At the same time, the horizontal bars 301 and the vertical bars 302 arranged in an alternating manner on the drainage cover 3 can hold up large mud blocks and leaves, and the gaps between them do not affect the discharge of the accumulated water. The accumulated water is filtered through the first filter screen 2 inside the drainage barrel 1 and then discharged through the main drainage pipe 4. When the main drainage pipe 4 is blocked due to the accumulation of too much leaves and mud inside the first filter screen 2, the accumulated water rises inside the drainage barrel 1. When the accumulated water rises to the second water inlet position of the anti-blocking drainage pipe 5, it can be drained through the anti-blocking drainage pipe 5. When the anti-blocking drainage pipe 5 is draining, the water flow sensor 603 will sense the water flow, and then sound an alarm through the external alarm to notify the staff to clean the first filter screen 2. At the same time, the inside of the main drainage pipe 4 can also be cleaned through the sedimentation pipe 403.

[0030] To sum up, the utility model sets an anti-blocking drainage pipe 5 on the side of the drainage tube 1, so that the accumulated water can be discharged through the anti-blocking drainage pipe 5 when the main drainage pipe 4 is blocked, thereby avoiding the problem of the accumulated water being unable to be discharged due to the blockage of the drainage pipe; by setting a water flow sensor 603 in the anti-blocking drainage pipe 5, the water flow sensor 603 can be used to detect whether the anti-blocking drainage pipe 5 is enabled, and whether the main drainage pipe 4 is blocked can be timely understood, so that the staff can clean the drainage device in time.
