Description

Technical Field

[0001] This application relates to the field of building energy conservation technology, and in particular to an ultra-low energy consumption building through-wall pipe system. Background Technology

[0002] Currently, the main solutions for pipe penetration through external walls are as follows: First, ordinary metal or plastic pipes are used to directly penetrate the external wall, and expanding foam or sealant is filled between the pipe and the wall. This method is simple to construct, but its sealing and insulation properties are poor, making it prone to air infiltration and resulting in poor insulation performance. Second, an insulated sleeve is installed on the outside of the pipe, which can effectively reduce heat loss, but it increases the complexity and cost of construction, limiting the application of this solution. Third, prefabricated wall sleeves are used, and the pipe is fixed inside the sleeve before sealing. This can improve the sealing performance to some extent, but its adaptability to pipe size and wall thickness is poor, limiting its widespread application.

[0003] In summary, existing technologies, while meeting the requirement of pipes passing through external walls, lack a balance between sealing performance, thermal insulation, and ease of construction. Sealing materials between pipes and walls are prone to aging and cracking, leading to air infiltration; inadequate insulation measures result in significant thermal bridging; and prefabricated sleeves have poor applicability to pipe sizes and wall thicknesses, limiting their widespread application in practical engineering projects.

[0004] Therefore, there is an urgent need for a new technical solution that can simplify the construction process, improve project efficiency and expand the application range while ensuring sealing and insulation effects. Utility Model Content

[0005] In order to address the problem that existing ultra-low energy building pipe penetration systems suffer from inherent design characteristics, the inventors have found that existing pipes cannot simultaneously guarantee sealing and insulation effects when passing through external walls, and the construction process is complex, effectively reducing project efficiency. Therefore, this application provides an ultra-low energy building pipe penetration system.

[0006] The ultra-low energy consumption building through-wall pipe system provided in this application adopts the following technical solution: including a wall, an installation hole provided on the wall, a main pipe provided in the installation hole, a locking hole provided perpendicular to the central axis of the installation hole, a fixing hole provided on one side of the installation hole and connected to the locking hole, and a locking element provided in the locking hole for locking the main pipe; The locking element includes a locking unit and an adjustment unit for adjusting the locking unit.

[0007] By adopting the above technical solution, the wall serves as a supporting structure, providing an installation base; mounting holes are used for the installation of the main pipe, ensuring a fixed connection between the main pipe and the wall; locking holes cooperate with fixing holes to install locking components, securely locking the main pipe; fixing holes communicate with locking holes, facilitating the installation and adjustment of the locking components. The locking component consists of two parts: a locking unit and an adjusting unit. The locking unit directly locks the main pipe, while the adjusting unit is used to adjust the position and tightness of the locking unit.

[0008] As a preferred embodiment, the locking unit includes a fixed tube fixedly connected to one end of the locking hole, an adjusting tube disposed at the other end of the locking hole, a first locking groove disposed on the fixed tube, and a second locking groove disposed on the adjusting tube. The first locking groove and the second locking groove are respectively configured as arc-shaped structures, and the first locking groove and the second locking groove are respectively disposed relative to the fixed hole.

[0009] By adopting the above technical solution, the fixed pipe is fixed to one end of the locking hole via a connection, providing a stable foundation support; the adjusting pipe is located at the other end of the locking hole and can be extended or retracted relative to the fixed pipe, thereby adjusting the expansion range of the locking hole. The first locking groove and the second locking groove are fixed to the fixed pipe and the adjusting pipe respectively, and are designed in an arc shape to accommodate main pipes of different outer diameters. The adjusting component can easily adjust the relative distance between the fixed pipe and the adjusting pipe, thereby precisely adjusting the distance between the first locking groove and the second locking groove, achieving effective fixing of main pipes of different outer diameters.

