The power mode of existing axial flow reflux pump adopts submersible motor that power is provided, so just higher to the seal request of power motor.Because submersible motor is worked under water, so its cooling is the self cooling mode of outer shell, this just makes the temperature of water unsuitable too high.
In sum, axial flow reflux pump of the prior art exist turbulent area little, inconvenience is installed, the sealability of power motor is required to easily shortcoming affected by environment of high, heat radiation.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of axial flow reflux pump, by changing reflux pump working method, optimizing its structure, reaches the object that expands turbulent area, reduces the sealability requirement of power motor simultaneously and strengthens its heat dissipation potential.

Reflux assembly is axially connected with power motor, adopts pump shaft as power transmission member simultaneously, makes the impeller can be in the work of the position away from from power motor.Just can allow thus axial flow reflux pump work on vertical direction, power motor is positioned on horizontal plane, and impeller is embedded under horizontal plane.The working method of axial flow reflux pump is changed.The effect bringing thus can not only increase turbulent area, and can allow power motor in air, so just can reduce the sealing requirements to power motor, can increase by the mode of wind-cooling heat dissipating its heat dispersion simultaneously.
As of the present invention preferred, described support sole both sides are connected with buoyancy tank.By the supporting effect of buoyancy tank, this axial flow reflux pump just can float on the water surface, can simplify fitting operation on the one hand, the impact that not changed by fluctuation in stage while making on the other hand the work of axial flow reflux pump, random mobile position, thereby can better reduce, stir dead angle, strengthen its ability that is applicable to difformity pond.
As of the present invention preferred, described outlet pipe is horn-like, and this end diameter that described outlet pipe is connected with intake pipe is less than outlet pipe the other end diameter.This structure can increase the radiation surface of axial flow reflux pump, for reducing stirring dead angle, has important function.
The present invention adopts technique scheme: axial flow reflux pump structure is optimized, and forms thus the pump housing that draws water and dives beneath the water, the working method that power motor surfaces.Current direction of propulsion, on vertical position, has increased turbulent area so greatly.Power motor is positioned on the water surface, can realize wind-cooling heat dissipating, has avoided water temperature to change the heat radiation process of power motor is impacted, and so not only goes for different water temperature environment, and has extended the working life of power system.Meanwhile, reduce the sealing requirements to power motor, contributed to reduce the manufacture cost of equipment.
