The drive unit of described main shaft impeller comprises internal box and the some water orifices of being located on the internal box of being located at outer casing inside, the blade of described main shaft impeller is between outer casing and internal box, internal box bottom or side are connected with water intake, outer casing is provided with effluent mechanism, and described effluent mechanism is the form of the water outlet that is connected with the outer casing side.

Described water orifice is along distributing on the excircle 360 degree directions of internal box, and high pressure water sprays from water orifice, impacts the main shaft impeller from inside to outside, thereby drives the fan rotation on the main shaft.

Each is individual part described water orifice, and the employing plug-in type is installed, and adopts the baffle plate sealing to insert mouth when not assigning; The sectional shape of described water orifice is a rectangle; The quantity and the cross-sectional sizes of described water orifice are set according to actual needs.

The angle of the water spraying direction of described water orifice and the circular arc tangential line of its position is between 0 °～60 ° or 120 °～180 °.

Described effluent mechanism is the form of spreading hydrophone, and it and water turbine adopt integrated design, and such design makes the volume of whole device littler, is more conducive to the ventilation in cooling tower space; Described spread hydrophone comprise spread the hydrophone impeller and with spread that the hydrophone impeller is connected spread the hydrophone water pipe.

Described water intake inserts from the internal box bottom vertical, and the described hydrophone impeller that spreads is nested in main shaft impeller outside; Perhaps water intake inserts from internal box side level, spreads hydrophone impeller correspondence and is located at main shaft impeller below.Aforesaid way needs the concrete condition according to different cooling tower inlet and outlet systems, can MIN transformation original system with how as the foundation of selecting.

Described spreading between hydrophone impeller and the main shaft impeller is provided with the guiding swash plate.

The described hydrophone water pipe lower end of spreading is provided with several short tubes vertically downward.

With respect to prior art, the utlity model has following beneficial effect: (1) has cancelled motor and reducer arrangement, has saved electric power; (2) make full use of water and spray remaining inertia behind the impeller, drive and spread the hydrophone rotation, reach the purpose of evenly spreading water; (3) because the integrated design of spreading hydrophone and water turbine makes the volume of whole device littler, save the height in space, increased the stroke that hot water falls, thereby improved the efficient of cooling; (4) be provided with short tube, the water phenomenon of having avoided wafing owing to spread hydrophone water pipe lower end.(5) owing to adopt the mode of injection water from inside outwards, so water intake can be located at side or bottom, is convenient to the renovation and utilization to existing cooling tower.
