One ends of the plurality of groups of connecting ropes 22 far away from the hanging rope 21 are respectively fixedly connected with the surfaces of the corresponding hanging rings 20. Through the setting of the suspension assembly, the user stands by the river or on the bridge, and holds the hanging rope 21 to lower the sampling container 1 to the river surface, and then performs the sewage sampling operation.

[0023] Preferably, a sampling hole 2 is opened at the bottom of the sampling container 1. An active plugging assembly is installed at the bottom of the inner cavity of the sampling container 1 and corresponding to the sampling hole 2. The plugging assembly includes a connecting plate 5 arranged in the inner cavity of the sampling container 1. A plug 6 adapted to the sampling hole 2 is fixedly installed at the bottom of the connecting plate 5. A connecting frame 7 is fixedly installed on one side of the connecting plate 5. An articulated assembly is arranged at one end of the connecting frame 7. One end of the connecting frame 7 is movably installed at the bottom of the inner cavity of the sampling container 1 through the articulated assembly. The articulated assembly includes two groups of brackets 8 fixedly installed at the bottom of the inner cavity of the sampling container 1. An articulated shaft 9 is fixedly connected between the two groups of brackets 8. An articulated hole 10 adapted to the articulated shaft 9 is opened at one end of the connecting frame 7. The inner wall of the articulated hole 10 is rotatably connected with the surface of the articulated shaft 9.

[0024] After the sampling container 1 is lowered to the river surface, it will slowly sink into the river water under the action of its own gravity. Under the action of the river water, the plug 6 will be pushed out of the sampling hole 2. At this time, the river water can flow into the sampling container 1 through the sampling hole 2. After the sampling is completed, the user can pull the hanging rope 21 to lift the sampling container 1 out of the river water. At this time, the plug 6 will block the sampling hole 2 under the pressure of the sewage in the sampling container 1 to prevent the sewage in the sampling container 1 from flowing out of the sampling hole 2; in addition, the fixed seat 3 mentioned below in this embodiment can play a limiting role on the connecting plate 5 to limit the angle of its flipping, so as to prevent the angle of its flipping from being too large and unable to cover it tightly at the sampling hole 2 under the pressure of the sewage in the sampling container 1.

[0025] Among them, a fixed seat 3 is threadedly connected to the top of the inner cavity of the sampling container 1. An installation groove 4 is formed on the surface of the fixed seat 3. A filtering component for filtering sundries in the sewage is fixedly installed in the inner cavity of the installation groove 4. The filtering component includes a filtering shell 11 fixedly installed in the inner cavity of the installation groove 4. A plurality of replaceable filter plates 12 are arranged in the inner cavity of the filtering shell 11. The top of the filtering shell 11 is detachably installed with an end cover 13 through a connecting component. The connecting component includes a threaded pipe 15 fixedly installed at the bottom of the end cover 13. A threaded groove 16 adapted to the threaded pipe 15 is formed at the top end of the filtering shell 11. The inner wall of the threaded pipe 15 is threadedly connected to the top of the filtering shell 11 through the threaded groove 16. Through holes 14 are formed at the top of the end cover 13 and the bottom of the filtering shell 11.

[0026] Through the setting of the filtering component, when pouring out the sewage in the sampling container 1, the sewage will first flow into the inner cavity of the filtering shell 11 through the through hole 14. The filter plate 12 can filter the sundries in the sewage. Through the setting of the end cover 13, in this embodiment, the end cover 13 is detachably installed on the top of the filtering shell 11 through the connecting component. After using for a long time, the user can detach the end cover 13 to clean or replace the filter plate 12.

[0027] It should be noted that a drainage component for pouring out the sewage in the sampling container 1 is installed at the top of the filtering component. The drainage component includes a drain pipe 17 communicated with the top of the end cover 13. A sealing plug 18 is inserted at the top end of the drain pipe 17. When the user needs to pour out the water sample in the sampling container 1, the whole sampling container 1 can be tilted and the sealing plug 18 can be taken out from the drain pipe 17. At this time, the water sample in the sampling container 1 can be discharged to the outside through the drain pipe 17.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
