Description

Technical Field

[0001] The utility model relates to the technical field of single-cable net curtain wall, in particular to a single-cable net curtain wall damping device. Background Art

[0002] Single cable net curtain wall is a special building curtain wall structure, which belongs to the cable structure point-supported glass curtain wall. It abandons the traditional rigid frame, and the supporting load-bearing structure is composed of high-strength steel cables in horizontal or vertical directions. The steel cables form a stable and elastic network through pre-tensioning force to support glass curtain wall panels or other light-transmitting material curtain wall panels.

[0003] In order to alleviate the vibration problem caused by external dynamic loads such as wind loads and earthquakes, it is necessary to install damping devices at each support point of the single-cable net curtain wall to absorb and consume the energy generated by external dynamic loads, reduce the vibration amplitude of the curtain wall panels, and reduce the damage to the single-cable net curtain wall system caused by vibration and impact. The viscous damper currently used in curtain wall structures is installed at key nodes or connection points. It consumes energy through the resistance generated by the viscous medium when passing through the damping hole, thereby reducing structural vibration and controlling the vibration of the cable net under wind loads, earthquakes or other external forces. However, it was found that the glass of the single-cable net curtain wall concentratedly reflects sunlight in the damper installation area to form hot spots, especially in the summer when the high temperature and direct sunlight aggravate the local temperature rise, causing the internal seals or structural parts of the damper to deform, resulting in leakage of the viscous medium or a decrease in viscosity, reducing the damping effect and affecting the vibration resistance of the single-cable net curtain wall structure. Utility Model Content

[0004] In order to solve the problems in the above-mentioned background technology, the utility model provides a single cable net curtain wall damping device.

[0005] The utility model solves the technical problem by adopting the following scheme: a single cable net curtain wall damping device comprises a damping body, a first mounting seat arranged at one end of the damping body for fixing with the cable net, and a second mounting seat arranged at the other end of the damping body for fixing with the building wall. The damping body comprises a cylinder, a damping chamber arranged in the cylinder, a piston member arranged in the damping chamber, and a guide column with one end inserted into the cylinder and fixedly connected with the piston member. A damping medium is arranged in the damping chamber. The other end of the guide column is fixedly connected with the first mounting seat. A fixing hole is arranged on the first mounting seat for fixing with the cable net. A heat dissipation component is also arranged outside the damping body.

[0006] By adopting the above technical solution, the piston slides freely in the damping cavity, moves with the vibration of the cable net, generates damping force through the flow of the damping medium, and effectively consumes the vibration energy. In addition, a heat dissipation component is added to the outside of the damping body to effectively control the working temperature of the damping device and prevent the internal components of the damping device and the damping medium from being affected by the high temperature outdoors.

[0007] Furthermore, the heat dissipation assembly includes a heat-conducting shell sleeved on the outer wall of the cylinder and a plurality of heat-dissipating fins arranged on the outer surface of the heat-conducting shell, and the heat-dissipating fins and the heat-conducting shell are an integrated structure.

[0008] By adopting the above technical solution, the heat-conducting shell can conduct the heat of the damping device, and the heat sink promotes natural convection to accelerate the transfer of heat from the heat sink surface to the surrounding environment, which can significantly improve the heat dissipation efficiency to control the operating temperature of the damping device to prevent overheating damage.

[0009] Furthermore, a plurality of heat dissipation fins are densely arranged on both sides of the heat sink.

[0010] By adopting the above technical solution, the heat exchange efficiency can be further enhanced.

[0011] Furthermore, the heat-conducting shell includes a first shell and a second shell, and the first shell and the second shell are provided with extended connecting edges on both sides, and the two corresponding extended connecting edges are fixedly connected by bolts.

[0012] By adopting the above technical solution, the heat-conducting shell composed of the first shell and the second shell is fixed by setting bolts, so that the heat dissipation component can be conveniently installed on the outside of the damping device, and can be disassembled by unscrewing the bolts, which is convenient for cleaning and maintenance.

