Cylindricality guide face and electrification component, the bore of the cylinder guide face are adapted with runner size.
As shown in fig. 7, electrification component 109 is placed in inside pipeline, sustainable electrification component 109 is further included relative to fixing axle
The swing mechanism of 111 axis direction vertical oscillations；Fixing axle 111 is fixed on a support base, in the present embodiment support base with
Pressure reducing valve casing is fixedly connected；The direction that fixing axle 111 is set is when can make the electrification component 109 swing to extreme lower position and fluid
Flow direction is vertical.
Swing mechanism includes the swing rod 110 that one end is sheathed in fixing axle 111, the other end is fixedly connected with generating set,
And the return spring 112 of the swing position of generating set is limited, the return spring 112 is connected in fixing axle 111.
Fluid in pipeline passes through before 9 valve of pressure reducing valve 113 water conservancy diversion of diversion seat being equipped with, and flows through electrification component 109.Work as fluid
Flow velocity is excessive, when fluid is more than the screen resilience of return spring 112 to the active force of the blade of generating set, fluid forces power generation
Component 109 is rotated with swing rod 110 along fixing axle 111, and runner 102 is formed radially inclination angle with pipeline, and segment fluid flow is from runner with subtracting
Gap between pressure valve housing 114 is flowed through, and the fluid for flowing through runner 102 is accordingly reduced, and flows through the fluid of runner bucket
Thrust change to the angle of blade so that vane stress is corresponding reduces, further reduce the rotating speed of blade.Electrification component
109 electric currents produced are not mutated because of the increase of fluid flow rate.
When fluid flow rate diminishes, and fluid is less than the screen resilience of return spring 112 to the active force of the blade of runner, power generation
Component 109 rotates along fixing axle 111 with swing rod 110 by the screen resilience of return spring 112, vertical position is returned to from incident angle
Put.As electrification component 109 and the gap of pressure reducing valve casing 114 are gradually reduced, the number of dropouts of fluid therefrom is reduced, correspondingly,
Flow through runner bucket fluid become it is more, and flow through send out runner bucket the thrust of fluid and the angle of blade changes so that leaf
Piece stress accordingly increases, and further increases the rotating speed of blade.Electrification component 109 produce electric current not because of the reduction of fluid flow rate and
Mutation.
The electric current that final electrification component 109 produces is not mutated because of the mutation of fluid flow rate, so as to fulfill stabling current
