[0026] Embodiment

[0027] As Figure 1 、 Figure 2 and Figure 3 shown, the overall assembly of the louver for the combined dry and wet closed tower in this embodiment includes a window frame 1 and a plurality of louver blades 2 evenly spaced from top to bottom. The window frame 1 adopts a rectangular frame structure, and at the same time, the window frame 1 is spliced by extrusion profiles, and the joints are sealed with structural glue to ensure the sealing performance of the joints. The window frame 1 is installed on the corresponding tower frame of the closed tower. In order to improve the sealing performance between the window frame 1 and the tower frame and prevent water leakage and seepage, in this embodiment, the window frame 1 and the tower frame are sealed with a sealing strip, and, as Figure 8As shown in the figure, in order to ensure that the position of the sealing strip is more stable and reliable, in this embodiment, a recessed groove 11 is provided on one side of the window frame 1 that contacts the tower body frame. The cross-section of the groove 11 is an arc-shaped groove or a rectangular groove that matches the sealing strip. One side of the sealing strip is placed in the groove 11, and the other side of the sealing strip protrudes outside the groove 11. A mating groove that cooperates with the sealing strip is provided on one side of the tower body frame that contacts the window frame 1. The other side of the sealing strip is located in the mating groove. When the shutter assembly is installed on the tower body frame, one side of the sealing strip is located in the groove 11 and the other side is located in the mating groove, which can seal the gap between the tower body frame and the window frame 1, and will not shift in position under the limiting action of the groove 11 and the mating groove, making the sealing effect more reliable and stable, and avoiding the occurrence of water seepage and leakage phenomena.

[0028] A number of shutter blades 2 have the same structure. Both ends of each shutter blade 2 are rotatably installed on the window frame 1 through fixing brackets 3. Specifically, as Figure 7 shown, the fixing bracket 3 includes a hinge portion 31, an end plate 32, and side plates 34 connected to the upper and lower sides of the end plate 32. One end of the hinge portion 31 is fixedly connected to the end plate 32, and the other end is hinged to the window frame 1. Specifically, a mounting plate 5 is fixedly connected to the window frame 1, and the connection method is welding or other connection methods in the prior art; the hinge portion 31 is rotatably hinged to the mounting plate 5 through a hinge shaft. The end plate 32 covers the end face of the shutter blade 2, and the shape and size of the end plate 32 match the end face of the shutter blade 2. The side plates 34 respectively cover the upper and lower side faces of the end of the shutter blade 2, and the end plate 32, the side plates 34 and the shutter blade 2 are respectively connected and fastened through fasteners. Specifically, in this embodiment, the fasteners adopt connecting bolts 7, and the end plate 32 and the shutter blade, and the side plates 34 and the shutter blade 2 are respectively connected and fastened through bolts. This connection method is simple to install and has high reliability. A limiting groove 23 is provided on the shutter blade 2. The limiting groove 23 is recessed on the surface of the shutter blade 2 and extends along the length direction of the shutter blade 2 itself. A bending portion 33 that cooperates with the above-mentioned limiting groove 23 is provided on the side plate 34 of the fixing bracket 3. When the fixing bracket 3 is fixedly connected to the end of the shutter blade 2, the bending portion 33 is inserted and matched with the above-mentioned limiting groove 23. With this design, it is convenient for the positioning and cooperation of the fixing bracket 3 and the shutter blade 2 and is convenient for installation; at the same time, it can also limit the freedom degree of the shutter blade 2 in the length direction of the fixing bracket 3 and strengthen the tightness and reliability of the connection between the two.

[0029] As Figure 4 and Figure 5As shown, a plurality of louver blades 2 are all connected to a control assembly 4, and the control assembly 4 is used to control the synchronous unfolding or closing of the plurality of louver blades 2. The control assembly 4 includes a linkage rod 42 and a plurality of connecting rods 41. One ends of the plurality of connecting rods 41 are respectively fixedly connected to the plurality of louver blades 2 in a one-to-one correspondence. Specifically, in this embodiment, it is preferably to fixedly connect the connecting rod 41 and the louver blade 2 by a connecting bolt 7. The other ends of the plurality of connecting rods 41 are all hinged to the linkage rod 42. The axis of the linkage rod 42 is perpendicular to the length direction of the louver blade 2, and the plurality of louver blades 2 are distributed in parallel, and the plurality of connecting rods 41 are also distributed in parallel. The hinge structure between the connecting rod 41 and the linkage rod 42 is prior art and will not be elaborated here. One end of the linkage rod 42 is connected to a driving mechanism. By driving the linkage rod 42 to move through the driving mechanism, the plurality of louver blades 2 are further driven to rotate synchronously by the plurality of connecting rods 41 to achieve opening and closing. The driving mechanism adopts a handwheel structure or an electric control actuator in the prior art, or other mechanisms can also be used, as long as it can achieve the driving effect on the linkage rod 42, which will not be elaborated here. When the driving mechanism drives the linkage rod 42 to move up and down, the plurality of louver blades 2 connected thereto can be driven to rotate synchronously to achieve the unfolding or closing operation.

[0030] When the plurality of louver blades 2 are in the closed state, the adjacent two louver blades 2 are in a sealed fit. Specifically, as Figure 6 shown, a mating portion 21 is provided on one side of the louver blade 2, and a sealing portion 22 is provided on the other side. A card slot 211 is provided on the mating portion 21. The card slot 211 extends along the length direction of the louver blade 2 itself. Both ends of the card slot 211 penetrate through the two ends of the louver blade 2. A wool strip 6 is connected in the card slot 211. When the louver blade 2 is in the closed state, the wool strip 6 abuts against the sealing portion 22 of the adjacent louver blade 2 to form a seal. At the same time, two mutually parallel water blocking strips 221 are provided on the sealing portion 22 at intervals. The water blocking strips 221 extend along the length direction of the louver blade 2 itself, and the two water blocking strips 221 are respectively located on both sides of the card slot 211. With this structural design, the water blocking strips 221 and the wool strip 6 are combined with each other, which can effectively prevent water droplets from seeping into the gap between the adjacent two louver blades 2, and the water blocking and sealing effects are remarkable.

[0031] In addition, in order to improve the structural strength, a corrugated section 24 is also provided on the side surface of the louver blade 2 in this embodiment. The corrugated section 24 extends along the length direction of the louver blade 2 itself. The cross section of the corrugated section 24 is a corrugated structure. Compared with a flat plate-like structure, the corrugated structure has better structural strength, better anti-vibration effect and buffering effect.

[0032] The general assembly of a louver for a combined dry and wet closed cooling tower of the utility model realizes the limit of the sealing strip and improves the sealing reliability by arranging a groove 11 on one side of the window frame 1 in contact with the tower body frame; the two ends of the louver blade 2 are rotatably installed on the window frame 1 through a fixing bracket 3, and the installation is simple, convenient and highly firm; through the structural design of the louver blade 2, the sealing effect between two adjacent louver blades 2 is more stable and reliable in the closed state.

[0033] For those skilled in the art, according to the technical solutions and concepts described above, various corresponding changes and deformations can be made, and all such changes and deformations should fall within the protection scope of the claims of the utility model.
