Description
Technical field
The utility model relates to a kind of heliostat rotating supporting device, relates in particular to a kind of one-armed formula heliostat rotating supporting device.
Background technology
Heliostat is the beam condensing unit in the Solar Energy Heat Utilization System, and it is to gather on certain target after the sunlight reflection; Heliostat comprises solar energy mirror, bracing or strutting arrangement and tracking control system; Solar energy mirror is installed on the bracing or strutting arrangement, and control bracing or strutting arrangement by tracking control system and make heliostat constantly follow the tracks of sunlight, and will gather on certain target after the sunlight reflection, the bracing or strutting arrangement of heliostat comprises pillar, rotating shaft and mirror holder at present, its structure is simpler, but fastness, reliability and tracking accuracy are relatively poor.
Summary of the invention
At above-mentioned shortcoming, the purpose of this utility model is to improve its structure, provides a kind of fastness, reliability and tracking accuracy high one-armed formula heliostat rotating supporting device.
Technology contents of the present utility model is that a kind of one-armed formula heliostat rotating supporting device is characterized in that it comprises one-armed pillar, vertical rotating seat, vertical rotating seat transmission case, horizontal rotating shaft transmission case, rolling lead screw, rocking arm, horizontal rotating shaft and mirror holder; Vertical rotating seat is installed in the upper end of one-armed pillar, and vertical rotating seat transmission case is installed in the outside of vertical rotating seat and drives vertical rotating seat rotation, is used to change the azimuth of solar energy mirror; The mirror holder of solar energy mirror is fixed on the horizontal rotating shaft, horizontal rotating shaft is installed on the vertical rotating seat by an axle sleeve, on horizontal rotating shaft, fix a rocking arm, the horizontal rotating shaft transmission case is hinged on the vertical rotating seat, the horizontal rotating shaft transmission case is connected with rocking arm by rolling lead screw, the pulling horizontal rotating shaft rotates, and is used to change the elevation angle of solar energy mirror.
For the tracking accuracy that improves one-armed formula heliostat rotating supporting device is separately installed with photoelectric encoder on vertical rotating seat and axle sleeve; Horizontal rotating shaft can both detect with photoelectric encoder with the angle that vertical rotating seat rotates, in order to closed-loop control.
The advantage that the utility model is compared with prior art had is:
1, fastness of the present utility model and reliability height.
2, transmission accuracy height of the present utility model and flexibility are good.
3, tracking accuracy height of the present utility model.
