Description

Technical Field

[0001] The present invention provides a photovoltaic panel damage inspection device based on visual recognition, and specifically relates to the technical field of photovoltaic power station inspection equipment. Background Art

[0002] Photovoltaic panel damage inspection device is often used for daily inspections in photovoltaic stations and for recycling damaged photovoltaic panels in photovoltaic stations. It mainly uses drones equipped with inspection components (such as image acquisition cameras, thermal imaging cameras, etc.) to fly above the photovoltaic panels to inspect them and find the damaged or faulty parts of a photovoltaic panel. The damaged photovoltaic panels are then manually dismantled and recycled.

[0003] At present, the recycling of photovoltaic panels mainly involves dismantling them as a whole and then disassembling them (including disassembling of circuit boards, photovoltaic panels, metals and other components). After that, the photovoltaic panels are treated by physical and chemical methods to achieve recycling. However, since the damage to the photovoltaic panels is not integral, overall treatment wastes resources. Large photovoltaic panels need to be disassembled first, and after removing the damaged and faulty parts, the remaining good parts can be recycled, and the damaged parts are then crushed and recycled. However, the current related technology mainly involves disassembling the photovoltaic panels to the factory first, and then testing them one by one to determine the damage points before disassembling them, which makes the efficiency low.

[0004] Although the current photovoltaic panel damage inspection device has the function of detecting photovoltaic panel failures and damaged parts, it does not take into account the fact that during the actual inspection process, photovoltaic panels are installed at an angle, and the angles of inclination of photovoltaic panels in different areas are also different. Therefore, the image acquisition camera and the thermal imaging camera cannot capture the image of the photovoltaic panel well during the image acquisition process, which leads to errors in the image and data collection of the damaged parts of the photovoltaic panel, which is not conducive to accurately obtaining the damaged parts of the photovoltaic panel. At the same time, the existing photovoltaic panel damage inspection device does not have the function of marking the damaged parts in real time during the inspection of photovoltaic panels. On the one hand, when the photovoltaic panels are subsequently dismantled, they cannot be intuitively discovered by the staff. On the other hand, in order to determine the damaged parts of the photovoltaic panels after dismantling, manual inspection with the help of detection equipment is still required. This process is time-consuming and labor-intensive, and the overall efficiency is low. Therefore, the present invention proposes a photovoltaic panel damage inspection device based on visual recognition to make up for and improve the deficiencies of the prior art.

DETAILED DESCRIPTION

[0019] The present invention will be further described below in conjunction with the embodiments.

[0020] Embodiment 1: Figures 1 to 5 As shown, a photovoltaic panel damage inspection device based on visual recognition includes a drone body 1, and a visual camera 11 and a thermal imaging camera 12 are respectively arranged under the drone body 1. Both of them and the drone body 1 are controlled by an external controller. The above are all existing technologies, and their detailed connection relationships and principles are not repeated here.

[0021] An adaptable adjustment mechanism is provided between the bottom of the drone body 1 and the visual camera 11 and the thermal imaging camera 12. The adaptable adjustment mechanism includes a center plate 21 fixedly connected to the bottom of the drone body 1. A semicircular worm gear 22 is fixedly provided at the bottom center of the center plate 21. Two semicircular discs 23 are also symmetrically fixedly provided at the bottom of the center plate 21. The two semicircular discs 23 are symmetrically located on both sides of the semicircular worm gear 22. Semicircular grooves 24 are provided on the outer annular surfaces of the two semicircular discs 23. A cross plate 27 is slidably provided inside the two semicircular grooves 24. The semicircular discs 23, the semicircular grooves 24 and the semicircular worm gear 22 are all concentrically arranged. The center plate 21 is located at the center position of the bottom of the drone body 1, ensuring that all components on the center plate 21 are relatively located near the center position of the drone body 1 to maintain the stability of the overall center of gravity of the drone body 1. The cross plate 27 is initially in a horizontal state. The visual camera 11 and the thermal imaging camera 12 are symmetrically located below the drone body 1, and the two are fixedly installed on both sides of the bottom of the cross plate 27. A T-shaped block is provided at the position where the cross plate 27 slides with the semi-circular groove 24, and the T-shaped block is slidably connected to the inside of the semi-circular groove 24. The shape of the semi-circular groove 24 is adapted to the shape of the T-shaped block, and its function is that the T-shaped block will not separate from the semi-circular groove 24 when sliding and displacing inside the semi-circular groove 24. A stepper motor 25 is fixedly installed on the upper surface of the cross plate 27 away from the semicircular worm gear 22, and a detection sensor 251 is fixedly installed on the bottom of the cross plate 27. The detection sensor 251 can detect the angle and is started and closed by an external controller. At the same time, the detection sensor 251 is electrically connected to the controller on the stepper motor 25. A worm 26 is fixedly connected to the output shaft of the stepper motor 25 on the side close to the semicircular worm gear 22, and one end of the worm 26 away from the stepper motor 25 is rotatably connected to the upper surface of the cross plate 27. The worm 26 and the semicircular worm gear 22 are meshed with each other.

