Description

Technical Field

[0001] The utility model relates to a sampler, in particular to an ecological water quality sampler, belonging to the technical field of water quality collection. Background Art

[0002] With the development of society, the water quality in the environment has been more or less affected. In order to better understand the concentration and distribution of various pollutants in the water and to evaluate the quality of the water, sample water is usually collected from the waters that need to be tested, and then brought back to the laboratory for water quality data testing.

[0003] According to a Chinese patent document with the announcement number CN 211627079U, a water quality sampler for ecological environment monitoring is disclosed, which includes a tube body, a connecting pipe, a sealing pad, a first piston, a first round rod, a first guide ring, a silicone grip sleeve, a finger grip groove, a fixing ring, a connecting strip, an arc-shaped connecting piece, a water sample storage cylinder, a first valve, a curved pipe, a second valve, a short pipe, a second guide ring, a second round rod and a second piston. The utility model has a reasonable structure. Through the cooperation of the tube body, the connecting pipe, the first piston and the first round rod, the water sample can be lifted to the inside. Further, through the cooperation of the water sample storage cylinder, the first valve, the curved pipe, the second valve, the short pipe, the second round rod and the second piston, the water sample can be sucked into the water sample storage cylinder for storage. Through multiple water sample storage cylinders, water samples of different monitoring areas can be stored separately.

[0004] Based on the search of the above patents and in combination with the equipment in the prior art, it is found that when the above equipment is used, the water sample can be lifted to the inside through the cooperation of the tube body, the connecting tube, the first piston and the first round rod, and then stored in the storage cylinder. However, depending on the different water quality of the sampled water area, there are generally impurities in the water, and they are not the same. When sampling the water area, if there is no need to detect the impurities in the water quality, the impurities in the water will be attached to the inner wall of the tube body while being drawn into the bottle body. Because the device can collect and store different water areas in a single use, over time, the impurities attached to the tube body will affect the data information of the sampled water, and then cause the experimental data of the sampled water to be inaccurate.

Then, when passing through the fan-shaped filter screen 8, the impurities in the water will be further filtered. Finally, the filtered water flows into the long tube body 1 and is then pumped into the bottle body 19, reducing the accumulation of impurities in the long tube, thereby increasing the service life of the long tube body 1.
