Abstract
The utility model discloses a kind of antirust screw nut with rubber o-ring, comprise anti-rust cap main body (1), described anti-rust cap main body (1) is located at ground bolt (3), nut (4) outward, described anti-rust cap main body (1) is provided with groove (6), it is characterized in that: be provided with internal thread (7) in described anti-rust cap main body (1), described internal thread (7) matches with ground bolt (3) screw thread; Described groove (6) is combined with O RunddichtringO (2).The utility model difficult drop-off.Realize the effect of effective sealing, stop outside rainwater, moisture enters anti-rust cap inside, significantly reduces the probability of ground bolt and nut generation corrosion, have rust-proof effect better, more lasting technique effect.
Description
Technical field
The utility model relates to a kind of Rustproofing apparatus of wind power generating set ground bolt, particularly relates to a kind of antirust screw nut with rubber o-ring.
Background technique
Large-scale Wind Turbines is connected with ground by the ground bolt be embedded in ground, then locks with nut.Nuts and bolt head is outside exposed, and outside rainwater, moisture easily cause the corrosion of bolt, nut.CN202194927U discloses a kind of anti-rust cap of fixed tower cylinder, but this anti-rust cap is directly fastened on outside screw bolt and nut next antirust by anti-rust cap rubber, and the shortcoming of this structure is: 1. the anti-rust cap be directly fastened on outside screw bolt and nut easily comes off and loses sealing effect; 2. the annular recess technological scheme on the anti-rust cap annular the brim of a hat is unreasonable imperfect, and groove itself does not reach the object of sealing, makes rainwater on the contrary, moisture accumulation causes bolt corrosion at groove.
Model utility content
Technical problem to be solved in the utility model is to provide a kind of Rustproofing apparatus of wind power generating set ground bolt, a kind of antirust screw nut with rubber o-ring is especially provided, overcome that above-mentioned anti-rust cap easily comes off, technological scheme defectiveness problem, the utility model is applied on Large-scale Wind Turbines ground bolt, can effectively prevent bolt and nut from producing corrosion.
Technical problem to be solved in the utility model is achieved through the following technical solutions:
With an antirust screw nut for rubber o-ring, comprise anti-rust cap main body, described anti-rust cap main body is located at outside ground bolt, nut, and described anti-rust cap main body is provided with groove; Be provided with internal thread in described anti-rust cap main body, described internal thread matches with the screw thread of ground bolt head, is tightened in ground bolt head by screw thread anti-rust cap main body; Described groove fit has an O type circle; Described O type circle adopts rubber, plastics or other known sealing material to make, described anti-rust cap main body is screwed on bolt can compress bottom O type circle, O type circle is made to produce extrusion-deformation, effectively can realize sealing, rainwater, the moisture of prevention outside enter anti-rust cap inside, reduce the probability of ground bolt, nut generation corrosion.
Described groove is bottom annular groove, and its degree of depth is less than the cross-sectional diameter of O type circle, is beneficial to squeezing effect effectively.
Described anti-rust cap main body can be set to the bell or known shape that can coordinate.
The utility model adopts technique scheme to have following beneficial effect:
1. the utility model main body makes anti-rust cap main body be screwed on bolt by internal thread, difficult drop-off.
2., simultaneously by O type circle, described anti-rust cap main body compresses bottom O type circle downwards, makes O type circle produce distortion, and realize the effect of effective sealing, stop outside rainwater, moisture enters anti-rust cap inside.
3. be bolted on column foot flange due to described, downward power is produced when described antirust screw nut is tightened, make described antirust screw nut be fixed on the outside of described bolt above column foot flange more closely, significantly reduce the probability of ground bolt and nut generation corrosion further.
4. compared to the prior art there is rust-proof effect better more lasting with documents.

Embodiment
An antirust screw nut as shown in Figure 1, Figure 2, Figure 3 shows with rubber o-ring, anti-rust cap main body 1 is fixed on ground bolt 3 and nut 4 by its interior threaded hole 7.O type circle 2 is placed in the groove 6 of anti-rust cap main body 1.Described groove 6 is bottom annular groove, and its degree of depth is less than the cross-sectional diameter of O type circle 2.By screwing anti-rust cap main body 1, due to coordinating of interior threaded hole 7 and ground bolt 3, anti-rust cap main body 1 moves down compressing O type circle 2, O type circle 2 is produced be out of shape and compress column foot flange 5 to be formed and seal, make outside rainwater, moisture is difficult to pass through, prevent ground bolt 3 and nut 4 from corrosion occurring.
Claims (4)
1. the antirust screw nut with rubber o-ring, comprise anti-rust cap main body (1), described anti-rust cap main body (1) is located at ground bolt (3), nut (4) outward, described anti-rust cap main body (1) is provided with groove (6), it is characterized in that: be provided with internal thread (7) in described anti-rust cap main body (1), described internal thread (7) matches with the screw thread of ground bolt (3) head; Described groove (6) is combined with an O type circle (2).
2. the antirust screw nut of band rubber o-ring according to claim 1, is characterized in that: the degree of depth of described groove (6) is less than the cross-sectional diameter of O type circle (2).
3. the antirust screw nut of band rubber o-ring according to claim 1 and 2, is characterized in that: described O type circle is the seal ring of rubber, plastics or other known sealing material.
4. the antirust screw nut of band rubber o-ring according to claim 3, is characterized in that: described anti-rust cap main body (1) is the bell or known shape that can coordinate.
