Problems solved by technology
There are two main two-axis driving methods of the tracking mirror, which are the azimuth-pitch tracking mirror and the spin-pitch tracking mirror; the conventional azimuth-pitch tracking mirror indirectly calculates the dual axis through the motor pulse or encoder pulse combined with the initial position angle. The real-time inclination angle of the pitch tracking mirror has the disadvantage of low precision and pulse loss after power failure. It needs to be reset to recalculate the inclination angle, which is time-consuming; at the same time, two drive motors are required to drive; the cost of use is increased.

The invention belongs to the technical field of solar power generation, in particular to a tracking mirror with a crank device for solar power generation. The tracking mirror comprises a solar tracking mirror, an installation support case and a driving motor. When sun rises in the morning, sunlight will irradiate the solar tracking mirror, and when the irradiation angle of the sunlight is rightlyperpendicular to the solar tracking mirror, the solar tracking mirror will rotate under the driving of the driving motor. When the solar tracking mirror reaches the biggest angle in the rotation process, the solar tracking mirror will reversely rotate. When the solar tracking mirror recovers to the original position in the reverse rotating process, teeth on a second gear are engaged to a third gear. At this moment, the second gear rotates to allow the solar tracking mirror to swing around the axis of a support shaft so as to be suitable for elevation angle that the solar tracking mirror tracksthe sun in the second day. The tracking mirror achieves pitching tracking and self-rotation tracking through a driving motor, so consumed materials in driving design of the tracking mirror are reduced.
Description
Technical field [0001] The invention belongs to the technical field of solar power generation, in particular to a tracking mirror for solar power generation with a crank device. Background technique [0002] At present, the tracking mirror is generally used to superimpose the vertical rotating shaft on the horizontal rotating shaft. The tracking mirror is the concentrating device of the tower solar thermal power generation system, which is in charge of the front-end energy supply of the entire tower power station. Light is reflected and focused to a fixed target. There are two main two-axis driving methods of the tracking mirror, which are the azimuth-pitch tracking mirror and the spin-pitch tracking mirror; the conventional azimuth-pitch tracking mirror indirectly calculates the dual axis through the motor pulse or encoder pulse combined with the initial position angle. The real-time inclination angle of the pitch tracking mirror has the disadvantages of low precision and ...
