[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention plays a protective role in the bottom of the wind turbine nacelle cover, avoiding scratches on the bottom of the wind turbine nacelle cover, and improving the transportation safety and stability of the wind turbine nacelle cover; when the wind turbine nacelle cover is installed on the top of the movable support frame, six helical springs A are compressed to a certain extent under the gravity of the wind turbine nacelle cover. When the transport vehicle travels on an uneven road surface, the wind turbine nacelle cover has an upward and downward movement effect, playing a buffering role and providing buffering protection for the wind turbine nacelle cover during transportation.

[0020] 2. The setting of six steel wire ropes and three rubber protection pads B in the present invention plays an auxiliary limiting role in the wind turbine nacelle cover during transportation. Even when the wind turbine nacelle cover becomes loose from the movable support frame, the six steel wire ropes and three rubber protection pads B can still play a secondary limiting role for the wind turbine nacelle cover, ensuring the stability during transportation; when the three connecting blocks need to be connected to the movable support frame, the staff inserts the three connecting blocks into the movable support frame and then presses the three connecting blocks forcefully to make the six limiting blocks pass through the movable support frame; when the three connecting blocks need to be separated from the movable support frame, the staff presses the six limiting blocks inward and then pulls up the six steel wire ropes to make the six limiting blocks pass through the movable support frame, facilitating the installation and disassembly of the three connecting blocks;

[0021] In addition, when the wind turbine nacelle cover becomes loose from the movable support frame, the wind turbine nacelle cover can pull the steel wire rope at the corresponding position to move. When the wind turbine nacelle cover pulls the steel wire rope at the corresponding position to move, the limiting block at the corresponding position can contact the movable support frame; when the top of the limiting block at the corresponding position contacts the movable support frame, the switch at the corresponding position is in a pressed and energized state, and the sound and light alarm at the corresponding position is in a working state. On the one hand, it plays a warning role for nearby vehicles, facilitating nearby vehicles to maintain a safe distance. On the other hand, it is convenient for the driver transporting the wind turbine nacelle cover to know that the wind turbine nacelle cover has become loose from the movable support frame, facilitating timely fixing of the loosened wind turbine nacelle cover and the movable support frame.

[0022] 3. The present invention plays roles such as rain prevention, snow prevention, and hail prevention, and plays a protective role for the wind turbine nacelle cover during transportation; the wind below the multifunctional movable frame can move upward through two circles of arc-shaped guiding grooves, and the wind above the multifunctional movable frame can move downward through two circles of arc-shaped guiding grooves, reducing the resistance between the multifunctional movable frame and the air; the water in the two circular water collecting boxes can be discharged through four circular drain pipes, avoiding the contact of rain, snow, hail, etc. with the wind turbine nacelle 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 lugs to the crane hook through ropes. Then, the multi-functional movable frame is placed on the nearby ground by the crane. After that, the wind turbine nacelle cover is placed on the top of the rubber protection pad C, which plays a temporary supporting role for the transported wind turbine nacelle cover and prevents the ground from scratching the bottom of the wind turbine nacelle cover. Finally, one transport vehicle can take away all the previous multi-functional mechanism B; the setting of the four auxiliary support plates and the two circular water collecting boxes increases the contact area with the ground and improves the supporting strength of the multi-functional movable frame.

When the transport vehicle travels on an uneven road surface, the wind turbine nacelle cover has an upward and downward movement effect, playing a buffering role and providing buffer protection for the wind turbine nacelle cover during transportation.

[0048] In the embodiments of the present disclosure, such as Figure 4 , Figure 6 and Figure 8As shown in the figure, the multi-functional mechanism A200 includes: a steel wire rope 201, a limit block 202, a rubber protection pad B203, and a storage battery 204; there are two steel wire ropes 201 in total, and the left ends of the two steel wire ropes 201 are slidably installed on the movable support frame 103; the limit block 202 is fixedly installed at the left ends of the two steel wire ropes 201; the rubber protection pad B203 is fixedly installed outside the two steel wire ropes 201; the storage battery 204 is fixedly installed on the top of the rubber protection pad B203; the multi-functional mechanism A200 further includes: a sound and light alarm 205, a switch 206, a limit clamping plate 207, and a helical spring B208; the sound and light alarm 205 is fixedly installed on the top of the rubber protection pad B203, and the storage battery 204 is electrically connected to the sound and light alarm 205; the switch 206 is fixedly installed on the limit block 202, and the switch 206 is electrically connected to the storage battery 204 and the sound and light alarm 205; when the top of the limit block 202 contacts the movable support frame 103, the switch 206 is in a pressed and powered-on state, and the sound and light alarm 205 is in a working state; the limit clamping plate 207 is fixedly installed at the left ends of the two steel wire ropes 201, and the bottom of the limit clamping plate 207 contacts the movable support frame 103; there are two helical springs B208 in total, and the two helical springs B208 are sleeved outside the two steel wire ropes 201, and the two helical springs B208 are located between the movable support frame 103 and the limit block 202; the multi-functional mechanism A200 further includes: a connecting plug 209, a limit clamping block 210, and a helical spring C211; the connecting plug 209 is fixedly installed at the right ends of the two steel wire ropes 201, and the connecting plug 209 is also slidably connected to the movable support frame 103, and a chamfer is provided at the bottom of the connecting plug 209; there are two limit clamping blocks 210 in total, and the two limit clamping blocks 210 are slidably installed inside the connecting plug 209; the tops of the two limit clamping blocks 210 contact the movable support frame 103, and chamfers are provided at the tops of the two limit clamping blocks 210; the helical spring C211 is installed between the two limit clamping blocks 210;

