System for washing intelligently solar heat collection plate
Technical field
The present invention relates to a kind of solar utilization technique, particularly a kind of system for washing intelligently solar heat collection plate.
Background technology
Solar heat-collection plate is good energy-saving equipment, is widely used in the hot-water heating system in family, enterprise, the building.But because solar heat-collection plate must place natural environment, it is good more to be beneficial to solar radiation more.A bit block arbitrarily and all can influence the thermal-arrest of solar heat-collection plate degree, in long term exposure was used, the solar heat-collection plate surface was easy to pile up dust, year in and year out, the dust of piling up has stopped the transmitance of sunlight, directly has influence on the conversion efficiency of solar heat-collection plate.
Traditional method is artificial cleaning solar thermal-arrest plate, but often solar heat-collection plate all is contained on the top layer of building, some pitched roof especially, and artificial the cleaning has certain danger; And the artificial uncertainty in addition of cleaning, the street cleaner has got on, and may find that the solar heat-collection plate surface is also relatively cleaner; And the street cleaner does not get on, and very thick dust has been piled up on possible solar heat-collection plate surface.
Summary of the invention
For remedying above-mentioned deficiency, the invention provides the system for washing intelligently solar heat collection plate that a kind of surface dirt of perception solar heat-collection plate is automatically piled up situation, cleaned and regularly clean automatically.
System for washing intelligently solar heat collection plate of the present invention, comprise water-line, wherein: described water-line connects a force (forcing) pump, described force (forcing) pump connects the shower that is horizontally placed on the solar heat-collection plate upper end, described shower has some spray apertures with respect to solar heat-collection plate one side, in solar heat-collection plate side or back microcomputer controller is installed, outside solar heat-collection plate, adorn first photosensitive probe, in the solar heat-collection plate watch crystal, adorn second photosensitive probe, described two photosensitive probes connect the input of described microcomputer controller respectively, and the output of described microcomputer controller connects described force (forcing) pump.
System for washing intelligently solar heat collection plate of the present invention, wherein: described microcomputer controller is made up of acquisition module, CPU, time block, Executive Module and TIP, and described computing module connects described acquisition module, time block, Executive Module and TIP respectively.
System for washing intelligently solar heat collection plate of the present invention can contrast according to the intensity of illumination that photosensitive probe detects, and determines the accumulation degree of solar heat-collection plate surface dirt, determines automatically to begin to clean; Can also regularly clean according to the setting of timer simultaneously.System for washing intelligently solar heat collection plate of the present invention has thoroughly solved the difficult problem that solar heat-collection plate cleans, and has reached not only to save but also convenient and practical purpose.
Description of drawings
Fig. 1 is the frame for movement schematic diagram of system for washing intelligently solar heat collection plate of the present invention;
Fig. 2 is the circuit block diagram of the computer controller of system for washing intelligently solar heat collection plate of the present invention.
The specific embodiment
For further setting forth system for washing intelligently solar heat collection plate of the present invention, do more detailed explanation below in conjunction with embodiment.
Fig. 1 is the mechanical schematic of system for washing intelligently solar heat collection plate of the present invention, therefrom can see, system for washing intelligently solar heat collection plate of the present invention comprises water-line 3, force (forcing) pump 2, shower 4 and computer controller 6.Force (forcing) pump 2 is connected water-line 3 and is horizontally placed between the shower 4 of solar heat-collection plate upper end, shower 4 and solar heat-collection plate surface are at a certain distance, use stent support, have some spray apertures 5 of arrangement in a row with respect to solar heat-collection plate one side, above solar heat-collection plate, begin to flow down with the water that guarantees spray, flow through the glass on whole solar heat-collection plate surface, fully cleaning solar thermal-arrest plate watch crystal.
In the solar heat-collection plate side or the back microcomputer controller 6 is installed, outside solar heat-collection plate, adorn first photosensitive probe 7, in the solar heat-collection plate watch crystal, adorn second photosensitive probe 8, two photosensitive probes connect the input of microcomputer controller 6 respectively, and the output of microcomputer controller 6 connects described force (forcing) pump 2.Utilize two to be contained in the glass respectively and the outer photosensitive probe of glass, be to detect dust on glass to integrated level for contrast by two photosensitive probe outputs, in order to prevent first photosensitive probe, 7 set of surfaces ashes, can consider the 7 horizontal even inversions of first photosensitive probe.
Microcomputer controller is made up of acquisition module, CPU, time block, Executive Module and TIP, computing module connects described acquisition module, time block, Executive Module and TIP respectively, acquisition module is sent in the output of photosensitive probe, send into CPU after the conversion and calculate contrast, judge that sending clear instruction when needing to clean exports force (forcing) pump 2 to through Executive Module, begin to clean for shower 4 water supply pressurizations.Time block the inside has in advance by the timing and the scavenging period of TIP input, and when predetermined timing arrived, time block was given CPU an instruction, and CPU is clear to the Executive Module beginning that sends instructions; When scavenging period then, time block sends halt instruction to CPU, CPU sends halt instruction to Executive Module.Timing and scavenging period can change by the TIP adjustment.
