Description

Technical Field

[0001] This utility model relates to the field of wind power generation technology, specifically an adjustment device for hoisting wind turbine blades. Background Technology

[0002] Wind power generation is a method of generating electricity by converting wind energy into electrical energy. It is mostly achieved through wind turbine generator sets, which can be roughly divided into three parts: wind turbine, generator, and tower. The wind turbine generator is composed of several blades. The blades of large wind turbine generator sets are generally hoisted and installed individually. During the hoisting process, because the blades are long and the required hoisting height is generally over 100 meters, the blades are prone to significant swaying at high altitudes, making it inconvenient for personnel to carry out installation work. Furthermore, large tower cranes are often used during hoisting, making it difficult and inconvenient to perform precise positional adjustments on the blades. Utility Model Content

[0003] The purpose of this invention is to provide an adjustment device for hoisting wind turbine blades, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] An adjustment device for hoisting wind turbine blades, comprising:

[0006] The system includes a suspended platform, a stabilizing mechanism to stabilize the blade position, multiple fixing mechanisms to fix the blade, and multiple moving mechanisms. Multiple lifting rings are fixedly connected to the top surface of the suspended platform. The stabilizing mechanism is fixedly connected to the bottom surface of the suspended platform. Each stabilizing mechanism includes two fixing boxes, each with a connecting ring fixedly connected to both ends. Each fixing box contains an automatic winch, and each winch is equipped with two cables. The top ends of the four cables are fixedly connected to the four corners of the bottom surface of the suspended platform. The multiple fixing mechanisms are located below the suspended platform, and the multiple moving mechanisms correspond one-to-one with the multiple fixing mechanisms. All the multiple moving mechanisms are slidably engaged with the suspended platform.

[0007] Its characteristic is that the fixing mechanism includes:

[0008] The system comprises two plates, a movable plate, a rotating plate, a slide rail, and two abutments. The two plates are arranged vertically in sequence, with a support plate rotatably connected to one end of each plate. The movable plate is located between the two plates, and its opposite sides are rotatably connected to one end of each of the two support plates. One side of the movable plate has multiple threaded holes, and each threaded hole contains a threaded rod. One end of the rotating plate is rotatably connected to the other end of one plate, and the other ends of each opposite side of the rotating plate have locking holes. The slide rail is fixedly connected to the other end of the other plate, and an adjusting screw is rotatably connected between its two ends. The two abutments each have one end slidably locked inside the slide rail, and each end of the two abutments has a screw-in hole. The inner sidewalls of the two screw-in holes are screwed into the outer sidewalls of the adjusting screw. Each adjacent side of the two abutments is fixedly connected to a locking rod, and the two locking rods are movably inserted into the two locking holes.

[0009] The feature is that: a drive box is fixedly connected to one end of the slide rail, and a drive motor is provided inside the drive box, and the motor shaft of the drive motor is fixedly connected to one end of the adjusting screw.

[0010] The feature is that the moving mechanism includes:

[0011] The rod and slider are connected in a rotatable manner. The bottom end of the rod is rotatably connected to the top surface of another plate on the corresponding fixed mechanism. The slider is fixedly connected to the top end of the rod. The top surface of the hanging plate is provided with multiple sliding grooves, and the multiple sliding grooves correspond one-to-one with multiple moving mechanisms. The slider is slidably engaged in the corresponding sliding groove.

[0012] The feature is that: two electric push rods are fixedly connected to the bottom surface of each slider, and the movable ends of the two electric push rods are in contact with the top surface of the adjacent plate. The two electric push rods are located on opposite sides of the rod body.

[0013] The features are as follows: an adjusting screw is rotatably connected between the two ends of any sliding groove; multiple power boxes are fixedly connected to one side of the hanging plate; each power box is equipped with a power motor, and the multiple power motors correspond one-to-one with the multiple sliding grooves; the motor shaft of each power motor is fixedly connected to one end of the adjacent adjusting screw; a circular hole is opened at one end of each slider; a thread is opened on the inner side wall of each circular hole; and the inner side wall of each circular hole is screwed into the outer side wall of the adjacent adjusting screw through the thread.