[0022] During use: the staff starts the drone body 1 through the external controller, prompting the drone body 1 to drive the visual camera 11 and the thermal imaging camera 12 to fly above the photovoltaic panel that needs to be inspected, and then starts the visual camera 11, the thermal imaging camera 12 and the detection sensor 251 at the same time through the controller. After the detection sensor 251 is started, it will automatically detect the inclination angle of the photovoltaic panel, and transmit the detected inclination angle signal to the controller on the stepper motor 25 and start the stepper motor 25. After the stepper motor 25 is started, it will drive the worm 26 to rotate a fixed angle through its output shaft. The semicircular worm wheel 22 is meshed with the worm 26, and the semicircular worm wheel 22 is fixed at the bottom of the center plate 21. At this time, as the worm 26 rotates, the cross plate 27 will be prompted to rotate synchronously with the semi-annular groove 24 as the trajectory, thereby prompting the stepper motor 25, the visual camera 11 and the thermal imaging camera 12 to rotate synchronously, thereby realizing the angle adjustment of the visual camera 11 and the thermal imaging camera 12, until the visual camera 11 and the thermal imaging camera 12 are vertically facing the surface of the photovoltaic panel, the stepper motor 25 stops and remains in the current state, and the self-locking property between the worm 26 and the semicircular worm wheel 22 is used to ensure stability after rotation. After the angle adjustment of the visual camera 11 and the thermal imaging camera 12 is completed, as the drone body 1 flies above the photovoltaic panel, all photovoltaic panels can be inspected.

[0023] Therefore, through the adaptive adjustment mechanism, when the drone body 1 flies above the photovoltaic panel, the shooting and collection angles of the visual camera 11 and the thermal imaging camera 12 are automatically and flexibly adjusted according to the inclination angle of the photovoltaic panel to ensure that the two are always stably and vertically facing the photovoltaic panel, thereby ensuring that detailed images and data of the surface of the photovoltaic panel can be captured and photographed, which is conducive to obtaining the accurate damage location of the photovoltaic panel.

