Description

Technical Field

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

[0002] Energy storage mainly refers to the storage of electrical energy. The combination of photovoltaic power generation and battery storage is called photovoltaic + energy storage. Photovoltaic energy storage power stations are mainly used in conjunction with photovoltaic grid-connected power generation applications. Therefore, the entire system is a power generation system that includes photovoltaic module arrays, photovoltaic controllers, battery packs, battery management systems, inverters, and corresponding energy storage power station joint control and dispatch systems.

[0003] Photovoltaic energy storage equipment is generally installed in open environments such as the Gobi Desert. However, although the Gobi Desert can provide good sunlight, it is also often affected by strong winds, sandstorms, and other natural environmental factors. Foreign objects mixed in with the sand can collide with the photovoltaic panels and cause damage. Moreover, long-term dust adhesion can corrode the modules, further reducing their output power and even affecting their lifespan. Once this happens, there is no way to remedy the situation, and the only option is to replace the modules. Otherwise, it will affect the power generation and may also pose a safety hazard to the power station. Summary of the Invention

[0004] Based on this, the purpose of this invention is to provide an integrated photovoltaic energy storage device to solve the technical problem that existing integrated photovoltaic energy storage devices are easily damaged by natural factors such as strong winds and sandstorms.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an integrated photovoltaic energy storage device, comprising a base, a turntable rotatably connected to the top of the base, a battery fixed to the top of the turntable, a shield mounted on the top of the battery via a fixing frame, two photovoltaic panels slidably connected to the bottom of the shield, the two photovoltaic panels being staggered and unfolded on both sides of the bottom of the shield, a support plate fixed to one end of the battery, and a shaft connected to the other end of the support plate, two elastic plates movably connected to the shaft, the two elastic plates opening towards the photovoltaic panels, a bracket fixed to the bottom of the photovoltaic panels, a connecting shaft fixed to one end of the bracket, the connecting shaft being slidably connected to the inner side of the elastic plates, and a wind vane fixed to the end of the battery away from the support plate.

[0006] By adopting the above technical solution, when strong winds, sandstorms, or other weather conditions occur, the airflow is diverted by the two elastic plates, and the resulting wind pressure causes the elastic plates to deform inward. This deformation of the elastic plates causes the two photovoltaic panels to retract to the bottom of the shielding plate, thus protecting the photovoltaic panels. When the sandstorm stops, the elastic plates return to their original position using their elasticity, allowing the photovoltaic panels to be pulled out again for operation.

[0007] The present invention is further configured such that brushes are provided at the junctions of the shielding plate and the two photovoltaic panels.

[0008] By adopting the above technical solution, the dust on the photovoltaic panel can be brushed off by a brush when it is in use.

[0009] The present invention is further configured such that a telescopic rod is hinged between the inner side of the photovoltaic panel and the support plate, and a spring is sleeved on the outer side of the telescopic rod.

[0010] By adopting the above technical solution, the elastic plate is assisted in resetting.

[0011] The present invention is further configured such that the elastic plate is made of steel and has an arc-shaped structure.

[0012] By adopting the above technical solution, the steel sheet has good elasticity, can deform when subjected to wind pressure, and can return to its original position after the wind pressure disappears. The arc-shaped structure facilitates air guidance.

[0013] The present invention is further provided with a coil spring at the rotatable connection between the base and the turntable.

[0014] By adopting the above technical solution, the turntable can be reset using a coil spring after rotation.

[0015] The present invention is further configured such that the frame of the shielding plate has a sandwich structure, thereby offsetting the two photovoltaic panels.

[0016] By adopting the above technical solution, the two photovoltaic panels can be reasonably stored at the bottom of the shielding plate.

[0017] The invention is further configured such that a groove is provided on the inner side of the elastic plate, and a slider is slidably connected inside the groove, and the connecting shaft is hinged to the slider.

[0018] By adopting the above technical solution, the elastic plate and the connecting shaft can be movably connected.

[0019] The present invention is further configured such that there are two slides distributed vertically, and both ends of the connecting shaft are connected to the two slides respectively by sliders.

[0020] By adopting the above technical solution, the movement of the photovoltaic panel becomes more stable.

[0021] The present invention is further configured such that the shielding plate and the frame of the photovoltaic panel are connected by a slide rail, and the slide rail is provided with a limiting structure.

[0022] By adopting the above technical solution, a sliding connection between the shielding plate and the photovoltaic panel is achieved, and the limiting structure prevents the photovoltaic panel from moving excessively.

[0023] In summary, the present invention has the following main beneficial effects:

[0024] This invention incorporates components such as a turntable, a wind vane, and elastic plates. In the event of strong winds or sandstorms, the wind vane rotates due to the wind, causing the elastic plates to face the wind. The two arc-shaped elastic plates form a "sharp angle" structure, diverting the strong winds. The resulting wind pressure causes the elastic plates to deform inwards, retracting the two photovoltaic panels to the bottom of a shielding plate. This shielding plate protects the photovoltaic panels from impacts by foreign objects and prevents dust accumulation and corrosion. Once the sandstorm subsides, the elastic plates return to their original position, allowing the photovoltaic panels to be pulled out again for operation. This integrated photovoltaic energy storage device provides self-protection against strong winds and sandstorms. Attached Figure Description

[0032] 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.

