Description

Technical Field

[0001] The invention relates to the technical field of wind power generation, in particular to a split type multi-safety wind power generation fan blade cleaning device. Background Art

[0002] Wind power generation is a clean, pollution-free, renewable energy source, mainly used in wilderness areas. Previously, it was mainly used in western my country. With the development of science and technology in my country, it can be seen everywhere in mountains, plains and fields. With the vigorous development of wind power generation, the workload of cleaning and maintenance of fan blades has also increased.

[0003] Since wind power generation is built in the wild and the working environment is relatively harsh, the fan blades need to be maintained regularly to ensure the normal operation of wind power generation. The fan blades are outdoors for a long time and are exposed to dust, debris, feces, dirt and other impurities that need to be cleaned regularly, otherwise it will cause malfunctions and affect the normal operation of wind power generation.

[0004] At present, fan blades are mostly cleaned manually at high altitude, such as but not limited to high altitude V-shaped working platforms, U-shaped working platforms, circular working platforms, straight-line working platforms, etc. This type of platform has many advantages, and is convenient for comprehensive maintenance such as cleaning, repair, inspection, and installation of fan blades. However, when cleaning the fan blades regularly, high-altitude operations pose a great risk to manual labor.

[0005] The patent library contains cleaning devices that do not require high-altitude manual labor when cleaning fan blades, but these devices have the following disadvantages:

[0006] Due to the irregularity of the fan blades, it is impossible to better adapt to the shape of the fan blades when cleaning the fan blades. Due to the large size of the fan blades, the size and weight of the cleaning device used will also be relatively large. During the reciprocating motion, the excessive weight will cause the cleaning device to fall, causing greater safety hazards. In addition, since the wind power tower is very high, once the cleaning device falls, it is likely to cause damage. If you are far away from the tower, you will not be able to observe the cleaning condition closely.

[0007] On this basis, the present invention provides a split-type multi-safety wind power generation fan blade cleaning device to solve the technical problem. Summary of the invention

DETAILED DESCRIPTION

[0039] The above and other technical contents, features and effects of the present invention are described in detail below with reference to the attached Figures 1 to 8 The details of the embodiments will be clearly presented. The contents mentioned in the following embodiments are all based on the drawings in the specification.

[0040] Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings.

[0041] The present invention is a split-type multi-safety wind turbine blade cleaning device, which is mainly used for cleaning wind turbine blades during maintenance, and does not include installation, welding, repair, etc. The wind turbine structure mainly includes a tower, a ladder, rotating blades, an impeller drum, a gearbox, a brake device, a power generation device, a generator, etc.

[0042] The present invention is mainly used for cleaning rotating fan blades, and comprises a cleaning assembly 1 for cleaning the fan blades. When in use, the cleaning assembly 1 needs to be installed on the fan blades in advance.

[0043] In a specific embodiment, the cleaning assembly 1 includes a left frame 2 and a right frame 3, both of which have the same structure. An arc-shaped side scraper 4 is fixed to the left end of the left frame 2 and the right end of the right frame 3. A side cleaning cotton 51 is removably fixedly installed in the side scraper 4 for being stuck on both sides of the fan blades and used for cleaning the sides of the fan blades.

[0044] A cleaning belt 5 is installed between the left frame 2 and the right frame 3. The cleaning belt 5 is a flexible belt. The flexible belt passes horizontally from the upper end, bypasses the side scraper 4, and passes horizontally from the lower end. Cleaning rollers 6 are wrapped around both ends of the cleaning belt 5, and the ends of the cleaning rollers 6 are coaxially connected to a cleaning motor 7.

[0045] It should be noted that the cleaning roller 6 is fixed on the cleaning roller frame of the right frame 3, and the cleaning motor 7 is connected to a controller and a control switch.

[0046] Support plates 8 are fixed at the upper and lower ends of the left frame 2 and the right frame 3. Main rotating rods 9 symmetrical on both sides are rotatably installed on the support plates 8. Main pressure rollers 10 are rotatably installed at the ends of the main rotating rods 9. The main pressure rollers 10 are pressed on the cleaning belt 5 to make the cleaning belt 5 as close to the fan blades as possible. An active rod 11 is fixed on the main rotating rod 9. A main cylinder 12 is rotatably installed on the support plate 8. The other end of the main cylinder 12 is rotatably mounted on the active rod 11. A pressure sensor is installed on the main pressure roller 10. The main cylinder 12 is mainly used to adjust the pressing force of the main pressure roller 10.

