[0032] Example

[0033] Reference Figure 1-Figure 3 , is a pre-installed insulation structure for pipelines disclosed in the utility model, the utility model includes: an insulation body, the insulation body is cylindrical, the insulation body is divided into two identical insulation structures, the two insulation structures are buckled on the outside of the pipeline 5; the two insulation structures are buckled through a connecting component, the connecting component includes an inner fixing ring 4 and a connecting plate 6, the inner fixing ring 4 is parallel to the buckling part of the insulation structure.

[0034] Specifically, the utility model can adopt a prefabricated insulation structure, and through the combination and installation of multiple insulation structures, the pipe 5 can be flexibly wrapped, and it is convenient to disassemble and assemble, and it is suitable for various situations. The length of a single insulation structure is fixed, and during on-site construction, according to the length of the pipe 5, all-round insulation of the pipe 5 is formed by splicing. The diameter of the insulation structure is made according to the outer diameter of the insulation pipe, and the length of the insulation structure can be arbitrarily selected according to the length of the pipe 5.

[0035] The purpose of the utility model is to solve the adverse effects of poor insulation effect and slow construction speed during the installation and construction of the heat-insulating and cold-insulating pipe 5. The utility model adopts a pre-installation method and an integrated finished product to centrally manufacture and install the outer protective plate 1, the insulation layer 2, the inner support parts, etc. off-site. Relying on the integrated overall design, while ensuring the insulation effect, it greatly speeds up the installation speed during on-site construction and has high economic benefits. The utility model promotes the development of the heat-insulating and cold-insulating pipe 5 system in the direction of integration and prefabrication, and forms a tightly integrated whole with the insulation layer 2 and the pipe 5 itself, thereby improving the insulation effect, reducing heat loss, and simplifying the construction process.

[0036] It is further configured as follows: a convex block and a concave block are provided at the buckling part of the thermal insulation structure, wherein when the two thermal insulation structures are buckled, the convex block of one thermal insulation structure is engaged with the concave block of the other thermal insulation structure.

[0037] Specifically, the buckling parts of the two insulation structures and the end-to-end joints of the insulation structures are provided with protrusions and depressions, and the insulation structures can be tightly connected together through the cooperation of the protrusions and depressions. The clamping design of the protrusions and depressions can ensure that the two insulation structures form a close contact when buckled, effectively preventing heat from leaking from the joints, thereby significantly improving the insulation effect. The clamping of the protrusions and depressions not only provides sealing, but also enhances the stability of the connection. This design makes the insulation structure difficult to separate or deform when subjected to external force or temperature changes, ensuring the long-term stability and reliability of the insulation system. By arranging protrusions and depressions at the buckling parts and the end-to-end joints, the insulation structure can adapt to pipes of different diameters and lengths 5. This design makes the insulation system more flexible and versatile, and can meet the needs of different projects and scenarios. The matching design of the protrusions and depressions makes the installation of the insulation structure simpler and faster. The construction personnel only need to clamp the protrusions and depressions of the two insulation structures to complete the installation, without the need to use additional fixing tools or materials, which greatly improves the construction efficiency. Due to the close fit between the protrusions and the depressions, the insulation structure is not prone to loosening or falling off during long-term use, reducing the frequency of maintenance and replacement, thereby reducing maintenance costs. The design of the protrusions and depressions can effectively prevent impurities such as moisture and dust from entering the insulation layer 2, reducing the risk of erosion and damage to the insulation material, thereby extending the service life of the insulation system.

[0038] It is further configured as follows: the insulation body includes an outer protective plate 1, an insulation layer 2 and an aluminum foil heat reflection layer 3, the outer protective plate 1 is the outermost layer of the insulation body, the aluminum foil heat reflection layer 3 is the innermost layer of the insulation body, and the insulation layer 2 is between the outer protective plate 1 and the aluminum foil heat reflection layer 3.

[0039] Specifically, the outer protective plate 1 is made of galvanized steel plate to form a semi-cylindrical shape, which is convenient for installing the insulation body after the pipeline 5 is installed. An aluminum foil heat reflective layer 3 is added between the pipeline 5 and the insulation layer 2. The aluminum foil heat reflective layer 3 can effectively reflect the heat emitted by the working steel pipe, reduce heat transfer, and thus enhance the insulation effect. The aluminum foil heat reflective layer 3 has a moisture-proof effect, which can prevent the insulation layer from being damaged due to moisture and increase the life of the insulation cotton. Aluminum foil is corrosion-resistant and can effectively protect the working steel pipe from corrosion. The insulation layer 2 is made of centrifugal glass wool, silicate and other materials. The insulation cotton is layered and staggered to reduce heat loss. When the insulation structure is connected front and back, the end to end connection is connected by setting a connecting protrusion 9 and a connecting groove 10 at both ends. When the insulation structure is connected up and down, a seal is formed by the longitudinal concave-convex structure to form the overall insulation structure of the pipeline 5.

[0040] Further, a connection plate 6 is provided on the outer side of the outer protection plate 1, wherein when the two insulation structures are buckled, the connection plates 6 of the two outer protection plates 1 are in contact with each other. Through holes are provided on the connection plate 6, and the connection bolts 11 and the connection nuts 12 are used to fix the two connection plates 6 together through the two through holes.

[0041] Specifically, a connecting plate 6 and a bolt hole are provided at the end of the outer protective plate 1. The two sets of insulation structures can be fixed on the insulation pipe through bolt connection. At the same time, the four insulation structures up and down, front and back are fixed to form an insulation whole, so as to realize rapid installation on site. The installation operation does not require fire and does not use large machinery.

