[0002] Municipal sewage treatment sampling is to monitor and evaluate the performance of sewage treatment systems, ensure compliance with environmental regulations, and make appropriate treatments and adjustments. Sampling is to collect sewage samples and analyze various parameters to understand the operating status of the treatment system.

[0003] In the prior art, some samples are taken in sewage pools through sampling barrels, and some sewage pools are open-air. During the storage process, there will be impurities or floating objects in the sewage pool. When sampling, the sampling barrel is retrieved and the sampling is carried out by digging. However, in the digging process, larger impurities and floating objects are easily caused to enter the sampling barrel, which reduces the accuracy of sampling to a certain extent. Therefore, a municipal sewage treatment sampling device is proposed to solve the above problems. Utility Model Content

[0016] As a further description of the above technical solution:

[0017] The plug plate is plugged into the outer wall of the diverter ball.

[0018] As a further description of the above technical solution:

[0020] The utility model has the following beneficial effects:

[0021] 1.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1-Figure 3 The utility model provides an embodiment: a municipal sewage treatment sampling device, including a suction tube 1, a diverter ball 2 is fixedly connected to the middle part of the suction tube 1, and both sides of the diverter ball 2 are provided with the same notches as the connecting tube 8. The inner wall of the diverter ball 2 is elastically connected to the circular tube 4 through a torsion spring 3. The top and bottom ends of the diverter ball 2 are the same as the suction tube 1, so that the sewage sample can enter the upper end part of the suction tube 1. The inner wall of the right end of the circular tube 4 is elastically connected to the plug plate 6 through a reset spring 5. The outer wall of the circular tube 4 is fixedly connected to a shielding ring 7, which can be in close contact with the inner wall of the diverter ball 2 to ensure its sealing. The outer wall of the diverter ball 2 is fixedly connected to a connecting tube 8, which is connected to a sampling tube 9 through a joint and can be installed and disassembled at any time. A sampling tube 9 is provided at the end of the connecting tube 8, and a fixing mechanism is provided on the outer wall of the suction tube 1.

[0030] Reference Figure 1 The bottom end of the suction tube 1 is fixedly connected with a suction head 11, and the top end of the suction tube 1 is fixedly connected with a negative pressure ball 12. The air in the negative pressure ball 12 can be squeezed out by pressing to generate negative pressure, so that the sewage sample enters the suction tube 1.

[0031] Reference Figure 1-Figure 3The inner wall of the diverter ball 2 is fixedly connected to one end of the torsion spring 3. At this time, the torsion spring 3 is in the initial state. When the round tube 4 is rotated, the torsion spring 3 is compressed. The other end of the torsion spring 3 is fixedly connected to the outer wall of the round tube 4. The round tube 4 penetrates and is rotatably connected to the inner wall of the diverter ball 2. The inner wall of the right end of the round tube 4 is fixedly connected to one end of the reset spring 5. At this time, the reset spring 5 is in a stretched state. When the plug plate 6 is plugged into the outer wall notch of the diverter ball 2, the reset spring 5 will bring the plug plate 6 to reset. The other end of the spring 5 is fixedly connected to the right end of the plug plate 6, and the plug plate 6 is slidably connected to the inner wall of the circular tube 4. The plug plate 6 is plugged into the outer wall of the diverter ball 2. The outer wall of the diverter ball 2 is provided with a slot, which can be plugged with the plug plate 6 to limit the shielding ring 7. The fixing mechanism includes a splint 10, which is fixedly connected to the outer wall of the suction tube 1. The splint 10 is made of elastic material and can produce a certain deformation. The elasticity of the splint 10 is used to fix the sampling tube 9, and the sampling tube 9 is clamped on the inner wall of the splint 10.

[0032] Working principle: First, when sampling of the sewage pool is required, the nozzle of the suction tube 1 can be inserted into the pool. Since there is air in the suction tube 1 and the negative pressure ball 12, floating objects in the pool will not enter the suction tube 1 from the suction head 11. The lower end of the suction tube 1 can be completely inserted into the sewage pool. Then, the air in the negative pressure ball 12 and the suction tube 1 can be discharged by pressing the negative pressure ball 12. Then, the negative pressure ball 12 is released to generate negative pressure in the suction tube 1, and the sewage sample can enter the upper end of the suction tube 1 from the suction head 11. At this time, the sewage in the diversion ball 2 will slowly enter the sampling tube 9 from the connecting tube 8. Sampling: After the sampling is completed, press the negative pressure ball 12 again to discharge the residual water sample at the lower end of the suction tube 1 from the suction head 11. When sampling of the sewage pool in the next area is required, just rotate the circular tube 4 to rotate with the plug plate 6 and the shielding ring 7, and at the same time compress the torsion spring 3, so that the shielding ring 7 opens the connection between the diverter ball 2 and a group of connecting tubes 8. When the plug plate 6 and the grooves on the outer wall of the diverter ball 2 coincide, use the reverse elastic force of the reset spring 5 to reset the plug plate 6, so that the plug plate 6 and the outer wall groove of the diverter ball 2 are plugged in to complete the limit, and the shielding ring 7 closes the connection between the diverter ball 2 and the connecting tube 8 where the sampling has been completed.

[0033] When taking samples again, just follow the first step.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
