[0028] like Figure 2 As shown, the photovoltaic power generation panel 25 is embedded in the fixed plate 3, and the upper surface of the photovoltaic power generation panel 25 is flush with the upper surface of the fixed plate 3, which is convenient for the automatic cleaning component to clean the photovoltaic power generation panel 25.

[0029] like Figure 3As shown, the photosensitive component includes a first photosensitive sensor 26 and a second photosensitive sensor 27 and they are respectively located on the upper and lower sides of the photovoltaic power generation panel 25. The signal sending end of the first photosensitive sensor 26 and the second photosensitive sensor 27 are connected to the signal receiving end of the controller 13. The first photosensitive sensor 26 and the second photosensitive sensor 27 can identify the angle and light intensity of sunlight from different positions, which can improve the recognition accuracy of the photosensitive component for sunlight, and is conducive to smoothly adjusting the solar power generation device to a suitable angle. The first photosensitive sensor 26 and the second photosensitive sensor 27 are both located within the cleaning range of the automatic cleaning component, which is convenient for the automatic cleaning component to not only clean the photovoltaic power generation panel 25, but also ensure the cleaning of the first photosensitive sensor 26 and the second photosensitive sensor 27, so that the photosensitive component always has a high sensitivity to the light angle and light intensity.

[0030] The automatic cleaning assembly includes a first slideway 14 installed on the right side above the fixed plate 3 and a second slideway 21 installed on the left side. Figure 4 As shown, a drive motor 15 is fixedly mounted on one side of the first slideway 14 via a connecting rod 16, and the output end of the drive motor 15 is a lead screw 17 that passes into the interior of the first slideway 14. Figure 5 As shown, the first bearing 19 and the second bearing 20 are respectively installed at the ends of the upper and lower sides of the first slideway 14, and both ends of the lead screw 17 are connected to the center positions of the first bearing 19 and the second bearing 20, which is convenient for fixing the position of the lead screw 17 and also convenient for the smooth rotation of the lead screw 17.

A connecting plate 24 is connected and fixed between the first slide bar 18 and the second slide bar 23, and the first slide bar 18 can drive the second slide bar 23 to slide up and down together through the connecting plate 24 under the drive of the driving motor 15.

[0032] like Figure 2As shown, a cleaning motor 28 is fixedly mounted on the outer side of the second slider 23, and the output end of the cleaning motor 28 passes through the second slider 23 and is connected to a cleaning brush shaft 30 located at the bottom of the connecting plate 24. The cleaning motor 28 drives the cleaning brush shaft 30 to rotate at a high speed, so that dirt can be cleaned more quickly and efficiently. A positioning block 31 is provided at the bottom of the connecting plate 24 near the first slideway 14, and a third bearing 32 is installed in the positioning block 31. The inner end of the cleaning brush shaft 30 is connected to the third bearing 32, which can provide support for the end of the cleaning brush shaft 30, making the cleaning brush shaft 30 more stable, preventing the cleaning brush shaft 30 from being easily misplaced when used for a long time or cleaning some relatively heavy dirt, and effectively improving the durability of the cleaning brush shaft 30. The bottom of the cleaning brush shaft 30 is close to the upper surface of the photovoltaic power generation panel 25, which can ensure that the cleaning brush shaft 30 effectively cleans the photovoltaic power generation panel 25.

[0033] In addition, the first photosensor 26 and the second photosensor 27 are also within the length range on the upper and lower sides of the first slide 14 and the second slide 21, so that the cleaning brush shaft 30 can also clean the first photosensor 26 and the second photosensor 27. The controller 13 can be used to control the automatic cleaning component to perform timed cleaning or receive manual control signals for cleaning.

[0034] like Figure 1 As shown, the elevation angle adjustment assembly includes an electric telescopic rod 6 installed on the mounting plate 1 and a connecting block 4 connected to the bottom of the fixed plate 3. The connecting block 4 is movably connected to the upper end of the electric telescopic rod 6 via a second connecting shaft 5. The fixed plate 3 can be rotated around the first connecting shaft 2 by the extension and retraction of the electric telescopic rod 6, thereby realizing the adjustment of the placement angle of the fixed plate 3.

[0035] The electric telescopic rod 6 is installed on the mounting plate 1 at an angle, and when the electric telescopic rod 6 is fully extended, the fixing plate 3 can be in a vertical state, so that when the photovoltaic panel 25 and the first photosensor 26 and the second photosensor 27 are cleaned, the dirt above the fixing plate 3 can be cleaned more easily.

[0036] like Figure 1As shown, the direction adjustment component includes a support column 8 installed at the center position above the base 7, and a rotating shaft 9 is movably connected to the support column 8. The top of the rotating shaft 9 is fixedly connected to the bottom center position of the mounting plate 1, and a driven gear 10 is fixed on the outside of the rotating shaft 9. A rotating motor 11 fixed to the base 7 is installed on one side of the support column 8, and a driving gear 12 is connected to the output end of the rotating motor 11, and the driving gear 12 is meshed with the driven gear 10. The working state of the rotating motor 11 can be controlled by the controller 13, so that the rotating motor 11 drives the rotating shaft 9 to rotate, and then the photovoltaic power generation panel 25 on the mounting plate 1 rotates on the horizontal plane. Finally, the photovoltaic power generation panel 25 can always face the sun through the adjustment of the horizontal direction of the photovoltaic power generation panel 25 by the direction adjustment component and the adjustment of the placement angle of the photovoltaic power generation panel 25 by the elevation adjustment component, so as to ensure that it always has a high power generation efficiency.

[0037] When the solar power generation device with automatic cleaning and light chasing functions of the utility model is running, the first photosensitive sensor 26 and the second photosensitive sensor 27 on the upper and lower sides recognize the angle and light intensity of sunlight in real time, and send the collected information to the controller 13. After processing, the controller 13 controls the elevation adjustment component and the direction adjustment component to adjust the angle, so that the photovoltaic power generation panel 25 can always face the sun, ensuring that the photovoltaic power generation panel 25 has a high power generation efficiency. In addition, the program setting of the controller 13 can set the function of automatic cleaning component timing cleaning and manual control active cleaning. When the automatic cleaning component performs cleaning work, the electric telescopic rod 6 is fully extended, so that the fixed plate 3 is in a vertical state, and then driven by the driving motor 15, the first slider 18, the second slider 23 and the connecting plate 24 move up and down in the first slide 14 and the second slide 21, and the cleaning motor 28 drives the cleaning brush shaft 30 at the bottom of the connecting plate 24 to rotate at a high speed, which can effectively make the photovoltaic power generation panel 25, the first photosensitive sensor 26 and the second photosensitive sensor 27 be quickly cleaned, which is conducive to further improving the power generation efficiency of the photovoltaic power generation panel 25. After the cleaning is completed, the controller 13 controls the elevation adjustment component and the direction adjustment component to adjust the angle, and continues to face the sun to generate electricity efficiently.

[0038] Therefore, the utility model adopts the above-mentioned solar power generation device with automatic cleaning and light chasing functions, which can identify the light angle in real time and actively adjust the direction of the photovoltaic panel. It can also automatically clean the photovoltaic panel and photosensitive components, and has extremely high cleaning efficiency, so that the attached dirt can be cleaned quickly and effectively, ensuring the recognition accuracy of the photosensitive component, which is beneficial to improving the power generation efficiency of the photovoltaic panel.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that they can still modify or replace the technical solution of the utility model with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the utility model.
