Description

Technical Field

[0001] This invention relates to the field of wind turbine blade installation technology, and in particular to a wind compensation device for wind turbine blade installation site. Background Technology

[0002] The installation of wind turbine blades is a core part of wind farm construction. This process requires precise operation and strict quality control. The hoisting of the blades is a key step in the installation process. Generally speaking, the final step in a wind turbine assembly project is the installation of the wind turbine blades. The three sets of blades are assembled on the ground, and then the assembled blades are lifted as a whole and installed onto the generator set with the help of a large crane.

[0003] A search revealed that Chinese Patent CN207658937U discloses a retractable single-blade hoisting device for wind turbine generators, comprising a cable, a first electric hoist, a left bracket, a support pipe, a lifting lug, a first anti-slip sling, an anti-shear pin, a first support rod, a second support rod, a crossbeam, a second anti-slip sling, a vertical plate, a second electric hoist, an adjusting motor, gears, a rack, and a right bracket. The length is adjustable according to the blade length, and the adjustment is simple. The structure is simple and robust, and easy to manufacture. It can also automatically adjust the horizontality and concentricity of the blades during aerial docking, which facilitates rapid blade installation, greatly improves operational efficiency, and reduces installation risks. However, this solution still has the following shortcomings in practical use:

[0004] When hoisting wind turbine blades, the challenges become particularly pronounced when using the traditional method of assembling three blades into a single unit for hoisting. This is because wind turbines are often located in areas with abundant wind resources and relatively open terrain, which typically experience strong natural winds. During hoisting, the massive, assembled blade assembly suffers even greater wind impact, increasing the difficulty of the hoisting process and significantly amplifying the blades' swaying in the air. This swaying affects the accuracy and safety of the hoisting, and in extreme cases, could lead to accidental collisions between the blades and the tower, resulting in severe economic losses and safety hazards.

[0005] Therefore, it is necessary to design a wind compensation device for the installation site of wind turbine blades to solve the above problems. Summary of the Invention

[0054] As a preferred embodiment of the present invention, the linkage mechanism includes:

[0055] A fixing ring is fixedly installed on the inner side wall of the L-shaped slot;

[0056] A lifting plate is slidably installed on the inner side wall of the L-shaped slot, and the lifting plate is located above the fixing ring;

[0062] The present invention has the following beneficial effects:

[0063] 1. By setting up the mounting hoop and support mechanism, the mounting hoop can be tightly attached to the outer wall of the wind turbine tower and locked with the latch. The outer wall of the guide wheel can always be in contact with the outer wall of the tower. This is beneficial to ensure that the mounting hoop can flexibly adjust the support position according to the change of the outer wall size of the tower during installation and hoisting, thereby achieving stable support for the blade hoisting process and compensating for the impact of wind on the blade hoisting.

[0064] 2. By setting adjustment and connection components, the rotating plate can rotate under the support of spring one as hoisting progresses. It is connected to the rocker plate through a connecting rod. The rotation of the rotating plate drives the connecting rod to move, which in turn pushes the rocker plate to rotate. This facilitates automatic adjustment of the length of the cross adjustment frame, thereby increasing the distance between the bracket and the mounting hoop and reducing the risk of collision between the blade and the tower. When the mounting hoop moves to the predetermined position at the top of the tower, the clamping plate can separate from the slot, releasing the limit between the mounting hoop and the bracket. This makes it easy to disconnect the bracket and the mounting hoop after hoisting is completed, which is convenient for subsequent blade installation work.

[0065] 3. By setting a locking mechanism and a linkage mechanism, the moving plate can slide towards the guide wheel under the action of spring three, thereby locking the guide wheel. This helps ensure that the installation hoop can stay stably in the position when it reaches the top of the tower, preventing it from falling and scratching the outer wall of the tower. By tightening the lifting ring, the moving plate can be separated from the guide wheel, releasing the limit on the guide wheel. This facilitates the easy movement of the installation hoop to the bottom of the tower by hoisting equipment after the blades are installed, allowing for disassembly and reuse.

[0076] 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.

