The construction of offshore wind farms needs to transport the components of wind power equipment to the vicinity of offshore foundation by offshore transportation ships, and after the transportation is completed, the installation of wind power equipment is completed at sea. Among them, the wind power blade is one of the core components of the wind power generator. In order to ensure the safety and stability of the wind power blade during transportation, the transportation frame is usually used to fix the wind power blade.

The gear 192 is rotatably connected in the cavity 17. A second rack plate 193 is arranged in mesh with the first rack plate 191 perpendicularly and staggered. The second rack plate 193 is vertically and slidably connected in the cavity 17. An opening 511 is formed in the bearing plate 51. One end of the second rack plate 193 away from the gear 192 passes through the opening 511 and is connected to the surface of the opposite bearing plate 51. Specifically, one end of the second rack plate 193 in the cavity 17 of the fixed seat 14 away from the meshed gear 192 is fixedly connected to the surface of the bearing plate 51 of the moving seat 15. One end of the second rack plate 193 in the cavity 17 of the moving seat 15 away from the meshed gear 192 is fixedly connected to the surface of the bearing plate 51 of the fixed seat 14.

[0052] Referring toFigure 5 and Figure 6 In the initial state, the air bag 52 is in the contracted state. When the tip portion of the wind power blade 3 is placed between the two bearing plates 51, the driving assembly 16 is started and drives the moving seat 15 to gradually approach the fixed seat 14. At this time, the second rack plate 193 on the moving seat 15 gradually moves into the cavity 17 of the fixed seat 14 through the opening 511 of the fixed seat 14. The second rack plate 193 on the fixed seat 14 gradually moves into the cavity 17 of the moving seat 15 through the opening 511. In the process of moving the second rack plate 193, the second rack plate 193 on the moving seat 15 drives the gear 192 in the fixed seat 14 to rotate forward. The second rack plate 193 on the fixed seat 14 drives the gear 192 in the moving seat 15 to rotate forward. The forward rotation of the gear 192 drives the first rack plate 191 arranged horizontally to move the piston rod 182 towards the air pipe. The air bag 52 in the moving seat 15 is gradually filled with gas and continuously expands. When the expanded air bag 52 completely wraps the tip portion of the wind power blade 3, the driving assembly 16 is turned off. During subsequent transportation, the tip portion of the wind power blade 3 is always protected by the expanded air bag 52.

[0053] When it is needed to be unloaded at the destination, the driving assembly 16 drives the moving seat 15 to gradually move away from the fixed seat 14. The second rack plate 193 on the moving seat 15 gradually slides out of the cavity 17 in the fixed seat 14. The second rack plate 193 on the fixed seat 14 also slides out of the cavity 17 in the moving seat 15. In the process of moving the second rack plate 193, the second rack plate 193 on the moving seat 15 drives the gear 192 in the fixed seat 14 to rotate reversely. The second rack plate 193 on the fixed seat 14 drives the gear 192 in the moving seat 15 to rotate reversely. The reverse rotation of the gear 192 drives the first rack plate 191 to move away from the air pipe. The gas in the air bag 52 is gradually extracted. The air bag 52 contracts and becomes smaller. At this time, the wind power blade 3 is more easily unloaded from the second mounting frame 2 without the wrapping of the air bag 52.

[0054] Referring to Figure 5 and Figure 6 The opposite side walls of the second mounting frame 2 are respectively provided with a driving groove 201 and a guide groove 202. The driving assembly 16 includes a screw rod 161 rotatably connected in the driving groove 201 and a guide rod 162 fixedly connected in the guide groove 202. The opposite side walls of the moving seat 15 are both fixedly connected with a connecting plate 163. The connecting plate 163 close to the screw rod 161 is threadedly connected on the screw rod 161 and slidably matched with the driving groove 201. The connecting plate 163 close to the guide rod 162 is slidably connected on the guide rod 162 and slidably matched with the guide groove 202. A second motor 164 is fixedly installed on the second mounting frame 2. The output shaft of the second motor 164 is fixedly connected with the screw rod 161.

[0055] When the loading device places the tip portion of the wind power blade 3 between the two bearing plates 51, the second motor 164 drives the screw rod 161 to rotate forward, the rotation of the screw rod 161 drives the connecting plate 163 to move downward in the driving groove 201, the connecting plate 163 drives the moving seat 15 to gradually approach the fixed seat 14, when the air bags 52 in the moving seat 15 and the fixed seat 14 are inflated and abut against the wind power blade 3, the second motor 164 is turned off, when transported to the designated place, the second motor 164 drives the screw rod 161 to rotate reversely, the rotation of the screw rod 161 drives the moving seat 15 to gradually move away from the fixed seat 14, in the process that the moving seat 15 moves away from the fixed seat 14, the air bags 52 gradually shrink and adhere to the surface of the bearing plate 51, which facilitates the unloading device to unload the wind power blade 3.

[0056] The implementation principle of the offshore wind power blade transportation device in the embodiment of the application is as follows: when the wind power blade 3 needs to be transported offshore, the loading device hoists the wind power blade 3 onto the first mounting frame 1 and the second mounting frame 2, then the inner fixing assembly 42 and the outer fixing assembly 41 clamp the connecting end of the wind power blade 3 from inside and outside, then the worker starts the driving assembly 16, in the process that the driving assembly 16 drives the moving seat 15 to approach the fixed seat 14, the transmission assembly 19 drives the air charging assembly 18 to inflate the air bag 52, the air bag 52 is inflated by the gas and then expands and wraps around the outer periphery of the tip portion of the wind power blade 3, when external force is encountered during transportation, the air bag 52 full of gas can absorb and buffer the vibration energy generated by the tip portion, offset the work done by the external force on the tip portion of the wind power blade 3, so as to reduce the internal stress generated by the tip portion, and further reduce the possibility that the tip portion vibrates greatly and causes damage to the blade, finally the transportation quality of the wind power blade 3 is improved.

[0057] The above are the preferred embodiments of the application, which do not limit the protection scope of the application, therefore: any equivalent changes made on the structure, shape and principle of the application should be covered within the protection scope of the application.
