Water quality monitoring and sampling device

Abstract

The invention discloses a water quality monitoring and sampling device, which comprises a main box body, two auxiliary cylinder bodies and a three-fork type steel pipe, solenoids are respectively arranged in the main box body and the two auxiliary cylinder bodies, the solenoids penetrate through the three-fork type steel pipe and an air pipe and are connected with an external storage battery, andthe storage battery is provided with a positive and negative electrode switching switch. Before the device is put into water, the solenoids and the magnet repel each other by switching on the storagebattery; the water inlet ring and the water inlet hole are in a blocked state; after the device reaches a specified sampling position, the solenoids and the magnet attract each other by using the positive and negative electrode switching switch, a water sample enters from the filter screen of the water inlet ring and then enters the main box body through the water inlet hole, and after sampling isfinished, the solenoids and the magnet repel each other by using the positive and negative electrode switching switch, so that the sampling accuracy is ensured. Compared with a plurality of current samplers, the device is low in cost and convenient to use, and is water quality monitoring and sampling equipment which is efficient and accurate in sampling.

Description

technical field [0001] The invention relates to the field of water quality monitoring, in particular to a sampling device for water quality monitoring. Background technique [0002] With the continuous development of industry, human beings will inevitably face the problem of water pollution. Water quality monitoring is particularly important. As the first step in water quality monitoring, sampling for water quality monitoring requires accurate and efficient acquisition of water samples at designated locations. [0003] Among the existing sampling devices, some devices are relatively low in production cost, but during the sampling process, the device is in an open state, and the surface water sample is often mixed in, so the sampling is inaccurate and easily blocked. Although some devices are accurate in sampling, the production cost is too high, and they are not It is convenient for field work. Contents of the invention [0004] The invention provides a low-cost, high-eff...
