Description

Technical Field

[0001] This application belongs to the field of wind turbine inspection technology, specifically relating to a traction wind turbine inspection device. Background Technology

[0002] In the wind power industry, the operating status of wind turbines directly affects power generation efficiency and equipment lifespan. However, because wind turbines are usually installed at high altitudes or in complex environments, their inspection and maintenance are challenging. Traditional wind turbine inspection methods mainly rely on manual checks, requiring personnel to approach or enter the vicinity of the turbine equipment for inspection. This method is not only inefficient but also poses significant safety hazards, especially in high-temperature, high-humidity, or dusty production environments, where manual inspections are difficult to conduct for extended periods.

[0003] In recent years, track-mounted inspection robots have emerged. These robots are automatically controlled and driven along a designated route by traction, which can save manpower and is easy to operate. However, in existing equipment, steel cables are often directly connected to the robot to pull it along, which makes it difficult to guarantee the stability of the robot's movement and affects the reliability of the wind turbine inspection results.

[0076] The preferred embodiments of this application are described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0077] like Figure 1 and Figure 2As shown in the embodiment of this application, a traction-type wind turbine inspection device is proposed, comprising: a support frame 1, a drive assembly 2, a traction rope loop 3, a traveling seat assembly 4, a rotating seat assembly 5, and a detection device assembly 6; the drive assembly 2 is mounted on the support frame 1 and includes two drive wheels 22; the traction rope loop 3 is wound around the outside of the two drive wheels 22, and the drive wheels 22 drive the traction rope loop 3 to move; the traveling seat assembly 4 is mounted on the traction rope loop 3 and is connected to one section of the traction rope loop 3 so that the traveling seat assembly 4 moves with the traction rope loop 3; the traveling seat assembly 4 includes a limiting wheel group 41, which surrounds a limiting cavity, and the traction rope loop 3 is embedded in the limiting cavity, and the limiting wheel group 41 makes rolling contact with the other section of the traction rope loop 3; the rotating seat assembly 5 is mounted on the traveling seat assembly 4 and includes a rotating disk 51, which is rotatably connected to the traveling seat assembly 4; the detection device assembly 6 is mounted on the rotating disk 51 to detect the wind turbine status.

[0078] The traction-type wind turbine inspection device provided in this application embodiment includes a support frame 1, a drive assembly 2, a traction rope loop 3, a traveling seat assembly 4, a rotating seat assembly 5, and a detection device assembly 6. The traction rope loop 3 is wound around the outside of two drive wheels 22. The rotation of the drive wheels 22 of the drive assembly 2 drives the traction rope loop 3 to move, which in turn drives the traveling seat assembly 4 on the traction rope loop 3 to move. The detection device assembly 6 is mounted on a rotating disk 51, which is rotatably connected to the traveling seat assembly 4. The rotating disk 51 drives the detection device assembly 6 to rotate. As the detection device assembly 6 moves with the traction rope loop 3, its orientation changes. When the inspection device moves to different positions, it can perform real-time detection of the wind turbine, realizing the mobile detection of the wind turbine. The walking seat assembly 4 is fixedly connected to one section of the traction rope loop 3, and the walking seat assembly 4 is movably connected to the other section of the traction rope loop 3 through the limit wheel set 41. The two sections of traction rope loop 3 are used to support the detection device assembly 6, which improves the stability of the detection device assembly 6 as it moves with the traction rope loop 3. The movable connection between the limit wheel set 41 and the traction rope loop 3 improves the smoothness of the walking assembly as it moves with the traction rope loop 3, thereby reducing the shaking of the detection device assembly 6 and improving the reliability of the detection results.

[0079] Furthermore, the drive assembly 2 includes two drive motors 21 and two drive wheels 22, with each drive motor 21 corresponding to one drive wheel 22. The output shafts of the two drive motors 21 rotate synchronously, thereby driving the traction rope loop 3 to move simultaneously through the two drive wheels 22, so as to provide sufficient driving force and prevent the traction rope loop 3 from slipping.

