Solar tracking arrangement for controlling parabolic trough solar collectors, and a thermal solar energy system

摘要

The solar tracking arrangement enables a plurality of parallel arranged PTCs to be directed towards the travelling sun. The solar tracking arrangement comprises a drive means, a transmission means, and a plurality of conversion means. The transmission means are connected with the drive means and to each of the plurality of conversion means. The transmission means is configured to convey an operating movement caused by the drive means to the plurality of conversion means, and each of the conversion means is configured to convert the conveyed operating movement into a pivoting movement of a respective one of the plurality of PTCs about a focus line, such that each of the pivoting movements directs the respective PTC towards the travelling sun. One or more of the conversion means are adjustably connected with the transmission means in a direction along the transmission means.