[0033] The embodiments of the present invention will now be described.

[0034] A photovoltaic energy storage integrated device, such as Figure 1-6 As shown: The system includes a base 1 fixed to the ground, a turntable 2 rotatably connected to the top of the base 1, a battery 3 fixed to the top of the turntable 2, a shield 5 mounted on the top of the battery 3 via a mounting bracket 4, and two photovoltaic panels 6 slidably connected to the bottom of the shield 5. The two photovoltaic panels 6 are staggered and unfold on both sides of the bottom of the shield 5. The specific structure connecting the shield 5 and the two photovoltaic panels 6 is as follows... Figure 6 As shown: The frame of the shield 5 has a sandwich structure, which separates the two photovoltaic panels 6. Some of the electrical energy generated by the photovoltaic panels 6 is stored in the battery 3.

[0035] When strong winds, sandstorms, or other natural environmental conditions occur, foreign objects may collide with the photovoltaic panel 6 and damage it. Moreover, long-term dust adhesion can corrode the module and reduce its lifespan. Therefore, in this embodiment, a support plate 7 is fixed to one end of the battery 3, and a shaft 8 is connected to the other end of the support plate 7. Two elastic plates 9 are movably connected to the shaft 8, and the two elastic plates 9 open towards the photovoltaic panel 6. The elastic plates 9 are made of steel and have an arc-shaped structure. A bracket 12 is fixed to the bottom of the photovoltaic panel 6, and a connecting shaft 13 is fixed to one end of the bracket 12. The connecting shaft 13 is slidably connected to the inner side of the elastic plate 9. Specifically, a groove 10 is provided on the inner side of the elastic plate 9, and a slider 11 is slidably connected inside the groove 10. The connecting shaft 13 is hinged to the slider 11. A wind vane 14 is fixed to the end of the battery 3 away from the support plate 7.

[0036] When strong winds or sandstorms occur, the wind vane 14 is blown by the wind, causing the turntable 2 to rotate, which in turn rotates the main structure, turning the elastic plate 9 to the windward side. The two arc-shaped elastic plates 9 form a "sharp angle" structure, diverting the strong wind. The resulting wind pressure causes the two elastic plates 9 to move inward around the shaft 8. The elastic plate 9 is made of steel and is elastic; it also deforms inward under wind pressure. When the elastic plate 9 moves inward and deforms, it forces the guide slider 11 to slide inside the groove 10. The slider 11 and... The connecting shafts 13 will also rotate accordingly, thereby driving the connecting shafts 13 and the bracket 12 to move through the deformation of the elastic plate 9, which in turn causes the two photovoltaic panels 6 to retract to the bottom of the shielding plate 5. The two photovoltaic panels 6 are staggered, and the shielding plate 5 protects the photovoltaic panels 6, preventing foreign objects from colliding with the photovoltaic panels 6, and also preventing dust from accumulating on the photovoltaic panels 6 and causing corrosion. When the sandstorm stops, the elastic plate 9 uses its own elasticity to reset, thereby pulling the photovoltaic panels 6 out to work again, so that the photovoltaic panels 6 can achieve self-protection when facing strong winds, sandstorms and other weather conditions.

[0037] There are two slides 10, which are distributed vertically. The upper and lower ends of the connecting shaft 13 are connected to the two slides 10 respectively through the slider 11. This allows the photovoltaic panel 6 to be fully supported and the photovoltaic panel 6 to be very stable when moving.

[0038] In this embodiment, a telescopic rod 16 is hinged between the inner side of the photovoltaic panel 6 and the support plate 7, and a spring 17 is sleeved on the outer side of the telescopic rod 16. When the elastic plate 9 moves and deforms inward, it will squeeze the spring 17. After the strong wind stops, the spring 17 will reset, which can assist the elastic plate 9 to reset.

[0039] In this embodiment, brushes 15 are also provided at the junction of the shielding plate 5 and the two photovoltaic panels 6, so that when the photovoltaic panel 6 moves left and right, the dust on the surface of the photovoltaic panel 6 can be brushed off by the brushes 15.

[0040] The frame of the shielding plate 5 and the photovoltaic panel 6 are connected by a slide rail, and the slide rail is equipped with a limit structure to prevent the photovoltaic panel 6 from moving excessively.

[0041] After the wind stops, the orientation of the photovoltaic panel 6 may change. It can be returned to its original position by manually rotating the turntable 2. In this embodiment, a coil spring is also provided at the rotation connection between the base 1 and the turntable 2. When the turntable 2 rotates, it will be wound. After the wind stops, the return of the coil spring can drive the main structure back to its original position.

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.