[0080] Understandably, when the traction rope loop 3 is wrapped around the outside of the two drive wheels 22, two sections of the traction rope loop 3 between the two drive wheels 22 are visible. The walking seat assembly 4 is fixed on one section of the traction rope loop 3. The walking seat assembly 4 and the other section of the traction rope loop 3 are movably connected through the limiting wheel set 41. The other section of the traction rope loop 3 provides auxiliary support for the inspection device. While improving the walking stability of the inspection device, the limiting wheel set 41 makes rolling contact with the traction rope loop 3, thus not interfering with the normal walking of the traction rope loop 3, avoiding jamming of the traction rope loop 3 and the inspection device, and ensuring the smooth walking of the inspection device.

[0081] like Figure 3 As shown, in one feasible embodiment, the detection device component 6 includes: an infrared camera 61, a visual camera 62, an acoustic sensor 63, a laser velocimeter 64, and a gas sensor 65; the infrared camera 61 is used to collect heat information of the fan and the environment; the visual camera 62 is used to collect image information of the fan and the environment; the acoustic sensor 63 is used to collect sound wave information generated by the fan; the laser velocimeter 64 is used to collect the rotational speed information of the fan; and the gas sensor 65 is used to collect gas flow rate information outside the fan.

[0082] In this technical solution, multiple detection devices are arranged on the rotating base. A vision camera 62 acquires real-time images of the fan and the environment to facilitate the positioning of the inspection device itself and to directly determine the fan status through the images. An infrared camera 61 acquires a heat map of the fan and the environment, and an acoustic sensor 63 detects the magnitude of the sound waves generated by the fan. After being aligned, the laser speed sensor 64 remotely and accurately measures the fan speed by emitting a laser to determine the fan status. By using multiple detection devices to detect the fan status simultaneously, the accuracy and completeness of the fan detection results are ensured to the greatest extent.

[0083] Furthermore, the infrared camera 61, the visual camera 62, the acoustic sensor 63, the laser speed sensor 64, and the gas sensor 65 are all oriented in the same direction on the rotating disk 51, so that after the rotating disk 51 rotates at any angle, the infrared camera 61, the visual camera 62, the acoustic sensor 63, the laser speed sensor 64, and the gas sensor 65 will still be oriented in the same direction.

[0084] like Figure 2 and Figure 4As shown, in one feasible embodiment, the walking seat assembly 4 includes multiple limiting wheel sets 41, each limiting wheel set 41 including: an inner limiting wheel 411 and an outer limiting wheel 412; the inner limiting wheel 411 is arranged inside the traction rope loop 3 and rolls in contact with the traction rope loop 3; the outer limiting wheel 412 is arranged outside the traction rope loop 3 and rolls in contact with the traction rope loop 3; the outer limiting wheel 412 and the inner limiting wheel 411 form a limiting cavity, and the outer limiting wheel 412 and the inner limiting wheel 411 are staggered.

[0085] In this technical solution, a limiting wheel assembly 41 includes an inner limiting wheel 411 and an outer limiting wheel 412. The inner limiting wheel 411 and the outer limiting wheel 412 clamp the traction rope loop 3, limiting it on both sides. This ensures the stability of the traveling seat assembly 4 as it travels with the traction rope loop 3 without interfering with its movement, preventing the traveling seat assembly 4 from detaching from the traction rope loop 3 and thus preventing the inspection device from falling. By staggering the outer limiting wheel 412 with the inner limiting wheel 411, the contact length between the limiting wheel assembly 41 and the traction rope loop 3 is increased, further improving the stability of the traveling seat assembly 4 as it travels with the traction rope loop 3.

[0086] like Figure 2 and Figure 4 As shown, in one feasible embodiment, the walking seat assembly 4 further includes: a seat plate 42, a clamping device 43, and a reversing trigger 44; the seat plate 42 is disposed above the traction rope loop 3, and a limiting wheel set 41 is disposed on the bottom surface of the seat plate 42, the limiting wheel set 41 connecting the seat plate 42 to the traction rope loop 3; the clamping device 43 is disposed on the bottom surface of the seat plate 42 and is arranged inside the traction rope loop 3; the clamping device 43 includes a drive box 431 and a clamping assembly 432, the clamping assembly 432 is slidably connected in the drive box 431, the clamping assembly 432 cooperates with the limiting wheel set 41 to clamp one section of the traction rope loop 3; the reversing trigger 44 is disposed at both ends of the seat plate 42, the reversing trigger 44 is connected to the clamping assembly 432, and the reversing trigger 44, by contacting the support frame 1, causes the clamping assembly 432 to move and clamp another section of the traction rope loop 3.

