[0002] There are two common types of existing solar cleaning devices. One is a cleaning robot for cleaning the panel surface, as shown in CN109317452A, and the other is a brushing mechanism for the panel surface, as shown in CN112769388B. Both types of solar cleaning devices have the following problems in application:

[0003] 1. When the cleaning robot is used, each robot can only process one solar panel at a time. When facing solar panels arranged in pieces, the cleaning robot needs to clean them one by one, which has low cleaning efficiency. Alternatively, a cleaning robot is arranged separately for each solar panel, which is costly.

[0004] 2. The scrubbing mechanism can only be installed on a corresponding solar panel. When facing solar panels arranged in pieces, a scrubbing mechanism needs to be arranged on each piece, and the cleaning cost is too high.

[0005] 3. Regardless of the above, a solar panel is usually required as the installation base, which increases the installation burden of a single solar panel. Utility Model Content

[0036] Embodiment 1 provides an automatic solar panel cleaning device, which uses a solar panel 1 as a mounting base, saving installation space, facilitating the installation of cleaning equipment, and assisting the installation of solar panels 1, acting as a connector;

[0037] The device uses a motor 8 to provide driving force, and drives the rotating shaft 6 to rotate through the transmission component 7. The rotating shaft 6 rotates on the mounting plate 3 through the bearing 5, thereby driving the brush plate 9 to rotate synchronously. At this time, the bristles 10 brush the surface of the solar panel 1. While brushing, water can be supplied through the water supply component 11. The water enters the brush plate 9 through the rotating shaft 6 and is sprayed out through the installation position of the bristles 10. Brushing is performed while spraying, thereby improving the cleaning force and ensuring the cleaning effect.

[0038] As a preferred embodiment 2, the mounting plate 3 is arranged at adjacent positions of four solar panels 1, the four corners of the mounting plate 3 correspond to the solar panels 1 one by one, and the four corners of the mounting plate 3 are respectively detachably fixed with the bottom of the corresponding solar panel 1 through fasteners 4. This facilitates installation, increases the number of solar panels 1 covered by cleaning, and facilitates the fixing of auxiliary solar panels 1.

[0039] As a preferred embodiment 3, the rotating shaft 6 and the brush plate 9 are both hollow structures, and the middle position of the rotating shaft 6 and the brush plate 9 forms a linkage and is connected with the brush plate 9, ensuring that the rotating shaft 6 drives the brush plate 9 to rotate, and the brush plate 9 forms a water spray through the installation place of the bristles 10 to ensure spraying and brushing at the same time.

[0040] Preferably, the rotating shaft 6 and the brush plate 9 are integrally formed for easy use.

[0041] As a preferred embodiment 4, the rotation range of the brush plate 9 at least covers the adjacent solar cell panels 1, thereby ensuring the brushing effect.

In the conventional cleaning mode, the solenoid valve 1102 is opened, and water is supplied through the water storage barrel 1104. After the water pump 1103 is pressurized, it enters the rotating shaft 6 through the rotary joint 1101, and finally enters the brush plate 9 and is sprayed out through the installation position of the bristles 10, completing the operation of brushing and rinsing.

[0044] As a preferred embodiment 7, a controller 13 is provided on the outer side of the water storage barrel 1104, and the motor 8, the solenoid valve 1102 and the water pump 1103 are all linked with an external control device through the controller 13.

The raindrop sensor 12 is exposed from the gap 2 between the solar panels 1, and the sensing end of the raindrop sensor 12 forms an inductive match with the rainwater. The raindrop sensor 12 forms a linkage match with the motor 8 through the controller 13. The raindrop sensor 12 detects whether it is raining. When it is raining, the water supply component 11 is not turned on, and only the motor 8 is started to use the rainwater for brushing. When the rain stops, the motor 8 returns to the initial position and stops rotating, saving cleaning resources.

[0047] When the motor 8 is in the initial position, the brush plate 9 is parallel to and overlaps with one of the gaps 2, ensuring that the brush plate 9 does not hinder the normal use of the solar panel 1 when cleaning is not required.

[0051] During conventional cleaning, the device uses the motor 8 to provide driving force, drives the rotating shaft 6 to rotate through the transmission component 7, and the rotating shaft 6 rotates on the mounting plate 3 through the bearing 5, thereby driving the brush plate 9 to rotate synchronously. At this time, the bristles 10 scrub the surface of the solar panel 1, and water can be supplied through the water supply component 11 while scrubbing.

If rain is detected, the controller 13 automatically turns on the motor 8 for scrubbing, using rainwater for scrubbing and storing rainwater in the water storage barrel 1104 for the next cleaning. When the rain stops, the cleaning is stopped, saving resources and realizing intelligent cleaning.
