Abstract
The utility model relates to a dual static sealing device for a fuse cutout. The fuse cutout comprises an installation pedestal and a handle which is arranged at the end face of the installation pedestal, the handle comprises a cover plate, the cover plate and the handle are formed in an integrated manner, and the cover plate is arranged at the end face of the installation pedestal; the sealing device comprises a cap cover which is firmly connected with the installation pedestal by a thread, and further comprises an end-face sealing ring and a radial sealing ring; the end-face sealing ring is arranged between the end face of the installation pedestal and the cover plate, and the radial sealing ring is arranged between the side face of the installation pedestal and the cap cover. Compared with a single sealing device, the dual static sealing device has the function of dual sealing and protecting, can still effectively carry out sealing when the single sealing device is in failed state, and prolongs the effective sealing time; when a cap needs to be opened for replacing a fusing piece, the dual static sealing device can prevent water drops from entering the inner part of the fuse cutout and ensure the insulating safety performance of the fuse cutout.
Description
Technical field
The utility model relates to a kind of double static sealing device that is used for fuse.
Background technology
Buried case becomes, wind power generation box becomes owing to be installed on bleak and desolate windy and dusty and humid regions such as desert, Gobi desert, coastal waters, nearly river, the fuse that is adopted needs effectively, sealing reliably, to prevent intrusions such as extraneous air, dust, water, guarantee fuse insulation safety performance.And the sealing device of general fuse adopts the fastening cap of threaded rotation to carry out single sealing with sealing ring by directly contacting mostly, because the turning effort of cap in the fastening process of compression, it is stressed easily to drive the sealing ring rotation, cause that the sealing ring local pressure stretches and compression, cause the sealing ring compression inhomogeneous, seal failure causes fuse potential safety hazard to occur easily.
Summary of the invention
The purpose of this utility model provides a kind of double static sealing device that is used for fuse exactly in order to address the above problem, the sealing device adopts radially, end face double static sealing mode, has guaranteed fuse insulation safety performance.
The purpose of this utility model is achieved in that the utility model provides a kind of double static sealing device that is used for fuse, this fuse comprises mounting base and is located at the handle of mounting base end face, described handle comprises integrated with it cover plate, described cover plate is located at the end face of mounting base, described sealing device comprises the cap that is connected by screw threads for fastening with described mounting base, and described sealing device comprises that also the end-face seal ring of being located between mounting base end face and the cover plate and is located at the radial direction seal ring between mounting base side and the cap.
At the above-mentioned double static sealing device that is used for fuse, the mounting base end face is provided with annular groove, and described end-face seal ring places respectively in the described annular groove.
At the above-mentioned double static sealing device that is used for fuse, the mounting base side is provided with annular groove near the screw thread place, and described radial direction seal ring places in the described annular groove.
At the above-mentioned double static sealing device that is used for fuse, sealing ring adopts the organic rubber composite material.
At the above-mentioned double static sealing device that is used for fuse, cap is equipped with the gear-like profile.
The utility model is compared with general fuse sealing device, has following characteristics:
1. have radially, end face dual-seal protection;
2. under the single sealing mechanism failure state, still can effectively seal;
3. prolong effective sealing time;
4. when need are opened cap replacing fuse member, prevent that the globule from entering fuse inside, guarantee fuse insulation safety performance.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Referring to Fig. 1, fuse comprises mounting base 5 and is located at the handle 22 of mounting base 5 end faces, this handle 22 also comprises integrated with it cover plate 21, this cover plate 21 is placed on mounting base 5 end faces, the utility model sealing device is installed on the mounting base 5 of fuse, comprise cap 1, end-face seal ring 31 and radial direction seal ring 32, wherein, end-face seal ring 31 fills up between mounting base 5 and cover plate 21, mounting base 5 end faces and end-face seal ring 31 contact positions, be equipped with annular recessed poor 41, this annular groove 41 has the sealing ring location and increases sealing contact surface, thereby improve the effect of sealing validity, end-face seal ring 31 places in this annular groove 41, and contact static seal with cover plate 21 end faces, described cap 1 is placed on described handle 22 and the cover plate 21, be fastenedly connected by the screw thread on the mounting base 56, screw threads for fastening power puts on end-face seal ring 31 by mounting base 5 and cover plate 21, it is compressed, make end-face seal ring 31 and mounting base 5, the tight contact of cover plate end face, reach inside and outside isolating seal effect, binding thread 6 end places between cap 1 and the fuse mounting base 5 also are provided with radial direction seal ring 32, mounting base 5 has a circle circular groove 42 in the relevant position, be used to hold radial direction seal ring 32, radial direction seal ring 32 is with the mounting base end face, screw thread is effectively isolated with extraneous, guaranteed mounting base port drying, prevent that effectively the globule from entering fuse inside, guaranteed security of products.The utility model sealing device is compared with single sealing mechanism, has the dual-seal protection; Under the single sealing mechanism failure state, still can effectively seal; Prolong effective sealing time; When need are opened cap replacing fuse member, prevent that the globule from entering fuse inside, guarantee fuse insulation safety performance.
At the above-mentioned double static sealing device that is used for fuse, cap 1 is equipped with the supplier and just rotates and supply the fastening gear-like profile 7 of round nut wrench, and that described end-face seal ring 31 and radial direction seal ring 32 adopt is high temperature resistant, oil resistant, ageing-resistant, elastomeric organic rubber composite material are made.
Above embodiment is only for the usefulness that the utility model is described, but not to restriction of the present utility model, person skilled in the relevant technique, under the situation that does not break away from spirit and scope of the present utility model, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present utility model, should be limited by each claim.
