Description

Rain gauge sand prevention dust hood

Technical field

The utility model is related to the rain gauge monitored for rainfall, rain gauge perfect in shape and function, more particularly to a kind of rainfall Device sand prevention dust hood.

Background technology

Rain gauge is the special implement for collecting precipitation, and by matched precipitation gauge, for determining with milli Rice is the precipitation of unit.It is used for suitable for meteorological observatory's (station), hydrometric station, environmental protection, flood control and drainage and agriculture, Lin Deng relevant departments Measure precipitation.Rain gauge is traditional product, as shown in figure 3, the upper diameter 200mm of rain gauge, it is allowed to 0~0.6mm of error, In general, the stack shell of rain gauge is molded using stainless steel plate soldering.

With social development, requirement of the society to rainfall monitoring is improved constantly, and precipitation station is continuously increased, and increases precipitation station newly big Many to be monitored using rain gauge or automatic monitoring rain gauge, automatic monitoring rain gauge much keeps an eye on unattended using someone Working method, the operation of automatic monitoring rain gauge is carried out automatically by automatic monitoring rain gauge completely, in this case, if rain Measuring device mouthful is blocked by debris such as sand and dust, can block rainwater and flow into the rainfall bucket of rain gauge or the tipping bucket of automatic monitoring rain gauge, make Rain gauge or automatic monitoring rain gauge can not normally be run, it is impossible to accurately obtain rainfall data.

The content of the invention

In view of the above-mentioned drawbacks of the prior art or not enough, the purpose of this utility model is that there is provided a kind of rain gauge Sand prevention dust hood.

In order to realize above-mentioned task, the utility model uses following technical solution：

A kind of rain gauge sand prevention dust hood, it is characterised in that including a cover body being connected with rain gauge, cover body passes through even Connect ring and be placed with hyponome, crossing hyponome center provided with resistance sand and dust net, be also associated with holding rain mouthful above cover body.

Other features of the present utility model are：

The connection ring, resistance sand and dust net, hyponome, cover body excessively are made using stainless steel material.

The internal diameter of the connection ring is 203mm, and external diameter is 210mm.

The stainless steel wire that the resistance sand and dust net is less than 0.5mm using diameter makes, a diameter of 2.5mm, and the superiors are stainless Steel wire is covered, and screen distance is 1mm.

The hyponome of crossing is taper platform, and the maximum inner diameter of the taper platform is 200mm, and minimum diameter is 2.5mm.

The cover body is ring-shaped cylinder, and internal diameter is 200mm.

The rain mouthful that holds is in interior straight outer oblique knife-edge, 40 °~45 ° of cutting edge acute angle.

The rain mouthful that holds is made of copper or aluminium alloy, internal diameter position 200mm.

Rain gauge sand prevention dust hood of the present utility model, can be placed in and be adapted to current someone and keep an eye on unattended rainfall Above the rain gauge stood, it is connected with rain gauge rainwater-collecting mouthful；Sand and dust, debris are prevented to pass through entrance by rain gauge sand prevention dust hood Into inside rain gauge, it is ensured that rain gauge is normally run.Compared with prior art, the beneficial effect brought is：

Rain gauge sand prevention dust hood of the present utility model is disposed on rain gauge, it is possible to prevente effectively from the debris such as sand and dust blocks rain Measuring device rainwater-collecting mouthful, it is to avoid because of sand and dust, debris obstruction rain gauge rainwater-collecting mouthful, influence rainfall gauge normal work, improve rain Measure accuracy of measurement, it is ensured that measure different periods rainfall.Because most of part is made using stainless steel material, surface is smooth to be promoted Rainfall is fallen rapidly, do not stay in rain gauge sand prevention dust hood surface.Solve because of the lance that personnel are reduced, precipitation station increase is brought Shield, the watchman of precipitation station need to only require according to General Maintenance, inspect periodically rain gauge sand prevention dust hood, periodic cleaning, so that it may Ensure that rain gauge, automatic monitoring rain gauge are normally run for a long time, mitigate working strength, improve operating efficiency, reduction is nursed into This.
