A water sample collection device capable of multiple sampling

Abstract

The invention discloses a water sample collection device with a repeated sampling function. The water sample collection device comprises a tank. A first partition plate and a second partition plate are arranged in the tank, the tank is divided into a first chamber, a second chamber and a third chamber by the first partition plate and the second partition plate, a driving mechanism and a movable plate are arranged in the first chamber, a second gas guide tube, a third gas guide tube and a plurality of first gas guide tubes are arranged in the second chamber, a collection bottle is arranged in the third chamber, sample chambers are arranged in the collection bottle, a first through hole is formed in the side, which corresponds to the corresponding first gas guide tube, of each sample chamber, a second through hole is formed in a side of the bottom of each sample chamber, water outlet tubes are arranged on the outer side of the tank, a third through hole is formed in the side, which is opposite to the corresponding first through hole, of each sample chamber, and water suction tubes are arranged on the outer side of the tank. The water sample collection device has the advantages that the water sample collection device is provided with the water outlet tubes, water body samples collected in the sample chambers in the collection bottle can be drained into test tubes from the water outlet tubes, accordingly, water bodies at different locations of the same water area can be conveniently collected again, and the water sample collection device can be conveniently and quickly operatedand is high in efficiency.

Description

Technical field [0001] The invention relates to the technical field of environmental detection, in particular to a water sample collection device capable of multiple sampling. Background technique [0002] At present, with the continuous development of human science and technology, people’s damage to the environment is becoming more and more serious. The damage to water resources is especially serious. In order to effectively control the water in a certain water area, it is necessary to Water samples are collected from the water, and the contaminated water sources are treated by detecting the collected water samples. There are many types of water sample collection devices in the prior art, but most of them have low sampling efficiency and cannot collect samples of different depths in the same water area at the same time. Water samples, the water sample collection device in the announcement number CN206710137U, although it can collect water samples of different depths in the same ...

[0002] At present, with the continuous development of human science and technology, people's damage to the environment is becoming more and more serious, and the damage to water resources is particularly serious. In order to effectively control the water in a certain water area, it is necessary to The collected water samples are used to collect water samples, and the polluted water sources are treated by detecting the collected water samples. There are many kinds of water sample collection devices in the prior art, but most of them have low sampling efficiency and cannot simultaneously collect water samples of different depths in the same water area. Water body sample, although the water sample collection device in the notification number CN206710137U can collect water body samples of different depths in the same water area, it can only collect one-time samples of the same water area, and it is difficult to carry out secondary collection for different positions in the same water area
