Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic equipment, and in particular to a portable photovoltaic emergency power station. Background Art

[0002] Photovoltaic power generation, as a renewable energy power generation technology, has been widely used around the world. Traditional photovoltaic power stations are mostly in the form of fixed ground power stations or distributed power stations combined with buildings. The electricity generated by these power stations is mainly used locally or transmitted to other areas through long-distance power supply lines, thus forming a beneficial supplement to traditional power grid power supply; however, in remote areas where power supply is relatively scarce, outdoor work scenarios, and power outages caused by disasters, traditional photovoltaic power stations or grid power supply methods often cannot meet immediate and flexible power demand.

[0003] In the related technologies, although there have been solutions for mobile photovoltaic power stations, the more common form is the containerized photovoltaic energy storage power station. Although this type of power station has achieved mobility to a certain extent, due to its heavy weight and large size, it usually needs to rely on large-scale mechanical equipment for transportation and deployment. In complex environments such as remote areas or disaster sites, due to poor or blocked road conditions, the transportation and installation of such large mobile photovoltaic power stations becomes extremely difficult or even impossible, so there is room for improvement. Utility Model Content

[0004] In order to solve the problem that traditional power stations are bulky and difficult to transport, the present application provides a portable photovoltaic emergency power station.

[0005] The portable photovoltaic emergency power station provided in this application adopts the following technical solution:

[0006] A portable photovoltaic emergency power station comprises a plurality of photovoltaic panel modules, wherein the plurality of photovoltaic panel modules are arranged in sequence, any of the photovoltaic panel modules can be folded with adjacent photovoltaic panel modules, a Velcro for connection is provided between two photovoltaic panel modules in the same transverse direction, a hanging plate is provided between two photovoltaic panel modules in the same longitudinal direction, a plurality of eyelets are penetrated through each of the hanging plates, any of the photovoltaic panel modules comprises four groups of submodules, and any of the submodules can be folded with adjacent submodules.

[0007] Since traditional power stations are heavy and bulky, they usually need to rely on large mechanical equipment for transportation and deployment. In complex environments such as remote areas or disaster sites, due to poor or blocked road conditions, the transportation and installation of such large mobile photovoltaic power stations become extremely difficult or even impossible. By adopting the above technical solution, including a number of photovoltaic panel modules, adjacent photovoltaic template groups can be folded and arranged, and adjacent photovoltaic templates can be detachably installed. Each photovoltaic panel module consists of four groups of sub-modules, and the four groups of sub-modules can be folded. When the photovoltaic emergency station is used, the rotational molding box is opened, and the photovoltaic panel modules stored inside are taken out one by one. Since the photovoltaic panel module adopts a foldable design, the taken out photovoltaic panel module is unfolded according to its design structure. At the same time, since the foldable design is adopted between each module and between the sub-modules in the module, the unfolding process should be carried out smoothly, and the adjacent photovoltaic panel modules are aligned in the horizontal direction, and then the modules are pre-set between the modules. The modules are connected by Velcro in between, and in the longitudinal direction, adjacent photovoltaic panel modules are connected by a mounting plate. The eyelets on the mounting plate are passed through ropes or other connectors to firmly fix the modules together to complete the overall installation. The photovoltaic panel module, Velcro, eyelets and sub-modules are arranged in a foldable design to reduce the overall volume, greatly reduce the overall weight of the power station, and further improve its portability, so that the power station can be transported by personnel or airdropped to easily cope with the complex environment of remote areas or disaster sites. The Velcro and mounting plate design between the modules makes the installation and disassembly process of the power station fast and simple, and has a wide range of application scenarios. It can be laid flat on the ground, laid flat on the top of a tent, and hung on the side of a vehicle or a house, which greatly improves the flexibility of the power station deployment.

The insulating area has excellent insulation performance, which can effectively isolate the current between the submodule and the external environment, and prevent the occurrence of electrical accidents such as leakage and short circuit. Especially in humid, dusty or heavily polluted environments, the insulating area can prevent moisture and dust from entering the submodule, thereby ensuring the stable operation of the power station. At the same time, the insulating area also serves as a protective layer to enhance the weather resistance of the submodule, and can resist the erosion of natural factors such as ultraviolet rays, rain, wind and sand, thereby extending the service life of the submodule.

[0010] Optionally, a high temperature tape is further provided on the surface of the submodule, and the high temperature tape covers the insulating area of ​​the submodule.

[0014] Optionally, the processing spacings between the four submodules in the same photovoltaic module are 5 mm, 10 mm, and 15 mm respectively.

[0015] By adopting the above technical solution, the processing spacing between the four sub-modules is 5mm, 10mm, and 15mm respectively; by setting the sub-module processing spacing, taking into account the thickness of the photovoltaic panels and the fabric, the photovoltaic panels and the fabric will occupy a certain space when they are combined into a module. A reasonable spacing should ensure that after the module is assembled, the components will not squeeze each other or produce excessive gaps, thereby ensuring the safety and stability of the module.

[0016] Optionally, each of the submodules includes a black fiber reinforced film, a battery string, a transparent fiber reinforced film, a packaging film and a flexible front plate, and the black fiber reinforced film, the battery string, the transparent fiber reinforced film, the packaging film and the flexible front plate are arranged in sequence from bottom to top.

By selecting the number of battery strings and the flexible front panel material, 2-3 battery strings are used to ensure that the submodule has a certain redundancy and reliability while maintaining a high photoelectric conversion efficiency. At the same time, the flexible film is selected as the flexible front panel material, which makes the photovoltaic module have better flexibility and bendability. The thickness of the flexible film is controlled in the range of 15-50μm, which ensures the transparency and light transmittance of the front panel.
