Abstract
The utility model provides a roof rainwater desilting device, relates to the field of urban water drainage, in particular to a roof rainwater desilting aspect, and aims to reduce risks of urban waterlogging caused by drainage pipeline blocking. According to the technical scheme, rainwater collected by a roof is injected to a vertical drainage pipe through a connecting pipe, the side face of the top of the vertical drainage pipe is provided with air exhausting hole, the top of the vertical drainage pipe is fixed with a dust proofing cap, the bottom of the vertical drainage pipe is connected to an elbow, the outer side of the bending part of the elbow is provided with sand exhausting holes, namely through holes of the wall of the elbow, and the bending part is located inside a desilting tank, the top of the desilting tank provided with an air exhausting pipe, and an opening of the outer side of the air exhausting pipe is located at the inlet of a sewer. The roof rainwater desilting device has the advantages that rainwater and sands maintain the inertia of linear motion and are exhausted through the sand exhausting holes; the sands are larger in specific gravity and are easy to settle in the bottom of the desilting tank; the roof is high, water flow speed is high, inertia is large, and desilting effect is significant; the roof rainwater desilting device is simple in structure and easy to implement.
Description
Technical field
The present invention relates to the desilting aspect in urban sewerage and drainage field, particularly rain water on roof.
Background technology
In current city, particularly northern, sand and dust are larger, airborne dust must be deposited in each corner in city, also comprise roof, the silt that the rainwater on roof is being mingled with will enter drainage pipe, and part silt can be deposited in drainage pipe, the risk that the line clogging of causing is arranged, the obstruction of drainage pipe just has the risk that causes the city waterlogging.
And generally smaller to the particle of the dust on roof by wind, if sewer has foreign material, tiny dust granule is dense, the intensity of foreign material and the compactness of fine dust, more easily cause the obstruction of storm sewer.
Summary of the invention
Stop up for reducing drainage pipe the risk that causes the city waterlogging, the present invention designs a kind of desilting device of roof rain water.
The present invention realizes that the technical scheme that goal of the invention adopts is: a kind of desilting device of roof rain water, it is characterized in that: the rainwater that roofing is collected is injected in the vertical drainage pipe by tube connector, there is steam vent the side at vertical drainage pipe top, a dust cap is fixed at the top of vertical drainage pipe, the bottom of vertical drainage pipeline connects a bend pipe, there is the sand discharge hole in the outside in the knee of bend pipe, the through hole that the sand discharge hole is the bend pipe tube wall, the inside of bent tube section in sand trap, a stack is arranged at the top of sand trap, the outer openings end of stack is positioned at the entrance of sewer.
Bend pipe adopts helix tube to replace, and there is the sand discharge hole in the outside of helix tube.The diameter in sand discharge hole is 1-3cm.
The invention has the beneficial effects as follows: object has the straight-line inertia of maintenance, and the rainwater of storm sewer is flowing through the pipe bent position of storm sewer, and rainwater and silt can keep inertia, from the sand discharge hole, go out; In sand trap, the speed of current is close to zero, the moisture of sand trap, and a part is back in bend pipe by the sand discharge hole, and a part is discharged to sewer by the stack of sand trap; The silt of rushing out from the sand discharge hole, due to than great, be easy to be deposited in the bottom of sand trap, and the part that is back to bend pipe or stack is less; Because roofing is higher, the flow velocity of water is large, and inertia is large, and the desilting effect is remarkable, and this apparatus structure is simple, easy to implement.
The accompanying drawing explanation
Fig. 1 is the drainage pipe schematic diagram of rain water on roof; Fig. 2 is improved bend pipe schematic diagram; Fig. 3 is the sand trap schematic diagram; Fig. 4 is the location diagram of storm sewer and sand trap.
Wherein, 1, roofing, 2, tube connector, 3, dust cap, 4, steam vent, 5, the vertical drainage pipe, 6, bend pipe, 7, the sand discharge hole, 8, helix tube, 9, sand trap, 10, stack.
The specific embodiment
The rainwater of roofing 1 is injected in vertical drainage pipe 5 by tube connector 2, air in vertical drainage pipe 5 can form a kind of retardation to draining, have influence on the speed of current, therefore, the open top of vertical drainage pipe 5, openend is vertically arranged several supports, form steam vent 4 between support, a dust cap 3 is fixed on the top of support, dust cap 3 reduces silt and foreign material enter vertical drainage pipeline 5, the bottom of vertical drainage pipeline 5 connects a bend pipe 6, there is sand discharge hole 7 in the outside in the knee of bend pipe 6, the through hole that sand discharge hole 7 is the bend pipe tube wall, bend pipe 7 can adopt helix tube 8 to replace, there is through hole in the outside of helix tube 8, it is sand discharge hole 7, the inside of bend pipe 6 parts in sand trap 9, a stack 10 is arranged at the top of sand trap 9, silt and rainwater enter sand trap 9 from sand discharge hole 7, the water level of sand trap 9 rises, squeeze the air in sand trap, the air squeezed is discharged from stack 10, water level rises to the top of stack 10 simultaneously, stack 10 also just becomes water pipe, therefore the openend of stack is positioned at the entrance of sewer.