[0049] Its specific functions are as follows: The six steel wire ropes 201 and the three rubber protection pads B203 play an auxiliary limiting role for the wind turbine nacelle cover during transportation. Even when the wind turbine nacelle cover becomes loose from the movable support frame 103, the six steel wire ropes 201 and the three rubber protection pads B203 can also play a secondary limiting role for the wind turbine nacelle cover, ensuring the stability during transportation. Also, since the six limit blocks 210 are slidably installed inside the three connecting inserts 209, and the three spiral springs C211 are installed between the six limit blocks 210. When the three connecting inserts 209 need to be connected to the movable support frame 103, the staff inserts the three connecting inserts 209 onto the movable support frame 103, and then presses the three connecting inserts 209 forcefully to make the six limit blocks 210 pass through the movable support frame 103.

[0050] In addition, since the left ends of the two steel wire ropes 201 are slidably installed on the movable support frame 103, and the two spiral springs B208 are sleeved outside the two steel wire ropes 201, and the two spiral springs B208 are located between the movable support frame 103 and the limit block 202. When the wind turbine nacelle cover becomes loose from the movable support frame 103, the wind turbine nacelle cover can pull the corresponding steel wire rope 201 to move. When the wind turbine nacelle cover pulls the corresponding steel wire rope 201 to move, the corresponding limit block 202 can contact the movable support frame 103. Also, since the three storage batteries 204 are electrically connected to the three sound and light alarms 205, and the three switches 206 are electrically connected to the three storage batteries 204 and the three sound and light alarms 205. When the top of the corresponding limit block 202 contacts the movable support frame 103, the corresponding switch 206 is in a pressed and energized state, and the corresponding sound and light alarm 205 is in a working state. On the one hand, it plays a warning role for the nearby vehicles, facilitating the nearby vehicles to maintain a safe distance. On the other hand, it is convenient for the driver transporting the wind turbine nacelle cover to know that the wind turbine nacelle cover has become loose from the movable support frame 103, facilitating the timely fixation of the loosened wind turbine nacelle cover and the movable support frame 103.

[0051] In the embodiment of the present disclosure, as Figures 9 to 12As shown, the installation mechanism 300 includes: a rectangular installation block 301, a circular installation rod 302, and a support disc 303.

[0052] The multi-functional mechanism B400 includes: a multi-functional movable frame 401 and an auxiliary support plate 402. The multi-functional movable frame 401 is slidably installed on the outsides of the four circular installation rods 302. There are four auxiliary support plates 402 in total, and the four auxiliary support plates 402 are fixedly installed at the bottom corners of the multi-functional movable frame 401. The four auxiliary support plates 402 are slidably connected to the four circular installation rods 302, and the bottoms of the four auxiliary support plates 402 are in contact with the four support discs 303. The multi-functional mechanism B400 further includes: a circular water collection box 403 and a circular drain pipe 404. There are two circular water collection boxes 403 in total, and the two circular water collection boxes 403 are fixedly installed at the bottom of the multi-functional movable frame 401. An arc-shaped guiding groove 4031 is provided in a circle on the outer walls of the two circular water collection boxes 403, and the bottoms of the two circular water collection boxes 403 are flush with the bottoms of the four auxiliary support plates 402. There are four circular drain pipes 404 in total, and the four circular drain pipes 404 are fixedly installed on the front and back sides of the two circular water collection boxes 403, and the four circular drain pipes 404 penetrate through the multi-functional movable frame 401. The multi-functional mechanism B400 further includes: a rubber protection pad C405, a limit knob 406, and a U-shaped lifting lug 407. The rubber protection pad C405 is fixedly installed on the top of the multi-functional movable frame 401. There are four limit knobs 406 in total, and the four limit knobs 406 are slidably installed on the multi-functional movable frame 401, and the four limit knobs 406 are also threadedly connected to the four circular installation rods 302. There are four U-shaped lifting lugs 407 in total, and the four U-shaped lifting lugs 407 are fixedly installed on the top of the multi-functional movable frame 401.

