Summary of the invention
The problem that invention is to be solved:
When the existing hydroelectric installation shown in Figure 11 being installed and is used in the bigger water route of sectional area, it is necessary to add
The diameter of the rotor 303 of the permanet magnet 304 attached on big periphery.Also, in this case, as shown in figure 12, attach in turning
While the usage amount of the permanet magnet 304 of the peripheral curve of son 303 increases, it is also desirable to make from the periphery of rotor 303 along footpath
Water lubriucated bearing 307a, the 307b the most stepwise arranged, possesses stator 306 and the cooling body of armature winding 305a
315 maximize.
, the generating capacity of hydroelectric installation typically by " K(ratio fixed number) × flow velocity2× flow " represent.
By means of this, it is installed on the water route of high-lift (high flow rate) and low discharge (i.e. due to the relation between high flow rate and low discharge
The water route that sectional area is less) hydroelectric installation generating capacity be installed on low lift (low flow velocity) and the water route of big flow
The generating capacity of the hydroelectric installation in (water route that i.e. sectional area is bigger due to the relation between low flow velocity and low discharge) has
Time have almost no change.In this case, the water route being provided with hydroelectric installation is become from high-lift and low discharge water route
Time more to the water route of low lift and big flow, it is not necessary that the size of engine section also changes.But, shown in Figure 11
In the case of existing hydroelectric installation, according to the increase of the sectional area in be suitable for water route, not only need the large-scale of rotor
Change (heavy caliber), in addition it is also necessary to make from the periphery of rotor the structure along radial direction staircase (water lubriucated bearing 307a, 307b, fixed
Son 306 and cooling structure 315) also maximize (heavy caliber).
Like this, compared with generating capacity, the water route of the bigger low lift of sectional area and big flow etc. is being suitable for existing water
In the case of power generation device, have and not only device entirety also have to be maximized by rotor, and productivity and economy etc.
Relatively low problem.
The present invention proposes to solve such a problem, its object is to provide one to have and is suitable for conduct
Each key element (flow velocity, flow, sectional area etc.) in the water route of object is corresponding and from the viewpoint of productivity, economy and miniaturization
The hydroelectric installation of the structure being suitable for.
The means of solution problem:
In order to solve described problem, according to the installation of certain form of the present invention the hydroelectric installation tool that is used in water route
Standby: to be installed on upstream side pipe arrangement and the downstream pipe arrangement in described water route, it is arranged at described upstream side pipe arrangement with described heldly
Impeller housing between the pipe arrangement of downstream, is configured at the wheel hub of the axis direction of described impeller housing, and with can be at described impeller
Around the axle center of housing rotate form be contained in the impeller in described impeller housing, described wheel hub be divided into rotary hub with extremely
A few stationary hub, described rotary hub is embedded in described impeller, and at least one stationary hub described is relative to described rotation
Wheel hub across predetermined distance ground fixed configurations, sets at least one stationary hub described on the axis direction of described impeller housing
It is equipped with armature, described rotary hub is provided with permanet magnet with the form opposed with the armature of at least one stationary hub described
Excitation or electromagnet excitation.
According to described structure, be formed as such as the rotary hub being provided with the permanet magnet excitation of electromotor being embedded in leaf
On wheel, and the structure of the armature of electromotor is set at least one stationary hub mutually independent with rotary hub.This situation
Under, can be independently engineered/make impeller and master section (rotary hub, stationary hub), can provide simultaneously and achieve correspondence
Each key element (flow, flow velocity, sectional area etc.) suitable scale from the viewpoint of productivity, economy and miniaturization in water route
Hydroelectric installation.
