Embodiment 2

[0040] The design of the above-mentioned heliostat concentrating system belongs to the sun tracking and concentrating technology, and has the versatility of sun tracking and concentrating. Therefore, its use can be further developed. For the above-mentioned heliostats, without any change in the main frame pattern, it is only necessary to change the original adjustable parts into fixed structures. And, the toothed part on the drive half wheel is lengthened. If you need to increase the light-gathering multiple, you can divide the reflector of the lighting unit into more reflective sub-mirrors horizontally, and then install all the reflective sub-mirrors in the lighting unit according to the horizontal fixed condensing installation, so that the light spots of the sub-mirror can be gathered into a square; vertically Arranged in a converging manner so that the beam spots of each sub-mirror overlap. Form a fixed multi-mirror condensing and converging lighting unit. In this way, t...

Abstract

The invention relates to a bull wheel-driving and condensation continuously adjustable heliostat belonging to the field of solar energy utilizing and tracing technology. The heliostat has the following basic structure: a T-shaped shaft is set as a horizontal rotating shaft on an upright post support; both ends of the horizontal shaft of the T-shaped shaft are in vertical rotating connection with a upright beam support of a lighting device; a horizontal driving semi wheel with the super large diameter is arranged on the horizontal shaft of the T-shaped shaft; a vertical driving semi wheel with the super large diameter is arranged on a lighting device support; and the lighting device can make horizontal azimuth rotation and vertical altitude angle rotation under the control of a horizontal driving device and a vertical driving device. Nine horizontal lighting units are distributed in the longitudinal direction of the lighting device, and each lighting unit has independent transverse condensation curvature adjusting mechanism and longitudinal light spot converging adjusting mechanism, and double condensation regulation forms that the adjustable range of the condensation multiple of the lighting device is from 1x to 69x.

Description

1. Technical field [0001] The invention relates to solar energy utilization tracking and concentrating technology, which is one of the key technologies of solar energy utilization. 2. Background technology [0002] At present, heliostats generally use a vertical shaft superimposed on a horizontal shaft, and the double shafts are driven to form a T-shaped heliostat transmission system. Such as California, Spain, PSA experimental base, etc., the appearance of the structure is as follows: Figure 24 shown. The structure of this heliostat seems simple, but there are problems in its transmission system. As we all know, the heliostat is a long-distance rotating tracking, due to the huge fan-shaped magnification with the projection distance as the radius. As a result, the angular displacement tracking control scale of the transmission system is compressed to a very small working range; while the transmission error of the system is magnified to thousands of times. Since the sun r...
