Problems solved by technology

[0004] The purpose of the present invention is to provide a sampling detection device and detection method for river water pollution, which solves the problem that the existing water body in the river will be confused when sampling and detection of the river, which will cause substances in different areas to mix with each other, resulting in sample detection. The test results cannot accurately reflect the problem of the degree of river pollution

Embodiment 1

[0037] Such as Figure 1 to Figure 4 As shown, the present invention provides a sampling detection device for river water pollution, including a support mechanism 1, a fluid follower mechanism 2, a lift mechanism 3 and a spacing sampling mechanism 4, and the fluid follower mechanism 2 is movably connected to the lift mechanism 3, the lifting mechanism 3 is fixed on the support mechanism 1, and the spacing type sampling mechanism 4 is arranged on the fluid follower mechanism 2;

[0038]The supporting mechanism 1 is used to suspend the fluid follower 2 on the water surface, and the fluid follower 2 is immersed in the target depth of the water body under the lowering action of the lifting mechanism 3, and the fluid follower 2 can swing following the direction of the water flow;

[0039] The spacing type sampling mechanism 4 includes a detachable sampling assembly 401 arranged on the fluid follower mechanism 2 and a plurality of sampling cylinders 402 arranged horizontally on the ...

Embodiment 2

[0074] The present invention also provides a detection method for a sampling detection device for river water pollution, comprising the steps of,

[0075] S100, setting the supporting mechanism on the river bank, inserting the sampling component into the linear groove, and fixing the position of the sampling component by the fixing component;

[0076] S200, start the one-way motion component to transport the fluid follower mechanism, the lifting mechanism and the spacing sampling mechanism to a predetermined position on the river surface, and then start the lifting mechanism to drive the fluid follower mechanism and the spacing sampling mechanism to immerse in the river;

[0077] S300, after the spacing sampling mechanism is left in the river water for a period of time, start the sampling structure and close both ends of the sampling cylinder to complete sampling, drive the spacing sampling mechanism to reset through the lifting mechanism and one-way movement component, and tak...

Abstract

The invention discloses a sampling detection device and method for river water pollution, the sampling detection device comprises a support mechanism, a fluid follow-up mechanism, a lifting mechanism and a spacing type sampling mechanism, the fluid follow-up mechanism is movably connected to one end of the lifting mechanism, the lifting mechanism is fixed on the support mechanism, and the spacing type sampling mechanism is fixed on the fluid follow-up mechanism. The spacing type sampling mechanism comprises a sampling assembly detachably arranged on the fluid follow-up mechanism and a plurality of sampling barrels arranged on the sampling assembly in the horizontal direction, and the fluid follow-up mechanism and the spacing type sampling mechanism can swing in the sampling target water area along with the water flow direction; compared with a sampling mode fixed in the target water area, the degree of disorder of the water sample in the sampling water area caused by water flow shearing or impacting the sampling barrel is reduced, so that the detection accuracy of the target water sample is improved, and the obtained detection result can better reflect the water body condition of the target water area; and water samples at different depths of a target water area can be obtained at the same time, and sampling is efficient.

Description

technical field [0001] The invention relates to the technical field of river water sampling, in particular to a sampling detection device and detection method for river water pollution. Background technique [0002] River pollution refers to the direct or indirect introduction of substances or energy into the river environment by human activities, causing harmful effects such as damaging river biological resources, damaging river water and river environmental quality, and endangering human health. It is a type of water pollution. The degree changes with time, and the diffusion is fast, and the pollution has a great impact. Therefore, sampling and testing of river water is required to monitor river pollution problems. [0003] Currently, when sampling and testing river water, the sampling container is generally directly thrown or inserted into the water for sampling, and the river water samples in the corresponding area can be intercepted for subsequent testing to achieve eff...
