Description

Description: TECHNICAL FIELD The present invention relates to a solar ray intake device suitable for taking in sunlight to a place such as a courtyard of a high-rise building which is subject to sunshine damage.

[Conventional technology]

Sunlight tends to be insufficient in the inner courtyards of high-rise buildings or near the surface between buildings with narrow north-south pitches. Therefore, it is desirable to develop a device for sending necessary solar radiation to a place where such sunlight is impaired.

To this end, the present invention provides an inclined drive shaft that is installed at an inclination angle equal to the latitude of the installation point with respect to the horizontal and that rotates at a constant speed at one rotation per day, and one end is pivotally supported at the lower end of the drive shaft. The other end is vertically rotatably supported immediately below the sun directional axis extending at a crossing angle that can be changed with respect to the tilt drive axis so as to always point to the sun throughout the four seasons, and the fulcrum of the tilt drive axis and the sun directional axis. A vertical shaft that rotates in synchronization with the tilt drive shaft, one end of which is pivotally supported by the vertical shaft and the other end of which extends so as to intersect with the sun-direction axis and which has apexes of the tilt drive shaft and the sun-direction axis. When the bottom of an isosceles triangle is formed and a reflector is fixed to the upper end of the reflector, the reflector support shaft is provided at the intersection of the sun directing axis and the reflector support shaft. A shaft coupling that allows the sun-oriented shaft to slide on the reflecting mirror support shaft. And characterized in that it comprises a.

[Work]

With the above-described configuration, to obtain a sun ray intake device that can constantly track the sun ray through the year and sunshine hours and always send the sun ray to the shaded place from directly above by operating the reflecting mirror based on the information. You can

〔Example〕

An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view thereof, FIG. 2 is an explanatory view of the principle of FIG. 1, FIG.
FIG. 4 is a schematic view of a reflecting mirror device operated by the information of the device of FIG.

First, in FIGS. 1 and 2, reference numeral 1 denotes a drive shaft that is tilted with respect to the horizontal at an angle equal to the latitude of the installation location of the device and is pivotally supported so as to be rotatable. ing. Reference numeral 3 denotes a sun directing axis having an appropriate length with which the intersection angle θ with respect to the drive shaft 1 can be changed so that one end is pivotally attached to the lower end O of the drive shaft 1 and the other end B is always directed to the sun. Summer solstice 66.5 ° OB ′, winter solstice 113.5 ° OB ″, cluster amaryllis 9
It is set by the angle sensor 4 throughout the year such as 0 degree OB.

Reference numeral 5 is a vertical shaft that is vertically supported immediately below a pivot point O between the drive shaft 1 and the sun-oriented shaft 3 and is rotatably supported about its own axis. The sensor 6 is provided opposite.

Numeral 7 is a reflecting mirror support shaft which is passed and pivoted between points E and D equidistant from the pivot point O on the sun directing axis 3 and the vertical axis 5, respectively. Sun axis 3
It is engaged by a shaft joint that can also slide in the DE 'direction. An angle sensor 8 indicates an angle α between the reflecting mirror support shaft 7 and the vertical shaft 5. Reference numeral 9 is an L-shaped rotation assisting member whose lower end is fixed to the vertical shaft 5 and which guides the sun directional shaft 3 in the vertical direction at the upper end.

In such a device, as shown in FIG. 2, OB is always pointing toward the sun, and the triangle OED is an isosceles triangle with one side DE as the base, so that the reflection fixed on the side DE The sun ray L incident from the mirror faces vertically downward.

Therefore, when the drive shaft 1 is rotated by the rotary drive device 2 at a constant speed of 15 ° / hr, that is, one rotation per day, the sun-oriented shaft 3 turns and always points in the direction of the sun during the sunshine time, and reflects accordingly. The angle of turning of the mirror support shaft 7 and rotation of the vertical shaft 5 becomes the azimuth angle of the sun, and the surface of the reflector support shaft 7 always faces the sun azimuth, and the reflection fixed to the reflector support shaft 7 in parallel. The mirror will always send the sun's rays down vertically. Therefore, if the angle sensor 6 detects the rotation angle of the vertical axis 5 and the angle sensor 8 detects the angle α, and this is constantly fed back to the rotation driving device 2 and the sun-oriented axis 3 is directed to the sun, the sun rays will be emitted for a year. During the daylight hours, it is reflected by the reflector and sent vertically downward.

The rotation assisting member 9 appropriately rotates the sun-oriented shaft 3, the reflecting mirror support shaft 7, and rotates the vertical shaft 5 in accordance with the rotation of the drive shaft 1.

Next, an example of the separately placed reflecting mirror device operated based on the angle information detected by the angle sensors 6 and 8 will be described with reference to FIGS. 3 to 4, and in FIG. The reflecting mirror support 12 is pivotally mounted on the upper side so as to maintain the angle α, and the reflecting mirror 13 is installed in parallel therewith, and the angle α and the rotation angle information of the vertical axis 5 are processed by electrical means or the like. And then transmitted.

Further, in FIG. 4, a reflector support 12 is pivotally mounted on a vertically rotatable support 11 which is also rotatable so as to maintain an angle β = 90 ° −α, and a large number of reflectors 13 are attached thereto. They are installed orthogonally, and similarly, the angle α and the rotation angle information of the vertical shaft 5 are processed by electric means or the like and transmitted.

In short, according to the present invention, an inclined drive shaft that is installed obliquely with respect to the horizontal at an inclination angle equal to the latitude of the installation point and rotates at a constant rotation speed of one rotation per day, and one end is pivotally supported at the lower end of the drive shaft. And the other end is vertically pivoted directly below the pivot axis of the sun drive axis and the sun drive axis extending at a changeable intersection angle with the tilt drive axis so that the other end is always directed to the sun throughout the four seasons. And a vertical shaft that rotates in synchronization with the tilt drive shaft, one end of which is pivotally supported by the vertical shaft and the other end of which extends so as to intersect with the sun directing shaft and the pivotal points of the tilt drive shaft and the sun directing shaft. When the base of the isosceles triangle having the apex is formed and the reflector support shaft having the reflector fixed to the upper end, and both shafts provided at the intersection of the sun directing axis and the reflector support shaft are pivotally attached. It is also allowed to slide the sun-oriented axis on the reflecting mirror support axis. By equipped with a shaft against the hand that,
