Description

Technical Field

[0001] The utility model relates to the technical field of storage tubes, in particular to a storage tube for sampling contaminated water. Background Art

[0002] When staff members take samples of contaminated water sources outdoors, they need to use storage tubes to store the sampled water sources for easy carrying. However, the water samples collected in the wild are complicated. There may be floating impurities, mud and sand in the contaminated water sources. Although some impurities can be removed by filtering, a large number of fine impurities still enter the storage tube with the water sample. When the water sample in the storage tube needs to be tested in the detection room later, during the process of pouring out the water sample in the storage tube, some of the impurities in the water sample will be discharged with the contaminated water, and some impurities will adhere to the inner wall of the storage tube. If these impurities are not completely discharged from the storage tube, it will have a certain impact on the data of the contaminated water sample detection, resulting in a decrease in the accuracy of the data. Therefore, the staff members are required to use tools to inhale a part of the discharged water sample, and then rinse the impurities on the inner wall of the storage tube. After repeating this several times, the impurities attached to the inner wall of the storage tube can be cleaned out of the storage tube. The operation process is cumbersome and reduces the efficiency of the detection of contaminated water samples. Utility Model Content

[0003] The utility model discloses a storage tube for polluted water sampling, which solves the problem that it is difficult to clean out the impurities remaining in the storage tube after the water sample in the storage tube is poured out.

[0004] In order to solve the above technical problems, the present invention specifically adopts the following technical solutions:

[0005] A storage tube for sampling contaminated water includes a tube body, a rubber tube is provided in the tube body, a pull rod is provided at the bottom of the rubber tube, the top of the rubber tube extends to the outside of the rubber tube, an upper sealing cover is threadedly connected to the top of the tube body, the part of the rubber tube close to the upper sealing cover is fixed to the inner wall of the tube body; the top of the upper sealing cover is connected to a fixing cylinder for the top of the pull rod to enter.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] After the upper sealing cover is opened and the collected contaminated water sample is injected into the rubber tube, the upper sealing cover is then threadedly connected to the top of the tube body to seal the rubber tube and complete the storage of the contaminated water sample, while the tube body can protect the rubber tube. When the contaminated water sample in the rubber tube needs to be poured out for testing, the upper sealing cover can be separated from the tube body first, the top end of the pull rod is located above the tube body, and the contaminated water sample in the rubber tube is poured out. Then, the staff pulls the rubber tube toward the outside of the tube body through the pull rod, so that after the rubber tube is pulled to the outside of the tube body, the inner wall of the rubber tube is completely exposed to the outside, completing the replacement of the inner and outer walls of the rubber tube. Then, the staff can control the part of the rubber tube with impurities attached to enter the contaminated water sample through the pull rod, so that the impurities fall off the rubber tube, completing the cleaning of the impurities, and then restore the rubber tube through the pull rod. The utility model can quickly clean the impurities attached to the inner wall of the rubber tube, is easy to operate, improves the detection efficiency of the contaminated water sample, and ensures the accuracy of the subsequent contaminated water sample detection data.

[0011] The specific contents of the present utility model are described in detail below with reference to the accompanying drawings and embodiments.

[0012] like Figure 1 and Figure 2 As shown, the utility model provides a storage tube for contaminated water sampling, including a tube body 1, a rubber tube 2 is provided in the tube body 1, a pull rod 3 is provided at the bottom of the rubber tube 2, the top of the rubber tube 2 extends to the outside of the rubber tube 2, an upper sealing cover 4 is threadedly connected to the top of the tube body 1, and the part of the rubber tube 2 close to the upper sealing cover 4 is fixed to the inner wall of the tube body 1; the top of the upper sealing cover 4 is connected to a fixing cylinder 41 for the top of the pull rod 3 to enter.

[0013] like Figure 1 and Figure 2As shown, the bottom of the tube body 1 is threadedly connected to a lower sealing cap 5, a rubber ring 51 is fixed to the bottom of the inner side of the lower sealing cap 5, and a rubber column 22 is fixed to the bottom of the rubber tube 2 and inserted into the inner side of the rubber ring 51. The rubber column 22 can be inserted into the inner side of the rubber ring 51 (the inner diameter of the rubber ring 51 decreases from top to bottom) via a pull rod 3, thereby limiting the position of the rubber tube 2 and preventing it from shaking freely within the tube body 1.

