[0039] A water flow control device 8 for controlling the size of the drainage port of the manhole cover body 2 is arranged on the manhole cover body 2 of the present invention;

[0040] A monitoring device 9 for monitoring the status information of the manhole cover body 2 is arranged on the manhole cover body 2;

[0041] The water flow control device 8 includes an adjustment baffle 801 arranged at the drainage port position of the manhole cover body 2, the adjustment baffle 801 is used to block the size of the drainage port to achieve the control of the water flow, a rain sensor 802 is arranged on the manhole cover body 2, and a push rod motor 803 for controlling the movement of the adjustment baffle 801 is arranged on the manhole cover body 2, and the push rod motor 803 is communicatively connected to the rain sensor 802;

[0042] There are multiple drainage holes provided on the manhole cover body 2. The adjusting baffle 801 is movably arranged at the position of the drainage holes and can control the size of the drainage holes. When the rainfall is large, the rainfall sensor 802 acquires information and transmits a signal to the push rod motor 803. The push rod motor 803 controls the adjusting baffle 801 to open, increasing the drainage holes. When the rainfall is small, the adjusting baffle 801 is controlled to close the drainage holes to prevent blockage and reduce the entry of leaves, garbage, etc. into the sewer.
