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.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding And modification, the scope of the present invention is defined by the appended.
