[0015] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0016] See also Figure 1-7 As shown in the figure, this embodiment provides an offshore wind power tower installation auxiliary device, such as Figure 1 As shown, it includes a first docking mechanism 1, the bottom of which is provided with a supporting mechanism 2. Figure 5-6 As shown, the first docking mechanism 1 includes two first cover cylinders 101, the top surfaces of the two first cover cylinders 101 are fixedly connected to the first supporting platform 102, and the two sides of the two first cover cylinders 101 are fixedly connected to the first connecting plate 103, and the two first cover cylinders 101 and the first supporting platform 102 can be enclosed into a columnar shape by the first connecting plate 103.

[0017] Specifically, the two first cover cylinders 101 and the first supporting platforms 102 are both semicircular in shape, and the two first cover cylinders 101 and their corresponding first supporting platforms 102 can be spliced ​​together to form a cylindrical shape, and through the first connecting plates 103 that are spliced ​​together and then locked together through positioning bolts, the two first cover cylinders 101 and the corresponding first supporting platforms 102 can be enclosed in a fixed columnar shape, so that they can be easily disassembled and assembled from the outer wall of the wind turbine tower for use.

[0018] At the same time, combined Figure 7 As shown, a plurality of first through holes 104 are provided on the outer walls of the two first cover cylinders 101, and a connecting rod 105 is slidably connected in each of the plurality of first through holes 104, and a locking arm 106 is provided at one end of the plurality of connecting rods 105 extending out of the outer wall of the first cover cylinder 101, and the lower end of the locking arm 106 is rotatably connected to the connecting rod 105, and a support frame 107 is fixedly connected to the outer wall of the first cover cylinder 101, and the middle part of the locking arm 106 is placed on the support frame 107 and is rotatably connected. When the connecting rod 105 moves outward, it can drive the upper end of the locking arm 106 to be pressed against the first supporting platform 102.

[0019] Specifically, when in use, by moving the connecting rod 105 toward the outer wall of the first cover cylinder 101, the locking arm 106 can be pushed to rotate around the connection with the support frame 107, and then the multiple locking arms 106 can be synchronously moved toward the center of the circle close to the first supporting platform 102. Therefore, when the flange is placed on the top of the first supporting platform 102, it can be limited and supported on the outer periphery of the flange by multiple locking arms 106, thereby completing the limiting work of the flange.

[0020] At the same time, combined Figure 6-7 As shown, the support mechanism 2 includes a support tube 21 fixedly mounted on the bottom of the first cover tube 101. The support tube 21 and the first cover tube 101 are arranged in a detachable state. The top of the support tube 21 is fixedly connected to a second supporting platform 210 extending into the first cover tube 101. The outer wall of the second supporting platform 210 is rotatably mounted with a sliding assembly, which is used to drive the multiple connecting rods 105 to move outward. Specifically, when in use, the first tower is placed inside the columnar body enclosed by the two first cover tubes 101 and placed on top of the second supporting platform 210.

[0021] Further, refer to Figure 7 As shown, the sliding assembly includes a steering sleeve 22 rotatably mounted on the outer wall of the second supporting platform 210, and a disc 23 is fixedly connected to the top of the steering sleeve 22. The outer wall of the disc 23 is annularly fixed with multiple guide protrusions 24 in an equidistant state. Multiple connecting rods 105 are slidably mounted on the outer walls of the disc 23 and the guide protrusions 24, and one side of the multiple guide protrusions 24 is fixedly connected to an anti-slip block 25. Specifically, under normal conditions, the connecting rod 105 slides on the outer wall of the disc 23. When the disc 23 drives the multiple guide protrusions 24 to rotate, so that the multiple connecting rods 105 gradually slide toward the outer wall of the guide protrusion 24, the multiple connecting rods 105 can be gradually moved toward the outer wall of the first cover tube 101. Combined with the setting of the anti-slip block 25, it is used to limit the moving range of the connecting rod 105. When the connecting rod 105 needs to be restored to its original position, the control disc 23 is reversed as a whole.

[0022] Furthermore, a slide groove 26 is provided on the outer wall of the supporting cylinder 21, and a transmission frame 27 fixedly connected to the steering sleeve 22 is slidably connected in the slide groove 26. A first electric drive rod 29 is rotatably installed on the top of the supporting cylinder 21, and the sleeve of the first electric drive rod 29 is provided with an adjustment frame 28, and the transmission frame 27 is slidably installed inside the adjustment frame 28. Specifically, in actual use, the first electric drive rod 29 is driven by the motor to rotate so that the adjustment frame 28 drives the transmission frame 27 to move, so that when the steering sleeve 22 drives the disc 23 to rotate counterclockwise as a whole, the guide protrusion 24 can gradually come into contact with the connecting rod 105 and push the connecting rod 105 to move toward the outer wall of the first cover cylinder 101, thereby causing multiple corresponding locking arms 106 to deflect, and then causing the tops of multiple locking arms 106 to synchronously displace and press against the outer wall of the flange placed on the top of the first supporting platform 102.

[0023] Furthermore, the multiple connecting rods 105 and the locking arms 106 are arranged in a one-to-one correspondence, and the multiple locking arms 106 are arranged in a circular shape and equidistantly in sequence around the outer circumferential surface of the first cover tube 101, and the top heights of the multiple locking arms 106 are higher than the horizontal height of the first supporting platform 102.

