The specific embodiment
Fig. 1 represents the schematic plan view of a heliostat, and it has a square reflector part 10 in the bearing that is bearing in rectangular frame 12 forms 11.Bearing 11 is used for surface bearing reflector part (as shown in Figure 4) on ground level 13, and bearing itself is pivotably mounted on the supporting structure 14.The fulcrum 15 of bearing (being called " first axle " later on) is fixing, and parallel with ground level 13.
1. first axle 15 is fixing, and be parallel with ground level 13;
2. second axle 16 is positioned on the line of the point farthest by reflector part 10; With
3. the shape of reflector part 10 can make heliostat placement close to each other, and then the heliostat array can optimally cover ground.
Under the situation of structure shown in Figure 1, second standard can not satisfy, because second axle 16 diagonal by rectangle not.In addition, will mention, use hexagon reflector, can satisfy the 3rd standard best with special geometry of determining in this specification back.
The structure of Fig. 2 and Fig. 3 is more superior than structure shown in Figure 1.Fig. 2 represents to utilize cornerwise second axle 16 by square, the reflector part 10 that is pivotably mounted on the prescription shape on the corresponding bearing 11.Equally, Fig. 3 represents to utilize second axle 16 by hexagonal diagonal angle, is pivotably mounted on one group of hexagon reflector part 10 on the corresponding bearing 11.
Yet in Fig. 2 and structure shown in Figure 3, under the certain inclination of the reflector part in bearing and/or bearing, the radiated solar energy that at least some bearings 11 can block incident is radiated on the reflector.This can reduce the performance of array, and at least some heliostats in the array are separated, thereby has reduced the effective covering to ground.In addition, this bearing itself can not form the optimum covering to ground.
The seat structure that adopts Fig. 4～6 to schematically show can be avoided these problems.
Shown in Fig. 4～6, bearing 11 stretches out backward from reflector part 10, and is shaped as arc, or more particularly is semicircle.The center of radius 17 of bearing is consistent with the geometric center of the reflecting surface of reflector part, and it and first axle 15 are in a straight line.The end portion 18 of bearing is utilized the axle (not shown) that overlaps the bearing supporting of placing with second axle 16, is connected with the reflector part.
Shown in schematic diagram, usually, bearing 11 can make a metal or plastic frame, and is installed on the supporting structure 19, and reflector part 10 is placed on requiring on the height above the ground level 13.
Fig. 5 represents to be arranged in a row, and is installed in a plurality of reflector parts on the bearing, and Fig. 6 is illustrated in a plurality of rows in the little heliostat array.Under each situation, the heliostat in each row is all linked together by a driving shaft 21.In addition, in each row, utilize an axle 23 of doing to move, a plurality of parallel actuator 22 that stretches out backward from corresponding reflector part 10 is linked together.
Fig. 7 and Fig. 8 represent to make the reflector part around second axle 16, the another kind of method of the moving movement of the reflector part 10 of a heliostat that rotates with respect to bearing 11.Because when actuator 22 rotates around fulcrum, when reflector part 10 was rotated, the effective length of actuator 22 (in vertical direction) changed, and therefore must take measures to keep the connection between actuator 22 and the shifting axle 23.As shown in Figure 8, it can be scalable by making actuator, or as shown in Figure 7, by making actuator 22 carried out the driving of rotating around fulcrum, and raising and reducing moving movement axle 23 reaches.
Though, between adjacent heliostat, to shade, the length between the end portion 18 of bearing 11 will adapt with main length of reflector part 10, and preferably the size of bearing 11 is less.This is illustrated among Fig. 9, when size changes, must take some special structures, drives actuator 22.
As mentioned above, the shape of reflector part 10 should be able to make heliostat place optimumly, and is compact.This can reach by making the reflector part with one or another kind of method (in general) shown in Figure 10 A, B and the C.Under each situation, reflector part 10 is the hex shape that comprises four limits 24 of three pairs of parallel limits and equal in length.In addition, under each situation, the length of leading diagonal a is than on the last length of the distance between two relative limits 25 of each part.Hexagonal limit is proportional, and the arc 27 that makes an imaginary circle by four angles of rectangle part is fully in the triangle shaped tip part; Or under maximum conditions, tangent with two of each gable adjacent limits.In this case, hexagonal ratio satisfies following standard
a〉=
c+
b 2/
c(formula 1)
In the formula, in either case,
cLength corresponding to each limit 25.In one group of little at interval reflector, each reflector is all proportional, to satisfy formula (1).Therefore, when driving heliostat, can avoid the reflector collision.As a result, even when reflector was at interval very near, this group reflector also can cover 100% ground.