[0087] In this technical solution, the clamping device 43 and the limiting wheel set 41 are both set on the bottom surface of the seat plate 42. The seat plate 42 is fixedly connected to one section of the traction rope loop 3 through the clamping device 43 so that the seat plate 42 can move with the traction rope loop 3. The seat plate 42 is movably connected to another section of the traction rope loop 3 through the limiting wheel set 41 so that the limiting wheel set 41 can contact the other section of the traction rope to support the seat plate 42 without interfering with the movement of the traction rope loop 3. The clamping assembly 432, in conjunction with the limiting wheel set 41, clamps and fixes one section of the traction rope loop 3 onto the traveling seat assembly 4, thereby driving the seat plate 42 to move between the two drive wheels 22 via the traction rope loop 3. A reversing trigger 44 is provided at both ends of the seat plate 42. When the reversing trigger 44 at one end of the seat plate 42 contacts the support frame 1, the support frame 1 pushes the reversing trigger 44 to move, causing the clamping assembly 432 to move and clamp the other section of the traction rope loop 3, so that the traveling seat assembly 4 moves in the opposite direction along with the other section of the traction rope loop 3. By having the reversing trigger 44 contact the support frame 1, the position of the traveling seat assembly 4 on the traction rope loop 3 is switched, allowing the traveling seat assembly 4 to reciprocate between the two drive wheels 22 without requiring the drive assembly 2 to reverse, thus preventing damage caused by frequent starts, stops, and reversals of the drive assembly 2 and extending the service life of the inspection device.

[0088] Existing inspection devices control the robot's direction and speed by reversing the motor, which requires frequent starting, stopping, and reversing, resulting in severe motor wear and a short lifespan. Furthermore, multiple sets of limit sensors and corresponding automated equipment and programs are needed to ensure real-time control of the robot's position and direction of movement, leading to high operating costs and complex device design and maintenance procedures. The inspection device of this application, however, triggers automatic reversal when the seat plate 42 reaches its end (near the end of the support frame 1), switching the clamping point of the clamping device 43 to the other side. This allows the seat plate 42 to reciprocate between the two drive wheels 22 via the traction rope loop 3. The structure is simple, requiring no complex hardware and program control, making design and maintenance easier. The drive motor 21 of the inspection device also has a longer service life, eliminating the need for frequent maintenance.

[0089] For ease of explanation, the two traction rope loops 3 between the drive assembly 2 are referred to as the first rope body (one traction rope loop 3) and the second rope body (the other traction rope loop 3), respectively. Since the first rope body and the second rope body are parallel, when the traction rope loop 3 moves, the moving direction of the first rope body is parallel to and opposite to the moving direction of the second rope body. When the inspection device is fixed to the first rope body by the clamping assembly 432, the moving direction of the inspection device is consistent with the moving direction of the first rope body. When the reversing trigger 44 contacts the support frame 1, the reversing trigger 44 drives the clamping mechanism. The component 432 moves, causing the clamping component 432 to clamp the second rope, thereby fixing the inspection device onto the second rope. Since the travel direction of the second rope is opposite to that of the first rope, after the inspection device is fixed to the second rope by the clamping component 432, the travel direction of the inspection device is also opposite to the previous travel direction. This allows the travel direction of the inspection device to be switched by contacting the corresponding end of the support frame 1 with the reversing contact element, without the need for the drive wheel 22 to reverse, thus avoiding wear on the drive component 2 and extending the service life of the inspection device.

[0090] like Figure 1 and Figure 2 As shown, in one feasible implementation, the support frame 1 is provided with a reversing trigger head 7 at both ends, and the seat plate 42 moves between the two reversing trigger heads 7. The reversing trigger head 7 corresponds one-to-one with the reversing trigger element 44.

[0091] In this technical solution, a reversing trigger head 7 is provided at each end of the support frame 1. The seat plate 42 moves between the two reversing trigger heads 7. The reversing trigger member 44 contacts the corresponding reversing trigger member 44 at one end, so that the reversing trigger member 44 moves, thereby driving the clamping device 43 to move and clamp another section of traction rope loop 3, thereby changing the moving direction of the seat plate 42, so that the seat plate 42 reciprocates between the two reversing trigger heads 7.

