Description

Technical Field

[0001] This application relates to the field of wind protection technology, specifically to a windproof glass device. Background Technology

[0002] Typhoons, as a natural disaster, possess considerable destructive power, especially in coastal areas. The frequent occurrence of typhoons poses a significant challenge to residents' daily lives and property safety. Whenever a typhoon warning is issued, residents anxiously prepare countermeasures to minimize potential damage. However, due to the unpredictable and sudden nature of typhoons, coupled with economic considerations, the window designs of most residential buildings do not adequately consider typhoon resistance. In such cases, residents often resort to temporary measures to protect their windows, such as applying tape to the glass or installing wooden boards on the outside, hoping to reduce the risk of glass breakage during a typhoon.

[0003] While these methods offer some protection, they also have numerous inconveniences and limitations. First, these measures need to be dismantled after the typhoon, increasing the workload and time-consuming process for residents. Second, their reliability is low; they offer more psychological comfort than genuine safety guarantees. Furthermore, because these measures need to be prepared in advance of the typhoon, their utilization rate is low, and residents often cannot take these measures in time due to time constraints.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Application Overview

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

[0023] 1. Conservation of Momentum and Transfer of Kinetic Energy: During typhoons or severe convective weather, high-speed objects (such as flying sand and stones) carry a large amount of kinetic energy. When these objects collide with glass, according to the law of conservation of momentum, their kinetic energy is rapidly 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: During typhoons or severe convective weather, rapid changes in wind speed can lead to an imbalance in indoor and outdoor pressure. The air pressure is lower on the side with faster wind speeds, while the interior of a building, being relatively enclosed, maintains higher pressure. This pressure difference can create tensile stress on the glass. If the stress exceeds the elastic limit of the glass, it may break due to the stress.

[0025] 3. Resonance Phenomenon: Under strong winds, 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, significantly increasing the amplitude of the glass vibration and raising the likelihood of damage.

[0026] 4. Fatigue damage: Prolonged exposure to strong winds, even if the wind speed is not high enough to directly cause the glass to break, can still cause fatigue damage. This damage is a cumulative effect, especially when there are already microcracks in the glass. These cracks will gradually expand under repeated wind pressure, eventually leading to the glass breaking.

[0027] To address the aforementioned issues, this embodiment suspends a container filled with liquid on the glass. This effectively reduces the risk of glass breakage in strong winds by addressing four aspects: conservation of momentum and kinetic energy transfer, pressure difference effect, resonance phenomenon, and fatigue damage. It also reduces fatigue damage to the glass and its fixed edges, thereby extending the glass's service life.

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

[0029] Exemplary device

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

[0031] In this embodiment, the first connecting structure 2 is used to connect the glass windproof device and the glass 1. The first connecting structure 2 can be detachably connected to the glass 1. Furthermore, the first connecting structure 2 can be detachably connected to the central region of the glass 1.

[0032] In this embodiment, the container 3, suspended below the first connecting structure 2, 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 this embodiment, the liquid-containing space 301 on the container 3 can be an open space or a cavity located inside the container 3. The number of the liquid-containing spaces 301 can be set as needed.

[0034] In this embodiment of the application, the container 3 may be provided with a cavity for holding liquid. The number of cavities can be set as needed. The cavities can be arranged vertically, horizontally, or randomly. There is no limit to the volume of the cavities.

[0035] In this embodiment of the application, the container 3 can be made of a tough, impact-resistant, chemically resistant, and non-toxic material, such as plastics (PVC, PP, nylon, Teflon, etc.) or resins.

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

[0037] 1. Regarding the pressure difference effect: The glass windproof device provided in this application embodiment can apply an inward pulling force and a downward pressure at the center of the inner side of the glass 1 to counteract the outward pulling force formed by the low external air pressure. The two external forces are the weight of the glass windproof device itself, which reduces the risk of the glass 1 breaking due to the imbalance of internal and external pressure.

