[0002] Outer protective pipes are widely used in fields such as construction, petrochemical industry, and municipal construction. Especially in a direct-buried insulating pipe system, the outer protective pipe plays a role in protecting the internal pipe from soil pressure, moisture, and chemical erosion. In addition, the outer protective pipe can effectively prevent water and moisture, and has good integrity and aesthetics. Among them, an insulating pipe is an adiabatic pipe used for transporting liquids, gases, and other media, and is widely used in fields such as petroleum, chemical industry, aerospace, military, central heating, central air conditioning, and municipal engineering. The main function of the insulating pipe is to reduce the loss of heat during transportation and keep the medium within a suitable temperature range.

[0003] During the repair process of the outer protective pipe, an insulating pipe is required. At present, although the existing insulating pipes have good heat insulation effects.

[0004] However, most of the existing insulating pipes currently do not have a protective structure, and their overall structure is relatively fragile. As a result, during long-term use, the middle section or both ends of the insulating pipe are prone to breakage, which seriously affects the heat insulation effect of the insulating pipe and is not conducive to long-term use. Therefore, an energy-saving and environmental protection heating insulating pipe for repairing an outer protective pipe is proposed to solve the problems raised above. Content of the Utility Model

[0005] In view of the deficiencies of the prior art, the utility model provides an energy-saving and environmental protection heating insulating pipe for repairing an outer protective pipe, which solves the problems that most of the existing insulating pipes do not have a protective structure, their overall structure is relatively fragile, and during long-term use, the middle section or both ends of the insulating pipe are prone to breakage, which seriously affects the heat insulation effect of the insulating pipe and is not conducive to long-term use.

[0006] To achieve the above object, the utility model provides the following technical solution: An energy-saving and environmental protection heating insulating pipe for repairing an outer protective pipe, comprising a main insulating pipe body, and a protective structure is arranged outside the main insulating pipe body;

[0007] The protective structure includes a protective sleeve fixedly connected to the middle section of the main insulating pipe body. A partition strip is fixedly connected to the outer surface of the protective sleeve. Slide grooves are formed on the left and right sides of the main insulating pipe body. An arc-shaped protective plate is slidably connected to the inner side of the slide groove. Connection plates are arranged on the left and right sides of the main insulating pipe body. Threaded positioning holes with the same inner diameter size are formed on the outer surfaces of the main insulating pipe body, the arc-shaped protective plate, and the connection plates. A positioning bolt is threadedly connected to the inner side of the threaded positioning hole.

[0008] Further, the number of the arc-shaped protection plates and the connecting plates is the same, and both are four.

[0009] Further, the number of the partition strips is eight, and they are evenly distributed in a ring shape. The shape of the connecting plate is L-shaped.

[0010] Further, a first pipe sleeve is fixedly connected to the inner side of the main body of the heat preservation pipe. The first pipe sleeve is made of rock wool.

[0011] Further, a second pipe sleeve is fixedly connected to the inner side of the first pipe shell. The second pipe sleeve is made of ceramics.

[0012] Further, a first docking pipe is fixedly connected to the left side of the main body of the heat preservation pipe, and a second docking pipe is fixedly connected to the right side of the main body of the heat preservation pipe.

[0013] Further, a slot is formed in the outer side of the first docking pipe, and a plug rod is fixedly connected to the outer side of the second docking pipe.

[0014] Compared with the prior art, the technical solution of the present application has the following beneficial effects:

[0015] 1. For the energy-saving and environmental protection heat supply and heat preservation pipe for outer pipe repair, by setting the protection structure, during use, the protection sleeve and the partition strips in the middle section of the main body of the heat preservation pipe achieve the effect of middle section protection. When an external object is about to impact the main body of the heat preservation pipe, the eight partition strips evenly distributed in a ring shape can well isolate the external object, thereby preventing the external object from directly contacting the main body of the heat preservation pipe, and then effectively protecting it. At the same time, the arc-shaped protection plates distributed at the left and right ends of the main body of the heat preservation pipe achieve the effect of two-end protection, which can prevent the left and right ends of the main body of the heat preservation pipe from being damaged due to external pressure. Moreover, the arc-shaped protection plates are easy to replace. When the arc-shaped protection plate is damaged, the staff only needs to counterclockwise screw out all the positioning bolts from the threaded positioning holes to release the fixation of the arc-shaped protection plate. At this time, pulling the arc-shaped protection plate outwards can extract it for replacement. Therefore, compared with the existing heat preservation pipes, it realizes a better protection function, thereby enhancing its overall strength, effectively avoiding the situation that the middle section or both ends of the heat preservation pipe are prone to breakage during long-term use, and then ensuring the heat preservation effect of the heat preservation pipe, having a higher service life, and being more conducive to long-term use.

