Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of heliostat sun tracking, and more specifically to a heliostat sun tracking device. Background Art
[0002] Heliostats are the main equipment of tower solar thermal power stations and the main investment part of the power station. They occupy the main site of the power station and their cost accounts for more than half of the total cost of the entire power station. The driver accounts for 24% to 33% of the cost of the heliostat. It can be seen that optimizing the driving mode of the heliostat can greatly reduce the cost of the tower solar thermal power station. At present, the heliostats of the tower solar thermal power generation system mostly adopt the azimuth + pitch angle sun tracking method, which rotates around the vertical axis and a horizontal axis respectively to achieve angle changes.
