Description

Technical Field

[0001] The invention belongs to the technical field of environmental monitoring, and in particular relates to an intelligent water sampling device. Background Art

[0002] As an essential substance for the survival of humans, animals and plants, water plays a vital role in social development, ecological balance and human survival. Therefore, in the process of environmental quality monitoring, it is often necessary to sample water and then test the sampled water to determine the quality of the water.

[0003] The current conventional groundwater sampling operation process: 1) First, use a water level meter to measure the water level depth, and then place the sampler (water pump) into the groundwater sampling well through a water pipe; 2) The groundwater is lifted by a water pump, and then the flow rate is adjusted by a flow meter, and sampling is performed according to the specified flow rate. When sampling, some monitoring indicators need to be filtered before sampling; and before sampling, the water quality needs to be tested for certain indicators, such as pH, dissolved oxygen, and turbidity. Sampling can only be performed if it meets the requirements; 3) Finally, the water sample is transported to a sampling bottle for collection. Conventional surface water sampling is to place the sampler into the water on a boat, bridge or shore, collect the water sample with the sampler, and then transfer it to the sampling bottle for collection.

[0004] In the process of water sampling, it is often necessary to collect water samples at different depths or locations, so it is necessary to accurately measure the sampling depth, water level and water sample location, etc. However, conventional sampling requires the cooperation of multiple instruments to meet the sampling requirements. And when sampling, filtering sampling is required for certain detection indicators. The existing negative pressure filtration sampling method first requires a water pump to collect water samples, and then manually inject the water samples into the filtration device in batches for filtration and then transfer them to the final sample sampling bottle. This sampling method has the problems of slow sampling speed, poor sampling operation continuity, cumbersome operation process and labor consumption.

[0005] Therefore, in view of the problems existing in the above-mentioned sampling process, relevant technological innovations are urgently needed to solve the problems. Summary of the invention

The side wall of the shaft sleeve 45 is provided with a plurality of drainage holes 51 located inside the rotating sleeve 49. The side wall of the rotating sleeve 49 is connected with a water pump 19, which is fixed in the outer box 1. The drainage end of the water pump 19 is connected to the fine filter assembly, and the fine filter assembly is detachably connected with the sampling bottle 13. The sliding sleeve 31 is slidingly sleeved on the conduit 30, and a rebound mechanism is connected between the sliding sleeve 31 and the conduit 30.
