[0001] This utility model relates to the field of cable protection pipe technology, specifically a high-strength insulated PE cable protection pipe. Background Technology

[0002] In modern society, power systems are widely used in various fields, from industrial production to residential life, from urban infrastructure to power supply in remote areas. Stable power transmission is crucial. As an important carrier of power transmission, cables need to be effectively protected to ensure their safe and reliable operation. Cable protection pipes are important devices used to protect cables. They can provide mechanical protection, insulation protection, and corrosion resistance to cables, extend their service life, and reduce the probability of failure.

[0003] Traditional cable protection pipes are made of ordinary PVC pipes. When subjected to large external impacts, including mechanical collisions and long-term vehicle running over them, they are prone to cracking and deformation, resulting in the exposure of the internal cables. Furthermore, since PE protection pipes are buried underground, the single-layer material cannot provide sufficient compressive strength and is prone to deformation, affecting the normal operation of the cables. Summary of the Invention

[0004] The purpose of this utility model is to provide a high-strength insulated PE cable protection pipe to solve the problems mentioned in the background art, which are prone to cracking and deformation when subjected to large external impacts, including mechanical collisions and long-term vehicle running over them, resulting in the exposure of the internal cable. Furthermore, since the PE protection pipe is buried underground, the single-layer material is difficult to provide sufficient compressive strength, making it prone to deformation and affecting the normal operation of the cable.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-strength insulating PE cable protection pipe, including a protective sleeve, which is the main structure of the cable protection pipe. The protective sleeve is a cylindrical structure, and the cable passes through the inside of the protective sleeve.

[0006] Rubber rings are equidistantly arranged on the outer wall of the protective sleeve, and two insulating arc-shaped plates are sleeved inside the protective sleeve. A reinforcing bracket is arranged between the two insulating arc-shaped plates, and the reinforcing bracket is arc-shaped.

[0007] The insulating arc-shaped plate is penetrated by a limiting steel cable, and each end of the limiting steel cable passes through an insulating ring. The insulating ring is inserted into one end of the protective sleeve, and a sealing ring is provided on the outer sleeve of the insulating ring. The insulating ring abuts against the insulating inner tube, and a positioning groove is provided on the surface of the insulating inner tube.

[0008] By adopting the above technical solution, the limiting steel cable, insulating ring, sealing ring and insulating inner tube and other structures work together to enhance stability and further strengthen insulation effect, so as to ensure the safe operation of the cable.

[0009] Preferably, the protective sleeve has an insulating arc-shaped plate and a reinforcing bracket inside, and the two insulating arc-shaped plates and the reinforcing bracket form a ring structure.

[0010] By adopting the above technical solution, the two insulating arc plates and the reinforcing bracket form a ring structure, which creates a stable mechanical support frame inside the protective sleeve, can evenly distribute external pressure, and significantly improve the pressure resistance of the protective sleeve.

[0011] Preferably, the reinforcing bracket is equidistantly arranged between two insulating arc-shaped plates, and an insulating inner tube is fitted inside the insulating arc-shaped plates and the reinforcing bracket.

[0012] By adopting the above technical solution, the support is set at equal intervals between the two insulating arc plates, which further optimizes the mechanical distribution and ensures the overall strength balance of the protective tube.

[0013] Preferably, the two ends of the limiting steel cable are L-shaped, and the two ends of the limiting steel cable are respectively inserted into the sealing ring.

[0014] The above technical solution incorporates a limiting steel cable insertion structure that enhances the stability of the internal structure of the protective tube, preventing displacement of the insulating arc plate when subjected to external impact or vibration, thus ensuring the overall structural strength.

[0015] Preferably, the positioning groove inside the insulating inner tube is spiral-shaped, and the insulating inner tube is placed in the same axial direction as the insulating ring.

[0016] Using the above technical solution, the spiral positioning groove inside the insulating inner tube can accurately fix the cable, prevent the cable from moving inside the tube, and avoid wear caused by cable shaking.

[0017] Preferably, the insulating ring is fitted inside the sealing ring, and a rubber ring is provided at the connection between the insulating ring and the sealing ring.

[0018] By adopting the above technical solution, the insulating ring is sleeved inside the sealing ring and a rubber ring is set at the connection, which enhances the sealing performance of the end of the protective tube, effectively preventing moisture and corrosive substances from entering and protecting the insulation performance.

[0019] Preferably, the sealing ring is penetrated by one end of the protective sleeve, and the diameter of the sealing ring is larger than the diameter of the insulating ring.

