A water quality detection device for detecting pesticide residues in rivers

Abstract

The invention discloses a water quality detection device for detecting pesticide residues of rivers. The water quality detection device comprises a fixed plate, a connecting pipe and a portable detection box, wherein a first fixed seat is fixed on the left side of the upper end of the fixed plate; the upper end of the fixed seat is connected with a rotating shaft; a gear rotating disc is fixed atthe upper end of the rotating shaft; the right side of the gear rotating disc is meshed with an annular rack which is arranged at the upper end of a threaded pipe; a threaded rod is inserted in the threaded pipe in a penetrating manner; the lower end of the connecting pipe is connected with a sampling pipe, and the upper end of the connecting pipe is connected with a connecting hose; an inner connecting pipe is arranged in the portable detection box; a pump is arranged on the inner connecting pipe; the right side of the inner connecting pipe is connected onto a river water filtering device; the right side of the river water filtering device is communicated with a concentration box through a first water pipe; a second water pipe is arranged at the lower end of the concentration box. The water quality detection device for detecting the pesticide residues of the rivers has the advantages that carrying and detection are convenient, efficiency is high and sampling is reasonable, and is suitable for sampling frozen rivers in winter.

Description

technical field [0001] The invention relates to a water quality detection device, in particular to a water quality detection device for detecting pesticide residues in rivers. Background technique [0002] Pesticide residue refers to the general term of pesticide parent, derivatives, metabolites, degradation products and impurities that remain in the environment, organisms and food after pesticide use. Eating food containing a large amount of highly toxic and highly toxic pesticide residues can lead to acute poisoning accidents in humans and animals. Although long-term consumption of agricultural by-products with excessive pesticide residues will not cause acute poisoning, it may cause chronic poisoning in humans and animals, leading to disease, cancer, and even affect the next generation. [0003] In Chinese society, most of the population still lives in rural areas, and the population in rural areas is scattered. A considerable number of rural people drink groundwater fre...

Eating food containing a large amount of highly toxic and highly toxic pesticide residues can lead to acute poisoning accidents in humans and animals

Long-term consumption of agricultural by-products with excessive pesticide residues will not cause acute poisoning, but it may cause chronic poisoning in humans and animals, leading to diseases, inducing cancer, and even affecting the next generation

[0003] In Chinese society, most of the population still lives in rural areas, and the population in rural areas is scattered. A considerable number of rural people drink groundwater freely, and the main source of groundwater is the infiltration of rivers. Currently, river water is sampled and brought back to the experiment. room, inconvenient to use, low detection efficiency, and extremely inconvenient to use in winter
