Abstract

PURPOSE:To send the solar rays to a shady place from right above all the time by tracking the sunshine rays all the time throughout the whole year and the duration of sunshine and operating a reflection mirror based on the information. CONSTITUTION:When a driving shaft 1 is rotated at an equal speed to make one turn a day, a sun-directed shaft 3 swivels to face the sun throughout the duration of sunshine and the angles of the swivel of a reflection mirror supporting shaft 7 and the rotation of a perpendicular shaft 6 correspond to the azimuth angle of the sun; and the surface of the reflection mirror supporting shaft 7 is directed to the sun all the time and a reflection mirror fixed in parallel to the reflection mirror supporting shaft 7 sends the solar rays perpendicularly downward. For the purpose, an angle sensor 6 detects the angle of rotation of the perpendicular shaft 5 and an angle sensor 8 detects an angle alpha respectively; and those angles are fed back to a rotary driving device 2 to direct the sun-directed shaft 3 to the sun. Consequently, the solar rays are reflected by the reflection mirror and sent perpendicularly downward throughout the whole year and the duration of sunshine.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a solar ray intake device suitable for introducing solar radiation into a place subject to solar damage, such as a courtyard of a high-rise building.

[Conventional technology]

There tends to be insufficient sunlight in the courtyards of high-rise buildings, or near the ground between buildings where the line spacing between the holes is narrow, so it is desirable to develop a device that can send the necessary solar radiation to places that are subject to such sunlight interference. It will be done.

[Problem that the invention seeks to solve]

The present invention was proposed in view of these circumstances, and
To provide a solar ray intake device that can always track sunlight throughout the year and throughout the sunshine hours, and can always send sunlight to a shaded place from directly above by operating a reflector based on the information. With the goal.

[Means for solving problems]

To this end, the present invention provides an inclined drive shaft that is installed obliquely with an angle of inclination equal to the latitude of the installation point with respect to the horizontal and rotates at a constant speed of one rotation per day, and one end of which is pivoted to the lower end of the drive shaft. a sun pointing axis extending at a changeable angle to the tilted drive shaft so that the other end always points at the sun throughout the seasons; a vertical shaft that rotates in synchronization with the tilting drive shaft; one end is pivotally supported by the vertical shaft, the other end extends across the sun-directing axis, and the pivot point of the tilting drive shaft and the sun-directing axis is the apex; A reflector support shaft that forms the base of an isosceles triangle with a reflector fixed to the upper end, and a reflector support shaft provided at the intersection of the sun pointing axis and the reflector support shaft, and both shafts are pivoted. It is characterized by comprising a shaft joint that allows the sun pointing shaft to slide with respect to the reflecting mirror support shaft.

[For production]

With the above configuration, it is possible to obtain a solar ray intake device that can constantly track sunlight throughout the year and throughout the daylight hours, and can always send sunlight to a shaded place from directly above by operating a reflector based on the information. Can be done.

〔Example〕

An embodiment of the present invention will be explained with reference to the drawings. Fig. 1 is a perspective view thereof, Fig. 2 is an explanatory diagram of the principle of Fig. 1, Fig. 3,
FIG. 4 is a schematic diagram of a reflecting mirror device operated according to the information of the device shown in FIG. 1, respectively.

First, in Figs. 1 and 2, reference numeral 1 denotes a drive shaft that is inclined with respect to the horizontal at an angle ψ equal to the latitude of the installation point of this device and is rotatably supported. tied together.

Reference numeral 3 denotes a sun pointing shaft having an appropriate length whose intersecting angle θ with respect to the driving shaft 1 can be changed so that one end is pivotally connected to the lower end O of the drive shaft 1 and the other end B always points toward the sun. is set by the angle sensor 4 throughout the year, such as OB' at 665° in the summer solstice, OB# at 1135° in the winter solstice, and OB at 90° on the equinox.

Reference numeral 5 designates a vertical shaft of an appropriate length that is vertically supported directly below the pivot point O between the drive shaft 1 and the sun pointing shaft 3, and is rotatably supported for its own axis. An angle sensor 6 is provided oppositely.

Reference numeral 7 denotes a reflector support shaft which is spanned between the sun pointing axis 3 and the vertical axis 5 at points E and D which are equidistant from the pivot point O, respectively. It engages with a shaft joint that also allows sliding of the sun pointing shaft 3 in the DE' direction. Reference numeral 8 denotes an angle sensor that indicates the angle α between the mirror support shaft 7 and the vertical axis 5. Reference numeral 9 denotes an L-shaped rotation auxiliary member whose lower end is fixed to the vertical shaft 5 and whose upper end guides the sun pointing shaft 3 in the vertical direction.

In such a device, as shown in Figure 2, OB always points toward the sun, and triangle OED has one side DE.
Since it is an isosceles triangle with the base being , the sunlight that enters from the reflecting mirror fixed on the side DE is directed vertically downward.

Therefore, when the rotary drive device 2 rotates the drive shaft 1 at a constant speed of 15°/hr, that is, one rotation per day, the sun pointing shaft 3 rotates and points in the direction of the sun at the central shrine during the sunshine hours, and accordingly Therefore, the angle of rotation of the reflector support shaft 7 and the rotation of the vertical axis 5 are not the azimuth angle of the sun, so that the surface of the reflector support shaft 7 always faces the sun direction, and is parallel to the reflector support shaft 7. A fixed reflector always sends sunlight vertically downward. Therefore, the angle sensor 6 measures the rotation angle of the vertical axis 5,
If the angle α is detected by the angle sensor 8 and always fed back to the rotary drive device 2 to direct the sun direction axis 3 toward the sun, the sun's rays will be reflected by the reflector throughout the year and during the sunshine hours, and will be directed downward in the vertical direction. It will be sent.

The rotation of the sun pointing axis 3°, the reflection mirror support shaft 7, and the rotation of the vertical axis 5 as the drive shaft 1 rotates is controlled by the rotation auxiliary member 9.
It is done properly.

Next, an example of a separate reflector device that is operated based on the angle information detected by the angle sensors 6 and 8 will be explained with reference to FIGS. 3 and 4. In FIG. A reflecting mirror support 12 is pivotally mounted on the top so as to maintain the angle α, and a reflecting mirror 13 is installed parallel to this, and the angle α and the rotation angle information of the vertical axis 5 are processed by electrical means or the like. and transmitted.

In addition, in FIG. 4, a reflector support 12 is pivoted on a similarly rotatable vertical rotation support 11 so as to maintain an angle β=90°−α, and a large number of reflectors 13 are mounted on this. It is installed for direct firing, and similarly, the angle α and the rotation angle information of the vertical shaft 5 are processed and transmitted by electrical means or the like.
