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 and particularly relates to a solar tracking mirror for solar power generation. The solar tracking mirror comprises a solar tracking mirror, a mounting support shell and a drive motor; when people utilize the solar tracking mirror designed by the invention, a speed reducer input shaft is driven to rotate through the drive motor; the speed reducer input shaft rotates a first speed reducer output shaft and the first speed reducer output shaft rotates; the solar tracking mirror swings around the axis of a first rotating shaftthrough rotation of the first speed reducer output shaft, thereby adjusting the elevation angle of the solar tracking mirror to adapt to the elevation angle, of tracking the sunlight, of the solar tracking mirror; the solar tracking mirror rotates around the axis of a first support ring through rotation of a second speed reducer output shaft, thereby making the solar tracking mirror spin to adaptto spinning, of tracking the sunlight, of the solar tracking mirror. According to the solar tracking mirror, pitching tracking and spinning tracking are achieved through the drive motor, and consumables of the solar tracking mirror in drive design are reduced.
Description
Technical field [0001] The invention belongs to the technical field of solar power generation, in particular to a heliotrope mirror for solar power generation. 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 pulse loss after p...
