Please refer to the turbine rain perforaled strainer structural representation shown in Fig. 1, turbine rainwater bamboo comb of the present invention comprises: framework 1, many arc castor bars 2 and draining bridge 3.Framework 1 is circular or oval framework, for supporting total, considers that circle is more firm than ellipse, and stress deformation is less, circular framework;
Many arc castor bars 2, all arc castor bars order centered by framework center is lined up turbine-like, between adjacent two arc castor bars, has drainage gap, the seam 7 of combing, the outer end of all arc castor bars is connected in framework 1, and the inner end of all arc castor bars is fixedly linked; On every arc castor bar, offer a plurality of drain holes 4;
Shown in draining bridge 3(Fig. 2 and Fig. 3), be crossed on and comb on seam 7, draining bridge 3 and the seam 7 of combing are corresponding one by one, offer respectively a plurality of draining breach 5 on the two side of draining bridge, the bottom of draining breach is concordant with the surface of arc castor bar, and current stitch 7 through draining breach 5 by comb and flow into drainage.For ease of illustrating, understand clearly, a draining bridge is only shown in Fig. 1, actually should be every comb and sew on all across being provided with a draining bridge 3.
The present invention adopts the double-edged fine-toothed comb structure of turbine-like, makes current in flow process, form eddy-currents, and eddy-currents can be accelerated the flow velocity of water.According to hydraulic principle, the foreign material in current are because centrifugal force and Action of Gravity Field, in current the floating thing of lighter weight as leaf etc. can be pooled to eddy-currents periphery with current not stop and rotation until current are emptied completely, avoid its deposition to stop up to double-edged fine-toothed comb.And the heavier impurity of quality can be assembled to eddy-currents center and flow into drainages through drain hole 4, the seam 7 of combing in this process as the grains of sand etc.Even to cross bigger material too much because of discharge, cause the drain hole 4 on arc castor bar 2 to stop up, current also can stitch 7 inflow drainages by comb via 3 draining breach 5 on draining bridge.
Because this device is less the closer to central area drain hole 4 and draining breach 5, the seam 7 of combing is thinner, so draining sectional area is also less.When discharge is excessive, can cause the catchment area at double-edged fine-toothed comb middle part to increase, water level rise cannot form eddy-currents until form a whole water surface.Institute thinks that generation eddy-currents is to guarantee draining flow velocity, draining bridge 3 is designed to domes (shown in Fig. 2 and Fig. 3), it is from increasing highly gradually outside to inside, while closing on double-edged fine-toothed comb center, form vault, highly decline afterwards, by the poor formation eddy-currents of height of water level at vault and double-edged fine-toothed comb center, thereby guarantee draining flow velocity.
The bridge floor of draining bridge 3 is provided with row's projection 31.When current reduce, the flow velocity of eddy-currents reduces, and floating thing deposits gradually, and projection 31 can be by floating thing backstop therein on one or a few draining bridge 3, and remaining draining bridge still can guarantee normal draining.
A disk 6 is established at the center of turbine rain perforaled strainer, and the inner end of all arc castor bars 2 is all connected with the circumference of disk 6.It is poor that the arranging of disk 6 can further increase the height of water level at the above-mentioned vault of mentioning and double-edged fine-toothed comb center.Arc castor bar, from being tapered outside to inside, arranges the bearing strength that disk 6 also contributes to increase framework central region simultaneously.On disk 6, also offer a plurality of drain holes 4 for draining.
Radical, the width of arc castor bar 2, the number of drain hole 4 and draining breach 5, size should be according to practical application, the size of inlet for stom water etc. is specifically considered setting, as the castor bar that is applied to the rain perforaled strainer of biotope can arrange less and wide, and that application and the castor bar of rain perforaled strainer on road can arrange is many and thin.The radical of arc castor bar is generally limited to 5-50 root, and drain hole and draining breach are done corresponding adjustment according to the number of castor bar.Drain hole is square hole, circular hole or polygon hole, and for example in the present embodiment, the drain hole on arc castor bar 4 is circular, and draining breach on draining bridge is irregular hole shape.The hole shape setting principle of drain hole and draining breach is should be large as far as possible in the situation that guaranteeing bearing strength, to guarantee drain discharge.
The concrete economic budget of material basis of turbine rain perforaled strainer and applied environment are selected has high strength and corrosion resistant plastics, metal or fibrous concrete etc.According to preferred embodiment, but also nonessential, turbine rain perforaled strainer is one-body molded by mould, also can make respectively framework 1, arc castor bar 2, draining bridge 3, then it is integrally welded or other connected mode is spliced into one, as bayonet socket, draw-in groove are set are used for clamping.
In sum, the present invention adopts the double-edged fine-toothed comb structure of turbine-like, makes current produce eddy-currents and accelerates flow velocity.Effectively different foreign material in separated flow, and the combination that adopts drain hole, draining breach and comb to stitch have solved the blockage problem of double-edged fine-toothed comb when assurance displacement is set.This device does not limit and is applied to road drainage system, all need to filter foreign material and draining equipment all can apply this device.So the present invention has effectively overcome various shortcoming of the prior art and tool high industrial utilization.
Above-described embodiment is illustrative principle of the present invention and effect thereof only, but not for limiting the present invention.Any person skilled in the art scholar all can, under spirit of the present invention and category, modify or change above-described embodiment.Therefore, such as in affiliated technical field, have and conventionally know that the knowledgeable, not departing from all equivalence modifications that complete under disclosed spirit and technological thought or changing, must be contained by claim of the present invention.
