A ROTATABLE ABSORBER SUPPORTED ON A COLUMN ALONG A CONCAVE SPHERICAL SUNLIGHT REFLECTOR™S VERTICAL AXIS�.

摘要

The device named as A rotatable absorber supported on a column along a concave spherical sunlight reflector™s vertical axis� is a rotatable solar energy absorber mounted on a column along vertical axis of a concave spherical sunlight reflector such that vertical axis of said absorber coincides with vertical axis of said concave spherical sunlight reflector. Before beginning of discussion about construction details of the device we assume that there is a stationary concave spherical sunlight reflector� suitable for holding and supporting a column along its vertical axis and also suitable for supporting a solar energy absorber™s holding long arms on its top aperture. The said device comprises of following components. 1) A ˜vertical pipe™ or ˜column™ is provided such that its vertical axis coincides with vertical axis of said concave spherical sunlight reflector. Said column is either a thick circular pipe made of metal or a column or a pedestal made of metal or any other suitable material. A ˜thrust bearing™ is provided at top end of said ˜column™ to support and to allow rotation of objects to be supported over it. 2) A means for solar energy absorption comprising of a ˜either a semi-circular or polygon outlined solar energy absorber or plurality of solar energy absorbers interconnected by inlets and outlets™ is ˜held, and supported™ in a suitable shaped framed structure which is either provided with thermal insulation or without thermal insulation�. ˜Framed structure of said means for solar energy absorption� is fitted either with a short length circular pipe, or with any other suitable holding means at its bottom end� along its vertical axis to support said means for solar energy absorption� in rotatable manner on said ˜column™ provided along vertical axis of said concave spherical sunlight reflector. 3) Detachable holding means� like one or two long parallel pipes (or rods) or ˜any other suitable rotatable holding means™ are connected to top side end of framed structure of said means for solar energy absorption� to serve the purpose of holding said framed structure or body said means for solar energy absorption such that ˜centroid and middle vertical plane™ of said framed structure or body said means for solar energy absorption� always coincides with vertical axis of said concave spherical sunlight reflector. Said detachable holding means connected to top side end of framed structure of said means for solar energy absorption� are supported on top end of the concave spherical sunlight reflector such that said detachable holding means� longitudinal axes are at right angle to vertical axis of said concave spherical sunlight reflector. Said ˜solar energy absorber™ can be oriented either continuously or at regular time intervals at focus of sunlight reflected in concentrated manner by said ˜concave spherical sunlight reflector™, such that said ˜solar energy absorber™ is capable of collecting most of energy of sunlight reflected by said ˜concave spherical sunlight reflector™.
