Detailed description of the invention
Below with reference to the accompanying drawing of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete description And discussion, it is clear that a part of example of the only present invention as described herein, is not whole examples, based on the present invention In embodiment, the every other enforcement that those of ordinary skill in the art are obtained on the premise of not making creative work Example, broadly falls into protection scope of the present invention.
A kind of heliostat as shown in Figure 1, props up support component 2 and mirror holder 3 including reflecting surface, reflecting surface, wherein, described instead Support component 2 is propped up between described reflecting surface and mirror holder 3 in the face of penetrating, and fixing is connected for realize between reflecting surface with mirror holder 3.Tool Body ground, in the present embodiment, described mirror holder 3 includes auxiliary girder 31, strutbeam 32, bracer 33 and girder 34.It should be noted that this The described mirror holder 3 provided in embodiment is only the goal of the invention that the present invention is clearly described, the present invention is to the concrete structure of mirror holder 3 not Limit.
Below the reflecting surface in the present invention is propped up support component 2 to be described in detail:
Support component 2 is propped up as Fig. 2 and Fig. 4 discloses a kind of reflecting surface for heliostat, including tab and bonding sheet 23, Wherein:
Described tab include the fixed part 21 that be connected fixing with heliostat mirror holder 3 and from described fixed part 21 stretch out curved Folding part 22;In the present embodiment, the fixed part 21 of described tab is fixing even with the auxiliary girder 31 in described mirror holder 3 by rivet Connect, certainly, the fixed part 21 of described tab can also by being spirally connected, the mode such as welding is fixing with mirror holder 3 is connected.
Described bonding sheet 23 is fixedly installed on the kink 22 of described tab, and with the reflection of described heliostat Face is fixing to be connected;Further, at least provided with two bonding sheets 23 on the kink 22 of each described tab.In the present embodiment, The side of described bonding sheet 23 is fixing by the way of gluing with described reflecting surface to be connected, certainly, it is possible to suitable by other Fixed form is fixing with described reflecting surface to be connected, and the present invention is not specifically limited;Additionally, the opposite side of described bonding sheet 23 and institute State the kink 22 of tab use be spirally connected, rivet, weld in any one fixed form fixing connect.
Prop up support component 2 by arranging reflecting surface between reflecting surface and mirror holder 3, can effectively eliminate mirror holder stress to reflection The impact in face, simultaneously, moreover it is possible to the external force that effectively buffering reflecting surface is subject to;It addition, the present invention is by arranging on each tab At least two bonding sheet 23, can make multiple strong points at reflecting surface back form as one, and improves reflecting surface and props up support component 2 Topple rigidity, thus avoid when reflecting surface is in non-standard state, reflecting surface prop up support component 2 because of rigidity of toppling relatively low, make anti- The default face shape penetrating face is destroyed, and affects the quality of flare.
In another embodiment, the fixed part 21 of described tab is arranged in a mutually vertical manner with kink 22.Described fixed part 21 are arranged in a mutually vertical manner with kink 22 employing, it is simple to the installation of described bonding sheet 23, meanwhile, also help the described bonding of reduction Sheet 23 and tab put on the stress on described tab when mounted.
In another embodiment, described tab is elastic component.Described tab uses elastic component, by increasing capacitance it is possible to increase adjust The deformability of full wafer such that it is able to preferably eliminate the stress that reflecting surface is applied by described mirror holder 3, meanwhile, also can be more preferable Other external force that buffering reflecting surface is subject to.
In a preferred embodiment, as it is shown on figure 3, described tab is provided with to kink 22 direction from fixed part 21 Reinforcement 24.By arranging reinforcement 24, the integral rigidity of described tab can be effectively improved, and be not provided with reinforcement 24 Tab is compared, and on the premise of possessing identical enabling capabilities, the tab arranging reinforcement 24 can be made thinner, effectively Save raw material.
In another embodiment, the one during the cross section of described tab is L-shaped, Z-shaped or T-shaped.In the present embodiment, institute The cross section stating tab uses L-shaped design.
In another embodiment, the thickness of described tab is 0.5~3mm.When the thickness of described tab is less than 0.5mm Time, tab is due to the thinnest, it is impossible to reflecting surface plays good supporting role;When the thickness of described tab is more than 3mm, Tab is excessive due to thickness, when reflecting surface is by external force, it is impossible to play good cushioning effect, easily makes reflecting surface rupture.
As it is shown in figure 1, present invention also offers a kind of heliostat, including:
Reflecting surface;
Heliostat mirror holder 3, is used for supporting described reflecting surface;
Reflecting surface props up support component 2, is fixedly installed between described reflecting surface and heliostat mirror holder 3, and described reflecting surface supports Assembly 2 is that the reflecting surface described in aforementioned any embodiment props up support component 2.
In another embodiment of the heliostat of present invention offer, described reflecting surface is spliced by least two reflector element 1 Combine.Use this kind design, can reduce reflecting surface because of area excessive, during transportation, installation and use occur The risk ruptured, it addition, heliostat, needs possess certain curvature or angle in actual use, uses reflecting surface Multiple reflector elements 1 splice and combine formation, can be so that curvature and angle to reflecting surface are adjusted.
In another embodiment of the heliostat of present invention offer, as it is shown in figure 1, on a described tab at least On the bearing of trend of two described bonding sheet 23 lines, two described reflector elements 1 adjacent in described reflecting surface are by described Reflecting surface props up support component 2 and connects.After reflecting surface regulation to predetermined angle, prop up support component 2 by adjacent two by reflecting surface Reflector element 1 couples together, and the most separate reflector element can be made to form a complete entirety, when certain reflection is single Unit 1 by External Force Acting time, suffered power can be dispersed to adjacent reflector element 1, reduce single reflector element 1 and occur The risk damaged, it addition, couple together adjacent reflector element 1, it is also possible to improves the wind loading rating of reflecting surface, improves whole The stability of reflecting surface face shape, thus ensure the stability of flare.
The above, the only present invention preferably detailed description of the invention, but protection scope of the present invention is not limited thereto, Any those familiar with the art in the technical scope that the invention discloses, the change that can readily occur in or replacement, All should contain within protection scope of the present invention.Therefore, protection scope of the present invention should be with scope of the claims It is as the criterion.
