[0029] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0030] An offshore work platform 10 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0031] Reference Figure 1-Figure 4 According to the first aspect of the utility model, the offshore operating platform 10 includes: a base station platform 1, piles and spiral anchor plates, and the base station platform 1 is used to support the operating equipment 20; for example, the operating equipment 20 can be a booster station, the operating equipment 20 can also be an offshore wind power conversion system, and the operating equipment 20 can also be a seabed oil extraction system.

[0032] There are multiple piles, each of which is movably arranged on the base station platform 1 in the up-down direction, and each pile is suitable for penetrating into the seabed 300 to anchor the base station platform 1. For example, the pile can be slidably connected to the base station platform 1, and the pile can be driven to move up and down relative to the base station platform 1 by a driving mechanism, so as to achieve the purpose of the pile moving up and down relative to the base station platform 1; for another example, the pile can also be threadedly connected to the base station platform 1, and the pile can be driven to rotate relative to the base station platform 1 by a driving mechanism, so as to achieve the purpose of the pile moving up and down relative to the base station platform 1.

[0033] By setting a plurality of piles to anchor the base station platform 1, the plurality of piles provide a relatively stable support to the base station platform 1, which can improve the anti-overturning capability of the offshore operation platform 10 and meet the use requirements of the operation equipment 20. At the same time, the plurality of piles can improve the bearing capacity of the offshore operation platform 10, slow down the sinking speed of the offshore operation platform 10, so that the offshore operation platform 10 can reliably support the large-tonnage operation equipment 20, and improve the reliability of the offshore operation platform 10.

[0034] In the description of the present invention, it should be understood that the “plurality” mentioned herein refers to “two” or “more than two”.

[0035] Each pile column can rotate along its axis, and a spiral anchor plate is connected to the radial outer side of each pile column, and the rotation direction of the spiral anchor plate on at least one pile column is opposite to the rotation direction of the spiral anchor plates on the remaining pile columns. For example, the plurality of pile columns may include a first pile column 21 and a second pile column 22, the spiral anchor plate connected to the first pile column 21 is a first spiral anchor plate 31, and the rotation direction of the first spiral anchor plate 31 is left-handed, and the spiral anchor plate connected to the second pile column 22 is a second spiral anchor plate 32, and the rotation direction of the second spiral anchor plate 32 is right-handed. There may be a plurality of first pile columns 21, and / or a plurality of second pile columns 22.

[0036] It should be understood that the method for determining the rotation direction of the spiral anchor piece is: in the direction from top to bottom, if the spiral anchor piece rotates counterclockwise, then the rotation direction of the spiral anchor piece is left-handed; if the spiral anchor piece rotates clockwise, then the rotation direction of the spiral anchor piece is right-handed.

[0037] When anchoring the offshore work platform 10, the offshore work platform 10 can be transported to a preset position first, and then the piles can be driven downward and rotated. For example, the first pile 21 can be driven counterclockwise and the second pile 22 can be driven clockwise to penetrate the piles and the spiral anchor plates into the seabed 300. When the piles reach the preset depth, the driving of the piles is stopped to complete the anchoring of the offshore work platform 10.

[0038] The operating equipment 20 can be built on the base station platform 1 before the offshore operating platform 10 is transported to a preset position. For example, the operating equipment 20 can be built on the base station platform 1 on land to reduce the difficulty of offshore operations, improve the building efficiency, and reduce the construction cost. The operating equipment 20 can also be built on the base station platform 1 after the offshore operating platform 10 is anchored and stabilized to reduce the transportation difficulty and transportation cost.

[0039] By connecting a spiral anchor plate on the radial outer side of the pile column, the anchoring force between the pile column and the seabed 300 can be improved, the bearing capacity of the pile column can be improved, and the sinking speed of the offshore work platform 10 can be slowed down, so that the offshore work platform 10 can reliably support large-tonnage work equipment 20, thereby improving the reliability of the offshore work platform 10.

[0040] By setting the spiral anchor plates of at least one pile column to have a different rotation direction from the spiral anchor plates of the remaining pile columns, when the pile column is penetrated into the seabed 300, it is necessary to drive the at least one pile column and the remaining pile columns in opposite directions, so that the torsional force generated by the at least one pile column and the torsional force generated by the remaining pile columns offset each other, thereby reducing the amplitude of the pile column shaking, preventing the pile column from shaking too much and causing the soil around the pile column to loosen, making the anchoring between the pile column and the seabed 300 more secure, and improving the reliability of the offshore work platform 10.