[0010] As a preferred embodiment, a fixing sealing ring is provided at the connection between the fixing pipe and the wall. The fixing sealing ring is connected to the wall by fasteners. An elastic gasket is provided at the connection between the fixing sealing ring and the wall. The elastic gasket is made of EPDM rubber and has a thickness of 2mm to 3mm.

[0011] By adopting the above technical solution, the fixed pipe is connected to the wall through a fixed sealing ring, which effectively prevents water and gas leakage between the pipe and the wall. An elastic gasket, made of EPDM rubber, is located between the fixed sealing ring and the wall, providing not only good cushioning and shock absorption but also further enhancing the sealing performance.

[0012] As a preferred embodiment, the adjustment unit includes an adjustment bolt that passes through the adjustment tube and connects to the fixed tube, a connecting shaft ring disposed at the smooth end of the adjustment bolt, and a limiting groove disposed on the adjustment tube that is adapted to the connecting shaft ring. The limiting groove is disposed circumferentially along the adjustment bolt, and the fixed tube is provided with an adjustment hole that is adapted to the threaded end of the adjustment bolt.

[0013] By adopting the above technical solution, the adjusting bolt is used to fix and adjust the distance between the adjusting tube and the fixed tube; the connecting shaft ring is installed on the smooth end of the adjusting bolt to ensure its fit with the limiting groove, thereby limiting the adjusting bolt from driving the adjusting tube to rotate synchronously; the adjusting hole is set on the fixed tube and fits with the threaded end of the adjusting bolt to ensure that the adjusting bolt can extend into the fixed tube to achieve the fixing and adjustment functions.

[0014] As a preferred embodiment, the system further includes an elastic sealing ring disposed in the inner cavity of the locking hole, a sealing flange disposed at the connection between the regulating pipe and the locking hole, and an insulation layer disposed on the outer periphery of the main pipe. The elastic sealing ring is made of silicone rubber material with a thickness of 8 to 12 mm, preferably 10 mm, and its cross-section is a hollow annular structure.

[0015] By adopting the above technical solution, the elastic sealing ring is made of silicone rubber, which can tightly fit the inner cavity of the locking hole, reducing heat exchange and effectively isolating heat conduction. Secondly, the sealing flange is set at the connection between the regulating pipe and the locking hole, effectively sealing the connection and further isolating heat conduction. Finally, the insulation layer is wrapped around the outer perimeter of the main pipe, enhancing the overall insulation and reducing heat loss.

[0016] As a preferred embodiment, the sealing flange is fixedly connected to the wall and slidably connected to the regulating pipe. The sealing flange is made of aluminum alloy and is connected to the wall by fasteners. The thickness is 4-6mm, preferably 5mm, and the outer diameter of the sealing flange is 20-30mm larger than the inner diameter of the locking hole.

[0017] By adopting the above technical solution, the sealing flange is mainly made of aluminum alloy material, which has good corrosion resistance and lightweight characteristics. The sealing flange is fixedly connected to the wall, which ensures the stability and sealing between the equipment and the wall, and prevents the intrusion of external air or moisture. Its outer diameter is slightly larger than the inner diameter of the locking hole, which provides space for the free sliding of the regulating pipe, avoids additional stress during the adjustment process, and reduces the risk of sealing failure.

[0018] As a preferred embodiment, the insulation layer is made of polyurethane foam material with a thickness of 15-25 mm, preferably 20 mm, and its thermal conductivity is ≤0.025 W / (m·K).

[0019] By adopting the above technical solution, polyurethane foam material can be tightly bonded to the outer surface of the main pipeline to form a high-efficiency heat insulation layer. This material has a low thermal conductivity, which can greatly reduce the heat transfer efficiency during heat conduction. At the same time, polyurethane foam has good moisture resistance and moisture-proof function, preventing water vapor from entering the insulation layer and ensuring the long-term high efficiency of the material. In addition, polyurethane foam also has a certain degree of toughness, which can remain stable when the pipeline is subjected to pressure or other external forces, avoiding the reduction of insulation effect due to deformation or damage.

