[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be further described in detail below with reference to specific examples and accompanying drawings.

[0030] It should be noted that all uses of "first" and "second" in the embodiments of this utility model are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of this utility model. Subsequent embodiments will not explain this in detail.

[0031] In traditional spherical solar modules, solar panels are distributed in a planar manner on flat solar panels. The flat solar panels are at a certain angle, usually 20° to 55°. Because the solar panels are arranged in a planar manner, the power generation efficiency per unit area is not high, resulting in a lot of wasted space. At the same time, due to the planar arrangement, dust easily accumulates on the surface of the solar panels, which is not conducive to maintenance.

[0032] Figure 2 This is a schematic diagram of the principle of a spherical solar power generation device disclosed in an embodiment of the present invention; Figure 3 This is a schematic diagram of a spherical solar panel disclosed in an embodiment of the present invention.

[0033] like Figures 2-3 As shown, some embodiments of this utility model disclose a spherical solar power generation device. The spherical solar power generation device includes a spherical solar panel 1, a battery pack 2, and a controller 3. The controller 3 connects the spherical solar panel 1 and the battery pack 2, and is used to store the electrical energy converted by the spherical solar panel 1 into the battery pack 2. The spherical solar panel 1 includes a multi-faceted spherical support 11 and solar panels 12 mounted on the multi-faceted spherical support 11. By using the spherical solar panel 1, the planar solar panels are transformed into a three-dimensional spatial arrangement using a multi-faceted spherical support, improving the power generation efficiency per unit area and reducing dependence on land area.

[0034] Specifically, such as Figure 2 In the schematic diagram of the spherical solar power generation device shown, under sunlight, the spherical solar module 1 converts solar energy generated by the sun into electrical energy, and then the controller 3 stores the electrical energy in the battery pack 2.

[0035] Battery pack 2 is an independent and reliable operating power source, unaffected by AC power supply. Even in the event of a power outage or busbar short circuit, it can still ensure continuous and reliable operation. The battery has stable voltage and large capacity, making it suitable for various complex relay protection and automatic devices, as well as for the operation of various circuit breakers.

[0036] The controller 3 is electrically connected to the spherical solar assembly 1 and the battery pack 2, or the controller 3 is communicatively connected to the spherical solar assembly 1 and the battery pack 2.

[0037] The spherical solar assembly 1 is a space truss structure, which increases the area of the solar panel per unit of floor space and improves the power generation efficiency per unit of area.

[0038] As shown in FIG. 1, in some embodiments, the spherical solar power generation device further comprises a DC / AC inverter 4 electrically connected to an AC load 5 and a DC load 6 for transmitting electric energy to the AC load 5 or the DC load 6. Figures 2-3

[0039] Specifically, the DC / AC inverter 4 comprises a DC power supply for providing a DC input voltage, a converter circuit connected to the DC power supply for converting the DC input voltage into an AC signal for driving the load, and a control circuit connected to the converter circuit for setting the frequency of the AC signal. The control circuit can also operate the DC / AC inverter 4 in a fixed frequency mode and a variable frequency mode.

[0040] The DC / AC inverter 4 comprises two output terminals, one connected to the AC load 5 and the other connected to the DC load 6. It can select one of the outputs to provide electric energy, and of course it can also provide electric energy to both loads at the same time.

[0041] Specifically, the polyhedral spherical support 11 is a space truss structure, which as a whole is in the shape of a sphere, and the more faces it has, the closer it is to the shape of a sphere. The shape of the solar panel 12 is the same as one of all the faces of the polyhedral spherical support 11. When the polyhedral support 11 is a regular polyhedron, it has the lowest manufacturing complexity, and when the multiple faces of the polyhedral support 11 are different, multiple shapes of solar panels 12 need to be manufactured to adapt to one face of the polyhedral support 11 of different shapes.

[0042] In some embodiments, the polyhedral spherical support 11 is a regular polyhedron.

[0043] Specifically, the regular polyhedron is a special shape of the polyhedral spherical support 11. This structure has many advantages, such as each face being the same so that the same shape of solar panel 12 can be used, which is suitable for mass production. In addition, due to the symmetrical structure, the structural stability is also good.

[0044] As shown in FIG. 1, in some embodiments, the regular polyhedron is a regular dodecahedron, and each face is a regular pentagon. Figures 2-3

[0045] ​​Specifically, the regular polyhedral shape can be selected as a regular dodecahedron, which is similar to a sphere such as a football. Of course, in addition thereto, the regular polyhedral shape can also be a regular hexahedron, a regular heptahedron, a regular octahedron, a regular nonahedron, and the like. Each face of these regular polyhedrons is identical in shape and size, and can be a regular pentagon or other shape.

