Heating pipes are usually laid outdoors, and for heat preservation, thick insulation materials are wrapped around the outside of the pipes. Most of the existing heating pipes are placed outdoors, so most of the insulation materials are also exposed to the outdoor environment, which is extremely susceptible to external environmental factors and human factors, resulting in damage, which in turn reduces the heating efficiency of the central heating pipes. Summary of the invention

[0003] In view of this, the purpose of the present invention is to provide a heating pipeline protection structure to solve the problems pointed out in the above background technology.

[0004] In order to achieve the above utility model purpose, the technical solution adopted is as follows:

[0006] As a further improvement of the present invention, the curved pipe section is a flexible bellows, which has excellent anti-deformation capabilities such as expansion and contraction and bending, and can effectively absorb the deformation caused by the axial thermal displacement of the heating pipeline without damaging the protective shell.

[0007] As a further improvement of the utility model, a first annular connecting plate for connecting with the transition section is fixed on the straight pipe section, a second annular connecting plate and a third annular connecting plate are respectively fixed at both ends of the transition section, and a fourth annular connecting plate is fixed at both ends of the curved pipe section, the first annular connecting plate is fixedly connected to the second annular connecting plate, and the third annular connecting plate is fixedly connected to the fourth annular connecting plate.

[0008] As a further improvement of the utility model, the thermal insulation layer includes a first filling layer and a second filling layer which are sequentially arranged from the inside to the outside, which can ensure the thermal insulation effect and the protective effect on the heating pipe.

[0009] As a further improvement of the present invention, the first filling layer and the second filling layer are both made of high-temperature glass wool. The high-temperature glass wool can be used under high temperature conditions and can still achieve the functions of heat insulation and combustion prevention under high temperature without odor and without volatile or escaping any harmful components, so as to achieve the purpose of environmental protection.
