Municipal embedded type adjusting drainage device capable of preventing sundries from adhering and blocking

Abstract

The invention provides a municipal embedded type adjusting drainage device capable of preventing sundries from adhering and blocking, and relates to the technical field of municipal drainage devices.The problems that the drainage normality is easily affected by sundries due to the fact that sundries are easily accumulated on a filter screen in the using process, the sundries adhering to the filter screen are difficult to clean, and threads for transmission are easy to rust after being in contact with water for a long time are solved. The municipal embedded type adjusting drainage device capable of preventing sundries from adhering and blocking comprises a casing pipe; a sealing seat is welded to the casing pipe, a drainage pipe is sleeved with the casing pipe, and an adjusting structure is welded to the casing pipe. Due to the fact that a cutter is welded to the outer wall of the casing pipe, the cutter makes contact with a base plate when the drainage pipe slides rightwards by 10 cmalong the casing pipe, the sundries hung on the drainage pipe are in a shearing state at the moment, and therefore, the sundries connected to the drainage pipe in a sleeved mode can be automatically sheared and removed in the sealing process of the drainage pipe.

Description

Technical field [0001] The invention belongs to the technical field of municipal drainage devices, and more specifically, relates to a municipal pre-buried type regulating drainage device for preventing adhering and blocking of debris. Background technique [0002] With the development of society, more and more roads are being built, and most of the pipeline drainage devices are installed under the roads, and these drainage devices are equipped with faucets for switching. [0003] For example, application number: CN201711463946.1, the present invention discloses a drainage device for municipal roads, which includes a road main body and an isolation pipe. The road main body is provided with a drainage pipe, and the road main body is provided with a drainage well. The top of the well is connected to the road surface of the main body of the road, and the bottom end of the drainage well is connected to the drainage pipe. A fixing plate is installed at the bottom end of the drainage wel...

AI Technical Summary

Problems solved by technology

[0007] In order to solve the above-mentioned technical problems, the present invention provides a municipal pre-embedded anti-dirty clogging regulating drainage device to solve the existing problem that the filter screen of the existing device is easy to accumulate sundries during use, and these sundries The debris easily affects the normality of drainage, and it is difficult to clean up the debris adhering to the filter net. It is impossible to automatically clean the debris on the filter net and automatically cut the debris through structural improvements while switching the valve. Clearly; moreover, most of the existing switching valves are driven by threads, and the threads used for these transmissions are prone to rust in long-term contact with water and affect normal adjustment.
