The specific embodiment
With reference to Fig. 1, solar column system 20 comprises the high central receiver system 22 of assembling, central receiver system 22 has receiver 24, and the square on the ground predetermined altitude of receiver 24 is couple to tower structure 25 to receive solar radiation S from a plurality of solar tracking mirrors or heliostat 26.The salt of fusing or other heat-transfer fluid are transmitted through central receiver system 22 and are heated from cold tank system 28.Heated heat-transfer fluid is transferred to hot tank system 30 then.When needs power, the heat-transfer fluid of heat is pumped into steam generation systems 32 and produces steam.This steam drives steam turbine plant/generator system 34 and produces electric energy so that be transferred to electrical network.Heat-transfer fluid from steam generator get back to cold tank system 28 with storage up to central receiver system 22, being heated once more, steam is recovered by condenser system 36 simultaneously.Disclose concrete component configuration in the embodiment shown although should understand, adopted any configuration of heliostat all can benefit from the disclosure.
With reference to Fig. 2, heliostat 26 generally comprises base 40, joint 42, frame assembly 44 and heliostat array 46.Base 40 supported joints 42 with allow frame assembly 44 and thereby allow the joint motions (articulation) of heliostat array 46, thereby follow the tracks of the sun and focus on solar radiation S as required.
With reference to Fig. 3 A, base 40 can be and limits longitudinal centre line A and radius r 1(Fig. 3 B) roughly cylinder.In disclosed non-limiting example, hemispherical cap 48 covers base 40.
Joint 42 generally comprises first link, 50 and second link 52.First link 50 comprises first bow-shaped arm 54 with end pivoting 54A, 54B, and second bow-shaped arm 56 with end pivoting 56A, 56B.As shown in the figure, end pivoting 54A, 54B limit initial elevation angle axis B, and end pivoting 56A, 56B qualification initial orientation angle axis C(is also shown in Figure 4).End pivoting 54A, 54B make axis B transverse to axis C with respect to the orientation of end pivoting 56A, 56B.In a non-limiting example, axis B is perpendicular to axis C.
Kinematics combination by uniqueness has realized the smooth and continuous motion of gamut under no singular point condition.This range of movement has been avoided any rare non-sun collection action (maneuver).
With reference to Fig. 7 A, be attached at the orientation and the position of the drive system 70 qualification heliostat arrays 46 between base 40 and the heliostat array 46 at 2 e, f place on the heliostat array 46.Drive system 70 generally comprises and is attached at heliostat array 46(by fixed mount 74A, 74B) with base 40(by skew arm 76A, 76B, Fig. 7 B) between two drive rod 72A, 72B, for example driving screws.
Drive system 70 is regulated heliostat array 46 to provide joint motions so that the range of movement that is provided by joint 42 to be provided with respect to base 40.Joint 42 is essentially heliostat array 46 a some g in the space is provided.By other two some e, f being defined as representative, set up the definition and the direction on heliostat array 46 planes by fixed mount 74A, 74B.By this way, do not have singular point, and do not need heavy significantly alignment orientation angle to continue to follow the tracks of the sun.On the contrary, realize solar tracking in level and smooth and continuous mode.
