Unless otherwise indicated, the technical means used in the examples are conventional means well known to those skilled in the art.

Referring to fig. 1-5, the utility model discloses an automatic sampling device for sewage discharge, which comprises a drain pipe 1, a water pump 2 is arranged on the drain pipe 1, a water inlet pipe 3 is arranged on the water pump 2, a filter net bag 4 is arranged in the drain pipe 1 near the bottom of the drain pipe, the filter net bag 4 is a square filter frame enclosed by a partition net, the water inlet pipe 3 extends into the drain pipe 1 and the filter net bag 4, thereby filtering the sewage in the drain pipe 1 and avoiding impurities from being sucked into the water pump 2 through the water inlet pipe 3; certainly, in order to guarantee the filter effect, can set up the one deck filter screen on the mouth of pipe of inlet tube 3 to further filtration of sewage, seal between inlet tube 3 and the drain pipe 1, avoid sewage to spill from the gap between inlet tube 3 and the drain pipe 1. The water pump 2 is provided with a water outlet pipe 5, the other end of the water outlet pipe 5 extends into the filtering mechanism, the outlet end of the water outlet pipe is bent downwards, and the filtering mechanism is communicated with a sampler 7 through a pipeline 6. It should be noted that: the filtering net bag 4 is arranged in the drain pipe 1 and close to the bottom of the drain pipe, and mainly aims to collect sewage by the water pump 2 no matter how deep the sewage in the drain pipe 1 is.

Further, filtering component includes bottom open-ended cartridge filter 8, and in the drain pipe 1 was inserted to the bottom of cartridge filter 8, and sealed between the drain pipe 1, the bottom of cartridge filter 8 can be dismantled and be provided with movable chassis 9, is provided with the closed filter chamber 11 that encloses by filter screen 10 on the inner wall of cartridge filter 8, and pipeline 6 communicates with filter chamber 11. Filter screen 10's setting can carry out further filtration to sewage, and filter screen 10's mesh is less than the mesh of filtering string bag 4, the less impurity of filtration that can be further.

Further, the filter chamber 11 is arranged on the inner wall of the filter cartridge 8 near the top thereof, and the height of the filter chamber 11 is less than or equal to 1/2 of the height of the filter cartridge 8. Avoid sewage impurity suspension under the impulsive force of water pump 2 in sewage, and then enter into sampler 7 through pipeline 6, lead to tiny impurity too much in the water sample. And the filter chamber 11 is arranged at a higher position, when the water level of the sewage in the filter cylinder 8 is gradually increased, impurities can be partially precipitated in the process of water level increase, so that the solid impurities in the sewage in the final sampler 7 are less.

Furthermore, a plurality of guide posts 12 are arranged on the movable chassis 9 close to the edge of the movable chassis, guide grooves 13 for accommodating the guide posts 12 are formed in the bottom of the filter cartridge 8, springs 14 are sleeved on the guide posts 12, two ends of each spring 14 are fixed to the bottom of each guide groove 13 and the movable chassis 9 respectively, and the length of each guide groove 13 is larger than that of each guide post 12. It should be noted that: the spring 14 is arranged to enable the movable chassis 9 to move up and down at the bottom of the filter cartridge 8, i.e. to open or close the bottom of the filter cartridge 8, so that the sewage in the filter cartridge 8 is discharged into the drain pipe 1.

Further, in order to increase the flow guiding effect and enhance the acting force of the sewage pumped by the water pump 2 on impacting the movable chassis 9, a conical flow guiding block 15 is arranged at the center of the movable chassis 9, and the guide column 12 is arranged around the flow guiding block 15. The diameter of the bottom of the flow guide block 15 is smaller than that of the movable chassis 9. And a plurality of guide grooves 16 are arranged on the guide block 15, and the guide grooves 16 extend from the top of the guide block 15 along the inclined surface thereof towards the bottom. The outlet of the water outlet pipe 5 faces the top of the flow guide block 15. A plurality of water outlet holes 17 are arranged on the side wall of the filter cartridge 8 and close to the bottom of the filter cartridge. It should be noted that: when using cartridge filter 8, need control water pump 2's velocity of flow, use great velocity of flow at first, make activity chassis 9 move down under sewage strikes, make sewage leak to drain pipe 1 in from the gap between activity chassis 9 and the cartridge filter 8, then reduce the velocity of flow of water pump 2, make the impact force of its drainage can't strike away activity chassis 9, finally make sewage fill cartridge filter 8 gradually, at this moment, filter screen 10 filters sewage, enter into in sampler 7 through rose box 11 and pipeline 7. The water pump 2 and the liquid level sensor 19 are respectively and electrically connected with the PLC controller. The flow rate of the water pump 2 is controlled according to the size of the movable chassis 9 and the elastic force of the spring 14, which is not a fixed value. At the same time, the air in the filter cartridge 8 is discharged through the check valve 18 provided at the top of the filter cartridge 8. And a level sensor 19 inserted into the sampler 7 from the top of the sampler 7 monitors the level of wastewater in the sampler 7 in real time. When monitoring that the water level reaches the settlement position, PLC controller control water pump 2 closes, and the interior sewage of cartridge filter 8 then through apopore 17 flow to drain pipe 1 in can, the speed of apopore 17 discharge sewage is less than the speed that water pump 2 takes sewage into in the cartridge filter 8. When the water sample needs to be collected next time, the operation can be carried out by adopting the mode. Besides the first sampling, the later sampling, the sewage pumped into the filter cartridge 8 by the water pump 2 is flushed into the drain pipe 1 again from the movable chassis 9, and the substances left in the filter cartridge 8 after the last sampling are flushed into the drain pipe 1, so that the influence of the last sewage sample on the later sewage is avoided, and the final detection result is inaccurate.

In use the utility model discloses the time, only need to control the velocity of flow of 2 twice differences of water pump through the PLC controller, thereby make sewage to be detained in cartridge filter 8's sample or impurity wash in the inlet and outlet pipe 1 after sampling last time, gather this time sewage sample simultaneously, then filter through filter screen 10, finally automatic 6 inflow samplers 7 of pipeline through the slope setting, and level sensor 19 on the sampler 7 is the water level of sewage in real time monitoring sampler 7 then, after reacing the water level, PLC controller 19 then direct control water pump 2 closes, and the sewage in the cartridge filter 8 passes through apopore 17 and flows out, operating personnel only need take sampler 7 away take away go detect can, finally realize automatic sampling.
