Abstract

The invention relates to a motorless full-automatic sun tracer. The motorless full-automatic sun tracer comprises heat-collecting tube shading controllers, heat-collecting tubes, conduits, drive cylinders and an adjustable solar energy utilizing equipment installation and control frame. According to the invention, the heat-collecting tubes are controlled by the heat-collecting tube shading controllers to absorb solar energy and heat enclosed gas in the heat-collecting tubes, expansion of the gas in the heat-collecting tubes is caused, and the expanding gas is led into the drive cylinders through the conduits to drive the cylinders to move, so that the adjustable solar energy utilizing equipment installation and control frame is driven to trace the incidence angle of sun light, and the highly effective utilization of the solar energy is realized. The motorless full-automatic sun tracer has the advantages that a motor and a control circuit are not needed, the structure is simple, the cost is low, the tracing effect is good, and the service lifetime is long.

Description

technical field [0001] The invention relates to the field of sun tracking equipment, in particular to a motor-free fully automatic sun tracking device. Background technique [0002] In recent years, with the advancement of material science and technology, the conversion efficiency of solar photovoltaic thermal utilization devices has been continuously improved, but because the efficiency of solar photovoltaic thermal utilization devices is greatly affected by the angle of incidence of the sun, and the impact of sunlight on a certain point on the earth in a day The angle of incidence of the sun is constantly changing, so it is necessary for the solar photoelectric thermal utilization device to be able to effectively track the angle of incidence of the sun. Most of the sun tracking equipment currently on the market use a single-chip microcomputer or PLC system to control the drive motor, and drive the solar photoelectric photothermal utilization device to track the angle of th...
