[0034] In this embodiment, if Figure 1 and Figure 2 As shown, an insulation structure for an asphalt diversion pipeline includes a diversion pipeline body 1, an insulation component 2 is installed on the diversion pipeline body 1, and the insulation component 2 is spliced ​​and installed on the outer periphery of the diversion pipeline body 1 to insulate the diversion pipeline body 1. The insulation component 2 includes an insulation sleeve 21, a first protective shell 22 and a second protective shell 23. The insulation sleeve 21 is wrapped around the outer periphery of the diversion pipeline body 1, and the first protective shell 22 is half wrapped around the outer periphery of the insulation sleeve 21. A plug-in plate 24 is fixedly connected to the second protective shell 23, and the plug-in plate 24 is adapted to the limiting groove of the first protective shell 22. The second protective shell 23 is connected to the first protective shell 22 through the plug-in plate 24.

[0035] Thus, the open insulation sleeve 21 is put on the outer periphery of the guide pipe body 1 and fixed, and then the first protective shell 22 is put on the outer wall of the insulation sleeve 21, and the second protective shell 23 and the first protective shell 22 are connected by the plug-in plate 24. The first protective shell 22 and the second protective shell 23 enhance the surface strength of the insulation sleeve 21, and cooperate with the insulation sleeve 21 to prevent heat loss on the surface of the guide pipe body 1. The first protective shell 22 and the second protective shell 23 are both processed with a cavity structure, which is conducive to reducing the damage of the first protective shell 22 and the second protective shell 23 caused by the impact force, and the traditional connection method of multiple rivets between the first protective shell 22 and the second protective shell 23 is changed to make it easier to disassemble.

[0036] Specifically, the first protective shell 22 and the second protective shell 23 are spliced ​​together to form a cylindrical cavity. An opening is processed on the insulation sleeve 21 to facilitate wrapping around the outer wall of the diversion pipeline body 1. A limiting groove adapted to the plug plate 24 is processed in the first protective shell 22.

[0037] In some embodiments, as Figure 4 As shown, reinforcing ribs 25 are fixedly connected to the inner cavities of the first protective shell 22 and the second protective shell 23 , and the reinforcing ribs 25 are used to increase the bearing capacity of the first protective shell 22 and the second protective shell 23 .

[0038] Specifically, the reinforcing ribs 25 are evenly distributed in the inner cavities of the first protective shell 22 and the second protective shell 23. The processing cavities in the first protective shell 22 and the second protective shell 23 form a double-layer structure, which increases the buffering effect of the first protective shell 22 and the second protective shell 23 and prevents the single-layer protective structure from being directly damaged and causing damage to the insulation sleeve 21.

[0039] In some embodiments, as Figure 5 As shown, a reinforcement component 3 is installed on the first protective shell 22, and the reinforcement component 3 is used to seal the seam between the first protective shell 22 and the second protective shell 23. The reinforcement component 3 includes a flexible connecting belt 31, a first Velcro 32, a second Velcro 33 and a connector 34. The flexible connecting belt 31 is connected to the first protective shell 22 through the connector 34. The first Velcro 32 and the flexible connecting belt 31 are fixedly connected. The first Velcro 32 is provided with a second Velcro 33, and the second Velcro 33 is fixedly connected to the limiting groove of the second protective shell 23.

[0040] Specifically, the flexible connecting belts 31 are symmetrically distributed on the upper and lower sides of the first protective shell 22 , and limiting grooves adapted to the second Velcro 33 are processed in the second protective shell 23 , and the first Velcro 32 and the second Velcro 33 correspond to each other.

[0041] In some embodiments, as Figure 5As shown, the connecting member 34 includes a pressing plate 341 and a positioning pin 342 . The pressing plate 341 and the flexible connecting belt 31 are arranged in parallel. The pressing plate 341 is connected to the first protective shell 22 through the positioning pin 342 . The flexible connecting belt 31 is located between the pressing plate 341 and the first protective shell 22 .

