Described pitching Drive Structure one mainly is made of pitching rotational delay device 10, and the rotating output shaft of pitching rotational delay device 10 is coaxial fixing with transition bevel gear 2.
Described pitching Drive Structure two mainly is made of linear actuator 11, and the stiff end of linear actuator 11 is fixed on the axis of reflection 5, and its nut tache motorice is connected with pinion stand 4.
Described reflection cone gear 1, transition bevel gear 2, incident bevel gear 3 can be the bevel gears of any kind, can be that straight bevel gear or helical bevel gear also can be curved cone gears etc.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.
Described reflection cone gear 1, transition bevel gear 2, incident bevel gear 3 are that complete angular wheel or part is the gear of taper.Because of the angle of the required rotation of the utility model gear only needs 120 ° ~ 180 °, need not 360 °, part has bevel gear to meet the demands.
Described reflection cone gear 1 and incident bevel gear 3 are bevel gear wheel or bevel pinion, and transition bevel gear 2 is corresponding with the first two bevel gear.
Described reflection cone gear 1 is identical with incident bevel gear 3 types, modulus is identical, the number of teeth is identical, pitch cone angle is identical, transition bevel gear 2 is corresponding with reflection cone gear 1, transition bevel gear 2 is corresponding with incident bevel gear 3, the number of teeth of transition bevel gear 2 and reflection cone gear 1 are identical or different, the number of teeth of transition bevel gear 2 and incident bevel gear 3 are identical or different, and transition bevel gear 2 only need select to satisfy with the first two bevel gear the bevel gear of meshing condition.
Operation principle of the present utility model is as follows: reflection cone gear 1 and the engagement transition of incident bevel gear 3 by transition bevel gear 2, the two relative pinion stand 4 anglec of rotation is identical but direction is opposite, has satisfied the corresponding relation between incident ray and reflection ray and the speculum normal.As Fig. 5 (a), 5(b), 5(c), 5(d) shown in, axial line A is vertical with axial line B, can get such result according to the theory of engagement of bevel gear between each bevel gear among the figure: regardless of initial position relatively, after reflection cone gear 1 and the engagement transition of incident bevel gear 3 by transition bevel gear 2, when rotating vertically, pinion stand 4 anglecs of rotation (being total number of teeth in engagement) are identical relatively, and direction of rotation is opposite, i.e. β=β '.During running, at first the axially-extending line of axis of reflection 5 is aimed at tower heat collector center, and itself and main rotational delay device 9 are connected and fixed firmly, and it can only be done around axially rotatablely moving.Again pinion stand 4 and heliostat 8 are connected firmly, make the passive automatic sun-tracing support of this tower type solar heliostat bevel gear carry out the actuation movement of pitch orientation.The driving of pitch orientation of the present utility model has two kinds of embodiment, and is as follows.
Embodiment one, as depicted in figs. 1 and 2: pitching rotational delay device 10 is installed on the pinion stand 4, its rotating output shaft transition bevel gear 2 is coaxial fixing, transition bevel gear 2 will be as the active drive power source of this support pitch orientation, and the positive and negative rotation of pitching rotational delay device 10 will make heliostat 8 do elevating movement.
Embodiment two, as shown in Figure 3 and Figure 4: the stiff end of linear actuator 11 is fixed on the axis of reflection 5, its nut tache motorice is connected with pinion stand 4, this moment, linear actuator 11 was also as the active drive power source of this support pitch orientation, and the front and back rectilinear motion by linear actuator 11 nuts will drive heliostat and do elevating movement.
Rotatablely moving and the elevating movement of pitching rotational delay device 10 or linear actuator 11 of main rotational delay device 9 by this support makes the photoelectric probe 7 on the incident axle 6 aim at sunlight direct projection directions like this.According to the movement relation of the relevant reflection cone gear 1 in front and incident dimension gear 3 and pinion stand 4, sunlight just can and make the axial ejaculation of reverberation along axis of reflection 5 along incident axle 6 directive heliostats like this, and directive tower type solar heat collector center.Thereby another brand-new angle of the utility model designs the follower of tower type solar heliostat, with the complexity debugging that simple structural approach has solved existing various tower type solar heliostat tracking systems, the problem that installation and control is loaded down with trivial details.
In addition, because the passive automatic sun-tracing support of this tower type solar heliostat bevel gear is a semi-closed loop system, as long as the mechanical precision of 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 the utility model content.The used drive motors of the utility model only needs general brush direct current motor to get final product, even the cheap toy direct current machine of the utility model use also is feasible.So the required precision of mechanical transmission component has also been reduced much because be this device of semi-closed loop system.
To sum up, the utility model has improved the precision of heliostat to solar tracking, simplified heliostat control program and method, the price that has reduced heliostat two dimension carriage drive tracking system part is proportion in the price of whole heliostat system, is worthy of popularization.
