Description

Technical Field

[0001] This utility model relates to the field of building equipment engineering technology, and in particular to a ventilation system duct installation structure. Background Technology

[0002] Ventilation system duct installation structure, through the scientific and reasonable combination of pipes, connectors, supports, adjustment components, and purification devices, introduces fresh air into the room and exhausts polluted air, moisture, odors, and harmful pollutants from industrial production. It not only effectively ensures indoor air quality and creates a comfortable and healthy living and working environment for people, but also assists in building fire safety by promptly removing smoke in the event of a fire. At the same time, it optimizes the industrial production environment, prevents pollutants from damaging equipment, and ensures smooth production. It is an indispensable and important component for maintaining a good indoor and outdoor environment.

[0003] The ventilation system duct installation structure is centered on the power provided by the fan. The air pressure generated by the fan operation drives the air to flow within the system composed of ducts of different materials and shapes. After entering through the air inlet, the air first passes through the purification treatment mechanism such as the filter to improve its quality. Then, according to the control of the regulating mechanism such as the air valve, it is precisely delivered into or out of the room through the air outlet according to a specific path and flow rate. At the same time, the stability of the duct is ensured by the support and fixing structure such as the bracket and hanger. Under the action of aerodynamics and fluid mechanics, it realizes functions such as efficient ventilation, environmental regulation and fire safety assistance.

[0004] However, in existing technologies, some ventilation system duct installation structures lack vibration damping at the connection between the support frame and the roof, resulting in a general lack of vibration damping at this connection point. During ventilation system operation, the mechanical vibration generated by the fan and the vibration caused by airflow within the duct are transmitted to the support frame. Many existing methods of connecting the support frame to the roof use rigid connections, such as directly fixing the support frame to the roof structure with expansion bolts. This connection method lacks necessary elastic buffer components and cannot effectively absorb and attenuate vibration energy. Over time, continuous vibration not only causes the bolts at the connection between the support frame and the roof to loosen and damage the wall structure, but also generates significant noise pollution, affecting the comfort and safety of the surrounding environment. Furthermore, it negatively impacts the service life of the ventilation ducts and related equipment, reducing the stability and reliability of the entire ventilation system. Therefore, this paper proposes a ventilation system duct installation structure to address these problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a ventilation system duct installation structure, which aims to improve the problem that the existing ventilation system duct installation structure has no vibration reduction effect at the connection between the support frame and the roof.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a ventilation system duct installation structure, comprising a fixing plate, a connecting plate one fixedly connected to the bottom end of the fixing plate, two damping columns fixedly connected to both sides of the bottom end of the connecting plate one, a support plate fixedly connected to the adjacent side of the two damping columns, a moving ring fixedly connected to the adjacent side of the two support plates, a vibration damping pad fixedly connected to the top end of the moving ring, a fixing plate fixedly connected to the top end of the vibration damping pad, a connecting column fixedly connected to the bottom end of the fixing plate, a vibration damping ring fixedly connected to the top end of the fixing plate, a bracket fixedly connected to the bottom end of the connecting column, and a connecting plate two fixedly connected to the bottom end of the two brackets.

[0008] As a further description of the above technical solution: the outer side of the functional plate is provided with multiple sliding grooves, and the outer side of the multiple sealing strips is slidably connected to the outer side of the functional plate.

[0011] As a further description of the above technical solution: the external threads of the two nuts are connected to the inner wall of the bottom end of the fixed plate, and the top ends of the two damping rings are connected to the inner wall of the connecting plate.

The multiple sealing structures cooperate and squeeze each other to achieve a high-efficiency sealing effect at the air duct connection and prevent air leakage. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1 to 3 This utility model provides an embodiment of a ventilation system duct installation structure, including a fixing plate 1. A connecting plate 2 is fixedly connected to the bottom end of the fixing plate 1. The connecting plate 2 serves as the foundation fixing component of the entire structure, providing a stable installation base for subsequent components. Two damping columns 3 are fixedly connected to both sides of the bottom end of the connecting plate 2. When the upper structure is subjected to external impact or vibration, the damping columns 3 convert kinetic energy into heat energy through the damping effect of their internal medium, effectively slowing down the transmission speed of the impact force, thereby protecting the entire structure from severe vibration.

