Abstract
The utility model relates to a sealing device for an inflatable cable pipeline, comprising a strip-shaped inflatable seal bag and a film layer installed on the inflatable seal bag and extending along at least one side of the inflatable seal bag. Film layers are arranged on two sides of the inflatable seal bag. An inflatable pipe penetrating the inflatable seal bag and leading into the inflatable seal bag is arranged outside the inflatable seal bag. The sealing device of the inflatable cable pipeline is provided with the inflatable seal bag structure, therefore, after being inflated and installed, the seal device for the inflatable cable pipeline can offer a clean and dry environment immediately via an inflatable pipe stopper after being inflated and mounted, and later waste of procedure and time for pumping water firstly before hand hole construction can be avoided. Meanwhile, the sealing device of the inflatable cable pipeline can effectively prevent water from penetrating and flowing into the hand hole of equipment, a transformer substation basement or the power receiving room on the user side.
Description
Technical field
The utility model relates to a kind of sealing device, particularly relates to a kind of sealing device of Puffer-type cable duct.
Background technology
The cable duct that uses in the prior art all is in the middle of the environment of many water or humidity usually.And cable runs through or passes through the people's hand hole or the wall hole of equipment in use through regular meeting.At present, the sealing condition of cable duct does not all improve in long time, makes in the cable duct both sides or a certain side be in for a long time in the environment of humidity, many water.And when needs are constructed to this position, often at first draw water earlier, dehumidify, just can carry out construction working then, wasted a large amount of time and artificial.
The utility model content
The purpose of this utility model is, overcomes the defective of above-mentioned prior art and the sealing device of the Puffer-type cable duct that a kind of structure is extremely simple, sealing effectiveness is good and easy and simple to handle is provided.
For achieving the above object, the utility model is taked following design:
A kind of sealing device of Puffer-type cable duct comprises the inflation envelope of strip and extends and be arranged on film layers on the described inflation envelope along at least one side of described inflation envelope.
Preferably, on the relative both sides of described inflation envelope, be equipped with film layers.
More preferably, described inflation envelope outside also is provided with the gas-filled tube that passes described inflation envelope and lead to inflation envelope inside.
Preferably, the gas-filled tube place of exposing of described inflation envelope inside is provided with layer of silica gel.
Preferably, described inflation envelope is the stratiform envelope structure of being made by soft metal level and layer high molecule material layer.
The utility model has the advantages that: because the utility model is provided with the sealing bag structure of gas-filled type, therefore, after the utility model is being inflated and is being installed, by the gas-filled type pipe close, just can provide a clean and dry environment immediately, and get operation waste and the time waste that draws water earlier before exempting people's hand hole construction in the future.Simultaneously, the utility model can also prevent seepage effectively and flow into equipment people's hand hole, transformer station's basement or user side be subjected to the electricity indoor.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Embodiment 1:
Referring to Fig. 1, the preferred embodiment of the sealing device of a kind of Puffer-type cable duct of the utility model shown in it comprises the inflation envelope 1 of strip and extends and be arranged on film layers 2 on the described inflation envelope 1 along at least one side of described inflation envelope 1.Preferably, on the relative both sides of described inflation envelope 1, be equipped with film layers 2.Further, described inflation envelope 1 outside also is provided with the gas-filled tube 3 that passes described inflation envelope 1 and lead to inflation envelope 1 inside.And gas-filled tube 3 places of exposing of described inflation envelope 1 inside are provided with the layer of silica gel (not shown).After having dashed gas, directly gas-filled tube 3 is pulled out, just can utilize the fusion characteristics of layer of silica gel, gas-filled tube 3 is in the aperture that stays after pulling out merges sealing, prevent gas leakage.
Inflation envelope 1 described in the utility model is the stratiform envelope structure of being made by soft metal level and layer high molecule material layer.This kind structure helps improving inflation envelope 1 pliability of the present utility model and sealing.
Particularly, when bringing into use, do not pour gas in the inflation envelope 1 of the present utility model, the laminated structure that described inflation envelope 1 is elongated or annular.
In the process of using, at first the sheet inflation envelope 1 with the utility model strip or annular is wrapped in the cable outside to be sealed; Then, after envelope 1 sends into cable duct in the lump with described cable and inflation, carry out pneumatic compression.If the cable duct inwall is comparatively smooth and cleaning, just directly can realize the effect of hermetically-sealed cable pipeline by the deformation that produces between inflation envelope 1 after the inflation pressurization and the cable duct.
Embodiment 2:
The difference of present embodiment and the foregoing description is: extend and be arranged on film layers 2 on the described inflation envelope 1 along at least one side of described inflation envelope 1, present embodiment is provided with film layers 2 in the inboard of inflation envelope 1.During use, at first will inflate envelope 1 and be the outside that is fixed on cable to be sealed around shape by film layers 2; Then, carry out pneumatic compression.So can fix the relative position of described inflation envelope 1 and cable.
Embodiment 3:
The difference of present embodiment and the foregoing description is: the inside and outside both sides at described inflation envelope 1 are equipped with film layers 2, so just, inflation envelope 1 outside of cable to be sealed can be fixed on earlier, and then the inside that envelope 1 and cable are fixed on cable passage jointly will be inflate by the film layers 2 of arranged outside.Thereby can realize inflating the dual-seal in envelope 1 inboard and the outside, reach better sealing effectiveness.
Obviously, those of ordinary skill in the art can constitute various types of sealing devices with the sealing device of a kind of Puffer-type cable duct of the present utility model.
The foregoing description is only for the usefulness that the utility model is described; and be not to be to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from the utility model scope; can also make various variations and modification; therefore all technical schemes that are equal to also should belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
