Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices for monitoring reservoir water quality, and more specifically, to a sampling device for monitoring reservoir water quality. Background Art

[0002] In the existing technology, sampling devices for monitoring reservoir water quality are important tools in environmental monitoring and water resource protection. These devices are usually used to extract water samples from reservoirs for subsequent water quality analysis and testing. However, the existing sampling devices for monitoring reservoir water quality face the problem of being unable to perform one-way sealing when in use, which seriously affects the sampling effect of the sampling device and the accuracy of water quality.

[0003] Existing sampling devices for reservoir water quality monitoring cannot achieve one-way sealing during the sampling process. In order to ensure the accuracy and reliability of the sampling results, the sampling device needs to ensure the purity of the water sample during the sampling process and prevent external contaminants from entering the sampling container. However, existing equipment often cannot effectively prevent external contaminants from entering during sampling, which may be due to unreasonable design of the sealing mechanism of the sampling device, improper selection of sealing materials, or defects in the sealing structure. In this case, external contaminants may enter the sampling container during the sampling process, thereby contaminating the sampled water sample. This will not only reduce the accuracy of the sampling results, but may also lead to misjudgment of the water quality of the reservoir. Utility Model Content

A spring 14 is sleeved on the rotating shaft 10, and the two ends of the spring 14 respectively abut against the sealing ring 7 and the one-way disk 13. The one-way disk 13 is provided with a plurality of guide rods 15. A guide hole 16 is opened on the sealing disk 12. The guide rod 15 is slidably connected in the guide hole 16. The two ends of the threaded sleeve 5 are respectively provided with fillets 17.

[0030] In this embodiment, when sampling is required, the sealing tube 2 is driven to generate negative pressure under the action of the cylinder 20, and then when the pressure exceeds the elastic force of the spring 14, the seal between the one-way disk 13 and the sealing disk 12 will be released, and then the water in the reservoir will be sucked into the sealing tube 2 through the one-way tube 3, thereby completing the suction process. When the elastic force of the spring 14 needs to be adjusted, the threaded sleeve 5 can be driven to rotate by rotating the hexagonal sleeve 8. Due to the rotation of the threads of the threaded sleeve 5 and the threaded ring 6, the position of the sealing ring 7 can be changed, so the elastic force of the spring 14 can be changed, thereby changing the sealing force, and then completing the sampling process.

[0031] See also Figure 1 and Figure 2As an implementation method of the telescopic mechanism: the telescopic mechanism includes a support frame 18, a vertical frame 19 and a cylinder 20, the support frame 18 is installed between the two airbags 1, the vertical frame 19 is installed on the support frame 18, the cylinder 20 is rotatably connected to the sealing tube 2, the sealing tube 2 is installed on the vertical frame 19, a piston rod 21 is slidably provided in the sealing tube 2, and the protruding end of the cylinder 20 is connected to the piston rod 21.

Starting the cylinder 20 can drive the movement of the piston rod 21, thereby generating negative pressure in the sealing tube 2, thereby completing the water absorption sampling process.

[0033] In summary, when the overall equipment is in use or running: when sampling is required, the sealing tube 2 is driven to generate negative pressure under the action of the cylinder 20, and then when the pressure exceeds the elastic force of the spring 14, the seal between the one-way disk 13 and the sealing disk 12 will be released, and then the water in the reservoir will be sucked into the sealing tube 2 through the one-way tube 3, thereby completing the suction process. When the elastic force of the spring 14 needs to be adjusted, the threaded sleeve 5 can be driven to rotate by rotating the hexagonal sleeve 8. Due to the rotation of the threads of the threaded sleeve 5 and the threaded ring 6, the position of the sealing ring 7 can be changed, so the elastic force of the spring 14 can be changed, thereby changing the sealing force, and then completing the sampling process.

[0034] When sampling is required, the airbag 1 is placed on the water reservoir and then moved to the corresponding position. The air cylinder 20 is started to drive the piston rod 21 to move, thereby generating negative pressure in the sealing tube 2, thereby completing the water sampling process.
