Description

Technical Field

[0001] The utility model relates to the technical field of corrugated pipes, in particular to an FRPP glass fiber corrugated pipe. Background Art

[0002] A corrugated pipe is a pipe with a corrugated structure, usually used for transporting fluids (such as liquids or gases). They are known for their flexibility, lightness, and good sealing performance, including a corrugated pipe with a non-integral structure composed of multiple components. Compared with an integral corrugated pipe, this structure allows only specific parts to be replaced when damaged or worn, rather than the entire pipe, and the lengths, diameters, or materials of the individual components can also be adjusted as needed to adapt to different installation environments and working conditions; such corrugated pipes are commonly used in cable protection, drainage systems, and ventilation systems, facilitating connection with other pipe systems.

[0003] The prior art has the following deficiencies: The existing non-integral structure corrugated pipes are connected by multiple annular structures and are usually used for the outer protection of pipelines; in the design of these corrugated pipes, in order to ensure their excellent bending performance, there are usually gaps between the individual annular structures, and these gaps can maintain good sealing only when subjected to a certain amount of extrusion during bending. When not bent, there may be voids between the arc-shaped connection structures, which may allow external contaminants (such as dust, sand particles, moisture, etc.) to enter the interior of the pipe, resulting in pipe blockage or corrosion, thereby affecting the normal use of the pipe; moreover, due to the seam design between the annular structures of the non-integral structure corrugated pipe, its compressive strength is relatively low compared to integral corrugated pipes, and leakage or deformation may occur under relatively high pressure; generally speaking, the existing non-integral corrugated pipes have advantages in bending performance, but may face problems with sealing and durability.

[0004] Therefore, it is necessary to invent an FRPP glass fiber corrugated pipe. Summary of the Utility Model

[0005] In order to achieve the above object, the utility model provides the following technical solution: An FRPP glass fiber corrugated pipe includes a first annular member and a second annular member. Both the first annular member and the second annular member are circular ring structures. A dome-shaped convex ring is provided on the surface of the first annular member, and a first glass fiber pipe is embedded inside the dome-shaped convex ring. A flat-topped convex ring is provided on the surface of the second annular member, and a second glass fiber pipe is embedded inside the flat-topped convex ring. Connecting structures are installed at one end of both the first annular member and the second annular member, and the connecting structures are used to connect a plurality of first annular members and second annular members to form a tubular structure.

[0006] Preferably, the connecting structure includes an arc-shaped interface, the arc-shaped interface is fixedly installed at one end of the first annular member, the arc-shaped interface is a circular ring structure, and the cross-section of the arc-shaped interface is arc-shaped.

[0007] Preferably, a sealing rubber ring is pasted on the inner wall of the arc-shaped interface, and the arc-shaped interface is sleeved on one end of the adjacent first annular member or second annular member where the connection structure is not installed.

[0009] Preferably, a sealing rubber ring is pasted on the inner wall of the flat interface, and the flat interface is sleeved on one end of the adjacent first annular member or second annular member where the connection structure is not installed.

[0010] Preferably, the first annular member is arranged at the bent part of the corrugated pipe body. The dome-shaped convex ring is a hollow ring structure, the top of the cross-section of the dome-shaped convex ring is arc-shaped, and the first glass fiber tube is embedded and installed at the four corners of the cross-section of the dome-shaped convex ring.

[0011] Preferably, the second annular member is arranged at the straight part of the corrugated pipe body. The flat-top convex ring is a hollow ring structure, the top of the cross-section of the flat-top convex ring is flat, and the second glass fiber tube is embedded and installed at the four corners of the cross-section of the flat-top convex ring.

[0012] The beneficial effects of the present utility model are as follows: The connection structure of the present utility model is divided into two types suitable for bending state and straight state, and are respectively installed on the first annular member and the second annular member. Through the connection structure suitable for the bending state, a plurality of first annular members are arranged and combined at the bent part of the corrugated pipe.

[0017] The preferred embodiments of the present utility model will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present utility model, and are not used to limit the present utility model.

[0018] Embodiment 1

[0019] As Figure 1 - Figure 3 shown, a kind of FRPP fiberglass corrugated pipe in the first aspect embodiment of the present utility model includes a first annular member 11 and a second annular member 21. Both the first annular member 11 and the second annular member 21 are in a circular ring structure. A dome-shaped convex ring 13 is arranged on the surface of the first annular member 11, and a first fiberglass tube 14 is embedded inside the dome-shaped convex ring 13. A flat-top convex ring 23 is arranged on the surface of the second annular member 21, and a second fiberglass tube 24 is embedded inside the flat-top convex ring 23. Connecting structures are installed at one end of both the first annular member 11 and the second annular member 21. The connecting structures are used to connect a plurality of the first annular members 11 and the second annular members 21 to form a tubular structure.