[0047] In addition to the main rotating rod 9, a secondary rotating rod 13 is rotatably installed at the lower end portion of the main rotating rod 9, and a secondary pressure roller 14 is rotatably installed at the end of the secondary rotating rod 13. The secondary pressure roller 14 presses on the cleaning belt 5. A pressure sensor is also installed on the secondary pressure roller 14. A secondary moving rod 15 is fixed on the secondary rotating rod 13, and a secondary cylinder 16 is rotatably installed on the support plate 8. The other end of the secondary cylinder 16 is rotatably sleeved on the secondary moving rod 15.

[0048] A distance sensor 17 for opposite illumination is fixed on the upper end of the support plate 8 .

[0049] It should be noted that, since the fan blades are not absolutely regular, the main pressure roller 10 and the secondary pressure roller 14 do not make the cleaning belt 5 fit the fan blades perfectly, but try to improve the fit. The cleaning belt 5 and the fan blades do not need to fit perfectly, because the fan blades are in the wild for a long time and will be in a harsh environment. Therefore, even during cleaning and maintenance, it does not need to be absolutely clean, but only large and most impurities on the fan blades can be cleaned.

[0050] It should also be noted that the distance sensor 17 is connected to a controller for sensing the pressure of the cleaning belt 5 and then sending a signal to the main cylinder 12 and the secondary cylinder 16 for telescopic adjustment.

[0051] The distance sensor 17 is connected to the controller to detect the distance between the left frame 2 and the right frame 3, and then sends a signal to the cleaning motor 7 for winding and releasing.

[0052] A more detailed principle is that one of the fan blades is stopped at the lower vertical position, and the cleaning component 1 is mounted on the fan blade. The cleaning component 1 will reciprocate according to the subsequent driving component. Since the fan blades are irregular in size, the cleaning belts 5 at the upper and lower ends are attached to the fan blades when the cleaning component 1 is performing reciprocating cleaning. Since the cleaning belt 5 is a flexible belt, the main pressure roller 10 and the secondary pressure roller 14 are used to press the cleaning belt 5 against the fan blades. When the pressure value between the cleaning belt 5 and the main pressure roller 10 and the secondary pressure roller 14 changes within a certain range, a signal is sent to the controller, thereby controlling the main cylinder 12 and the secondary cylinder 16 to adjust the main pressure roller 10 and the secondary pressure roller 14. Here, the cleaning of the cleaning belt 5 is mainly performed on the upper and lower sides.

[0053] It should be noted that the two side surfaces of the fan blades are mainly cleaned by the side cleaning cotton 51 .

[0054] When cleaning the fan blades in the left and right directions, when the length of the fan blades in the left and right directions changes, it will automatically adapt through the expansion and contraction between the left frame 2 and the right frame 3. Although the cleaning belt 5 is flexible, its flexibility is not enough to adapt to the length change caused by the huge fan blades. Therefore, when the left frame 2 and the right frame 3 expand and contract, the distance sensor 17 detects the distance change and sends a signal to the cleaning motor 7, and the cleaning motor 7 winds and releases respectively to achieve adaptation in the length direction.

[0055] As an embodiment, the cleaning belt 5 is cleaned according to the degree of cleaning or one or more reciprocating settings. A scraping assembly 18 is installed on the cleaning belt 5 between the right frame 3 and the cleaning motor 7. The scraping assembly 18 includes a scraping frame 19 fixed on the right frame 3. The scraping frame 19 is a frame structure. A scraping comb 20 arranged up and down and a squeezing roller 21 installed for rolling up and down are fixed in the scraping frame 19. The cleaning belt 5 passes between the scraping comb 20 and the squeezing roller 21. The scraping comb 20 is used to scrape off the block and granular impurities on the cleaning belt 5. The squeezing roller 21 is used to squeeze the dirty water on the cleaning belt 5.

[0056] It should be noted that the scraping assembly 18 is fixed on the scraping assembly plate of the right frame 3 .

[0057] As an embodiment, the sliding connection between the left frame 2 and the right frame 3 is that a right slide 22 with four internal cavities symmetrically arranged in the upper and lower parts is fixed on the inner side of the right frame 3, an adjusting spring 24 is installed on the bottom of the right slide 22, and four left slide rods 23 symmetrically arranged in the upper and lower parts are fixed on the inner side of the left frame 2. The left slide rod 23 is slidingly connected in the right slide 22, and the adjusting spring 24 is sleeved on the left slide rod 23 to realize automatic telescopic adjustment of the left frame 2 and the right frame 3.

