Description

Technical Field

[0001] This invention relates to the field of blade inspection technology, and more specifically, to an integrated device for grinding lightning arresters and testing lightning protection continuity of wind turbine blades. Background Technology

[0002] Wind turbines, due to their prominent tower height and exposed blade tips, are highly susceptible to lightning strikes. As the core component of the blade lightning protection system, the lightning arrester plays a crucial role in actively intercepting lightning current and safely conducting it to the ground via down conductors. Its conductivity directly determines the lightning protection safety and reliability of the entire unit. During long-term operation, the metal surface of the lightning arrester is prone to oxide layer formation due to exposure to harsh environments such as humidity and salt spray, leading to a significant increase in contact resistance and affecting the smooth conduction of lightning current. Simultaneously, down conductor connections may loosen or corrode due to mechanical vibration, thermal expansion and contraction, or environmental corrosion, potentially creating a risk of open circuit and further blocking the discharge path of lightning current. Furthermore, the blades themselves are mostly made of non-metallic composite materials, lacking natural conductivity. If the conductivity of the lightning protection system deteriorates, lightning may directly puncture the blade structure, causing irreversible damage.

[0003] Traditional inspection relies on manual climbing or suspended baskets for high-altitude operations, which is not only inefficient but also subject to weather and safety risks. While emerging drone or robot inspection technologies avoid the risks of high altitudes, there are still obvious defects in operation. On the one hand, the surface oxide layer is not effectively removed, resulting in distorted resistance measurements. On the other hand, the camera unit of the inspection device is easily contaminated by grinding debris, affecting the clarity of real-time images. To address this, we propose an integrated device for grinding and lightning protection continuity testing of wind turbine blade lightning arresters. Summary of the Invention

A grinding component is disposed inside the grinding portion. A linkage component is disposed inside the grinding component. A cleaning component is disposed outside the grinding portion. An abutment component is disposed inside the cleaning component. The abutment component and the linkage component cooperate to adjust the cleaning component.

[0006] Preferably, the unmanned suspended platform has a downwardly recessed testing platform inside, the testing port corresponds to the testing platform, and a drive motor is provided on the outside of the support base, with the rotor shaft end of the drive motor connected to the center end of the movable base.

[0009] Preferably, the linkage includes multiple sets of telescopic rods arranged circumferentially inside the support frame, and an annular plate is provided on the outer side of the multiple sets of telescopic rods. The annular plate is sleeved on the outer side of the grinding part, and a wave groove is formed at the end of the annular plate away from the telescopic rod.

[0010] Preferably, the cleaning component includes a fixed block disposed on the side wall of the grinding section, an air cylinder disposed on one side of the fixed block, a movable cavity formed inside the air cylinder, an air outlet disposed on the upper end face of the air cylinder, an air outlet correspondingly disposed inside the air outlet, the movable cavity communicating with the air outlet, and a movable plate slidably connected inside the movable cavity.

[0011] Preferably, the abutting member includes an abutting rod disposed on one side of the movable plate, one end of the abutting rod penetrating the air cylinder and contacting the corrugated groove, and a compression spring is sleeved on the outer wall of the abutting rod, one end of the compression spring being disposed on the side wall of the air cylinder.

[0012] Preferably, the device further includes an auxiliary mechanism, which includes a translation component disposed on the driving component, and a leveling component disposed between the two sides of the guiding portion and the grinding portion, wherein the translation component and the leveling component cooperate with each other.

[0013] Preferably, the translation component includes a translation rod disposed on the upper end face of the mounting block, the mounting block having a sliding hole connected to the driving cavity, and the translation rod slidably connected within the sliding hole.

[0014] Preferably, the leveling component includes a telescopic rod one and a telescopic rod two disposed inside the guide section and the grinding section, wherein the telescopic rod one and the telescopic rod two are not on the same horizontal plane, and also includes an auxiliary plate, wherein the telescopic rod one and the telescopic rod two are respectively disposed at both ends of the auxiliary plate, and a counterweight is disposed at the bottom end of the auxiliary plate.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In this invention, the unmanned suspended platform body is moved vertically by the main rope. When the detection port of the unmanned suspended platform comes into contact with the blade tip lightning arrester, as the blade tip lightning arrester enters the position of the detection platform, its conductive part can detect the conduction resistance value of the lightning-attracting channel from the blade tip lightning arrester to the root of the blade. At the same time, the camera captures video and records the contact point, connecting line, tower number and instrument values.

