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.

specific Embodiment approach
[0059] The specific embodiment: when people use the tracking mirror designed by the present invention, first adjust the elevation angle of the sun tracking mirror 1 corresponding to the day in the morning; people control the driving motor 12 to change the acceleration of the driving motor 12; at this time, the shell of the driving motor 12 It will rotate relative to the output shaft of the drive motor 12; the rotation of the drive motor 12 shell will make the adjustment output shaft 11 rotate through the adjustment mechanism 2; the adjustment output shaft 11 will drive the second bevel gear 9 to rotate; the rotation of the second bevel gear 9 drives The first bevel gear 7 rotates; the rotation of the first bevel gear 7 drives the fixed shaft 6 to rotate; the rotation of the fixed shaft 6 drives the two second supports 10 to rotate around the fixed shaft 6; the rotation of the two second supports 10 drives around the fixed shaft 6 The support plate 5 rotates around the fixed sha...

The invention belongs to the technical field of solar power generation, and particularly relates to a solar power generation tracking mirror based on acceleration. The solar power generation trackingmirror includes a solar tracking mirror, an adjusting mechanism, a triggering mechanism, and a fixing installing shell. When people use the tracking mirror designed by the invention, the elevation angle of the solar tracking mirror is adjusted in the morning and corresponds to the day; the driving motor is controlled by people to change the acceleration of the driving motor, and then the elevationangle of the solar tracking mirror is adjusted; after adjustment is completed, the driving motor is controlled to enable the output shaft of the driving motor to rotate at a constant speed and the rotating speed is small; the output shaft of the driving motor rotates to enable the solar tracking mirror to rotate; and the solar energy is absorbed through the rotation of the solar tracking mirror.The tracking mirror is driven by a driving motor to drive the tracking mirror to perform two-axis driving, namely, the pitching tracking and the self-spinning tracking; and therefore the consumable ofthe tracking mirror on the driving design is reduced; the cost is saved, and the double-axis driving of the tracking mirror is realized.
Description
technical field [0001] The invention belongs to the technical field of solar power generation, and in particular relates to a tracking mirror for power generation using solar energy based on acceleration. 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 disadvan...
