Description

Technical Field

[0001] This invention relates to the field of wind power equipment operation and maintenance testing technology, specifically to a wind turbine generator inspection device. Background Technology

[0002] Maintaining the wind turbine is crucial to ensuring its safe, stable, and efficient operation and extending its service life. By promptly identifying early fault characteristics, preventative maintenance can be performed on various components of the wind turbine.

[0003] As shown in the attached diagram of the instruction manual. Figure 1 As shown, the wind turbine hub (10) is provided with a pitch bearing outer ring (11) and a pitch bearing inner ring (12). A sealing groove (13) for placing an outer sealing strip is provided between the pitch bearing outer ring (11) and the pitch bearing inner ring (12). A support frame (14) is also welded on the pitch bearing outer ring (11). The support frame (14) is used to assist maintenance personnel in working outside the wind turbine nacelle.

[0004] After the wind turbine has been running for a long time, its sealing strip is prone to aging and sticking to the sealing groove (13). The operator needs to stop the unit, lock the impeller to the inverted "Y" position, and lock the blades of the pitch bearing corresponding to the one whose sealing ring needs to be replaced to the vertical upward position. Then, the operator connects to the support frame (14) with a safety rope to carry out the wind turbine nacelle operation. The operator needs to remove the sealing strip from the sealing groove (13) and clean the sealing groove (13) until the metal color of the sealing groove (13) is exposed. Then, use a brush to evenly apply the lubricating medium to the lip of the sealing groove (13) so that a new sealing strip can be installed in the sealing groove (13) later. The whole operation process is not only complicated and time-consuming, but also requires a lot of manual labor and a lot of equipment, making the work inconvenient.

[0005] Based on this, the present invention designs a wind turbine generator inspection device to solve the above problems. Summary of the Invention

[0006] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a wind turbine generator inspection device.

[0015] Furthermore, a squeezing wheel is rotatably mounted on the mounting plate. The squeezing wheel is used to cooperate with a rotating pulley on one side to squeeze the contact medium layer to squeeze out excess liquid on the contact medium layer.

[0016] Furthermore, the uniform lubrication mechanism includes a storage box, a conveying pipe, a fixed plate, and a brush plate. The storage box and the fixed plate are fixedly connected to the mounting frame. The brush plate is fixedly installed on the fixed plate.

[0036] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0037] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0038] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-11 A wind turbine generator inspection device, comprising a frame 20;

[0039] The frame 20 is equipped with a mounting-type moving mechanism 3 for moving around the bearing along the support frame 14. The frame 20 is also equipped with a dual-axis moving mechanism 4. The moving end of the dual-axis moving mechanism 4 is fixedly equipped with a mounting frame 21. The mounting frame 21 is sequentially equipped with a blowing mechanism 8, a groove cleaning mechanism 5, a non-destructive testing mechanism 6, and a uniform lubrication mechanism 7 along the horizontal direction. Furthermore, vision modules 9 are fixedly installed on both the left and right sides of the frame 20.

[0040] The groove cleaning mechanism 5 includes a vertical support assembly 51, a reciprocating drive assembly 52, a cleaning fabric 53, a scraper 54, a cleaning fluid supply assembly 55, and a take-up and unwind assembly 56. The vertical support assembly 51 is fixedly connected to the mounting frame 21. The reciprocating drive assembly 52, the cleaning fluid supply assembly 55, and the take-up and unwind assembly 56 are installed at the moving end of the vertical support assembly 51. The scraper 54 is horizontally slidable at the moving end of the vertical support assembly 51 through a limiting assembly. The output end of the reciprocating drive assembly 52 is fixedly connected to the scraper 54. The output end of the take-up and unwind assembly 56 is equipped with the cleaning fabric 53. The take-up and unwind assembly 56 is used to control the take-up and unwind of the cleaning fabric 53. The scraper 54 is located on the upper side of the cleaning fabric 53 and abuts against it. The take-up and unwind assembly 56 is used to spray cleaning fluid onto the cleaning fabric 53.

[0041] The vertical support assembly 51 can be a lead screw slide.

[0042] In this invention, when the blade corresponding to the pitch bearing whose sealing ring needs to be replaced is locked in a vertically upward state, the frame 20 is quickly deployed on the support frame 14 via the mounting-type moving mechanism 3. After the sealing strip is removed, the groove cleaning mechanism 5, non-destructive testing mechanism 6, uniform lubrication mechanism 7 and purging mechanism 8 are controlled by the dual-axis moving mechanism 4 to contact the sealing groove 13. Then, the frame 20 is controlled by the mounting-type moving mechanism 3 to move around the blade along the support frame 14, and the status of the sealing groove 13 is monitored in real time by the vision module 9.

