Description

Technical Field

[0001] The present application relates to the technical field of windproof protection, and in particular to a glass windproof device. Background Art

[0002] As a natural disaster, the destructive power of typhoons cannot be underestimated, especially in coastal areas, where the frequent visits of typhoons pose great challenges to the daily lives and property safety of residents. Whenever a typhoon warning is issued, residents will nervously prepare countermeasures to reduce the damage that may be caused by the typhoon. However, due to the unpredictability and suddenness of typhoons, coupled with economic cost considerations, the window design of most civil buildings does not fully consider the ability to withstand typhoons. In this case, residents often take some temporary measures to protect the windows, such as sticking tape on the glass or installing wooden boards on the outside of the windows, in order to reduce the risk of glass breaking when a typhoon comes.

[0003] Although these methods can provide protection to a certain extent, they have many inconveniences and limitations. First, these measures need to be dismantled after the typhoon, which not only increases the labor intensity of residents, but also is a cumbersome process and brings inconvenience to residents. Second, the reliability of these measures is not high. They are more of a psychological comfort than a real safety guarantee. In addition, since these measures need to be prepared temporarily before the typhoon arrives, their utilization rate is not high. Many times, residents are unable to take these measures in time due to time constraints. Summary of the invention

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Application Overview

[0022] From a physics perspective, glass shattering in typhoon weather or severe convective weather is a complex phenomenon involving the combined effects of multiple physical principles:

[0023] 1. Momentum conservation and kinetic energy transfer: In typhoons or severe convective weather, high-speed flying objects (such as flying sand and rocks) carry a lot of kinetic energy. When these objects hit the glass, according to the law of conservation of momentum, their kinetic energy is quickly transferred to the glass, generating a huge impact force. Once the impact force exceeds the strength threshold of the glass, the glass will break.

[0024] 2. Pressure difference effect: In typhoons or severe convective weather, rapid changes in wind speed will lead to an imbalance in indoor and outdoor pressure. The air pressure is lower on the side with faster wind speed, while the interior of the building is relatively closed and maintains a higher pressure. This pressure difference will produce tensile stress on the glass. If the stress exceeds the elastic limit of the glass, the glass may break because it cannot withstand it.

[0025] 3. Resonance phenomenon: Under strong winds, the glass may vibrate due to the periodic changes in wind pressure. When the vibration frequency is close to the natural frequency of the glass, resonance may occur, and the vibration amplitude of the glass will increase significantly, increasing the possibility of glass damage.

[0026] 4. Fatigue damage: Long-term strong winds may cause fatigue damage to the glass even if the wind speed is not high enough to directly cause the glass to break. This damage is a cumulative effect, especially when there are already tiny cracks in the glass. These cracks will gradually expand under the repeated action of wind pressure, eventually leading to the breakage of the glass.

[0027] In order to solve the above problems, in the embodiment of the present application, a container containing liquid is hung on the glass, which effectively reduces the risk of glass breakage in strong wind weather from four aspects: momentum conservation and kinetic energy transfer, pressure difference effect, resonance phenomenon, and fatigue damage. At the same time, it reduces the fatigue damage of the glass and its fixed edges, thereby extending the service life of the glass.

[0028] After introducing the basic principles of the present application, various non-limiting embodiments of the present application will be described in detail with reference to the accompanying drawings.

[0029] Exemplary Devices

[0030] Figure 1 and Figure 2 The following are schematic diagrams of the structure of a glass windproof device provided in the embodiments of the present application. Figure 1 and Figure 2 As shown, it includes a first connecting structure 2 connected to the glass 1, and a container 3 suspended below the first connecting structure 2; wherein the container 3 is provided with a receiving space 301 for containing liquid; and the volume of the liquid is smaller than the volume of the receiving space 301.

[0031] In the embodiment of the present application, the first connecting structure 2 is used to connect the glass windshield device and the glass 1. The first connecting structure 2 can be detachably connected to the glass 1. Further, the first connecting structure 2 can be detachably connected to the central area of ​​the glass 1.

