Abstract

The utility model relates to a novel rainwater sample collection is portable device, include: visor, filter screen, rainwater collector, connector, overflow pipe, collection bag. The filter screen is connected with the rainwater collector, and the protective cover is connected with the rainwater collector. The rainwater collector is hollow and is provided with openings at the upper end and the lower end, a flow channel with gradually narrowed width is formed from the upper end to the lower end of the rainwater collector, and the lower end of the rainwater collector is connected with the collecting bag through a connector; the lower end of the overflow pipe is connected with the collection bag through a connector. The advantages are that: the device can reduce the influence of rainfall on the sample collection amount and can ensure that effective samples are collected when the rainfall is small; the interference of non-target samples such as larger particles, winged insects and the like under adverse weather conditions such as strong wind and the like can be reduced; the sealed collection bag and the overflow device can reduce the pollution of the rainwater sample as much as possible; the volume of the sampling device is greatly reduced, and the device is convenient to store and store.

Description

Novel rainwater sample collection is portable device

Technical Field

The utility model relates to an environment science technical field especially relates to a novel rainwater sample collection is portable device.

Background

With the rapid development of economy, the accelerated urbanization process and the remarkable increase of the motor vehicle keeping amount in China, a large amount of pollutants such as sulfur dioxide, nitrogen oxide, industrial smoke dust, volatile organic compounds and the like are discharged into the air. Rainfall scouring plays an important role in removing pollutants in the air, and the pollution status can be better known and the pollutants can be traced by researching the components, the content and the composition characteristics of the pollutants in the rainwater.

Researchers collect rain water samples and perform analytical determinations based on the collected rain water. In the past, a common plastic bucket is sleeved with a clean PP plastic bag and placed in an open place to receive a rainwater sample according to rainfall time. When the rainfall is small, the loss on the PP plastic bag is large, so that the collected water sample is less and the quantitative analysis cannot be sufficiently carried out; especially, rainwater collected when wind power is large often has big foreign matters such as fallen leaves, weeds, small winged insects, influences sample water quality analysis result, and ordinary sampling plastic bucket and PP plastic bag are bulky, difficult to accomodate, easily are polluted, bring inconvenience for rainwater sample collection work.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a novel rainwater sample collection is portable device to solve the aforementioned problem that exists among the prior art. In order to realize the purpose, the utility model discloses a technical scheme as follows:

a novel rainwater sample collection portable device, the device comprising: visor, filter screen, rainwater collector, connector, overflow pipe, collection bag. The filter screen is connected with the rainwater collector, and the protective cover is connected with the rainwater collector. The rainwater collector is hollow and is provided with openings at the upper end and the lower end, a flow channel with gradually narrowed width is formed from the upper end to the lower end of the rainwater collector, and the lower end of the rainwater collector is connected with the collecting bag through a connector; the overflow pipe is hollow inside, and the lower end is connected with the collection bag through a connector.

The utility model has the advantages that: 1. the utility model discloses the influence of reducible rainfall to the sample collection volume can be guaranteed to gather effective sample when the rainfall is less. 2. The utility model discloses can reduce the interference of non-target sample such as great particulate matter, winged insect etc. under the unfavorable weather conditions such as strong wind, airtight collection bag and overflow arrangement can reduce rainwater sample pollution as far as possible. 3. The utility model discloses can reduce sample collection device and pollute, reduce the sampling device volume by a wide margin, the device of being convenient for is accomodate and is deposited.

Drawings

Fig. 1 is a schematic structural diagram of a sample collection device according to an embodiment of the present invention.

In the figure: 1. a protective cover; 2. filtering with a screen; 3. a rainwater collector; 4. a connector; 5. an overflow pipe; 6. and (4) collecting the bags.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the invention, are given by way of illustration only.

As shown in fig. 1, the present embodiment provides a novel portable rainwater sample collecting device, which includes a protective cover 1, a filter screen 2, a rainwater collector 3, a connector 4, an overflow pipe 5, and a collecting bag 6. The protective cover 1 is connected with the rainwater collector 3, and the filter screen 2 is connected with the rainwater collector 3. The rainwater collector 3 is hollow and is provided with openings at the upper end and the lower end, a flow channel with gradually narrowed width is formed from the upper end to the lower end of the rainwater collector, and the lower end of the rainwater collector 3 is connected with a collecting bag 6 through a connector 4; the overflow pipe 5 is hollow and has two open ends, and the lower end of the overflow pipe 5 is connected with the collection bag 6 through the connector 4.

In this embodiment, the use process of the sample collection device is as follows:

open visor 1 before the use, during the use rainwater warp filter screen 2 gets into rainwater collector 3 flows into the lower extreme after rainwater collector 3 collects, gets into and collects bag 6, and the air in the collection bag is discharged through overflow pipe 5. When the rainfall is large and the collecting bag 6 is full of rainwater samples, the redundant rainwater can be discharged through the overflow pipe 5.

In this embodiment, after rainfall or sampling is completed, the connector 3 is removed, and the rainwater sample in the collection bag 6 can be subjected to subsequent operations such as filtration, subpackaging, addition of a sample protective agent, preservation and the like.