[0017] 2. In this invention, the cylinder drives the mounting block to move within the cavity. As the mounting block moves, it drives two sets of sliders to make a horizontal linear motion within the slide groove. At this time, the grinding head on the detection rod moves outward. The adjustment mechanism then sprays the gas from the air outlet onto the camera, thus ensuring that the debris generated during grinding does not fall onto the outer wall of the camera, thereby ensuring the accuracy of observation by ground personnel.

[0018] 3. In this invention, the translation rod is moved synchronously by the mounting block. When the translation rod moves, the auxiliary plate moves synchronously. At the same time, the position of the counterweight moves. During the translation and grinding process, a reverse balancing torque is continuously provided to ensure the stability of the grinding head when it is working. In addition, the first telescopic plate and the second telescopic plate, together with the auxiliary plate, form a triangular structure. The counterweight is more stable when it moves, avoiding uneven grinding surface caused by vibration.

[0019] 4. In this invention, by moving the unmanned suspended platform body upward, a remote-controlled electric robotic arm extension device is set on one side of the unmanned suspended platform platform to be towed by the intelligent rope climber for the fish-eye-shaped lightning rods distributed on both sides of the blade tip. The ground-operated remote control device makes its conductive part closely fit the lightning rods on both sides of the blade tip, thereby performing a continuity detection operation.

[0029] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0030] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0031] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0032] Example 1 further illustrates the integrated device for grinding and detecting lightning protection continuity of wind turbine blade lightning arresters proposed in this invention. It includes an unmanned suspended platform body 100. Bending portions 101 are formed on both sides of the upper surface of the unmanned suspended platform body 100, and the two bending portions 101 are connected. A detection port 102 is formed between the two bending portions 101. Openings 103 are correspondingly provided on the two bending portions 101. A rotating platform 104 is rotatably connected to the bottom end of the opening 103. A support base 105 is fixedly connected to the upper surface of the rotating platform 104. A movable seat 106 is rotatably connected to the upper surface of the support base 105. A support block 107 is fixedly connected to one end of the movable seat 106. The support block 107 extends outward to form a guide section 108 and a polishing section 109. A camera 110 is detachably installed at the corresponding position on the upper end face of the guide section 108 and the polishing section 109. An adjustment mechanism 200 for auxiliary polishing is also provided inside the support block 107. A detection platform 111 is formed by a downward recess inside the unmanned basket body 100. The detection port 102 corresponds to the detection platform 111. A drive motor 112 is detachably installed on the outside of the support base 105. The rotor shaft end of the drive motor 112 is connected to the center end of the movable base 106. The drive motor 112 drives the movable base 106 to rotate, thereby adjusting the angle of the camera 110.

[0033] Depend on Figures 1 to 3 It is known that its bent part 101 is used to connect the main rope of the wind turbine. The main rope on the wind turbine pulls the unmanned basket body 100 to move vertically. When the detection port 102 of the unmanned basket platform contacts the blade tip lightning arrester, as the blade tip lightning arrester enters the position of the detection platform 111, its conductive part 108 can detect the conduction resistance value of the lightning channel from the blade tip lightning arrester to the root of the blade. At the same time, the camera 110 takes a video and records the contact point, connecting line, tower number and instrument value.

[0034] Because the grinding process generates metal shavings and dust, which obstruct the field of view of the camera 110 and affect the observation of ground personnel, this device is equipped with an adjustment mechanism 200, which includes a driving component 201, a grinding component 202 inside the grinding part 109, a linkage component 203 inside the grinding component 202, a cleaning component 204 outside the grinding part 109, and a contact component 205 inside the cleaning component 204. The contact component 205 and the linkage component 203 cooperate to adjust the cleaning component 204, thereby cleaning the outside of the camera 110 while grinding, ensuring the observation effect of ground personnel. It also includes an auxiliary mechanism 300, which includes a translation component 301 set on the driving component 201 and a leveling component 302 between the two side guide parts 108 and the grinding part 109. The translation component 301 and the leveling component 302 cooperate to ensure the stability of the device during detection.

