[0003] Publication No. CN212534396U discloses a water supply and drainage structure for fire fighting in building pipelines. The device can crush larger dirt flowing in the drainage pipe by setting a crushing mechanism and a driving motor, and use the driving motor to realize the rotation of the crushing knife, so as to avoid the dirt from gathering together and blocking the main drainage pipe, so as to facilitate the normal sewage discharge of residents. The protection mechanism and the sealing mechanism are set to achieve a protective effect, effectively preventing the dirt from being twisted into the connection between the rotating rod and the mounting seat and the connection between the rotating rod and the output shaft of the driving motor, which affects the normal operation of the rotating rod, and can ensure the sealing effect between the protective plate and the rotating rod, so as to prevent the water flow from penetrating into the interior of the protective plate.

[0017] 2. The rotation of the rotating rod drives the rotation of the crushing knife, and the rotation of the crushing knife crushes the blockage. When encountering a harder blockage, the crushing knife contacts the blockage, and then drives the ladder block to slide inside the slide slot through the connecting block.
