Description

Technical Field

[0001] This invention relates to the field of wind power testing technology, and more specifically to a wind power equipment testing device. Background Technology

[0002] With the increasing global demand for renewable energy, wind power has become one of the important clean energy sources. Wind turbine generators (WTGs) are typically mounted on tall masts that not only support the massive rotor and generator but also withstand wind loads, gravity, and other environmental factors. Therefore, ensuring the safety and reliability of the wind turbine masts is crucial.

[0003] Currently, the inspection of wind turbine poles mainly relies on manual inspections and some traditional testing methods. These methods have the following shortcomings:

[0004] Manual inspection: This requires technicians to climb to the top of the pole, which is time-consuming, labor-intensive, and inefficient. Climbing to high places also poses significant safety risks, especially in adverse weather conditions.

[0005] Drone inspection: Drones are relatively unstable during flight or inspection, which can easily lead to unclear data collection and ultimately unclear inspection results.

[0006] Pole-climbing robots are increasingly used in the inspection of wind power equipment. They can climb along poles autonomously or remotely to perform inspection tasks. However, existing pole-climbing robots have poor adaptability to poles of different shapes and diameters and need to be customized for different types of poles, resulting in limited applicability.

[0007] Therefore, it is necessary to propose a wind power equipment testing device to solve the above problems. Summary of the Invention

[0008] The purpose of this invention is to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0010] A wind power equipment testing device includes two symmetrically arranged arc-shaped rods, with straight rods fixedly connected to both ends of the arc-shaped rods. A rolling climbing mechanism that can move up and down along the wind turbine tower is slidably arranged between the straight rods at the ends of each arc-shaped rod. A compensation mechanism that can always fit against the wind turbine tower is slidably arranged in the middle of the arc-shaped rod.

[0011] When the compensation mechanism slides toward the center of the wind turbine tower, it can self-lock onto the arc-shaped rod in real time. The bottom of the arc-shaped rod is equipped with an unlocking mechanism so that the compensation mechanism moves away from the center of the wind turbine tower. The compensation mechanism can drive the rolling climbing mechanism to always stay close to and move up and down along the wind turbine tower.

[0012] The arc-shaped rod is equipped with a ring-shaped detection mechanism;

[0013] The straight rod has a guide groove on its side, and a slider is slidably connected in the guide groove. The two ends of the rolling climbing mechanism are respectively fixedly connected to the sliders of the opposite straight rod.

[0014] The rolling climbing mechanism includes a cylinder fixedly connected to the slider, a roller rotatably connected to the outer side of the cylinder, a rubber wheel fixedly connected to the middle of the outer side of the roller, and a motor fixed in one of the cylinders, the motor being used to drive the roller to rotate;

[0015] The cylinder is rotatably connected to an external threaded ring at one end facing the slider. The external threaded ring is threaded to the inner sides of both ends of the drum. A counterweight is provided in the cylinder opposite to the motor.

[0016] Furthermore, the compensation mechanism includes a straight plate slidably connected to the middle of the arc-shaped rod, a magnetic block rotatably connected to the end of the straight plate facing the wind turbine tower, and rollers symmetrically rotatably connected to the upper and lower ends of the magnetic block. When the compensation mechanism moves toward the center of the wind turbine tower, the straight plate can self-lock onto the arc-shaped rod in real time, and the unlocking mechanism is used to unlock the straight plate.

[0017] Furthermore, the straight plate has symmetrical slots on both sides, and the arc-shaped rods on both sides of the straight plate have symmetrical mounting slots. The bottom of the mounting slot away from the magnetic block is fixedly connected to a mounting rod, and the outer side of the mounting rod is rotatably connected to a locking rod. The end of the locking rod away from the straight plate is fixedly connected to a second spring, and the end of the second spring away from the locking rod is fixedly connected to the side of the mounting slot. When the compensation mechanism moves toward the center of the wind turbine tower, the second spring can abut against the locking rod and engage in the slot.

[0018] Furthermore, the unlocking mechanism includes an electric push rod fixedly connected to the lower end of the arc-shaped rod, a push plate fixedly connected to the output end of the electric push rod, and a round rod fixedly connected to the end of the push plate. The lower end of the arc-shaped rod is provided with a through groove communicating with the mounting groove. The round rod passes through the through groove into the mounting groove, so that when the electric push rod drives the push plate to move, the round rod drives the locking rod to move out of the locking groove.

