Technical Field

[0001] The utility model relates to the technical field of HDPE winding reinforced pipes, and more specifically, to a HDPE winding structure wall reinforced pipe. Background Art

[0002] HDPE spiral reinforced pipe is a pipe product made of high-density polyethylene (HDPE) as the main raw material. It has excellent wear resistance, corrosion resistance and pressure resistance. It is suitable for pipeline projects of various conveying media, including water, sewage, chemicals, etc. HDPE spiral reinforced pipe usually adopts a special production process to improve the strength and pressure resistance of the pipe by winding reinforcing materials (usually glass fiber or carbon fiber) on the outside of the HDPE pipe. This design enables the pipe to withstand higher pressure and temperature and has a longer service life. It is a pipe product with superior performance, reliability and durability.

[0003] However, due to the limitation of material properties, at present, the outer wall and the inner wall of the wound corrugated pipe are made of PE material, and the price of PE material is relatively high. Although the wound corrugated pipe made of all PE material can obtain good performance, the production cost is relatively high. Moreover, in some occasions requiring high strength, the all-PE pipe cannot meet the high-strength requirements and is easily deformed by external force, or even ruptured, resulting in a shortened service life of the wound flat wall pipe. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, an embodiment of the utility model provides a HDPE wound structural wall reinforced pipe to solve the problem that in certain occasions where high strength is required, the existing full PE pipe cannot meet the high strength requirements, is easily deformed by external forces, and even ruptures, resulting in a shortened service life of the wound flat wall pipe.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions: a HDPE wound structural wall reinforced pipe, comprising a pipe body, the outer surface of the pipe body is fixedly connected with reinforcing ribs, both ends of the pipe body are fixedly connected with connecting pipe openings, the pipe body comprises an inner pipe, the inner wall of the inner pipe is bonded with a carbon fiber layer, the outer surface of the inner pipe is fixedly sleeved with a plurality of fixing rings, the outer surface of the fixing ring is bonded with an outer pipe, the outer surface of the outer pipe is bonded with an HDPE outer layer, and the reinforcing ribs are spirally fixedly connected to the outer surface of the HDPE outer layer.

[0006] Among them, the inner and outer sides of the multiple fixing rings are fixedly connected with wire meshes, and air bags are embedded and installed between the inner and outer wire meshes. The fixing rings are fixedly sleeved on the outer surface of the inner tube, and the wire meshes on the inner and outer sides of the fixing rings are respectively bonded to the outer surface of the inner tube and the inner wall of the outer tube.

[0007] Wherein, the outer surface of the reinforcing rib is provided with a protective layer, and the protective layer is a UPVC layer.

[0008] Among them, the reinforcing ribs include a reinforcing tube, which is wrapped and connected to the outer surface of the tube body, and both ends of the inside of the reinforcing tube are fixedly connected with trapezoidal ribs, and the reinforcing tube and the trapezoidal ribs form a mutually staggered trapezoid. The top of the reinforcing tube is fixedly connected with an arc-shaped wear-resistant block, and the material of the arc-shaped wear-resistant block is ceramic.

[0009] Among them, a support frame is fixedly connected between the reinforcement pipes, and both ends of the bottom of the support frame are fixedly connected with a fixing frame, and the support frame is fixedly connected to the outer surface of the pipe body through the fixing frame.

[0010] Among them, a plurality of arc tubes are fixedly connected to the outer surface of the tube body, the arc tubes and the reinforcement tubes are staggered and distributed with each other, and the arc tubes are made of elastic material.

[0011] Technical effects and advantages of the utility model:

[0012] In the above scheme, the steel meshes inside and outside the fixing ring are respectively bonded to the outer surface of the inner tube and the inner wall of the outer tube, and the airbag is used to increase the toughness of the overall HDPE winding reinforced tube. When the outer surface of the HDPE winding reinforced tube is impacted, the airbag is deformed to absorb the force received, thereby improving the compression resistance of the HDPE winding reinforced tube and preventing the inner tube and the carbon fiber layer from being ruptured due to impact.

[0013] The arc-shaped wear-resistant block is set on the outer surface of the reinforced pipe. When the HDPE wrapped reinforced pipe is pulled and moved, the arc-shaped wear-resistant block rubs against the ground or wall, thereby preventing the surface of the HDPE wrapped reinforced pipe from being worn during movement;

[0014] The support frame and the fixing frame are used to increase the overall axial strength of the HDPE winding reinforced pipe, thereby preventing the HDPE winding reinforced pipe from being excessively bent and causing wear of the HDPE winding reinforced pipe, and at the same time, enhancing the strength of the HDPE winding reinforced pipe;

[0015] By arranging arc pipes between a plurality of reinforcement pipes, the flexibility of the HDPE winding reinforced pipe itself is enhanced, thereby improving the bending resistance of the HDPE winding reinforced pipe. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] In order to make the technical problems to be solved, technical solutions and advantages of the present invention more clear, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0023] First embodiment

