Abstract

PURPOSE:To utilize solar energy while following up the momentarily varying altitude and direction of the sun and fixing the sun at a specific stationary point optically by using a sun altitude tracking mechanism equipped with solar batteries on the surface of a photodetecting plate which rotates around a horizontal axis in combination with a sun direction tracking mechanism. CONSTITUTION:The sun leaving the horizon increases in altitude and when its light becomes incident to the surface of the solar battery 8, a motor 5 rotates by its electromotive force to transmit its rotation through a gear 4 to a semicircular gear 3, rotating the photodetecting plate 2. When the sun starts decreasing in altitude from its highest point, the light is incident to the surface of a solar battery 9 and a motor 6 is therefore driven to rotate the photodetecting plate 2 in the opposite direction to the direction in the forenoon. A bearing stand 11 for those sun altitude tracking mechanisms is used in combination with the sun direction tracking mechanism having two solar batteries 20 and 21 and the photodetecting plate 2 is held at right angles to the sun light all the time.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device mechanism for tracking the ever-changing altitude and azimuth of the sun and optically fixing the sun at a fixed position.

Conventionally, the sun's energy has been subject to various limitations, such as the fact that the sun is always moving and never stands still, even though the sun's energy is a sluggish dog, and there are many problems in terms of its utilization technology.

The present invention aims to eliminate the inconvenience caused by the constant movement of the sun and the uneven optical angular relationship between objects on the ground and the sunlight, and to develop new fields of solar energy utilization. It provides an advantageous device mechanism that detects and tracks changes in direction and orientation using solar cells and reveals an optically stationary sun.

The figure will be explained starting with the solar altitude tracking mechanism. FIG. 1 is a front view illustrating the invention in detail. Figure 2 is a plan view of the main parts.

FIG. 8 similarly shows a side view of the main part. 1 is a cylindrical rotation axis, which serves as the rotation axis of the light receiving plate 2. 8 is a semicircular gear fixed to the back side of 2, meshing with gear 4 to rotate 2. 4
is operated by a motor 5, which is controlled by the electromotive force of a solar cell 8, and operates via an amplifier circuit 8' and a relay circuit 29. Since the detection function is performed by a solar cell, the present invention does not use the surface of the solar cell as a fire source, but uses electromotive force only when the solar device changes and tracking becomes necessary, which is one of the features of this device. It is one. When the sun, which has now left the horizon, increases in altitude and shines onto the surface of the solar cell 8, a slight electromotive force is generated in the solar cell 8. The electromotive force 8 passes through the amplifier circuit 8', activates the relay circuit 29, and rotates the motor 5. The number of revolutions 5 is reduced by a predetermined speed by a reduction gear 7 and transmitted to the gear 4. The hand rotates the light-receiving plate 2 by engaging the gear 8. Then, the light receiving plate 2 and the sunlight become perpendicular, and the rotation continues in the upward direction until no light enters the surface of the plate 8 and the power generation becomes zero.
Track solar altitude. When the altitude reaches its highest point at noon and begins to descend, light shines onto the surface of the solar cell 9. The electromotive force generated at 9 is amplified at 9' and operates on a relay circuit 80 to rotate the motor 6. The rotational speed of 6 is decelerated by 7 and transmitted to gear 4, which moves 8 and rotates the light receiving plate 2 in the opposite direction.

(Motors 6 and 5 are mounted so as to face each other with 7 in between. In this case, by fixing the rotating shaft and making it a common shaft, the direction of rotation of 7 can be reversed.) In other words, the 5th motor is raised in the morning. 6 will track the sun as it descends in the afternoon.

Next, a mechanism for tracking the horizontal solar direction will be explained.

The sun is always moving westward from the Earth's surface.

Assume now that the axis of rotation l and sunlight are perpendicular, that is, nine does not hit the surface of the solar cell 2o. Next, when the state changes and the sun moves and light shines on the surface of 20, an electromotive force is generated. This electromotive force operates the motor 16 through a second amplifier circuit and a relay circuit 31. The rotational force of 16 is decelerated by the reduction gear of 18, causing the pinion 14 to rotate at a low speed, and
slowly move along the interlocking circular racks 18 20
This continues until the electromotive force becomes zero, that is, the axis of rotation l and the sunlight become perpendicular. This operation is repeated from sunrise to sunset as long as there is sunlight, but on cloudy days or at night it stands still and does not operate.

Thirty-two solar cells are mounted on the upper part of the light receiving plate 2 with the battery side facing back. This device, which tracked the sun until sunset, captures the morning sun with the help of the solar cells.1゛ The electromotive force rotates motor 17 through 21' and 88, rotating this device eastward, and the morning sun and light receiving plate 2. Continue until it becomes vertical. In this case, the electromotive force to rotate 17 changes from 83 to 2
1, both solar cells 32 and 21 are connected in parallel as shown in the electrical circuit of FIG.

Next, let's talk about the solar taxiway.

The light receiving plate 2 is always kept perpendicular to the sunlight by the above-mentioned solar altitude and azimuth tracking mechanisms. That is, the sunlight incident from the sensor 22 is reflected and refracted by the plane lug 28 mounted at an angle of 45 degrees with the inside of the cylinder 2, and travels in the direction of the rotation axis.

The plane mirror 25 is mounted in the traveling direction of this reflected light, that is, on the extension of the rotation axis, with a spatial gap separated from the bearing 24.

By providing a gap, sunlight refracted at 28 enters 25 without interfering with the tracking movement of light receiving plate 2. In addition, since 25 is a plane mirror installed on the same bearing stand ll as 2, even if the direction of the sun changes and the bearing stand 11 rotates, 2
The sunlight refracted at B and traveling in the direction of the rotation axis l is always 25
It will be incident on . The light refracted vertically downward at 25 is reflected by a plane mirror 2 attached to the bottom plate of the vertically lower bearing stand 11 at 25.
6, it is refracted again and directed toward the center of the rotating shaft of the bearing stand 11. This refracted sunlight is further refracted and reflected by a 27-meter lens mounted inside the cylinder on the center line of the rotation @12, and is guided vertically downward in the cylinder. In other words, even if the position of the sun changes, the sun image can always be seen at a constant position, at the center of the horizontal rotation axis cylinder. 28 is a light guide and a plane mirror of the same size 25.26.2
This is to attach and fix the optical free space, that is, to prevent substances that may obstruct the propagation of light from entering. Therefore, the plane mirror fixing part can be omitted except for the part that fixes the plane mirror. 84
The pinion 14.15 shares the entire weight of the 18 circular racks and the mesh bearing pedestal 11 with the pinion 14.15. Further, reference numeral 24 is a cylindrical bearing part supported by the pillar IO, and uses a ball bearing or the like to smooth the rotation mechanism.

With the above configuration, the movement of the sun can be easily optically fixed by the device mechanism of the present invention, and the sun can be kept stationary throughout the day from sunrise to sunset. .

Although the explanatory diagram was drawn assuming a cross-sectional radius of about 80 mm as the cylindrical rotation axis, the size can be freely selected as necessary. When the sun stands still, it becomes easy to introduce a large amount of light and calories into buildings, basements, etc. by catadioptric refraction of several plane mirrors. In addition, by using multiple devices and superimposing the sunlight in one place, it is possible to use solar energy with high efficiency, which has a great effect.
