Specific embodiment
Photovoltaic and photothermal device is equipped at least one piece fixed photovoltaic panel 1 of inclination, is typically provided with muti-piece photovoltaic panel 1, every block of light Being horizontally disposed on volt plate 1 has more cleaning branch pipes 2, wherein one is cleaned branch pipe 2 and is horizontally fixed on the upper eaves of photovoltaic panel 1, then its He cleans branch pipe 2 and is evenly distributed in photovoltaic panel 1, and only level is fixed, is uniformly distributed, and cleaning branch pipe 2 is almost attached to photovoltaic panel 1 On, it cleans and is uniformly provided on branch pipe 2 for the hole of (gas) of spraying water along every, the underface or side of cleaning branch pipe 2 is arranged in hole Water is sprayed to 1 upper surface of photovoltaic panel in lower section
One end of every cleaning branch pipe 2 is connected to vibration means for main pipe for supplying water 3, other end closing, the water inlet end connection of vibration means for main pipe for supplying water 3 The outlet of three-way magnetic valve 4, one of import of three-way magnetic valve 4 connect water pump 5, and water pump 5 connects water source 6, from water source 6 Water is pumped out, water source 6 can be water tank, boiler, tap water etc., hot water can be sprayed in photovoltaic panel 1 by water pump 5, and High pressure is generated, the dust in photovoltaic panel 1 can be efficiently removed very much.
Another import of three-way magnetic valve 4 connects air pump 7, and air pump 7 can be blown into vibration means for main pipe for supplying water 3 and cleaning branch pipe 2 Gas, there are two effect, the first removal vibration means for main pipe for supplying water 3 and the ponding for cleaning branch pipe 2 for high pressure gas tool, when can be to avoid use in winter Water pipe ice blockage, second can blow to 1 surface of photovoltaic panel, quickly blow away the ponding on 1 surface of photovoltaic panel, utilize high-pressure water gas Also it can be further improved dust elimination effect, can freeze to avoid 1 surface of (night in winter) photovoltaic panel.
System is equipped with dust accumulation induction mechanism, as shown in Figure 1, dust accumulation induction mechanism is equipped with glass 8, is fixed on photovoltaic panel 1 The tilt angle of neighbouring open air, every piece of photovoltaic panel 1 is generally identical, and dust accumulation induction mechanism is equipped with and 1 tilt angle phase of photovoltaic panel Same glass 8, glass 8 are the plate structure of transparent glass, and for experiencing the dust accumulation of environment, 8 lower surface of glass is solid Surely there are light source 10, the preferred l ed light source 10 of light source 10,8 upper surface of glass is fixed with the light intensity that induction light source 10 issues intensity of illumination Inductor 9, the induction end of light intensity inductor 9 face light source 10 obliquely, and a circle barn door is equipped with around induction end, avoid It is influenced by ambient light, light intensity inductor 9 exports inductive signal to controller, controller output drive signal to light source 10, since the intensity of illumination that light source 10 issues is fixed, then the height that illumination intensity value can be received by light intensity inductor 9 judges 8 surface dust accumulation thickness of glass.The light source 10 and light intensity inductor 9 that about 8 glass matches are set at least provided with two groups by redundancy Meter, can to avoid bird fly etc. special circumstances to test dust after influence.
Eaves is fixed with a horizontally disposed cleaning branch pipe 2 on glass 8, which is connected to vibration means for main pipe for supplying water 3, in this way Glass 8 can be cleaned simultaneously when cleaning photovoltaic panel 1, precipitation rain fall sensor is fixed on glass 8, controller is additionally provided with inductance loop The environmental light intensity sensor of border light intensity, precipitation rain fall sensor and environmental light intensity sensor export inductive signal to controller.Rainfall passes Sensor can incude currently whether rain, can to avoid rain during light intensity inductor 9 false judgment, environmental light intensity sensing Device is then used to incude environmental light intensity, the inaccuracy that can be tested to avoid light intensity inductor 9 under strong light environment.
Based on the control method of the dust pelletizing system, control method includes:
Three-way magnetic valve 4 is controlled after starting dedusting function and is only connected to water pump 5, drives water pump 5 to start to work later;
After 5 operation setup time of water pump, 5 are switched off the pump, control three-way magnetic valve 4 is only connected to air pump 7, opens air pump later 7;
After 7 operation setup time of air pump, air pump 7 is closed.
It first washes by water, then blows, can greatly improve dust removing effects in the case where water conservation.
In order to start dedusting function automatically, the distance last time for opening light source 10 reaches setting value, and works as front ring Border light intensity is lower than setting value, then opens primary source 10, and light source 10 opens setting time, light intensity induction in 10 opening process of light source Device 9 obtains light source 10 and does not start dedusting function, if illumination if intensity of illumination is higher than setting value through the intensity of illumination of glass 8 Intensity, which is lower than, is equal to setting value, then starts dedusting function.
It is currently raining when precipitation rain fall sensor is got, is then opening 7 setting time of air pump at interval of setting time, in this way It can achieve the effect that high-efficient cleaning using rainwater, even a small amount of rainwater except dust, in addition, when precipitation rain fall sensor gets what rain stopped After signal, 7 setting time of air pump is opened, the primary air blowing after rain stops can be avoided the influence power generation of 1 surface area water of photovoltaic panel, and energy Guarantee the accuracy of 8 surface light intensity inductor 9 of glass test;If preceding raining, suspends the timing to light source 10 is opened, also can The induction of light intensity inductor 9 is avoided error occur.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements not by aforesaid way Limitation, as long as the improvement for the various unsubstantialities that the inventive concept and technical scheme of the present invention carry out is used, or without changing It is within the scope of the present invention into the conception and technical scheme of the invention are directly applied to other occasions.
