Abstract
The utility model discloses a tail vane yawing device which comprises a motor and is characterized by further comprising a sealed housing for protecting the motor, a base connection piece for connecting the housing with a tail vane base, and a tail cover arranged at one end of the housing, wherein the tail cover is connected with a tail vane rod and is made of a flexible material. The tail vane yawing device has the benefits that the tail vane yawing device adopts the sealed tail cover made of the flexible material to prevent rain, wind and dust, so that the yawing device can be comprehensively, reliably and effectively protected, meanwhile, the tail vane rod can freely yaw and return due to application of the flexible material.
Description
Technical field
The utility model relates to a kind of tail vane yaw device.
Background technique
The tail vane yaw device is widely used in the wind-driven generator of going off course with tail vane, as shown in Figure 1, and usually by motor, tail vane bar, tail plate, tail vane pedestal, the compositions such as hood.Existing hood normally hard glass steel or metal manufacturing forms, and shape mostly is hemisphere, taper or bullet-headed etc., and as shown in Figures 2 and 3, at the side fluting of hood near the tail vane bar, freely goes off course and return to guarantee the tail vane bar.But; such structure can not play a good protection to yaw device; can cause accumulated snow or accumulated ice, can pile up sandy soil in the large area of dust storm at the low temperature sleety weather, affect the normal operation of tail vane yaw device, even might cause the damage of wind-driven generator.At present, also do not have a kind of hood, the effect that can play the protection yaw device can guarantee again freely going off course and return of tail vane bar.
The model utility content
Be to solve the deficiencies in the prior art, the purpose of this utility model is to provide a kind of hood yaw device, can guarantee that not only the tail vane bar freely goes off course and return, can also protect effectively reliably yaw device.
In order to realize above-mentioned target, the utility model adopts following technological scheme:
The tail vane yaw device is characterized in that, comprises motor; the housing with the protection said motor of sealing for the pedestal link that housing is connected with the tail vane pedestal, is arranged at the hood of above-mentioned housing one end; above-mentioned hood is connected with the tail vane bar, and above-mentioned hood is made by flexible material.
Aforesaid tail vane yaw device is characterized in that, above-mentioned hood is the sealing configuration of solid of rotation.
Aforesaid tail vane yaw device is characterized in that, above-mentioned hood diameter in axial direction is different, near the diameter of the above-mentioned housing one end diameter greater than an end that is connected with the tail vane bar.
Aforesaid tail vane yaw device is characterized in that above-mentioned hood and housing are one-body molded.
Aforesaid tail vane yaw device is characterized in that above-mentioned hood separates moulding with housing, and both adopt screw to be fixedly connected with.
Aforesaid tail vane yaw device is characterized in that, above-mentioned hood and tail vane bar are one-body molded.
Aforesaid tail vane yaw device is characterized in that, above-mentioned hood separates moulding with the tail vane bar, and both adopt screw to be fixedly connected with.
Aforesaid tail vane yaw device is characterized in that, above-mentioned flexible material is rubber, plastics or metallic hose.
Usefulness of the present utility model is: tail vane yaw device of the present utility model; the sealing hood that has adopted flexible material to make; windproof and rain proof and dustproof can be protected yaw device comprehensively, reliably, effectively, and flexible material can make the tail vane bar freely go off course and return simultaneously.
Description of drawings
Fig. 1 is the structural representation of existing tail vane yaw device;
Fig. 2 is the structural representation of existing hood;
Fig. 3 is another angle structural representation of existing hood;
Fig. 4 is the structural representation of a preferred embodiment of tail vane yaw device of the present utility model.
The implication of reference character among the figure:
1, housing, 2, the tail vane pedestal, 3, the pedestal link, 4, hood, 5, the tail vane bar.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done concrete introduction.
Referring to Fig. 4, tail vane yaw device of the present utility model comprises motor (being positioned at housing 1 inside, invisible); sealing is with the housing 1 of protection said motor; for the pedestal link 3 that housing 1 is connected with tail vane pedestal 2, be arranged at the hood 4 of housing 1 one ends, and hood 4 is connected with tail vane bar 5.
In order to realize freely going off course and return, hood 4 is made by flexible material.Preferred flexible material is rubber, plastics or metallic hose.
In the utility model, hood 4 is preferably the sealing configuration of solid of rotation, can realize freely going off course and return in protect better hood 4 yaw devices.
In order to improve the flexibility ratio in when driftage, hood 4 is different along the diameter of its axial direction, near the diameter of the housing 1 one ends diameter greater than an end that is connected with tail vane bar 5.
As a kind of scheme, hood 4 is one-body molded with housing 1.As another kind of scheme, hood 4 separates moulding with housing 1, and both adopt screw to be fixedly connected with.
Same as above, hood 4 can be one-body molded with tail vane bar 5; Also can separate moulding, both adopt screw to be fixedly connected with.
More than show and described basic principle of the present utility model, major character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technological scheme that the mode of equivalent transformation obtains, all drops in the protection domain of the present utility model.
