Description

Technical Field

[0001] This application relates to the field of tower transportation technology, and in particular to a wind turbine tower offshore transportation support. Background Technology

[0002] Because offshore wind farms do not occupy land area, offshore wind power is increasingly becoming an important development direction in my country's wind power generation field. The construction of offshore wind farms requires transporting wind power equipment components to the vicinity of the offshore foundation via ocean transport ships. After transportation, the wind power equipment is installed at sea. Among them, the tower is the basic component of the wind power equipment, usually composed of multiple cylindrical sections. It serves as the installation and support foundation for the wind turbine equipment, influencing and determining the installation height and stability of the wind turbine.

[0003] When transporting wind turbine towers, due to the large number of tower sections and the susceptibility to turbulence caused by waves during sea transport, support brackets are needed to support the tower sections. However, existing wind turbine tower support brackets are usually of fixed size and cannot be adapted to wind turbine tower sections of varying sizes, resulting in poor applicability and significant shortcomings. Utility Model Content

[0004] To improve the applicability of wind turbine tower transport support, this application provides a wind turbine tower offshore transport support.

[0005] The offshore transport support for wind turbine towers provided in this application adopts the following technical solution:

[0006] A wind turbine tower offshore transport support includes a base, with clamps slidably connected to opposite sides of the base. A drive assembly is provided on the base to move the clamps along the length of the base. Each clamp has a fixing assembly, which includes a support cylinder disposed on the clamp. The support cylinder has multiple circumferentially spaced limiting slots, the length of each limiting slot being parallel to the radial direction of the support cylinder. A fixing rod is slidably connected within each limiting slot. The end of each fixing rod extends out of the support cylinder and is fitted with a fixing plate. A moving assembly is provided on the support cylinder to drive the multiple fixing rods to move synchronously.

[0007] By adopting the above technical solution, after the wind turbine section is placed on the base, the drive assembly drives two clamping plates to move towards each other until the clamping plates abut against the end face of the section. This achieves the limitation of different length sections in the length direction of the base. At the same time, the clamping plates drive the support cylinder to extend into the interior of the section. Subsequently, the moving assembly drives multiple fixed rods inside the support cylinder to move synchronously towards the inner sidewall of the section. When the fixed plate abuts against the inner sidewall of the section, it achieves the limitation of different cross-sectional sizes of sections in the width direction of the base. Thus, it finally achieves the fixation of wind turbine towers of different sizes on the base, improving the applicability of the wind turbine tower transport support.

[0008] Optionally, the moving component includes a moving motor disposed on the clamp plate away from the surface of the support cylinder. The output shaft of the moving motor is coaxially fixedly connected to a lead screw, which is rotatably connected inside the support cylinder. A driving block is threaded onto the lead screw. The driving block is frustum-shaped, and a plurality of fixed rods are circumferentially and evenly distributed on the outer surface of the driving block. Each fixed rod is slidably connected to the outer surface of the driving block along the generatrix of the driving block.

[0009] By adopting the above technical solution, after the support cylinder enters the cylinder section, the moving motor is started, and the moving motor drives the lead screw to rotate. Since the drive block cannot rotate due to the restriction of the fixed rod and the limiting through groove, the rotation of the lead screw drives the drive block to move along the axis of the support cylinder. As the drive block moves from the small diameter end to the large diameter end, the fixed rod moves away from the lead screw along the length of the limiting through groove. The height of the fixed rod extending out of the limiting through groove increases continuously, so that the fixing plate gradually approaches the cylinder section and finally abuts against the inner wall of the cylinder section. This achieves the fixing of cylinder sections with different cross-sectional areas. At the same time, the moving component drives multiple fixed rods to move synchronously, improving the installation efficiency of the cylinder section on the bracket.

