[0027] Reference Figs. 1 to 4 A steel wire mesh framework composite pipe according to a preferred embodiment of the present application will be described in detail below, wherein the steel wire mesh framework composite pipe comprises a pipe core layer 10, a framework layer 20, an inner cladding layer 30, a first reinforcing layer 40 and an outer cladding layer 50.

[0028] Specifically, the framework layer 20 clads the pipe core layer 10, and the framework layer 20 is clad by the inner cladding layer 30, the first reinforcing layer 40 and the outer cladding layer 50 in sequence.

[0029] In the present embodiment, the framework layer 20 comprises a plurality of axial ribs 21 and at least one circumferential rib 22. The plurality of axial ribs 21 are arranged on the circumferential surface of the pipe core layer 10 in a coaxial manner in the circumferential direction. The circumferential rib 22 is arranged on the outer periphery of the pipe core layer 10 in a spiral manner along the extension direction of the pipe core layer 10, and the circumferential rib 22 is integrally welded with each axial rib 21 at the intersection.

[0030] It is worth mentioning that the skeleton layer 20 is arranged to improve the overall compression resistance and impact resistance of the steel wire mesh skeleton composite pipe.

[0031] In another variant embodiment, the skeleton layer 20 includes at least two circumferential ribs 22. Both of the two circumferential ribs 22 are arranged on the outer periphery of the pipe core layer 10 in a spiral manner along the extension direction of the pipe core layer 10, and the spiral directions of the two circumferential ribs 22 are opposite. The two circumferential ribs 22 are welded together at the intersection.

[0032] In order for those skilled in the art to understand the present application, in at least one embodiment of the present application, only the skeleton layer 20 includes a plurality of axial ribs 21 and at least one circumferential rib 22, the plurality of axial ribs 21 are arranged on the circumferential surface of the pipe core layer 10 in a coaxial manner, the circumferential rib 22 is arranged on the outer periphery of the pipe core layer 10 in a spiral manner along the extension direction of the pipe core layer 10, and the circumferential rib 22 is welded to each axial rib 21.

[0033] Preferably, the pitch of the spiral of the circumferential rib 22 arranged on the outer peripheral surface of the pipe core layer 10 along the extension direction is variable.

[0034] It is worth mentioning that the steel wire mesh skeleton composite pipe is used, and the pressure and impact force received by different parts in the extension direction are different. Since the pitch of the spiral of the circumferential rib 22 arranged on the outer peripheral surface of the pipe core layer 10 along the extension direction is variable, the compression resistance and impact resistance of the pipe core layer 10, the skeleton layer 20, the inner cover layer 30, the first reinforcing layer 40 and the outer cover layer 50 at different positions along the extension direction can be changed to cope with different use cases, while improving the utilization of the circumferential rib 22.

[0035] Preferably, the axial rib 21 and the circumferential rib 22 are implemented as steel wires.

[0036] Specifically, a plurality of skeleton through holes are formed between the circumferential rib 22 and the plurality of axial ribs 21. When the inner cover layer 30 covers the skeleton layer 20, it can enter the skeleton through hole and be connected to the surface of the pipe core layer 10 to enhance the stability of the skeleton layer 20 between the pipe core layer 10 and the inner cover layer 30.

[0037] In this embodiment, the first reinforcing layer 40 is a plurality of steel wires arranged on the circumferential surface of the inner cover layer 30 in an equal-pitch spiral manner along the extension direction of the inner cover layer 30.

[0038] It is worth mentioning that, when the inner side of the pipe core layer 10 is subjected to pressure and impact force, the pressure and impact force are sequentially conducted to the first reinforcing layer 40 through the pipe core layer 10, the framework layer 20 and the inner cover layer 30, the first reinforcing layer 40 is slightly deformed to absorb the pressure and impact force, thereby improving the overall pressure resistance and impact resistance of the pipe core layer 10, the framework layer 20, the inner cover layer 30, the first reinforcing layer 40 and the outer cover layer 50. At the same time, since the first reinforcing layer 40 is slightly deformed to absorb the pressure and impact force, the axial ribs 21 and the circumferential ribs 22 of the framework layer 20 are prevented from being broken due to the pressure and impact force, so that the framework layer 20 can normally play a role.

