Embodiment Construction

[0026] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] Such as figure 1 , figure 2 , image 3 As mentioned above, the self-tracking solar power generation device in this embodiment has a double-layer glass 6 with a cavity and the inside is filled with low-pressure protective gas. The outer surface of the front side glass 1 is shaped on several vertical arc-shaped light-transmitting protrusions 2 arranged in sequence, and the arc-shaped light-transmitting protrusions 2 form a vertical strip-shaped convex lens that can gather light. The cavity of the double-layer glass 6 is provided with A bracket with an arc-shaped track 9 corresponding to the convex lens one-to-one, the bracket has a pair of support sheets 3 positioned at the upper and lower ends, the support sheet 3 is provided with an arc-shaped groove forming the arc-shaped track 9, and the mounting seat 4 There are inserts 10 inserte...

Abstract

The invention relates to a self-tracking solar power generating device which is provided with double layers of glass with a cavity. Multiple vertical arc light transmitting protrusions arranged in sequence are arranged on the front side glass. The vertical arc light transmitting protrusions form vertical strip-shaped convex lenses capable of condensing light. Supports, with arc rails, corresponding to the convex lenses in a one-to-one mode are arranged in the cavity. Mounting bases capable of sliding along the arc rails are mounted on the supports. The front surfaces of the mounting bases are fixedly provided with solar cells. The self-tracking solar power generating device is further provided with a driving mechanism for driving the mounting bases to slide in the arc rails. In effective solar energy collection time periods, the driving mechanism drives the mounting bases to enable incident sunlight to basically irradiate the solar cells in a covering mode after the incident sunlight is concentrated by the convex lenses. According to the self-tracking solar power generating device, the consumption of the solar cells can be reduced greatly, production cost is reduced, the utilization rate of solar energy is increased, the incident sunlight is concentrated when penetrating through the glass, blocking of the sunlight by bird dung is reduced, a dark area cannot be generated on the solar cells, and therefore a heat island effect is eliminated.

Description

technical field [0001] The invention relates to a self-tracking solar power generation device. Background technique [0002] With the improvement of people's awareness of environmental protection, the demand for clean energy is increasing. Among the new clean energy researched by people, solar energy, as a clean energy that is not subject to geographical restrictions, has become the main direction of new energy development in the future. Solar cells are the main devices that people use the sun's light energy to convert into electrical energy. [0003] At present, solar cells are all processed with silicon as the base material. Since silicon is easily oxidized in the air, the solar cells need to be packaged. Traditionally, two pieces of glass are used to bond the front and back of the solar cell for packaging. At present, the mainstream solar cell packaging uses fluorine-containing resin and other transparent resins instead of glass as the packaging material. Taking a 250W ...
