JPS5819658A - Capsule for sun light collecting device - Google Patents

Abstract

PURPOSE:To improve the maintainability of the capsule by a structure wherein a door for going in and out capable of opening and closing is provided at the basic part of the capsule. CONSTITUTION:In the capsule 3 consisting of the cylindrical basic part 1, a dome-shape head part made of transparent body and the like, the door 20, through which for a man can go in and out and which is capable to open and close, is provided at the basic part 1. Owing to the structure as mentioned above, the adjustment of the adjusting equipment 19 of the sun light collecting device 10 housed within the capsule 3 turns to be possible and the light receiving end of an optical fiber can easily be brought in agreement with the focal point of a sun light condensing lens even after the installation of the capsule to its location.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement of a capsule for a solar collector for protecting the solar collector from wind, rain, dust, etc., and particularly,
The base of the capsule is provided with an entrance/exit door that can be opened and closed, allowing the user to enter the capsule and adjust the sunlight collection device.

Figure 1 is a perspective view showing an example of a capsule for a solar collector that was proposed earlier by the dispatcher. In the figure, 1 is a cylindrical base, 2 is a transparent dome-shaped head, and these constitutes a capsule 3 for a solar collector, and in use, a solar collector 10 is placed inside the capsule 3 as shown.
is accommodated.

This solar collector has a large number of lenses (e.g. 7, 19 lenses) for concentrating sunlight, a round sunlight direction sensor that detects the direction of the sun, and holds them together. A support frame B, a first rotation shaft 14 for rotating the support frame B, a first motor for rotating the first rotation shaft 14, and a support for supporting the lens U through the motor mechanism. It has an arm 16, a second rotating shaft 17 disposed perpendicular to the first rotating shaft 14, a second motor 18 (see FIG. 2) that rotates the second rotating shaft, and the like. The direction of the sun is detected by the sunlight direction sensor V, and the detection signal controls the motor B and the lens so that the lens always points in the direction of the sun, and the sunlight focused by the lens H is directed to the lens. The light is introduced into a light guide cable (not shown) having a light receiving end disposed at the focal point of the light guide, and is transmitted to any desired location through the light guide cable. Therefore, in the above-mentioned solar power collecting device, in order to protect the solar power collecting device from wind, rain, dust, etc., the solar power collecting device is housed in a longevity capsule as shown in Fig. 1. Lens 1 is worn out, but due to heat etc. during use.
1 is distorted and its focal position shifts, the focal position of the lens H and the light receiving end of the optical conductor cable do not match, and the light focused by the lens H may not be efficiently introduced into the optical conductor cable.

In such a case, in the conventional technology, the entire capsule is removed and the light receiving end of the optical conductor cable is adjusted to match the focal position of the lens, but the work of removing the capsule is troublesome. Furthermore, there is a drawback that dust may adhere to the lens or the sunlight direction sensor during adjustment work.

The present invention was made in order to eliminate the drawbacks of the prior art as described above, and as shown in Fig. 2, a #2D opening/closable entrance/exit is provided in the base portion of the capsule through which a person can enter/exit. It is. In addition, Figure 2 is a view of the solar collector inside the capsule from the back side, and in the figure, parts that have the same function as in Figure 1 are given the same reference numbers as in Figure 1. It is attached. However, in FIG. 2, the second motor for rotating the second rotation axis r shown in FIG.
υ is an adjustment tool for aligning the light-receiving end of the optical conductor cable with the focal position of the lens.Actually, the light-receiving end of the optical conductor cable is fixed at point P of the adjustment tool. By opening the door 20, entering the capsule, and adjusting the adjusting tool 19 in the X and Y directions, the light guide end of the light guide is brought into alignment with the focal position of the beams.

As is clear from the above description, according to the present invention, a system is provided in which the light receiving end of the light conductor cable is adjusted to align with the focal position of the solar light condensing lens by entering the capsule housing the solar light collecting device. Since it is possible to unwind the optical conductor cable, it is possible to significantly improve maintainability after installation compared to the conventional technology.
