[0041] Through the above technical solution, the fan blade posture adjusting device provided by the first aspect of the present application is provided with the blade root support 1 and the blade body support 2 to support the blade root and the blade body part of the fan blade 3 respectively, so that the fan blade 3 can be better supported to prevent the fan blade 3 from being broken during transportation; wherein the blade root rotation adjusting device 11 and the blade root receiving plate 12 are arranged in the blade root support 1 to support the blade root part through the blade root receiving plate 12, and the blade root is connected with the blade root rotation adjusting device 11, so that the fan blade 3 can be driven by the blade root rotation adjusting device 11 to rotate around the axis to adjust the posture of the fan blade, so that in the normal state, the fan blade is in the posture of the front edge vertically downward and the rear edge vertically upward, so that the blade body can be in contact with the blade body support 2 from the front edge part with greater structural strength, to ensure that the blade is not easy to be structurally damaged; and when the blade encounters height limitation during transportation, the fan blade 3 can be adjusted to be in the horizontal direction at the front edge and the rear edge, so as to pass through the height-limited section, and after passing through the height-limited section, the fan blade 3 is adjusted to be in the posture of the front edge vertically downward and the rear edge vertically upward, to ensure that the fan blade 3 is not easy to be structurally damaged; in addition, the blade body roller set 22 is arranged on the blade body support 2, so that the blade body roller 221 in the blade body roller set 22 can rotate under the driving of the blade body of the fan blade 3 when the fan blade 3 is driven by the blade root rotation adjusting device 11 to rotate, so as to facilitate the rotation of the fan blade 3 to realize posture adjustment, and the energy consumed for adjusting the posture of the fan blade 3 can be reduced.

[0042] Specifically, in one embodiment of the fan blade posture adjusting device provided by the first aspect of the present application, as shown in Figure 1As shown, the blade root support 1 further comprises a blade root support base 13 and a blade root lifting device 14, one end of the blade root receiving plate 12 is hinged to the blade root support base 13, the other end is connected to the blade root lifting device 14, and the blade root rotation adjusting device 11 is arranged at the end of the blade root receiving plate 12 hinged to the blade root support base 13, so that the blade root receiving plate 12 can be adjusted up and down under the extension and retraction of the blade root lifting device 14, so as to realize the vertical or horizontal adjustment of the fan blade 3, so that the fan blade 3 can be erected when encountering a building group or being in a valley area during transportation, so as to avoid the collision between the tip of the fan blade 3 and the building or the hillside, and to avoid the damage of the fan blade 3, so as to ensure the convenience of the fan blade 3 during transportation and to avoid the damage of the fan blade 3 during transportation; It can be understood that the blade root lifting device 14 can be provided as a hydraulic cylinder, and the hydraulic cylinder is hinged between the blade root support base 13 and the blade root receiving plate 12, in addition, the blade root rotation adjusting device 11 and the blade root receiving plate 12 can be fixedly connected, so that the linkage control of the blade root rotation adjusting device 11 can be realized only by controlling the blade root receiving plate 12 through the blade root lifting device 14; The blade root rotation adjusting device 11 can also be hinged between the blade root receiving plate 12 or the blade root support base 13, and the blade root rotation adjusting device 11 is further connected with a lifting device capable of controlling the up and down rotation adjustment of the blade root rotation adjusting device 11, so that the angle between the blade root rotation adjusting device 11 and the blade root receiving plate 12 can be adjusted, so that the blade root of the fan blade 3 of different sizes can be well received by the blade root receiving plate 12 after being connected with the blade root rotation adjusting device 11.

[0043] Further, in one embodiment of the fan blade posture adjusting device provided in the first aspect of the present application, the blade root rotation adjusting device 11 comprises a variable pitch bearing and a motor connected with the variable pitch bearing, the blade root of the fan blade 3 is connected with the variable pitch bearing, specifically, the outer ring of the variable pitch bearing is set as a fixed ring, the inner ring of the variable pitch bearing is set as a movable ring, the blade root of the fan blade 3 is screwed with the movable ring, the inner diameter of the movable ring is provided with a gear structure, and the output shaft of the motor is provided with a gear structure matched with the gear structure on the inner diameter of the movable ring, so that the motor can drive the movable ring of the variable pitch bearing to rotate, thereby realizing the axial rotation adjustment of the fan blade 3 itself.

