Description

Technical Field

[0001] The utility model relates to the field of photovoltaic components, in particular to a solar photovoltaic component. Background Art

[0002] During the encapsulation process of solar photovoltaic modules, the cells are first welded together, and then EVA film is used for high-temperature lamination and curing. In order to improve the sealing and strength of the module, high-transmittance glass is used on the front and back panel is used on the back. Aluminum frames are added to the sides for protection. When the module is installed and used outdoors, it is fixed on the bracket, and the bracket generally has a certain inclination angle, generally greater than 5 degrees. Therefore, during the use of the module, the dust on the surface of the module will be washed away by rainwater, which has a certain self-cleaning effect. However, the frame will be 3-5mm higher than the front glass, and rainwater and dust will still accumulate on the edge below the module, which will reduce the light receiving area of ​​the photovoltaic module, thereby reducing the power generation. At the same time, rainwater may also penetrate into the photovoltaic module through the gap in the frame, causing leakage inside the module or even scrapping.

[0003] In the existing technology, for example, the Chinese authorization announcement number is CN 208353284 U, which is a "solar photovoltaic module", which includes a module body and a frame arranged outside the module body, and the bottom of the frame is provided with at least two grooves, and the two grooves are respectively arranged near the two ends of the bottom of the frame.

[0027] The drainage mechanism 8 includes a guide plate 81, which is fixedly connected to the bottom of the inner cavity of the fixing seat 2, and a drainage hole 82 is opened at the bottom of the inner cavity of the fixing seat 2; by setting the drainage mechanism 8, when the solar panel works in rainy weather, rainwater spilled on the top of the solar panel can fall into the inside of the fixing seat 2, and the guide plate 81 can discharge the rainwater to the outside of the fixing seat 2 through the drainage hole 82, thereby avoiding the problem of corrosion of the solar panel caused by rainwater staying in the fixing seat 2 for a long time, thereby improving the protection effect of the solar panel.

[0031] The working principle of a solar photovoltaic module provided by the utility model is as follows:

[0032] Step 1: First, when the solar panel is used for a long time and dust is deposited on the surface, the rotating motor 5 is started, so that the rotating motor 5 can drive the sliding frame 3 to move through the threaded rod 6, that is, drive the brush plate 4 to move. At this time, the brush plates 4 moving on both sides can clean the dust on the top of the solar panel, thereby achieving the cleaning effect of the top of the solar panel, so as to avoid the problem of reduced work efficiency when the surface of the solar panel is dirty, thereby improving the long-term work efficiency of the solar panel. When the solar panel needs to be installed and fixed, the solar panel is placed inside the fixing seat 2. At this time, the bolt 72 is rotated so that the bolt 72 can fix the solar panel on the top of the positioning plate 71, that is, fixed inside the fixing seat 2, thereby bringing convenience to the installation and fixation of the solar panel. When the solar panel works in rainy weather, the rainwater sprinkled on the top of the solar panel can fall into the inside of the fixing seat 2.

[0033] Step 2: When the thickness of the solar panels installed inside the fixing seat 2 is different, the spring 92 can squeeze the brush plate 4 through the limit column 91, so that the brush plate 4 can be squeezed on the top of the solar panel, thereby avoiding the problem that it is difficult to clean solar panels with different thicknesses when the brush plate 4 is fixed, thereby improving the practical effect of the photovoltaic module. When the angle of the solar panel needs to be adjusted, the electric push rod 102 is started, so that the electric push rod 102 can drive the fixing seat 2 to flip through telescope, that is, drive the solar panel to flip, thereby facilitating the angle adjustment of the solar panel. When the solar panel is used outdoors, the protective cover 11 can shield the rotating motor 5, so that it is difficult for rainwater to fall to the outside of the rotating motor 5 when it falls, causing damage to the rotating motor 5, thereby improving the protection effect of the rotating motor 5, that is, increasing the service life of the solar photovoltaic module.

[0034] Compared with the related art, the solar photovoltaic module provided by the utility model has the following beneficial effects:

[0035] By setting up the rotating motor 5, when dust is deposited on the surface of the solar panel after long-term use, the rotating motor 5 is started, so that the rotating motor 5 can drive the sliding frame 3 to move through the threaded rod 6, that is, drive the brush plate 4 to move. At this time, the brush plates 4 moving on both sides can clean the dust on the top of the solar panel, thereby achieving the cleaning effect of the top of the solar panel, avoiding the problem of reduced working efficiency when the surface of the solar panel is dirty, thereby improving the long-term working efficiency of the solar panel.