[0019] Furthermore, a pull strap is fixedly connected to the side of the magnetic block. The pull strap passes through the straight rod and is fixed to the slider at one end facing the arc-shaped rod. A first spring is fixedly connected to the end of the slider away from the pull strap. The end of the first spring away from the slider is fixedly connected to the end of the straight rod away from the arc-shaped rod.

[0020] Furthermore, the end of the straight rod away from the curved rod is threadedly connected to a threaded push rod.

[0021] Furthermore, the annular detection mechanism includes symmetrically arranged semi-circular rods, an arc-shaped slide rod rotatably connected in the semi-circular rods, an air blowing device uniformly fixedly connected to the upper end of the semi-circular rods, and a status acquisition device uniformly fixed to the inner side of the arc-shaped slide rods. The semi-circular rods have a through arc-shaped groove in the middle for installing the arc-shaped slide rods. The lower end of the arc-shaped groove penetrates the lower end face of the semi-circular rods. A push block is fixedly connected to the lower end of the arc-shaped slide rods.

[0022] Furthermore, a support rod is fixedly connected to one side of the semi-circular rod, and a mounting block is rotatably connected to the lower end of the support rod, the mounting block being fixedly connected to the arc-shaped rod.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] 1. The present invention, through the setting of the compensation mechanism, enables the rolling climbing mechanism to always fit the wind turbine tower, thereby adapting to wind turbine towers of different diameters.

[0025] 2. In this invention, by setting an unlocking mechanism, under the setting of a compensation mechanism, when the rolling climbing mechanism moves upward, the compensation mechanism can achieve self-locking, thus preventing it from sliding down when moving upward.

[0026] 3. The present invention, through the combination of a semi-circular rod and an arc-shaped sliding rod, can achieve temporary fixation of two semi-circular rods.

[0027] 4. The present invention enables the disassembly of the roller through the matching arrangement between the roller and the external threaded ring, thereby facilitating the removal and installation of the detection device from the wind turbine tower. Attached Figure Description

[0035] 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 embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Please see Figure 1-6 A wind power equipment testing device includes two symmetrically arranged arc-shaped rods 1, which increase the distance between the arc-shaped rods 1 and the wind power tower 36 to facilitate subsequent installation. Straight rods 2 are fixedly connected to both ends of the arc-shaped rods 1. A rolling climbing mechanism that can move up and down along the wind power tower 36 is slidably arranged between the straight rods 2 at the ends of each side of the arc-shaped rods 1. A compensation mechanism that can always fit against the wind power tower 36 is slidably arranged in the middle of the arc-shaped rods 1.

[0037] When the compensation mechanism slides toward the center of the wind turbine tower 36, it can lock itself onto the arc-shaped rod 1 in real time. The bottom of the arc-shaped rod 1 is equipped with an unlocking mechanism so that the compensation mechanism can move away from the center of the wind turbine tower 36. The compensation mechanism can drive the rolling climbing mechanism to always adhere to and move up and down along the wind turbine tower 36.

[0038] A ring-shaped detection mechanism is installed on the arc-shaped rod 1.

[0039] Specifically, in combination Figure 4 As shown, the straight rod 2 has a cross-shaped guide groove 3 on its side. A slider 4 is slidably connected in the guide groove 3, which can prevent the slider 4 from falling out of the guide groove 3. The two ends of the rolling climbing mechanism are fixedly connected to the slider 4.

[0040] Specifically, in combination Figure 4As shown, the rolling climbing mechanism includes a cylinder 5 fixedly connected to the slider 4, a roller 37 rotatably connected to the outer side of the cylinder 5, a rubber wheel 13 fixedly connected to the middle of the outer side of the roller 37, and a motor 7 fixed in one of the cylinders 5. A bushing 9 is fixed in the middle of the cylinder 5 located on one side of the motor 7. When the cylinder 5 is installed, it is used as a connecting shaft to the output shaft of the motor 7, so that the motor 7 can drive the roller 37 to rotate, thereby driving the rubber wheel 13 to move along the wind turbine tower 36.

