Technical Field

[0001] The invention belongs to the technical field of photovoltaic panel fault detection, and in particular relates to a photovoltaic panel fault detection device for a photovoltaic power station. Background Art

[0002] As a clean and renewable energy device, photovoltaic panels have significant environmental and economic benefits. The power generation process does not produce pollutants and greenhouse gas emissions, which helps reduce dependence on fossil energy, promote the optimization and upgrading of energy structure, and promote sustainable development. At the same time, with the advancement of technology and the reduction of costs, the power generation cost of photovoltaic panels has gradually decreased, and the market competitiveness has continued to improve, providing strong support for energy transformation and green development. The working principle of photovoltaic panels is based on the photovoltaic effect. When sunlight shines on the semiconductor PN junction, the PN junction barrier region generates a strong built-in electrostatic field, which makes the non-equilibrium electrons and holes move in opposite directions under the action of the built-in electrostatic field, thereby generating voltage and current. Multiple solar cell units are connected in series or parallel to increase the output voltage or current to meet the actual application needs; There are multiple photovoltaic panels in a photovoltaic power station. When the photovoltaic panels are actually working, they are easily damaged due to some outdoor accidents. Therefore, cameras are placed at suitable locations to photograph the outer surface of the photovoltaic panels, and then the pictures are transmitted to the comparison module in the control box. The photos of the photovoltaic panels are compared with the photos of the photovoltaic panels prepared in advance. If cracks or gaps are found on the outer surface of the photovoltaic panels, the information will be uploaded to the background management system for the staff to review.

DETAILED DESCRIPTION

[0020] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figure 1-9 As shown, a photovoltaic panel fault detection device of a photovoltaic power station of the present invention comprises a photovoltaic panel 1, which is electrically connected to a control box 101, a support frame 11 is arranged at the rear side of the photovoltaic panel 1, a comparison module is arranged in the control box 101, the outer surface of the photovoltaic panel 1 is wrapped with a mounting frame 12 with an opening upward, a camera 121 connected to the control box 101 is arranged at the lower side of the mounting frame 12, slide grooves 13 are arranged on the left and right sides of the mounting frame 12, a sliding frame 14 is slidably mounted between the two sliding grooves 13, a fixing rod 15 is arranged between the sliding frames 14, a cleaning wheel 16 abutting against the outer surface of the photovoltaic panel 1 is rotatably connected to the outer surface of the fixing rod 15, a placement groove 17 is arranged on the upper and lower sides of the mounting frame 12, a rebound mechanism is arranged between the cleaning wheel 16 and the fixing rod 15, a limiting mechanism is arranged between the sliding frame 14 and the cleaning wheel 16, the placement groove 17 located at the lower side is provided with a cleaning mechanism matching the cleaning wheel 16, and a discharge port 18 is arranged at the lower side of the mounting frame 12.

[0022] When it is necessary to take pictures and compare the outer surface of the photovoltaic panel 1 before detecting a fault, the driving slide frame 14 drives the cleaning wheel 16 from the upper side of the mounting frame 12 to move downward from the upper side of the photovoltaic panel 1. At the same time, since a limiting mechanism is installed between the sliding frame 14 and the cleaning wheel 16, when the cleaning wheel 16 moves downward on the outer surface of the photovoltaic panel 1, the limiting mechanism starts to work to limit the cleaning wheel 16 to prevent the cleaning wheel 16 from rotating. Therefore, during the process of the cleaning wheel 16 moving downward while the photovoltaic panel 1 is moving, the cleaning wheel 16 is in a stationary state, and one side surface of the cleaning wheel 16 is in static friction with the photovoltaic panel 1. During the continuous downward movement of the sliding frame 14, the limiting mechanism stops working intermittently. During the time when the limiting mechanism stops working, the cleaning wheel 16 is taken. The limit of the cleaning wheel 16 is eliminated. Since the cleaning wheel 16 abuts against the surface of the photovoltaic panel 1, the sliding frame 11 drives the cleaning wheel 16 to start rolling during the movement. When the contact surface between the cleaning wheel 16 and the outer surface of the photovoltaic panel 1 is replaced, the cleaning wheel 16 rubs against the photovoltaic panel 1 again. With this design, the cleaning wheel 16 continuously replaces the contact surface between the cleaning wheel 16 and the photovoltaic panel 1 during the downward movement of the outer surface of the photovoltaic panel 1. This design can prevent the cleaning wheel 16 from having only one side surface in contact with the photovoltaic panel 1. When the surface of one side of the cleaning wheel 16 is contaminated, it will affect the cleaning effect of the photovoltaic panel 1. The design of continuously replacing the contact surface between the cleaning wheel 16 and the photovoltaic panel 1 can improve the cleaning effect of the photovoltaic panel 1. When the sliding frame 14 moves downward and the limiting mechanism cancels the limiting gap time of the cleaning wheel 16, the cleaning wheel 16 starts to rotate, and at this time, the rebound mechanism can be driven to start compressing. Each time the limiting mechanism cancels the limiting time of the cleaning wheel 16, the rebound mechanism will be further compressed during the rotation of the cleaning wheel 16. When the sliding frame 14 drives the cleaning wheel 16 to move to the placement groove 17 position on the lower side of the installation frame 12, the limiting mechanism simultaneously cancels the limiting of the cleaning wheel 16. At this time, since the surface of the cleaning wheel 16 does not contact the outer surface of the photovoltaic panel 1, the rebound mechanism starts to extend, and drives the cleaning wheel 16 to rotate and reset at a high speed. At the same time, the cleaning mechanism starts to work and sprays water on the surface of the high-speed rotating cleaning wheel 16, so that the outer surface of the cleaning wheel 16 can be cleaned, and the sewage and impurities scraped off by the cleaning wheel 16 are The cleaning wheel 16 is then displaced back and forth to the top of the cleaning wheel 16, and the cleaning wheel 16 is then displaced back and forth to the top of the cleaning wheel 16. ... After the photovoltaic panel 1 is cleaned, the camera 121 can take pictures of the outer surface of the photovoltaic panel 1 and transmit the pictures to the comparison module of the control box 101. The existing pictures are compared with the original pictures through the comparison module. If there are cracks or gaps on the outer surface of the photovoltaic panel 1 at the comparison point, the control box 101 will transmit the information to the background management system and alarm the staff for the staff to check.

