Abstract
The utility model relates to the technical field of the pipeline, and in particular relates to an MPP (modified polypropylene) power cable protection pipe. The MPP (modified polypropylene) power cable protection pipe includes a plurality of pipe bodies; two ends of each pipe body is respectively provided with a fixed column; the pipe bodies are connected by welding; a welding position of the pipe bodies is provided with a connecting device; and an inner side of the connecting device is provided with a fixed groove corresponding to the fixed column. The MPP (modified polypropylene) power cable protection pipe makes connection among the tube bodies connected together by welding be more reliable, and does not cause the tube body to easily fall; in addition, the MPP (modified polypropylene) power cable protection pipe has the advantages of better sealing performance, and more convenient disassembly and maintenance.
Description
Technical field
The utility model relates to pipe technology field, specifically a kind of MPP modified polypropene power cable protecting pipe.
Background technology
MPP power pipe is called again MPP cable tube or MPP power cable protecting pipe; employing modified polypropene is made; in prior art; adopt burying underground of MPP modified polypropene power cable protecting pipe to substitute traditional hollow pipe of cement; but burying underground in process of pipeline, between body and body, conventionally adopt bonding machine sweat soldering, but conventionally have weld cracking; after burying a period of time underground, can there is not prison welding, body obscission.
Utility model content
For above-mentioned weak point of the prior art, the utility model aims to provide a kind of fixing MPP modified polypropene power cable protecting pipe more easily.
For solving the problems of the technologies described above; MPP modified polypropene power cable protecting pipe of the present utility model; it comprises several bodys; described body two ends are provided with fixed leg; between body, adopt and be welded to connect; weld between body is provided with jockey, and jockey inner side is provided with the fixed groove of setting corresponding to fixed leg.
Concrete, described jockey inner side is also provided with annular groove, is provided with a gas-flow closure circle in this annular groove.
Described gas-flow closure circle comprises gas-flow closure circle body and is arranged at the gas-filled tube on gas-flow closure circle body.
Described jockey is that two symmetrical semi-circular ring and each equal one in semi-circular ring two ends are provided with fixed block, between semi-circular ring by bolt in the detachable connection in fixed block place.
MPP modified polypropene power cable protecting pipe of the present utility model; because body two ends are provided with fixed leg; weld between body is provided with jockey; jockey inner side is provided with the fixed groove of setting corresponding to fixed leg; so that between the body being welded to connect, connect more firm; be difficult for causing body to come off, in addition, the utility model also has advantages of that sealing property is better, demolition and maintenance are convenient.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the structural representation of the utility model MPP modified polypropene power cable protecting pipe;
Fig. 2 is the connection status schematic diagram of the utility model MPP modified polypropene power cable protecting pipe;
Fig. 3 is the structural representation of jockey in Fig. 2;
Fig. 4 is the structural representation of gas-flow closure circle in the utility model.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Embodiment based in the utility model, those of ordinary skills are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
As Figure 1-Figure 4; MPP modified polypropene power cable protecting pipe of the present utility model; it comprises several bodys 1; described body 1 two ends are provided with fixed leg 11; between body 1, adopt and be welded to connect; weld between body 1 is provided with jockey 2, and jockey 2 inner sides are provided with the fixed groove 21 with the corresponding setting of fixed leg 11.The utility model is because body 1 two ends are provided with fixed leg 11, weld between body 1 is provided with jockey 2, jockey 2 inner sides are provided with the fixed groove 21 with the corresponding setting of fixed leg 11, so that connect more firmly between the body being welded to connect 1, be difficult for causing body 1 to come off.
Concrete, described jockey 2 inner sides are also provided with annular groove, are provided with a gas-flow closure circle 3 in this annular groove.Described gas-flow closure circle 3 comprises gas-flow closure circle body 31 and is arranged at the gas-filled tube 32 on gas-flow closure circle body 31.It is tightr that gas-flow closure circle 3 makes jockey 2 be connected with body 1, and can dismantle, and during maintenance, can replace, not only easy to maintenance, and saved cost.
Described jockey 2 is that two symmetrical semi-circular ring and each equal one in semi-circular ring two ends are provided with fixed block 22, between semi-circular ring by bolt in the fixed block detachable connection in 22 places.Jockey 2 is mainly detachably for convenient for maintaining, and if gone bad a semi-circular ring, replace so another, saved production cost.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
