Embodiment one:
Please cooperate and consult square cubic rain grid made structural representation shown in Figure 1, square cubic rain grid made of the present utility model is made 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 grid bars 1, all arc grid bars stretch out from the drain module center, and the inner, the outer end of all arc grid bars are fixedly linked respectively, all arc grid bars are divided into two groups, two groups distribute about the drain module Central Symmetry, the bending direction of arc grate bar is consistent on the same group, and the bending direction of two groups of arc grid bars is identical or opposite; Have drainage gap between adjacent two arc grid bars, offer a plurality of drain holes 2 on the every arc grid bar.For making structure design more rationally firm and symmetrical attractive in appearance, two groups of arc grid bars are symmetrical along the center line on this square three-dimensional rain grid made length direction in the present embodiment, and the bending direction of preferred two groups of arc grid bars is opposite simultaneously.
Draining bridge 3(Fig. 3 and shown in Figure 4), be crossed on the drainage gap, draining bridge 3 and drainage gap 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 surperficial concordant with the arc grid bar, and current flow into drainage through draining breach 5 by drainage gap.To cross bigger material too much when discharge, even cause the drain hole 2 on the arc grid bar 1 to stop up, current also can flow into drainage by drainage gap via 3 draining breach 5 on the draining bridge.
Arrange by the difference in height that exists between draining bridge and the arc grid bar and the unification of arc grid bar simultaneously, so current can form eddy-currents in flow process, eddy-currents can be accelerated the flow velocity of water.According to hydraulic principle, the foreign material in the current are because centrifugal force and Action of Gravity Field, in the current floating thing of lighter weight such as leaf etc. can be pooled to the eddy-currents periphery with current not stop and rotation avoid its deposition to stop up to grate until current are emptied completely.And the heavier impurity of quality such as the grains of sand etc. can be assembled to the eddy-currents center and flow into drainage through drain hole 2, drainage gap in this process.
Because this square three-dimensional rain grid made is less the closer to central area drain hole 2 and draining breach 5, drainage gap is thinner, so the draining sectional area is also less.When discharge is excessive, can cause the catchment area at grate middle part to increase, water level rise can't form eddy-currents until form a whole water surface.Institute thinks that the generation eddy-currents is to guarantee the draining flow velocity, draining bridge 3 is designed to domes (Fig. 2 and shown in Figure 3), it is from increasing highly gradually outside to inside, form vault when closing on the drain module center, highly descend afterwards, by the poor formation eddy-currents of the height of water level at vault and drain module center, thereby guarantee the draining flow velocity.
The bridge floor of draining bridge 3 is provided with row's projection 31.When current reduced, the flow velocity of eddy-currents reduced, and floating thing deposits gradually, and projection 31 can be with 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 grid made, and the inner end of all arc grid bars 1 all is connected with the circumference of disk 4.Disk 4 that the height of water level that can further increase the above-mentioned vault of mentioning and drain module center is set is poor.The arc grid bar arranges the bearing strength that disk 4 also helps to increase the drain module central region from being tapered outside to inside simultaneously.Also offer a plurality of drain holes 2 on the disk 4 and be used for draining.
When this square three-dimensional rain grid made adopted at least two drain module, the bending direction of the arc grid bar of adjacent drainage channel module was opposite.Actual also can adopt the identical design of bending direction, but obviously adopt opposite design, the layout symmetry more attractive in appearance of arc grid bar is convenient to make the current shunting simultaneously on two drain module.When adopting two drain module, the bending direction of arc grid bar is oppositely arranged.
Embodiment two:
Embodiment two is basic identical with embodiment one structure, and the main distinction is when adopting two drain module, the opposing setting of the bending direction of arc grid bar.The arc grid bar junction of two drain module forms a plurality of concave inward structures (shown in Figure 2) during opposing the setting, the outer male structure (shown in Figure 1) that is oppositely arranged formation among the comparative example one, outer male structure is compared concave inward structure and more is conducive to the current shunting, so being oppositely arranged among the preferential embodiment one.
In conjunction with the generally size of inlet for stom water and required displacement, generally adopt two drain module can satisfy drainage requirement, so embodiment one and embodiment two are all take two drain module as example.The radical of arc grid bar 1, width, 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 grate bar that is applied to the rain grid made of biotope can arrange less and wide, and use with road on the grate bar of rain grid made can arrange many and thin.The radical of each drain module arc grid bar generally is limited to the 2-50 root, and drain hole and draining breach are done corresponding adjustment according to the number of grate bar.Drain hole is square hole, circular hole or polygon hole, and for example the drain hole on the arc grid bar 2 is circular among the embodiment, and the draining breach on the 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 guarantees bearing strength, to guarantee drain discharge.
The concrete economic budget of material basis of square cubic rain grid made and applied environment are selected has high strength and corrosion resistant plastics, metal or fibrous concrete etc.According to preferred embodiment, but also nonessential, the square cubic rain grid made is one-body molded by mould, also can make respectively arc grid 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 utility model is by the spatial intersecting stereochemical structure between draining bridge and the arc grid bar, adopt the combination of drain hole, draining breach and drainage gap that the blockage problem that guarantees displacement and solved grate is set, and by different foreign material in the eddy-currents effective separation current.And the utility model do not limit and is applied to road drainage system, all need to filter foreign material and draining equipment all can use this device.So the utility model has effectively overcome various shortcoming of the prior art and the tool high industrial utilization.
Above-described embodiment is illustrative principle of the present utility model and effect thereof only, but not is used for restriction the utility model.Any person skilled in the art scholar all can be under spirit of the present utility model and category, and above-described embodiment is modified or changed.Therefore, have in the technical field under such as and know that usually the knowledgeable modifies or changes not breaking away from all equivalences of finishing under spirit that the utility model discloses and the technological thought, must be contained by claim of the present utility model.