[0041] The cylinder 5 is rotatably connected to an external threaded ring 10 at one end facing the slider 4. The external threaded ring 10 is threaded to the inner sides of both ends of the roller 37. By rotating the external threaded ring 10, the cylinder 5 can be disassembled. In order to achieve the overall balance of the device, a counterweight 6 is provided in the cylinder 5 opposite to the motor 7.

[0042] Specifically, in combination Figures 1-4 as well as Figure 6 As shown, the compensation mechanism includes a straight plate 14 slidably connected to the middle of the arc-shaped rod 1, a magnetic block 15 rotatably connected to the end of the straight plate 14 facing the wind turbine tower 36, and rollers 16 symmetrically rotatably connected to the upper and lower ends of the magnetic block 15. The straight plate 14 ensures the stability of the magnetic block 15 during movement, preventing it from swinging back and forth on the horizontal plane. Furthermore, the rotation of the magnetic block 15 is designed to match the shape of the outer side of the wind turbine tower 36. Some wind turbine towers 36 are conical cylinders, while others are conical cylinders with inconsistent upper and lower tapers. The rotation of the magnetic block 15 can adapt to the shapes of both types of wind turbine towers 36. When the compensation mechanism moves toward the center of the wind turbine tower 36, the straight plate 14 can self-lock onto the arc-shaped rod 1 in real time. An unlocking mechanism is also provided to unlock the straight plate 14.

[0043] Specifically, in combination Figure 6 As shown, the straight plate 14 has symmetrical slots 17 on both sides. The slots 17 are serrated. The arc rods 1 on both sides of the straight plate 14 have symmetrical mounting slots 18. The bottom of the mounting slot 18 away from the magnetic block 15 is fixedly connected to the mounting rod 19. The outer side of the mounting rod 19 is rotatably connected to the locking rod 20. The end of the locking rod 20 away from the straight plate 14 is fixedly connected to the second spring 21. The end of the second spring 21 away from the locking rod 20 is fixedly connected to the side of the mounting slot 18. When the compensation mechanism moves toward the center of the wind turbine tower 36, the second spring 21 can abut against the locking rod 20 and be locked into the slot 17, thereby preventing the straight plate 14 from moving back.

[0044] Specifically, in combination Figure 3 and Figure 6As shown, the unlocking mechanism includes an electric push rod 22 fixedly connected to the lower end of the arc-shaped rod 1, a push plate 23 fixedly connected to the output end of the electric push rod 22, and a round rod 24 fixedly connected to the end of the push plate 23. The lower end of the arc-shaped rod 1 has a through groove 25 communicating with the mounting groove 18. The round rod 24 passes through the through groove 25 into the mounting groove 18 so that when the electric push rod 22 retracts, it can drive the push plate 23 to move, thereby causing the round rod 24 to drive the locking rod 20 to move out of the locking groove 17. When the electric push rod 22 extends, under the action of the rebound force of the second spring 21, it can drive the locking rod 20 to re-fit into the locking groove 17.

[0045] Specifically, in combination Figure 1-4 As shown, the side of the magnetic block 15 is fixedly connected to a non-elastic pull strap 26. The pull strap 26 passes through the straight rod 2 and is fixed to the slider 4 at one end facing the arc rod 1. The end of the slider 4 away from the pull strap 26 is fixedly connected to a first spring 11. The end of the first spring 11 away from the slider 4 is fixedly connected to the end of the straight rod 2 away from the arc rod 1. In addition, the attraction force of the magnetic block 15 must be large enough to be at least greater than the pull force of the first spring 11 and the force generated by the rolling climbing mechanism moving away from the wind turbine tower 36.

[0046] Specifically, in combination Figure 4 As shown, the end of the straight rod 2 furthest from the curved rod 1 is threadedly connected to a threaded push rod 12. The purpose of the threaded push rod 12 is to adjust the initial position of the slider 4. For example, if this device is installed 1 meter from the bottom of the wind turbine tower 36, the position of the threaded push rod 12 is as follows: Figure 4 If the position shown is consistent, then when the device slides down as a whole, the device will still stay at that position. When the threaded top rod 12 is rotated to increase the length of the threaded top rod 12 located in the guide groove 3, the device will stay at a position more than 1 meter above the bottom of the wind turbine tower 36 when it slides down as a whole.

