More Information
Summary:The invention belongs to the field of solar tracking supports, and applies to solar photovoltaic inexact automatic tracking. The differential-pressure-type automatic solar tracking device comprises a pressure difference generation device, a transmission mechanical device and a nighttime resetting device, wherein the pressure difference generation device comprises a middle partition board, organic working medium metal sealing tubes embedded in paraboloid grooves in two sides of the partition board and a metal deformation actuator, a set of gas tubes are arranged on the periphery of a reflection mirror to serve as hour-angle tracking sensors. The invention aims to provide the differential-pressure-type automatic solar tracking device which can gather light through solar angle change to enable sealed organic media to expand and drive a differential pressure mechanical mechanism to rotate to track the sun.
