Description

technical field [0001] The invention relates to a mechanism for tracking the sun and its application, and belongs to the technical field of solar energy utilization. Background technique [0002] Using low cost and simple methods is very important for sun tracking and concentrating solar energy utilization. For this reason, many people at home and abroad have proposed many methods and mechanisms for tracking the sun. These technologies can be attributed to the following five categories: [0003] One is to use a set of control and transmission system to control a solar receiver, this method is the simplest, but the cost is very expensive; [0004] The second is to use a set of control and transmission system to control the condensing of multiple cylindrical condensers, which is a single-axis tracking condensing. The condensing area of ​​this method is a focal line area, which cannot generate high temperature and has a medium cost; [0005] The third is to use a set of contro...
