[0042] Specific working principle:

[0043] The drainage trough body 1 is installed in a location where the municipal engineering is low-lying and prone to overflow;

[0044] After the rainwater is drained by the drainage strip 303 on the protective top cover 3, a drainage vortex is formed on the top of the drain plate 2 to speed up the drainage process of the rainwater;

[0045] After rainwater enters the gutter body 1, it is filtered by the filter screen 4 and discharged again through the outlet pipe 7;

[0046] Since a one-way limiting check plate 9 is provided at the outlet of the water outlet pipe 7, the outlet is blocked by the limiting strip 11, so that the check plate 9 can only move to one side of the limiting strip 11. At this time, the two check plates 9 are combined to block the outlet of the water outlet pipe 7. After the water hits the surface of the check plate 9, the check plate 9 moves to one side of the stop block 10, opening the outlet of the water outlet pipe 7 for drainage. Otherwise, it is closed by the impact of the water flow.

[0047] When the water level in the drainage trough body 1 rises, it contacts the overflow detection box 8. A leakage slot hole is opened on the side wall of the box body 802, so that water can enter the box body 802. The alarm control box 801 is also equipped with a lithium battery for powering the alarm control box 801. After the water level rises, the float 803 rises between the partition bars 804 and presses the switch of the alarm control box 801. Then, the municipal system receives the alarm signal and handles it in time.
