Description
Technical field
The utility model relates to a kind of hydrographic survey device, and particularly a kind of large capacity quantity of precipitation of measuring quantity of precipitation is measured measuring cup.
Background technology
Along with Hydrological Bureau of Ministry of Water Resources is in test and the management mode of national precipitation station net iterative method " unmanned; someone keeps an eye on ", the rainfall check amount meter of automatic rainfall test equipment is generally developed into the amount meter of the moon or monsoon rain amount by period or daily rainfall, single dose metering increases greatly, rainfall amount, taking mm as unit, even can reach hundreds of mm.Existing legal rainfall measurer is 10mm measuring cup, measuring accuracy is 0.1mm, in the time of amount meter rainfall, amount is counted tens times repeatedly possibly, time-consuming length in amount meter process, and very easily forget, incorrect posting cup time and numerical value, and repeatedly amount is counted the stack that the error producing is each amount meter error, has a great impact measuring meter precision.And adopting existing other non-legal large capacity measurer, requirement that cannot the amount of meeting meter precision, and simple large capacity measurer operating difficulties, manually measure level that timing is difficult to keep measurer and require and affect reading.
The Chinese patent CN202177709U that on March 28th, 2012 is announced, name is called Simple rainfall gauge, this device forms by connecing rain ga(u)ge glass, middle accumulative total measuring cup, total accumulation cup, kickboard, valve: described in it, connect rain ga(u)ge glass, it is upper end open, built-in kickboard, bottom connecting tube also passes into the measuring cup of position lower than self, the valve of connecting in the middle of its pipeline; In the middle of described, accumulative total measuring cup, is upper end closure, built-in kickboard, and bottom connecting tube also passes in the next one accumulative total measuring cup of position lower than self, and the quantity of middle accumulative total measuring cup has one at least; Described total accumulation cup, is upper end closure, built-in kickboard; Described kickboard, is that thickness is not less than 5mm obturator-type polyethylene foam plastics, in each measuring cup, becomes flexible adrift.This device can, by the amount of carrying out meter in the total accumulation cup that repeatedly rainwater of rainfall amount adds up, obtain the quantum of rainfall data in a period of time, but according to the horizontal sectional area of this total accumulation cup, obviously cannot meet accuracy requirement.

As preferably, the lower edge of described each diversion trench is mutually concordant on surface level.
As preferably, the diversion trench on described trough of belt dividing plate is arranged on the position that trough of belt dividing plate and cylindrical shell barrel join.More approaching when the critical localisation of amount of rainfall and sector spill-over, can more intuitively observe rainwater and whether reach edge under diversion trench.
As preferably, the read text scale of described the first sector is taking the max cap. of center measuring cup as initial reading scale, and a rear sector is taking the full-scale reading scale of last sector as initial reading scale.Can be from the direct reading in water surface final position without converting according to sector amount.
As preferably, the barrel height of described cylindrical shell is higher than the height of center measuring cup and dividing plate, and cylindrical shell top is provided with dismountable funnel, and funnel bottom spills a mouthful centering adjustment measuring cup.
As preferably, the below of described cylindrical shell is provided with support, and a top of the trellis is provided with horizontal alignment instrument.
As preferably, described read text scale is taking rainfall amount mm as unit, and volume corresponding to 1mm read text scale is 3.1416 × 10
4mm
3.The unit of rainfall amount is mm, and rainfall observation standard device adopts 200mm internal diameter device mouth to collect rainwater, and according to conversion, 1mm rainfall volume is V