[0035] When using this device, the personnel climbing the tower must wear safety clothing and shoes as required, check that the slider 201e and double hooks are properly worn, and begin climbing the tower under the supervision of on-site personnel. The personnel climbing the tower shall fix the clamp at one end of the detection wire to the buckle on the waist of the safety belt, and check that the wire connection is secure before starting to climb the tower. During the tower climbing process, the personnel laying the wire below the tower shall not stay below the ladder to prevent falling objects from injuring people. The personnel laying the wire below the tower shall pay attention to the speed of laying the wire at all times to prevent the wire from getting tangled in the wire reel or the ladder as the personnel climb the tower. The personnel laying the wire below the tower may use a walkie-talkie to notify the personnel climbing the tower to control the climbing speed to avoid breaking the wire and causing falling objects to injure people. Once the personnel climbing the tower have safely reached the cabin, they shall notify the personnel below the tower via walkie-talkie before the personnel laying the wire at the bottom of the tower may leave.

[0036] Next, the cabin crew opened the top skylight cover of the cabin, secured one end of the main rope to the insulated counterweight, and fixed the other end of the main rope in the gearbox lifting hole. They then confirmed the operating wind speed, wind direction, and the direction the hub was facing with the ground crew via walkie-talkie. The ground crew needed to adjust the cabin position based on the wind direction, the location of the power collection lines and the generator set, and select the direction to lower the main rope. After confirming the direction, they instructed the cabin crew to begin lowering the main rope via walkie-talkie. During the lowering process, no one was allowed to stand or stay under the counterweight. The ground crew needed to inform the cabin crew of the rope lowering speed based on the on-site wind speed and the counterweight's deviation angle until the counterweight and main rope landed safely.

[0037] Next, the operator operates the unmanned suspended platform 100 to conduct up and down tests on the track rope. During the operation, the system is checked for any abnormal noises, the unmanned suspended platform system is checked to ensure sufficient power and sufficient power during operation, and the electrical control system is checked to ensure that the up and down travel of the unmanned suspended platform system is accurate. Then, the ground operation personnel need to communicate with the cabin operation personnel through walkie-talkie and use yaw operation to adjust the cabin position to ensure that the rope winding position is more than 4 meters away from the 35KV collector line and the generator transformer, and that the rope winding position is downwind of the 35KV collector line and the generator transformer. Then, the main rope is fixed at one end with an insulated counterweight during the rope winding process before the rope winding operation can begin. After the counterweight and the main rope safely reach the ground, the upper end is fixed to the cabin anchor point. The ground operation personnel fix the bent part 101 of the unmanned suspended platform 100 and the lower end is fixed to the ground anchor point.

[0038] As the unmanned suspended platform body 100 moves upward, a remote control motor 202b robotic arm extension device is set on one side of the unmanned suspended platform platform to be towed by the intelligent rope climber for the fish-eye-shaped lightning arresters distributed on both sides of the blade tip. The ground-operated remote control device makes its conduction part 108 close to the lightning arresters on both sides of the blade tip, thereby performing a conduction detection operation.

[0039] Working principle: When using this device, the main rope of the wind turbine is connected to the bend 101 of the unmanned suspended platform body 100. The main rope pulls the unmanned suspended platform body 100 to move vertically. When the detection port 102 of the unmanned suspended platform contacts the blade tip lightning arrester, as the blade tip lightning arrester enters the position of the detection platform 111, its conduction part 108 can detect the conduction resistance value of the lightning-attracting channel from the blade tip lightning arrester to the root of the blade. At the same time, the camera 110 captures video and records the contact point, connecting line, tower number and instrument values. The adjustment mechanism 200 cleans the outside of the camera 110 while the device is being polished to ensure the observation effect of the ground personnel. The auxiliary mechanism 300 ensures the stability during polishing.

