Description

[0002] Photovoltaic power stations are a green energy source that is environmentally friendly and pollution-free. They do not generate noise or greenhouse gases during the power generation process and are therefore environmentally friendly. However, traditional photovoltaic power stations, especially those located in mountainous areas, are prone to dust accumulation due to long-term exposure. Due to their geographical location, they cannot be maintained in a timely manner, resulting in a significant drop in power generation. As the angle of sunlight changes over time, the power generation efficiency of photovoltaic power stations is reduced due to light problems. Traditional photovoltaic power stations are installed in a manner similar to a skylight, where the keel is installed first and then the photovoltaic glass panels are installed. This is not an integrated assembled installation, which has low installation efficiency.

A photovoltaic controller 8, a battery 9 and a main control board 14 are also provided on the ground. The photovoltaic panel assembly 1 is electrically connected to the battery 9 through the photovoltaic controller 8.

The photosensitive controller 20 can be arranged on the adjustment bracket assembly 2. The photosensitive controller 20 is electrically connected to the photosensitive element 19, the main control board 14, and the battery 9 respectively. Of course, the photosensitive controller 20 can also be integrated with the main control board 14 in the same box.

When the first two-dimensional coordinate is not located at the origin of the two-dimensional coordinate ( Figure 7 As shown), by calculating the difference between the first two-dimensional coordinate and the two-dimensional coordinate origin, the second two-dimensional coordinate is obtained, and the bracket assembly is controlled and adjusted according to the second two-dimensional coordinate to adjust the photovoltaic panel assembly 1 ( Figure 8 and Figure 9 As shown), the center position of the photovoltaic panel assembly 1 is located at the second two-dimensional coordinate ( Figure 8 As shown), during the adjustment process, the photovoltaic panel assembly 1 is not at a 90-degree angle to the sunlight ( Figure 8 As shown), adjust the bracket assembly again so that the isotherms of the temperature cloud map are like water ripples ( Figure 9 As shown) to ensure that the center of the photovoltaic panel assembly 1 is always located at the highest point of heat in the entire photovoltaic panel assembly 1.

[0034] The conversion of the second two-dimensional coordinates into the adjustment parameters required for adjusting the bracket assembly is a prior art and will not be described in detail here.

[0042] like Figure 4 As shown, the brush assembly 75 includes a brush 751, a brush seat 752, and a buffer 753. The brush 751 is fixed on the brush seat 752. A rod groove 741 is provided on the lower end surface of the walking rod 74. The groove rod 741 is arranged along the length direction of the walking rod 74. The brush seat 752 is fixed in the rod groove 741. The brush seat 752 is arranged along the length direction of the rod groove 741. Its length is adapted to the rod groove 741. The brush 751 extends from the rod groove 741 and is aligned with the surface of the photovoltaic panel assembly 1. Surface contact, specifically, limiting bosses 742 are provided on the groove walls on opposite sides of the rod groove 741, and a gap is provided between the limiting bosses 742 for the brush 751 to pass through, so that after the brush holder 752 is fixed in the rod groove 741, the brush 751 passes through the gap and contacts the surface of the photovoltaic panel 101, and the buffer 753 is provided in the slide groove 711 and abuts against the brush holder 752 and the upper end of the rod groove 741; preferably, the buffer 753 is a spring, which is arranged at intervals in the rod groove 741.

[0043] As an embodiment of the present invention, a vibrator (not shown in the figure) may be provided on part of the buffer member 753 to achieve a vibration effect of the brush and further improve the cleaning effect.

After the time is reached, the main control board 14 controls the water pump 21 to start and the inlet of the two-inlet and one-outlet solenoid valve 22 connected to the water pump 21 is connected, so that the nozzle 4 sprays high-pressure water and sprays it on the surface of the photovoltaic panel 101. At this time, the drive motor 73 is controlled to work, driving the walking rod 74 to move on the surface of the photovoltaic panel 101, sweeping water and dust to the water tank 3. After collecting sewage, the water tank 3 is filtered through the filter device 6, and the filtered water enters the water storage tank 5 for storage for the next recycling. The water tank 3 is also used for rainwater recovery. When the system is working, the photosensitive element 19 obtains light data and sends it to the photosensitive controller 20. The photosensitive controller 20 processes the light data and sends it to the main control board 14. The main control board 14 then calculates the tilt angle based on the processed light data, controls the hydraulic pump 13 and the opening amount of each solenoid valve to adjust the length of the telescopic support rod 11, thereby adjusting the tilt angle of the photovoltaic panel assembly 1 to increase the power generation of the photovoltaic panel assembly 1; when encountering low temperature weather, the temperature data of the temperature sensor 17 in the water tank 5 is sent to the main control board 14, and the main control board 14 selectively turns on the heating assembly 18 according to the preset to prevent the water in the water tank 5 from freezing.