[0092] like Figures 4 to 6As shown, in one feasible embodiment, the drive housing 431 includes: a housing 4311 and two fixed magnetic blocks 4312; the housing 4311 is fixedly connected to the bottom surface of the base plate 42; the fixed magnetic blocks 4312 are respectively fixedly connected to two opposite inner walls of the housing 4311; the clamping assembly 432 includes: a sliding rod 4321, a first clamping member 4322, a second clamping member 4323, and a movable magnetic block 4324; the sliding rod 4321 passes through the housing 4311 and the fixed magnetic blocks 4312, the sliding rod 4321 is slidably connected to the housing 4311, and the sliding rod 4321 is slidably connected to the fixed magnetic blocks 4312. 2. Sliding connection; The first clamping member 4322 is disposed at the first end of the sliding rod 4321, and the first clamping member 4322 is located inside one section of the traction rope loop 3; The second clamping member 4323 is disposed at the second end of the sliding rod 4321, and the second clamping member 4323 is located inside the other section of the traction rope loop 3; The movable magnetic block 4324 is embedded in the housing 4311, and the movable magnetic block 4324 is fixedly connected to the sliding rod 4321. The sliding rod 4321 drives the movable magnetic block 4324 to move between two fixed magnetic blocks 4312, and the movable magnetic block 4324 and the fixed magnetic blocks 4312 are connected by magnetic force.

[0093] In this technical solution, under the limiting action of the reversing trigger head 7, the reversing trigger member 44 drives the clamping assembly 432 to move, that is, the sliding rod 4321, the first clamping member 4322, the second clamping member 4323, and the movable magnetic block 4324 move synchronously; the movable magnetic block 4324 is set inside the housing 4311, and the movable magnetic block 4324 is located between two fixed magnetic blocks 4312. The reversing trigger member 44 drives the movable magnetic block 4324 to move, so that the movable magnetic block 4324 is alternately magnetically attracted to the two fixed magnetic blocks 4312. On 312, the first clamping member 4322 clamps one section of the traction rope loop 3 by cooperating with the limiting wheel group 41, or the second clamping member 4323 clamps the other section of the traction rope loop 3 by cooperating with the limiting wheel group 41. Then, the reversing trigger member 44 contacts the corresponding reversing trigger head 7, so that the clamping assembly 432 alternately clamps the two sections of the traction rope loop 3, thereby allowing the inspection device to be alternately clamped and fixed on the two sections of the traction rope loop 3. Without the need for the drive assembly 2 to reverse, the automatic reversing of the inspection device's movement is achieved.

[0094] Furthermore, the fixed magnetic block 4312 and the movable magnetic block 4324 have opposite magnetic poles, and both the fixed magnetic block 4312 and the movable magnetic block 4324 are permanent magnets.

[0095] It should be noted that the limit wheel set 41 is provided in multiple sets. The first clamping member 4322 and the second clamping member 4323 cooperate with different limit wheel sets 41 to clamp the two sections of traction rope loop 3 respectively.

[0096] like Figure 4As shown, in one feasible embodiment, there are two clamping devices 43, and the clamping device 43 further includes: a first connecting plate 433 and a second connecting plate 434; the first end of the first connecting plate 433 is fixedly connected to one of the first clamping members 4322, and the second end of the first connecting plate 433 is fixedly connected to the other first clamping member 4322, so that the two first clamping members 4322 move synchronously; the first end of the second connecting plate 434 is fixedly connected to one of the second clamping members 4323, and the second end of the second connecting plate 434 is fixedly connected to the other second clamping member 4323, so that the two second clamping members 4323 move synchronously.

[0097] In this technical solution, the first clamping members 4322 on the two clamping devices 43 are connected by the first connecting plate 433 so that the two first clamping members 4322 move synchronously. This ensures that when the clamping assembly 432 moves and changes direction with the reversing trigger 44, the two first clamping members 4322 simultaneously clamp the traction rope loop 3, improving the clamping firmness. The second clamping members 4323 on the two clamping devices 43 are connected by the second connecting plate 434 so that the two second clamping members 4323 move synchronously. This ensures that when the clamping assembly 432 moves and changes direction with the reversing trigger 44, the two second clamping members 4323 simultaneously clamp the traction rope loop 3, improving the clamping firmness. This ensures the synchronicity of the walking seat assembly 4 and the traction rope loop 3, prevents the walking seat assembly 4 from slipping during walking, and helps improve the accuracy of inspection results.

