Description

Technical Field

[0001] The utility model relates to the technical field of water source sampling, in particular to a sampling device for reservoir ecological environment monitoring. Background Art

[0002] Water quality testing is to collect water samples from polluted water bodies and obtain basic data on water pollution through analysis and measurement. In order to understand the ecological environment near the reservoir, staff can quickly understand it through water quality testing.

[0003] When sampling water source monitoring, most samples are taken directly with the help of simple containers. Although it is convenient and fast, it can only be applied to shallow water surface sampling. When sampling deep water sources, more professional sampling devices are needed, such as the utility model with publication number CN217878468U. This patent discloses a sampling device for reservoir water quality detection. The sampling device for reservoir water quality detection places a sampling cup in a placement slot, pulls the handle to drive the splint to separate from the water pump, and then slides the connecting frame according to the scale mark on the surface of the water pump, so that the connecting frame can be moved to the required scale. After the water pump is placed in the water, the buoyancy of the float plate and the gravity of the filter can be used to sink the filter to the depth required for sampling, and the water pump can be driven to pump water into the outlet pipe, so that the valve can be opened to put the sampled water stored in the outlet pipe into the sampling cup, and the water quality at different depths can be quickly sampled.

[0004] However, this sampling method has many shortcomings: since the suction pipe is a soft tube, it is difficult to control its vertical descent after entering the water. At the same time, even if it reaches the specified depth, the pipe cannot be fixed in position during pumping and will continue to change position, making it difficult for the suction pipe to accurately reach the sampling depth.

[0005] Therefore, it is necessary to provide a sampling device for reservoir ecological environment monitoring to solve the above technical problems. Utility Model Content

At the same time, the personnel close the valve to isolate the remaining sample water from the outside world to provide comparison data for subsequent re-testing. At the same time, the personnel can remove the nut, remove the original water storage barrel and replace it with a new one, thereby completely preserving the previously sampled samples without affecting the subsequent sampling work, effectively ensuring the stability of sample storage.
