Water droplet similar in partial size, to realize the natural landing of raindrop；It sprays water in the spray head 306 to 302 direction of rain-proof cloth
Meanwhile thering is sub-fraction water to be attached on the drop rain sieve 303, the part water also vertical drop under gravity, thus
Realize the simulation process of natural precipitation.
By above each embodiment it is found that Portable artificial rainfall simulation device of the invention, existing beneficial effect
It is:
(1) Portable artificial rainfall simulation device of the present invention, sets gradually rain-proof cloth and drop at the top of bracket
Rain sieve, and spray head is gone out into water surface face rain-proof cloth direction, the water for spraying spray head is trickled down on rain-proof cloth, makes it in itself weight
Power acts on lower vertical drop, through drop rain sieve to be formed with water droplet similar in natural Raindrop diameter, to realize the mould of natural precipitation
Quasi- process.
(2) Portable artificial rainfall simulation device of the present invention is controlled in water-feed by pressure-regulating valve door
Pressure, and then the unit time amount of water sprayed for the spray head being connected with water-feed is controlled, to can realize that the simulation of sinking raininess is real
It tests, single simulation precipitation experiment can be completed by a small amount of water, avoid the waste of water resource, make field trial no longer by water source
Ground limitation.
(3) Portable artificial rainfall simulation device of the present invention drives spray head in simulation test by driving equipment
Reciprocating motion at the uniform velocity is done in area, so that the water for spraying spray head can be uniformly sprayed on rain-proof cloth with maximum area, thus
The uniformity of simulated rainfall is further increased, so that the data accuracy of simulated rainfall experiment is higher.
Although some specific embodiments of the invention are described in detail by example, the skill of this field
Art personnel it should be understood that example above merely to being illustrated, the range being not intended to be limiting of the invention.The skill of this field
