[0002] With the acceleration of industrialization and the improvement of urbanization, river water pollution is becoming increasingly serious, posing a serious threat to aquatic ecosystems and human health. In order to effectively monitor and evaluate river water quality, scientifically and accurately collecting silt samples in rivers and conducting subsequent analysis has become an important task.

[0003] However, the existing river water pollution sampling devices can only sample river water, but cannot directly sample the silt in the river. Even if some devices can collect silt samples, there are often problems such as poor separation effect and slow separation speed in the process of separating silt and water, which affects the accuracy of the analysis results. For this reason, we propose a sampling device for river water pollution control. Utility Model Content

[0026] The extraction device 6 is arranged in the inner cavity of the waterproof housing 1 and is used to extract the sludge sample extracted from the dredging funnel 2 .

[0027] Furthermore, the outer shell of the waterproof housing 1 is made of waterproof and anti-corrosion material and is tightly connected to the upper side of the dredging funnel 2.

[0028] Furthermore, a sampling pipe 9 is fixedly connected to the lower end of the sampling dish 8 away from the waterproof shell 1, and a switch valve is provided on the sampling pipe 9. One end of the sampling pipe 9 is connected to the inner cavity of the sampling dish 8, and a screen 10 is fixedly connected to the inner wall of the sampling dish 8 corresponding to the top of the sampling pipe 9.

[0029] Furthermore, the extraction device 6 includes a sampling pipe 11, a sampling outlet pipe 12, a sampling inlet through hole 13 and a sampling auger 14. The sampling pipe 11 is fixedly connected to the top of the inner wall of the waterproof shell 1, and the lower end of the sampling pipe 11 is fixedly inserted on the upper side of the dredging funnel 2 and extends into the inner cavity of the dredging funnel 2. A sampling inlet through hole 13 is opened at the lower end of the side of the sampling pipe 11, and the top inner wall of the sampling pipe 11 is rotatably connected to the sampling auger 14. The sampling outlet pipe 12 is fixedly connected to the inner cavity of the waterproof shell 1 on the side of the sampling pipe 11, and the other end of the sampling outlet pipe 12 is connected to the mud outlet 7.

[0030] Furthermore, the top of the sample lifting auger 14 is fixedly connected to the rotating shaft of the driving motor 4, and the bottom of the sampling pipe 11 is an open structure.

[0031] Furthermore, one side and the bottom of the dredging funnel 2 are both open structures, and a mud shoveling net 15 is fixedly connected to the bottom of the dredging funnel 2, and a clamping block 16 is fixedly connected to the end of the mud shoveling net 15 away from the opening side of the dredging funnel 2, and a buckle 17 is hinged on the side of the dredging funnel 2 away from the sampling dish placement seat 3.

[0032] Furthermore, the mud shoveling net 15 is a hollow iron net, and the lower end of the buckle 17 is movably connected to the clamping block 16.

[0033] Working principle: When the device is needed to sample river water pollution, first, the operator stably places the device at the location where sampling is required in the river by holding the handle 5, aligns the opening of the dredging funnel 2 with the silt layer at the bottom of the river, and manually samples into the inner cavity of the dredging funnel 2. The dredging funnel 2 has a large opening area, which can ensure that a representative silt sample is collected. At the same time, since the silt is initially concentrated and precipitated in the funnel, it helps to initially remove excess water and impurities therein, thereby improving the quality of the sample. After the initial sampling is completed, the device is extracted to a convenient place for operation by holding the handle 5. Then, by starting the driving motor 4, the driving motor 4 drives the sample auger 14 to rotate in the sampling pipe 11. The rotation of the sample auger 14 extracts the sludge in the dredging funnel 2 and lifts it upward through the sampling pipe 11. When it is lifted to the sampling pipe 12, the sludge flows into the sampling dish 8 through the mud outlet 7. After the sample enters the sampling dish 8, it passes through the screen 10 to ensure that the sludge sample entering the sampling dish 8 is pure and dry, and the river water sample at the bottom can be taken out through the sampling pipe 9. When the sludge sample is collected, the operator can remove the dredging funnel 2 from the device by opening the buckle 17. At this time, the clamping block 16 is disconnected from the dredging funnel 2, which is convenient for the operator to clean and maintain the dredging funnel 2. At the same time, the sampling dish 8 can be easily taken out from the sampling dish placement seat 3 for subsequent experiments and analysis.
