Description

Technical Field

[0001] The utility model relates to the technical field of polyolefin pipes, in particular to a PICP double-impeller multi-rib plastic reinforced anti-leakage composite pipe. Background Art

[0002] Polyolefin composite pipe is a composite material pipe made of polyolefin as the main raw material, usually containing a variety of additives and fillers to improve its performance. This type of pipe has good corrosion resistance, heat resistance and mechanical strength, and is widely used in various fields such as chemical, petroleum, natural gas, food, medicine and other industries.

[0003] Currently, there are solid reinforced spiral impeller polyolefin pipes on the market. Their actual reinforcement layer is a solid wave crest. Although the setting of the solid wave crest enhances the compressive strength of the wave crest, it also increases the weight of the wave crest itself. When the wave crest of the pipeline is too heavy, it is easy to cause stress concentration on the outer wall of the pipeline. When the stress on the outer wall of the pipeline is concentrated, it is easy to cause deformation or rupture of the pipeline material, which reduces the anti-penetration ability of the pipeline, thereby increasing the risk of pipeline leakage and shortening the service life of the pipeline.

[0042] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0043] As attached Figure 1 -Attached Figure 3As shown, the embodiment of the present invention provides a PICP double-impeller multi-rib plastic reinforced anti-leakage composite pipe, which is formed by connecting a number of spiral tubular pipe unit bodies S1, wherein the pipe wall of the pipe unit body S1 includes: a trough section 100 formed by a PE body 500, a peak section 200 formed by the PE body 500, and an annular protrusion 400 formed by the PE body 500. The trough section 100 extends along the axial direction of the pipe unit body S1. The trough section 100 formed by the PE body has wear resistance and impact resistance, so that the trough section 100 itself has a certain degree of pressure resistance. The peak section 200 is integrally formed and arranged at both ends of the trough section 100 and extends along the radial direction of the pipe unit body S1. The peak section 200 formed by the PE body also has wear resistance and impact resistance, which also makes the peak section 200 itself have a certain degree of pressure resistance. Specifically, the peak section 200 is composed of a first rib 210, a second rib 220 and a third rib 230, wherein the first rib 210 is arranged in the radial direction of the end face of the trough section 100, and the second rib 220 is arranged on the end face of the adjacent trough section 100 at a slight inclination relative to the first rib 210. A portion of the end of the second rib 220 connected to the first rib 210 is slightly curved in an arc shape, the main purpose of which is to expand the area of ​​the top of the peak section 200 that bears external force and improve the compressive strength of the top of the peak section 200. Figure 3As shown, the first rib 210, the second rib 220 and the trough section 100 form a triangular structure. The setting of the triangular structure greatly increases the compressive strength and stability of the peak section 200 in actual application scenarios. When an external force is applied to the peak section 200, the peak section 200 with compressive strength and stability will reduce the loss of the trough section 100 and also reduce the probability of deformation or rupture of the trough section 100 due to the peak section 200. Moreover, the triangle formed by the first rib 210, the second rib 220 and the trough section 100 is a hollow structure. The peak section 200 with a hollow structure greatly reduces the weight of the peak section 200 itself compared to the solid peak section 200. As the weight of the peak section 200 is reduced, the loss of the peak section 200 to the trough section 100 will be reduced again. The trough section 100 will not suffer from stress concentration problems due to the peak section 200 being too heavy, causing the trough section 100 to deform or rupture, thereby further avoiding the risk of leakage of the polyolefin composite pipe S due to deformation or rupture of the trough section 100 in actual applications, thereby reducing the risk of the anti-permeation ability of the polyolefin composite pipe S. Furthermore, in order to further improve the compressive strength and stability of the peak section 200, a third rib 230 is provided between the first rib 210 and the second rib 220. An angle is formed between one end of the third rib 230 and the end of the first rib 210 away from the trough section 100. The angle is approximately between sixty and thirty degrees. It mainly provides support for the top of the peak section 200. The third rib 230 is lighter or smaller than the first rib 210 and the second rib 220 in terms of weight and size. The purpose of this arrangement is mainly to once again reduce the weight of the peak section 200 itself.

[0044] Furthermore, in order to improve the deformation resistance and compression resistance of the trough section 100, an inner steel wire 300 is embedded below the first rib 210 and the second rib 220, that is, near the end of the axial length direction of the trough section 100. The inner steel wire 300 is spirally wound along the axial direction of the pipe section unit S1 inside the trough section 100. The inner steel wire 300 can provide additional strength and toughness, which not only further improves the deformation resistance and compression resistance of the trough section 100, but also enhances the bearing capacity and stiffness of the peak section 200, and improves the compression resistance of the peak section 200. In order to further protect the trough section 100 from deformation or rupture caused by impact or compression of external forces, in any pipe section unit body S1, an annular protrusion component 400 is provided between the peak sections 200 and the peak sections 200, that is, in the axial direction of the trough section 100. The annular protrusion component 400 is hollow. The purpose of such a setting is to reduce the weight of the annular protrusion component 400 itself, thereby reducing the loss of the trough section 100 caused by the weight of the annular protrusion component 400 itself. The height of the highest point of the annular protrusion component 400 along the radial direction of the trough section 100 is close to half the height of the peak section 200. The length of the annular protrusion component 400 along the axial direction of the trough section 100 accounts for approximately one-third of the length of the entire trough section 100. Without considering the cost, the length of the annular protrusion component 400 along the axial direction of the trough section 100 can also be extended to the second rib 220, so that the protection of the trough section 100 will be maximized.

