Abstract
The utility model relates to a sealing device for a pipe mouth of a cable, which is used for carrying out waterproof treatment on an end enclosure of a threading pipe. The sealing device is characterized in that two or more bolts are fixed on a moving plate; bolt holes corresponding to the bolts are arranged on a fixed plate opposite to the moving plate; and sealing mud for sealing is filled between the moving plate and the fixed plate. The sealing device has the advantage of favorable sealing effect and is convenient to use and dismount. According to the technical scheme, by using the principle of using the sealing mud to extrude and deform, the sealing mud filled between the moving plate and the fixed plate is deformed by extrusion and is combined with the inner wall of the threading pipe of the cable and the cable, so that the sealing effect can be achieved. When the sealing device with the structure is detached, the sealing device is easily and integrally taken out by unscrewing the nuts.
Description
Technical field
When the utility model relates to the provided underground cable, the penetration pipe termination is carried out the cable conduit mouth sealing device of water-proofing treatment.
Background technology
At present, attractive in appearance for the city all laid various electric wires, cable by underground pipe network.Because the pipe networks that permeate the ground such as rainwater, greening water, bleed water, underground water, the transition joint of various underground pipe networks is ducked in drink for a long time, have a strong impact on the life-span of cable intermediate joint, even it is accidents caused, normal use to electric wire, caused very big threat, when cable enters in the regulator cubicle by underground pipe network simultaneously, also needed the incoming line of cable is carried out closed processes.Cable duct antiseep shutoff commonly used at present is to adopt the stifled mudding of fire prevention stifled, and according to the situation of long-term use, mainly have following problem: 1, shutoff length is too short, cause and infiltrate a lot of water in the penetration pipe, when the too much hydraulic pressure of ponding was excessive simultaneously, the stifled mud of fire prevention can be washed open, causes shutoff to lose efficacy; 2, if the too much of mud filling blocked up in fire prevention, though the problem that has solved seepage and gone out by ponding can cause when backup line comes into operation, the stifled mud of filling is difficult to take out, and causes the uneconomical of cost simultaneously; 3, because cable enters the closed processes in the regulator cubicle, the technical barrier of deliquescing slump distortion after long-time running, can occur, need periodic maintenance, bring inconvenience to production.
Summary of the invention
The purpose of this utility model is to overcome the defective that prior art exists, and a kind of good sealing effect, cable conduit mouth sealing device convenient to remove are provided.
For achieving the above object, the technical solution of the utility model is: a kind of cable conduit mouth sealing device, it is characterized in that, be fixed with two or more bolts on the portable plate, relative with portable plate decide to have on the plate and the corresponding bolt hole of bolt, at portable plate and decide to be filled with between the plate shutoff mud that is used to seal.
Above-mentioned portable plate and decide second portable plate also is housed between the plate has on second portable plate and decides that plate is corresponding to be used for second bolt hole that bolt passes.
Above-mentioned portable plate and decide all to have on the plate the corresponding through wires hole that cable passes that is used for.
Above-mentioned portable plate, decide on the plate and second portable plate, have the through wires hole that cable passes that is used for of mutual correspondence.
Characteristics of the present utility model are: 1, easy to use, good sealing effect.The technical program is to utilize the principle of shutoff mud crimp, the portable plate of putting into the cable penetration pipe and be installed in cable penetration pipe end face decide be filled with shutoff mud between the plate, driving portable plate by bolt moves, make the back distortion that is squeezed of shutoff mud between two plates, combine closely with cable penetration pipe inwall, reach sealing effectiveness.Portable plate is used for the through wires hole that cable passes with deciding to have on the plate as required, and when extruding shutoff mud, shutoff mud will be combined closely with cable penetration pipe inwall, cable, reaches sealing effectiveness like this.And, can at portable plate and decide to increase between the plate portable plate for the cable penetration pipe of big caliber, realize sealing effectiveness; 2, convenient disassembly.When this structure is dismantled at needs, only need nut is unclamped, just be easy to the whole taking-up of this plugging device.

Embodiment
Embodiment 1:
As shown in Figure 1, when not adorning cable in the cable penetration pipe, portable plate 2 is placed in the cable penetration pipe 1, the left end of two bolts 4 is fixed on the portable plate right side, decide plate 5 and be installed in the right side of cable penetration pipe 1, the right-hand member of two bolts passes the bolt hole of deciding to open on the plate, at portable plate 2 and decide to be filled with between the plate 5 the shutoff mud 3 that is used to seal.When the nut 6 installed on the rotating bolt right-hand member, portable plate moves right under the drive of bolt, extruding shutoff mud, be extruded like this after the distortion of shutoff mud, combine closely with cable penetration pipe inner wall surface, thereby reach the purpose of sealing.When needs are pulled down plugging device, in cable penetration pipe 1, again during threading, only need nut 6 is unclamped, bolt is moved to the left, be moved to the left thereby drive portable plate, just this plugging device can be pulled down.
Embodiment 2:
As shown in Figure 2, on the basis of embodiment 1, at portable plate 2 and decide to have increased between the plate 5 bolt hole that 8, three bolts of second portable plate pass second portable plate and decide to have on the plate 5.At portable plate 2 and two portable plates, two portable plates and decide to be filled with between the plate shutoff mud 3 that is used to seal.When the nut 6 installed on the rotating bolt right-hand member, portable plate moves right under the drive of bolt, extruding portable plate and two portable plate shutoff mud, two portable plates move right simultaneously, push two portable plates and decide shutoff mud between the plate, such two sections be extruded after the shutoff mud distortion, combine closely with cable penetration pipe inner wall surface, thereby reach the purpose of sealing.When needs are pulled down plugging device, in cable penetration pipe 1, again during threading, only need nut 6 is unclamped, bolt is moved to the left, be moved to the left thereby drive portable plate, just this plugging device can be pulled down.
Embodiment 3:
Shown in Fig. 3,5, when being installed with cable in the cable penetration pipe 1, on the basis of embodiment 1, portable plate 2, decide all to have on the plate 5 through wires hole 9, cable 2 passes above-mentioned two through wires holes respectively, is filled with the shutoff mud 3 that is used to seal at portable plate 2, in the confined space deciding between plate 5, cable penetration pipe inwall and the cable 2 to form.Under right-hand member fell female 7 effect, portable plate moved right, extruding shutoff mud, thus reach the purpose of sealing.
