It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0024] Example: Figure 1-5 As shown, a heat-insulating pipe for pipe protection comprises a main pipe 1, an outer wall of the main pipe 1 is provided with a heat-insulating layer 2, a plurality of mounting rings 3 are evenly distributed on the heat-insulating layer 2, the mounting ring 3 comprises an arc-shaped plate 8, two arc-shaped plates 8 are symmetrically provided, a flat plate 9 is fixedly connected to the facing sides of the two arc-shaped plates 8, two adjacent flat plates 9 are connected by a first bolt 10, a nut 11 is threadedly connected to the first bolt 10, and the fixing and mounting operation of the protection structure can be facilitated;

[0025] A plurality of movable tubes 4 are evenly distributed and movably connected on the outer wall of the mounting ring 3, and a threaded tube 5 is movably connected inside each movable tube 4. A first spring 6 is fixedly connected to one end of the threaded tube 5 located in the inner cavity of the movable tube 4, and the other end of the first spring 6 is fixedly connected to the inner wall of the movable tube 4. A protective plate 7 is installed at one end of the threaded tube 5 away from the main tube 1, and the protective plate 7 can reduce the damage to the insulation pipe caused by external environmental factors and impact, thereby improving the protection of the insulation pipe;

[0026] Among them, the movable tube 4 is fixedly connected to the end away from the protective plate 7 with a rotating shaft 14, and both ends of the rotating shaft 14 are movably connected to the side plates 15, and the side plates 15 are fixedly connected to the mounting ring 3. A second spring 16 is sleeved on the rotating shaft 14, and one end of the second spring 16 is fixedly connected to the movable tube 4, and the other end of the second spring 16 is fixedly connected to the side plate 15, so that the protective plate 7 can be reset, which is convenient for protection.

[0027] A through hole 12 is provided on the side wall of the protective plate 7, and a second bolt 13 is inserted into the through hole 12. The second bolt 13 is threadedly connected to the threaded pipe 5, which can facilitate the fixing and installation operation of the protective plate 7;

[0028] The protective plate 7 is arranged in an arc shape, and slots 17 are opened on the two side walls of the protective plate 7. Insert plates 18 are fixedly connected to the other two side walls of the protective plate 7. The insert plates 18 and the slots 17 are matched with each other. Four protective plates 7 are distributed in a ring array on the same cross section. The adjacent insert plates 18 and slots 17 on the four protective plates 7 are plugged into each other, which improves the reliability between the protective plates 7 and has a good protective effect.

[0029] Working principle: When the device of the utility model is used, the mounting ring 3 is firstly fixedly installed at a suitable position on the outer wall of the insulation layer 2 according to actual needs, and the arc plates 8 are respectively placed at suitable positions on the outer wall of the insulation layer 2. The two flat plates 9 are fixedly installed by the first bolt 10, so that the arc plates 8 are fixedly installed on the insulation layer 2. Then, the through hole 12 on the protective plate 7 is aligned with the threaded tube 5, and the second bolt 13 is inserted into the through hole 12. The fixed installation operation between the protective plate 7 and the threaded tube 5 can be achieved by the action of the second bolt 13, and then the plug-in connection between the plug plate 18 and the slot 17 between the protective plates 7 is made. The installation operation of the protective plate 7 on the insulation layer 2 can be realized to complete the protection of the insulation layer 2. The protective plate 7 can be used to protect against external environmental factors and reduce the damage to the insulation layer 2 caused by environmental factors. When the protective plate 7 is subjected to external impact, the protective plate 7 drives the threaded tube 5 to move. The threaded tube 5 compresses the first spring 6 and drives the movable tube 4 thereon to rotate around the rotating shaft 14 through the adjacent protective plate 7, deforming the second spring 16. This can effectively prevent external impact force from directly acting on the insulation layer 2, and the protective plate 7 can be reset under the action of the first spring 6 and the second spring 16, thereby improving the protection of the insulation pipe.
