[0026] like Figures 1 - 6 As shown, the sampling device for sewage treatment provided in this embodiment includes a sampling barrel 1, and a piston ball 2 located on the inner side of the sampling barrel 1, a connecting plate 3 is fixedly connected to the inner wall of the sampling barrel 1, a through hole 4 cooperating with the piston ball 2 is opened in the middle of the connecting plate 3, a mounting plate 5 fixedly connected to the inner wall of the sampling barrel 1 is provided below the connecting plate 3, a spring 6 located on the inner side of the through hole 4 is fixedly connected between the piston ball 2 and the mounting plate 5, a first pull rope 7 is fixedly connected to the top of the piston ball 2, and a push-pull plate 8 located at the bottom of the connecting plate 3 is slidably installed on the front side of the sampling barrel 1.

[0027] By setting the piston ball 2, the through hole 4 and the spring 6, the diameter of the piston ball 2 is larger than the inner diameter of the through hole 4. Therefore, under the pulling force of the spring 6, the piston ball 2 will block the through hole 4, and the sampling tube 1 is placed in the sewage. The sampling tube 1 will sink under the action of gravity. When it is lowered to the required depth, the first pull rope 7 is pulled and the sampling tube 1 is released. At this time, the piston ball 2 is separated from the through hole 4, and the sewage can enter the sampling tube 1. The first pull rope 7 is released, and the piston ball 2 closes the through hole 4 again under the action of the spring 6. The operation is simple and convenient, and sewage sampling at different depths can be performed, which is highly practical. By setting the push-pull plate 8 and the mounting plate 5, the sliding push-pull plate 8 can adjust the size of the offset between the first filter hole 501 and the second filter hole 801, thereby adjusting the filter aperture, which is convenient for sampling in sewage with more impurities.

[0028] In this embodiment, if Figure 1 , Figure 2 and Figure 3 The outer wall of the sampling tube 1 is movably provided with a counterweight 9, which is provided with a water-permeable hole 10. The outer wall of the sampling tube 1 is fixedly connected with a plurality of bearing plates 11 located below the counterweight 9. The counterweight 9 is provided to increase the deadweight.

Through the setting of the slide groove 15, the slide groove 15 and the push-pull plate 8 have an interference fit, which is convenient for adjustment. Through the setting of the first filter hole 501 and the second filter hole 801, the sliding push-pull plate 8 can adjust the size of the offset between the first filter hole 501 and the second filter hole 801, thereby adjusting the size of the filter aperture.

[0032] Step 1: Slide the push-pull plate 8 to adjust the offset between the first filter hole 501 and the second filter hole 801, and pull the second pull rope 14 to vertically place the sampling tube 1 in the sewage;

[0033] Step 2: The sampling tube 1 sinks under the action of gravity. When it reaches the required height, the first pull rope 7 is pulled and the second pull rope 14 is loosened. At this time, the piston ball 2 is separated from the through hole 4, and the sewage enters the sampling tube 1;

[0034] Step 3: After the sampling is completed, the first pull rope 7 is released, the piston ball 2 closes the through hole 4 under the action of the spring 6, and the second pull rope 14 is pulled to retract the sampling tube 1.

[0035] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto.
