PHOTOVOLTAIC PLANT SUN TRACKING SYSTEM Russian patent published in 2013 - IPC F24J2/54 F16M11/12 

FIELD: power engineering.

SUBSTANCE: photovoltaic plant Sun tracking system comprises a subsystem of azimuthal rotation (1) and a subsystem of zenithal rotation (2). The first drive via the first reducer rotates a spatial frame (10), where solar modules are installed, in azimuthal direction with the transmission ratio I_az and simultaneously rotates the third reducer with the transmission ratio I_az. On the driven gear of the third reducer there are two cams fixed, which interact with limit switches of the first drive. The second drive via the first reducer rotates the spatial frame (10) in zenithal direction with the transmission ratio I_zen and simultaneously rotates the fourth reducer with the transmission ratio I_zen. On the driven gear of the fourth reducer there are two cams fixed, which interact with limit switches of the second drive. Transmission ratios I_az, I_zen, I_az and I_zen meet certain ratios. The Sun tracking system does not require seasonal reconfiguration of limiters of limit angles of photovoltaic plant rotation, regardless of its geographic location on the planet.

EFFECT: system improvement.