[0042] Specifically, the pressing plate 341 is used to fix the use position of the flexible connecting belt 31 . The pressing plate 341 and the positioning pin 342 are designed to be detachable, which facilitates the replacement of the flexible connecting belt 31 .

[0043] In some embodiments, as Figure 1 As shown, the positioning pins 342 are evenly distributed along the pressing plate 341 . The provision of multiple positioning pins 342 is used to increase the connection strength between the pressing plate 341 and the first protective shell 22 .

[0044] Specifically, the number of the positioning pins 342 is selected according to usage requirements, and the positioning pins 342 are used to increase the connection strength between the pressing plate 341 and the first protective shell 22 .

[0045] In some embodiments, as Figure 6 As shown, the flexible connecting belt 31 is made of polyester fiber non-woven fabric.

[0046] Polyester fiber non-woven fabric is a non-woven fabric produced with polyester fiber (PET) as the main raw material. Polyester fiber non-woven fabric has the characteristics of insect resistance, wear resistance, and UV resistance.

[0047] In some embodiments, as Figure 3 As shown, the heat-insulating sleeve 21 is made of glass fiber heat-insulating cotton material.

[0048] Glass fiber insulation wool is an inorganic non-metallic material with excellent performance. Its main characteristics include low thermal conductivity, good sound absorption, high tensile strength and high temperature resistance.

[0049] In some embodiments, as Figure 2 As shown, the first protective shell 22 is provided with a clamping plate 221 , and a side of the clamping plate 221 close to the heat-insulating sleeve 21 is processed with stripes.

[0050] Specifically, three card plates 221 are provided, and the card plates 221 are evenly distributed along the first protective shell 22 (the number of card plates 221 used is not specifically limited). Strip patterns are processed on the card plates 221 to increase the friction between the card plates 221 and the insulation sleeve 21 to prevent the first protective shell 22 from moving on the outer wall of the insulation sleeve 21.

[0051] In some embodiments, as Figure 2 As shown, an adhesive tape 211 is provided on the outer periphery of the thermal insulation sleeve 21 , and the adhesive tape 211 is used to bundle the thermal insulation sleeve 21 .

[0052] Exemplarily, the tape 211 is a waterproof tape, and the tape 211 is used to bundle the opening of the thermal insulation sleeve 21 to increase the connection strength between the thermal insulation sleeve 21 and the guide pipe body 1.

[0053] In some embodiments, as Figure 3 As shown, both ends of the guide pipe body 1 are fixedly connected with flanges 11, and an annular groove is processed on the flange 11.

[0054] The flange 11 is used for connecting the guide pipe body 1 , and the annular groove on the flange 11 is used for installing a sealing gasket to improve the sealing performance of the connection between adjacent guide pipe bodies 1 .

[0055] The working principle of this application is described below with a preferred embodiment:

[0056] The open insulation sleeve 21 is put on the outer periphery of the guide pipe body 1, and then the open insulation sleeve 21 is bundled with tape 211, and then the first protective shell 22 is put on the outer wall of the insulation sleeve 21, and the second protective shell 23 and the first protective shell 22 are connected through the plug-in plate 24. The friction between the plug-in plate 24 and the limiting groove of the first protective shell 22 and the friction between the card plate 221 and the insulation sleeve 21 are used to preliminarily connect the first protective shell 22 and the second protective shell 23. The first protective shell 22 and the second protective shell 23 are both processed with cavity structures. The flexible connecting belt 31 is then pushed to drive the first Velcro 32 and the second Velcro 33 to bond, and the flexible connecting belt 31 is used to seal the joint between the second protective shell 23 and the first protective shell 22 to increase the sealing performance of the joint between the first protective shell 22 and the second protective shell 23. The positioning pin 342 and the pressure plate 341 are rotated to separate, and the flexible connecting belt 31 and the first protective shell 22 are disassembled, so that the flexible connecting belt 31 can be replaced.

[0057] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents.
