PURPOSE:To obtain the horizontal tracking type collector, which tracks the sun, by a method wherein a trestle and a heat collecting tube 12, attached to the trestle and integrated with a reflecting mirror, are pivoted when a driving unit is driven. CONSTITUTION:Supporting pillars 17 support the whole of the collector 11 and the trestle 15, to which the reflecting mirror 14 and the heat collecting tube 12 are attached through hinges 16, is fixed onto the pillars 17. An arm 19 is fixed to the trestle 15 and is moved by a driving mechanism (a hydraulic actuator 18) to effect the tracking of the reflecting mirror 14. Control command is outputted from a control unit in accordance with the movement of the sun to operate the hydraulic actuator 18 and pivot the trestle 15. According to this method, the reflecting mirror 14 faces to the direction of the sun at all times and collects the rays of light incident thereupon into the heat collecting tube 12 whereby heat collecting efficiency may be improved, structure may be simplified, assemblage may be facilitated and the cost may be reduced.
