[0002] PE communication pipes, also known as HDPE communication pipes, are widely used in the construction of various communication networks, including urban communication networks, rural communication networks, industrial communication networks, etc. In urban communication networks, PE communication pipes are mainly used to protect underground communication lines such as urban telecommunication optical cables, cable television lines, and traffic signal lines; while in rural communication networks and industrial communication networks, PE communication pipes are mainly used to protect communication lines in rural and industrial areas. However, due to the characteristics of PE pipes during use, they will be affected when encountering humid or corrosive environments. Therefore, a reinforced protective PE communication pipe is needed.

[0003] The application number retrieved is: CN202111225667.8, a multi-layer protective PE communication pipe. The multi-layer protective PE communication pipe has the advantage of being able to provide protection. The PE communication pipe will not be corroded or melted by high temperature when used by the user, thereby ensuring normal use by the user without the need for frequent maintenance by the user.

[0004] However, the existing PE pipes still have certain defects in actual use: when the PE pipes are used and transported, when the PE pipes come into contact with a humid environment, the use of the PE pipes will be affected, and when the PE pipes are placed in an extremely corrosive environment, the PE pipes will be corroded, thereby damaging the internal structure of the PE pipes. For this reason, we propose a reinforced protection PE communication pipe. Utility Model Content

[0005] In order to make up for the above deficiencies, the utility model provides a reinforced protection type PE communication pipe, which aims to improve the problem that when the PE pipe is used and transported, the PE pipe comes into contact with a humid environment, which affects the use of the PE pipe, and when the PE pipe is placed in an extremely corrosive environment, it will cause the PE pipe to be corroded, thereby causing damage to the internal structure of the PE pipe.

[0006] The utility model realizes a reinforced protection type PE communication pipe through the following technical scheme, including a pipe body and a filling reinforcement layer, the pipe body includes an outer pipe body, a filling reinforcement layer and an inner pipe body, and the filling reinforcement layer is installed on both sides of the inner wall of the outer pipe body, and the inner pipe body is arranged on the side of the filling reinforcement layer away from the outer pipe body, and the outer surface of the outer pipe body is provided with a retaining ring, and the centers of the two groups of the retaining rings are provided with wear-resistant protrusions.

[0007] Furthermore, the filling reinforcement layer includes a rubber filling layer, a metal wire, an insulating layer, an outer anti-bending layer and an inner anti-bending layer, and the metal wire is installed at the center of the rubber filling layer, and the insulating layer is installed on the outer surface of the rubber filling layer, and the outer anti-bending layer is arranged on the side of the insulating layer away from the rubber filling layer, and the inner anti-bending layer is arranged on the side of the rubber filling layer away from the insulating layer.

[0008] Furthermore, the outer tube body includes an inner wear-resistant layer, a carbon fiber wrapped skeleton and an outer wear-resistant layer, and the inner wear-resistant layer is provided with a carbon fiber wrapped skeleton on the side away from the filling reinforcement layer, and the carbon fiber wrapped skeleton is provided with an outer wear-resistant layer on the side away from the inner wear-resistant layer.

[0009] Furthermore, the inner tube body includes a first shielding layer, an anti-oxidation layer and a second shielding layer, and the anti-oxidation layer is arranged on a side of the first shielding layer away from the filling reinforcement layer, and the second shielding layer is arranged on a side of the anti-oxidation layer away from the first shielding layer.

[0010] Furthermore, the distance between the two groups of retaining rings is the same, the distance between the wear-resistant protrusions at the centers of the two groups of retaining rings is the same, and the number of the wear-resistant protrusions at the centers of the two groups of retaining rings is the same.

[0012] The utility model provides a reinforced protection type PE communication pipe, which has the following beneficial effects:

[0013] The pipeline body is divided into an outer pipe body, a filling reinforcement layer and an inner pipe body. The rubber filling layer in the filling reinforcement layer cooperates with the metal wire to provide the pipeline body with impact resistance. Due to the inherent properties of the rubber, the internal structure of the pipeline body can be provided with thermal insulation properties, so that when it is in a low temperature environment, the temperature change inside the inner pipe body can be weakened. At the same time, due to the metal properties of the insulating layer, when the pipeline itself is in a humid environment, moisture cannot penetrate into the interior of the pipeline. Since the main body is composed of a multi-layer structure of a first shielding layer, an anti-oxidation layer and a second shielding layer, when the inner pipe body comes into contact with corrosive substances, the metal properties of the first shielding layer and the second shielding layer themselves will slow down the time for corrosive corrosion to penetrate inward, thereby facilitating processing and maintenance.

