Fig. 1 is the perspective view of the utility model;

Fig. 2 is the structural representation sketch of the utility model.

Embodiment:

With specific embodiment the utility model is further described below, referring to Fig. 1-2:

Frequency conversion type is ploughed aerator in water, and motor 10 is erected on the buoyancy aid, and the output shaft 80 of motor 10 is connected with reduction gear housing 60, and the output shaft 30 of reduction gear housing 60 is connected with impeller 20, and described motor 10 is electrically connected with computer frequency-variable controller 40.

Above-mentioned buoyancy aid is the annular buoyancy aid, also can be ship type buoyancy aid, or ball float 50, and described motor 10 is erected at the middle part of buoyancy aid through support.As: ball float 50 circumferentially is distributed on outside the motor 10 through support 130.Ball float 50 floats over water surface, and motor 10 can not contact with water.

Output frequency/the rotating speed of above-mentioned computer frequency-variable controller 40 is provided with high speed oxygenation 110 and ploughs 120 two grades in water with low speed, and is simple to operation.Carry out speed governing with computer frequency-variable controller 40, and computer frequency-variable controller 40 has been carried out the bionical and artificial intelligence simplification of lot of test, improve the safety of system, the bionical operating mode (rotating speed/frequency) of the computer frequency-variable controller 40 of development has only two grades; Also can be set as stepless speed changing type: through knob stepless speed regulation.

Above-mentioned computer frequency-variable controller 40 is provided with the interface of more than one reception wireless remote control signal to realize the closed loop fully automatic operation; As: water body dissolved oxygen meter interface, weather gauge control unit interface or handset port; Also can be other wireless remote control signaling interfaces; I.e. starting high speed 120r/min oxygenation when anoxic, 5～17r/min ploughs water running to purify water at ordinary times.

The output shaft 30 of above-mentioned reduction gear housing 60 is provided with speed clutch 100, and the extended type that is connected with the high speed clutch on the speed clutch 100 is ploughed water plate 90.Speed clutch 100 is ploughed water plate 90 to be applicable to the more big area water surface (as more than 20 mu) with extended type, and when low speed, speed clutch 100 connects the cultivated water plate 90 of extended type and ploughs the water operation; After impeller 20 rotating speeds surpassed 20r/min, speed clutch 100 was thrown off cultivated 90 of the water plates of extended type and is carried out the oxygenation operation.

Above-mentioned motor is threephase asynchronous machine or single-phase machine, has abandoned complicated reduction gear arrangement of common cultivated water machine and expensive direct-current machine type of drive.

Be example with the 1.5KW paddle aerator below: normal oxygenating machine rotating speed 120r/min, computer frequency-variable controller output frequency 50Hz this moment (50HZ corresponding 1440 changes, and 1HZ corresponding about 30 changes)

T=9550P/n:T is torque, and P is a power, and n is a rotating speed,

Under traditional speed reduction unit situation, T=9550 * 1.5/1440=9.95N.M;

Impeller speed is got 120r/min, and the system slowdown ratio is: 1440: 120=12: 1;

When requiring wheel speed to be 10r/min; Motor speed then is 12 * 10=120r/min;

Then required power=T * n/9550=9.95 * 120/9550=0.125KW;

Energy-conservation (1.5-0.125)/1.5=90%

Survey: measured current 1.4A when 10 rev/mins of runnings of computer frequency-variable controller 40 low frequencies, voltage is 60V.

P＝60V×1.4A＝84W

Energy-conservation: (1.5KW-0.084KW)/1.5=94%;

As with this rotation speed operation 24H power consumption=84 * 24=2.016kWH, 2 degree only.

It is thus clear that power consumption was very low when common oxygenating machine was done to plough water treatment at the computer frequency-variable controller that adds the utility model 40, that is to say that energy-saving effect is obvious.

Oxygenating machine invention has obtained bigger promotion and application in all parts of the world over 40 years; After particularly getting into state subsidies in recent years; Every year, only the newly-increased various oxygenating machines in coastland reached 1,000,000; In culturing whole process, the oxygenation at full speed more than 2 hours of all must starting shooting every day, the other times section if can be ploughed the water operation; Can economize medicine (reducing medication), economize characteristics such as bait (planktonic organism accelerates multiplication in the water body is for prawn provides natural living bait), raising output and quality thereby reduce the bottom pollutent and purify water.And can reduce high speed oxygenation required time, play the effect of energy efficiency.

The 29th second of national energy method also clearly stipulated: the blower fan load of the pumps should adopt electronic speed regulation.

The foregoing description is merely one of preferred embodiment of the utility model; It is not the practical range that limits the utility model with this; So: the equivalence that all shapes according to the utility model, structure, principle are done changes, and all should be covered by within the protection domain of the utility model.
