Description
Technical field
The invention belongs to tower type solar energy thermal power generation technical field more particularly to a kind of heliostat mirror holders.
Background technique
Tower type solar energy thermal power generation is that sunlight is gathered one using a large amount of directional mirror (heliostat) to be mounted in
On the central heat exchanger (recipient) of tower top.Orientation due to the sun within one day is ceaselessly changing, then corresponding,
Heliostat should also follow the variation of solar azimuth and changing location and reflection angle, can just make reflection light directive tower always in this way
The central heat exchanger on top is without the offset of light, and here it is the solar tracking campaigns of heliostat.In solar tracking motion process, instead
It penetrates mirror to need to be firmly fixed on sun-following device, and is accurately moved with the rotation of sun-following device shaft.Reflecting mirror simultaneously
Face type be related to the shape of reflected light hot spot.The face type of reflecting mirror is better, and the hot spot being radiated on central heat exchanger is got over
Rule, more accurate to the control of reflection light, light spot energy is more concentrated, and light spot energy is made to be evenly distributed on central heat exchanger table
Face.Conversely, the face type of reflecting mirror is irregular, then the hot spot being radiated on central heat exchanger can be deformed, be dissipated, not only difficult
To control the motion profile of reflection light, spot energy distribution also can be uneven.
For the reflecting mirror of heliostat, applying working condition is field, and the factors such as climate, dust storm influence, and environment is disliked very much
It is bad, and long-term motion is kept, control accuracy requirement is very high.Then to the rigidity of support frame, the requirements such as weight want high, to reflection
The face type of mirror is more regular, and face type curvature control is more accurate, and light spot shape is more regular, this is just to the mirror support of heliostat
The design inventive problem of frame proposes very high requirement.
Currently, had considerable in tower type solar power field according to different heliostat structures and reflecting mirror size
Mirror frame structure form.Patent 201220073817.8 as China Intellectual Property Office authorizes discloses a kind of reflecting mirror mirror holder.It should
Mirror frame structure is a circular pipe, and the structure of several supporting beams is arranged on it, since the face type of the mirror holder is to rely on
The material precision of supporting beam is guaranteed, and can not be adjusted, therefore has relatively high requirement to the machining accuracy of part, and
And the integral face type curvature after frame assemblies is unable to get accurate control.
Patent Office of the People's Republic of China announce application No. is a kind of 200710179308.7, entitled heliostat support device, it is wrapped
Column, support device main body and reflecting surface unit support carrier are included, support device main body includes fixing piece, braced frame and transmission
System gusset piece is coupled between support device main body and column by the transmission system of heliostat, and reflecting surface unit supports carrier logical
It crosses single-point support form to be mounted on the fixing piece of support device main body, the central axis of each fixing piece and the corresponding surface of emission
The normal for the reflecting surface unit center that unit supports carrier is supported is overlapped, and makes to have more when installing reflecting surface support carrier
Accurate reference for installation or reference position, support the stickup curved surface of carrier consistent with reflecting surface face type, and by machine-tooled method shape
At the surface precision of curved surface can be improved.But the support device main body of the patent is truss structure, structure is complicated, and steel using amount is big
Higher cost, and type adjustment activity time in face is longer.
It is applied from the point of view of the support frame of the reflecting mirror of solar energy thermal-power-generating from currently existing, some volumes are bigger than normal, and structure is multiple
Miscellaneous, some spectacle frame machining process require height, and processing and manufacturing difficulty is high, are difficult to run under actual condition.It is existing it is tower too
Positive energy heat generating system suffers from the drawback that
First, mirror surface type is difficult to adjust；
Second, reflector support preponderance, structure is complicated, at high cost.
