Description

Technical Field

[0001] This utility model relates to the field of wind turbine blade support technology, and in particular to a fixed support for transporting offshore wind turbine blades. Background Technology

[0002] Wind turbine blades are a core component of offshore wind turbines, and their design and manufacturing directly affect the power generation efficiency and overall performance of wind farms. These blades are made of lightweight, high-strength materials, such as fiberglass and carbon fiber composites. These materials not only ensure the strength and rigidity of the blades but also reduce their weight, enabling the wind turbines to start and operate effectively at lower wind speeds.

[0003] Due to their large size and unique shape, wind turbine blades are susceptible to wind, vibration, and external impacts during transportation. Fixed supports are typically used to limit and protect the blades, preventing tilting, collisions, or deformation during transport, thus reducing the risk of damage. Current wind turbine blade transport protection supports use rectangular frames to secure both ends of the blade. During transport, the rectangular frame is hoisted onto the ship along with the blade, and then the frame is used to secure the blade.

[0004] However, due to the different specifications and dimensions of wind turbine blades, the required rectangular frame dimensions are also different. The bracket base cannot be adapted to rectangular frames of different sizes for effective fixing, resulting in poor fixation versatility. Utility Model Content

[0005] The technical problem to be solved by this utility model is that the required rectangular frame size is also different due to the different specifications and dimensions of wind turbine blades. The support base cannot be adapted to rectangular frames of different sizes for effective fixing, resulting in poor fixation versatility.

[0006] To solve the above-mentioned technical problems, this utility model provides a technical solution for a transport and fixing support for offshore wind turbine blades: The offshore wind turbine blade transport and fixing support includes a rectangular frame and a base structure. The rectangular frame has an internal space for the wind turbine blade to pass through, and the rectangular frame can be detachably installed on the base structure. The base structure includes a base body, a first bidirectional lead screw, and two first clamping blocks. The base body has a first sliding groove along its length. The two first clamping blocks are movably installed in the first sliding groove, and the first bidirectional lead screw is rotatably installed in the first sliding groove. Two first clamping blocks are symmetrically distributed on the first bidirectional lead screw and threadedly connected to the first bidirectional lead screw. The threads of the first bidirectional lead screw corresponding to the two first clamping blocks have opposite directions. The two first clamping blocks are clamped to the rectangular frame along the length direction. The upper part of the two first clamping blocks is provided with through grooves, which extend along the height direction of the base body. A pressure plate is adjustablely installed in the through groove. The pressure plate protrudes towards the other first clamping block and is pressed tightly against the bottom of the rectangular frame.

[0007] Furthermore, an adjusting screw is rotatably installed in the through groove. The axis of the adjusting screw extends along the height direction of the base body. The adjusting screw is threadedly connected to the pressure plate. An adjusting handwheel is installed on the upper side of the first clamping block. The adjusting handwheel is connected to the adjusting screw to prevent rotation.

[0008] Furthermore, the base structure also includes a second bidirectional lead screw and two second clamping blocks. The base body has a second sliding groove along the width direction. The second sliding groove communicates with the first sliding groove. The two second clamping blocks are movably installed in the second sliding groove. The second bidirectional lead screw is rotatably installed in the second sliding groove. Two second clamping blocks are symmetrically distributed on the second bidirectional lead screw and threadedly connected to the second bidirectional lead screw. The threads of the second bidirectional lead screw have opposite directions to the two second clamping blocks. The two second clamping blocks are clamped to the rectangular frame along the width direction.

[0009] Furthermore, the depth of the second groove is less than the depth of the first groove, and the second bidirectional lead screw and the first bidirectional lead screw are arranged vertically at intervals.

[0010] Furthermore, the second bidirectional lead screw and the two second clamping blocks form a front and rear clamping structure. There are two front and rear clamping structures, which are arranged symmetrically about the center of the first slide groove.

[0011] Furthermore, a second rocker arm is installed on the side of the base body corresponding to the width direction. The second rocker arm is connected to a second bidirectional lead screw to prevent rotation. A gear is fixed in the middle of each of the two second bidirectional lead screws, and a synchronous belt is connected between the two gears.

[0012] Furthermore, a first rocker arm is installed on the side of the base body corresponding to the length direction. The first rocker arm is connected to the first bidirectional lead screw to prevent rotation. A handle is installed at the eccentric position of the first rocker arm. The handle is movable along the axis parallel to the first bidirectional lead screw. The base body is also provided with a limiting hole facing the first rocker arm. The handle is inserted into the limiting hole.

[0013] Furthermore, multiple limiting holes are provided, and the multiple limiting holes are axially spaced from the rotational contour of the first rocker handle. A return spring is also provided between the handle and the first rocker handle.

[0014] Furthermore, the first clamping block has first protruding ribs on both sides, and the first guide groove has first guide grooves on both sides of the first sliding groove. The first protruding ribs and the first guide grooves are guided and engaged along the length direction of the base body. The second clamping block has second protruding ribs on both sides, and the second guide groove has second guide grooves on both sides of the second sliding groove. The second protruding ribs and the second guide grooves are guided and engaged along the width direction of the base body.

