Abstract

The utility model relates to an irrigation and drainage pumping station with a mixing flow pump, which is composed of a controller, a motor, a water pump, a water tank with the functions of irrigating, draining and dropping, etc. The pumping station has three functions of irrigating, draining and dropping and has the advantages of unique structure, high practicality, convenient construction and low cost, and energy saving and low consumption can be realized by the measures of reducing tubes, reducing elbows, removing foot valves, etc. The utility model can be widely used for the irrigation and drainage for farmlands in plain and swale areas.

Description

Irrigation and drainage pumping station with mixing flow pump

The utility model relates to a kind of electric power mixed flow pumping plant that is used for farmland discharging-irrigating.

At present, the small-sized mixed flow pumping plant that is used for drought resisting, water drainage is bank pump and bow pump mostly, owing to adopt the longer pipe road, bottom valve and bend pipe are arranged in addition, cause water yield little, the energy consumption height, of poor benefits, and above-mentioned pumping plant all will pour into a certain amount of water because the defective in the design mostly goes up can only be used for separately irrigating or water drainage before each the startup in pump, construction, use be inconvenience all.

The purpose of this utility model by the improvement to existing bank pump, provides a kind of and realize water drainage in same pumping plant, irrigates, and falls three kinds of functions in advance, and can reduce civil works, improves unit efficiency, easy to operate novel mixed flow pumping plant.

Accompanying drawing is plane (overlooking) figure of this pumping plant, and the sequence number of marking is expressed as follows respectively in the accompanying drawing:

1, gate; 2, gate; 3, gate; 4, gate; 5, trashrack gate; 6, non-return sluice gate; 7, water channel; 8, water channel; 9, the water pump well that falls; 10, motor; 11, mixed-flow pump; 12, irrigation water turn pool; 13, row's precipitation turn pool; 14, pond; 15, go out the moisture flow pond; 16, the current pond is every a wall; 17, controller switching equipment; 18, machine room.

Below in conjunction with accompanying drawing technical solution of the present utility model is described:

Machine room 18 is built in the bank near the water source, controller switching equipment 17, motor 10, the water pump well 9 that falls, mixed-flow pump 11 is placed in the machine room 18, row irrigation gate 1, groove is made on 2,3,4 dual-sides and base, during use, with gate 1,2 plug gate sheet, and the water at water source is through trashrack gate 5, water channel 8 enters out the inlet channel below the moisture flow pond 15, starter motor 10, drive mixed-flow pump 11 work, water is just extracted out from mixed-flow pump 11 like this, and through going out moisture flow pond 15, the current pond is every a wall 16, gate 3, irrigation water turn pool 12, water channel 7, non-return sluice gate 6, advance irrigation canal, so just realized the purpose of irrigating.

Gate 3,4 is plugged gate sheet, and field ponding (flood) is through row's precipitation channel, by non-return sluice gate 6, and water channel 7, gate 1 enters out the inlet channel below the moisture flow pond 15.Starter motor 10 drives mixed-flow pump 11 work, and water is just discharged from mixed-flow pump 11 like this, and through going out moisture flow pond 15, the pond is every a wall 16, and gate 2 is arranged precipitation turn pool 13, water channel 8, and trashrack gate 5 enters Wai He, has so just realized draining flooded fields or falls the purpose of stain.

Embodiment: machine room 18 is a common brick stone structure one-storey house, pond 14 is brick, smear cement mortar outward, water channel 7,8 is 0.9 meter concrete prefabricated culvert pipe of diameter, fall well 9 of water pump is built for steel concrete and is formed, water pump 11 is 14 inches mixed-flow pumps, and motor 10 is 22 kilowatts of three phase squirrel cage motors, and gate sheet is that 5 cm thick planks are made.

Claims (3)

1, a kind of mixed-flow pump drainage and irrigation station, by machine room 18, controller switching equipment 17, motor 10, water pump 11 compositions such as grade is characterized in that: this pumping plant has three millponds 14 and the water pump well 9 that falls.

2, a kind of mixed-flow pump drainage and irrigation station according to claim 1 is characterized in that: be provided with four row irrigation gates 1,2,3,4 and turnover pond 7,8 in the pond 14.

3, according to claim 1,2 described a kind of mixed flow pumping plants, it is characterized in that: groove is made on the dual-side and the base of gate 1,2,3,4.
