JPS5819659A - Capsule for sun light collecting device - Google Patents

Abstract

PURPOSE:To enhance the collecting efficiency of the sun light by a structure wherein the crown part of the capsule and the connecting part to the basic part are joined into one body on a plane with the predetermined inclination to the horizontal axis. CONSTITUTION:Flanges 2a and 3a, which connect the crown part 2 of the capsule 4 housing a sun light collecting device 10 threwithin and the connecting part 3 to the basic part 1 with each other, are joined into one body on a plane inclined to the horizontal axis at the predetermined angle. Owing to the structure as described above, because the dust gathered on the flanges 2a and 3a is allowed to be washed off by rain and the snow heaped on the flanges 2a and 3a is allowed to be slided down along the slope of the flanges 2a and 3a, the interception of the sun light by dust, snow or the like is eliminated.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a capsule for a solar collector for protecting the solar collector from wind, rain, dust, and the like.

FIG. 1 is an overall perspective view showing an example of the solar light collection device that Hideto Motoide proposed earlier. In the figure, 1 is a cylindrical base portion, 2
3 is a dome-shaped head of a transparent body, and 3 is a connecting part of a transparent body that connects the base part and the head, and these k constitute a capsule 4 for a sunlight collecting device, and when in use, the capsule 4 A sunlight collecting device 10 is housed therein as shown.

This sunlight collecting device 10 includes a large number of lenses 11 (for example, 7 lenses, 19 lenses) for concentrating sunlight, a sunlight direction sensor 12 for detecting the direction of the sun, and these integrally. A support frame 13 for holding, a first rotation shaft 14 for rotating the support frame 13, a first motor 15 for rotating the first rotation shaft 14, and the lens 11 to the motor 1.
5, a second rotating shaft 17 arranged perpendicular to the first rotating shaft 14, and a second motor (not shown) that rotates the second rotating shaft 17. The sunlight direction sensor 12 detects the direction of the sun, and the detection signal controls the first and second motors so that the lens 11 always faces the sun, and the sunlight focused by the lens 11 is controlled so that the lens 11 always faces the sun. Light is introduced into a light guide cable (not shown) whose light receiving end is disposed at the focal position of the lens, and transmitted to any desired location through the light guide cable for various uses such as indoor lighting. There is. Therefore, in order to protect the solar light collecting device from wind, rain, dust, etc. in the solar light collecting device as described above, the solar light collecting device is housed in a capsule 4 as shown in FIG. However, in conventional capsules, the head 2 is connected to the connecting part 3.
Since the flanges 2a and 3a connecting the two are horizontal, there are drawbacks such as dust adhering to the flanges, and when traveling to foreign countries, snow may accumulate and sunlight cannot be collected efficiently.

The present invention has been made in order to solve the above-mentioned drawbacks of the prior art, and as shown in FIG. The flanges 2a and 3a are arranged at an angle.

Therefore, according to the present invention, since the flange portion is arranged at an angle, dust accumulated on the flange can be easily washed away when it rains, and snow accumulated on the flange can be easily washed away. Since it easily slides down along the slope of the flange, sunlight is not blocked by dust, snow, etc. accumulated on the flange, and sunlight can be collected efficiently at all times.
