Description

Technical Field

[0001] This utility model relates to the field of water environment engineering sampling technology, specifically a sampling device for water environment engineering testing. Background Technology

[0002] In the field of water environment monitoring (such as water quality testing of rivers, lakes, and reservoirs), accurately obtaining undisturbed water samples at a specified depth is the core prerequisite for ensuring data reliability. During water environment engineering sampling operations, multiple sampling points are sometimes required, which necessitates the separate storage of numerous sample bottles. However, a large number of sample bottles is not conducive to outdoor use, and each sampling requires pouring the water sample into the storage bottle, making it cumbersome to use. Therefore, this application proposes a sampling device for water environment engineering testing to solve the above problems. Utility Model Content

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] like Figure 1-3 As shown, this utility model provides a technical solution: a sampling device for water environment engineering testing, comprising a storage box 1, multiple sampling bottles 4 and a sampler. The storage box 1 is provided with multiple sampling bottle slots 2 and a sampler slot 3. The sampling bottles 4 are placed in the sampling bottle slots 2 and the sampler is placed in the sampler slot 3. By placing the sampling bottles 4 and the sampler in the slots respectively, the overall structure of the device is compact and convenient for outdoor use.

[0022] The sampler includes a suction tube 5, which is a piston-push rod type suction tube. The suction end of the suction tube 5 is equipped with a suction tube 7 and a suction tube 8. The suction tube 7 is connected to the suction tube 5. The suction end of the suction tube 5 is connected to one end of the mounting shell 6, and the other end of the mounting shell 6 is connected to the receiving tube 10. The suction tube 8 passes through the mounting shell 6 and the receiving tube 10 and is connected to a flexible tube 9. The sampling bottle 4 is assembled inside the mounting shell 6. A compression pad, made of rubber, is provided inside the mounting shell 6 facing the receiving tube 10. The compression pad ensures a tighter contact between the bottle mouth of the sampling bottle 4 and the rubber ring 12 after the sampling bottle 4 is placed inside the mounting shell 6, preventing air leakage and facilitating the placement and removal of the sampling bottle 4 within the mounting shell 6. The suction end of the suction tube 5 is equipped with a rubber ring 12, and the suction tube 7 and suction tube 8 are... Place the sample bottle 4 inside the rubber ring 12, with the bottle mouth corresponding to the rubber ring 12. Insert the sample bottle 4 into the mounting shell 6, and lock the bottle mouth of the sample bottle 4 into the rubber ring 12. At this time, the extraction tube 7 and the suction tube 8 will both correspond to the bottle mouth of the sample bottle 4. Place the hose 9 in the water source. By pulling the push rod of the extraction tube 5, the piston moves, creating a negative pressure in the extraction tube 5. Simultaneously, a negative pressure is created in the sample bottle 4 through the extraction tube 7. Water is drawn into the sample bottle 4 using the suction tube 8 and the hose 9. After extraction, the sample bottle 4 is taken out, the bottle mouth is sealed, and it is placed in the sample bottle slot 2 of the storage box 1 to complete the sampling. This design allows water samples to be directly extracted into the sample bottle 4, avoiding the cumbersome steps of pouring water samples into the storage bottle 4 during traditional sampling, thus improving sampling efficiency.

[0023] The hose 9 is wound around the storage tube 10, and the storage tube 10 is provided with a slot 11 for locking and fixing the end of the hose 9. When not in use, the hose 9 can be stored by winding it around the storage tube 10 and inserting the end of the hose 9 into the slot 11.

[0024] The operational steps for this application are as follows:

[0025] Insert the sampling bottle 4 into the mounting housing 6, and tighten the bottle opening of the sampling bottle 4 into the rubber ring 12. At this time, the extraction tube 7 and the suction tube 8 will be aligned with the bottle opening of the sampling bottle 4. Place the flexible tube 9 into the water source. Pull the push rod of the extraction tube 5 to move the piston, creating a negative pressure in the extraction tube 5. Simultaneously, a negative pressure is created in the sampling bottle 4 through the extraction tube 7. Use the suction tube 8 and the flexible tube 9 to draw water into the sampling bottle 4. After the extraction is completed, take out the sampling bottle 4, seal the bottle opening, and place it in the sampling bottle slot 2 of the storage box 1 to complete the sampling.
