DETAILED DESCRIPTION

[0081] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings.

The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application.

[0082] In the description of the present application, it should be understood that the terms "counterclockwise", "clockwise", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0083] Wind power converts wind energy into electrical energy. Generally, as the length and weight of the wind turbine blades increase, its power generation capacity will also increase. The installation of wind turbine units is usually carried out by hoisting the wind turbine blades to the target height and position, and then firmly installing the wind turbine blades on the wind power piles.

[0084] Due to the complex and changeable offshore environment, during the process of lifting the blades, the lifting equipment lifts the blades from position A and moves them to position B to install the blades. During this process, large shaking is likely to occur, and the blades are not easy to align with the installation interface, which can easily lead to safety accidents such as blades falling off.

[0085] The embodiment of the present application provides a wind turbine blade hoist based on an offshore wind turbine unit, which aims to solve the technical problems of low docking accuracy, easy shaking during hoisting, and safety accidents in the existing blade hoist. The present application controls the distance between multiple clamping bases in the clamping assembly through an adjustment component, so that the clamping base clamps wind turbine blades of different lengths. After reaching the specified height, the adjustment component is used to control the multiple clamping bases to move in the same direction to the specified position to avoid shaking and causing safety accidents.

[0086] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0087] Figure 1 A schematic diagram of the structure of a wind turbine blade hanger based on an offshore wind turbine unit is provided for this application. Figure 1As shown in the figure, the wind turbine blade sling includes a clamping assembly 200 and an adjusting assembly 300; the clamping assembly 200 includes a clamping box 210 and a plurality of clamping base members. A fixing plate 214 is arranged in the clamping box 210, and the plurality of clamping base members are respectively and independently arranged on both sides of the clamping box 210; the clamping base members penetrate through the side wall of the clamping box 210 and extend into the clamping box 210, and are detachably connected to the adjusting assembly 300 arranged in the clamping box 210; the clamping base members are used for clamping the wind turbine blade, and the adjusting assembly 300 can control the plurality of clamping base members to freely move on the clamping box 210 in the same or opposite directions.

[0088] The clamping assembly 200 is used to clamp the wind turbine blade, so that the sling can lift the wind turbine blade to the target height and position and then install it. The clamping assembly 200 can clamp wind turbine blades of different lengths. For example, a plurality of clips with different spacings can be arranged on the clamping assembly 200, and the spacing between every two clips can be equal or unequal to cope with wind turbine blades of different lengths; two clips can also be movably arranged on the clamping assembly 200, and the spacing between the two racks can be freely adjusted according to wind turbine blades of different lengths.

[0089] The clip openings of the clips for clamping the wind turbine blade arranged on the clamping assembly 200 can be movable or fixed. For example, the clip openings of the clips can be movable, and the size of the clip openings can be adjusted when clamping wind turbine blades of different thicknesses; the clip openings of the clips can also be fixed. In one embodiment, the clip openings can be set in an "匸" shape, and the spacing opening between the upper and lower clamping arms of the clip is fixed. Since the wind turbine blade has a certain width, the wind turbine blade can be clamped in the clip opening. Of course, the specific structure of the clips for clamping the wind turbine blade on the clamping assembly 200 includes, but is not limited to, the above examples, and those that can horizontally clamp the wind turbine blade are all included in the inventive concept of the present application.

[0090] The plurality of clamping base members on the clamping assembly 200 are movably arranged on both sides of the clamping box 210. The above-mentioned clips can be detachably connected to the clamping base members by welding, bonding or other methods, or by inserting pins, clamping or other methods, and the clips can move freely together with the clamping base members. A fixing plate 214 is arranged on the clamping box 210, and the fixing plate 214 is arranged above the clamping base members.

