Description

Simple multilayer water sample collection device

Technical Field

The utility model relates to the technical field of water environment monitoring tools, in particular to a simple multilayer water sample collecting device.

Background

In the water quality monitoring, except for a few indexes, the indexes can be measured on site through a portable instrument, most of water quality indexes still need to bring collected water samples back to a laboratory for analysis and evaluation, and therefore water sample collection is the premise of subsequent water quality analysis. And the existing convenient instrument can not collect the water in the middle layer or the bottom layer.

When outdoor water sample is collected, a water sampler is mainly placed into water on a ship or in the middle of a bridge to collect a water sample at a specified depth, then the water surface is lifted out, water is placed into a container and is taken back to a laboratory for analysis, so that the speed is slow and labor is wasted, and when no sampling ship or no bridge exists, the problem that soil is soft and moist, people cannot approach the container due to the fact that the water sample cannot be collected due to the fact that part of river and lake shoreside is soft and moist. Therefore, the improvement is made, and the simple water sample collecting device is provided.

Detailed Description

The present invention will be explained in detail below with reference to the schematic drawings.

The utility model discloses a simple multilayer water sample collecting device, which comprises a long rod 1, winding turntables (2,3), ropes (4,5) and a water collector 18, and is characterized in that: stock 1 and water intaking ware 18 are the cylinder shape, connect through cotton rope 4, stock 1 rear end is handle 7, and foremost is equipped with lead ring 6, and upper and lower both sides are equipped with little wire loop 8, wire reel (2,3) are fixed in stock 1 rear end, contain fixed line endpoint 19, handle 16 and pivot 15 for the fixed and stretch of cotton rope (4,5), two cotton ropes (4,5) are connected water intaking ware 18 and piston 10 respectively for the fixed and control piston 10 activity of water intaking ware 18, water intaking ware 18 contains lid 12, piston 10 and drain valve 9, is used for the collection and the collection of water sample, plumb 11 links to each other with piston 10 for the buoyancy that the water that offsets the production avoids water to gush into water intaking ware 18.

Principle of operation

Before using, the cotton rope 5 of winding of upper end wire reel 3 is released loosely, when preventing that drainer 18 from transferring the collection water sample, piston 10 is opened and is intake, when getting the top water, slowly rotate grab handle 16 through downside wire reel 2 and release cotton rope 4, make the slow income aquatic of getting water ware 18, after water ware lid 12 soaks under the water surface, slowly tighten up upper end wire reel 3, make the piston 10 that weighs down plumb 11 slowly open, the water sample flows into water ware 18, then loosen upper end wire reel 3, make piston 10 seal the water inlet under plumb 11 effect, slowly tighten up downside wire reel 2, take out water ware 18, collect the water sample through twisting drain valve 9, and then reach the mesh of field collection, middle level and bottom water collection principle are unanimous.