[0010] Optionally, the base has a drive groove and a sliding groove on opposite sides. The length direction of the drive groove and the sliding groove is parallel to the length direction of the base. The drive assembly includes a bidirectional lead screw rotatably connected in the drive groove, a sliding rod fixedly connected in the sliding groove, and two clamping plates threadedly connected to the two ends of the bidirectional lead screw with opposite thread directions. The end of the clamping plate away from the bidirectional lead screw is slidably connected to the sliding groove. The base is provided with a drive motor for driving the bidirectional lead screw to rotate.

[0011] By adopting the above technical solution, after the wind turbine tower section is placed on the base, the drive motor is started. The drive motor drives the bidirectional lead screw to rotate in the drive groove. Under the restriction of the sliding groove, the rotation of the bidirectional lead screw drives the two clamping plates to move towards or relative to each other along the length direction of the bidirectional lead screw until the opposite end faces of the clamping plates abut against the outer end face of the tower section, thereby realizing the fixation of tower sections of different lengths.

[0012] Optionally, each of the two clamping plates has a buffer airbag on its opposite surface, each fixing plate has a rubber pad on its surface facing the wind turbine tower, and the base is provided with an inflation assembly for inflating the buffer airbag.

[0013] By adopting the above technical solution, after the wind turbine tower is placed on the base, the inflation component inflates the buffer airbag. The inflated buffer airbag abuts against the outer end face of the wind turbine tower, while the rubber pad abuts against the inner wall of the tower section. This arrangement provides a buffering effect for the wind turbine tower section. When the ship is rocking, the buffer airbag and rubber pad can effectively absorb the impact force, avoiding damage to the wind turbine tower due to hard collisions, and improving the stability of the wind turbine tower fixed on the support.

[0014] Optionally, the base has a groove, and multiple pressure plates are slidably connected to the groove along the width direction of the base. Multiple inflatable airbags corresponding to the pressure plates are provided on the inner bottom wall of the groove. The inflatable airbags are elastic airbags. The multiple inflatable airbags are connected to each other through connecting pipes. One of the inflatable airbags is connected to an air supply pipe corresponding to two of the buffer airbags. The air supply pipe is a corrugated pipe and is connected to the corresponding buffer airbag.

[0015] By adopting the above technical solution, after the wind turbine tower section is placed on the base, the weight of the section itself pushes the pressure plate towards the inflatable airbag. The inflatable airbag is continuously squeezed by the pressure plate. As the volume of the inflatable airbag decreases, the gas inside enters the buffer airbag through the air supply pipe, causing the buffer airbag to gradually inflate. When the buffer airbag is inflated, the drive assembly moves the drive clamp plate to drive the buffer airbag to abut against the outer end face of the tower, thereby providing buffer support for the section. After transportation is completed, the wind turbine tower is removed from the base by a crane. The pressure on the pressure plate disappears, and the inflatable airbag recovers its deformation under its own elasticity. The gas in the buffer airbag flows back to the inflatable airbag through the air supply pipe, so as to provide buffer support for the subsequent wind turbine tower.

[0016] Optionally, a shield is provided on the inner sidewalls of the drive groove, and the end of the shield away from the inner sidewall of the drive groove is provided on the clamping plate. When the two clamping plates are in contact with each other, the two shields together cover the bidirectional lead screw.

[0017] By adopting the above technical solution, when the base is not supporting the wind turbine tower, the drive component drives the two clamps to fit together. At this time, the two shields are fully extended and cover the outer surface of the bidirectional lead screw, which avoids the bidirectional lead screw from being corroded by the sea air when it is idle, thereby ensuring the smooth operation of the drive component.

[0018] Optionally, each end of the fixed rod near the drive block is provided with a guide block, and the drive block is provided with a guide groove along the generatrix direction that is slidably connected to the guide block.

[0019] By adopting the above technical solution, under the limitation of the guide block and the guide groove, the fixing rod can only move along the direction of the drive block generatrix, thereby reducing the possibility of the fixing rod tilting during the movement and ensuring the stability of the fixing rod driving the fixing plate during the fixing process.

