Background

With the rapid development of industrialization and urbanization, after sewage discharged by industry and sewage discharged by urban life flow into a water body, the content of pollutants in the water body far exceeds the self-cleaning capacity of the water body, so that the chemical property and the physical property of the water body are changed, the characteristics of water are influenced, the health of human beings is harmed, the ecological environment is damaged, and the environmental water quality needs to be monitored by an environmental protection department all the time. In practice, the detection of water quality by the environmental protection department can be roughly divided into on-line real-time detection and off-line detection. The basic operation flow of the off-line detection is that a worker samples the monitored water quality at a specific time and a specific spatial position, the water body is stored in a specific container such as a sample barrel, and then the water body is taken back to a laboratory for analysis and test. In order to improve the accuracy of the test, the water sample in the sample barrel needs to be divided into a plurality of parallel samples to be detected for many times in the same laboratory, or the parallel samples are distributed to different detection units and mechanisms to be compared and detected, so that the sampling modes of the water sample are required to be as consistent as possible; in practice, a water ladle is usually adopted for scooping water from a sample barrel and then pouring the water into different sample dividing bottles, so that after the water scooping action is performed, the difference caused by artificial introduction exists in the water samples in the sample dividing bottles in the sampling stage, the final detection result is influenced to a certain extent, and when the detection result is at a critical value, the error caused in the sample dividing stage is particularly important, so that a parallel water sample splitter needs to be developed, the splitting error is reduced as much as possible, and the consistency of parallel samples is improved.

The labels in the figure are: 1 water sample barrel, 2 parallel rifflers, 21 water inlet hose, 22 elastic expansion parts, 23 water distribution joints, 24 first water outlet hose, 25 second water outlet hose, 3 sampling bottles, 211 flow regulation and control devices, 221 upper valve part, 222 lower valve part, 2211 first one-way valve and 2221 second one-way valve.

Detailed Description

The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments.

As shown in fig. 1, a parallel riffle sampler 2 of water, including inlet hose 21, elastic expansion portion 22, water diversion connector 23 and

outlet hose

24 and 25, inlet hose 21, elastic expansion portion 22, water diversion connector 23 connect gradually, water diversion connector includes two and above delivery ports, and every delivery port is connected one water outlet hose, water diversion connector is any kind of in tee bend, cross, five-way, the six-way, water diversion connector is the stereoplasm plastic tubing, adopt quick-insertion formula sealing connection between water diversion connector and the elastic expansion portion. In fig. 1, a three-way example is shown, and two water outlet pipes, namely a first water outlet hose 24 and a second water outlet hose 25, are connected, so that the sampler can simultaneously collect two parallel water samples. Can conveniently be changed into four-way water distribution joint when three water samples of needs parallel collection, can conveniently be changed into five-way water distribution joint when four water samples of needs parallel collection, can conveniently be changed into six-way water distribution joint when five water samples of needs parallel collection to analogize in this way.