[0058] In addition to the cleaning belt 5, a soft brush 25 is fixed at the bottom of the left slide bar 23 and the right slide channel 22 for cleaning the fan blades. Firstly, the impurities and dust on the fan blades can be cleaned in advance, and secondly, the left slide bar 23 is not hindered or restricted by the brush 25 when it is extended and retracted in the right slide channel 22.

[0059] A slidably fitted limiting rod 26 is fixed to the inner side of the left slide bar 23 and the right slide rail 22. The limiting rods 26 at both ends can be detachable or telescopic. A limiting hole 27 is provided on the limiting rod 26. A subsequent cleaning pipe 28 for cleaning is inserted into the limiting hole 27. An outwardly scattering spray head 29 is installed at the end of the cleaning pipe 28. Even when the length of the left frame 2 and the right frame 3 is extended or retracted, the spray head 29 can cover most areas during bulk spraying.

[0060] It is worth noting that since the left frame 2 and the right frame 3 are in telescopic motion, when the telescope becomes longer, the original spray head 29 will move outward, resulting in the spray head 29 at the original intersection being unable to spray. Therefore, the best sliding match with the limit rod 26 is not an embedded telescopic, but a cross-type telescopic. Even if the embedded telescopic, the spray head 29 sprays across the area, which can also meet the cleaning requirements.

[0061] As an embodiment, the reciprocating motion of the cleaning component 1 is equipped with a driving component 30. In order to better reduce costs, simplify the structure, and improve safety, the driving component 30 includes two groups, an upper group and a lower group. The driving component 30 includes a driving frame 31, and a double-groove driving roller 32 is rotatably mounted on the driving frame 31. A steel wire rope 33 is wound in each groove, and one end of the steel wire rope 33 is connected to the cleaning component 1. A driving gear 34 is fixed at the end of the double-groove driving roller 32. The driving gear 34 is meshed with a driving pinion 35, and the driving pinion 35 is coaxially connected to a driving motor 36.

[0062] It should be noted that the driving motor 36 is connected to the controller.

[0063] In more detail, a driving assembly 30 is fixed at the upper and lower ends of the tower respectively, the steel wire rope 33 of the driving motor 36 at the upper end is connected to the upper end of the cleaning assembly 1, and the steel wire rope 33 of the driving motor 36 at the lower end is connected to the lower end of the cleaning assembly 1. When the driving motor 36 at the upper end is wound, the driving motor 36 at the lower end is released, and when the driving motor 36 at the upper end is released, the driving motor 36 at the lower end is wound. When the cleaning assembly 1 moves from the lower end to the end, a signal is sent through the limit sensor, causing the cleaning assembly 1 to start moving in the opposite direction to achieve reciprocating cleaning.

[0064] It should also be noted that, in order to better achieve the sliding of the steel wire rope 33, guide wheels are fixed to the lower end and the upper end of the tower pole.

[0065] As an embodiment, if the driving assembly 30 at the upper end fails, causing the double-grooved driving roller 32 to reverse, the wire rope 33 at the upper end will lose tension, causing the cleaning assembly 1 to fall rapidly and be damaged. Therefore, a gear groove 37 is provided on the end face of the driving gear 34, and a brake disc frame 38 is fixed in the gear groove 37. The brake disc frame 38 is fixed on the driving frame 31. A sliding box 39 is fixed in the middle of the gear groove 37. The sliding box 39 is square and has sliding openings for sliding in four directions. A sliding rod 40 placed in the brake disc frame 38 is slidably installed inside and outside the sliding box 39. A compression spring 41 is sleeved on the sliding rod 40. A brake disc 42 is fixed to the end of the sliding rod 40. A rack 43 is provided on the side of the sliding rod 40, and the rack 43 is meshed with a one-way wheel 44.

[0066] It should be noted that the one-way wheel 44 includes a rotating outer gear and an inner wheel fixed inside, a rotating pawl is provided between the inner wheel and the outer gear, and a spring is provided between the pawl and the inner wheel.