[0020] Optionally, the base, the clamping plate, and the fixing plate are all coated with multiple layers of anti-corrosion coating.

[0021] By adopting the above technical solution, the multi-layer anti-corrosion coating can provide effective protection for the base, clamps and fixing plates, preventing them from being corroded by high humidity air, seawater droplets and various corrosive salts in the harsh marine environment, thereby extending the service life of the transport support.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. This application, by setting up a drive assembly, clamping plates, a moving assembly, and a fixing assembly, places the wind turbine section on the base. The drive assembly drives two clamping plates to move towards each other until the clamping plates abut against the end face of the section. This achieves the limitation of different length sections in the length direction of the base. At the same time, the moving assembly drives multiple fixing rods to move synchronously towards the inner wall of the section. When the fixing plate abuts against the inner wall of the section, it achieves the limitation of different cross-sectional sizes of sections in the width direction of the base. Thus, it finally achieves the fixing of wind turbine towers of different sizes on the base, improving the applicability of the wind turbine tower transport support.

[0024] 2. This application incorporates a buffer airbag, a rubber pad, and an inflation assembly. When the wind turbine tower is placed on the base, the inflation assembly inflates the buffer airbag. The inflated buffer airbag abuts against the outer end face of the wind turbine tower, while the rubber pad abuts against the inner wall of the tower section. This arrangement provides a buffering effect on the wind turbine tower section. When the ship pitches and rolls, the buffer airbag and rubber pad can effectively absorb the impact force, preventing damage to the wind turbine tower due to hard collisions and improving the stability of the wind turbine tower fixed on the support.

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0031] This application discloses an offshore transport support for wind turbine towers.

[0032] Reference Figure 1 A wind turbine tower offshore transport support includes a base 1, which supports the wind turbine tower section and is fixedly connected to the offshore transport vessel by bolts.

[0033] Reference Figure 1 and Figure 2 The base 1 has a drive groove 101 and a sliding groove 102 on opposite sides. The length direction of the drive groove 101 and the sliding groove 102 is parallel to the length direction of the base 1. The drive groove 101 and the sliding groove 102 are slidably connected to the opposite sides of the drive groove 101 and the sliding groove 102. The base 1 is provided with a drive assembly 3. Specifically, the drive assembly 3 includes a bidirectional lead screw 31 rotatably connected in the drive groove 101 and a sliding rod 32 fixedly connected in the sliding groove 102. The two clamps 2 are threadedly connected to the two ends of the bidirectional lead screw 31 with opposite thread directions. The end of the clamp 2 away from the bidirectional lead screw 31 is slidably connected to the sliding groove 102. The outer surface of the base 1 is fixedly installed with a drive motor 33 that drives the bidirectional lead screw 31 to rotate.

[0034] Reference Figure 1 and Figure 2Each clamping plate 2 is provided with a fixing component 4. The fixing component 4 includes a support cylinder 41 fixedly installed on the clamping plate 2. Two support cylinders 41 are arranged opposite to each other. Multiple limiting through grooves 411 are opened on the support cylinder 41. The multiple limiting through grooves 411 are evenly arranged circumferentially along the outer surface of the support cylinder 41. The length direction of each limiting through groove 411 is parallel to the radial direction of the support cylinder 41. A fixing rod 42 is slidably connected in each limiting through groove 411. A fixing plate 43 is fixedly connected to the end of each fixing rod 42 extending out of the support cylinder 41. A fixing plate 43 is fixedly connected to the end of the support cylinder 41. A rubber pad 431 for absorbing vibration energy is fixedly connected to the fixing plate 43. A moving component 5 is provided on the support cylinder 41 to drive the multiple fixing rods 42 to move synchronously.

