Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wind turbine blade installation, and particularly relates to a guiding device for single-blade floating installation of a wind turbine. BACKGROUND

[0002] In the installation process of a wind turbine, single-blade floating installation is a challenging and crucial link. Since the wind turbine is usually installed at a high position, the single blade is in a suspended and unstable state during floating installation, and the accuracy and safety of installation are directly related to the operation efficiency and service life of the entire wind turbine.

[0003] The common single-blade floating installation guiding device for a wind turbine in the market has obvious deficiencies in the traction mechanism. Most devices adopt a single-rope traction mode, and this single-side force traction mode is prone to cause the blade to swing or rotate during installation, making it difficult for the blade to move smoothly along the predetermined path. This not only increases the risk of collision between the blade and the surrounding structure during installation, causing damage to the blade, but also seriously affects the safety of high-altitude operation, bringing great safety hazards to the installation personnel. SUMMARY

[0004] The purpose of the present application is to provide a guiding device for single-blade floating installation of a wind turbine, which can realize precise control of double-rope synchronous traction, realize quick and standardized connection of the steel wire rope and the blade, simplify the installation process and improve safety.

[0005] In order to achieve the above purpose, the present application adopts the following technical scheme: A guiding device for single-blade floating installation of a wind turbine, comprising a device frame, two winding mechanisms are arranged in the interior of the device frame, two guiding and positioning mechanisms are symmetrically arranged on the same side wall of the device frame, the two guiding and positioning mechanisms are one-to-one corresponding to the two winding mechanisms and are located on the steel wire rope outgoing side of the corresponding winding mechanism, a connecting and limiting assembly is arranged on the end of the steel wire rope away from the winding mechanism, and the two winding mechanisms synchronously wind and unwind the steel wire rope to complete the floating installation of the blade.

[0006] Preferably, a driving mechanism is arranged on the exterior of the device frame, the driving mechanism is connected with the two winding mechanisms, two fixing mechanisms are arranged on the side wall of the device frame, the fixing mechanisms are used for fixing the device frame in the interior of the unit seat cylinder, a protection mechanism is arranged on the outer wall of the device frame, and the protection mechanism is located on the outer side of the driving mechanism.

[0007] Preferably, the winding mechanism includes a winding wheel, which is disposed inside the device frame. A rotating shaft is provided through the winding wheel and is fixedly connected to the winding wheel. One end of the rotating shaft is rotatably connected to the inner wall of the device frame, and the other end of the rotating shaft passes through the inner wall of the device frame and extends to the outside of the device frame. A steel wire rope is connected to the outer circumference of the winding wheel, and the end of the steel wire rope away from the winding wheel passes through the inner wall of the device frame and extends to the outside of the device frame.

[0008] Preferably, the guiding and positioning mechanism includes two positioning sleeves and two redirecting wheels. The redirecting wheels are disposed on the inner wall of the device frame, and the wire rope passes around the redirecting wheels. The two positioning sleeves are disposed on the side wall of the device frame, and the wire rope passes through the positioning sleeves.

[0009] Preferably, the connecting limiting assembly includes a positioning pin, which is connected to the end of the wire rope away from the reel, and a limiting sleeve is connected to the end of the positioning pin away from the wire rope, the limiting sleeve being threaded onto the outside of the positioning pin.

[0010] Preferably, the drive mechanism includes a fixed plate, which is disposed on the outer wall of the device frame. A motor is disposed on the side wall of the fixed plate, and gears are sleeved on the side walls of the two rotating shafts. The two gears mesh with each other, and the output shaft of the motor passes through the fixed plate and is connected to the end of one of the rotating shafts.

[0011] Preferably, the fixing mechanism includes a fixing block, which is disposed on the outer wall of the device frame. A threaded rod is provided through the fixing block, and the threaded rod is threadedly connected to the fixing block. One end of the threaded rod is connected to a clamping block, and the other end of the threaded rod is connected to a handle.

[0012] Preferably, the protective mechanism includes a protective box located outside the drive mechanism. The protective box has a cover on its outer side, the upper end of which is hinged to the protective box via a hinge, and a latch lock is installed at the lower end of the cover, which is connected to the protective box.

[0013] Preferably, two guide rods are connected to the side wall of the clamping block near the fixing block. The two guide rods are symmetrically arranged on both sides of the threaded rod, and the guide rods pass through the fixing block and are slidably connected to the fixing block.

[0014] Preferably, the surface of the abutment block away from the threaded rod is provided with an anti-slip pad.

