Specifically, the output end of the stepper motor 32 is fixedly connected to the outer end of one of the rotating rods 14, and the stepper motor 32 is fixedly installed on the outer wall of the sleeve block 13. The outer walls on both sides of the rotating rod 14 are fixedly connected to the side frames 15, and the outer walls of the side frames 15 are fixedly connected to the first gears 16, and the two first gears 16 are meshed with each other. When the stepper motor 32 is energized, the rotating rod 14 is rotated, and under the action of the mutual meshing of the two first gears 16, the side frames 15 on both sides are rotated synchronously, thereby realizing the precise adjustment of the side frames 15 at the bottom of the photovoltaic panel driven by the stepper motor 32;

[0057] Furthermore, a fixed block 17 is fixedly installed on the outer wall of one end of the side frame 15 close to the rotating rod 14, and the top of the fixed block 17 is fixedly connected to an electric push rod 18, and the top of the electric push rod 18 is fixedly connected to a top plate 19.

The outer wall of the connecting shaft 23 is rotatably connected to the second movable plate 24, and the outer wall of the second movable plate 24 is rotatably connected to the telescopic block 25. The telescopic block 25 is slidably connected to the outer wall of the side frame 15, and multiple telescopic blocks 25 are connected by multiple second movable plates 24, and the second movable plates 24 rotatably connected on both sides are meshed. The first movable plate 22 and the second movable plate 24 are connected, forming a "V"-shaped structure symmetrically arranged up and down. Under the action of the "V"-shaped structure of the first movable plate 22 and the second movable plate 24, the first movable plate 22 and the second movable plate 24 symmetrically arranged up and down can be synchronously extended and retracted, ensuring the balance of movement of the telescopic block 25. Moreover, under the action of the multiple second movable plates 24 connected and meshed, the transmission effect of each second movable plate 24 is achieved, and the structure is simple and the stability is high. At the same time, in order to realize the driving of the continuous first movable plates 22 and the second movable plates 24, the outer wall of one of the first movable plates 22 is fixedly connected to the second gear 21, and the outer wall of the second gear 21 is meshed with the rack 20, the rack 20 is slidably connected to the outer wall of the fixed block 17, and the top of the rack 20 is fixedly installed with a top plate 19.

[0058] Furthermore, the top of the telescopic block 25 is fixedly connected to a connecting rod 26, and a plurality of temperature measuring units are equidistantly installed on the top of the connecting rod 26. Specifically, the temperature measuring unit includes a reset spring 27, which is fixedly installed on the top of the connecting rod 26. The top of the reset spring 27 is fixedly connected to a temperature sensor 28, and the bottom of the temperature sensor 28 is fixedly installed with a guide rod 29. The guide rod 29 is located inside the reset spring 27. The bottom end of the guide rod 29 is fixedly connected to a magnetic column 30, and an electromagnetic block 31 is provided below the magnetic column 30. The electromagnetic block 31 is embedded in the surface of the connecting rod 26, and the magnetic pole at the bottom of the magnetic column 30 is in contact with the electromagnetic block. The magnetic poles on the surface of 31 are opposite. Under the action of the opposite magnetic poles of the magnetic column 30 and the electromagnetic block 31, when the electromagnetic block 31 is energized to release the magnetism, the magnetic column 30 moves upward under the action of the opposite magnetic poles, causing the reset spring 27 to stretch, so that the magnetic column 30 drives the temperature sensor 28 at the bottom to move upward, making it convenient to install the temperature sensor 28 at the bottom of the photovoltaic panel to measure the temperature of the photovoltaic panel.

At the same time, the bidirectional motor 9 is energized and driven back and forth, so that the gear column 8 rotates on the surface of the gear column 4, so that the movable seat 7 reciprocates above the gear column 4 through the slide 6. Under the action of the rotating connecting plate 10 above the movable seat 7, the gear disk 12 engages with the tooth groove plate 3, so that the rotating plate 10 drives the surface thermal imager 11 to rotate and patrol. The thermal imager 11 reciprocates and patrols above the photovoltaic panel, and under the action of the temperature sensor 28 arranged at the bottom of the photovoltaic panel, the photovoltaic panel is simultaneously monitored for faults by the thermal imager 11 and the temperature sensor 28 in real time. When an abnormal temperature is detected, the alarm is synchronized to alert the user.

Temperature measurement installation: After the device is set in place and stabilized, the stepper motor 32 drives the rotating rod 14 to rotate, and the rotating rod 14 on the inner side of the column 2 drives the side frame 15 to rotate, so that the side frames 15 on both sides rotate and unfold under the photovoltaic panel. After the side frames 15 rotate to the appropriate position, the electric push rod 18 is energized and retracted, so that the electric push rod 18 drives the rack 20 to move downward through the top plate 19. Under the meshing action of the rack 20 and the second gear 21, the two symmetrically meshed first movable plates 22 rotate synchronously. By rotating the other end of the first movable plate 22 to connect the second movable plate The movable plate 24 stretches the plurality of continuously arranged first movable plates 22 and the second movable plates 24, thereby extending the plurality of continuously arranged telescopic blocks 25 on the outer wall of the side frame 15, so that the telescopic blocks 25 drive the connecting rods 26 at the top to extend over a large area at the bottom of the photovoltaic panel. Under the action of the electromagnetic block 31 engaged with the surface of the connecting rod 26, by arranging the magnetic poles of the electromagnetic block 31 and the magnetic column 30 in opposite directions, when the electromagnetic block 31 is energized, the magnetic column 30 at the bottom drives the temperature sensor 28 to move upward, so that the temperature sensor 28 is installed in close contact with the bottom of the photovoltaic panel to measure the temperature of the photovoltaic panel;

[0063] S3. Infrared patrol: The bidirectional motor 9 is driven back and forth, causing the gear column 8 to rotate on the surface of the gear column 4, so that the movable seat 7 moves back and forth above the gear column 4 via the slide plate 6. Under the action of the rotating connecting plate 10 above the movable seat 7, the gear plate 12 is engaged with the tooth groove plate 3, so that the rotating plate 10 drives the surface thermal imager 11 to rotate and patrol;

[0064] S4. Fault alarm: The thermal imager 11 moves back and forth and rotates above the photovoltaic panel to patrol, and the temperature sensor 28 is set at the bottom of the photovoltaic panel. The photovoltaic panel is simultaneously monitored for faults by the thermal imager 11 and the temperature sensor 28 in real time. When an abnormal temperature is detected, the alarm is synchronized to alert the user.

[0065] In summary, by arranging a thermal imager 11 on the top of the device, the thermal imager 11 can detect hot spots and hidden cracks on the surface of the solar photovoltaic panel from above, and by arranging a sleeve block 13 and a telescopic temperature measuring component at the bottom of the column 2, multiple telescopic blocks 25 can install multiple temperature sensors 28 at the bottom of the photovoltaic panel at different positions, which is convenient for accurate temperature detection of the photovoltaic panel and efficient early warning of abnormal temperature rise of the photovoltaic panel. Moreover, through the setting of the alarm, the device can issue a real-time alarm after multi-dimensional detection of the photovoltaic panel, ensuring the fault detection effect and automatic alarm efficiency of the solar photovoltaic panel. Compared with the current manual inspection, the work efficiency is higher, and it is convenient to timely discover defects and safety hazards, which solves the technical problem that the current solar photovoltaic panel fault automatic alarm device cannot perform real-time monitoring and automatic alarm detection of abnormal temperature rise, hidden cracks and hot spot faults of the solar photovoltaic panel.