[0091] The adjustment component 300 can control the adjustment clamping component 200 to move freely horizontally by means of electric control, hydraulic control, electromagnetic control or elastic principle control, and can also control the multiple clamps in the adjustment clamping component 200 to move in the same direction or different directions in the horizontal direction. For example, on the ground, in order to cope with wind turbine blades of different lengths, the adjustment component 300 controls the multiple clamps on the clamping component 200 to move in opposite directions, clamp the wind turbine blades, and use the steel cables on the sling to lift the sling and the wind turbine blades to a specified height. When the wind turbine blades are moved horizontally to a specified position, when the sling and the wind turbine blades are moved horizontally by the steel cables, a large shaking will occur on the sea surface, which is prone to safety accidents such as falling. Therefore, in this embodiment, the adjustment component 300 controls the multiple clamps on the clamping component 200 to move to the specified position in the same direction, which can well avoid shaking.

[0092] like Figure 5 As shown, the adjustment component 300 includes a conveying member 310, a hydraulic barrel 320 and a fixed barrel 330. The conveying member 310 is arranged at the bottom end of the fixed plate 214, and the two sides of the conveying member 310 are detachably connected to multiple clamping base members; the fixed barrel 330 passes through the top of the fixed plate 214 and extends to the bottom end of the conveying member 310, the hydraulic barrel 320 is sleeved in the fixed barrel 330, and the fixed barrel 330 and the conveying member 310 are connected, and the clamping base members can move freely through hydraulic control.

[0093] The conveying member 310 is arranged under the fixed plate 214 and is connected to multiple clamping base members for controlling the free movement of the clamping base members in the horizontal direction. One, two or more clamping base members can be connected to the conveying member 310 by welding, bonding, or detachable means such as snap-on, latching, etc. The clamping base members clamp the fan blades, and multiple clamping base members can move in opposite or same directions.

[0094] The fixed barrel 330 is arranged on the top of the fixed plate 214, and penetrates from the top of the fixed plate 214 and extends to the bottom of the conveying member 310. The hydraulic barrel 320 is sleeved in the fixed barrel 330. The fixed barrel 330 and the conveying member 310 are connected. The hydraulic barrel 320 inputs hydraulic oil into the fixed barrel 300, and the hydraulic oil in the fixed barrel 300 is input into the conveying member 310. The different delivery paths of the hydraulic oil are used to control the free movement of the clamping base members in opposite or same directions.

[0095] In the specific implementation process, Fig. 9As shown, multiple steel cables 12 are connected between the crane base 11 and the hoist. The hoist clamps the fan blades 10 of different lengths by adjusting the distance between the two clamping bases. Then, the crane base 11 hoists the hoist and the fan blades 10 to a specified height. In order to avoid swinging during the lifting process, a steel cable 12 is provided to connect one end of the fan blade 10 and the crane base 11. After reaching the specified height, the hoist controls the two clamping bases to move in the same direction to the specified position to install the fan blade 10.

[0096] The embodiment of the present application provides a wind turbine blade hanger based on an offshore wind turbine unit, which is provided with a clamping assembly and an adjusting assembly; the clamping assembly includes a clamping box and a plurality of clamping base members, a fixing plate is provided in the clamping box, and the plurality of clamping base members are independently arranged on both sides of the clamping box; the clamping base members penetrate from the side wall of the clamping box and extend into the clamping box, and are detachably connected to the adjusting assembly arranged in the clamping box; the clamping base members are used to clamp the wind turbine blades, and the adjusting assembly can control the plurality of clamping base members to move freely on the clamping box in the same or opposite directions; the adjusting assembly includes a conveying member, a hydraulic barrel and a fixed barrel, the conveying member is provided at the bottom end of the fixed plate, and the two sides of the conveying member are detachably connected to the plurality of clamping base members respectively; the fixed barrel penetrates from the top end of the fixed plate and extends to the bottom end of the conveying member, the hydraulic barrel is sleeved in the fixed barrel, the fixed barrel and the conveying member are communicated, and the clamping base members are freely moved by hydraulic control.

At the same time, it can effectively control the docking accuracy and improve the efficiency and safety performance of the fan blade installation.

[0097] Further, based on the above embodiments, the clamping base is described in more detail, such as Figure 2 and Figure 3 As shown, the clamping base includes a first clamping arm 220 and a second clamping arm 230 of the same structure, and a first clamping member 221 and a second clamping member 231 of the same structure; a T-slot 213 is provided on the side wall of the clamping box 210 located at the lower end of the fixed plate 214, and one end of the first clamping arm 220 passes through the T-slot 213 and is movably connected and communicated with the conveying member 310; a first clamping member 221 is fixedly provided at the bottom end of the other end of the first clamping arm 220; the first clamping member 221 has a clamping groove parallel to the clamping box 210, and the clamping groove is used to clamp the fan blades.

