Abstract
The utility model provides a photovoltaic board cleanliness detector, mainly by the support, the he -Ne laser instrument, convergent lens, photoelectric detector and control circuit module constitute, the he -Ne laser instrument, convergent lens, photoelectric detector and control circuit module pass through the screw fixation on the support, the support passes through screw fixation in photovoltaic board side, the cleanliness that the photovoltaic board is confirmed to scattered light that laser beam that the laser instrument sent produced was received on photovoltaic board surface according to photoelectric detector to the detector. The utility model discloses it is small, portable, convenient to use, the cleanliness of measurement photovoltaic board that can be quick, convenient can provide the cleanliness data of real -time quantification for photovoltaic power plant.
Description
Technical field
The utility model relates to a kind of cleanliness pick-up unit of solar photovoltaic power plant photovoltaic panel, refers in particular to a kind of photovoltaic panel cleanliness detector.
Background technology
Since entering the new century, fossil fuel is increasingly rare, and solar energy power generating is more and more subject to people's attention as a kind of main green energy resource and is widely used.Photovoltaic plant mainly completes photoelectric converting function, and wherein solar energy photovoltaic panel is the significant points of sun power conversion.But in actual applications; solar energy photovoltaic panel is generally arranged on place abundant, short of rain at sunshine; the local dust storm at most of solar power station place is larger; dust granule can drop on battery surface, gets off to make photovoltaic panel to cover with one deck dust for a long time, thus affects the transmissivity of light; photoelectric transformation efficiency is reduced; the shade that pollutant is formed also can make assembly produce hot spot effect, causes assembly life-span to reduce, therefore needs to clean in time photovoltaic panel.
In order to make staff clear up in time the dust stratification in photovoltaic panel, particularly important to the detection of photovoltaic panel cleanliness.Not only the photovoltaic panel cleanliness data of a real-time quantization can be provided for photovoltaic plant to the detection of photovoltaic panel cleanliness, and the generated energy data affected by cleanliness at present, foundation can be provided for when photovoltaic plant carries out cleaning again, be convenient to the management of photovoltaic plant.
Utility model content
The utility model provides a kind of photovoltaic panel cleanliness detector, can provide the photovoltaic panel cleanliness data of a real-time quantization for photovoltaic plant, also when can carry out cleanly providing foundation for photovoltaic plant.
The technical solution adopted in the utility model is:
A kind of photovoltaic panel cleanliness detector, be made up of support, He-Ne laser instrument, convergent lens, photodetector and control circuit module, it is characterized in that: described He-Ne laser instrument, convergent lens, photodetector and control circuit module are all screwed on support, described support is screwed in photovoltaic panel side, the adjustable angle between described support and photovoltaic panel.
Reflection and scattering is there is in the laser beam that described He-Ne laser instrument sends on photovoltaic panel surface, photoelectric detector through convergent lens focus on after scattered light signal and be converted into electric signal, control circuit module carries out A/D conversion and signal transacting to the electric signal of gained, and described detector obtains the cleanliness of photovoltaic panel according to the electrical signal intensity after control circuit resume module.
Described photodetector along support up-down adjustment, can ensure that the scattered light that photoelectric detector arrives is the strongest.
Described support height is 30cm.
The beneficial effects of the utility model are: the utility model volume is little, is easy to carry, easy to use, can measure the cleanliness of photovoltaic panel fast, easily, can provide the cleanliness data of real-time quantization for photovoltaic plant.

Fig. 1 is structural representation of the present utility model.(1) for support, (2) be He-Ne laser instrument, (3) be convergent lens, (4) are photodetector, (5) are control circuit module.
Embodiment
Below with reference to shown in accompanying drawing and embodiment the utility model is described in detail.
As shown in Figure 1, the utility model provides a kind of photovoltaic panel cleanliness detector, be made up of support (1), He-Ne laser instrument (2), convergent lens (3), photodetector (4) and control circuit module (5), it is characterized in that: described He-Ne laser instrument (2), convergent lens (3), photodetector (4) and control circuit module (5) are all screwed on support (1), described support (1) is screwed in photovoltaic panel side.
Reflection and scattering is there is in the laser beam that He-Ne laser instrument (2) sends on photovoltaic panel surface, the scattered light signal after convergent lens (3) focuses on that photodetector (4) receives also is converted into electric signal, control circuit module (5) carries out A/D conversion and signal transacting to the electric signal of gained, and cleanliness detector obtains the cleanliness of photovoltaic panel according to the electrical signal intensity after control circuit module (5) process.
The using method of photovoltaic panel cleanliness detector:
1, with screw, detector is fixed on photovoltaic panel side;
2, cleanliness detector is demarcated---photovoltaic panel cleaned up, open laser instrument, the scattered light signal regulating photodetector (4) and convergent lens (3) that photodetector (4) is received is the strongest;
3, photovoltaic panel cleanliness are measured in real time.
Those of ordinary skill in the art will be appreciated that; the above is only used to the utility model is described; not in order to limit the utility model; every within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
Claims (3)
