  • the former type are commonly referred to as “single axis trackers” and the latter “dual axis trackers”.
  • a single axis tracker can be rotated about a single axis, usually parallel to the axis of rotation of the earth and or parallel to a ground plane, in order to track the apparent motion of the sun through the day. Since the orientation of a single axis tracker remains stationary in relation to other axes, multiple single axis trackers may be arranged to share a common drive arrangement. Thus, complexity and cost can be reduced. Although a single axis tracker can provide more effective solar radiation
  • a dual axis tracker can be rotated about two axes such that, in addition to tracking the apparent motion of the sun through the day, the angle of declination of the article can be adjusted in order to compensate for the seasonal change in solar elevation.
  • Dual axis solar trackers can be of particular benefit when used at higher latitudes, where the change in solar elevation is pronounced.
  • dual axis tracker employs an altitude-azimuth structure.
  • This form of dual axis tracker can be rotated about an axis parallel to the ground plane ("altitude” adjustment) and an axis perpendicular to the ground plane (“azimuth” adjustment) such that it can be orientated to any location in the upward hemisphere. Since the orientation of the axis parallel to the ground plane is not fixed with respect to a fixed datum point, when
  • each altitude-azimuth tracker positioned on a ground plane will require separate drive means for rotation about each axis.
  • An alternative dual axis tracker design is one whereby an article can be rotated about a fixed first axis parallel to the ground plane and can be rotated about a second axis which is not parallel to the first axis.
  • One such example can be found in WO 02/070966 in which a dual axis
  • heliostat is provided. This "heliostat" can be rotated about the fixed first axis by a drive shaft lying parallel to the first axis and can be rotated about the second axis by a drive member connected to the rear of a reflector element of the "heliostat" by a lockable ball joint. The drive member is then caused to pivot by a linearly moveable motion translating shaft. Since the effective length of the drive member will change as it is caused to pivot, either the drive member must be telescopic or the motion
  • translating shaft must be displaced toward, or away from the reflector element. Further, since the second axis is not fixed in relation to a fixed datum point, the motion
  • translating shaft must also rotate with the "heliostat" as it rotates about the first axis. This results in a

Abstract

L'invention concerne une monture mobile (1) destinée à supporter un dispositif de réflexion, de réception ou de transmission de rayonnement, comportant une base (4) et une surface de montage (2) sur laquelle le dispositif de réflexion, de réception ou de transmission de rayonnement est en mesure d'être monté. La surface de montage (2) est sélectivement rotative autour d'un premier et d'un second axe (9, 20) par rapport à la base (4). La monture (1) comporte par ailleurs un premier dispositif d'entrée (7), un second dispositif d'entrée (15) et un ensemble d'appui raccordant la surface de montage (2) aux premier et second dispositifs d'entrée (7, 15). Le premier dispositif d'entrée (7) est rotatif autour du premier axe (9) qui est fixe par rapport à la base (4), le premier dispositif d'entrée (7) fonctionnant pour faire tourner la surface de montage (2) autour du premier axe (9). Le second dispositif d'entrée (15) est rotatif autour du second axe (20) qui est fixe par rapport à la base, le second dispositif d'entrée (15) fonctionnant pour faire tourner la surface de montage (2) autour du second axe (20). L'ensemble d'appui comporte un premier et un second élément (12, 13), arrangés pour être concentriques et rotatifs l'un par rapport à l'autre autour d'un troisième axe (14), et les trois axes (9, 20, 14) croisent un point commun (A) qui est fixe par rapport à la base (4).