[0098] The first clamping arm 220 and the second clamping arm 230 have the same structure. They respectively pass through the T-shaped grooves 213 under the fixed plate 214 from both sides of the clamping box 210, and are detachably connected to the conveying member 310 by means such as bolts and clamping, and can slide freely in the T-shaped grooves 213. The first clamping arm 220 and the second clamping arm 230 are not only the same in structure, but also cooperate with each other functionally to ensure the stability and reliability of the clamping process. On the first clamping arm 220 and the second clamping arm 230, there are also connected with the first clamping member 221 and the second clamping member 231 with the same structure by means such as welding and bonding. Both the first clamping member 221 and the second clamping member 231 are provided with clamping grooves for clamping the fan blade. The clamping groove can be set in a "匸" shape to ensure the stability and safety of the blade during the clamping process. In addition, the design of the clamping groove also takes into account the shape and size of the blade, so as to provide the best support and fixing effect during the clamping process, thereby improving the accuracy and efficiency of the overall operation.

[0099] Further, as Figure 4 shown, on both sides of the conveying member 310, there are respectively provided with a plurality of telescopic rods 240 and a plurality of hydraulic pipes 250; one ends of the plurality of telescopic rods 240 are respectively and independently fixedly connected to the side edges on both sides of the conveying member 310, and the other ends of the plurality of telescopic rods 240 are sleeved on the first clamping arm 220; the plurality of hydraulic pipes 250 communicate the conveying member 310 and the first clamping arm 220, and the hydraulic pipes 250 are communicated with the fixed barrel 330.

[0100] Between the conveying member 310 and the first clamping arm 220, and between the conveying member 310 and the second clamping arm 230, there are respectively provided with a plurality of telescopic rods 240 to ensure that the first clamping arm 220 and the second clamping arm 230 can slide freely in a direction parallel to the fixed plate 214. In addition, between the conveying member 310 and the first clamping arm 220, and between the conveying member 310 and the second clamping arm 230, there are also arranged a plurality of hydraulic pipes 250, so that the first clamping arm 220, the second clamping arm 230 are communicated with the conveying member 310 and the fixed barrel 330. By setting different hydraulic oil conveying paths in the first clamping arm 220 and the second clamping arm 230, precise control of the hydraulic oil can be achieved, thereby adjusting the movement directions of the first clamping arm 220 and the second clamping arm 230. Specifically, by inputting hydraulic oil into the first clamping arm 220 and the second clamping arm 230, under the control of different paths, the first clamping arm 220 and the second clamping arm 230 can move in the same direction or in opposite directions, improving the flexibility and controllability of the system.

[0101] Further, as Figure 5As shown, a storage space is provided in the fixed barrel 330, and a plurality of connecting pipes 334 are connected to the outer side wall of the fixed barrel 330, and the connection 334 is connected to the storage space; the connecting pipe 334 is connected to the conveying member 310 and the hydraulic pipeline 250; the hydraulic barrel 320 is sleeved in the storage space, and the hydraulic barrel 320 can move freely up and down in the storage space.

[0102] A cylindrical accommodation space is provided in the fixed barrel 330, and a plurality of connecting pipes 334 are connected to the outer wall of the fixed barrel 330, and the connecting pipes 334 are connected to the accommodation space, and the connecting pipes 334 are connected to the conveying member 310 and the hydraulic pipeline. A hydraulic barrel 320 is sleeved in the accommodation space, and the hydraulic barrel can slide freely up and down in the accommodation space, so that the hydraulic oil input into the accommodation space is conveyed to the plurality of connecting pipes 334 and the conveying member 310.

[0103] Further, such as Figure 6 As shown, a baffle base 331 is also provided in the accommodating space, and the baffle base 331 is fixedly connected or detachably connected to the inner wall of the accommodating space; a hydraulic channel is provided at the bottom end of the hydraulic barrel 320, and when the hydraulic barrel 320 is sleeved in the accommodating space, the baffle base 331 is inserted into the hydraulic channel.

