[0023] The photovoltaic panel connecting plate 18 is connected to the two hinge blocks 17 at the upper end of the rear supporting leg 12 by means of a pin shaft. At the same time, the threaded column 154 is screwed into the threaded barrel 152, and the length of the threaded column 154 at the upper end of the threaded barrel 152 is adjusted to adjust the inclination angle of the photovoltaic panel connecting plate 18. Therefore, the photovoltaic panel adjustment support frame 1 can be suitable for use in most terrains.

[0024] Specifically, the cleaning air dryer 2 includes two slide rails 201 and a drive motor 202. The two slide rails 201 are respectively fixedly connected to the two lateral end surfaces of the photovoltaic panel connecting plate 18. A walking frame 203 is slidably connected between the two slide rails 201. The two ends of the walking frame 203 are screwed with screws 204 on the lower side of the photovoltaic panel connecting plate 18, and the two screws 204 are rotatably connected to the bottom surface of the photovoltaic panel connecting plate 18. The lower ends of the two screws 204 are fixedly connected with sprockets 205. A chain belt 206 is commonly sleeved between the two sprockets 205.

[0025] When the driving motor 202 is started, it will drive the screw 204 connected to it to rotate, and the two screws 204 are connected together through the sprocket 205 and the chain belt 206, so that the two screws 204 can rotate at the same time, and the screw 204 is screwed together with its traveling frame 203, so that the traveling frame 203 can be driven to move while the screw 204 rotates.

[0026] The specific process of the device when in use is as follows: the counting control box 3 controls the solenoid valve 208 to open, and the water will be discharged from the drainage hole 211 on the drain pipe 210 to flush the photovoltaic panel at a fixed time (the timing time is set in the counting control box 3). After the flushing is completed, the counting control box 3 controls the drive motor 202 and the fan 207 to start, and the fan 207 blows the wind out from the drainage hole 211 on the blowing pipe 209 to blow off the clear water remaining on the surface of the photovoltaic panel to avoid the remaining clear water from leaving water stains on the photovoltaic panel after drying up, and the walking frame 203 is driven by the drive motor 202 to perform a reciprocating motion to increase the air-drying effect.

[0027] Specifically, the counting control box 3 includes an installation box 31, which is fixedly connected to the support plate 14. The installation box 31 is fixedly connected with an electricity meter 32 electrically connected to the photovoltaic panel. The installation box 31 is fixedly connected with an MCU microcontroller 33, a first wireless receiver 35 and a first wireless signal transmitter 34. The MCU microcontroller 33 is electrically connected to the fan 207, the solenoid valve 208, the drive motor 202, the electricity meter 32, the first wireless signal transmitter 34, the first wireless receiver 35 and the external power supply.

[0028] The electricity meter 32 can record the numerical value of the electricity generated by the photovoltaic panel in a period of time, and send the numerical value to the MCU microcontroller 33. The MCU microcontroller 33 sends the numerical value to the first wireless signal transmitter 34. At the same time, the MCU microcontroller 33 can control the start and stop of the fan 207, the solenoid valve 208, and the drive motor 202.

[0029] Specifically, the monitoring station 4 includes a monitoring station body 41, the interior of which is fixedly connected with a motherboard 42 with a CPU, a second wireless transmitter 46 and a second wireless receiver 43, and the upper front side of the monitoring station body 41 is fixedly connected with a display screen 44 and an operation panel 45, the motherboard 42 is electrically connected to the display screen 44, the operation panel 45, the second wireless receiver 43, the second wireless transmitter 46 and an external power supply, and the second wireless receiver 43 is signal-connected to the first wireless signal transmitter 34.

[0030] The second wireless receiver 43 can receive the data sent by the first wireless signal transmitter 34 and compare the data to determine whether the photovoltaic panel is damaged.

[0031] The second wireless transmitter 46 can transmit the command of the monitoring station 4 into the counting control box 3 .

[0032] Working principle: When the utility model is in use, the photovoltaic panel adjustment support frame 1 is fixed on the fixed point, and the angle of the photovoltaic panel connecting plate 18 is adjusted, and then the photovoltaic panel is fixed on the photovoltaic panel connecting plate 18. At the same time, the photovoltaic panel is electrically connected to the counting control box 3, and the counting control box 3 is connected to the monitoring station 4 signal. At the same time, the monitoring station 4 is connected to the signals of multiple counting control boxes 3 within the same range for data comparison of power generation. When the photovoltaic panel generates electricity, the amount of electricity generated in a period of time (two hours or more hours) will be recorded in the counting control box 3 and sent back to the monitoring station 4 by the counting control box 3. The monitoring station 4 will compare the data of power generation of all connected photovoltaic panels. The photovoltaic panels with large data differences are compared. If the data are significantly different, it can be determined that the photovoltaic panel with a large data difference is damaged or that there is a lot of dust on the surface of the photovoltaic panel. The monitoring station 4 will issue an instruction for a single cleaning of the photovoltaic panel to the counting control box 3, and the counting control box 3 will start the cleaning dryer 2 to clean the surface of the photovoltaic panel, and record and compare the power generation in the next time period. If the data difference is still large, it can be determined that the photovoltaic panel with a large data difference is damaged and displayed on the display screen 44. At this time, the maintenance personnel can watch the records on the display screen and carry out targeted maintenance, thereby reducing the workload of the maintenance personnel. At the same time, it can be determined with a high probability that the photovoltaic panel is damaged, reducing the complexity of the maintenance personnel's inspection.

[0033] Based on the above operations, the device can manually start the cleaning dryer 2 through the operation panel 45 on the monitoring station 4 to perform regular cleaning of all its photovoltaic panels to prevent all photovoltaic panels from being covered with dust, which would cause the device to be unable to perform correct data comparison and thus be unable to perform the above operation process.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
