[0002] River water sampling refers to the process of collecting water samples from rivers, lakes or other water bodies for analysis and inspection. This process usually includes measuring parameters such as water temperature, pH value, dissolved oxygen content, etc. to understand the water quality and possible pollutants. River water sampling is an important step in environmental monitoring and water quality assessment, which can help us better protect and manage water resources and ensure the health of humans and ecosystems.

[0003] In the prior art, water sampling is usually done manually by using a water sampling cup to sample river water in the river. However, the water sampling cup can only sample the water on the surface of the river, which is not convenient for sampling water at different depths in the river. This limitation makes it difficult to conduct a comprehensive analysis of the river water. To solve this problem, we propose a river water sampling device. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] The utility model provides a technical solution: Figure 1-Figure 6 As shown, in this embodiment, a river water sampling device includes a submersible track 1 and a fixed pile 3, one side of the submersible track 1 is fixedly connected to a fixed plate 2, a positioning notch 16 is provided inside the fixed plate 2, the inner wall of the positioning notch 16 is slidably connected to the fixed pile 3, one side of the submersible track 1 is provided with a water sampling structure, the inside of the submersible track 1 is provided with a lifting assembly, the lifting assembly is used to drive the water sampling structure to move, the bottom of the submersible track 1 is fixedly connected to a conical head 20, the water sampling structure includes an auxiliary plate 19, the auxiliary plate 19 is slidably connected between the inner walls of the submersible track 1, one side of the auxiliary plate 19 is fixedly connected to a sampling barrel 7 and a mounting plate 8, the sampling barrel 7 and the mounting plate 8 are fixedly connected A sealing tube 9 is connected, and a pneumatic piston pump 10 is fixedly installed on the top of the mounting plate 8. The movable end of the pneumatic piston pump 10 passes through the sealing tube 9 and extends to the inside of the sampling tube 7 and is fixedly connected to a connecting rod 14. The end of the connecting rod 14 away from the sealing tube 9 is fixedly connected to a piston plate 13. The outer side of the piston plate 13 contacts the inner wall of the sampling tube 7. One side of the sampling tube 7 is fixedly connected to a water sample inlet and outlet 12. A key groove 17 is provided on the inner side of the positioning notch 16.

A water-proof cover 11 is provided on the outer side of the pneumatic piston pump 10 and located on the top of the mounting plate 8, and a sealing sleeve 15 is sleeved on the outer side of the piston plate 13.

[0024] When sampling water in a river, first select a submersible track 1 of a specific specification according to the depth of the river, then install and fix the fixed pile 3 above the sampling point of the river, and if it is in the center of the river, install and fix it on the hull. When connecting, use the cooperation of the flat key 18 and the key slot 17 to sleeve the fixing plate 2 on the outside of the fixing pile 3, so that the submersible track 1 is submerged in the water, and at the same time, the conical head 20 at the bottom of the submersible track 1 contacts the mud and sand at the bottom of the river. After completing the erection of the river water sampling device, the water sampling structure is driven into the water by the lifting assembly, and at the same time, the water sampling structure is submerged in the water. The sampling tube 7 is moved to the sampling depth, and then the pneumatic piston pump 10 is used to drive the piston plate 13 to move between the inner walls of the sampling tube 7, so that the water outside the sampling tube 7 enters the sampling tube 7 through the water sample inlet and outlet 12 under the action of pressure.

[0026] The servo motor 6 drives the lifting screw 4 to rotate between the inner walls of the submersible track 1, so that the lifting block 5 drives the water sampling structure to move up and down on one side of the submersible track 1 under the action of the lifting screw 4, thereby facilitating the water sampling structure to be moved to the corresponding height, making it convenient for the staff to sample the water at a specified depth.

[0027] The utility model provides a river water sampling device, and the specific working principle is as follows: when sampling the river water, firstly, a submersible track 1 of a specific specification is selected according to the depth of the river, and then the fixed pile 3 is installed and fixed above the sampling point of the river. If it is in the center of the river, it is installed and fixed on the hull. When connecting, the flat key 18 and the key slot 17 are used to fit the fixing plate 2 on the outside of the fixing pile 3, so that the submersible track 1 is submerged in the water, and at the same time, the conical head 20 at the bottom of the submersible track 1 contacts the mud and sand at the bottom of the river. After the installation of the river water sampling device is completed, the servo The motor 6 drives the lifting screw 4 to rotate between the inner walls of the diving track 1, so that the lifting block 5 drives the water sampling structure to be submerged in the water under the action of the lifting screw 4, and at the same time, the sampling tube 7 is moved to the sampling depth, and then the pneumatic piston pump 10 is used to drive the piston plate 13 to move between the inner walls of the sampling tube 7, so that the water outside the sampling tube 7 enters the sampling tube 7 through the water sample inlet and outlet 12 under the action of pressure. After the sampling is completed, the servo motor 6 drives the lifting screw 4 to rotate again, so that the lifting block 5 drives the sampling tube 7 and the sample water to separate from the water surface, which is convenient for the staff to collect the sample water.
