Abstract

The utility model relates to a large-impeller gearbox water-turbine generator set which comprises a hydroturbine and a generator. A gearbox is arranged between the hydroturbine and the generator; the input end of the gearbox is connected with the output end of the rotating shaft of the hydroturbine; the output end of the gearbox is connected with the input end of the generator; and the hydroturbine is a large-impeller hydroburbine. The large-impeller hydroburbine can obtain a larger torque force when water flow rate is small and can change the rotate speed through the gearbox to match with the rotate speed of the generator, so the generated energy is increased. The utility model has the advantages of simple structure and strong practicality and is suitable for a small hydropower station with a small water flow rate increasing the generated energy.

Description

The big impeller gearshift case hydro-turbo generator set

[technical field]

The utility model relates to a kind of hydraulic turbine generator, relates in particular to a kind of big impeller gearshift case hydro-turbo generator set that gearbox is installed between water turbine that strengthens impeller and generator.

[background technique]

Small hydropower station has obtained extensive use in China, and small hydropower station is often anxious because of the little problem of water flow, and how making the little and little small hydropower station of generated energy of water flow can send out electricity more on the basis of original water flow is exactly problem to be solved in the utility model.

[model utility content]

In order to overcome the above-mentioned shortcoming of prior art, a kind of by improving the big impeller gearshift case hydro-turbo generator set that generator speed increases its generated energy thereby the utility model provides.

The technological method that its technical problem that solves the utility model adopts is: a kind of big impeller gearshift case hydro-turbo generator set, comprise water turbine and generator, between water turbine and generator, gearbox is housed, the input end of described gearbox links to each other with water turbine rotating shaft output terminal, and this gear box output end links to each other with the generator input end; Described water turbine is big impeller water turbine.

Described gearbox gear is a canine tooth wheel driving pinion structure.

The beneficial effects of the utility model are: big impeller water turbine hour can obtain big torsion in water flow, changes its rotating speed by gearbox again, and itself and generator speed are complementary, thus the raising generated energy.The utlity model has simple in structure, practical characteristics, be applicable to that the little small hydropower station of water flow improves generated energy.

[description of drawings]

Fig. 1 is a structural representation of the present utility model; Among the figure: 1-water turbine, 2-gearbox, 3-generator.

[embodiment]

Below in conjunction with drawings and Examples the utility model is further specified: referring to Fig. 1, a kind of big impeller gearshift case hydro-turbo generator set, comprise water turbine 1 and generator 3, between water turbine 1 and generator 3, gearbox 2 is housed, water turbine 1 adopts big impeller water turbine, also can obtain big torsion at a water flow hour big impeller water turbine, water turbine 1 rotating shaft output terminal is linked to each other with gearbox 2 input ends, gearbox 1 gear is a canine tooth wheel driving pinion structure, improve its rotating speed by gearbox 2, itself and generator 3 rotating speeds are complementary, again these gearbox 2 output terminals are linked to each other with generator 3 input ends, thereby improve the generated energy of generator, have simple in structure and practical characteristics, be applicable to that the little small hydropower station of water flow improves generated energy.
