Embodiment mono-:
Please refer to the square cubic rain perforaled strainer structural representation shown in Fig. 1, square cubic rain perforaled strainer of the present invention consists of one or more square drain module, and drain module adopts square structure to adapt to conventional inlet for stom water.Drain module comprises:
Many arc castor bars 1, all arc castor bars stretch out from drain module center, and the inner, the outer end of all arc castor bars are fixedly linked respectively, all arc castor bars are divided into two groups, two groups distribute about described drain module Central Symmetry, the bending direction of arc castor bar is consistent on the same group, and the bending direction of two groups of arc castor bars is identical or contrary; Between adjacent two arc castor bars, there is drainage gap, on every arc castor bar, offer a plurality of drain holes 2.For making structure design more rationally firm and symmetrical attractive in appearance, in the present embodiment, two groups of arc castor bars are symmetrical along the center line on this square cubic rain perforaled strainer length direction, and preferably the bending direction of two groups of arc castor bars is contrary simultaneously.
Shown in draining bridge 3(Fig. 3 and Fig. 4), be crossed on drainage gap, draining bridge 3 and drainage gap are corresponding one by one, on the two side of draining bridge, offer respectively a plurality of draining breach 5, the bottom of draining breach is concordant with the surface of arc castor bar, and current flow into drainage through draining breach 5 by drainage gap.When discharge, to cross bigger material too much, even if cause the drain hole 2 on arc castor bar 1 to stop up, current also can flow into drainage by drainage gap via 3 draining breach 5 on draining bridge.
By the difference in height that exists between draining bridge and arc castor bar and the unification of arc castor bar, arrange, so current can form eddy-currents in flow process, eddy-currents can be accelerated the flow velocity of water simultaneously.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 drainage through drain hole 2, drainage gap in this process as the grains of sand etc.
Because this square cubic rain perforaled strainer is less the closer to central area drain hole 2 and draining breach 5, drainage gap 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 drain module center, form vault, highly decline afterwards, by the poor formation eddy-currents of height of water level at vault and drain module 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 4 is established at the center of turbine rain perforaled strainer, and the inner end of all arc castor bars 1 is all connected with the circumference of disk 4.It is poor that the arranging of disk 4 can further increase the height of water level at the above-mentioned vault of mentioning and drain module center.Arc castor bar, from being tapered outside to inside, arranges the bearing strength that disk 4 also contributes to increase drain module central region simultaneously.On disk 4, also offer a plurality of drain holes 2 for draining.
When this square cubic rain perforaled strainer adopts at least two drain module, the bending direction of the arc castor bar of adjacent drainage channel module is contrary.Reality also can adopt the design that bending direction is identical, but obviously adopts contrary design, and the layout symmetry more attractive in appearance of arc castor bar in two drain module is convenient to make current to shunt simultaneously.When adopting two drain module, the bending direction of arc castor bar is oppositely arranged.
Embodiment bis-:
Embodiment bis-is basic identical with embodiment mono-structure, and the main distinction is when adopting two drain module, the opposing setting of bending direction of arc castor bar.During opposing setting, the arc castor bar junction of two drain module forms a plurality of concave inward structures (shown in figure bis-), the outer male structure (shown in figure mono-) that is oppositely arranged formation in comparative example one, outer male structure is compared concave inward structure and is more conducive to current shunting, so being oppositely arranged in preferential embodiment mono-.
In conjunction with the generally size of inlet for stom water and required displacement, generally adopt two drain module can meet drainage requirement, so embodiment mono-and embodiment bis-all to take two drain module be example.Radical, the width of arc castor bar 1, the number of drain hole 2 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 each drain module arc castor bar is generally limited to 2-50 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 embodiment, the drain hole on arc castor bar 2 is circular, and draining breach on draining bridge is irregular polygon 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 square cubic 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, square cubic rain perforaled strainer is one-body molded by mould, also can make respectively arc castor bar 1, 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 is by the spatial intersecting stereochemical structure between draining bridge and arc castor bar, adopt the combination of drain hole, draining breach and drainage gap that the blockage problem that guarantees displacement and solved double-edged fine-toothed comb is set, and by different foreign material in the effective separated flow of eddy-currents.And the present invention do 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.
