[0026] In the present invention, moving wheels 23 are provided at the four corners of the bottom of the two support columns 1 .

[0027] In the present invention, the optical sensor 27, the first drive motor 3, the second drive motor 8, the third drive motor 11, the fourth drive motor 14, the dust removal fan 1502, the cleaning motor 1604, the water suction motor 1705 and the water pump 21 are respectively electrically connected to the controller and are uniformly controlled by the controller. The specific model and power of each motor can be selected according to the specific situation by ordinary technicians in this field.

[0028] The present invention also provides a technical solution, a self-cleaning method for a solar photovoltaic panel with a self-cleaning function, comprising the following steps: The light sensor 27 is used to detect the reflectivity of the surface of the solar photovoltaic panel 24, thereby obtaining the dust coverage of the surface of the solar photovoltaic panel 24; When the dust coverage is greater than a preset value, the angle of the entire cleaning assembly is adjusted by the angle adjustment mechanism, and the dust removal mechanism 15, the cleaning mechanism 16 and the water absorption mechanism 17 are simultaneously started to perform cleaning work along the forward direction of the lateral moving mechanism; When the dust coverage is equal to the preset value, the angle of the entire cleaning assembly is adjusted by the angle adjustment mechanism, and the dust removal mechanism 15 and the cleaning mechanism 16 are simultaneously started to perform cleaning along the forward direction of the lateral moving mechanism; When the dust coverage is less than a preset value, the angle of the entire cleaning assembly is adjusted by the angle adjustment mechanism, and the dust removal mechanism 15 is simultaneously started to perform cleaning along the forward direction of the lateral moving mechanism.

[0029] Embodiment 1: When in use, first move the entire device to the solar photovoltaic panel 24 that needs to be cleaned by the moving wheel 23. Then adjust the position of the entire cleaning assembly by the lateral moving mechanism and the angle adjustment mechanism to ensure that the light sensor 27 can detect the reflectivity of the surface of the solar photovoltaic panel 24. Then obtain the dust coverage on the surface of the solar photovoltaic panel 24. The light sensor 27 can measure the reflection intensity after the light hits the surface of the object. When the surface of the solar photovoltaic panel 24 is covered with dust, the intensity and distribution of its reflected light will change. Therefore, by measuring the intensity and distribution of the reflected light by the light sensor 27, the dust coverage on the surface of the solar photovoltaic panel 24 can be indirectly inferred. The light sensor 27 is used to receive the reflected light and convert it into an electrical signal for measurement, and output the electrical signal to the data collector. The data collector converts the electrical signal into digital data for processing. Finally, the collected data is processed and analyzed by the data processing unit to evaluate the reflectivity and dust coverage of the photovoltaic panel surface. When the dust coverage is greater than the preset value, that is, when there is a lot of dust and debris, the angle of the entire cleaning component is adjusted by the angle adjustment mechanism, and the dust removal mechanism 15, the cleaning mechanism 16 and the water absorption mechanism 17 are started simultaneously to perform cleaning along the forward direction of the lateral moving mechanism. The dust removal mechanism 15 uses the dust removal fan 1502 in conjunction with the dust removal pipeline 1503 and the air outlet 1504 with an overall flat trumpet structure to blow air on the surface of the solar photovoltaic panel 24, and preliminarily treats the dust and debris on the surface of the solar photovoltaic panel 24, such as fallen leaves; the cleaning mechanism 16 uses the water pump 21 in conjunction with the water pipe 22, the winding mechanism 19 and the water supply Under the action of the flushing pipe 1602, the water pipe 18 flushes the cleaning brush 1606 on the surface of the rotating roller 1605. At the same time, the rotating roller 1605 can rotate under the drive of the cleaning motor 1604, so as to clean the surface of the solar photovoltaic panel 24. At the same time, in the process of moving forward, the scraper 1607 can preliminarily deal with the residual water stains; the water absorption mechanism 17 works through the water absorption motor 1705, cooperates with the linear water absorption squeegee 1703 and the arc water absorption squeegee 1702 and the water absorption hole 1704, can improve the cleaning effect of the water stains, and avoid that the water stains cannot be completely cleaned after scraping off the water stains. At the same time, before cleaning, the collection tank 26 is rotated out from the side of the support column 1 under the action of the rotating shaft 25, and then the collection tank 26 with a telescopic structure as a whole is stretched to an appropriate length according to the length of the solar photovoltaic panel 24. Collect the cleaned sewage uniformly.

