Apparatus for receiving and transporting solar energy

Abstract

A solar energy receiving and transmitting device comprises a light energy receiver and a light pipe (3), wherein the receiver comprises a plurality of bent light guide plates (1) coated with reflective films at surface, the light guide plates have consistent size, height and distance, two sides of the light guide plates are provided with a shell (2) whose inner surface is coated with a reflective film, the section of the end curved surface of the light guide plates have an angle with the center line of the light pipe of +-10 degrees. Therefore, light entered into the light pipe will not be reflected from other light guide channels. The receivers can be combined into a condenser, to collect and transmit the light energy of large area and low density into high-density light energy via low cost, thus is simpler and more practical than the prior art. The invention realizes maximum benefit under low cost, which is a best technique for developing and utilizing solar energy.

Description

technical field [0001] The invention belongs to the field of collecting and utilizing solar energy, in particular to a device for receiving and transmitting solar energy. Background technique [0002] At present, the world's energy is becoming increasingly tense with the gradual depletion of crude oil on the earth. Solar energy has attracted more and more attention as the main alternative energy source. However, the current solar energy utilization technology is still very immature, and the efficiency of solar cells is low. Large-scale use, and the other is the solar thermal power generation method. Due to the low energy density of the sun, the power generation device directly converts light energy into heat energy on site, which is expensive and difficult to promote. Therefore, efficient and low-cost transmission of solar energy with low energy density is required. Concentrate together to form high-density energy, which is then converted into electrical energy, heat energy,...

[0002] At present, the world's energy is becoming increasingly tense with the gradual depletion of crude oil on the earth. Solar energy has attracted more and more attention as the main alternative energy source. However, the current solar energy utilization technology is still very immature, and the efficiency of solar cells is low. Large-scale use, and the other is the solar thermal power generation method. Due to the low energy density of the sun, the power generation device directly converts light energy into heat energy on site, which is expensive and difficult to promote. Therefore, efficient and low-cost transmission of solar energy with low energy density is required. Concentrate together to form high-density energy, which is then converted into electrical energy, heat energy, or directly lighting the building

The patent No. 02234233.8 "solar energy long-distance receiving and transmitting device" published by the Chinese patent uses optical fiber as its light-conducting device. Because the diameter of the optical fiber is small, its focus cannot be well aligned with the center of the optical fiber. Although its condenser The head is coated with an anti-reflection film, and part of the reflected light is reflected into the atmosphere through the condenser lens. The patent No. 96115907.3 "solar power generation method" published by the Chinese patent is used as a device for collecting light sources, because the concave lens is used as a device for scattering light. , it is not feasible in principle, and the lens does not have an anti-reflection coating, so there will be a shortcoming of reflected light in the light pipe reflecting back and scattering into the atmosphere through the lens