[0040] Example 2

[0041] Based on Embodiment 1, the following technical features are added: The adjustment mechanism 200 includes a driving component 201 disposed in the support block 107, a grinding component 202 disposed in the grinding part 109, a linkage component 203 disposed on the inner side of the grinding component 202, a cleaning component 204 disposed on the outer side of the grinding part 109, and an abutment component 205 disposed in the cleaning component 204. The driving component 201 includes a driving cavity 201a disposed in the support block 107. A cylinder 201b is detachably mounted on the upper end face of the bottom end of the driving cavity 201a. An installation block 201c is fixedly connected to the output end of the cylinder 201b. A sliding groove 201d is disposed in the installation block 201c. Two sets of sliders 201e are slidably connected in the sliding groove 201d. A detection rod 201f is fixedly connected to one end of each of the two sliders 201e. A detection head 201g is disposed at one end of one set of detection rods 201f that passes through the conductive part 108.

[0042] Depend on Figures 3 to 8 It can be seen that a square-shaped drive cavity 201a is formed inside the support block 107. A cylinder 201b is detachably installed inside the drive cavity 201a. The cylinder 201b is adjusted by an external controller. The cylinder 201b drives the mounting block 201c to move within the cavity. A T-shaped slide groove 201d is formed inside the mounting block 201c. A T-shaped slider 201e is slidably connected inside the slide groove 201d. While the mounting block 201c moves, it drives the two sets of sliders 201e to make a horizontal linear movement within the slide groove 201d. A detection rod 201f is fixedly connected to one end of each of the two sets of sliders 201e. The detection rod 201f drives the detection head 201g and the grinding head 202c at the other end to grind and detect the blade.

[0043] The grinding component 202 includes a detection rod 201f disposed in the grinding section 109. A motor 202b is detachably mounted on one end of the detection rod 201f. The motor 202b is adjusted by an external controller. A grinding head 202c is fixedly connected to the rotor shaft end of the motor 202b. A support frame 202d is fixedly connected to the inner side of the grinding head 202c. The linkage component 203 includes multiple sets of telescopic rods 203a fixedly connected to the inner side of the support frame 202d in a circular pattern. An annular plate 203b is fixedly connected to the extended end of the multiple sets of telescopic rods 203a. The annular plate 203b is sleeved on the outer side of the grinding section 109. A wave groove 203c is formed at the end of the annular plate 203b away from the telescopic rods 203a.

[0044] Depend on Figures 2 to 8 It is known that a motor 202b is detachably installed at the end of the detection rod 201f. A grinding head 202c is fixedly connected to the output end of the motor 202b. The grinding head 202c is controlled by an external controller to grind the uneven area where the blade is located. A ring-shaped support frame 202d is fixedly connected to the inner side of the grinding head 202c. At the same time, six sets of telescopic rods 203a are fixedly connected in a circular shape inside the support frame 202d. The six sets of telescopic rods 203a are fixedly connected to a ring plate 203b. When the grinding head 202c rotates, it drives the ring plate 203b to rotate. When the ring plate 203b rotates, it drives the wave groove 203c to rotate.

[0045] The cleaning component 204 includes a fixed block 204a fixedly connected to the side wall of the grinding part 109. An air cylinder 204b is fixedly connected to one side of the fixed block 204a. A movable cavity 204c is formed inside the air cylinder 204b. An air outlet 204d is located on the upper end face of the air cylinder 204b. An air outlet 204e is correspondingly provided in the air outlet 204d. The movable cavity 204c communicates with the air outlet 204e. A movable plate 205f is slidably connected inside the movable cavity 204c. The contact component 205 includes a contact rod 205a fixedly connected to one side of the movable plate 205f. One end of the contact rod 205a, which passes through the air cylinder 204b, contacts the wave groove 203c. A compression spring 205b is sleeved on the outer wall of the contact rod 205a. The compression spring 205b is a carbon spring with high strength, which is convenient for daily work. One end of the compression spring 205b is located on the side wall of the air cylinder 204b.

