[embodiment]

Shown in Fig. 3,4,5, one preferred embodiment of the utility model watermill type aerator comprises one and can be floated on scaffold 20, on the water surface 200 and be located at gear unit 30, on this scaffold 20 and be arranged at cover cap 50, two scoop-wheels 60 that motor 40, on this scaffold 20 just can be covered with this motor 40 and gear unit 30, and a dissolved oxygen unit 70.

This gear unit 30 comprise first output shaft 32 that the body 31, of a hollow extends towards this water surface 200 from this body 31, one with these first output shaft, 32 perpendicular second output shafts 33, a bearing 34, reach a waterproof ring 35.

This first output shaft 32 is worm screws, has first linkage section 321 towards this water surface 200, and second linkage section 322 in contrast to this first linkage section 321, the end of this first linkage section 321 is formed with a long recess 323, reaches one through the bolt part 324 of these first linkage section, 321 ends to connect this dissolved oxygen unit 70.

This second output shaft 33 is fluted discs that are meshed with this first output shaft 32, has two and extends this body 31 outer and reciprocal transmission sections 331.

This bearing 34 is first linkage sections 321 that are arranged at this first output shaft 32, and in this preferred embodiment, this bearing 34 is thrust bearings.

This waterproof ring 35 is to be arranged at these bearing 34 1 sides and towards this water surface 200, this waterproof ring 35 is to be connected with these body 31 driving fits, whereby to reach the function of waterproof.

This motor 40 is the tops that rise sheer from this gear unit 30, and is connected in second linkage section 322 of this first output shaft 32, these first output shaft, 32 rotations of interlock whereby.

Described scoop-wheel 60 is the transmission sections 331 that are arranged in this second output shaft 33 respectively, and respectively this scoop-wheel 60 comprises that majority can be towards the blade 61 of these water surface 200 contacts.

Shown in Fig. 4,5,6, this dissolved oxygen unit 70 comprises that one is sheathed on the appendix 71 of first linkage section 321 of this first output shaft 32, and the two row's leaf groups 72 that are installed on this appendix 71.

This appendix 71 is by this

bolt part

324 and 321 windings of first linkage section, and be from this water surface more than 200 and extend into this water surface 200, this appendix 71 has an air admission hole 711 that is positioned on this water surface 200, and one extends to the inlet channel 712 of this water surface below 200 from this air admission hole 711.

Described row's leaf group 72 is to be positioned at this water surface below 200, and respectively has most aeration passages 723 and link to each other with this inlet channel 712, and respectively this row's leaf group 72 has a blade 721, reach one and this blade 721 involutory and form the lower blade 722 of aeration passage 723.

Cooperate shown in Figure 7, whereby, when these motor 40 runnings, just can by this first, two

output shafts

32,33 drive scoop-wheel 60 and these row's leaf group 72 rotations simultaneously, when this arranges leaf group 72 when rotated, the inner air of this appendix 71 can be because of high speed rotating and to external diffusion, make 71 inner moments of this appendix form low pressure, so air will be in regular turn via this air admission hole 711, this inlet channel 712, described aeration passage 723 and diffuse into this water surface 200 bottoms, and can the air of diffusion be broken up by this rotation of arranging leaf group 72, form and the well-mixed usefulness in subjacent waters.

And when importing air, arrange leaf group 72 in undersurface rotation via this again, and scoop-wheel 60 is in the rotation disturbance of water surface, so just can make the water body in upper and lower layer waters form convection current, and in the convection process of upper and lower water body, make water temperature, the dissolved oxygen of upper and lower layer can both reach alternate cycles, therefore, for whole waters, can allow upper and lower water body produce convective exchange, and in whole convection process, also make water temperature produce the effect of homogenising, dissolved oxygen expanded rangeization synchronously.

So, can find from above-mentioned explanation, because the degree of depth of dissolved oxygen, range can be by the running of the utility model watermill type aerator and is promoted, and can also produce, the exchange cycles of following current, so under running of the present utility model, the fish of being cultured in the waters just anoxia phenomenon can usually not occur, and the bottom mud also can be because of containing the oxygen abundance in the water, make microorganism fully organic matter to be decomposed, so just be difficult for having ammonia, peculiar smell and germ grow, therefore, no matter the utility model watermill type aerator is aspect the effect of dissolved oxygen, is still doing aspect the water body exchange cycles, high speed can both be arranged, deeply, wide effective utilization, in order to the solution of dissolved oxygen problem in the waters to be provided, the effect that general really waterwheel is reached is better, and reaches application target of the present utility model and function.

What deserves to be mentioned is, for waterwheel in the past, as long as change for being gear unit 30 of the present utility model, set up this dissolved oxygen unit 70 again, then can reach as above identical effect equally, just under original agent structure, need not do significantly change, just can be suitable for suitable convenience.