[0039] Further, when the outer side of the outer cover layer 50 is subjected to pressure and impact force, the pressure and impact force are conducted to the first reinforcing layer 40 through the outer cover layer 50, the first reinforcing layer 40 is slightly deformed to absorb the pressure and impact force, thereby improving the overall pressure resistance and impact resistance of the pipe core layer 10, the framework layer 20, the inner cover layer 30, the first reinforcing layer 40 and the outer cover layer 50. At the same time, since the first reinforcing layer 40 is slightly deformed to absorb the pressure and impact force, the axial ribs 21 and the circumferential ribs 22 of the framework layer 20 are prevented from being broken due to the pressure and impact force, so that the framework layer 20 can normally play a role.

[0040] In another variant embodiment, the first reinforcing layer 40 is a plurality of steel wires arranged on the circumferential surface of the inner cover layer 30 in a spiral manner along the extension direction of the inner cover layer 30, and the pitch of the spiral of the first reinforcing layer 40 is variable, thereby improving the pressure resistance and impact resistance suitable for actual use conditions obtained by different parts of the pipe core layer 10, the framework layer 20, the inner cover layer 30, the first reinforcing layer 40 and the outer cover layer 50 in the overall extension direction.

[0041] In order for those skilled in the art to understand the present application, in at least one embodiment of the present application, only the first reinforcing layer 40 is a plurality of steel wires arranged on the circumferential surface of the inner cover layer 30 in a spiral manner along the extension direction of the inner cover layer 30.

[0042] Preferably, the pipe core layer 10, the inner cover layer 30 and the outer cover layer 50 are implemented to include but not limited to polyethylene and resin selected from the group consisting of.

[0043] Preferably, the steel wire mesh framework composite pipe further comprises at least one second reinforcing layer 60, and the second reinforcing layer 60 is arranged between the first reinforcing layer 40 and the outer cover layer 50.

[0044] In the embodiment, the second reinforcing layer 60 is a plurality of steel wires arranged outside the first reinforcing layer 40 in the extension direction of the first reinforcing layer 40 in the form of a helix with equal pitch. The helix direction of the steel wires of the second reinforcing layer 60 is opposite to the helix direction of the steel wires of the first reinforcing layer 40, and the helix pitch of the steel wires of the second reinforcing layer 60 is the same as the helix pitch of the steel wires of the first reinforcing layer 40.

[0045] In another variant, the second reinforcing layer 60 is a plurality of steel wires arranged outside the first reinforcing layer 40 in the extension direction of the first reinforcing layer 40 in the form of a helix with equal pitch. The helix direction of the steel wires of the second reinforcing layer 60 is opposite to the helix direction of the steel wires of the first reinforcing layer 40, and the helix pitch of the steel wires of the second reinforcing layer 60 is different from the helix pitch of the steel wires of the first reinforcing layer 40.

[0046] In yet another variant, the second reinforcing layer 60 is a plurality of steel wires arranged outside the first reinforcing layer 40 in the extension direction of the first reinforcing layer 40 in the form of a helix with equal pitch. The helix direction of the steel wires of the second reinforcing layer 60 is the same as the helix direction of the steel wires of the first reinforcing layer 40, and the helix pitch of the steel wires of the second reinforcing layer 60 is different from the helix pitch of the steel wires of the first reinforcing layer 40.

[0047] To enable those skilled in the art to understand the present application, in at least one embodiment of the present application, only the second reinforcing layer 60 is a plurality of steel wires arranged outside the first reinforcing layer 40 in the extension direction of the first reinforcing layer 40 in the form of a helix with equal pitch, the helix direction of the steel wires of the second reinforcing layer 60 is opposite to the helix direction of the steel wires of the first reinforcing layer 40, and the helix pitch of the steel wires of the second reinforcing layer 60 is the same as the helix pitch of the steel wires of the first reinforcing layer 40.

[0048] It is worth mentioning that after the first reinforcing layer 40 produces slight deformation to absorb pressure and impact force, the second reinforcing layer 60 can further produce slight deformation to absorb the remaining pressure and impact force, thereby reducing the influence of pressure and impact force on the axial rib 21 and the circumferential rib 22 as a whole, so as to ensure that the framework layer 20 can normally play a role.

