Detailed Description
The invention will be further explained with reference to the drawings and the specific embodiments.
Referring to fig. 1, a longitudinal sectional view of a concealed type multistage overflow drain port for a rainwater garden of the present invention is shown. Fig. 2 is a plan view of the concealed type multistage overflow drain port for a rainwater garden of the present invention. Referring to fig. 1 and 2, the present invention provides a concealed type multistage overflow drain port for a rainwater garden, including:
the well body 10 is vertically arranged on the rainwater garden, the bottom of the well body 10 is communicated with a municipal pipeline 20, the top of the well body 10 protrudes out of the ground 21 of the rainwater garden to form a protruding part, the top of the well body 10 is provided with a top opening, and the side part of the well body 10 is provided with a side opening;
the hidden structure 30 is arranged around the protruding part and is higher than the protruding part, the hidden structure 30 is provided with a through side channel 31, one end of the side channel 31 is communicated with the side port, and the other end of the side channel 31 is provided with an inlet;
a side grill 40 covering an inlet of the side passage 31;
a top grill 50 covering the top opening.
Specifically, the utility model discloses in the use, when the water level in the rainwater garden is lower, rainwater accessible side grid 40 filters and flows into in the well body 10 through the entry of side passageway 31, flows into municipal pipeline 20 through the well body 10 and realizes discharging. When the water level in the rainwater garden is high, rainwater can enter the well body 10 through a top opening formed in the top of the well body 10, impurities are filtered through the top grating 50 in the process, and the rainwater can also flow into the well body 10 through the inlet of the side channel 31 and flow into the municipal pipeline 20 through the well body 10 to be quickly discharged. The utility model discloses an above-mentioned structure carries out multilevel control, and carries out online sediment to rivers and purifies, obtains better play water quality of water.
As a preferred embodiment of the concealed type multi-stage overflow drain for rainwater garden of the present invention, the side view of the concealed type multi-stage overflow drain for rainwater garden of the present invention is shown in fig. 3.
