Description

Technical Field

[0001] This utility model belongs to the field of ventilation and air conditioning technology, and specifically relates to an adaptive wind-resistant and vibration-damping louver unit that can constrain all louvers. Background Technology

[0002] Building structures often require louvers for ventilation and airflow regulation with the external environment. For ventilation systems in large buildings (such as roof vents in large factories or large exhaust ducts), the required louver size is usually large. In windy conditions, the high-speed airflow around large louvers can easily induce vibration. Long-term vibration can cause the louver structure to loosen or even fall off, affecting the safety of the ventilation system and its air conditioning capabilities.

[0003] Currently, most louver blades rely on drive mechanisms to achieve synchronous opening and closing, and these mechanisms and rotating shafts provide support for the louvers. There is no effective constraint on louver vibration, especially effective constraint on the vibration of all louvers simultaneously. Existing vibration suppression solutions (such as vibration damping strips or elastic limiters) can only locally suppress some louvers, failing to effectively suppress the vibration of the louvers at the ends of the louver. This results in existing vibration suppression solutions being unable to meet the overall stability requirements of all louvers under different wind pressures. Therefore, there is an urgent need for a vibration suppression structure that can adapt to changes in wind pressure and synchronously constrain all louvers, improving the wind resistance and operational reliability of louvers while ensuring ventilation and air conditioning functions.

[0004] Chinese utility model patent CN201688722U, "Automatic Opening and Closing Wind Deflector Antifreeze Device for Cooling Towers," describes an adjustable wind deflector wall, comprising several wind deflector synchronously rotating opening and closing units. The driving wheel of the synchronous drive component is mounted on the lower pivot pin at the bottom of any wind deflector. All wind deflectors are interconnected via a synchronous rotation mechanism. The driving wheel drives the synchronous rotation mechanism. Between adjacent window panes, corresponding upper and lower wind deflectors are fixedly connected as a single unit via a bridge connecting plate. All wind deflectors are driven to rotate synchronously by the synchronous drive component. In this structure, the bridge connecting plate between the two wind deflectors in the upper and lower window panes is only used to drive the synchronous rotation of wind deflectors between different window panes. However, in windy conditions, the incoming airflow can cause the wind deflectors to sway, vibrate, and even have blades fall off.

[0005] To achieve vibration suppression at a certain opening degree, China applied for utility model patent CN118066920A, proposing a louver with an external suction vibration suppression chain device. By using the external suction vibration suppression chain device installed between the left and right frames of the louver, a lateral preload is applied to the blades, thereby suppressing the vibration of the louver blades. The vibration suppression chain has a large self-weight, which can also effectively prevent it from swaying and improve the safety of the louver. The upper and lower fixing devices of the external suction vibration suppression chain device are located at the upper and lower ends of the louver, respectively. They are not fixedly connected to the louvers, but are attached to the louvers by external suction. The blades are constrained by pressure on one side. Because the external suction vibration damping chain device is affected by wind pressure, the middle position has the largest displacement, while the two ends are under tension and have smaller displacement along the wind direction. In particular, since the upper and lower ends are fixed points, the external suction vibration damping chain device mainly adheres to the louvers in the middle position, resulting in almost no vibration damping effect on the louvers in the upper and lower end areas, and failing to achieve coordinated constraint of all louvers. Furthermore, for different louver openings, the length of the external suction vibration damping chain needs to be manually adjusted through the ratchet tensioning structure of its lower fixing device, which reduces the convenience of vibration damping work. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention proposes an adaptive wind-resistant and vibration-damping louver unit that can constrain all louvers. An adaptive wind-resistant and vibration-damping device is fixedly connected to the leftmost and rightmost louvers of the louver unit to form a flexible constraint, solving the problem that the louvers at both ends have almost no vibration-damping effect. Furthermore, the adaptive wind-resistant and vibration-damping device forms a unilateral contact constraint on the middle louver, and the rigid connecting rods between adjacent louver units create a two-force component constraint, achieving coordinated constraint of all louvers in the louver unit, thereby improving the wind-resistant and vibration-damping capability of all louvers. Simultaneously, the adaptive wind-resistant and vibration-damping device can move synchronously with the louvers and maintain an adsorption state with them.

[0007] The specific solution of this utility model to solve the above-mentioned existing problems is as follows: an adaptive wind-resistant and vibration-damping louver unit that can constrain all louvers, including a louver unit, a driving component, and an adaptive wind-resistant and vibration-damping device, characterized in that: the louver unit includes a window frame and M louvers, where M≥3 and is an integer; the driving component is connected to the M louvers of the louver unit and is arranged on the leeward or windward side of the louver unit; the adaptive wind-resistant and vibration-damping device is an adaptive flexible adsorption strip of a certain length and width, arranged on the windward side of the louver unit; the two ends of the adaptive flexible adsorption strip are respectively fixedly connected to the leftmost and rightmost louvers of the louver unit, and the middle part of the adaptive flexible adsorption strip is adsorbed onto the middle louver in an adaptive manner by the wind pressure formed by the wind intake on the windward side.