[0023] The limiting mechanism includes a mounting block 2 connected to a sliding frame 14, a groove 21 extending into the mounting block 2 is provided on the side of the sliding frame 14 facing the cleaning wheel 16, an arc-shaped clamp 22 matching the cleaning wheel 16 is slidably mounted in the groove 21, an inner cavity 23 is provided on the left and right sides of the mounting block 2, sliders 24 are slidably mounted in the two inner cavities 23, the two sliders 24 are provided with a sliding rod 25 that slides into the groove 21 and is connected to the arc-shaped clamp 22, the two sliders 24 are provided with a first spring 26 on the side away from the sliding rod 25, and a pulling component connected to the slider 24 on the same side is provided on the left and right sides of the sliding frame 14.

[0024] When the cleaning wheel 16 moves downward on the photovoltaic panel 1, the first spring 26 pushes the slider 24 under the action of the extension of the first spring 26, and the slider 24 drives the arc-shaped clamping member 22 to closely contact the outer surface of the cleaning wheel 16 through the slide rod 25, and the outer surface of the cleaning wheel 16 is clamped and limited by the arc-shaped clamping member 22, which can effectively prevent the cleaning wheel 16 from rotating. When the pulling component is working, it drives the slider 24 to move upward in the inner cavity 23, and the first spring 26 is in a compressed state. The slider 24 drives the arc-shaped clamping member 22 away from the cleaning wheel 16 through the slide rod 25, thereby canceling the limitation of the cleaning wheel 16. When the pulling component stops working, the pulling of the slider 24 is canceled, and then under the action of the extension of the first spring 26, the slider 24 is pushed again, and the arc-shaped clamping member 22 is driven by the slide rod 25 to clamp the outer surface of the cleaning wheel 16 again.

[0025] The pulling assembly includes a sliding cavity 3 arranged at the end side of the sliding frame 14, a magnet block 31 is slidably assembled in the sliding cavity 3, a plurality of iron blocks 32 matching the magnet block 31 are arranged on the inner wall of the slide groove 13, and iron blocks 32 are arranged at positions of the slide groove 13 matching the positions of the two placement grooves 17.

[0026] When the sliding frame 14 moves in the sliding groove 13, when the position of the magnet block 31 matches the position of the iron block 32, the magnet block 31 absorbs the iron block 32, and the magnet block 31 moves toward the side of the iron block 32 in the sliding cavity 3. The second spring 33 begins to compress, and the magnet block 31 drives the slider 24 to move upward in the inner cavity 23 through the connecting line 35, thereby driving the arc-shaped clamping member 22 to move away from the cleaning wheel 16. When the sliding frame 14 continues to move, the magnet block 31 and the iron block 32 stop moving. Under the action of the extension of the second spring 33, the magnet block 31 is driven to reset, thereby canceling the pull on the slider 24, and the slider 34 resets and slides.

