Abstract

The utility model provides a hydro-turbine, comprising two or more sets of turbines (2), (3) and (4); wherein, the turbines and a water channel are positioned around the inner edge of the hydro-turbine; a plurality of vanes are positioned on the salient outer flank of a U-shaped disk impeller; a common wheel shaft (5) is used by the impeller of each turbine; a water outlet pipe (8) of one turbine is a water inlet pipe (9) of the other turbine. The utility model has the advantages of full utilization of relatively small hydropower resources, higher power, and suitability for power generation in mountain areas with small water volume.

Description

Water turbine

Technical field the utility model provides a kind of hydrodynamic apparatus, specifically, is a kind of water turbine.

The existing water wheels unit of background technique generally adopts mode in parallel, and this mode need be utilized hydrodynamic force fully under the bigger situation of the water yield, improves power.But under the condition of water yield circlet border, this mode is not really suitable, as under the very little condition of water flows such as mountain stream, streams, may not adopt this mode.For example, be used for generating,, can not make full use of relative water resource than water if adopt unit running usually.The very inclined to one side mountain area of keeping away in the geographical position, mountain stream, streams are seen how to make full use of these hydrodynamic force resources more, and be to improving mountain people's production, living condition, significant.

The purpose of this model utility of summary of the invention just is to provide a kind of water turbine, and it can make full use of less hydrodynamic force resource, improves power.

For achieving the above object, the water turbine that the utility model provides has two or more turbines, the shared wheel shaft of the impeller of each turbine, water channel in each turbine is arranged on the turbine inside edge around shape, impeller is the U-shaped disk, and wheel blade is located at the disk lug along the outside, during installation, the wheel blade of impeller partly stretches in the turbine water channel, and the outlet pipe of last round of machine is the intake pipe of next turbine.

For improving the revolution of this turbine output shaft, the utility model is in the end set up the gear accelerating unit between the impeller shaft of a turbine and the functional disc, and the input shaft of this accelerating unit is the impeller wheel shaft, output shaft connection function dish.

The utility model improves power because form that each turbine of employing is connected mutually and special water channel and wheel blade design can make full use of hydrodynamic force, is specially adapted to the less natural condition generating of the mountain area water yield etc.

Description of drawings Fig. 1 is the utility model complete machine appearance assumption diagram

Fig. 2 is provided with schematic representation for the utility model water channel

Fig. 3 is the utility model blade wheel structure schematic representation

Embodiment such as Fig. 1, Fig. 2, shown in Figure 3, the water turbine that the utility model provides has frame (1), three groups of wheels (2), (3), (4), wheel shaft (5), functional disc (6), wheel (2) intake pipe (7) and outlet pipe (8) is housed, outlet pipe (8) is connected turbine (3), the outlet pipe (9) of turbine (3) is connected turbine (4), and turbine (4) is connected to outlet pipe (10).

The water channel of each turbine of the utility model (11) is around being arranged on the turbine inside edge, impeller (13) is the U-shaped disk, wheel blade (13) is arranged on the outside on disk lug edge, and impeller (12) is fixed on the wheel shaft (5) by impeller set (14), and each organizes the shared wheel shaft of turbine (5).The output shaft (5) of turbine (4) connects gear accelerating chamber (16), output shaft (17) the connection function dish (15) of gear accelerating chamber (16).
