Embodiment
In order to make the purpose of this utility model, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, bolt shield of the present utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figures 2 and 3, the bolt shield of the present embodiment comprises shield body 1 and sealing gasket 2.Wherein, shield body 1 to be located in foundation anchor bolt 3 and to have the receiving cavity holding foundation anchor bolt 3, and the bottom of shield body 1 has flanging 121.Sealing gasket 2 is pressed on the end face of tower drum flange 6, to seal receiving cavity by flanging 121.
This bolt shield to be coordinated with sealing gasket 2 by shield body 1 and forms enclosed space and prevent vapour corrosion foundation anchor bolt 3.To be installed with sealing gasket 2 by flanging 121 and to coordinate, eliminate in course of working the process offering gasket slot, manufacturing procedure is less, and processing cost is lower, and solves the problem that thin-wall part cannot offer gasket slot and then cannot use sealing gasket.In addition, only need flanging 121 be pressed on sealing gasket 2 during installation, install more quick and convenient.
In the present embodiment, the shape of shield body 1 can be bell or other shapes that can coordinate with foundation anchor bolt 3 and nut 4.Mentioned herely bellly referring to that shield body 1 is by the different cylindrical shape jointly formed as shown in Figures 2 and 3 of two diameters, but be not limited in cylindrical, also can be prism or other shapes be jointly made up of two-part of different size.
Particularly, shield body 1 comprises the first receiver portion 11 and the second receiver portion 12.First receiver portion 11 is the tubular of top seal, and its inwall is provided with the thread section 111 matched with the head of the foundation anchor bolt 3 being placed in bolt shield.Second receiver portion 12 is greater than the tubular of the cross section of the nut 4 coordinated with foundation anchor bolt 3 for cross section, its top is communicated with the first receiver portion 11 by opening, and flanging 121 is arranged on the bottom of the second receiver portion 12, coordinates for sealing gasket 2.
Be connected with foundation anchor bolt 3 by thread section 111, can ensure that screw thread protective housing is fixed solid and reliable, be convenient to screw thread protective housing simultaneously and be mounted in foundation anchor bolt 3.Like this install screw thread protective housing time without the need to additionally adding other fixed block, without tamper protection cover body 1, can prevent steam from entering better, also without the need to worrying the antirust problem of fixed block.
In other embodiments, the means of fixation of shield body 1 can also be bonding.Such as, sealing gasket 2 is pasted on flanging 121, then shield body 1 and sealing gasket 2 are together pasted on tower drum flange 6.
Preferably, the thin-wall part that bolt shield is formed in one, makes bolt shield be more convenient for processing like this, also easily ensures machining accuracy.
Certainly, in other embodiments, each several part of bolt shield assembles after can processing respectively.Such as, first receiver portion 11 is fixedly installed nut as thread section 111, also can the first receiver portion 11, second receiver portion 12 and flanging 121 one-body molded after on the first receiver portion 11, processing thread section 111 by mach mode.
When installing this bolt shield, as shown in Figures 2 and 3, shield body 1 is located on foundation anchor bolt 3 and nut 4, the first receiver portion 11 is made to hold the head of foundation anchor bolt 3 and make the second receiver portion 12 hold nut 4, and screwing act on sealing gasket 2 is clamped by the flanging 121 of the second receiver portion 12 and tower drum flange 6 jointly by thread section 111 and foundation anchor bolt 3 head threads, thus the head of foundation anchor bolt 3 and nut 4 are sealed in the inside of shield body 1.Abut sealing gasket 2 by the flanging 121 of the second receiver portion 12, make sealing effect obtain sufficient guarantee, can also avoid damaging sealing gasket 2 simultaneously, touch outside rainwater to prevent the head of foundation anchor bolt 3 and nut 4 or moisture causes corrosion.
Particularly, the material of sealing gasket 2 can adopt silica gel or rubber etc. to have the material of elastic performance, to reach good sealing effect.Shield body 1 can adopt lower-cost plastics injection moulding to make, and more conveniently like this carries out injection molding, and processing cost is lower, and work efficiency is higher, reduces fabricating cost.
As one preferred embodiment, as shown in Figures 2 and 3, the cross section of the second receiver portion 12, flanging 121 and sealing gasket 2 are ring, and the outer circumferential face of flanging 121 radially protrudes from the outer circumferential face of sealing gasket 2, and also namely the external diameter of sealing gasket 2 is less than the external diameter of flanging 121.Like this, the outer annular edge of sealing gasket 2 is pressed within the annular of flanging 121 completely, avoids the phenomenon occurring the outer annular edge of sealing gasket 2 is rolled up, advantageously in sealing, and contribute to the working life of improving sealing gasket 2.
Wherein, the internal diameter of sealing gasket 2 is greater than nut 4 external diameter.In actual use, nut 4 can directly overlay on tower drum flange 6 by the effect that screws between foundation anchor bolt 3, also can overlay at tower drum flange 6 by plain cushion 5, and it is outside that sealing gasket 2 can be enclosed within nut 4.
As shown in Figures 2 and 3, usual foundation anchor bolt 3 is set with the plain cushion 5 coordinated with nut 4, and plain cushion 5 can be high strength pad, to improve connection reliability and working life.Plain cushion 5 is fixed between nut 4 and tower drum flange 6 by the effect that screws of nut 4 and foundation anchor bolt 3, and the cross section of the second receiver portion 12 is greater than the cross section of plain cushion 5, makes the second receiver portion 12 hold nut 4 and plain cushion 5 simultaneously.At this moment, the internal diameter of sealing gasket 2 is greater than the external diameter of plain cushion 5, makes sealing gasket 2 can be enclosed within the outside of nut 4 and plain cushion 5.
According to another aspect of the present utility model, provide a kind of wind power generating set, it comprises tower cylinder, foundation anchor bolt 3 and bolt shield, and bolt shield is above-mentioned bolt shield.Adopt this bolt shield can protect foundation anchor bolt 3 in the presence of a harsh environment, prevent rust corrosion, improve device security.
The bolt shield tool of above embodiment has the following advantages:
Be provided with the thread section matched with the head of the foundation anchor bolt being placed in protective housing at the inwall of the first receiver portion, shield body be connected with foundation anchor bolt convenient, and without the need to additionally adding fixed block.
In the bottom of the second receiver portion, flanging is set, flanging is equipped with the sealing gasket of annular, make bolt shield can prevent outside rainwater or moisture from causing corrosion to foundation anchor bolt, nut and plain cushion, and this body structure of bolt shield is simple, with low cost, easy to use.
The above embodiment only have expressed several mode of execution of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.Therefore, the protection domain of the utility model patent should be as the criterion with claims.
