Abstract
The utility model discloses a high-accuracy rain gauge, which is characterized in that an upper part of a cylinder body (1) is provided with a water storage device (2), an opening of which is provided with a water carrying funnel (3); two sides of the funnel nozzle (4) are provided with water release holes (5); a support seat (6) is disposed in the cylinder body, and is fixedly provided with a horizontal plate (7); a shaft seat (8) on a middle part of the horizontal plate is provided with a shaft (9); the shaft is provided with a tipping bucket (10); and lower parts of two ends of the horizontal plate are respectively provided with a measuring cup (15). The utility model is advantageous in that the defect of the weak accuracy of the rain gauge during the heavy rain can be overcome, the structure and the production technology are simple, and the additional costs are low; the continuous hopping phenomenon can be prevented by adopting the water storage device, additionally disposing the water release holes in the sides of the funnel nozzle, and reducing the caliber of the funnel nozzle; the accuracy of the rainwater measurement is high.
Description
Technical field
The utility model relates to the meteorological equipment field, more precisely a kind of on existing remote measurement tipping bucket type udometer basis improved rainfall device.
Background technology
Udometer is observatory, school's a kind of meteorological equipment commonly used.What use at present is the remote measurement tipping bucket rain gauge, mainly by: raingauge receiver, upper tipping bucket, metering tipping bucket, counting tipping bucket and set screw, dried spring etc. form.Artificial observation and the error that causes hand-manipulated have been avoided in the use of telemetering rain ga(u)ge, have further improved the accuracy of meteorological data and precipitation data.But telemetering rain ga(u)ge also has its weak point: telemetering rain ga(u)ge is normal in measuring the general precipitation process, but in heavy rain season particularly in flood season, and to increase its error just larger along with precipitation intensity.Its reason is due to when quantity of precipitation very large (as the torrential rain in summer), the water speed meeting that upper tipping bucket flows into the metering tipping bucket is very fast, causes measuring tipping bucket in the once inside out process, when water does not flow to end, upper tipping bucket has again water to flow into the metering tipping bucket, makes the metering tipping bucket get back to original position.Flow into like this rainfall of counting tipping bucket just less than 0.1 millimeter, cause the telemetering rain ga(u)ge number greater than actual quantity of precipitation.And the water yield of metering tipping bucket is very fast reaches again suitable rainfall 0.1mm because water does not drain, and again stirs so that phenomenon is jumped by the company of formation.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of structure and production technology simple, and the increase expense is low, the device that the rainwater measuring accuracy is high.
The purpose of this utility model adopts following technical measures to realize: a kind of udometer of pinpoint accuracy, formed by cylindrical shell, tipping bucket, cistern, it is characterized in that: on cylindrical shell top, one cistern is arranged, be equipped with on the cistern mouth and hold hyponome, spout of funnel passes bottom cistern, spout of funnel is shaped with weep hole in the both sides on top, cistern bottom surface, and the aperture of weep hole is greater than the aperture of spout of funnel mouth.Carrier base is housed in cylindrical shell, be fixed with transverse slat on carrier base, on the axle bed at transverse slat middle part, axle is housed, tipping bucket is housed on axle, and a cushion pad is respectively arranged at bottom, tipping bucket two ends, and an end of axle has a connecting link, connect rod end and fix a magnet, respectively there is a limited block at the transverse slat two ends, and below, transverse slat two ends respectively is equipped with a measuring cup, and a tongue tube is arranged in carrier base.
The udometer of the pinpoint accuracy that the utility model provides, its remarkable result: structure and production technology are simple, and the increase expense is low, owing to adopting cistern, spout of funnel side to increase weep hole, reduces the spout of funnel bore, and phenomenon is not jumped by the company of generation, and the rainwater measuring accuracy is high.
