A through hole located on the lower side of the assembly plate 7 is opened on the lower side of the adjusting rod 3. The synchronous belt 17 passes through the through hole.

[0030] A housing 18 is provided between the rotating ring 9 and the mounting plate 7. A bidirectional motor 19 is arranged inside the housing 18. Jack holes corresponding to the driving ends of the bidirectional motor 19 are provided on both the upper and lower sides of the housing 18. Connecting rods 20 corresponding to the jack holes are arranged on both the upper and lower sides of the housing 18. The connecting rods 20 are connected to the adjusting rod 3 through bearing seats, and the connecting rods 20 are connected to the driving ends of the bidirectional motor 19 through connecting components. A gear 21 meshing with the gear ring 11 is arranged on the connecting rod 20 on the upper side of the housing 18. The connecting rod 20 on the lower side of the housing 18 is connected to the upper side of the second rotating shaft 14.

[0031] The connecting component includes an electric push rod 22 arranged on the upper side of the housing 18. The output end of the electric push rod 22 penetrates the upper side wall of the housing 18 and is connected to a lifting plate 23. A spring 24 is arranged on one side of the lower side of the lifting plate 23. A sleeve 25 is sleeved on the lower side of the connecting rod 20. Limiting grooves are arranged on the inner walls of both sides of the sleeve 25. The lower side of the connecting rod 20 is slidably connected to the guiding groove.

[0032] The lower side of the sleeve 25 penetrates the jack hole. A partition 26 is arranged on the lower side inside the sleeve 25. A hexagonal prism 27 is arranged on the lower side of the partition 26. A hexagonal hole corresponding to the hexagonal prism 27 is arranged on the driving end of the bidirectional motor 19. The lower side of the spring 24 is connected to an annular plate 28. An annular groove corresponding to the annular plate 28 is arranged on the lower side of the sleeve 25. The annular plate 28 is slidably connected to the annular groove.

[0033] The fixing component includes a support block 29 installed on one side of the base 1. A fixing anchor rod 30 is threadedly connected to the upper side of the support block 29. A soil humidity sensor 31 is embedded in the lower side of the fixing anchor rod 30. A handle is arranged on the upper side of the fixing anchor rod 30.

[0034] The cleaning component includes an exhaust block 32 arranged on the upper side of the photovoltaic panel 8. A conveying pipe 33 is communicated with the rear side of the exhaust plate. An exhaust chamber 34 is arranged on one side of the protective shell 12. One side of the conveying pipe 33 is communicated with the exhaust chamber 34. The inside of the exhaust block 32 is hollow. Exhaust ports 35 are uniformly arranged on the front side of the exhaust block 32.

[0035] It should be noted that before the device is used, the operator can insert the auxiliary anchor rods 37 on both sides of the lower part of the base 1 into the soil, and then turn the fixing anchor rod 30 by using the handle to insert the fixing anchor rod 30 into the soil as well. The cooperation of the fixing anchor rod 30, the auxiliary anchor rod 37 and the Z-shaped support block 29 can complete the fixation of the base 1 and the main rod 2. Among them, a soil humidity sensor 31 is embedded in the lower side of the fixing anchor rod 30 for detecting the soil humidity. The soil humidity sensor 31 adopts a wireless sensor. Through the Internet of Things technology, the data can be quickly and actively reported to the cloud platform, and the user can browse the data on the computer or mobile phone at any time and anywhere.

[0036] In addition, the height of the adjusting rod 3 can be adjusted according to the usage requirements, and the adjusted height of the adjusting rod 3 can be limited by the cooperation of the positioning hole and the fixing bolt. After the device is fixed, the monitoring sensor 5 and the monitoring camera 6 on the upper side of the assembly frame 4 can monitor the forest environment. The monitoring sensor 5 can be one or more of sensors such as a temperature and humidity sensor, a light sensor, a rain sensor, and a wind direction and wind speed sensor, and can respectively perform real-time monitoring operations on the temperature and humidity, light, rain, and wind direction and wind speed inside the forest;

