Abstract
A wind wheel hub of a wind turbine generator system belongs to the technical field of wind turbine generator systems, and is connected with a generator. A hub security device is fixed in the wind wheel hub; one end of the hub security device is connected with the generator; the hub security device comprises a connecting plate and a cat ladder; the cat ladder is a framework-type structure; one end of the cat ladder is connected with the generator through the connecting plate; and the pedals of the cat ladder have patterns. Through the adoption of the structure, safety problem of working personnel during emergency operation accidents can be properly solved, for example, when the hub rotates suddenly, the working personnel can hold the cat ladder which is connected with the generator and fixed in position, so that the working personnel on the cat ladder can rotate with the hub regularly. Therefore, the safety of the working personnel is greatly reduced; the structure is simple; the realization is easy; and the investment cost is low.
Description
Technical field
The utility model belongs to the wind-driven generator technical group field, particularly relates to a kind of wind wheel wheel hub that is used for wind power generating set.
Background technique
See that on the whole wind power generating set can be divided into wind wheel, cabin, pylon and basic several sections.Wherein wind wheel is made up of blade and wheel hub.Wheel hub is that blade and vane group are fixed on the device in the rotating shaft, it with the power of wind wheel and transmission of torque in the main transmission machine.In the maintenance to wind power generating set, the inner maintenance of wheel hub has very important significance, in view of the attendant will get into operation in the wheel hub; Though during operation, wind wheel stops in the staff gets into wheel hub, if burst accident occurs; After the staff got into, wheel hub rotated suddenly, and the staff will follow the rotation of wheel hub and rotate; Because of being connected to a lot of circuits in the wheel hub, in rotary course, the staff is prone to be snarled and then life safety is difficult to ensure by circuit.Therefore developing a kind of wheel hub safety installations becomes a top priority to guarantee personal safety.
The model utility content
To the technical problem of above-mentioned existence, the utility model provides a kind of wind power generating set, and it has the wheel hub safety installations, and it is support personnel's safety greatly.
The utility model is realized through following technological scheme:
A kind of wind wheel wheel hub that is used for wind power generating set is connected with generator, comprises hub body and wheel hub safety installations, in said wind wheel wheel hub, is fixed with the wheel hub safety installations with the generator connecting end, and said wheel hub safety installations one end is connected with generator.
Said wheel hub safety installations comprises connecting plate and cat ladder, and said cat ladder is a tower structure, and cat ladder one end is connected with generator through connecting plate, and ladder rung is the decorative pattern pedal.
The beneficial effect of the utility model is:
Adopt the structure of the utility model, the safety problem of solution staff that can be appropriate when the operation burst is unexpected is as when wheel hub rotates suddenly; The staff can catch cat ladder, because of cat ladder is connected with generator, and fixed-site; The staff can greatly reduce staff's danger along with wheel hub clocklike rotates above that, and this is simple in structure; Be prone to realize that the input expense is little.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the wheel hub safety installations structural representation among Fig. 1.
Fig. 3 is the left view of Fig. 2.
Fig. 4 is the plan view of Fig. 2.
Among the figure: 1. generator, 2. connecting plate, 3. cat ladder handrail, 4. pedal, 5. cat ladder, 6. wheel hub.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed description.
Embodiment: as shown in Figure 1, a kind of wind wheel wheel hub that is used for wind power generating set of the utility model is connected with generator 1, at said wind wheel wheel hub 6 internal fixation the wheel hub safety installations is arranged, and said wheel hub 6 safety installationss one end is connected with generator 1.
Like Fig. 2-shown in Figure 4, said wheel hub safety installations comprises connecting plate 2 and cat ladder 5, and said cat ladder 5 be a tower structure, and cat ladder 5 one ends pass through connecting plate 2 and are connected with generator 1, and ladder rung 4 is the decorative pattern pedal.
The working procedure of the utility model:
When the staff when generator 1 gets into wheel hub 6, at first get into pedal 4, again and then get into innerly, being set to of cat ladder 5 structures makes things convenient for the staff when escape, to use.As: when wheel hub 6 rotates suddenly; The staff can catch cat ladder 5 easily; Because cat ladder 5 is connected with the generator bolt through connecting plate, so after the staff catches cat ladder 5, above that can be along with wheel hub 6 clocklike rotates; The Security that is the staff has obtained guarantee, has reduced staff's danger.