[0013] Furthermore, a layer of graphene coating is sprayed on the heat sink and the heat sink fins.

[0014] By adopting the above technical solution, the graphene coating forms a heat conduction surface, which promotes the rapid transfer of heat to the surrounding air and further optimizes the heat dissipation efficiency.

[0015] Furthermore, the heat-conducting shell, heat sink and heat sink fins are all made of aluminum alloy.

[0016] By adopting the above technical solution, the aluminum alloy has a higher thermal conductivity and can quickly transfer the heat from the internal heat source to the surface for heat dissipation.

[0017] In summary, the beneficial effects of the utility model are as follows: the first mounting seat can be firmly connected to the cable net through the fixing hole in the first mounting seat, and the second mounting seat is fixed to the wall to ensure the stability of the damping device installation, and when the cable net is vibrated by external strong winds, the piston slides in the damping cavity and is damped by the flow of the damping medium to generate a damping force, effectively consuming vibration energy. The heat dissipation component includes a heat-conducting shell, a heat sink and heat-dissipating fins, all of which are heat-conducting materials, which can increase the contact area with the air, accelerate the heat exchange process, effectively control the working temperature of the damping device, and ensure its long-term stable operation.

For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.

[0026] like Figures 1 to 3As shown, a single cable net curtain wall damping device, wherein this embodiment includes a damping body 1, a first mounting seat 2 provided at one end of the damping body 1 for fixing to the cable net, and a second mounting seat 3 provided at the other end of the damping body 1 for fixing to the building wall. The damping body 1 includes a cylinder 11, a damping chamber 12 provided in the cylinder 11, a piston member 13 provided in the damping chamber 12, a guide column 14 with one end inserted into the cylinder 11 and fixedly connected to the piston member 13, and a damping medium 15 is provided in the damping chamber 12, and the other end of the guide column 14 is fixedly connected to the first mounting seat 2, and a fixing hole 21 fixed to the cable net is provided on the first mounting seat 2, and a heat dissipation component 4 is also provided outside the damping body 1.

[0027] This embodiment forms a closed hydraulic system through components such as a cylinder 11, a damping chamber 12, a piston 13 and a guide column 14. The damping chamber 12 provided inside the cylinder 11 is filled with a special damping medium 15, such as a high-performance oil. The viscosity and thermal stability of the medium are strictly screened to ensure that a constant damping effect can be provided under various working conditions. The piston 13 slides freely in the damping chamber 12, moves with the vibration of the cable net, and generates a damping force through the flow of the damping medium 15, effectively consuming vibration energy. One end of the guide column 14 is fixedly connected to the piston 13, extends through the cylinder 11 to the outside, and is connected to the first mounting seat 2 to form a solid force transmission channel. The first mounting seat 2 is designed with a fixing hole 21 that is directly fixed to the cable net, which ensures the stable connection between the damping device and the cable net structure, so that the vibration can be effectively transmitted to the damping body 1 through the guide column 14. The other end of the damping body 1 is provided with a second mounting seat 3, which is specially designed to be firmly fixed to the building wall to ensure that the entire damping device remains stable when subjected to huge vibration energy. Considering the possible accumulation of heat energy during the damping process and its impact on internal components and damping medium 15, a heat dissipation component 4 is added to the outside of the damping body 1 to effectively control the working temperature of the damping device and ensure its long-term stable operation.

