The intermeshing second bevel gear 16 of one bevel gear 15, the right side of the wind wheel disk 4 are fixedly connected there are four equally distributed solid
Fixed board 17, there are two bearing blocks 18 for the surface elasticity flexible connection of the fixed plate 17, and the top of the spill spin block 21 offers
Movable span 25, the inserted link 22 through movable span 25 and extend to outside it, two bearing blocks 18 close to one end of movable span 25
Bottom be connected respectively to one end of the spring that one is perpendicularly inserted into 17 inside shrinkage pool of fixed plate, in the shrinkage pool in fixed plate 17
It is provided with a reinforced shaft, the outer cover of the reinforced shaft is equipped with the spring, and the other end of the spring is fixedly connected on shrinkage pool
Bottom, and spill spin block 21 is located at 5 side of close push rod on two 18 intermediate blade axis 19 of bearing block；
The face wherein contacted on corner block 6 with pulley 12 is divided into two sections, and two sections of separation is located at the top above corner block
At point, when pulley 12 is located at above-mentioned separation position, one end of movable span 25 is provided on spill spin block 21 with the movement of push rod 5
And rotate and be blocked to the external margin for touching wind wheel disk 4, when pulley 12 is located at above-mentioned separation position or less, solid
Spring in 17 inside shrinkage pool of fixed board is in tension, enable usually rotation in fan blade by spring and Qi Nei reinforcement
Axis firmly in fixed plate 17 by elastic tensioning without mutual dislocation.
Two bearing blocks 18 are replaced with into yielding movable by being fixedly mounted on the surface of fixed plate 17 in the implementation which
Dynamic connection, and by reinforced shaft realize wind-force it is excessive can not by blade angle to balance when, blade 20 is carried out towards machine
The inclination storage of 1 direction of shell, break-off reach the self-shield of system.Its specific course of work is as follows:
Be in normal range of operation in wind speed, i.e., in blade 20 can be in tolerance range when, then according to first embodiment
In method, slid over below separation position on corner block 6 by pulley 12 realize wind speed matching, exist in this process
Spring in 17 inside shrinkage pool of fixed plate is in tension, enable rotation in fan blade 20 and two bearing blocks 18 of its underpart
It is enough firmly in fixed plate 17 by elastic tensioning without mutual dislocation；When wind speed is excessive, i.e., it can not pass through blade 20
The adjusting of itself Windward angle when solving, then by pulley 12 in 6 upward sliding of corner block to separation position, spill spin block at this time
One end of movable span 25 being moved to the left and rotate to the external edge for touching and abutting to wind wheel disk 4 with push rod 5 is provided on 21
Upward sliding is then proceeded to so that the rotary motion of spill spin block 21 is stopped by firm without unexpected sliding in groove on edge
Pulley 12, at this time since spill spin block 21 is blocked, then as pulley 12 rises, push rod 5 continues to be moved to the left to the left, then spill spin block
21 will force sharf 19 that two bearings is pulled to extract out of fixed plate 17, thus moved far from 17 direction of fixed plate, due to
Spill spin block 21 is located at 5 side of close push rod on two 18 intermediate blade axis 19 of bearing block, then close to push rod 5 in two bearing blocks 18
One meeting degree more separate out of fixed plate 17 than another bearing block of side is big, then leads to the leaf of two bearing blocks 18 and Qi Nei
Bobbin 19 occurs to tilt towards 1 direction of casing, then inclined also accordingly occurs simultaneously for blade 20, transports upwards to pulley 12
When moving to apex, stop motion, blade 20 reaches expected inclination storage angle at this time, the expection store angle in fixed plate
The length on deflection needed for the support strength of 17 inner springs and corner block upper critical point positional distance vertex is related.
In above process, the reinforced shaft of the outer sheathed spring in 17 concave hole of fixed plate is in normal wind ranges
It keeps bearing block 18 that can be pulled and supported by elasticity to be adjacent in fixed plate 17, guarantees the normal operation of each fan blade, it is excessive in wind-force
During executing inclination storage, the spring in 17 upper concave hole of fixed plate cooperates the reinforced shaft in it that can keep two bearing blocks
Outside extraction inclination and do not fall off.Therefore Windward angle is met using same fan blade adjustment structure in this embodiment to fit
The demand for matching and tilting two movements of storage is caused greatly reducing to need to be arranged adjusting in the prior art and store two kinds of structures
While bulky, the safety and operation ease of generating set are promoted.
Third embodiment: a kind of variable pitch and accommodation method of wind-driven generator, wherein the wind-driven generator includes level
Casing and fan blade supporting and positioning mechanism that direction is set gradually, multiple fan blades, fan blade supporting and positioning mechanism are rotatably supported at machine
Between shell and fan blade, multiple fan blades are with central symmetry distribution and elastic movable supports are in fan blade supporting and positioning mechanism, in casing
It is interior by the Lead screw transmission structure of vertical direction and the linkage of horizontally arranged corner block so that push rod is fixed in fan blade support
Level moves forward and backward on the center axis of symmetry of position mechanism and multiple fan blades, and the front end of push rod is rotated by being set in each blade
What the spill spin block on axis drove all blade Windward angles synchronizes same angulation change, during push rod level moves forward and backward, borrows
The rotary shaft for helping spill spin block to drive multiple blade bottoms is rotated forward or backwards, this is rotated and current wind speed forward or backwards
It is adapted with the back-and-forth motion direction of preset rotation speed and push rod；
Wherein the horizontal motion route of push rod is divided into adaptive and two sections of inclination storage, and two sections move forward and backward band with push rod
The end of dynamic spill spin block rotated for the first time to the external margin for touching fan blade supporting and positioning mechanism and be resisted against on the edge and by
Blocking continues to rotate to be separation, wherein multiple fan blades rely on supporting and positioning mechanism in the fan blade rotation process of adaptive section
On elastic tightening device keep by stablize support；When wind-force is more than threshold value, push rod enters inclination storage section, and push rod is more than at this time
Continue to move towards former direction after separation, since the rotation of spill spin block at this time is blocked, by spill spin block band movable vane in adaptive section
The rotary motion of piece rotary shaft be changed into spill spin block to blade rotary shaft close to the central symmetry axes side bottom with far from wind
The promotion in leaf supporting and positioning mechanism direction, under the promotion, blade rotary shaft is generated towards casing and fan blade supporting and positioning mechanism
Direction inclination and the blade rotary shaft bottom be still elastically supported near supporting and positioning mechanism without be detached from,
Until the tilt angle that makes it, the setting of the tilt angle and push rod are supported in the length and fan blade of inclination storage section
The resilient support performance of support blade is adapted on positioning mechanism.
Further, realize that fan blade is transported before and after the level of elastic support structure and push rod in fan blade supporting and positioning mechanism
Dynamic drive mechanism can be implemented are as follows: angles annular is provided with identical with fan blade quantity solid in fan blade supporting and positioning mechanism etc.
