One of these system is disclosed in Japanese Patent Laid Open Publication No. 58-193510, amongst other sources. It is an additional object of the current invention to provide such a sun tracking device can reduce the drive power necessities for driving the rotatable desk to an especially low level, and might support and drive the rotatable desk with a simple structure. FIGS. 4(a) to 4(c) are illustrative drawings for describing the sun tracking action of the first most popular embodiment sun tracking iTagPro device. FIG. 5 is a facet view thereof. FIGS. 6(a) to 6(c) are plan view for illustrating the sun monitoring motion of the second most well-liked embodiment sun tracking device. FIG. 8 is a plan view thereof. FIG. 9 is a aspect view thereof. FIG. 10 is a plan view displaying a solar power generating system which incorporates a fifth most well-liked embodiment of the solar tracking device in accordance with the present invention.
FIGS. 1 via four show a photo voltaic energy producing system with incorporates the primary most well-liked embodiment of the solar tracking device of the current invention, which is constituted to be arranged on a body of water resembling a sea or a lake. This fixed shaft 1 is erected in a generally perpendicular orientation with its base end buried within the lake or sea bottom, iTagPro USA and is reinforced by man wires 3 extending slantingly downwards from a mid level of the fixed shaft 1, whose other ends are engaged to the lake or sea bottom. 2 is internally outfitted with a floatation force offering means which may embody a set of buoys or the like, or is externally supplied with a floatation force providing means which could also be a set of buoys made of urethane, rubber or the like and thereby is induced to float on the floor of the water in a generally horizontal orientation whereas being substantially freely rotatable in a horizontal aircraft in regards to the vertical central axis of the mounted shaft 1, with a specific amount of play of the rotatable desk 2 relative to the central axis of the mounted shaft 1 being allowed, iTagPro shop both in the sideways direction, within the longitudinal course and with respect to angular turning relative to the fixed shaft 1, as a way to compensate for transitory undulations comparable to waves of the water surface which trigger wobbling of the rotatable table 2 with respect to the mounted shaft 1 by a sure wobbling range.
2 is provided with a plurality of solar cell arrays 6 equivalent to 6a, 6b and 6c which are used for power technology, and further carries a pair of solar cell arrays 7 and iTagPro device eight which serve as sensors, and the circumference of the rotatable table 2 is additional supplied with two tracking drive mechanisms 11 and 12, which respectively comprise screws 10a and 10b and DC motors 9a and 9b respectively drivingly coupled thereto. 6a, 6b, iTagPro USA and 6c are arranged on the rotatable table 2 in a mutually spaced manner with their lengthy axes being considerably parallel, and, as can be seen later, for an exemplary one of these methods put in in the northern hemisphere, are directed typically to the south with a certain inclination to the east or itagpro locator to the west of south in line with the position of the solar, being swiveled a couple of vertical axis as the rotatable table 2 turns about the axis of the mounted shaft 1 in line with the motion of the solar as can be seen later.
6a, 6b and 6c is appropriately adjusted in response to the latitude of the location when the solar energy generating system is put in. 7 and eight are organized in a symmetrical manner on either side of the axis of symmetry of the construction, which is perpendicular to the long axes of the photo voltaic cell arrays 6a, 6b and anti-loss gadget 6c and passes by the rotational shaft 4, and the photo voltaic cell arrays 7 and 8 are angled for instance at an angle of about 30° to the axle of symmetry, as exemplarily shown in FIGS. 2 and 3, with their mild receiving surfaces faced inwardly. 7 and 8 may be canted or sloped, so as to obtain a good and ample amount of solar mild, depending upon the latitude of set up of the photo voltaic power producing system. 10a on the rotatable table 2 is corresponding to to show the rotatable desk 2 within the anticlockwise route as seen within the figure, while alternatively the rotational pressure exerted by the action of the screw 10b on the rotatable table 2 is similar to to show the rotatable desk 2 in the clockwise direction as seen within the determine.