[0038] II. Regarding the resonance phenomenon:

[0039] 1) Regarding vibrations caused by strong winds: The glass windproof device provided in this application can apply an inward pulling force and a downward pressure at the center of the inner side of the glass 1. These two external forces change the mass distribution of the glass 1 itself. When the mass of a vibrating system increases, it affects 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 is the mass. This formula shows that the natural frequency f is inversely proportional to the mass m. Therefore, it can be concluded that in this embodiment, adding additional mass reduces the vibration frequency of glass 1 caused by strong winds.

[0040] 2) The container 3 is provided with a liquid-containing space 301. When the device sways under strong winds, the liquid will produce fluctuations at a different frequency than the glass 1, thus forming different amplitudes. This interferes with the resonance of the glass 1, reducing the risk of breakage.

[0041] 3) The glass windproof device provided in this application embodiment is only fixed to the glass 1 at the top end. Therefore, when vibrating, the lower container 3 will move back and forth and sway left and right. The change in the direction of force will cause different force components to act on different parts of the object, resulting in more complex vibration behavior, including frequency changes.

[0042] 4) The glass windproof device provided in this embodiment is fixed to the glass 1 at only one end, while the lower container 3 hangs naturally under its own weight, with a portion of the container 3 in contact with the glass 1. Friction or other forms of energy dissipation mechanisms exist between the contact surfaces, causing changes in the damping coefficient and thus affecting the resonant frequency. Because the properties of this device and glass 1 are different, their elastic modulus and density are also different, which also affects the resonance of glass 1.

[0043] III. Fatigue Damage: Due to the force generated by vibration, when the top end of the device is fixed to the glass 1, the container 3 will experience back-and-forth and left-and-right displacement and swaying. The left-and-right swaying causes the direction of the shear stress generated at the center of the glass 1 to change synchronously, and the back-and-forth swaying affects the normal stress generated at the center of the glass 1. Both prevent fatigue of the glass 1 under normal stress and shear stress in the same direction. By taking measures to suppress the synchronous effect of resonance through the resonance phenomenon, the alternating stress acting on the glass 1 and its fixed edge position can be significantly reduced, thereby mitigating fatigue damage in these areas and ultimately reducing the risk of the glass 1 breaking due to fatigue.

[0044] IV. Conservation of Momentum and Transfer of Kinetic Energy: A moving object possesses kinetic energy. Upon impact with glass 1, this kinetic energy is transferred to glass 1, creating an impact force. If the impact force exceeds the strength limit of glass 1, glass 1 will shatter. When the wind is directed towards glass 1, this device adds mass to glass 1 and has a portion of its surface in contact with it. Consequently, some of the kinetic energy of glass 1 is transferred to this device, reducing the impact damage to glass 1.

[0045] In this embodiment, a container 3 containing liquid is suspended on the glass 1. This reduces the probability of glass 1 breaking in strong winds by addressing four aspects: conservation of momentum and kinetic energy transfer, pressure difference effect, resonance phenomenon, and fatigue damage. It also reduces fatigue damage to the glass 1 and its fixed edge positions, thereby increasing the service life of the glass 1.

[0046] based on Figure 1 The embodiments of this specification also provide some specific implementation schemes of the method, which are described below.

[0047] Optionally, the container 3 is provided with at least two mutually spaced containment spaces 301; each containment space 301 is used to contain liquids of different densities; the volume of liquid in any containment space 301 is smaller than the volume of that containment space 301.

[0048] In this embodiment, each of the accommodating spaces 301 is used to accommodate liquids of different densities, such as water, concentrated salt water, glycerin, and other safe liquids, without any specific limitations.

[0049] The volume of each containing space 301 on the container 3 can be the same. Preferably, the volumes of each containing space 301 are different, so that when the container 3 sways under strong winds, the liquid in each containing space 301 will fluctuate at different frequencies, thereby interfering with the resonance of the glass 1 and reducing the risk of breakage.