[0044] Further, in one embodiment of the fan blade posture adjusting device provided in the first aspect of the present application, as shown in Figure 2As shown, the moving ring limiting block 1111 can be arranged on the moving ring 111 of the variable pitch bearing, and the fixed ring limiting block 1121 can be arranged on the fixed ring 112 of the variable pitch bearing, so as to limit the rotation angle of the moving ring 111 through the cooperation of the moving ring limiting block 1111 and the fixed ring limiting block 1121. Specifically, one moving ring limiting block 1111 can be arranged on the moving ring 111, two fixed ring limiting blocks 1121 can be arranged on the fixed ring 112, and preferably, the two fixed ring limiting blocks 1121 are spaced 180° apart, and the line between the two fixed ring limiting blocks 1121 is in a horizontal state. In addition, the moving ring limiting block 1111 needs to be arranged at a region above the two fixed ring limiting blocks 1121. When the wind turbine blade 3 is hoisted onto the wind turbine blade posture adjusting device (when the wind turbine blade 3 is hoisted, the posture is generally that the leading edge is inclined downward and the trailing edge is inclined upward), the moving ring limiting block 1111 can be preferably rotated to a position corresponding to the trailing edge of the wind turbine blade 3, so that when the moving ring limiting block 1111 is located between the two fixed ring limiting blocks 1121, the wind turbine blade 3 is in a posture that the leading edge is inclined downward and the trailing edge is inclined upward, or in a posture that the leading edge is vertical downward and the trailing edge is vertical upward. When the moving ring limiting block 1111 contacts any fixed ring limiting block 1121, the wind turbine blade 3 can be in a posture that the leading edge and the trailing edge are in a horizontal direction, so as to avoid the posture that the trailing edge with low structural strength is downward, so as to ensure that the wind turbine blade 3 is in a reasonable posture, avoid structural damage, and the fixed ring limiting block 1121 can assist in stopping the rotation of the moving ring 111.

[0045] Further, in one embodiment of the wind turbine blade posture adjusting device provided in the first aspect of the present application, as shown in Figure 5As shown, the blade root roller set is arranged on the blade root receiving plate 12, and the blade root roller 121 in the blade root roller set can rotate under the driving of the blade root of the fan blade 3 when the fan blade 3 is driven to rotate along the axial direction by the blade root rotating adjusting device 11, so that the position of the fan blade 3 can be kept unchanged and the fan blade 3 cannot fall off the blade root receiving plate 12, and the rolling friction between the fan blade 3 and the blade root receiving plate 12 (blade root roller set) is generated, so that the motor can drive the moving coil 111 and the fan blade 3 to rotate with smaller power, and the posture adjustment of the fan blade 3 is facilitated. Of course, it can be understood that, in order to prevent the surface of the fan blade 3 from being damaged by indentation and scratch, a rubber layer 4 can be arranged on the surface of the fan blade 3 and the area where the surface of the fan blade 3 contacts the blade root roller 121 of the blade root roller set, so as to avoid the stress concentration and the indentation on the surface of the fan blade 3. In addition, the rubber layer can play a buffering role when the fan blade 3 collides with the blade root receiving plate 12 and the blade root roller set during the process of hoisting and transporting the fan blade 3 to the fan blade posture adjusting device, so as to protect the fan blade 3. Correspondingly, a rubber layer can also be arranged on the surface of the blade root roller 121 of the blade root roller set, so that the rubber layer is deformed and the contact area between the fan blade 3 and the blade root roller 121 is increased when the rubber layer contacts the fan blade 3, thereby avoiding stress concentration and indentation on the surface of the fan blade 3. In addition, the blade root receiving plate 12 can be arranged as an arc plate, so as to better fit the blade root of the fan blade 3, that is, more blade root rollers 121 can contact the blade root of the fan blade 3, and the contact area with the blade root is increased, thereby avoiding stress concentration.