[0023] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0024] like Figure 1 - Figure 7 As shown, a reinforced protection type PE communication pipe includes a pipe body 1 and a filling reinforcement layer 5. The pipe body 1 includes an outer pipe body 4, a filling reinforcement layer 5 and an inner pipe body 6. The filling reinforcement layer 5 is installed on both sides of the inner wall of the outer pipe body 4, and the inner pipe body 6 is arranged on the side of the filling reinforcement layer 5 away from the outer pipe body 4. The outer surface of the outer pipe body 4 is provided with a retaining ring 2, and the center of the two sets of retaining rings 2 is provided with a wear-resistant protrusion 3. The design of the pipe body 1 cleverly combines the outer pipe body 4, the filling reinforcement layer 5 and the inner pipe body 6 to form a solid protective structure. The outer pipe body 4 is the outer layer of the pipe and is subjected to the influence of the external environment, such as soil pressure, temperature changes, etc. The filling reinforcement layer 5 is located between the outer pipe body 4 and the inner pipe body 6. Its main function is to enhance the pressure resistance and stability of the pipe. The filling reinforcement layer 5 obtains elasticity and strength through the rubber filling layer 7 and the metal wire 8 to cope with various external pressures. The retaining ring 2 is evenly distributed on the outer surface of the outer pipe body 4, which plays a role in fixing and protecting the pipe. The retaining ring 2 can reduce the friction damage of the pipeline during transportation and installation, and the wear-resistant protrusion 3 is located at the center of the two sets of retaining rings 2. Their presence further enhances the wear resistance of the pipeline. The wear-resistant protrusion 3 effectively resists external wear during the use of the pipeline.

[0025] The filling reinforcement layer 5 includes a rubber filling layer 7, a metal wire 8, an insulating layer 9, an outer anti-bending layer 10 and an inner anti-bending layer 11, and the metal wire 8 is installed at the center of the rubber filling layer 7, and the insulating layer 9 is installed on the outer surface of the rubber filling layer 7, and the outer anti-bending layer 10 is arranged on the side of the insulating layer 9 away from the rubber filling layer 7, and the inner anti-bending layer 11 is arranged on the side of the rubber filling layer 7 away from the insulating layer 9. The structure of the rubber filling layer 7 is that the filling reinforcement layer 5 provides softness and elasticity to the pipeline body 1, and is also used to absorb and disperse external impact force when the pipeline body 1 collides and is squeezed, so as to protect the internal structure and components. The equidistant placement of the metal wire 8 is used to enhance the strength and stability of the filling reinforcement layer 5, so that it has better tensile and compressive properties. The setting of the insulating layer 9 is to ensure the electrical safety of the pipeline body 1 itself. It can effectively prevent the current from passing through the filling reinforcement layer 5, thereby avoiding possible electrical failures and dangers. At the same time, the insulating layer 9 itself is a metal structure. According to the properties of its own metal structure, the insulating layer 9 has good wear resistance and chemical corrosion resistance, which can extend the service life of the filling and reinforcing layer 5. The outer anti-bending layer 10 and the inner anti-bending layer 11 are used to improve the anti-bending ability of the filling and reinforcing layer 5. When the pipeline body 1 is affected by external force and bends, the outer anti-bending layer 10 and the inner anti-bending layer 11 can effectively resist the external bending force through their own structure during the bending process, and maintain the shape and structural stability of the filling and reinforcing layer 5.