[0008] The window frame includes an upper horizontal frame and a lower horizontal frame, and may further include a left vertical frame and a right vertical frame; the louvers are hinged to the upper and lower horizontal frames via pivots arranged at their upper and lower ends.

[0009] The drive assembly includes a drive rod and a connecting rod; the drive rod provides driving force; one end of the connecting rod is fixedly connected to the louver, and the other end is hinged to the drive rod.

[0010] One end of the adaptive flexible adsorption strip is fixedly connected to the windward edge of the leftmost louver of the louver unit, and the other end is fixedly connected to the windward edge of the rightmost louver of the louver unit; the windward edge is the vertical edge on the windward side when the louver is open.

[0011] The adaptive flexible adsorption strip is a solid flexible fabric strip or a hollow flexible fabric sleeve, made of polypropylene, nylon, polyester, polyethylene, aramid or other coated fabrics; the length of the adaptive flexible adsorption strip is greater than the axial distance between the leftmost and rightmost louvers of the louver unit.

[0012] The thickness of the solid flexible fabric strip is not less than 1.5 mm and the width is not less than 3 cm; the wall layer thickness of the hollow flexible fabric sleeve is not less than 1.2 mm and the cross-sectional perimeter is not less than 6 cm.

[0013] When the adaptive flexible adsorption belt is a hollow flexible fabric cover, it may further include N wind-resistant and vibration-damping chains, where N≥1; when N=1, the wind-resistant and vibration-damping chains penetrate through the hollow of the hollow flexible fabric cover.

[0014] When N≥2, the N wind-resistant and vibration-damping chains are arranged in a non-intersecting manner and run through the hollow of the hollow flexible cloth sleeve to increase the windward area of ​​the adaptive wind-resistant and vibration-damping device.

[0015] The wind-resistant and vibration-damping chain is a flexible metal chain or a high-strength fiber rope, which has the characteristics of high tensile strength and bendability; the two ends of the wind-resistant and vibration-damping chain are respectively fixedly connected to the two ends of the hollow flexible cloth sleeve.

[0016] Furthermore, a rigid connecting rod can be used to hinge the rightmost louver of the left louver unit to the leftmost louver of the right louver unit in two adjacent louver units, forming a two-force component constraint to balance the tension generated by the adaptive wind-resistant and vibration-damping device on the outermost louver towards the middle position of the louver unit.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: An adaptive wind-resistant and vibration-damping louver unit that can constrain all louvers has an adaptive wind-resistant and vibration-damping device arranged on the windward side of the louver unit, which is an adaptive flexible adsorption strip. The two ends of the adaptive flexible adsorption strip are respectively fixedly connected to the windward edges of the leftmost and rightmost louvers of the louver unit. Under the action of the incoming wind pressure, the adaptive flexible adsorption strip bears the wind pressure and adsorbs onto the middle louver in an adaptive manner. The adaptive flexible adsorption strip generates tension between the leftmost and rightmost louvers, forming a flexible constraint on the leftmost and rightmost louvers. On the middle louver, the incoming wind pressure is converted into pressure applied to the middle louver, forming a unilateral contact constraint. The combination of the two constraint methods achieves effective synergistic constraint of all louvers in the louver unit, thereby improving the wind resistance and vibration-damping ability of all louvers and weakening the vibration and swaying of the louvers caused by strong winds.

[0018] The further adaptive flexible adsorption strip consists of a hollow flexible fabric sleeve and N wind-resistant and vibration-damping chains running through the hollow core. This increases the stability of the adaptive flexible adsorption strip, preventing it from swaying freely in strong winds and reducing frictional wear on the hollow flexible fabric sleeve. When N≥2, the N non-intersecting wind-resistant and vibration-damping chains can expand the width of the hollow flexible fabric sleeve, preventing the adaptive flexible adsorption strip from deforming due to the incoming wind pressure. This increases the windward area of ​​the adaptive flexible adsorption strip, enhances the flexible constraint force and unilateral contact constraint force, and thus improves the wind resistance and vibration damping effect of the louvers. Furthermore, the rightmost louver of the left louver unit and the leftmost louver of the right louver unit are rigidly connected by a connecting rod, forming a two-force constraint. This balances the pulling force exerted by the adaptive wind-resistant and vibration-damping device on the outermost louver towards the center of the louver unit, making the force on the outermost louver more balanced and further enhancing the wind resistance and vibration damping capability of the louvers.

