Description

Technical Field

[0001] The invention relates to the field of solar photovoltaic technology, and in particular to a solar photovoltaic component with a sunlight tracking system. Background Art

[0002] With the enhancement of human environmental awareness, as well as the advantages of cleanliness, safety, no noise, no electromagnetic radiation, simple structure, easy installation, etc., solar photovoltaic power generation has become a new energy source with great development potential. At present, solar photovoltaic technology and its application are in rapid development, and large-scale ground photovoltaic power stations and rooftop photovoltaic devices are also being widely used. In order to make more efficient use of solar energy, existing photovoltaic modules usually use corresponding sunlight tracking systems to achieve real-time tracking of light angles.

[0003] However, in the actual use of traditional solar photovoltaic modules with sunlight tracking systems, since most of the solar photovoltaic modules are installed outdoors, after long-term use, a large amount of dust is easily adhered to the surface of the photovoltaic panel, thereby blocking the surface of the photovoltaic panel, affecting the light utilization rate of the photovoltaic panel, and further affecting the photoelectric conversion efficiency. In addition, since there is no sunlight at night, the photovoltaic module does not work at night, but dust will continue to fall and accumulate, further affecting the light utilization rate of the photovoltaic panel when working; at the same time, especially in the weather conditions in the north, snowfall and dust weather conditions often occur. When snow or dust covers the surface of the photovoltaic panel, it not only seriously affects the light utilization rate, resulting in a decrease in the photoelectric conversion rate, but also, when the snow or dust accumulates too much, it will compress the photovoltaic module under the action of gravity, which is easy to deform or even damage its structure; in addition, when working in summer, when the temperature of the photovoltaic module is too high, the contact resistance of the photovoltaic panel will increase, thereby affecting its output performance, and ultimately resulting in a decrease in the photoelectric conversion efficiency, and the battery cells in the photovoltaic panel are also easily heated and expanded, causing certain safety hazards.

[0051] In the present invention, the cleaning mechanism 8 includes a cleaning frame 801, a cleaning frame 801 is fixedly connected between two moving blocks 604, a cleaning cotton 802 is installed in the cleaning frame 801, a drainage block 803 is fixedly connected to one side of the water tank 701, a plurality of drainage pipes 804 are arranged on the drainage block 803, a solenoid valve 806 is installed on the drainage pipe 804, and a plurality of filter screens 805 are arranged at the water inlet of the drainage pipe 804 inside the water tank 701. By setting the cleaning frame 801, the cleaning cotton 802, the drainage block 803, the drainage pipe 804, the filter screen 805 and the solenoid valve 806, according to the actual situation, after a lot of dust accumulates on the surface of the photovoltaic panel 203, the second motor 607 is driven to make the moving block 604 move. As the moving block 604 moves, the cleaning frame 801 will also move together, and then the cleaning cotton 802 thereon will move together. As the cleaning cotton 802 moves, the surface of the photovoltaic panel 203 will be wiped and cleaned. Furthermore, by controlling the solenoid valve 806 to open the solenoid valve 806, the water inside the water tank 701 will pass through the filter 805 into the drainage block 803, and then enter the drainage pipe 804, and then be discharged through the drainage pipe 804 to rinse the surface of the photovoltaic panel 203, thereby cooperating with the cleaning cotton 802 to facilitate the cleaning of the surface of the photovoltaic panel 203, avoid excessive dust accumulation, ensure the light utilization rate of the photovoltaic panel 203, and then ensure the photoelectric conversion efficiency.

[0052] Working principle: In actual operation, the installation frame 202 is installed between the two fixing plates 201, and then the photovoltaic panel 203 is installed on the installation frame 202. Through the photovoltaic panel 203, sunlight can be absorbed during operation, and then photoelectric conversion can be performed.