[0043] During the movement of the frame 20, the blowing mechanism 8, the groove cleaning mechanism 5, the non-destructive testing mechanism 6, and the uniform lubrication mechanism 7 work in sequence. The blowing mechanism 8 blows out the impurities in the sealing groove 13. The vertical support component 51 controls the cleaning fabric 53 and the scraper 54 to move downward, so that the scraper 54 presses against the sealing groove 13. At the same time, the cleaning fabric 53 is placed between the scraper 54 and the sealing groove 13. Under the drive of the reciprocating drive component 52, the scraper 54 moves horizontally back and forth, so that the cleaning fabric 53 scrapes the sealing groove 13 and cleans the adhering objects in the sealing groove 13 until the sealing groove 13 exposes the metal color. Then, the vertical support component 51 controls the cleaning fabric 53 and the scraper 54 to lift up. The unwinding component 56 controls the unwinding and winding of the cleaning fabric 53 to replace the part of the cleaning fabric 53 located between the scraper 54 and the sealing groove 13. Then, the cleaning fluid supply component 55 sprays cleaning fluid onto the cleaning fabric 53 to increase the cleaning efficiency of the cleaning fabric 53 on the sealing groove 13.

[0044] After the sealing groove 13 is cleaned, it is subjected to non-destructive testing by the non-destructive testing mechanism 6 to detect defects in the pitch bearing in a timely manner. Finally, the lubricating medium is evenly applied into the sealing groove 13 by the uniform lubrication mechanism 7 to facilitate the subsequent assembly of the sealing strip.

[0045] In this invention, the mounting mobile mechanism 3 can quickly deploy the frame 20 onto the support frame 14, allowing the frame 20 to move around the blade along the support frame 14. This enables automatic blowing, scraping cleaning, non-destructive testing, and uniform oiling of the sealing groove 13 in sequence, effectively reducing the difficulty of replacing the sealing strip, increasing the efficiency of the sealing strip replacement, and facilitating the subsequent assembly work of the sealing strip by the operators.

[0046] Please see Figure 8 , Figure 9 and Figure 10 The reciprocating motion drive assembly 52 includes a connecting plate 521, a turntable 523, a sliding pin 524, and a drive motor 525. The drive motor 525 is fixedly connected to the moving end of the vertical support assembly 51. The turntable 523 is fixedly installed at the output end of the drive motor 525, and the sliding pin 524 is fixedly installed at the eccentric part of the turntable 523. The connecting plate 521 is fixedly connected to the scraper block 54, and a groove 522 is provided on the connecting plate 521 to be slidably connected to the sliding pin 524.

[0047] The unwinding and take-up assembly 56 includes an unwinding roller 561, an unwinding motor 562, a take-up roller 563, a take-up motor 564, and a tensioning assembly. The unwinding motor 562 and the take-up motor 564 are both fixedly connected to the moving end of the vertical support assembly 51. The unwinding roller 561 is fixedly installed at the output end of the unwinding motor 562, and the take-up roller 563 is fixedly installed at the output end of the take-up motor 564. The tensioning assembly is installed at the moving end of the vertical support assembly 51.

[0048] The tensioning assembly includes a tensioning wheel 565, a spring 567, and a guide rod 568. A movable block 566 is horizontally slidable on the moving end of the vertical support assembly 51 via a limiting assembly. The tensioning wheel 565 is rotatably connected to the movable block 566 via a bearing. One end of the guide rod 568 is fixedly connected to the moving end of the vertical support assembly 51, and the other end is slidably connected to the movable block 566. The spring 567 is sleeved on the outside of the guide rod 568, and both ends of the spring 567 are fixedly connected to the movable block 566 and the moving end of the vertical support assembly 51, respectively.

[0049] The two ends of the cleaning fabric 53 are fixedly connected to the unwinding roller 561 and the take-up roller 563 respectively and are wound around them. The connecting plate 521 passes through the outside of the tensioning wheel 565.

