Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a method for mounting a solar collector on a conical roof or a roof having an inclined ridgeline and accommodating the solar collector in a transparent capsule. Regarding technology.

Prior Art The present applicant has previously proposed a solar light collection device in which sunlight is focused by a lens or the like, introduced into a light guide, and transmitted to any desired location through the guide for illumination or other uses. Ta.

FIG. 4 is a perspective view for explaining an example of a sunlight collecting device previously proposed by the present applicant. In the figure, 1 is a cylindrical base, 2 is a transparent dome-shaped head, These constitute a capsule 3 for a solar collector, and in use, a solar collector 10 is housed within the capsule 3 as shown. This sunlight collecting device 10 includes a large number of concentrically arranged lenses 1 for concentrating sunlight, for example, 19 lenses, a sunlight direction sensor 12 for detecting the direction of the sun, and a solar light direction sensor 12 for detecting the direction of the sun. Support frame 13 held in
, a first motor 15 for rotating these in the direction of arrow A, a support arm 16 that supports the lens 11 to the motor 5, and a support arm 16 disposed perpendicular to the rotation axis of the motor 15. It has a rotating shaft 17, a second motor (not shown), etc. for rotating the rotating shaft] 7 in the three directions of the arrow (1), and detects the direction of the sun with the sunlight direction sensor 12, and receives the detection signal. The first and second motors are controlled by R1u so that the lens 11 always points toward the sun, and the lens 1
The sunlight focused by 1 is introduced into a large number (19 in the example of FIG. 1) of optical conductor cables (not shown) whose light-receiving ends are arranged at each focal position of the lens, and the light guide cables It is possible to transmit the information to any desired location.

As mentioned above, the solar light collecting device is used housed in a transparent capsule, and as is clear from FIG. Two solar panels are prepared and used by joining them at the flange, but when the sunlight that enters the solar collector passes through the flange, it is disturbed by the flange. Light could not be collected efficiently.

In addition, when manufacturing semicircular transparent capsules such as -3='', for example, blow molding is performed by blowing heated and pressurized air, or in that case, the area near the flange is thick and the area near the top is thick. As a result, the refractive index of light differs in each part, making efficient collection of sunlight impossible.

The M-type present invention was made in view of the above-mentioned circumstances,
In particular, the purpose of this invention is to provide a sunlight collecting capsule that has a uniform thickness throughout, is easy to manufacture, and can effectively collect sunlight.

Structure-----I muttered.

FIG. 1 is a diagram for explaining the usage state of the solar power collecting capsule according to the present invention, and in the figure, 2o indicates an example of a building in which the solar light collecting device capsule according to the present invention is used; The roof portion 21 of the building is configured in a conical shape,
Alternatively, as shown in the figure, at least one slanted ridgeline portion 22 is provided on the surface including the south side. Although a pyramid-shaped roof is shown in FIG. 1, a conical roof may also be used. In the present invention, the solar collector is installed at the top or ridgeline of the roof as described above; If it is installed on a ridgeline, it is housed in a conical transparent capsule 30, and when it is installed on a ridgeline, it is housed in a cylindrical transparent capsule 40. Inside these capsules 30 or 40, it is possible to house a solar collector 10 as shown in FIG. For example, in the case of the conical capsule 30, as shown in FIG. Array 51a.

51 b, 51 c, 51 d, etc. 5 These lens arrays 51 a to 51 d are rotatably supported around the central axis 50 either integrally with the central axis 50 or independently for each lens array, and are are supported rotatably about a horizontal axis perpendicular to the central axis 50, either integrally or independently for each lens array, whereby the whole can be rotated simultaneously or independently for each lens array. 2 orthogonal
It is rotatably supported around an axis and rotates to follow the movement of the sun. A large number of lens arrays having the same configuration can be arranged within the cylindrical body 40, but in this case, each lens array can have the same size, and as shown in FIG. There is no need for the width of the lens array to decrease upwardly as in the embodiment shown.

FIG. 3 is a side view showing an example of the lens array, in which 51□, 51°...51[l is a lens,
These lenses 511 to 5111 may be arranged on the same plane, or may be arranged in an arc along the arc of a cylinder or cone as shown in the figure. According to the present invention, since the transparent capsule 30 has a conical shape and the transparent capsule 40 has a cylindrical shape, these capsules can be formed by cutting, heating and bending a transparent plate of uniform thickness, adhering, etc. As a result, the thickness of the capsule can be made uniform over the entire capsule, and diffuse reflection, diffuse refraction, etc. at the transparent capsule portion are eliminated, and sunlight can be collected efficiently. Of course, the upper ends of the conical capsule 30 and the cylindrical capsule 4o are sealed, and rainwater and the like will not enter the capsules from there.

EFFECTS As is clear from the above description, the present invention effectively utilizes the special roof structure of a building, in other words, it matches the roof structure of the building and installs the solar collector on the building. In addition, the transparent capsule that houses the solar collector has a shape that matches the roof structure of the building, and the thickness of the capsule is uniform throughout. To provide a capsule for a solar light collecting device that can efficiently collect sunlight because it can be used as a roof, and that can enhance the beauty of the roof and make it a symbol of the building. Can be done.
