The purpose of this utility model is achieved through the following technical solutions, negative pressure suction type increases row's catch basin cover automatically, comprise the inlet opening on catch basin cover and catch basin cover, bottom, inlet opening is provided with negative pressure and produces frame, doubly, water inlet edge, inlet opening is right angle for the height of negative pressure generation frame and the 3-4 that inlet opening degree of depth sum is inlet opening width.
A kind of above-mentioned negative pressure suction type increases the method that row's catch basin cover increases row's rainwater automatically, comprise by the inlet opening on catch basin cover and discharge surface gathered water, the 3-4 that the catch basin cover inlet opening degree of depth is increased to inlet opening width doubly, when catch basin cover is flooded by ponding, ponding forms vertical water outflowing jet by inlet opening, ponding forms necked-down section in inlet opening, the formation negative pressuren zone, edge, inlet opening at necked-down section place, and the vacuum that negative pressuren zone produces increases inlet opening displacement automatically; By by edge, inlet opening right angle, increase the vacuum of negative pressuren zone, further increase surface drainage amount.
Further, the described 3-4 that the catch basin cover inlet opening degree of depth is increased to inlet opening width is doubly by arranging the realization of negative pressure generation frame in bottom, inlet opening.
Compared with prior art, the utlity model has following beneficial effect:
First, owing to opening an aperture on the container side wall of liquid filling, liquid particle, under certain head effect, flows to aperture from all directions, and flows out with jet state, due to fluid inertia effect, behind the aperture of flowing through, section shrinks phenomenon, apart from d/2 place, aperture, is reaching minimum value, it is parallel that streamline is tending towards, and forms necked-down section.If fill the short tube of one section of L=(3-4) d on aperture, just now the flow phenomenon that goes out of current is vertical water outflowing jet.When liquid stream process ozzle, in ozzle import department, liquid stream still has shrinkage phenomenon, makes the flow velocity of necked-down section be greater than exit velocity.Therefore the moving hydraulic pressure at ozzle necked-down section place must be less than atmospheric pressure by force, forms vacuum (negative pressure) in ozzle, and its vacuum is about p
v=0.75H
0, the existence of vacuum has been equivalent to increase the acting head of ozzle.Under identical acting head, the conveyance capacity of same section ozzle is 1.32 times of aperture conveyance capacity.So the utility model uses the catch-basin cover plate new structure of hydraulics vertical water outflowing jet principle design, can automatically form water inlet ozzle influent stream according to surface gathered water amount and in catch-basin cover plate place influent stream situation, negative pressure suction type increases surface drainage.
The second, the utility model makes the easy to maintenance of Pluvial catch-basin draining; Corollary apparatus is simple and easy, can on existing catch-basin, use, and without catch-basin is transformed, the use that greatly facilitates utility model is promoted.

The specific embodiment
As shown in Figure 4,5, 6, a kind of negative pressure suction type increases row's catch basin cover automatically, the inlet opening 2 that comprises catch basin cover 1 and catch basin cover, bottom, inlet opening is provided with negative pressure and produces frame 6, doubly, water inlet edge, inlet opening is right angle for the height of negative pressure generation frame and the 3-4 that inlet opening degree of depth sum is inlet opening width.
A kind of negative pressure suction type that utilizes increases the method that row's catch basin cover increases row's rainwater automatically, comprise by the inlet opening on catch basin cover and discharge surface gathered water, the 3-4 that the catch basin cover inlet opening degree of depth is increased to inlet opening width doubly, when catch basin cover is flooded by ponding, ponding forms vertical water outflowing jet by inlet opening, ponding forms necked-down section in inlet opening, the formation negative pressuren zone, edge, inlet opening at necked-down section place, and the vacuum that negative pressuren zone produces increases inlet opening displacement automatically; By by water inlet edge, inlet opening right angle, increase the vacuum of negative pressuren zone, further increase surface drainage amount.
Due to the negative pressure of inlet opening bottom produce frame 6 height and inlet opening degree of depth sum be inlet opening width 3-4 doubly, when on catch-basin cover plate, ponding 3 forms submerge discharging flow, on catch-basin cover plate, ponding 3 forms vertical water outflowing jet by inlet opening, ponding forms necked-down section in inlet opening, the formation negative pressuren zone, edge, inlet opening 5 at necked-down section place, the vacuum that negative pressuren zone produces increases rainwater 4 displacement of letting out under inlet opening automatically; By by water inlet edge, inlet opening right angle, increase the vacuum of negative pressuren zone, further increase surface drainage amount; When surface gathered water reduces, when water inlet is free style influent stream, negative pressuren zone disappears, and forms aperture influent stream.
Because open an aperture on the container side wall of liquid filling, liquid particle is under certain head effect, from all directions, flow to aperture, and flow out with jet state, due to fluid inertia effect, behind the aperture of flowing through, section shrinks phenomenon, apart from d/2 place, aperture, reaching minimum value, it is parallel that streamline is tending towards, and forms necked-down section.If fill the short tube of one section of L=(3-4) d on aperture, just now the flow phenomenon that goes out of current is vertical water outflowing jet.When liquid stream process ozzle, in ozzle import department, liquid stream still has shrinkage phenomenon, makes the flow velocity of necked-down section be greater than exit velocity.Therefore the moving hydraulic pressure at ozzle necked-down section place must be less than atmospheric pressure by force, forms vacuum (negative pressure) in ozzle, and its vacuum is about p
v=0.75H