[0098] Furthermore, four limit wheel sets 41 are provided, with each clamping device 43 corresponding to two limit wheel sets 41. The two limit wheel sets 41 are located on both sides of the clamping device 43. They cooperate with the two outer limit wheels 412 through the first clamping member 4322 and the second clamping member 4323 to clamp the two sections of traction rope loop 3 respectively.

[0099] like Figure 4 As shown, in one feasible embodiment, there are two clamping devices 43, and the traveling seat assembly 4 further includes: a reversing connecting plate 45; the reversing connecting plate 45 is arranged parallel to the sliding rod 4321, the first end of the reversing connecting plate 45 is fixedly connected to the first clamping member 4322, and the second end of the reversing connecting plate 45 is fixedly connected to the second clamping member 4323; a reversing trigger member 44 is arranged on the reversing connecting plate 45, the two reversing trigger members 44 are arranged symmetrically at the center, and the center of symmetry of the two reversing trigger members 44 is the center of the seat plate 42; a first inclined surface is provided on the reversing trigger member 44, and a second inclined surface is provided on the reversing trigger head 7, the second inclined surface being adapted to the first inclined surface.

[0100] In this technical solution, the reversing trigger 44 is connected to the first clamping member 4322 via a reversing connecting plate 45, and the reversing trigger 44 is connected to the second clamping member 4323 via a reversing connecting plate 45, to ensure the synchronicity of the movement of the first clamping member 4322 and the second clamping member 4323 with the reversing trigger 44; the reversing trigger 44 is provided with a first inclined surface, and the reversing trigger head 7 is provided with a second inclined surface. The contact length between the first inclined surface and the second inclined surface gradually increases, so that the second inclined surface limits the first inclined surface, thereby causing the reversing trigger 44 to drive the clamping assembly 432 to move; the reversing triggers 44 on the base plate 42 are centrally symmetrically arranged, and the two first inclined surfaces face opposite directions, so that the first inclined surface contacts the corresponding second inclined surface on the reversing trigger head 7, causing the reversing triggers 44 at both ends to move. The movement directions of 4 are opposite, and the reversing trigger 44 drives the movable magnetic block 4324 to reciprocate between the two fixed magnetic blocks 4312 and magnetically attract it to the fixed magnetic block 4312. One reversing trigger 44 can only trigger one clamping device 43 to move. By connecting the first clamping member 4322 on the two clamping devices 43 with the first connecting plate 433, and connecting the second clamping member 4323 on the two clamping devices 43 with the second connecting plate 434, it is ensured that the two clamping devices 43 can move synchronously, clamp the traction rope loop 3 together, and reset the clamping device 43 that is far away from the reversing trigger 44 that is braking, so that the clamping action of the two clamping devices 43 can be connected and continuous, ensuring the timeliness of the reversing of the inspection device, and realizing the automatic reversing of the inspection device without external independent control.

[0101] In this technical solution, the contact surface between the reversing trigger 44 and the reversing trigger head 7 is an inclined surface, so that the contact mode between the reversing trigger 44 and the reversing trigger head 7 is a continuous sliding contact line contact. This allows the reversing trigger 44 to separate the traction rope loop 3 from the first clamping member 4322 / second clamping member 4323 only when it moves to the end of the travel trajectory, and allows the second clamping member 4323 / first clamping member 4322 to quickly clamp the traction rope loop 3, thereby improving the timeliness of the inspection device's reversal.

[0102] It is understandable that the first inclined surfaces on the two reversing triggers 44 face opposite directions, and the second inclined surfaces are set in accordance with the corresponding first inclined surfaces. Therefore, the second inclined surfaces on the two reversing trigger heads 7 also face opposite directions.

