Description

Technical Field

[0001] This invention relates to the field of photovoltaic and energy storage equipment, specifically to an integrated photovoltaic and energy storage power supply device. Background Technology

[0002] Photovoltaic power generation mainly consists of three parts: solar panels (modules), controllers, and inverters. The main components are made of electronic components. Solar cells are connected in series and then encapsulated for protection to form large-area solar cell modules. Combined with power controllers and other components, a photovoltaic power generation device is formed. Due to its particularly simple system structure and unique advantages—modular structure—it is suitable for power production of any scale, from large-scale central power plants to small-scale private residential power supply. With the maturity of photovoltaic power generation technology, integrated photovoltaic and energy storage power supply equipment has also been widely used.

[0003] In Northwest my country, where there is frequent sandstorms and other natural weather conditions, outdoor photovoltaic-storage integrated power supply equipment is affected by these weather conditions. Specifically, sand carried by the wind and sand can accumulate and adhere to the photovoltaic panels, causing corrosion and reducing their lifespan. In addition, sand and gravel carried by the wind and sand may collide with the photovoltaic panels, causing damage. Summary of the Invention

[0004] Therefore, the purpose of this invention is to provide an integrated photovoltaic and energy storage power supply device to solve the technical problem that existing integrated photovoltaic and energy storage power supply devices are susceptible to damage from windy and sandy weather.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an integrated photovoltaic and energy storage power supply device, comprising a sand collection bucket, a turntable fixed to the top of the sand collection bucket by a support frame, a top shell mounted on the top of the turntable, a groove provided on the top of the top shell, a fixing rod fixed to the top of the top shell above the groove, connecting plates provided on both sides of the fixing rod on the groove, a protective cover movably disposed inside the groove, second spur gears rotatably connected to the connecting plates on both sides of the protective cover, a battery module suspended at the bottom of the fixing rod, a photovoltaic panel mounted on the top of the fixing rod, a wind vane fixed to one side of the top shell, a rotating shaft rotatably connected to one side of the top of the top shell, a vertical pole fixed to the top of the rotating shaft, a sail fixed to one side of the vertical pole, and a first spur gear meshing with the second spur gear at one end of the rotating shaft.

[0006] By adopting the above technical solution, in windy and sandy weather, the wind vane will be used to rotate the sail to the windward side. The wind pressure will push the sail downward, and the transmission structure will be used to flip the protective cover upward, thereby covering the photovoltaic panel and protecting it.

[0007] The invention is further configured such that a rotating ring is rotatably connected to the bottom of the top shell, and a ring of paddles is provided on the outer side of the rotating ring. A first bevel gear and a second bevel gear that mesh with each other are installed inside the top shell. A first tooth path that meshes with the first bevel gear is provided on the outer side of the rotating shaft, and a second tooth path that meshes with the second bevel gear is provided on the inner side of the rotating ring.

[0008] By adopting the above technical solution, after the sandstorm stops, some sand will accumulate around the top shell. When the sail is reset, it will also drive the rotating ring and the deflector to rotate, thereby disturbing the sand accumulated here and causing the sand to flow into the sand collection bucket, thus preventing the sand from burying the top shell.

[0009] The present invention is further configured such that the protective cover is made of transparent rigid plastic material, and a counterweight ring is provided on the top of the protective cover.

[0010] By adopting the above technical solution, even when the protective cover is in place, sunlight will still shine through the cover onto the photovoltaic panels to generate electricity.

[0011] The present invention is further configured such that the edge of the photovoltaic panel matches the opening of the protective cover.

[0012] By adopting the above technical solution, the photovoltaic panel will not obstruct the rotation of the protective cover, and the protective cover can also provide sufficient protection for the photovoltaic panel.

[0013] The invention is further configured such that the top of the top shell is provided with a slot for placing the sail.

[0014] By adopting the above technical solution, it is easy for the sail to flip downwards.

[0015] The present invention is further configured such that the middle of the fixing rod has a cross-shaped structure.

[0016] By adopting the above technical solution, the fixing effect of battery modules and photovoltaic panels is more stable.

[0017] The present invention is further configured such that there is a gap between the rotating ring and the sand collection bucket.

[0018] By adopting the above technical solution, sand can be allowed to enter the sand collection bucket through the gap.

[0019] The present invention is further configured such that a coil spring is provided at the rotatable connection between the rotating shaft and the top shell.

[0020] By adopting the above technical solution, the rotating shaft can be reset using a coil spring.

[0021] The present invention is further configured such that the wind-receiving side of the sail has an inwardly concave arc-shaped structure.

[0022] By adopting the above technical solution, the sail can receive stable wind pressure.

[0023] The present invention is further configured such that the diameter of the first spur gear is greater than the diameter of the second spur gear.

[0024] By adopting the above technical solution, a small-angle rotation of the rotating shaft can drive a large-angle rotation of the protective cover.

[0025] In summary, the present invention has the following main beneficial effects:

[0026] This invention provides a protective cover for photovoltaic panels. During windy and sandy weather, a wind vane rotates the sail to the windward side, and the wind pressure pushes the sail downward. A transmission structure then flips the protective cover upward, thus covering the photovoltaic panels and protecting them. After the sandstorm stops, some sand accumulates around the top shell. When the sail returns to its original position, the rotating ring and lever rotate simultaneously, disturbing the accumulated sand and directing it into the sand collection bucket, preventing the top shell from being buried by sand.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0039] The embodiments of the present invention will now be described.

