For those skilled in the art, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0043] With the rise of the new energy industry, new energy power generation technologies emerge in an endless stream, and wind power generation is an important part of new energy power generation. Wind power generation equipment includes onshore wind turbines. Usually, onshore wind turbines are installed in remote areas with sparse populations such as plateaus, mountains, and deserts, which are far away from the manufacturing sites of onshore generator components. Therefore, the long-distance transportation of wind turbine blades has become an urgent problem to be solved.

[0044] Existing onshore wind turbines include wind turbine blades and a generator body. The wind turbine blades are mounted on the generator body and are configured so that wind energy drives the wind turbine blades to rotate and drive the generator body to generate electricity. Since wind turbine blades are large in size, they are usually transported by special transport vehicles. However, the transportation route is long and rugged, and there are many risks of bumping into the wind turbine blades when transported by special transport vehicles. In addition, wind turbine blades are long and there are difficulties in traffic control. Therefore, air transportation is usually preferred as a transportation method for wind turbine blades.

[0045] However, due to the huge length and width of the fan blades, the wind-receiving area of ​​the fan blades is large. During air transportation, the airflow blows to the sides of the fan blades, causing the fan blades to experience greater resistance, that is, they are greatly affected by the side wind, resulting in high transportation energy consumption and low transportation efficiency.

[0046] In view of the above problems, the present application provides a wind turbine blade transportation device to solve the problem that the existing blades are easily affected by crosswinds during air transportation, resulting in high transportation energy consumption and low transportation efficiency.

[0047] The present application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] Reference Figure 1 and Figure 2 As shown, an embodiment of the present application provides a wind turbine blade transportation device, which includes an aircraft 100 , a detection device 200 and a rotation adjustment assembly 300 .

[0049] The aircraft 100 has a control cabin 110, which is disposed at the front and lower part of the aircraft 100. Specifically, the control cabin 110 is a trapezoidal body, and its bottom is made of fully transparent glass material for easy observation.

[0050] The detection device 200 is arranged on the aircraft 100, and is used to detect wind direction and wind speed. The detection device 200 is communicatively connected with the control cabin 110; the rotation adjustment assembly 300 includes a rotation support 310, which is rotationally connected to the aircraft 100 and is used to fix the fan blades 1000.

[0051] The control cabin 110 is configured to adjust the rotation angle of the rotating support 310 according to the wind direction and wind speed, so as to reduce the load on the wind turbine blade 1000 under the wind direction and wind speed.

[0052] When the fan blade 1000 needs to be transported by air, the detection device 200 detects the wind direction and wind speed and feeds back the data information of the wind direction and wind speed to the control cabin 110. The control cabin 110 collects the wind direction and wind speed information and simulates and calculates the preset angle when the load on the fan blade 1000 is the lowest under the wind direction and wind speed. Then the control cabin 110 outputs a rotation signal to the rotation adjustment component 300 to control the rotation of the rotating support 310 to rotate to the preset angle. The fan blade 1000 rotates with the rotation of the rotating support 310. When the wind direction and wind speed change, the above steps are repeated. The fan blade 1000 can change its own angle under different wind directions and wind speeds, so that the load on the fan blade 1000 during air transportation is lower, the influence of side wind on the fan blade 1000 during air transportation is reduced, the energy consumption of air transportation is reduced, and the transportation efficiency of the fan blade 1000 is guaranteed.

[0053] Compared with the existing land transportation, the air transportation of this solution has no obstacles in the air route, which can ensure safety and reduce transportation time to the greatest extent compared with ground transportation, and speed up the transportation and assembly of wind turbines. It should be noted that this solution solves the air transportation of large-area workpieces such as wind turbine blades 1000, avoiding the influence of crosswind on large-area workpieces during air transportation. All workpieces with larger areas can be transported using this solution, which will not be elaborated here.

[0054] In the above description, the rotary bearing 310 corresponds to the model of the fan blade 1000 , and different models of fan blades 1000 will use rotary bearings with different customized hole positions.

[0055] Specifically, it also includes a connecting member 120 , which is installed at the bottom of the aircraft 100 , and the rotating support 310 and the detection device 200 are both arranged on the connecting member 120 .

[0056] The connecting member 120 is arranged at the bottom end of the aircraft 100, so that the center of gravity of the aircraft 100 is stable, ensuring the flight safety of the aircraft 100; the rotating support 310 and the detection device 200 are installed on the connecting member 120, avoiding the influence of the airflow direction on the outer shell of the aircraft 100 due to direct installation on the surface of the aircraft 100, thereby further improving the flight safety.

[0057] Furthermore, the material of the connecting member 120 is steel, and the outer layer of the connecting member 120 is provided with a skin, which has the functions of sealing, heat insulation and anti-aging, etc. The connecting member 120 is connected to the aircraft 100 by super-strong bolts.

[0058] It should be noted that the connecting member 120 is a connecting rod, and at least two connecting members 120 are provided.

