Offset type solar orienting line light-condensing desert surface hardening system

Abstract

The invention provides an offset type solar orienting line light-condensing desert surface hardening system and hardening method. The hardening system comprises a light condenser, a horizontal warp directional reflection mirror, a horizontal weft directional reflection mirror, a parabolic cylinder reflection mirror, a light-shielding reflection mirror, a computer, a solar position sensor, a solar radiation strength sensor, a horizontal sand plane and the like. The light condenser is a parallel light condenser; accurate azimuth angle and high-angle tracking on the sun are carried out; and output parallel light-condensing light passes through the horizontal warp directional reflection mirror, the horizontal weft directional reflection mirror and the parabolic cylinder reflection mirror to form the light-condensing light which is located on the surface of the horizontal sand plane and has the same radiation strength at each point. When the system is used for smelting and hardening the surface of a desert, movement energy and energy for smelting a sand surface are from solar energy and a fossil energy is not consumed; the utilization time of the solar energy is longer and the light-condensing position is relatively fixed; and the efficiency of smelting and hardening is high by adopting line focusing and utilizing the computer to control, and the quality is good; and unmanned automatic operation can be realized and the sand fixing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of solar energy utilization, in particular to a system for hardening desert surfaces by utilizing solar concentrated energy. Background technique [0002] Solar energy is a clean and non-polluting renewable energy source that is inexhaustible and inexhaustible. Fully exploiting solar energy can not only save the increasingly depleted fossil energy, alleviate the increasingly serious shortage of resources, but also reduce carbon pollution. , Respond to climate change and protect the ecological environment on which human beings depend. [0003] On the earth where we live, there are large areas of deserts. Because of the harsh natural environment, it is difficult for human beings to live and survive in these areas. Under the action of the wind, the fluidity of the desert can cause damage to the production and living facilities in the surrounding area, and eventually lead to unusability, and the human living sp...