[0077] Reference Figure 1-9A wind power compensation device for wind turbine blade installation site includes two mounting clamps 1; a locking buckle 2, disposed at the opening and closing ends of the two mounting clamps 1; two sets of mounting plates 3, respectively disposed on the inner sidewalls of the two mounting clamps 1, with two mounting plates 3 in each set, and each set of mounting plates 3 is symmetrically fixedly installed on the inner sidewalls of the mounting clamps 1; two sets of support mechanisms, respectively disposed on the two sets of mounting plates 3; two support plates 5, symmetrically fixedly installed on the outer sidewalls of the mounting clamps 1; an adjustment component, disposed between the two support plates 5; a connecting component, disposed between one set of support mechanisms and the adjustment component; two tie rods 8, symmetrically disposed through the outer sidewalls of the mounting clamps 1, the tie rods 8 being slidably connected to the through-holes, and the tie rods 8 being adapted to the support mechanisms; a locking mechanism, disposed on the two tie rods 8; and two L-shaped slots 10, symmetrically disposed on the inner sidewalls of the mounting clamps 1, and the L-shaped slots are... The slot 10 is located directly below the tie rod 8; two sets of linkage mechanisms are respectively set on the inner walls of the two L-shaped slots 10; in use, the two mounting hoops 1 can first be installed on the bottom outer wall of the wind turbine tower and locked with the locking buckle 2. Then, the bracket and the mounting hoop 1 are connected by the adjustment component. During the hoisting process, the mounting hoop 1 moves upward along the tower with the blade. Under the action of the adjustment component and the connecting component, the distance between the bracket and the tower increases, reducing the risk of collision between the two due to strong winds above. After hoisting to the preset position, the mounting hoop 1 and the bracket automatically release the limit, which does not affect the subsequent installation of the blade. At the same time, the support mechanism can lock to prevent the mounting hoop 1 from falling. After installation, the mounting hoop 1 can be moved by the locking mechanism to the bottom of the tower for easy disassembly.

[0078] Reference Figure 6 , Figure 7 The support mechanism includes: four rotating plates 41, rotatably mounted on the upper and lower parts of opposite sides of two mounting plates 3; four mounting slots 42, respectively opened at the ends of the four rotating plates 41 that are far apart from each other; four guide wheels 43, rotatably mounted on the inner sidewalls of the four mounting slots 42, with anti-slip textures on the outer surface of the guide wheels 43; two springs 44, respectively fixedly mounted between opposite ends of the two rotating plates 41; and two connecting rods 45, respectively fixedly mounted between opposite sides of the rotating plates 41 at the same horizontal position, with the connecting rods 45 positioned below the rotation point of the rotating plates 41. The guide wheels 43 on the inner wall of the mounting hoop 1 can fit against the outer surface of the tower. The outer surface size of the tower decreases as it rises. Under the support of the springs 44, the two rotating plates 41 connected to the springs 44 can rotate, ensuring that the outer surface of the guide wheels 43 always fits against the outer surface of the tower. This ensures that the mounting hoop 1 can move vertically upwards as the blades are hoisted, and the rotation of the rotating plates 41 as the mounting hoop 1 moves upwards... Figure 7As shown, the rotating plate 41 on the left can rotate clockwise. Since the connecting rod 45 is located below the rotation point of the rotating plate 41, the rotating plate 41 can drive the connecting rod 45 to move upward during rotation.

[0079] Reference Figure 2 , Figure 3 The adjustment assembly includes: two cross adjustment frames 61, respectively disposed on opposite sides of two support plates 5; two guide openings 62, respectively opened on the sides of the two support plates 5; several guide blocks 64, respectively slidably mounted on the inner sidewalls of the two guide openings 62, and the guide blocks 64 are rotatably connected to the hinges of the cross adjustment frames 61; two springs 63, respectively fixedly mounted on the inner sidewalls of the two guide openings 62, and the other end of the springs 63 is fixedly connected to the side of the guide blocks 64; two sets of snap-fit ​​mechanisms, symmetrically disposed at the ends of the two cross adjustment frames 61 away from the mounting clamp 1; when the ends of the cross adjustment frames 61 are compressed, the overall length can be extended, at which time the guide blocks 64 can slide in the guide openings 62, ensuring the stability of the cross adjustment frames 61. As the cross adjustment frames 61 become longer, the distance between the bracket and the mounting clamp 1 is increased, reducing the risk of blades colliding with the tower due to excessive wind force above.

[0080] Reference Figure 3 The clamping mechanism includes: a connecting plate 65, rotatably mounted on the end of the cross adjustment frame 61 away from the mounting hoop 1; two clamping plates 66, symmetrically fixed on the top surface of the connecting plate 65; and several damping rubber strips 67, respectively arranged in a linear array and fixed on the outer wall of the two clamping plates 66. The bracket for lifting the blade is connected to the mounting hoop 1. The side of the bracket has a slot that matches the clamping plates 66. The four clamping plates 66 at the bottom and top are respectively clamped into the slots on the side of the bracket. After the mounting hoop 1 is connected to the bracket, the blade can be lifted as a whole. After the mounting hoop 1 moves to the predetermined position at the top of the tower, the rotation of the rotating plate 41 reaches its limit. After the ends of the cross adjustment frame 61 away from the mounting hoop 1 approach each other to their limits, the clamping plates 66 on the connecting plate 65 can be separated from the slots on the bracket, releasing the limit between the mounting hoop 1 and the bracket.