[0050] The cleaning fluid supply assembly 55 includes a storage tank 551, a spray pipe 552, and a nozzle 553. The storage tank 551 is fixedly installed at the moving end of the vertical support assembly 51. One end of the spray pipe 552 is fixedly connected to the storage tank 551, and the other end of the spray pipe 552 is fixedly installed with a nozzle 553 for spraying cleaning fluid onto the cleaning fabric 53. A pump body (not shown in the figure) is also fixedly installed between the storage tank 551 and the spray pipe 552 for pumping out the cleaning fluid.

[0051] In some embodiments, the cleaning fabric 53 is made of a napped fabric, which has high friction and strong dirt absorption capacity.

[0052] In some embodiments, the storage tank 551 contains anhydrous ethanol, which evaporates quickly and has a strong ability to remove aged and adhered sealing strips in the sealing groove 13.

[0053] In this invention, the vertical support assembly 51 moves downward, causing the scraper 54 to press against the sealing groove 13. Simultaneously, the cleaning fabric 53 is placed between the scraper 54 and the sealing groove 13. The drive motor 525 drives the turntable 523 to rotate, and with the cooperation of the sliding pin 524 and the groove 522 on the connecting plate 521, the scraper 54 moves back and forth at high speed in the horizontal direction. The tensioning wheel 565 keeps the cleaning fabric 53 constantly tensioned, causing the cleaning fabric 53 between the scraper 54 and the sealing groove 13 to repeatedly scrape the sealing groove 13, thus sealing the groove. The attachments in the groove 13 are cleaned until the metal of the sealed groove 13 is exposed. Then, the moving end of the vertical support assembly 51 moves upward to separate the cleaning fabric 53 from the sealed groove 13. The unwinding motor 562 and the winding motor 564 control the rotation of the unwinding roller 561 and the winding roller 563 respectively to replace the cleaning fabric 53 located between the scraper block 54 and the sealed groove 13. Then, cleaning liquid is sprayed onto the cleaning fabric 53 through the spray pipe 552 and the nozzle 553 to increase the cleaning efficiency of the cleaning fabric 53 on the sealed groove 13.

[0054] Please see Figure 8 , Figure 9 and Figure 11 The non-destructive testing mechanism 6 includes a mounting plate 61, an ultrasonic probe 62, a contact medium layer 63, rotating pulleys 65, guide wheels 66, and a liquid storage box 67. The mounting plate 61 is fixedly connected to the mounting frame 21, and the liquid storage box 67 is fixedly connected to the mounting plate 61. Two rotating pulleys 65 are distributed on both sides above the liquid storage box 67 and are rotatably connected to the mounting plate 61. The guide wheels 66 rotate inside the liquid storage box 67. The ultrasonic probe 62 is located on the lower side of the liquid storage box 67 and is fixedly connected to the mounting plate 61. The contact medium layer 63 is wrapped around the outer side of the rotating pulleys 65 and the ultrasonic probe 62 and the inner side of the guide wheels 66 to form a closed structure. The liquid storage box 67 is filled with pure water.

[0055] A squeezing wheel 64 is also rotatably mounted on the mounting plate 61. The squeezing wheel 64 is used to cooperate with the rotating pulley 65 on one side to squeeze the contact medium layer 63 and squeeze out the excess liquid on the contact medium layer 63.

[0056] The contact medium layer 63 can be made of fabrics such as fine cotton cloth and gauze.

[0057] In this invention, the dual-axis moving mechanism 4 drives the mounting frame 21 to move downwards, causing the ultrasonic probe 62 to press against the sealing groove 13. When the mounting moving mechanism 3 drives the frame 20 to move along the support frame 14, the contact medium layer 63 rotates around the ultrasonic probe 62, the rotating pulley 65, and the guide wheel 66 under the friction of the sealing groove 13. This keeps the contact medium layer 63 moist by continuously moving in and out of the liquid storage box 67. Excess water is squeezed back into the liquid storage box 67 by the squeezing wheel 64 and the rotating pulley 65. The contact medium layer 63 is placed between the ultrasonic probe 62 and the sealing groove 13, which facilitates the movement and scanning of the ultrasonic probe 62 on the sealing groove 13. This removes air between the ultrasonic probe 62 and the detection surface of the sealing groove 13, resulting in a good coupling effect and ensuring the accuracy and stability of the ultrasonic probe 62's detection results.