[0032] In the embodiment of the present application, the container 3 is suspended below the first connection structure 2 and can be used to hold liquid. In actual use, the volume of the liquid needs to be smaller than the volume of the containing space 301 so that the liquid fluctuates when the glass 1 vibrates.

[0033] In the embodiment of the present application, the receiving space 301 for holding liquid on the container 3 may be an open space or a cavity arranged inside the container 3. The number of the receiving spaces 301 may be set as required.

[0034] In the embodiment of the present application, a cavity for holding liquid may be provided inside the container 3, the number of cavities may be set as needed, the positions of the cavities may be arranged vertically, horizontally, or randomly, and there is no limit on the volume size between the cavities.

[0035] In the embodiment of the present application, the container 3 can be made of a material that is tough, impact-resistant, chemically resistant, and non-toxic, such as plastic (PVC, PP, nylon, Teflon, etc.) resin, etc.

[0036] A glass windproof device provided in the embodiment of the present application can achieve the following effects:

[0037] 1. Regarding the pressure difference effect: The glass windshield provided in the embodiment of the present application can apply an inward pulling force and a downward pressure at the inner center of the glass 1 to offset the outward pulling force formed by the external low pressure. The two external forces come from the gravity of the glass windshield itself, which reduces the risk of glass 1 breaking due to imbalance of internal and external pressures.

[0038] 2. Regarding the resonance phenomenon:

[0039] 1) Vibration caused by strong wind: The glass windproof device provided in the embodiment of the present application can apply an inward pulling force and a downward pressure at the inner center of the glass 1. The external forces in two directions change the mass distribution of the glass 1 itself. When the mass of a vibration system increases, it will affect its natural vibration frequency. For a simple spring-mass system, its natural frequency f is given by the following formula: In the formula, k represents the spring constant, and m represents the mass. From this formula, it can be seen that the natural frequency f is inversely proportional to the mass m. Therefore, it can be concluded that the vibration frequency of the glass 1 caused by strong wind is reduced by adding additional mass in the embodiment of the present application.

[0040] 2) The container 3 is provided with a receiving space 301 for holding liquid. When the device is shaken by strong wind, the liquid will produce fluctuations of different frequencies from the glass 1, thereby forming different amplitudes, thereby interfering with the resonance of the glass 1 and reducing the risk of breakage.

[0041] 3) The glass windproof device provided in the embodiment of the present application is only fixed to the glass 1 at one end. Therefore, when vibrating, the lower container 3 as a whole will move forward, backward, left and right. The change in the direction of force will cause different force components to act on different parts of the object, causing more complex vibration behavior, including changes in frequency.

[0042] 4) The glass windshield device provided in the embodiment of the present application is only fixed on the glass 1 at one end, while the container 3 at the bottom naturally hangs by its own gravity, and part of the container 3 contacts the glass 1. There is friction or other forms of energy dissipation mechanism between the contact surfaces, and the change of the damping coefficient affects the resonance frequency. Because the material properties of the device and the glass 1 are different, the elastic modulus and density are different, which also affects the resonance of the glass 1.

[0043] 3. Fatigue damage: Due to the force generated by vibration, the container 3 of the device of the present invention will sway forward, backward, left and right when one end of the top is fixed to the glass 1. The left and right swaying causes the direction of the shear stress generated in the center of the glass 1 to change synchronously, and the front and back swaying affects the normal stress generated in the center of the glass 1. The two prevent the normal stress and shear stress fatigue in the same direction of the glass 1. Taking measures to suppress the synchronous effect of resonance through the resonance phenomenon can significantly reduce the alternating stress acting on the glass 1 and its edge fixed position, thereby reducing the fatigue damage in these areas, and ultimately reducing the risk of glass 1 breaking due to fatigue.

