A sun tracking device comprises a heat collector (6), a photoelectric induction device (2) installed on the heat collector (6), and a tracking driving device (5) used for driving the heat collector (6) to track the sun. The sun tracking device further comprises an information device (3) used for providing a position and a clock, and a control device (4) used for controlling the tracking driving device (5). The control device (4) is in communication with a meteorological station (1), the photoelectric induction device (2) and the information device (3) and receives the weather information of the meteorological station (1), the light intensity information of the photoelectric induction device (2) and the time and clock information of the information device (3). The sun tracking device is convenient to install as installation adjustment is reduced, the requirement for precision in manufacturing and machining is lowered, and installation cost is reduced. For all slot type heat collecting fields adopting astronomy tracking, the practical spatial position of a rotating shaft can be regularly detected, the tracking turn angle can be regulated, and tracking with higher precision can be achieved.
Description
technical field [0001] The invention relates to a tracking device for a trough-type solar concentrator, in particular to a tracking control device for a trough-type solar concentrator, and belongs to the technical field of energy utilization. Background technique [0002] As a clean, non-polluting renewable energy source, solar energy is considered an important part of the world's energy strategy for its development and utilization. Solar thermal utilization is the most important way in solar energy utilization. The trough-type solar thermal utilization system mainly uses the trough-type parabolic concentrator to concentrate the sunlight emission on the heat-collecting tube, and uses the medium in the tube to export the heat energy for utilization. It has a relatively high efficiency. High, large scale, easy to standardize and so on. [0003] Solar thermal power generation is a method to replace conventional energy sources, and it is one of the focuses of scientists and gov...
