Abstract
The utility model discloses a water wheel power generation device, which has the characteristic that the power generation efficiency can be improved. The water wheel power generation device comprises an output shaft and a plurality of fan blades connected to the output shaft, wherein each fan blade is provided with a buoyancy device. Because the fan blades are provided with the buoyancy devices, when the fan blades encounter larger resistance in water flows, the fan blades can rotate quickly through the upward buoyancy of the buoyancy devices so as to improve the power generation efficiency of the water wheel power generation device; and by the blades on the fan blades, the blades can be switched between opening and closing so as to not only ensure the fan blades to rotate under the impact of water flows but also ensure small resistance on the fan blades and the improvement on the power generation efficiency, and the water wheel power generation device is particularly suitable for being popularized and applied in water wheel power generation equipment.
Description
Technical field
The utility model relates to a kind of power generating equipment, is specifically related to a kind of waterwheel power generation equipment.
Background technique
At present, waterwheel power generation equipment mainly includes an output revolving shaft and is fixed on flabellum on the output revolving shaft.During work, this waterwheel power generation equipment is placed current, under the percussion of current, output revolving shaft is rotated, finish power generation process flabellum.But existing waterwheel power generation equipment has reduced the efficient of generating because bigger lifting surface area and the gravity of flabellum can produce bigger resistance in rotation process.
The model utility content
Technical problem to be solved in the utility model provides a kind of waterwheel power generation equipment that improves generating efficiency.
The technological scheme that its technical problem that solves the utility model adopts is: waterwheel power generation equipment comprises output shaft and is connected a plurality of flabellums on the output shaft that flabellum is provided with buoyant device.
As optimized technical scheme, described buoyant device is the hollow unit that is arranged on the flabellum end.
Further be, be provided with a plurality of blades in flabellum, described blade two ends are provided with rotating shaft, and blade pass is crossed rotating shaft and is hinged on the flabellum, and blade is connected with power plant.
Further be, described power plant are the motor that is fixedly installed in the flabellum, and the shaft extension end of motor is fixedlyed connected with rotating shaft.
The beneficial effects of the utility model are: be provided with buoyant device by flabellum, when flabellum meets with bigger resistance in current, can flabellum be rotated by the suffered buoyancy that makes progress of buoyant device, thereby improve the generating efficiency of this waterwheel power generation equipment; And the blade by on flabellum, being provided with, blade is switched between unlatching and closure, thereby both guaranteed that flabellum can rotate under the percussion of current, can guarantee that again the suffered resistance of flabellum is less, also guaranteed the raising of generating efficiency, be particluarly suitable for applying in the water wheel generating set.

Be labeled as among the figure: output shaft 1, flabellum 2, buoyant device 3, blade 4, motor 5, rotating shaft 6.
Embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As shown in Figure 1, waterwheel power generation equipment of the present utility model comprises output shaft 1 and is connected a plurality of flabellums 2 on the output shaft 1 that flabellum 2 is provided with buoyant device 3.In Fig. 1, be that true origin is set up system of coordinates with the center of circle, the cross section O of output shaft 1, during work, the flabellum 2 of third quadrant is subjected to begin to rotate after the impact of current in the system of coordinates, and drives output shaft 1 and rotate, and finishes power generation process.After flabellum 2 moves to four-quadrant from third quadrant, flabellum 2 is subjected to the resistance of current to begin to increase, at this moment, because flabellum 2 is provided with buoyant device 3, can be by the suffered buoyancy that makes progress of buoyant device 3, flabellum 2 is upwards rotated, thereby improved the generating efficiency of this waterwheel power generation equipment.
In the above-described embodiment, buoyant device 3 can be to adopt density to make less than the solid material of water density, and as timber, plastics etc., as preferred embodiment, described buoyant device 3 is for being arranged on the hollow unit of flabellum 2 ends.Because the inside of this buoyant device 3 is hollow-core construction, has buoyancy effects preferably in current, no matter adopt which kind of material all can, preferably select for use steel to make certainly, can improve structural strength.
In the above embodiment, flabellum 2 can be an overall structure, but when flabellum 2 is in first, second and four-quadrant among Fig. 1, can cause bigger resistance, therefore, for reducing the resistance in flabellum 2 movement processes, as preferred embodiment, in flabellum 2, be provided with a plurality of blades 4, described blade 4 two ends are provided with rotating shaft 6, blade 4 is hinged on the flabellum 2 by rotating shaft 6, and blade 4 is connected with power plant.In the working procedure, when flabellum 2 is arranged in the third quadrant of figure 1, its structure such as Fig. 2 and shown in Figure 3, promptly the blade 4 in the flabellum 2 is in closed state, makes that flabellum 2 can be more abundant at the percussion lower stress of current; And after the third quadrant of flabellum 2 from Fig. 1 moves to the 4th, power plant work, drive vane 4 is rotated, and makes blade 4 be in opening state (being to have bigger spacing between adjacent two blades 4), its structure such as Fig. 4 and shown in Figure 5, at this moment, the resistance minimum that blade 4 is born can guarantee the quick rotation of flabellum 2, after second quadrant of flabellum 2 from Fig. 1 moves to third quadrant, power plant work, drive vane 4 rotations also are in closed state.So periodic duty can guarantee the high-efficient operation of flabellum 2 to improve generating efficiency.
In the above embodiment, the power plant that described drive vane 4 is rotated can be dynamical elements such as oil hydraulic cylinder, and as optimal way, described power plant are the motor 5 that is fixedly installed in the flabellum 2, the shaft extension end of motor 5 is fixedlyed connected with rotating shaft 6, can improve the reliability of control greatly.
