Description

Technical Field

[0001] The utility model specifically relates to a PE cable protection tube and belongs to the technical field of PE cable protection tubes. Background Art

[0002] PE power cable protection tubes are widely used for external support and protection of buried high-voltage cables and street light cables; they are widely used in urban road construction, community development, garden landscape, enterprise construction and other places, as threading sheath tubes for cables such as electricity, street lights, lawn lights, garden lights, community intelligence, cable TV, communications and intelligent transportation; existing PE cable protection tubes, such as China Patent Authorization Announcement No.: CN217362419U, disclose a PE cable protection tube with strong toughness. By inserting two protection tubes into the connecting sleeve, the two protection tubes can be automatically positioned in the connecting tube, and the splicing of the two protection tubes can be achieved; another example is China Patent Authorization Announcement No.: CN216851181U, which discloses a wear-resistant PE cable protection tube with good insulation. The protection component can be used to fix the cable during use, and the extrusion force can be buffered when the cable is squeezed, thereby improving the protection of the cable, but the protection tube of this structure has general impact resistance and the construction is relatively cumbersome. Utility Model Content

[0003] In order to solve the above problems, the utility model proposes a PE cable protection tube, which has excellent corrosion resistance and wear resistance and can resist the impact force of the outside on the inner protection tube; thereby, it can protect the wired cables.

[0004] The PE cable protection tube of the utility model comprises:

[0005] Restraining hose;

[0006] A support pipe seat, the support pipe seat is engaged with both ends of the restraining rubber hose and bonded together; a semi-cylindrical clamping column is integrally formed inside the support pipe seat, and an Ω-shaped clamping groove is provided on the clamping column;

[0007] Inner protective tube; the outer part of the inner protective tube is integrally formed with a plurality of clamping strips, and the clamping strips are movably engaged with the clamping slots;

[0008] A corrugated plate, the corrugated plate is attached between the restraining hose and the inner protective tube; the corrugated plate is arranged between adjacent clamping columns, and the two ends of the corrugated plate protrude from the outer end of the inner protective tube;

[0009] The docking part includes an outer tube seat, a partition is integrally formed in the middle of the inner side of the outer tube seat, and an inner tube seat is integrally formed at the center of the partition; the tube diameter of the inner tube seat is consistent with the tube diameter of the inner protection tube; the support tube seat is embedded in the inner side of the outer tube seat and abuts against the partition, and the two ends of the inner tube seat abut against the ends of two adjacent inner protection tubes; the end of the corrugated plate abuts against the partition;

[0010] The restraining hose is made of a PE tube, and the inner protection tube is made of a HDPE tube.

[0011] During installation, first glue the support tube seat and the restraining hose together, then pass the inner protective tube through the support tube seat and the restraining hose; the clamping strip of the inner protective tube can be movably engaged with the clamping groove; the support tube seat, the restraining hose and the inner protective tube are assembled into one; then, the corrugated plate is passed through the gap formed by the restraining hose, the inner protective tube and the clamping strip in turn; finally, assemble the docking part with the support tube seat; during assembly, the outer tube seat is engaged with the support tube seat, and the inner tube seat and the inner protective tube are aligned; thereby completing the assembly of the entire PE cable protection tube; after the assembly, the end of the corrugated plate of the PE cable protection tube abuts against the partition, so that a slightly curved arch bridge structure is formed between the restraining hose and the inner protective tube.

[0012] The restraining hose is made of PE tube, which has excellent flexibility and is relatively soft overall. It is easily deformed by the backfill stone. Through the support of the corrugated plate and the dispersion of impact force, it can adapt to the impact of the stone wrapped in the backfill soil. Through the elastic deformation of the restraining hose and the corrugated plate, it can avoid direct impact on the inner protective tube. The inner protective tube is made of HDPE tube, which is many times stronger than the restraining hose. The impact resistance of the inner protective tube itself and the deformation of the hose and the corrugated plate are used to disperse the impact force, so that the entire PE cable protection tube has better impact resistance and is suitable for use in engineering projects in cold areas and harsh climatic conditions. It will not break due to external forces. The restraining hose and the inner protective tube are made of polyethylene material and high-density polyethylene material respectively, both of which have excellent corrosion resistance. The cable is routed from the inside of the inner protective tube. Since the HDPE molecular weight of the inner protective tube is high and the wear resistance coefficient is high, it can avoid the wear of the inner wall during the routing of the inner protective tube.

[0013] The corrugated plate increases the overall structural strength of the PE cable protection tube and can ensure the flexibility of the entire PE cable protection tube; when the restraining hose is deformed by impact, the impact force is transmitted to the corrugated plate; since the corrugated plate is supported on one side close to the inner protection tube, the impact force is transmitted to both ends of the docking part. Since the two docking parts support and limit the two ends of the corrugated plate, the corrugated plate forms a slightly curved arch bridge structure, which can further resist the external impact force on the inner protection tube; thereby protecting the inner protection tube.

[0014] Furthermore, the corrugated plate is cut into two sections at the turning point of the inner protective tube, and a spring body is arranged between the two sections of the corrugated plate; a spring bayonet is opened at one end of the two sections of the corrugated plate close to each other; the spring body is embedded in the spring bayonet, and the end of the spring body abuts against the inside of the corrugated plate. When the PE cable protection tube is bent according to the routing requirements, the corrugated plate is first cut off at the bending position; two sections of the corrugated plate are obtained, and holes are opened at one end of the two sections of the corrugated plate close to each other; then, the spring body is embedded in the two opening positions; and the corrugated plate and the spring body are embedded between the restraining hose and the inner protective tube; due to the action of the spring body, the PE cable protection tube can be bent.

[0015] Furthermore, the corrugated plate is a polycarbonate corrugated plate, which has strong impact resistance and can adapt to external impact and disperse impact stress.

[0016] Furthermore, the restraining rubber hose and the supporting pipe seat, and the supporting pipe seat and the butt joint are fixed by bonding or hot-melt welding.

[0017] Furthermore, both ends of the inner tube seat are integrally formed with an expanded diameter portion, the end of the inner protective tube is embedded in the expanded diameter portion and abuts against the inner wall of the expanded diameter portion; the end of the inner tube seat adopts an expanded diameter structure, which can facilitate the docking of the inner protective tube and the expanded diameter portion and improve the convenience of assembly.

[0018] Furthermore, the corrugated plate is an arc-shaped structure in the width direction that fits the inner wall of the constraining hose and the outer wall of the inner protective tube. The assembled corrugated plate can fit well to the inner wall of the constraining hose and the outer wall of the inner protective tube.

[0019] Furthermore, after the clamping strip is engaged with the clamping slot, the clamping strip fits the inner wall of the restraining hose; after the clamping strip and the clamping slot are assembled, the clamping strip can fit tightly with the inner wall of the restraining hose, so that the restraining hose, the clamping strip and the inner protective tube are integrated.

[0020] Compared with the prior art, the PE cable protection tube of the utility model has good overall corrosion resistance and wear resistance, and is assembled into one body by a restraining hose, a corrugated plate and an inner protection tube; the elastic deformation of the restraining hose and the corrugated plate can avoid direct impact on the inner protection tube; when the restraining hose is deformed by impact, a slightly curved arch bridge structure is formed by the installation of the corrugated plate, which can resist the external impact force on the inner protection tube; thereby, the inner protection tube can be protected; the entire PE cable protection tube has good wear resistance.