Such as can independently determine generator capacity with the diameter of impeller so that in existing hydroelectric installation
Can be only by impeller relative to the water route (water route that sectional area is bigger) importing more difficult low lift (low flow velocity) and big flow
The design maximized.If illustrating in greater detail, the generating capacity of hydroelectric installation typically by " K(ratio fixed number) × stream
Speed2× flow " represent, therefore it is installed on the water route (water route that i.e. sectional area is less) of high-lift (high flow rate) and low discharge
The generating capacity of hydroelectric installation be installed on low lift (low flow velocity) and the water route (water that i.e. sectional area is bigger of big flow
Road) the generating capacity of hydroelectric installation sometimes do not change much.In this case, using the bigger water route of sectional area as
During applicable object, even without the size of necessity change engine section.But, in the structure of existing hydroelectric installation
In the case of, not only need the maximization (heavy caliber) of rotor to also need to also maximize master section (heavy caliber).With
This is relative, owing to can be independently engineered/make impeller and master section, by master section maximization only therefore need not
Impeller is maximized.
Otherwise, from the water route (water route that sectional area is bigger) of low lift and big flow to the high-lift and water route of low discharge
During (water route that sectional area is less) change applicable object, the generating capacity of hydroelectric installation does not changes much sometimes.This
In the case of, owing to can be independently engineered/make impeller and engine section, the most do not change the size of engine section and only will
Impeller miniaturization.

Structure.By means of this, can be independently engineered/make impeller 5 and master section (rotary hub 4b, stationary hub 4a), simultaneously can
Improve productivity.
For example, it is possible to independently determine the capacity that generates electricity with the diameter of impeller 5, in order to suitable in existing hydroelectric installation
The water route of low lift (low flow velocity) and big flow for importing difficulty (the i.e. sectional area due to low flow velocity and the relation of big flow
Bigger water route) only runner 5 can be designed/makes with maximizing.Illustrating in greater detail with reference to Fig. 5, hydroelectric generation fills
The generating capacities chart put be shown as " K(proportionality constant) × flow velocity2× flow ", therefore at high-lift (high flow rate) and the water of low discharge
The hydroelectric installation of road (that is, the water route that sectional area is less due to the relation between high flow rate and low discharge) the upper installation of 200a
Generating capacity with in low lift (low flow velocity) and the waterpower of the upper installation of water route (water route that sectional area is bigger) 200b of big flow
The generating capacity of TRT does not changes much sometimes.In this case, from the water route of high-lift and low discharge, (sectional area is relatively
Little water route) when the water route change applicable object of low lift and big flow, it is not necessary that the even electromotor of hydroelectric installation
The size of part also changes.But, in the case of the existing hydroelectric installation shown in Figure 11 and Figure 12, along with cutting of water route
The increase of area, not only needs the maximization (heavy caliber) of impeller 303 to be also required to master section (306) and maximizes (greatly
Bore).On the other hand, in the case of possessing the hydroelectric installation 100 of structure discussed above, can be independently engineered/
Making impeller 5 and master section (rotary hub 4b, stationary hub 4a), the sectional area therefore corresponding to be suitable for water route only needs
Impeller 5 is maximized.
Otherwise, from the water route (water route that sectional area is bigger) of low lift and big flow to the high-lift and water route of low discharge
During (water route that sectional area is less) change applicable object, the feelings that the generating capacity of hydroelectric installation does not changes much sometimes
Condition.In this case, can be independently engineered/make impeller 5 and master section (rotary hub 4b, stationary hub 4a), therefore
Vary without the size of engine section only by impeller 5 miniaturization.
Separately, in the case of the water route (water route that sectional area is less) of low lift and low discharge, can be by impeller 5 and electromotor
Part miniaturization simultaneously, but owing to can be independently engineered/make impeller 5 and master section, therefore to obtain sending out of abundance
Master section can only be maximized by capacitance.
Also, easily load and unload master section from impeller 5, the manufacturing process of hydroelectric installation therefore can be made to simplify
Improve the maintainability of hydroelectric power generating apparatus simultaneously.
Although also, the setting place of engine section changes in rotary hub 4b and stationary hub 4a from impeller 5, but not having
It is necessary that the structure from existing hydroelectric installation specially changes the shape of impeller 5.It may be thus possible, for example, to intactly continue
Hold and possess not the contacting of impeller 5, low vibrations, low noise and the water profit of existing hydroelectric installation of the feature without oil etc.
The structure (with reference to 307a, 307b of Figure 11 and Figure 12) of plain besring.
