SOLAR TRACKING CONCENTRATOR

摘要

The present invention relates to a solar tracking concentrator comprising: an east-west tracking means for tracking the movement of the sun in the east-west direction from the upper part of a base frame; a support disposed vertically on the east-west tracking means; a concentrator-type parabola system disposed so that a shaft thereof is supported by the support, and having a second parabola disposed at a position slightly past the focal point of a first parabola having a wide area so that the high-density light is concentrated in the center of the first parabola; and an altitude tracking means disposed on the support so as to have the concentrator-type parabola system tracking the solar altitude, the present invention further comprising: a prism case disposed so as to be positioned in the rear of the light transport hole in the center of the first parabola of the parabola system, and so as to move angularly by means of the driving power of an altitude tracking motor of the altitude tracking means; and a light guidance means coupling a total-reflection rectangular prism to the prism case. The light guidance means rotates half as much as the rotational angle of the altitude tracking means, thereby allowing the high-density light to be always guided and supplied to the same location.

主权项

1. A solar tracking concentrator 1 comprising:
an east-west tracking means 3 for tracking the movement of the sun in the east-west direction from the upper part of a base frame 2; a support 4 disposed vertically on the east-west tracking means 3; a concentrator-type parabola system 5 disposed so that a shaft thereof is supported by the support 4, and having a second parabola 53 disposed behind the focal point of a first parabola 51 having a wide area so that high-density light is concentrated in the center of the first parabola 51; and an altitude tracking means 6 disposed on the support 4 so as to have the concentrator-type parabola system 5 tracking the solar altitude,the solar tracking concentrator further comprising:
a prism case 82 which is disposed so as to cause a shaft thereof to be supported by the support 4 such that the prism case is positioned in the rear of a light transport hole 51a formed in the center of the first parabola 51 of the concentrator-type parabola system 5, and so as to move angularly by means of the driving power of an altitude tracking motor 61 of the altitude tracking means 6; and a light guidance means 8 composed of a total-reflection rectangular prism 83 coupled to the prism case 82,
wherein the light guidance means 8 rotates half as much as the rotational angle of the altitude tracking means, thereby allowing the high-density light to be always guided and provided to the same location.