[0030] The controller controls the second drive motor 8, the third drive motor 11 and the fourth drive motor 14 to adjust the angle between the first connecting rod 10 and the hinge seat 9, the angle between the first connecting rod 10 and the second connecting rod 13, and the angle between the second connecting rod 13 and the cleaning assembly, so as to ensure that the cleaning assembly can be adapted to the solar photovoltaic panels 24 with different tilt angles. When the second drive motor 8 rotates forward, the drive shaft of the second drive motor 8 drives the first connecting rod 10 to rotate upward along the hinge seat 9, otherwise the first connecting rod 10 rotates downward. When the third drive motor 11 rotates forward, the drive shaft of the third drive motor 11 drives the second connecting rod 13 to rotate downward at the end of the first connecting rod 10, otherwise the second connecting rod 13 rotates upward; when the fourth drive motor 14 rotates forward, the drive shaft of the fourth drive motor 14 drives the cleaning assembly to rotate upward at the end of the second connecting rod 13, otherwise the cleaning assembly rotates downward.

[0031] The controller controls the first drive motor 3 to rotate forward and reverse, thereby controlling the moving block 7 to move left and right along the slide rail 5 on the lead screw 4. When the first drive motor 3 rotates forward, the moving block 7 moves left along the slide rail 5 on the lead screw 4. When the first drive motor 3 rotates reversely, the moving block 7 moves right along the slide rail 5 on the lead screw 4, thereby driving the entire angle adjustment mechanism and the cleaning component to move. For a solar photovoltaic panel 24 whose width is greater than the cleaning component, the above adjustment method can be repeated for repeated adjustment.

[0032] During cleaning, the surface of the solar photovoltaic panel 24 is first blown by the dust removal fan 1502 in cooperation with the dust removal duct 1503 and the air outlet 1504 with an overall flat trumpet structure, so as to preliminarily deal with the dust and debris, such as fallen leaves, on the surface of the solar photovoltaic panel 24.

[0033] Then, the water pump 21 cooperates with the water pipe 22, the winding mechanism 19 and the water supply pipe 18 to flush the cleaning brush 1606 on the surface of the rotating roller 1605 under the action of the flushing pipe 1602. At the same time, the rotating roller 1605 can rotate under the drive of the cleaning motor 1604, so as to clean the surface of the solar photovoltaic panel 24. At the same time, during the forward movement, the scraper 1607 can preliminarily process the residual water stains. The overall height of the cleaning shell 1601 is lower than the cleaning brush 1606 and the scraper 1607, so as to avoid the cleaning shell 1601 from damaging the solar photovoltaic panel 24 during the cleaning process. The scraped water stains will fall into the collection tank 26 for unified collection.

[0034] Finally, by working the water suction motor 1705 of the water suction mechanism 17, in cooperation with the linear water suction squeegee 1703, the arc-shaped water suction squeegee 1702 and the water suction hole 1704, the cleaning effect of water stains can be improved to avoid the situation where the water stains cannot be completely cleaned after scraping off the water stains in one time of water suction.

[0035] Embodiment 2: The difference between this embodiment and Embodiment 1 is that when the dust coverage is greater than a preset value, that is, when the dust and debris are relatively small, the angle of the entire cleaning assembly is adjusted by the angle adjustment mechanism, and the dust removal mechanism 15 and the cleaning mechanism 16 are started at the same time, and the cleaning work is performed along the forward direction of the lateral moving mechanism according to the working principle described in Embodiment 1.

[0036] Embodiment 3: Compared with Embodiment 1, the difference between this embodiment is that when the dust coverage is less than the preset value, that is, when there is only a small amount of dust and no debris, the angle of the entire cleaning assembly is adjusted by the angle adjustment mechanism, and the dust removal mechanism 15 is started at the same time according to the working principle described in Embodiment 1, and cleaning work is performed along the forward direction of the lateral moving mechanism.
