[0026] Example

[0027] The sealing connection device for the polyurethane insulation material cold-insulating pipe provided in this embodiment is as follows: Figures 1-5 As shown, it includes: a connecting mechanism and a conveying mechanism.

[0028] The connecting mechanism includes a first connecting pipe 1, a second connecting pipe 2, and a central pipe 3. One end of the first connecting pipe 1 is connected to the central pipe 3, and the other end of the central pipe 3 is connected to the second connecting pipe 2. A protective component is provided at the connection point between the central pipe 3 and the first connecting pipe 1 and the second connecting pipe 2. The protective component includes a first ring 4, a second ring 5, and a connecting rod 6. The first ring 4 is fitted onto the surface of the connection point between the central pipe 3 and the first connecting pipe 1, and the second ring 5 is fitted onto the surface of the connection point between the central pipe 3 and the second connecting pipe 2. Connecting rods 6 are evenly inserted between the surfaces of the first ring 4 and the second ring 5. Nuts are screwed into the connection points between the connecting rod 6 and the first ring 4 and the second ring 5. By using the connecting rod 6 structure to cooperate with the nuts for tightening, the connecting rod 6 can be effectively fixed to the first ring 4 and the second ring 5, thereby strengthening the connection stability between the first connecting pipe 1, the second connecting pipe 2, and the central pipe 3.

[0029] The conveying mechanism includes a mounting frame 7, a conveying pipe 8, and a mounting assembly 9. The mounting frame 7 houses the conveying pipe 8, and its surface is fixedly connected to the central pipe 3 via the mounting assembly 9. The mounting assembly 9 includes a mounting block 91 and an insert block 92. The mounting block 91 is bonded to the surface of the mounting frame 7, and an insert block 92 is integrally formed on one side of the mounting block 91. Mounting edges 31 are evenly arranged on the inner wall of the central pipe 3, and slots are provided on the mounting edges 31. The mounting block 91 is fixedly inserted into the slots via the insert block 92. The mounting assembly 9 provides good protection between the mounting frame 7 and the central pipe 3, and allows for sliding assembly and disassembly based on the insertion direction of the insert block 92 and the slot. This makes the overall movement smoother and easier to achieve, providing excellent protection and further ensuring the safety of the internal conveying pipe 8.

[0030] In the sealing connection device for polyurethane insulation material cold-insulated pipes using the above technical solution, the mounting frame 7 includes a base 71, a pressure-resistant layer 72, an insulation layer 73, an antifreeze layer 74, and an inner lining layer 75. The pressure-resistant layer 72 is laid on the surface of the base 71 and is connected to the inner walls of the first connecting pipe 1 and the second connecting pipe 2. The insulation layer 73 is laid on the inner side of the base 71, and the antifreeze layer 74 is laid on the inner side of the insulation layer 73. The inner wall of the antifreeze layer 74 is provided with the inner lining layer 75. The pressure-resistant layer 72 is an integrated structure made of steel sheet material, the insulation layer 73 is made of aluminum foil material, the antifreeze layer 74 is made of glass fiber material, and the inner lining layer 75 is made of waterproof fabric. These components work together to form a sufficient and good auxiliary protection effect, effectively ensuring the overall structure's protective performance. This allows the internal conveying pipe 8 to have good rigidity and strength, while also providing a certain degree of waterproof, antifreeze, and insulation effects, making it more suitable for polyurethane insulation material cold-insulated pipes.

[0031] In summary, the sealing connection device for polyurethane insulation material cold-insulating pipes provided in this embodiment has the following advantages:

[0032] In the specific working process, the central pipe 3 is inserted into each mounting block 91 on the mounting frame 7 through the mounting edge 31 structure on the inner wall to ensure its basic position is fixed. Then, the first connecting pipe 1 and the second connecting pipe 2 are installed to both ends of the central pipe 3. At this time, the connection between the central pipe 3 and the first connecting pipe 1 and the second connecting pipe 2 is respectively fitted with the first ring sleeve 4 and the second ring sleeve 5, thus completing the basic assembly work. This structure can ensure the overall safety of the internal conveying pipe 8 and has a good anti-freeze, heat preservation and sealing effect. When in use, the entire structure can be connected to the cold insulation pipe to be used. When disassembly is required, it is only necessary to remove the ring sleeve and the first connecting pipe 1 and the second connecting pipe 2 on both sides in sequence, and slide the central pipe 3 out along the structural direction of the slot and the insertion block 92 to complete the disassembly, which is convenient for subsequent maintenance or repair.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model.