[0020] By adopting the above technical solution, the sealing ring and the insulating ring are fitted together to form a good sealing structure at the end of the protective tube, which can effectively block adverse factors in the external environment.

[0021] Compared with the prior art, the beneficial effects of this utility model are: This high-strength insulated PE cable protection pipe:

[0022] 1. The two insulating arc-shaped plates and the arc-shaped reinforcing bracket inside the protective sleeve form a ring structure, and the reinforcing bracket is equidistantly distributed between the insulating arc-shaped plates, forming a stable mechanical support system. When the protective sleeve is subjected to external pressure, the reinforcing bracket and the insulating arc-shaped plates work together to disperse the pressure. In addition, the limiting steel cable passes through the insulating arc-shaped plate, with its two ends in an L shape and inserted into the sealing ring, further enhancing the overall structural stability of the protective sleeve. When subjected to impact or vibration, the limiting steel cable restricts the displacement of the insulating arc-shaped plate, prevents the components from loosening, ensures that the protective sleeve can still maintain high strength under complex working conditions, extend its service life, improve its compressive strength, effectively protect the cable from mechanical damage, and ensure the reliability of power transmission.

[0023] 2. The rubber ring on the outer wall of the protective sleeve can effectively fill gaps and enhance sealing when connected with other pipes or components, preventing external moisture, dust, corrosive gases, etc. from entering the interior of the protective sleeve. As the sealing ring is fitted over the insulating ring, a tight sealing structure is formed at the end of the protective sleeve. At the same time, the rubber ring set at the connection between the insulating ring and the sealing ring further improves the sealing effect, prevents moisture from seeping in and affecting the insulation performance, avoids cable failure due to moisture, and ensures the safe and stable operation of the cable in harsh environments such as humid and rainy conditions.

[0024] 3. The insulating arc plate, insulating inner tube, and insulating ring in this protective tube are all made of insulating material, forming a multi-layered insulating protection system. As the cable is inserted into the insulating inner tube and insulating ring, the protective structure is realized. The insulating ring is inserted into one end of the protective sleeve and abuts against the insulating inner tube, which enhances the end insulation effect, effectively isolates the cable from the outside world, and reduces the risk of leakage. In addition, the spiral positioning groove in the insulating inner tube is adapted to the surface structure of the cable, which can accurately fix the position of the cable and prevent the cable from shifting or shaking due to gravity or external forces in the protective tube, avoid cable wear, and ensure the integrity of the cable insulation layer.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Please refer to Figures 1-6. This utility model provides a technical solution: a high-strength insulated PE cable protection pipe, including a protective sleeve 1, a rubber ring 2, an insulating arc plate 3, a reinforcing bracket 4, a limiting steel cable 5, an insulating inner tube 6, a positioning groove 7, an insulating ring 8, and a sealing ring 9.

[0034] Among them, the protective sleeve 1 is the main structure of the cable protection pipe. The protective sleeve 1 is a cylindrical structure and the cable runs through the inside of the protective sleeve 1.

[0035] Rubber rings 2 are equidistantly arranged on the outer wall of the protective sleeve 1, and two insulating arc plates 3 are fitted inside the protective sleeve 1. A reinforcing bracket 4 is arranged between the two insulating arc plates 3, and the reinforcing bracket 4 is arc-shaped. The insulating arc plates 3 and the reinforcing bracket 4 are fitted inside the protective sleeve 1, and the two insulating arc plates 3 and the reinforcing bracket 4 form a ring structure. The reinforcing bracket 4 is equidistantly arranged between the two insulating arc plates 3, and an insulating inner tube 6 is fitted inside the insulating arc plates 3 and the reinforcing bracket 4. The positioning groove 7 inside the insulating inner tube 6 is spiral, and the insulating inner tube 6 is placed in the same axial direction as the insulating ring 8.

[0036] As shown in Figures 1-6 of the accompanying drawings, rubber rings 2 are equidistantly arranged on the outer wall of the protective sleeve 1. This enhances the sealing performance when connected to other pipes or components, preventing the intrusion of external moisture, corrosive substances, etc. Inside the protective sleeve 1, two insulating arc-shaped plates 3 and an arc-shaped reinforcing bracket 4 form a ring structure. Since the reinforcing bracket 4 is equidistantly arranged between the two insulating arc-shaped plates 3, it facilitates the dispersion of impact force. When the protective sleeve is subjected to external radial pressure, the reinforcing bracket 4, with its arc-shaped structure and its own strength, disperses the pressure and, together with the insulating arc-shaped plates 3, resists external force, preventing the protective sleeve 1 from deforming due to pressure, ensuring that the cable space is not squeezed, and maintaining the normal operation of the cable. The spiral positioning groove 7 on the surface of the insulating inner tube 6 can cooperate with the corresponding structure on the cable to achieve precise positioning of the cable inside the protective sleeve, facilitating installation and laying. At the same time, the components are connected by nesting, abutting, etc., such as the insulating arc-shaped plate 3 and the reinforcing bracket 4 nesting the insulating inner tube 6, and the insulating ring 8 abutting against the insulating inner tube 6, ensuring the overall structure is stable.