[0047] Specifically, in combination Figure 5As shown, the ring-shaped detection mechanism includes symmetrically arranged semi-circular rods 29, an arc-shaped sliding rod 32 rotatably connected in the semi-circular rods 29, an air blowing device 35 uniformly fixed to the upper end of the semi-circular rods 29, and a status acquisition device 34 uniformly fixed to the inner side of the arc-shaped sliding rod 32. The air blowing device 35 mainly uses a micro air pump to clean the outer surface of the wind turbine tower 36 to prevent debris from covering the damage on the surface of the wind turbine tower 36. The status acquisition device 34 should at least include a device for monitoring the wind turbine tower 36, such as a visual sensor that uses a camera to collect images of the tower surface to detect defects such as cracks and corrosion; and an ultrasonic sensor that uses an ultrasonic probe to detect... Defects inside the measuring rod body; infrared sensor, through infrared camera to detect temperature distribution, to find potential hot spots or overheated areas. The status acquisition device 34 and the air blowing device 35 can be omitted according to the actual situation, and other functional structures can also be added. The semi-circular rod 29 has a through arc-shaped groove 30 for installing the arc-shaped slide rod 32 in the middle. The lower end of the arc-shaped groove 30 passes through the lower end face of the semi-circular rod 29. The lower end of the arc-shaped slide rod 32 is fixedly connected to the push block 33. Through the setting of the arc-shaped groove 30 and the arc-shaped slide rod 32, the two semi-circular rods 29 can be quickly connected, thereby ensuring the overall stability of the ring detection mechanism when the device moves.

[0048] Specifically, in combination Figures 1-3 as well as Figure 5 As shown, a support rod 28 is fixedly connected to one side of the semi-circular rod 29, and a mounting block 27 is rotatably connected to the lower end of the support rod 28. The mounting block 27 is fixedly connected to the arc-shaped rod 1.

[0049] During installation, first rotate the support rod 28 so that the semi-circular rod 29 is parallel to the arc rod 1 and symmetrically arranged on both sides of the wind turbine tower 36. Then, align the two ends of the roller 37 with the cylinder 5 and insert it until the limiting ring 8 fits against the cylinder 5. Then, rotate the external threaded ring 10 to restrict the roller 37 to the outer circumference of the cylinder 5. Rotate the arc sliding rod 32 and insert it into the arc sliding groove 30 on the other side to complete the temporary fixation of the two semi-circular rods 29. At this time, under the attraction of the magnetic block 15, the pull belt 26 will be pulled, which will drive the slider 4 to move, so that the slider 4 drives the cylinder 5 to move, and finally the rubber wheel 13 fits against the wind turbine tower 36.

[0050] When in use, the motor 7 is started to drive the entire device to move upward along the wind turbine tower 36. During the movement, under the action of magnetic attraction, the magnetic block 15 always maintains a certain distance from the wind turbine tower 36, thereby ensuring that the rubber wheel 13 always fits against the wind turbine tower 36.

[0051] During the upward movement, the magnetic block 15 will drive the straight plate 14 to move toward the wind turbine tower 36. Under the action of the second spring 21, the clamping rod 20 will be inserted into the slot 17. As the straight plate 14 moves, the clamping rod 20 will be inserted into different slots 17 in sequence, thereby preventing the straight plate 14 from moving back.

[0052] During the upward movement, the blowing device 35 will blow away the debris on the outer side of the wind turbine tower 36, thereby ensuring that the status acquisition device 34 can more accurately acquire the status of the wind turbine tower 36.

[0053] During the downward movement, the electric push rod 22 is retracted, causing the electric push rod 22 to drive the push plate 23 to move, thereby causing the round rod 24 to push the locking rod 20 to rotate, so that the locking rod 20 is moved out of the locking groove 17. At the same time, the motor 7 is reversed, and only the attraction force of the magnetic block 15 is used to ensure the stability of the overall downward movement of the device. Before using the device, the threaded top rod 12 is rotated to adjust its length in the guide groove 3, which can adjust the initial position of the slider 4, thereby controlling the distance at which the device stops at the bottom of the wind turbine tower 36 when it slides down.

[0054] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. The scope of patent protection of the present invention shall be determined by the claims. Similarly, any equivalent structural changes made based on the description and drawings of the present invention shall also be included within the scope of protection of the present invention.
