Description

TECHNICAL FIELD

[0001] The utility model relates to water environment pollution technical field especially relates to a sampling device for water environment pollution treatment. BACKGROUND

[0002] Industrial wastewater discharge, domestic sewage discharge, agricultural non-point source pollution and the like may result in water environment pollution, and the consequences of water environment pollution are very serious, which not only affects human health and life quality, but also has far-reaching influence on ecological environment and economic development.

[0003] When investigating pollution sources, the water quality sampling device can be used to collect water samples from water bodies near suspected pollution sources to analyze the composition, concentration and discharge law of the pollution sources.

[0004] The water quality sampling device includes but is not limited to a sampling container, a sealing cover and a connecting component (such as a rope), the rope is tied to one end of the sampling container, and then the sampling container is thrown into water, when the sampling container sinks into water, the sealing cover is opened, and the sampling container collects water samples.

[0005] The current water quality sampling device does not have a filtering function, therefore, when collecting water samples, the water quality sampling device may collect impurities such as suspended solids, colloids and microorganisms in water, the existence of these impurities may affect the representativeness of water samples, so that the analysis results cannot accurately reflect the true water quality condition of water bodies, therefore, after the water quality sampling device collects impurities such as suspended solids, colloids and microorganisms, manual separation of suspended solids and the like is required, and the process of manually separating impurities usually needs to consume a large amount of time and energy. TECHNICAL SOLUTION

[0006] In view of the problems existing in the prior art, the utility model provides a sampling device for water environment pollution treatment, which can effectively solve the problems existing in the prior art.

[0007] The technical scheme of the utility model is as follows:

[0008] According to one aspect of the utility model, a sealing cover, a sleeve, a first filter, a second filter and a sampling container are sequentially arranged from top to bottom, and the sealing cover is detachably covered on the sleeve at one end;

[0009] The first filter and the second filter are both used for filtering impurities, and the first filter and the second filter are arranged at intervals between the sleeve and the sampling container, one end of the first filter is detachably inserted into the sleeve, the other end is detachably inserted into the second filter, and one end of the second filter is detachably inserted into the sampling container; the filter hole of the first filter is larger than that of the second filter; the sealing cover, the sleeve, the first filter, the second filter and the sampling container are connected in communication.

[0010] Further, the first filter upper end extends towards the sleeve and is provided with a first fixing cylinder, which is screwed with the sleeve.

[0011] Further, the first filter lower end extends towards the second filter and is provided with a second fixing cylinder, and the second filter upper end extends towards the first filter and is provided with a fixing base, which is screwed with the second fixing cylinder.

[0012] Further, the second filter lower end extends towards the sampling container and is provided with a third fixing cylinder, which is screwed with the sampling container.

[0013] Further, the sealing cover is screwed with the sleeve.

[0014] Further, the first filter outer lateral wall is provided with a first convex edge, the upper end surface of which is abutted with the sleeve, and the lower end surface of which is abutted with the second filter, and the second filter outer lateral wall is provided with a second convex edge, the lower end surface of which is abutted with the sampling container.

[0015] Further, the first filter is provided with a plurality of first filter holes, which are rectangular.

[0016] Further, the second filter is provided with a plurality of second filter holes, which are circular.

[0017] Further, the sampling container lower end is provided with a water outlet, which is equipped with a valve for opening and closing water flow, and is further provided with a connecting head for connecting a hose.

[0018] Further, it further comprises a lock and a rope, one end of the lock is fixedly arranged on the sealing cover, and the other end is fixedly arranged with the rope.

[0019] Compared with the prior art, the technical scheme has the beneficial effects that:

[0020] First, the first filter element can quickly filter out large particles in the water, such as plant debris, weeds, floating plastic fragments, etc., due to its larger first filter hole, and the second filter element is responsible for further filtering out small impurities in the water that still exist after passing through the first filter element, such as silt, small stones, etc. Through hierarchical filtering, the water quality sampling device can remove impurities while retaining the original characteristics and components of the water body as much as possible, which helps to ensure that the water sample can truly reflect the water quality of the monitored water body, improving the accuracy and reliability of the analysis. After collecting the water sample, the traditional water quality sampling device needs to be manually separated from the suspended solids and other impurities. This process not only consumes time and effort, but also introduces errors. By setting the first filter element and the second filter element, the amount of manual separation can be greatly reduced, improving work efficiency. The hierarchical filtering design makes the operation of the water quality sampler more convenient, and the operator only needs to put the sampler into the water and wait for the water sample to pass through the first filter element and the second filter element.

[0021] Second, the sealing cover, sleeve, first filter element, second filter element and sampling container are connected by threads, so that the device can be easily disassembled and assembled. When the filtered impurities need to be cleaned, the first filter element and the second filter element can be quickly disassembled.

[0022] Third, the water outlet of the current sampling container is usually equipped with a hose, and the hose is clamped with a clamp. When the water sample in the sampling container needs to be taken out, the clamp is loosened. Using the clamp to clamp the hose may cause damage to the hose, such as clamp marks and deformation. Long-term use of the hose may cause damage, resulting in water leakage. The valve can accurately control the opening and closing degree of the water outlet, thereby adjusting the flow. The use of the valve can simplify the sampling operation process. The valve has good sealing performance in the closed state, which can prevent accidental leakage of the water sample during sampling.
