Disc type solar directional tracking device

The invention discloses a disc type solar directional tracking device that is applied to a unit for collecting the solar energy in a solar high-temperature generator set. The disc type solar directional tracking device comprises a hydraulic drive device with a control system, a plurality of groups of disc type solar units connected with the hydraulic drive device by flexible pipes. The disc type solar units contain pedestals, vertical rotating shafts arranged on the pedestals, hydraulic motors arranged at the middle parts of the vertical rotating shafts, support frames arranged at the upper ends of the vertical rotating shafts, horizontal rotating shafts arranged on the support frames, motors arranged at the outer sides of the support frames and are connected with the horizontal rotating shafts, cambered-surface-shaped disc type solar heliostats fixedly connected to the middle parts of the horizontal rotating shafts, and heat collectors matching the solar heliostats. The heat collectors are connected with the generator set by heat-transfer mediums. According to the invention, the azimuthal angles of the sun can be tracked all the time; the receiving angle can be adjusted automatically; and the solar energy can be utilized fully.