[0024] Embodiment 2: Figures 1 to 3 as well as Figures 6 to 11As shown, the above-mentioned photovoltaic panel damage inspection device based on visual recognition also includes a detection mark mechanism provided on one side of the cross plate 27, the detection mark mechanism includes a concave plate 31 fixedly connected to one side of the cross plate 27, and the concave plate 31 is located at the bottom of the cross plate 27, and an electric telescopic rod 32 is fixedly installed on the side of the concave plate 31 away from the cross plate 27, and the electric telescopic rod 32 is started and closed by an external controller. A slotted plate 33 is fixedly connected to the telescopic end of the electric telescopic rod 32, and a spring telescopic rod 34 is slidably connected inside the slotted plate 33. The spring telescopic rod 34 is composed of an external sleeve rod and an inner rod slidably sleeved inside the sleeve rod, and a built-in spring is connected between the inner rod and the inner wall of the sleeve rod. A pressure block 342 is fixedly connected to the outer wall of one side of the top of the spring telescopic rod 34. An inclined surface is provided on one side of the pressure block 342. A stopper 343 is fixedly connected to the bottom of the concave plate 31 near the pressure block 342. The stopper 343 is located on the path of the downward movement of the inclined surface of the pressure block 342. After the pressure block 342 moves downward to the final position, its inclined surface always contacts the outer wall of the stopper 343. A limiting groove is provided on the groove plate 33 for the horizontal displacement of the spring telescopic rod 34. The top of the spring telescopic rod 34 is T-shaped, and slides in the limiting groove through the T-shaped portion. A horizontal spring 341 is connected between the top of the spring telescopic rod 34 and the inner wall of the slotted plate 33, and a cam fixed box 35 is fixedly connected to the telescopic end below the spring telescopic rod 34. A cam movable box 36 is tightly inserted into the side of the cam fixed box 35 away from the spring telescopic rod 34, and the cam movable box 36 and the cam fixed box 35 are interference connected. A triangular block 361 is fixedly arranged at the bottom of the cam movable box 36, and the inner walls of the cam fixed box 35 are rotatably connected with shaft one 39 and shaft two 391 respectively, and shaft one 39 is located above shaft two 391, and one end of shaft one 39 close to the inner wall of the cam fixed box 35 is fixedly connected with a large gear 310, and the large gear 310 and the inner wall of the cam fixed box 35 are in contact with each other, and the contact surfaces of the two are both frosted surfaces. Under the action of the friction between the two, it is ensured that the large gear 310 will not rotate when no force is applied. The end of the second shaft 391 close to the inner wall of the cam box 35 is fixedly connected with a small gear 311, and the small gear 311 meshes with the large gear 310. A marking tape 312 is wound around the outer ring surface of the first shaft 39. The marking tape 312 is mainly composed of a release paper and a resin adhesive coated on the outer surface of the release paper, specifically a dot-shaped double-sided adhesive. The cam box 35 and the cam moving box 36 are both made of transparent acrylic material, and a handle is provided on the side of the cam moving box 36 away from the cam box 35. The transparent material allows users to intuitively see the use of the internal marking tape 312, and the handle allows users to pinch the cam moving box 36 with their hands to separate the cam box 35 from the cam box 35. The end of the marking tape 312 away from the first shaft 39 passes through the bottom of the cam moving box 36 and bypasses the outer surface of the triangular block 361, and is finally bonded to the outer ring surface of the second shaft 391. Specifically, the free end of the marking tape 312 close to the first shaft 39 is bonded to the outer ring surface of the first shaft 39 by an adhesive tape.Two through holes are provided at the bottom of the cam movable box 36 for the marking tape 312 to pass through. The free end of the marking tape 312 on the side away from the axis 1 39 extends to the outside of the cam movable box 36 through one through hole, and then passes through the other through hole to enter the inside of the cam fixed box 35. The free end of the marking tape 312 on the side away from the axis 1 39 is also adhered to the outer ring surface of the axis 2 391 by tape; and the part of the marking tape 312 that bypasses the outer surface of the triangular block 361 is tightly fitted with the outer surface of the triangular block 361, and the bottom of the triangular block 361 is provided with rounded corners. The function of the rounded corners is to prevent the marking tape 312 from being cut.

[0025] Furthermore, if Figure 6 , Figure 7 As shown, a small air pump 37 is fixedly mounted on one side of the outer wall of the top of the cam fixing box 35, and the small air pump 37 is started and closed by an external controller. A cavity plate 38 is connected to the air outlet end below the small air pump 37, and the side of the cavity plate 38 away from the small air pump 37 is flared, and the flared part faces the direction of the horizontal movement of the triangular block 361.

[0026] When in use: since the detection mark mechanism is arranged on the cross plate 27, as the cross plate 27 rotates, the detection mark mechanism will also adjust its angle synchronously.