[0044] 4. Momentum conservation and kinetic energy transfer: A moving object has kinetic energy. When it hits glass 1, the kinetic energy will be transferred to glass 1, causing impact force. If the impact force exceeds the strength limit of glass 1, glass 1 will break. When the wind is directed toward glass 1, this device adds mass to glass 1 and part of its area is in contact with glass 1. The kinetic energy of glass 1 will be partially transferred to this device, reducing the impact damage to glass 1 itself.

[0045] In the embodiment of the present application, a container 3 containing liquid is suspended on the glass 1, so as to reduce the probability of glass 1 being damaged in strong wind weather from four aspects: momentum conservation and kinetic energy transfer, pressure difference effect, resonance phenomenon, and fatigue damage, and reduce fatigue damage to the glass 1 and fixed positions of its edges, thereby increasing the service life of the glass 1.

[0046] based on Figure 1 The present specification also provides some specific implementation plans of the method, which are described below.

[0047] Optionally, at least two mutually separated containing spaces 301 are provided on the container 3 ; each containing space 301 is used to contain liquids of different densities; and the volume of the liquid in any containing space 301 is smaller than the volume of the containing space 301 .

[0048] In the embodiment of the present application, each of the containing spaces 301 is used to contain liquids of different densities, for example, water, concentrated salt water, glycerin and other safe liquids, which are not specifically limited here.

[0049] The volumes of the various accommodating spaces 301 on the container 3 may be the same. Preferably, the volumes of the various accommodating spaces 301 are different, so that when the container 3 sways under the action of strong wind, the liquid in each accommodating space 301 generates fluctuations of different frequencies, thereby interfering with the resonance of the glass 1 and reducing the risk of breakage.

[0050] like Figure 1 As shown, three mutually separated cavities can be arranged in the container 3.

[0051] In the embodiment of the present application, at least two mutually separated containing spaces 301 are provided on the container 3. When the container 3 sways under the action of strong wind, due to the different liquid densities in each containing space 301, liquid fluctuations of different frequencies will be generated, thereby forming different amplitudes. This causes the vibration of the device itself to become more complex and irregular, thereby further interfering with the resonance of the glass 1 and reducing the risk of glass 1 breaking.

[0052] Optionally, the container 3 includes at least two sub-containers; each of the sub-containers is provided with the accommodating space 301.

[0053] In an embodiment of the present application, the container 3 includes a plurality of sub-containers provided with a containing space 301. The containing space in each of the sub-containers can be used to hold liquids of the same density or liquids of different densities. The containing space 301 on the sub-container can be an open space or a closed space (i.e., a cavity). The volume of the containing space 301 on each of the sub-containers can be the same. Preferably, the volume of the containing space 301 on each of the sub-containers is different, so that when each sub-container sways under the action of strong wind, the liquid in each containing space 301 produces fluctuations of different frequencies, thereby interfering with the resonance of the glass 1 and reducing the risk of breakage.

[0054] In the embodiment of the present application, when the glass 1 vibrates under the action of strong wind, each sub-container will be displaced and swayed forward, backward, left and right. The change in the direction of force will cause different force components to act on different parts of the glass 1, causing more complex vibration behavior, thereby further interfering with the resonance of the glass 1 and reducing the risk of the glass 1 breaking.

[0055] Optionally, the container 3 includes at least two sub-containers distributed up and down; the uppermost sub-container is suspended below the first connecting structure 2; and each sub-container is suspended below the sub-container above it.

[0056] In the embodiment of the present application, the container 3 may include a string of multiple sub-containers connected end to end.

[0057] In the embodiment of the present application, the lower sub-container is suspended below the upper sub-container by a rope (a rope, a chain, a spring, an elastic band) or the like.

[0058] In the embodiment of the present application, when the glass 1 vibrates under the action of strong wind, each sub-container will be displaced and swayed forward, backward, left and right. The change in the direction of force will cause different force components to act on different parts of the glass 1, causing more complex vibration behavior, thereby further interfering with the resonance of the glass 1 and reducing the risk of the glass 1 breaking.