[0015] The beneficial effects of this invention are: The motor in the drive mechanism drives the rotating shaft to rotate, which in turn drives two meshing gears to move synchronously. This enables the two reels to operate in completely synchronized forward and reverse directions, thereby precisely controlling the length and speed of the two wire ropes. This dual-rope synchronous traction mechanism effectively avoids the swaying or rotation caused by uneven force on one side during the floating installation of the blades. Combined with the guiding and positioning function of the positioning sleeve for the wire ropes, it ensures that the blades can move smoothly along the predetermined path, greatly reducing the risk of collisions during installation and significantly improving the safety of high-altitude operations.

[0016] By using the insertion and engagement of the positioning pin with the second screw hole on the blade, and the threaded fastening of the limiting sleeve, a standardized quick connection interface is formed. This design allows the assembly and disassembly of the wire rope and the blade to be completed without special tools. It avoids the complicated binding operations in traditional hoisting and eliminates the risk of rope slippage. The entire traction process only requires the control of a single motor to achieve synchronous operation of the two ropes. This simplifies the blade positioning operation that traditionally requires multiple people to cooperate into a standardized process that can be monitored by a single person, significantly improving installation efficiency.

[0023] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] like Figures 1-5 As shown, a guide device for floating installation of a single blade of a wind turbine includes a device frame 5, a winding mechanism, a drive mechanism, a fixing mechanism, a guide and positioning component, a connection and limiting component, and a protective mechanism.

[0025] The device frame 5 is located inside the unit base cylinder 1. The device frame 5 is equipped with two winding mechanisms. Two guide positioning mechanisms are symmetrically arranged on the same side wall of the device frame 5. The two guide positioning mechanisms correspond one-to-one with the two winding mechanisms and are located on the wire rope 12 exit side of the corresponding winding mechanism. The end of the wire rope 12 away from the winding mechanism is equipped with a connecting limiting component. The two winding mechanisms simultaneously wind and unwind the wire rope to complete the floating installation of the blade.

[0026] A drive mechanism is provided on the outside of the device frame 5. The drive mechanism is connected to two winding mechanisms and provides power to the winding mechanisms to realize the winding and unwinding of the wire rope 12. Two fixing mechanisms are provided on the side wall of the device frame 5 to fix the device frame 5 inside the unit base cylinder 1. A protective mechanism is fixed on the outer wall of the device frame 5. The protective mechanism is located outside the drive mechanism and is used to protect the drive mechanism from the influence of the external environment.

[0027] The winding mechanism includes a wire rope 12, a reel 20, and a shaft 21.

[0028] The guide and positioning assembly includes two positioning sleeves 18 and two steering wheels 19.

[0029] The connecting limit assembly includes a positioning pin 13 and a limit sleeve 14.

[0030] The reel 20 is located inside the device frame 5. The reel 20 is used to wind and unwind the wire rope 12. A rotating shaft 21 is passed through the reel 20 and is fixedly connected to the reel 20. One end of the rotating shaft 21 is rotatably connected to the inner wall of the device frame 5, and the other end of the rotating shaft 21 passes through the inner wall of the device frame 5 and extends to the outside of the device frame 5. The wire rope 12 is fixedly connected to the outer circumference of the reel 20. The wire rope 12 is used to pull the blade 2 to achieve the floating installation of a single blade.

[0031] Two positioning sleeves 18 (one for each guide positioning component) are fixedly connected to the side wall of the device frame 5, and two redirecting wheels 19 (one for each guide positioning component) are installed on the inner wall of the device frame 5. The wire rope 12 passes around the redirecting wheels 19, and the wire rope 12 is redirected by the redirecting wheels 19, while avoiding wear on the wire rope 12 at bends. The positioning sleeves 18 are used to guide and position the wire rope 12 to ensure that it moves along a predetermined path.

[0032] The end of the wire rope 12 away from the reel 20 passes through the inner wall of the device frame 5 and extends to the outside of the device frame 5. The wire rope 12 passes through the first screw hole 3 on the unit base cylinder 1 and passes through the positioning sleeve 18. The end of the wire rope 12 away from the reel 20 is fixedly connected to the positioning pin 13. The end of the positioning pin 13 away from the wire rope 12 is connected to the limit sleeve 14. The limit sleeve 14 prevents the positioning pin 13 from coming out of the second screw hole 4 and plays a limiting role. The limit sleeve 14 is threaded on the outside of the positioning pin 13. The positioning pin 13 is inserted into the second screw hole 4 on the blade 2.

[0033] The drive mechanism includes a fixed plate 23, a motor 24, and a gear 22.