[0014] like Figure 1 As shown, the tube body 1 includes a long tube 11 and a short tube 12. The short tube 12 is threadedly connected to the top of the long tube 11, and the rubber tube 2 is fixed to the inner wall of the short tube 12; the upper sealing cover 4 and the lower sealing cover 5 are threadedly connected to the top of the short tube 12 and the bottom of the long tube 11 respectively, and the bottom of the lower sealing cover 5 is threadedly connected to a sealing cap 8 that can be threadedly connected to the top of the long tube 11. When it is necessary to load more contaminated water samples, the upper sealing cover 4 can be separated from the tube body 1, and the rubber tube 2 can be pulled from the top of the tube body 1 to the outside of the tube body 1 through the pull rod 3 to exchange the inner and outer walls of the rubber tube 2. Then, after the top and bottom of the tube body 1 are exchanged, the lower sealing cover 5 can be separated from the tube body 1, and the contaminated water sample can be injected into the tube body 1 through the end of the tube body 1 that is now at the top. The tube body 1 can be combined with the rubber tube 2 to load more contaminated water samples. When it is necessary to discharge the contaminated water sample later, the lower sealing cover 5 can be separated from the tube body 1 first. Due to the precipitation of impurities in the contaminated water sample, the impurities They are all located in the rubber tube 2, so the staff can first pinch the part of the rubber tube 2 close to the short tube 12, and due to the bendability of the rubber tube 2, tilt the end of the tube body 1 connected to the lower sealing cover 5 downward (the rubber tube 2 is still in an upright state) to pour out the contaminated water sample in the tube body 1, and the contaminated water sample in the rubber tube 2 will not be discharged; when the contaminated water sample in the tube body 1 is discharged, the short tube 12 and the long tube 11 can be separated, and then the contaminated water sample in the rubber tube 2 can be poured out (the contaminated water sample does not need to pass through the long tube 11 at this time), and the bottom of the rubber tube 2 (such as Figure 1 When the inner wall and outer wall of the rubber tube 2 shown in the figure are not replaced, the bottom of the inner side of the rubber tube 2 is pushed upward to restore the rubber tube 2 ( Figure 1 As shown in the figure, but the rubber tube 2 is not located in the long tube 11 at this time), the staff can put the part of the rubber tube 2 with impurities adhered to it into the discharged contaminated water sample to make the impurities fall off from the rubber tube 2;

[0015] At the same time, when the storage tubes are not enough, the short tube 12 and the long tube 11 can also be disassembled for emergency use; first inject the contaminated water sample into the long tube 11, separate the sealing cap 8 from the lower sealing cover 5, and then thread the sealing cap 8 with the top of the long tube 11 to seal the top of the long tube 11; the staff can also open the upper sealing cover 4, inject another contaminated water sample into the rubber tube 2, and then thread the upper sealing cover 4 with the short tube 12 together; the rubber tube 2 and the long tube 11 can be disassembled and used to store two different contaminated water samples.

[0016] like Figure 1 As shown, the long tube 11 is provided with a threaded connection tube 6, the top of which is provided with an annular thread groove, into which a protective tube 61 is threadedly connected, and a connection ring 62 is fixed to the top of the protective tube 61, which contacts the top of the connection tube 6. When a large amount of contaminated water samples needs to be stored, the upper sealing cover 4 is separated from the short tube 12, and the bottom of the rubber tube 2 is moved from the top of the tube body 1 to the outside of the tube body 1. The rubber tube 2 and the tube body 1 now form a larger storage container; the staff can then rotate the connection tube 6 to move the connection tube 6 toward the rubber tube 2, cover a portion of the rubber tube 2, and then rotate the connection ring 62 to move the protective tube 61 toward the outside of the connection tube 6, so that the protective tube 61 cooperates with the connection tube 6 to completely cover the rubber tube 2, effectively protecting the rubber tube 2.

[0017] like Figure 1 As shown, a connecting post 21 is fixed to the bottom of the rubber tube 2, and the top of the connecting post 21 is threadedly connected to the bottom of the pull rod 3. When a large amount of contaminated water samples needs to be loaded, the rubber tube 2 is pulled from the top of the tube body 1 to the outside of the tube body 1, and the pull rod 3 can be separated from the connecting post 21 to prevent the pull rod 3 from affecting the subsequent storage of the tube body 1.

[0018] like Figure 1 As shown, a rubber block 7 is fixed to the connecting tube 6, and a hole is formed at the top of the rubber block 7 for the end of the pull rod 3 to pass through. When the pull rod 3 is separated from the connecting column 21, the top end of the pull rod 3 can be passed through the hole in the rubber block 7 (the inner diameter of the hole decreases from top to bottom), which serves as a storage for the pull rod 3.

[0019] When in use, open the upper sealing cover 4 and inject the collected contaminated water sample into the rubber tube 2, then screw the upper sealing cover 4 and the top of the tube body 1 together to seal the rubber tube 2 and complete the storage of the contaminated water sample, and the tube body 1 can protect the rubber tube 2; when the contaminated water sample in the rubber tube 2 needs to be poured out for testing, the upper sealing cover 4 and the tube body 1 can be separated first, and then the contaminated water sample in the rubber tube 2 is poured out, and then the staff pulls the pull rod 3 located above the tube body 1 to move the rubber tube 2 toward the outside of the tube body 1. After the rubber tube 2 is pulled to the outside of the tube body 1, the inner wall of the rubber tube 2 is completely exposed to the outside, completing the replacement of the inner and outer walls of the rubber tube 2; then the staff can control the part of the rubber tube 2 with impurities attached to it through the pull rod 3 to enter the contaminated water sample, so that the impurities fall off the rubber tube 2, completing the cleaning of the impurities, and then restore the rubber tube 2 through the pull rod 3.

[0020] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