[0026] Support plates 4 are fixedly connected to adjacent sides of the two damping columns 3. The function of the support plates 4 is to bear the force transmitted by the damping columns 3 and distribute it evenly to the moving ring 5, while providing a stable support plane for the moving ring 5 to ensure that the moving ring 5 will not tilt or shift when subjected to force. The moving ring 5 is fixedly connected to adjacent sides of the two support plates 4. When the entire structure is subjected to external force, the moving ring 5 can slide slightly along the connecting column 8 under the support of the support plates 4, further playing a buffering role, and at the same time providing an installation base for the vibration damping pad 6. The top of the moving ring 5 is fixedly connected to the vibration damping pad 6. When the fixed plate 7 is subjected to vibration or impact, the vibration damping pad 6 can absorb and dissipate energy through its own elastic deformation, effectively reducing the intensity of vibration transmitted to the upper structure, while reducing hard collisions between the fixed plate 7 and the moving ring 5.

[0027] A fixed plate 7 is fixedly connected to the top of the vibration damping pad 6. The surface of the fixed plate 7 is flat, providing a stable mounting plane for the connecting column 8 and the vibration damping ring 9. Through the buffering effect of the vibration damping pad 6, the impact of force on the structure below is reduced. A connecting column 8 is fixedly connected to the bottom of the fixed plate 7. The main function of the connecting column 8 is to transfer the force of the fixed plate 7 to the support 10 below, and at the same time provide guidance for the moving ring 5, ensuring that the moving ring 5 does not shift during sliding. A vibration damping ring 9 is fixedly connected to the top of the fixed plate 7. When the structure above vibrates, the vibration damping ring 9 absorbs and buffers the vibration energy from all directions through its own elastic deformation, further reducing the impact of vibration on the entire structure.

[0028] A bracket 10 is fixedly connected to the bottom end of the connecting column 8. The bracket 10 provides stable support for the entire structure, enhances its anti-overturning ability, and ensures that the entire structure will not tilt or collapse under external forces. A connecting plate 12 is fixedly connected to the bottom end of both brackets 10. The surface of the connecting plate 12 is flat, providing a stable installation foundation for the duct 13 and enhancing the stability and load-bearing capacity of the entire structure. Nuts 11 are threaded onto the front and rear sides of the connecting plate 12. The duct 13 is fixedly connected to the top end of the connecting plate 12. The duct 13 is mainly used for ventilation or gas transportation. In practical applications, it can be connected to a ventilation system or other gas transportation equipment. A sealing assembly for sealing is fixedly connected to the left inner wall of the duct 13.

[0029] Reference Figures 3 to 5 The sealing assembly includes a functional plate 14, which serves as the core load-bearing structure. Its shape is adapted to the connection point of the duct 13, ensuring a stable installation. The functional plate 14 is externally fixedly connected to the left side of the duct 13. This connection directly seals and protects the interface of the duct 13, ensuring the sealing assembly and duct 13 work together to effectively prevent gas leakage from the connection point. Multiple rotating shafts 15 are externally fixedly connected to the functional plate 14. The axis of each rotating shaft 15 is perpendicular to the rotation direction of the sealing strip 17, providing a stable fulcrum for the sealing strip 17.

[0030] Multiple rotating shafts 15 are rotatably connected to sealing strips 17 on their opposite sides. When sealing is required, the sealing strips 17 can rotate to fit the interface of the air duct 13, using their own elastic deformation to fill the gaps and prevent gas leakage. Multiple rotating shafts 16 are fixedly connected to the inner wall of the functional plate 14. The rotating shafts 16 provide rotational support for the sealing strips 18. The way they are fixed to the functional plate 14 ensures installation accuracy and ensures the stability and accuracy of the sealing strips 18 during rotation, enabling the sealing strips 18 to work together with the sealing strips 17 to complete the sealing work.

