Description
Technical Field
[0001] The utility model belongs to the field of cooling tower shutters, in particular to a shutter with an external air suction vibration suppression chain device. Background Art
[0002] At present, the technology of venetian blinds is still in the development stage. Since the technology of venetian blinds is not yet mature, there are still many problems in the application process of venetian blinds. With the large-scale development of indirect air-cooling towers, the horizontal span of the venetian blinds of the indirect air-cooling triangular air inlet is getting larger and larger. As a result, the thin and long venetian blinds are subjected to excessive internal and external wind pressure at a small opening of 15°~35°, causing large vibrations. The vibration of the venetian blinds is a problem that needs to be solved urgently. The venetian blinds will make a huge noise when vibrating, causing noise pollution. The venetian blinds will also cause other fasteners to loosen while vibrating, and in more serious cases, they will fall off, resulting in the venetian blinds being unable to be used normally, seriously affecting the safety and economy of the venetian blinds.
[0003] China applied for a patent, patent number: 2023102365663, disclosing "A Venetian Blind with a Self-Vibration Suppression Device", including a Venetian Blind and a self-vibration suppression device. The Venetian Blind includes a left side frame, blinds, a right side frame, an upper frame, and a lower frame. The self-vibration suppression device includes a fixing device and a vibration suppression belt. The self-vibration suppression device is installed between the left side frame and the right side frame of the Venetian Blind. With the large-scale development of indirect air-cooling towers, the lateral span of the triangular air inlet louvers of indirect air-cooling cooling is also getting larger and larger. As a result, the thin and long louver blades are subjected to excessive internal and external wind pressure when the opening is small at 15°~35°, causing large vibration. To solve this problem, the utility model patent introduces a louver with a self-vibration suppression device. The force exerted on the vibration suppression belt by the wind pressure gives the thin and long blades a lateral pre-tightening force, thereby effectively suppressing the self-excited vibration of the blades when the louver is small, while not affecting the normal rotation of the blades, reducing the self-excited vibration of the louver while reducing noise, and improving the safety and economy of the louver. Although this utility model solves the vibration problem of large-span louvers, when the ambient wind speed is high, the vibration suppression belt in the self-vibration suppression device will flutter with the wind, aggravating the wear and damage of the vibration suppression belt, causing the vibration suppression belt to be unable to be used normally and having no vibration suppression effect.
[0004] The utility model introduces a Venetian blind with an external suction vibration suppression chain device, which gives the blades a lateral pre-tightening force through the external suction vibration suppression chain, thereby effectively suppressing the vibration of the Venetian blind blades. At the same time, due to the large dead weight of the vibration suppression chain, the external suction vibration suppression chain device can be effectively prevented from fluttering, thereby reducing the vibration of the blinds and the noise, thereby improving the safety of the blinds.
