Embodiment Construction

[0020] Such as Figures 1 to 5 shown (for clarity of view, Figures 1 to 4 The wires connected between the CIGS photovoltaic panel 1 and the power supply assembly 3 and the installation box 22 are not shown in the figure).

[0021] The photovoltaic mechanism includes an installation frame 2 , a sleeve 4 , a power supply assembly 3 and two CIGS photovoltaic panels 1 .

[0022] Two CIGS photovoltaic panels 1 are arranged side by side in sequence. A support 11 is provided on the back of each photovoltaic panel 1. The installation frame 2 is composed of a plurality of metal square tubes welded. The CIGS photovoltaic panel 1 support 11 and the installation frame 2 are fixed by bolts. A CIGS photovoltaic panel 1 bracket 11 is fixed on the installation frame 2 through C-shaped steel 21 and bolts. The C-shaped steel 21 is made of stainless steel (the C-shaped steel 21 can also be made of galvanized steel to achieve the same technical effect), and the CIGS photovoltaic panel 1 is in ...

Abstract

The invention provides a CIGS photovoltaic mechanism of a solar street lamp. The CIGS photovoltaic mechanism comprises a CIGS photovoltaic panel, a mounting frame, a sleeve and a power supply assembly, the CIGS photovoltaic panel is fixed above the mounting frame, and the sleeve is fixed on the lower side of the mounting frame; a heat preservation layer is laid on the inner wall of the power box of the power assembly, the battery is arranged in the power box, an air inlet and an air outlet are formed in the two sides of the power box, the two fans are installed at the air inlet and the air outlet respectively, the temperature sensor is installed in the power box, and a semiconductor chilling plate stretches into the inner cavity of the power box. The power supply assembly detects the temperature of a power supply box battery through a built-in temperature sensor, and when the temperature is reduced to be lower than the normal use temperature, the temperature of the battery is providedby controlling the semiconductor chilling plate to generate heat. When the temperature rises, redundant heat can be discharged through the reserved ventilation opening by means of the fans, or coolingis conducted through the semiconductor chilling plate, and the temperature of the battery is automatically adjusted by means of the power supply assembly and kept at a proper temperature.

Description

technical field [0001] The invention relates to a CIGS photovoltaic mechanism of a solar street lamp. Background technique [0002] CIGS photovoltaic panels are mainly composed of Cu (copper), In (indium), Ga (gallium), and Se (selenium), which have strong light absorption ability, good power generation stability, high conversion efficiency, and good weak light effect. Therefore, The daytime power generation time is long, the power generation capacity is high, the cost is low, and the cycle is short. Compared with the existing crystalline silicon photovoltaic panels, it has greatly improved in terms of cost, efficiency and power generation. However, the temperature of the battery of CIGS photovoltaic panel solar street lights will rise immediately in hot weather, which will lead to a decrease in the efficiency and life of the battery. And the current is unstable, which is easy to cause damage to the LED light source. Contents of the invention [0003] The technical prob...