[0027] When the thermal imaging camera 12 detects a damaged part on a photovoltaic panel, the drone body 1 is controlled to fly through an external controller so that the triangular block 361 is aligned with the damaged part of the photovoltaic panel. When the electric telescopic rod 32 and the small air pump 37 are started, the telescopic end of the electric telescopic rod 32 will drive the grooved plate 33, the spring telescopic rod 34 and the related parts on the cam fixed box 35 to move downward gradually. When the part of the marking band 312 that is tightly fitted on the outer surface of the triangular block 361 contacts the surface of the photovoltaic panel, the inclined surface of the pressing block 342 just presses against the outer surface of the push rod 343, and the telescopic end of the electric telescopic rod 32 has not yet extended to the final position. As the telescopic end of the electric telescopic rod 32 continues to move downward, the inclined surface will continue to squeeze the outer surface of the push rod 343, and then under the guidance of the inclined surface, the spring telescopic rod 34 will be horizontally displaced along the trajectory of the limit groove, and the horizontal spring 341 will be continuously compressed during the process. When the telescopic end of the electric telescopic rod 32 is extended to the final position, the spring telescopic rod 34 also slides and displaces to the final position. As the spring telescopic rod 34 moves horizontally, the part of the marking tape 312 located at the position of the triangular block 361 will be synchronously translated along the surface of the photovoltaic panel. During the process, under the friction between the marking tape 312 and the photovoltaic panel, the part of the marking tape 312 wound around the surface of the shaft 1 39 will be released and drive the large gear 310 to rotate. After the large gear 310 rotates, it will drive the small gear 311 to rotate in the opposite direction. As the small gear 311 rotates, the used part of the marking tape 312 will be automatically wound around the outer ring surface of the shaft 2 391. In this way, as the marking tape 312 at the triangular block 361 moves along the surface of the photovoltaic panel, a white mark will be made on the surface of the photovoltaic panel. The white mark can form a sharp contrast with the gray-black photovoltaic panel, so that the staff can intuitively see the damaged part.

[0028] As the telescopic end of the electric telescopic rod 32 continues to move downward, driving the pressure block 342 to squeeze the support rod 343, the telescopic end of the spring telescopic rod 34 will also be automatically contracted. Therefore, under the elastic force of the spring telescopic rod 34, the marking tape 312 at the triangular block 361 is always in close contact with the surface of the damaged part of the photovoltaic panel, ensuring that the white mark can be coated on the surface of the photovoltaic panel.

[0029] In the above process, after the small air pump 37 is started, the airflow will be continuously blown out through the cavity plate 38, so that the blown airflow is blown to the surface of the damaged part of the photovoltaic panel. Therefore, the small air pump 37 and the cavity plate 38 are used to continuously blow out the airflow to blow the damaged part of the photovoltaic panel, so as to blow away the dust and impurities attached to the damaged part of the photovoltaic panel, ensuring that the marking tape 312 can make an effective mark on the damaged part of the photovoltaic panel.

[0030] Therefore, by setting up a detection and marking mechanism, using the cooperation of components such as the triangular block 361 and the marking tape 312, when a damaged part of the photovoltaic panel is detected, a white mark will be automatically made on the damaged part to clearly mark the location of the damaged part, thereby facilitating the staff to directly find the damaged photovoltaic panel after subsequent disassembly of the photovoltaic panel. At the same time, there is no need for the staff to manually detect the damaged part of the photovoltaic panel again, thereby saving a lot of time, improving the overall operating efficiency of the photovoltaic panel recycling link, and facilitating the subsequent processing of the photovoltaic panel.

[0031] At the same time, after each marking, the used marking tape 312 will be retracted to the shaft 2 391 inside the cam box 36, and the unused marking tape 312 will be released, so as to facilitate the continuous and stable white marking during the flight inspection of the drone body 1, thereby ensuring the continuity of the marking operation of the damaged parts of the photovoltaic panel.

[0032] When the drone body 1 is retracted after each flight inspection, the staff can visually see the use of the internal marking tape 312 through the cam fixed box 35 and the cam movable box 36. If a new marking tape 312 needs to be replaced, the staff can manually separate the cam movable box 36 from the cam fixed box 35, and then remove the used marking tape 312 from the second shaft 391. When installing again, first adhere one free end of the marking tape 312 to the outer wall of the first shaft 39, then gradually wrap the marking tape 312 around the outer wall of the first shaft 39, and then pass the other free end of the marking tape 312 through a through hole on the cam fixed box 35, and then fit with the outer wall of the triangular block 361, so that the other through hole passes back to the inside of the cam movable box 36, and finally adhere the free end to the outer wall of the second shaft 391, so that the replacement of the marking tape 312 is completed.

[0033] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. Such modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
