As a kind of preferred version, described end cap comprises the first end cap and the second end cap, described the first end cap with the second end cap all for becoming circular flat board by two semicircular ring flat sheet combinations, described the second end cap is fixedly connected with a circular baffle plate, is provided with inlay card and seals up the sealant to inner-walls of duct space by cable outer layer between baffle plate and the first end cap.
Improved, described sealant is the airbag being wrapped on cable outer wall.
Improved, described sealant is that anti-cement or marine glue are glued between cable outer wall and duct wall.
Improved, the second described end cap extends and is connected and fixed to circular baffle plate at the connecting portion of two semicircular ring flat sheet combinations.
Improved, the extension that described the second end cap two halves annulus flat board extends to circular baffle plate is provided with prominent muscle, and described prominent muscle is arranged on the junction of baffle plate for fixing described circular baffle plate.
As another preferred version, the junction of described end cap two halves annulus flat board is provided with strip sealant, described cable and by being provided with annular seal layer between the dull and stereotyped circular end cap forming of two semicircular ring, is provided with annular seal layer between described circular end cap and duct wall.
Adopt after technique scheme, the utlity model has following advantage:
The end cap of sealing device described in the utility model is made up of two semicircular ring flat boards, easy for installation, and described sealant is according to the space layout between inner-walls of duct and cable, carry out sealing arrangement, effectively save the use of inlet seal material, and simple in structure, and sealing effectiveness is good.

Embodiment
A kind of cable duct sealing device, comprise the end cap 2 that prevents biotic intrusion for covering the cable 1 pipeline mouth of pipe, for convenience of the installation of end cap 2, described end cap 2 is divided into two semicircular ring flat boards, described two are semicircle dull and stereotyped by the circular end cap of being connected to form of the connectors such as bolt, described cable 1 is worn the annulus hole of penetrating described end cap 2, and described end cap is also provided with the sealant 8 for waterproof.Use so respectively end cap 2 to prevent that the biologies such as reptile from entering breaking-up cable and water-tight equipment in pipeline, can effectively safeguard that the long-time of sealing device effectively used.Adopt sealant 8 to carry out waterproof, effectively avoided water in prior art to pour in down a chimney the problem that enters cable duct.As long as end cap 2 adopts metal or the hard plastics such as such as aluminium, and sealant can adopt anti-cement or waterproof glue etc., on material, need to meet waterproof and hard material compared to prior art, choice requirement reduces, and has reduced material cost simultaneously.Certainly in the selection at cable duct sealing device, also can consider safety issue, conventionally select to have the material of fire-proof function, so the selection of common end cap and sealant material also can be considered flameproof effect.Compare, such as end cap is selected the metal materials such as aluminium, and sealant can be selected waterproof mud.
Below there is the cable duct sealing device of two different structures, certainly can be replaced by the sealing device of other structure with identical function.
Embodiment 1:
Referring to Fig. 1 and Fig. 2, in the present embodiment, described end cap 2 comprises the first end cap and the second end cap, described the first end cap is with the second end cap all for becoming circular flat board (referring to Fig. 3) by two semicircular ring flat sheet combinations, and two described semicircular ring flat boards are formed by fixedly connecting by bolt 5 and nut 6.Described the second end cap is fixedly connected with a circular baffle plate 3, and by bolt 4, the second end cap is fixedly attached on circular baffle plate 3.For making baffle plate 3 easy for installation, the mode that same baffle arrangement also can adopt two semicircular ring flat sheet combinations to be formed by connecting.Between baffle plate 3 and the first end cap, be provided with inlay card and seal up the sealant 8 to inner-walls of duct space by cable outer layer.Prevent biological invasion by end cap 2, by sealant waterproof, simple in structure, and first the second end cap is installed when mounted, then circular baffle plate 3 is fixedly connected on the second end cap by bolt 4, reinstall sealant 8, now by being installed, the first end cap seal fixes, and easy for installation, good sealing effect, and the choice requirement of encapsulant is reduced, reduced widely cost.
As a kind of preferred implementation, described sealant 8 is for being wrapped in the airbag on cable 1 outer wall.After having twined airbag, airbag is blown afloat and make the inner side of airbag inlay card at duct wall, make airbag Expansion sealing live inner-walls of duct and the second end cap to install the gap of rear existence, then the first end cap gland is sealed and fixed on airbag, easy for installation, and sealing effectiveness is good.
As another kind of preferred implementation, serve as reasons anti-cement or marine glue of described sealant 8 is glued between cable 1 outer wall and duct wall 7.
The second described end cap extends and is connected and fixed to circular baffle plate 3 at the connecting portion of two semicircular ring flat sheet combinations.Extend and be connected and fixed to circular baffle plate 3 by connecting portion, can make the second end cap and circular baffle plate 3 in the time being connected, have a stable support, connect more stable.
Easy to connect while connection by bolt 4 with circular baffle plate 3 for convenience of the second end cap, the extension extending to circular baffle plate 3 at described the second end cap two halves annulus flat board is provided with prominent muscle, and described prominent muscle is arranged on the junction of baffle plate for fixing described circular baffle plate 3.
Embodiment 2:
Referring to Fig. 4 and Fig. 5, strip sealant 8 is inserted in the gap of the direct junction at described end cap 2 two halves annulus flat boards, be provided with annular seal layer 8 at described cable 1 and between by the dull and stereotyped circular end cap 2 forming of two semicircular ring, between described circular end cap 2 and duct wall 7, be provided with annular seal layer 8.The all places that may produce gap of end cap are sealed.Compared to embodiment 1, the present embodiment only exists the place in gap to be provided with sealant at end cap, has greatly saved encapsulant, has reduced cost.
Except above preferred embodiment, the utility model also has other execution mode, those skilled in the art can make various changes and distortion according to the utility model, only otherwise depart from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
