Abstract

The present invention is one solar energy heat phase change tracking device. Under the masking board, there are the first heat collecting phase change device and the second heat collecting phase change device on two sides separately, and heat collecting phase change devices are cylindrical. Each of the heat collecting phase change devices has one end connected to one end of driving cylinder separately, and the driving cylinder is provided with piston and connected link rod mechanism. Inside each heat collecting phase change device, there is phase change liquid material. The solar light collector is connected to the solar energy heat phase change tracking device for tracking sun automatically to raise energy flow density. The present invention is simple and low in cost, needs no electric power, and may be used in sun height elevation tracking and sun azimuth tracking.

Description

technical field [0001] The invention relates to a solar energy utilization device, in particular to a solar tracking device. Background technique [0002] At present, there are many kinds of devices for concentrating solar energy, such as trough-type solar concentrators, disc-type solar concentrators, etc. Most of them design the solar concentrators as translational paraboloids or rotating paraboloids, so that the parallel irradiated sunlight After reflection, gather into points or lines and use them. Since the angle of the sunlight is changing, no matter whether it is a trough type, a disc type or other concentrators, there is a common problem: how to make the concentrator move accordingly. At present, the control scheme of the sun automatic tracking device using various photoelectric sensors and servo motor variable speed control is relatively mature, and the precision is also high, but there are disadvantages such as relatively expensive pr...
