Technical Field
The utility model relates to a solar energy beam condensing unit technical field specifically is a parabolic mirror spotlight solar device of non-tracking formula.
Background
The utilization of solar energy technology is more and more emphasized at present, the solar energy heat utilization is a technology which is relatively hot, the efficiency of directly utilizing the solar energy is generally low, and the efficiency is generally improved by a light-gathering and heat-collecting technology. The light-gathering and heat-collecting technology can be divided into a tracking type and a non-tracking type according to whether the reflector rotates along with the sun or not, the tracking type light-gathering and heat-collecting technology needs to track the position of the sun in real time, the cost is high, the light-gathering and heat-collecting technology is generally used for large-scale photo-thermal power stations and the like, and the non-tracking type light-gathering and heat-collecting technology is more suitable for small-scale factories and communities. For the non-tracking solar energy light-gathering reflector, the light-gathering efficiency of the common parabolic reflector is low, and although the light-gathering efficiency of the composite parabolic reflector is high, the shape is complex, the industrial processing is not facilitated, and the cost is higher. To the defect that above-mentioned technique exists, the utility model provides a parabolic mirror spotlight solar device of non-tracking formula.
