Description
Technical Field
The utility model relates to an electric power facility protection device specifically is a plugging device of cable column pipe.
Background
A column tube (a lead tube) is a cable protection tube that is vertically fixed to the ground. In order to prevent rainwater from gathering inside the column tube to cause the cable to be soaked by water for a long time, and simultaneously prevent small animals or impurities from entering the inside of the column tube to damage the cable, plugging materials are required to be used for sealing the top of the column tube, so that the construction is complex, and the plugging materials are easy to fall off to cause plugging failure.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming not enough among the above-mentioned background art, provide a column casing plugging device, this plugging device should have simple to operate, the effectual characteristics of shutoff.
The technical scheme of the utility model is that:
column pipe plugging device, its characterized in that: the occluder comprises an upper sleeve and a lower sleeve which are coaxially arranged and fasteners which are respectively arranged on the upper sleeve and the lower sleeve; a first mounting seam is arranged in the bus direction of the upper sleeve and the lower sleeve, the inner diameter of the upper sleeve is smaller than that of the lower sleeve, and an end plate connected with the upper sleeve is arranged between the bottom surface of the upper sleeve and the top surface of the lower sleeve.
The plugging device further comprises a sealing gasket inserted into an inner cavity at the top end of the upper sleeve, a second mounting seam is arranged in the bus direction of the sealing gasket, and a flanging is arranged at the top of the sealing gasket.
The inner hole of the sealing gasket is an eccentric hole.
The outer circumferential surface of the top of the upper sleeve is provided with a first groove for mounting a fastener; the upper sleeve below the first groove is a corrugated telescopic pipe.
And a second groove for installing a fastener is formed in the outer circumferential surface of the lower sleeve.
The fastener is the staple bolt.
The utility model has the advantages that:
the utility model discloses install at the column casing top, can adjust according to the position and the size of cable, not only simple to operate, application scope are wide, and the shutoff is effectual moreover, long service life, has effectively ensured the safety of electric power facility.

Detailed Description
The present invention will be further described with reference to the drawings attached to the specification, but the present invention is not limited to the following embodiments.
As shown in fig. 1, the column pipe plugging device comprises an upper casing 1, a lower casing 2, a fastener 3 and a sealing gasket 6.
The upper casing 1 and the lower casing 2 are arranged up and down and are coaxially connected, the bottom surface of the upper casing is connected with the top surface of the lower casing through an end plate 5 which is horizontally arranged, the length of the upper casing is greater than that of the lower casing, and the inner diameter of the upper casing is smaller than that of the lower casing. The outer circumference of the top of the upper sleeve is provided with a first groove 9, and a corrugated expansion pipe is arranged below the first groove. And a second groove 10 is formed in the outer circumferential surface of the lower sleeve. And a first mounting seam 4 is arranged in the bus direction of the upper sleeve and the lower sleeve. The upper sleeve, the end plate and the lower sleeve are made of silicon rubber and are integrally formed.
The fastener adopts the staple bolt, and two staple bolts are installed respectively in first recess and second recess.
The sealing gasket 6 is intended to be inserted in the top cavity of the upper sleeve. The top of the sealing gasket is provided with a flange 8 which can cover the top surface of the upper sleeve, a second mounting seam 7 is arranged in the bus direction of the sealing gasket, the included angle between the wall surface of the second mounting seam and the tangent line in the circumferential direction is smaller than 90 degrees (generally 30-60 degrees), and the inner diameter of the sealing gasket is adjusted by arranging the two side wall surfaces of the second mounting seam in a staggered manner, so that the sealing gasket can wrap cables with different thicknesses. The sealing gasket is made of silicon rubber.
When laying cable 12 in pillar pipe 11, because there is the error, be difficult to guarantee that the cable just arranges in the pillar pipe center, lead to the cable all around different with the interval of pillar pipe inner wall, consequently set up the hole of sealing gasket into the eccentric orfice for axis B and the pillar pipe axis A parallel arrangement of sealing gasket, the thickness that makes the lateral wall all around of sealing gasket appear changing, guarantees that sealing gasket can closely laminate with the cable.
Install on the column casing the utility model discloses the time, will be earlier with the lower casing parcel on the column casing and will go up the sleeve pipe parcel on the cable, the column casing top need be pushed down to end plate between lower casing and the lower casing, again according to the sheathed tube length in the position adjustment of cable, then overlaps sealing gasket on the cable, fills in sealing gasket's bottom downwards in the upper casing to rotate sealing gasket according to the eccentric position of cable, install the staple bolt at last.
