The utility model discloses a cooling tower fan capable of preventing the fan from rotating reversely, which relates to the technical field of cooling tower fans and comprises a fan unit, and the fan unit comprises a fan motor, a coupler, a transmission shaft, a speed reducing mechanism, a fan impeller, a one-way bearing and a bearing seat. The output end of the fan motor is connected with the coupler, the coupler is detachably arranged and connected with the transmission shaft, the transmission shaft transversely penetrates through the one-way bearing and then is connected with the input end of the speed reducing mechanism, the one-way bearing is installed on the bearing seat, and the output end of the speed reducing mechanism is connected with the fan impeller. And the transmission shaft can only rotate in one direction in the one-way bearing, namely can only rotate in one direction, namely can only rotate in the forward rotation direction of the fan, so that the fan is prevented from rotating reversely.
