Abstract

The utility model provides a vertical rainwater perforated strainer. The vertical rainwater perforated strainer comprises a frame body, wherein multiple grates are arranged in the frame body in parallel and are of hollow structures, and multiple water drainage notches are formed in the two side walls of the grates. The water drainage capacity of the vertical rainwater perforated strainer can be used through the combination of the hollow grates and the water drainage notches in the side walls of the grates. Bulges on the top surfaces of the grates are used for stopping sundries in water currents. The blockage problem of the perforated strainer is solved while the water drainage capacity is ensured.

Description

Vertical rainwater double-edged fine-toothed comb

Technical field

The utility model relates to the draining field, relates in particular to a kind of vertical rainwater double-edged fine-toothed comb.

Background technology

Inlet for stom water is the important component part of urban sewerage and drainage system, operated by rotary motion in the block, square and kerbside ditch flow into the entrance of drainage as the surface flow rainwater, do not have road or caused road and low-lying regional ponding and block traffic or damage road to prevent rainwater.

Inlet for stom water is typically provided with the rainwater double-edged fine-toothed comb and filters foreign material, and common rainwater double-edged fine-toothed comb constitutes cell structure by many grizzly bars or square hole, in the time of draining the foreign material in the current is played the effect of holding back of filtering.The rainwater double-edged fine-toothed comb mainly contains two kinds of flat comb formula and upright comb formulas, the current of flat comb formula are more unobstructed, but the foreign material that the area that carries in the rainwater when running into heavy rain is bigger, as leaf, polybag, paper shell, food garbages etc. stop up at double-edged fine-toothed comb easily, reduce to receive outlet capacity, and foreign material are detained and too much double-edged fine-toothed comb can be shut, cause the ponding problem.

And the gutter that upright comb formula is installed need keep certain depth of water, and the cities and towns that have because increase on the road surface, reduce upright comb section because keeping in repair road year by year, and receipts water is slower during precipitation.In case the drainability deficiency may cause road table large tracts of land ponding, so the bleeder quantity of rainwater double-edged fine-toothed comb is the key of urban road surfaces Drainage Design.

The utility model content

The shortcoming of prior art in view of the above, the purpose of this utility model be to provide a kind of big bleeder quantity and to foreign material have than the strong filter ability vertical rainwater double-edged fine-toothed comb, be used for solving the problems of the prior art.

Reach other relevant purposes for achieving the above object, the utility model provides a kind of vertical rainwater double-edged fine-toothed comb, comprises framework, the interior parallel many castor bars that are provided with of framework, and described castor bar is hollow structure, and described castor bar two side all offers a plurality of draining breach.

Further, the end face of described castor bar is provided with a row projection.

Further, described framework is square.

By above technical scheme, the utlity model has following technique effect: the utility model arranges the assurance bleeder quantity by the combination of the draining breach of hollow castor bar and castor bar sidewall.And the projection by castor bar end face plays backstop action to the foreign material in the current, has solved the blockage problem of double-edged fine-toothed comb when guaranteeing displacement.

The specific embodiment

Below by particular specific embodiment embodiment of the present utility model is described, person skilled in the art scholar can understand other advantages of the present utility model and effect easily by the disclosed content of this manual.

See also Fig. 1 to Fig. 2.Notice, the appended graphic structure that illustrates of this manual, ratio, size etc., equal contents in order to cooperate manual to disclose only, understand and reading for person skilled in the art scholar, be not in order to limit the enforceable qualifications of the utility model, so technical essential meaning of tool not, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not influencing under the effect that the utility model can produce and the purpose that can reach, all should still drop on the technology contents that the utility model discloses and get in the scope that can contain.Simultaneously, quote in this manual as " on ", D score, " left side ", " right side ", " centre " reach the term of " " etc., also only for ease of understanding of narrating, but not in order to limit the enforceable scope of the utility model, the change of its relativeness or adjustment, under no essence change technology contents, when also being considered as the enforceable category of the utility model.

See also Fig. 1 to Fig. 2, Fig. 1 to Fig. 2 shows a kind of embodiment of the vertical rainwater double-edged fine-toothed comb of the utility model, comprises framework 1, and framework 1 is for adapting to the square of conventional inlet for stom water, and parallel in the framework 1 to be provided with many castor bar 2(shown in Figure 1).Castor bar 2 is hollow structure, and all to offer a plurality of draining breach 3(shown in Figure 2 in castor bar two side).Generally, current can flow into drainage via the seam of the comb between the castor bar.When discharge was excessive, making the most of the advantage in conjunction with arranging of hollow castor bar and draining breach increased bleeder quantity.

And the end face of castor bar is provided with a row projection 4, can play certain backstop action to the floating thing in the water, and therein on one or a few castor bar, all the other castor bars still guarantee normal draining with its backstop.

In conjunction with the generally size of inlet for stom water and required displacement, number, the size of the radical of castor bar 2, width and draining breach 3 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 rainwater double-edged fine-toothed comb of biotope can arrange less and wide, and use with road on the castor bar of rainwater double-edged fine-toothed comb can arrange many and thin, the draining breach is done corresponding adjustment according to the bar number of castor bar.The hole shape setting principle of draining breach is should be big as far as possible under the situation that guarantees bearing strength, and to guarantee drain discharge, in the present embodiment, the draining breach is irregular polygon hole shape.

The concrete economic budget of material basis of vertical rainwater double-edged fine-toothed comb and applied environment are selected for use has high strength and corrosion resistant plastics, metal or fibrous concrete etc.According to preferred embodiment, but and nonessential, vertical rainwater double-edged fine-toothed comb is one-body molded by mould, also can make framework 1, castor bar 2 respectively, integrally welded or other connected mode is spliced into one with it then, as bayonet socket, draw-in groove are set are used for clamping.

In sum, the vertical rainwater double-edged fine-toothed comb of the utility model arranges the assurance bleeder quantity by the combination of the draining breach of hollow castor bar and castor bar sidewall.And the projection by castor bar end face plays backstop action to the foreign material in the current, has solved the blockage problem of double-edged fine-toothed comb when guaranteeing displacement.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.
