On the other hand, it is convenient for drivers who transport the wind turbine nacelle cover to know that looseness occurs between the wind turbine nacelle cover and the movable support frame, so as to fix the loosened wind turbine nacelle cover and the movable support frame in time.

[0022] 3. The present invention has the functions of preventing rain, snow and hail, and plays a protective role on the wind turbine cabin cover during transportation; the wind below the multifunctional movable frame can move upward through two circles of arc-shaped guide grooves, and the wind above the multifunctional movable frame can move downward through two circles of arc-shaped guide grooves, thereby reducing the resistance between the multifunctional movable frame and the air; the water in the two circular water collection boxes can be discharged through four circular drainage pipes, thereby preventing rain, snow, hail and the like from contacting the wind turbine cabin cover while ensuring the reduction of resistance;

[0023] In addition, when the transport vehicle reaches the transport destination, the staff connects the four U-shaped lifting ears to the crane hooks through ropes, and then uses the crane to place the multifunctional movable frame on the ground nearby, and then places the wind turbine cabin cover on the top of the rubber protective pad C, which plays a temporary supporting role for the wind turbine cabin cover after transportation, preventing the ground from scratching the bottom of the wind turbine cabin cover.

On the other hand, it is convenient for the driver who transports the wind turbine nacelle cover to know that the wind turbine nacelle cover and the movable support frame 103 are loose, so as to facilitate the loosened wind turbine nacelle cover to be connected with the movable support frame 103. The movable support frame 103 is fixed in time; the setting of the multifunctional movable frame 401 plays the role of preventing rain, snow, hail, etc., and plays a protective role for the wind turbine cabin cover during transportation; the wind below the multifunctional movable frame 401 can move upward through the two circles of arc-shaped guide grooves 4031, and the wind above the multifunctional movable frame 401 can move downward through the two circles of arc-shaped guide grooves 4031, reducing the resistance between the multifunctional movable frame 401 and the air; the water in the two circular water collection boxes 403 can be discharged through the four circular drainage pipes 404, and under the premise of ensuring the reduction of resistance, rain, snow, hail, etc. are prevented from contacting the wind turbine cabin cover;

[0057] When the transport vehicle reaches the transport end, the four limit knobs 406 are turned to separate the four limit knobs 406 from the four circular mounting rods 302, and the staff then connects the four U-shaped lifting ears 407 to the crane hooks through ropes, and then places the multifunctional movable frame 401 on the ground nearby through the crane. The staff then presses the six limit blocks 210 inwards, and then pulls the six steel ropes 201 upwards to make the six limit blocks 210 pass through the movable support frame 103; the wind turbine cabin cover is placed on the top of the rubber protective pad C405 by the crane, which plays a temporary supporting role for the wind turbine cabin cover after transportation and prevents the ground from scratching the bottom of the wind turbine cabin cover. The last transport vehicle takes away all the previous multifunctional mechanisms B400 for easy use during the next transportation.
