PURPOSE:To enable to make driving energy for slewing a heat collector unnecessary by a method wherein a bimetal is attached to the vicinity of the collector to slew the heat collector by utilizing the thermal deformation of the bimetal. CONSTITUTION:When solar radiation beam deviates from the collector 7 gradually in accordance with the movement of the sun and becomes to project the bimetal 10, the bimetal 10 is bent and displaced due to the thermal deformation thereof and pushes a bellows 13. According to this action, pressure transmitting medium 15 in the bellows 13 is pressurized, is induced into a cylinder 17, displaces a ram 18 and rotates a pinion 21, thus, an internal gear 23 is turned by the rotation of a gear train 22 and a transversing section 3 is transversed to sense the heat collector 7 toward the direction of the sun. As a result, the solar radiation beam deviates from the bimetal 10 and becomes to project the collector 7 again thereby enabling to make the driving energy for the traversing unnecessary. |