[0081] Reference Figure 1 , Figure 2 , Figure 4The connecting assembly includes: two guide frames 71, symmetrically fixedly installed on the outer wall of the mounting hoop 1; two openings 72, respectively opened on the inner side wall of the two guide frames 71, and the openings 72 communicating with the inner side of the mounting hoop 1; four sliders 73, respectively slidably installed on the inner side wall of the two openings 72; four support plates 74, respectively fixedly installed on the sides of the four sliders 73, and the end of the cross adjustment frame 61 is hinged to the side of the support plate 74; two fixing plates 75, respectively fixedly installed on the sides of the upper two sliders 73; a bracket 76, fixedly installed on the inner wall of the mounting hoop 1; and a rotating shaft 77, for rotating the mounting hoop 1. The bracket 76 is mounted on the end away from the mounting clamp 1; two rocker plates 78 are fixedly mounted on both ends of the rotating shaft 77 respectively. The rocker plates 78 are adapted to the connecting rod 45 and the fixed plate 75. The rocker plates 78 are positioned above the connecting rod 45 and the fixed plate 75. When the connecting rod 45 moves upward, it can push the rocker plates 78, so that the rocker plates 78 rotate through the rotating shaft 77 and the bracket 76. When the rocker plates 78 rotate, the end away from the connecting rod 45 can rotate downward and press the fixed plate 75, so that the fixed plate 75 and the slider 73 can slide downward in the through 72, thereby compressing the end of the cross adjustment frame 61.

[0082] Reference Figure 2 , Figure 5 , Figure 6 The locking mechanism includes: two movable plates 91, respectively fixedly installed at the ends of two pull rods 8; a plurality of fixed teeth 92, respectively arranged in a circular array and fixedly installed on the inner sidewalls of the two movable plates 91; a plurality of fixed tooth grooves 93, respectively arranged in a circular array and opened on the outer sidewalls of the two guide wheels 43; a pull plate 94, fixedly installed at the end of the two pull rods 8 away from the movable plates 91; two springs 95, symmetrically fixedly installed between the pull plate 94 and the mounting hoop 1; and a lifting ring 96, fixedly installed on the side of the pull plate 94. After the limit on the pull rods 8 is released by the linkage mechanism, the pull rods 8 and the movable plates 91 can slide towards the guide wheels 43 under the action of the springs 95, and the fixed teeth 92 on the inner wall of the movable plates 91 can engage and enter the guide wheels 43. The guide wheel 43 is in the fixed tooth groove 93 on the outer wall, and the moving plate 91 can squeeze the guide wheel 43 so that the guide wheel 43 can fit tightly against the outer wall of the tower. At the same time, with the cooperation of the fixed teeth 92 and the fixed tooth groove 93, the guide wheel 43 can be locked, so that the installation hoop 1 can stay at the top of the tower, preventing it from falling and scratching the outer wall of the tower. After the blade is installed, the hook of the hoisting equipment can be connected to the lifting ring 96, and the lifting ring 96 can be tightened. As the lifting ring 96 is tightened, the pull plate 94 and the pull rod 8 can slide outward, so that the moving plate 91 separates from the guide wheel 43, releasing the limit on the guide wheel 43. Then, the lifting ring 96 can be pulled down to move the installation hoop 1 to the bottom of the tower, where workers can disassemble it.

[0083] Reference Figure 7 , Figure 8 The linkage mechanism includes: a fixed ring 111, fixedly installed on the inner wall of the L-shaped slot 10; a lifting plate 112, slidably installed on the inner wall of the L-shaped slot 10, with the lifting plate 112 located above the fixed ring 111, and the outer wall of the lifting plate 112 fitting against the inner wall of the L-shaped slot 10; a spring 113, fixedly installed between the fixed ring 111 and the lifting plate 112; a pin block 114, fixedly installed on the top surface of the lifting plate 112; and a pin groove 115, formed on the bottom surface of the pull rod 8, with the pin groove 115 and the pin block 114 fitting together. The cross-sectional shape of the pin block 114 and the pin groove 115 is a right trapezoid; the connecting rope 116 is fixedly installed on the bottom surface of the lifting plate 112, and the end of the connecting rope 116 away from the lifting plate 112 passes through the L-shaped slot 10 and is fixedly connected to the top of the rotating plate 41; during the entire rotation of the rotating plate 41, the lifting plate 112 can be pulled by the connecting rope 116, so that the lifting plate 112 slides down along the L-shaped slot 10, so that the lifting plate 112 descends until the pin block 114 slides out of the pin groove 115, releasing the limit on the pull rod 8.