[0034] The fixing plate 23 is fixedly connected to the outer wall of the device frame 5. The motor 24 is installed on the side wall of the fixing plate 23, and the fixing plate 23 provides mounting support for the motor 24. Gears 22 are fixedly sleeved on the side walls of the two rotating shafts 21. The two gears 22 mesh with each other. The output shaft of the motor 24 passes through the fixing plate 23 and is fixedly connected to the end of one of the rotating shafts 21. The rotating shaft 21 provides rotational support for the winding wheel 20. By starting the motor 24, the rotating shaft 21 can be driven to rotate, which in turn drives the gear 22 to rotate. Since the two gears 22 mesh with each other, they can rotate synchronously, which can drive the two rotating shafts 21 to rotate synchronously. The rotating shafts 21 drive the two winding wheels 20 to rotate synchronously, thereby synchronously winding the two wire ropes 12.

[0035] The protective mechanism includes a protective box 6, a hinge 7, a box cover 8, and a latch lock 9.

[0036] The protective box 6 is fixed to the outer wall of the device frame 5. The protective box 6 is located outside the drive mechanism. The protective box 6 is used to protect the drive mechanism and prevent it from being affected by the external environment. The protective box 6 is provided with a cover 8 on the outside. The cover 8 is used to open and close the protective box 6 to facilitate the inspection and maintenance of the drive mechanism. The upper end of the cover 8 is hinged to the protective box 6 through a hinge 7. The lower end of the cover 8 is equipped with a latch lock 9. The latch lock 9 is connected to the protective box 6 and is used to fix the cover 8 to the protective box 6 to ensure the stability of the cover 8 when it is closed.

[0037] The fixing mechanism includes a fixing block 10, a clamping block 11, a threaded rod 15, a throttle 16, and a guide rod 17.

[0038] The fixing block 10 is fixedly connected to the outer wall of the device frame 5. A threaded rod 15 is provided through the fixing block 10. The threaded rod 15 is threadedly connected to the fixing block 10. One end of the threaded rod 15 is rotatably connected to a pressing block 11. An anti-slip pad is fixed on the surface of the pressing block 11 away from the threaded rod 15. The anti-slip pad can effectively enhance the anti-slip property and improve the stability of the pressing block 11 pressing against the unit seat 1. The other end of the threaded rod 15 is fixedly connected to a handle 16. After the device frame 5 is placed inside the unit seat 1, the threaded rod 15 is driven to rotate by rotating the handle 16. Since the threaded rod 15 is threadedly connected to the fixing block 10, the threaded rod 15 can move. The movement of the threaded rod 15 drives the pressing block 11 to press against the inner wall of the unit seat 1, thereby fixing the device frame 5. Two guide rods 17 are fixedly connected to the side wall of the clamping block 11 near the fixed block 10. The guide rods 17 restrict the clamping block 11 to move only in a straight line to ensure the stability of its movement. The two guide rods 17 are symmetrically arranged on both sides of the threaded rod 15. The guide rods 17 pass through the fixed block 10 and are slidably connected to the fixed block 10.

[0039] When using this invention, first place the device frame 5 inside the unit base 1, insert the positioning sleeve 18 into the first screw hole 3 on the unit base 1, and drive the threaded rod 15 to rotate in the fixed block 10 by rotating the handle 16. Since the threaded rod 15 is threadedly connected to the fixed block 10, the threaded rod 15 pushes the pressing block 11 to move towards the inner wall of the unit base 1. The anti-slip rubber pad on the surface of the pressing block 11 enhances the friction, thereby firmly fixing the device frame 5. The blade 2 is then hoisted to the vicinity of the unit base 1. The positioning pin 13 is then inserted into the second screw hole 4 and secured with the threaded limit sleeve 14 to prevent it from coming out. The motor 24 in the drive mechanism is then started. The output shaft of the motor 24 drives one of the rotating shafts 21 to rotate, and the gear 22 on the rotating shaft 21 rotates accordingly. Since the two gears 22 mesh with each other, the other rotating shaft 21 rotates synchronously in the opposite direction. The two rotating shafts 21 drive the two winding wheels 20 to rotate inside the device frame 5. The winding wheels 20 wind up the wire rope 12. As the wire rope 12 is gradually wound up, the blade 2 is smoothly pulled to the floating installation position. Then, the positioning pin 13 is inserted into the first screw hole 3 on the unit base 1 to position the blade 2 on the unit base 1. The blade 2 can then be connected to the unit base 1 with bolts. After the blade 2 is installed in place, the reverse motor 24 can be used to loosen the wire rope 12. After removing the positioning pin 13, the floating installation of the single blade is completed. Then, the state of the clamping block 11 being fixed to the unit base 1 is released, and the device frame 5 is removed.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
