DETAILED DESCRIPTION

[0017] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0018] Reference Figure 2 As shown, an embodiment of the present application discloses an air distribution device for a cooling tower, comprising: a plurality of air distribution plates 2, one end of which is arranged in an air inlet 15, and the other end extends toward the central axis of the cooling tower; wherein, from top to bottom along the vertical direction, the length of the air distribution plates 2 increases successively, thereby forming air distribution channels of different lengths under different air distribution plates 2.

[0019] In the present invention, a plurality of air distribution plates 2 are provided, and the lengths of the air distribution plates 2 are increased successively from top to bottom in the vertical direction, so as to form air distribution channels of different lengths under different air distribution plates 2; under the action of the induced draft fan 11, the external fresh air entering the cooling tower from the air inlet 15 can flow toward the central axis along the air distribution channels of different lengths under the guidance of the air distribution plates 2; by using the present invention, the path of the external fresh air flowing from the side wall to the central axis can be extended, and in the projection in the vertical direction, the coverage area of ​​the external fresh air in the cooling tower can be effectively improved, thereby improving the cooling efficiency of the high-temperature water in the cooling tower.

[0020] Reference Figure 3 As shown, the device also includes: a mounting shaft 41, which is arranged on the cooling tower and is located in the air inlet 15, and the air distribution plate 2 is rotatably arranged on the mounting shaft 41; a bearing rod 42, which is horizontally arranged below the air distribution plate 2 and is used to resist the air distribution plate 2; a telescopic component 5, the piston rod of the telescopic component 5 is connected to the bearing rod 42, and the piston rod of the telescopic component 5 performs a telescopic movement, which can change the distance between the bearing rod 42 and the mounting shaft 41, thereby guiding the air distribution plate 2 to rotate around the mounting shaft 41.

[0021] During specific use, the piston shaft of the telescopic component 5 makes an extension movement, which can drive the load-bearing rod 42 to move in the horizontal direction away from the installation axis 41, thereby pushing the air distribution plate 2 to rotate upward around the installation axis 41; the piston shaft of the telescopic component 5 makes a contraction movement, which can drive the load-bearing rod 42 to move in the horizontal direction toward the installation axis 41, and under the action of the air distribution plate 2's own gravity, the air distribution plate 2 is driven to rotate downward around the installation axis 41.

[0022] In the present invention, the piston rod of the telescopic component 5 makes telescopic movement, which can guide the air distribution plate 2 to rotate around the installation axis 41, so as to change the distance between the air distribution channel and the central axis, which can further increase the coverage area of ​​the external fresh air.

[0023] Specifically, the device also includes: a mounting plate 61 vertically arranged on the piston rod of the telescopic component 5; a connecting rod 62, one end of which is connected to the mounting plate 61 and the other end is connected to the bearing rod 42; and a plurality of ventilation holes 63 are opened on the mounting plate 61.

[0024] It is understandable that the telescopic component 5 can be a hydraulic cylinder, which drives the piston rod to perform telescopic movement, thereby driving the installation plate 61 to move, and thus driving the multiple air distribution plates 2 to move.

[0025] Specifically, the air distribution plate 2 is made of stainless steel to prevent the air distribution plate 2 from rusting and reduce the mass of the liquid in the cooling tower; in addition, the device also includes: a counterweight block 7. Of course, the counterweight block 7 can be made of stainless steel with a density greater than that of the air distribution plate 2, and is arranged on the side of the air distribution plate 2 away from the installation axis 41, so as to increase the gravity of the air distribution plate 2 away from the installation axis 41, and ensure that the air distribution plate 2 can be driven to rotate downward around the installation axis 41 under the action of the gravity of the counterweight block 7.

[0026] Furthermore, the device also includes a protective cover 3, which is arranged on the outer wall of the cooling tower and is L-shaped, with one end connected to the air inlet 15 and the other end extending upward in the vertical direction for a fixed length to prevent the liquid in the cooling tower from splashing out of the cooling tower.

[0027] The telescopic component 5 is installed on a side of the protective cover 3 away from the cooling tower.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention. Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention.
