This invention relates to the improvement of the solar collector which focuses sunlight by a lens system, and introduces this connected sunlight into an optical conductor cable, and transmits it to arbitrary places.

In more detail, the present invention relates to a solar collector of the above type which makes it possible to introduce connected sunlight into a photoconductor cable with high efficiency.

Recently, interest in the use of solar energy in the energy-saving era is increasing.

The present applicant has already made various proposals with an early focus on the effective use of solar energy.

The most effective use of solar energy is to use solar energy as direct light energy, that is, without converting it into other forms of energy such as electricity or inferior.

Therefore, the present applicant has proposed to focus solar energy, introduce it into the optical conductor cable, and guide the illumination where necessary through the optical conductor cable to provide it to the illumination.

In this way, when the solar energy is transmitted using the optical conductor cable and illuminated with the solar energy, the conversion loss is eliminated and the solar energy can be used most efficiently.

However, it is not possible to introduce all the concentrated solar energy into the photoconductor cable and therefore the efficiency is quite low.

The present invention has been made in view of the drawbacks of the prior art as described above.

That is, the present invention provides a first adjustment mechanism capable of moving the light receiving end section of the optical conductor in the optical axis direction of the lens system, and a second adjustment mechanism that is movable in two vertical directions of the optical axis and perpendicular to each other. The mechanism to match the light receiving end surface of the conductor cable is to solve the drawbacks of the prior art.

The advantage of the present invention is to solve the drawbacks of the prior art by making the positioning operation easy and stable when the light receiving end surface of the optical conductor cable is aligned with the focal position of the lens system and ensuring the fixing after the alignment.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is an overall configuration diagram of a conventional solar collector to which the present invention is applied.

In FIG. 1, the solar collector 1 includes a lens system 2 for focusing sunlight L, a frame 3 and a bottom plate 4, and a lens system 2 for protecting and protecting the lens system 2. It is equipped with the optical conductor cable 5 which guides the sunlight converging by ().

The sunlight focused by the lens system 2 is transmitted to a desired place through the optical conductor cable 5 and provided for use.

In the solar collector as described above, if the light-receiving end surface 5a of the optical conductor cable 5 does not coincide with the focal position of the lens system 2, the solar light focused by the lens system 2 is collected. It cannot be efficiently introduced into the optical conductor cable 5, and therefore, the matching operation of the correct position of the light receiving end surface 5a was very large.

In addition, even when both of the positions were correctly matched at the time of assembly work, if the fixation after fixing the position was not firm, the repositioning work to adjust the position was very difficult and large, because the position was displaced by the electric or the like during use of the apparatus.

2 is a bottom view for explaining an embodiment of a solar collector according to the present invention.

This solar collector 1 has a hexagonal Fresnel lens 2 and a frame 3 for protecting and supporting the Fresnel lens 2.

The sunlight focused by the Fresnel lens 2 is formed in the center of the light shielding plate 6, as in the solar collector 1 of FIG. 1, in the hole 7 to which the optical conductor cable 5 is attached. Is delivered. In addition, as shown in FIG. 3, the light receiving end surface 5a of the optical conductor cable 5 is arranged in the hole 7.

Thus, the sunlight focused by the Fresnel lens 2 is guided to the optical conductor cable 5 and transmitted to the desired place through the optical conductor cable 5 and provided to the illumination. As described above, in the solar collector 1 having such a structure, it is necessary to accurately match the light receiving end surface 5a of the optical conductor cable 5 to the focal point of the lens system 2.

The present invention allows for easy, safe and accurate alignment work.

In FIG. 2, the bolt shafts 8a and 8b are arranged parallel to each other at the bottom of the solar collector 1 and fixed to the frame 3.

The bolt shafts 8a and 8b are provided with cylinders 9a and 9b that can move the bolt shafts 8a and 8b in the direction of the arrow A, respectively.

In addition, two bolt shafts 10a, 10b are disposed at right angles and parallel to the bolt shafts 8a, 8b between the cylinders 9a, 9b. These bolt shafts 10a and 10b are also provided with cylinders 11a and 11b which are movable in the direction of the arrow B in the respective bolt shafts 10a and 10b.

The bolt shafts 8a and 8b and the cylinders 9a and 9b and the bolt shafts 10a and 10b and the cylinders 11a and 11b respectively constitute a second adjustment mechanism.

A light shielding plate 6 having a hole 7 into which the light receiving end surface 5a of the optical conductor cable 5 is fitted is integrally attached to these cylinders 11a and 11b.

Therefore, by adjusting the cylinders 9a and 9b in the direction of the arrow A and / or the cylinders 11a and 11b in the direction of the arrow B, the position of the hole 7 of the light shielding plate 6 is adjusted. In the vicinity of the focal point of the lens system 2, it can be adjusted to an arbitrary position on a plane parallel to the ground.

In the device of the present invention, when the cylinders 9a and 9b are moved in the direction of the arrow A, the nuts 12a and 12'a on the bolt shaft 8a and the nuts on the bolt shaft 8b ( The cylinders 9a and 9b can be moved in the direction of the arrow A in the state where 12b) and 12'b are unwound.

