Description

Technical Field

[0001] The present invention relates to the technical field of wind power detection, and more specifically to a wind power equipment detection device. Background Art

[0002] With the increasing global demand for renewable energy, wind power generation has become one of the important clean energy sources. Wind turbine generators (WTGs) are usually installed on tall poles, which not only support huge wind rotors and generators, but also bear the influence of wind loads, gravity and other environmental factors. Therefore, it is very important to ensure the safety and reliability of wind power equipment poles.

[0003] At present, the inspection of wind power equipment poles mainly relies on manual inspection and some traditional inspection methods. These methods have the following shortcomings: Manual inspection: technicians need to climb to the top of the pole, which is time-consuming, labor-intensive, and inefficient. Climbing to a high place poses a great safety risk, especially in bad weather conditions. Drone inspection: Drones are relatively unstable when flying or inspecting, which can easily lead to unclear collected content and ultimately unclear inspection results.

[0004] Pole-climbing robots: Their applications in wind power equipment inspection are gradually increasing. Pole-climbing robots can crawl along the pole 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, making them not very applicable.

[0005] Therefore, it is necessary to propose a wind power equipment detection device to solve the above problems. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-6 A wind power equipment detection device comprises two symmetrically arranged arc rods 1, which increase the distance between the arc rods 1 and the wind power tower 36, so as to facilitate subsequent installation. The two ends of the arc rods 1 are fixedly connected with straight rods 2, and 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 rod 1, and a compensation mechanism that can always fit the wind power tower 36 is slidably arranged in the middle of the arc rod 1; When the compensation mechanism slides toward the center of the wind power tower 36, it can be self-locked on the arc rod 1 in real time. An unlocking mechanism is provided at the bottom of the arc rod 1, so that the compensation mechanism can move away from the center of the wind power tower 36. The compensation mechanism can drive the rolling climbing mechanism to always fit and move up and down along the wind power tower 36; An annular detection mechanism is arranged on the arc rod 1 .

[0023] Specific, combined Figure 4 As shown, a guide slot 3 with a cross-shaped cross section is provided on the side of the straight rod 2, and a slider 4 is slidably connected in the guide slot 3 to prevent the slider 4 from escaping from the guide slot 3, and both ends of the rolling climbing mechanism are fixedly connected to the slider 4.

[0024] Specific, combined 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 shaft sleeve 9 is fixed in the middle of the cylinder 5 located on one side of the motor 7. When the cylinder 5 is installed, the connecting shaft is used to connect with the output shaft of the motor 7, so that the motor 7 is used to drive the roller 37 to rotate, thereby driving the rubber wheel 13 to move along the wind power tower 36; One end of the cylinder 5 that is rotatably connected to the slider 4 is provided with an external threaded ring 10, and the external threaded ring 10 is threadedly connected to the inner sides of both ends of the roller 37. The cylinder 5 can be disassembled by rotating the external threaded ring 10. In order to achieve the overall balance of the device, a counterweight 6 is provided in the cylinder 5 opposite to the motor 7.

[0025] Specific, combined Figure 1-Figure 4 as well as Figure 6 As shown, the compensation mechanism includes a straight plate 14 slidably connected to the middle of the arc rod 1, a magnetic block 15 rotatably connected to one 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 setting of the straight plate 14 can ensure the stability of the magnetic block 15 when it moves, and it does not swing back and forth in the horizontal plane. Secondly, the rotation setting of the magnetic block 15 is to match the shape of the outer side of the wind turbine tower 36. Some wind turbine towers 36 are conical cylinders, and some are conical cylinders with inconsistent upper and lower tapers. The rotation setting of the magnetic block 15 can adapt to the shapes of the two 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 be self-locked on the arc rod 1 in real time, and an unlocking mechanism is also provided for unlocking the straight plate 14.

[0026] Specific, combined Figure 6 As shown, the straight plate 14 is symmetrically provided with card slots 17 on both sides, and the card slots 17 are zigzag-shaped. The arc-shaped rods 1 on both sides of the straight plate 14 are symmetrically provided with mounting slots 18. The bottom of the mounting slot 18 away from the magnetic block 15 is fixedly connected with a mounting rod 19. The outer side of the mounting rod 19 is rotatably connected with a card rod 20. The end of the card rod 20 away from the straight plate 14 is fixedly connected with a second spring 21. The end of the second spring 21 away from the card rod 20 is fixedly connected to the side of the mounting slot 18. When the compensation mechanism moves toward the center of the wind power tower 36, the second spring 21 can press against the card rod 20 to be stuck in the card slot 17, thereby preventing the straight plate 14 from moving back.

[0027] Specific, combined Figure 3 and Figure 6As shown, the unlocking mechanism includes an electric push rod 22 fixedly connected to the lower end of the arc 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. A through groove 25 connected to the mounting groove 18 is opened at the lower end of the arc rod 1. The round rod 24 passes through the through groove 25 to the mounting groove 18, so that when the electric push rod 22 contracts, it can drive the push plate 23 to move, and then the round rod 24 drives the locking rod 20 to move out of the locking groove 17. When the electric push rod 22 is extended, it can drive the locking rod 20 to fit the locking groove 17 again under the action of the rebound force of the second spring 21.