[0067] In more detail, in order to prevent the cleaning component 1 from falling accidentally, when the driving motor 36 fails and causes the double-grooved driving roller 32 to reverse, the gravity of the cleaning component 1 causes the double-grooved driving roller 32 to reverse rapidly. Initially, the sliding rod 40 is placed on the inner side of the one-way wheel 44. During normal operation, the sliding rod 40 will not contact the one-way wheel 44. Only when it reverses rapidly, the sliding rod 40 is thrown out through the one-way wheel 44, and the brake disc 42 presses against the brake disc frame 38 to decelerate. When the speed is reduced, the ratchet presses against the outer gear and cannot reverse, thereby temporarily stopping the double-grooved driving roller 32 and waiting for subsequent maintenance. At the same time, the one-way wheel 44 and the brake disc 42 wait for subsequent manual reset.

[0068] As an embodiment, the cleaning component 1 is also equipped with a climbing pole component 45, which includes a vertical fixed pole 46, and both sides of the fixed pole 46 are rotatably connected with semicircular climbing frames 47. The ends of the two climbing frames 47 are connected by plugs and slot fixing pins. The climbing frame 47 is provided with two rows of rollers 48 arranged in an annular manner. The steel wire rope 33 of the above-mentioned driving component 30 is connected to the climbing pole component 45, and a water tank 49 is fixed on the outside of the fixed pole 46. A water pump 50, a solenoid valve 51, and a cleaning pipe 28 are installed on the upper end of the water tank 49. The cleaning pipe 28 is connected and inserted into the above-mentioned limiting hole 27.

[0069] It should be noted that the water pump 50 and the solenoid valve 51 are connected to the controller.

[0070] In more detail, the cleaning component 1 and the climbing pole component 45 are arranged as a split structure to reduce weight. The two climbing frames 47 are rotated to open, wrapped around the tower pole, and fixed with plugs, slots, and fixing pins. At this time, the roller 48 is attached to the tower pole, and the climbing pole component 45 follows the upper drive component 30 and the lower drive component 30 The wire rope 33 is pulled to reciprocate up and down. At the same time, the water tank 49 and the cleaning pipe 28 synchronously follow the cleaning component 1 to move up and down. First, the weight of the cleaning component 1 is reduced, second, the length of the cleaning pipe 28 is reduced, third, the cleaning pipe 28 is prevented from being entangled, and fourth, an additional layer of safety protection is provided for the follow-up.

[0071] As an embodiment, in order to further improve safety, the cleaning component 1 and the climbing pole component 45 are connected via a wire rope 33. At this time, the driving component 30 is connected to the cleaning component 1, the cleaning component 1 is connected to the climbing pole component 45, and the driving component 30 is connected to the climbing pole component 45. The three are interconnected to achieve multiple safety guarantees.

[0072] As an embodiment, the rollers 48 are provided in two rows, each row is evenly distributed in a circle, and each row is provided with four rollers 48. Two adjacent rollers 48 in the lower row are coaxially connected with a reversing bevel gear 52, one of which is meshed with a driving bevel gear 53. The driving bevel gear 53 is coaxially fixedly connected with a metal column 54. The end of the metal column 54 is rotatably installed in a sleeve 55. An electromagnet is arranged in the sleeve 55. The other end of the sleeve 55 is coaxially fixedly connected with a first worm gear 56. The first worm gear 56 is meshed with a double-tooth worm gear 57 with a double worm. The other worm of the double-tooth worm gear 57 is meshed with a second worm gear 58. The second worm gear 58 is coaxially fixed with a disc 59. A first connecting rod 60 is eccentrically installed on the disc 59. The first connecting rod 60 is hinged with a second connecting rod 61. The end of the second connecting rod 61 is hinged with a sliding deceleration plate 62. The double-tooth worm gear 57 is connected to a servo motor 63.

[0073] It should be noted that an upper slide plate and a lower slide plate are fixed at the upper end and the lower end between the two rollers 48 , a deceleration plate 62 is slidably installed between the upper slide plate and the lower slide plate, and a servo motor 63 is connected to the double-tooth worm 57 .

[0074] It should be noted that the servo motor 63 is connected to the controller, and a speed sensor 64 is installed on the climbing pole assembly 45, the speed sensor 64 is connected to the controller, the speed sensor 64 is connected to the electromagnet, and the electromagnet is connected to the controller.

