A kind of rainfall gatherer with primary filter function
Technical field
The present invention relates to a kind of rainfall gatherer with primary filter function, belong to meteorological equipment field.
Background technology
Due to industry and social development, the pollution that factory and building are brought also increases gradually, and in rainy process, a large amount of dust in air and particle to rise and fall back ground along with rainwater one, thus now in city most rainwater all can be mingled with a large amount of solvable or insolubless;
Rain gage is that a kind of meteorologist and hydrologist are used for the instrument (measurement of snowfall then needs to use snow weighing gauge) of the quantity of precipitation measuring somewhere in a period of time; Common are hydrocone type and tipping bucket type two kinds; Traditional rain gage is all the measurement being carried out rainfall amount by the direct collection to rainwater, while rainfall is collected, rainwater can be carried solvable or insolubles and impurity in a large number secretly and enter into udometric device for collecting rain water together, these solvable or insolubless and impurity can badly influence the correct estimation to rain gage rainwater-collecting amount, also in rainwater-collecting bucket, likely there is fouling, corrosion or blocking rainwater U trap simultaneously, damage is caused to whole rain gage;
So in udometric continuous innovation, carry out the dust-proof transformation of sand control to rain gage and become particularly important;
ZL201320176640.9 proposes a kind of sand prevention rain gage, mainly be used in some the soil is porous and to fall and the water yield is large, very easily there is the area of rubble flow, flood, but the dust storm in such kind of area also can be larger, so this practicality mainly improves udometric sand prevention performance, it mainly comprises transparent tube filled with water with a scale, holds rain mouth and bearing, is provided with and holds rain mouth above transparent tube filled with water with a scale, described transparent tube filled with water periphery with a scale is provided with protective cover, described in hold in rain mouth and be provided with anti-sand cover, it realizes the separation to impurity in rainwater mainly through an easy anti-sand cover, and this structure also exists very large defect obviously, silt is after being dissolved by rainwater, because the adhesion of water itself is larger, so the adhesion of silt in adjoint rainwater also insolubles also can increase, if generation heavy showers, and the words that in rainwater, impurity content is higher, be easy to result in blockage to anti-sand cover, rainwater is caused to flow not smooth, a large amount of rainwater directly can fall the outside of steel ladle through anti-sand cover, the accuracy of Rainfall estimation can be had a strong impact on, the silt that particle is less simultaneously can drop in steel ladle through anti-sand cover, bring impact also can to the Measurement accuracy of quantity of precipitation, moreover, to be filtered rainwater by this method of separate mesh and inherently can bring impact to the accuracy of rainwater, especially when rainfall amount is larger, the rainwater handling capacity of separate mesh is more limited, a large amount of rainwater still can from the edge landing of separate mesh, the accuracy that impact is measured.
ZL201320096716.7 it is also proposed a kind of rain gage that can filter rainwater, its main method is in rainwater-collecting bucket, arrange one piece of sponge, this mechanism has better dmp filter compared to the mode arranging filter screen on Sheng rain bucket top layer, but this structure is only suitable for rainfall in a small amount, namely rainfall is less than the water percolating capacity of sponge unit interval, rainfall is once excessive, sponge has little time to ooze out rainwater in time, a large amount of rainwater can be trapped in the sponge top of gathering barrel, then overflow, the Measurement accuracy of quantity of precipitation can be had a strong impact on.
