[0021] The present invention provides a municipal pipeline water environment detector, which has the following beneficial effects:

[0022] (1) By setting the displacement device, since the device is installed at the mouth of the municipal pipeline for a long time, the water in the municipal pipeline is detected in real time. The water flow in the municipal pipeline varies greatly. In order to reduce the pressure generated by the detection end and the water flow in the municipal pipeline, the air pump is used to inflate the air in the inflation tube, and the air pressure flows into the hollow cylindrical sleeve. In this way, the air pressure in the hollow cylindrical sleeve increases. At this time, the volume of the annular airbag gradually increases. In this way, the connecting plate can lift the outer shell of the detection device under the action of the annular airbag. As the water level rises, the connecting plate can lift the detection device shell, so that the detection end can be located in the middle and upper part of the water flow, thereby reducing the situation where the detection end is over-pressurized or hit by the gravel and sand device and sediment in the water, thereby ensuring the safety of the detection end and ensuring the service life of the detection end.

[0023] (2) By using the sampling device, when it is necessary to test the municipal pipe water, start the water pump, so that the bottom end of the detection end and the water contact end of the water administration pipe form a negative pressure state. After the detection end draws the sampled water sample into the detection end, the detection end detects the water sample. In this process, since the detection end needs to be regularly maintained, a transfer sealing sleeve is arranged between the suction pipe and the detection end. When the driving device drives the detection end to rotate, the driving device drives the rotating sealing sleeve to rotate. At this time, the sealing ring 2 on the rotating sealing sleeve rotates in the hollow cavity set in the fixed sealing sleeve. Due to the provision of the limited position slip ring and the sealing ring 1, during the rotation, it is always possible to ensure that a sealing area is formed between the fixed sealing sleeve and the rotating sealing sleeve, which is conducive to the extraction of samples. Moreover, when the detection end is cleaned regularly, it can ensure that the detection end can rotate independently, thereby ensuring the flexibility of the detection device.

[0024] (3) When cleaning the detection end, the guide rod provided on the detection end contacts the guide plate. The guide plate can squeeze the guide rod into the guide groove and make the guide rod completely located in the guide groove. In this way, the telescopic end of the detection end will move inward. In this way, the water stains on the telescopic end can be scraped off and concentrated at the end of the detection end under the action of the sealing sleeve. At this time, when the water stains on the end of the detection end pass through the detection device housing, the surface is first scrubbed with a cleaning brush, and then the stains on the surface of the detection end are thoroughly cleaned with a soft bristle board and a rag. Clean thoroughly. During this process, since three arc-shaped wave strips are arranged on the inner wall of the cleaning brush, soft-bristle board and rag area, when the wave surface of the arc-shaped wave strip contacts the surface of the detection end, due to the vibration, the cleaning brush, soft-bristle board and rag area vibrate in the arc-shaped groove in cooperation with the compression spring, which is helpful for the later treatment of dry mud remaining on the cleaning brush, soft-bristle board and rag area. This can not only remove the stains on the surface of the detection end, but also can treat the stains remaining on the cleaning brush, soft-bristle board and rag area after the detection end is cleaned.

[0025] (4) By setting the detection end, when the detection end is in operation, under the elastic action of the extrusion spring, the bottom of the sealing plug can be pressed against the inner cavity of the sealing sleeve, so that the sealing sleeve can be in a closed state, and the sealing plug can effectively seal the water outlet, so that the hollow column is in a negative pressure state, and then the bottom of the water inlet pipe can be in a negative pressure state, so that the sampled water can enter the detection sleeve from the water inlet pipe, and the isolation filter cloth isolates the sludge in the water, thereby completing the sampling operation, and under the action of the detector, the water sample is tested. When the detection end is cleaned, the guide rod can move the sampling tube inward, so that the sampling tube moves into the sealing sleeve, and the sealing sleeve can scrape off the sludge on the sampling tube. At this time, the sealing plug on the sampling tube can be separated from the sealing state at the water outlet, and then the water in the detection sleeve that has completed the test can be discharged from the water outlet through the sampling tube. After the test is completed, the sample water after the test can be quickly processed.

The advantage of this installation is that it can quickly locate the pollution emission source in the branch pipeline, thereby quickly and effectively achieving the purpose of containment. It does not require manual operation, reduces workload, and improves detection efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] By setting the detection end 18, when the detection end 18 is in operation, under the elastic action of the extrusion spring 55, the bottom of the sealing slide 56 can be pressed against the inner cavity of the sealing sleeve 28, so that the sealing sleeve 28 can be in a closed state, and the sealing slide 56 can effectively seal the water outlet 52, so that the hollow column 27 is in a negative pressure state, and then the bottom end of the water inlet pipe 50 can be in a negative pressure state, so that the sampled water can enter the detection sleeve 49 from the water inlet pipe 50, and the isolation filter cloth 48 isolates the sludge in the water, thereby completing the sampling. The sampling operation is performed, and under the action of the detector 53, the water sample is tested. When the detection end 18 is cleaned, the guide rod can move the sampling tube 29 inward, so that the sampling tube 29 moves into the sealing sleeve 28, and the sealing sleeve 28 can scrape off the sludge on the sampling tube 29. At this time, the sealing slide plug 56 on the sampling tube 29 can be separated from the sealing state at the water outlet trough 52, and then the water that has been tested in the detection sleeve 49 can be discharged from the water outlet trough 52 through the sampling tube 29. In this way, the sample water after the test is completed can be quickly processed.

[0048] Of course, in actual operation, the device is also provided with a control terminal for real-time feedback of detection data, so that the control terminal can quickly feed back the detection data of the water source to the municipal management department, so that the situation of the polluted water at the detection point of the device can be understood in real time, and can be dealt with in time.
