Embodiment Construction
[0022] refer to Figure 1-2 , a layered sampling device for water quality monitoring, comprising a guide rod 1 and a detection tube 8, the lower end of the guide rod 1 is fixed with a limiter 4 and pins 5, the limiter 4 is used to limit the maximum depth of the detection tube 8 descent, The pin 5 is pointed and conical, which can assist the bottom of the guide rod 1 to be inserted into the river bed or the bottom of the lake. The outer side of the detection tube 8 is provided with a guide sleeve 2, which is slidably sleeved on the guide rod 1, and the guide sleeve 2 is connected to the guide rod 1. The cooperation can ensure that the detection tube 8 moves in the vertical direction all the time. Two elastic bags 3 are arranged in parallel on the outer wall of the detection tube 8. A first buffer mechanism and a second buffer mechanism are arranged outside the detection tube 8. The first buffer mechanism Including the first buffer box 6, the first buffer box 6 communicates with...

The invention discloses a water quality monitoring stratified sampling device, which comprises a guide rod and a detection tube, the lower end of the guide rod is fixedly provided with a stopper and a pin, the outer side of the detection tube is provided with a guide sleeve, the guide sleeve slidably sleeves the guide rod, the outer side wall of the detection tube is provided with two elastic bags in parallel, and the elastic bags are arranged in the guide sleeve. A first buffer mechanism and a second buffer mechanism are arranged outside the detection tube, and the first buffer mechanism comprises a first buffer box. The equipment is small in size, water bodies with different depths can be automatically sampled in batches from bottom to top in the one-time putting process, the obtained water samples cannot be mutually polluted, and the correctness of the sampling result can be ensured; when the depth of the water body is small, a worker can directly see floating of the detection pipe through naked eyes, the worker can conveniently take back the detection pipe in time, when the depth of the water body is large, the detection pipe actively floats, the worker can conveniently recycle the detection pipe, and the recovery difficulty of the detection pipe is reduced.
Description
technical field [0001] The invention relates to the technical field of water quality monitoring, in particular to a layered sampling device for water quality monitoring. Background technique [0002] When measuring water quality pollutants, it is necessary to sample water bodies at different depths to obtain complete monitoring data. Most of the existing sampling equipment is snorkeling devices, which disturb the water body significantly, and only It can take a single sample at a certain depth. If multiple sets of water samples need to be obtained, the snorkeling device needs to be put in multiple times. In addition, the snorkeling device needs to be thoroughly cleaned after one sampling to avoid contamination of subsequent samples. The workload of sampling personnel is greatly increased. Therefore, we propose a layered sampling device for water quality monitoring. Contents of the invention [0003] The purpose of the present invention is to solve the problem that in the ...
