Description

Technical Field

[0001] The utility model relates to the technical field of water supply and drainage pipelines, in particular to an anti-blocking pipeline structure for building water supply and drainage. Background Art

[0002] The water supply and drainage pipeline project is a pipe (channel) system project that transports and distributes industrial water supply and domestic drinking water, and collects, transports and discharges industrial wastewater, domestic sewage and rainwater. The water supply and drainage pipeline project is an integral part of the water supply and drainage system and plays an important role in the entire water supply and drainage system. It includes the pipe (channel) system itself and various structures on the pipe (channel) system (such as pumping stations, reservoirs, pipe bridges, gate wells, sewage inspection wells, rainwater inlets, etc.). The project investment accounts for the majority of the total investment in the water supply and drainage system project.

[0003] The patent application number is CN202320056048.9, which is a patent for preventing building water supply and drainage from blocking. Before installation, the sealing frame is placed in the placement groove. The filter net arranged on the sealing frame can intercept the sewage flowing into the water passage cavity of the building water supply and drainage, and filter the debris in the sewage to avoid subsequent pipe blockage. When the filter net needs to be removed for cleaning, hold the handle and rotate it in the opposite direction to move the L-shaped block upward until the L-shaped block is out of the positioning groove to separate the first flange from the second flange, remove the sealing frame and clean the filter net on the sealing frame, thereby avoiding pipe blockage.

[0004] In the above technology, the first flange and the second flange can be separated by holding the handle and rotating it in reverse to move the L-shaped block upward until the L-shaped block is out of the positioning groove, and the sealing frame is removed to clean the filter on the sealing frame. However, the steps for disassembling the filter are relatively cumbersome and not convenient enough. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides an anti-blocking pipeline structure for building water supply and drainage.

[0010] As a further improvement of the above solution, the surfaces of the fixing plate and the limiting ring are both provided with threads, and the surface of the fixing plate is threadedly connected to the inner wall of the first drainage pipe.

[0011] Through the above technical solution, the inner wall of the first drain pipe is provided with an internal thread that is compatible with the fixing plate and the limiting ring.

[0012] As a further improvement of the above scheme, the right end of the limiting ring is fixedly connected to the left end of the fixed plate, and the left end of the limiting ring is fixedly connected to a toggle rod. The number of the toggle rods is five, and the five toggle rods are distributed in a circle around the limiting ring. The surface of the toggle rod is provided with anti-slip grooves.

[0013] Through the above technical solution, it is more convenient to rotate the limit ring by using the toggle rod.

[0014] As a further improvement of the above solution, the number of the through holes is set to be several, and the through holes are distributed around the fixed plate in a circle, and the filter screen is located inside the first drainage pipe.

[0015] Through the above technical solution, the debris is initially filtered through a plurality of through holes, and the debris is secondarily filtered through the filter net, thereby reducing the debris from entering the first drainage pipe and the second drainage pipe.
