Description

Technical Field

[0001] The present invention belongs to the technical field of ventilation and air conditioning, and particularly relates to an adaptive wind-resistant and vibration-damping louver unit capable of restraining all louvers. Background Art

[0002] Building structures often need to ventilate and regulate air flow with the external environment through louvers. For the ventilation systems of large building structures (such as the ventilation openings at the top of large factories or large exhaust ducts), the louver sizes required are usually large. In a strong wind environment, the high-speed environmental wind flowing around the relatively large-sized louvers is extremely likely to induce vibration. Long-term vibration will cause the louver structure to loosen or even fall off, affecting the safety of the ventilation device and its air conditioning capacity.

[0003] Currently, the louver blades mostly rely on a driving mechanism to achieve synchronous opening and closing of the louvers, and the driving mechanism and the rotating shaft provide support for the louvers. There is no effective restraint for the vibration of the louvers, especially for the effective restraint of the vibration of all the louvers of the louver window simultaneously. Existing vibration-damping solutions (such as vibration-damping belts or elastic limiters) can only locally suppress some louvers, and cannot effectively suppress the vibration of the end louvers of the louver window, resulting in the inability of existing vibration-damping solutions to meet the overall stability requirements of all the louvers of the louver window under different wind pressures. Therefore, there is an urgent need for a vibration-damping structure that can adapt to changes in wind pressure and synchronously restrain all louvers, while ensuring the ventilation and air conditioning functions, and improving the wind resistance and operation reliability of the louver window.

[0004] Chinese Utility Model Patent CN201688722U, an anti-freezing device for an automatically opening and closing wind baffle of a cooling tower, describes an adjustable windbreak wall, including several wind baffle synchronous rotation opening and closing units. The driving wheel of the synchronous driving component is installed on the lower rotating pin at the lower end of any one wind baffle, and all the wind baffles are connected to each other through a synchronous rotation mechanism. The driving wheel drives the synchronous rotation mechanism. Between two adjacent window panes, the upper and lower corresponding wind baffles are fixedly connected into one body through a cross-connecting plate. All the wind baffles are driven by the synchronous driving component to rotate synchronously. In the above structure, the cross-connecting plate between the upper and lower wind baffles of the window panes is only used to drive the synchronous rotation of the wind baffles between different window panes. In a strong wind environment, the incoming air flow will cause the wind baffles to shake, vibrate, and even cause the blades to fall off.

[0005] To achieve the vibration suppression effect at a certain opening degree of the louvers, Chinese invention patent application CN118066920A proposes a louver with an external air suction vibration suppression chain device. By using the external air suction vibration suppression chain device installed between the left and right frames of the louver, a lateral pre-tightening force is given to the blades, thereby suppressing the vibration of the louver blades. The self-weight of the vibration suppression chain is relatively large, which can also effectively prevent its fluttering and improve the safety of the louver. The upper and lower fixing devices of the external air suction vibration suppression chain device are respectively located at the upper and lower ends of the louver, and there is no fixed connection with the louvers. It is only attached to the louvers by the action of external air suction, and the contact constraint on the blades is unilateral, that is, the blades are constrained by pressure. Due to the influence of wind pressure on the external air suction vibration suppression chain device, the displacement at the middle position is the largest, while the two ends are in a tension state and the displacement along the wind direction is smaller. Especially the upper and lower ends are fixed points, which leads to the external air suction vibration suppression chain device mainly adsorbing on the louvers at the middle position, resulting in almost no vibration suppression effect on the louvers in the upper and lower end areas and unable to achieve the coordinated constraint of all louvers. And when the louvers are at different opening degrees, it is necessary to manually adjust the length of the external air suction vibration suppression chain through the ratchet tensioning structure of its lower fixing device, which reduces the convenience of the vibration suppression work. Summary of the Invention

[0006] To solve the above-mentioned technical problems, the present invention proposes an adaptive wind-resistant and vibration-suppressing louver unit that can constrain all louvers. A flexible constraint is formed by fixedly connecting the adaptive wind-resistant and vibration-suppressing device to the two leftmost and rightmost louvers of the louver unit, solving the problem that there is almost no vibration suppression effect on the louvers at both ends mentioned above. And through the unilateral contact constraint formed by the adaptive wind-resistant and vibration-suppressing device on the middle louvers and the two-force member constraint formed by rigid link hinges between adjacent louver units, the coordinated constraint of all louvers of the louver unit is realized, thereby improving the wind-resistant and vibration-suppressing ability of all louvers of the louver unit. At the same time, the adaptive wind-resistant and vibration-suppressing device can move synchronously with the louvers and maintain the adsorption state with the louvers.

