Automatic sewage disposal anti-blocking mechanism for drainage U-shaped pipe

FU XIAN'AN

The invention relates to the technical field of drainage pipeline systems, and discloses an automatic sewage disposal anti-blocking mechanism for a drainage U-shaped pipe. The automatic sewage disposal anti-blocking mechanism comprises a U-shaped pipe main body. A connecting snap ring is arranged at a bend in the U-shaped pipe main body, and one side of the outer surface of the connecting snap ring is fixedly sleeved with a sealing piston II. The outer surface of a sealing piston I and the outer surface of the sealing piston II are in friction contact with the interior of the U-shaped pipe main body. According to the automatic sewage disposal anti-blocking mechanism for the drainage U-shaped pipe, the automatic sewage disposal anti-blocking mechanism is fixed to a certain position throughelastic force of a reset spring so as to block a channel between the U-shaped pipe main body and a sewage discharge pipeline, a linkage mechanism is triggered through buoyancy of a floater when the automatic sewage disposal anti-blocking mechanism is blocked so that the U-shaped pipe main body and the sewage discharge pipeline can be communicated with each other, and solid sediments at the bottomof the inner cavity of the U-shaped pipe main body are automatically discharged into a drainage pipeline system. Manual operation is not needed in the whole process, the phenomenon of waste water leakage is avoided, and stability and reliability are high.

本发明涉及排水管路系统技术领域，且公开了一种用于排水U型管的自动清污防堵机构，包括U型管主体，所述U型管主体内部的弯道处设有连接卡环，且连接卡环外表面的一侧固定套接有密封活塞Ⅱ，所述密封活塞Ⅰ和密封活塞Ⅱ的外表面均与U型管主体的内部摩擦接触。该用于排水U型管的自动清污防堵机构，并通过复位弹簧的弹力将其固定在一定的位置上以封堵U型管主体与排污管道之间的通道，并在其发生堵塞时利用浮子的浮力触发上述联动机构使得U型管主体与排污管道之间相互连通，以将U型管主体内腔底部的固体沉积物自动排送到排水管道系统中，整个过程中无需人为的操作且不会发生废水泄漏的现象，稳定性及可靠性较高。
