Abstract

The utility model discloses an anti-blocking rain measuring cylinder for a meteorological area station, which comprises a cylinder body, wherein a convex ring is fixedly connected at the inner bottom of the cylinder body, a filter screen is arranged on the upper surface of the convex ring, a second filter disc is arranged on the upper surface of the filter screen, a plurality of second filter holes are arranged on the surface of the second filter disc, and a sleeve is sleeved outside the cylinder body, the utility model discloses a plurality of filter components are arranged, because the density of the filter screen is far greater than that of the second filter holes on the second filter disc, and the density of the second filter holes on the second filter disc is far greater than that of the first filter holes on the first filter disc, so that the first filter holes and the second filter holes can both block a part of large sundries, but the sundries with smaller volume are directly filtered by the filter screen, the rainwater can reduce the speed of continuous downflow flow after falling into the second filter disc, thereby effectively avoiding the filter screen from being blocked by the tiny sundries, and, and the cleaning of the components is also convenient, the cleaning of impurities is easier, and the applicability is higher.

Description

Anti-blocking rain measuring cylinder for meteorological area station

Technical Field

The utility model relates to a meteorological detection technical field specifically is a prevent stifled rain graduated flask that meteorological area station was used.

Background

The rain gauge is a special appliance for collecting rainfall, is used for measuring the rainfall in millimeters, and is suitable for measuring the rainfall in weather stations (stations), hydrological stations, environmental protection, flood prevention and drainage, agriculture, forestry and other related departments.

However, the rain gauge used in the existing meteorological area station is easy to block due to the fact that the filter screen holes in the rain gauge are large, dust, bugs and other sundries easily fall off, and the sundries are easy to block once accumulated on the filter screen too much or too fast, so that the accuracy of calculating the precipitation is affected, manual regular cleaning is needed, and the workload of business personnel is increased.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a weather region station is used prevents stifled rain graduated flask to solve the problem that provides in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a weather region station is used prevents stifled rain graduated flask, comprises a cylindrical shel, the interior bottom fixedly connected with bulge loop of barrel, the filter screen has been placed to the upper surface of bulge loop, No. two cassette filters have been placed to the upper surface of filter screen, No. two cassette's surface is equipped with a plurality of No. two filtration pores, the outside cover of barrel is equipped with the sleeve, a telescopic inside fixedly connected with cassette, the surface of a cassette is equipped with a plurality of filtration pores, telescopic top threaded connection has sealed lid.

As an optimal technical scheme of the utility model, a cassette is the trapezoidal form of falling, just the middle part of a cassette is equipped with the through-hole.

As an optimal technical scheme of the utility model, No. two filter discs are the heliciform, just the middle part of No. two filter discs is provided with the perforation from last to down.

As an optimal technical scheme of the utility model, the density of filter screen is greater than the density of No. two filtration pores on No. two filters, just the density of No. two filtration pores on No. two filters is greater than the density of a filtration pore on a filter.

As an optimized technical scheme of the utility model, the upper surface of No. two cassette highly is greater than the lower surface of a cassette to telescopic bottom surface height to the top surface of barrel.

Compared with the prior art, the beneficial effects of the utility model are that: this prevent stifled rain graduated flask that meteorological area is used at station, through setting up a plurality of filtering component, because the density of filter screen is far greater than the density of No. two filtration pores on No. two filters, and the density of No. two filtration pores on No. two filters is far greater than the density of a filtration pore on No. one filter, so a filtration pore all can block partly big debris with No. two filtration pores, but the less debris of volume is direct to be filtered by the filter screen, so the cleanliness factor of sample water has been improved, No. two filters are the heliciform simultaneously, the speed that the rainwater continues the downcast again after falling into No. two filters will reduce, thereby effectually avoided the filter screen to be blockked up by tiny debris, whole water purification degree is higher, and it is also convenient to wash the component, it is also lighter to clear up impurity, the suitability is higher.

In the figure: 1. a barrel; 2. a second filter disc; 3. a second filter hole; 4. a sleeve; 5. a first filter disc; 6. a first filter hole; 7. a sealing cover; 8. a convex ring; 9. and (5) filtering by using a filter screen.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, the present invention provides a technical solution: the utility model provides a weather region station is used prevents stifled rain graduated flask, includes barrel 1, barrel 1's interior bottom fixedly connected with bulge loop 8, filter screen 9 has been placed to the upper surface of bulge loop 8, No. two cassette 2 have been placed to the upper surface of filter screen 9, No. two cassette 2's surface is equipped with a plurality of No. two filtration pores 3, barrel 1's outside cover is equipped with sleeve 4, No. one cassette 5 of the inside fixedly connected with of sleeve 4, No. one cassette 5's surface is equipped with a plurality of filtration pores 6, sleeve 4's top threaded connection has sealed lid 7.

Wherein, a cassette 5 is the shape of falling the trapezoid, and the middle part of a cassette 5 is equipped with the through-hole, makes things convenient for the rainwater can be along the inclined plane through a filtration pore 6 and the next filter unit of through-hole flow direction on, plays the prefiltration effect, avoids simultaneously to remain in the corner of a cassette 5 with the impurity of aquatic.

Wherein, No. two filter discs 2 are the heliciform, and the middle part of No. two filter discs 2 is provided with the perforation from last to down, further strengthens the filter effect, improves the clean degree of rainwater.

Wherein, the density of filter screen 9 is greater than the density of No. two filtration pore 3 on No. two filter discs 2, and the density of No. two filtration pore 3 on No. two filter discs 2 is greater than the density of a filtration pore 6 on No. one filter disc 5, through setting up the filter component of different density sizes, ensures that the rainwater purifies fully.