[0042] It is further configured that: a rubber gasket 13 is also provided at the joint of the two connecting plates 6. A strip rubber gasket 13 is provided between the connecting surfaces of the outer guard plates, and when the two sets of thermal insulation structures are butted against each other, a good seal is formed to increase the thermal insulation effect. The rubber gasket 13 is configured as an H-shaped structure, which can form a vacuum cavity when squeezed. When the squeezing force of this structure is reduced, the vacuum cavity can play a negative pressure adsorption role, forming a better sealing effect.

[0043] Specifically, when the two sets of thermal insulation structures are butt-jointed, the rubber gasket 13 can fill the tiny gap between the connecting plates 6 to form a tight seal. This effectively prevents heat from leaking from the connection and significantly improves the thermal insulation effect. When the H-shaped rubber gasket 13 is squeezed, its internal space will be compressed to form a vacuum cavity. This vacuum cavity not only provides additional thermal insulation effect, but also can further enhance the sealing of the connection through negative pressure adsorption when the extrusion force is reduced. The negative pressure adsorption effect of the rubber gasket 13 makes the two sets of thermal insulation structures tighter at the connection, and is not easily loosened or deformed due to external factors. This improves the overall stability and reliability of the thermal insulation system.

[0044] Further, a clamping ring 14 is provided on the inner side of the outer protection plate 1, and fixing buckles 15 are provided at both ends of the inner fixing ring 4, and the fixing buckles 15 are clamped into the clamping ring 14. The clamping ring 14 is fixedly connected to the inner side of the outer protection plate 1, and the clamping ring 14 is parallel to the inner fixing ring 4.

[0045] Specifically, the inner fixing ring 4 fixes the aluminum foil heat reflective layer 3 and the thermal insulation cotton on the outer protective plate to form a whole with the outer protective plate. The fixing clips arranged at both ends of the inner fixing ring 4 are connected to the clamping ring 14 arranged on the outer protective plate, and the fixing method of the inner fixing ring 4 being clamped by the rebound force after deformation is utilized to facilitate installation and disassembly. The inner fixing ring 4 is arranged in parallel with the outer protective plate 1, and a concave-convex structure is arranged at the interface of the thermal insulation structure to ensure that the thermal insulation cotton is not squeezed by external force, to avoid the increase of the density of the thermal insulation cotton, to maintain the content of the air layer in the material, and to effectively maintain the thermal insulation effect of the thermal insulation cotton. The outer layer of the inner fixing ring 4 is in contact with the insulated pipe, and a ceramic coating is sprayed on it for thermal insulation treatment to block the heat transfer of the insulated pipe and avoid the generation of thermal bridges or cold bridges that lead to reduced thermal insulation effect.

[0046] It is further configured as follows: a docking protrusion 7 is provided at one end of the inner fixing ring 4, and a docking hole 8 is provided at the other end, wherein when the two heat-insulating structures are buckled, the docking protrusion 7 of one inner fixing ring 4 is inserted into the docking hole 8 of the other inner fixing ring 4.

[0047] Specifically, a butt joint convex rod 7 is provided on the convex structure of the inner fixed ring 4, and a butt joint hole 8 is provided on the groove of the inner fixed ring 4, which can increase the precision of the butt joint installation and facilitate installation. Through the cooperation of the butt joint convex rod 7 and the butt joint hole 8, it can be ensured that the two thermal insulation structures achieve a higher alignment accuracy when buckled. This design reduces the human error in the installation process and makes the connection between the thermal insulation structures more compact and accurate. With the guidance of the butt joint convex rod 7 and the butt joint hole 8, the installer can more easily align and buckle the two thermal insulation structures together. This not only reduces the difficulty of installation, but also improves the installation efficiency. When the butt joint convex rod 7 is fully inserted into the butt joint hole 8, the connection between the two thermal insulation structures will be more stable. This mechanical connection method can effectively prevent the thermal insulation structure from loosening or displacement during use. Due to the close cooperation of the butt joint convex rod 7 and the butt joint hole 8, it can be ensured that the connection between the thermal insulation structures has good sealing. This helps to prevent heat from leaking from the connection and improve the thermal insulation effect.

[0048] It is further configured as follows: a connection protrusion 9 is provided at the head end of the insulation structure, and a connection groove 10 is provided at the tail end, wherein when the two insulation structures are connected head to tail, the connection protrusion 9 is engaged with the connection groove 10. When the insulation structures are connected front to back, the end to end connection is made by the connection protrusions 9 and the connection grooves 10 provided at both ends. When the insulation structures are connected up and down, a seal is formed by the longitudinal concave-convex structure to form an overall insulation structure of the pipeline 5.

[0049] The working principle and beneficial effects of the utility model are:

[0050] The utility model is applied to engineering practice, and the integrated thermal insulation structure fits tightly to the surface of the pipe 5, reducing the path of heat loss, thereby improving the thermal insulation effect, reducing energy consumption, and improving energy efficiency. The pre-installed design allows the pipe 5 system to be quickly assembled at the construction site, without the need for cumbersome thermal insulation material pasting and other processes, which not only shortens the construction period, but also reduces construction costs. The integrated thermal insulation structure is tightly combined with the pipe 5, enhancing the overall stability of the pipe 5 and improving its earthquake resistance, wind resistance and other capabilities.
