Description

Technical Field

[0001] This invention belongs to the field of wind turbine blade transportation technology, and relates to a wind turbine blade storage device and its usage method, specifically a wind turbine blade storage device and its usage method for offshore wind power installation vessels. Background Technology

[0002] Wind turbine blades typically consist of a blade body, a blade root, and a blade tail. Wind turbine blades are key components in wind turbine generators used to capture wind energy and convert it into mechanical energy.

[0003] In offshore wind power projects, the wind turbine blades must first be transported to the vicinity of the offshore foundation using an offshore wind turbine installation vessel, and then the installation work is completed at sea. When transporting wind turbine blades at sea using an offshore wind turbine installation vessel, a wind turbine blade storage device is required to secure the blades. Existing wind turbine blade storage devices typically include storage racks, on which the blades are placed. However, existing wind turbine blades are quite long, and current storage devices can only support the two ends (blade root and blade tail), not the main body of the blade. In rough seas at sea, this can easily cause significant deformation of the blade body, potentially leading to breakage. Furthermore, existing storage devices cannot effectively limit the movement of the blades, allowing them to shift during transport at sea, severely compromising the safety of the offshore wind turbine installation vessel during transport. Summary of the Invention

[0004] To address the aforementioned shortcomings in the existing technology, this invention aims to provide a wind turbine blade storage device and its usage method for offshore wind turbine installation vessels, thereby improving the safety of transporting wind turbine blades on offshore wind turbine installation vessels.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a wind turbine blade storage device for offshore wind power installation, comprising a lower base mechanism, an upper base mechanism detachably connected to the lower base mechanism, a support and limiting mechanism disposed between the lower base mechanism and the upper base mechanism for supporting and limiting the blade body of the wind turbine blade, and a positioning mechanism slidably connected to the lower base mechanism for positioning the root of the wind turbine blade, wherein the lower base mechanism and the upper base mechanism cooperate to place the wind turbine blade and support and limit the two ends of the wind turbine blade.

[0006] As a limitation of the present invention, the lower base mechanism includes a lower base, a first semi-annular member fixed at the front end of the lower base, and a first groove provided at the rear end of the lower base; the upper base mechanism includes an upper base, a second semi-annular member fixed at the front end of the upper base, and a second groove provided at the rear end of the upper base, wherein the lower base and the upper base together form a blade body placement space for placing the blade body of the wind turbine blade, the first semi-annular member and the second semi-annular member together form a blade tail placement space for placing the blade tail of the wind turbine blade, and the first groove and the second groove together form a blade root placement space for placing the blade root of the wind turbine blade.

[0007] As a further limitation of the present invention, the supporting and limiting mechanism includes a drive screw rotatably mounted on the lower base and at least two lifting frames vertically slidably connected to the lower base. The upper base is fixed with an upper limit member of the same number as the lifting frames at intervals. Each lifting frame is fixed with a support plate at its top. The drive screw is threaded with a slider of the same number as the lifting frame. A connecting rod is provided between the lifting frame and the corresponding slider. The two ends of the connecting rod are respectively hinged to the slider and the lifting frame to realize the conversion of the horizontal movement of the slider into the lifting movement of the lifting frame.

[0008] As a further limitation of the present invention, a flexible rubber layer is fixed on the outer surfaces of the support plate, the first semi-annular component, and the second semi-annular component.

[0009] As another limitation of the present invention, the positioning mechanism includes a movable frame threadedly connected to a drive screw, a rotating disk rotatably mounted on the movable frame, a positioning screw threadedly connected to the movable frame for positioning the rotating disk, a horizontal guide rod fixed on the movable frame and slidably connected to the lower base mechanism, a turbine fixed on the end of the drive screw, and a worm gear drivenly connected to the turbine and rotatably mounted on the lower base mechanism; the rotating disk is provided with multiple insertion holes adapted to multiple blade fixing screws in the blade root, and the multiple blade fixing screws can be correspondingly inserted into the multiple insertion holes.

