Abstract

The utility model discloses a cable pipe orifice sealing device, which consists of a reducing sealing pipe and a water-swelling rubber sealing sleeve, wherein the reducing sealing pipe is shorter than the water-swelling rubber sealing sleeve, and is connected with the inside of the water-swelling rubber sealing sleeve; the internal diameter shape of the reducing sealing pipe on a combination part is the same as the external diameter shape of the water-swelling rubber sealing sleeve; and the water-swelling rubber sealing sleeve consists of two halves, and has an internal diameter which is the same as the external diameter of a sealed cable. By the reducing sealing pipe and the water-swelling rubber sealing sleeve (a chloroprene rubber product), when water outside a well tends to pass through the water-swelling rubber sealing sleeve, the water-swelling rubber sealing sleeve is quickly swelled and enlarged to seal the water outside the well, so that a cable pipe orifice can be simply sealed, and the cable pipe orifice sealing device is long in service life, convenient and practical, and has good effects.

Description

A kind of cable mouth of pipe plugging device

Technical field

The utility model relates to a kind of plugging device, relates in particular to a kind of cable mouth of pipe plugging device, belongs to the power industry technical field.

Background technology

In underground pipeline construction, normal water inlet, the seepage problem of occurring in the tunnel that is provided with along the line, the active well all is to carry out shutoff with materials such as foamed glue, cement to pipeline in the site operation at present, and effect is very undesirable.

Summary of the invention

In order to address the above problem, the purpose of the utility model is to provide a kind of cable mouth of pipe plugging device, adopts the combination of reducing shutoff pipe and hydro-expansive rubber sealing shroud that pipeline is carried out shutoff, and effect is very good.

The utility model solves the technical scheme that its technical problem adopted: a kind of cable mouth of pipe plugging device; Form by reducing shutoff pipe, hydro-expansive rubber sealing shroud; Connect in the hydro-expansive rubber Sealed casing pipe of reducing shutoff Guan Yuqi length less than self length, the internal diameter shape of its binding site reducing shutoff pipe is identical with hydro-expansive rubber sealing shroud external diameter shape.Described hydro-expansive rubber sealing shroud is made up of two halves, and its internal diameter is identical with institute shutoff cable external diameter.

The beneficial effect of the utility model is: owing to adopt reducing shutoff pipe and hydro-expansive rubber (a kind of neoprene based article) sealing shroud structure; When have outside the well water want through the time hydro-expansive rubber sealing shroud rapid expanding volume increase; With water blocking outside well; Thereby make the shutoff of the cable mouth of pipe very simple, the life-span is long effective, convenient and practical.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Fig. 1 is a kind of cable mouth of pipe of the utility model plugging device structural representation.

Fig. 2 is A-A cross-sectional view of Fig. 1.

Fig. 3 is the structural representation of installing and using of Fig. 1.

Label among the figure

1, reducing shutoff pipe 2, hydro-expansive rubber sealing shroud

3, cable 4, the work borehole wall.

Embodiment

See also Fig. 1 to Fig. 3; A kind of cable mouth of pipe plugging device; Form by reducing shutoff pipe, hydro-expansive rubber sealing shroud; Be connected in reducing shutoff pipe 1 and its length hydro-expansive rubber sealing shroud 2 pipes less than self length, the internal diameter shape of its binding site reducing shutoff pipe 1 is identical with hydro-expansive rubber sealing shroud 2 external diameter shapes.Described hydro-expansive rubber sealing shroud 2 is made up of two halves, and its internal diameter is identical with institute shutoff cable 3 external diameters.

Method for using: at first will need docking perhaps with cable by the position in active well of constructing or tunnel, multichannel be connected situation; Penetrate reducing shutoff pipe 1 from cable 3 terminations; The hydro-expansive rubber sealing shroud 2 of packing into and forming by two semicircles in reducing shutoff pipe 1 service position; Reducing shutoff pipe 1 internal diameter and hydro-expansive rubber sealing shroud 2 external diameters are fitted tightly by shape; Build active well or tunnel after fixing the position, make reducing shutoff pipe 1 and hydro-expansive rubber sealing shroud 2 naturally through the work borehole wall 4 or tunnel wall, all the other get final product by the normal operation construction.

Claims (2)

1. a cable mouth of pipe plugging device is made up of reducing shutoff pipe, hydro-expansive rubber sealing shroud; It is characterized in that: be connected in reducing shutoff pipe (1) and its length hydro-expansive rubber sealing shroud (2) pipe less than self length, the internal diameter shape of its binding site reducing shutoff pipe (1) is identical with hydro-expansive rubber sealing shroud (2) external diameter shape.