[0084] The specific working principle of this invention is as follows:

[0085] In use, firstly, the two mounting hoops 1 can be installed on the bottom outer wall of the wind turbine tower and locked with the latch 2. At this time, the guide wheel 43 on the inner wall of the mounting hoist 1 can fit against the outer wall of the tower. Then, the bracket for lifting the blade can be connected to the mounting hoist 1. The side of the bracket has a slot that matches the card plate 66. The four card plates 66 at the bottom and top can be respectively locked into the slots on the side of the bracket. After the mounting hoist 1 is connected to the bracket, the blade can be lifted as a whole. The working principle and connection method of the bracket and the card slot are existing mature technologies and will not be described in detail here.

[0086] As the hoisting progresses, the bracket can move upwards. The outer wall size of the tower decreases as it rises. Supported by spring 44, the two rotating plates 41 connected to spring 44 can rotate, ensuring that the outer wall of the guide wheel 43 remains in contact with the outer wall of the tower. This guarantees that the mounting hoop 1 can move vertically upwards as the blades are hoisted. As the mounting hoop 1 moves upwards, the rotating plates 41 rotate, thus... Figure 7As shown, the left-side rotating plate 41 can rotate clockwise. Since the connecting rod 45 is located below the rotation point of the rotating plate 41, the rotating plate 41 can drive the connecting rod 45 to move upward during rotation. The upward movement of the connecting rod 45 can push the rocker plate 78, causing the rocker plate 78 to rotate with the bracket 76 via the rotating shaft 77. During the rotation of the rocker plate 78, the end away from the connecting rod 45 can rotate downward and press the fixed plate 75, allowing the fixed plate 75 and the slider 73 to slide downward in the opening 72. This compresses the end of the cross adjustment frame 61, making the overall length longer. At this time, the guide block 64 can slide in the guide opening 62, ensuring the stability of the cross adjustment frame 61. As the cross adjustment frame 61 becomes longer, the distance between the bracket and the mounting hoop 1 is increased, reducing the risk of the blade colliding with the tower due to excessive wind force above.

[0087] As the hoisting progresses, once the installation hoist 1 has moved to its predetermined position at the top of the tower, the rotation of the rotating plate 41 reaches its limit, and the pressure on the rocker plate 78 also reaches its limit. When the ends of the cross-adjusting brackets 61 furthest from the installation hoist 1 approach each other to their limits, the locking plate 66 on the connecting plate 65 can separate from the locking groove on the bracket, releasing the limiting relationship between the installation hoist 1 and the bracket. Furthermore, during the entire rotation of the rotating plate 41, the lifting plate 112 can be pulled by the connecting rope 116, causing the lifting plate 112 to slide downwards along the L-shaped slot 10. Once the lifting plate 112 descends to the pin... When block 114 slides out of pin groove 115, under the action of spring 3 95, pull rod 8 and moving plate 91 can slide towards guide wheel 43. The fixing teeth 92 on the inner wall of moving plate 91 can engage into the fixing tooth groove 93 on the outer wall of guide wheel 43, and moving plate 91 can squeeze guide wheel 43, so that guide wheel 43 can fit tightly against the outer wall of tower. At the same time, with the cooperation of fixing teeth 92 and fixing tooth groove 93, guide wheel 43 can be locked, so that mounting hoop 1 can stay at the top of tower, preventing it from falling and scratching the outer wall of tower.

[0088] After the blades are installed, the hook of the hoisting equipment can be connected to the lifting ring 96, and the lifting ring 96 can be tightened. As the lifting ring 96 is tightened, the pull plate 94 and the pull rod 8 can slide outward, so that the moving plate 91 is separated from the guide wheel 43, releasing the limit on the guide wheel 43. Then, the lifting ring 96 can be pulled down to move the installation hoop 1 to the bottom of the tower, where workers can disassemble it. Throughout the process, the use of the cross adjustment frame 61 and the installation hoop 1 ensures that the support used for hoisting is supported and fixed during the hoisting process, thereby compensating for wind force during hoisting and minimizing the impact of wind force on hoisting.