[0059] The connecting member 120 is rod-shaped. When air flows toward the connecting member 120 , the air flows backward along its side wall. The rod-shaped connecting member 120 is subject to less wind resistance and has less impact on the airflow, so that the aircraft 100 has low energy consumption and a stable flight state.

[0060] In the above, refer to Figure 3 As shown, the rotation adjustment assembly 300 further includes a connecting seat 320 and a power member 330 .

[0061] The connection seat 320 is installed on the connection member 120 , and the rotary support 310 is rotatably connected to the connection seat 320 .

[0062] The power member 330 is installed on the connecting seat 320 , and an output end of the power member 330 is fixedly connected to the rotating support 310 to drive the rotating support 310 to rotate.

[0063] When the angle of the fan blade 1000 needs to be adjusted, the power part 330 is turned on, and the power part 330 drives the rotating support 310 to rotate, and the fan blade 1000 rotates with the rotation of the rotating support 310. After the fan blade 1000 rotates to a preset angle, the power part 330 is closed, and the fan blade 1000 remains fixed, thereby realizing the adjustment of the angle of the fan blade 1000 by the rotating adjustment component 300.

[0064] Optionally, the power member 330 may be a rotary motor.

[0065] Among them, the installation method of the connecting seat 320 and the connecting member 120 can be a super-strong bolt connection. Any connection method that achieves a detachable connection between the two is within the protection scope of this application and will not be described in detail here.

[0066] Furthermore, a plurality of connection seats 320 may be provided, and the rotating supports 310 and the connection seats 320 correspond one to one, so that a plurality of wind turbine blades 1000 can be installed on the aircraft 100 to realize simultaneous transportation.

[0067] Specifically, refer to Figure 2 As shown, a plurality of ventilation holes 321 are defined on the connection base 320 .

[0068] When the aircraft 100 moves forward, the connection seat 320 moves with the movement of the aircraft 100. When the airflow blows toward the connection seat 320, part of the airflow flows backward along the ventilation hole 321. The opening of the ventilation hole 321 reduces the wind resistance of the connection seat 320 and reduces the flight energy consumption.

[0069] Furthermore, the rotation adjustment assembly 300 also includes a rotation controller, which is connected to the power component 330 and is communicatively connected to the control cabin 110 .

[0070] When it is necessary to adjust the angle of the fan blade 1000, the control cabin 110 outputs a rotation signal to the rotation controller, and the rotation controller outputs an opening signal to the power component 330. The power component 330 turns on and drives the fan blade 1000 to rotate through the rotating support 310. After the fan blade 1000 rotates to a preset angle, the rotation controller outputs a closing signal to the power component 330, and the power component 330 turns off, and the fan blade 1000 remains fixed. The setting of the rotation controller realizes the signal transmission of the control cabin 110 to the power component 330, thereby improving the efficiency of the angle adjustment of the fan blade 1000.

[0071] It should be noted that the rotating support 310 has a mounting portion, see Figure 1 As shown, the extension direction of the mounting portion is consistent with the extension direction of the aircraft 100 , and the mounting portion is used to mount the wind turbine blade 1000 .

[0072] The fan blade 1000 is installed on the mounting portion of the rotating support 310 along the extension direction of the aircraft 100, that is, one end of the fan blade 100 is facing the forward direction of the aircraft 100. At this time, the windward area of ​​the fan blade 1000 is small, and the influence of wind resistance and eddy current is low, so that the flight energy consumption of the aircraft 100 is small, and the stable transportation of the fan blade 1000 is achieved.

[0073] The extension direction of the fan blade aircraft is set so that the wind-receiving cross section of the fan blade in the forward direction is the end cross section. The end cross section of the fan blade is smaller than its side area, and the wind resistance in the forward direction is lower. On this basis, adjusting the side angle of the fan blade can adjust its side wind load to reduce the side wind impact on the blade and ensure transportation efficiency.

[0074] Specifically, the control cabin 110 is configured to: input the cross-sectional information of the fan blade 1000, establish a corresponding model in the simulation modeling software, input the wind direction and wind speed information, use the simulation modeling software to perform aerodynamic analysis on the blades at different angles, use the post-processing program provided by the simulation modeling software to analyze the calculations of all working conditions, obtain the angle with the lowest load under the current wind speed and wind direction, and output it to the rotation controller to control the power component 330 to rotate the fan blade 1000 to the optimal windward angle. Optionally, the simulation modeling software is Bladed software.

[0075] The operating program of the control cabin 110 integrates the calculation of the load characteristics of the fan blade 1000 at different windward angles by the Bladed software. Its basic theory is the blade element theory and the momentum theory. According to the idea of ​​calculus, the blade is divided into infinite equal parts along the distance from the impeller center. The distance of each part from the impeller center is r, and the distance occupied by this part is dr. The dr blade element at r is analyzed as follows:

[0076] The thrust dT generated is:

[0077]

[0078] The torque dQ generated is:

[0079] dQ=4πρωv0a′(1-a)r 3 dr

[0080] In the above formula: B is the blade width; ρ is the air density; v rel is the magnitude of the relative wind speed vector at the blade element; is the inflow angle; c is the chord length of the blade element; C L and C D are the lift coefficient and the drag coefficient respectively; ω refers to the angular velocity corresponding to the horizontal component of the blade velocity at r; v0 refers to the vertical component of the relative wind speed; a' is the tangential induction coefficient; a is the axial induction coefficient.

