Description

Technical Field

[0001] This utility model relates to the field of PVC power pipe technology, specifically to an extrusion-resistant PVC power pipe. Background Technology

[0002] PVC power pipe, also known as polyvinyl chloride power pipe, is a type of pipe material widely used in power engineering. PVC power pipe is widely used in urban power grid construction and renovation, urban municipal renovation projects, civil aviation airport construction, engineering park and residential area construction, transportation and road and bridge construction, and other fields. It is mainly used for laying and protecting cables to ensure the safe operation of cables.

[0003] For example, the utility model patent disclosed in publication number CN209461949U discloses a PVC power pipe, which includes an outer pipe and an inner pipe. Both the outer pipe and the inner pipe are made of polyvinyl chloride. The inner pipe is sleeved inside the outer pipe. A foamed insulation layer is provided between the outer pipe and the inner pipe. The foamed insulation layer is connected to both the outer pipe and the inner pipe. Supporting ribs are provided inside the foamed insulation layer. The supporting ribs are evenly distributed circumferentially and extend along the axial length. An insulation layer is provided between the foamed insulation layer and the inner pipe. A protective layer is provided on the outside of the outer pipe. The protective layer consists of a flame-retardant layer, a wear-resistant rubber layer, and an anti-corrosion coating from the inside to the outside. A glass fiber layer is sandwiched inside the wear-resistant layer. The beneficial technical effects of this utility model are: it has a foamed insulation layer, which has a good insulation effect and is tightly connected to the outer and inner pipes; it has supporting ribs to enhance the strength of the power pipe; it has an insulation layer to prevent signal interference; and it has a protective layer to provide flame retardancy, wear resistance and corrosion protection.

[0004] Although the aforementioned power pipes have certain anti-interference and fireproof properties, their internal radial support stability is insufficient. When subjected to external pressure, they are prone to deformation. Furthermore, the support ribs in the power pipes can only bear axial forces, which reduces the support stability of the power pipes. Therefore, there is an urgent need for an extrusion-resistant PVC power pipe to solve the above-mentioned problems. Utility Model Content

[0008] A support sleeve is fixedly disposed on the inner end face of the anti-compression device, and support ribs are provided at equal intervals on the inner end face of the support sleeve.

[0013] Preferably, the supporting ribs are made of high-density polyethylene, which can effectively improve the longitudinal support stability of the power pipe.

[0014] Preferably, the limiting inner tube and the supporting inner tube are made of polypropylene, which can effectively improve the internal strength and toughness of the power pipe, thereby improving the subsequent extrusion resistance of the power pipe.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. In this utility model, both the first reset mesh layer and the second reset mesh layer are elastic structures. When the outside of the power pipe is compressed, the first reset mesh layer and the second reset mesh layer can quickly and stably support the inside of the power pipe, thereby improving the stability of the power pipe reset. The transverse support ring, the limiting inner tube and the supporting inner tube are high-strength structures, which can effectively improve the overall strength of the power pipe body, thereby improving the extrusion resistance of the outside of the power pipe.
