[0002] Solar panels are devices that can directly convert sunlight into electrical energy. They consist of multiple solar cells, also known as photovoltaic cells. Solar panels are usually made of silicon materials and convert sunlight into DC electricity through the photoelectric effect. The working principle of solar panels is based on the photovoltaic effect. When sunlight shines on solar panels, the semiconductor material (usually silicon) in the cell absorbs the energy of photons, causing its internal electrons to jump to a higher energy level.

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0039] In one embodiment, reference Figure 1-8 A self-expanding solar cell panel comprises a first back plate 1 and a second back plate 2, wherein the first back plate 1 and the second back plate 2 are connected together by hinges, a panel body 3 is installed on the surface of the first back plate 1 and the second back plate 2, a bottom plate 4 is arranged below the first back plate 1 and the second back plate 2, a driving part 5 for driving the first back plate 1 and the second back plate 2 to unfold is installed on the surface of the bottom plate 4, and further comprises: an adjusting component 6, which is arranged on the bottom surface of the first back plate 1 and the second back plate 2, one end of which is connected to the output end of the driving part 5, and is used to adjust the illumination angle of the panel body 3; a protective component 7, which is symmetrically arranged on the surface of the first back plate 1 and the second back plate 2, and is used to block and protect the contact part of the first back plate 1 and the second back plate 2 when they are folded; a cleaning component 8, which is arranged on the surface of the bottom plate 4, and its end is extended and installed on the side surface of the first back plate 1 and the second back plate 2, and is used to clean the dust accumulated on the surface of the panel body 3.

[0040] According to the scheme of the present invention, when in use, the bottom plate 4 provided on the device is pre-installed at a suitable position to limit its position, and the first back plate 1 and the second back plate 2 are driven to unfold by starting the driving part 5. The adjustment component 6 provided on the first back plate 1 and the second back plate 2 is used to adjust and limit the unfolding angle of the first back plate 1 and the second back plate 2 to make them V-shaped, and the light at the battery panel body 3 is refracted and reflected to the corresponding battery panel body 3 to fully absorb the light energy, thereby improving the photoelectric conversion efficiency of the device. When the device is stored, the power source generated by the operation of the adjustment component 6 drives the protection component 7 to run synchronously, and the contact part between the first back plate 1 and the second back plate 2 when stored is protected and buffered, so as to prevent the first back plate 1 and the second back plate 2 from contacting each other when they are installed on the battery panel body 3 when stored, and avoid friction on the battery panel body 3 during transportation and movement. The anti-reflective coating covered is damaged, thereby affecting the illumination effect of the device during subsequent use, causing light scattering, reducing the light energy absorption of the device, and affecting its power generation efficiency. At the same time, it does not affect the folding of the first back plate 1 and the second back plate 2, and has a good protective effect on them. When stored and folded, dust and foreign matter are easily dropped on the surface of the solar panel body 3 during use, covering the surface of the solar panel body 3. When stored, the power generated by the operation of the adjustment component 6 drives the cleaning component 8 to operate, so that it generates airflow, and the airflow is transported to the first back plate 1 and the second back plate 2, thereby blowing and cleaning the surface of the solar panel body 3 installed thereon, thereby eliminating the trouble of manual cleaning and facilitating the next use. At the same time, it can avoid the accumulation of dust and foreign matter on the solar panel body 3 to block the irradiation of light, further improving the photoelectric conversion efficiency of the device and ensuring the maximum reception of sunlight.

[0041] It should be noted that the driving unit 5 can be driven by a driving source such as a linear drive.

[0042] In a preferred embodiment, referring to Figure 4 and Figure 6 The adjustment component 6 includes a mounting seat 61 fixed at the output end of the driving part 5, a connecting plate 62 is installed on the top of the mounting seat 61, and the surface of the connecting plate 62 is rotatably connected to two rotating rods 63 through a pin shaft, and the ends of the two rotating rods 63 are rotatably provided with a concave plate 64 through a pin shaft, and a T-shaped slider 65 is fixed on the top of the concave plate 64, and the T-shaped slider 65 is slidably connected in the T-shaped slide groove 66, and the T-shaped slide groove 66 is symmetrically opened on the bottom surfaces of the first back plate 1 and the second back plate 2, and one side of the two T-shaped sliders 65 are fixed with extrusion springs 67, and the extrusion springs 67 are fixed in the T-shaped slide groove 66.

[0043] With such a solution, when the driving unit 5 is started, the mounting seat 61 is driven to move upward, and the T-shaped slider 65 slides inside the T-shaped slide groove 66, so that the first back plate 1 and the second back plate 2 are respectively rotated to both sides to realize the unfolding operation. At this time, the first back plate 1 and the second back plate 2 are limited by the vertical upward force of the driving unit 5, and the rotation angles are synchronized, so that the first back plate 1 and the second back plate 2 are in a V shape. Considering that the irradiation angles of sunlight are different during use, a sensor is installed on the device to detect the irradiation angle of light, and then the unfolding angles of the first back plate 1 and the second back plate 2 are controlled by the driving unit 5. To better adapt to the irradiation of sunlight, when the sunlight irradiates the solar panel body 3 on the first back plate 1, the refracted sunlight can be reflected to the solar panel body 3 installed on the second back plate 2 by utilizing the refraction of sunlight, thereby fully absorbing and utilizing the sunlight, thereby improving the power generation effect of the device. When the first back plate 1 and the second back plate 2 are unfolded, through the setting of the extrusion spring 67, its elastic rebound can be utilized to extrude the T-shaped slider 65 to move, so that the first back plate 1 and the second back plate 2 are smoother when unfolding, and at the same time, it does not affect the storage operation of the first back plate 1 and the second back plate 2, and the operation is more stable.

