In order to achieve the above objects and other related objects, the utility model provides a kind of semifixed drainage pumping stations of well shaft type, Including fixed part and movable part；Wherein,

The fixed part includes inspection shaft, outlet pipe, drainage culvert and sluice；The drainage culvert and sluice is fixed on gutter with water drainage River course junction, including culvert, gate, headstock gear, culvert pass through River Embankment, meet river surface for aliform pitched work and stone-laying River bottom protection, and gate and headstock gear are set；It is pitched work, stone-laying river bottom protection at back of the body river surface culvert import, and is connected with gutter；Institute State inspection shaft to be bordered on the river face side positioned at culvert, including positioned at the pit shaft of the first half, positioned at top walling crib and well lid and be located at The inlet well of lower half；The pit shaft side connects outlet pipe, and the inlet well side is connected with culvert；The wellbore bottom It is provided with snap ring；

The movable part includes submersible axial flow pump, dislocation generation unit；The submersible axial flow pump includes cover plate, flange Disk, the pump housing, water inlet, cover plate are connected with the pit shaft flange and are provided with rubber seal；The pump housing is located at the pit shaft bottom On portion, snap ring；The dislocation generation unit includes starting cabinet, generator, diesel engine, motor vehicle.

As described above, the semifixed drainage pumping stations of well shaft type of the present utility model, have the advantages that：

Using the utility model, difficulty of construction can be reduced, reduce construction investment and operating cost, and due to reducing Pump house, transformer room, management house etc. are built, and forever take up an area without taking, non-flood period, and move portion grades relevant device can be external Hire out or for field irrigation, improve utilization rate of equipment and installations, increase project benefit.