[0015] Compared with existing technologies, the offshore wind turbine blade transport and fixing support of this utility model has the following advantages: The support adopts a rectangular frame and base structure design. The rectangular frame provides space for the wind turbine blade to pass through and be fixed in place. The rectangular frame can be detachably installed on the base structure, which provides a foundation for transport and installation, ensuring the wind turbine blade remains stably fixed during transport. The base structure includes a base body, a first bidirectional lead screw, and two first clamping blocks. The base body has a first sliding groove along its length, and the first bidirectional lead screw is housed within the first sliding groove. The two first clamping blocks are symmetrically installed on both sides of the first bidirectional lead screw with opposite thread directions.

[0016] In use, rotating the first bidirectional lead screw allows for simultaneous reverse adjustment of the two first clamping blocks. The two first clamping blocks retract or expand their distance along the first sliding groove to accommodate rectangular frames of different lengths. The threaded engagement design between the first bidirectional lead screw and the two first clamping blocks allows for stepless adjustment of the clamping distance. The threaded drive of the lead screw generates reliable clamping force and possesses anti-loosening and self-locking characteristics, preventing the risk of loosening due to transportation vibrations.

[0017] In addition, the upper part of the two first clamping blocks is provided with through slots that extend along the height direction of the base body. Pressure plates are adjustablely installed within these slots, and pressure rods protrude towards the other first clamping block. The pressure plates of the two first clamping blocks vertically press the bottom sides of the rectangular frame, preventing warping or wobbling. Furthermore, by adjusting the height of the pressure plates, different cross-sectional thicknesses at the bottom of the rectangular frame can be accommodated, meeting the fixing requirements of rectangular frames of different sizes and improving the versatility of the base structure.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0023] like Figures 1 to 6 As shown in the figure, an embodiment of the present invention provides a transport and fixing support for offshore wind turbine blades, including a rectangular frame 1 and a base structure 2. The rectangular frame 1 has an internal space for the wind turbine blades 3 to pass through, and the rectangular frame 1 is detachably mounted on the base structure 2. The base structure 2 includes a base body 20, a first bidirectional lead screw 21, and two first clamping blocks 22. The base body 20 has a first sliding groove 201 along its length, and the two first clamping blocks 22 are movably mounted in the first sliding groove 201. The first bidirectional lead screw 21 is rotatably mounted in the first sliding groove 201.

[0024] Two first clamping blocks 22 are symmetrically distributed on the first bidirectional lead screw 21 and threadedly connected to the first bidirectional lead screw 21. The threads of the first bidirectional lead screw 21 are opposite to those of the two first clamping blocks 22. The two first clamping blocks 22 are clamped to the rectangular frame 1 along the length direction. A through groove 220 is provided on the upper part of the two first clamping blocks 22. The through groove 220 extends along the height direction of the base body 20. A pressure plate 221 is adjustablely installed in the through groove 220. The pressure plate 221 protrudes towards the other first clamping block 22. The pressure plate 221 is clamped to the bottom of the rectangular frame 1.

[0025] The offshore wind turbine blade 3 transport and fixing support adopts a design of rectangular frame 1 and base structure 2. The rectangular frame 1 has a space for the wind turbine blade 3 to pass through and be fixed and limited. The rectangular frame 1 can be detachably installed on the base structure 2. The base structure 2 has fixing holes 200 for bolts to pass through, so that the base structure 2 can be fixed on the transport ship or vehicle. The base structure 2 provides a transport and installation foundation for the rectangular frame 1, ensuring that the wind turbine blade 3 remains stably fixed during transportation. The base structure 2 includes a base body 20, a first bidirectional lead screw 21, and two first clamping blocks 22. The base body 20 has a first sliding groove 201 along its length. The first bidirectional lead screw 21 is built into the first sliding groove 201. The two first clamping blocks 22 are symmetrically installed on both sides of the first bidirectional lead screw 21 with opposite thread directions.

[0026] In use, rotating the first bidirectional lead screw 21 allows for simultaneous reverse adjustment of the two first clamping blocks 22. The two first clamping blocks 22 contract or expand their spacing along the first slide groove 201 to accommodate rectangular frames 1 of different lengths. The threaded engagement design between the first bidirectional lead screw 21 and the two first clamping blocks 22 allows for stepless adjustment of the clamping distance. The threaded drive of the lead screw generates reliable clamping force and possesses anti-loosening and self-locking characteristics, preventing the risk of loosening due to transportation vibrations.

[0027] In addition, the upper part of the two first clamping blocks 22 is provided with through grooves 220, which extend along the height direction of the base body 20. Pressure plates 221 are adjustablely installed in the through grooves 220, and pressure rods protrude towards the other first clamping block 22. The pressure plates 221 of the two first clamping blocks 22 are used to vertically press the bottom sides of the rectangular frame 1, preventing the rectangular frame 1 from warping or shaking. Moreover, by adjusting the height of the pressure plates 221, it can adapt to different cross-sectional thicknesses at the bottom of the rectangular frame 1, meeting the fixing requirements of rectangular frames 1 of different sizes and improving the fixing versatility of the base structure 2.

