Description
technical field [0001] The invention relates to a hydraulic drive device for a trough solar concentrating heat collector, in particular to a hydraulic drive device for a trough solar concentrating heat collector with two hydraulic cylinders and one-dimensional tracking of the sun. 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 o...