[0010] As a further limitation of the present invention, a handheld operating head is fixedly provided at the end of the worm gear.

[0011] The present invention also provides a method for using the above-mentioned offshore wind turbine blade storage device, comprising the following steps: Step 1: placing the wind turbine blade on the lower base mechanism, such that the blade root is located in the blade root placement space, the blade tail is located in the blade tail placement space, and the blade body is located in the blade body placement space; Step 2: driving the positioning mechanism to operate, and stopping the operation of the positioning mechanism when the supporting and limiting mechanism supports the blade body and the positioning mechanism locks the blade root; Step 3: fixing the upper base mechanism on the lower base mechanism.

[0012] By adopting the above-described technical solution, the beneficial effects achieved by this invention compared to the prior art are as follows:

[0013] (1) The present invention adopts a structure combining a lower base mechanism, an upper base mechanism, a support and limiting mechanism and a positioning mechanism. The lower base mechanism and the upper base mechanism can place the wind turbine blade and support and limit the two ends of the wind turbine blade. The support and limiting mechanism can support and limit the main body of the blade. The positioning mechanism can position the root of the blade. Through the cooperation of the lower base mechanism, the upper base mechanism, the support and limiting mechanism and the positioning mechanism, reliable limiting of the wind turbine blade can be achieved. In addition, the present invention can support both ends of the wind turbine blade and the main body of the blade at the same time, which can significantly reduce the bending stress caused by wind and waves during the transportation of the wind turbine blade at sea. This can effectively prevent large deformation of the main body of the blade and breakage of the main body of the blade, and effectively improve the safety of transporting wind turbine blades on offshore wind turbine installation vessels.

[0014] (2) The lower base mechanism and the upper base mechanism in this invention have ingenious structural design. The blade body placement space formed by the lower base and the upper base can place the blade body. The blade tail placement space formed by the first semi-annular component and the second semi-annular component can place the blade tail. The blade root placement space formed by the first groove and the second groove can place the blade root. The lower base mechanism and the upper base mechanism cooperate with each other to realize the placement of the wind turbine blade and the support and limiting of both ends of the wind turbine blade.

[0015] (3) The supporting and limiting mechanism in this invention has high structural reliability and is easy to use. It can reliably support and limit the blade body through simple operation. Specifically, when in use, rotating the drive screw can raise each lifting frame. The lifting frame can drive each supporting plate to rise and reliably support the bottom of the blade body. At the same time, each upper limit component and each supporting plate cooperate with each other to reliably limit the blade body and can stably support and limit the blade body.

[0016] (4) In this invention, a flexible rubber layer is fixed on the outer surface of the support plate, the first semi-annular component and the second semi-annular component, which can prevent the support plate, the first semi-annular component and the second semi-annular component from damaging the wind turbine blade when they come into contact with the wind turbine blade. In addition, the flexible rubber layer can play a shock-absorbing and buffering role during sea transportation, which can further prevent damage to the wind turbine blade.

[0017] (5) In this invention, the positioning mechanism and the supporting and limiting mechanism are linked, which can improve the convenience of operation. When in use, the positioning mechanism can be used to position the root of the blade, while the supporting and limiting mechanism can support and limit the main body of the blade.

[0018] In summary, this invention features an ingenious structural design, ease of use, and strong practicality. Through the coordinated operation of the lower base mechanism, upper base mechanism, support and limiting mechanism, and positioning mechanism, it achieves reliable positioning of the wind turbine blade. Furthermore, this invention can simultaneously support both ends of the wind turbine blade and the blade body, significantly reducing the bending stress caused by wind and waves during maritime transport. This effectively prevents significant deformation and breakage of the blade body, thus significantly improving the safety of transporting wind turbine blades on offshore wind turbine installation vessels. This invention is suitable for use when transporting wind turbine blades at sea using wind turbine installation vessels. Attached Figure Description

It should be understood that the preferred embodiments described herein are for illustrative and understanding purposes only and are not intended to limit the scope of the invention.