[0014] Its characteristic is that: the two plates are fixedly connected to abutment pads on adjacent sides and one side of the rotating plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By hooking the crane hook onto the lifting ring, fixing two fixed boxes to the ground using connectors, and embedding the blade between two plates on multiple fixed mechanisms, the rotating plate is rotated to position it between two adjacent abutment plates. Then, the drive motor is activated to rotate the adjusting screw, causing the two adjacent abutment plates to clamp the rotating plate and the locking rod to engage with the locking hole. The threaded rod is then rotated to contact the blade, fixing it to the multiple fixed mechanisms. The motor is then activated to move the lifting plate and blade upwards. During the lifting process, an automatic winch releases the cable, keeping it taut and thus maintaining the stability of the lifting plate, preventing swaying. Once the blade has moved to the appropriate height, the movable ends of two electric push rods on multiple moving mechanisms are activated to move synchronously in opposite directions, causing the blade to deflect. The drive motor can also be activated to rotate the adjacent adjusting screw, causing the adjusting screw to move the adjacent slider, fixed mechanism, and blade synchronously laterally, allowing for precise adjustment of the blade position and facilitating blade installation.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 In this embodiment of the present invention, an adjustment device for hoisting wind turbine blades includes:

[0024] The device comprises a suspended platform 100, a stabilizing mechanism 200 for stabilizing the blade position, multiple fixing mechanisms 300 for fixing to the blade, and multiple moving mechanisms 400. Multiple lifting rings 101 are fixedly connected to the top surface of the suspended platform 100. The stabilizing mechanism 200 is fixedly connected to the bottom surface of the suspended platform 100. The stabilizing mechanism 200 includes two fixing boxes 210, and each of the two fixing boxes 210 has a connecting ring 211 fixedly connected to both ends. Each of the two fixing boxes 210 has an automatic winch, and each of the two automatic winches has two cables 220. The top ends of the four cables 220 are fixedly connected to the four corners of the bottom surface of the suspended platform 100. The multiple fixing mechanisms 300 are located below the suspended platform 100. The multiple moving mechanisms 400 correspond one-to-one with the multiple fixing mechanisms 300, and the multiple moving mechanisms 400 are slidably engaged with the suspended platform 100.

[0025] Specifically, the blades are fixed to multiple fixing mechanisms 300, and then the crane hook is hooked onto the lifting ring 101 to connect the crane to the suspended plate 100. Then, ground nails are driven into the ground through the connecting ring 211 to fix the two fixing boxes 210 to the ground. Then, the motor is started to lift the suspended plate 100, which drives the multiple fixing mechanisms 300 and the blades to a designated height. At the same time, two automatic winches are started to release adjacent cables 220, keeping the cables 220 taut and pulling the suspended plate 100. This reduces the large swaying of the blades due to wind and other forces, thus keeping the suspended plate 100 in a relatively stable state during the upward movement, making it easier for users to install the blades. Example 1

[0026] like Figure 2-4 As shown, in this embodiment, the fixing mechanism 300 includes:

[0027] The system comprises two plates 310, a movable plate 320, a rotating plate 330, a slide rail 340, and two abutment plates 350. The two plates 310 are arranged vertically in sequence, and each plate 310 is rotatably connected to a support plate 311 at one end. The movable plate 320 is located between the two plates 310, and its opposite sides are rotatably connected to one end of each of the two support plates 311. Multiple threaded holes are provided on one side of the movable plate 320, and threaded rods 321 are screwed into each of these holes. One end of the rotating plate 330 is rotatably connected to the other end of one plate 310, and the other ends of the rotating plate 330 on opposite sides are provided with locking holes. The slide rail 340 is fixedly connected to the other end of the other plate 310. An adjusting screw 341 is rotatably connected between the two ends of the slide rail 340. Two abutments 350 are slidably engaged inside the slide rail 340 at one end, and each abutment 350 has a screw hole at one end. The inner sidewall of the two screw holes is screwed into the outer sidewall of the adjusting screw 341. A locking rod 351 is fixedly connected to the adjacent side of each abutment 350, and the two locking rods 351 are respectively movably inserted into the two locking holes. A drive box 342 is fixedly connected to one end of the slide rail 340, and a drive motor is installed inside the drive box 342. The motor shaft of the drive motor is fixedly connected to one end of the adjusting screw 341. An adjusting screw 440 is rotatably connected between the two ends inside any slide groove.

