Abstract
The invention discloses a sewer well lid and especially relates to a sewer well lid which automatically floats upward under a high flow condition, automatically resets under a small flow condition and is not plugged. The sewer well lid comprises an upper cover plate, a guide rod and a lower well base and is characterized in that a groove is arranged inside the lower well base; a guiding hole is formed in the groove; a plurality of flow-guiding slots are arranged on the upper cover plate; airtight air chambers are arranged between the flow-guiding slots; the average density of the upper cover plate and the guide rod is less than 0.9*103kg/m<3>; the guide rod passes through the guiding hole from the underside of the lower well base and is connected with the upper cover plate; at a use moment, the lower well base is poured in concrete floor and small flow water directly flows down from the flow-guiding slots of the upper cover plate and flows into a draining well along a wellhead; when the flow-guiding slots of the upper cover plate cannot meet the flow speed of high flow water, the upper cover plate floats in the lower well base, the upper cover plate is limited by the lowest end of the guide rod and water flows into the wellhead from a position between the upper cover plate and the lower well base; after the water flow is reduced, the upper cover plate descends and the upper cover plate enters into the groove of the lower well base under a guiding effect of the guide rod; and the practicability is strong.
Description
Technical field
The present invention relates to a kind of well cover for sewer, automatically float when particularly relating to a kind of large discharge and low discharge time automatically reset nonclogging well cover for sewer.
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 a kind of device rainwater being imported catch-basin, has simultaneously and prevents foreign material from entering sewer and prevent pedestrian and vehicle to fall into the effect of catch-basin.
Well cover for sewer is made up 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 well cover for sewer water inlet to block, especially during heavy rain, often block at the catch-basin of low-lying land.In the process that the guiding gutter forming well cover for sewer blocks, foreign material constantly pile up, and reduces streamflow gradually, finally cause total blockage.When rainwater collect speed exceed the drainability of urban pipe network time, the water in low-lying land catch-basin even can outwards overflow, when water level falls after rise, well lid is constantly covered by foreign material, causes impeded drainage, block even completely.If moved by well lid, workload when moving and cover back well lid is large and dangerous, in ponding, leave potential safety hazard.
Such as, often because well cover for sewer blocks cause ponding under overpass bridge, time serious, personal safety accident can be produced.
Through patent searching document, a kind of drainage manhole cover is just provided in patent document CN 201080650Y, concrete structure as shown in Figure 3, comprises well lid main body 1, it has water inlet, 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 opening of well lid main body 1, opening part has a disk 2, is connected with the floating block 4 be arranged in tank 3 below disk 2.Described tank 3 is connected in 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, and link 5 is fixed with pin 6.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 entering 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 exceedes urban pipe network is collected when rainwater, water in low-lying land catch-basin even can outwards overflow time, floating block 4 rises to peak, when water level falls after rise, floating block 4 has blocked the water inlet in well lid main body 1, and this technical scheme can not produce its design effect.
There is the defects such as displacement is little, complex structure, moving component are many, poor structural reliability, installation inconvenience in the drainage manhole cover of patent document CN 201080650Y.
Summary of the invention
The technical problem that the present invention solves is: the problem that the guiding gutter solving the well lid of the catch-basin of low-lying land during heavy rain blocks, and especially automatically floats during a kind of large discharge and low discharge is automatically reset nonclogging well cover for sewer.
The technical scheme of technical solution problem of the present invention is:
The invention discloses a kind of well cover for sewer, comprise upper cover plate, guide rod, seat of going into the well composition, it is characterized in that:
The inner side of described seat of going into the well is fluted;
Described seat of going into the well also comprises pilot hole, and pilot hole is in the groove of going into the well seat;
The centre of the groove of described seat of going into the well also comprises well head;
The outer of described upper cover plate is less than the groove of seat of going into the well, and when upper cover plate is put into and to be gone into the well, the upper surface of upper cover plate is equal with the upper surface of seat of going into the well;
Described upper cover plate there are many guiding gutters;
Sealed gas chamber is had between guiding gutter on described upper cover plate;
Described upper cover plate and the averag density of guide rod are less than 0.9 × 10
3kg/m
3;
Described guide rod is connected from the pilot hole that passes beneath of seat of going into the well with upper cover plate;
Described guide rod diameter bottom below seat of going into the well is greater than pilot hole;
During use, this drainage manhole cover is arranged on ground, seat of going into the well is cast in concrete surface, rill water gaging directly stays from the guiding gutter of upper cover plate, and water flows into lower well, when the guiding gutter of upper cover plate can not meet the flow velocity of large discharge water along well head, upper cover plate floats in seat of going into the well, the upper cover plate of restriction bottom of guide rod, water is from upper cover plate and go into the well between seat and flow into well head, after discharge reduces, upper cover plate declines, and upper cover plate enters in the groove of well seat under the guide effect of guide rod.
Principle of the present invention is:
The averag density of upper cover plate and guide rod is less than the density of water, if the water of large discharge covers upper cover plate, upper cover plate and guide rod can float in water.
Key technology of the present invention is: the averag density of upper cover plate and guide rod is less than 0.9 × 10
3kg/m
3.
Make Technical comparing with current patent certificate, the Advantageous Effects that the present invention obtains is: structure is simple, and well lid bearing capacity is large, and in water, foreign material can not block well lid, can not waft when well lid floats, and protection pedestrains safety, practicality is large.
