Described the first traction piece or the second traction piece are hauling rope or traction curtain.
If the length direction in greenhouse is East and West direction, reflect focalization face one side has draw bar, for example, only have the first draw bar, and north side, without draw bar, only has southern side to have draw bar.
If the length direction in greenhouse is north-south, all there is draw bar reflect focalization face both sides, for example, have the first draw bar and the second draw bar.
When fine, can calculate the position angle of the sun on high according to astronomical rule, and according to the position of the position angle of the sun and solar receiver, can calculate reflect focalization face by sunlight focus reflection to the required angle of solar receiver.But due to the error that manufacture, installation and long-time running cause, reflect focalization face likely can not be focused on sunlight on solar receiver exactly.Therefore, need to use light radiation intensity sensor measurement to go out the position that reflect focalization face arrives sunlight focus reflection, and data accommodation reflex focusing surface accordingly, by sunlight focus reflection to solar receiver.
