[0021] In this embodiment, the first motor 9 drives the rotating rod 11 on the output shaft 10 to rotate. The rotating rod 11 drives the installation cylinder 12 to rotate 360 degrees around the output shaft 10. By changing the angle of the installation cylinder 12, the angle of the solar total radiation sensor 7 on the circular plate 6 is adjusted.

The four solar panels 8 are respectively located inside the four receiving grooves 31. The solar panel 8 is fixedly installed with the connecting slider 32. Wherein the connecting slider 32 is limited and slides with the receiving groove 31, and the driving groove 26 is in communication with the four receiving grooves 31, and the first mounting shaft 29 and the second mounting shaft 33 are not in the same direction, and the driving rod 30 is in an inclined state.

[0023] In this embodiment, the second motor 23 drives the driving gear 25 on the driving shaft 24 to rotate. By utilizing the meshing of the driving gear 25 and the driven gear 28, the driven gear 28 rotates in the driving groove 26 through the auxiliary shaft 27. When the driven gear 28 rotates, it drives the driving rod 30 to rotate at an angle with the auxiliary shaft 27 as the center through the driving shaft 24. By utilizing the cooperation between the driving rod 30 and the second mounting shaft 33 and the cooperation between the connecting slider 32 and the receiving groove 31, the connecting slider 32 is used to drive the solar panel 8 to move out of the receiving groove 31. By storing and extending the solar panel 8, it is ensured that the solar panel 8 is protected when encountering unsuitable weather conditions outside, effectively improving the use effect of the solar panel 8, and at the same time improving the use effect of the detection device.

[0025] In this embodiment, when the driving component is used to adjust the position of the solar panel 8, the solar panel 8 during the adjustment process will pass between the upper support rod 36 and the lower support rod 37. By using the cleaning brushes 38 on the upper support rod 36 and the lower support rod 37, the impurities and dust on the solar panel 8 can be effectively cleaned, ensuring that the solar panel 8 can effectively enter the interior of the storage groove 31, and at the same time ensuring that the solar panel 8 will not be affected by some impurities and dust to its own use effect.

[0026] Working principle: During use, the entire device is installed at a designated monitoring position through the support rod 1; Then, the first motor 9 drives the rotating rod 11 on the output shaft 10 to rotate. The rotating rod 11 drives the mounting cylinder 12 to rotate 360 degrees around the output shaft 10. By changing the angle of the mounting cylinder 12, the angle of the solar total radiation sensor 7 on the circular plate 6 is adjusted. When the angle adjustment is completed, the electric push rod 19 drives the mounting ring 21 on the positioning plate 20 to adjust the height. The limiting ball 18 on the L-shaped rod 17 is slidably limited in the annular groove 22 on the mounting ring 21. At the same time, the L-shaped rod 17 will be limited and rotated in the mounting cylinder 12 through the fixed ring 16 and the rotating ring 13, so that the solar total radiation sensor 7 rotates around the mounting rod 14 to adjust the angle. By adjusting the azimuth and height of the solar total radiation sensor 7, the solar radiation data can be collected more accurately; The second motor 23 drives the driving gear 25 on the driving shaft 24 to rotate. By using the meshing of the driving gear 25 and the driven gear 28, the driven gear 28 rotates in the driving groove 26 through the auxiliary shaft 27. When the driven gear 28 rotates, it drives the driving rod 30 to rotate around the auxiliary shaft 27 through the driving shaft 24. By using the cooperation of the driving rod 30 and the second mounting shaft 33 and the cooperation of the connecting slider 32 and the storage groove 31, the connecting slider 32 drives the solar panel 8 to move out of the storage groove 31. By storing and extending the solar panel 8, it is ensured that the solar panel 8 is protected when encountering unsuitable weather outside, effectively improving the use effect of the solar panel 8; When it is necessary to use the solar panel 8 for light energy charging, the first motor 9 drives the rotating rod 11 on the output shaft 10 to rotate. The rotating rod 11 drives the mounting cylinder 12 to rotate at an angle around the output shaft 10, so that the solar panel 8 has the same illumination angle as the sun. At the same time, the electric push rod 19 drives the mounting ring 21 on the positioning plate 20 to adjust the height. The limiting ball 18 on the L-shaped rod 17 is slidably limited in the annular groove 22 on the mounting ring 21. At the same time, the L-shaped rod 17 will be limited and rotated in the mounting cylinder 12 through the fixing ring 16 and the rotating ring 13, so that the solar panel 8 is always at the best angle with the sun. Through the power supply of the solar panel 8, it effectively ensures that the monitoring device has enough power for use; When the position of the solar panel 8 is adjusted by the driving assembly, the solar panel 8 during the adjustment process will pass between the upper support rod 36 and the lower support rod 37. The cleaning brushes 38 on the upper support rod 36 and the lower support rod 37 can effectively clean the impurities and dust on the solar panel 8, ensuring that the solar panel 8 can effectively enter the inside of the storage groove 31.

[0027] In this technical solution, when the angle of the solar panel 8 needs to be adjusted, the solar total radiation sensor 7 can be in a working state or a non-working state, as long as it is ensured that the angle adjustment of the solar panel 8 does not affect the use of the solar total radiation sensor 7.