[0027] Example 1: A wind turbine blade storage device for offshore wind power installation vessels

[0028] like Figure 1, Figure 3 As shown, this embodiment 1 includes a lower base mechanism, an upper base mechanism detachably connected to the lower base mechanism, a support and limiting mechanism disposed between the lower base mechanism and the upper base mechanism for supporting and limiting the blade body in the wind turbine blade 25, and a positioning mechanism slidably connected to the lower base mechanism for positioning the root of the wind turbine blade 25. The lower base mechanism and the upper base mechanism cooperate with each other to place the wind turbine blade 25 and support and limit both ends of the wind turbine blade 25.

[0029] The lower base mechanism includes a lower base 1, a first semi-annular member 2 fixed at the front end of the lower base 1, and a first groove 3 located at the rear end of the lower base 1. The first groove 3 is a downwardly recessed semi-circular groove, and a flexible rubber layer is fixed on the outer surface of the first semi-annular member 2.

[0030] The upper base mechanism includes an upper base 4, a second semi-annular member 5 fixed to the front end of the upper base 4, and a second groove 6 located at the rear end of the upper base 4. The second groove 6 is an upwardly recessed semi-circular groove, and a flexible rubber layer is fixed to the outer surface of the second semi-annular member 5. The upper base 4 and the lower base 1 are detachably connected together by multiple bolts. The lower base 1 and the upper base 4 together form a blade body placement space for placing the blade body of the wind turbine blade 25. The first semi-annular member 2 and the second semi-annular member 5 together form a blade tail placement space for placing the tail portion of the wind turbine blade 25. The first groove 3 and the second groove 6 together form a blade root placement space for placing the root portion of the wind turbine blade 25. After the wind turbine blade 25 is placed on the upper base mechanism and the lower base mechanism, the first semi-annular member 2 and the second semi-annular member 5 can support and limit the tail portion of the blade, and the first groove 3 and the second groove 6 can support and limit the root portion of the blade.

[0031] The supporting and limiting mechanism includes a drive screw 7 rotatably mounted on the lower base 1 and at least two lifting frames 9 vertically slidably connected to the lower base 1. The upper base 4 is fixed with an upper limit member 18 at intervals, the same number as the lifting frame 9. Each lifting frame 9 has a support plate 11 fixed on its top. The drive screw 7 is threaded with a slider 8 of the same number as the lifting frame 9. A connecting rod member is provided between the lifting frame 9 and the corresponding slider 8. The two ends of the connecting rod member are respectively hinged to the slider 8 and the lifting frame 9 to realize the conversion of the horizontal movement of the slider 8 into the lifting movement of the lifting frame 9. Specifically, in this embodiment 1, two lifting frames 9 and two upper limit components 18 are provided. A slider 8 is threadedly connected to the right side of each of the two lifting frames 9 on the drive screw 7. A connecting rod is provided between the lifting frame 9 and the adjacent slider 8. Two vertical guide rods 10 are fixed on the lower base 1 near the left side of each lifting frame 9. Each lifting frame 9 is vertically slidably connected to the corresponding two vertical guide rods 10. Each slider 8 can slide horizontally on the lower base 1. The support plate 11 is a first arc-shaped plate adapted to the blade body, and a flexible rubber layer is fixed on the outer surface of the support plate 11. The upper limit component 18 includes a mounting frame fixed to the upper base 4 and a second arc-shaped plate adapted to the blade body fixed to the bottom of the mounting frame. Figure 2 , Figure 4 As shown, the linkage component includes two first mounting plates 12 fixed at intervals on the lifting frame 9, a first connecting shaft 13 fixed between the two first mounting plates 12, two second mounting plates 14 fixed at intervals on the slider 8, a second connecting shaft 15 and a third connecting shaft respectively fixed on the two second mounting plates 14, a first linkage body 16 hinged between the first connecting shaft 13 and the second connecting shaft 15, and a second linkage body 17 hinged between the first connecting shaft 13 and the third connecting shaft. It should be noted that the second connecting shaft 15 and the third connecting shaft are arranged opposite to each other, and both the second connecting shaft 15 and the third connecting shaft need to be arranged to avoid the drive screw 7 to avoid affecting the rotation of the drive screw 7.