[0103] like Figure 5 As shown, in one feasible embodiment, the traction wind turbine inspection device further includes: a first receiving groove 8 and a second receiving groove 9; the first receiving groove 8 is disposed on the side wall of the first clamping member 4322 near the traction rope loop 3, and the shape of the first receiving groove 8 is adapted to the cross-sectional shape of the traction rope loop 3; the second receiving groove 9 is disposed on the side wall of the second clamping member 4323 near the traction rope loop 3, and the shape of the second receiving groove 9 is adapted to the cross-sectional shape of the traction rope loop 3.

[0104] In this technical solution, the first clamping member 4322 is provided with a first receiving groove 8 for accommodating the traction rope loop 3, and the shape of the first receiving groove 8 is adapted to the cross-sectional shape of the traction rope loop 3 to increase the contact area between the first clamping member 4322 and the traction rope loop 3, thereby increasing the friction between the first clamping member 4322 and the traction rope loop 3 and ensuring the stability of the clamping of the traction rope loop 3 by the first clamping member 4322; the second clamping member 4323 is provided with a second receiving groove 9 for accommodating the traction rope loop 3, and the shape of the second receiving groove 9 is adapted to the cross-sectional shape of the traction rope loop 3 to increase the contact area between the second clamping member 4323 and the traction rope loop 3, thereby increasing the friction between the second clamping member 4323 and the traction rope loop 3 and ensuring the stability of the clamping of the traction rope loop 3 by the second clamping member 4323, thereby preventing the inspection device from slipping and improving the accuracy of the inspection data of the inspection device.

[0105] Furthermore, the first receiving groove 8 is provided with anti-slip texture to further increase the friction between the first clamping member 4322 and the traction rope loop 3 when the first clamping member 4322 clamps the traction rope loop 3, thereby preventing the walking seat assembly 4 from slipping; the second receiving groove 9 is provided with anti-slip texture to further increase the friction between the second clamping member 4323 and the traction rope loop 3 when the second clamping member 4323 clamps the traction rope loop 3, thereby preventing the walking seat assembly 4 from slipping.

[0106] like Figure 7 As shown, in one feasible embodiment, the rotating seat assembly 5 further includes: a rotating base 52, a clearance groove 53, a gear ring 54, a rotating motor 55, and a gear 56; the rotating base 52 is fixedly connected to the traveling seat assembly 4, and the rotating disk 51 is rotatably connected to the rotating base 52; the clearance groove 53 is disposed on the top surface of the rotating base 52; the gear ring 54 is fixedly connected to the bottom surface of the rotating disk 51, the gear ring 54 is coaxially arranged with the rotating disk 51, and the gear ring 54 is embedded in the clearance groove 53; the rotating motor 55 is disposed in the clearance groove 53, and the rotating motor 55 is connected to the rotating base 52; the gear 56 is fixedly connected to the output shaft of the rotating motor 55, and the gear 56 meshes with the gear ring 54 to drive the gear ring 54 to rotate.

[0107] In this technical solution, the rotary motor 55 drives the gear 56 to rotate. The gear 56 meshes with the gear ring 54, thereby driving the rotary disk 51 to rotate on the rotary base 52. The orientation of the detection device component 6 is adjusted by the rotary disk 51 during the movement of the inspection device, thereby expanding the detection range of the inspection device.

[0108] Furthermore, a protective ring 57 is provided on the side wall of the rotating disk 51. The protective ring 57 is arranged around the circumference of the rotating disk 51 and covers part of the rotating base 52 to prevent rainwater from entering the rotating base 52 and reduce dust entry, which helps to extend the service life of the inspection device.

[0109] Working principle:

[0110] First, install the inspection device in place and connect the output signal of the detection device component 6 to the detection system. Start the drive motors 21 at both ends, and the two drive wheels 22 synchronously drive the traction rope loop 3 to move. At this time, the first clamping member 4322 and one of the outer limit wheels 412 clamp one section of the traction rope loop 3. The traction rope loop 3 drives the seat plate 42 to move towards one end of the support frame 1. The detection device component 6 on the rotating disk 51 adjusts its orientation by rotating the seat component 5 to detect the fans along the way. During the detection process, the drive motor 21 can be paused to stabilize the detection device component 6 and improve the detection accuracy. When the seat plate 42 reaches the end, the seat plate 42 and the detection device component 6 automatically turn and move in the opposite direction to perform the detection again. This cycle repeats to achieve automatic inspection. The drive motor 21 keeps running in one direction and does not need to be reversed unless necessary.
