Corner-protecting structure of frameless solar photovoltaic cell module

Abstract

The invention provides the corner-protecting structure of a frameless solar photovoltaic cell module, and belongs to the technical field of solar photovoltaic modules. The corner-protecting structure comprises a corner-protecting body. The corner-protecting body comprises an elastic pressing plate, a supporting plate and a side plate. The elastic pressing plate and the supporting plate are corresponding to each other up and down. A cavity, enclosed by the elastic pressing plate, the supporting plate and the side plate together, serves as the embedded cavity of the module body. The elastic pressing plate is composed of a first folded edge, a second folded edge and a third folded edge. The first folded edge is connected with the upper edge of the side plate. The second folded edge is connected with the first folded edge. The third folded edge is connected with the second folded edge. The corner parts of the elastic pressing plate are provided with elastic pressing plate isolation trenches arranged on the elastic pressing plate. By means of the elastic pressing plate isolation trenches, an angle alpha and an angle beta are formed at the corner parts of the elastic pressing plate. The corner-protecting structure of the frameless solar photovoltaic cell module is good in clamping cooperation effect, and long in service life. Meanwhile, the overall photovoltaic conversion effect of a solar photovoltaic cell panel can be ensured. The structure is excellent in corner-protecting effect, simple and high in machining efficiency.

Description

technical field [0001] The invention belongs to the technical field of solar photovoltaic components, and in particular relates to a corner protection structure of a frameless solar photovoltaic cell component. Background technique [0002] With the increasing awareness of human energy conservation and environmental protection, as well as the protection awareness of non-renewable natural energy such as oil, coal, natural gas and even sea ice, as an inexhaustible clean new energy source, solar energy is becoming more and more important. The more it is valued by all mankind, the application of solar photovoltaic power generation systems continues to expand. Solar photovoltaic cell modules are an important part of a complete set of solar photovoltaic systems, and their function is to directly convert solar energy into electrical energy by using photovoltaic special effects. [0003] There is no lack of technical information about solar photovoltaic cell components in the publi...

Problems solved by technology

However, there are the following shortcomings: First, according to paragraph 0018 of its manual, the corner protector is made of weather-resistant silicone elastomer, and die-casting is performed using a flat vulcanizer at 170°C (the length of the right-angle side is 35.3mm, and the two side surfaces The length is 5.4㎜), it can be seen that this kind of corner protector is relatively fragile due to the use of rubber, and the production process is troublesome; secondly, because the upper surface and the lower surface of the plane are curved surfaces, it is compatible with solar photovoltaic modules The contact is essentially tangential contact, and because the corner piece is made of rubber, it is difficult to ensure the effect of positioning on the solar photovoltaic module for a long time; third, because the overall shape of the corner is L-shaped, it is difficult to make the corner piece The intersection of the two right-angled sides and the corners of the solar photovoltaic cell module maintain an ideal matching effect, which will affect the overall cooperation and sealing effect of the entire corner protector and the solar photovoltaic cell module to a certain extent; Fourth, due to structural reasons, Therefore, the elastic force is relatively weak, so the clamping force or clamping force on the solar photovoltaic module cannot meet the expectations of the industry, and there may even be a risk of loosening
