Combined pressurized air solar heat sensing head assembly and a pressurized water drive system used to move solar energy collectors in tracking the sun

摘要

In moving solar energy collectors to track the sun, there are combined:PPa pressurized air solar heat sensing head assembly, utilizing compressed air in adjacent and opposing chambers, each chamber having a flexible diaphragm closely contacting an actuator of a four way valve of a pressurized water drive system, with these chambers being located on opposite sides of a sunshade assembly;P Pa pressurized water drive system having the four way valve moved by the pressurized solar heat sensing head assembly, whereby water under pressure from this valve is directed to one side or the other of an actuator utilizing compact and collapsible hoses, which in expanding to receive the pressurized volume of water, move a power take off connector, in turn attached to a cable of a pulley drive subassembly, in turn rotatably secured to solar energy collectors to adjustably position them; andPPsolar energy collectors selected from many types each of which is mountable about one structurally supported axis assembly, to make automatic daily adjustments, and about another structurally supported axis assembly, to make seasonal adjustments of these solar energy collectors in tracking the sun to gain the benefits of maximum solar energy.
