Description

A dynamic sunshade device integrating photovoltaic panels

technical field

The utility model relates to a sunshade device, in particular to a dynamic sunshade device integrating photovoltaic panels.

Background technique

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.

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

(1) Zigzag skylight

Zigzag skylight is a kind of roof lighting method widely used. Because opening the window facing north allows diffuse light from the sky to enter the room and blocks direct sunlight from the south, it can create a relatively uniform and stable natural light environment indoors. But the disadvantage is that the lighting efficiency is low, and the maximum utilization of solar energy cannot be achieved to a certain extent.

(2) Daylighting ceiling

Transparent/translucent lighting ceilings have high lighting efficiency, but the indoor natural light environment changes rapidly, there are obvious shadows, and there is a high possibility of glare problems. Using materials with low light transmittance can solve the above problems to a certain extent problem, but at the expense of reducing lighting efficiency.

(3) Thin film solar cells

Thin-film solar cells achieve the purpose of controlling their own transmittance by controlling their micropores, and it is precisely because of the existence of these micropores that the photoelectric conversion efficiency of this solar cell is low. 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.

Contents of the invention

The purpose of the utility model is to overcome the shortcomings and deficiencies of the above-mentioned prior art, and provide a dynamic sunshade device integrating photovoltaic panels. The device can generate electric energy while meeting the lighting and shading requirements on the top of the building.

A dynamic sunshade device integrating photovoltaic panels, comprising a frame 2 and several sunshade panels 3 distributed on the frame 2 in an equidistant array;

The sun visor 3 includes a front leaf and a rear leaf; when the sun visor 3 is in a fully closed state, the edges of the front and rear leaves of any two adjacent sun visors 3 overlap.

Both the anterior leaf and the posterior leaf are arc-shaped, and the difference is that the curved directions of the anterior leaf and the posterior leaf are opposite to each other.

A PV panel 4 is added on the upper surface of the front leaf; it is driven by direct sunlight and diffused light throughout the sky to generate electric energy.

The sun visor 3 is generally S-shaped or corrugated.

The rotation connection between the sun visor 3 and the frame 2 is through a connection structure; the connection structure includes an upper support rod 5 and a lower support rod 6; the upper support rod 5 is fixed below the rear leaf of the sun visor 3, and the lower support rod 5 The support rod 6 is fixed on the frame 2; the junction of the upper support rod 5 and the lower support rod 6 is provided with a shaft hole, and the rotating shaft 1 is placed in the shaft hole, and there is an interference fit between the rotating shaft 1 and the shaft hole; The sun visor 3 can rotate positively and negatively around the rotating shaft 1; the rotation angle of the sun visor 3 around the rotating shaft 1 is controlled, and the opening, closing and opening angle of the sun visor 3 are controlled to realize dynamic sun shading.

The sun visor 3 of the utility model is rotationally connected with the frame 2; by controlling the rotation angle of the sun visor 3 around the rotating shaft 1, the opening, closing and opening angle of the sun visor 3 are controlled to realize dynamic sun shading, so as to deal with indoor conditions according to different weather conditions. lighting needs.

The front leaf and the rear leaf of the sun visor 3 of the utility model are arc surfaces, and the difference is that the curved directions of the front leaf and the rear leaf are opposite to each other. The gaps between the sun visors 3 allow the diffused light from the sky and the scattered light formed by the reflection of part of the direct sunlight on the surface of the sun visor 3 to enter the room. Since the diffused light from the sky changes relatively little with time and the directionality is not strong, so It ensures a stable indoor natural light environment and avoids too strong brightness contrast and glare. The shortcomings and deficiencies of the current technology are overcome.
