After sampling by sampling device, sewage cylinder is placed below sample outlet pipe, and the valve of water pipe is opened to flush sampling pipe and sampling device, and sewage flows into sewage cylinder below sample outlet pipe.

[0003] Sewage cylinder is located below sample outlet pipe, and sewage sample outlet pipe falls into sewage cylinder, and part of sewage falls outside sewage cylinder due to the difference between them, causing pollution of production environment, so a kind of sample pipeline self-cleaning sampling device is needed to solve the above problems. UTILITY MODEL CONTENT

[0004] The utility model aims at providing a kind of sample pipeline self-cleaning sampling device to solve the problem of sewage cylinder being located below sample outlet pipe, sewage sample outlet pipe falling into sewage cylinder, and part of sewage falling outside sewage cylinder due to the difference between them, causing pollution of production environment.

[0005] To solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model is a kind of sample pipeline self-cleaning sampling device, comprising:

[0007] Sampling assembly, the sampling assembly includes sampling pipe and sample outlet pipe, one end of the sampling pipe is welded outside the tank body of external equipment, the sample outlet pipe is welded in the middle segment of sampling pipe, and is in inclined state;

[0008] Anti-pollution assembly, the anti-pollution assembly includes connecting shaft, torsional spring, receiving box, connecting pipe and hose, the connecting shaft is fixed outside the lower segment of sample outlet pipe, the torsional spring is sleeved on the connecting shaft, the receiving box is rotatably connected at one end of the connecting shaft on the upper end side, the connecting pipe is welded on the lower surface middle part of receiving box, and is communicated with receiving box, the upper end of hose is sleeved on the lower end of connecting pipe.

[0009] Further, the anti-pollution assembly further includes clamp and fixed block, the clamp is sleeved on the middle segment of sample outlet pipe, the fixed block is welded on the side of clamp, and the connecting shaft is fixed on both sides of fixed block.

[0010] Further, the receiving box is wrapped around the lower end of sample outlet pipe, and the connecting pipe is located directly below the mouth of sample outlet pipe.

[0011] Furthermore, the sampling assembly also includes valves, water pipes, and a sampler. The water pipe is welded to the middle section of the sampling tube, the valves are fixed to one end of the sampling tube near the external equipment and the lower end of the water pipe, and the sampler is connected to the other end of the sampling tube via a flange.

[0012] Furthermore, it also includes a stabilizing component, which includes an L-shaped connecting plate and a limiting hole. The upper end of the L-shaped connecting plate is fixed to the side of the clamp, and the limiting hole is opened at the upper end of the side of the receiving box.

[0013] Furthermore, the stabilizing component also includes a through hole, a rotating shaft, and a limiting plate. The through hole is opened at one end of the L-shaped connecting plate, one end of the rotating shaft is fixed in the through hole, one end of the limiting plate is fixed to the other end of the rotating shaft, and the other end of the limiting plate is inserted into the through hole.

[0014] Compared with existing technologies, the advantages of this utility model are:

[0015] I. This utility model, through its anti-fouling component, allows for the following operation: When sampling is required, the sampling box opening is placed on the upper side of the receiving box, and the receiving box is pressed down, causing it to rotate around the connecting shaft until the sampling box is completely below the sample outlet tube. After sampling, the valve on the sampling tube is closed, and the sampling box is removed. The receiving box, freed from the pressure of the hand, rotates in the opposite direction around the connecting shaft under the action of the torsion spring, returning to the lower end of the sample outlet tube. When the valve on the water pipe is opened after sampling, clean water flows out of the water pipe to clean the sampling tube, sample outlet tube, and sampler. Wastewater flows into the receiving box and then flows from the connecting pipe and hose into the wastewater tank. This design prevents wastewater from spraying outside the wastewater tank and causing environmental pollution.

[0016] II. This utility model, through the setting of a stabilizing component, pushes the limiting plate in the limiting hole upward during sampling, causing it to rotate upward and move out of the limiting hole. Then, it rotates downward to open the receiving box. After sampling, under the action of the torsion spring, the receiving box reverses. When the upper end of one side of the receiving box rotates to the limiting plate, it pushes the limiting plate upward, causing the limiting plate to rotate upward around the rotating axis in the through hole. When the receiving box returns to its original position, the limiting plate is completely located inside the receiving box and falls downward under the action of gravity. The end away from the rotating axis falls into the limiting hole, making the receiving box unable to move downward. This setting can avoid the instability of the receiving box caused by the impact of water flow when sewage falls into the receiving box during cleaning. Attached Figure Description

[0032] The anti-fouling assembly further comprises a clamp 20 and a fixing block 21. The clamp 20 is sleeved on the middle section of the sample outlet pipe 11. The fixing block 21 is welded to the side of the clamp 20. The connecting shaft 22 is fixed to the two sides of the fixing block 21.

[0033] The receiving box 24 is wrapped around the lower end of the sample outlet pipe 11. The connecting pipe 25 is located directly below the mouth of the sample outlet pipe 11.