[0035] Reference Figure 2 and Figure 3 The moving component 5 includes a moving motor 51 fixedly connected to the surface of the clamping plate 2 away from the support cylinder 41. The output shaft of the moving motor 51 is coaxially fixedly connected to a lead screw 52. The lead screw 52 is rotatably connected inside the support cylinder 41. The length direction of the lead screw 52 is parallel to the length direction of the support cylinder 41. A drive block 53 is threadedly connected to the lead screw 52. The drive block 53 is frustum-shaped. Multiple fixed rods 42 are evenly distributed circumferentially on the outer surface of the drive block 53. A guide block 421 is fixedly connected to the end of the fixed rod 42 near the drive block 53. The drive block 53 has a guide groove 531 along the generatrix direction that slides with the guide block 421. Under the guidance of the guide groove 531 and the guide block 421, the fixed rod 42 can only move along the generatrix direction of the drive block 53.

[0036] Reference Figure 2 and Figure 3 The base 1, clamping plate 2, and fixing plate 43 are all coated with multiple layers of anti-corrosion coating. In this embodiment, the multiple layers of anti-corrosion coating include an epoxy zinc-rich primer at the bottom layer to provide cathodic protection; an intermediate paint layer to enhance the coating thickness and shielding performance; and an outermost polyurethane topcoat with good weather resistance and seawater erosion resistance. This arrangement provides effective protection against the high humidity air, seawater droplets, and various corrosive salts in the harsh marine environment, thereby extending the service life of the transport support.

[0037] Before transportation, the wind turbine tower section is hoisted and placed on the base 1 by a crane. Then, the drive motor 33 is started. After the wind turbine section is placed on the base 1, the drive motor 33 drives the bidirectional lead screw 31 to rotate in the drive groove 101. Under the restriction of the sliding groove 102, the bidirectional lead screw 31 rotates and drives the two clamping plates 2 to move towards or relative to each other along the length direction of the bidirectional lead screw 31 until the opposite end faces of the clamping plates 2 abut against the outer end face of the section. At this time, the limit of different length sections in the length direction of the base 1 is realized.

[0038] After the clamping plate 2 abuts against the outer end face of the cylindrical section, the support cylinder 41 extends into the interior of the cylindrical section. At this time, the moving motor 51 is started, and the moving motor 51 drives the lead screw 52 to rotate. Since the driving block 53 cannot rotate due to the restriction of the fixed rod 42 and the limiting through groove 411, the rotation of the lead screw 52 drives the driving block 53 to move along the axis of the support cylinder 41. As the driving block 53 moves from the small diameter end to the large diameter end, the fixed rod 42 moves away from the lead screw 52 along the length direction of the limiting through groove 411. The height of the fixed rod 42 extending out of the limiting through groove 411 increases continuously, so that the fixed plate 43 gradually approaches the inner wall of the cylindrical section. When the rubber pad 431 on the fixed plate 43 abuts against the inner wall of the cylindrical section, the limitation of cylindrical sections with different cross-sectional sizes in the width direction of the base 1 is realized, thus finally realizing the fixation of wind turbine towers of different sizes on the base 1, improving the applicability of the wind turbine tower transport support.

[0039] Reference Figure 1 and Figure 2 Each memory cell opposite the drive slot 101 is fixedly connected with a shield 1011. In this embodiment, the shield 1011 is shaped like a shield. One end of the shield 1011 away from the inner wall of the drive slot 101 is fixedly connected to the clamping plate 2. When the two clamping plates 2 are in contact with each other, the two shields 1011 together cover the bidirectional lead screw 31.

[0040] When the base 1 is not supporting the wind turbine tower, the drive assembly 3 drives the two clamps 2 to fit together. At this time, the two shields 1011 are fully extended and cover the outer surface of the bidirectional lead screw 31, which prevents the bidirectional lead screw 31 from being corroded by the sea air when it is idle, thus ensuring the smooth operation of the drive assembly 3.

