Before the water pump is used for pumping water, the cabin door 5 can be opened, the limiting sliding sleeve 16 slides down from the knob 15, the knob 15 is rotated according to the dial 18, the driving bevel gear 12 is driven to rotate through the control shaft 13, the adjusting shaft 7 is driven to rotate through the driven bevel gear 11, the engaged steering gears 10 are driven to rotate through the adjusting gears 8, the blades 20 are driven to rotate through the steering shafts 9, the angle of the blades 20 is adjusted, the water pumping quantity of the water pump is manually adjusted and controlled in a mode other than the adjusting power of the water pump motor 3, the energy loss and the abrasion of the water pump motor 3 when the power of the water pump motor 3 is adjusted are reduced, after the adjustment is finished, the limiting sliding sleeve 16 slides onto the knob 15 again, the limiting strip 19 is clamped into the limiting groove to limit the knob 15, the adjustment and control is finished, and the bolt 26 can also slide out of the slot on the limiting plate 23 to relieve the limitation of, then the rotating handle 22 is rotated to drive the extension blade 21 to slide out, so that the area of the blade 20 is increased, namely the water diversion amount of the blade 20 rotating for a circle is increased, the water pumping amount of the water pump is manually increased, the waste of electric energy is reduced, and after the adjustment is finished, the bolt 26 can be inserted into the slot again under the elastic action of the second limiting spring rod 25 to limit the rotating handle 22 and the extension blade 21.

This water pump stable in structure, setting up of balancing piece 42 can be when the high-speed rotation of rotary drum 6, balance the control unit, make the weight of rotary drum 6 both sides keep unanimous, make the operation of rotary drum 6 more steady, the removal and the fixing of this water pump are convenient for in setting up of universal auto-lock wheel 24, and the setting of damping spring pole 41 can cushion and absorb the vibrations that this water pump during operation produced, has played the effect of shock attenuation and noise reduction, has improved the stability of this water pump work.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
