Detection device for antibiotics in water environment

Abstract

The invention discloses a device for detecting antibiotics in a water environment, and relates to the field of detection.The device comprises a fixing rod, a plurality of sampling devices are slidably connected to the fixing rod, each sampling device comprises a sampling barrel, and a barrel cover used for sealing the sampling barrel is mounted at the top of each sampling barrel; a water inlet communicated with the interior of the sampling barrel and a ventilation pipe are arranged on the barrel cover, a sealing assembly is arranged at the water inlet, and a switch assembly used for controlling a vacuum pump in the air source device to be turned off is further arranged on the fixing rod. The sealing assembly is arranged on the water inlet of the sampling barrel and is matched with the vacuum pump for use, so that a water sample can be automatically sucked when the water sample needs to be obtained; a floater is arranged in the sampling barrel, so that quantitative sampling is realized; and the water sample obtained from the sampling barrel is not mixed, so that the detection accuracy is greatly improved.

Description

technical field [0001] The invention relates to the field of detection, in particular to a detection device for antibiotics in a water environment. Background technique [0002] In order to understand some water quality parameters in the water environment, it is usually necessary to use professional testing equipment to test the water quality, especially in some reservoirs similar to drinking water, the regular measurement of water quality is particularly important. [0003] Antibiotics are one of the indicators that need to be tested. During testing, a certain amount of testing water samples need to be taken for testing. The existing water samples are usually obtained by using sampling bottles directly in the water area to be tested. This method of obtaining water samples can only obtain part of the water samples at the water surface, and it is difficult to obtain deeper water samples. Since the water samples at different depths are different, the detection results are sing...

AI Technical Summary

Problems solved by technology

This detection method needs to be repeatedly operated when it is necessary to obtain water samples at multiple depths, and it is very inconvenient to operate to control the depth of the water pump entering the water. After a certain depth of water, some water samples will remain in the water pipe. If another depth of water sample is collected at this time, the water pipe will be mixed with water samples of other depths, which will cause deviations in the test results, and in this collection method Some electronic components will be used, so it is necessary to add a waterproof protection structure to these electronic components, and the equipment cost is relatively high
