It is expanded in gap between cable and access apertures, after seal body 10 swells, inner sidewall is bonded with cable, outside
Wall is bonded with the inner wall of access apertures, since the inner sidewall circumferentially of seal body 10 and lateral wall are that flexible material is made,
Therefore be between cable and access apertures after 10 deformation of seal body fit closely, thus by cable and access apertures inner wall it
Between gap fill up.
Compared with the mode being sealed in the prior art using anti-sapropel, using provided by the embodiment of the utility model close
The effect that seal apparatus seals the gap between cable and access apertures is more preferable, and the service life is longer.
In a kind of specific embodiment of the present embodiment, the inner sidewall circumferentially and lateral wall of seal body 10 are equal
It is made of rubber.Above-mentioned inner sidewall and lateral wall are for cable-through hole 20, and the inner sidewall of seal body 10 was
The hole wall of string holes 20, lateral wall are the side wall radially away from 20 side of cable-through hole.
In another specific embodiment of the present embodiment, the first retaining piece of 10 entirety of seal body and its inside
40 and sealing-plug 50 be made of rubber, sealing-plug 50 and opening 41 interference fit.
As depicted in figs. 1 and 2, the section of the lateral wall of seal body 10 is waveform.So set, seal body
10 lateral wall can deformation space it is bigger therefore inflatable bigger.
Further, the section of the bottom and top of seal body 10 may be set to be waveform.
As shown in figure 3, the first retaining piece 40 is annular, first chamber 31 and second chamber 32 are annular compartment, first
Chamber 31, second chamber 32 are parallel with the axis of cable-through hole 20.So set, may make sealing device expansion more uniformly, it is swollen
Swollen direction is mainly radial.
In one of embodiment of the present embodiment, first chamber 31 is located at 32 inside of second chamber, sealing-plug 50
It is located at second chamber 32 with the junction of drawstring 60.
In another specific embodiment of the present embodiment, second chamber 32 is located at the inside of first chamber 31, sealing
Plug 50 and the junction of drawstring 60 are located at second chamber 32.
Optionally, it is evenly arranged with multiple second retaining pieces in second chamber 32, is provided with through-hole on the second retaining piece, the
Second chamber 32 is divided into multiple interconnected sub-chamber by two retaining pieces.So set, may make in second chamber 32
Swelling agent is more uniformly spread, and swelling agent is avoided to concentrate on the same region.
Alternatively, in another embodiment specific implementation mode, first chamber 31 and second chamber 32 be provided with multiple second every
First chamber 31 and second chamber 32 are divided into multiple sub-chamber by block piece, the second retaining piece respectively, the son in first chamber 31
Sub-chamber in chamber and second chamber 32 is arranged in a one-to-one correspondence, the sub-chamber in every group of first chamber 31 being correspondingly arranged and
It is provided with an opening 41 on the first retaining piece 40 between sub-chamber in two chambers 32, is provided with sealing-plug in opening 41
50, sealing-plug 50 is connect with drawstring 60, and seal body is stretched out in one end of drawstring 60, and each drawstring 60 stretches out the one of seal body
End is divided into two groups, and one group of drawstring 60 is connect with a pull rod.When starting sealing device, while two pull rods are pulled open, by two
Group sealing-plug 50 pulls out, so that the water in the Liang Ge sub-chamber being correspondingly arranged is contacted with swelling agent, so that seal body
Expansion.So set, the expansion of seal body all directions can be made relatively uniform.
As shown in Figure 3 and Figure 4, the cable-through hole 20 of seal body 10 is circular hole.Cable passes through cable-through hole 20, due to cable
Section is also round, therefore the hole wall of the cable-through hole 20 of circular hole is bonded more closely after seal body expansion with cable.
When a branch of cable to be extend into inside power distribution cabinet by an access apertures, which can be passed through into sealing
The inside of power distribution cabinet is protruded into after a cable-through hole 20 on part ontology 10.
Alternatively, in another embodiment specific implementation mode, as shown in figure 4, seal body 10 is provided with multiple cable-through holes
20, the axis of each cable-through hole 20 is parallel.Each cable in a branch of cable is each passed through each cable-through hole 20, in seal body 10
After expansion, cable is not only filled between access apertures, is also filled between cable and cable.
When using sealing device, first sealing device can be covered on cable, cable is then protruded into being passed through for power distribution cabinet
After the completion of accessing cable, sealing device is pushed into access apertures along cable for hole, then pulls open sealing-plug 50 so that sealing
Device is expanded to be sealed.
Alternatively, in another embodiment specific implementation mode, flexible flange is respectively set in the axial two sides of seal body 10
70.So set, seal body 10 can first be protruded into access apertures, when seal body 10 is protruded into access apertures, wherein
Deformation occurs for side flexibility flange 70, and when flange 70 reaches the inside of power distribution cabinet, flange 70 springs back and restores to the original state, at this point,
The flange 70 of two sides fixes seal body 10 in a certain range relative to power distribution cabinet, then directly protrudes into cable close
The cable-through hole 20 of sealing ontology 10, since seal body 10 is located at access apertures, cable stretches out after cable-through hole 20
With regard to reaching on the inside of power distribution cabinet.It is not necessarily to change the position of seal body 10 after completing cable access, direct pull drawstring 60 makes
Seal body 10 is obtained to expand.It is easy to operate, it is high-efficient.
Embodiment two
The another object of the utility model embodiment two is to propose a kind of power distribution cabinet, existing in the prior art to solve
Between power distribution cabinet and cable the technical issues of poor sealing effect.
The power distribution cabinet that the present embodiment two provides, including cabinet body are provided with access apertures on cabinet body, and cable is protruded by access apertures
Cabinet body is provided with the sealing device such as above-mentioned technical proposal between cable and access apertures.
Specifically, access apertures is set to the bottom of cabinet body, and when accessing cable into power distribution cabinet, cable is first passed through sealing
The cable-through hole of device then passes through the access apertures of power distribution cabinet, after accessing cable, so that sealing device is located at cable and distribution
Between the access apertures of cabinet, drawstring is pulled, so that sealing-plug is extracted from the opening of the first retaining piece, so that opening is exposed,
First chamber is connected to second chamber, and water is contacted with swelling agent, is expanded after swelling agent water suction, so that first chamber and second
Chamber expansion, so that seal body swells.After seal body swells, inner sidewall is bonded with cable, lateral wall
It is bonded with the inner wall of access apertures, since seal body inner sidewall circumferentially and lateral wall are that flexible material is made,
It is to fit closely between cable and access apertures after seal body deformation, thus will be between cable and access apertures inner wall
Gap is filled up.
Therefore, compared with power distribution cabinet in the prior art, the power distribution cabinet that the present embodiment two provides passes through above-mentioned sealing device
It is sealed, sealing effect is good, affected by environment small, long service life.
