Description
Technical field
The utility model is related to a kind of culvert pipe priming device, belongs to field irrigation technical field.
Background technology
The layout pattern of irrigation pumping station water intake engineering is divided into two kinds of water channeling type and shore type, and irrigation pumping station diversion is taken from mostly
River course, raceway groove, when the raceway groove bank gradient is steeper, pumping plant layout pattern typically uses shore type；When Channel slope relatively delays mostly
When, and required to meet flood control, irrigation pumping station preferably uses water channeling type to arrange.Current water channeling type pumping plant water intaking is general to be drawn using open channel
Water (as shown in Figure 1), open channel diversion is made up of open diversion canal and forebay, although it has advantages of simple structure and simple, this shape
Formula easily causes the silting of open diversion canal and forebay, is especially become apparent in the larger irrigation areas of sediment charge.Culvert pipe diversion
There is easy construction, farmland saving and duct cleaning, but because the Yellow River is fully-loaded stream, Sediment Siltation turns into relation
To the key issue of pumping plant safe operation, outstanding husky alluvial is the main cause of irrigation areas irrigation pumping station water intake engineering alluvial.It is small
After unrestrained bottom reservoir builds up operation, cause the Yellow River downstream channel continuous erosion, irrigation areas big flow diversion probability reduces, middle rill
Amount diversion probability increases, and diversion takes sand and enters canal chance and increases, therefore culvert pipe diversion also has problems for irrigation areas.
The content of the invention
Technical problem to be solved in the utility model is directed to the defect of prior art presence, there is provided a kind of culvert pipe diversion
Culvert pipe diversion alluvial problem in yellow irrigation is drawn in formula pumping plant, solution.
To solve this technical problem, the utility model provides a kind of culvert pipe water channeling type pumping plant, including is provided with centrifugal pump
Pump house, diversion culvert pipe and water intake with vavuum pump, diversion culvert pipe connection water intake and centrifugal pump；The diversion culvert pipe far water source
End is inclined by 2% gradient to river course, and then 45 ° of side slope stretches to river bed along the river, and diversion culvert pipe bottom sets water intake, outside water intake
If blocking dirty cage, water intaking culvert pipe 90 ° of water intakings orthogonal with river course, water is confluxed by water intake and enter pump house, centrifugal pump in diversion culvert pipe
Drive water circulation.
The diversion culvert pipe is provided with many places sediment ejection opening, and recoil mouth is provided with diversion culvert pipe bending intersection.
The water intake is provided with least one water inlet.
The vacuum-pumping tube caliber of the vavuum pump is Φ 50mm.
The diversion culvert pipe is connected and composed by many single culvert pipe.
The diversion culvert pipe sets anchor block every 10m, and the anchor block uses grade to be made for the plain concrete cast of C15.
The diversion culvert pipe is provided with bottom valve with water intake junction, and the bottom valve is closed by self gravitation, in centrifugation
Opened during pump work.
It is described to block dirty cage and be made up of the arrangement of bar of the spacing 2cm of Φ 6, block dirty cage and be placed in river bed.
The intake upstream and downstream sets 10m bank protections.
Beneficial effect：The utility model designs and arranges corresponding water intake engineering according to the characteristics of field irrigation, reasonably
Facility, it is ensured that water intaking safety, not only reduces construction investment, and reduces operating cost, and the irrigation pumping station form is worth in class
As area promote, huge economic benefit will be produced.
Brief description of the drawings
Fig. 1 is the structural representation of prior art open channel diversion；
Fig. 2 is structural representation of the present utility model.
In figure：Dirty cage, 5 sediment ejection openings, 6 recoil mouths, 7 bottom valves, 8 anchor blocks are blocked in 1 pump house, 2 diversion culvert pipe, 3 water intakes, 4.
Specific embodiment
Below in conjunction with the accompanying drawings and embodiment is specifically described to the utility model.
Fig. 2 show structural representation of the present utility model.
The utility model includes being provided with pump house 1, diversion culvert pipe 2 and the water intake 3 of centrifugal pump 9 and vavuum pump 10, and diversion is contained
Pipe 2 connects water intake 3 and centrifugal pump 9, and its length is determined by water-fetching head with the distance of pump house.
The diversion culvert pipe 2 is connected and composed by many single culvert pipe, and the caliber of diversion culvert pipe 2 determines according to flow system flow,
Culvert pipe length is determined by conditions such as landform, landforms.
The diversion culvert pipe 2 sets anchor block 8 every 10m, and the anchor block 8 uses grade to be made for the plain concrete cast of C15.
The water intake 3 is provided with least one water inlet.
The diversion culvert pipe 2 is provided with bottom valve 7 with the junction of water intake 3, and the bottom valve 7 is closed by self gravitation,
Opened when centrifugal pump 9 works.
The 90 ° of water intakings orthogonal with river course of the intake pipe of the water intake 3, upstream and downstream sets 10m bank protections at the water intaking；Water passes through
Water intake 3 to conflux and enter pump house 1 in diversion culvert pipe 2, and centrifugal pump 9 drives water circulation.
Because the startup of centrifugal pump 9 is, by the draw-off pump preceding pipeline air of vavuum pump 10, to cause Pump Suction Nozzle vacuum and transport
Capable, culvert pipe formula diversion increased pump preceding pipeline length, increase gas in pipelines amount, therefore by the vacuum-pumping tube pipe of vavuum pump 10
Footpath is changed to Φ 50mm by original Φ 25, substantially reduces the opening time of centrifugal pump 9, enables the normal work of centrifugal pump 9.
Contain substantial amounts of organic matter in Yellow River mud, such as in long-term deposition diversion culvert pipe 2, it will produce mud hardened existing
As therefore, the utility model is adopted the following technical scheme that：
In order to prevent dirt from entering, circle is set outside water intake 3 and blocks dirty cage 4, the steel for blocking dirty cage 4 by the spacing 2cm of Φ 6
Muscle is arranged to make up, and blocks dirty cage 4 and is placed in river bed, prevents the suction of the debris such as pasture and water.
The far water source of the diversion culvert pipe 2 is inclined by 2% gradient to river course, with reduce as far as possible in diversion culvert pipe 2 water and
Silt, then 45 ° of side slope stretches to river bed along the river, and the bottom of diversion culvert pipe 2 sets water intake 3, and pump is conducive to silt with water after stopping transport
Backflow.
Recoil mouth 6 is provided with the bending intersection of diversion culvert pipe 2, erosion and deposition can be carried out using portable pump during 3 silting of water intake.
The diversion culvert pipe 2 is provided with many places sediment ejection opening 5, if diversion culvert pipe 2 is more long, sediment ejection opening 5 is rationally set, to draw
The desilting of water culvert pipe provides convenience.
The velocity in pipes of control diversion culvert pipe 2 is not less than 1.0m/s, and outstanding Sha Suishui enters field, do not result in mud in diversion culvert pipe 2
Sand alluvial.
Embodiment：
Certain irrigation areas downstream, 1.01~10kg/m of diversion mean sediment concentration3, 3541 mu of irrigated area is related to 3 villages,