[0046] Further, in one embodiment of the fan blade posture adjusting device provided in the first aspect of the present application, as shown in Figure 1 The blade body support 2 further comprises a blade body lifting device 23, which is arranged to operate synchronously with the blade root lifting device 14, so that the blade body lifting device 23 drives the blade body receiving device 21 and the blade body roller set 22 to ascend when the blade root lifting device 14 drives the blade root receiving plate 12 to rotate upward, and drives the blade body receiving device 21 and the blade body roller set 22 to descend when the blade root lifting device 14 drives the blade root receiving plate 12 to rotate downward, so that the gravity of the fan blade 3 can be uniformly distributed on the blade body receiving device 21 and the blade root receiving plate 12, thereby avoiding the situation that only the blade body receiving device 21 or only the blade root receiving plate 12 receives the fan blade 3, and further avoiding the situation that the fan blade 3 is broken or crushed. Further, as shown in Figure 3 and Figure 4As shown, the blade receiving device 21 further comprises a receiving support 211 connected with the blade lifting device 23 and a blade support plate 212 hinged with the receiving support 211, the hinging of the blade support plate 212 with the receiving support 211 can enable the blade support plate 212 to rotate with the up and down rotation of the fan blade 3 when the fan blade 3 rotates up and down, so as to ensure the good adhesion with the blade of the fan blade 3 and form good support to the fan blade 3; in addition, the blade lifting device 23 can be a hydraulic cylinder.

[0047] Further, in one embodiment of the fan blade posture adjusting device provided in the first aspect of the present application, as shown in Figure 3 As shown, the blade support plate 212 is an arc-shaped plate, and the blade roller set 22 further comprises a conveying belt 222, the conveying belt 222 is sleeved on the blade of the fan blade 3, and the plurality of blade rollers 221 are arranged uniformly and equidistantly between the blade of the fan blade 3 and the conveying belt 222, and the surface roughness is provided on the surface of the conveying belt 222 in contact with the blade support plate 212 and the contact surface of the blade support plate 212 in contact with the conveying belt 222, so that sufficient friction can be generated between the conveying belt 222 and the blade support plate 212, thereby enabling the conveying belt 222 and the blade support plate 212 not to slide relative to each other, and only the blade rollers 221 rotate under the action of the blade of the fan blade 3 and the conveying belt 222, so that the fan blade 3 can rotate, and the conveying belt 222 and the blade support plate 212 can be relatively stationary during rotation to ensure that the fan blade 3 will not fall off the blade support plate 212, thereby ensuring the safety and reliability of the fan blade 3 during rotation; in addition, the blade support plate 212 being an arc-shaped plate can also avoid the fan blade 3 from falling off the blade support plate 212; in addition, it can be understood that, in order to prevent the surface of the fan blade 3 from being easily damaged, such as indentation and scratch, as shown, Figure 4 As shown, a rubber layer 4 can be sleeved on the area of the surface of the fan blade 3 in contact with the blade roller 221, so as to avoid the stress concentration leading to the indentation on the surface of the fan blade 3, in particular, the blade roller 221 between the blade of the fan blade 3 and the conveying belt 222 can be a cylindrical air bag, that is, the blade roller 221 can form a cylindrical shape after inflation, which can play the role of a roller, facilitating the rotation of the fan blade 3, and after the fan blade 3 is rotated to the position, the blade roller 221 between the fan blade 3 and the blade support plate 212 can be appropriately deflated, so that the contact area between the blade roller 221 and the blade of the fan blade 3 can be increased, so as to reduce the stress concentration, and the air bag blade roller 221 can play a better buffering role between the fan blade 3 and the blade support plate 212, thereby avoiding the damage to the surface of the blade of the fan blade.

[0048] Optionally, in one embodiment of the fan blade posture adjusting device provided in the first aspect of the present application, as shown in Figure 4 the blade body roller 221 can be directly rotatably connected to the blade body support plate 212, so that when the blade root rotating adjusting device 11 drives the fan blade 3 to rotate around its own axis, the blade body roller 221 can also rotate, so that the fan blade 3 will not fall off the blade body support plate 212, thereby ensuring the safety and reliability of the fan blade 3 during rotation. In addition, the blade body support plate 212 can be an arc-shaped plate, so as to better prevent the fan blade 3 from falling off the blade body support plate 212. Furthermore, it can be understood that, in order to prevent the surface of the fan blade 3 from being damaged, such as being indented or scratched, as shown in Figure 4 a rubber layer 4 can be provided on the area where the surface of the fan blade 3 contacts the blade body roller 221, so as to avoid stress concentration and prevent the surface of the fan blade 3 from being indented. In addition, the rubber layer can also play a buffering role when the fan blade 3 bumps against the blade body support plate 212 and the blade body roller 221 during hoisting and transporting the fan blade 3 to the fan blade posture adjusting device, so as to better protect the fan blade 3. Correspondingly, a rubber layer can also be provided on the surface of the blade body roller 221, so that when the rubber layer is pressed, it deforms to increase the contact area between the fan blade 3 and the blade body roller 221, thereby avoiding stress concentration and preventing the surface of the fan blade 3 from being indented.
