At this time, people can set the opening time of the solenoid valve 109 and the working time of the servo motor 131 and the stepper motor through the control panel 102. When the preset time arrives, the solenoid valve 109 opens, and the wastewater inside the wastewater pipeline enters the guide tube 117 through the connection port 107. At this time, the stepper motor starts to work, driving the rotating shaft 144 to rotate, and the rotating shaft 144 can drive the forcing wheel 115 to deflect, and the forcing wheel 115 can press the wear-resistant block 145 in contact with the bottom, so that the sliding tube 142 can be lowered. The pressure is applied so that the opening 147 on one side of the slide tube 142 can correspond to the internal channel of the guide tube 117, and the plugging portion 143 can be used to plug the upper opening 148 of the slide tube 142. At the same time, the ejector pin 141 at the bottom of the slide tube 142 is inserted into the one-way valve 149 on the top of the filter plate 152 for connection. At this time, the wastewater will enter the inner tube 151 inside the sample storage tube 110 through the slide tube 142 and the ejector pin 141 to achieve sampling. After the wastewater enters the inner tube 151, the filter plate 152 inside the inner tube 151 can filter the wastewater, so that large particles of floating objects in the wastewater can be separated, and the wastewater will fall into the lower part of the inner tube 151. In actual use, the servo motor 131 can drive the rotating shaft 128 is rotated, and the toothed disk 127 and the meshing fixed toothed ring 129 can be used to drive each fixed ring 119 to rotate through the rotating shaft 128. Each magnetic block 122 set on the rotating disk 133 can attract and cooperate with the magnetic block 2 157 at the bottom of the internal block 156 of the sample storage tube 110. The block 156 can drive the rotating rod 155 to rotate. The rotation of the rotating rod 155 and the stirring frame 153 can stir the wastewater, which can be beneficial to the subsequent sedimentation and stratification of the wastewater and facilitate the subsequent actual analysis work. The stirring frame 153 and the rotating rod 155 can attract fine iron filings in the wastewater, which is beneficial to further improve the separation degree of the wastewater, so that the wastewater sample can be directly separated into pure water samples after sampling. At the same time, the separated part can be synchronously stored separately inside the inner tube 151, which is beneficial to the comprehensive detection of wastewater. During the sampling process, when the rotating shaft 144 is driven to rotate one circle and complete a sampling, the rotating shaft 144 can drive the active bevel gear 112 to rotate synchronously, and the active bevel gear 112 can use the driven bevel gear 113 engaged at the bottom to drive the sleeve 135 to rotate synchronously, and the forcing plate 140 in the middle of the outer periphery of the sleeve 135 can drive the contacting slide 139 to slide along the guide frame 137, and the push plate 136 at the end of the slide 139 can push the sample storage tube 110 that has been sampled out of the card rack 120, so that the sample storage tube 110 can be pushed to the inside of the sample discharge tube 106,The sample tube 110 will slide down along the sample discharge tube 106 and be discharged from the housing 101. The magnetic coating on the inner side of the sample discharge tube 106 can repel the magnetic block 157 at the bottom of the block 156 in the sample tube 110, so that the sample tube 110 can slide down slowly, so that the sample tube 110 can be better protected. The reserved opening at the bottom of the sample discharge tube 106 can facilitate people to take the sample tube 110. At the same time, the sleeve 135 is driven by the rotating shaft 144 to rotate synchronously for one circle, completing the When a sample is taken out once, the driving gear 126 and the meshing driven gear 124 can be driven to rotate synchronously for one circle, and the driven gear 124 can drive the incomplete gear 121 to rotate through the fixed column 134, and the incomplete gear 121 can use the meshing driven gear ring 125 to drive the bracket 120 to deflect, so that the sample storage tube 110 with a sample on the bracket 120 can be rotated to the upper part of the next adjacent turntable 133, and the empty sample storage tube 110 can be rotated to the sampling position , waiting for the next sampling work, so that long-term continuous work can be achieved, which is conducive to long-term sampling and detection of wastewater pipes. After a single sampling is completed, the water pump will start working, and clean water can be pumped into the card interface 103 through the water pump. At this time, the sampling is completed, and the sliding pipe 142 will be reset under the drive of the elastic member 116, and the port 148 will be connected to the internal channel of the guide tube 117. The card interface 103 and the guide tube 117 can be connected through the port 148. The pressurization of port 103 can spray water into the inside of slide tube 142 and guide tube 117 to clean the inside of slide tube 142 and guide tube 117. The water inside guide tube 117 will be discharged from housing 101 through drain pipe 108, and part of the water discharged through ejector pin 141 will be discharged through the drain port at the bottom of housing 101. Backwashing of guide tube 117 and slide tube 142 can avoid residual wastewater from previous sampling affecting the accuracy of subsequent sampling, which is beneficial to practical use.