[0044] In a preferred embodiment, referring to Figure 3 , Figure 6 and Figure 7 The protection component 7 includes a fixing plate 71 fixed on the side surface of the concave plate 64, and push rods 72 are fixed on the surfaces of the two fixing plates 71. The ends of the push rods 72 are connected to pistons 73, and the pistons 73 are slidably connected in connecting tubes 74. The two connecting tubes 74 are respectively installed on the bottom surfaces of the first back plate 1 and the second back plate 2. The ends of the connecting tubes 74 are connected to air pipes 75, and the ends of the air pipes 75 are fixed with strip air bags 76. The strip air bags 76 are installed on mounting plates 77. The two mounting plates 77 are respectively fixed on the surfaces of the first back plate 1 and the second back plate 2.

[0045] With such a scheme, when storing, the concave plate 64 moves to drive the push rod 72 on one side to move synchronously, and then the piston 73 at the end of the push rod 72 slides inside the connecting tube 74, squeezing the air inside the connecting tube 74, and the connecting tube 74 is connected to the strip air bag 76 through the air supply pipe 75. When the squeezed air is transported to the strip air bag 76 through the air supply pipe 75, it expands. In this way, when the first back plate 1 and the second back plate 2 are stored and folded, the contact part of the first back plate 1 and the second back plate 2 is blocked and buffered by the strip air bag 76, so as to avoid the contact between the first back plate 1 and the second back plate 2 and the battery panel body 3 installed thereon when the first back plate 1 and the second back plate 2 are folded and stored. In this way, vibration and friction occur during the moving and carrying process, causing wear of the anti-reflection coating applied on the battery panel body 3, thereby affecting the subsequent light absorption of the battery panel body 3, and at the same time, it has a good protective effect on the battery panel body 3 on the first back plate 1 and the second back plate 2, prolonging its service life and avoiding the occurrence of light scattering.

[0046] In a preferred embodiment, referring to Figure 2 , Figure 4 and Figure 8 The cleaning assembly 8 includes a support plate 81 fixed on the side surface of the mounting seat 61, a lower pressure rod 82 is fixed to the bottom of the support plate 81, an extrusion plate 83 is installed at the bottom of the lower pressure rod 82, a square air bag 84 is attached to the bottom of the extrusion plate 83, the square air bag 84 is installed on the surface of the bottom plate 4, one end of the square air bag 84 is connected to a delivery hose 85, an air collecting plate 86 is fixed to the end of the delivery hose 85, the two air collecting plates 86 are respectively installed on the surfaces of the first back plate 1 and the second back plate 2, and a nozzle 87 is installed on the side surface of the air collecting plate 86.

[0047] With such a solution, when storing, the mounting seat 61 moves vertically downward, and the support plates 81 arranged on both sides of the mounting seat 61 move synchronously, so that the extrusion plate 83 squeezes the square air bag 84, and the air inside the square air bag 84 is squeezed and transported to the air collecting plate 86 through the conveying hose 85, and then sprayed out from multiple nozzles 87, wherein two adjacent nozzles 87 are staggered and arranged, and the spraying angles are 15° and 45°, so that the range of the sprayed air flow is wider, thereby improving the cleaning effect of the device, and the air collecting plate 86 is arranged at one side of the first back plate 1 and the second back plate 2, and the air jet is sprayed towards the other side for cleaning, so that dust and foreign matter are blown off, eliminating the trouble of manual cleaning, and such a design can prevent dust from blocking the irradiation of light, further improving the efficiency of photoelectric conversion,

[0048] In a preferred embodiment, referring to Figure 1-8One end of the first back plate 1 and the second back plate 2 are both rotatably provided with a connecting piece 9 through a pin shaft, and a limiting plate 10 is installed on the end of the connecting piece 9. The end of the limiting plate 10 is rotatably connected with the bottom plate 4 through a pin shaft. An opening 11 is provided on the surface of the limiting plate 10, and a base 12 is installed on the bottom surface of the bottom plate 4. The base 12 does not contact the driving part 5. A fixing plate 13 is installed on the bottom surface of the base 12, and a baffle 14 is provided on the surface of the fixing plate 13. The side surfaces of the two square airbags 84 are both fitted with baffles 14, and the baffles 14 are installed on the surface of the bottom plate 4.

[0049] By adopting such a scheme, the setting of the limit plate 10 can play a role in limiting the movement of the first back plate 1 and the second back plate 2. At the same time, when stored, the two side surfaces of the first back plate 1 and the second back plate 2 in the stored state can be protected. The opening 11 opened on the surface of the limit plate 10 prevents the cleaning component 8 from contacting the limit plate 10 during operation, so that the cleaning component 8 can run more smoothly. Through the setting of the baffle 14, the two side surfaces of the square airbag 84 are limited, making the structure more stable. During installation, the fixing plate 13 and the baffle 14 are conveniently matched with bolts to install it on the power generation equipment.

[0050] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
