Abstract

PROBLEM TO BE SOLVED: To provide a solar reflector which sets ground utilization efficiency with respect to the sun at 100%, which wards off wind pressure by a lightweight slit structure, and which can be constructed as a lightweight type.SOLUTION: In a circular and beam-like stand-alone solar reflector 2, a reflecting parabolic antenna is circumferentially split or split in a fan shape; two layers and an effective part overlap each other; a slit structure with a rib 6 is resistant to wind pressure; the risk of a wobble accident of a condensing point is eliminated by virtue of light weight; the condensing point is fixed on a ground side by a known trestle; and a rate of solar utilization on the ground reaches 100%.

Description

  The present invention relates to safe concentration of solar energy and heat collection.

  Conventionally, there are solar condensing and heat collecting which collect and collect heat with a parabolic antenna or a Fresnel lens.

  However, parabolic antennas cannot be used in large areas, and condensing point wandering accidents are dangerous. Fresnel lenses are prism-spectral and cannot be enlarged.

  Circumferentially-divided parabolic antennas can be increased in wind pressure and size, but focusing near the center is disadvantageous.

Some of these improvement measures are heliostat towers that focus on the ground with double reflection, but the solar operation is three-dimensional, the ground equipment is in a plane arrangement, the longitude utilization rate is 1/2, the latitude direction is 1/2, The total utilization rate is about 1/4 for solar ground irradiation, and the double-reflecting heliostat using many small objects is enlarged to counteract wind pressure, material temperature expansion, and load variation, and the structure is similar to an astronomical telescope. Become complicated.

The problem we are trying to solve is
1. When the parabolic antenna has a large area, the focal point becomes a long distance.
2. Existing light collection and long-distance light collection have a danger of a light-condensing point accident, and the solar utilization efficiency is about 1/4.
3. Concentration in the vicinity of the center is disadvantageous for the circumferentially divided parabolic antenna.

  The present invention takes advantage of parabolic antennas either radially, circumferentially divided, or a combination of the advantages of both.

  By using the safety division antenna of the present invention, it is possible to construct a lightweight structure that is 100% ground use efficiency with respect to the sun, from a small size to a large size, receives wind pressure with a lightweight slit structure.