[0031] Multiple rotating shafts 16 are rotatably connected to adjacent sides of sealing strips 18. When sealing strip 17 fits against external gaps, sealing strip 18 can rotate to fit against the internal interface of duct 13, forming a three-dimensional sealing structure, effectively improving the sealing effect and preventing gas leakage from different directions. Multiple shrinkage columns 20 are fixedly connected to adjacent sides of the sealing strips 17. When sealing strip 17 rotates to its sealing position, shrinkage columns 20 can extend, pushing sealing strip 17 to fit more tightly against the interface surface of duct 13, enhancing sealing pressure.

[0032] Multiple sealing strips 18 are fixedly connected to adjacent sides of multiple contraction columns 19. When the sealing strips 18 rotate to the internal interface of the duct 13, the contraction columns 19 extend, causing the sealing strips 18 to fit tightly against the inner wall of the interface, working in conjunction with the contraction columns 20. Multiple contraction columns 22 are fixedly connected to the right inner wall of the duct 13. Their function is to provide support and adjustment for the sealing ring 21. Through telescopic movement, they control the position and pressure of the sealing ring 21, ensuring that the sealing ring 21 can flexibly adjust the sealing force according to the gas pressure inside the duct 13 and the interface conditions. The sealing ring 21 is fixedly connected to the right side of the multiple contraction columns 22. When there is gas flowing in the duct 13, the contraction columns 22 push the sealing ring 21 to fit tightly against the inner wall of the duct 13, forming a sealing surface and preventing gas leakage.

[0033] Reference Figures 1 to 3 The external surface of the functional plate 14 has multiple grooves, which guide and limit the sliding of the sealing strip 17, ensuring its stability during movement and preventing displacement or jamming. The adjacent sides of the multiple sealing strips 17 are slidably connected to the external surface of the functional plate 14. When sealing is required, the sealing strip 17 can slide along the grooves to the designated position and fit against the interface of the duct 13. The distant sides of the multiple sealing strips 18 are slidably connected to the internal wall of the functional plate 14. By sliding along the internal wall of the functional plate 14, the sealing strips 18 can be flexibly adjusted in position to accurately fit against the internal interface of the duct 13.

[0034] The sliding connection ensures that the sealing strip 18 maintains a precise trajectory during movement, cooperating with the sealing strip 17 to achieve a comprehensive seal on the duct 13 interface from both the inside and outside. The adjacent sides of multiple contraction columns 20 are fixedly connected to the inner wall of the functional plate 14. When enhanced sealing is required, the contraction columns 20 extend to push the sealing strip 17. The distal sides of multiple contraction columns 19 are fixedly connected to the inner wall of the functional plate 14. Similar to contraction columns 20, the distal sides of contraction columns 19 are fixed to the inner wall of the functional plate 14, providing extension and retraction power support for the sealing strip 18. The outer side of the sealing ring 21 is slidably connected to the right side of the duct 13. The inner wall of the duct 13 is designed with an annular groove or guide rail, and the external protrusion or slider structure of the sealing ring 21 cooperates with it to form a sliding connection.

[0035] Driven by the contraction column 22, the sealing ring 21 can slide within the groove on the inner wall of the duct 13, achieving contact or separation with the inner wall of the duct 13. Multiple sealing strips 17 are externally slidably connected to the inner wall of the duct 13. During the sealing process, the sealing strips 17 slide from the outside of the functional plate 14 to the inner wall of the duct 13, tightly adhering to the interface surface. Together with the sealing ring 21 and sealing strips 18, they form a multi-layer sealing structure, effectively preventing gas leakage and improving the reliability and stability of the seal. Multiple sealing strips 18 are externally slidably connected to the inner wall of the duct 13. When the sealing strips 18 slide into position, they cooperate with the sealing strips 17 and the sealing ring 21 to further enhance the sealing effect from inside the duct 13, effectively preventing gas leakage from all directions of the duct 13 interface.

