Description
Technical field
The present invention relates to a kind of electric power facility accessories, are specifically cable channel loss prevention sealing device.
Background technology
Current power cable installation uses underground laying method more；Power cable is mounted below ground horizontal stretching
In cable channel, and it is spaced apart draw ground from cable shaft, the power switch cabinet for being built in ground is connected, so as in a steady stream
Constantly provide required power supply to the user.
The installation of above-mentioned power cable, be by the way of first building up cable installation and cable be installed again, therefore cable need
Under the traction of carrying cable, enter cable channel from cable shaft and pull a certain distance (usually no less than 50 to 100 meters), then
Ground is up entrained back into from cable shaft；Due to being usually 90 degree or so of Non-smooth surface in the cable channel oral area position of cable shaft
Dog-ear, in addition the typically more coarse heaviness of power cable, mechanical equipment strength need to be used to pull, therefore the surface layer of power cable
Sheath, which is usually scratched, even generates score, and the insulation performance, water resistance and service life of power cable is caused to be subject to shadow
It rings.
The content of the invention
The technical problems to be solved by the invention are to overcome the shortcomings of above-mentioned background technology, provide a kind of cable channel loss prevention
Sealing device, the device should be able to effectively protect power cable in installation process, and with simple and practical in structure and cable tube
The characteristics of road is connected firmly.
Technical solution provided by the invention is：Cable channel loss prevention sealing device, it is characterised in that：The device includes tubulose
Body and with the integrally formed running-on of body one end nozzle；The internal diameter of the body outer diameter and mating cable channel
It matches, facilitates insertion into cable channel；The running-on expands bell mouth shape to the outer diameter to be stretched, to block the pipe of cable channel
Mouth edge, prevents it from damaging power cable in installation process.
The body makes backwards to one end of running-on has several to be distributed on circumferential crack；Each crack along generatrix direction
It stretches and penetrates through one end nozzle backwards to running-on.
Each to crack for elongated V-arrangement, the top perforation of V-arrangement is backwards to one end nozzle of running-on.
The groove around circumferencial direction is also made close to the position of running-on on the body outer circumference surface, is equipped in groove
The sealing strip of waterproof.
The cross section of the rubber strip is the inclined wedge shape of left thin right thickness, in favor of cable channel loss prevention sealing device and electricity
Grafting sealing between cable pipeline.
The body is more than the outer diameter 2-8mm of other end nozzle backwards to the outer diameter of one end nozzle of running-on, to be conducive to electricity
Preload installation of the cable pipeline loss prevention sealing device in cable channel.
The beneficial effects of the invention are as follows：The device provided can effectively protect power cable in installation process, make it each
Item performance and used life is unaffected, and can be substantially reduced the frictional force of power cable and cable channel, reduces installment work
Intensity；And the device is connected firmly with cable channel, and with sealing waterproof function, do not influence normal cable seal of tube dress also
That puts installs and uses.In addition, the configuration of the present invention is simple is practical, cost is not high, the welcome of unit on probation is received.

Specific embodiment
Cable channel loss prevention sealing device shown in the drawings；Body 1 including tubulose and with body one end nozzle one
Molding running-on 2；The body outer diameter and the internal diameter of mating cable channel matches, so that body is inserted into cable
Pipeline, and can be as far as possible close to the inner wall surface of cable channel；The running-on expands bell mouth shape to the outer diameter to be stretched, to block
The nozzle edge of cable channel prevents the nozzle edge of the cable channel in installation process from cutting to wear to hinder power cable.
Further, the body makes backwards to one end of running-on and has several to be distributed on circumferential to crack 5；Each crack
It stretches and is penetrated through backwards to one end of running-on along generatrix direction；Each to crack for elongated V-arrangement, the top perforation of V-arrangement is backwards to covering
One end nozzle of mouth.Size, the length of the V-arrangement determine depending on different size or as needed.It is opened due to devising this
Seam is provided with the leeway of flexible adjustment backwards to the diameter of running-on one end nozzle, and the facility of bigger is brought to installation.
Further, fluted 4 are also made close to the position of running-on on the body outer circumference surface, the groove is in circumference
It is directed around lopping；The sealing strip 2 of waterproof is installed, sealing strip is recommended (only to show rubber in Fig. 1 using rubber strip in groove
The cross section of item).
The cross section of the sealing strip is the inclined wedge shape of left thin right thickness, and relatively thin one side is located at body backwards to the one of running-on
End, guiding when being conducive to install and the sealing with cable channel；During installation, the sealing strip of inclined wedge shape can be adjacent to cable tube
Road inner wall is conducive to the grafting sealing between cable channel loss prevention sealing device and cable channel, ensures installation quality.
Further, the body is more than the outer diameter 2-8mm of the other end backwards to the outer diameter of one end nozzle of running-on so that
The outer circumference surface of body is in cone；After being inserted into cable channel, which can more closely be adjacent to the inner wall of cable channel, more
Be conducive to preload installation of the cable channel loss prevention sealing device in cable channel.
The present invention occupation mode be (referring to Fig. 5)：Before power cable is installed, A of the present invention is first inserted into electricity respectively
The nozzle at cable pipeline 7 (being embedded into ground 8) both ends, and the pushing that exerts a force is until the present invention is complete with cable channel both ends nozzle
Be adjacent to it is identical, with that can according to common construction method install power cable.
Since the dog-ear position at cable channel both ends nozzle position has been blocked by the running-on of the present invention, by external force traction
Power cable 6 (unit cable or multi-cable are bundled into one) is to be close to the smooth outer surface of running-on to be slided (such as
Direction shown in arrow in Fig. 5；One end of power cable is sent into the one side cable shaft pipeline opening of cable channel, electric power from ground down
The other end of cable up pulls under the stretching of traction equipment from the pipeline opening of opposite side cable shaft), power cable no longer occurs
The phenomenon that scratch, so as to protect power cable no longer impaired；It, still can be in the base of the present invention and after the installation present invention
Installed again on plinth cable tube sealing device (such as ZL201621012350.0, ZL201621012347.9 and
ZL201720133342.X)。
