[0030] In this embodiment, by designing a pipeline body 1, the pipeline body 1 can adopt a composite material, such as a composite structure of PE and glass fiber, aluminum, carbon fiber, which can further improve the compressive strength, high temperature resistance, shock resistance and the like of the pipeline. Therefore, the pipeline body 1 adopts a composite material, which not only improves the physical properties of the PE pipe, but also makes it perform better in specific environmental conditions (such as high temperature and high pressure), and the pipeline body 1 can be made by extrusion molding process, so that different materials are used at different levels to manufacture a PE pipe with higher strength and higher pressure resistance. And there are eight fixing rods 2 arranged in a ring array on the outer wall of the pipeline body 1, four fixing rings 3 are fixedly connected to the outer wall of the eight fixing rods 2, and a plurality of buffer blocks 6 are arranged in a ring array on the outer wall of the pipeline body 1 between the four fixing rings 3. A second connecting groove 7 is formed in the lower end of the buffer block 6, the second connecting groove 7 is connected with the fixing rod 2 in correspondence, and a plurality of supporting blocks 5 are arranged in a ring array on the outer wall of the fixing ring 3 on both sides, the other end of the supporting block 5 is fixedly connected with the outer wall of the pipeline body 1, and the supporting block 5 has an inclination and is connected with the fixing ring 3 to form a triangle, and the triangle has stability, which ensures that the fixing ring 3 will not be offset when subjected to extrusion, thereby causing damage to the internal support structure. A plurality of buffer blocks 6 are provided to completely wrap the pipeline body 1, and are made of soft material, which has a buffering effect, avoiding the pipeline body 1 from being directly affected by impact vibration, thereby causing the pipeline body 1 to be broken. Therefore, the fixing rod 2, the fixing ring 3 and the buffer block 6 can further play a role of high strength and high pressure resistance for the pipeline body 1.

[0031] Embodiment 2

[0032] As shown in Figures 1-2 and Figures 4-5 , a third connecting groove 8 is formed in the outer wall of the upper end of the buffer block 6, an enhanced layer 9 is connected to the outer wall of the buffer block 6, a reinforcing member 10 is fixedly connected to the inner wall of the enhanced layer 9, eight reinforcing members 10 are arranged in a ring array on the inner wall of the enhanced layer 9, and the third connecting groove 8 is connected with the outer wall of the buffer block 6 on one side of the eight reinforcing members 10. An outer layer 11 is fixedly connected to the outer wall of the enhanced layer 9, the inner part of the outer layer 11 forms a triangular pattern, and a plurality of uniform distribution are arranged on the outer layer 11.

[0033] In this embodiment, the third connecting groove 8 is arranged on the outer wall of the buffer block 6, and the reinforcing layer 9 is fixedly connected to one side of the outer wall of the buffer block 6. Eight reinforcing members 10 are arranged in an annular array on the inner wall of the reinforcing layer 9. The eight reinforcing members 10 are connected to the third connecting groove 8 arranged on the outer wall of the buffer block 6. The reinforcing member 10 adopts a triangular structure, and the tip thereof faces one side of the pipeline body 1. Therefore, when the reinforcing layer 9 is subjected to external action, the force is transmitted inward. At this time, the contact surface between the reinforcing member 10 and the first connecting groove 4 is triangular, and the surfaces on both sides of the first connecting groove 4 will exert an external force, thereby being able to slow down the impact force of the external world. The outer wall of the reinforcing layer 9 is provided with an outer layer 11. The inner part of the outer layer 11 is triangular in structure and is arranged in multiple uniform actions on the outer layer 11. Therefore, the outer layer 11 further plays a buffering role of the force, and is made of high-temperature-resistant polyethylene. Carbon black is added to the outer wall of the outer layer 11 to enhance the anti-ultraviolet ability. The carbon black can effectively absorb ultraviolet rays, prevent the degradation of the pipeline surface due to ultraviolet irradiation, and make the pipeline have a certain wear-resistant effect.

[0034] Working principle:

[0035] As Figures 1-5As shown, the working principle of the device is based on the multi-layer composite material structure of the pipeline body 1, combined with the fixed assembly and the buffer device, aiming to provide high strength, high pressure resistance, high temperature resistance, shock resistance and other performances, adapting to complex use environment. First of all, the pipeline body 1 adopts a composite material structure, such as the combination of polyethylene (PE) and glass fiber, aluminum and carbon fiber, which significantly improves the physical performance of the pipeline. The combination of these materials enables the pipeline to maintain excellent performance in the face of complex environments such as high temperature, high pressure and vibration. The manufacturing process of the pipeline is extrusion molding, through which different materials can be used at different levels to improve the strength and pressure resistance of the pipeline. The outer wall of the pipeline body 1 is evenly arranged with eight fixed rods 2, which are connected with four fixed rings 3 to form a stable structure. Between each fixed ring 3, there are a plurality of buffer blocks 6, which are made of soft material and have a second connecting groove 7, which is connected with the fixed rod 2 through the groove. The role of the buffer block 6 is to reduce the direct pressure on the pipeline when it is impacted or vibrated, thereby effectively preventing the pipeline body 1 from being broken due to vibration or external force. In order to enhance the stability of the pipeline, a plurality of support blocks 5 are arranged on both sides of the fixed ring 3, the other end of which is fixedly connected with the outer wall of the pipeline body 1 and presents a certain inclination angle, forming a stable triangular structure with the fixed ring 3. The stability of this triangular structure can prevent the fixed ring 3 from being offset when subjected to external pressure, thereby ensuring that the support structure is not damaged and maintaining the overall stability of the pipeline. In addition, a third connecting groove 8 is provided on the outer wall of the buffer block 6, and an enhanced layer 9 is fixedly connected on one side of its outer wall. The enhanced layer 9 is internally provided with eight triangular reinforcing members 10, which are connected with the third connecting groove 8, with the pointed ends facing the pipeline body 1. The role of the enhanced layer 9 is to transfer the external impact force to the buffer block 6, thereby reducing the impact of external impact on the pipeline and further enhancing the durability of the pipeline. The outer wall of the enhanced layer 9 is provided with an outer layer 11, which is made of high-temperature-resistant polyethylene material and has added carbon black on its surface to enhance its ultraviolet resistance. Carbon black can effectively absorb ultraviolet rays, preventing the surface of the pipeline from degrading due to ultraviolet radiation, while also imparting wear resistance to the pipeline, further improving its service life. In summary, the working principle of the pipeline body 1 is achieved through the selection of composite materials, the coordinated action of the fixed ring 3, the support block 5, the buffer block 6 and the enhanced layer 9 and other components, ensuring the excellent performance of the pipeline in high strength, high pressure, high temperature and vibration environments. Through the design of multiple buffers and stable structures, the pipeline can effectively withstand external impact, avoid damage and prolong its service life.