[0049] As an example, when the inner side of the pipe core layer 10 is subjected to pressure and impact force, the pressure and impact force are conducted to the first reinforcing layer 40 and the second reinforcing layer 60 through the pipe core layer 10, the skeleton layer 20, and the inner cover layer 30 in sequence, the first reinforcing layer 40 and the second reinforcing layer 60 generate slight deformation to absorb the pressure and impact force in sequence, thereby improving the overall pressure resistance and impact resistance of the pipe core layer 10, the skeleton layer 20, the inner cover layer 30, the first reinforcing layer 40, the outer cover layer 50, and the second reinforcing layer 60. At the same time, since the first reinforcing layer 40 and the second reinforcing layer 60 generate slight deformation to absorb the pressure and impact force, the axial ribs 21 and the circumferential ribs 22 of the skeleton layer 20 are prevented from being broken due to the pressure and impact force.

[0050] Further, when the outer side of the outer cover layer 50 is subjected to pressure and impact force, the pressure and impact force are conducted to the second reinforcing layer 60 and the first reinforcing layer 40 through the outer cover layer 50 in sequence, the second reinforcing layer 60 and the first reinforcing layer 40 generate slight deformation to absorb the pressure and impact force in sequence, thereby improving the overall pressure resistance and impact resistance of the pipe core layer 10, the skeleton layer 20, the inner cover layer 30, the first reinforcing layer 40, the outer cover layer 50, and the second reinforcing layer 60. At the same time, since the second reinforcing layer 60 and the first reinforcing layer 40 generate slight deformation to absorb the pressure and impact force in sequence, the axial ribs 21 and the circumferential ribs 22 of the skeleton layer 20 are prevented from being broken due to the pressure and impact force.

[0051] It is worth mentioning that when a plurality of steel wires simultaneously cover the inner cover layer 30 in the form of equal-pitch spirals to form the first reinforcing layer 40, since the plurality of steel wires simultaneously cover the inner cover layer 30, the rate of setting the first reinforcing layer 40 outside the inner cover layer 30 can be improved.

[0052] Similarly, when a plurality of steel wires simultaneously cover the first reinforcing layer 40 in the form of equal-pitch spirals to form the second reinforcing layer 60, since the plurality of steel wires simultaneously cover the first reinforcing layer 40, the rate of setting the second reinforcing layer 60 outside the first reinforcing layer 40 can be improved.

[0053] As an example, the first reinforcing layer 40 can cover the inner cover layer 30 in a manner that the temperature of the first reinforcing layer 40 is higher than the melting point of the inner cover layer 30, so that when the first reinforcing layer 40 covers the inner cover layer 30, the first reinforcing layer 40 melts the inner cover layer 30 at the contact position with the inner cover layer 30 and sinks into the inner cover layer 30, thereby improving the stability of the first reinforcing layer 40 covering the inner cover layer 30.

[0054] In the embodiment, the steel wire mesh skeleton composite pipe further comprises at least one adhesive layer 70. The adhesive layer 70 is arranged between the second reinforcing layer 60 and the outer cover layer 50 in a manner of being able to flow into the gap between the second reinforcing layer 60 and the outer cover layer 50.

[0055] In another variant embodiment, the steel wire mesh skeleton composite pipe further comprises a plurality of adhesive layers 70. The plurality of adhesive layers 70 are respectively arranged between the second reinforcing layer 60 and the outer cover layer 50, between the pipe core layer 10 and the skeleton layer 20, between the skeleton layer 20 and the inner cover layer 30, between the inner cover layer 30 and the first reinforcing layer 40, between the first reinforcing layer 40 and the second reinforcing layer 60, and between the second reinforcing layer 60 and the outer cover layer 50.

[0056] In order for those skilled in the art to understand the present application, in at least one embodiment of the present application, only the steel wire mesh skeleton composite pipe further comprises at least one adhesive layer 70, the adhesive layer 70 is arranged between the second reinforcing layer 60 and the outer cover layer 50 in a manner of being able to flow into the gap between the second reinforcing layer 60 and the outer cover layer 50 is taken as an example for description.

[0057] Preferably, the second reinforcing layer 60 is implemented to include but not limited to selected from resin.

[0058] It is worth mentioning that when the adhesive layer 70 is arranged between the second reinforcing layer 60 and the outer cover layer 50, since the adhesive layer 70 can flow into the gap between the second reinforcing layer 60 and the outer cover layer 50, and the adhesive layer 70 itself has adhesion, thereby the stability of the outer cover layer 50 covering the second reinforcing layer 60 can be improved, so as to prevent the outer cover layer 50 from falling off from the outside of the second reinforcing layer 60.

[0059] Those skilled in the art should understand that the embodiments of the present application shown in the above description and the drawings are only taken as examples and do not limit the present application. The advantages of the present application have been completely and effectively realized.
