Description

Technical Field

[0001] The utility model relates to the technical field of pipe materials, in particular to a strip structure for a hollow winding pipe. Background Art

[0002] In the modern industrial and construction fields, the pipeline system, as a carrier for transporting fluids, gases or other media, its performance and stability are crucial. As an important type of pipeline, the winding pipe is widely used in urban water supply, drainage, agricultural irrigation, oilfield transportation and other fields due to its flexibility, easy installation and durability. However, with the diversification and complexity of application scenarios, traditional winding pipes are unable to cope under certain specific conditions (such as high pressure, deep underground, etc.), especially in terms of compressive performance.

[0003] For example, a PVC ribbed hollow wall reinforced winding pipe disclosed in a Chinese utility model patent with the patent application number 202320367279.1, a hollow square pipe, is spirally wound around an axis. The hollow square pipe is provided with a first side wall, a second side wall, an inner wall and an outer wall; ribs are arranged in the middle of the hollow square pipe, and the ribs connect the inner wall and the outer wall; a coating layer covers the outer wall of the hollow square pipe, and the coating layer includes an adhesion part, an upper covering layer and a lower covering layer. The adhesion part is arranged between the adjacent first side wall and the second side wall of the hollow square pipe, the upper covering layer is arranged on the outer wall, and the lower covering layer is arranged on the inner wall. In this structure, ribs are arranged in the hollow square pipe to support the inner wall of the hollow square pipe, thereby improving the strength of the hollow square pipe.

[0004] However, in the above structure, due to its relatively simple structure and limited compressive capacity, when external irregular stresses act on the side walls and ribs, irregular deformations will occur. Once a certain structure is bent and deformed, it will cause the structure of the entire hollow square pipe to collapse, resulting in the deformation of the pipe wall and the inability to continue providing support. Therefore, its structure is relatively unstable. Summary of the Utility Model

[0005] In order to overcome the deficiencies of the prior art, the utility model provides a strip structure for a hollow winding pipe.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] The strip structure for a hollow winding pipe includes a pipe wall profile with a hollow structure. Clamping structures are provided at both ends of the pipe wall profile. The pipe wall profile spirally extends along the cross-sectional direction and is wound in sequence and then clamped to each other through the clamping structures to form a pipe body. A plurality of tension fiber structures for improving the bending strength of the pipe body are provided on the outer wall of the pipe wall profile. A plurality of support structures for improving the compressive strength of the pipe body are provided at positions corresponding to the tension fiber structures on the inner side of the pipe wall profile. The tension fiber structure includes an embedding groove formed by recessing inward the pipe wall and a fiber board clamped in the embedding groove; the support structure includes a plurality of first support ribs supported on the inner side of the pipe wall profile. One end of the first support rib is connected to the bottom edge of the embedding groove, and the other end extends vertically downward and is connected to the inner wall of the pipe wall profile;

[0008] Two groups of support structures are provided on the inner side of the pipe wall profile. Each group of support structures includes three of the first support ribs. The three first support ribs are respectively connected to the middle and both sides of the bottom edge of the embedding groove. The three first support ribs cooperate with the bottom edge of the embedding groove and the inner wall of the pipe wall profile to form a horizontal "day" character structure.

[0009] Further, the fiber board is made of fiberglass and is filled into the embedding groove by a casting method.

[0010] In the present utility model, two groups of tension fiber structures are provided on the pipe wall profile, and the two groups of tension fiber structures are arranged at intervals. The top plane of the fiber board is flush with the outer side surface of the pipe wall profile, and both sides of the fiber board are respectively abutted against the two side walls of the embedding groove.

[0011] In the present utility model, the clamping structures each include a connecting plug and a connecting slot. The connecting plugs and connecting slots at both ends are oppositely installed. The connecting plug at the left end is connected to the inner wall, and the connecting plug at the right end is connected to the outer wall. The connecting slot at the left end is recessed inward from a position near the edge of the outer wall, and the connecting slot at the right end is recessed outward from a position near the edge of the inner wall.

[0012] Further, the contour of the connecting plug at the left end corresponds to the contour of the connecting slot at the right end, and the contour of the connecting slot at the left end corresponds to the contour of the connecting plug at the right end.

[0013] Further, a second support rib extends inward from the bottom edge of the connecting slot on the outer wall and extends vertically downward to be connected to the inner wall. A third support rib extends inward from the bottom edge of the connecting slot on the inner wall and extends vertically upward to be connected to the outer wall.

[0014] The present utility model has the following advantages and beneficial effects:

[0015] A tension fiber structure is provided on the outer wall of the pipe wall profile, and a support structure is provided at a position corresponding to the tension fiber structure on the inner side of the pipe wall profile. When the pipe body is subjected to external stress, the fiber board in the tension fiber structure resists the bending stress, and the first support rib in the support structure resists the compressive stress, thereby decomposing the stress and making the structure more stable. Therefore, through this structure, the compressive capacity of the pipe wall profile can be greatly improved, thereby improving the overall compressive performance of the strip structure.

