Description
Technical field
The utility model relates to application of solar, especially a kind of solar panels tracking means.
Background technology
Solar energy is as a kind of energy of cleanliness without any pollution, and development prospect is boundless, has become the green energy resource that various countries competitively develop, but the sun exists that density is low, intermittent, direction of illumination and intensity is along with continuous problem such as variation of time.
Traditional solar panels mostly adopt fixed installation; Be that cell panel is fixed on an angle; Do not move, have a strong impact on photoelectric conversion efficiency, according to measuring and calculating with the variation of position of sun; If there are 25 ° deviation in power generation plate and angle of sun rays, will reduce the output that makes photovoltaic array because of the radiant energy of vertical incidence and descend about 10%.
Day every day rises sunset, and the lighting angle of the sun is at every moment all changing, and guarantee effectively that solar panel can be constantly over against the sun, and generating efficiency just can reach optimum state, and at this moment the effect of solar tracking system is particularly important.At present, domestic solar tracking system commonly used has the photoelectric tracing device, and the photoelectric tracing device is divided into gravity type, electromagnetic type and electrodynamic type again.These photoelectric tracing devices utilize light sensor, carry out the detection of sunlight like silicon photocell; In these devices, the installation of photoelectric tube makes shadow shield aim at the sun near shadow shield through the position of adjusting shadow shield, and silicon photocell is in the shadow region; The shade of shadow shield skew when the sun moves westwards, photoelectric tube receives little electric current of sunlight direct projection output certain value, as deviation signal, amplifies through amplifying circuit, by servomechanism adjustment angle the follow-up mechanism aligning sun is accomplished and is followed the trail of; Photoelectric tracing is highly sensitive; But receive the influence of weather very big, if light is faint or the situation that black clouds covers the sun occurs in long-time slightly section, sunray often can not shine on the silicon photocell; Cause follow-up mechanism can't aim at the sun, even can cause the malfunction of actuator; Moreover at present domestic solar panels commonly used are to come the support solar plate through the ball pivot that is arranged at solar panels bottom center, and such solar panels can arbitrarily angled in the past swing, and wind-force and external force all impact it.
The utility model content
The utility model provides a kind of solar panels tracking means, and it is not accurate enough that it can solve the prior art tracking, the problem that reliability is not high enough.
In order to solve the problems of the technologies described above; The technical scheme that the utility model adopted is: it includes solar panels and support; Said solar panels two ends are connected with said stent strut through rotating shaft; Wherein the said pillar of solar panels one end connection is connected with elevation angle rotating mechanism, and said elevation angle rotating mechanism is driven by driving mechanism, and said driving mechanism is controlled by the PLC controller.
In the technique scheme, scheme is more specifically: said elevation angle rotating mechanism can be turbine and worm; Said driving mechanism can be stepping motor.
Owing to adopted technique scheme, the utility model compared with prior art has following beneficial effect:
1, because the said pillar that solar panels one end connects is connected with elevation angle rotating mechanism; It can move with sun deviation post, can constantly follow the tracks of sunlight, improves photoelectric conversion efficiency; And the solar panels two ends are connected with stent strut through rotating shaft; It can only one-way brake like this, and can self-locking, has avoided the influence of wind-force and external force effect.
2, because driving mechanism by the control of PLC controller, cooperates step motor drive box drive stepping motor, simple in structure, easy for installation.
3, photoelectric tracing formula charging solar panel system adopts and controls solar charging panel one to one; And the utility model overlaps solar charging panels by a cover PLC controller control more, cost optimization, and in the PLC controller, enroll program; Faint or occur to be adjusted into static state under the situation that black clouds covers the sun at light in the long-time slightly section like this; Avoid too much loss, also can track the current time position automatically, and by the month fine setting; Can also eliminate the sun location tracking error, make things convenient for the renewal upgrading in later stage.

Fig. 2 is the left view of the utility model.
Fig. 3 is the vertical view of the utility model.
Embodiment
Below in conjunction with the accompanying drawing instance, the utility model is done further to detail:
Like Fig. 1, Fig. 2 and present embodiment shown in Figure 3, it includes solar panels 1 and support 2, is fixed with fixedly angle bar 3 under solar panels 1 two ends; Fixedly angle bar 3 is enclosed within on the rotating shaft 4, and rotating shaft 4 is installed in the bearing 6 on the column 5 at support 2 two ends, and one of them pillar is connected with elevation angle rotating mechanism; This elevation angle rotating mechanism is turbine 7 and worm screw 8; The power transmission shaft 10 of turbine 7 is connected with rotating shaft 4, and turbine 7 is driven by stepping motor 9, and stepping motor 9 is controlled by the PLC controller.
Solar panel rotates through worm and gear, and this rotation has defined the height drift angle of the sun, and one-way brake, has avoided the influence because of wind-force or other external force effects, guarantees the stability of its tracking.
By PLC controller control motor; Let this solar panel inquire about the corresponding sunrise sunset of current date at first automatically constantly, select the corresponding startup of tracker then automatically and stop the moment, then select the corresponding pulse frequency of tracker automatically in every morning; Inquire about the corresponding sun altitude of the current sun at last; Automatically adjust the back and get into automatic tracking mode, solar panels as time passes, sun east rises the west rotation tracking continuously that falls.And the month different is adjusted automatically, obtains solar energy to greatest extent.In the faint situation of the cloudy day sun alive, get into static schema.And can programme accordingly according to actual conditions, to eliminate the sun location tracking error in various sources, make things convenient for the improvement in later stage to upgrade.
