Description
Technical field
The present invention relates to correcting device and method, a kind of heliostat calibration equipment and the bearing calibration that movably can proofread and correct heliostat in real time of specific design to the solar energy tracking robot scaling equipment.
Background technology
Heliostat is to be used for the light of the sun or other celestial bodies is reflexed to the optical devices of fixed-direction, it reflects sunshine by follower and gathers a certain target, and existing heliostat comprises five major parts such as catoptron, support frame, column, transmission and tracking data disposal system.Yet in the use of heliostat, because the influence of various factors, the degree of accuracy of its follower may descend to some extent, causes the reflected light of sunshine not reflex to the target location, and this just need calibrate the precision of heliostat.
Trimming process to heliostat is exactly in fact the process that obtains the rotation center of heliostat, in the process of heliostat to the sun light tracking reflection, orientation-following in elevation is modal mode, the orientation turning axle (vertical pivot) of heliostat and pitching turning axle (transverse axis) are orthogonal, and the rotation by two axles cooperates the rotary courses that can make heliostat finish 360 degree.
The correcting device of multiple heliostat is disclosed in the prior art, a kind of bearing calibration and means for correcting thereof of heliostat are disclosed as Chinese patent literature CN 102077035A, while provide a kind of can to the minute surface of the minute surface of heliostat and central reflector over against situation survey method of adjustment and the adjusting gear of adjusting then and there.In the technique scheme, has central reflector on top and the bottom has the portion of being heated, around central reflector, dispose the heat collector of many heliostats, on the light path of top focus that links central reflector and heliostat, be provided with irradiation unit to this central reflector and heliostat difference irradiating laser, near laser irradiation device, be disposed with the infrared rays receiver that the emission laser from the heliostat reflection is detected, and means for correcting possesses the adjusting gear that makes this irradiation unit and infrared rays receiver rotation and pitching.In trimming process, form the mode of same axis with the reflected light and the laser that is irradiated to the top focus of central reflector of the laser that is irradiated to heliostat, adjust the angle of pitch and/or the rotation angle of heliostat.
In use there is following problem in above-mentioned heliostat calibration equipment:
At first, above-mentioned heliostat correcting device is when infrared rays receiver receives the heliostat laser light reflected, because light-receiving area is less, the beam diameter of laser-bounce light is also very little, so infrared rays receiver seizure reflector laser has difficulties the bigger difficulty of process existence that makes correction; When whether definite laser shone on the central reflector, by artificial observation, naked eyes were judged, have certain error in addition.
Secondly, in the technique scheme, the correcting device of each group heliostat once can only be calibrated a heliostat, though laser instrument can be pulled down the position that is installed to other then from support calibrates other heliostat, but complicated operating process, in the time need calibrating a large amount of heliostats, this complicated processes is consuming time very long, and correction efficient is low.
In addition, existing Chinese patent literature CN 101903818A discloses a kind of mounting position measuring device, providing a kind of is coupled in the operation of revolving conic surface at the catoptron that heliostat is installed, in order to carry out efficient and easy installation adjustment, correctly measure the method for adjustment and the mounting position measuring device of the mounting position of lower plane mirror.In the method that the catoptron that constitutes the heliostat that sunshine optically focused uses is set, the imagination that arrives the laser spots determination part with the laser-bounce light of facet mirror is provided with above-mentioned facet mirror by the mode of point.Laser beam emitting device in the technique scheme is installed on the supporting member, and supporting member is provided with movable mechanism, cooperates the adjustment that realizes facet mirror setting angle by laser beam emitting device and laser receiver.
Mounting position measuring device in the such scheme is applied to install in the catoptron process of heliostat, after the focal position of heliostat is determined, the direction of incident laser is known, so reflector laser to reflex to the focus of heliostat must be through the image point in the laser note survey portion, and when this process of execution, must guarantee that the relative position between supporting member and the heliostat is that determined value just can carry out, when heliostat rotates or owing to use when having produced error in rotary course for a long time, deviation may take place in the focal position, variation may take place in the angle of incident laser and catoptron, variation has also taken place in the image point that reflector laser will pass through, said process just need redeterminate, so said apparatus can not be realized the real-time correction to the turning axle of heliostat; In addition, in the process of the mensuration of carrying out mounting position, whether needing constantly to attempt reflector laser, whether to put the position of judging installation by illusion accurate, and operating process is very loaded down with trivial details.
