Description

Technical Field

[0001] The utility model relates to the technical field of wind generator blades, in particular to a wind generator blade transport mechanism. Background Art

[0002] Wind power generation is the process of converting the kinetic energy of wind into mechanical energy, and then converting mechanical energy into electrical energy. The device required for wind power generation is called a wind turbine. A wind turbine mainly consists of a wind rotor, a generator, and a tower. The wind rotor is an important component that converts the kinetic energy of wind into mechanical energy. It consists of several blades. When the wind blows towards the blades, the aerodynamic force generated on the blades drives the wind rotor to rotate, driving the generator to generate electricity.

[0003] Among them, the "a wind turbine blade transfer mechanism" disclosed in the authorization number "CN215486381 U" has a specific technical structure setting, and during the transfer process, the blade root is in elastic contact with the first arc-shaped limit plate, the second arc-shaped limit plate and the arc-shaped support plate, thereby reducing friction and damage;

[0004] However, although this wind turbine blade solves the problem of blade damage caused by shaking during transportation, the wind turbine is a large-scale power generation equipment with a long wind blade and a wide fan area. When the transportation equipment encounters a turn during transportation, the blades are longer than the transportation body and the curve angle is smaller, so the transportation equipment needs to be repeatedly operated to transport the blades through the curve, and the lack of an omnidirectional rotating mechanism makes the transportation turning more difficult and easily causes the top of the blade to collide and be damaged.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0023] As introduced in the background technology, there are deficiencies in the prior art. In order to solve the above technical problems, the present application proposes a wind turbine blade transfer mechanism.

[0024] See also Figure 1-Figure 6 A wind turbine blade transfer mechanism includes a blade transfer device 1, a steering adjustment component 2 and a wind turbine blade mechanism 3. The blade transfer device 1 includes a rotating drive base 101 and a hydraulic telescopic rod 102. The rotating drive base 101 is rotatably mounted on one end of the top of the blade transfer device 1.

[0025] Specifically, when the wind turbine blade mechanism 3 encounters a larger curve during transportation, the rotating driving base 101 rotates through the steering adjustment component 2 to drive the wind turbine blade mechanism 3 to rotate toward the inside of the curve, so as to avoid the wind turbine blade mechanism 3 colliding with the mountain wall when the mountain road turns. The output end of the hydraulic telescopic rod 102 is extended to make the steering adjustment component 2 drive the top of the wind turbine blade mechanism 3 to rotate upward, thereby reducing the horizontal length of the wind turbine blade mechanism 3 and reducing the turning difficulty of the blade transportation equipment 1. At the same time, the servo motor 203 drives the wind turbine blade mechanism 3 to rotate through the meshing transmission of the inner gear block 205 and the gear 206, and drives the wind turbine blade mechanism 3 to rotate through the adjusting wheel 204, so that the wider wind turbine blade mechanism 3 rotates to a suitable angle, so as to avoid the wind turbine blade mechanism 3 being damaged by scratches due to the excessive width of the blades during transportation, and solves the problem of the wind turbine blade mechanism 3 being damaged by collision due to the inconvenience of turning when transporting.

[0026] Furthermore, an inner slide groove 207 is provided on the outer side of the adjusting wheel 204, an outer slide groove 208 is provided on the inner wall of the cavity 202, and a plurality of steel balls 209 are rotatably installed between the inner slide groove 207 and the outer slide groove 208;

[0027] Specifically, when the adjusting wheel 204 rotates inside the cavity 202, the steel ball 209 rotates between the inner slide groove 207 and the outer slide groove 208, so that the rotation resistance of the adjusting wheel 204 is reduced, so that the wind turbine blade mechanism 3 is more stable during adjustment and rotation.

[0028] Further, the wind turbine blade mechanism 3 is movably mounted on the other side of the steering adjustment component 2, the other side of the adjustment wheel 204 is fixedly mounted with a connecting shaft 210, one side of the outer surface of the connecting shaft 210 is evenly fixedly mounted with a plurality of L-shaped connecting rods 211, one side of the wind turbine blade mechanism 3 is movably mounted with a connecting component 301, the interior of the connecting component 301 is provided with a plurality of first circular holes 302 and second circular holes 305, the first circular holes 302 are circularly distributed, the L-shaped connecting rods 211 penetrate the second circular holes 305, the other end of the L-shaped connecting rods 211 is screwed with a first nut 212, one side of the wind turbine blade mechanism 3 is evenly fixedly mounted with a plurality of fixing rods 303, the fixing rods 303 penetrate the first circular holes 302, and one end of the fixing rods 303 is screwed with a second nut 304;

[0030] Specifically, when the wind turbine blade mechanism 3 needs to be transported, the wind turbine blade mechanism 3 is lifted by a lifting equipment, and then the fixing rod 303 is extended through the first circular hole 302 to one side of the connecting component 301, and the second nut 304 is rotated and connected to one end of the fixing rod 303, so that the wind turbine blade mechanism 3 is fixedly installed on the other side of the connecting component 301, and then the L-shaped connecting rod 211 is extended through the second circular hole 305 to the other side, and the first nut 212 is rotated and installed on the other end of the L-shaped connecting rod 211, so that the connecting component 301 is fixedly installed on the other side of the steering adjustment component 2. At this time, the connecting shaft 210 and the fixing ring 306 extend to the inside of the second groove 307, so that the wind turbine blade mechanism 3 is stably fixedly installed on the other side of the steering adjustment component 2 for transportation.

[0031] Furthermore, a support frame 4 is fixedly installed on the top of the blade transfer device 1, and the support frame 4 includes a clamping rod 401, a clamping plate 402, a spring 403 and a rubber pad 404.

[0032] Furthermore, the rubber pad 404 is fixedly mounted on the side of the clamping plate 402 close to each other, and the top ends of the clamping plate 402 and the rubber pad 404 are inclined surfaces;

[0033] Specifically, when the blade transfer equipment 1 is traveling in a straight line, the wind turbine blade mechanism 3 rotates downward, and since the top ends of the clamping plate 402 and the rubber pad 404 are inclined, after being squeezed by the wind turbine blade mechanism 3, the clamping rod 401 slides outward at the front and rear ends of the support frame 4. At this time, the clamping plate 402 opens, and the wind turbine blade mechanism 3 rotates downward to between the clamping plates 402. The rubber pad 404 contacts the surface of the wind turbine blade mechanism 3, and the elastic force of the spring 403 makes the clamping plate 402 firmly clamp and fix the wind turbine blade mechanism 3. The root of the wind turbine blade mechanism 3 is supported by the support frame 4, so that the wind turbine blade mechanism 3 is more stable during transportation.

[0034] Working principle: When the wind turbine blade mechanism 3 encounters a large curve during transportation, the wind turbine blade mechanism 3 is driven to rotate horizontally to the inside by rotating the driving base 101 to avoid the top of the wind turbine blade mechanism 3 colliding with the mountain wall during the process. The output end of the hydraulic telescopic rod 102 extends to drive the top of the wind turbine blade mechanism 3 to rotate upward, thereby reducing the difficulty of transportation and turning of the blade transfer equipment 1. The servo motor 203 drives the inner gear block 205 and the gear 206 to rotate, so that the adjusting wheel 204 drives the wind turbine blade mechanism 3 to adjust and rotate, thereby avoiding the situation where the blades of the wind turbine blade mechanism 3 are too wide and cause collision during transportation.
