Abstract

The utility model discloses a cable protecting tube, aiming at overcoming the shortcomings of the conventional cable protecting tube that the construction spends much time and effort, accessories are high in cost, and the tube is easily flattened. According to the technical scheme, the cable protecting tube comprises an outer tube, an inner tube and a plurality of cable penetration tubes, wherein the inner tube and the plurality of cable penetration tubes are sleeved in the outer tube; the inner tube and the outer tube are coaxial; the plurality of cable penetration tubes are peripherally arranged along the inner wall of the outer tube; and the outer sides of the plurality of cable penetration pipes are connected with the inner wall of the outer tube while the inner sides of the plurality of cable penetration pipes are connected with the outer wall of the inner tube. The cable protecting tube has the advantages that manpower can be saved during carrying and embedding of the tube, a construction process of arranging and fixing a support is omitted, and the cost of the accessories is saved; single-layer protection for the tube is replaced by double-layer protection with the cable penetration tubes and the outer tube, thus the cable protecting tube can bear higher pressure; when the cable protecting tube is extruded by external force, the inner tube also plays a role in pressure buffering, and thus the cable penetration tubes are not easy to be flattened; and the cable penetration tubes are peripherally arranged along the inner wall of the outer tube, so that electric eddy current induction and cable heat can be alleviated since cables are prevented from being arranged in rows or ranks.

Description

Cable protection pipe

Technical field

The utility model relates to power domain, specifically a kind of cable protection pipe.

Background technology

Present most of cable all is laid on underground, for the protection cable is not subjected to artificial or natural damage, generally at the periphery of cable suit protection tube.Existing cable protection pipe is monotrysian type tubing; when the cable way of needs laying is more; with tubing 1 ＇ of many monotrysian types side by side or hierarchal arrangement, per two meters are fixed as an integral body by fixed support 2 ＇ on its length direction, and multiway cable is laid on respectively in many tubing 1 ＇.

Also there are some problems in actual use in existing cable protection pipe: first, during construction, the operation of pre-buried and per two meter amperes dress fixed support 2 ＇ of many tubing 1 ＇ takes time and effort, and, a large amount of uses of fixed support 2 ＇ also so that the accessory cost of cable protection pipe greatly increase; The second, cable protection pipe is when layering is pre-buried, and it is maximum that every tubing 1 ＇ will bear the tubing pressure-bearing of pressure, the particularly bottom, construction wrong slightly arranged with regard to the problem that easy generation tubing is crushed, and causing constructing, it is obstructed to wear cable after complete; The 3rd, the arrangement mode of this cable protection pipe also so that cable also thereupon in a row or arow lay, multiway cable is parallel, forms the current vortex induction, produces large calorimetric, especially lays centremost cable, heat production is maximum, can consume a large amount of electric energy.

Summary of the invention

Technical problem to be solved in the utility model is to overcome the defective that above-mentioned prior art exists, and provides time saving and energy saving in a kind of work progress, and cost is low, and tubing is difficult for being crushed, and can effectively reduce the cable protection pipe of cable heat production.

For this reason, the technical solution adopted in the utility model is as follows: cable protection pipe, its technical characterictic be, it comprises that outer tube, inner tube and Duo Gen wear the cable pipe, and inner tube and Duo Gen wear the cable pipe and all overlap within the outer tube, inner tube and outer coaxial tube setting; Wear the cable pipe for many and circumferentially arrange along the inwall of outer tube, its outside all is connected with the inwall of outer tube, and its inboard all is connected with the outer wall of inner tube.

Adopt the cable protection pipe of above structure compared with prior art, have the following advantages: first, with many monotrysian type tubing fixedly the structure optimization of bunchy be the integral structure that many of an outer tube inner sleeve is worn the cable pipe, simple in structure, the carrying of tubing and the pre-buried manpower of all having saved have also reduced the working procedure of mounting and fixing bracket, and construction schedule is fast, save a large amount of fixed supports, provide cost savings; The second, make outer tube into by the protection of the tubing of individual layer and add the double shielding of wearing the cable pipe, so that the pressure-bearing of this cable protection pipe is larger, when being subjected to the external force extruding, inner tube also plays the effect of pressure buffer, makes to wear the cable pipe and be difficult for being crushed; The 3rd, wear the cable pipe and circumferentially arrange along the inwall of outer tube, avoided behind the cable laying in a row or become row, reduced the current vortex induction, reduced the cable heat production.

As improvement, the wall thickness of described outer tube is greater than the wall thickness of inner tube; The wall thickness of outer tube is greater than the wall thickness of wearing the cable pipe.This setting so that the sound construction of outer tube is more reliable to the protection of wearing the cable pipe, is difficult for being crushed or damaging.

As improvement, described cable protection pipe also comprises many first reinforcements, and an end of many reinforcements all is connected with the inwall of outer tube, and the other end all is connected with the outer wall of inner tube.This setting is worn the distortion of cable pipe by what reinforcement had reduced that external force causes, more is difficult for being crushed so that wear the cable pipe.

As improvement, the quantity of described the first reinforcement equates with the quantity of wearing the cable pipe, and the first reinforcement with wear cable pipe interval and arrange.This setting is so that reinforcement is to the support of outer tube, firm better effects if.

As improvement, the cable pipe worn by described outer tube, inner tube, many and many first reinforcements are formed in one.This setting is so that this cable protection pipe is easy to process.

As improvement, also be provided with the second reinforcement on the inwall of described inner tube.This setting is so that the sound construction of inner tube is not yielding.

As improvement, described the second reinforcement is two blocks of mutually perpendicular plates, and the side of plate all offsets with the inwall of inner tube.This setting, so that the second reinforcement is simple in structure, better effects if.

The beneficial effects of the utility model are mainly reflected in: time saving and energy saving in the work progress, save cost, and tubing is difficult for being crushed, and can effectively reduce the cable heat production.