[0058] Please see Figure 9 The uniform lubrication mechanism 7 includes a storage tank 71, a conveying pipe 72, a fixing plate 73, and a brush plate 74. The storage tank 71 and the fixing plate 73 are fixedly connected to the mounting frame 21. The brush plate 74 is fixedly installed on the fixing plate 73. The brush plate 74 has a cavity, and multiple through holes are evenly opened at the lower end of the cavity. The two ends of the conveying pipe 72 are respectively connected to the cavity of the storage tank 71 and the brush plate 74. A pump body (not shown in the figure) for conveying lubricating medium is fixedly installed in the storage tank 71.

[0059] In this invention, the dual-axis moving mechanism 4 drives the mounting frame 21 to move down so that the brush of the brush plate 74 fits into the sealing groove 13. When the mounting moving mechanism 3 drives the frame 20 to move along the support frame 14, the pump body pumps the lubricating medium from the storage tank 71 into the cavity of the brush plate 74 through the conveying pipe 72, so that the lubricating medium flows out from the lower end of the brush plate 74 and is evenly coated in the sealing groove 13 with the cooperation of the brush bristles of the brush plate 74, thereby facilitating the subsequent assembly of the sealing strip.

[0060] The blowing mechanism 8 can be a blower / vacuum machine. The blowing mechanism 8 is fixedly installed on the mounting frame 21. The air outlet pipe of the blowing mechanism 8 is inclined downward toward the sealing groove 13. When the mounted moving mechanism 3 drives the frame 20 to move along the support frame 14, the blowing mechanism 8 continuously blows air into the sealing groove 13 to blow out impurities from the sealing groove 13, so as to facilitate the subsequent cleaning operation of the sealing groove 13.

[0061] Please see Figure 5 and Figure 6 The mounted mobile mechanism 3 includes a U-shaped plate 31, upper rollers 33, a mobile motor 34, a side clamping assembly, and auxiliary support rollers 38. Multiple U-shaped plates 31 are fixedly mounted on the upper end of the frame 20. Several upper rollers 33 for rolling on the upper end of the support frame 14 are rotatably mounted on the inner top of the U-shaped plate 31. The mobile motor 34 is fixedly mounted on the upper end of the U-shaped plate 31. The output end of the mobile motor 34 is connected to any upper roller 33 via a transmission assembly, which can be a synchronous belt and synchronous pulley transmission structure. A side clamping assembly for limiting the movement of the upper rollers 33 along the support frame 14 is also mounted on the upper end of the frame 20. Multiple auxiliary support rollers 38 that are rotatably connected to the outer ring 11 of the pitch bearing are rotatably mounted on the lower end of the frame 20.

[0062] The side clamping assembly includes a fixed side roller 35, a movable side roller 37 and an auxiliary support roller 38. The side wall of the U-shaped plate 31 is rotatably mounted with a plurality of fixed side rollers 35 that are rolledly connected to one side of the support frame 14. A push cylinder 36 is fixedly mounted on the frame 20. The output end of the push cylinder 36 is rotatably mounted with a plurality of movable side rollers 37 that are rolledly connected to the other side of the support frame 14.

[0063] The lower end of the U-shaped plate 31 is also provided with a guide ramp 32, which is used to facilitate the operator to hang the upper roller 33 on the support frame 14.

[0064] In this invention, when the blade corresponding to the pitch bearing whose seal needs to be replaced is locked in a vertically upward state, the upper roller 33 is hung on the support frame 14. At this time, due to the center of gravity distribution, the auxiliary support roller 38 of the frame 20 abuts against the outer ring 11 of the pitch bearing, and the fixed side roller 35 abuts against the side of the support frame 14, thus achieving the initial deployment of the frame 20. Subsequently, the movable side roller 37 is moved by the push cylinder 36, so that the fixed side roller 35 and the movable side roller 37 hug and fix the support frame 14 from both sides. Then, the upper roller 33 is driven to rotate by the moving motor 34, so that the frame 20 can move stably around the blade along the support frame 14 to perform related operations. Moreover, the installation and removal of the entire mounted moving mechanism 3 and the support frame 14 are simple, which facilitates the quick deployment of this application by the operators.

[0065] The dual-axis moving mechanism 4 includes a vertical moving linear module 41 and a pushing linear module 42. The vertical moving linear module 41 is fixedly installed on the frame 20. The pushing linear module 42 is fixedly installed at the moving end of the vertical moving linear module 41. The vertical moving linear module 41 is used to drive the pushing linear module 42 to move vertically along the frame 20. The moving end of the pushing linear module 42 is fixedly connected to the mounting frame 21.

[0066] The limiting component can be a slide rail slider limiting structure.
