The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
- Fig. 3 is please referred to Fig.1, Fig. 1 is a kind of structural representation for wind turbine brake gear that the utility model embodiment provides
Figure；Fig. 2 is a kind of structural schematic diagram when not locking for wind turbine brake gear that the utility model embodiment provides；Fig. 3 is Fig. 1's
Side structure schematic view.
In a kind of specific embodiment, wind turbine brake gear provided by the utility model, including pedestal 1, on pedestal 1
Be hinged with a pair of opposing, can to the arc barriers 2 that fan shaft is clamped, what arc barriers were contacted with fan shaft
Side is equipped with brake block, is removably fixedly connected between arc barriers.
Arc barriers 2 are preferably symmetrical arranged, and pedestal 1 can be fixed on arc barriers 2 by screw rod or hinge etc.
On pedestal 1, specific articulated manner can be voluntarily configured, as long as can reach identical technique effect, to specific
Realization method be not construed as limiting.The inner wall of arc barriers is equipped with brake block, is carried out to wind turbine when it is contacted with fan shaft
Slow down, fixation can be realized by being removably fixedly connected between two arc barriers, specifically, can be by adjusting the lock of the two
Clamp force is to adjust the drag size with fan shaft.
Work as arc by the way that brake block is arranged on arc barriers 2 using wind turbine brake gear provided by the utility model
When barriers 2 close, brake block contacts with fan shaft and carries out slowing-down brake to it, without changing fan operation state, fills
It sets and is simply easy to implement.
Specifically, the upper end of arc barriers is equipped with the first mounting hole, two arc barriers are fixed through fastener.Make
Used time, fastener is each passed through two the first mounting holes, and is realized lock by locking nut respectively, by adjusting locking nut
Between spacing, adjust arc barriers and wind turbine between centers spacing, brake block contacted with fan shaft generation resistance, slow down fan shaft
Rotation, the spacing of locking nut is smaller, screw rod generate pressure it is bigger, the resistance that brake gear acts on fan shaft is got over
Greatly, until wind turbine is totally stationary, on the contrary it is smaller, when two panels arc barriers are detached from fan shaft, not to fan action.Further
Ground, fastener is specially tie down screw 3, simple in structure, is easy to implement, and certainly, in other embodiments, can also select it
The connection type of his form, as long as identical technique effect can be reached.
Further, one end that arc barriers are connect with pedestal 1 is equipped with the second mounting hole, and pedestal 1 is equipped with for pacifying
The threaded hole of loading screw.Thus it is arranged to realize being hinged for the two so that arc barriers can be rotation along straight line where screw rod
Axis is rotated, to realize the clamping to fan shaft.Alternatively, in one embodiment, arc barriers and pedestal 1 can pass through hinge
Chain, which is realized, to be hinged, and articulated manner can voluntarily be arranged according to actual needs, as long as can reach identical technique effect, to tool
The realization method of body is not construed as limiting.
In one embodiment, the inner circumferential wall of brake block arcuately barriers is uniformly arranged.Brake block arcuately obstructs
The inner circumferential wall of part is laid with, and to increase the contact area with fan shaft, ensures the frictional force between the two, further, brake block
Group number be four groups, arcuately the circumferential direction of barriers is uniformly arranged four groups of brake blocks respectively, it is preferred that brake block and arc obstruct
It is removably fixedly connected between part, with can be easy to disassemble in the serious wear of brake block.In one embodiment, brake block with
Arc barriers are fixedly connected through screw.Its is easy to disassemble, and simple in structure.
Finally, it is to be noted that, herein, relational terms such as first and second and the like be used merely to by
One entity or operation are distinguished with another entity or operation, without necessarily requiring or implying these entities or operation
Between there are any actual relationship or orders.Moreover, the terms "include", "comprise" or its any other variant meaning
