[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives the rotor to rotate and ultimately outputs alternating current. When transporting wind turbine blades, a transport device is usually required.

[0003] A search revealed that the announcement number is CN202703386U, and the name is "Wind Turbine Generator Blade Transport Device and Transport Vehicle," which includes a floor plate installed on a trailer. Research and analysis revealed that although it has the advantages of convenient obstacle avoidance during vehicle movement, easy operation, and accuracy and reliability, it also has the following disadvantages to a certain extent.

[0004] For example, during the use of this device, it is fixed on the vehicle for transportation. When unloading the wind turbine blades being transported, a large lifting device is required. The blades cannot be directly removed close to the ground, which increases the workload of the staff and is inconvenient for people to use. In order to solve the above technical problems, we have designed a wind turbine blade transportation device. Utility Model Content

[0021] Please see Figures 1-4 A wind turbine blade transport device includes a transport vehicle 1. A traction head 2 is bolted to the front of the transport vehicle 1. An installation groove 3 is provided on the top of the transport vehicle 1. A first hydraulic rod 4 is bolted to the inner cavity of the installation groove 3. A connecting plate 5 is bolted to the top of the first hydraulic rod 4. A movable shell 6 is welded to the opposite side of the connecting plate 5. An anti-vibration component 21 is provided at the bottom of the inner cavity of the movable shell 6. A cargo shell 15 is slidably connected to the inner cavity of the movable shell 6. A positioning airbag 17 is bolted to the inner cavity of the cargo shell 15. A vertical plate 18 is welded to the front of the top of the transport vehicle 1. A suction pump 19 is bolted to the front of the vertical plate 18. A solenoid valve 20 is connected to the top of the suction pump 19.

[0022] Please see Figure 1 and Figure 4 The seismic component 21 includes a damper 13. The bottom of the damper 13 is connected to the movable shell 6 by bolts, and the top of the damper 13 is connected to the load shell 15 by bolts. A buffer spring 14 is welded to the bottom of the load shell 15. By setting the damper 13 and the buffer spring 14, the damper can play a role in buffering and shock absorption, and can effectively prevent the blades inside the load shell 15 from being damaged by vibration. The bottom of the buffer spring 14 is welded to the movable shell 6. Limiting holes 12 are opened on both sides of the movable shell 6.

[0023] Please see Figure 1 and Figure 4 Guide blocks 16 are welded to both sides of the cargo shell 15. The surface of the guide block 16 is slidably connected to the limiting hole 12. By setting the guide block 16 and the limiting hole 12, the guide can play a guiding role and effectively prevent the cargo shell 15 from shaking violently.

[0024] Please see Figure 1 and Figure 3 The movable shell 6 has slots 7 on both sides, and support blocks 8 are welded to both sides of the top of the transport vehicle 1. The top of the support block 8 is connected to the second hydraulic rod 9 by bolts. The opposite side of the second hydraulic rod 9 is connected to the drive plate 10 by bolts. The opposite side of the drive plate 10 is welded to the locking block 11. The surface of the locking block 11 is slidably connected to the slot 7. By setting the slot 7, support block 8, second hydraulic rod 9, drive plate 10 and locking block 11, the movable shell 6 can be easily limited, and the pressure on the first hydraulic rod 4 can be reduced.

[0025] Please see Figure 1 and Figure 2 The top of the solenoid valve 20 is connected to a telescopic tube via a pipe. By setting the telescopic tube, it is possible to provide a space for the cargo shell 15 to move. The rear side of the telescopic tube is connected to the positioning airbag 17 via a pipe.

[0026] Please see Figure 1 and Figure 3 A baffle is welded to the front side of the movable shell 6. By setting the baffle, it is easy to position the movable shell 6 and to restore the movable shell 6 to its original position. The top of the baffle is in contact with the transport vehicle 1.

[0027] Please see Figure 1 The bottom of the suction pump 19 is threaded with a filter cover, which can filter and effectively prevent debris from being sucked into the suction pump 19. The positioning airbag 17 is provided with an anti-slip pad on the opposite side, which can facilitate the positioning of the blades and effectively prevent the blades from moving too much.

[0028] The positioning airbag 17 is made of PA66, with a tensile strength of 4-9 cN / dtex, which can withstand instantaneous impact tension and has a breaking elongation of 20-40%. It can be violently stretched during inflation without breaking, and its mechanical properties decay slowly after repeated inflation and deflation.

[0029] The suction pump 19 is model GWJ550W. It operates on the principle of a piston compressor and is an oil-free air compressor with low noise performance.

[0030] In use, the device is controlled by an external controller. The transport vehicle 1 is connected to the tractor via the traction head 2. The blades to be transported are placed inside the carrying shell 15. Then, the solenoid valve 20 is opened to connect the suction pump 19 to the positioning airbag 17. The suction pump 19 then inflates the positioning airbag 17, causing it to fit snugly against the blades inside the carrying shell 15, preventing excessive shaking during transport. After inflation, the solenoid valve 20 is closed to seal the pipeline, allowing the blades to be transported. During transport, the damper 13 provides damping, and the buffer spring 14 provides cushioning, effectively preventing movement. To prevent excessive vibration in the cargo shell 15 and effectively prevent damage to the blades inside the cargo shell 15, after transportation to the destination, the second hydraulic rod 9 extends and retracts, causing the driving plate 10 and the locking block 11 to move laterally, pulling the locking block 11 out of the locking slot 7. Then, the first hydraulic rod 4 extends and retracts, causing the connecting plate 5, the movable shell 6, the damper 13, the buffer spring 14, the cargo shell 15, the positioning airbag 17, and the blades to move up and down, bringing the blades close to the ground. Then, the solenoid valve 20 connects the positioning airbag 17 to the suction pump 19, and the gas in the positioning airbag 17 is extracted and discharged by the suction pump 19. Then, the blades can be unloaded directly by a ground tractor without the need for a large lifting device.

[0031] In summary, this wind turbine blade transport device, through its positioning airbag 17, vertical plate 18, suction pump 19, solenoid valve 20, and anti-vibration component 21, solves the problem that during use, the device is fixed on a vehicle for transport, requiring a large lifting device to unload the transported wind turbine blades, making it impossible to remove the blades directly from the ground, increasing the workload of workers, and making it inconvenient for people to use.
