Abstract
The utility model discloses a cable protection casing pipe. A pipe body of the cable protection casing pipe has a single-wall progressive thread-shaped structure, so the cable protection casing pipe can flexibly bend and twist to pass by barriers, and perfect flexibility enables the cable protection casing pipe to easily bend and twist to pass by the barriers to reduce ground breaking area, so even ground breakage or sinking occurs, safety is ensured; pipeline is not damaged; and construction is convenient. The cable protection casing pipe is enabled to have high compressive strength and is not deformed by heavy weight under ground. Products have great impact resistance. Interference rejection ability and high strength enable the pipeline to be safe even when an earthquake, the ground sinking, or the like occurs. According to the single-wall progressive thread-shaped structure, a contact area of cable and an inner wall of a pipe is enabled to be greatly small; a heat dissipation effect is great; an inner friction coefficient is small and just one eighth of that of a common straight pipe; internally-set guide wire can guide substantially long wire distance one time.
Description
Technical field
The utility model relates to technical field of electric wires and cables, more particularly, relates to a kind of cable protecting sleeve.
Background technology
The special-purpose tubing of the sheath of electric wire; Be mainly used in city street lamp circuit ground covering project; Electric railway electric power, telecommunication cable lay ground covering project; The project for construction and upgrading of highway electric power, communications facility, the cable protecting sleeve in the underground cable engineering of residential quarters construction project and park and large-scale public place of entertainment.
Straight scale pipe is effective as cable protective sleeve inside and outside the original many use steel pipes in this field, the PVC plastics, and this type of tubing cost cost is high, and inside and outside light directly causes the radiating effect in the cable work poor; And can only scale four meters or six meters, being limited to the particular requirement of transportation and production technology, the length of tubing can not be above 12 meters; And in such as rugged environment, should not construct; Can't the cut-through thing, very dangerous under the ground fracture or the situation of sinking, pipeline is very easily damaged.
Therefore, how to improve radiating effect, and can in rugged environment, construct, become the technical problem that those skilled in the art need to be resolved hurrily.
The utility model content
In view of this, the utility model provides a kind of cable protecting sleeve, with the raising radiating effect, and can in rugged environment, construct.
For realizing above-mentioned purpose, the utility model provides following technical scheme:
A kind of cable protecting sleeve, its body have the gradual thread-like structure of single wall.
Preferably, in above-mentioned cable protecting sleeve, the inwall of said body is a smooth structure.
Preferably, in above-mentioned cable protecting sleeve, the material of said cable protecting sleeve is a high-density polyethylene resin.
Preferably, in above-mentioned cable protecting sleeve, said cable protecting sleeve is an extrusion molding structure.
Can find out that from above-mentioned technical scheme the cable protecting sleeve that the utility model provides is because its body has the gradual thread-like structure of single wall; Make the flexible thing of cut-through freely; Good can turn to and walk around all kinds of obstacles easily around song property, reduces the area that breaks ground, even ground fracture or sinking are also very safe; Pipeline can be not damaged, convenient construction.And make its compression strength big, and can not be out of shape underground because of weight, product has stronger impact resistance, even disturbing property and high strength are also very safe under mutation situation such as earthquake or land subsidence.The gradual thread-like structure of single wall makes that cable and pipe material inner wall contact area are minimum, good heat dissipation effect, the internal friction coefficient is little, is merely 1/8 of normal straight tube, in establish the traction iron wire and once can introduce quite long line-spacing.
Description of drawings
The structural representation of the cable protecting sleeve that Fig. 1 provides for the utility model embodiment.
Embodiment
The utility model discloses a kind of cable protecting sleeve,, and can in rugged environment, construct with the raising radiating effect.
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
See also Fig. 1, the structural representation of the cable protecting sleeve that Fig. 1 provides for the utility model embodiment.
The cable protecting sleeve that the utility model embodiment provides, its body have the gradual thread-like structure 1 of single wall.
The cable protecting sleeve that the utility model provides; Because its body has the gradual thread-like structure 1 of single wall, make the flexible thing of cut-through freely, good can turn to and walk around all kinds of obstacles easily around song property; Reduce the area that breaks ground; Even ground fracture or sinking are also very safe, pipeline can be damaged, convenient construction.And make its compression strength big, and can not be out of shape underground because of weight, product has stronger impact resistance, even disturbing property and high strength are also very safe under mutation situation such as earthquake or land subsidence.The gradual thread-like structure 1 of single wall makes that cable and pipe material inner wall contact area are minimum, good heat dissipation effect, the internal friction coefficient is little, is merely 1/8 of normal straight tube, in establish the traction iron wire and once can introduce quite long line-spacing.
The inwall of body is a smooth structure, further to reduce the frictional force with cable.The material of cable protecting sleeve is a high-density polyethylene resin; Also can be multiple auxiliary materials such as high-density polyethylene resin and modification carbon element through the special single wall spiral tubing of producing with moulding process of extruding; Its production process mainly is to extrude through screw rod after the plastic extruder heat fused; And through the vacuum mold typing, tie up through winder then, put in storage then.Be that cable protecting sleeve is an extrusion molding structure.
Because the utility model is the extrusion molding structure, so joint length is long, can to reduce connector, can make quick construction according to any customized lengths of the actual instructions for use of client through circle formula disc collecting machine.
The utility model can be realized " lay earlier back threading " operation in laying construction, make that to wear cable safer, easy.Reserve pore make the user both the time demand settle at one go with planning at a specified future date.
The utility model just is with the special-purpose iron wire of a trailing cable line at random when producing, can make in the practice of construction process by the dress quick construction, and is easy to maintenance.
Each embodiment adopts the mode of going forward one by one to describe in this specification, and what each embodiment stressed all is and the difference of other embodiment that identical similar part is mutually referring to getting final product between each embodiment.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation of spirit that does not break away from the utility model or scope in other embodiments among this paper.Therefore, the utility model will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
