Abstract

A vortex suspended screw rain shutter grate relating to city road engineering rain drainage system field is provided. Drain holes are arranged in the rectangle shutter grate, wherein, a vortex flow center drain hole is arranged in an intersection point of two center diagonal lines of the shutter grate, spiral curve drain holes are arranged with the vortex flow center drain hole as a center of circle, gravity support sheets are positioned between adjacent curve drain holes. When used for draining rain, the utility model prevents contamination in the rain from entering a rain port, thereby ensuring clean and unobstructed when the rain enters a set of drainage pipe. The spiral curve drain holes are arranged according to certain order, which makes the drainage rain form a vortex flow, and contamination over the rain shutter grate floats in center portion of the vortex flow under the effect of the vortex flow and discharges into the drainage pipe. With two designs of clockwise screw plane shutter grate and counterclockwise screw plane shutter grate, the utility model can meet operating requirements when needing a set of adjacent double shutter grate rain ports or a set of multiple shutter grate rain ports.

Description

Whirlpool floating spiral downspout strainer

One, technical field

This practical property belongs to the urban road construction category, promptly with the supporting rain-water drainage facility of highway construction, it is arranged on the inlet for stom water of appropriate location, road both sides, be commonly called as " inlet for stom water grate ", its purpose be when rainy in time with the road surface on rainwater by the road design slope current to inlet for stom water, and the inlet for stom water grate be (hereinafter to be referred as " dirt ") grates such as branch that rainwater stream on the road surface is carried secretly, leaf, foreign material outside inlet for stom water, unimpeded to ensure the cleaning in the storm-water drainage pipeline.

Two, background technology

The inlet for stom water grate that uses in road construction at present is the flat grate of rectangle plate body that cast iron materials or cement concrete material are made, flat grate inner plane figure is little rectangle and forms the drain hole that various forms is arranged, this kind downspout strainer is playing the effect of dirt in the screen grate rainwater under normal rainfall situation, make that rainwater is unobstructed to be entered in the storm sewer.

The flat grate of this kind inlet for stom water is widely used in reason both sides, city.But when the period that rainfall is big, rainfall is concentrated, the flat grate of inlet for stom water is because when having more dirt in the rainwater in the low-lying area of road, and dirt can partly be blocked the inlet for stom water grate and influence draining.Person more very, dirt can be blocked inlet for stom water fully, causes rainwater in time not drain, and forms road surface large tracts of land ponding, and especially this phenomenon is more outstanding under overpass bridge.

At this moment, municipal workman at first smears with individual memory and looks for the inlet for stom water that is blocked before draining the water away, and then dirt is got rid of, and opens downspout strainer ponding is drained.

Rainwater gathering ground productive set is bigger when the road surface, and the low-lying place of road concentrates the inlet for stom water draining is set, and two grates or many grates are in order to the draining smoothness.Charge for remittance place in road surface is more typical under the overpass bridge.

Precipitation intensity often appears in road when rainy season bigger, when the rain-water drainage amount is concentrated, dirt on the road surface flows when being pooled to the inlet for stom water place with early-stage rainwater, and it is more and hinder the unobstructed discharge of rainwater dirt to occur, prolongs in time and causes the serious ponding in road surface to influence traffic.

Three, utility model content

The purpose of this utility model provides a kind of whirlpool floating spiral downspout strainer, solves existing grate gutter inlet blocked problem easily.

Technical scheme: this whirlpool floating spiral downspout strainer, the grate body profile is a rectangle, be distributed with drain hole in the grate body, it is characterized in that: there is eddy-currents central row water hole at the place at grate body center diagonal intersection point, with eddy-currents central row water hole is that the center of circle is evenly distributed with scroll curve drain hole, and the gravity support bar is arranged between the adjacent curve drain hole.

Above-mentioned scroll curve drain hole is clockwise curved arrangement or counterclockwise curved arrangement.

Its appearance and size of design of this whirlpool floating spiral downspout strainer is identical with present situation downspout strainer appearance and size, so that new and old replacing.Design is to be the helical curve figure (Archimedes spiral is seen accompanying drawing) in the center of circle with rectangle grate inner opposite angle line intersection point in its rectangle plane.Its cavity is the curve drain hole, this helical curve drain hole is arranged in order, to make rainwater form eddy-currents, and the whirlpool under the eddy-currents effect of dirt on the downspout strainer is floated on the eddy-currents core and leaves inlet for stom water, therefore rainwater can not be obstructed again and enter in the storm sewer smoothly.Except that cavity is the curve drain hole, also have real bar curved line in the figure, this is the gravity support bar of downspout strainer, and it satisfies the load-bearing supporting role of grate.

Because the present situation actual needs, the low-lying place of road is standing puts two grates or many gutter inlet gratings, so the design is provided with practical requirement with counter clockwise direction rotating screw curve in the direction of the clock.When adjacent inlet for stom water grate draining, the eddy current that every single gutter inlet grating forms is located two eddy current direction of rotation at its point of contact should be identical, and be designed to clockwise eddy current and counterclockwise eddy current, just in time identical in its place, point of contact direction of rotation.Under its many grates situation by that analogy.

Purposes of the present utility model may extend into similar settings such as the draining, oil extraction in other field.

Five, the specific embodiment

This whirlpool floating spiral downspout strainer, the grate body profile is a rectangle, be distributed with drain hole in the grate body, it is characterized in that: the diagonal intersection point place in grate body 1 has eddy-currents central row water hole 4, with eddy-currents central row water hole 4 is the curve drain hole 2 that the center of circle is evenly distributed with Archimedes spiral shape, and gravity support bar 3 is arranged between the adjacent curve drain hole.

The curve drain hole of above-mentioned Archimedes spiral shape is clockwise curved arrangement or counterclockwise curved arrangement.

Claims

1, a kind of whirlpool floating spiral downspout strainer, the grate body profile is a rectangle, be distributed with drain hole in the grate body, it is characterized in that: there is eddy-currents central row water hole at the place at grate body center diagonal intersection point, with eddy-currents central row water hole is that the center of circle is evenly distributed with scroll curve drain hole, is the gravity support bar between the adjacent curve drain hole.

2, whirlpool floating spiral downspout strainer according to claim 1 is characterized in that: above-mentioned curve drain hole is clockwise curved arrangement or counterclockwise curved arrangement.