[0075] In more detail, when the wire rope 33 breaks, causing the climbing pole assembly 45 to fall rapidly, the speed sensor 64 detects that the speed range is exceeded and sends a signal to the servo motor 63. The servo motor 63 starts to start, and the servo motor 63 drives the double-tooth worm 57 to rotate. The double-tooth worm 57 engages the second worm gear 58 to rotate, and the second worm gear 58 drives the disc 59 to rotate. The disc 59 drives the first connecting rod 60 and the second connecting rod 61 to rotate, and the second connecting rod 61 pushes the deceleration plate 62 to stick to the tower pole to slow down.

[0076] The speed sensor 64 sends a signal to energize the electromagnet, so that the sleeve 55 and the metal column 54 are fixedly connected, the double-toothed worm 57 meshes with the first worm gear 56 to rotate, the first worm gear 56 drives the driving bevel gear 53 to rotate, the driving bevel gear 53 meshes with the reversing bevel gear 52 to rotate, and the reversing bevel gear 52 drives the roller 48 to rotate upward, decelerating and stopping the climbing pole assembly 45. After the climbing pole assembly 45 stops moving, the speed sensor 64 sends a signal to the servo motor 63 to stop. At this time, the deceleration plate 62 is close to the tower pole to achieve deceleration and stop, and the double-toothed worm 57 and the second worm gear 58 prevent the deceleration plate 62 from resetting.

[0077] It should be noted that, initially, the climbing pole assembly 45 moves up and down normally, the roller 48 rotates normally, the electromagnet is not energized, and the reversing bevel gear 52 and the driving bevel gear 53 rotate idly.

[0078] It should be noted that the double-tooth worm 57 , the first worm gear 56 , the second worm gear 58 , the reversing bevel gear 52 , and the driving bevel gear 53 are installed with corresponding bearing seats.

[0079] As an embodiment, since part of the tower pole is conical, narrow at the top and wide at the bottom, in order to ensure that the roller 48 is close to the tower pole when the climbing pole assembly 45 moves up and down, the upper row of rollers 48 are rotatably installed on a roller plate 65, and a sliding hole for lateral adjustment is opened on the roller plate 65. A compression spring 66 is arranged in the sliding hole, and one end of the compression spring 66 is connected to the roller 48, so that the roller 48 at the upper end can move and adaptively adjust at any time, so that the roller 48 follows the size changes of the tower pole and sticks to the tower pole.

[0080] The present invention has the following technical effects.

[0081] 1. The present invention can realize automatic cleaning of the fan blades through the reciprocating motion of the cleaning component, and no longer needs to be cleaned manually by high-altitude operations, thus avoiding the risks brought by manual high-altitude cleaning.

[0082] 2. The present invention is connected by sliding between the left frame and the right frame, and can automatically achieve extension and retraction in the left and right directions in conjunction with a distance sensor to adapt to the left and right length cleaning of the fan blades. It also applies pressure to the cleaning belt against the fan blades through the rotatably connected main pressure roller and the rotatably connected secondary pressure roller, and then cooperates with the main cylinder and the secondary cylinder to adjust the main pressure roller and the secondary pressure roller in the up and down directions, and then follows the reciprocating motion to complete the cleaning of the fan blades.

[0083] 3. The present invention simultaneously connects the cleaning component through the up and down direction driving components, so that the cleaning component can reciprocate on the fan blades for cleaning, and the driving component can achieve slow movement through the engagement of the driving small gear and the driving large gear. If the driving motor fails and causes reverse rotation and falling, the brake disc will automatically decelerate the driving large gear to avoid damage caused by rapid falling of the cleaning component.

[0084] 4. The present invention realizes a separate climbing pole through a climbing pole assembly, and installs a water tank on the climbing pole assembly. The water tank and the cleaning assembly are separately arranged to reduce the weight of the cleaning assembly. The water tank moves up and down with the cleaning assembly, which reduces the length of the water pipe and avoids the entanglement of the water pipe during the reciprocating motion. In addition, if the wire rope breaks, the climbing pole assembly can decelerate the climbing pole assembly through the cooperation of the servo motor, roller and deceleration plate to prevent the water tank from falling rapidly and causing damage.

[0085] 5. The present invention reduces the overall weight by separately arranging the cleaning component, the driving component, and the climbing pole component. At the same time, the three are connected separately by steel wire ropes to increase the connection relationship among the three. Even if one of them has an accident, the remaining two can restrain each other, thereby increasing safety protection and achieving multiple safety guarantees.

After reading the above content, various modifications and substitutions of the present invention will be obvious to those skilled in the art. Therefore, the protection scope of the present invention should be defined by the attached claims.
