Abstract
The utility model discloses a dustproof rain cover, and relates to municipal drainage, and in particular relates to the dustproof rain cover which can prevent dust from entering into the drainage pipeline in ordinary time. As common rain cover is not provided with a shield, dust and fine impurities enter into the rain cover, so that the rain cover is blocked before the rainy reason. In order to prevent dust and fine impurities from falling into the rain cover, a dustproof rain cover is designed. The technical scheme is as follows: a covering plate covers a drainage area of the rain cover, a part of a headrace channel and a drainage hole are arranged below the covering plate; the drainage area is arc-shaped. Both sides of the drainage area sink to form a sand sinking area; three through holes are formed in the top of the arc-shape for fixing the covering plate; a layer board is arranged below the rain cover and is provided with a drainage nest and a balloon lifting pit, wherein a seepage hole is formed in the middle of the balloon lifting pit. The dustproof rain cover provided by the utility model has the beneficial effects that the covering plate covers the drainage hole without rain water, so that dust and impurities cannot enter into the drainage pipeline. Sanitation workers can clean and remove almost dust and impurities. A part of the headrace channel is not covered, so that the headrace channel is smooth.
Description
Technical field
The present invention relates to urban sewerage and drainage, particularly a kind of anti-dust-shower lid of avoiding dust at ordinary times to enter drainage pipe.
Background technology
In China, the time that the time ratio that does not rain rains is much more, common rainwater lid, owing to do not block, dust and foreign material in small, broken bits can enter the rainwater lid down, during the environmental sanitation cleaning, also have part fragment and silt and fall into the rainwater lid down, before causing arriving rainy season, the rainwater lid has stopped up down, causes the city waterlogging easily.
Enter rainwater lid foreign material down, under rainwash, part has moved a segment distance, clear up also very inconvenient, nor thorough.
Summary of the invention
For avoiding foreign material and dust falling at ordinary times under the rainwater lid, the present invention designs a kind of anti-dust-shower lid.
The present invention realizes that the technical scheme that goal of the invention adopts is: a kind of anti-dust-shower lid, constitute by rain lid, balloon, supporting plate, it is characterized in that: rain is stamped load-bearing district and catchment, covers covering plate above the catchment, and covering plate hides a part and the drain hole of the disposal ditches of catchment; The catchment presents arc, and the both sides depression is desilting zone, and middle outstanding, three through holes are arranged at the arc top, are used for fixing covering plate, and correspondingly covering plate has three projections; Drain hole is positioned at the top of arcuate segments, and two row's drain holes are arranged, and the disposal ditches is positioned at the outside of drain hole, and the disposal ditches is connected with drain hole; It is a supporting plate that the rain lid descends, and primary structure has draining nest and balloon to lift the hole, and there is an infiltration hole centre that balloon is lifted the hole, and the diameter in infiltration hole is identical with drain hole; Balloon is connected with covering plate by connecting rod.
Rainwater lid thickness 10cm, the desilting zone lowest part thickness of catchment is 2cm, surface, the distance from top load-bearing district of the arc of catchment is 2cm.
Load-bearing sector width 10cm, catchment width 10cm, the long 2cm in disposal ditches, initial position is 0cm apart from surface distance, the junction that the disposal ditches is connected with drain hole is apart from curved surfaces 1cm, drain hole diameter 5-10mm, preferred 5mm.
Supporting plate is made up of metal sheet roof covering or rigid plastics.
Balloon is lifted hole radius 5cm, dark 5cm, is a hemispherical.
Connecting rod is a semi-rigid plastic, and connected mode is a removably, such as two parts that link together, outstanding, the parts depression of parts, after being inserted in, have over against through hole, pass through hole by lead-in wire and fix.
The filler of balloon is a foamed material.The airballoon cover thickness 0.3-0.5mm of balloon adopts rubber.
Covering plate adopts rubber or semi-rigid plastic.
Beneficial effect of the present invention: do not have rainwater to arrive, covering plate covers drain hole, and dust and foreign material can't enter drainage pipe; The catchment presents arcuate structure, drain hole and disposal ditches are positioned at the top of arcuate segments, dust and foreign material can be collected at the desilting zone of both sides, catchment at ordinary times, and the sanitationman can shift out most dust and foreign material by cleaning, can guarantee the unobstructed of disposal ditches and drain hole; The disposal ditches covered plate of a part covers, a part is not capped, the link position of disposal ditches and drain hole is in the high point of vertical direction, tiny current, such as spotting or sprinkling truck watering, because silt is than great, the fluctuation of water or come washing away of water, help silt and assemble, and guarantee the unobstructed of disposal ditches to desilting zone; Covering plate is pasting the catchment basically, and the disposal ditches part is not capped, and just guarantees that also disposal ditches and covering plate have the space, can realize a small amount of draining.

The specific embodiment
A kind of anti-dust-shower lid, constitute by rain lid 1 and supporting plate 11, rain is stamped load-bearing district and catchment 2, cover covering plate 3 above the catchment, covering plate 3 hides a part and the drain hole 6 of the disposal ditches 5 of catchment, catchment 2 presents arc, the both sides depression is desilting zone 4, and is middle outstanding, rainwater covers 1 preferred thickness 10cm, the lowest part thickness 2cm of both sides, catchment depressions, the distance from top load-bearing district surface 2cm of arc, three through holes 7 are arranged at the arc top, be used for fixing covering plate 3, correspondingly covering plate 3 has three projections.
The disposal ditches is positioned at the top area of catchment 2 arcs, catchment width 10cm, the long 2cm in disposal ditches, disposal ditches 5 is connected with drain hole 6, and the disposal ditches, junction is apart from curved surfaces 1cm, and the water of the disposal ditches direction that flows presents slightly and is inclined upwardly like this, help reducing silt and enter drainage pipe, drain hole diameter 5-10mm, preferred 5mm avoids big foreign material to enter drainage pipe.
It is a supporting plate that rain lid 1 descends, and is made up of metal sheet roof covering or rigid plastics, and primary structure has draining nest 12 and balloon to lift hole 13, balloon is lifted hole radius 5cm, dark 5cm, be a hemispherical, there is an infiltration hole 14 centre that balloon is lifted hole 13, and the diameter in infiltration hole 14 is identical with drain hole 6.Balloon 16 is connected with covering plate 3 by connecting rod 15, and connecting rod 15 is a semi-rigid plastic, and the filler of balloon 16 is a foamed material, and airballoon cover thickness 0.3-0.5mm adopts rubber, and covering plate 3 adopts rubber or semi-rigid plastic.
Operation principles: at ordinary times, covering plate 3 is with drain hole 6 and water-guiding hole 5 most of coverings, because the catchment is an arcuate structure, the dust foreign material tend to be collected at desilting zone 4, when the sanitationman cleans most foreign material are cleaned away, do not have foreign material to enter drainage pipe; When raining, rainwater is flushed to desilting zone with the silt of catchment earlier, along with coming increasing of water, rainwater 5 enters drain hole 6 from the disposal ditches, flow into balloon then and lift hole 13, when rainfall is big, balloon is lifted the hole will fill rainwater, balloon is held up, by connecting rod, covering plate 3 is held up, the increasing drain hole contacts with rainwater, accelerate draining, a large amount of rainwater enters drainage pipe by draining nest 12.After rain stops, balloon is lifted hole 13 residue rainwater from infiltration hole 14 drainings, because the diameter in infiltration hole is the same big or small with the diameter of drain hole, does not have foreign material and remains in balloon and lift the hole, the balloon action of gravity moves down, and drives covering plate 3 by connecting rod drain hole 6 and disposal ditches 5 are hidden.
