DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1

[0035] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a solar photovoltaic power generation device includes a base plate 1, two support plates 2 and a plurality of solar panels 10, characterized in that: the two support plates 2 are symmetrically fixed to the upper end of the base plate 1, and the plurality of solar panels 10 are installed between the two support plates 2;

[0036] From the above, it can be basically known that the two support plates 2 and the base plate 1 can form a basic frame supporting the support unit 4, the fixing rod 11, the protective focusing unit 8 and the driving unit 7, and the basic frame can provide a platform for the operation of the protective focusing unit 8, the support unit 4 and the driving unit 7.

[0037] The solar cell panel 10 mentioned above is a device that absorbs sunlight and converts solar radiation energy directly or indirectly into electrical energy through the photoelectric effect or the photochemical effect. The main material of most solar cell panels 10 is "silicon". Compared with ordinary batteries and rechargeable batteries, solar cells are more energy-saving and environmentally friendly green products.

[0038] Specifically, in order to allow the solar panel 10 to receive sunlight during use, refer to Figure 1 and Figure 2 In this embodiment, a fixing plate 6 is provided on one side of one of the support plates 2 away from the solar panel 10, and a driving unit 7 for adjusting the angles of the plurality of solar panels 10 is provided on the upper end of the fixing plate 6. A fixing rod 11 is fixed between the opposite surfaces of the two support plates 2, and a supporting unit 4 is rotatably arranged on the outer surface of the fixing rod 11. The solar panel 10 is mounted on the supporting unit 4, and the driving unit 7 adjusts the angle of the solar panel 10 by driving the supporting unit 4. A triangular connecting plate 12 is provided in the middle of the outer surface of the fixing rod 11, and a circular supporting plate 3 for supporting is provided at the lower end of the triangular connecting plate 12. The lower end of the triangular connecting plate 12 is fixed to the middle of the upper end of the circular supporting plate 3, and a plurality of top rods 5 are provided in a circular array at the front of the upper end of the circular supporting plate 3. A protective focusing unit 8 for covering the supporting unit 4 is provided on the fixing rod 11.

[0039] During the installation process, the device needs to be installed facing the direction of sunlight so that sunlight can directly irradiate the outside of the supporting unit 4 and the inside of the protective focusing unit 8.

[0040] As can be seen from the above, in a normal use state, the support unit 4 is in an open state, and the protective focusing unit 8 will not shield the support unit 4. On the contrary, through the structure of the protective focusing unit 8, all the sunlight irradiated from the outside into the protective focusing unit 8 can be reflected to the outer surface 10 installed outside the support unit 4. At the same time, the arc structure of the support unit 4 can also increase the contact area between the solar panels 10 and the sunlight, thereby increasing the power generation of the solar panels 10.

[0041] When the device is not in use, the support unit 4 and the protective focusing unit 8 can be rotated by operating the driving unit 7, so that the support unit 4 can be folded under the cover of the protective focusing unit 8. By covering the support unit 4 with the protective focusing unit 8, the integrity of the solar panel 10 can be protected, thereby increasing the service life of the solar panel 10.

[0042] Specifically, in order to facilitate the folding and recycling of the support unit 4, refer to Figure 3 In this embodiment, the support unit 4 includes an arc-shaped support plate 41, the lower end of the arc-shaped support plate 41 is fixedly connected to the upper ends of a plurality of push rods 5, the inner surface of the arc-shaped support plate 41 is rotatably connected to the arc-shaped support plate 42, the inner surface of the arc-shaped support plate 42 is rotatably connected to the arc-shaped support plate 3 43, the inner surface of the arc-shaped support plate 3 43 is rotatably connected to the arc-shaped support plate 4 44, and a sealing plate 45 is fixed to the end of the arc-shaped support plate 44 away from the arc-shaped support plate 41, and the ends of the sealing plate 45, the arc-shaped support plate 41, the arc-shaped support plate 2 42, the arc-shaped support plate 3 43 and the arc-shaped support plate 4 44 away from the driving unit 7 are all rotatably connected to the outer surface of the fixing rod 11, and the driving unit 7 drives the arc-shaped support plate 4 44 to rotate.

[0043] As can be seen from the above, the outer surfaces and inner surfaces of the arc support plate 1 41, the arc support plate 2 42, the arc support plate 3 43 and the arc support plate 4 44 are all arc-shaped structures. Since the volumes of the arc support plate 1 41, the arc support plate 2 42, the arc support plate 3 43 and the arc support plate 4 44 are reduced successively, when the arc support plate 1 41, the arc support plate 2 42, the arc support plate 3 43 and the arc support plate 4 44 are stored, the arc support plate 1 41, the arc support plate 2 42, the arc support plate 3 43 and the arc support plate 4 44 can be rotated respectively, so that the arc support plate 4 44 is in the inner cavity of the arc support plate 3 43, the arc support plate 3 43 is in the inner cavity of the arc support plate 2 42, and the arc support plate 2 42 is in the inner cavity of the arc support plate 1 41, and finally the end of the arc support plate 1 41 away from the circular support plate 3 can be covered by the sealing plate 1 45.

