Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy projects, in particular to a gate mechanism for sewage blocking in water conservancy projects. Background Art

[0002] In water conservancy projects, the gate mechanism used for sewage blocking usually refers to a device or equipment that prevents the flow of sewage. This mechanism is usually composed of one or more movable plate structures, which can control the opening and closing of water flow by lifting or rotating. When treating sewage, these gate mechanisms can be used to close pipes or channels to control or stop the flow of sewage, which helps prevent leakage, reduce pollution, and manage the allocation and utilization of water resources.

[0003] When sewage passes through the gate mechanism, some impurities in the sewage will adhere to the inner wall of the gate body. The attached impurities may gradually accumulate and form dirt, eventually causing partial or complete blockage of the gate mechanism, affecting normal operation. The impurities attached to the inner wall of the gate body will increase resistance and reduce the speed of water flowing through the gate mechanism, thereby affecting the operating efficiency of the system. Utility Model Content

[0004] The utility model aims to provide a gate mechanism for sewage plugging in water conservancy projects, which has the advantages of automatically cleaning the inner wall of the gate body, reducing the difficulty of cleaning, and solving the problem that impurities are easily accumulated on the inner wall of the gate mechanism.

[0009] Preferably, a positioning sleeve is installed on the top of the screw sleeve, and the positioning rod passes through the positioning sleeve. A stopper is installed on the end of the positioning rod away from the support plate, and a distance is left between the stopper and the baffle. The positioning rod limits the screw sleeve, and when the screw sleeve moves on the screw rod, the positioning sleeve moves on the positioning rod to prevent the screw sleeve from shaking.

The connecting pipe is connected to a pipeline for conveying sewage through the flange, and the sewage inside the gate body is discharged from the connecting pipe.

[0012] Preferably, the outer side of the scraper is in contact with the inner wall of the gate body. When the scraper moves, it can scrape off the impurities attached to the inner wall of the gate body.

[0013] Preferably, the gate body is welded with fixing plates on both the front and rear sides, and both fixing plates are provided with fixing holes. The gate body is fixed to the water outlet of the sewage treatment tank by using tools such as bolts through the fixing holes of the fixing plates.
