[0026] A troubleshooting device for photovoltaic panels, such as Figure 1-4 As shown, it includes a drone 1 and a mounting plate 2; the mounting plate 2 is fixedly connected to the lower part of the drone 1; the drone 1 has a built-in center of gravity detector;

[0027] It also includes a center of gravity moving unit, an angle adjustment unit, an EL detector 3 and a gravity adjustment unit; the center of gravity moving unit is connected to the mounting plate 2; the angle adjustment unit is connected to the center of gravity moving unit; one side of the angle adjustment unit is connected to the EL detector 3; the other side of the angle adjustment unit is connected to the gravity adjustment unit.

[0028] The center of gravity moving unit includes a slide plate 101, an elastic member 102 and an electric push rod 103; the slide plate 101 is slidably connected to the lower part of the mounting plate 2; two elastic members 102 are fixedly connected to opposite sides of the slide plate 101; all the elastic members 102 are fixedly connected to the slide plate 101; an electric push rod 103 is bolted to one side of the mounting plate 2; the telescopic part of the electric push rod 103 is fixedly connected to the slide plate 101, and the electric push rod 103 is located between the two elastic members 102 on the same side; the slide plate 101 is connected to the angle adjustment unit.

[0029] The angle adjustment unit includes a mounting bracket 201, a motor 202, a mounting bracket 203, a motor 204 and a U-shaped plate 205; the middle part of the skateboard 101 is fixedly connected with the mounting bracket 201; the lower part of the mounting bracket 201 is bolted to the motor 202; the output shaft of the motor 202 is fixedly connected with the mounting bracket 203; one side of the mounting bracket 203 is bolted to the motor 204; the output shaft of the motor 204 is fixedly connected with the U-shaped plate 205; the U-shaped plate 205 is detachably connected to the EL detector 3; the other side of the mounting bracket 203 is connected to the gravity adjustment unit.

[0030] The gravity adjustment unit includes a water storage box 301, a cover 302, an electric push rod 2 303 and a slide column 304; the water storage box 301 is fixedly connected to the other side of the mounting bracket 203; the cover 302 is screwed on the upper part of the water storage box 301; a mounting groove 301a is provided on the water storage box 301; the electric push rod 2 303 is bolted in the mounting groove 301a; the slide column 304 is fixedly connected to the telescopic part of the electric push rod 2 303; the slide column 304 is plugged into the water storage box 301; and a drainage hole 304a is provided on the slide column 304.

[0031] Each of the three supporting feet of the drone 1 is covered with a rubber sleeve 4. When the drone 1 lands, the rubber sleeve 4 will first contact the ground to play a buffering and shock-absorbing role.

[0032] The frame of the drone 1 is hollow. When wind blows, the hollow frame of the drone 1 can reduce the impact of the wind on the drone 1 and prevent the frame of the drone 1 from being blown crooked by the wind.

[0033] For the rotation described below, the viewing direction is from front to back, from top to bottom, and from right to left. When in use, the operator first places the troubleshooting device for photovoltaic panels at the required position, connects the electric push rod 103, the motor 202, the motor 204 and the electric push rod 2 303 to the built-in power supply of the drone 1, and then removes the cover 302 from the water storage box 301, adds a sufficient amount of water into the water storage box 301, and then puts the cover 302 back on the water storage box 301. Since the hidden cracks on the photovoltaic panels cannot be observed manually, the EL detector 3 is required to detect them. The manual detection steps of the photovoltaic panels using the EL detector 3 are relatively cumbersome, time-consuming, and inefficient. In addition, when some photovoltaic panels are installed at high altitudes and on roofs, manual detection requires manual high-altitude and high-risk environment operations, which poses a safety hazard. Therefore, when the operator needs to inspect the photovoltaic panels, When testing, the drone 1 is controlled to start, and the gravity moving unit, angle adjustment unit, EL detector 3 and gravity adjustment unit are carried out together for test flight. Because the EL detector 3 is installed on the drone 1 later, the gravity center of the drone 1 will be offset and will not be centered. During the test flight, the gravity center detector on the drone 1 is started to determine whether the gravity center of the drone 1 is centered at this time. If the gravity center of the drone 1 is not in the middle but on the left, the electric push rod 103 is controlled to be pushed out, driving the skateboard 101, the mounting bracket 201, the motor 1 202, the mounting bracket 203, the motor 204, the U-shaped plate 205 and the EL detector 3 to move to the right together, forcing the two elastic members 102 on the left to stretch and the two elastic members 102 on the right to compress, so that the gravity center of the drone 1 moves to the right, until the gravity center of the drone 1 returns to the middle, and then the electric push rod 103 is controlled to stop;

