Description

Technical Field

[0001] The utility model relates to the technical field of offshore wind power, in particular to a reinforcement structure for an offshore wind power single pile. Background Art

[0002] Offshore wind power monopiles have the advantages of simple structure, clear force, simple construction and construction process, short construction period, and good economy. They are currently the most widely used wind power foundation type in offshore wind farms.

[0003] The bearing capacity of offshore wind turbine piles is greatly affected by the seabed geology and environmental water depth conditions. They are prone to tilting and bending deformation in deep water environments, so reinforced structures are needed to provide auxiliary support for offshore wind turbine piles.

[0004] A search revealed that in the patent publication number CN218204384U, an offshore wind power monopile fixing device, it is stated that "the utility model, through the provision of a verticality detector, uses an adjustment mechanism under the transmission of a driving mechanism to timely correct the tilt of the monopile body, thereby ensuring the verticality of the monopile body during installation and avoiding the problem of insufficient fixing strength on the seabed due to tilt of the monopile body, which would affect its future service life."

[0005] However, the above scheme still has certain shortcomings in actual use. In the above scheme, a driving mechanism is used to correct the tilt position of the single pile body. However, during the correction process, the tilt position is found in advance and then the single pile body is continuously hit by the knocking block, and the force of each impact of the knocking block needs to be controlled separately, resulting in a long time-consuming process of correcting the tilt of the single pile body, thereby extending the installation time of the offshore wind power monopile, and further reducing the installation efficiency of the offshore wind power monopile.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 The utility model discloses a reinforcement structure for an offshore wind power monopile, comprising a reinforcement mechanism 1 , wherein a monopile body 2 is movably plugged into the interior of the reinforcement mechanism 1 , and a support column 3 is provided on the outside of the reinforcement mechanism 1 .

[0023] The reinforcement mechanism 1 includes a reinforcement box 101 and a top cover 102. An extension opening 104 is provided inside the reinforcement box 101 and the top cover 102. An auxiliary ring 105 and two clamping structures 107 are provided inside the reinforcement box 101. The two clamping structures 107 are provided obliquely below the auxiliary ring 105.

[0024] The clamping structure 107 includes a drive box 108, and a linear motor 110 is provided on the inner wall of the drive box 108 through a drive frame 109. The movable end of the linear motor 110 is fixedly connected to a drive rack 111, and a follower gear 112 is engaged with the outer side of the drive rack 111. A passive rack 113 is engaged with the other side of the follower gear 112. The bottom end of the follower gear 112 is rotatably connected to the inner wall of the drive box 108 through a bearing, and the passive rack 113 is slidably connected to the inner wall of the drive box 108 through a slide rod 114. A clamping ring 115 is fixedly installed at the bending part of the passive rack 113, and the clamping ring 115 extends to the outside of the drive box 108.

[0025] By providing the reinforcement mechanism 1, the lifting rod 106 inside the reinforcement box 101 can be used to provide auxiliary support to the monopile body 2 inside the extension opening 104 through the auxiliary ring 105, and then the clamping structure 107 can be used to clamp the monopile body 2 in a closed manner, so that the monopile body 2 is in a clamped state, so that the monopile body 2 can be vertically inserted into the seabed in a vertical state, thereby ensuring the verticality of the monopile body 2 during installation, thereby avoiding the problem of insufficient fixing strength of the monopile body 2 on the seabed due to tilt, which affects the future service life.

[0026] Specifically, an external connecting ring 103 is provided on the outer side of the reinforcement box 101 , and the support column 3 is located inside the external connecting ring 103 .

[0027] In this embodiment, the support column 3 is connected to the external ring 103, and then the support column 3 is driven into the seabed by hammering.

[0028] Specifically, a verticality detector 117 is fixedly installed on the outer side of the reinforcement box 101 .

[0029] In this embodiment, the horizontal state of the reinforcement box 101 is monitored in real time by a verticality detector 117 .

[0030] Specifically, a lifting rod 106 is fixedly installed at the bottom end of the auxiliary ring 105 , and the bottom end of the lifting rod 106 is fixedly connected to the inner wall of the reinforcement box 101 . The auxiliary ring 105 is located above the extension opening 104 inside the reinforcement box 101 .

[0031] In this embodiment, the lifting rod 106 can be used to form a gap between the auxiliary ring 105 and the extension opening 104 inside the reinforcement box 101, and the clamping ring 115 can clamp the monopile body 2 through the gap.

[0032] Specifically, contact balls 116 are provided inside the clamping ring 115 , and the clamping ring 115 overlaps with the surface of the monopile body 2 through the contact balls 116 .

[0033] In this embodiment, since the clamping ring 115 is connected to the monopile body 2 through the contact ball 116, the clamping ring 115 and the monopile body 2 are connected in a sliding manner, so that the monopile body 2 can be normally connected to the seabed by hammering.

[0034] When in use, first connect the support column 3 to the external ring 103, then sink the support column 3 into the seabed by hammering, and then use the verticality detector 117 to monitor the horizontal state of the reinforcement box 101 in real time;

[0035] Then, the monopile body 2 to be fixed is inserted into the reinforcement box 101, so that the monopile body 2 passes through the extension opening 104 of the top cover 102, the auxiliary ring 105, and the extension opening 104 inside the reinforcement box 101 in sequence, so that the monopile body 2 is confined between the two extension openings 104 and the auxiliary ring 105;

[0036] Then, the clamping structure 107 is started, causing the linear motor 110 inside the drive box 108 to start running, prompting the linear motor 110 to start driving the driving rack 111 to slide horizontally, so that the movement of the driving rack 111 drives the follower gear 112 to engage and rotate, and the rotation of the follower gear 112 drives the passive rack 113 to slide along the direction of the slide rod 114, prompting the passive rack 113 to drive the clamping ring 115 to gradually insert into the gap formed between the auxiliary ring 105 and the lower extension opening 104, so that the two clamping rings 115 jointly clamp the single pile body 2 in a closed manner;

[0037] Furthermore, since the clamping ring 115 is connected to the monopile body 2 via the contact balls 116 , the clamping ring 115 and the monopile body 2 are in a sliding connection, so that the monopile body 2 can be normally connected to the seabed by hammering.

[0038] To sum up, the offshore wind power single pile reinforcement structure, by setting up a reinforcement mechanism 1, uses the lifting rod 106 inside the reinforcement box 101 to auxiliary support the single pile body 2 inside the extension opening 104 through the auxiliary ring 105, and then cooperates with the clamping structure 107 to perform a closing clamping on the single pile body 2, so that the single pile body 2 is in a clamped state, causing the single pile body 2 to be vertically inserted into the seabed in a vertical state, thereby ensuring the verticality of the single pile body 2 during installation, and thus avoiding the problem of insufficient fixing strength of the single pile body 2 on the seabed due to tilt, which affects the future service life.

[0039] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