[0020] In summary, this application includes the following beneficial technical effects: 1. The wall serves as a supporting structure, providing an installation base. Mounting holes are used for installing the main pipe, ensuring a secure connection between the main pipe and the wall. Locking holes work in conjunction with fixing holes to install locking components, firmly locking the main pipe in place. Fixing holes communicate with locking holes, facilitating the installation and adjustment of the locking components. The locking component consists of two parts: a locking unit and an adjusting unit. The locking unit directly locks the main pipe, while the adjusting unit is used to adjust the position and tightness of the locking unit. 2. The elastic sealing ring is made of silicone rubber, which can tightly fit the inner cavity of the locking hole, reducing heat exchange and effectively isolating heat conduction. Secondly, the sealing flange is located at the connection between the regulating pipe and the locking hole, effectively sealing the connection and further isolating heat conduction. Finally, the insulation layer wraps around the outer perimeter of the main pipe, enhancing overall insulation and reducing heat loss. In summary, these design features work together to significantly reduce energy loss caused by thermal bridging by isolating heat conduction paths, thereby improving the system's energy efficiency and thermal insulation performance.

The locking mechanism includes a locking unit and an adjustment unit for adjusting the locking unit. The wall 1 serves as a supporting structure, providing an installation base. The mounting hole 100 is for installing the main pipe 3, ensuring a fixed connection between the main pipe 3 and the wall 1. The locking hole 200 cooperates with the fixing hole 101 to install the locking mechanism and securely lock the main pipe 3. The fixing hole 101 communicates with the locking hole 200, facilitating the installation and adjustment of the locking mechanism. The locking mechanism comprises two parts: a locking unit and an adjustment unit. The locking unit directly locks the main pipe 3, while the adjustment unit adjusts the position and tightness of the locking unit. The working principle is as follows: First, the main pipe 3 is installed in the mounting hole 100. Then, the position of the locking mechanism is adjusted using the adjustment unit to ensure that the locking unit can be correctly inserted into the locking hole 200 and the fixing hole 101, thereby securely locking the main pipe 3 and ensuring the stability and reliability of the device.

Figure 3 , Figure 4 and Figure 5The locking unit includes a fixed tube 41 fixedly connected to one end of the locking hole 200, an adjusting tube 42 disposed at the other end of the locking hole 200, a first locking groove 412 disposed on the fixed tube 41, and a second locking groove 421 disposed on the adjusting tube 42. The first locking groove 412 and the second locking groove 421 are respectively designed with arc-shaped structures, and the first locking groove 412 and the second locking groove 421 are respectively disposed relative to the fixed hole 101. The fixed tube 41 is fixed to one end of the locking hole 200 by a connection, providing a stable foundation support; the adjusting tube 42 is disposed at the other end of the locking hole 200 and can be extended and retracted relative to the fixed tube 41, thereby adjusting the expansion range of the locking hole 200. The first locking groove 412 and the second locking groove 421 are respectively fixed on the fixed tube 41 and the adjusting tube 42, and are designed with arc shapes to accommodate main pipes 3 with different outer diameters. The adjusting component can easily adjust the relative distance between the fixed pipe 41 and the adjusting pipe 42, thereby precisely adjusting the distance between the first locking groove 412 and the second locking groove 421 to effectively fix the main pipes 3 with different outer diameters. The working principle is: by adjusting the relative distance between the fixed pipe 41 and the adjusting pipe 42, the distance between the first locking groove 412 and the second locking groove 421 is changed, thus adapting to main pipes 3 of different diameters and ensuring the stability of the main pipe 3 installation.

The elastic gasket, located between the fixing sealing ring 411 and the wall 1, is made of EPDM rubber and not only provides good cushioning and shock absorption but also further enhances the sealing performance.