[0046] Because the grinding process generates metal shavings and dust, which obstruct the field of view of camera 110 and affect observation by ground personnel, this device uses an adjustment mechanism 200 to clean the outside of camera 110 simultaneously with grinding, ensuring the observation effect for ground personnel. Figures 1 to 8It can be seen that a cylindrical air cylinder 204b is installed on the side wall of the grinding part 109 via a fixing block 204a, forming a cylindrical movable cavity 204c inside. A movable plate 205f is slidably connected inside the movable cavity 204c. An abutment rod 205a is fixedly connected to the outside of the movable plate 205f. The abutment rod 205a is connected to the side wall of the air cylinder 204b via a compression spring 205b. The abutment rod 205a contacts the wave groove 203c. When the annular plate 203... As b rotates, its wave groove 203c rotates synchronously. Since the contact rod 205a contacts the high and low parts of the wave groove 203c, and due to the restoring force of the compression spring 205b, the movable plate 205f on the contact rod 205a moves in the movable cavity 204c. The movement of the movable plate 205f causes the gas from the vent 204e to be sprayed onto the camera 110, thus ensuring that the debris generated during polishing will not fall onto the outer wall of the camera 110.

[0047] Working principle: During use, the main rope of the fan is connected to the bend 101 of the unmanned suspended platform body 100. The main rope pulls the unmanned suspended platform body 100 to move vertically. When it contacts the uneven part of the blade, the external controller starts the cylinder 201b. The cylinder 201b drives the mounting block 201c to move in the cavity. At the same time, the mounting block 201c drives the two sets of sliders 201e to make horizontal linear movements in the slide groove 201d. At this time, the grinding head 202c on the detection rod 201f moves outward. The external controller starts the motor 202b. While the grinding head 202c rotates, the annular plate 203b also rotates. As the annular plate 203b rotates, the wave groove 203c rotates. Since the contact rod 205a is in contact with the high and low parts of the wave groove 203c, and due to the restoring force of the compression spring 205b, the movable plate 205f on the contact rod 205a moves within the movable cavity 204c. The movement of the movable plate 205f causes the gas from the vent 204e to be sprayed onto the camera 110. This ensures that the debris generated during grinding does not fall onto the outer wall of the camera 110, thus ensuring the accuracy of observation by ground personnel.

[0048] Example 3

[0049] Based on Embodiment 2, the following technical features are added: An auxiliary mechanism 300 is also included. The auxiliary mechanism 300 includes a translation component 301 disposed on the driving component 201, and a leveling component 302 disposed between the two side guide portions 108 and the grinding portion 109. The translation component 301 and the leveling component 302 cooperate to ensure the stability of the device during testing. The translation component 301 includes a translation rod 301a fixedly connected to the upper end face of the mounting block 201c. The mounting block 201c has an elongated sliding hole 301b connected to the driving cavity 201a. The translation rod 301a is slidably connected within the sliding hole 301b. Figures 2 to 5 It can be seen that the upper surface of the mounting block 201c is provided with an elongated sliding hole 301b, and an L-shaped translation rod 301a is slidably connected in the sliding hole 301b. When the mounting block 201c moves, it drives the translation rod 301a to rotate synchronously.

[0050] The leveling component 302 includes two telescopic rods 203a1 and 203a2, which are rotatably connected to the inner sides of the guide section 108 and the grinding section 109. The telescopic rods 203a1 and 203a2 are not on the same horizontal plane. It also includes an auxiliary plate 302c, with the telescopic rods 203a1 and 203a2 rotatably connected to both ends of the auxiliary plate 302c. A counterweight 302d is fixedly connected to the bottom end of the auxiliary plate 302c. Figures 2 to 5 It can be seen that the inner sides of the guide part 108 and the grinding part 109 are rotatably connected to the telescopic plate 302a and the telescopic plate 302b. The auxiliary plate 302c is rotatably connected at the middle position of the telescopic plate 302a and the telescopic plate 302b. When the translation rod 301a moves, it drives the auxiliary plate 302c to move synchronously. At this time, the position of the counterweight 302d moves at the same time, and continuously provides the reverse balance torque during the translation grinding process to ensure the stability of the grinding head 202c when it is working.

[0051] Working principle: As shown in Example 2, the cylinder 201b drives the mounting block 201c to move synchronously. At this time, the mounting block 201c drives the translation rod 301a to move synchronously. When the translation rod 301a moves, it drives the auxiliary plate 302c to move synchronously. At this time, the position of the counterweight 302d moves simultaneously. During the translation and grinding process, it continuously provides a reverse balancing torque to ensure the stability of the grinding head 202c when it is working.