[0028] Specific, combined Figure 1-4 As shown, a non-elastic drawstring 26 is fixedly connected to the side of the magnetic block 15, the drawstring 26 passes through the straight rod 2 and is fixed on the slider 4 at one end facing the arc rod 1, the slider 4 is fixedly connected to the first spring 11 at one end away from the drawstring 26, and the first spring 11 is fixedly connected to the end of the straight rod 2 away from the arc rod 1 at one end away from the slider 4. In addition, the suction force of the magnetic block 15 must be large enough, at least larger than the pull-back force of the first spring 11 and the force acting on the back of the wind turbine tower 36 generated when the rolling climbing mechanism moves.

[0029] Specific, combined Figure 4 As shown, the end of the straight rod 2 away from the arc rod 1 is threadedly connected with a threaded push rod 12. The purpose of setting the threaded push rod 12 is to adjust the initial position of the slider 4. For example, the device is installed at a position of 1 meter from the bottom of the wind power tower 36. At this time, the position of the threaded push rod 12 is as shown in FIG. Figure 4 If the position shown in the figure is consistent, then when the device as a whole slides down, the device as a whole will still stay in this position. When the threaded top rod 12 is rotated to increase the length of the threaded top rod 12 located in the guide slot 3, the device as a whole will slide down and stay at a position greater than 1 meter at the bottom of the wind tower 36.

[0030] Specific, combined Figure 5As shown, the annular detection mechanism includes a symmetrically arranged semicircular rod 29, an arc-shaped sliding rod 32 rotatably connected to the semicircular rod 29, an air blowing device 35 evenly fixedly connected to the upper end of the semicircular rod 29, and a state acquisition device 34 evenly 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 side of the wind tower 36 to prevent debris from covering the damage to the surface of the wind tower 36. The state acquisition device 34 should at least include a device for monitoring the wind tower 36, such as a visual sensor, which collects images of the pole surface through a camera to detect defects such as cracks and corrosion; an ultrasonic sensor, which detects through an ultrasonic probe Defects inside the measuring rod body; infrared sensor, detects temperature distribution through infrared camera, and finds potential hot spots or overheating areas. The state acquisition device 34 and the blowing device 35 can be selected according to actual conditions, and other functional structures can also be added. A through-type arc-shaped slide groove 30 for installing an arc-shaped slide rod 32 is opened in the middle of the semicircular rod 29. The lower end of the arc-shaped slide groove 30 passes through the lower end surface of the semicircular rod 29, and the lower end of the arc-shaped slide rod 32 is fixedly connected with a push block 33. Through the arrangement of the arc-shaped slide groove 30 and the arc-shaped slide rod 32, the two semicircular rods 29 can be quickly connected, thereby ensuring the overall stability of the annular detection mechanism when the device is moving.

[0031] Specific, combined Figure 1-Figure 3 as well as Figure 5 As shown, a support rod 28 is fixedly connected to one side of the semicircular rod 29 , and a mounting block 27 is rotatably connected to the lower end of the support rod 28 , and the mounting block 27 is fixedly connected to the arc rod 1 .

[0032] During installation, first rotate the support rod 28 so that the semicircular rod 29 is parallel to the arc rod 1 and symmetrically arranged on both sides of the wind tower 36, then align the two ends of the roller 37 with the cylinder 5 and insert it until the limit ring 8 fits the cylinder 5, then rotate the external threaded ring 10 to limit the roller 37 to the outer periphery of the cylinder 5, rotate the arc slide rod 32 and insert it into the arc slide groove 30 on the other side to complete the temporary fixation of the two semicircular rods 29. At this time, under the action of the suction force of the magnetic suction block 15, the pull belt 26 will be pulled, thereby driving the slider 4 to move, so that the slider 4 drives the cylinder 5 to move, and finally the rubber wheel 13 fits the wind tower 36; When in use, by starting the motor 7, the device as a whole is driven to move upward along the wind power tower 36. During the movement, under the action of magnetic attraction, the magnetic block 15 always maintains a certain distance from the wind power tower 36, thereby ensuring that the rubber wheel 13 always fits the wind power tower 36; During the upward movement, the magnetic block 15 will drive the straight plate 14 to move toward the wind power tower 36, and under the action of the elastic force of the second spring 21, the clamping rod 20 will be driven to insert into the clamping slot 17. As the straight plate 14 moves, the clamping rod 20 is inserted into different clamping slots 17 in sequence, thereby preventing the straight plate 14 from moving back. During the upward movement, the blowing device 35 will blow away the debris on the outer side of the wind power tower 36, so as to ensure that the state acquisition device 34 can more accurately acquire the state of the wind power tower 36; During the downward movement, the electric push rod 22 is controlled to retract, so that the electric push rod 22 drives the push plate 23 to move, thereby causing the round rod 24 to push the clamping rod 20 to rotate, so that the clamping rod 20 is moved out of the clamping slot 17, and at the same time, the motor 7 is controlled to reverse, and only the suction force of the magnetic block 15 is used to ensure the stability of the overall sliding of the device. At the same time, before using the device, the threaded top rod 12 is rotated to adjust its length in the guide slot 3, so as to adjust the initial position of the slider 4, and then the distance at which the device stops at the bottom of the wind tower 36 when the device slides down as a whole can be controlled.
