Description
Technical field
The present invention relates to a kind of plane mirror devices of directed projection sunshine, promptly be commonly referred to the device of heliostat, belong to application of solar.
Background technology
Heliostat device as its name suggests, its effect is that sunshine is accurately positioned on certain target, is commonly used to the optically focused parts as solar energy light collecting lighting device or heat generating system.
Along with the continuous development of solar utilization technique,, wish during design that heliostat device has enough tracking accuracies in order to obtain desirable daylighting effect.Yet, to understand according to the applicant, the tracking of existing heliostat device all has approximation, can't satisfy the instructions for use of scientific and technological progress to the tracking accuracy increasingly stringent.
Finding the geneogenous systematic error of design ubiquity of existing heliostat device through intensive research back.Concrete condition is as follows:
In general, when using, need place by heliostat the device of solar receiver and so at the target place that sets, because its tracking accuracy is to the receiver performance or utilize effect can produce direct influence, therefore in order to satisfy the requirement on settled date, should require a bit in the heliostat device operation process, maintaining static all the time in the level crossing, otherwise will there be inherent shortcoming in heliostat device, influence tracking accuracy.
Existing heliostat device generally adopts the two intersecting axle mechanical transmission mechanisms that can produce compound motion to drive, and the transverse axis mechanism in two intersecting axles is superimposed upon in the vertical shaft mechanism.Because structure limited (for example in order to avoid transverse axis), the geometric center point of level crossing can only be designed to the position of as far as possible close two intersecting axle intersection points, does not therefore all satisfy above-mentioned requirements basically--a bit in the heliostat device operation process, maintaining static all the time in the level crossing.As a result, in operation process, can only ignore the error that causes thus in fact, can only allow receiver tolerate this error when designing in other words.
This level crossing departs from the systematic error notion that error that ideal position causes can use in the physics explains, or is further defined as intrinsic systematic error.For example, the heliostat device that adopts in sun I number of building up in the Southern California of the U.S. and the II number tower electricity generation system has adopted typical two intersecting axle mechanical transmission mechanisms, wherein the transverse axis mechanism rack is located in the vertical shaft mechanism, but the level crossing general frame all is installed on the transverse axis, about 150 millimeters away from distance of transverse axis axis be of level crossings--there is intrinsic systematic error.
When the heliostat device area was big, transverse axis was in order to bear bigger load, the corresponding overstriking of diameter, and the systematic error of device itself will be big more as a result.
In addition, the transverse axis and the vertical shaft two axial lines itself of existing heliostat device also usually are the non-space quadrature, thereby have further aggravated the intrinsic systematic error of heliostat device.
Facts have proved that the existence of this intrinsic systematic error makes heliostat to follow the tracks of the sun by approximate rule, in any case mate the position of alignment sensor and take which kind of remedial measure, all can not satisfy the requirement that pinpoint accuracy is followed the tracks of.
Summary of the invention
The technical problem to be solved in the present invention is: at the shortcoming that above prior art exists, propose a kind of eliminate above-mentioned intrinsic systematic error heliostat device, thereby significantly improve tracking accuracy, satisfy the designing requirement that modernized solar energy utilizes facility.
In order to solve above technical problem, heliostat device of the present invention comprises the level crossing group that is installed on the general frame, drive the azimuth guiding mechanism that general frame rotates around the vertical shaft axis, be superimposed upon on the guiding mechanism of azimuth, drive the elevation angle guiding mechanism that general frame rotates around the transverse axis axis, alignment sensor, and be input with the alignment sensor, control the control circuit of above-mentioned guiding mechanism drive motors corner, it is characterized in that: the axis of described transverse axis and vertical shaft is positioned at same plane and intersects vertically, the geometric center of described level crossing group is positioned at the intersection point of described two axial lines, and the line between the center line of described alignment sensor and two axial lines intersection point and the projection target's center's point overlaps.
After adopting above technical scheme of the present invention, how does not move at each position of pipe unit, the geometric center physical location of level crossing is motionless all the time, had real motionless physical space central point just because of single unit system, and between heart point and the impact point alignment sensor has been installed hereinto, therefore eliminated the intrinsic systematic error that prior art exists, there is not theoretical error in the mechanism design that had both realized whole device, thereby the sunshine that is guaranteed to incide on the level crossing can accurately be invested impact point after reflection all the time.