[0059] In the embodiment of the present application, if each of the sub-containers is fixedly connected to the sub-container above it, the container 3 can be regarded as having a plurality of accommodating spaces 301, which will not be described in detail herein.

[0060] Optionally, the vertical cross-sectional area of ​​the accommodating space 301 is smaller than its horizontal cross-sectional area.

[0061] In the embodiment of the present application, after the liquid is placed in the containing space 301, since the vertical cross-sectional area of ​​the containing space 301 is smaller than its horizontal cross-sectional area, the liquid is relatively shallow, which helps to increase the amplitude of the liquid fluctuation, thereby further interfering with the resonance of the glass 1 and reducing the risk of the glass 1 breaking.

[0062] Optionally, the device further comprises a second connection structure 4 for suspending the container 3 below the first connection structure 2; the second connection structure 4 comprises an elastic connection structure.

[0063] In the embodiment of the present application, the second connection structure 4 may include an elastic connection structure for suspending the container 3 below the first connection structure 2 .

[0064] In the embodiment of the present application, the elastic connection structure may be a tension spring or an elastic band.

[0065] In the embodiment of the present application, when the container 3 sways under the action of strong wind, not only will the liquid in the container 3 produce fluctuations of different frequencies from the glass 1, but the container 3 as a whole will also vibrate under the action of the elastic connection structure, thereby further interfering with the resonance of the glass 1 and reducing the risk of breakage.

[0066] Optionally, the first connecting structure 2 includes an adhesive structure or a suction cup structure.

[0067] In the embodiment of the present application, the first connecting structure 2 can be used to detachably connect the glass windshield device to the glass 1, and can be an adhesive hook or a suction cup hook.

[0068] In the embodiment of the present application, the glass windproof device can be connected to the glass 1 by an adhesive structure or a suction cup structure, and can be easily disassembled after strong wind weather. The structure is simple and easy to use.

[0069] Optionally, the accommodating space 301 is a closed cavity provided on the container 3 .

[0070] In the embodiment of the present application, the accommodating space 301 is a closed cavity provided on the container 3, which can prevent liquid in the glass windshield device from splashing during installation, use, and disassembly.

[0071] Optionally, the cavity contains at least two liquids with different densities and that are immiscible with each other.

[0072] In an embodiment of the present application, at least two liquids with different densities and immiscible with each other are contained in the cavity, and these liquids will be stratified in the cavity when left at rest. After the container 3 is swung, due to the different densities of the liquids, liquid fluctuations of different frequencies will be generated, thereby forming different amplitudes. At the same time, energy will be consumed at the contact surfaces of these liquids, reducing the risk of glass 1 breaking. In addition, if the liquid in the cavity is filled too full, it is not conducive to the fluctuation of the liquid. By containing at least two liquids with different densities and immiscible with each other in the cavity, even if the liquid in the cavity is filled relatively full, fluctuations will be generated at the junction of the two liquids.

[0073] Optionally, when at least two liquids with different densities and immiscible with each other are contained in the accommodation space 301, a pigment different from that of the other liquids is added to at least one of the liquids, thereby enhancing the ornamental value of the glass windshield device.

[0074] Optionally, the cavity contains liquid and a lightweight object; the density of the lightweight object is lower than that of the liquid.

[0075] In the embodiment of the present application, the lightweight object may be foam, a hollow plastic ball, or the like.

[0076] In the embodiment of the present application, the lightweight object can be set to have a decorative shape or color, so as to enhance the ornamental value of the glass windshield device.

[0077] In the embodiment of the present application, if the liquid in the cavity is filled too full, it is not conducive to the liquid to generate fluctuations. By additionally arranging a lightweight object in the cavity, even if the liquid in the cavity is filled relatively full, the vibration of the lightweight object absorbs energy, thereby improving the usability of the glass windshield device.
