Description

Water sample collector

Technical Field

The utility model belongs to the technical field of water quality monitoring equipment, especially, relate to a water sample collector.

Background

The quantity of water resources available in China is about 8000-9500 billion cubic meters, which accounts for about 1/3 of the total quantity, and Chinese water resource bulletin shows that the total water consumption in China has already reached 5548 billion cubic meters, and if 8000 billion cubic meters can be used according to the water resources, the utilization rate of the water resources has reached 70%, and the limit is approaching. More seriously, the treatment rate of the urban sewage in China is only about 45 percent at present, and because the treatment rate of the sewage and the waste water is low and the non-point source pollution is more and more serious, each large water system, a plurality of lakes and underground water in China are polluted to different degrees. Therefore, monitoring and detecting of water quality and water samples become a great deal of frequent work items.

Present water sampler adopts traditional rope formula well-bucket device more, the concrete description is for pulling a bucket by a rope, throw in and extract the water sample to the assigned position after, but it has an obvious shortcoming, only can extract single water layer water sample at every turn, can't realize the same time, extract different water layer water samples under the condition of the same factor, in vertical sampling process, if divide the different water layer water samples of many times collection still can lead to the mutual interference of quality of water between each sample, if change the position in the horizontal plane and carry out vertical sampling again can lead to water environmental change, finally lead to the sampling precision low, work efficiency is low, and the experimental result reference value is low.

In addition, the current water sampling bucket adopts a form that the top and the bottom of the bucket body are both provided with hinged cover bodies for conveniently and quickly sampling water, but when the bucket is lifted upwards, the problem of poor sealing exists due to the structure of the hinged cover bodies at the bottom, in the process that the bucket is lifted upwards in water, the cover at the top can be closed well due to the downward thrust of water, but the cover at the bottom cannot be pushed downwards from top to bottom due to the upward thrust of water in the lifting process, on the contrary, because of the flowing characteristic of the water body, the water body can easily stir the cover at the bottom upwards in the process, if the gravity of the cover at the bottom is insufficient, the sealing property in the bucket is damaged, the sampled water body in the bucket can be polluted by the water bodies at other positions, the monitoring result is inaccurate, and if the gravity of the cover at the bottom is too heavy, the bucket body is not easy to be pushed, so that water samples are not easy to enter from the bottom of the barrel body. And after the water sampling bucket is proposed the surface of water, the leakproofness of its bottom is also not good, leads to the water sample to flow easily, leads to the waste of experimental water sample.
