Detailed Description
The utility model will be further described with reference to the following example and the accompanying figure 1.
A micro-power negative pressure underwater sampler comprises a waterproof shell 6, a sampling bottle 1, a sampling pipeline 8, a sampling valve 2, a negative pressure pipeline 9, a sampling pump 5, a water flow sensor 3 and a control unit 4. The waterproof housing 6 is used to house other components than the sample bottle 1 to isolate the external environment. The waterproof shell 6 has certain intensity, and the middle of the shell is provided with the sampling valve 2, the water flow sensor 3, the control unit 4, the sampling pump 5, the sampling pipeline and the negative pressure pipeline, so that the sampling device has certain waterproof capacity and can meet the requirement of underwater use. Sampling bottle 1 connects waterproof shell 6 outsidely, sampling bottle 1 and sampling pipeline sealing connection. In this embodiment, through set up the sealing washer between sampling bottle 1 and sampling pipeline, negative pressure pipeline to keep airtight, guarantee the sampling of system negative pressure. The bottle body of the sampling bottle 1 is an inert plastic bottle with certain strength, can bear certain negative pressure and does not react with a water sample.
Sampling pipeline 8 includes sampling pipe house steward 80 and sampling pipe branch pipe 81, sampling pipe branch pipe 81 with sampling pipe house steward 80 is linked together, sampling pipe branch pipe 81 has a plurality of, sampling pipe branch pipe 81 with the top of sampling bottle 1 is linked together, sampling pipe house steward's one end is stretched out waterproof shell 6 is outside, and sealed processing is done to the department of stretching out. The sampling pipe branch pipe 81 is provided with the sampling valve 2 for switching the on-off state of the sampling pipeline.