[0046] As shown in FIG. 1, in some embodiments, the polyhedral support 11 is a hollow frame structure. Figures 2-3

[0047] Specifically, the polyhedral support 11 is a frame structure, and the interior thereof is empty. This not only saves material, but also reduces the weight of the polyhedral support 11.

[0048] As shown in FIG. 2, in some embodiments, the frame structure is composed of a plurality of connecting rods connected end to end. Figures 2-3

[0049] Specifically, the length of the connecting rod depends on the shape of the corresponding face of the polyhedral support 11 surrounded thereby. When the polyhedral support 11 is a regular polyhedron, the connecting rods used thereby are identical in size. The connecting rods can be cylindrical rods or cuboid rods. The material of the connecting rods can be metal or plastic.

[0050] As shown in FIG. 3, in some embodiments, the spherical solar power generation device further includes a base 7 for supporting the spherical solar assembly 1. The base 7 is a hollow frame structure. Figures 2-3

[0051] Specifically, the base 7 is also assembled from a plurality of connecting rods. When the connecting rods are metal, they can be connected together by welding. The shape of the base 7 can be a circular truncated cone, a circular cylinder, a square, or a cuboid. However, the interior thereof is hollow, so as to save material and reduce the weight of the base 7.

[0052] As shown in FIG. 4, in some embodiments, the base 7 includes a socket 111 at the top, and the shape of the socket 111 is adapted to the shape of a face of the regular polyhedron. Figures 2-3

[0053] Specifically, the upper portion of the base 7 is provided with a socket 111, and the shape of the socket 111 is identical to that of a face of the regular polyhedron, but the size of the socket 111 can be slightly larger than that of the face of the regular polyhedron, so as to facilitate the clamping of the polyhedral support 11.

[0054] ​​​​The spherical solar power generation device of this application consists of a spherical solar module 1, a controller 3, a battery pack 2, a DC / AC inverter 4, a DC load 6, and an AC load 5. The spherical solar module 1 comprises a multi-faceted spherical support 11 and solar panels 12. The bottom of the multi-faceted spherical support 11 is connected and fixed to the ground via a base 7. The solar panels 12 are fitted snugly to the frame of the multi-faceted spherical support 1 and connected via snap-fit ​​joints, increasing the distribution area of ​​the solar panels 12 per unit ground area and improving power generation efficiency. Solar energy is converted into current for the load through the spherical solar module 1, controller 3, battery pack 2, and DC / AC inverter 4. This significantly improves the power generation efficiency per unit ground area and reduces dependence on ground area.

[0055] In this application, the sun is one of the essential conditions. The spherical solar panel 1 converts the solar energy generated by the sun into electrical energy, and then the controller 3 stores the electrical energy in the battery pack 2 for energy storage use, or transmits the electrical energy to the AC load 5 or DC load 6 through the DC / AC inverter 4 to enable the end equipment to operate normally.

[0056] In traditional spherical solar modules 1, solar panels are distributed in a planar manner on a flat solar panel support. The flat solar panel support is at a certain angle, usually 20° to 55°. Because the solar panels are arranged in a planar manner, the power generation efficiency per unit area is not high, resulting in a lot of wasted space. At the same time, due to the planar arrangement, dust easily accumulates on the surface of the solar panels, which is not conducive to maintenance.

[0057] like Figures 2-3 As shown, in the spherical solar module 1, the solar panels are installed along with the frame of the multifaceted spherical support 11. Since the multifaceted spherical support 11 is a three-dimensional spatial structure, the area of ​​the solar panels 12 that can be installed inevitably increases. This improves the power generation efficiency per unit area of ​​ground. Simultaneously, because the solar module is spherical, dust and foreign matter are less likely to accumulate on the surface of the panels, reducing the maintenance cost of the solar power generation device. Because the spherical solar module 1 has a hollow structure, it can greatly improve the heat dissipation efficiency of the equipment and reduce the failure rate.

[0058] The spherical solar power generation device aims to improve the power generation efficiency of solar panels 12 per unit ground area and reduce dependence on the ground. At the same time, the spherical solar power generation device also reduces the maintenance costs of the solar panels 12 and lowers the equipment failure rate.
