Description

Technical Field

[0001] This utility model relates to the field of plastic pipe production technology, specifically to a continuously wound reinforced structural wall pipe. Background Technology

[0002] Continuously wound reinforced structural wall pipe is a high-performance composite pipe with unique structural and material advantages. It is widely used in many fields, mainly for drainage, sewage, and rainwater collection systems. It is especially suitable for large-diameter pipe requirements, leachate collection pipes in sewage treatment plants and landfills, etc.

[0003] Most of the currently available continuously wound pipes have spiral stripes added to the outer wall of the pipe to enhance the pipe wall strength. However, since the added stripes are integrally formed with the pipe and are mostly solid, although they can enhance the strength of the pipe itself, the material savings are still relatively limited. Furthermore, when subjected to external forces, they lack buffering capacity, and the support strength of the stripes alone is still insufficient.

[0004] Therefore, a continuously wound reinforced structural wall pipe is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a continuously wound reinforced structural wall pipe, which can solve the problem of further improving pipe strength while saving on production material consumption.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a continuously wound reinforced structural wall pipe, comprising a support pipe, and a strip plate spirally wound around the outer wall of the support pipe and perpendicular to the outer wall of the support pipe.

[0007] Connecting plates are symmetrically installed on both sides of the end of the strip plate away from the support tube. The other end of the connecting plate is away from the strip plate and inclined towards the support tube. A support plate is also connected to the bottom of the connecting plate, and the support plate is set parallel to the strip plate.

[0008] Preferably, the support tube, strip plate, connecting plate, and support plate are all composite materials made of polymer, glass fiber, and carbon fiber.

[0009] Preferably, a second filling block is provided on both sides between the strip plate and the outer wall of the support tube. One side of the second filling block is fixed to the strip plate and the other side is fixed to the support tube, and the outer wall of the second filling block has an arc-shaped cross-section.

[0010] Preferably, a first filling block is provided between the strip plate and the connecting plate, one side of the first filling block is fixed to the strip plate, and the other side of the first filling block is fixed to the connecting plate, and an arc-shaped cross-section is provided on the outer wall of the first filling block.

[0011] Preferably, an arc-shaped plate is provided between the support plate and the connecting plate, with one side of the arc-shaped plate fixed to the support plate and the other side of the arc-shaped plate fixed to the connecting plate.

[0012] Preferably, a spiral guide strip is installed along the inner wall of the support tube, and the frontal projection of the guide strip is located between adjacent strip plates.

[0013] Compared with the prior art, this utility model provides a continuously wound reinforced structural wall pipe, which has the following beneficial effects:

[0014] 1. This utility model forms a multi-layered support structure by setting spiral strip plates, connecting plates and support plates on the outer wall of the support pipe, which significantly improves the overall stress strength of the pipe. At the same time, the inclined design of the connecting plates and the parallel arrangement of the support plates enable the pipe to disperse pressure through elastic deformation when subjected to external forces, providing a better buffering effect and avoiding damage caused by local stress concentration.

[0015] 2. This utility model uses an arc-shaped structure composed of strip plates, connecting plates, and supporting plates to form a hollow structure while ensuring support strength and buffering effect, thereby reducing material consumption and production costs. In particular, the setting of arc-shaped cut surfaces and arc-shaped plates further optimizes material distribution and achieves a balance between lightweight and high strength.

[0016] 3. This utility model can guide the liquid to form a spiral flow by supporting the spiral guide strip on the inner wall of the pipe, thereby reducing flow resistance and increasing the flow rate of the liquid in the pipe. It is especially suitable for drainage, sewage discharge and other scenarios. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example:

[0024] Please see Figure 1 - Figure 4 In this embodiment, a continuously wound reinforced structural wall pipe includes a support pipe 1. A strip plate 2 is installed on the outer wall of the support pipe 1 in a spiral shape around the outer wall of the support pipe 1. The strip plate 2 is perpendicular to the outer wall of the support pipe 1 and forms a continuously wound protrusion on the outer wall of the support pipe 1 to improve the overall stress strength of the pipe wall of the support pipe 1.

[0025] Connecting plates 3 are symmetrically installed on both sides of the end of the strip plate 2 away from the support pipe 1. The other end of the connecting plate 3 is away from the strip plate 2 and inclined towards the support pipe 1, which increases the contact surface of the strip plate 2 when it comes into contact with external force, so that the strip plate 2 can fully contact the external force when it is subjected to force, and the external force can be stably applied to the strip plate 2 and transmitted to the support pipe 1. A support plate 4 is also connected to the bottom of the connecting plate 3, and the support plate 4 is set parallel to the strip plate 2.

