This shallow water negative pressure water sampler utilizes the aspiration pump to take out into the negative pressure with the sampling bottle to in letting the sample flow into the sampling bottle naturally, can avoid artificially taking a sample to cause the pollution to the sample, convenient operation is swift, and sampling efficiency is high, can adapt to the sampling environment of various complicated scene such as monitoring well deep water is shallow.

Description

Shallow water negative pressure water sampler

Technical Field

The utility model relates to a water sampling technical field specifically is a shallow water negative pressure water sampler.

Background

In environmental monitoring, water quality sampling is a very important link. Whether the sample collection is representative, typical and time-efficient is directly related to the final monitoring result. Then in the actual sampling process, the situation that water samples cannot be taken due to too shallow water level in the monitoring well is often encountered, the water quality sampler on the market at present mainly samples through pressure difference, the water samples cannot be taken due to too shallow water level, or impurities at the bottom are brought up, so that field sampling is very difficult.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a shallow water negative pressure water sampler to solve the problem that proposes among 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 shallow water negative pressure water sampler, includes the aspiration pump, prevents down suction bottle and sampling bottle, the aspiration pump, prevent down suction bottle and sampling bottle loop through the connecting pipe and connect, still the intercommunication has the inlet tube on the sampling bottle, and the sampling bottle upper end is connected with the stay cord.

As a further aspect of the present invention: the pull rope is made of nylon.

As a further aspect of the present invention: the water inlet pipe is provided with a flow clamp.

Compared with the prior art, the beneficial effects of the utility model are that:

this shallow water negative pressure water sampler utilizes the aspiration pump to take out into the negative pressure with the sampling bottle to in letting the sample flow into the sampling bottle naturally, can avoid artificially taking a sample to cause the pollution to the sample, convenient operation is swift, and sampling efficiency is high, can adapt to the sampling environment of various complicated scene such as monitoring well deep water is shallow.

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 efforts belong to the protection scope of the present invention.

It should be noted that, if there is a directional indication (such as up, down, left, right, front, and back) in the embodiment of the present invention, it is only used to explain the relative position relationship between the components, the motion situation, etc. in a certain specific posture, and if the specific posture is changed, the directional indication is changed accordingly.

In addition, if a description of "first", "second", etc. is referred to in the present invention, it is used for descriptive purposes only and not to be construed as indicating or implying relative importance or implicit to the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions in the embodiments may be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should not be considered to exist, and is not within the protection scope of the present invention.

Example 1

Referring to fig. 1, the shallow water negative pressure water sampler comprises an air pump 1, a reverse suction prevention bottle 2 and a sampling bottle 3, wherein the air pump 1, the reverse suction prevention bottle 2 and the sampling bottle 3 are sequentially connected through a connecting pipe 4, the sampling bottle 3 is also communicated with a water inlet pipe 7, and the upper end of the sampling bottle 3 is connected with a pull rope 6;

the specific material of the pull rope 6 is not limited, and in this embodiment, preferably, the pull rope 6 is made of nylon;

in order to control the sampling flow conveniently, the water inlet pipe 7 is provided with the flow clamp 5, and the opening of the channel of the water inlet pipe 7 is controlled through the flow clamp 5, so that the water inlet flow is adjusted, and the operation is convenient and rapid.

The working principle of the embodiment is as follows:

when sampling is carried out on site, the sampling bottle 3, the suck-back prevention bottle 2 and the air pump 1 are sequentially connected through the connecting pipe 4, the sampling bottle 3 is placed to a specified depth through the pull rope 6, the air pump 1 is used for pumping the sampling bottle 3 into negative pressure, and pressure difference is formed between the negative pressure and the outside, so that a water sample naturally flows into the sampling bottle 3 through the water inlet pipe 7; after the water sample is fully collected, water flow can continuously flow to the air pump 1 through the connecting pipe 4, the anti-suck-back bottle 2 can effectively prevent the water flow from directly entering the air pump 1, and sufficient reaction time is provided for operators; after the collection is finished, only the sampling bottle 3 needs to be taken out of the water surface, and the sealing cover is replaced, so that the sample collection can be completed.

This shallow water negative pressure water sampler utilizes aspiration pump 1 to take out into the negative pressure with sampling bottle 3 to in letting the sample flow into sampling bottle 3 naturally, can avoid artificially taking a sample to cause the pollution to the sample, convenient operation is swift, and sampling efficiency is high, can adapt to the sampling environment of various complicated scene such as monitoring well deep water is shallow.