[0007] The specific solution of the present invention for solving the above-mentioned existing problems is as follows: An adaptive wind-resistant and vibration-suppressing louver unit that can constrain all louvers, including a louver unit, a driving component, and an adaptive wind-resistant and vibration-suppressing 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 side or the windward side of the louver unit; the adaptive wind-resistant and vibration-suppressing device is an adaptive flexible adsorption belt with a certain length and width and is arranged on the windward side of the louver unit; both ends of the adaptive flexible adsorption belt are fixedly connected to the leftmost louver and the rightmost louver of the louver unit respectively, and the middle part of the adaptive flexible adsorption belt is adsorbed on the middle louvers in an adaptive form through the wind pressure formed by the incoming air on the windward side.

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

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

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

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

[0012] The thickness of the solid flexible cloth band is not less than 1.5 mm, and the width is not less than 3 cm; the wall thickness of the hollow flexible cloth 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 band is a hollow flexible cloth sleeve, further N anti-wind and vibration suppression chains may be included, N≥1; when N = 1, the anti-wind and vibration suppression chain penetrates through the hollow of the hollow flexible cloth sleeve.

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

[0015] The anti-wind and vibration suppression chain is a flexible metal chain or a high-strength fiber rope, having high tensile strength and bendability; both ends of the anti-wind and vibration suppression chain are fixedly connected to both ends of the hollow flexible cloth sleeve.

[0016] Further, a rigid connecting rod may be used to hingedly connect the rightmost louver of the left louver window unit and the leftmost louver of the right louver window unit in two adjacent louver window units on the left and right to form a two-force member constraint to balance the pulling force generated by the adaptive anti-wind and vibration suppression device on the outermost louver towards the middle position of the louver window unit.

[0017] Compared with the prior art, the beneficial effects of the present invention are: an adaptive wind-resistant and vibration-suppressing shutter unit that can constrain all shutters, an adaptive wind-resistant and vibration-suppressing device is arranged on the windward side of the shutter unit, which is an adaptive flexible adsorption belt; the two ends of the adaptive flexible adsorption belt are respectively fixedly connected to the windward edges of the leftmost shutter and the rightmost shutter of the shutter unit, and under the action of the incoming wind pressure, the adaptive flexible adsorption belt withstands the wind pressure and is adsorbed on the middle shutter in an adaptive manner; the adaptive flexible adsorption belt generates a pulling force between the leftmost shutter and the rightmost shutter, forming a flexible constraint on the leftmost shutter and the rightmost shutter, converting the incoming wind pressure on the middle shutter into a pressure applied to the middle shutter, forming a unilateral contact constraint, and combining the two constraint methods to achieve effective coordinated constraint of all shutters of the shutter unit, thereby improving the wind-resistant and vibration-suppressing capabilities of all shutters and weakening the vibration and shaking of the shutters caused by strong winds.

[0018] Furthermore, the adaptive flexible adsorption belt is composed of a hollow flexible cloth sleeve and N anti-wind and vibration suppression chains running through the hollow core, which increases the stability of the adaptive flexible adsorption belt, prevents it from fluttering at will in strong winds, and reduces the friction loss of the hollow flexible cloth sleeve; when N ≥ 2, the N non-intersecting anti-wind and vibration suppression chains can stretch the hollow flexible cloth sleeve in the width direction to avoid deformation of the adaptive flexible adsorption belt due to incoming wind pressure, thereby increasing the windward area of ​​the adaptive flexible adsorption belt, enhancing the flexible constraint force and the unilateral contact constraint force, and thus improving the anti-wind and vibration suppression effect of the blinds; further, the rightmost blind of the left blind unit and the leftmost blind of the right blind unit in the two adjacent blind units on the left and right are hinged by a rigid connecting rod to form a two-force component constraint, balancing the pulling force generated by the adaptive anti-wind and vibration suppression device on the outermost blind toward the middle position of the blind unit, so that the force on the outermost blind is more balanced, further enhancing the anti-wind and vibration suppression ability of the blinds.

The change or adjustment of their relative relationships, without substantial change in the technical content, should also be regarded as the scope within which the present invention can be implemented.

