Description

Technical Field

[0001] This invention relates to the field of wind power equipment transportation and installation technology, and in particular to a wind turbine tower storage and transportation device and its transportation method. Background Technology

[0002] With the increasing prominence of environmental issues and the tightness of energy supply, wind energy, as a clean and renewable new energy source, is receiving more and more attention. Wind power generation is gradually becoming one of the largest and most mature power generation methods among new energy technologies. When constructing offshore wind farms, a large number of towers need to be transported by wind turbine installation vessels. Due to the large size of the towers, they may deform under their own weight when stored horizontally, and are prone to tipping over when stored vertically, making them difficult to secure. This brings inconvenience to the batch transportation and storage of towers. Summary of the Invention

[0003] The purpose of this invention is to provide a wind turbine tower storage and transportation device and method, which facilitates the batch vertical storage of towers, avoids the deformation problem caused by horizontal storage, and is easy and quick to install, not easy to tip over, and is safer and simpler.

[0004] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

[0005] A wind turbine tower storage and transportation device includes a storage and transportation base with several storage and transportation stations. Each storage and transportation station is used to vertically place a wind turbine tower. The storage and transportation station is provided with several bottom positioning blocks at the lower level and several telescopic positioning blocks at the upper level. The bottom positioning blocks abut against the outer periphery of the wind turbine tower and have a guide slope on the inner side of the top. The telescopic positioning blocks slide along the direction of approaching or moving away from the outer periphery of the wind turbine tower. The telescopic positioning blocks are also connected to a locking member for driving them to abut against the outer periphery of the wind turbine tower.

[0006] Furthermore, the locking component includes a rotating disk rotatably connected to the storage and transportation base. The rotating disk has several rotating protrusions on its inner circumference, with gaps between adjacent rotating protrusions. The rotation path of the rotating disk passes through a locked position and an unlocked position.

[0007] When the rotating disc rotates to the locked position, the rotating protrusion on it abuts against the corresponding telescopic positioning block, and the telescopic positioning block extends and abuts against the outer periphery of the wind turbine tower.

[0008] When the rotating disc is rotated to the unlocked position, the gap between adjacent rotating protrusions aligns with the corresponding telescopic positioning block, and the telescopic positioning block retracts to allow the wind turbine tower to enter or leave.

[0009] Furthermore, the storage and transportation station is equipped with several fixed seats, and the telescopic positioning block is inserted into the corresponding fixed seat and slides therein.

[0010] Furthermore, the sliding direction of the telescopic positioning block is tilted, and the tilting direction is upward on the side away from the fixed seat.

[0011] Furthermore, the storage and transportation base is also equipped with a rotation drive component that drives one or more rotating discs to rotate together.

[0012] Furthermore, the rotation drive component includes a drive gear, which is driven to rotate by a motor, and the outer circumference of the rotating disk has a tooth profile that matches the drive gear.

[0013] Furthermore, the bottom positioning block is hinged to the storage and transportation base, and a pressure block is connected to the lower end of the bottom positioning block inward. The bottom positioning block abuts against the outer periphery of the wind turbine tower, and the pressure block abuts against the lower end of the wind turbine tower.

[0014] Furthermore, the storage and transportation base has a moving groove for the pressure block to move radially, and a hinge seat is detachably connected in the moving groove, with the bottom positioning block hinged to the hinge seat at its bottom.

[0015] Furthermore, the storage and transportation base is also equipped with at least one flipping device, which includes a rotating flipping plate. A flipping limit block is vertically connected to the flipping plate. After the flipping plate rotates to the vertical position, the flipping limit block is located at the lower position. The wind turbine tower is horizontally transported to one end and moved to the top of the flipping limit block. The wind turbine tower is lifted at the other end and drives the flipping plate to flip to the horizontal position. The wind turbine tower is placed vertically on the flipping plate.

[0016] The present invention also discloses a transportation method for a wind turbine tower storage and transportation device, comprising the following steps;

[0017] Step S10: The wind turbine tower is pre-rotated to a vertical position;

[0018] In step S20, the telescopic positioning block slides away from the outer periphery of the wind turbine tower, and the crane lifts the wind turbine tower vertically upward and moves it to the corresponding storage and transportation position, so that the lower end of the wind turbine tower abuts against the corresponding bottom positioning block.

[0019] In step S30, the telescopic positioning block slides along the direction close to the outer periphery of the wind turbine tower, and the locking mechanism drives the telescopic positioning block to press against the outer periphery of the wind turbine tower.

[0020] Step S40: Repeat steps S10 to S30 to move the wind turbine tower to the corresponding storage and transportation station, complete the placement of the wind turbine tower on the entire storage and transportation base, and carry out storage or overall transportation.