[0053] Furthermore, the photosensor body 3 will sense and analyze the light angle, and then transmit the sensing signal to the controller body 4, and then the first motor 502 will be powered on. Under the control of the controller body 4, the first motor 502 will rotate with the deflection of the light angle. The rotation of the first motor 502 will drive the mounting plate 1 to rotate together, and the support rod 503 will play the role of limiting support, thereby driving the photovoltaic components on the mounting plate 1 to rotate together, so that the photovoltaic components can achieve the corresponding sunlight tracking effect.

[0054] Next, water can be passed into the device when needed, and water can flow into the water tank 701 through one of the water pipes 702, and then flow out through another water pipe 702. In hot weather, when water enters the water tank 701, it will enter the multiple heat dissipation slots 704 through multiple through holes 706, and then flow out, so as to facilitate the absorption of heat emitted from the photovoltaic panel 203. Through the connecting pipe 705, water can flow between different heat dissipation slots 704, further enhancing the heat conduction efficiency and improving the heat dissipation efficiency, so as to facilitate the heat dissipation of the photovoltaic panel 203 in hot weather, improve the heat dissipation efficiency of the photovoltaic module, avoid the increase of the contact resistance of the photovoltaic panel 203, ensure its output performance, and finally ensure the normal photoelectric conversion efficiency. At the same time, it also reduces the thermal expansion of the battery cell in the photovoltaic panel 203 and reduces the corresponding safety hazards. Furthermore, in the rainy season, the cover 703 can be opened, and the rainwater can be collected through the opening of the water tank 701, thereby reducing the water consumption and being more environmentally friendly.

[0055] According to the actual situation, when it is dark or there is snow, dust and other weather conditions, the second motor 607 can be connected to the power supply, and the second motor 607 rotates to drive the screw rod 608 to rotate together. As the screw rod 608 rotates, it will drive the moving block 604 to continuously move inside the installation frame 202, and the screw rod protective cover connected to both sides of the moving block 604 will also fold and unfold accordingly, and the moving block 604 will also drive the connecting roller 605 to move together, and then the waterproof cover 603 will continue to unfold, and the rotating roller 602 will also rotate accordingly, and the spring 606 thereon will contract until the waterproof cover 603 completely covers the photovoltaic panel 203, so as to facilitate the photovoltaic panel 203 when needed. Shielding and protection reduce the accumulation of dust, thereby reducing the obstruction of the surface of the photovoltaic panel 203, thereby ensuring the light utilization rate of the photovoltaic panel 203, and then ensuring the photoelectric conversion efficiency. Furthermore, in snowy and dusty weather, when there is too much snow and dust on the surface of the waterproof cloth 603, the second motor 607 can be directly used to drive the waterproof cloth 603 to retract and wind it around the rotating roller 602 with the cooperation of the spring 606. In this process, the snow and dust accumulated on the waterproof cloth 603 will be automatically removed by the installation frame 202, and then the waterproof cloth 603 will be covered on the photovoltaic panel 203 again, thereby reducing the pressure on the photovoltaic panel 203 and avoiding its structural deformation or even damage.

[0056] Furthermore, when a lot of dust accumulates on the surface of the photovoltaic panel 203, the moving block 604 is driven by the second motor 607 to move, and as the moving block 604 moves, the cleaning frame 801 is also driven to move together, and then the cleaning cotton 802 thereon is driven to move together. As the cleaning cotton 802 moves, the surface of the photovoltaic panel 203 is wiped and cleaned. Furthermore, by controlling the solenoid valve 806 to open the solenoid valve 806, the water inside the water tank 701 will pass through the filter 805 into the drainage block 803, and then enter the drain pipe 804, and then be discharged through the drain pipe 804 to rinse the surface of the photovoltaic panel 203, thereby cooperating with the cleaning cotton 802 to facilitate the cleaning of the surface of the photovoltaic panel 203, avoid excessive dust accumulation, ensure the light utilization rate of the photovoltaic panel 203, and then ensure the photoelectric conversion efficiency.
