Description

Technical Field

[0001] The utility model relates to the field of MPP power pipes, in particular to an MPP power pipe with an anti-slip structure. Background Art

[0002] MPP power pipe is also called MPP power cable protection pipe and MPP cable protection pipe. It is divided into trenchable and trenchless types. MPP trenchless power pipe is also called MPP jacking pipe or dragging pipe. It has the characteristics of high temperature resistance and external pressure resistance. MPP power pipe uses modified polypropylene as the main raw material. It does not require a large amount of mud, excavation and damage to the road surface. It is a construction project for laying pipelines and cables in special areas such as roads, railways, buildings, and under riverbeds.

[0003] MPP power pipes are the most widely used components in power engineering. However, when the current MPP power pipes are buried underground, it is difficult to prevent the cables laid inside from slipping. The cables inside the MPP power pipes are prone to rolling during the filling process, which will cause the cables to accumulate heat and affect the protection of the cables. Therefore, we propose an MPP power pipe with an anti-slip structure to solve the above problem. Utility Model Content

[0006] An MPP power pipe with an anti-slip structure comprises an MPP power inner pipe, the outer surface of the MPP power inner pipe is fixedly connected to the MPP power outer pipe, the inner ring of the MPP power inner pipe is fixedly connected to two limit seats, two limit holes are provided on the side surfaces of the two limit seats close to each other, an upper positioning seat and a lower positioning seat are respectively provided inside the MPP power inner pipe, and a plurality of anti-slip recessed holes are provided on the outer surface of the MPP power outer pipe.

[0007] In a further embodiment, the left and right ends of the upper positioning seat and the left and right ends of the lower positioning seat extend to the inside of the two groups of limiting holes respectively, and the side surfaces of the upper positioning seat and the lower positioning seat that are close to each other are in contact.

[0008] In a further embodiment, a groove is provided on the right side surface of the upper positioning seat and the right side surface of the lower positioning seat, and two positioning holes are provided on the side surfaces of the upper positioning seat and the lower positioning seat that are close to each other.

[0009] In a further embodiment, the MPP power inner tube comprises a polypropylene outer layer, and an inner ring of the polypropylene outer layer is fixedly connected to an armor layer.

[0010] In a further embodiment, the inner circle of the armor layer is fixedly connected to a metal steel mesh, and the inner circle of the metal steel mesh is fixedly connected to a polypropylene inner layer.

[0011] In a further embodiment, the outer wall size of the MPP power inner tube matches the inner wall size of the MPP power outer tube, and the outer surface of the MPP power outer tube is fixedly connected with equidistantly arranged reinforcement steel rings.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] Through the positioning seat and limiting holes provided inside the device, the lower positioning seat and the upper positioning seat can be installed in a limited position in the MPP power inner tube. At the same time, the lower positioning seat and the upper positioning seat, in cooperation with the two sets of positioning holes, can separate and position the cables in the MPP power inner tube, and perform anti-slip positioning on the cables laid inside the MPP power inner tube, thereby preventing the cables inside the MPP power inner tube from rolling during the filling process, causing the problem of heat accumulation in the cables, and improving the protection effect on the cables.
