Technical Field
[0001] This utility model relates to the field of louver vibration damping technology, and in particular to a louver vibration damping device in an air-cooling system. Background Technology
[0002] Based on the characteristics and geographical distribution of China's energy structure, a large portion of my country's thermal power plants are located in the water-scarce and coal-rich northwest region. According to policy guidance and technical requirements, these power plants employ surface-condensing air-cooled systems for turbine exhaust cooling. In both direct and indirect air-cooled systems, due to the large diurnal temperature range, severe winters, and strong winds in the northwest, louvers are necessary to protect the heat exchange tube bundles from freezing. To maintain stable heat exchange and normal water circulation, louvers are installed on the outer side of the tube bundles. The opening and closing of these louvers controls the airflow into the tower.
[0003] In windy weather, the blades of traditional louvers are prone to vibration when the shutters are slightly open, causing excessive noise. Utility Model Content

[0023] Figure 1 This is a schematic diagram of the structure of the louvered vibration damping device in the hollow air cooling system of this utility model; Figure 2 This is a top view of the louvered vibration damping device in the hollow air cooling system of this utility model; Figure 3 This is a schematic diagram showing the installation of the louver vibration damping device on the louvers in the hollow air cooling system of this utility model. Please refer to [link / reference]. Figures 1 to 3 The diagram illustrates a preferred embodiment of a louver vibration damping device in an air-cooled system. This device is for installation on a louver 1 and includes a circular tube assembly, connectors 4, and steel wire ropes 5. The circular tube assemblies are mounted on the louver 1, and two circular tube assemblies are connected by several steel wire ropes 5. Both ends of each steel wire rope 5 are connected to the circular tube assembly via connectors 4, and the steel wire ropes 5 abut against the blades 2 of the louver 1. In this embodiment, see [reference needed]. Figure 3 As shown, the two ends of the circular tube 3 are connected to the two sides of the louver 1. The number of circular tubes 3 can be set as needed. The steel wire rope 5 is placed between two circular tubes 3, and the tension of the steel wire rope 5 can be adjusted through the connector 4 so that the steel wire rope 5 can abut against the blades 2 of the louver 1. By adjusting the tension of the steel wire rope 5, for example, the tighter the steel wire rope 5, the lower the vibration frequency of the blades 2. Adjusting the tension of the steel wire rope 5 can reduce the vibration frequency of the blades 2 and reduce the noise that occurs when the blades 2 vibrate.
[0024] Furthermore, as a preferred embodiment, two wire ropes 5 are provided, and the two wire ropes 5 are arranged crosswise. See also Figure 1 As shown, two round pipes 3 and two steel wire ropes 5 can be grouped together. Several groups can be set according to the size and shape of the louver 1. Adjacent groups can be connected together by connecting plates 6 and bolts 7. For details, please refer to [reference needed]. Figure 2 As shown.
[0025] Furthermore, as a preferred embodiment, the circular tube assembly includes a circular tube 3, a connecting plate 6, and bolts 7. One end of the connecting plate 6 is connected to the circular tube 3, and the other end of the connecting plate 6 is connected to the louver 1 via bolts 7. See also Figure 2As shown, the connecting plate 6 is set in an "L" shape, which makes it easy to cooperate with the bolt 7 and to connect with the outer frame of the louver 1 or the wall, thereby fixing the position of the round tube 3 and facilitating the installation of the steel wire rope 5. The two steel wire ropes 5 can be set crosswise.
[0026] Furthermore, as a preferred embodiment, the wire ropes 5 are provided in two sets, with two wire ropes 5 in each set, and the two wire ropes 5 in each set are arranged in a cross configuration. In other embodiments, the wire ropes 5 can be provided in two sets, which can more stably reduce the vibration frequency of the blade 2 and reduce the noise caused by the vibration of the blade 2.
[0027] Furthermore, as a preferred embodiment, the connector 4 is a turnbuckle, a common structure on the market. The turnbuckle allows for adjustment of the tension of the wire rope 5 and facilitates its installation.
[0028] Furthermore, as a preferred embodiment, it also includes support rods 8, with both ends of the round tube 3 passing through the two support rods 8, and the wire rope 5 located between the two support rods 8. By setting the support rods 8, stable support for the round tube 3 can be achieved. Several mounting holes are opened on the support rods 8, and the round tube 3 passes through the mounting holes, so that the position of the round tube 3 on the support rods 8 can be adjusted, which facilitates the installation of the wire rope 5.
[0029] In use, the two ends of the round tube 3 are installed at the designated positions of the louver 1 through the cooperation of the connecting plate 6 and the bolt 7. Then, the two ends of the steel wire rope 5 are connected to the round tube 3 through the turnbuckle. The tension of the steel wire rope 5 is adjusted by the turnbuckle as needed so that the steel wire rope 5 can contact the blade 2 without affecting the normal opening of the blade 2. When the blade 2 is at a small opening degree, the steel wire rope 5 can press against the blade 2, which can reduce the vibration frequency of the blade 2, thereby reducing the vibration noise of the blade 2.
[0030] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