[0028] In this embodiment, initially, neither of the rotating plates 330 on any of the fixing mechanisms 300 is in contact with the adjacent abutment plates 350, and there is no obstruction between the other ends of the two adjacent plates 310. Then, the blade can be inserted between the other ends of the two adjacent plates 310, and the rotating plate 330 is rotated to the position of the adjacent abutment plate 350. The adjusting screw 341 is a forward and reverse thread screw; when the adjusting screw 341 rotates, it can drive the two adjacent abutment plates 350 to move synchronously towards or away from each other. By starting the drive motor to rotate the adjacent adjusting screw 341, the two abutment plates 350 are brought into contact with the adjacent rotating plate 330, and the locking rod 351 on the abutment plate 350 is engaged with the adjacent rotating plate 330. Inside the locking holes on the rotating plate 330, multiple threaded rods 321 are rotated to contact the blade. The ends of the threaded rods 321 that contact the blade are covered with a rubber layer to prevent damage to the blade surface. The blade is then pressed tightly against the rotating plate 330 by the multiple threaded rods 321, thus fixing the blade between the two plates 310. After the blade is installed, the drive motor on any of the fixing mechanisms 300 can be started to drive the adjacent adjusting screw 341 to rotate, causing the two adjacent abutment plates 350 to disengage from the adjacent rotating plate 330. This causes the rotating plate 330 to rotate naturally due to its own weight, allowing the fixing mechanism 300 to naturally release the blade, making it easier for the fixing mechanism 300 to detach from the blade.

[0029] like Figure 2-3 As shown, in this embodiment, the moving mechanism 400 includes:

[0030] The rod 410 and slider 420 are connected. The bottom end of the rod 410 is rotatably connected to the top surface of another plate 310 on the corresponding fixing mechanism 300. The slider 420 is fixedly connected to the top end of the rod 410. The top surface of the hanging plate 100 has multiple sliding grooves, and each groove corresponds to one of the multiple moving mechanisms 400. The slider 420 is slidably engaged in the corresponding groove. Two electric push rods 430 are fixedly connected to the bottom surface of each slider 420, and the movable ends of the two electric push rods 430 are in contact with the top surface of the adjacent plate 310. Two electric push rods 430 are located on opposite sides of the rod body 410. Multiple power boxes 441 are fixedly connected to one side of the hanging plate 100. Each power box 441 is equipped with a power motor, and the multiple power motors correspond one-to-one with multiple sliding grooves. The motor shaft of each power motor is fixedly connected to one end of the adjacent adjusting screw 440. Each slider 420 has a circular hole at one end. The inner wall of each circular hole is threaded. The inner wall of each circular hole is screwed into the outer wall of the adjacent adjusting screw 440 through the thread.

[0031] In practice, after the blade is hoisted to the designated height by the lifting plate 100, the two electric push rods 430 on the moving mechanism 400 can be activated to make the movable ends of the two electric push rods 430 move synchronously in opposite directions. This causes the movable ends of the two electric push rods 430 to abut against the deflection part of the adjacent plate 310, thereby causing the blade to deflect through the plate 310 and making a more precise adjustment of the blade position. Then, the power motor is activated to drive the adjacent adjusting screw 440 to rotate, which in turn drives the slider 420 to move, thereby adjusting the position of the plate 310 and the blade, making it easier for users to carry out installation work. Example 2

[0032] Based on Embodiment 1, the blade is more securely fixed to the fixing mechanism 300 by setting a pad 301.

[0033] like Figure 1-4 As shown, in this embodiment, pads 301 are fixedly connected to the adjacent sides of the two plates 310 and the side of the rotating plate 330.

[0034] In practice, the pad 301 can be made of rubber or other materials, which have a large friction with the blade surface, making it difficult for the blade to slide on the fixing mechanism 300. At the same time, the use of soft materials such as the pad 301 to contact the blade surface can reduce the occurrence of scratches on the blade surface.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
