Description

Technical Field

[0001] The utility model relates to the technical field of plastic winding pipes, in particular to a double-high-fiber continuous co-extrusion reinforced winding pipe. Background Art

[0002] Spiral pipe is a tubular structure made by spirally wrapping an extruded plastic strip around a rolling device and bonding the strips together. Its base material is mostly PE, PP, or HDPE. It boasts remarkable technical characteristics and a wide range of applications. Its smooth inner wall makes it corrosion-resistant, lightweight, easy to install, has a high flow rate, and a long service life. At the same weight, it offers higher ring stiffness and greater impact resistance, making it an environmentally friendly alternative to pipes made from high-energy-consuming materials (cement, cast iron, fiberglass, ceramic, etc.). Consequently, various types and structures of spiral pipe have emerged on the market to address diverse operating environments and conditions.

[0003] For example, the prior art discloses a porous, high-rib reinforced polyethylene spiral wound pipe (authorization publication number CN220228154U). This pipe is often used as a drainage pipe buried deep underground, requiring it to withstand significant soil pressure and high hoop stiffness. Therefore, the internal support frame of the spiral wound pipe is designed in a Y-shape. The two prongs of the Y-shape and the vertical section form three support points, which together withstand radial and axial extrusion forces. Another example is a FRPE-reinforced composite spiral wound pipe (authorization publication number CN208670311U). This pipe utilizes a composite structure, with an internal PP circumferentially enclosed tube and an external PE circumferentially enclosed outer tube. The entire spiral wound unit is PE-coated. This PE material protects the PP material from damage by ultraviolet rays, thereby extending the service life of the structural wall pipe. Furthermore, the PP circumferentially enclosed tube possesses greater strength than the PE circumferentially enclosed outer tube.

[0004] However, despite the good technical effects of the above patented technology, the inventors of this patent discovered that the above porous high-rib reinforced polyethylene winding pipe consists of a pipe body and reinforcing ribs spirally wound around the outside of the pipe body. The pipe body and reinforcing ribs adopt a separate structure, which improves the overall sealing performance of the winding pipe. However, it needs to be manufactured in two steps, which is time-consuming and labor-intensive. In addition, the external reinforcing ribs are easily separated from the pipe body, which defeats the purpose of the reinforcing ribs. The above FRPE reinforced composite winding pipe is wound using winding units with square vertical ribs and an arc-shaped top structure. Since the distance between any two adjacent winding units is difficult to control accurately, the thickness of the melt layer is difficult to control, which makes cracking between the winding units easy to occur. In addition, the space inside the arc-shaped top is large, its load-bearing capacity is limited, and it is easy to collapse, thus affecting the normal use of the winding pipe. Utility Model Content

[0005] The purpose of the present invention is to solve the problems existing in the above-mentioned background technology and provide a double-high-rib fiber continuous co-extruded reinforced winding tube, which, through the improved structural design, is conducive to the formation of a pouring space for molten material between any two adjacent double-high-rib fiber tube bodies, the thickness of the molten material can be controlled more accurately, and the molten material presents a conical structure with a large upper end and a small lower end, which improves the density of the molten material and thus improves the sealing performance of the winding tube. Through the setting of the double-high-rib structure, the contact area between the two adjacent double-high-rib fiber tube bodies is larger, and the bonding and fusion are more firmly achieved, thereby improving the strength of the winding tube.

[0006] The technical solution adopted by the present invention to solve its technical problems is: a double-high-fiber continuous co-extruded reinforced winding tube, the winding tube is formed by winding a tube around a body, and the overlap between any two adjacent tube-wound bodies is provided with molten material, the tube-wound body is a double-high-rib fiber tube body, the outer side of the double-high-rib fiber tube body is provided with two groups of left and right closed reinforcing ribs, the reinforcing ribs are trapezoidal in structure, the upper end length is small, the lower end length is large, the inner side of the double-high-rib fiber tube body is provided with a winding tube base, the interior of the double-high-rib fiber tube body is provided with a fiber reinforcement part, the fiber reinforcement part includes a multi-layer structure of fiber strips. The reinforcing ribs are arranged in a trapezoidal structure, which is conducive to forming a pouring space for the molten material between any two adjacent double-high-rib fiber tube bodies, and makes the molten material present a conical structure with a large upper end and a small lower end.

[0007] Preferably, the reinforcing ribs between any two adjacent double-height fiber tubing bodies form a double-height rib structure, with the molten material disposed between the double-height rib structures. The molten material is used to bond and fuse the two adjacent double-height fiber tubing bodies together. The double-height rib structure increases the contact area between the two adjacent double-height fiber tubing bodies, resulting in a more secure bond. Furthermore, the tapered structure of the molten material, extruded from multiple directions, provides greater density, further enhancing the sealing performance of the spiral wrap.