[0041] Reference Figure 2 and Figure 4 Two clamping plates 2 are fixedly connected to opposing surfaces with buffer airbags 6. The buffer airbags 6 are sleeved on the outer surface of the support cylinder 41. An inflation component 7 for inflating the buffer airbags 6 is provided on the base 1. A groove 103 is provided on the base 1. The groove 103 is located between the sliding groove 102 and the driving groove 101. Multiple pressure plates 71 are slidably connected in the groove 103 along the width direction of the base 1. An inflatable airbag 72 corresponding to each of the multiple pressure plates 71 is fixedly connected to the inner bottom wall of the groove 103. The inflatable airbag 72 is an elastic airbag. Multiple inflatable airbags 72 are connected through a connecting pipe 73 (not shown in the figure). One of the inflatable airbags 72 is connected to an air supply pipe 74 corresponding to each of the two buffer airbags 6. The air supply pipe 74 is a corrugated pipe and is connected to the corresponding buffer airbag 6.

[0042] After the wind turbine tower section is placed on the base 1, the weight of the section itself pushes the pressure plate 71 toward the inflatable airbag 72. The inflatable airbag 72 is continuously squeezed by the pressure plate 71. As the volume of the inflatable airbag 72 decreases, the gas inside enters the buffer airbag 6 through the connecting pipe 73 and the air supply pipe 74, causing the buffer airbag 6 to gradually inflate. When the buffer airbag 6 is inflated, the drive assembly 3 moves through the drive clamp 2 to drive the buffer airbag 6 to abut against the outer end face of the tower. When the ship is rocking, the buffer airbag 6 and the rubber pad 431 can effectively absorb the impact force and prevent the wind turbine tower from being damaged by hard collisions. After the transportation is completed, the wind turbine tower is taken off the base 1 by a crane. The pressure on the pressure plate 71 disappears, and the inflatable airbag 72 recovers its deformation under its own elasticity. The gas in the buffer airbag 6 flows back to the inflatable airbag 72 through the air supply pipe 74 to provide cushioning support for the subsequent wind turbine tower.

[0043] When the base 1 is not supporting the wind turbine tower, the drive assembly 3 drives the two clamps 2 to fit together. At this time, the two shields 1011 are fully extended and cover the outer surface of the bidirectional lead screw 31, which prevents the bidirectional lead screw 31 from being corroded by the sea air when it is idle, thus ensuring the smooth operation of the drive assembly 3.

[0044] The implementation principle of the offshore transport support for wind turbine towers in this application embodiment is as follows: Before transportation, the wind turbine tower section is hoisted and placed on the base 1 by a crane. Then, the drive motor 33 is started. After the wind turbine section is placed on the base 1, the drive motor 33 drives the bidirectional lead screw 31 to rotate in the drive groove 101. Under the restriction of the sliding groove 102, the bidirectional lead screw 31 rotates and drives the two clamping plates 2 to move towards or relative to each other along the length direction of the bidirectional lead screw 31 until the opposite end faces of the clamping plates 2 abut against the outer end face of the section. At this time, the limit of different length sections in the length direction of the base 1 is realized.

[0045] After the clamping plate 2 abuts against the outer end face of the cylindrical section, the support cylinder 41 extends into the interior of the cylindrical section. At this time, the moving motor 51 is started, and the moving motor 51 drives the lead screw 52 to rotate. Since the driving block 53 cannot rotate due to the restriction of the fixed rod 42 and the limiting through groove 411, the rotation of the lead screw 52 drives the driving block 53 to move along the axis of the support cylinder 41. As the driving block 53 moves from the small diameter end to the large diameter end, the fixed rod 42 moves away from the lead screw 52 along the length direction of the limiting through groove 411. The height of the fixed rod 42 extending out of the limiting through groove 411 increases continuously, so that the fixed plate 43 gradually approaches the inner wall of the cylindrical section. When the rubber pad 431 on the fixed plate 43 abuts against the inner wall of the cylindrical section, the limitation of cylindrical sections with different cross-sectional sizes in the width direction of the base 1 is realized, thus finally realizing the fixation of wind turbine towers of different sizes on the base 1, improving the applicability of the wind turbine tower transport support.

[0046] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