Specific implementation manner

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1 to 3 , a heat preservation pipe for repairing the outer protection pipe and saving energy and protecting the environment in this embodiment, includes a main body 1 of the heat preservation pipe, and a protective structure is arranged outside the main body 1 of the heat preservation pipe;

[0023] The protective structure includes a protective sleeve 2 fixedly connected to the middle section of the main body 1 of the heat preservation pipe. A partition strip 3 is fixedly connected to the outer surface of the protective sleeve 2. Sliding grooves 4 are opened on the left and right sides of the main body 1 of the heat preservation pipe. An arc-shaped protective plate 5 is slidably connected to the inner side of the sliding groove 4. Connecting plates 6 are arranged on the left and right sides of the main body 1 of the heat preservation pipe. Threaded positioning holes 7 with the same inner diameter size are opened on the outer surfaces of the main body 1 of the heat preservation pipe, the arc-shaped protective plate 5, and the connecting plate 6. A positioning bolt 8 is threadedly connected to the inner side of the threaded positioning hole 7. During use, the protective sleeve 2 and the partition strip 3 located in the middle section of the main body 1 of the heat preservation pipe achieve the effect of middle section protection. When an external object is about to hit the main body 1 of the heat preservation pipe, the eight partition strips 3 distributed at equal intervals in a ring shape can well isolate the external object, thereby avoiding direct contact between the external object and the main body 1 of the heat preservation pipe, and then effectively protecting it.

[0024] At the same time, the arc-shaped protective plates 5 distributed at the left and right ends of the main body 1 of the heat preservation pipe achieve the effect of protecting the two ends, and can prevent the left and right ends of the main body 1 of the heat preservation pipe from being damaged due to external pressure. Moreover, the arc-shaped protective plate 5 is easy to replace. When the arc-shaped protective plate 5 is damaged, the staff only needs to counterclockwise screw out all the positioning bolts 8 from the threaded positioning hole 7 to release the fixation of the arc-shaped protective plate 5. At this time, pulling the arc-shaped protective plate 5 outwards can extract it for replacement.

[0025] Furthermore, compared with the existing insulation pipes, it achieves better protection functions, thereby strengthening its overall strength. In the case of long-term use, it effectively avoids the situation that the middle section or both ends of the insulation pipe are prone to breakage, thus ensuring the insulation effect of the insulation pipe, having a high service life, and being more conducive to long-term use.

[0026] It should be noted that the number of arc-shaped protection plates 5 and connecting plates 6 is the same, both being four, the number of partition bars 3 is eight, and they are evenly distributed in a ring shape. The shape of the connecting plate 6 is L-shaped.

[0027] Among them, a first pipe sleeve 9 is fixedly connected to the inner side of the insulation pipe main body 1. The first pipe sleeve is made of rock wool. A second pipe sleeve 10 is fixedly connected to the inner side of the first pipe shell 9. The second pipe sleeve 10 is made of ceramics.

[0028] The first pipe sleeve 9 made of rock wool and the second pipe sleeve 10 made of ceramics achieve the functions of heat preservation and anti-corrosion, thereby effectively enhancing the functionality of the insulation pipe main body 1.

[0029] In addition, a first docking pipe 11 is fixedly connected to the left side of the insulation pipe main body 1, a second docking pipe 12 is fixedly connected to the right side of the insulation pipe main body 1. A slot 13 is provided on the outer side of the first docking pipe 11, and a plug rod 14 is fixedly connected to the outer side of the second docking pipe 12. Through the first docking pipe 11, the second docking pipe 12, the slot 13 and the plug rod 14, it is convenient for the staff to dock multiple insulation pipe main bodies 1 by splicing for use, thereby improving the practicality.

[0030] The working principle of the above embodiment is as follows:

[0031] When in use, the protection sleeve 2 and the partition bars 3 in the middle section of the insulation pipe main body 1 achieve the effect of middle section protection. When an external object is about to impact the insulation pipe main body 1, the eight partition bars 3 evenly distributed in a ring shape can well isolate the external object, thereby preventing the external object from directly contacting the insulation pipe main body 1, and then effectively protecting it. At the same time, the arc-shaped protection plates 5 distributed at both ends of the insulation pipe main body 1 achieve the effect of both ends protection, which can prevent the left and right ends of the insulation pipe main body 1 from being damaged due to external pressure. And the arc-shaped protection plates 5 are easy to replace. When the arc-shaped protection plate 5 is damaged, the staff only needs to counterclockwise screw out all the positioning bolts 8 from the threaded positioning holes 7 to release the fixation of the arc-shaped protection plate 5. At this time, pulling the arc-shaped protection plate 5 outwards can extract it for replacement. In addition, the first docking pipe 11, the second docking pipe 12, the slot 13 and the plug rod 14 can facilitate the staff to dock multiple insulation pipe main bodies 1 by splicing for use, which is relatively convenient.