They are not intended to limit the scope of this invention and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, provided they do not affect the effectiveness or purpose of this invention, should still fall within the scope of the technical content disclosed in this invention.

[0030] This utility model provides an adaptive wind-resistant and vibration-damping louver unit that can constrain all louvers, including a louver unit 3, a drive assembly 5, and an adaptive wind-resistant and vibration-damping device. The louver unit 3 includes a window frame 1 and M louvers 2, where M ≥ 3 and is an integer; the louvers 2 are hinged to the window frame 1 via pivots arranged at their upper and lower ends; the drive assembly 5 is connected to the M louvers 2 of the louver unit 3 and is arranged on the leeward or windward side of the louver unit 3; the adaptive wind-resistant and vibration-damping device has a certain length and width. An adaptive flexible adsorption strip 4 is arranged on the windward side of the louver unit 3. The two ends of the adaptive flexible adsorption strip 4 are fixedly connected to the windward edges of the leftmost louver 2 and the rightmost louver 2 of the louver unit 3, respectively. The middle part of the adaptive flexible adsorption strip 4 is adsorbed onto the middle louver 2 in an adaptive manner by the wind pressure formed by the wind intake on the windward side. Furthermore, the rightmost louver 2 of the left louver unit 3 and the leftmost louver 2 of the right louver unit 3 can also be connected by a rigid connecting rod 6.

[0031] The adaptive wind resistance and vibration damping working principle of all fan blades: The two ends of the adaptive flexible adsorption strip 4 are fixedly connected to the vertical edges of the leftmost louver 2 and the rightmost louver 2 in the windward side when they are open in the louver unit 3. Under the action of the incoming air pressure, the adaptive flexible adsorption strip 4 is adsorbed on the middle louver 2 in an adaptive manner. The adaptive flexible adsorption strip 4 generates tension between the leftmost louver 2 and the rightmost louver 2, forming a flexible constraint on the leftmost louver 2 and the rightmost louver 2. It converts the incoming air pressure into pressure applied to the middle louver 2, forming a unilateral contact constraint. This achieves effective coordinated constraint of the M louvers 2 in the louver unit 3, improves the wind resistance and vibration damping ability of the louvers 2, and weakens the vibration and swaying of the louvers 2 caused by strong winds.

[0032] The further adaptive flexible adsorption belt 4 is composed of a hollow flexible cloth sleeve 403 and N wind-resistant and vibration-damping chains 402 running through the hollow, which can increase the stability of the adaptive flexible adsorption belt 4, so that it will not sway randomly in strong winds, reduce the frictional loss of the adaptive flexible adsorption belt 4, and further improve the wind-resistant and vibration-damping effect of the louver 2.

[0033] When N≥2, the N wind-resistant and vibration-damping chains 402 arranged without intersection can expand the width direction of the hollow flexible cloth sleeve 403, avoid deformation of the adaptive flexible adsorption belt due to the wind pressure, thereby increasing the windward area of ​​the adaptive flexible adsorption belt 4, improving the flexible constraint force and the single-sided contact constraint force, and thus improving the wind-resistant and vibration-damping effect of the louver 2.

[0034] Furthermore, the rightmost louver 2 of the left louver unit 3 and the leftmost louver 2 of the right louver unit 3 are connected by a rigid connecting rod 6 to form a two-force component constraint, which balances the pulling force of the flexible adsorption strip 4 on the outermost louver 2 towards the middle position of the louver unit 3, making the force on the outermost louver 2 more balanced and further enhancing the wind resistance and vibration damping ability of the louver 2.

[0035] The movement principle of the venetian blind unit 3: The horizontal movement of the drive rod 501 drives the M connecting rods 502 to rotate around their corresponding M axes, thereby realizing the synchronous rotation of the M venetians 2 around their respective axes; Since the two ends of the adaptive flexible adsorption belt 4 are fixedly connected to the vertical edges of the leftmost and rightmost venetians 2 in the open state, the adaptive flexible adsorption belt 4 moves together with the venetians 2 when the M venetians 2 rotate synchronously. The distance between the two ends of the adaptive flexible adsorption belt 4 does not change with the opening degree of the venetians 2, that is, the length of the adaptive flexible adsorption belt 4 always adapts to the span requirements of the venetian blind unit 3 at different opening degrees. Therefore, it is ensured that the adaptive flexible adsorption belt 4 is always adsorbed on the venetians 2 in an adaptive manner at different opening degrees of the venetian blind unit 3.
