Abstract
A kind of semi-cylindrical bucket hydraulic turbine, including the runner (2) being installed on central rotating shaft (1), along the bucket (3) of runner circumference uniform distribution installation, the bucket (3) is semi-cylindrical bucket, including semicircular arc bottom plate (3a) and is welded in the semicircle end plate (3b) of bottom plate inner end.The utility model can greatly increase the impact effect of water flow, and bucket catchment after stability under loading, be unlikely to deform offset and damage.Semi-cylindrical bucket water capacity is big, is suitable for ultralow and compared with low head power generation, is remarkably improved generating capacity and generating efficiency, reduces cost of power station.
Description
Technical field
The utility model belongs to the hydraulic turbine structure technical field of water-energy generating electricity machine equipment.
Background technique
The hydraulic turbine is the key device of water-energy generating electricity, the planform and water capacity of bucket directly affect generating capacity and
The service life of efficiency and the hydraulic turbine.Existing hydraulic turbine bailer is various informative, such as flute profile, zigzag, wooden dipper shape, bucket shape
Deng there are also the not set bucket of the hydraulic turbine, but impeller, blade being arranged, the runner of the hydraulic turbine is driven by the impact of waterpower
Rotation, to drive electrical power generators.Existing hydraulic turbine bailer all has that stress is unreasonable, water capacity is not big enough asks
Topic, affects generating capacity and efficiency, reduces the service life of the hydraulic turbine.
Summary of the invention
The purpose of this utility model is to solve the shortcomings of the prior art, provide a kind of reasonable stress, long service life,
The semi-cylindrical bucket hydraulic turbine that water capacity is big, generating capacity and generating efficiency are high.
The purpose of this utility model is achieved through the following technical solutions:
A kind of semi-cylindrical bucket hydraulic turbine is installed including the runner being installed on central rotating shaft along runner circumference uniform distribution
Bucket, the bucket be semi-cylindrical bucket, including semicircular arc bottom plate and the semicircle end plate for being welded in bottom plate inner end.
The semi-cylindrical bucket that the utility model uses, bottom plate are arc-shaped, and the water flow of entrance is arcuately converged downwards
Collect in arc-shaped bucket, can greatly increase the impact effect of water flow, and bucket catchment after stability under loading, be unlikely to deform offset
And damage.Semi-cylindrical bucket water capacity is big, is suitable for ultralow and compared with low head power generation, is remarkably improved generating capacity and power generation
Efficiency reduces cost of power station.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of semi-cylindrical bucket；
Fig. 3 is the operation schematic diagram of the utility model.
Specific embodiment
The semi-cylindrical bucket hydraulic turbine as shown in Figure 1, including the runner 2 being installed on central rotating shaft 1, along runner circumference
The bucket 3 uniformly installed.As shown in Fig. 2, the bucket 3 is semi-cylindrical bucket, including semicircular arc bottom plate 3a and it is welded in
The semicircle end plate 3b of bottom plate inner end.
As shown in figure 3, the water flow A poured from top or lower part is impacted in semi-cylindrical bucket 3 when utility model works
Arc-shaped bottom plate 3a on, water flow is swimmingly pooled to bottom plate center along arc-shaped bottom plate, forms the impulse force of concentration, pushes runner
Quick rotation, to drive generator 4 to work by belt pulley 5.On the one hand arc-shaped bottom plate can reduce the power that is hit, another
Water flow can be pooled to rapidly bucket center by aspect, form powerful impact force, make runner quick rotation.If water flow is from top
It pours, the big water capacity of semi-cylindrical bucket can also promote runner quick rotation.
