[0022] The technical solution in the embodiment of the present application is to solve the problems in the above-mentioned background technology, and the general idea is as follows: An inner cylinder 2 is movably installed in an outer cylinder 1. During the sampling process, first, by rotating the inner cylinder 2, the second through port 23 coincides with the first through port 11. At this time, the sewage flowing in the pipeline will enter the inner cylinder 2 and flow into the sampling tube 6 for sampling. After the sampling work is completed, only by rotating the inner cylinder 2, the first through port 11 and the second through port 23 are staggered. At this time, the cylinder wall of the inner cylinder 2 will cover and seal the first through port 11, so as to isolate the sewage. At this time, the staff can open the sealing cover 3 and take out the sampling tray 5 and the sampling tube 6 for use, thus completing the collection and sampling work. The utility model is convenient for the staff to collect and sample the sewage flowing in the pipeline. Moreover, the setting of multiple groups of sampling tubes 6 can collect multiple samples at one time, thus providing convenience and accuracy for the detection work.

[0023] Example: Refer to Figure 1 - Figure 4 As shown in the figure, a sampling device for industrial sewage detection in this embodiment includes an outer cylinder 1. An inner cylinder 2 is movably installed in the middle of the inner side of the outer cylinder 1. First through ports 11 are provided in the middle of both ends of the outer cylinder 1, and second through ports 23 are provided in the middle of both ends of the inner cylinder 2.

[0024] Among them, when the first through port 11 and the second through port 23 are in a coincident state, the sewage in the pipeline will flow into the inner cylinder 2. When the inner cylinder 2 rotates so that the first through port 11 and the second through port 23 are in a staggered state, the cylinder wall of the inner cylinder 2 will cover and seal the first through port 11. At this time, the sewage in the pipeline will be isolated to prevent the sewage from flowing into the inner cylinder 2.

[0025] A sampling assembly is arranged in the middle of the inner side of the inner cylinder 2. The sampling assembly includes a sampling tray 5. The sampling tray 5 is located at the bottom of the inner side of the inner cylinder 2. Multiple groups of sampling tubes 6 are arranged in the middle of the upper end of the sampling tray 5. Among them, when the sewage flows into the inner cylinder 2, it will flow into the sampling tubes 6, so that the sampling tubes 6 collect and sample the sewage.

[0026] A support column 4 is fixedly installed in the middle of the upper end of the sampling tray 5. A sealing cover 3 is arranged at the top of the support column 4. The sealing cover 3 is installed on the top of the inner cylinder 2. Among them, by pulling the sealing cover 3, under the action of the support column 4, the sampling tray 5 can be taken out of the inner cylinder 2, thus facilitating the staff to take or install multiple groups of sampling tubes 6 on the sampling tray 5.

[0027] At the upper end of the sampling tray 5, multiple groups of fixing holes 51 are provided. The multiple groups of fixing holes 51 are distributed in an annular array. The fixing holes 51 are set to have an internal thread structure. In the middle of the bottom end of the sampling tube 6, a mounting seat 61 with an external thread structure is provided. The mounting seat 61 is threadedly installed in the middle of the inner side of the fixing hole 51. Through the mounting seat 61, the sampling tube 6 is fixedly installed on the sampling tray 5, thereby improving the stability of the installation of the sampling tube 6 and avoiding the impact and tipping of the sampling tube 6 caused by the flow of sewage when collecting sewage, resulting in the sampling work of sewage.

[0028] At the upper inner side of the outer cylinder 1, an annular limiting groove 13 is provided. On the upper outer surface of the inner cylinder 2, an annular limiting ring 22 is provided. The limiting ring 22 is movably installed in the middle of the inner side of the limiting groove 13. The limiting ring 22 plays a role in limiting, avoiding the inner cylinder 2 from falling off the outer cylinder 1 and improving the stability of the inner cylinder 2 when rotating.

[0029] The sealing cover 3 is hermetically connected to the inner cylinder 2. The sealing cover 3 plays a sealing role, avoiding sewage from flowing out from the upper inlet of the inner cylinder 2.

[0030] Among them, the sealing cover 3 and the inner cylinder 2 are fixedly connected through multiple groups of locking buckles. The setting of the locking buckles provides convenience for the installation or disassembly of the sealing cover 3.

[0031] In some examples, on the upper sides of both ends of the inner cylinder 2, handle grips 21 are provided. The handle grips 21 are located on both sides of the upper end of the outer cylinder 1. When the staff holds the handle grips 21 with both hands and rotates, the inner cylinder 2 can be rotated, so that the first through port 11 and the second through port 23 are in a coincident or staggered state.

[0032] In some examples, on the upper outer surface of the outer cylinder 1, an annular mounting disc 12 is provided. The setting of the mounting disc 12 facilitates the staff to hermetically install the outer cylinder 1 on the sewage pipe for use.

[0033] In some examples, in the middle of the upper end of the sealing cover 3, an observation window 31 made of a transparent material is provided, which is convenient for the staff to observe the sampling situation of the sampling tube 6.

[0034] The working principle of the present utility model is:

[0035] First, the sampling device is installed on the sewage pipe through the mounting disc 12. When it is necessary to collect and sample sewage, first lift the sealing cover 3, install the sampling tray 5 into the inner cylinder 2, then cover the sealing cover 3 and limit and fix it through multiple groups of locking buckles;

[0036] At this time, the staff only needs to rotate the inner cylinder 2 by holding the handles 21 on both sides of the upper end of the holding cylinder 2 until the second through port 23 coincides with the first through port 11. At this time, the sewage in the pipeline will flow into the inner cylinder 2 from the first through port 11. When the sewage enters the inner cylinder 2, it will flow into the sampling tube 6. After the staff sees through the observation window 31 that the sampling tube 6 has completed the sampling work, rotate the inner cylinder 2 again to make the second through port 23 stagger with the first through port 11. At this time, the barrel wall of the inner cylinder 2 will cover and seal the first through port 11 to prevent external sewage from continuing to flow into the inner cylinder 2, thus facilitating the staff to open the sealing cover 3 to take out the sampling tube 6 for disassembly and removal.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the description in the specification only illustrate the principles of the present invention.
