[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0020] Traditional thermal pipeline insulation devices are inconvenient to use during construction and splicing. The insulation layer and protective shell need to be cut and aligned on site, which requires high technical skills from workers and the interface treatment is relatively complicated. This results in low overall construction efficiency and high labor intensity for workers, thus causing inconvenience to the workers.

Through the cooperation of a first heat preservation pipe, a second heat preservation pipe, a third heat preservation pipe, a fourth heat preservation pipe, a heat insulation pad, and a cavity, multiple components can be modularly and quickly spliced ​​together. The interface positions are regular, which can effectively ensure the quality of splicing and eliminate the need for additional cutting. This greatly reduces the workload of workers and improves the overall work efficiency, thus making it convenient for workers to use.

[0022] Example 1: By Figure 1 , 2 As can be seen from 3, 4, 5 and 6, a heat insulation device for a heating pipe network includes a pipe body 1, a first heat insulation pipe 2 sleeved on the upper part of the outer wall of the pipe body 1, a second heat insulation pipe 3 fixedly connected to the bottom of the first heat insulation pipe 2 by bolts, and the outer wall of the second heat insulation pipe 3 sleeved on the lower part of the outer wall of the pipe body 1, a third heat insulation pipe 4 fixedly connected to both sides of the outer wall of the first heat insulation pipe 2 by bolts, and the inner walls of the two third heat insulation pipes 4 sleeved on the upper part of the outer wall of the pipe body 1, a fourth heat insulation pipe 5 fixedly connected to the bottom of the two third heat insulation pipes 4 by bolts, and the inner walls of the two fourth heat insulation pipes 5 sleeved on the lower part of the outer wall of the pipe body 1, and the sides of the two fourth heat insulation pipes 5 that are close to each other are fixedly connected to both sides of the second heat insulation pipe 3 by bolts.

[0023] In the specific implementation process, it is worth noting that there are no restrictions on the materials of the first insulation pipe 2, the second insulation pipe 3, the third insulation pipe 4 and the fourth insulation pipe 5, as long as they meet the usage requirements. By splicing and assembling the first insulation pipe 2, the second insulation pipe 3, the third insulation pipe 4 and the fourth insulation pipe 5, the pipe body 1 can be isolated and protected.

[0024] Furthermore, the inner walls of the first insulation pipe 2, the second insulation pipe 3, the third insulation pipe 4 and the fourth insulation pipe 5 are all fixedly connected with heat insulation pads 6, and the interiors of the first insulation pipe 2, the second insulation pipe 3, the third insulation pipe 4 and the fourth insulation pipe 5 are all machined with cavities 8.

[0025] In the specific implementation process, it is worth noting that the material of the heat insulation pad 6 can be polyurethane foam, rock wool, etc. There are no restrictions on the specific material, as long as it meets the actual use requirements. The design of the cavity 8 can reduce the heat conduction efficiency in order to play a role in heat preservation.

[0026] Furthermore, the bottom sides of the two first insulation pipes 2 and the third insulation pipe 4 are fixedly connected with plug strips 9, and the outer walls of multiple plug strips 9 are respectively inserted into the top grooves of the two second insulation pipes 3 and the fourth insulation pipe 5.

[0027] In the specific implementation process, it is worth noting that the plug strip 9 can assist the staff in splicing and assembling;

[0028] Furthermore, friction plates 7 are fixedly connected to the inner walls of the two third insulation pipes 4 and the fourth insulation pipe 5, and the inner walls of multiple friction plates 7 are pressed against the outer wall of the pipe body 1. The outer walls of multiple friction plates 7 on the side closer to the first insulation pipe 2 and the second insulation pipe 3 are respectively attached to the inner walls of the first insulation pipe 2 and the second insulation pipe 3.

[0029] In the specific implementation process, it is worth noting that the friction plate 7 can increase the friction between the third insulation pipe 4 and the fourth insulation pipe 5 and the pipe body 1, thereby improving the stability during installation.

[0030] Furthermore, sealing gaskets are fixedly connected to the joints between the first insulation pipe 2, the second insulation pipe 3, the third insulation pipe 4, and the fourth insulation pipe 5.

[0031] In the specific implementation process, it is worth noting that the design of the sealing gasket can improve the sealing performance when the various components are spliced ​​together, so as to prevent external water from entering the interior of the device and thus affecting the thermal insulation performance. There are no restrictions on the material of the sealing gasket, as long as it meets the usage requirements.

[0032] Specifically, when using the insulation device of this heating network, the workers sequentially place the first insulation pipe 2 and the second insulation pipe 3 onto the outer wall of the pipe body 1, and then use bolts to install and fix the first insulation pipe 2 and the second insulation pipe 3. Next, the third insulation pipe 4 and the fourth insulation pipe 5 are placed onto the outer wall of the pipe body 1, and then the third insulation pipe 4 and the fourth insulation pipe 5 are pushed. Then, the third insulation pipe 4 and the fourth insulation pipe 5 are placed on the outside of the first insulation pipe 2 and the second insulation pipe 3, and then the third insulation pipe 4 and the fourth insulation pipe 5 are connected and fixed with bolts. Finally, the third insulation pipe 4, the first insulation pipe 2 and the fourth insulation pipe 5 and the second insulation pipe 3 are installed and fixed with threads. At this time, the splicing work is completed.