[0044] Further, in order to ensure the stability of the support unit 4 in the unfolded state, refer to Figure 3 In this embodiment, a plurality of top rods 451 for supporting the sealing plate 1 45 are provided in an annular array at the lower end of the sealing plate 1 45;

[0045] When the support unit 4 is in the expanded state, the angle between the lower end of the arc-shaped support plate 41 and the lower end of the arc-shaped support plate 44 is 180°. Through a plurality of top rods 451 and a plurality of top rods 5, the lower end of the sealing plate 45 and the lower end of the arc-shaped support plate 41 can be respectively supported by cooperating with the circular support plate 3 to support the support unit 4 as a whole, thereby ensuring the stability of the support unit 4 in the expanded state.

[0046] Specifically, in order to facilitate the unfolding and storage of the support unit 4, refer to Figure 3 and Figure 4 In this embodiment, an installation groove 411 for installing the solar cell panel 10 is provided on the outer surface of the arc support plate 41, an arc-shaped limiting plate 412 is provided at the rear of the inner surface of the arc support plate 41, and an installation groove 421 for installing the solar cell panel 10 is provided on the outer surface of the arc support plate 42. An arc-shaped connecting plate 422 used in conjunction with the arc-shaped limiting plate 412 is provided at the front of the outer surface of the arc support plate 42, and an arc-shaped limiting plate 423 is provided at the rear of the inner surface of the arc support plate 42.

[0047] For further information, see Figure 3 and Figure 4In this embodiment, the outer surface of the arc support plate 43 is provided with a mounting groove 431 for mounting the solar cell panel 10, the front of the outer surface of the arc support plate 43 is provided with an arc connecting plate 432 used in conjunction with the arc limiting plate 423, the rear of the inner surface of the arc support plate 43 is provided with an arc limiting plate 433, the outer surface of the arc support plate 44 is provided with a mounting groove 441 for mounting the solar cell panel 10, and the front of the outer surface of the mounting groove 441 is provided with an arc connecting plate 442 used in conjunction with the arc limiting plate 433.

[0048] Under normal circumstances, the arc-shaped connecting plate 442 is slidably connected to the inner surface of the arc-shaped support plate 3 43, and the arc-shaped limiting plate 3 433 blocks the arc-shaped connecting plate 442, thereby preventing the arc-shaped support plate 44 from separating from the arc-shaped support plate 3 43 during the rotation process;

[0049] The arc-shaped connecting plate 3 432 is slidably connected to the inner surface of the arc-shaped supporting plate 2 42, and the arc-shaped limiting plate 2 423 blocks the arc-shaped connecting plate 3 432, thereby preventing the arc-shaped supporting plate 3 43 from being separated from the arc-shaped supporting plate 2 42 during the rotation process;

[0050] The arc-shaped connecting plate 2 422 is slidably connected to the inner surface of the arc-shaped supporting plate 1 41, and the arc-shaped limiting plate 1 412 blocks the arc-shaped connecting plate 2 422, thereby preventing the arc-shaped supporting plate 2 42 from being separated from the arc-shaped supporting plate 1 41 during the rotation process;

[0051] From the above, it can be seen that when the driving unit 7 drives the arc support plate four 44 to rotate, the arc support plate four 442 and the arc connection plate two 422, the arc connection plate three 432 and the arc limit plate two 423, and the arc connection plate two 422 and the arc limit plate one 412 can make the arc support plate four 44 rotate first. When the rotation angle of the arc support plate four 44 is 45°, the arc support plate three 43 is driven to start rotating through the mutual cooperation between the arc connection plate four 442 and the arc limit plate three 433. When the rotation angle of the arc support plate four 44 is 90°, the arc support plate two 42 is driven to start rotating through the mutual cooperation between the arc connection plate three 432 and the arc limit plate two 423, until the unfolding operation is completed when the rotation angle of the arc support plate four 44 is 135°.

[0052] Embodiment 2

[0053] This embodiment optimizes the protective focusing unit 8 on the basis of the first embodiment so that it can reflect sunlight, so that the several solar cell panels 10 located on the arc support plate 1 41, the arc support plate 2 42, the arc support plate 3 43 and the arc support plate 4 44 can all be irradiated by sunlight, thereby achieving the purpose of improving the power generation efficiency.

[0054] Specifically, to achieve the above purpose, refer to Figure 5 and Figure 8 In this embodiment, the protective focusing unit 8 includes a hemispherical shell 81 rotated on the outer surface of the fixed rod 11, an arc-shaped vertical plate 83 is provided at the rear of the upper end of the hemispherical shell 81, and a plurality of water outlet holes 82 communicating with the outer surface are opened in a rectangular array on the right part of the inner surface of the hemispherical shell 81;

[0055] The plurality of water outlet holes 82 can prevent rainwater from being pushed into the inner cavity of the hemispherical housing 81 .