When the cylinders 11a and 11b are to be moved in the direction of the arrow B, the nuts 13a and 13'a on the bolt shaft 10a and the nuts 13b on the bolt shaft 10b are also provided. The cylinders 11a and 11b can be moved in the direction of the arrow B in the state of releasing 13'b.

After allowing the cylinders 9a, 9b, 11a, and 11b to be movable, the positions of the holes 7 of the light shielding plate 6 are adjusted to desired positions, and the nuts 12a, 12'b, By tightening the cylinders 9a, 9b, 11a, and 11b with 12b, 12'b, 13a, 13a ', 13b, and 13'b, The cylinders 9a, 9b, 11a, and 11b are firmly fixed by being hardened by two nuts, respectively.

Therefore, the position does not change even after the alignment.

FIG. 3 is a cross sectional view taken along line III-III in FIG. 2, and is a cross sectional view when the optical conductor cable 5 is disposed in the hole 7 of the light shielding plate 6 shown in FIG. The pedestal 14 is integrally attached to the cylinders 11a and 11b, and thus the pedestal 14 is movable in the directions of arrows A and B shown in FIG. The cylinder 15 is for protecting and supporting the optical conductor cable 5 so that a movement to the arrow C direction is possible. On the outer circumference of the cylinder 15, there are screws screwed into the nuts 16 and 17, and grooves 18 engaging with protrusions (not shown) of the pedestal 14 are dug in the outer axial direction. have. As the said cylinder 15 and the nuts 16 and 17, a 1st adjustment mechanism is comprised.

Therefore, when the nuts 16 and 17 are loosened, the cylinder 15 is guided to the groove 18, and it will be in the state which can move to the arrow C direction. When the cylinder 15 is tightened with the nut 1 and 17 positioned at the desired position, the cylinder 15 is securely fixed at that position, and the position is rarely changed after that.

An optical conductor cable 5 is inserted into the cylindrical body 15, and the light receiving end 5a of the optical conductor cable 5 protrudes through the hole 7 to the upper surface of the light shielding plate 6, in this way. The sunlight focused on the lens system 2 is introduced into the optical conductor cable 5 through the light receiving end surface 5a.

The sheath of the optical conductor cable 5 is cut off at the end thereof so that only the fiber portion 5b remains.

The fiber portion 5b is fixed by the fixing member 19 (protective support member) to constitute the end of the optical conductor cable 5.

A spiral is formed on the upper outer periphery of the fixing member 19, and the rotation preventing mechanism 19a is formed at the lower portion of the fixing member 19. The upper spiral portion of the fixing member 19 is fixed to the cylinder 15 by a nut 20.

In this way, when the end of the optical conductor cable 5 is fixed to the cylinder 15, the cylinder 15 can move in the direction of the arrow C as described above, so that the light receiving end surface of the optical conductor cable 5 ( 5a) can be adjusted at any position in the direction of arrow C. FIG.

Therefore, the adjustment of the light receiving end end 5a of the optical conductor cable 5 can be precisely matched to the focal position of the lens system 2 by the adjustment in the directions of the arrows A and B.

4 is a cross-sectional view showing another embodiment of the present invention.

In the case of FIG. 2 and FIG. 3, the light shielding plate 6 having the hole 7 into which the light receiving end surface 5a of the optical conductor cable 5 is fitted is integrally attached to the cylinders 11a and 11b. The upper outer circumferential surface of the fixing member 19 is formed with a spiral, and the lower portion of the fixing member 19 is formed with an anti-rotation tool 19a, and the upper spiral portion of the fixing member 19 is a nut 20. It is fixed to 15.

Contrary to the above, in the other embodiment of FIG. 4, the light shielding plate 6 is not attached to the cylinders 11a and 11b, but is attached to one of the nut 10 or the nut 17 by means of screwing or welding. (For example, the nut 16) is firmly fixed.

The cylinder 15 is formed with two holes in the longitudinal direction of its axis, and the screw that is screwed into the small diameter portion of the upper portion formed with the spiral in the fixing member 19 is formed in the upper inner wall which is the small diameter portion of the cylinder 15. It is.

Therefore, there is no necessity of matching the lower diameter with the large diameter in the fixing member 19 and the lower hole with the large diameter in the cylinder 15. It will be readily understood that the nut 16 can be tightened by simply rotating the light shield plate 6 by hand, and the nut 10, (FIG. 3) can be loosened.

As is apparent from the above description, according to the present invention,

In aligning the light receiving end surface of the optical conductor cable to the focal point of the lens system, the three-lateral direction, which is perpendicular to each other, can be adjusted at one point close to the focal point of the lens system. Therefore, the adjustment work can be fairly easy.

Furthermore, since each adjustment member is fixed with a nut after the position is adjusted, there is no change in the position of the light receiving end section thereafter.

This is a significant effect of the present invention.

Although the present invention has been described in detail by way of example as described above, it will be readily understood that appropriate substitutions or changes are possible without departing from the spirit or basic scope of the present invention.