[0040] Example 1

[0041] A photovoltaic-storage integrated power supply device, such as Figure 1-10 As shown: The system includes a sand collection bucket 1, which is buried underground. A turntable 3 is fixed to the top of the sand collection bucket 1 via a support frame 2. A top shell 4 is mounted on top of the turntable 3, located above ground level and capable of rotating via the turntable 3. A groove 5 is provided on the top of the top shell 4. A fixing rod 6 is fixed to the top of the top shell 4 above the groove 5. Connecting plates 7 are provided on both sides of the fixing rod 6 on the groove 5. A protective cover 8 is movably installed inside the groove 5. Second spur gears 9 are rotatably connected to the connecting plates 7 on both sides of the protective cover 8. The middle of the fixing rod 6 has a cross-shaped structure. The bottom of the fixing rod 6 utilizes… The battery module 11 is suspended in a cross shape. The bottom of the battery module 11 is suspended and does not contact the protective cover 8. A photovoltaic panel 12 is installed on the top of the fixing rod 6. The electrical energy generated by the photovoltaic panel 12 is stored in the battery module 11. The electrical energy in the battery module 11 is used to power external equipment. A wind vane 13 is fixed on one side of the top shell 4. A rotating shaft 14 is rotatably connected to one side of the top of the top shell 4. A pole 15 is fixed on the top of the rotating shaft 14. A sail 16 is fixed on one side of the pole 15. A slot for the sail 16 is provided on the top of the top shell 4. One end of the rotating shaft 14 is connected to a first spur gear 17 that meshes with the second spur gear 9.

[0042] When encountering windy and sandy weather, the wind vane 13 is blown by the wind, causing the top shell 4 to rotate, which in turn rotates the sail 16 to the windward side. The windward side of the sail 16 has an inwardly concave arc structure, so the sail 16 will be subjected to strong wind pressure. The wind pressure pushes the sail 16 down, which in turn drives the rotating shaft 14 to rotate. The rotating shaft 14 drives the first spur gear 17 to rotate, which in turn drives the second spur gear 9 to rotate. In turn, the second spur gear 9 drives the protective cover 8 to flip. The top of the protective cover 8 is equipped with a counterweight ring 10. When the protective cover 8 flips to a certain angle, the weight of the counterweight ring 10 will assist in flipping down, and the protective cover 8 will flip up to cover the photovoltaic panel 12. Figure 10 As shown, this can protect the photovoltaic panel 12, preventing sand and gravel carried by the wind from colliding with the photovoltaic panel 12, and also preventing large-scale accumulation of dust on the photovoltaic panel 12. The protective cover 8 is made of transparent hard plastic. When the protective cover 8 is on, sunlight can still shine through the protective cover 8 onto the photovoltaic panel 12 to generate electricity. Although the irradiation efficiency is reduced, it is acceptable to sacrifice a little irradiation efficiency in this kind of weather, and then focus on protecting the photovoltaic panel 12. The edge of the photovoltaic panel 12 matches the opening of the protective cover 8, so that the protective cover 8 can completely cover the photovoltaic panel 12, with good protection effect, and the photovoltaic panel 12 will not block the rotation of the protective cover 8.

[0043] It should be noted that the diameter of the first spur gear 17 is larger than the diameter of the second spur gear 9, so that the protective cover 8 can be rotated at a large angle by the small-angle rotation of the sail 16.

[0044] A coil spring is provided at the rotating connection between the rotating shaft 14 and the top shell 4. When the sail 16 flips downward, the coil spring will be wound. When the wind and sand stop, the coil spring will reset, driving the rotating shaft 14 and the sail 16 to reset, thereby driving the protective cover 8 to flip downward and reset, so that the photovoltaic panel 12 can be exposed again for normal use.

[0045] After the sandstorm stops, some sand accumulates around the top shell 4 due to the shielding provided by the top shell 4 and the protective cover 8. Therefore, in this embodiment, a rotating ring 18 is rotatably connected to the bottom of the top shell 4, and a ring of paddles 19 is provided on the outer side of the rotating ring 18. A first bevel gear 21 and a second bevel gear 22 mesh with each other are installed inside the top shell 4. A first toothed path 20 meshes with the first bevel gear 21 on the outer side of the rotating shaft 14, and a second toothed path 23 meshes with the second bevel gear 22 on the inner side of the rotating ring 18. Thus, when the rotating shaft 14 is reset and reversed, the first toothed path 20 meshes with the second bevel gear 22. The first bevel gear 21 is driven to rotate by the second bevel gear 22, which in turn drives the second bevel gear 22 to rotate. The second bevel gear 22 drives the rotating ring 18 to rotate through the second gear 23, which in turn drives the paddle 19 to rotate. The rotation of the paddle 19 agitates the sand accumulated on the outside of the top shell 4, allowing the sand to enter the sand collection bucket 1 through the gap between the rotating ring 18 and the sand collection bucket 1. The sand in the sand collection bucket 1 can be cleaned periodically (for example, the bottom of each sand collection bucket 1 can be connected through a pipe, and then the sand in the sand collection bucket 1 can be pumped out through a sand pump at one end of the pipe).

[0046] Example 2

[0047] Unlike Embodiment 1, in this embodiment, an additional gear meshes between the first spur gear 17 and the second spur gear 9, so that the rotation directions of the first spur gear 17 and the second spur gear 9 are the same. When the sail 16 flips down, the protective cover 8 will flip up from the windward side. In this way, even if the wind and sand are not particularly strong, the protective cover 8 can still flip up at a certain angle on the windward side, which can also play a certain role in blocking the wind.

[0048] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the invention and are not intended to limit it. The specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and spirit of the invention, but such modifications, substitutions, and variations are protected by patent law as long as they are within the scope of the claims of the present invention.