[0028] like Figure 2 As shown, the heat dissipation assembly 4 of this embodiment includes a heat-conducting shell 41 mounted on the outer wall of the cylinder 11 and a plurality of heat sinks 42 arranged on the outer surface of the heat-conducting shell 41, and the heat sink 42 and the heat-conducting shell 41 are an integral structure. The heat-conducting shell 41, which is closely attached to the outer wall of the cylinder 11, is made of a metal with excellent thermal conductivity to ensure that the heat transferred from the inside of the damping cavity 12 can be quickly and evenly distributed to the surface of the heat-conducting shell 41. The size and shape of the heat-conducting shell 41 precisely match the cylinder 11, and the heat sink 42 and the heat-conducting shell 41 are an integral structure. The heat sink 42 extends directly from the outer surface of the heat-conducting shell 41 to form a continuous and regular fin shape. It is intended to maximize the contact area between the air and the heat sink 42, promote natural convection, and accelerate the transfer of heat from the surface of the heat sink 42 to the surrounding environment, which can significantly improve the heat dissipation efficiency to control the working temperature of the damping device to prevent overheating damage.

[0029] like Figure 2 As shown, a plurality of heat dissipation fins 43 are densely arranged on both sides of the heat sink 42 of this embodiment. A large number of small heat dissipation fins 43 are arranged on both sides of each heat sink 42, and the fins are closely arranged like fish scales, which greatly increases the surface area in contact with the air, ensuring that the heat dissipation efficiency can be significantly improved even under low wind speed or limited ventilation conditions.

[0030] like Figure 2 As shown, the heat-conducting shell 41 of this embodiment includes a first shell 411 and a second shell 412. Extended connecting edges 413 are provided on both sides of the first shell 411 and the second shell 412, and the two corresponding extended connecting edges are fixedly connected by bolts 5. The heat-conducting shell 41 is composed of the first shell 411 and the second shell 412, and is fixed by bolts 5 provided on the edge extended edges. The heat dissipation assembly 4 can be conveniently installed on the outside of the damping device, and can be disassembled by unscrewing the bolts 5, which is convenient for cleaning and maintenance.

[0031] Specifically, a layer of graphene coating is sprayed on the heat sink 42 and the heat sink fins 43 of the above structure. The heat-conducting shell, the heat sink 42 and the heat sink fins 43 are all made of aluminum alloy. Aluminum alloy has a high thermal conductivity and can quickly transfer the heat from the internal heat source to the surface; and because of its relatively low density, the weight of the overall structure can be reduced. Graphene, as a two-dimensional carbon nanomaterial, has extremely high thermal conductivity and excellent thermal radiation performance. Spraying it on the surface of the heat sink 42 and the heat sink fins 43 can construct an ultra-thin and efficient heat conduction layer, which can significantly increase the speed of heat transfer from the aluminum alloy matrix to the air and enhance the heat dissipation effect.

[0032] In summary, the beneficial effects of this embodiment are as follows: this embodiment can be stably connected to the cable net through the fixing hole 21 in the first mounting seat 2, and the second mounting seat 3 is fixed to the wall, ensuring the installation stability of the damping device. The damping device is formed by the cylinder 11, the damping chamber 12, the piston 13 and the guide column 14. The guide column 14 and the first mounting seat 2 transmit the vibration of the curtain wall panel to the piston 13, and the piston 13 slides freely in the damping chamber 12, moves with the vibration of the cable net, and generates damping force through the flow of the damping medium 15 in the damping chamber 12, effectively consuming vibration energy. The heat-conducting shell 41 mounted on the outer wall of the cylinder 11, the multiple heat sinks 42 arranged on the outer surface of the heat-conducting shell 41, and the heat sink fins 43 around the heat sink 42 are all made of high thermal conductivity aluminum alloy and coated with graphene on the outside, which can significantly enhance the speed of heat transfer from the aluminum alloy matrix to the air, and can quickly and evenly distribute the heat transferred from the damping cavity 12 to the surface of the heat-conducting shell 41 and diffuse it into the air to achieve heat dissipation.

[0033] The embodiments described above are only preferred implementation modes of the present utility model and cannot be used to limit the protection scope of the present utility model. Any non-substantial changes and modifications made by technicians in this field on the basis of the utility model shall fall within the protection scope of the present utility model.