[0056] For further information, see Figure 5 In this embodiment, the inner surface of the hemispherical shell 81 and the inner surface of the arc-shaped vertical plate 83 are coated with reflective materials;

[0057] The reflective material mentioned above is mercury paint in this embodiment, which is evenly sprayed on the inner surface of the hemispherical shell 81 and the arc-shaped upright plate 83. The arc-shaped structure of the hemispherical shell 81 and the arc-shaped upright plate 83 can fully reflect the sunlight, so that the sunlight can be completely covered on the outer surface of the plurality of solar cell panels 10, thereby reducing the influence of the sun angle on the device during the power generation process;

[0058] When the device is not in use, the driving unit 7 can drive the hemispherical shell 81 and the water outlet 82 to rotate, and the hemispherical shell 81, the circular support plate 3 and the sealing plate 45 cooperate with each other to seal the support unit 4 and the plurality of solar cell panels 10, thereby protecting the two and extending their service life.

[0059] Embodiment 3

[0060] This embodiment adds a driving unit 7 on the basis of the second embodiment, which can adjust the angle state of the protective focusing unit 8 and the unfolding state of the support unit 4 respectively. The driving unit 7 is manually operated to achieve the purpose of unfolding and storing the support unit 4 and the solar cell panel 10.

[0061] Specifically, to achieve the above purpose, refer to Figure 6 and Figure 7 In this embodiment, the driving unit 7 includes a housing 71 disposed at the upper end of the fixing plate 6, a worm 72 is disposed at the rear of the inner cavity of the housing 71, a handle 73 is disposed at the upper end of the worm 72, and the handle 73 is located outside the housing 71, a driving structure 74 for driving the hemispherical housing 81 to rotate is disposed at the left part of the inner cavity of the housing 71, and a driving structure 75 for driving the arc support plate 44 to rotate is disposed at the right part of the inner cavity of the housing 71;

[0062] As can be seen from the above, under the premise of the protection and fixation of the housing 1 71, the purpose of rotating the worm 72 is achieved by rotating the handle 73;

[0063] The rotation of the worm 72 drives the driving structure 1 74 and the driving structure 2 75 to run in the opposite direction, thereby driving the hemispherical shell 81 and the arc support plate 4 44 to run in the opposite direction, so that the protective focusing unit 8 for protecting the supporting unit 4 can be evacuated while the supporting unit 4 is unfolded.

[0064] For further information, see Figure 6 and Figure 7 In this embodiment, the driving structure 74 includes a connecting column 741 fixed to the rear part of the inner cavity of the outer shell 71 and a connecting shell 744 fixed to the front part of the inner cavity of the outer shell 71. The left part and the middle part of the outer surface of the connecting column 741 are respectively provided with a gear 1 743 and a worm wheel 742 meshing with the worm 72, and the right part of the outer surface of the connecting shell 744 is provided with a gear 2 745 meshing with the gear 1 743.

[0065] For further information, see Figure 6 and Figure 7 In this embodiment, the driving structure 2 75 includes a pulley 1 751 fixed to the right end of the connecting column 741, and a connecting rod 752 is provided in the inner cavity of the connecting shell 744. The left end of the connecting rod 752 successively passes through the right part of the outer surface of the arc support plate 1 41, the arc support plate 2 42, the arc support plate 3 43 and the arc support plate 4 44, and extends to the left part and is rotatably connected to the right end of the fixed rod 11. The right end of the connecting rod 752 is provided with a pulley 2 754, and the outer surface of the pulley 2 754 and the outer surface of the pulley 1 751 are commonly wound with a transmission belt 753, and the left part of the outer surface of the connecting rod 752 is fixedly connected to the arc support plate 4 44.

[0066] As can be seen from the above, when the worm 72 is rotated, the worm wheel 742, gear 1 743 and pulley 1 751 can be driven by the worm 72 to rotate synchronously under the action of the connecting column 741, and the meshing relationship between gear 1 743 and gear 2 745 can make gear 2 745 rotate in the opposite direction, thereby driving the connecting shell 744 to rotate synchronously in the opposite direction under the support and fixation of the outer shell 1 71. The end of the connecting shell 744 away from the outer shell 1 71 is fixedly connected to the outer surface of the hemispherical outer shell 81, so the hemispherical outer shell 81 and the arc-shaped vertical plate 83 will rotate synchronously with the rotation of the connecting shell 744;

[0067] In combination with the above, under the connecting action of the transmission belt 753, the rotation directions of the pulley 2 754 and the pulley 1 751 are the same, and the rotation directions of the connecting rod 752 and the connecting shell 744 are opposite. Since the end of the connecting rod 752 away from the pulley 2 754 passes through the inner cavity of the connecting shell 744 and is fixedly connected to the front surface of the outer surface of the arc support plate 4 44, when the worm 72 rotates, the arc support plate 4 44 and the hemispherical shell 81 have opposite rotation directions, thereby achieving the purpose of unfolding and storing the support unit 4 and the solar cell panel 10 by manually operating the drive unit 7.

[0068] It should be noted that the specific installation method of the solar panel 10, the connection method of the oil circuit and the control method used in the above-mentioned embodiment 1 are all conventional designs and will not be elaborated in detail in the present invention.

[0069] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
