Description
Technical field
The utility model belongs to water supply field in irrigated area in hydraulic engineering, more particularly to a kind of water supply for being applicable height irrigated area
System.
Background technology
To act on reduction water supply cost by gravity flow, more preferably meeting downstream Irrigation Water demand, mountain area medium and small reservoirs one
As be built in the of a relatively high position of physical features.Because soil cultivating condition and landforms limit, mining under reservoir can usually form difference
The high and low irrigated area of elevation, this is to build safe, economic water system to bring no small challenge.
To meet the water demand in the different high and low irrigated areas of elevation, the following two methods of generally use solve at present.First,
It is respectively that high and low irrigated area is supplied water to build independent lying pipe height culvert formula water system and the low culvert formula water system of lying pipe.This method work
High, the independent water system of journey cost adds operational management cost.Second, supplied using the long-range diversion of canalization for high irrigated area
Water, supplied water using horizontal tube water system for low irrigated area.The long-range diversion cost of this method is high, big along journey water loss.On in addition,
High irrigated area crops water demand when reservoir level is too low can not be met very well by stating two methods.
Utility model content
Solves technical problem existing for high and low irrigated area water supply for existing, the utility model is based on systems organization, classification supplies
The thought of water, there is provided a kind of to be applicable height irrigated area and water intaking guarantee degree height, the water system that water supply is flexibly controllable, cost is low.
To achieve the above object, technical scheme is used by the utility model.
The utility model discloses a kind of water system for being applicable height irrigated area.The water system include lying pipe device,
Pumping equipment and culvert pipe.The lying pipe device includes lying pipe, passage, inlet opening, manhole, diversion basin and stilling pool slab, described
Diversion basin sets diversion gate with lying pipe bottom junction.The pumping equipment includes immersible pump, water-supply-pipe and controlling switch.It is described
Culvert pipe includes high culvert pipe and low culvert pipe；The high culvert pipe connection diversion basin, low culvert pipe connect stilling pool slab, and culvert pipe end sets control
Valve.
Further, the diversion basin sets two delivery ports of a water inlet and left and right, water inlet size and lying pipe horizontal stroke
Cross dimensions is consistent；The delivery port of left and right two is connected with lying pipe, high culvert pipe respectively, and both sizes and floor elevation are homogeneous
Together.
Further, the water-supply-pipe uses PVC hose.
Further, the high culvert pipe cross dimension is consistent with delivery port on the right side of diversion basin, and the gradient is：0°~10°.
Different facilities are opened according to different reservoir levels realize water supply when the utility model is run.When reservoir level is higher than diversion basin
During manhole, lying pipe top inlet opening is opened, is irrigated area water delivery by high and low culvert pipe after current divide water via diversion basin；Storehouse water
When position is less than diversion basin manhole, diversion gate is closed, starts pumping equipment water intaking, is high irrigated area water delivery, open lying pipe bottom
Inlet opening is fetched water, and is low irrigated area water delivery；When reservoir level is less than stilling pool slab manhole, starts pumping equipment water intaking, pass through regulation and control point
Gate is flowed, is high and low irrigated area water delivery；Water delivery flow can be regulated and controled jointly by diversion gate and control valve under different reservoir levels.
Compared with the prior art, the beneficial effects of the utility model are embodied in.
1st, guarantee degree of fetching water is high.By opening different water intake facilities, it ensure that different reservoir levels can get irrigation water.
When reservoir level is higher than diversion basin manhole, the water intaking of lying pipe top inlet opening is opened；When reservoir level is less than diversion basin manhole, open
Dynamic pumping equipment water intaking, while open the water intaking of lying pipe bottom inlet opening；When reservoir level is less than stilling pool slab manhole, startup, which is drawn water, to be set
It is on the waiting list water.
2nd, supply water flexibly controllable.On the one hand, water-supply method is flexible, and different reservoir levels open different water intake facilities water intakings,
Realize that water withdrawal is controllable by regulating and controlling inlet opening and immersible pump.On the other hand, carrying capacity control methods are convenient and simple, pass through regulation and control
Diversion gate and control valve opening realize that carrying capacity is flexibly controllable.
3rd, cost is low.On the one hand, high and low irrigated area shares water intaking structure, reduces construction costs；On the other hand, the runtime
Between, water system is concentrated, and is easy to be managed collectively, is reduced administrative staff's workload, and then reduce operating cost.
