The specific embodiment
Referring to Fig. 1, this embodiment of the utility model comprises the reflector 2 and the support 7 of thermal-collecting tube 1, cylinder shape, and thermal-collecting tube 1 is installed on the axis of reflector 2 and is supported on the support 7.Installation one driven sprocket 3 is all rotated by bearing in two ends at described thermal-collecting tube 1, and described reflector 2 is connected with this driven sprocket 3 by connecting rod 13; Described driven sprocket 3 is in transmission connection by transmission mechanism and motor; At the edge of described reflector 2 sensitive probe 8 (existing product) that is used to follow the tracks of sunshine is installed, this sensitive probe 8 is connected with described motor by controller.
Described transmission mechanism comprises power transmission shaft 9, decelerator 5 drive sprockets 4 and chain 14, in the bottom of described support 7 power transmission shaft 9 is housed, the drive sprocket 4 corresponding with described driven sprocket 3 is installed on this power transmission shaft 9, between this driven sprocket 3 and drive sprocket 4, is connected with chain 14.
The utility model passes through sensitive probe 8 real-time sensitization when work, photoreceptor signal is transferred to controller (not shown), judges and calculate the direction that reflector rotates that by controller sensitive probe feeds back in real time simultaneously, form closed-loop system with controller, make that control is more accurate.Controller will output signal to common electric machine 6, motor is by decelerator 5, power transmission shaft 9, drive sprocket 4, chain 14, driven sprocket 3 and connecting rod 13, transmit motion to reflector 2, make that reflector 2 and sunshine are synchronous in real time, sunshine is converged on the thermal-collecting tube 1.
The utility model adopts 4 rev/mins common reducing motor 6, and is equipped with the decelerator 5 realization double reduction and the self-lockings of 1: 60 speed reducing ratio, so the power of motor 6 is very little, passes through multi-stage speed-reducing in addition, and tracking accuracy can be controlled in 0.2 °.
The utility model also can be on the basis of above-mentioned single one dimension heat collector, two-dimension tracing apparatus is equipped with at middle part in described support 7 lower ends, this two-dimension tracing apparatus comprises two-dimensional tracking decelerator 10, two-dimensional tracking motor 12 and two-dimensional tracking output shaft 11, two-dimensional tracking motor 12 is in transmission connection by two-dimensional tracking decelerator 10 and two-dimensional tracking output shaft 11, this two-dimensional tracking output shaft 11 is connected with described support 7, and this two-dimensional tracking motor 12 is connected with two-dimensional tracking sensitive probe (not shown) with the controller of a two dimension.Make original system become the two-dimensional tracking system, make the real-time vertical irradiation of its real realization.Such system can not do very greatly, and its meaning also is to realize small-sized pilot system or test platform, and the measurement of the vertical irradiation level of the sun.Certainly thermal-collecting tube can be placed incessantly on it, any heat collector or cell panel and various instrument that needs vertical irradiation can also be placed.
Referring to Fig. 2, the utility model can be connected into one group of shared drive motors 6 and decelerator 5 with 3 to 5 heat collectors shown in Figure 1 (not comprising two-dimensional tracking decelerator 10, two-dimensional tracking motor 12 and two-dimensional tracking output shaft 11), be connected into a big collecting system with several groups again, thereby use a cover circulatory system.This collecting system can be placed according to different things of latitude or north and south.
The utility model also has following characteristics:
1 the utility model thermal-collecting tube 1 is placed on the focal line of reflector 2, and thermal-collecting tube 1 is fixed on the support 7, and reflector 2 rotates around thermal-collecting tube 1, and reflector can reflex to the light of vertical irradiation on the thermal-collecting tube 1 at any time.
The mode that 2 the utility model adopt single drive source (motor 6 and decelerator 5) two ends to drive makes the two ends synchronized movement, has more avoided many drawbacks such as single-ended drive restriction heat collector 1 length.
By chain transmission campaign, that heat collector 1 and reflector 2 can be done like this is very big, can not be subjected to the restriction of transmission range as gear drive between 3 the utility model drive sources and the executive component reflector 2.
4 the utility model can replace the position that travel switch in the past feeds back reflector at the installation transversal switch (not shown) on the sensitive probe 8, improve the stability of system.
The real-time feedback that 5 the utility model adopt common electric machine 6 to add sensitive probe 8 is worked under lower-speed state and is replaced stepper motor, greatly reduces cost.
6 the utility model can be connected into 3 to 5 heat collectors 1 one group of shared drive source, are connected into a big collecting system with several groups again, thereby use a cover circulatory system.
