Dynamic sun-shading device integrated with PV (Photovoltaic) panels

Abstract

The invention discloses a dynamic sun-shading device integrated with PV (Photovoltaic) panels. The dynamic sun-shading device comprises a frame and a plurality of sun-shading boards which are distributed on the frame at equal intervals; the sun-shading boards are rotatably connected with the frame; each of the sun-shading boards comprises a front blade and a rear blade; when the sun-shading boards are in a completely closed state, the edges of the front blades and the rear blades of any two adjacent sun-shading boards are overlapped; the front blades and the rear blades are all cambered surfaces and different because the bending directions of the cambered surfaces of the front blades and the rear blades are opposite; a PV panel is additionally arranged on the upper surface of each of the front blades; the PV panels are driven by direct sunlight and all-sky diffused light to generate electric energy. The sun-shading device has a simple and convenient technical means, has the advantages of dynamic sun shading, lighting and power generation efficacy and the like and is especially suitable for lighting of roofs and atrium tops of large space buildings such as a terminal building, a transportation hub, an exhibition building and the like.

Description

technical field [0001] The invention relates to a sunshade device, in particular to a dynamic sunshade device integrating photovoltaic panels. Background technique [0002] Architectural sunlight is an important factor to be considered in architectural design, planning and design. Architectural shading is an effective means of shielding direct sunlight. It plays a positive role in maintaining uniform and stable indoor illumination and preventing overheating, such as airports, exhibition halls and other large spaces. Buildings generally adopt top lighting, which requires sufficient diffused light from the sky while effectively shading the sun. [0003] The lighting device on the top of the traditional building cannot realize dynamic adjustment, and the structure usually has the following disadvantages: [0004] (1) Zigzag skylight [0005] Zigzag skylight is a kind of roof lighting method widely used. Because opening the window facing north allows diffuse light from the sky...

AI Technical Summary

Problems solved by technology

[0003] The lighting device on the top of the traditional building cannot realize dynamic adjustment, and the structure usually has the following disadvantages:

But the disadvantage is that the lighting efficiency is low, and the maximum utilization of solar energy cannot be achieved to a certain extent.

Thin-film solar cells are semi-transparent materials with low light transmittance. As a uniform light-transmitting medium with low light transmittance, there are deficiencies in being directly used as building lighting materials.