[0081] By integrating dT and dQ with respect to r, we can get the thrust and torque generated by the entire blade. The thrust T and torque Q are calculated using the blade element theory, and the thrust T and torque Q values ​​at different angles are compared. The angle corresponding to the minimum value is the optimal windward angle.

[0082] Furthermore, the transport device for the wind turbine blades in the embodiment of the present application also includes a plurality of connecting bolts 400, which are used to be arranged at the ends of the blades. A plurality of mounting holes 311 are provided on the rotating support 310, and the connecting bolts 400 are correspondingly plugged into the rotating support 310 through the mounting holes 311, and the connecting bolts 400 are interference fit with the mounting holes 311.

[0083] Before transporting the fan blade 1000, the fan blade 1000 needs to be fixed on the rotating support 310, and the connecting bolt 400 is inserted into the mounting hole 311. The connecting bolt 400 and the rotating support 310 are relatively fixed, and the fan blade 1000 is fixed on the rotating support 310. When the fan blade 1000 needs to be disassembled, the connecting bolt 400 can be pulled out from the rotating support 310. The disassembly and assembly is convenient and the operation is simple.

[0084] It should be noted that, refer to Figure 4 As shown, the plurality of mounting holes 311 are located on the same circumference and are evenly spaced apart.

[0085] The end of the fan blade 1000 is circular, the mounting holes 311 are arranged on the same circumference and are evenly spaced, the corresponding connecting bolts 400 are arranged on the same circumference and are evenly spaced, and the mounting holes 311 and the connecting bolts 400 are both arranged on the circumference, so that the fan blade 1000 is evenly stressed, thereby improving the stress stability of the fan blade 1000.

[0086] Furthermore, the aircraft 100 is an airship, which includes a hull 130 , a tail 140 and a power device 150 .

[0087] Among them, the control cabin 110 is arranged on the hull 130; the tail wing 140 is arranged at the rear end of the hull 130, and the tail wing 140 is configured to receive the control signal of the control cabin 110 and rotate when the hull 130 needs to change the flight attitude; the power device 150 is arranged on the hull 130, and is used to supply power to the hull 130.

[0088] The power unit 150 provides power for the hull 130. The aircraft needs to adjust the flight attitude of the hull 130 many times during the flight. The control cabin 110 outputs a control signal to the tail 140, and adjusts the aircraft state by controlling its rotation, thereby achieving the maneuverability of the aircraft 100.

[0089] Furthermore, the suspension characteristics of the airship itself determine the fuel economy. The wind turbine blade 1000 transportation device of the present application can be reused for a long time and can be responsible for multiple wind power sectors in a region, greatly reducing the transportation cost of the wind turbine blade 1000.

[0090] Among them, the power device 150 can be a propeller, and there can be multiple groups of propellers on the hull 130. According to the speed requirements of the hull 130, 2, 4 or 6 propellers can be installed, and each group of propellers is fixed on both sides of the hull 130 respectively.

[0091] Specifically, the hull 130 is a sphere with an elliptical cross section. The elliptical hull 130 can provide the hull 130 with a larger gas loading space, and the load can reach the maximum after being filled with low-density gas. In some examples, the airship has a lifting capacity of 20 tons or more after being filled with buoyancy gas.

[0092] Furthermore, an airship control sensor is provided in the control cabin 110, and the airship control sensor is used to control the displacement of the propulsion, the rotation of the tail 140 and send a control signal to the rotation controller.

[0093] The transport device for the fan blades provided in this application refers to Figure 5As shown, when the fan blade 1000 needs to be transported by air, the detection device 200 detects the wind direction and wind speed and feeds back the data information of the wind direction and wind speed to the control cabin 110. The control cabin 110 collects the wind direction and wind speed information and simulates and calculates the preset angle when the load on the fan blade 1000 is the lowest under the wind direction and wind speed. Then the control cabin 110 outputs a rotation signal to the rotation adjustment component 300 to control the rotation motor to drive the rotation support 310 to rotate to the preset angle. The fan blade 1000 rotates with the rotation of the rotation support 310. The control cabin 110 outputs a rotation signal to the tail wing 140 to control the rotation of the tail wing 140 to adjust the angle of the hull 130. The above steps are repeated when the wind direction and wind speed change. The wind turbine blades 1000 and the aircraft 100 can change their own angles under different wind directions and wind speeds, so that the load on the wind turbine blades 1000 during air transportation is lower, thereby reducing the impact of side winds on the wind turbine blades 1000 and the aircraft 100 during air transportation, reducing the energy consumption of air transportation, and ensuring the transportation efficiency of the wind turbine blades 1000.
