Flexible photovoltaic module

Abstract

The invention relates to the technical field of photovoltaic devices, and relates to a flexible photovoltaic module. The flexible photovoltaic module comprises a side cover, a reel, a flexible photovoltaic panel, a pull block and a crank, and the lower end of the side cover is a plane; rotating blocks are arranged at the two ends of the pull block; a rotating groove is formed in the upper end of each rotating block in a penetrating manner; a spiral drill is rotationally connected into each rotating groove; the lower ends of the spiral drills are lower than the lower ends of the rotating grooves, and a groove is formed in the side wall of each spiral drill; and the upper ends of the spiral drills are higher than the upper ends of the rotating grooves and are matched with the crank. The spiral drills matched with the crank are arranged, so that the pull block can be in relatively fixed connection with the ground after the spiral drills drill into the ground, and meanwhile, the lower end face of the side cover has relatively large friction force with the ground, so that the flexible photovoltaic panel can be stably spread on the uneven ground at the maximum area; and the module can not be lifted easily under the condition of large wind power, has high stability and can keep normal work.

Description

technical field [0001] The invention relates to the technical field of photovoltaic devices, in particular to a flexible photovoltaic module. Background technique [0002] With the rapid development of society, people are increasingly aware of the limitations of non-renewable energy sources such as petroleum, and people are constantly trying to develop and utilize solar energy to cope with the upcoming energy crisis; flexible photovoltaic panels, also known as thin-film solar cells, are the key to alleviating the energy crisis. New photovoltaic devices; thin-film solar cells can be manufactured using cheap ceramics, graphite, metal sheets and other materials as substrates. The thickness of the film that can generate voltage is only a few μm, and the current conversion efficiency can reach up to 13%. In addition to being flat, thin-film solar cells can also be made into non-planar structures because of their flexibility. It has a wide range of applications, and can be combine...

Problems solved by technology

In addition to being flat, thin-film solar cells can also be made into non-planar structures because of their flexibility. It has a wide range of applications, and can be combined with buildings or become a part of buildings. It has a wide range of applications; it can be used outdoors Generally, it is rolled up, which is convenient for saving space and carrying. It is laid flat on a flat ground with good light, and directly contacts the sun’s rays with the largest spreading area. However, the flexible photovoltaic panel has a slope on the ground and is not flat enough for use. It is difficult to be fixed, making it difficult for the flexible photovoltaic panel to keep the maximum tiled area in contact with sunlight, or even unable to spread; when the ambient wind is strong, the flexible photovoltaic panel is easily lifted by the wind, with poor stability and limited applicable environments.

[0003] For example, a Chinese patent with the application number CN201220378929.4 discloses a portable solar power supply, which includes a flexible solar battery pack, a main casing with a cavity structure inside, and The end cover, the rotating handle and the rotatable reel arranged inside the main housing, the two ends of the reel are respectively connected to the end cover and the rotating handle; the side wall of the main housing is carved with slots, and the flexible solar energy One end of the battery pack is fixedly connected to the reel through the slot; the technical solution uses a rotating handle to drive the reel to shrink the solar battery pack, which is free to shrink and easy to locate; The negative electrode has a strong bending ability and a compact product structure design; however, it is difficult for this technical solution to spread the solar battery pack stably on uneven ground, and it will be lifted up in the case of strong wind, which will affect the normal work, thus The limitations caused by the technical solution