[0045] like Figure 2As shown, a PE layer S4 is provided between each pipe segment unit body S1. The PE layer S4 is used to bond each pipe segment unit body S1 to form the polyolefin composite pipe S. The PE layer S4 is provided between adjacent peak sections 200. The advantage of using the PE layer S4 to bond adjacent peak sections 200 is that the PE layer S4 itself, in addition to being able to withstand large impact forces and possessing very high strength, also has a certain degree of penetration resistance. Based on these characteristics of the PE layer S4, the adjacent peak sections 200 are made more resistant to pressure and penetration. Furthermore, a PE top cap S2 is commonly provided at the top between adjacent wave peak sections 200. The PE top cap S2 is made of PE material with good elasticity, which can protect the adjacent wave peak sections 200 and improve the service life of the polyolefin composite pipe S. The shape of the bottom of the PE top cap S2 is adapted to the shape of the top between the adjacent wave peak sections 200. The PE top cap S2 makes the two adjacent wave peak sections 200 fit more closely, avoiding the situation where the adhesive connection between the adjacent wave peak sections 200 is slightly misaligned under the action of external force, reducing the sealing and stability between the adjacent wave peak sections 200, thereby avoiding the situation where the stability of the entire polyolefin composite pipe S is reduced. In order to further improve the pressure resistance of the PE top cap S2, an outer steel wire S3 is further provided inside the PE top cap S2. The outer steel wire S3 can provide additional strength and toughness to the PE top cap S2, helping the PE top cap S2 to better withstand the impact and extrusion of external forces. Preferably, as Figure 2 As shown, the outer steel wire S3 is arranged in the middle position of the PE top cap S2 opposite the intersection between adjacent wave peak sections 200, so that the force on both sides is evenly distributed and the PE top cap S2 is prevented from shifting. In addition, the number of outer steel wires S3 can be adjusted according to the needs of actual application scenarios so as to optimize the bearing capacity of the PE top cap S2 and thus optimize the compressive resistance between the PE top caps S2.

[0046] In the structure of this embodiment, the pipe segment unit S1, constructed from the PE main body 500, inherently possesses high hardness, endowing the polyolefin composite pipe S with a certain degree of compressive strength. Furthermore, the hollow triangular structure formed by the first ribs 210, the second ribs 220, and the trough section 100 not only ensures the compressive strength of the peak section 200 but also reduces its own weight, preventing the trough section 100 from deforming or rupturing due to excessive weight, thereby preventing the polyolefin composite pipe S from leaking. Furthermore, to further enhance the compressive strength and stability of the peak section 200, a third rib 230 is provided between the first rib 210 and the second rib 220.

[0047] Furthermore, in order to improve the compressive strength and anti-penetration ability between adjacent peak sections 200, this embodiment adopts the following two methods:

[0048] 1. Use the black fiber PE layer S4 to bond the adjacent peak sections 200 between the adjacent pipe section units S1.

[0049] 2. A PE top cap S2 is provided at the top between adjacent peak sections 200. In order to optimize the compressive strength of the PE top cap S2, an outer steel wire S3 is further provided inside the PE top cap S2. The outer steel wire S3 can provide additional strength and toughness for the PE top cap S2, helping the PE top cap S2 to better withstand the impact and extrusion of external forces. Preferably, the number of outer steel wires S3 can be adjusted according to the needs of the actual application scenario.

[0050] Finally, in order to improve the compressive strength of the trough section 100, this embodiment adopts the following two methods:

[0051] 1. An inner steel wire 300 is embedded below the first rib 210 and the second rib 220 , that is, near the end of the trough section 100 in the axial direction.

[0052] 2. In any pipe segment unit body S1 , an annular protruding component 400 is provided between the peak segments 200 and the peak segments 200 , that is, in the axial direction of the trough segment 100 .

[0053] The structure of the present invention not only ensures the compressive strength of the polyolefin composite pipe S, but also avoids the situation in which stress concentration occurs on the outer wall of the polyolefin composite pipe S due to the peak section 200 being too heavy, thereby causing the polyolefin composite pipe S to deform or rupture, reducing the anti-permeation ability of the polyolefin composite pipe S, increasing the risk of leakage of the polyolefin composite pipe S, and shortening the service life of the polyolefin composite pipe S.

[0054] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