[0104] A shield base 331 is also provided in the accommodation space, and the shield base 331 can be fixedly connected to the inner side wall of the accommodation space in a variety of ways, such as permanent connection methods such as welding and bonding, or detachable connection methods such as bolts, clamping, and latches, so as to facilitate maintenance and replacement. A hydraulic channel is provided at the bottom end of the hydraulic barrel 320. When the hydraulic barrel 320 is sleeved in the accommodation space, the shield base 331 will be sleeved into the hydraulic channel, thereby realizing the sealing and functional connection of the hydraulic system. In order to ensure that the hydraulic barrel 320 can be smoothly sleeved in the accommodation space, the size of the hydraulic barrel 320 and the size of the accommodation space are precisely designed to match each other, thereby ensuring the stability and reliability of the hydraulic system, facilitating the installation and removal of the hydraulic barrel 320, and improving the maintenance efficiency and operation convenience of the system. In this way, a tight connection is formed between the hydraulic barrel 320 and the accommodation space, ensuring that the hydraulic oil can be effectively transmitted in the system.

[0105] Further, such as Figure 6 and Figure 8 As shown, a plurality of slide grooves 333 are provided on the inner wall of the accommodation space, and a plurality of sliders 323 are correspondingly provided on the outer wall of the hydraulic barrel 320; when the hydraulic barrel 320 rotates and moves in the accommodation space, the sliders 323 slide freely in the slide grooves 333; the slide grooves 333 form a slope along the inner wall of the accommodation space, so that when the hydraulic barrel 320 moves to the bottom of the accommodation space, the sliders 323 are temporarily fixed in the slide grooves 333.

[0106] A plurality of identical or different slide grooves 333 are arranged on the inner side wall of the accommodation space, and the design of the slide grooves 333 can be adjusted according to specific application requirements to adapt to different operating conditions and functional requirements. Accordingly, a plurality of sliders 323 are arranged on the outer side wall of the hydraulic barrel 320, and these sliders 323 cooperate with the slide grooves 333. When the hydraulic barrel 320 rotates or moves in the accommodation space, the sliders 323 can slide freely along the slide grooves 333, thereby realizing the smooth movement and positioning of the hydraulic barrel 320.

[0107] A slope of the slide groove 333 is designed near the bottom of the accommodation space so that the slider 323 can be temporarily fixed in the slide groove 333 when the hydraulic barrel 320 slides to the bottom of the accommodation space, which can ensure the stability of the hydraulic barrel 320 in the working position. The hydraulic pressure or the delivery path of the hydraulic oil in the accommodation space can be adjusted by controlling the fixed state of the slider 323, so as to achieve precise control of the first clamping arm 220 and the second clamping arm 230 so that they can move in the same direction or in opposite directions. For example, when the first clamping arm 220 and the second clamping arm 230 need to move in the same direction, the position of the hydraulic barrel 320 can be adjusted so that the slider 323 is fixed in the slide groove 333, thereby changing the delivery path of the hydraulic oil and ensuring that the hydraulic oil can be evenly distributed to the two clamping arms. Conversely, when the first clamping arm 220 and the second clamping arm 230 need to move in opposite directions, similar adjustments can be made so that the hydraulic oil is delivered to the two clamping arms respectively, thereby achieving the effect of moving in opposite directions.

[0108] Further, such as Figure 6 As shown, a plurality of elastic members 324 are provided at the bottom end of the hydraulic barrel 320; a plurality of through holes 322 are also provided on the hydraulic barrel 320, and the through holes 322 are perpendicular to and connected with the hydraulic channels; a lifting member 321 is also provided at the top end of the hydraulic barrel 320, and the lifting member 321 is used to enable the hydraulic barrel 320 to slide freely up and down in the accommodating space of the fixed barrel 330; the height of the hydraulic barrel 320 is greater than the depth of the accommodating space, and the diameter of the hydraulic barrel 320 matches the diameter of the accommodating space.

