Abstract
The utility model provides a kind of city anti-waterlogging drainage system, comprise drainage pipe, threeway, one way valve, water pump, gutter, three openings of described threeway are communicated with pump intake with described drainage pipe, one way valve respectively by pipeline, and the delivery port of described water pump is connected with gutter.The beneficial effects of the utility model are: when river water level is lower, urban sewerage and drainage is discharged by one way valve; When river water level is increased beyond drainage pipe, in drainage pipe, water can not outside discharge pipe, and now closed check valve prevents river course Nei Shui from pouring in down a chimney and enters drainage pipe; Ball float water level inductive switching, to water level abnormality, starts water pump in pump house, and in drainage pipe, water is extracted out discharged to river course via water pump, effectively can reduce the generation of urban waterlogging and accelerate Urban Waterlogging speed.
Description
Technical field
The invention belongs to municipal water supply and draining field, especially relates to the anti-waterlogging drainage system in a kind of city.
Background technology
Global warming, extreme weather is more and more frequent, and extreme rainfall has partially strong trend on the high side.In today of rapid urban, major part original pond, ditch, depression, greenery patches etc. all replace by the fluid-tight hardened ground such as building, road, cause earth's surface to absorb the ability of being detained rainwater significantly to be weakened, rainwater major part all will be drained by drainage system, cause a lot of city when meeting with heavy showers, drainage system can't bear the heavy load, water in drainage pipe can not be discharged to river course in time, and river water level rises and causes and pour in down a chimney thus cause waterlogging, urban traffic is paralysed, and also causes great threat to people life property safety.
Summary of the invention
The problem that the invention will solve prevents urban waterlogging.
For solving the problems of the technologies described above, the technical scheme that the invention adopts is: the anti-waterlogging drainage system in city, comprise drainage pipe, threeway, one way valve, water pump, gutter, three openings of described threeway are communicated with pump intake with described drainage pipe, one way valve respectively by pipeline, and the delivery port of described water pump is connected with gutter.
Preferably, described drainage pipe is municipal drainage pipeline, to be entered by municipal wastewater in river course or sea or reservoir by one way valve.
Preferably, also comprise water level sensor or ball float water level switch, described water level sensor or ball float water level switch-linear hybrid, above described drainage pipe, can control the unlatching of water pump.
Preferably, on described water level sensor or the ball float water level switch-linear hybrid pipeline outer wall above described drainage pipe or the river course above described drainage pipe or retaining pool wall.
Preferably, described one way valve is duckbill valve.
The advantage that the invention has and good effect are:
Owing to adopting technique scheme, when river water level is lower, urban sewerage and drainage is discharged by duckbill valve; When river water level is increased beyond drainage pipe, in drainage pipe, water can not outside discharge pipe, and now duckbill valve is closed and prevented from river course Nei Shui from pouring in down a chimney entering drainage pipe; Water level sensor or ball float water level inductive switching are to water level abnormality, start water pump in pump house, in drainage pipe, water is extracted out discharged to river course via water pump, effectively can reduce the generation of urban waterlogging and accelerate Urban Waterlogging speed, when water level in drainage pipe or in river course is automatically out of service lower than water pump when water level sensor or float switch controlling water level.
Accompanying drawing explanation
In order to be illustrated more clearly in the invention embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only the embodiment of the invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the schematic diagram of the invention.
In figure:
1, gutter 2, threeway 3, one way valve 4, water pump
5, gutter 6, water level sensor or ball float water level switch
Detailed description of the invention
Below in conjunction with the accompanying drawing in the invention embodiment, be clearly and completely described the technical scheme in the invention embodiment, obviously, described embodiment is only the invention part embodiment, instead of whole embodiments.Based on the embodiment in the invention, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the invention protection.
Set forth a lot of detail in the following description so that fully understand the invention, but the invention can also adopt other to be different from alternate manner described here to implement, those skilled in the art can do similar popularization under the condition without prejudice to the invention intension, and therefore the invention is not by the restriction of following public specific embodiment.
As shown in Figure 1; the invention comprises drainage pipe 1, threeway 2, one way valve 3, water pump 4, gutter 5; three openings of described threeway 2 are communicated with water pump 4 water inlet with described drainage pipe 1, one way valve 3 respectively by pipeline; the delivery port of described water pump 4 is connected with gutter 5; described drainage pipe 1 is municipal drainage pipeline, to be entered by municipal wastewater in river course or sea or reservoir by one way valve 3.
Also comprise water level sensor or ball float water level switch 6, described water level sensor or ball float water level switch 6 are arranged on the top of described drainage pipe 1, respond to the water level of river course (sea or reservoir) and municipal drainage pipeline simultaneously, the unlatching of water pump 4 can be controlled when river course (sea or reservoir) and municipal drainage pipeline water level contact with water level sensor or ball float water level switch simultaneously, water is discharged by water pump; When any point water level does not contact water level sensor or ball float water level switch, water pump 4 is out of service.
On the river course that described water level sensor or ball float water level switch 6 are arranged on the pipeline outer wall of the top of described drainage pipe 1 or the top of described drainage pipe 1 or retaining pool wall.
Described one way valve 3 is duckbill valve.Described water pump can be placed in special pump house, is convenient to management and maintenance.
Owing to adopting technique scheme, when river water level is lower, urban sewerage and drainage is discharged by duckbill valve; When river water level is increased beyond drainage pipe, in drainage pipe, water can not outside discharge pipe, and now duckbill valve is closed and prevented from river course Nei Shui from pouring in down a chimney entering drainage pipe; Ball float water level inductive switching, to water level abnormality, starts water pump in pump house, and in drainage pipe, water is extracted out discharged to river course or sea or reservoir via water pump or other are local, effectively can reduce the generation of urban waterlogging.When water level in drainage pipe or in river course is automatically out of service lower than water pump when water level sensor or float switch controlling water level.
Above an embodiment of the invention has been described in detail, but described content being only the preferred embodiment of the invention, the practical range for limiting the invention can not being considered to.All equalization changes done according to the invention application range with improve, within the patent covering scope that still all should belong to the invention.
