Abstract

The utility model discloses an automatic recorder for hailstone or rain measuring, composed of four major parts, namely a hailstone-rain collection part, a hailstone-rain filtering separation part, a hailstone-rain conversion part, an auto-recording part, etc. The automatic recorder can separate hailstone and rain thoroughly and automatically record each value, changing the unprogressive aspect that the hailstone measuring is done by hand with a spring scale without a special device at present, widely used in weather observation and scientific experiments.

Description

Automatic recorder for hailstone or rain measuring

A kind of hailstone or rain measuring self-recording device that hail can be separated with rainfall and write down numerical value automatically belongs to meteorological testing apparatus field.

Meteorological observation requires the numerical value of report hail rain landing, but because of no special measurement instrument, in observation, scientific research or its test, can only utilize spring balance that the hail of collecting is made ordinary surveying, and this brings many difficulties just for meteorological research or the daily newspaper that gives.

The purpose of this utility model provides a kind of meteorologic survey instrument of special use, and it can separate hail, rain automatically, and making does not have rain in the hail, do not have hail in the rain, and can automatically both numerical value continuous recordings be got off.

After the purpose of this utility model is achieved in that hail rain is collected, utilize a tilting filter grid that hail rain is separated, rainwater is drained, hail is imported in the special converter, utilize Archimedes's the law of buoyancy that the hail amount is replaced as corresponding conversion liquid measure at this, the numerical value (that is hail value) that will change liquid from register system with traditional float-type is noted then.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is a principle schematic of the present utility model.

The utility model is reached from four most of compositions such as register systems by the collection of hail rain, isolated by filtration, conversion.Wherein, hail rain is collected and is finished in gatherer 1.Gatherer 1 is positioned at the top of shell 20, and its shape should be accepted hail rain, it can be held back again and get together.The embodiment that the utility model provides is connected together the level and smooth kiss of cylindrical vessel that two diameters do not wait, and is up big and down small.For sensitivity and the precision that guarantees to measure, its diameter is suitable big, is about 0.5-1.2 rice.Be provided with a filter grid 2 in the bottom of gatherer 1, it adopts the tinsel of smooth in appearance to make, and according to meteorology hail is given a definition, and interval of grid strip is 3m/m.Hail rain is after this isolated by filtration, and rainwater flow to filter grid 2 bottoms, flows out shell 20 along rain-proof cover 10, and the hail that slides is then imported converter 5 by the hail outlet by guide 3.The inclination angle of filter grid 2 is 45 °-80 °.

Guide 3 is fixed on the sidewall of shell 20.In order to strengthen the separating effect of hail, rain, on the slideway of guide 3, also one-level filter grid 4 can be set again, the rainwater in the hail is further separated.

Converter 5 is cylindrical containers, interior dress conversion liquid 19, and liquid heavily is about the 3-10 kilogram, is injected by the liquid injection pipe 17 that is located at its top.Run-down pipe 21 of straight cutting in the converter 5.One end of run-down pipe 21 immerses in the conversion liquid 19, and the other end stretches out outside the converter 5.When hail falls into conversion liquid 19 when going, the conversion liquid of homogenous quantities can be discharged.Conduit 9 is communicated with run-down pipe 21 and the float chamber in register system 6 get up.Therefore the conversion liquid of discharging enter from register system.

Identical from pen recorder from register system with the rainfall of using at present.It by float chamber 6, write down penholder 14, clock tube 7 and servomotor 8 certainly and form.In float chamber, be provided with float 25, be inserted with float lever 15 above it, fixing self-recording penholder 14 again on float lever 15.The axle of servomotor 8 is gone up cover one sebific duct, and it joins with the lower wall of clock tube 7, makes 7 rotations of clock tube, revolution product parameters selection routinely by both friction force.Self-recording paper is attached on the outer wall of clock tube 7, and when the latter rotates, self-recording penholder 14 will stay record on self-recording paper.

After conversion liquid enters float chamber 6, float 25 can be floated the height that floats relevant with the accumulation conversion liquid measure that flows to (that is relevant) with the hail shooting amount.

Also fixed a U trap 18 on the sidewall of float chamber 6, its effect is when the conversion liquid measure that flows into float chamber 6 transfinites, and can utilize syphonic effect that hydrops is drained into specified altitude.

In order in hail detection, to measure rainfall, can set up gatherer 12 in gatherer 1, gatherer 12 is the same with gatherer 1, and a tilting filter grid 11 is arranged, hail after the separation slips in the gatherer 1 from the sidewall opening of gatherer 12, enters the hail measuring system thereafter.Rainwater then flows into float chambers 22 along conduit 13, there, by float lever 23, self-recording penholder 24, with the rainfall records of values on the self-recording paper on the clock tube 7.Its principle of work is identical from register system with hail detection with structure, and only the diameter of gatherer 12 is more smaller, and concrete numerical value product parameters is routinely selected.

Conversion liquid 19 can adopt water, also can adopt other low prices, the liquid that is easy to convert.

During operation, at first in converter 5, inject conversion liquid, till siphon once; Open motor 8, record the time, begin to measure; When hail detection stops, shutdown immediately, and record the time and take off self-recording paper, observation finishes.Then, analyze observational error, revise data, obtain the meteorologic parameter of this time hail rain landing.

The utility model is simple in structure, and is easy to operate, the accuracy of observation height, and it has solved the backward situation that present hail detection does not have instrumentation, uses the spring balance hand dipping, can be widely used in meteorological observation and the scientific experimentation and go.
