The rainwater flows into the drainage channel from the manhole cover, and the garbage is filtered by the main filter screen below. When there is too much garbage on the main filter screen, the spring is compressed downward, triggering the first inductor below, and transmitting the signal to the first alarm through the first transmission line, thereby solving the problem of inefficient filtering of garbage in rainwater.

[0004] However, the filter structure in the prior art cannot buffer and dissipate the high-speed water flow when the water flow increases and flows at high speed after the rainwater vertically enters the filter structure. A large amount of water flow falling on the filter screen will press the filter screen downward and compress the spring, triggering the inductor and thus causing false information (information of too much garbage on the filter screen).

[0012] Further, two rows of discharge ports are formed in the collecting box, and the discharge ports are rotatably connected with flaps.

[0013] Further, a locking mechanism is arranged between the flaps and the collecting box.

[0014] Further, the locking mechanism comprises first clamping grooves formed on both sides of the discharge ports and second clamping grooves formed on the flaps, and fixing members are clamped in the first clamping grooves and the second clamping grooves.

[0015] Further, the frame is provided with a chamfer.
