Description

Technical Field

[0001] This utility model relates to the field of water supply and drainage pipeline technology, and in particular to a connection structure for municipal water supply and drainage pipeline design. Background Technology

[0002] Municipal water supply and drainage pipeline systems, as a crucial component of urban infrastructure, play a vital role in transporting domestic water and discharging sewage and rainwater. During pipeline laying and construction, the design of the connection structures directly impacts the system's stability, sealing performance, and ease of maintenance. This system is of great significance for ensuring the normal operation of the city and improving the quality of life for residents.

[0003] Patent CN222377504U discloses a connection structure for municipal water supply and drainage pipelines. The interception net can intercept waste residue in the pipeline. The interception net consists of a main net unit and auxiliary net units on both sides. The auxiliary net units can be extended and retracted on the main net unit. When the interception net passes through the installation port, the auxiliary net units on both sides of the main net unit can be manually contracted to shrink the size of the interception net. When the interception net is installed inside the pipeline, the auxiliary net units on both sides of the main net unit extend away from the main net unit under the action of the extension spring, making the size of the interception net larger. At this time, the interception net fits the inner wall of the square pipe. However, the above-mentioned device has the following defects in use. In practical applications, fine waste residue in the pipeline may be deposited in the clearance gap of the lower frame used to avoid the auxiliary net body, as well as in the track groove of the inner wall of the square pipe, under the action of water flow. Long-term accumulation of this waste residue will cause blockage, which not only hinders the sliding of the lower frame and the C-shaped frame of the interception net in the track groove, but also causes the auxiliary net unit to be unable to extend or retract normally due to increased expansion and contraction resistance. In addition, when it is necessary to remove the interception net for cleaning, the deposited waste residue in the lower frame clearance and track groove may jam the interception net structure, making it difficult to remove it smoothly from the installation port, thereby affecting the maintenance efficiency of the pipeline system.

[0004] Therefore, how to easily disassemble the filter structure during cleaning operations has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content
