Embodiment 1
[0054] figure 1 A partially enlarged view showing a heliostat 1A as a first embodiment of the present invention, figure 2 A perspective view showing a heliostat 1A composed of nine facet mirrors 20 . Each of the facet mirrors 20 is fixed to the tilt mechanism 10A by means of the facet mirror holder 19 , and the tilt mechanism 10A is provided on the stand 16A. In addition, the tilt mechanism 16A is connected in the X-axis direction by the X-axis link 11A via the X-axis arm portion 13, and is connected in the Y-axis direction by the Y-axis link 12A via the universal joint 15 and the cylinder mechanism 14A. Get up and move in tandem with each other. Here, the facet mirror 20 is adjusted in advance using the facet mirror holder 19 at an attachment angle so as to have a focal point at an arbitrary point.
[0055] figure 2 It is an example showing the case of combining a plurality of facet mirrors 20 as the heliostat 1A. Here, nine facet mirrors 20 are connected by links in t...
Embodiment 2
[0059] image 3 is a schematic front view showing a heliostat 1B as a second embodiment of the present invention, Figure 4 Represents a side profile view. The heliostat 1B is configured such that a facet mirror 20 having a deflection mechanism 10B below is centered on a Y-axis link 12B. image 3 Rotate in the left-right direction shown. A plurality of skew mechanisms 10B are connected together by an X-axis link 11B as a link mechanism, and the connection is located at image 3 A plurality of facet mirrors 20 in the left-right direction (X-axis direction) undulate in linkage.
[0060] In addition, if Figure 4 shown, with image 3 The X-axis direction is perpendicular to the Y-axis direction (relative to image 3 The inner near-front direction of the paper or Figure 4 The ups and downs in the left and right directions) can be realized by linking the plurality of facet mirrors 20 to the Y-axis link 12B, respectively.
[0061] According to this embodiment, since the lin...
Embodiment 3
[0063] Figure 5 Showing the outline of a heliostat 3A as a third embodiment of the present invention, Figure 6 Represents what it looks like when the sun is being tracked. The heliostat 3A is provided with a plurality of facet mirrors 20 having a columnar support member 36 below, and the plurality of facet mirrors 20 are arranged to have a focal point. The head of the joint is rotatably supported by an intermediate fixing plate 32 via a rotation mechanism 31 . The rotation mechanism 31 of the head can also be realized by a joint with two degrees of freedom other than the above-mentioned spherical joint.
[0064] The upper part of the support member 36 is connected with the facet mirror 20 via the installation angle adjustment mechanism 30. When installing the heliostat, the installation angle of the facet mirror 20 is adjusted by the installation angle adjustment mechanism 30, so that the reflection of the plurality of facet mirrors 20 Light has a focal point at an arbitr...
