Tower-type solar energy heliostat bevel gear passive automatic sun-chasing support

The invention relates to the field of tower-type spotlight solar heat collection technology, spotlight solar energy photo-thermal power generation technology, and spotlight photovoltaic technology, in particular to a tower-type solar energy heliostat bevel gear passive automatic sun-chasing support. A gear base is arranged on the upper portion of the support, heliostats are arranged on both sides of the gear base. A reflection bevel gear, a transitional bevel gear, an incidence bevel gear, a reflection shaft and an incidence shaft are arranged on the upper portion of the gear base. The reflection bevel gear and the incidence bevel gear are co-axial and the reflection bevel gear, the incidence bevel gear and the transitional bevel gear are meshed. Axial directions of two bevel gears are perpendicular to an axial direction of the transitional bevel gear, the reflection bevel gear and the reflection shaft are mutually fixed, and the incidence bevel gear and the incidence shaft are mutually fixed. The silicon or spotlight solar panel is arranged on the incidence shaft, the photoelectric detector is arranged at the tail end of the incidence shaft, one end of the reflection shaft is connected with the main rotation reducer, and the other end of the reflection shaft is connected with a collimation calibration instrument. And a pitching driving structure one or a pitching driving structure two is arranged on the lower portion of the gear base.