[0008] Furthermore, the molten material presents a conical structure with a large upper end and a small lower end, which is beneficial to improving the sealing performance of the winding tube.

[0009] Furthermore, the fiber reinforcement part is arranged in the reinforcing rib or in the base surface of the winding tube or in both the base surface of the winding tube and the reinforcing rib. The fiber reinforcement part is a fiber strip with a three-layer structure. The fiber strip is a glass fiber with a thickness of 0.3 mm, and the width can be set as required.

[0010] Furthermore, a support portion with an inverted trapezoidal structure is formed between the reinforcing ribs, which is conducive to dispersing the pressure on the base surface of the winding tube, thereby improving the overall strength of the winding tube.

[0011] Furthermore, the outside of each layer of the fiber strips is coated with a molten material that is the same as the material of the double-high-rib fiber tube body, which enables the fiber strips to be better integrated with the double-high-rib fiber tube body, thereby improving the strength.

[0012] The beneficial effects of the present invention are as follows: (1) the reinforcing ribs are arranged in a trapezoidal structure, which is conducive to forming a pouring space for the molten material between any two adjacent double-high-rib fiber tube bodies, and makes the molten material present a conical structure with a large upper end and a small lower end, thereby improving the density of the molten material, which further improves the sealing performance of the winding tube; (2) the arrangement of the double-high-rib structure makes the contact area between the two adjacent double-high-rib fiber tube bodies larger, the bonding and fusion are more firm, and the bearing capacity of the double-high-rib structure is stronger, thereby improving the strength of the winding tube; (3) an inverted trapezoidal support portion is formed between the reinforcing ribs, which is conducive to dispersing the pressure on the base surface of the winding tube, thereby further improving the overall strength of the winding tube; (4) by arranging a fiber reinforcement portion inside the double-high-rib fiber tube body, a reinforcement structure in multiple directions is formed inside the winding tube, which further improves the strength of the winding tube.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner.

[0021] like Figures 1 to 3 As shown, a double-high fiber continuous co-extruded reinforced winding tube is formed by winding a tube around a body, and the overlap between any two adjacent tube winding bodies is provided with molten material 001. The tube winding body is a double-high fiber tube body 002. The outer side of the double-high fiber tube body 002 is provided with two sets of closed reinforcing ribs 003 on the left and right. The reinforcing ribs 003 have a trapezoidal structure, with a small upper end and a large lower end. The inner side of the double-high fiber tube body 002 is provided with a winding tube base 004. The interior of the double-high fiber tube body 002 is provided with a fiber reinforcement portion 005, which includes a three-layer structure of fiber strips 006. The reinforcing ribs 003 are arranged in a trapezoidal structure, which facilitates the formation of a pouring space for the molten material 001 between any two adjacent double-high fiber tube bodies 002, and makes the molten material 001 present a tapered structure with a large upper end and a small lower end.

[0022] like Figures 1 to 3 As shown, the reinforcing ribs 003 between any two adjacent double-rib fiber tubing bodies 002 form a double-rib structure. The molten material 001 is disposed between the double-rib structures, and is used to bond and fuse the two adjacent double-rib fiber tubing bodies 002 together. The double-rib structure increases the contact area between the two adjacent double-rib fiber tubing bodies 002, resulting in a more secure bond. Furthermore, the tapered structure of the molten material 001 is squeezed from multiple directions due to the tapered angle, resulting in greater density and further improving the sealing performance of the spiral tube.

[0023] like Figures 1 to 5 As shown, the fiber reinforcement 005 can be located within the reinforcing rib 003, within the base surface 004 of the winding tube, or within both the base surface 004 and the reinforcing rib 003. The fiber reinforcement 005 comprises three layers of fiber strips 006. Each layer of fiber strips 006 is made of 0.3mm thick glass fiber, and its width can be adjusted based on actual needs. Each layer of fiber strips 006 is coated with a molten material made from the same material as the double-high-rib fiber tubing body 002, allowing the fiber strips 006 to better integrate with the double-high-rib fiber tubing body 002, thereby increasing its strength.

[0024] like Figure 1 and Figure 2As shown, an inverted trapezoidal support portion 007 is formed between the reinforcing ribs 003. This helps disperse the pressure on the base surface 004 of the spiral tube, thereby improving the overall strength of the spiral tube. Furthermore, in actual applications, since the spiral tube is buried deep underground, the space where the support portion 007 is located is squeezed by the soil, causing the reinforcing ribs 003 to move outward. This creates a compressive force between two adjacent double-height fiber tube bodies 002, further improving the spiral tube's sealing performance and strength.

[0025] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
