Automatic hydraulic motion system of elements of a compact solar collector

An automatic motion system by dilation of a primary heat carrier fluid for acting on elements of a compact solar collector with an integrated storage tank for a fluid to be heated:

• said compact solar collector with the integrated storage tank comprising a plurality of primary conduits for containing the primary heat carrier fluid adapted to the storage of thermal energy, and an external collector element arranged movably with respect to each primary conduit;
• each external collector element is a vacuum tube within which is arranged a respective primary conduit in which the fluid to be heated flows, and each external collector element is configured to rotate on itself, with respect to the respective primary conduit and to at least partially overlap each primary conduit during its motion;
• each external collector element has at least a first collecting face configured to collect solar radiation, and at least a second shielding face suitably made opaque to solar radiation;
• the automatic motion system includes automatic drive and transmission mechanisms comprising at least one hydraulic cylinder with a piston on which is at least one return spring configured to act on the piston, a hydraulic cylinder pressure intake, at least one toothed rack, and toothed gears carried by the external collector elements, whereby said automatic drive and transmission mechanisms are configured to move said external collector elements from the first face of a collecting position automatically as a function of a pressure of the primary heat carrier fluid increasing beyond a set technical volume to actuate, via the primary heat carrier fluid pressure to the intake, the piston in the hydraulic cylinder to move the rack to engage the gears to the second face of a shielding position, and the spring acts on the piston to move the rack to engage the gears to return the external collector elements to the first face of the collecting position as a function of the pressure of the primary heat carrier fluid decreasing below a set technical volume,
• whereby the compact solar collector is automatically protected from damage by excessive solar radiation using dynamic shielding, and the motion system automatically operates by an intrinsic ability to self-regulate with no external control and no external power source other than solar energy.