[0050] like Figure 1 As shown, the container 3 can be provided with three mutually spaced cavities.

[0051] In this embodiment, the container 3 is provided with at least two spaced-apart containment spaces 301. When the container 3 sways under strong winds, the different liquid densities within each containment space 301 will generate liquid fluctuations of different frequencies, resulting in different amplitudes. This makes the vibration of the device itself more complex and irregular, further interfering with the resonance of the glass 1 and reducing the risk of glass 1 breakage.

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

[0053] In this embodiment, the container 3 includes multiple sub-containers each having a receiving space 301. Each sub-container can hold liquids of the same density or liquids of different densities within its receiving space. The receiving space 301 on each sub-container can be an open space or a closed space (i.e., a cavity). The volume of the receiving spaces 301 on each sub-container can be the same. Preferably, the volumes of the receiving spaces 301 on each sub-container are different, so that when each sub-container sways under strong winds, the liquid in each receiving space 301 will fluctuate at different frequencies, thereby interfering with the resonance of the glass 1 and reducing the risk of breakage.

[0054] In this embodiment, when glass 1 vibrates under strong wind, each sub-container will sway back and forth and left and right. The change in the direction of force will cause different force components to act on different parts of glass 1, resulting in more complex vibration behavior, thereby further interfering with the resonance of glass 1 and reducing the risk of glass 1 breaking.

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

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

[0057] In this embodiment, the lower sub-container is suspended below the upper sub-container by a rope-like object (rope, chain, spring, elastic band, etc.).

[0058] In this embodiment, when glass 1 vibrates under strong wind, each sub-container will sway back and forth and left and right. The change in the direction of force will cause different force components to act on different parts of glass 1, resulting in more complex vibration behavior, thereby further interfering with the resonance of glass 1 and reducing the risk of glass 1 breaking.

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

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

[0061] In this embodiment of the 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 liquid fluctuation, thereby further interfering with the resonance of glass 1 and reducing the risk of glass 1 breaking.

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

[0063] In this embodiment of the application, the second connection structure 4 may include an elastic connection structure that suspends the container 3 below the first connection structure 2.

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

[0065] In this embodiment, when the container 3 sways under strong winds, not only will the liquid inside the container 3 produce fluctuations at a different frequency than 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 connection structure 2 includes an adhesive structure or a suction cup structure.

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

[0068] In this embodiment, the adhesive structure or suction cup structure can connect the glass windproof device to the glass 1 and can be easily disassembled after strong winds. The structure is simple and easy to use.

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

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

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

[0072] In this embodiment, the cavity contains at least two immiscible liquids of different densities. When stationary, these liquids will separate into layers within the cavity. When the container 3 is shaken, the different densities of the liquids will generate liquid fluctuations of varying frequencies, resulting in different amplitudes. Simultaneously, energy is consumed at the contact surfaces of these liquids, reducing the risk of glass 1 breaking. Furthermore, if the cavity is overfilled, it hinders the generation of liquid fluctuations. By containing at least two immiscible liquids of different densities within the cavity, fluctuations occur at the interface between the two liquids even when the cavity is relatively full.

[0073] Optionally, if the containing space 301 contains at least two liquids of different densities and immiscible, at least one liquid contains a pigment different from the other liquids. This enhances the aesthetic appeal of the glass windproof device.

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

[0075] In this embodiment of the application, the lightweight object may be foam, hollow plastic ball, etc.

[0076] In this embodiment, the lightweight object can be configured with a decorative shape or color to enhance the aesthetics of the glass windproof device.

[0077] In this embodiment, if the liquid inside the cavity is too full, it is not conducive to the liquid undulating. By additionally placing a lightweight object inside the cavity, even when the cavity is relatively full, the vibration of the lightweight object absorbs energy, improving the usability of the glass windproof device.
