Since the rubber pad 54 is supported by the spring 56, it will not affect the rise of the arc block 53. Then the pull rope 55 is pulled to make the rubber pad 54 cover the top of the motor 2, thereby protecting the output end of the motor 2 and avoiding damage caused by collision and vibration during transportation, thereby improving the installation performance of transportation. At the same time, this structure is also convenient for disassembly and installation, and does not affect the normal use of the fan.

[0027] The output end of the motor 2 is fixedly mounted with a mounting block 21, a mounting groove 31 is provided at the bottom of the disc 3, a latch 22 is provided at the bottom of the mounting block 21, the mounting block 21 is engaged with the inside of the mounting groove 31, the disc 3 is connected to the output end of the motor 2 through the mounting groove 31 and the mounting block 21, and is locked by the latch 22, so that the disc 3 is easy to install and disassemble with the motor 2, thereby making the whole easy to transport.

[0028] A positioning hole 32 is provided on the outer surface of the disk 3, a connecting block 41 is provided at one end of the fan blade 4, a connecting pin 42 is provided on one side of the connecting block 41, and the connecting pin 42 is connected to the inside of the positioning hole 32, so that the fan blade 4 can be removed from the outer surface of the disk 3 for easy transportation.

[0029] A slide groove 11 is provided at the bottom of the base 1, and a mounting frame 6 is slidably connected to the inner wall of the slide groove 11. The whole is installed inside the cooling tower through the mounting frame 6, and the pull-out length of the mounting frame 6 can be adjusted according to the size of the cooling tower, and then fixed by bolts, making the installation more flexible. At the same time, the mounting frame 6 can be pushed back into the slide groove 11 during transportation to reduce the space occupied by transportation.

[0030] A support frame 7 is welded to the bottom of the base 1, and the mounting frame 6 is located inside the support frame 7 to provide stable support.

[0031] A hoisting block 8 is provided on the upper surface of the base 1 to facilitate hoisting the base 1 and the motor 2 together into a transport vehicle.

[0032] A control panel 9 is disposed on the outer surface of the base 1 , and the control panel 9 is connected to the motor 2 signal. When the installation is completed, the motor 2 can be driven to rotate through the buttons on the control panel 9 to make the fan run normally.

[0033] Specifically, since the output end of the motor 2 is fixedly mounted with a mounting block 21, a mounting groove 31 is provided at the bottom of the disc 3, a latch 22 is provided at the bottom of the mounting block 21, and the mounting block 21 is engaged with the inside of the mounting groove 31, the disc 3 is connected to the output end of the motor 2 through the mounting groove 31 and the mounting block 21, and is locked by the latch 22, so that the disc 3 is easy to install and remove from the motor 2, and a positioning hole 32 is provided on the outer surface of the disc 3, a connecting block 41 is provided at one end of the fan blade 4, and a connecting pin 42 is provided on one side of the connecting block 41, and the connecting pin 42 is connected to the inside of the positioning hole 32, so that the fan blade 4 can be removed from the outer surface of the disc 3. When the disc 3 and the fan blade 4 at the output end of the motor 2 are removed, and because the upper surface of the base 1 is provided with a lifting block 8, it is necessary to lift the base 1 and the motor 2 into the transportation tool through the lifting block 8. Therefore, after the arc block 53, the rubber pad 54, the pull rope 55 and the spring 56 are assembled and connected to the annular disk 52 by bolts, the arc block 53 is located around the output end of the motor 2 by extending the electric push rod 51. Since the rubber pad 54 is elastically supported, the arc block 53 is located around the output end of the motor 2. The spring 56 supports the rise of the arc block 53, and then the pull rope 55 is pulled to make the rubber pad 54 cover the top of the motor 2.
