One of these system is disclosed in Japanese Patent Laid Open Publication No. 58-193510, amongst other sources. It is a further object of the present invention to provide such a solar tracking device can reduce the drive energy requirements for driving the rotatable desk to an extremely low level, and might assist and drive the rotatable desk with a simple construction. FIGS. 4(a) to 4(c) are illustrative drawings for describing the sun tracking motion of the first most popular embodiment solar Tagsley tracking card device. FIG. 5 is a side view thereof. FIGS. 6(a) to 6(c) are plan view for illustrating the solar monitoring motion of the second most well-liked embodiment solar tracking device. FIG. Eight is a plan view thereof. FIG. 9 is a side view thereof. FIG. 10 is a plan view exhibiting a solar energy generating system which includes a fifth preferred embodiment of the sun tracking device in keeping with the present invention.
FIGS. 1 through 4 present a photo voltaic power generating system with incorporates the primary preferred embodiment of the solar tracking device of the current invention, which is constituted to be organized on a physique of water corresponding to a sea or a lake. This mounted shaft 1 is erected in a typically perpendicular orientation with its base finish buried within the lake or sea backside, and wallet tracking solution is strengthened by guy wires three extending slantingly downwards from a mid point of the mounted shaft 1, whose other ends are engaged to the lake or sea bottom. 2 is internally outfitted with a floatation force providing means which can include a set of buoys or the like, or is externally provided with a floatation pressure offering means which may be a set of buoys made of urethane, rubber or the like and thereby is induced to float on the surface of the water in a generally horizontal orientation whereas being substantially freely rotatable in a horizontal airplane in regards to the vertical central axis of the fixed shaft 1, with a specific amount of play of the rotatable desk 2 relative to the central axis of the fastened shaft 1 being allowed, Tagsley each within the sideways direction, within the longitudinal direction and with respect to angular turning relative to the fixed shaft 1, with the intention to compensate for transitory undulations akin to waves of the water floor which trigger wobbling of the rotatable desk 2 with respect to the fixed shaft 1 by way of a certain wobbling vary.
2 is supplied with a plurality of solar cell arrays 6 resembling 6a, 6b and 6c which are used for power era, and additional carries a pair of photo voltaic cell arrays 7 and eight which serve as sensors, and the circumference of the rotatable desk 2 is additional provided with two monitoring drive mechanisms eleven and 12, which respectively comprise screws 10a and 10b and DC motors 9a and Tagsley tracking card 9b respectively drivingly coupled thereto. 6a, 6b, and 6c are organized on the rotatable table 2 in a mutually spaced method with their lengthy axes being considerably parallel, and, as shall be seen later, for an exemplary one of these methods installed within the northern hemisphere, are directed typically to the south with a certain inclination to the east or to the west of south in accordance with the position of the solar, being swiveled a few vertical axis because the rotatable desk 2 turns concerning the axis of the mounted shaft 1 according to the movement of the sun as might be seen later.
