Each pair of installation sleeves 14 are bolted. A positioning groove 15 is provided at the middle position of the installation sleeve 14. The positioning blocks 12 are located in the positioning grooves 15 of the installation sleeve 14. Tape grooves 16 are provided on the inner sides of the installation sleeves 14.
[0027] Both the first mounting shell 2 and the second mounting shell 3 are semi-circular ring-shaped shells. Filling holes are provided on both the left and right sides of the first mounting shell 2 and the second mounting shell 3. The thickness of the sealing cover 10 is the same as that of the first mounting shell 2 and the second mounting shell 3. The polyurethane filling layer 11 can be sealed in the first mounting shell 2 and the second mounting shell 3 through the sealing cover 10; both the first docking plate 4 and the second docking plate 8 are bent plates, both the first docking cloth 5 and the second docking cloth 7 are bent aluminum foil cloths. The first docking plate 4 is attached to the second docking cloth 7, and the first docking cloth 5 is attached to the second docking plate 8. Both the first inner lining layer 6 and the second inner lining layer 9 are bent aluminum foil cloths. The first inner lining layer 6 and the second inner lining layer 9 can prevent the polyurethane filling layer 11 from adhering to the pipe body 1; the positioning blocks 12 are all rectangular blocks, and the positioning blocks 12 are all aligned with the edges of the first mounting shell 2 or the second mounting shell 3. The positioning grooves 15 are all rectangular grooves.

The positioning grooves 15 can limit the positioning blocks 12; the mounting sleeves 14 are all semi-circular ring-shaped structures. Bolt connection holes are provided on both the upper and lower sides of the mounting sleeves 14. The tape grooves 16 of the mounting sleeves 14 are attached to the waterproof tapes 13. The mounting sleeves 14 can lock the first mounting shell 2 and the second mounting shell 3.
[0028] Workflow: The first docking plate 4 and the second docking plate 8 of this device are both bent plates, and the first docking cloth 5 and the second docking cloth 7 are both bent aluminum foil cloths. The first mounting shell 2, the first docking plate 4, the first docking cloth 5, the first inner lining layer 6, and a pair of sealing caps 10 of this device can form a sealed space. The second mounting shell 3, the second docking cloth 7, the second docking plate 8, the second inner lining layer 9, and a pair of sealing caps 10 of this device can form a sealed space. The weights of the first mounting shell 2, the second mounting shell 3, the first docking plate 4, and the second docking plate 8 of this device are all relatively small. The above are all prior arts. Before using this device, select the first mounting shell 2 and the second mounting shell 3 with appropriate sizes according to the diameter of the pipeline body 1, so that the distance between each pair of first docking plates 4 and the distance between each pair of second docking plates 8 are both equal to the outer diameter of the pipeline body 1. When using this device, sleeve the first mounting shell 2 and the second mounting shell 3 on both sides of the pipeline body 1, make the first mounting shell 2 and the second mounting shell 3 engage, and paste the waterproof tape 13 at the joint of the first mounting shell 2 and the second mounting shell 3, which can prevent rainwater or other liquids from seeping into the interior of this device from the joint of the first mounting shell 2 and the second mounting shell 3. At this time, the circular shell formed by the first mounting shell 2 and the second mounting shell 3 is sleeved on the outside of the pipeline body 1. Remove the sealing caps 10 on the sides of the first mounting shell 2 and the second mounting shell 3 respectively, and fill the interior of the first mounting shell 2 and the second mounting shell 3 with polyurethane foam. Polyurethane has good heat insulation performance and can solidify inside the first mounting shell 2 and the second mounting shell 3 to form a polyurethane filling layer 11. Moreover, the polyurethane filling layer 11 can lift the first docking cloth 5, the first inner lining layer 6, the second docking cloth 7, and the second inner lining layer 9, so that the first docking cloth 5 and the second docking plate 8 are closely attached, the second docking cloth 7 and the first docking plate 4 are closely attached, and the first inner lining layer 6 and the second inner lining layer 9 and the outer wall of the pipeline body 1 are closely attached. The first docking cloth 5, the first inner lining layer 6, the second docking cloth 7, and the second inner lining layer 9 are all made of aluminum foil cloth, which can prevent fire and water and have a certain damping. The first inner lining layer 6 and the second inner lining layer 9 are attached to the outside of the pipeline body 1 and will not slide. Reinstall the sealing caps 10. Repeating the above steps can sleeve multiple groups of the first mounting shell 2 and the second mounting shell 3 on the outside of the pipeline body 1. Then, sleeve the paired mounting sleeves 14 on the ends of the first mounting shell 2 and the second mounting shell 3, so that the positioning blocks 12 at the ends of two adjacent first mounting shells 2 or second mounting shells 3 are attached and pass through the positioning grooves 15 of the mounting sleeves 14. The positioning blocks 12 can be limited through the positioning grooves 15, and a pair of mounting sleeves 14 are fixedly connected by bolts. The tape grooves 16 of the mounting sleeves 14 are attached to the waterproof tape 13. Multiple groups of the first mounting shell 2 and the second mounting shell 3 can be docked and fixed through the mounting sleeves 14 to form a detachable heat insulation sleeve;The device can enable the polyurethane filling layer 11 to automatically solidify into a shape that perfectly matches the outer wall of the pipeline body 1 through the soft first inner lining layer 6 and the second inner lining layer 9. When the polyurethane filling layer 11 is filled, it can make the first docking cloth 5 and the second docking plate 8 fit tightly, and make the second docking cloth 7 and the first docking plate 4 fit tightly. Through the bent first docking plate 4 and the second docking plate 8, it can ensure that the docking part of the first installation shell 2 and the second installation shell 3 also has good heat preservation performance. The device pastes the first installation shell 2 and the second installation shell 3 together through the waterproof tape 13, and locks the first installation shell 2 and the second installation shell 3 through the installation sleeve 14. It can be disassembled and assembled repeatedly for many times, and the operation is relatively convenient, and the maintenance cost is relatively low.