[0030] The present invention provides an adaptive wind-resistant and vibration-suppressing shutter unit capable of constraining all shutters, comprising a shutter unit 3, a driving assembly 5 and an adaptive wind-resistant and vibration-suppressing device, characterized in that: the shutter unit 3 comprises a window frame 1 and M shutters 2, wherein M ≥ 3 and is an integer; the shutter 2 is hinged on the window frame 1 through rotating shafts arranged at the upper and lower ends thereof; the driving assembly 5 is connected to the M shutters 2 of the shutter unit 3 and is arranged on the leeward side or the windward side of the shutter unit 3; the adaptive wind-resistant and vibration-suppressing device is an adaptive wind-resistant and vibration-suppressing device having a certain length and width. An adaptive flexible adsorption belt 4 is arranged on the windward side of the shutter unit 3; the two ends of the adaptive flexible adsorption belt 4 are respectively fixedly connected to the windward edges of the leftmost shutter 2 and the rightmost shutter 2 of the shutter unit 3, and the middle part of the adaptive flexible adsorption belt 4 is adsorbed on the middle shutter 2 in an adaptive manner through the wind pressure formed by the wind entering from the windward side; further, the rightmost shutter 2 of the left shutter unit 3 and the leftmost shutter 2 of the right shutter unit 3 in the two adjacent shutter units 3 can also be hingedly connected by a rigid connecting rod 6.

[0031] Working principle of adaptive wind resistance and vibration suppression of all fan blades: two ends of the adaptive flexible adsorption belt 4 are respectively fixedly connected to the vertical edges of the windward side of the leftmost and rightmost louvers 2 of the shutter unit 3 when the shutter unit 3 is in the open state, and under the action of the incoming wind pressure, the adaptive flexible adsorption belt 4 is adaptively adsorbed on the middle louver 2; the adaptive flexible adsorption belt 4 generates a pulling force between the leftmost louver 2 and the rightmost louver 2, forming a flexible constraint on the leftmost louver 2 and the rightmost louver 2, converting the incoming wind pressure on the middle louver 2 into a pressure applied to the louver 2, forming a unilateral contact constraint, thereby realizing effective coordinated constraint of the M louvers 2 of the shutter unit 3, improving the anti-wind and vibration suppression ability of the louver 2 itself, and weakening the vibration and shaking of the louver 2 caused by strong wind.

[0032] The further adaptive flexible adsorption belt 4 is composed of a hollow flexible cloth cover 403 and N wind-resistant and vibration-suppressing chains 402 running through the hollow part, which can increase the stability of the adaptive flexible adsorption belt 4 so that it will not flutter at will in strong winds, reduce the friction loss of the adaptive flexible adsorption belt 4, and further improve the wind-resistant and vibration-suppressing effect of the blinds 2.

[0033] When N≥2, when N anti-wind and vibration suppression chains 402 are arranged non-intersectingly, the hollow flexible cloth sleeve 403 can be expanded in the width direction to prevent the adaptive flexible adsorption belt from being deformed due to the incoming wind pressure, thereby increasing the windward area of ​​the adaptive flexible adsorption belt 4, enhancing the flexible constraint force and the unilateral contact constraint force, and further improving the anti-wind and vibration suppression effect of the blinds 2.

[0034] Furthermore, the rightmost louver 2 of the left louver unit 3 and the leftmost louver 2 of the right louver unit 3 in the adjacent left and right louver units 3 are hinged and connected by a rigid connecting rod 6 to form a two-force member constraint, balancing the tensile force generated by the flexible adsorption belt 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 suppression ability of the louver 2.

[0035] Principle of movement of the louver unit 3: The left-right horizontal movement of the driving rod 501 drives M connecting rods 502 to rotate around the corresponding M rotating shafts respectively, thereby realizing the synchronous rotation of M louvers 2 around their corresponding rotating shafts; Since the two ends of the adaptive flexible adsorption belt 4 are respectively fixedly connected to the vertical edges of the windward sides of the leftmost louver 2 and the rightmost louver 2 of the louver unit 3 in the open state, when the M louvers 2 rotate synchronously, the adaptive flexible adsorption belt 4 moves together with the rotation of the louvers 2, and the distance between the two ends of the adaptive flexible adsorption belt 4 does not change with the change of the opening degree of the louvers 2, that is, the length of the adaptive flexible adsorption belt 4 always adapts to the span requirements of the louver unit 3 at different opening degrees. Therefore, it is ensured that the adaptive flexible adsorption belt 4 always adheres to the louvers 2 in an adaptive form at different opening degrees of the louver unit 3.