[0024] Specifically, the purpose of such a setting is to enable the flange to be placed on the top of the first supporting platform 102, to be synchronously limited by the multiple locking arms 106, so that the flange and the first supporting platform 102 are kept in a concentric state and limited, thereby synchronously making the flange and the first tower placed inside the first cover 101 and keep them in a concentric state, making the connection and limiting work between the flange and the first tower more convenient.

[0025] It should be noted that when installing the first tower and the flange, it is difficult to keep the first tower and the flange concentric due to the turbulent sea environment. Therefore, further design can be made, as detailed below:

[0026] It also includes a second docking mechanism 3, which includes a second electric drive rod 31 rotatably installed inside the second supporting platform 210, and the outer wall of the second electric drive rod 31 is engaged with a threaded sleeve 32. The outer wall of the threaded sleeve 32 is hinged with multiple first support rods 33, and one end of each of the multiple first support rods 33 is hinged with a second support rod 34 hinged to the second supporting platform 210, and the tops of the multiple second support rods 34 are rotatably connected with a gasket 35, and the second electric drive rod 31 can drive the gasket 35 to expand outward.

[0027] Specifically, when in use, the first tower is placed inside a columnar body surrounded by two first cover tubes 101 and placed on top of the second supporting platform 210. At this time, the second electric drive rod 31 is driven to rotate, so that the multiple first support rods 33 and the second support rods 34 are expanded and deflected until the multiple gaskets 35 are pressed against the inner wall of the first tower. This can keep the first tower and the flange in a concentric state, making the subsequent installation of the flange and the first tower more convenient and easier to operate. There is no need to adjust the position of the tower and the flange back and forth, which is more conducive to improving work efficiency.

[0028] It should be noted that, when installing the first tower and the flange, it is difficult to keep the first tower and the second tower in a concentric state due to the turbulent environment at sea. A third docking mechanism 4 can also be specifically designed, as detailed below:

[0029] More preferably, referring to Figure 3-4 As shown, a plurality of positioning holes 108 are provided on the top of the first supporting platform 102, and a third docking mechanism 4 is inserted into the top of the first docking mechanism 1, and the third docking mechanism 4 includes a second cover tube 41 arranged on the top of the first supporting platform 102, and a third cover tube 42 is slidably installed on the top of the second cover tube 41. The second cover tube 41 and the third cover tube 42 are both semicircular in shape, and the number of the second cover tube 41 and the third cover tube 42 is two, and a second connecting plate 43 is fixedly installed on both sides of the two second cover tubes 41 and the third cover tube 42. Specifically, in actual use, the two second cover tubes 41 and the third cover tube 42 are spliced ​​and fixed to each other through corresponding second connecting plates 43 to form two annular bodies that are sleeved on the outer periphery of the second tower.

[0030] In addition, a plurality of positioning rods 44 are fixedly installed at the bottom of the two second cover tubes 41, and the plurality of positioning rods 44 are inserted into the positioning holes 108. Specifically, the purpose of such a setting is to keep the second cover tube 41 and the first supporting platform 102 connected in a fixed state, so that after the first tower tube and the flange are concentrically limited by the first docking mechanism 1 and the second docking mechanism 3, the second tower tube is kept concentrically set on the top of the flange through the setting of the third docking mechanism 4.

[0031] At the same time, a plurality of through slots 45 are provided on the outer wall of the third cover barrel 42, and a limit frame 46 is rotatably installed in each of the through slots 45, and a second pressure plate 47 rotatably connected to the second cover barrel 41 is slidably installed in each of the limit frames 46. Specifically, when in use, by rotating the third cover barrel 42, the second pressure plate 47 can be rotated as a whole around the connection with the first docking mechanism 1, and then slide inside the limit frame 46, and the length of the second pressure plate 47 extending into the inside of the third cover barrel 42 is changed. Then, combined with the arrangement of the plurality of second pressure plates 47, after the second tower barrel is placed inside the second cover barrel 41 and the third cover barrel 42, it can be simultaneously limited and pressed by the plurality of second pressure plates 47, thereby maintaining the limiting stability of the second tower barrel.

[0032] Among them, one side of the third cover cylinder 42 is rotatably connected to a rotating block 49, and one side of the second cover cylinder 41 is rotatably installed with a third electric drive rod 48, and the rotating block 49 is engaged with the outer wall of the third electric drive rod 48. Specifically, the purpose of such a setting is that when the third electric drive rod 48 rotates, the rotating block 49 can drive the third cover cylinder 42 as a whole to move on its outer wall, so that the third cover cylinder 42 as a whole can be deflected and adjusted at the top of the second cover cylinder 41, thereby realizing synchronous driving of multiple second pressure plates 47 to deflect and displace, so that the distance between the multiple second pressure plates 47 can be adjusted according to the outer circumferential diameter length of the second tower. Therefore, combined with the setting of the second docking mechanism 3, even if the circumferential diameter lengths of the two interconnected towers are inconsistent, the distance between the multiple second pressure plates 47 and the multiple second support rods 34 and the gaskets 35 can be conveniently adjusted by self-adjusting the distance between the multiple second pressure plates 47 and the multiple second support rods 34 and the gaskets 35. While limiting and fixing the two towers, the two towers are always kept in a concentric state, thereby making the mutual positioning of the two towers faster and more convenient, and more convenient for practical use.

[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