[0036] The external threads of the two nuts 11 are connected to the inner wall of the bottom end of the fixed plate 1, ensuring the accuracy and stability of the installation of the connecting plate 2. Simultaneously, the threaded connection facilitates disassembly and maintenance; when maintenance is required on the connecting plate 2 or components below it, the nuts 11 can be easily unscrewed to remove the connecting plate 2. The tops of the two damping rings 9 are connected to the inner wall of the connecting plate 2. When the connecting plate 2 is subjected to vibration or impact, the damping rings 9 can absorb and dissipate energy through their elastic deformation, protecting the components connected to the connecting plate 2 from vibration and improving the stability and reliability of the entire device.

[0037] A groove is formed on the inner wall of the bottom end of the connecting plate 2. The groove provides guidance and limitation for the sliding of the support plate 4, ensuring that the support plate 4 remains stable during movement and does not tilt or deviate. Multiple support plates 4 are externally slidably connected to the inner wall of the connecting plate 2. When the entire device is subjected to external force, the support plates 4 can slide within the groove, consuming some energy through sliding friction. At the same time, in conjunction with components such as the damping column 3, they further play a role in buffering and vibration reduction, ensuring that the device remains stable during operation.

[0038] The two connecting columns 8 are externally slidably connected to the inner wall of the moving ring 5, consuming energy through sliding friction. Simultaneously, in conjunction with components such as the vibration damping pad 6, they further buffer and absorb vibrations, reducing the impact of vibrations on the upper structure and improving the stability and reliability of the device. The two connecting columns 8 are also externally slidably connected to the inner wall of the vibration damping pad 6. The inner wall of the vibration damping pad 6 is also provided with sliding grooves adapted to the exterior of the connecting columns 8. When the connecting columns 8 slide on the inner wall of the vibration damping pad 6, the vibration damping pad 6 can absorb and buffer the vibrations and impacts transmitted by the connecting columns 8 through its own elastic deformation.

[0039] Working Principle: When the duct 13 vibrates due to fan operation or airflow impact, the duct 13 drives the connecting plate 12 to move, which in turn causes the fixed plate 7 to shift through the bracket 10 and connecting column 8. The fixed plate 7 compresses the damping ring 9 and pushes the damping pad 6 and moving ring 5 downward. The moving ring 5 drives the support plate 4 to slide within the groove of the connecting plate 2, while simultaneously compressing the damping column 3. During this process, the damping ring 9 and damping pad 6 absorb vibration energy through flexible deformation, the damping column 3 reduces the vibration amplitude through elastic buffering, and the sliding of the moving ring 5 adjusts the buffer space. Conversely, it prevents building vibration from affecting the device, thereby achieving all-round vibration damping protection for the duct 13, reducing problems such as pipe loosening and component wear caused by vibration, and improving the operational stability and service life of the ventilation system.

[0040] When the two ducts 13 are connected, the right duct 13 pushes the sealing ring 21 to squeeze the shrink column 22. The sealing ring 21 slides along the inner wall of the duct 13 and fits tightly against the inner wall of the duct 13. At the same time, the functional plate 14 drives the rotating shaft 15 and rotating shaft 26 to rotate, causing the sealing strip 17 and sealing strip 28 to flip outward and inward respectively around their respective rotating shafts 15 and 26. The sealing strip 17 slides along the outer groove of the functional plate 14 through the elastic support of the shrink column 20 and presses against the inner wall of the duct 13. The sealing strip 28 slides along the inner groove of the functional plate 14 under the action of the shrink column 19 and seals the joint gap, thereby achieving a high-efficiency seal at the connection of the ducts 13, effectively preventing air leakage and dust intrusion, and improving the energy efficiency and cleanliness of the ventilation system.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
