper 503 will press tightly against the wind power tower, thereby scraping off the pre-treated oil stain at this height. Since there are multiple scrapers 503, the oil stain on the outer wall of the wind power tower can be removed in a short time;

[0051] By making the device descend periodically, the outer wall of the wind power tower is sequentially divided into multiple regions from top to bottom. When the device needs to descend, compared with making the device ascend, the biaxial motor 20 is turned on to make the rolling wheels 30 rotate in the reverse direction. Similarly, since the diameter of the lower end of the wind power tower is larger than that of the upper end, under the action of friction, if the rolling wheels 30 continue to rotate, the friction force will increase, and there will be a lateral force in the friction force. This force is transmitted to the pressure sensor 402 through the rolling wheels 30, biaxial motor 20, and mounting plate member 403. At this time, the force value monitored by the pressure sensor 402 will become larger, that is, greater than the preset value. The pressure sensor 402 transmits the data to the peripheral terminal, and the peripheral terminal receives the data and controls the primary drive motor 412 to turn on, thereby making the primary gear 413 and primary half-tooth ring 407 rotate in the reverse direction, causing the telescopic rod 401 to contract, increasing the diameter of the circle formed by all the rolling wheels 30 together, thereby being able to reduce the extrusion force of the rolling wheels 30 on the wind power tower, making the value monitored by the pressure sensor 402 decrease and again be at the preset value. At the same time, the rolling wheels 30 continue to rotate until the rolling wheels 30 rotate to the preset number of turns. At this time, the peripheral terminal receives the signal that the biaxial motor 20 has completed rotation and controls the biaxial motor 20 and the primary drive motor 412 to turn off, thereby completing the descent of the device;

[0052] For the descending height of the device, the number of rotations of the output shaft of the biaxial motor 20 is pre-controlled according to the outer circumference length of the rolling wheels 30, thereby realizing the segmented descent of the device and achieving regional division.

[0053] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