[0032] The positioning mechanism includes a movable frame 19 threadedly connected to the drive screw 7, a rotating disk 21 rotatably mounted on the movable frame 19, a positioning screw 22 threadedly connected to the movable frame 19 to position the rotating disk 21, a horizontal guide rod 20 fixedly mounted on the movable frame 19 and slidably connected to the lower base mechanism, a turbine 23 fixedly mounted at the end of the drive screw 7, and a worm gear 24 rotatably mounted on the lower base mechanism and connected to the turbine 23 in a transmission manner.

[0033] Example 2: Method of using a wind turbine blade storage device

[0034] This embodiment 2 provides a method for using a wind turbine blade storage device, such as... Figure 5 As shown, it utilizes a marine wind turbine blade storage device for offshore wind power installation provided in Embodiment 1, and includes the following steps:

[0035] Step 1: Use hoisting equipment to place the wind turbine blade 25 on the lower base mechanism, so that the blade root is in the blade root placement space, the blade tail is in the blade tail placement space, and the blade body is in the blade body placement space.

[0036] Step 2: Drive the positioning mechanism to operate. When the supporting and limiting mechanism supports the blade body and the positioning mechanism locks the blade root, stop driving the positioning mechanism to operate. Specifically, in this embodiment 2, the hand-held operating head is rotated by hand. The rotation of the hand-held operating head drives the worm 24 to rotate, the rotation of the worm 24 drives the turbine 23 to rotate, the rotation of the turbine 23 drives the drive screw 7 to rotate, and the rotation of the drive screw 7 drives the moving frame 19 to move closer to the blade root. When the moving frame 19 moves and drives the inner side of the rotating disk 21 to approach the positions of multiple blade fixing screws 26 at the blade root, rotate the rotating disk 21 to align the positions of multiple insertion holes with the positions of multiple blade fixing screws 26. Then continue to rotate the hand-held operating head, and the moving frame 19 continues to move closer to the blade root. This allows multiple blade fixing screws 26 to be inserted into multiple insertion holes. While the drive screw 7 rotates and drives the moving frame 19 to move, the drive screw 7 also drives the two sliders 8 to move together. The movement of the two sliders 8 drives the two connecting rod components to move. The movement of the two connecting rod components drives the two lifting frames 9 to rise along the corresponding two vertical guide rods 10, thereby allowing the two support plates 11 to support the blade body. When the moving frame 19 moves completely close to the lower base 1, the support and limiting mechanism can stably support the blade body and the positioning mechanism can reliably lock the blade root. At this time, the hand-held operating head can be stopped from being rotated manually.

[0037] Step 3: Use hoisting equipment to hoist the upper base mechanism directly above the lower base mechanism, and use appropriate bolts to fix the upper base mechanism onto the lower base mechanism.

[0038] It should be noted that when the offshore wind turbine installation vessel transports the wind turbine blades 25 stored in the wind turbine blade storage device to the designated location, and it is necessary to disassemble the wind turbine blades 25, it is only necessary to reverse the above-mentioned operation method. It will not be described in detail here, but only briefly. That is, first disassemble the upper base mechanism and the lower base mechanism, then release the positioning mechanism from the positioning of the blade root, release the support and limit mechanism from the support and limit of the blade body, and finally use the hoisting equipment to hoist the wind turbine blades 25 to the corresponding position.

[0039] It should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