[0109] The bottom of the hydraulic barrel 320 is provided with a plurality of elastic members 324, which are designed to provide additional buffering and stability to ensure that the hydraulic barrel 320 can effectively absorb vibration and impact during operation. At the same time, when the hydraulic barrel 320 moves to the bottom of the fixed barrel 310, the upward elastic force of the elastic member 324 makes the slider 323 more firmly stuck in the slot 333; when the hydraulic barrel 320 is to be moved upward, the elastic member 324 provides an elastic force to enable the hydraulic barrel to move upward faster. The hydraulic barrel 320 is also provided with a plurality of through holes 322, which are perpendicular to and connected to the hydraulic channel, to ensure that the hydraulic oil can flow freely between the inside and outside of the hydraulic barrel 320, and realize the efficient operation of the hydraulic system.

[0110] The top of the hydraulic barrel 320 is also provided with a lifting member 321, which is designed to facilitate the operator to easily lift the hydraulic barrel 320 when needed, so that it can slide freely up and down in the accommodation space of the fixed barrel 330. The provision of the lifting member 321 improves the convenience of operation of the hydraulic barrel 320 and enhances its flexibility during maintenance and replacement. The bottom of the fixed barrel 330 is provided with a channel, which is connected to the channel provided on the connecting pipe 334 to form a complete hydraulic oil transmission path. When the hydraulic oil is input into the fixed barrel 330, the hydraulic oil can be effectively transported to various parts of the system through the channel and the connecting pipe 334, thereby realizing precise control of the first clamping arm 220 and the second clamping arm 230. By transporting the hydraulic oil, the moving directions of the first clamping arm 220 and the second clamping arm 230 can be controlled respectively, so that they can move in the same direction or in opposite directions according to specific needs.

[0111] Further, such as Figure 7 As shown, the baffle base 331 includes a plurality of baffles 332 and a baffle frame 3311; the baffle frame 3311 is connected to the inner wall of the accommodating space, and a plurality of circular plates 3321 are arranged on the top of the baffle frame 3311, and the size of the circular plates 3321 matches the through hole 322; a circular convex plate 3322 is arranged on the bottom of the baffle frame 3311, and the size of the circular convex plate 3322 matches the hydraulic channel; when the hydraulic barrel 320 moves upward in the accommodating space, the baffle 332 blocks the through hole 322, and the first clamping arm 220 and the second clamping arm 230 are adjusted to move toward each other; when the hydraulic barrel 320 moves downward in the accommodating space, the circular convex plate 3322 blocks the hydraulic channel, and the first clamping arm 20 and the second clamping arm 230 are adjusted to move in the same direction.

[0112] The plurality of shields 332 on the shield base 331 are connected by a shield frame 3311, and the shield frame 3311 is fixedly connected to the inner wall of the accommodation space. The top of the shield frame 3311 is provided with a plurality of circular plates 3321, the size of which is precisely designed to match the through hole 322 on the hydraulic barrel 320, thereby ensuring that the through hole 322 can be effectively blocked under certain conditions. The bottom of the shield frame 3311 is provided with a circular convex plate 3322, the size of which is also precisely designed to match the hydraulic channel, thereby ensuring that the hydraulic channel can be effectively blocked when needed.

[0113] When the hydraulic barrel 320 moves upward in the accommodation space, the shield 332 will gradually approach and eventually block the through hole 322, thereby changing the flow path of the hydraulic oil, thereby adjusting the movement of the first clamping arm 220 and the second clamping arm 230. Specifically, when the through hole 322 is blocked by the shield 332, the hydraulic oil will be forced to flow through other preset paths, thereby achieving the control of the two clamping arms towards each other, accurately controlling the movement direction of the clamping arms, and quickly adjusting the working state of the system when necessary to adapt to different operating requirements.

[0114] On the contrary, when the hydraulic barrel 320 moves downward in the accommodation space, the circular convex plate 3322 will gradually approach and eventually block the hydraulic channel, which will also change the flow path of the hydraulic oil, thereby adjusting the same-direction movement of the first clamping arm 220 and the second clamping arm 230. When the hydraulic channel is blocked by the circular convex plate 3322, the hydraulic oil will flow through another preset path, thereby achieving the same-direction control of the two clamping arms, which can ensure the efficient operation of the system and provide flexible operation options under different working conditions.

