Abstract
The invention discloses a cable guide. The cable guide comprises at least two single-wall corrugated pipes and telescopic joints for connecting every two adjacent single-wall corrugated pipes. Each telescopic joint comprises two connecting pipes respectively connected with one single-wall corrugated pipe and a communicating corrugated pipe arranged between the two connecting pipes, and a positioning boss extending in the axial direction of each connecting pipe is arranged in the position, connected with the communicating corrugated pipe, in the connecting pipe. A stainless steel hoop is arranged on the outer wall of each connecting pipe, and an annular outer groove for fixing the stainless steel hoop is formed in the outer wall of each connecting pipe. The cable guide further comprises sealing rings, wherein the sealing rings are fixed into grooves in the outer surfaces of the single-wall corrugated pipes, and the sealing rings and the inner walls of the connecting pipes form seals. The cable guide has the advantages that the capacity of a high-voltage electric cable for resisting soft foundation settlement and shear deformation of a geological abrupt change section is improved through the telescopic joints, structural safety of the cable guide is guaranteed, and thus the service life of the cable is prolonged, and normal running of electrical equipment is guaranteed.
Description
Technical field
The present invention relates to a kind of cable duct tube.
Background technology
The cable duct tube using is at present divided into two kinds, one is that rigid cable conduit is as compound glass steel conduit, plastic-coated steel, fibre-cement pipe, CM pipe etc., it allows differential settlement in 30mm left and right, and bellmouth amount of deflection, 2.5 ° of left and right, is applicable to the relatively stable cable passage of ground.Another kind is that flexible cable conduit is as carbon element bellows, chliorinated polyvinyl chloride or Vybak double-wall corrugated pipe, Modified polypropylene single-wall corrugated pipe etc., it allows differential settlement in 200mm left and right, be applicable to soft soil foundation cable passage, but the shearing deformation ability in its cytoplasmic mutation location, opposing ground is lower.If cable duct tube wrecks, will certainly have a strong impact on the fail safe of cable, cause unnecessary loss.
Summary of the invention
The object of the present invention is to provide a kind of cable duct tube, can effectively solve the low problem of the anti-shearing deformability of existing flexible cable conduit.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of cable duct tube, comprise at least two single-wall corrugated pipes with by adjacent two expansion joints that single-wall corrugated pipe is connected, the tube connector that described expansion joint comprises two respectively and single-wall corrugated pipe joins and be arranged on two diaphragm for passageway between tube connector, described tube connector is inner is provided with diaphragm for passageway joint the positioning boss extending to tube connector axis direction;
Described tube connector outer wall is provided with stainless steel anchor ear, has the outer groove of annular of fixing stainless steel anchor ear on described tube connector outer wall;
Also comprise and be fixed on the sealing ring that forms sealing in single-wall corrugated pipe outer surface groove with tube connector inwall.
Preferably, all have an annular inner groovy coordinating with sealing ring on described each tube connector madial wall, the air line distance of described annular inner groovy and the outer groove distance positioning boss of annular equates; The location that annular inner groovy can better be realized sealing ring, it is tightr that annular inner groovy can make sealing ring contact with annular inner groovy when equating anchor ear banding with the air line distance of the outer groove distance positioning boss of annular again, has better waterproof effect.
Preferably, the bottom of described annular inner groovy is waveform; The contact area that reduces annular inner groovy bottom and anchor ear, makes expansion joint can produce larger distortion, thereby single-wall corrugated pipe and expansion joint can more firmly be linked together.
Compared with prior art, advantage of the present invention is: the shearing deformation ability that has improved high voltage power cable opposing soft soil base sedimentation and cytoplasmic mutation location, ground by expansion joint is set between two single-wall corrugated pipes, can tackle cable passage significantly differential settlement produce time cable duct tube deformation even transition, guarantee the structural safety of cable duct tube, thereby improve the useful life of cable, ensure the normal operation of electric power facility; When can making single-wall corrugated pipe be connected with expansion joint, positioning boss can accurately locate, prevent that two single-wall corrugated pipes from inserting expansion joints and cross dark and lose anti-shearing deformability, utilize stainless steel anchor ear to pinch tight expansion joint, make expansion joint that certain deformation energy occur better to fix the relative position of single-wall corrugated pipe and expansion joint, be not subjected to displacement, utilize sealing ring to snap between single-wall corrugated pipe external waviness and expansion joint and form good sealing effectiveness, anti-sealing enters in pipe.
Brief description of the drawings
Fig. 1 is the structural representation of expansion joint in a kind of cable duct tube of the present invention;
Fig. 2 is the structural representation of a kind of cable duct tube of the present invention.
Embodiment
Consult the embodiment that Fig. 1, Fig. 2 are a kind of cable duct tube of the present invention, a kind of cable duct tube, comprise at least two single-wall corrugated pipes 1 and the expansion joint 2 that adjacent two single-wall corrugated pipes 1 are connected, the tube connector 3 that described expansion joint 2 comprises two respectively and single-wall corrugated pipe 1 joins and be arranged on two diaphragm for passageway 4 between tube connector 3, described tube connector 3 is inner is provided with diaphragm for passageway 4 joints the positioning boss 5 extending to tube connector 3 axis directions;
Described tube connector 3 outer walls are provided with stainless steel anchor ear 6, have the outer groove 7 of annular of fixing stainless steel anchor ear 6 on described tube connector 3 outer walls;
Also comprise and be fixed on the sealing ring 8 that forms sealing in single-wall corrugated pipe 1 outer surface groove with tube connector 3 inwalls.
On described each tube connector 3 madial walls, all have an annular inner groovy 9 coordinating with sealing ring 8, described annular inner groovy 9 and the outer groove 7 of annular are equal apart from the air line distance of positioning boss 5, and the bottom of described annular groove is waveform.
First sealing ring 8 is enclosed within on single-wall corrugated pipe 1, estimate the position of sealing ring 8 on single-wall corrugated pipe 1, insert at single-wall corrugated pipe 1 after the tube connector 3 of expansion joint 2, can make sealing ring 8 just in time be positioned at annular inner groovy 9, stainless steel anchor ear 6 snaps in the outer groove 7 of annular, then tightening stainless steel anchor ear 6, single-wall corrugated pipe 1 and expansion joint 2 are being fixed.By being set between two single-wall corrugated pipes 1, expansion joint 2 improves the shearing deformation ability in high voltage power cable opposing soft soil base sedimentation and cytoplasmic mutation location, ground, can tackle cable passage significantly differential settlement produce time cable duct tube deformation even transition, guarantee the structural safety of cable duct tube, thereby improve the useful life of cable, ensure the normal operation of electric power facility; When can making single-wall corrugated pipe 1 be connected with expansion joint 2, positioning boss 5 can accurately locate, prevent that two single-wall corrugated pipes 1 from inserting expansion joint 2 and excessively deeply losing anti-shearing deformability, utilize 6 pinches of tight expansion joints 2 of stainless steel anchor ear, make expansion joint 2 that certain deformation energy occur better to fix the relative position of single-wall corrugated pipe 1 and expansion joint 2, be not subjected to displacement, utilize sealing ring 8 to snap between single-wall corrugated pipe 1 external waviness and expansion joint 2 and form good sealing effectiveness, anti-sealing enters in pipe.
