Description

TRUE DESCRIPTION

From the drawing and even better from the photos shown at the bottom of the question it is possible to identify the joints supported by the supports and Ϊ bearings present both on the rotation from east to west (position 2) and on that from north to south (position 1). The stainless steel parabola is mounted on the inner ring. The center is equipped with a screw (position 3) on which discs are mounted to balance the rotation and to adjust the depth from the concentrator (position 4). The reflector (position 5) is in stainless steel with suitable reflection (85%) and is supported by ribs I connected on the inner ring that regulate the convergence angle on the concentrator, The gearmotors for movement are mounted on position 6 and 7 of the rings. The gearmotor in position 7 (as well as the one in position 6) is assembled with 2 coaxial gearboxes (7-a-b), and has a ratio from 1 to 33000 "it is moved (every 5 minutes) by a direct current motor from 30 watts (position 8) powered by a 10 watt photovoltaic panel. The outer ring is in perfect balance with the weight between the gearmotor 7 and the concentrator 4. The concentrator 4 is made up of an outer steel cylinder 500 mm long, while a flint glass cylinder with an index of refraction greater than 1.8.1 rays converging on the concentrator are directed to the bottom and "captured" by a copper plate (diameter of 200 mm), (position 4a) coated with black copper oxide. The prototype test demonstrated low loss both by convection and by electromagnetic radiation. The ratio between the absorbing surface and the absorbing surface is 3 to 500 with an efficiency of 72% to the fluid (also considering the losses due to radiation and convection). In this way the fluid temperature is programmable by computer, choosing the temperature each time according to its speed. From the photos the flanges and joints present on the whole structure can be identified. All the pieces that make up the tracker can be built on numerically controlled machines (half operator for about 100 pieces per day on a single operating machine) while the assembly of the prototype (external diameter 3.75 meters) can be performed in 2 hours by 3 operators.
