The technical scheme of the utility model is that: the end part sealing structure of the insulating protective sleeve comprises at least two sealing rings, the sealing rings are detachably arranged on the inner wall of the end part of the insulating protective sleeve shell, and a warning device is arranged on the outer wall of the insulating protective sleeve shell between the sealing rings;
warning device includes the shell, meets water inflation thing and meets water color changing thing, the shell is transparent, shell one side tip is equipped with a plurality of through-holes, realizes and the inside intercommunication of insulating lag casing, inside from inside to outside being equipped with in proper order meets water inflation thing and meets water color changing thing of shell.
Preferably, the warning device is detachably arranged on the outer wall of the shell of the insulating protective sleeve.
Preferably, the shell of the warning device is in threaded connection or clamped connection with the insulating protective sleeve shell.
Preferably, the inner wall of the end part of the insulating protective sleeve shell is provided with a mounting groove, and the sealing ring is arranged in the mounting groove.
Preferably, the sealing ring is any one of an ethylene propylene diene monomer sealing ring, a silicone rubber sealing ring or a polyurethane sealing ring.
Preferably, the water-swellable substance is water-blocking yarn or water-swellable resin particles.
Preferably, the water-color-changing substance is water-color-developing test paper or anhydrous copper sulfate particles.
Preferably, a layer of water-soluble film is arranged between the water-swelling material and the inner wall of the shell.
The utility model has the advantages that: be equipped with warning device at two sealing washers, outside sealing washer is ageing and then lose the leakproofness easily more, after steam passed first layer sealing washer, can be absorbed by meeting water inflation thing, meets water inflation thing on one side inwards expand, prevents that steam from further invading, and the another side fuses with meeting water color change thing, makes and meets water color change thing and discolours for the staff can discover through transparent shell in daily patrolling and examining.
The utility model provides an end sealing structure of insulating lag not only has the secondary function of blocking water, still has the warning function, and the easy access personnel in time discover and handle the sealing washer inefficacy problem to the even running of effectual maintenance electric wire netting.

Detailed Description
The technical solution of the present invention will be described clearly and completely with reference to the accompanying drawings, and obviously, the described embodiments are some, but not all embodiments of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "front", "back" and the like indicate orientations or positional relationships based on orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
Fig. 1 and 2 show an end sealing structure of an insulating protective sleeve, which includes at least two sealing rings 3, the sealing rings 3 are detachably disposed on an inner wall of an end portion of a casing 2 of the insulating protective sleeve, specifically, an installation groove is disposed on an inner wall of an end portion of the casing 2 of the insulating protective sleeve, the sealing rings 3 are disposed in the installation groove, and a warning device 4 is disposed on an outer wall of the casing 2 of the insulating protective sleeve between the sealing rings 3; in this embodiment, warning device 4 adopts 5 detachable settings of screw thread on insulating protective cover casing outer wall, and threaded connection is conventional technical scheme, and concrete structure is no longer repeated.
In this embodiment, the seal ring 3 is an epdm seal ring.
In this embodiment, the water-swellable material 42 is a water-blocking yarn. The water-blocking principle of the water-blocking yarn is that the main body of the water-blocking yarn fiber can rapidly expand to form a large-volume gel when meeting water, and the gel has quite strong water-retaining capacity, so that the moisture is prevented from continuously permeating and diffusing, and the aim of blocking water is fulfilled
In this embodiment, the water-color-changing material 43 is a water-color-developing test paper.
Be equipped with warning device 4 between two sealing washer 3, under the daily condition, outside sealing washer 3 is ageing and then lose the leakproofness more easily, after steam passes first layer sealing washer 3, can be absorbed by meeting water inflation thing 42, meet water inflation thing on one side and inwards expand, be full of the space between electrical components 1 and the insulating lag casing 2, prevent that steam from further invading, the another side fuses with meeting water color change thing, it discolours to make to meet water color change thing, make the staff in daily patrolling and examining, can find the problem through transparent shell, in time change.
Example 2
Another end seal structure of an insulating protective cover is provided in this embodiment, which is different from embodiment 1 in that a water-soluble film 44 is provided between the water-swellable substance 42 and the inner wall of the housing 41 in this embodiment. The water-soluble film 44 is a conventional component, such as a polyvinyl alcohol film.
The provision of water-soluble film 44 prevents water-swellable articles 42 and water-color change articles 43 from falling into insulating shield casing 2 under normal conditions, rendering the function useless.
The present invention is not limited to the above embodiments, and based on the technical solutions disclosed in the present invention, those skilled in the art can make some replacements and transformations for some technical features without creative labor according to the disclosed technical contents, and these replacements and transformations are all within the protection scope of the present invention.
