Clear, complete description, it is clear that described embodiment is only the utility model part of the embodiment, rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment obtained, belong to the scope of the utility model protection.
Fig. 1 is to be preferable to carry out the structural representation of heliostat that exemplifies according to one.As shown in figure 1, heliostat includes four
Individual shape is first point of eyeglass, 1, second point of eyeglass 2, the 3rd point of eyeglass 3 and the four split mirror piece 4 of right-angled trapezium.First point of mirror
1, second point of eyeglass 2 of piece, the 3rd point of eyeglass 3 and four split mirror piece 4 arrange in the direction of the clock around first nodal point, four points
The right angle circumference array that the right angle waist of eyeglass and bottom are formed is in first nodal point periphery and four points of eyeglasses is spliced to form just
Hexagon.Wherein, the heliostat in the application is the regular hexagon that the size length of side is 2.5~2.8 meters.
In the present embodiment, the right angle that the right angle waist of four points of eyeglasses and bottom are formed can together with direct splicing, i.e., four
The right-angled apices that the individual right angle waist for dividing eyeglass and bottom are formed overlap with first nodal point, namely between adjacent point of eyeglass between
Away from for 0mm.In the heliostat of the present embodiment, because heliostat only includes four pieces of points of eyeglasses, and four pieces of points of eyeglasses are by clockwise
Direction arranges in circumferencial direction, when dividing eyeglass to expand, can be expanded to the peripheral direction of circumference, therefore divide mirror in the present embodiment
The arrangement of piece, eyeglass will not be caused because expansion and the problem of rupture.In order that it is swollen to divide eyeglass to have in each direction
Swollen threshold degree, it is preferable that the spacing d between adjacent point of eyeglass is 0~50mm.
Regular hexagon heliostat in the application, its size length of side are 2.5~2.8 meters.
As the presently preferred embodiments, first point of eyeglass, 1, second point of eyeglass 2, the 3rd point of eyeglass 3 and four split mirror piece 4 are using plating
Silver-colored float glass process plane silver mirror.
As one of which preferred embodiment, first point of eyeglass, 1, second point of eyeglass 2, the 3rd point of eyeglass in the application
3 and four split mirror piece 4 fixed by the first back bracket.Fig. 4 is according to first back bracket for being preferable to carry out exemplifying
Structural representation.As shown in figure 4, the first back bracket includes transverse triangle beam 401, longitudinal triangular beam 402 and support 403.
As another preferred embodiment, first point of eyeglass, 1, second point of eyeglass 2, the 3rd point of eyeglass 3 in the application
It can also be fixed with four split mirror piece 4 by the second back bracket.Fig. 5 is to be preferable to carry out the second back bracket for exemplifying according to one
Structural representation.As shown in figure 5, the second back bracket is radial supporting structure.
As yet another preferred form, first point of eyeglass, 1, second point of eyeglass 2, the 3rd point of eyeglass 3 in the application
It can also be fixed with four split mirror piece 4 by the 3rd back bracket.Fig. 6 is to be preferable to carry out the 3rd back bracket that exemplifies according to one
Structural representation.As shown in fig. 6, the 3rd back bracket includes L-type connection sheet 601 or U-shaped connection sheet.First point of eyeglass 1,
Two points of eyeglasses 2, the 3rd point of eyeglass 3 and four split mirror piece 4 are Nian Jie with the 3rd back bracket by two-component AB glue.
The one of which preferred fabrication method of the application regular hexagon heliostat is described in detail below.
Using 2 pieces of 3660x2440mm silver mirrors, every piece of minute surface by certain angle cut into 2 it is trapezoidal, such as A, B in Fig. 2
Two pieces of points of eyeglasses, two pieces of silver mirrors obtain four pieces of points of eyeglasses.The splicing schematic diagram of 4 pieces of trapezoidal point of eyeglasses as shown in Figure 3 is spliced into
Regular hexagon eyeglass, in the first back bracket (or the second back bracket or the 3rd back bracket) of heliostat.Pass through
The regular hexagon heliostat that this kind of method obtains, its specular cross section are 17.8m2。
Size for 3.66x2.44 rice silver mirror lens producing technology it is relatively simple, but its exist area it is larger and crisp lack
Point, the cutting method being divided into two by above-mentioned inclined cutout can effectively overcome this shortcoming.Regular hexagon in the application
Heliostat, only four pieces of eyeglasses, simple in construction, installation accuracy is easily guaranteed that, has very high practical value.Simultaneously as just
The heliostat of hexagon is more nearly circle, therefore the optics of the regular hexagon heliostat in the application than quadrangle and pentagon
Efficiency significantly improves, and has more excellent spotlight effect.
It is further preferred that spliced eyeglass can also be pressed into certain sphere by mould in the embodiment of the present application
Or paraboloid of revolution type, and then the hot spot after solar light focusing is more nearly circle, spotlight effect is more excellent.
From above technical scheme, compared to the heliostat used in existing tower type solar electricity generation system, the application
In heliostat not only larger specular cross section, but also good with simple in construction, convenient maintenance and replacement, spotlight effect
Advantage.
It should be appreciated that the accurate knot that the utility model is not limited to be described above and is shown in the drawings
Structure, and various modifications and changes can be being carried out without departing from the scope.The scope of the utility model only will by appended right
Ask to limit.
