Description

Technical Field

[0001] The utility model relates to a prefabricated directly buried thermal insulation pipe with a protective structure, belonging to the field of prefabricated directly buried thermal insulation pipes. Background Art

[0002] In the existing pipeline engineering technology, prefabricated direct-buried insulated pipes are a key equipment widely used in heating, cooling and industrial pipeline transportation. Their performance and structure are directly related to the safe operation and service life of the pipelines. However, the existing prefabricated direct-buried insulated pipes have many shortcomings in structural strength, thermal insulation effect and waterproof function, which limits their performance in practical applications.

[0003] First, in terms of structural strength, the existing prefabricated direct-buried insulated pipes are often not stable enough in their internal support structures, which makes the pipes prone to deformation or even rupture when subjected to external pressure or soil displacement. This not only affects the normal operation of the pipeline, but may also lead to serious safety accidents. Secondly, in terms of thermal insulation effect, the existing thermal insulation materials often have high thermal conductivity or insufficient thickness of the insulation layer, resulting in large heat loss during transmission, and cannot meet the requirements of high efficiency and energy saving. This not only increases energy consumption, but also reduces the economic benefits of the pipeline system. Finally, in terms of waterproof function, the existing prefabricated direct-buried insulated pipes have poor waterproof effect, and moisture can easily penetrate into the insulation layer, resulting in a decrease in thermal insulation performance and even causing corrosion and damage to the pipeline.

DETAILED DESCRIPTION

[0023] 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.

[0024] See also Figure 1-3 A prefabricated direct-buried thermal insulation pipe with a protective structure comprises a base 1 and a protective pipe 2. The upper surface of the base 1 is provided with a reinforcing structure for increasing the structural strength.

[0025] Embodiment 1, as Figure 1 As shown, the reinforcement structure includes a movable opening 3 opened on the upper surface of the base 1, a mounting plate 4 slidably connected to the inner side of the movable opening 3, an elastic telescopic rod 5 fixedly connected to the bottom of the mounting plate 4, two support plates 6 fixedly connected to the upper surface of the base 1, a connecting plate 7 fixedly connected between the tops of the two support plates 6, a rubber pad 8 fixedly connected to the upper surface of the connecting plate 7, and a fixing plate 9 fixedly connected to the upper surface of the rubber pad 8.

[0026] The upper surface of the fixing plate 9 is provided with a waterproof component for waterproofing.

[0027] It should be noted that two mounting rods 10 are fixedly connected to the bottom of the protection tube 2, and the bottom ends of the mounting rods 10 are fixedly connected to the upper surface of the mounting plate 4. The outer side of the protection tube 2 is fixedly connected with an aerogel felt 11. The aerogel felt 11 is a new type of nanoporous thermal insulation material with a large number of nano-scale pores inside, which makes its thermal conductivity extremely low and has excellent thermal insulation performance. At the same time, the aerogel felt 11 also has excellent fire resistance and can meet higher safety requirements. The inner side of the protection tube 2 is fixedly connected with rock wool 12. The rock wool 12 has the characteristics of light weight, fire resistance, heat insulation, non-water absorption, and non-aging. In prefabricated direct-buried insulated pipes, they can be used as an important component of the insulation layer to improve the insulation effect and service life of the pipeline. The inner side of the rock wool 12 is fixedly connected with aluminum foil 13. The aluminum foil 13 has high reflectivity and can reflect the heat generated by the working steel pipe back to the insulation layer to reduce heat loss.

[0028] There are three elastic telescopic rods 5, and the three elastic telescopic rods 5 are fixedly connected to the inner bottom wall of the base 1. The mounting plate 4 is fixedly connected between the top ends of the piston rods of the three elastic telescopic rods 5. The two support plates 6 are respectively located on the left and right sides of the protective tube 2, and the right side wall of the left support plate 6 and the left side wall of the right support plate 6 are fixedly connected with silicone 14. The silicone material is soft, elastic, and resistant to high temperature and aging, thereby protecting the protective tube 2.

[0029] The waterproof assembly includes a water guide block 15 fixedly connected to the upper surface of the fixed plate 9, a container 16 fixedly connected to the left and right sides of the fixed plate 9 respectively, and a sponge 17 fixedly connected to the inner bottom wall of the container 16. The length and width of the water guide block 15 are respectively equal to the length and width of the fixed plate 9, and the cross-section of the water guide block 15 is an isosceles trapezoid as a whole.

[0030] Embodiment 2, as Figure 1 As shown, a waterproof coating, such as a polymer waterproof material, can be applied on the outer surface of the protective tube 2. This coating can effectively prevent moisture from penetrating into the insulation layer, thereby maintaining the dryness and thermal insulation performance of the pipeline. In addition, the protective tube 2 can be made of stainless steel, thereby improving the corrosion resistance of the protective tube 2.

[0031] The working principle of the above embodiment is:

[0032] When the top of the fixing plate 9 is subjected to pressure, the fixing plate 9 further transmits the pressure to the rubber pad 8. Since the rubber pad 8 has high elasticity, it can absorb and disperse the impact and pressure from the outside. When subjected to load, the rubber pad 8 will undergo elastic deformation to evenly distribute the pressure to a larger area, thereby reducing the pressure per unit area. Moreover, when the top of the protection tube 2 is subjected to pressure, the protection tube 2 presses the mounting plate 4 downward through the mounting rod 10, and the mounting plate 4 further presses the elastic telescopic rod 5. The deformation characteristics of the elastic telescopic rod 5 provide a buffer for the protection tube 2, thereby avoiding hard contact between the protection tube 2 and the pressure source.

[0033] When there is moisture above, the moisture will be guided to the inside of the container 16 through the inclined surface of the water guide block 15, and the moisture entering the container 16 will be absorbed by the sponge 17, thereby preventing the moisture from penetrating into the insulation layer, thereby achieving a waterproof effect.

[0034] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, an element defined by the sentence "comprises a ..." does not exclude the existence of other identical elements in the process, method, article or device including the element.

[0035] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