[0027] The cleaning mechanism includes a storage frame 36 arranged on the lower back side of the installation frame 12, and an iron slide plate 37 is slidingly sealed inside the storage frame 36. A magnetic skin 371 matching the iron slide plate 37 is provided on the surface of the sliding frame 14. Telescopic rods 38 are provided on the left and right sides of the upper surface of the iron slide plate 37. The outer surfaces of the two telescopic rods 38 are sleeved with third springs 39. A pressure relief hole 391 is provided on the lower side of the storage frame 36, and a water replenishment mechanism and a water spraying mechanism are connected to the upper side of the storage frame 36.

[0028] When the sliding frame 14 drives the cleaning wheel 16 to move to the position of the lower placement groove 17, when the position of the magnetic skin 371 matches the position of the iron slide plate 37, the magnetic skin 371 adsorbs the iron slide plate 37, driving the iron slide plate 37 to move rapidly upward in the storage frame 36, and the third spring 39 and the telescopic rod 38 begin to compress, and the iron slide plate 37 squeezes the clean water in the storage frame 36 and sprays it outward through the water spraying mechanism, thereby cleaning the outer surface of the cleaning wheel 16. When the sliding frame 14 moves upward, when the position of the magnetic skin 371 and the iron slide plate 37 is staggered, the iron slide plate 37 is driven to slide and reset in the storage frame 36 under the action of the extension of the third spring 39, and negative pressure is formed on the upper side of the storage frame 36, so that clean water is replenished to the upper side of the storage frame 36 through the water replenishing mechanism, so as to facilitate the next cleaning of the surface of the cleaning wheel 16.

[0029] The water spray mechanism includes a cavity 4 arranged in the installation frame 12. The inner surface of the installation frame 12 is provided with a plurality of spray holes 41 connected to the cavity 4. A water outlet hole 42 is provided between the cavity 4 and the storage frame 36. The water outlet hole 42 is equipped with a water outlet check valve 43.

[0030] When the clean water in the storage frame 36 is squeezed, the clean water can enter the cavity 4 through the water outlet hole 42 and then be sprayed outward through the plurality of spray holes 41 to clean the outer surface of the cleaning wheel 16 in the lower placement groove 17.

[0031] The water replenishing mechanism includes a water inlet pipe 44 connected to the upper side of the storage frame 36 . The water inlet pipe 44 is equipped with a water inlet check valve 45 . The other end of the water inlet pipe 44 is connected to a water tank 46 .

[0032] When negative pressure exists in the upper side of the storage frame 36 , clean water in the water tank 46 is sucked into the storage frame 36 through the water inlet pipe 44 .

[0033] The rebound mechanism includes a mounting cavity 47 disposed in the cleaning wheel 16 and surrounding the outer surface of the fixing rod 15. A coil spring 48 is installed in the mounting cavity 47. The two ends of the coil spring 48 are respectively connected to the fixing rod 15 and the inner wall of the mounting cavity 47.

[0034] When the cleaning wheel 16 contacts the outer surface of the photovoltaic panel 1 and starts to rotate, the cleaning wheel 16 drives the coil spring 48 to start to compress. When the cleaning wheel 16 stops contacting the photovoltaic panel 1 and the limiting mechanism stops limiting the cleaning wheel 16, the cleaning wheel 16 can be driven to rotate at high speed under the action of the extension of the coil spring 48.

[0035] The left and right sides of the mounting frame 12 are both provided with driving grooves 5, and screw rods 51 are rotatably mounted in the two driving grooves 5. The two screw rods 51 are both threadedly connected to driving blocks 52 connected to the sliding frame 14, and the two screw rods 51 are transmission-connected to a motor 53.

[0036] Since the driving block 52 is connected to the sliding frame 14 and the driving block 52 is threadedly connected to the screw rod 51, when the screw rod 51 rotates in two directions, the sliding frame 14 can be driven to slide up and down, and the motor 53 can drive the screw rod 51 to rotate in two directions.

[0037] The control box 101 is provided with a line detection module. The line detection module can monitor the voltage, current and power of the photovoltaic panel in real time. By measuring the output power of the photovoltaic panel, it can be determined whether it meets the design standard or expected performance. If the power output is lower than the normal value, it may mean that the photovoltaic panel is faulty or aged and needs to be repaired or replaced in time. Voltage and current are important indicators of photovoltaic panel performance. By measuring these parameters, it can be determined whether the photovoltaic panel is in normal working condition. Abnormal voltage or current values ​​may indicate circuit failure, connection problems or defects in the photovoltaic panel itself. When a fault is detected, the control box 101 transmits the signal to the background management system again to alarm the staff for review.