The limiting groove 511 is arranged circumferentially along the adjustment bolt 5. The fixed tube 41 is provided with an adjustment hole 413 that is adapted to the threaded end of the adjustment bolt 5. The adjustment bolt 5 is used to fix and adjust the distance between the adjustment tube 42 and the fixed tube 41. The connecting shaft ring 51 is installed on the smooth end of the adjustment bolt 5 to ensure its cooperation with the limiting groove 511, thereby limiting the adjustment bolt 5 from driving the adjustment tube 42 to rotate synchronously. The adjustment hole 413 is located on the fixed tube 41 and cooperates with the threaded end of the adjustment bolt 5 to ensure that the adjustment bolt 5 can extend into the fixed tube 41 to achieve the functions of fixing and adjusting. Working principle: By rotating the adjusting bolt 5, the connecting shaft ring 51 engages with the limiting groove 511 to restrict the rotation of the adjusting tube 42. Meanwhile, the adjusting bolt 5 extends into the fixed tube 41 through the adjusting hole 413, changing its length relative to the fixed tube 41, thereby adjusting the distance between the fixed tube 41 and the adjusting tube 42. During this process, it is ensured that the first locking groove 412 and the second locking groove 421 remain aligned with the main pipe 3, achieving the purpose of fixing the main pipe 3.

The elastic sealing ring 201 is made of silicone rubber with a thickness of 8-12 mm, preferably 10 mm, and has a hollow annular cross-section. The silicone rubber material allows the elastic sealing ring 201 to fit tightly against the inner cavity of the locking hole 200, reducing heat exchange and effectively isolating heat conduction. Secondly, the sealing flange 202, located at the connection between the regulating pipe 42 and the locking hole 200, effectively seals the connection, further isolating heat conduction. Finally, the insulation layer wraps around the outer periphery of the main pipe 3, enhancing overall insulation and reducing heat loss. In summary, these designs work together to significantly reduce energy loss caused by thermal bridging by isolating heat conduction paths, thereby improving the system's energy efficiency and insulation performance.

The outer diameter of the sealing flange 202 is 20-30 mm larger than the inner diameter of the locking hole 200. The sealing flange 202 is mainly made of aluminum alloy, which has good corrosion resistance and lightweight properties. The fixed connection between the sealing flange 202 and the wall 1 ensures the stability and sealing between the equipment and the wall 1, preventing the intrusion of external air or moisture. Its design, with an outer diameter slightly larger than the inner diameter of the locking hole 200, provides space for the free sliding of the regulating pipe 42, avoiding additional stress during the adjustment process and reducing the risk of seal failure.

[0030] Please refer to details. Figure 1 The insulation layer 31 is made of polyurethane foam with a thickness of 15-25 mm, preferably 20 mm, and a thermal conductivity ≤0.025 W / (m·K). The polyurethane foam can be tightly bonded to the outer surface of the main pipe 3, forming a highly efficient insulation layer. This material has a low thermal conductivity, which can greatly reduce heat transfer efficiency during heat conduction. Simultaneously, polyurethane foam has good moisture resistance and moisture-proof properties, preventing water vapor from entering the insulation layer and ensuring the long-term high efficiency of the material. Furthermore, polyurethane foam also possesses a certain degree of toughness, enabling it to remain stable when the pipe is subjected to pressure or other external forces, avoiding a reduction in insulation effect due to deformation or damage.

[0031] The implementation principle of an ultra-low energy consumption building through-wall pipe system according to an embodiment of this application is as follows: First, the insulation layer is wrapped around the outer perimeter of the main pipe 3. Then, the main pipe 3 is installed in the mounting hole 100. By rotating the adjusting bolt 5, the connecting shaft ring 51 cooperates with the limiting groove 511 to restrict the rotation of the adjusting pipe 42. The adjusting bolt 5 extends into the fixed pipe 41 through the adjusting hole 413, changing its length relative to the fixed pipe 41, thereby adjusting the distance between the fixed pipe 41 and the adjusting pipe 42.