[0024] As attached Figure 1 To Attachment Figure 3 The embodiment of the utility model provides a HDPE winding structure wall reinforced pipe, including a pipe body 1, the outer surface of the pipe body 1 is fixedly connected with a reinforcing rib 3, both ends of the pipe body 1 are fixedly connected with a connecting pipe mouth 2, the pipe body 1 includes an inner pipe 11, the inner wall of the inner pipe 11 is bonded with a carbon fiber layer 12, the outer surface of the inner pipe 11 is fixedly sleeved with a plurality of fixing rings 13, the outer surface of the fixing ring 13 is bonded with an outer pipe 14, the outer surface of the outer pipe 14 is bonded with an HDPE outer layer 15, the reinforcing rib 3 is spirally fixedly connected to the outer surface of the HDPE outer layer 15, and the material of the carbon fiber layer 12 is carbon fiber material to increase the firmness of the inner pipe 11 and the carbon fiber layer 12, avoid impurities contained in the conveying medium, and avoid the impurities from wearing the inner wall of the carbon fiber layer 12, thereby affecting the service life of the HDPE winding reinforced pipe.

[0025] Among them, the inner and outer sides of the multiple fixing rings 13 are fixedly connected with steel meshes 16, and an airbag 17 is embedded and installed between the inner and outer steel meshes 16. The fixing ring 13 is fixedly sleeved on the outer surface of the inner tube 11, and the steel meshes 16 on the inner and outer sides of the fixing ring 13 are respectively bonded to the outer surface of the inner tube 11 and the inner wall of the outer tube 14. The airbag 17 is used to increase the toughness of the overall HDPE wrapped reinforced tube. When the outer surface of the HDPE wrapped reinforced tube is impacted, the deformation of the airbag 17 absorbs the force received, thereby improving the compressive resistance of the HDPE wrapped reinforced tube and preventing the inner tube 11 and the carbon fiber layer 12 from being ruptured due to impact.

[0026] The outer surface of the reinforcing rib 3 is provided with a protective layer, which is a UPVC layer.

[0027] Second embodiment

[0028] Compared with the first embodiment, the second embodiment is further optimized: by changing the structure of the reinforcing rib 3, the reinforcing rib 3 is made stronger, and the arc-shaped wear-resistant blocks 303 on the surface are used to improve the overall wear resistance of the HDPE wrapped reinforced pipe.

[0029] As attached Figure 4 As shown, the reinforcing rib 3 includes a reinforcing tube 301, which is wrapped around and connected to the outer surface of the tube body 1, and both ends of the interior of the reinforcing tube 301 are fixedly connected with trapezoidal ribs 302, forming an interlaced trapezoid between the reinforcing tube 301 and the trapezoidal ribs 302, and the top of the reinforcing tube 301 is fixedly connected with an arc-shaped wear-resistant block 303, and the material of the arc-shaped wear-resistant block 303 is ceramic.

[0030] Since ceramics have strong wear resistance, long service life, and a wide range of heat resistance, they can be used in various fields. Therefore, the arc-shaped wear-resistant block 303 is set on the outer surface of the reinforcement pipe 301. When the HDPE wrapped reinforced pipe is pulled and moved, the arc-shaped wear-resistant block 303 rubs against the ground or wall, thereby avoiding surface wear of the HDPE wrapped reinforced pipe during movement.

[0031] As attached Figure 4 As shown, a support frame 304 is fixedly connected between the reinforcement pipes 301 , and both ends of the bottom of the support frame 304 are fixedly connected with a fixing frame 305 . The support frame 304 is fixedly connected to the outer surface of the pipe body 1 through the fixing frame 305 .

[0032] The support frame 304 and the fixing frame 305 increase the overall axial strength of the HDPE wrapped reinforced pipe, prevent the HDPE wrapped reinforced pipe from being excessively bent, which may cause wear of the HDPE wrapped reinforced pipe, and at the same time, enhance the strength of the HDPE wrapped reinforced pipe.

[0035] The working process of the utility model is as follows:

[0036] The steel meshes 16 on the inner and outer sides of the fixing ring 13 are respectively bonded to the outer surface of the inner tube 11 and the inner wall of the outer tube 14. The airbag 17 is used to increase the toughness of the overall HDPE winding reinforced tube. When the outer surface of the HDPE winding reinforced tube is impacted, the airbag 17 is deformed to absorb the force received, thereby improving the compression resistance of the HDPE winding reinforced tube and preventing the inner tube 11 and the carbon fiber layer 12 from being ruptured due to impact.

[0037] The arc-shaped wear-resistant block 303 is arranged on the outer surface of the reinforcement pipe 301. When the HDPE wrapped reinforced pipe is pulled and moved, the arc-shaped wear-resistant block 303 rubs against the ground or wall, thereby preventing the surface of the HDPE wrapped reinforced pipe from being worn during the movement;

[0038] The support frame 304 and the fixing frame 305 increase the overall axial strength of the HDPE winding reinforced pipe, prevent the HDPE winding reinforced pipe from being excessively bent, resulting in wear of the HDPE winding reinforced pipe, and at the same time, enhance the strength of the HDPE winding reinforced pipe;

[0039] By arranging the arc tube 306 between the plurality of reinforcement tubes 301 , the flexibility of the HDPE winding reinforced tube itself is enhanced, thereby improving the bending resistance of the HDPE winding reinforced tube.
