Embodiment
Technological means, creation characteristic, reached purpose and effect to realize the utility model are easy to understand, below
With reference to embodiment, the utility model is expanded on further.
In this application, term " first ", " second " are only used for describing purpose, and it is not intended that instruction or hint are relative
Importance or the implicit quantity for indicating indicated technical characteristic.In the description of the invention, " at least one piece " is meant that
More than one piece, unless otherwise specifically defined.
In this application, unless otherwise clearly defined and limited, the term such as term " connection ", " fixation " should do broad sense reason
Solution, for example, it may be fixedly connected or be detachably connected, or integrally；Can be mechanical connection or electricity
Connection；Can be joined directly together, can also be indirectly connected by intermediary, can be two element internals connection or two
The interaction relationship of element.For the ordinary skill in the art, above-mentioned term can be understood as the case may be
Concrete meaning in the present invention.
As shown in figure 1, the stator stopping device of wind-power slip ring includes the support 3 and one that one end is fixedly connected with gear-box 2
The stopper arms 4 being fixedly connected with wind-power slip ring are held, because the stator of wind-power slip ring 1 will penetrate cable, therefore preferably by stopper arms 4
It is arranged on the upper end of wind-power slip ring.The other end of the support 3 is fixed with a dogbolt 5, and the other end of the stopper arms 4 is opened
There is an open slot 41, preferably open slot 41 is U-lag, and the threaded shank of the dogbolt 5 passes through the open slot 41, described to open
The width of mouth groove 41 is more than the diameter of the threaded shank of the dogbolt 5.In the present embodiment, due to dogbolt 5 and stop
Arm 4 is without direct annexation, and dogbolt 5 can only prevent the twisting of the stator of wind-power slip ring 1, without to wind-power slip ring
1 applies added force radially, therefore vibration on gear-box 2 and deformation of support 3 etc. are all without causing slip ring
Skew radially, so as to ensure that slip ring is run well.
In one embodiment, the support 3 include half cylinder 31, be arranged on the both ends of half cylinder 31 into semi-circular
The first connecting plate 32 and the second connecting plate 33, the connecting plate 33 of the first connecting plate 32 and second is respectively used to and gear-box 2
Connected with dogbolt 5.It is preferred that half cylinder 31 is columnar structured and angle circumferentially is between 190~210 °, phase
Ying Di, the first connecting plate 32 and the second connecting plate 33 are then into semi-circular shape.Due to half cylinder 31, therefore the branch of said structure
Frame 3 has the advantages of being easy to dismounting and torsional strength high.
One kind as such scheme is improved, and the width of second connecting plate 33 is more than the width of the first connecting plate 32,
I.e. long along the connecting plate 32 of the second connecting plate in the radial direction 33 to the first of half cylinder 31, it is since it is considered that only so to set
Swing arm 4 has certain length, it is therefore necessary to sets more wider by the second connecting plate 33, so as to which dogbolt 5 is installed
Above.
Another kind as such scheme improves, the support 3 is also arranged on half cylinder 31 including at least one piece,
And the first stiffener 34 between the connecting plate 33 of the first connecting plate 32 and second, the block number of the first stiffener 34 according to
Depending on the length of half cylinder 31.The first stiffener 34 is set to strengthen the rigidity of support 3.Preferably, half cylinder 31
Both sides are respectively equipped with second stiffener 35 for running through its length direction, first connecting plate 32, the second connecting plate 33 and the
One end of one stiffener 34 is connected with second stiffener 35 respectively.The second stiffener 35 is set to further enhance branch
The rigidity of frame 3.
As the further improvement of such scheme, as shown in Fig. 2 the both sides cell wall of the open slot 41 is embedded with one respectively
First magnetic patch 42, the both sides of the threaded shank of the dogbolt 5 are embedded with one second magnetic patch 51, the first magnetic patch 42 and second respectively
All in the same plane, every piece of second magnetic patch 51 and one piece of first magnetic patch 42 are oppositely arranged and keep mutually exclusive magnetic patch 51
State.Second magnetic patch 51 corresponding to two pairs produces repulsive force to two piece of first magnetic patch 42 respectively, so that dogbolt 5 is very
Hardly possible touches with stopper arms 4, therefore can further eliminate the additional radial power for acting on slip ring so that slip ring is better
Operation.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above, for
