PURPOSE:To secure a high heat collecting efficiency throughout the year by a method wherein a solar heat collector and the frame for fixing the solar heat collector are connected to each other with two pairs of support rods of different lengths in such a manner that the support rods are held rotatable with respect to the solar heat collector and the frame. CONSTITUTION:One end of each of a pair of support rods 3 and one end of each of a pair of support rods 4 are rotatably fixed to a solar heat collector 1 and the other ends of both of the support rods 3 and 4 are rotatably fixed to a frame 2 so that a linkage mechanism is formed of the solar heat collector 1, the frame 2, the support rods 3 and the support rods 4. Numeral 5 designates a drive device for turning the pair of support rods 3 up and down and numeral 6 designates a solar battery. When the pair of support rods 3 are turned to rise up by the drive device 5, it is possible to make the angle of inclination of each of the support rods 3 at about 10 deg.. In other words, assuming that the angle of inclination of the roof is, for example, 30 deg., it is possible to change continuously the angle of inclination of the heat collecting surface of the heat collecting device in the range of 20-45 deg.. |
