Abstract
The utility model discloses a sewer well cover, in particular relates to a sewer well cover which automatically floats upwards when the flow is large, automatically returns when the flow is small and is not blocked. The sewer well cover comprises an upper cover plate, a guide rod and a lower well seat, and is characterized in that a guide hole is formed in a groove inside the lower well seat; a plurality of flow guide grooves are formed in the upper cover plate; a closed air chamber is formed between the flow guide grooves; the average density of the upper cover plate and the guide rod is smaller than 0.9*10<3> kg/m<3>; and the guide rod penetrates through the guide hole below the lower well seat and is connected with the upper cover plate. When the sewer well cover is used, the lower well seat is poured in a concrete ground, and small-flow water directly flows downwards from the flow guide grooves of the upper cover plate, and flows into a sewage well along a wellhead; when the flow guide grooves of the upper cover plate cannot meet the flow speed of large-flow water, the upper cover plate floats from the interior of the lower well seat, and is limited by the lowermost end of the guide rod, and the water flows into the wellhead from a space between the upper cover plate and the lower well seat; and after the flow of the water is reduced, the upper cover plate descends, and enters the groove of the lower well seat under the guide action of the guide rod. The sewer well cover is high in practicality.
Description
Technical field
The utility model relates to a kind of well cover for sewer, automatic automatically reset nonclogging well cover for sewer when floating and low discharge when relating in particular to a kind of large flow.
Background technology
Well cover for sewer is commonly called as leaf grating for down pipe, is the well lid of road both sides catch-basin.Well cover for sewer is rainwater to be imported a kind of device of catch-basin, has simultaneously to prevent that foreign material from entering the effect that sewer and prevention pedestrian and vehicle are fallen into catch-basin.
Well cover for sewer is comprised of go into the well seat and cover plate, and the guiding gutter in the middle of cover plate is the passage of rainwater trickling.When rainy, due to the transportation of waterpower, the article such as polybag, waste paper, waste wood sheet can block the guiding gutter in the middle of cover plate, cause the well cover for sewer water inlet to block, and especially during heavy rain, often block at the catch-basin of low-lying land.In the process that the guiding gutter that forms well cover for sewer blocks, foreign material are constantly to pile up, and reduce gradually streamflow, finally cause total blockage.When the collecting speed and surpass the drainability of urban pipe network of rainwater, the even outwards overflow of water in the low-lying land catch-basin when water level falls after rise, is constantly covered by foreign material on well lid, causes impeded drainage, even fully obstruction.If well lid is moved, move and the workload when covering back well lid large and dangerous, stay potential safety hazard in ponding.
For example often cause ponding because well cover for sewer blocks under overpass bridge, can produce the personal safety accident when serious.
Through the patent searching document, just provide a kind of drainage manhole cover in patent documentation CN 201080650Y, concrete structure comprises well lid main body 1 as shown in Figure 3, and water inlet is arranged on it, wherein, be provided with tank 3 below well lid main body 1, tank 3 is connected with well lid main body 1 by connector, at the center of well lid main body 1 opening, opening part has a disk 2, is connected with the floating block 4 that is arranged in tank 3 below disk 2.Described tank 3 is connected on well lid main body 1 by four cylinders, and the sidewall of tank 3 is provided with weep hole.Described disk 2 is connected with floating block 4 by link 5, is fixed with pin 6 on link 5.Because the total sectional area of the water conservancy diversion aperture on well lid main body 1 surface is little, when just there has been ponding on ground, if the water conservancy diversion aperture on well lid main body 1 surface blocks, cause the water shortage that enters tank 3, water flows out from the weep hole of tank 3, floating block 4 just can not float, and disk 2 can not upwards boost, and can not produce the effect of design.The drainability that speed surpasses urban pipe network of collecting when rainwater, even outwards during overflow, floating block 4 rises to peak to water in the low-lying land catch-basin, when water level falls after rise, floating block 4 has blocked the water inlet on well lid main body 1, and this technical scheme can not produce its design effect.
There are the defectives such as displacement is little, complex structure, moving component is many, structural reliability is poor, installation is inconvenient in the drainage manhole cover of patent documentation CN 201080650Y.
Summary of the invention
The technical problem that the utility model solves is: the problem that when solving heavy rain, the guiding gutter of the well lid of the catch-basin of low-lying land blocks, especially floating and low discharge are automatically reset nonclogging well cover for sewers automatically during a kind of large flow.
The technical scheme of the utility model technical solution problem is:
The utility model discloses a kind of well cover for sewer, comprise upper cover plate, guide rod, the seat of going into the well forms, it is characterized in that:
Described the inboard fluted of seat of going into the well;
The described seat of going into the well also comprises pilot hole, and pilot hole is in the groove of seat of going into the well;
The centre of the groove of the described seat of going into the well also comprises well head;
The outer of described upper cover plate is less than the groove of the seat of going into the well, and when upper cover plate was put into and gone into the well, the upper surface of upper cover plate and a upper surface of going into the well were equal;
Many guiding gutters are arranged on described upper cover plate;
Between guiding gutter on described upper cover plate, sealed gas chamber is arranged;
The averag density of described upper cover plate and guide rod is less than 0.9 * 10
3Kg/m
3
Described guide rod passes pilot hole and is connected with upper cover plate below the seat of going into the well;
Described guide rod below the seat of going into the well bottom diameter greater than pilot hole;
During use, this drainage manhole cover is arranged on ground, the seat of going into the well is cast in concrete surface, the rill water gaging directly stays from the guiding gutter of upper cover plate, and water flows into lower well along well head, when the guiding gutter of upper cover plate can not satisfy the flow velocity of large flow water, upper cover plate floats in the seat of going into the well, the upper cover plate of restriction bottom of guide rod, water are from upper cover plate and go into the well and flow into well head between seat, after discharge reduces, upper cover plate descends, and upper cover plate enters in the groove of well seat under the guide effect of guide rod.
Principle of the present utility model is:
The averag density of upper cover plate and guide rod is less than the density of water, if the water of large flow covers upper cover plate, upper cover plate and guide rod can float in water.
