System forms.Heliostat cost accounts for more than the 40% of tower-type solar thermal power generating system totle drilling cost, therefore, in order to reduce system
Cost of electricity-generating, promote the commercialization process of tower type solar electricity generation system, it is necessary to improve heliostat field light gathering efficiency, reduce the settled date
Mirror material cost, processing cost, cost of transportation, assembly and adjustment cost, and maintenance cost etc..In order to reach the mesh for reducing cost
, domestic and international heliostat has mainly carried out great dynamicses in terms of the material cost and processing cost of supporting construction and has studied and achieve
Certain achievement, but it is also to be studied in terms of maintenance cost and raising mirror field light gathering efficiency.At present, the settled date being used widely
Mirror is T-shaped heliostat, when heliostat does not need work or in strong wind atmosphere often in protection posture, i.e. heliostat reflecting surface water
Flat upward, such dust is easily deposited in mirror surface, makes reflectivity that influence light gathering efficiency be greatly lowered, or needs to increase
Add speculum cleaning frequency, so as to add heliostat maintenance cost.In addition, mirror-type face is rectangle, arranged in Jing Chang
When, gear light and shade occurs for the opening position that adjacent front and rear row heliostat is easy at four angles of rectangle, so as to reduce Jing Chang
Light gathering efficiency.
Utility model content
The purpose of this utility model is the defects of overcoming above-mentioned prior art, there is provided a kind of subcircular can back-off single column
The heliostat device of support, so as to reduce the maintenance cost of heliostat, improve heliostat field light gathering efficiency.
To reach above-mentioned purpose, the utility model takes following technical scheme：
The utility model heliostat is made up of speculum, mirror support, column and transmission device.Mirror unit is fixed
On mirror support, transmission device is arranged on column, and the both sides of transmission device and the crossbeam of mirror support are connected.
Described speculum integral face type is spliced by multiple mirror units, and speculum overall profile is shaped as circle
Or subcircular, the face type of mirror unit can be curved surface or plane.Transmission device bottom end face is arranged on the top of column, transmission
Connected in the middle part of the end face of device both sides and the crossbeam of mirror support.Under the driving force effect of transmission device, speculum branch
Frame and full reflection mirror unit can surround the elevation angle output axis rotation at least 180 degree of transmission device.Mirror support and anti-
Penetrate mirror to be arranged symmetrically relative to column, and speculum is provided with opening in opening position corresponding with column, makes speculum and reflection
Mirror support can rotate to back-off posture, i.e. the reflecting surface side of speculum is towards ground.
The utility model has following features：First, heliostat mirrors integral face type is using circular or subcircular arrangement
Mode, can effectively solve Jing Chang and be in the light or shadow problem, improve mirror field efficiency.Second, heliostat reflects in off working state
Mirror is parked in back-off posture, reduces the accumulation of dust on the reflecting surface, reduces cleaning frequency, so as to reduce heliostat safeguard into
This.

Embodiment
The utility model is described further with reference to the accompanying drawings and detailed description.
Embodiment one
The utility model embodiment is single upright supports formula subcircular heliostat.
Overall structure of the present utility model is as depicted in figs. 1 and 2.Fig. 1 is the front view of the heliostat structural representation, is schemed
2 be the rearview of the structure.The heliostat structure includes speculum 1, column 2, transmission device 3 and mirror support 5.Speculum
1 is spliced by some mirror units 11 by linear array or circumference array mode, the contour shape for the speculum 1 being combined into
For circular or subcircular, i.e., do not arrange mirror unit at the corner of speculum 1.When heliostat as some rows forms the settled date
During mirror field, can be reduced between adjacent front two rows heliostat sunshine block with shade phenomenon, subtract heliostat line space
It is small, Jing Chang light gathering efficiency is improved, and reduce mirror field floor space.The face type of mirror unit 11 can be plane, can also
It is curved surface.Mirror unit 11 is fixed on mirror support 5, the both ends of the surface and biography that mirror support 5 passes through the middle part of crossbeam 51
Dynamic device 3 connects.The output shaft of transmission device 3 and the centre of gyration of crossbeam 51 overlap, and form elevation angle rotation axis 55.It is all
Mirror unit 11 and mirror support 5 form an entirety, under the driving force effect of transmission device 3, can be revolved around elevation angle
Shaft axis 55 rotate, and realize that height angular direction tracks to day.The utility model heliostat elevation angle rotational angle is more than 180 degree,
