The direction of the notch of the water diversion groove 302 is consistent with the inclination direction of the horizontal plate 303, and the inclined plate 301 is inclined downward toward the middle position inside the water storage well 1. The two ends of the horizontal plate 303 are respectively fixedly connected to the inner wall of the water storage well 1 and the rotating shaft 304. The rotating shaft 304 is movably connected to the opening plate 305, and the sliding groove 307 is inclined. When the two opening plates 305 are closed, they are sealed, and the sliding groove 307 is directly facing the direction of the inclined plate 301.

[0018] According to the above embodiments, it should be noted that: in rainy weather, rainwater will drip into the water storage well 1 through the gap of the manhole cover 101, and the rainwater will first pass through the filter net 2. The filter net 2 filters and intercepts the rainwater mixed with leaves, stones, and branches to prevent impurities from entering the water storage well 1 and causing turbidity inside the water storage well 1, and to prevent impurities from clogging the connecting pipe 4 when the water pump 401 extracts water from the internal water storage well 1.

[0019] After passing through the filter screen 2, the rainwater will slide down along the inclined surface of the inclined plate 301, and the water diversion trough 302 will collect the rainwater. The water diversion trough 302 can also guide the flow direction of the collected rainwater, so that it flows to the inclined bottom end of the inclined plate 301 and drips downward onto the sliding groove 307 of the opening plate 305.

[0020] The design of the slope of the sliding groove 307 can collect smaller water flows, increase their weight on the opening plate 305, open the opening plate 305, collect water sources, improve collection efficiency, and avoid wasting smaller water sources.

[0021] When water source drops into the sliding groove 307, the opening plate 305 is forced to rotate along the rotating shaft 304, and the water source seeps; when there is no water source, the opening plate 305 is not subjected to force, and the opening plate 305 is reset under the action of the torsion spring 306 to seal the inside of the water storage well 1.

[0022] See also Figure 1-3As shown, a municipal rainwater storage device includes a well cover 101 provided at the top of the water storage well 1, a filter screen 2 is provided inside the water storage well 1 and at the bottom of the well cover 101, the filter screen 2 is movably connected to the water storage well 1, a water pump 401 is provided on one side of the bottom end of the water storage well 1, a connecting pipe 4 is connected between the water pump 401 and the water storage well 1, and the connecting pipe 4 is L-shaped.

[0023] According to the above embodiments, it should be noted that the manhole cover 101 and the filter screen 2 are both snap-fitted and connected to the water storage well 1, so that they can be easily disassembled for subsequent cleaning or replacement.

[0024] The connecting pipe 4 is arranged in an L shape, with one end of the L facing the bottom of the water storage well 1. The water pump 401 can better extract the water source inside the water storage well 1 and extract the water resources for use.

[0025] To sum up, the usage process of this device is as follows: in rainy weather, rainwater will drip into the water storage well 1 through the gap of the manhole cover 101, and the rainwater will first pass through the filter net 2. The filter net 2 filters and intercepts rainwater mixed with leaves, stones, and branches to prevent impurities from entering the water storage well 1 and causing turbidity inside the water storage well 1, and to prevent impurities from clogging the connecting pipe 4 when the water pump 401 draws water from the internal water source of the water storage well 1.

[0026] After passing through the filter screen 2, the rainwater will slide down along the inclined surface of the inclined plate 301, and the water diversion trough 302 will collect the rainwater. The water diversion trough 302 can also guide the flow direction of the collected rainwater, so that it flows to the inclined bottom end of the inclined plate 301 and drips downward onto the sliding groove 307 of the opening plate 305.

[0027] The design of the slope of the sliding groove 307 can collect smaller water flows, increase their weight on the opening plate 305, open the opening plate 305, collect water sources, improve collection efficiency, and avoid wasting smaller water sources.

[0028] When water source drops into the sliding groove 307, the opening plate 305 is forced to rotate along the rotating shaft 304, and the water source seeps; when there is no water source, the opening plate 305 is not subjected to force, and the opening plate 305 is reset under the action of the torsion spring 306 to seal the inside of the water storage well 1.

[0029] The well cover 101 and the filter screen 2 are both snap-fitted and connected to the water storage well 1, so they can be easily disassembled for subsequent cleaning or replacement.

[0030] The connecting pipe 4 is arranged in an L shape, with one end of the L facing the bottom of the water storage well 1. The water pump 401 can better extract the water source inside the water storage well 1 and extract the water resources for use.
