[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] An embodiment provided by the utility model: Figure 1 As shown, an energy-saving heat preservation device for a heating pipe comprises a heating pipe 1, a heat preservation shell 2, a hollow layer 3, a pipe connection pad 4, a shell fixing part 5 and an inflation head 6.

[0027] like Figure 2 and Figure 3 As shown, two groups of heat-insulating outer shells 2 are provided, which are respectively located on both sides of the heating pipe 1 , and a hollow layer 3 and a pipe connecting pad 4 are also provided between the heat-insulating outer shell 2 and the heating pipe 1 .

[0028] like Figure 3As shown, a hollow layer 3 is provided on the inner side of the heat-insulating outer shell 2, an inflatable bag 31 is provided inside the hollow layer 3, and an inflatable head 6 is provided on the surface of the heat-insulating outer shell 2, and the inflatable head 6 passes through the slots provided between the heat-insulating outer shell 2 and the hollow layer 3 and is connected to the inflatable bag 31. The insulating gas is pumped into the inflatable bag 31 in the hollow layer 3 from the inflatable head 6, and the inflatable bag 31 expands to fill the entire hollow layer 3, wherein the insulating gas can be a rare gas or an inert gas, etc. The insulating gas has a low thermal conductivity, which can effectively reduce the conduction loss of heat through the pipe insulation layer, help reduce the impact of external temperature changes on the temperature of the insulation material, and maintain the stability of the temperature inside the pipe; and the insulating gas is filled in the hollow layer 3 to form an insulating layer inside the heat-insulating outer shell 2, further reducing heat conduction and enhancing the insulation effect of the overall structure.

[0029] like Figure 3 and Figure 4 As shown, a pipe connection pad 4 is arranged on the inner side of the hollow layer 3. The pipe connection pad 4 is made of flexible material. When the heat-insulating outer shell 2 is installed on the heating pipe 1, two sets of heat-insulating outer shells 2 are fixed together, which will squeeze the internal pipe connection pad 4 to fit tightly with the heating pipe 1, thereby ensuring that the installed heat-insulating outer shell 2 is firmly fixed to the heating pipe 1.

[0030] like Figure 4 As shown, the top and bottom of the heat-insulating shell 2 are respectively provided with protruding parts with grooves, and the protruding parts with grooves of the heat-insulating shell 2 are provided with magnetic strips 22 on the fitting surface thereof, and the positions of the magnetic strips 22 of the two sets of heat-insulating shells 2 correspond to each other. When installing the device, the two sets of heat-insulating shells 2 are put on the heating pipe 1 and fit together, and the magnetic strips 22 on the heat-insulating shell 2 connect the two sets of heat-insulating shells 2 together, replacing the manual fitting operation, facilitating the next step of fixing operation, simplifying the installation steps, and improving the installation work efficiency.

[0031] like Figure 5 and Figure 6 As shown, the protruding parts with grooves of one group of heat-insulating shells 2 are provided with protruding parts 212 on their fitting surfaces, and the protruding parts with grooves of the other group of heat-insulating shells 2 are provided with grooves 213, and the protruding parts 212 of the two groups of heat-insulating shells 2 match the grooves 213. When the two groups of heat-insulating shells 2 are fitted together, the protruding parts 212 of one group are plugged into the grooves 213 of the other group, thereby enhancing the fixation between the two groups of heat-insulating shells 2, making them less likely to be misaligned, and ensuring that the positions of the two groups of heat-insulating shells 2 are completely aligned when installed and fixed.

[0032] like Figure 1 or Figure 7As shown, after the two sets of heat-insulating shells 2 on both sides of the heating pipe 1 are fitted and connected, the protruding parts with grooves are fixed together by the shell fixing parts 5. The shell fixing parts 5 are U-shaped, and a sealing strip 51 is arranged inside the shell fixing parts 5. The sealing strip 51 is tightly fitted with the protruding parts with grooves. The shell fixing parts 5 fix the two sets of heat-insulating shells 2 so that they are wrapped around the heating pipe 1 and are not easy to fall off. The sealing strip 51 seals the gap between the two sets of heat-insulating shells 2, reduces the heat dissipation of the heating pipe 1, ensures the heat preservation function, and achieves energy-saving effects.

[0033] like Figure 2 As shown, one end of the insulation shell 2 is a protruding head 211, and the outer diameter of the protruding head 211 of the insulation shell 2 matches the inner diameter of the tail connected to the insulation shell 2. The protruding head 211 includes a rubber strip 2111, and the rubber strip 2111 is located between the outer side of the protruding head 211 of the insulation shell 2 and the inner side of the tail of the insulation shell 2. When installing another adjacent group of insulation shells 2 for the heating pipe 1, the inner side of the tail of the new group of insulation shells 2 is just spliced ​​with the protruding head 211 of the old group, and the protruding head 211 of the old group of insulation shells 2 abuts against the hollow layer 3 of the new group of insulation shells 2 and the pipe connection pad 4. The connection of the two groups of insulation shells 2 has an overlapping part, and the overlapping part is sealed by the rubber strip 211, so that the insulation shells 2 at different positions outside the heating pipe 1 are continuous and sealed, further reducing the heat loss of the heating pipe 1 and achieving energy saving.
