Description

Technical Field

[0001] The present invention generally relates to the field of solar energy, and in particular to a solar energy dust removal device capable of automatically removing dust from the surface of a solar cell. Background Art

[0002] my country is a major manufacturer of solar photovoltaic modules, with widespread adoption and favorable policies. With the proposal and implementation of my country's carbon peak and carbon neutrality goals, solar energy, as a major renewable energy source, has seen significant growth. However, a large number of photovoltaic panels in solar photovoltaic power plants are installed close to the ground, often on barren slopes in the wild. The panels have a relatively gentle slope, and windblown dust easily covers the panels' surfaces. This directly affects their light transmittance and significantly reduces the cells' photoelectric conversion efficiency. This dust, which previously improved the power generation efficiency of cell materials, is now weakened by this dust, resulting in direct economic losses for photovoltaic power plants. The dust accumulates continuously and must be removed promptly.

[0003] To remove dust from photovoltaic panels, manual dust removal is currently used, which is relatively inefficient and labor-intensive. Regarding dust removal using equipment, one technique involves installing a long robotic arm on a vehicle with a cleaning head mounted on the end. Specifically, the vehicle travels along the gaps between each row of photovoltaic panels, while the robotic arm, mounted on the vehicle, extends from one side and places the cleaning head over the panels, cleaning them as it moves. However, this method has the following problems:

[0004] First, the distance between adjacent rows of photovoltaic panels is typically very close, leaving insufficient space for vehicles. Even if a vehicle manages to squeeze in, it's difficult to maneuver and could easily run over or collide with the panels. Second, if the road is bumpy or impassable on a barren slope, while slopes are ideal for solar photovoltaic installations, they can also cause vehicles to overturn, making them unsuitable for operation. Furthermore, it's difficult for the driver to maintain a parallel cleaning head with the panel surface while the vehicle is moving, and varying depths of contact can easily cause squeezing, shaking, or damage to the panels. The initial investment in a vehicle is significant, as is the driver's fuel requirements.

[0005] Some previous plans involved installing scraping devices on solar panels and using rack and pinion transmission. However, the rack and pinion are prone to rust when exposed to the air, and require double guide rails. Whether the double guide rails can be installed parallel to the rack is very difficult, and has almost become a problem in the field of precision machinery. For photovoltaic panels working in the field, the manufacturing and installation costs are relatively high.

[0006] Another method is flushing with water pipes, but it consumes a lot of water. Many places do not have nearby water sources. In addition, water trucks are not easy to climb slopes and it is difficult to enter the photovoltaic power station array to work. When laying pipes, the water level pressure is also difficult to climb the slope, and flushing water is easy to splash mud on the ground onto the solar panels. Therefore, this method is suitable for sea, lakes and rivers.

[0007] In addition, there are also drones equipped with rotating brushes for dust removal, but they are difficult to operate, consume a lot of energy, and have low work efficiency. The weight and area of ​​the brush cannot be too large. They are effective for small photovoltaic panels on the roof, but are not suitable for large photovoltaic power stations.

[0008] Therefore, how to design and adopt a dust removal device with low cost, low maintenance, good adaptability and high reliability is a technical problem that needs to be solved urgently. Summary of the Invention

The bracket is fixed, the guide rail is set on the bracket, the guide member is installed on the support frame and movably cooperates with the guide rail, and the first winch is connected to the support frame through a cable.

[0030] like Figure 1 and Figure 2 As shown, the solar dust removal device of this embodiment is applied to a solar cell system 1, which includes a photovoltaic panel 11 and a support mechanism 12. The support mechanism 12 is used to support the photovoltaic panel 11, and the photovoltaic panel 11 is used to collect solar energy. The solar dust removal device of this embodiment includes a dust removal mechanism 2, a flip mechanism 3, and a horizontal movement mechanism 4. Among them, the dust removal mechanism 2 is used to remove dust from the surface of the photovoltaic panel 11, and the flip mechanism 3 is used to flip the dust removal mechanism 2 to facilitate maintenance and replacement of parts. The horizontal movement mechanism 4 is used to horizontally translate the dust removal mechanism 2 on the surface of the photovoltaic panel 11, thereby removing dust from the entire surface of the photovoltaic panel 11.

[0031] In this embodiment of the present invention, the dust removal mechanism 2 includes a frame 21, a driver 22, a rotating member 23 and a dust removal brush 24. The driver 22 is a motor mounted on the frame 21, and the rotating member 23 is a hub, which is connected to the driver 22 via a key 25. A bearing is provided between the frame 21 and the rotating member 23. The dust removal brush 24 is mounted on the rotating member 23, and the connection method can be adhesion or screw fixation to fit the surface of the photovoltaic panel 11. The direction of rotation of the dust removal brush 24 is to rotate the brushes in the forward direction. The dust removal brush 24 can be circular, annular or other shapes. The dust removal brush 24 is replaceable, and the diameter of the dust removal brush 24 when circular or annular is greater than the width of the photovoltaic panel 11 to achieve coverage.

[0032] In this embodiment of the present invention, the horizontal movement mechanism 4 includes a bracket 41, a guide rail 42, a support frame 43, a guide member 44, and a first hoist 45. The bracket 41 is fixed and can be connected to the support mechanism 12 or provided separately. The guide rail 42 is provided on the bracket 41 and located at the top. The guide member 44 is mounted on the support frame 43 and flexibly engages with the guide rail 42. Furthermore, the first hoist 45 is an electric hoist connected to the support frame 43 via a cable 46.

[0033] In this embodiment of the present invention, the guide member 43 includes a guide wheel that matches the guide rail 42. In this embodiment of the present invention, the guide rail 42 includes three guide surfaces, and there are three guide wheels, each of which matches one of the guide surfaces, thereby forming a clamping structure as a whole, ensuring that the support frame 43 does not separate from the guide rail 42.

[0034] In this embodiment of the present invention, the first hoist 45 is wound in conjunction with the first rope pulley 47. In this embodiment of the present invention, the cable 46 is connected to a rope block 48. One end of the rope block 48 is connected to the support frame 43, and the other end is hinged to the frame 21 via the rotating shaft 26.

One end of the traction rope 32 is connected to the frame 21, and the other end passes around the second sheave 33 before connecting to the second hoist 31. In this embodiment of the present invention, the second hoist 31 is a manual hoist. During the dust removal operation, when the dust removal brush 24 reaches the end of the photovoltaic panel 11, if further cleaning is required, the first hoist 45 is reversed, causing the rotating member 23 to rotate in the opposite direction, driving the dust removal brush 24 to clean the photovoltaic panel 11 again.

[0036] From the above technical solution, it can be seen that the advantages and positive effects of the solar dust removal device of the present invention are:

[0037] In the present invention, the driver 22 drives the rotating member 23, which in turn drives the dust removal brush 24 to rotate and remove dust from the surface of the photovoltaic panel 11. The horizontal movement mechanism 4 can also be used for translation, thereby removing dust from the entire surface of the photovoltaic panel 11. This fully automated dust removal system is highly efficient, labor-saving, and easy to market, making it a standard accessory for solar power generation.