[0026] The outer tube body 4 includes an inner wear-resistant layer 12, a carbon fiber wrapped skeleton 13 and an outer wear-resistant layer 14, and the inner wear-resistant layer 12 is provided with a carbon fiber wrapped skeleton 13 on the side away from the filling reinforcement layer 5, and the outer wear-resistant layer 14 is provided on the side away from the inner wear-resistant layer 12 of the carbon fiber wrapped skeleton 13, and the inner wear-resistant layer 12 is made of high-performance materials, so that when friction occurs, the damage caused by friction can be reduced, and the pipeline is protected from medium erosion. The carbon fiber wrapped skeleton 13 provides tensile strength and rigidity to the pipeline body 1 through its own tensile strength and rigidity, so as to maintain the overall structural stability of the pipeline body 1, and the high modulus and high strength of the carbon fiber enable the skeleton to effectively disperse and resist external forces when subjected to external forces, protecting the pipeline from damage, and the outer wear-resistant layer 14 further enhances the wear resistance and durability of the pipeline. The wear-resistant structure used for the external wear resistance can maintain stable performance for a long time in a harsh working environment, and can maintain the service life of the pipeline body 1 during the use of the pipeline body 1.

[0027] The inner tube body 6 includes a first shielding layer 15, an anti-oxidation layer 16, and a second shielding layer 17. The first shielding layer 15 is provided with an anti-oxidation layer 16 on the side away from the filling reinforcement layer 5, and the second shielding layer 17 is provided on the side away from the first shielding layer 15. The first shielding layer 15 is mainly used to block the interference of electromagnetic waves to ensure that the data transmission and signal processing inside the inner tube body 6 are not affected by the external electromagnetic environment. This shielding layer is the first layer structure to protect the inner tube body 6 from electromagnetic interference, and the second shielding layer 17 further enhances the electromagnetic shielding effect. It works together with the first shielding layer 15 to form a solid electromagnetic barrier.

[0028] The anti-oxidation layer 16 is mainly used to prevent the inner tube body 6 from being affected by oxidation during long-term use, thereby maintaining its performance and life. The provision of the anti-oxidation layer 16 greatly improves the durability of the inner tube body 6, allowing it to work stably in various complex environments.

[0029] The distance between the two groups of retaining rings 2 is the same, the distance between the wear-resistant protrusions 3 at the centers of the two groups of retaining rings 2 is the same, and the number of the wear-resistant protrusions 3 at the centers of the two groups of retaining rings 2 is the same.

[0030] The distances between the two groups of metal wires 8 are the same, and the outer tube body 4, the filling reinforcement layer 5 and the inner tube body 6 are bonded by resin.

[0031] In summary, the utility model comprises a pipe body 1 and a filling reinforcement layer 5, wherein the pipe body 1 is divided into an outer pipe body 4, a filling reinforcement layer 5 and an inner pipe body 6, wherein the inner wall of the inner wear-resistant layer 12 of the outer pipe body 4 is used to connect with the filling reinforcement layer 5 through resin, and the outer surface of the inner wear-resistant layer 12 is bonded with a carbon fiber wire wrapped skeleton 13, and when the inner wall of the outer wear-resistant layer 14 is bonded to the carbon fiber wire wrapped skeleton 13, when the pipe body 1 is bent, the carbon fiber wire wrapped skeleton 13 located at the center of the inner wear-resistant layer 12 and the outer wear-resistant layer 14 will bend along with the pipe body 1, and since the carbon fiber wire wrapped skeleton 13 itself can effectively disperse and resist external forces, it can The wear resistance of the pipeline body 1 itself is improved, and the retaining ring 2 and the wear-resistant protrusion 3 arranged on the outer surface of the outer wear-resistant layer 14 of the outer pipe body 4 can enable the retaining ring 2 to reduce the friction damage of the pipeline during transportation and installation when the pipeline body 1 is in the external environment. The wear-resistant protrusion 3 is located at the center of the two groups of retaining rings 2. Their existence further enhances the wear resistance of the pipeline. The rubber filling layer 7 and the metal wire 8 in the filling reinforcement layer 5, together with the outer anti-bending layer 10 and the inner anti-bending layer 11, can improve the bending ability of the pipeline body 1. At this time, the inner pipe body 6 of the pipeline body 1 can provide the pipeline body 1 with electromagnetic shielding and anti-oxidation capabilities, so that the pipeline can be used in complex environments.
