Urban water sample collector

Abstract

The invention discloses an urban water sample collector. The urban water sample collector comprises a collector body, wherein the collector body is a vertical rod-shaped body, and comprises a plurality of water storage cavities, a sliding cavity, a lifting rod, baffles, and a lifting driving device; the water storage cavities are distributed in the height direction of the collector body at equal intervals; a water inlet is arranged at the top of the side wall of each water storage cavity; the sliding cavity is arranged on the collector body located on one side of each water inlet, and can communicate with each water inlet; the lifting rod is arranged in the sliding cavity and can move up and down; the baffles, of which the number is identical to the number of the water storage cavities, are mounted on the lifting rod; the top of the lifting rod is connected with the lifting driving device; when the lifting rod moves up under the action of the lifting driving device, all the water inlets are open, and collected water samples can enter the corresponding water storage cavities through the water inlets; and when the lifting rod moves down, the water inlets can be blocked by the corresponding baffles. The urban water sample collector disclosed by the invention has the advantages that sampling can be carried out on water layers at different depths, so that multiple times of samplingin the traditional art can be avoided, and the sampling efficiency can be greatly improved.

Description

technical field [0001] The invention relates to the technical field of water sample collection equipment, in particular to a water sample collector for urban water bodies. Background technique [0002] Water sample monitoring refers to the monitoring of physical properties, metal compounds, non-metallic inorganic substances, organic compounds, biological monitoring, determination of hydrological and meteorological parameters, and bottom quality monitoring of environmental water bodies. Among them, environmental water bodies include rivers, rivers, lakes, reservoirs, groundwater and water pollution sources; water pollution sources include domestic sewage, hospital sewage and industrial sewage, etc. In the process of water sample testing, the process of water sample collection is very important. [0003] Water sample collection refers to the collection of water samples from environmental water bodies or polluted water bodies, and the basic data of water body pollution can be ...

AI Technical Summary

Problems solved by technology

[0004] However, most of the existing sampling tools can only take water samples from the surface of the water body, and it is difficult to collect water samples from deeper water bodies

Moreover, only one water sample at the sampling point can be taken at the same time. When multiple water samples need to be collected, it is often necessary to collect repeatedly, which is time-consuming and laborious. Therefore, it is necessary to improve its design