[0020] In the above embodiment, it should be noted that both the first fiberglass tube 14 and the second fiberglass tube 24 are made of FRPP glass fiber and have relatively high structural strength and tensile resistance. The connecting structures in the present utility model are divided into two types applicable to the bending state and the straight state, and are respectively installed on the first annular member 11 and the second annular member 21. A plurality of the first annular members 11 are arranged and combined in the bending part of the corrugated pipe through the connecting structure applicable to the bending state, and then a plurality of the second annular members 21 are arranged and combined in the straight part of the corrugated pipe through the connecting structure applicable to the straight state. Finally, fiberglass tubes are embedded in the convex ring structures on the surfaces of the first annular member and the second annular member, so as to achieve the effect of flexibly distributing and setting the connecting parts according to the actual situation. Compared with the corrugated pipe using a single connecting structure, it has better bending performance and sealing performance. And the fiberglass tubes strengthen the compressive strength of each annular member and reduce the possibility of leakage or deformation of the corrugated pipe under higher pressure.

[0021] Embodiment 2

[0022] As Figure 1 - Figure 3As shown in the figure, a FRPP fiberglass corrugated pipe includes all the contents of Embodiment 1. In addition, the connection structure includes an arc-shaped interface 12, which is fixedly installed at one end of the first annular member 11. The arc-shaped interface 12 is a ring structure, and the cross-section of the arc-shaped interface 12 is arc-shaped. A sealing rubber ring is pasted on the inner wall of the arc-shaped interface 12. The arc-shaped interface 12 is sleeved on one end of the adjacent first annular member 11 or the second annular member 21 where the connection structure is not installed. The first annular member 11 is arranged at the bent part of the corrugated pipe body. The dome-shaped convex ring 13 is a hollow ring structure, and the top of the cross-section of the dome-shaped convex ring 13 is arc-shaped. The first fiberglass pipe 14 is embedded and installed at the four corners of the cross-section of the dome-shaped convex ring 13.

[0023] In the above embodiment, it should be noted that the arc-shaped interface 12 has the characteristic of being suitable for bending and can maintain sealing in the bent state. By means of the arc-shaped interface 12, the effect of combining multiple first annular members 11 at the bent part of the corrugated pipe can be achieved; the dome-shaped convex ring 13 belongs to the basic structure of the corrugated pipe and has the function of improving the compressive and tensile resistance of the first annular member 11.

[0024] Embodiment 3

[0025] As Figure 1 - Figure 3 As shown in the figure, a FRPP fiberglass corrugated pipe includes all the contents of Embodiment 2. In addition, the connection structure includes a flat interface 22, which is fixedly installed at one end of the second annular member 21. The flat interface 22 is a ring structure, and the cross-section of the flat interface 22 is strip-shaped. A sealing rubber ring is pasted on the inner wall of the flat interface 22. The flat interface 22 is sleeved on one end of the adjacent first annular member 11 or the second annular member 21 where the connection structure is not installed. The second annular member 21 is arranged at the straight part of the corrugated pipe body. The flat-top convex ring 23 is a hollow ring structure, and the top of the cross-section of the flat-top convex ring 23 is flat. The second fiberglass pipe 24 is embedded and installed at the four corners of the cross-section of the flat-top convex ring 23.

[0026] In the above embodiment, it should be noted that the flat interface 22 is not suitable for bending, but has strong sealing performance in the straight state. By means of the flat interface 22, the effect of combining multiple second annular members 21 at the straight part of the corrugated pipe can be achieved; the flat-top convex ring 23 belongs to the basic structure of the corrugated pipe and has the function of improving the compressive and tensile resistance of the second annular member 21; there is no essential difference between the dome-shaped convex ring 13 and the flat-top convex ring 23. The difference in structure between the dome-shaped convex ring 13 and the flat-top convex ring 23 is used to distinguish the first annular member 11 and the second annular member 21, which is convenient for workers to quickly find and use the correct annular member during the assembly of the corrugated pipe.

[0027] The usage process of the present utility model is as follows: Those skilled in the art set and combine multiple first annular members 11 with arc-shaped interfaces 12 at the bending part of the corrugated pipe according to the actual situation, and then set and combine multiple second annular members 21 with flat interfaces 22 at the straight part of the corrugated pipe to obtain a corrugated pipe with excellent bending performance and sealing performance in each part.

[0028] As described above, it is only a preferred embodiment of the present utility model.