[0021] In summary, the present invention has the following beneficial effects:

[0022] The horizontal wind turbine tower is transported to one end and moved directly above the tilting limit block. The other end is lifted by a crane. As the crane continuously lifts the tower and approaches the tilting station, it drives the tilting plate to tilt to the horizontal. This allows the crane to lift the wind turbine tower vertically upward and move it to the corresponding storage and transportation station. The bottom positioning block self-aligns and the telescopic positioning block locks to achieve double-layer positioning and fixation, improving the safety of storage and transportation.

[0023] Furthermore, the bottom positioning block and telescopic positioning block can be easily replaced or moved according to the size of the wind turbine tower, improving its applicability and facilitating the vertical placement of wind turbine towers of different specifications on the entire storage and transportation base, as well as batch storage or overall transportation, making it safer and simpler.

Detailed Implementation

[0028] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. These embodiments do not constitute a limitation of the present invention. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application.

[0029] A wind turbine tower storage and transportation device, such as Figure 1As shown, the system includes a storage and transportation base 1, which has several storage and transportation stations and at least one flipping station. Each storage and transportation station is used to vertically place a wind turbine tower. In this embodiment, a base plate is detachably connected to the storage and transportation base 1 by bolts. One base plate corresponds to one storage and transportation station or flipping station. A fixed truss 11 is fixed to the storage and transportation base 1 by welding. The fixed truss 11 includes a top limiting frame and several vertical fixing rods. The limiting frame is grid-shaped, with each grid corresponding to one storage and transportation station. The vertical fixing rods are fixed between the top limiting frame and the storage and transportation base 1. Several reinforcing diagonal rods 12 are also fixedly connected between the top of the outer periphery of the fixed truss 11 and the outer periphery of the upper side of the storage and transportation base 1. There are two flipping stations, which are symmetrically arranged on the storage and transportation base 1 and located outside the top limiting frame.

[0030] like Figure 1 As shown, a flipping device 2 is detachably connected to the flipping station by screws. The flipping device 2 can be any existing technology that can flip the tower by 90 degrees. In this embodiment, the flipping device 2 includes a rotating flipping plate 21, which flips back and forth between a horizontal position and a vertical position. A flipping limiting block 22 is vertically connected to the flipping plate 21. After the flipping plate 21 rotates to the vertical position, the flipping limiting block 22 is located at its lower outer side. The wind turbine tower is horizontally transported to one end and moves to directly above the flipping limiting block 22 (abutting against the flipping limiting block 22 or having a gap with it). The wind turbine tower is lifted at the other end (or lifted by other two-point methods, etc.) and, during its flipping process, drives the flipping plate 21 to flip to the horizontal, so that the wind turbine tower is finally placed vertically on the flipping plate 21.

[0031] In this embodiment, the flipping limiting block 22 is a V-shaped block (there can be two symmetrical V-shaped blocks, so that the tower is completely limited between the two, or a limiting rope or the like can be used to limit one side). The flipping plate 21 is vertically connected to the side plate on one side. The flipping limiting block 22 is fixed on the side plate and the flipping plate 21. The outer side of the side plate is connected to the abutment seat. When the side plate is flipped to the horizontal and the flipping plate 21 is vertical, the abutment seat abuts against the ground, so that the wind turbine tower can be transported laterally to the top of the flipping limiting block 22. The flipping plate 21 can also be connected to a fixing device such as a pin, so that the flipping plate 21 is horizontally fixed on the storage and transportation base 1 when it is not needed.

[0032] like Figure 2 and Figure 3 As shown, the storage and transportation station is provided with a number of bottom positioning blocks 3 at the lower level and a number of telescopic positioning blocks 41 at the upper level. The bottom positioning blocks 3 abut against the outer periphery of the wind turbine tower, and a guide slope 31 is opened on the inner side of the top (the side closer to the wind turbine tower) to guide the wind turbine tower into the space between the bottom positioning blocks 3.

[0033] To further facilitate the entry of the wind turbine tower, the bottom positioning block 3 is hinged to the storage and transportation base 1. The bottom end of the bottom positioning block 3 is vertically connected to the pressure block 32. The bottom positioning block 3 is vertical and abuts against the outer periphery of the wind turbine tower, and the pressure block 32 is horizontal and abuts against the lower end of the wind turbine tower. The bottom positioning block 3 can also be driven by elastic elements or torsion springs at the hinge shaft to make the pressure block 32 horizontally abut against the upper side of the storage and transportation station under normal conditions. At the same time, the bottom positioning block 3 can be pushed open to make the wind turbine tower enter more easily. When the wind turbine tower continues to descend, the bottom end of the wind turbine tower is finally abutted against the pressure block 32 by the inner side of the bottom positioning block 3. The bottom positioning block 3 can be positioned on the pressure block 32 by elastic elements or manual pushing. A limiting plate can also be connected to the storage and transportation base 1 to limit the rotation range of the bottom positioning block 3.

