Frame of solar photovoltaic module

Abstract

The invention discloses a frame of a solar photovoltaic module, which belongs to the technical field of solar photovoltaic modules. The frame of the solar photovoltaic module comprises a pair of longitudinal frame bodies, a pair of horizontal frame bodies and four angle connection devices, wherein the frame of the solar photovoltaic module has the characteristics that each of the longitudinal frame bodies is provided with a first through hole, a second through hole and a first photovoltaic cell panel installing embedded groove, wherein the first through hole and the second through hole penetrate to the other end from one end of the longitudinal frame body in the length direction; a longitudinal frame body enhancement strip is formed on the outer wall of a first wall body corresponding to the first through hole; each of the horizontal frame bodies is provided with a third through hole, a fourth through hole and a second photovoltaic cell panel installing embedded groove, wherein the third through hole and the fourth through hole penetrate to the other end from one end of the horizontal frame body in the length direction; a horizontal frame body enhancement strip is formed on the outer wall of a third wall body corresponding to the third through hole, and each angle connection device comprises a first right-angle connector, a second right-angle connector and a support reinforcing right-angle element. The frame of the solar photovoltaic module has the advantages that the strength of the longitudinal frame bodies and the horizontal frame bodies is improved, the effect of connection between the longitudinal frame bodies and the horizontal frame bodies is guaranteed, and the installation is fast and convenient; and by adopting nonmetallic materials, the disadvantage resulting from the use of aluminium profiles in the prior art can be eliminated.

Description

technical field [0001] The invention belongs to the technical field of solar photovoltaic components, and in particular relates to a frame of a solar photovoltaic component. Background technique [0002] As known in the industry, the overall structure of a solar photovoltaic module includes a frame, a solar photovoltaic glass installed on the frame, a cell (also called a silicon wafer or a silicon plate) under the solar photovoltaic glass, a hot melt adhesive layer, a junction box and an insulating backplane. The frame is customarily called the solar photovoltaic cell package frame. In the existing technology, aluminum alloy materials are almost uniformly used as frames. There is no doubt that the frames made of aluminum alloy materials have the advantages of strong oxidation resistance, high strength, good tensile performance, high fatigue resistance and long service life. And in the published Chinese patent literature, it can also be seen that the frames acted by aluminu...

Problems solved by technology

However, the strength of the horizontal frame and the vertical frame is still lacking. In particular, it is difficult for the corner connectors to be permanently and reliably fixed to the horizontal frame and the vertical frame, so there is also the risk of loosening or even cracking from the corners.