[0037] The insulating arc plate 3 is penetrated by a limiting steel cable 5, and each end of the limiting steel cable 5 passes through an insulating ring 8. The two ends of the limiting steel cable 5 are L-shaped and are inserted into sealing rings 9. The insulating ring 8 is inserted into one end of the protective sleeve 1, and the insulating ring 8 is covered with a sealing ring 9. The insulating ring 8 abuts against the insulating inner tube 6, and the surface of the insulating inner tube 6 is provided with a positioning groove 7. The insulating ring 8 is fitted inside the sealing ring 9, and a rubber ring is provided at the connection between the insulating ring 8 and the sealing ring 9. The sealing ring 9 is penetrated by one end of the protective sleeve 1, and the diameter of the sealing ring 9 is larger than the diameter of the insulating ring 8.

[0038] As shown in Figures 1-6 of the accompanying drawings, the limiting steel cable 5 inside the insulating arc plate 3 can limit the displacement of the insulating arc plate 3, enhance the integrity and stability of the entire structure, and prevent the relative position of the insulating arc plate 3 and the reinforcing bracket 4 from changing when subjected to impact or vibration, further improving the mechanical strength of the protective tube and ensuring mechanical protection of the cable. Moreover, the insulating arc plate 3, the insulating inner tube 6 and the insulating ring 8 are all made of insulating materials. By fitting them together, as shown in Figures 1-4, the insulating inner tube 6 wraps around the cable, providing the first layer of insulation protection. The insulating arc plate 3 and the insulating ring 8 on the outer layer of the insulating inner tube 6 together form a multi-layer insulation barrier, blocking current leakage and improving insulation performance.

[0039] The insulating ring 8 is inserted into one end of the protective sleeve 1, and the sealing ring 9 is placed on the outside. The insulating ring 8 abuts against the inner insulating tube 6. Since the insulating ring 8 plays the role of end insulation, the sealing ring 9 not only prevents moisture and impurities from entering and affecting the insulation, but also assists the insulating ring 8 in enhancing the end insulation effect and preventing leakage. The sealing ring 9 is penetrated by one end of the protective sleeve 1 and its diameter is larger than that of the insulating ring 8, further sealing the end of the protective tube, preventing external substances from entering the interior and affecting the cable operating environment, and maintaining the stability of insulation and mechanical properties.

[0040] Working Principle: When using this high-strength insulated PE cable protection pipe, the reinforcing bracket 4 between the two insulating arc-shaped plates 3 provides stable support. When the protection pipe is subjected to external radial pressure, the reinforcing bracket 4, with its arc-shaped structure and inherent strength, disperses the pressure and, together with the insulating arc-shaped plates 3, resists external forces, preventing the protection sleeve 1 from deforming due to pressure, ensuring that the cable space is not squeezed, and maintaining the normal operation of the cable. The limiting steel cable 5, which runs through the insulating arc-shaped plates 3, restricts the displacement of the insulating arc-shaped plates 3, enhancing the integrity and stability of the entire structure. This prevents the insulation from arcing when subjected to impact or vibration. The relative positions of the shaped plate 3 and the reinforcing bracket 4 change. When in use, the insulating inner tube 6 wraps around the cable, providing the first layer of insulation protection. The surface of the insulating inner tube 6 has a spiral positioning groove 7, which can prevent the cable from sliding inside the tube. The insulating arc plate 3 and the insulating ring 8 on the outer layer of the insulating inner tube 6 together form a multi-layer insulation barrier to block current leakage and improve insulation performance. The insulating ring 8 is inserted into one end of the protective sleeve 1, and the insulating ring 8 plays the role of end insulation. The sealing ring 9 not only prevents moisture and impurities from entering and affecting the insulation, but also assists the insulating ring 8 in enhancing the end insulation effect, preventing leakage, and increasing the overall practicality.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
