The invention relates to the field of solar energy application, and discloses a transmission device for a heliostat. The transmission device can be used for a solar tower-type generation system and a photovoltaic biaxial sun-tracking system. The transmission device for the heliostat comprises a shaft sleeve which is fixedly arranged on the top end of the vertical shaft of the heliostat horizontally, a rotating shaft which is matched with the shaft sleeve, a fixed plate which is connected with the end of the rotating shaft and the middle part of the back plate of the heliostat, and a transmission mechanism which is fixedly arranged on the shaft sleeve; the output end of the transmission mechanism is movably connected with the side part of the back plate of the heliostat; the transmission device for the heliostat is characterized in that the transmission mechanism comprises a combination of a gapless ball bearing lead screw with pre-tightening force and a nut; a shell body is arranged outside the nut; a gear is arranged in the shell body; outer teeth which are meshed with the gear are arranged on the nut; a driving motor which is in transmission connection with the gear is fixedly arranged outside the shell body; and the output end of the lead screw is movably connected onto the side part of the back plate of the heliostat.
Description
Technical field [0001] The invention relates to the field of solar energy applications, and in particular to a transmission device for a heliostat, which can be used in a solar tower power generation system and a photovoltaic biaxial sun tracking system. Background technique [0002] With the continuous expansion of solar energy application fields and the continuous improvement of solar energy application technology, the supporting technologies of related industries are also developing faster and faster, and the requirements for technology are also getting higher and higher. As an important device of the solar tower power generation system, the performance of the heliostat plays a vital role in improving the efficiency of the power generation system. Solar tower thermal power generation requires a large number of heliostats to concentrate sunlight on the heat exchanger installed on the top of the tower. Therefore, the heliostats need to follow the sun to make the reflected light ...
