The surface of the fixing bolt 409d is connected to the inner wall of the threaded hole 409e and the threaded groove 409f by threads on one side of the surface of the fixing bolt 409d.

[0035] In this embodiment, by setting a positioning block 409a, a snap-fit ​​block 409b, a snap-fit ​​groove 409c, a fixing bolt 409d, a threaded hole 409e, and a threaded groove 409f, the guide plate body 3 is installed by inserting the snap-fit ​​block 409b into the snap-fit ​​groove 409c of the positioning block 409a. Then, by rotating the fixing bolt 409d, the fixing bolt 409d will move downward under the action of the threaded hole 409e, so that the fixing bolt 409d moves into the threaded groove 409f of the snap-fit ​​block 409b, thereby fixing the snap-fit ​​block 409b and completing the installation of the guide plate body 3. The operation is relatively convenient.

[0039] Working principle: In use, the guide plate 3 is installed by inserting the snap-fit ​​block 409b into the snap-fit ​​groove 409c of the positioning block 409a. Then, the fixing bolt 409d is rotated, and the fixing bolt 409d moves downward under the action of the threaded hole 409e, so that the fixing bolt 409d moves into the threaded groove 409f of the snap-fit ​​block 409b, thus fixing the snap-fit ​​block 409b and completing the installation of the guide plate 3. The operation is relatively convenient. The guide plate 3 can be disassembled by reversing the operation, which facilitates the disassembly, maintenance or replacement of the guide plate 3 in the future. When the cooling tower body 1 is working, air is introduced through the air inlet 2 for cooling. The guide plate 3 can guide the airflow. During use, the stepper motor 403 can be started according to the heat exchange requirements, so that the output shaft of the stepper motor 403 drives the transmission gear 404 to rotate. The transmission gear 404 drives the driven gear 405 to rotate via the transmission belt 406. The driven gear 405 drives the first rotating rod 407 to rotate within the inner cavity of the first fixed frame 401 via a bearing. The first rotating rod 407 drives the guide plate body 3 to rotate via the positioning block 409a and the locking block 409b. At this time, the second rotating rod 408 follows the guide plate body 3 to rotate within the inner cavity of the second fixed frame 402 via a bearing, thereby adjusting the angle of the guide plate body 3 and thus adjusting the airflow direction, improving the flexibility of use. Then, by pulling the moving handle 504, the moving handle 504 drives the sliding sleeve 501 to slide on the surface of the guide plate body 3. The guide plate body 3 drives the L-shaped fixed plate 502 and the cleaning brush 503 to move, thereby facilitating the cleaning of dust that has adhered to the guide plate body 3 due to long-term use, bringing convenience to the user's maintenance work.

[0040] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