[0034] like Figure 2 and Figure 3 As shown, in order to improve the versatility for towers of different specifications, a moving groove for the pressure block 32 to move radially is opened on the storage and transportation base 1. A hinge seat is detachably connected in the moving groove. The bottom positioning block 3 is hinged to the bottom of the hinge seat (the hinge seat is installed at different positions of the sliding groove by means of downward insertion or bolt connection). A buffer layer such as a rubber layer can be connected to the inner side of the bottom positioning block 3 to reduce rigid collision with the wind turbine tower.

[0035] like Figure 2 and Figure 3 As shown, the telescopic positioning block 41 slides along the direction of approaching or moving away from the outer periphery of the wind turbine tower. The telescopic positioning block 41 is also connected to a locking element that drives it to press against the outer periphery of the wind turbine tower. The locking element includes a rotating disk 5 rotatably connected to the storage and transportation base 1. Several rotating protrusions 51 are fixedly arranged in an array on the inner periphery of the rotating disk 5. There is a gap between adjacent rotating protrusions 51. The two ends of the rotating protrusions 51 gradually transition to the gap through an arc or oblique line. The rotation path of the rotating disk 5 passes through the locking position and the unlocking position.

[0036] Rotate the rotating disc 5 to the locked position, and the rotating protrusion 51 on it abuts against the corresponding telescopic positioning block 41. The telescopic positioning block 41 extends out and abuts against the outer periphery of the wind turbine tower.

[0037] Rotate the rotating disc 5 to the unlocked position, align the gap between adjacent rotating protrusions 51 with the corresponding telescopic positioning block 41, and the telescopic positioning block 41 retracts to allow the wind turbine tower to enter or leave.

[0038] In this embodiment, a number of fixed seats 4 are fixed in the limiting frame on the storage and transportation station. The telescopic positioning block 41 is inserted into the corresponding fixed seat 4 and slides therein. The telescopic positioning block 41 is directly inserted, which makes it easy to replace it with different thicknesses and outer surface curvatures (the inner surface curvature remains unchanged to maintain a stable fit and contact with the rotating wheel 5) to adapt to different towers. In addition, the limiting frame can also be connected to rotating components such as bearings or supporting components to realize the installation of the rotating wheel 5.

[0039] The storage and transportation base 1 is also provided with a rotation drive component that drives one or more rotating disks 5 to rotate together. The rotation drive component includes a drive gear 52, which is driven to rotate by a motor. The motor is fixed on the limit frame or the storage and transportation base 1. The outer periphery of the lower end of the rotating disk 5 is provided with a tooth profile that matches the drive gear 52. The drive gear 52 can mesh with the outer periphery of one or more rotating disks 5 to realize the simultaneous rotation of one or more rotating disks 5.

[0040] The telescopic positioning block 41 is tilted in the sliding direction, and the tilt direction is upward away from the fixed base 4, so that the telescopic positioning block 41 tends to retract downward under its own weight, which facilitates the wind turbine tower to enter or leave.

[0041] The present invention also discloses a transportation method for a wind turbine tower storage and transportation device, comprising the following steps;

[0042] Step S10: The wind turbine tower is placed horizontally on the conveyor trolley and transported to the turning station by the conveyor trolley.

[0043] The horizontal wind turbine tower is transported to one end and moved to the top of the flipping limit block 22. The other end is lifted by a crane. As the crane is continuously lifted upward and approaches the flipping station, it drives the flipping plate 21 to flip to the horizontal, so that the wind turbine tower flips to the vertical state.

[0044] In step S20, the telescopic positioning block 41 slides away from the outer periphery of the wind turbine tower, and the crane lifts the wind turbine tower vertically upward and moves it to the corresponding storage and transportation position, so that the lower end of the wind turbine tower abuts against the corresponding bottom positioning block 3.

[0045] In step S30, the drive gear 52 is driven to rotate by the motor, causing the rotating disk 5 to rotate to the locked position. The rotating protrusion 51 on it abuts against the corresponding telescopic positioning block 41. The telescopic positioning block 41 slides along the direction close to the outer periphery of the wind turbine tower, gradually extending and pressing against the outer periphery of the wind turbine tower.

[0046] Step S40: Repeat steps S10 to S30 to move the wind turbine tower to the corresponding storage and transportation station, complete the placement of the wind turbine tower on the entire storage and transportation base 1, and carry out storage or overall transportation.

[0047] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within the scope of its essence and protection. Such modifications or equivalent substitutions should also be considered to fall within the protection scope of the present invention.