The present invention is not limited to the following embodiments.

[0020] It should be noted that if there are directional indications (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...) involved in the embodiments of the present invention, then such directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the drawings). If this specific posture changes, then such directional indications will also change accordingly.

[0021] In addition, if there is a description involving "first" or "second" in the embodiments of the present invention, then such description of "first" or "second" is only for descriptive purposes and cannot be understood as indicating or implying its relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0022] Such as Figures 1 to 2As shown in the figure, this embodiment discloses a strip structure for a hollow winding pipe, including a pipe wall profile 1 with a hollow structure. At both ends of the pipe wall profile 1, there are buckle structures 11. The pipe wall profile 1 spirally extends along the cross-section direction and is sequentially wound and then buckled with each other through the buckle structures 11 to form a pipe body. On the outer wall of the pipe wall profile 1, there are several tension fiber structures 12 for improving the bending strength of the pipe body. At the position corresponding to the tension fiber structures 12 on the inner side of the pipe wall profile 1, there are several support structures 13 for improving the compressive strength of the pipe body. The tension fiber structure 12 includes an embedding groove 121 formed by recessing towards the inner side of the pipe wall and a fiber board 122 clamped in the embedding groove 121. The fiber board 122 is made of fiberglass and is filled into the embedding groove 121 by injection. The support structure 13 includes several first support ribs 131 supported on the inner side of the pipe wall profile 1. Specifically, the top end of the first support rib 131 is connected to the bottom edge of the groove of the embedding groove 121, and the other end of the first support rib 131 extends vertically downward and is connected to the inner wall of the pipe wall profile 1. When the pipe body is subjected to external stress, the fiber board 122 in the tension fiber structure 12 resists the bending stress, and the first support rib 131 in the support structure 13 resists the compressive stress, thereby decomposing the stress and making the structure more stable. Therefore, through this structure, the compressive capacity of the pipe wall profile 1 can be greatly improved, thereby improving the overall compressive performance of the winding pipe.

[0023] In this embodiment, there are two groups of tension fiber structures 12 provided on the pipe wall profile 1, and the two groups of tension fiber structures 12 are arranged at intervals. In the two groups of tension fiber structures 12, the top plane of the fiber board 122 is flush with the outer side surface of the pipe wall profile 1, and both sides of the fiber board 122 are respectively abutted against the two side walls of the embedding groove 121. When the pipe body is subjected to bending stress, the two side walls of the embedding groove 121 will move closer to the inner side, and the fiber board 122 abuts between the two side walls to form a lateral support, thereby resisting this force and achieving the effect of resisting bending.

[0024] Furthermore, there are two groups of support structures 13 provided on the inner side of the pipe wall profile 1 corresponding to the tension fiber structures 12. Each group of support structures 13 includes three first support ribs 131. The three first support ribs 131 are respectively connected to the middle and two side positions of the bottom edge of the embedding groove 121. Therefore, the three first support ribs 131 cooperate with the bottom edge of the embedding groove 121 and the inner wall of the pipe wall profile 1 to form a horizontal "day" character structure. When the pipe body is subjected to compressive stress, the horizontal "day" character structure can form a vertical support through the three support ribs to resist the compressive stress and achieve the effect of resisting compression.

[0025] In this embodiment, the buckle structures 11 at both ends of the pipe wall profile 1 each include a connecting plug 111 and a connecting slot 112. The connecting plugs 111 and connecting slots 112 at both ends are installed opposite to each other. Specifically, the connecting plug 111 at the left end is connected to the inner pipe wall, and the connecting plug 111 at the right end is connected to the outer pipe wall. The connecting slot 112 at the left end is recessed inward from a position near the edge of the outer pipe wall, and the connecting slot 112 at the right end is recessed outward from a position near the edge of the inner pipe wall. Preferably, the contour of the connecting plug 111 at the left end corresponds to the contour of the connecting slot 112 at the right end, and the contour of the connecting slot 112 at the left end corresponds to the contour of the connecting plug 111 at the right end.

[0026] Furthermore, a second support rib 132 extends inward from the bottom edge of the connecting slot 112 on the outer pipe wall. The second support rib 132 extends vertically downward to connect with the inner pipe wall. A third support rib 133 extends inward from the bottom edge of the connecting slot 112 on the inner pipe wall. The third support rib 133 extends vertically upward to connect with the outer pipe wall. The cooperation of the second support rib 132 and the third support rib 133 makes the buckle structure 11 more stable and improves the connection effect between the pipe wall profiles 1.

[0027] What is described above in this specification is only an example of the present invention. Those skilled in the technical field to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar methods to replace them. As long as they do not deviate from the content of this specification of the present invention or exceed the scope defined by this claims, they should fall within the protection scope of the present invention.