[0037] During the monitoring process, there may be a situation where birds fly around the device. At this time, the infrared sensor 36 can monitor the approach of the birds. When the birds are detected, the bidirectional motor 19 runs at a slow speed. At the same time, the electric push rod 22 on the upper side of the housing 18 runs and drives the sleeve 25 to descend, so that the partition 26 and the hexagonal prism 27 inside the sleeve 25 descend. At this time, under the action of the lifting plate 23 and the spring 24, the lower wall surface of the hexagonal prism 27 will continuously adhere to the upper wall surface of the driving end of the bidirectional motor 19. When the driving end of the bidirectional motor 19 continuously rotates, at a certain moment, the hexagonal hole of the driving end of the bidirectional motor 19 will correspond to the hexagonal prism 27. At this time, the spring 24 will push the hexagonal prism 27 into the hexagonal hole. Subsequently, the bidirectional motor 19 runs normally and can drive the sleeve 25, the connecting rod 20, and the gear 21 to rotate in cooperation with the hexagonal prism 27. Furthermore, in cooperation with the gear ring 11, it can drive the rotating ring 9 and the wind cup 10 to rotate, thereby realizing the automatic bird repelling operation and preventing the birds from approaching the device and causing damage to the device. A bird repelling bell 40 is arranged under the wind cup 10, which can shake and make a sound while the wind cup 10 rotates, increasing the bird repelling effect.

[0038] Since the device is inside the forest, after the device is used for a period of time, fallen leaves are likely to adhere to the photovoltaic panel 8, and it is necessary to regularly clean the surface of the photovoltaic panel 8. At this time, the electric push rod 22 on the lower side of the housing 18 runs. Similarly, the hexagonal prism 27 on the lower side of the housing 18 is connected to the driving end on the lower side of the bidirectional motor 19. The second rotating shaft 14 is driven to rotate by the connecting rod 20 on the lower side of the housing 18. Since the lower sides of the second rotating shaft 14 and the first rotating shaft 13 are connected by a synchronous pulley 15 and a synchronous belt 17, the bidirectional motor 19 can drive the first rotating shaft 13 and the second rotating shaft 14 to rotate synchronously and drive the fan blade 16 to rotate, thereby generating wind. Subsequently, the wind is sent into the exhaust block 32 through the exhaust chamber 34 and the conveying pipe 33 and finally discharged through a plurality of air outlets 35, thereby blowing off the fallen leaves adhering to the surface of the photovoltaic panel 8 and achieving the effect of cleaning the photovoltaic panel 8. At the same time, the front end of the air outlet 35 is inclined, so that the blown wind is inclined downward, thereby increasing the efficiency of blowing off the fallen leaves on the photovoltaic panel 8.

[0039] When the device is running, it may be necessary to perform bird repelling operations and cleaning operations on the photovoltaic panel 8 simultaneously. At this time, the electric push rods 22 located on the upper and lower sides of the housing 18 operate synchronously, enabling the above functions to be achieved simultaneously without interference between the two operations.

[0040] A pair of conical blocking covers 38 are sleeved on the lower side of the adjusting rod 3. Annular sheets are arranged on the upper sides of the conical blocking covers 38. The front and rear sides of the two annular sheets are connected by bolt-nut combinations, which can prevent small animals such as squirrels from climbing onto the device through the adjusting rod 3 and the main rod 2, affecting the normal operation of the device.

[0041] A guide rod 39 is arranged inside the housing 18. One side of the lifting plate 23 is slidably connected to the guide rod 39 to increase the lifting stability of the lifting plate 23.

[0042] A signal transmitting device 41 is arranged on the front side of the assembly frame 4, which can transmit the monitoring data of the device. Positioning holes are evenly opened on the lower side of the adjusting rod 3, and fixing bolts corresponding to the positioning holes are arranged on the front side of the main rod 2, facilitating the fixing of the height of the adjusting rod 3 after the height adjustment of the adjusting rod 3 is completed.

[0043] In this technical solution, the signal transmitting device 41 is internally provided with an embedded computing module, which is connected to the above-mentioned multiple groups of sensors and is responsible for initially processing the collected data, such as data filtering, format conversion, etc., to improve the data transmission efficiency and accuracy. Subsequently, the ZigBee low-power wide area network technology is adopted to realize the wireless transmission between the sensor network and the data center.

[0044] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
