What Are Heliostats?
Heliostat refers to an optical device that reflects light from the sun or other celestial bodies to a fixed direction, also known as a heliostat. The effect is similar to that of a fixed mirror, but a flat mirror is placed in the equatorial device and can be moved in the declination direction. [1]
Heliostat device is a kind of directional projection sunlight
The "star-sucking method" of the heliostat tower. On this large football stadium, the most curious thing is the 32 large mirrors placed on the ground. The staff of the power station told reporters that these large mirrors are called "heliostats" and each mirror Heliostat
Both have a total area of 20 square meters. With the permission of the staff, the reporter slowly took the elevator to the 25-meter platform of the high tower and looked down. The reflection of the 32 mirrors was a bit dazzling and also made this seemingly barren site. Instantly become as gorgeous as the stage. "Heliostat" is like 32 "sunflowers", tracking the sun every moment, absorbing the sunlight greedily. At the top of the 33-meter-high tower next to the heliostat, there is a large circular hole. The staff of the power station told reporters that this large hole is like the "star-absorptive method" in Jin Yong's "Swordsman". The sunlight reflected by the 32 mirrors is all absorbed, and it looks like it is hanging in the sky from a distance. With "The Second Sun". The sunlight passes to the heat collector on the iron tower, and the heat of the collected light is 800-1000 degrees. At such high temperatures, the air pushes the generator to rotate and performs photoelectric conversion. Several cameras are installed on the tower's platform to monitor the movement of the tower at all times. The reporter saw that all 32 heliostats are controlled by automation, and dense circuits are shuttled under each mirror. Experts told reporters that according to the position of the sun every day, the angle of the heliostats must be controlled by a computer so that all heliostats can reflect the sunlight to the receiver, achieving the effect of "star-absorption." It turns out that this is the core of the first solar power station in China. These heliostats are like sunflowers, facing the sun every second. The sunlight is reflected to the bull's eye, and the heat collecting device gathers less and more, heating the air and generating electricity.