[0028] In this embodiment, an adjusting screw 222 is rotatably installed in the through groove 220. The axis of the adjusting screw 222 extends along the height direction of the base body 20. The adjusting screw 222 is threadedly connected to the pressure plate 221. An adjusting handwheel 223 is installed on the upper side of the first clamping block 22, and the adjusting handwheel 223 is connected to the adjusting screw 222 to prevent rotation. The adjusting handwheel 223 drives the adjusting screw 222 to rotate, and drives the pressure plate 221 to slide and adjust its height in the through groove 220. The screw thread transmission enables the pressure plate 221 to generate a reliable clamping force on the bottom of the rectangular frame 1 and meet the anti-loosening and self-locking requirements.

[0029] As a further preferred embodiment, the base structure 2 also includes a second bidirectional lead screw 23 and two second clamping blocks 24. The base body 20 has a second sliding groove 202 along the width direction. The second sliding groove 202 communicates with the first sliding groove 201. The two second clamping blocks 24 are movably installed in the second sliding groove 202. The second bidirectional lead screw 23 is rotatably installed in the second sliding groove 202. The two second clamping blocks 24 are symmetrically distributed on the second bidirectional lead screw 23 and are threadedly connected to the second bidirectional lead screw 23. The threads of the second bidirectional lead screw 23 are opposite to those of the two second clamping blocks 24. The two second clamping blocks 24 are clamped and engaged with the rectangular frame 1 along the width direction.

[0030] The second bidirectional lead screw 23 and the two second clamping blocks 24 can clamp the rectangular frame 1 along its width. Combined with the clamping action of the first bidirectional lead screw 21 and the two first clamping blocks 22 along its length, this achieves four-sided clamping and fixing of the rectangular frame 1, improving the stability of the base structure 2 in fixing the rectangular frame 1. Furthermore, the depth of the second slide groove 202 is less than the depth of the first slide groove 201, and the second bidirectional lead screw 23 and the first bidirectional lead screw 21 are arranged vertically at intervals, avoiding mutual interference between the two bidirectional lead screws and ensuring the reliability of the spacing adjustment between the two first clamping blocks 22 and the two second clamping blocks 24.

[0031] Specifically, the second bidirectional lead screw 23 and the two second clamping blocks 24 form a front and rear clamping structure. There are two front and rear clamping structures, which are arranged symmetrically about the center of the first slide groove 201. The two symmetrically arranged front and rear clamping structures can provide two front and rear clamping effects on the rectangular frame 1, thereby improving the constraint stability of the base structure 2 on the rectangular frame 1.

[0032] In this embodiment, a second rocker arm 26 is installed on the side of the base body 20 corresponding to its width direction. The second rocker arm 26 is connected to a second bidirectional lead screw 23 to prevent rotation. A gear 27 is fixed in the middle of each of the two second bidirectional lead screws 23, and a synchronous belt 28 is connected between the two gears 27. The two second bidirectional lead screws 23 are connected by transmission through the gears 27 and the synchronous belt 28, ensuring the synchronicity of the rotation angle of the second bidirectional lead screws 23, thereby achieving the purpose of synchronous adjustment of the two front and rear clamping structures.

[0033] Correspondingly, a first rocker arm 25 is mounted on the side of the base body 20 along its length. The first rocker arm 25 is connected to the first bidirectional lead screw 21 for anti-rotation. A handle 251 is mounted at an eccentric position on the first rocker arm 25. The handle 251 is movable along the axis parallel to the first bidirectional lead screw 21. The base body 20 also has a limiting hole 203 facing the first rocker arm 25, and the handle 251 is inserted into the limiting hole 203. Furthermore, there are multiple limiting holes 203, which are axially spaced from the rotational contour of the first rocker arm 25. A return spring 252 is also provided between the handle 251 and the first rocker arm 25.

[0034] The return spring 252 generates an elastic pulling force on the handle 251. When the first bidirectional lead screw 21 needs to be rotated, the handle 251 is pulled outward first, and the first crank 25 can be rotated smoothly. When the two first clamping blocks 22 generate a reliable clamping force on the rectangular frame 1, the handle 251 is released and the return spring 252 drives the handle 251 to automatically insert into the corresponding limiting hole 203, thus achieving the purpose of reliable mechanical locking.

[0035] In addition, the first clamping block 22 has first protruding ribs 224 on both sides, and the first sliding groove 201 has first guide grooves (not shown in the figure) on both sides of the groove wall. The first protruding ribs 224 and the first guide grooves are guided and engaged along the length direction of the base body 20. The second clamping block 24 has second protruding ribs 241 on both sides, and the second sliding groove 202 has second guide grooves on both sides of the groove wall. The second protruding ribs 241 and the second guide grooves are guided and engaged along the width direction of the base body 20. The first protruding ribs 224 are guided and engaged with the first guide grooves of the first sliding groove 201, and the second protruding ribs 241 are guided and engaged with the second guide grooves of the second sliding groove 202, which ensures the smooth sliding of the first clamping block 22 and the second clamping block 24 and prevents the clamping blocks from disengaging from the sliding grooves.

[0036] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
