As Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, comprise axis of reflection 5 among the figure, incident axle 6, heliostat 8 and photoelectric probe 7, this device also comprises reflection cone gear 1, transition bevel gear 2 and incident bevel gear 3, reflection cone gear 1 and incident bevel gear 3 concentrics, axial and the reflection cone gear 1 of transition bevel gear 2, incident bevel gear 3 axially vertical, reflection cone gear 1 and 2 engagements of transition bevel gear, transition bevel gear 2 and 3 engagements of incident bevel gear, reflection cone gear 1 can not have any type of engagement to contact with incident bevel gear 3, reflection cone gear 1, transition bevel gear 2 and incident bevel gear 3 place on the pinion stand 4, reflection cone gear 1 is connected with axis of reflection 5 relative fixed, incident bevel gear 3 is connected with incident axle 6 relative fixed, initial engagement position between its two combiner and the corresponding transition bevel gear 2, should decide on the concrete structure of this device with two dimensional scaffold relative installation, its principle is: only otherwise the normal operation that influences two dimensional scaffolds gets final product.
Photoelectric probe 7 is installed on the incident axle 6, and follows the concrete structure according to two dimensional scaffolds, guarantees that photoelectric probe at any time and the position, does not all keep the sun off.Pinion stand 4 places on the heliostat 8, no matter the O point of the automatic conversion control device of this heliostat light angle, be existing two dimensional surface support tracking system or two-dimentional push rod connecting rod rack tracking system if being overlapped with the two-dimentional rotating shaft joint of heliostat two dimensional scaffolds.Axis of reflection 5 is rotary with connecting rod 9 and is connected, and axially rotates along axis of reflection only, and connecting rod 9 is connected and fixation with ground with ground or by other parts.
As Fig. 2, Fig. 3 and shown in Figure 4, A is vertical with B among the figure, can get such result according to the theory of engagement of bevel gear between each bevel gear: regardless of initial position relatively, after reflection cone gear 1 and the engagement transition of reflection cone gear 3 by transition bevel gear 2, when rotating vertically, relative pinion stand 4 anglecs of rotation (being total number of teeth in engagement) are identical but direction of rotation is opposite, i.e. β=β '.
Reflection cone gear 1 and incident bevel gear 3 needs with modulus of the same type, same, the same number of teeth, with the bevel gear of pitch cone angle, transition bevel gear 2 because of with the first two bevel gear engagement, so must select the bevel gears of satisfied and the first two all meshing condition of bevel gear; Reflection cone gear 1 and incident bevel gear 3 can be chosen as bevel gear wheel, also can be chosen as bevel pinion, and then transition bevel gear 2 will be corresponding with the first two bevel gear; Transition bevel gear 2 numbers of teeth can be identical with the first two bevel gear also can be different; As long as the pitch cone angle of all bevel gears meet in theory meshing condition all can, adopt the bevel gear of pitch cone angle Σ=90 ° usually.Reflection cone gear 1, transition bevel gear 2 and incident bevel gear 3 are straight bevel gear or helical bevel gear or curved cone gear.
Reflection cone gear 1, transition bevel gear 2 and incident bevel gear 3 can be complete angular wheel, also can local be the gear of taper.In use, reflection cone gear 1 engagement transition bevel gear 2 only needs to guarantee that gear motion partly is local angular wheel that the gear motion that also needs simultaneously to guarantee incident bevel gear 3 engagement transition bevel gears 2 partly is local angular wheel.Can save cost like this, also can not lower efficiency simultaneously.
This tower type solar heliostat bevel gear light angle conversion control device needs bevel gear seat 4 is installed on the heliostat 8, and guarantee reflection cone gear 1 and the axle center of incident bevel gear 4 and the joint O of axis of reflection axis of rotation, coincide with the joint of two dimensional scaffold pitching rotating shafts and orientation rotating shaft.Behind this device axis of reflection 5 aligning tower type solar heat collector centers, again axis of reflection 5 and connecting rod 9 are connected, guarantee that axis of reflection 5 rotates vertically only, at last connecting rod 9 is fixed in ground or is connected also fixation with ground by other parts.By the photosignal that the photoelectric probe 7 that is installed on the incident axle 6 detects, control the rotation and the elevating movement of two dimensional scaffolds, under the Union Movement of the two, adjust the position of incident axle 6, make photoelectric probe 7 point to the sun all the time.Under the motionless situation of axis of reflection 5 axial restraints, thereby driven pinion stand 4 relative incident axles 6 and axis of reflection 5 makes equal angles but rightabout rotatablely moves, and driven axis of reflection 5 and rotate vertically.So just guarantee that sunlight is along incident axle 6 directive heliostats 8 and make the axial ejaculation of reverberation along axis of reflection 5, because described in axis of reflection 5 embodiment in front be: rotate only vertically, this axially-extending line is aimed at tower type solar heat collector center, so reflection ray will point to tower type solar heat collector center all the time.
For realizing above-mentioned target, generally require the two-dimentional rotating shaft of existing heliostat two dimensional scaffolds that joint will be arranged, and with the O point of the automatic conversion control device of this heliostat light angle therewith joint overlap, no matter be existing two dimensional surface support tracking system or two-dimentional push rod connecting rod rack tracking system, the automatic conversion control device of this heliostat light angle all can be installed as long as satisfy above-mentioned requirements.These device installation and operation regulation and control are very simple, improved the precision of heliostat to solar tracking, heliostat control program and method have been simplified, existing heliostat control program will comprise longitude and latitude according to the concrete installation site of heliostat, decide with the locus of collector and orientation, season, time, and fibrous root then need not to consider above-mentioned factor according to the annual do correction of astronomical information adjustment if this device has been installed.The type of drive of existing heliostat two dimensional scaffolds is simplified, and the requirement on machining accuracy of the mechanical part of this part is greatly reduced, the driving tracking system of former heliostat two dimensional scaffolds is not to be exactly to use servomotor with stepper motor, some also need have accurate positioning elements such as code-disc, no matter these motors and accurate positioning element are motor itself or the neither phenanthrene of controller price, the required precision of adding mechanical transmission component is also very high, so the price of existing heliostat two dimension carriage drive tracking system part proportion in the price of whole heliostat system is generally higher, if load onto this device then this expense will reduce greatly.Because the automatic conversion control device of this heliostat light angle is a semi-closed loop system, as long as the mechanical precision of this device itself is guaranteed by designing requirement, by above-mentioned description, just can guarantee that sunlight is radiated on the tower type solar heat collector all the time by the reflection of heliostat to content of the present invention.And the used drive motors of the present invention only needs general brush direct current motor get final product, if with dc brushless motor the service life of system and maintenance cycle are extended certainly, even the present invention to use the toy direct current generator of cheapness also be feasible.So the required precision of mechanical transmission component has also been reduced much because be this device of semi-closed loop system.