[0053] Its specific functions are as follows: Since the multifunctional movable frame 401 is slidably installed outside the four circular mounting rods 302, it plays a role in preventing rain, snow, hail, etc., and protects the wind turbine nacelle cover during transportation. Also, because the two circular water collecting boxes 403 are fixedly installed at the bottom of the multifunctional movable frame 401, and a circle of arc-shaped guiding grooves 4031 are respectively formed on the outer walls of the two circular water collecting boxes 403, the wind below the multifunctional movable frame 401 can move upward through the two circles of arc-shaped guiding grooves 4031, and the wind above the multifunctional movable frame 401 can move downward through the two circles of arc-shaped guiding grooves 4031, reducing the resistance between the multifunctional movable frame 401 and the air; the water in the two circular water collecting boxes 403 can be discharged through the four circular drain pipes 404, avoiding the contact of rain, snow, hail, etc. with the wind turbine nacelle cover while ensuring the reduction of resistance.

[0054] In addition, since the four U-shaped lifting lugs 407 are fixedly installed at the top of the multifunctional movable frame 401, when the transport vehicle reaches the transport destination, the staff connects the four U-shaped lifting lugs 407 to the crane hook through a rope, and then places the multifunctional movable frame 401 on the nearby ground through the crane. Then, the wind turbine nacelle cover is placed on the top of the rubber protection pad C405, which plays a temporary supporting role for the transported wind turbine nacelle cover, avoiding the ground from scratching the bottom of the wind turbine nacelle cover. Finally, one transport vehicle can take away all the previous multifunctional mechanism B400; also, because the four auxiliary support plates 402 are fixedly installed at the bottom corners of the multifunctional movable frame 401, and the bottoms of the two circular water collecting boxes 403 are flush with the bottoms of the four auxiliary support plates 402, and the bottom of the multifunctional movable frame 401 is flush with the four auxiliary support plates 402 and the two circular water collecting boxes 403, the contact area with the ground is increased, and the support strength of the multifunctional movable frame 401 is improved.

[0055] The specific usage method and functions of this embodiment:

[0056] When the present invention is in use, the support base 101 is welded to a large flat trailer, and then the wind turbine nacelle to be transported is placed on the top of the movable support frame 103. After that, the wind turbine nacelle is connected to the movable support frame 103 by bolts. Then, three connecting plugs 209 are inserted into the movable support frame 103, and the three connecting plugs 209 are pressed forcefully so that six limiting blocks 210 pass through the movable support frame 103. When the wind turbine nacelle is installed on the top of the movable support frame 103, six spiral springs A106 are compressed to a certain extent under the gravity of the wind turbine nacelle. When the transport vehicle travels on an uneven road surface, the wind turbine nacelle has the effect of moving up and down, playing a buffering role and protecting the wind turbine nacelle during transportation. The setting of six steel wire ropes 201 and three rubber protection pads B203 plays an auxiliary limiting role for the wind turbine nacelle during transportation. Even when the wind turbine nacelle and the movable support frame 103 become loose, the six steel wire ropes 201 and the three rubber protection pads B203 can also play a secondary limiting role for the wind turbine nacelle, ensuring the stability during transportation. When the wind turbine nacelle and the movable support frame 103 become loose, the wind turbine nacelle can pull the steel wire rope 201 at the corresponding position to move. When the wind turbine nacelle pulls the steel wire rope 201 at the corresponding position to move, the limiting block 202 at the corresponding position can contact the movable support frame 103. When the top of the limiting block 202 at the corresponding position contacts the movable support frame 103, the switch 206 at the corresponding position is in a pressed and powered-on state, and the sound and light alarm 205 at the corresponding position is in a working state. On the one hand, it plays a warning role for nearby vehicles, facilitating the nearby vehicles to keep a safe distance. On the other hand, it is convenient for the driver transporting the wind turbine nacelle to know that the wind turbine nacelle and the movable support frame 103 have become loose, facilitating the timely fixing of the loosened wind turbine nacelle and the movable support frame 103. The setting of the multifunctional movable frame 401 plays roles such as rain protection, snow protection, and hail protection, protecting the wind turbine nacelle during transportation. The wind below the multifunctional movable frame 401 can move upward through two circles of arc-shaped guiding grooves 4031, and the wind above the multifunctional movable frame 401 can move downward through two circles of arc-shaped guiding grooves 4031, reducing the resistance between the multifunctional movable frame 401 and the air. The water in the two circular water collecting boxes 403 can be discharged through four circular drain pipes 404, avoiding the contact of rain, snow, hail, etc. with the wind turbine nacelle while ensuring the reduction of resistance.

[0057] When the transport vehicle reaches the transport destination, rotate the four limit knobs 406 so that the four limit knobs 406 are separated from the four circular mounting rods 302. Then, the staff connects the four U-shaped lifting lugs 407 to the crane hook through a rope. After that, the multi-functional movable frame 401 is placed on the nearby ground by the crane. Then, the staff presses six limit blocks 210 inward and then pulls six steel wires 201 upward so that the six limit blocks 210 pass through the movable support frame 103. The wind turbine nacelle is placed on the top of the rubber protection pad C405 by the crane, which plays a temporary supporting role for the transported wind turbine nacelle and avoids scratching the bottom of the wind turbine nacelle on the ground. Finally, the last transport vehicle takes away all the previous multi-functional mechanisms B400 for use in the next transport.