[0026] It should be noted that the support pipe 1, strip plate 2, connecting plate 3, and support plate 4 are all composite materials made of polymer, glass fiber, and carbon fiber. The polymer is either HDPE or PVC, which ensures that it will deform to a certain extent when in contact with external force, thus providing elasticity. The glass fiber and carbon fiber, on the other hand, improve the strength of the pipe itself.

[0027] Specifically, when strip plate 2 or connecting plate 3 is subjected to force, strip plate 2 deforms under pressure. At this time, support plate 4 will contact the outer wall of support pipe 1. The inclined setting of connecting plate 3 makes the angle between connecting plate 3 and support plate 4 wide, that is, the angle range between connecting plate 3 and support plate 4 is 90°≤A≤180°. Therefore, after support plate 4 contacts the outer wall of support pipe 1, it will slide along the outer wall of support pipe 1, and the elastic effect will be generated between support plate 4 and connecting plate 3, as well as between strip plate 2 and connecting plate 3, so that it has the tendency to return to the initial state. The multi-area contact and multi-position deformation greatly increase the generation of elastic force, which will restore the initial state and provide more force to improve the buffering effect of support pipe 1 after contact with external force.

[0028] It should be noted that in actual use, the side of the support plate 4 closest to the support tube 1 is an arc-shaped convex surface. This reduces the resistance between the support plate 4 and the support tube 1 when the support plate 4 contacts the support tube 1, allowing the support plate 4 to slide more easily along the outer wall of the support tube 1 after contact, so that the tube can provide a faster buffering feedback after being subjected to force.

[0029] In order to improve the bending effect between the support plate 4 and the connecting plate 3, an arc plate 7 is provided between the support plate 4 and the connecting plate 3. One side of the arc plate 7 is fixed to the support plate 4, and the other side of the arc plate 7 is fixed to the connecting plate 3. In actual use, the arc plate 7 is made of the same material as the support tube 1, which makes it easier for the support plate 4 to deflect on the connecting plate 3, and allows the strip plate 2 to perform the stress relief and buffering operation more quickly after being subjected to force.

[0030] It should be noted that, as Figure 4 As shown, a second filling block 6 is provided on both sides between the strip plate 2 and the outer wall of the support pipe 1. One side of the second filling block 6 is fixed on the strip plate 2 and the other side is fixed on the support pipe 1. The outer wall of the second filling block 6 is an arc-shaped cut surface, so that the connection surface between the strip plate 2 and the support pipe 1 is arc-shaped, which strengthens the support strength between the strip plate 2 and the support pipe 1 without affecting the bending of the strip plate 2 on the support pipe 1.

[0031] In addition, a first filling block 5 is provided between the strip plate 2 and the connecting plate 3. One side of the first filling block 5 is fixed to the strip plate 2, and the other side of the first filling block 5 is fixed to the connecting plate 3. An arc-shaped cut surface is provided on the outer wall of the first filling block 5 so that the connection surface between the strip plate 2 and the connecting plate 3 is also arc-shaped, just like the connection between the strip plate 2 and the support pipe 1, so as to improve the connection strength between the connecting plate 3 and the strip plate 2.

[0032] Furthermore, in order to increase the flow rate of the liquid in the support pipe 1, a spiral guide strip 8 is installed along the inner wall of the support pipe 1. The frontal projection of the guide strip 8 is located between adjacent strip plates 2, which reinforces the area of ​​the support pipe 1 between the strip plates 2, further enhancing the stress strength of the support pipe 1. The liquid entering the support pipe 1 will flow along the guide strip 8 when it flows, so that the liquid has a spiral movement tendency, thereby increasing the flow rate of the liquid in the support pipe 1.

[0033] Specifically, in the actual production process, the strip plate 2, connecting plate 3, and support plate 4 are all plates of uniform thickness, which makes them an integrated structure. That is, during production, they can be continuously wound by an extruder, which facilitates the production of the pipe.

[0034] It needs to be further explained that, such as Figure 4 As shown, the connecting plate 3 connects the strip plate 2 and the support plate 4, so that the connecting plate 3 and the support plate 4 are arranged in a spiral shape on the outside of the support pipe 1, which is consistent with the strip plate 2. That is, a cavity is formed between the support plate 4 and the strip plate 2. During the integral molding, while ensuring good support strength, a lot of material consumption is saved for the production of the pipe, thereby saving production costs.

[0035] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
