Description
Technical field
The utility model relates to a kind of round platform device realizing the orderly drainage waterlogging prevention in city.
Background technology
In urban sewerage and drainage system, the physical features significant difference of zones of different affects the drainability of respective regions drainage pipe and the drainage effect in heavy showers.Relevant theoretical according to hydrodynamics, under head pressure effect, the water flow in pipeline increases with the rising of head pressure.So when each discharge pipe line is same caliber, high elevation region is due to higher head pressure, and pipeline has more powerful drainability, in short-term during heavy showers, surface rain is drained fast by discharge pipe line after importing collecting well; And hypsography low-lying area head pressure is low, tubes rows outlet capacity is relatively weak, and rainwater is difficult to drain in time and be detained in a large number.Current China urban drainage pipe network layout mostly is " linker " pattern (namely in some areas, city, the drainage pipeline networks of high and low topography areas shares same main line), when rainfall exceedes the load of drainage pipeline networks, rainwater is excessive from hypsography low-lying region collecting well, causes effectiveness factors.On the other hand, surface rain from high elevation field flow orientation hypsography low-lying region, increases the weight of the burden of low lying areas drainage pipeline networks under gravity, increases the occurrence probability of low lying areas effectiveness factors.
In sum, when city meets with heavy showers in short-term, the draining burden that hypsography low-lying region pipe network faces is higher than high elevation region, and drainability is weaker than high elevation region.This hull-borne of network of underground is totally unfavorable to alleviation urban waterlogging.Unchanged descending under pipe network condition, suitably weakening the drainability in high elevation region, allowing hypsography low-lying region preferentially discharge is the effective way changing this hull-borne.
Summary of the invention
When to meet with heavy showers in city in order to solve existing water drainage mode effectively can not limit the storm-water drainage speed in high elevation region, very easily cause the deficiency of low-lying region effectiveness factors, the utility model provide a kind of effectively can limit high elevation region storm-water drainage speed, accomplish that hypsography low-lying area is preferentially discharged, realize the round platform device of the orderly drainage waterlogging prevention in city.
The technical solution adopted in the utility model is:
Realize the round platform device of the orderly drainage waterlogging prevention in city, it is characterized in that: the network of underground comprising city and the collecting well be communicated with described network of underground, described network of underground connects main line, the delivery port of described collecting well is provided with current screw generating means, described current screw generating means is the shell with oblique truncated cone-shaped, and there is the inner chamber of hollow, the smaller diameter end of described shell is facing to the delivery port of collecting well, major diameter end face deviates from the delivery port of collecting well and is arranged on collecting well inside, described current screw generating means has tangential water inlet and the Axial-running Out mouth of a river, the described Axial-running Out mouth of a river is arranged on minor diameter end face, the described Axial-running Out mouth of a river is communicated with the gutter of the water outlet of described collecting well, described tangential water inlet be arranged on angle between bus and vertical direction less and on the side of major diameter end, water is imported inner chamber with the tangential direction of the side surface circumference of described shell by described tangential water inlet.
Further, the current screw generating means being arranged on the delivery port of the collecting well of high elevation has the eddy current genetic coefficient higher than the current screw generating means of the delivery port of the collecting well being arranged on low-lying.
The course of work of the present utility model is as follows:
1, when rainfall intensity is less, the water yield entering collecting well is also corresponding less, not yet to drainage system build-up of pressure, without the need to regulating the rainwater flow of discharge pipe line.Now, the head in collecting well is lower, and water flow stationary is by current screw generating means.
2, along with the increase of rainfall intensity and rain time, when in collecting well, water level rises to certain altitude gradually, due to the effect of the inertia of current and the planform of current screw generating means, current form the screw around apparatus structure axis in device inside, now water velocity is not enough to maintain stable screw form, this screw is crumbled and fall after a period of time has passed, is formed afterwards again, goes round and begins again.The appearance of this forms of motion means that the water velocity component along outlet pipe axis reduces, the corresponding reduction of flow in collecting well outlet conduit, now current screw generating means is not yet full of by water, and its inside still has a certain amount of air, further reduces the actual area of passage of current.
3, when water level in collecting well raises further, current screw generating means is flooded completely, and current form stable screw in device inside and collecting well outlet conduit, and the movement velocity along outlet conduit axis reduces further.Meanwhile, a small amount of air is limited in the centre of screw current, and this will produce back pressure to current, and reduces the area of passage of current in drainage pipe.Under the acting in conjunction of above factor, the flow of discharging collecting well is effectively contained.
4, after rainfall terminates, along with the decline of water level in collecting well, in drainage pipe, the helical flow form of current fades away, and drainage system recovers normal condition.
When the short time concentrates rainfall, the temporary transient water storage of collecting well in high elevation region and this region is unlikely to cause local waterlogging.Urban waterlogging often shows indivedual low-lying regions repeatedly waterlogging, instead of the waterlogging of Zone Full.The utility model finds, it is unordered that the origin cause of formation of urban waterlogging comprises in draining order, and cause low-lying area sewerage smooth thus, and the storage capacity of the collecting well in high elevation region is not fully used, the whole efficiency of urban sewerage and drainage facility declines.The utility model creatively implements the effective management of urban sewerage and drainage facility in draining order, improves the service efficiency of urban sewerage and drainage facility.
The beneficial effects of the utility model are embodied in:
1, the utility model does not change the present situation (layout of drainage pipeline networks, design), at high elevation set of regions well outlet conduit, current screw generating means is installed, when collecting well middle water level reach a certain height, this device starts, work, tangential inlet structure makes current flow into drainage pipe in a spiral form, slow down flow rate of water flow, the drainability in restriction and reduction high elevation region, thus improve the drainability in hypsography low-lying region, the flow of the different physical features drainage pipe of automatic synchronization, realize the orderly draining of system, eliminate or alleviate the effectiveness factors that low lying areas are caused by heavy showers in short-term.Do not need the energy, invest low, instant effect.
2, the utility model can design the structure and performance parameters of each current screw generating means according to the distribution situation of city area underdrainage pipe network system, topography and geomorphology, really realize the orderly draining of this region underdrainage pipe network system, reach the target preventing low lying areas, city waterlogging.
3, because the true form in drainage pipe cross section and area remain unchanged, line clogging risk is decreased.
