Benefits of technology

[0013]When compared to heliostats of the prior art, the present invention has various benefits. The present invention is lightweight. This feature may be made inexpensively. This present invention may be installed easily. The present invention may be installed in a location where space is not available for a multitude of rigid supports. The present invention may be installed above a location that may be used for a purpose other than support of the invention.

Problems solved by technology

These devices include a high number of parts and a high complexity of parts.
Such a requirement increases operating cost of the device and the likelihood of focusing errors.
The half-angle gearing mirror adjustment means of devices of the prior art are not readily adapted to being ganged.
The parallelogram type mirror adjustment means of devices of the prior art are not readily adapted to being ganged.

embodiment ‘ 2

[0049]Embodiment ‘2’ of the invention is similar to embodiment ‘1’. Embodiment ‘2’ differs from embodiment ‘1’ in the following ways: embodiment ‘2’ includes a different cabling arrangement than embodiment ‘1’ for linking primary and intermediate sun aiming parts, embodiment ‘2’ includes cable equalizing parts 2113, 2123, 2133, embodiment ‘2’ includes a cable tensioning spring 2803, and embodiment ‘2’ includes receiver stay cables 2804 and 2805. FIG. 4 provides an overview of embodiment ‘2’ and FIG. 5 provides various views of cable equalizing part 2113.

[0050]A single sun aiming cable 2114 is fixed at one end to primary sun aiming part 2110, looped around cable equalizing part 2113, and fixed at its other end to primary sun aiming part 2110. A single sun aiming cable 2115 is fixed at one end to secondary sun aiming part 2201, looped around cable equalizing part 2113, and fixed at its other end to secondary sun aiming part 2201. The cables 2114 and 2115 bear on, but are free to slip ...

Abstract

A cable ganged heliostat used to focus radiation from a moving source onto a receiver is disclosed. The primary application of such an invention relates to reflecting the radiation from the sun onto a stationary target. The device orients a reflective surface to a position necessary for imaging using a mirror adjustment means. The device may be used singly or in a ganged array. The mirror and mirror adjustment means of the device may be supported by cables.

Description

BACKGROUND OF THE INVENTION[0001]The present invention relates to a cable ganged heliostat used to focus radiation from a moving source onto a receiver.[0002]The primary application of such an invention relates to reflecting the radiation from the sun onto a stationary target. In such an application, wherein the device is used to orient a reflective surface to reflect light onto a target, the device may be termed a “heliostat”. In another sunlight reflecting application, wherein the device is implemented in an array, wherein a plurality of reflective surfaces reflect light onto a target, the device may be termed a “ganged heliostat”. Light concentration achieved by heliostats or ganged heliostats has several uses which include thermal energy conversion, photovoltaic energy conversion, and daylighting.[0003]In other applications, the device may be used to reflect any other type of electromagnetic radiation such as radio signals, sound waves, moonlight, etc.PRIOR ART[0004]A prior art ...
