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