[0034] If the center of gravity of the drone 1 is on the right, the electric push rod 103 is controlled to contract, driving the connected parts to move to the left, forcing the two elastic parts 102 on the left to compress and the two elastic parts 102 on the right to stretch, so that the center of gravity of the drone 1 moves to the left. After the center of gravity of the drone 1 returns to the middle, the electric push rod 103 is controlled to stop. In this way, the electric push rod 103 pushes the skateboard 101 and the connected parts to move, thereby adjusting the center of gravity of the drone 1 and keeping the center of gravity of the drone 1 in the middle, thereby avoiding the problem that the drone 1 cannot maintain balance due to the influence of the center of gravity during flight, resulting in the EL detector 3 being unable to detect the photovoltaic panel.

[0035] When the drone 1 is flying with the center of gravity moving unit, the angle adjustment unit and the EL detector 3, since the motor 204 is only provided on one side of the mounting bracket 203, when the drone 1 is blown by the wind, with the EL detector 3 as the center, the wind resistance on one side of the motor 204 is larger, and the wind resistance on the other side is larger, which may easily cause the drone 1 to become unbalanced and tilted, causing the drone 1 to crash. Therefore, by providing a water storage box 301, a cover 302, an electric push rod 203 and a sliding column 304 on the other side of the mounting bracket 203, the wind resistance on both sides of the EL detector 3 is made consistent, thereby avoiding the phenomenon of unbalanced wind resistance of the drone 1 during flight. At the same time, the water storage box 301, the cover 302, the electric push rod 203 and the sliding column 304 are provided on the other side of the mounting bracket 203. 01, and the water storage box 301 can also achieve the effect of counterweight. When the drone 1 flies in front of the photovoltaic panel, the EL detector 3 is controlled to rotate so that the lens of the EL detector 3 faces the photovoltaic panel for detection. After the adjustment of the EL detector 3 is completed, the center of gravity on the drone 1 changes, resulting in a heavier side of the drone 1 close to the water storage box 301. The electric push rod 303 is controlled to be pushed out to drive the slide column 304 to move downward, so that the drainage hole 304a is connected with the inside of the water storage box 301, and the water in the water storage box 301 is discharged from the drainage hole 304a, so that the weight of one side of the water storage box 301 is reduced, thereby achieving the effect of real-time counterweight and ensuring the weight balance of the drone 1.

[0036] When the drone 1 flies to the front of the photovoltaic panel to be inspected and remains stationary in the air, the output shaft of the motor 1 202 is controlled to rotate clockwise, driving the mounting bracket 203, the motor 204, the U-shaped plate 205, the EL detector 3, the water storage box 301, the cover 302, the electric push rod 2 303 and the slide column 304 to rotate together, so that the EL detector 3 faces the upper surface of the photovoltaic panel, and then the output shaft of the motor 204 is controlled to rotate clockwise, driving the U-shaped plate 205 and the EL detector 3 to rotate together, so that the lens of the EL detector 3 faces the inclined photovoltaic panel. The EL detector 3 is controlled to automatically focus and switch between multiple modes to detect the photovoltaic panel. After the detection is completed, the detection data is transmitted to the operator's computer. The EL detector 3 is carried by the drone 1 to the photovoltaic panel that needs to be detected. In this way, the quality inspection of the photovoltaic panel can be completed quickly and efficiently, saying goodbye to tediousness, improving work efficiency, realizing the automation process of power work, and effectively reducing operation and maintenance costs. At the same time, it can replace personnel to perform operations in high-altitude and high-risk environments, making EL detection of photovoltaic panels safer.