[0115] Further, such as Figure 2 As shown, a sliding member 260 is fixedly provided at the top end of the first clamping arm 220, and a corresponding fixed plate 214 is provided with a strip groove 212; the sliding member 260 is clamped in the strip groove 212, and when the first clamping arm 220 moves freely, the sliding member 260 slides freely in the strip groove 212; the maximum or minimum distance of movement of the first clamping arm 220 is controlled by the sliding member 260 and the strip groove 212.

[0116] In order to ensure that the first clamping arm 220 and the second clamping arm 230 can be effectively controlled when they slide freely in the clamping box 210, and to avoid excessive movement distance, which may cause excessive force on the system or damage the sling, a precise sliding control mechanism is designed. Sliders 260 are fixedly arranged at the top of the first clamping arm 220 and the second clamping arm 230, respectively. The design of the sliders 260 provides additional stability and control force, so that the clamping arms can remain stable and controlled during the movement. Correspondingly, a strip groove 212 is arranged on the fixed plate 214. The length and position of the strip groove 212 are designed to ensure that a sufficient sliding range can be provided while limiting the maximum and minimum moving distances of the clamping arms. The slide 260 is clamped in the strip groove 212. When the first clamping arm 220 and the second clamping arm 230 move freely in the clamping box 210, the slide 260 can slide freely in the strip groove 212, thereby realizing precise control of the moving distance of the clamping arms. A highly integrated sliding control system is formed between the sliding member 260 and the strip groove 212. When the first clamping arm 220 and the second clamping arm 230 move in the clamping box 210, the sliding member 260 slides in the strip groove 212, thereby limiting the maximum and minimum moving distances of the clamping arms, preventing the clamping arms from moving too far and causing excessive force on the sling, and ensuring that the clamping arms are always kept in a safe and controlled range during the working process, thereby improving the overall stability and reliability of the sling.

[0117] Further, such as Figure 1 and Figure 3 As shown, the wind turbine blade hanger also includes a control platform 100, which is connected to the outside of the clamping box 210 and communicated with the adjustment component 300; hydraulic oil is input into the adjustment component 300 through the control platform 100 to control the free movement of the clamping base; the control platform 100 includes a connecting arm 110 and an infusion tube 120, the connecting arm is connected to the clamping box 210, and the infusion tube 120 passes through the clamping box 210 and communicates with the adjustment component 300.

[0118] The control platform 100 on the wind turbine blade hanger is connected to the outside of the clamping box 210 and is in communication with the adjustment assembly 300. Hydraulic oil is input into the adjustment assembly 300 through the control platform 100 to achieve free movement and precise control of the clamping base. The control platform 100 provides a convenient and efficient operation interface, allowing operators to easily adjust various parameters of the hanger, thereby ensuring the stability and reliability of the wind turbine blade hanger.

[0119] The connecting arm 110 in the control platform 100 is firmly connected to the clamping box 210, providing a stable support structure so that the control platform 100 can be firmly fixed in the system. The connecting arm 110 has certain strength and stability, and also takes into account the convenience of installation and maintenance.

[0120] The infusion pipe 120 in the control platform 100 passes through the clamping box 210 and is connected to the adjustment component 300 to form a complete hydraulic oil transmission path. Through the infusion pipe 120, the hydraulic oil can be smoothly transported from the control platform 100 to the adjustment component 300, thereby achieving precise control of the system. The infusion pipe 120 is usually made of materials with high strength, corrosion resistance and high pressure resistance to ensure its long-term operation in complex working environments.

[0121] In actual operation, the control platform 100 enables the operator to easily input hydraulic oil into the adjustment assembly 300 through the synergistic effect of the connecting arm 110 and the infusion tube 120, thereby controlling the free movement of the clamping base member, thereby improving the convenience of operation of the sling. The operator can accurately adjust the position and angle of the clamping base member through the control platform 100, thereby ensuring the stability and safety of the fan blade.
