Description

A groundwater sampler

technical field

The utility model relates to a water sampler, in particular to a groundwater sampler.

Background technique

With the continuous development of my country's modern industry and the excessive collection of groundwater in my country, the quality and quantity of groundwater in most areas have been seriously affected, and groundwater pollution will have different effects on human health, agricultural production, and ecological effects. Therefore, it is imperative to monitor the water quality of groundwater. At present, there are various groundwater samplers on the market. Electric pumps or airbag pumps are commonly used for sampling. The collected water samples have more impurities and require subsequent filtration treatment, which undoubtedly increases the experiment time.

Utility model content

The technical problem to be solved by the utility model is to provide a groundwater sampler for the deficiency of the background technology, which effectively solves the problem of more impurities in the water sample during the sampling process and provides convenience for subsequent detection.

The utility model adopts the following technical solutions for solving the above-mentioned technical problems:

A groundwater sampler comprises a connecting rod and a water container, the water container includes an upper funnel and a mouth at the bottom of the funnel, the connecting rod penetrates into the funnel and its bottom end is screwed to the mouth; the funnel is provided with There is a cover, and the cover includes an inner ring and an outer ring, the inner ring and the outer ring are connected by a strut, the inner ring is sleeved on the connecting rod, and the outer ring is mated and connected to the mouth of the funnel. The bottom of the lid is covered with filter paper.

Further, the connecting rod is composed of several short rods connected to each other.

Further, adjacent short rods are connected by threads.

Further, the middle part of the inner ring is provided with a raised portion extending upwards, and the raised portion is threadedly connected with the connecting rod.

Further, the area of the filter paper is larger than the area of the funnel mouth, and the cover presses the filter paper to seal the funnel mouth.

Compared with the prior art by adopting the above technical scheme, the utility model has the following technical effects:

The groundwater sampler of the present utility model can be made of plastic in all materials, and is small in weight, easy to carry and store, the sampling process is simple and quick, and easy to master. The filter paper funnel can filter large particles of impurities in time, and the water container is convenient for washing, which effectively solves the problems of inconvenient collection due to the excessive buried depth of groundwater, easy dirty hands and laborious problems during the sampling process, reducing the detection of groundwater quality error. Since there is no electric drive, the cost is low and the environment is environmentally friendly.

Detailed ways

Below in conjunction with accompanying drawing, the technical scheme of the utility model is described in further detail:

A groundwater sampler, as shown in Figures 1 and 2, includes a connecting rod 1 and a water container 2, the water container 2 includes an upper funnel 21 and a mouth 22 at the bottom of the funnel 21, and the connecting rod 1 penetrates into the funnel 21 and its bottom end is threadedly connected with the mouth 22; the funnel 21 is provided with a cover 3, the cover 3 includes an inner ring 31 and an outer ring 32, and the inner ring 31 and the outer ring 32 are connected by a support The rod 33 is connected, the inner ring 31 is sleeved on the connecting rod 1, the outer ring 32 is matched and connected to the mouth of the funnel 21, and the bottom of the cover 3 is covered with filter paper 4.

The connecting rod 1 is composed of several short rods 11 connected to each other. The adjacent short rods 11 are connected by threads. The middle part of the inner ring 31 is provided with a protruding part 311 extending upwards, and the protruding part 311 is threadedly connected with the connecting rod 1 . The area of the filter paper 4 is greater than that of the funnel 21 mouth, and the cover 3 presses the filter paper 4 to seal the funnel 21 mouth.

Specific implementation instructions:

When the soil drill is used to drill to the groundwater surface at the experimental site, since the short rod 11 is a fixed length rod, the connecting rod 1 can be used to measure the buried depth of the groundwater, wait for three to five minutes, and when the groundwater seeps to a certain height, sample the groundwater. The device is placed below the surface of the groundwater, and can be taken out when the water container 2 is full of groundwater, and the groundwater is filtered with a funnel 21 with filter paper 4, and collected in a test tube to obtain a filtered water sample.
