POSITIONING DEVICE FOR PARABOLIC TROUGH COLLECTORS AND PARABOLIC TROUGH COLLECTOR INCORPORATING SAID POSITIONING DEVICE

摘要

The invention relates to a positioning device for parabolic trough collectors. The invention also relates to the parabolic trough collector that incorporates said positioning device. The positioning device comprises a bearing structure (20) supporting parabolic trough mirrors (30), an actuator (10) comprising a drive wheel (11) adapted to be positioned coaxially to the rotation axis of the bearing structure (20) and solidly connected to the structure for the rotation thereof, an actuation means (12) for actuating the drive wheel (11) of the actuator (10), a casing (13) containing the drive wheel (11) and adapted to be joined to a post (40) that extends to the ground, and a bearing positioned coaxially to the axis of rotation of the actuator (10) and disposed between the drive wheel (11) and the casing (13) in order to transmit forces.
