Description

[Detailed explanation of the idea]

0001

[Industrial application field]

The present invention relates to a device for introducing sunlight into a building using a reflecting mirror.

0002

[Conventional technology]

Conventionally, this type of device combines multiple reflecting mirrors and directs sunlight across the reflecting mirrors. A device configured to reflect the light and introduce it into a building has been proposed.

0003

[Problem that the idea aims to solve]

However, the conventional device has a complicated structure, is bulky, occupies a large space, and is difficult to handle. There is a problem when attaching.

0004

[Means to solve the problem]

This invention is a system for introducing solar light into buildings to solve these problems. In connection with the installation, a support frame rotatably supported on the pedestal frame around a first rotation axis, and a a single counter rotatably supported around a second rotation axis perpendicular to the first rotation axis; A projecting mirror, a rotation drive device for the support frame and the reflecting mirror, and a sun position are detected for each of the times. A solar position detection sensor that controls the rotation drive device and has the ability to distinguish between clear skies, cloudy skies, and nighttime. This structure solves the above problems.

[0005]

[Effect]

Since the present invention is configured as described above, the sun position detection sensor is used when identifying clear skies. The sensor is activated, and the rotation of each rotation drive device of the support frame and the reflector is activated by the signal. The support frame is rotated by a predetermined angle around the first rotation axis with respect to the mount by controlling the rotation drive. and the reflecting mirror is perpendicular to the first rotation axis relative to the support frame. By rotating the mirror by a predetermined angle around the second rotation axis, the reflector is placed in a predetermined position. This is to introduce reflected sunlight to a predetermined location.

[0006] If the weather continues to be clear, the reflector will be activated by the sun position detection sensor from time to time. It is rotated to follow changes in the position of the sun to be detected. In addition, on cloudy days or at night, the solar position detection sensor is not activated and the reflector is The surface is rotated by the first or second rotation axis to a position perpendicular to the zenith direction. This is to prevent sky light from being blocked as much as possible.

【Example】

The present invention will be described below with reference to the illustrated embodiments. Reference numeral 1 denotes a support frame rotatably supported on a pedestal 2 around a first rotation axis X-X'; 3 is a second rotation axis Y-Y' that is orthogonal to the first rotation axis X-X' axis on the support frame 1. A reflector that is rotatably supported around the 4 is a rotational drive device for the support frame 1; Reference numeral 5 denotes a rotational drive device for the reflecting mirror 3, which is attached to the support frame 1 and controls the sun position. Upon receiving a signal from the control unit 7 connected to the detection sensor 6 by a signal cable, The rotational drive of each rotational drive device 4, 5 is controlled.

[0008] In the figure, reference numeral 8 denotes each of the rotary drive devices 4, 5, the sensor 6, the control section 7, and the power supply cable. This is the power supply section connected by a cable. In addition, 9 in the figure is a dome that covers the entire device. It is. Since the illustrated embodiment is constructed as described above, as shown in FIGS. 2 and 3, A base 2 is installed on the roof of the building so as to straddle the reflected light and sky light introduction holes b. The sensor 6 is installed via a foundation c, and the sensor 6 is kept in operation at all times.

[0009] When clear weather is identified, the sun position detection signal from the sun position detection sensor 6 is transmitted to the control unit 7. A control signal is sent to each of the rotary drive devices 4 and 5, and a control signal is sent to each of the rotation drive devices 4 and 5. The rotation angle of the support frame 1 with respect to the pedestal 2 around the X-X' axis, and the rotation angle with respect to the support frame 1. By controlling the rotation angle of the reflecting mirror 3 around the Y-Y' axis, the reflecting mirror 3 can be placed in a predetermined position. It is installed at a certain location and introduces reflected sunlight to a predetermined location within the building.

0010 In addition, if the weather continues to be clear, the reflector 3 will reflect the position of the sun as detected by the sensor 6 from time to time. rotates to follow the fluctuations of. In addition, on cloudy days or at night, the surface of the reflector 3 should not be activated without activating the sensor. To the position perpendicular to the zenith direction with respect to the rotation axis X-X' or Y-Y' It is rotated and held to prevent sky light from being blocked as much as possible.

[0011] Note that the position of the reflecting mirror 3 in FIG. 2 is for cloudy weather or night time. FIG. 4 shows an example in which the device A of the above embodiment is installed in a building B, with an atrium d and an indoor e. This shows the case where it is installed on the roof that communicates with the roof. Figure 3 shows the need to reduce the cooling load when introducing solar reflected light into a building. A case is shown in which a heat ray reflective glass 10 is incorporated at the top of the reflected light and sky light introduction hole b. There is.

0012 In the figure, parts equivalent to those in the embodiment described above are given the same reference numerals. In this way, the device of the above embodiment does not require combining a plurality of reflecting mirrors as in the conventional method. In this case, a single reflecting mirror 3 is used and it is connected to two axes that are perpendicular to each other, the X-X' axis, and the Y-Y axis. ’By axially driven rotation, sunlight is transferred to the building in response to changes in the sun’s position. The structure is compact and does not require a large space for installation. In addition, it is possible to prevent sky light from being blocked as much as possible at night or on cloudy days. .

[0013]

[Effect of the idea]

In this way, according to the present invention, a single reflecting mirror can be used to quickly respond to changes in the sun's position. It is possible to introduce sunlight into the building by using It does not take up a lot of space for installation, and it can be installed in the sky at night or on cloudy days. This can prevent light from being blocked as much as possible.
