In sum, the bolt corrosion protective device for electric power tower of the present utility model, by the cavity design in protection valve jacket, achieves bolt corrosion protective device and wraps up bolt and the nut being fastened on bolt periphery and isolate; By protection valve jacket plastic protective cover and anti-corrosion belt Rotating fields; corrosion protection belt and outside air generation chemical reaction can be made; plastic protective cover is formed the epithelium that one deck has good ageing-resistant performance; because the epithelium formed has good isolated moisture and the function of air; and there is good ageing resistance; therefore, make this device need the object of corrosion protection to have obvious corrosion protection effect to the fastening pieces such as screw bolt and nut or other, and effective acting time is permanent.Therefore, there is structure simply, be not subject to such environmental effects, easily operate, there is the advantages such as good anti-corrosion performance, long service life.
Accompanying drawing explanation
Fig. 1 is the structure sectional view of a kind of bolt corrosion protective device for electric power tower of the present utility model;
Using state figure when Fig. 2 is bolt corrosion protective device of the present utility model parcel screw bolt and nut.
Embodiment
Embodiment 1
As depicted in figs. 1 and 2; a kind of bolt corrosion protective device for electric power tower described by the present embodiment 1; comprise protection valve jacket 1, be provided with the cavity 11 of parcel bolt 3 and nut 4 in described protecting sheathing, protecting sheathing is made up of the plastic protective cover 121 overlapped and corrosion protection belt 122.
By the cavity design in protection valve jacket, achieve bolt corrosion protective device and bolt and the nut being fastened on bolt periphery are wrapped up and isolated; By protection valve jacket plastic protective cover and anti-corrosion belt Rotating fields; corrosion protection belt and outside air generation chemical reaction can be made; plastic protective cover is formed the epithelium that one deck has good ageing-resistant performance; because the epithelium formed has good isolated moisture and the function of air; and there is good ageing resistance; therefore, make this device need the object of corrosion protection to have obvious corrosion protection effect to the fastening pieces such as screw bolt and nut or other, and effective acting time is permanent.Therefore the structure of this bolt corrosion protective device simply, is not subject to such environmental effects, easily operates, has good anti-corrosion performance, long service life.
Further, described corrosion protection belt covers the periphery being arranged on plastic protective cover, and cavity is located in plastic protective cover; Namely protect valve jacket from being made up of plastic protective cover and corrosion protection belt successively toward outside inside it.Corrosion protection belt covers the periphery being arranged on plastic protective cover; be conducive to corrosion protection belt to contact with outside air more in large area; and react with air, formed in plastic protective cover periphery and there is good isolated moisture and the epithelium of air function, directly play corrosion protection effect.In the present embodiment, corrosion protection belt is identical with the structure and material of existing anti-corrosion belt.
In order to make this device to be stably fastened on bolt, and wrap up the fastening pieces such as screw bolt and nut better.Further, described cavity is made up of with the nut cavity 112 for wrapping up the nut be connected with bolton the bolt cavity 111 for wrapping up bolt; Described bolt cavity inner wall is provided with the screw thread coordinated with bolt; Described nut cavity is arranged on the below of described bolt cavity, and is communicated with bolt cavity, and the axis of nut cavity and the axis of bolt cavity are located along the same line, and nut cavity runs through the bottom surface of protection valve jacket.By bolt cavity and the nut cavity of connection; achieve bolt and the common parcel of nut being fastened on bolt periphery; and achieve this device and be fastened on by bolt cavity and need on protected bolt; corrosion protection is carried out to screw bolt and nut, and improves the stability of this device installation and the applicability of use.Because nut is the periphery being fastened on bolt, therefore, the internal diameter of nut cavity is larger than the internal diameter of bolt cavity.
Further, the structure of the protection valve jacket outer wall of corresponding bolt cavity is frustoconic shape, and the structure of the protection valve jacket outer wall of corresponding nut cavity is cylindrical.The outer wall of the protection valve jacket formed by the combination in frustoconic shape outer wall and cylindrical outer wall face, is convenient to corrosion protection belt and plastic protective cover are closely fitted.
As depicted in figs. 1 and 2, the bolt cavity in protection valve jacket is positioned at above nut cavity, and bolt cavity does not run through the end face of protection valve jacket, and nut cavity runs through the bottom surface of protection valve jacket, and therefore, protection valve jacket only has one to be positioned at its bottom surface and leads to extraneous outlet.When using this device, first, the nut cavity of protection valve jacket being aimed at bolt, then protection valve jacket being entangled bolt and being fastened on two nuts on bolt, making nut cavity and bolt cavity jointly wrap two nuts; Then; apply a rotating force in protection valve jacket; screw thread in bolt cavity is threaded by screwing with bolt; to realize bolt China and foreign countries, to be exposed at nut outer and establish threaded one end completely and bolt cavity compact siro spinning technology, thus achieve protection valve jacket of the present utility model to the tight seal of screw bolt and nut.In addition, before protection valve jacket seals screw bolt and nut, first can coat anti-corrosion plaster 5 on the surface of screw bolt and nut, also can not coat anti-corrosion plaster on the surface of screw bolt and nut.Because the corrosion protection belt in protection valve jacket and outside air generation chemical reaction, plastic protective cover is formed one deck epithelium, and this epithelium has good isolated moisture and the function of air, and has good ageing resistance.
In addition; the utility model also has other variant embodiment; such as: the setting position changing plastic protective cover and corrosion protection belt; that is: described plastic protective cover covers that to be arranged on described corrosion protection belt peripheral, is namely protection valve jacket from being made up of corrosion protection belt and plastic protective cover successively toward outside inside it.
The above is only preferred embodiment of the present utility model, not does any pro forma restriction to structure of the present utility model.Every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all still belong in the scope of the technical solution of the utility model.
