The shaft seat 20 is fixedly connected by bolts and fixedly mounted on the output end of the reduction motor 5. A telescopic tube 8 is movably mounted on one side of the guide tube 6 relative to the shunt tube 3. A first connecting ball seat 9 is movably mounted on the side of the telescopic tube 8 opposite to the guide tube 6. A peristaltic pump 10 is fixedly mounted on one side of the sampling box 1. A water inlet end 11 and a water outlet end 12 are fixedly mounted on the front side of the peristaltic pump 10 respectively. One end of the water inlet end 11 is fixedly connected with a connecting pipe and extends to the sewage treatment equipment. The peristaltic pump 10 is electrically connected to an external main controller through a connecting line. With the cooperation of two semicircular limit plates 7 and the shaft seat 20, the reduction motor 5 can drive the semicircular limit plate 7 to adjust the angle, thereby facilitating the docking of one side of the telescopic tube 8 with different second connecting ball seats 13.

[0026] like Figure 2-Figure 3As shown, a second connecting ball seat 13 is fixedly installed on one side of the shunt tube 3, a connecting groove 14 is opened on one side of the second connecting ball seat 13, and the outer surface of the second connecting ball seat 13 is coated with a rubber layer, one side of the shunt tube 3 away from the second connecting ball seat 13 is connected to the wastewater treatment equipment through a connecting pipe, and the other side of the shunt tube 3 away from the second connecting ball seat 13 is connected to the detection equipment through a connecting pipe, and two groups of shunt tubes 3 and second connecting ball seats 13 are arranged on the inner side of the sampling box 1, which facilitates the docking of one side of the telescopic tube 8 with the corresponding second connecting ball seat 13, thereby realizing the functions of sewage sampling and water discharge in the pipeline.

[0027] like Figure 2-Figure 6 As shown, a fixing ring 15 is fixedly installed on one side of the guide tube 6, and a sealing groove 16 is provided on one side of the fixing ring 15. The side of the guide tube 6 away from the fixing ring 15 is movably connected to one end of the water outlet end 12 through a connecting pipe. A sealing ring 17 is fixedly installed on one side of the telescopic tube 8. A screw groove 18 is provided on one side of the first connecting ball seat 9. The first connecting ball seat 9 is threadedly connected to one side of the telescopic tube 8 through the screw groove 18. The outer surface of the first connecting ball seat 9 is coated with a rubber layer, and the inner channel of the first connecting ball seat 9 is connected to the telescopic tube 8. The telescopic tube 8 is connected through the sealing ring 1 7 is inserted and installed on the guide tube 6, and one side of the sealing ring 17 is inserted and connected in the sealing groove 16. The guide tube 6 located between the semicircular limit plate 7 and the telescopic tube 8 is sleeved with a compression spring 21. The compression spring 21 applies a certain supporting force to the telescopic tube 8, so that when the guide tube 6 drives the telescopic tube 8 and the first connecting ball seat 9 to change the angle, the first connecting ball seat 9 can be squeezed and retracted on the side of the corresponding second connecting ball seat 13, so that one side of the first connecting ball seat 9 can be inserted into the corresponding connecting groove 14.

[0028] It should be noted that the utility model is a sampling device for wastewater treatment and detection. When the wastewater is sampled, one side of the first connecting ball seat 9 is inserted and connected in the connecting groove 14 of one of the second connecting ball seats 13, and the peristaltic pump 10 can be started by the external main controller, so that the water inlet end 11 of the peristaltic pump 10 cooperates with the connecting pipe to extract the wastewater. At this time, since the connecting pipe connected to the side of the water inlet end 11 still has the wastewater retained in the last detection, the wastewater in the connecting pipe on the side of the water inlet end 11 will be discharged into the guide pipe 6 through the water outlet end 12 and the connecting pipe, and discharged into the corresponding diversion pipe 3 through the guide pipe 6 and the first connecting ball seat 9 and then discharged into the wastewater treatment equipment again;

[0029] After the residual waste water in the connecting pipe on the side of the water inlet end 11 is discharged, the peristaltic pump 10 pauses for a few seconds. At this time, the reduction motor 5 is started, and the output end of the reduction motor 5 drives the shaft seat 20 to rotate a certain angle, so that the shaft seat 20 cooperates with the two semicircular limit plates 7 to drive the guide tube 6 to rotate a certain angle, so that the guide tube 6 drives the telescopic tube 8 and the first connecting ball seat 9 to rotate synchronously. As a result, one side of the first connecting ball seat 9 is deflected and displaced in the connecting groove 14 corresponding to the second connecting ball seat 13, so that the first connecting ball seat 9 is affected by the change of the groove body structure in the connecting groove 14 and moves toward the semicircular limit plate 7 side, so that the first connecting ball seat 9 drives the telescopic tube 8 to move on the guide tube 6, and the telescopic tube 8 compresses the compression spring 21 toward the side of the two semicircular limit plates 7, so that The first connecting ball seat 9 is disengaged from one of the connecting grooves 14, and then, as the guide tube 6 drives the telescopic tube 8 and the first connecting ball seat 9 to continue to rotate, one side of the first connecting ball seat 9 can be made to contact with another second connecting ball seat 13, and similarly, the first connecting ball seat 9 continues to rotate and is displaced by the limitation of the outer surface of the current second connecting ball seat 13. When one side of the first connecting ball seat 9 moves into its connecting groove 14, the telescopic tube 8 is pushed to one side with the help of the extension and rebound characteristics of the compression spring 21. Then, the telescopic tube 8 drives one side of the first connecting ball seat 9 to be inserted into the connecting groove 14 on the required side of the second connecting ball seat 13, and then, the peristaltic pump 10 is started again, and the sewage can be pumped into another diversion pipe 3, and the connecting pipe transports the sewage to the detection equipment.
