Description
Technical field
The utility model belongs to field of photovoltaic technology, is specifically related to the photovoltaic tracking technology be applied in photovoltaic apparatus, has more specifically to a kind of the photovoltaic frame that driving mechanism is followed the tracks of in low-power consumption.
Background technology
Along with the energy day by day deficient and environmental protection demand enhancing, photovoltaic energy is valued by the people all the more as a kind of clean reproducible energy.
Energy conversion technology and ray tracking technology are the two large key technologies improving photovoltaic utilance.Photovoltaic apparatus is generally made up of the photovoltaic module based on photovoltaic panel and photovoltaic frame, following-up type photovoltaic frame can the rotation support portion of relative fixed support partial turn be grouped into to be arranged in fixed support part by fixed support part, and photovoltaic module is then fixedly mounted in rotational support part.Ray trace refers to that drive units such as utilizing motor drives the rotational support part in photovoltaic frame to drive photovoltaic module to rotate to make photovoltaic panel keep vertical light to inject direction with transmission mechanism composition driving mechanism.
At present, the driving mechanism that ray trace system adopts is varied, respectively have advantage, but its common drawback is, all needs the drive motors of relatively high power to drive relatively heavier photovoltaic frame action.Make ray trace system in ray tracing process, consume a large amount of energy.Reduce the efficiency of light energy utilization.
Summary of the invention
The utility model object is, for the driving mechanism above shortcomings of existing ray trace system, provides a kind of ray trace drive scheme of more low-power consumption.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of have the photovoltaic frame that driving mechanism is followed the tracks of in low-power consumption, comprise stand and crossbearer, stand upper end is assemblied in rotationally in the middle part of described crossbearer, it is characterized in that, electric machine is installed in stand, and pull rope installs around on the output of electric machine or the rotating shaft that is connected with electric machine output, and pull rope two ends are connected with the both sides of crossbearer respectively.
The utility model connects pull rope and drives crossbearer to rotate by the mode of tractive in crossbearer end, take full advantage of the leverage of crossbearer itself, substantially reduce the requirement to electric machine max. output torque.Achieve the motor of very little power output to the driving of huge photovoltaic frame.Ensure that photovoltaic frame entirety has good wind resistance and stability simultaneously.
In addition, the utility model adopts pull rope to substitute the transmission mechanisms such as gear used in the prior art, worm and gear, connecting rod, and the simple cost of structure is low.
Further, electric machine output is provided with assembling axostylus axostyle, and pull rope multiturn on assembling axostylus axostyle is wound around, and wherein a place is relative fixing with assembling axostylus axostyle to be wrapped in the pull rope assembled on axostylus axostyle.
In the utility model, the installation site difference of electric machine has relatively different effects.Generally, described electric machine can be arranged in the middle part of stand, and the pull rope two ends walking around electric machine output are upwards directly connected with crossbearer both sides.
As improvement, described electric machine is preferably arranged on stand top, two supports are set up on stand top separately to both sides, support is respectively provided with fixed pulley, are connected after the fixed pulley of stand both sides is walked around at the pull rope two ends walking around electric machine output respectively with crossbearer sidepiece again.
As a distortion, stand installs two fixed pulleys below corresponding electric machine, install around two of first downwards walking around respectively in stand at the pull rope two ends of electric machine output fixed sliding after be connected to crossbearer both sides obliquely respectively again.
This improvement mounting structure not only makes overall structure compacter, the more important thing is, improve the minimum altitude of electric machine and pull rope, the impact of the part such as electric machine and pull rope on other operation below photovoltaic frame can be reduced, such as, photovoltaic frame is in the fields installed, improves the minimum altitude of electric machine and pull rope, electric machine and pull rope can be avoided to affect large-scale farm machinery in Tanaka's operation.

Embodiment
With reference to accompanying drawing 1-2, described in the utility model have the photovoltaic frame that driving mechanism is followed the tracks of in low-power consumption, and be made up of stand 5 and crossbearer 1 and driving mechanism, crossbearer 1 is assemblied in stand upper end, and crossbearer can rotate relative to stand in the pitch direction according to its center line.Driving mechanism comprises electric machine 2, and electric machine is furnished with the reduction gear box of 1:60, and electric machine 2 is installed in the middle part of stand 5, and electric machine output is provided with assembling axostylus axostyle 6, and assembling axostylus axostyle is provided with short pin 7.Pull rope 3 is wound around multiturn on assembling axostylus axostyle 6, and wherein a circle walks around short pin 7 one circle, as shown in Figure 2.Described pull rope 3 two ends from assembled shaft rod up-leading go out upwards to both sides stretch out be connected to crossbearer 1 both sides quarter butt, the quarter butt of crossbearer both sides is provided with the pin for connecting pull rope.
About the assembling between electric machine output and pull rope, optionally, the output of electric machine also can establish a driving wheel, and described driving wheel is for having toothed belt wheel or sprocket wheel.One section, pull rope centre is for having tooth driving-belt or driving-chain.One section, the centre cingulum of pull rope or chain match with the driving wheel of electric machine output.
In scheming, be of a size of example, both sides pull rope angle 58.4 degree, pull rope and stand angle 28.2 degree, pull rope is R1=876 to the torque arm length of crossbearer, electric machine output driving wheel radius R 2=25.If the maximum power output 20N of motor, after reduction gear box, is enlarged into F2=1200N.Can obtain according to F1/F2=R1/R2, electric machine up to F1=41616N, can be exaggerated more than 2000 times by pull rope to the maximum force of crossbearer.
That is, adopt drive mechanism of the present utility model, even if adopt the power that power output only has 20N, rotary resistance can also be driven to be the large-sized photovoltaic frame of 41616N.Similarly, extraneous wind-force will promote the rotation of photovoltaic frame, also needs the power of motor power output more than 2000 times, obviously effectively increases the wind resistance of frame.
With reference to Fig. 3-5, Figure 3 shows that the modified node method made on the basis of structure shown in Fig. 1, its maximum feature is the setting by fixed pulley 4, the installation site of electric machine 2 has been adjusted to the top of stand 5.Improve electric machine and the pull rope minimum altitude to map.
Be about 2M to improve front motor device apart from ground level, as shown in Figure 4, this height can meet freely walking of normal person, but cannot meet the current of some large-scale farm machineries.Arrange after fixed pulley improves, the minimum point at fixed pulley place is about about 3M apart from ground, as shown in Figure 5, so just can meet passing through, for the complementation of agriculture light provides more sound assurance of some large-scale farm machineries completely.As shown in Figure 6, in figure, dotted line is depicted as and highly raises front motor device and power transmission shaft position in contrast before and after electric machine installation site raises.
