Support device is trailed to single scale type biax

The utility model discloses a support device is trailed to single scale type biax, the device includes: flat axle photovoltaic support, a plurality of photovoltaic module of group, flat axle photovoltaic support includes the perpendicular bracing piece that sets up of a plurality of groups and level setting and the horizontal rotation axles be connected with a plurality of groups bracing pieces, a plurality of photovoltaic module of group fix at horizontal rotation epaxially through the every single move rotation axis respectively, the horizontal rotation axle is connected with the every single move gangbar that the level set up through electronic pivoted link mechanism, the every single move gangbar is passed through a plurality of every single move swinging arms and is connected with every every single move rotation axis respectively. The utility model discloses can follow the tracks of because the sun angle that earth rotation / revolution brought changes, realize that photovoltaic module's biax is followed the tracks of for guarantee that the photovoltaic cell board is perpendicular with the Sun's rays, increase photovoltaic cell board conversion efficiency.
