Present invention employs air compressor, open air compressor when light rain heavy showers the air with pressure is mixed with by rainfall water by water and gas dual-purpose shower nozzle, to be sprayed by rainfall water by gases at high pressure, thus reach predetermined injection angle degree and atomizing effect, avoid the deficiency of existing rain maker.In addition, by regulating frequency converter, the output pressure of air compressor can be adjusted according to raininess, to reach optimum effect.This device is simple to operate, easy to use, has stronger practical value.
Accompanying drawing explanation
Fig. 1 is the device schematic diagram of the artificially-simulated rainfall atomization of the embodiment of the present invention.
Detailed description of the invention
Hereinafter will be described in detail to embodiments of the invention by reference to the accompanying drawings.It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can be combined mutually.
As shown in Figure 1, the device of the artificially-simulated rainfall atomization of the embodiment of the present invention, comprise: water and gas dual-purpose shower nozzle, high-pressure air duct, air compressor and frequency converter, wherein, the water inlet of described water and gas dual-purpose shower nozzle is connected with the water supply port of rainfall pipeline, the described air inlet of water and gas dual-purpose shower nozzle is connected with one end of high-pressure air duct, and the other end of described high-pressure air duct connects air compressor, and described air compressor is connected with frequency converter.
When the little raininess of needs (raininess is less than 15mm/h) rainfall, open frequency converter and air compressor, air with pressure is delivered to water and gas dual-purpose shower nozzle by high-pressure air duct by air compressor, air with pressure makes to be ejected from water and gas dual-purpose shower nozzle by rainfall water, thus reaches predetermined injection angle degree and atomizing effect.
Installation process is as follows:
First the water inlet end of water and gas dual-purpose shower nozzle is connected with the water supply port of rainfall pipeline, overlay area is needed to adjust the height of rainfall shower nozzle according to the spray angle of shower nozzle and rainfall, the sealing connected will be ensured in the process of snapping, again the air inlet of water and gas dual-purpose shower nozzle is connected with one end of wireway, in connection procedure, ensures air-tightness.Now another section of wireway be connected with air compressor, wireway ensures not occur large bending in the operating process being connected to air compressor, and zero live wire of three power lines of air compressor connects frequency converter UV end, then ground wire is connected the earth.
Need when light rain heavy showers to open frequency converter and the air with pressure is mixed with by rainfall water by water and gas dual-purpose shower nozzle by air compressor, will be sprayed by rainfall water by gases at high pressure, thus reach predetermined injection angle degree and atomizing effect.
The output voltage of frequency converter and the operating frequency of air compressor have corresponding relation, and the air pressure of the operating frequency of air compressor and its output has corresponding relation.According to the relation of output pressure of the raininess demarcated and air compressor, by regulating the voltage of frequency converter, the operating frequency of air compressor can be regulated, and then controls the output pressure of air compressor.
The frequency of air compressor is generally 0HZ to 50HZ, be the voltage 0-10V of frequency converter by the frequency map of air compressor, the frequency of voltage air compressor machine when 0V of frequency converter is 0HZ, and the operating frequency of voltage air compressor machine when 10V of frequency converter is 50HZ.Realize the control to air compressing unit frequency by the voltage adjusting frequency converter, and then control the output pressure of air compressor.
Experimental requirement can demarcate the output pressure (or frequency) of air compressor machine, if the air pressure of air compressor machine crosses the rainwater overatomize that conference makes to fall, form aerosol and can not simulate actual rainfall, needed for can not reaching if too small, concrete how little raininess needs great air compressor machine frequency, repeatedly can demarcate the pressure that the rainfall of the little raininess of difference and air compressor machine coordinate in conjunction with actual demand, simulate the relation curve of rational little raininess and air compressor machine pressure.
In experimentation, carry out the change to air compressor machine frequency by adjustment frequency converter, before rainfall starts, open frequency converter and air compressor; After rainfall terminates after a period of time, close frequency converter and air compressor, prevent precipitation to be back to air compressor place by water and gas dual-purpose shower nozzle.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