[0041] At the same time, since the rotation direction of the spiral anchor plates of at least one pile column is set to be different from that of the spiral anchor plates of the remaining pile columns, the amplitude of the pile column shaking is reduced, so that the shaking amplitude of the base station platform 1 during the anchoring process is smaller, and the shaking amplitude of the operating equipment 20 on the base station platform 1 is smaller. It is unnecessary to set up equipment for stabilizing the base station platform 1, and it is unnecessary to set up equipment for stabilizing the operating equipment 20, thereby reducing the difficulty of operation during the anchoring process of the offshore operating platform 10 and improving the efficiency of the anchoring of the offshore operating platform 10.

[0042] According to the offshore working platform 10 of the utility model, by setting rotating anchor plates on piles, and setting the rotation direction of the rotating anchor plates on at least one pile to be opposite to the rotation direction of the rotating anchor plates on the other piles, when the piles are screwed into the seabed 300, the piles with different rotation directions rotate in opposite directions, which can offset part of the torsional force, so that multiple piles can penetrate downward into the seabed 300 more stably, preventing the piles from shaking too much and causing the soil around the piles to loosen, so that the piles are reliably anchored to the seabed 300, thereby improving the reliability of the offshore working platform 10.

[0043] Reference Figure 4 According to some embodiments of the utility model, the offshore work platform 10 further includes: a floating platform, which is connected to the base station platform 1 and is suitable for floating on the water surface. For example, the floating platform can be an airbag or a raft. The floating platform can float the base station platform 1. When transporting the offshore work platform 10, the offshore work platform 10 can be placed in the seawater. The offshore work platform 10 is towed by the towing boat 400, so there is no need to transfer the offshore work platform 10 to the towing boat 400, and there is no need to hoist the offshore work platform 10 from the towing boat 400 to a preset position, which facilitates the transportation of the offshore work platform 10 and reduces the cost of transporting the offshore work platform 10.

[0044] Reference Figure 1 According to some embodiments of the utility model, each pile is connected with a plurality of spiral anchor plates. This can further improve the anchoring force between the pile and the seabed 300, more reliably improve the bearing capacity of the pile, effectively slow down the sinking speed of the offshore work platform 10, so that the offshore work platform 10 can reliably support larger tonnage work equipment 20, and improve the reliability of the offshore work platform 10.

[0045] Reference Figure 1 According to some embodiments of the present invention, the ratio of the diameter of the spiral anchor sheet to the diameter of the pile column is greater than or equal to 1.5 and less than or equal to 3.5. For example, the ratio of the diameter of the spiral anchor sheet to the diameter of the pile column can be 1.5, 1.6, 1.7, 1.8, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3.0, 3.1, 3.2, 3.3, 3.4, 3.5.

[0046] The larger the ratio of the diameter of the spiral anchor piece to the diameter of the pile column, the greater the improvement of the anchoring effect between the pile column and the seabed 300 by the spiral anchor piece; the smaller the ratio of the diameter of the spiral anchor piece to the diameter of the pile column, the easier it is for the spiral anchor piece to be screwed into the seabed 300. Setting the ratio of the diameter of the spiral anchor piece to the diameter of the pile column to be greater than or equal to 1.5 and less than or equal to 3.5 can achieve a better anchoring effect between the pile column and the seabed 300, and can also reduce the difficulty of penetrating the pile column into the seabed 300, thereby improving the anchoring efficiency of the offshore work platform 10.

[0047] Reference Figure 2 According to some embodiments of the utility model, a plurality of piles are arranged at intervals along the circumference of the base station platform 1, and the spiral anchors on two adjacent piles have opposite rotation directions. When anchoring the offshore operation platform 10, it is necessary to rotate the two adjacent piles in different directions so as to screw the spiral anchors on the two piles into the seabed 300. In this process, the torsional forces generated by the two adjacent piles can be offset against each other, shortening the transmission distance of the torsional forces, so that the torsional forces can be quickly offset, and the shaking amplitude of the piles can be timely and effectively reduced.

[0048] Reference Figure 3 According to some embodiments of the present invention, a plurality of piles are arranged at intervals along the circumference of the base station platform 1, and the spiral anchors on the two diagonally arranged piles have opposite directions of rotation. That is, on the upper surface of the base station platform 1, the line between the two diagonally arranged piles passes through the center of the base station platform 1.

[0049] When anchoring the offshore operation platform 10, the two diagonally arranged piles need to be rotated in different directions so as to screw the spiral anchor plates on the two piles into the seabed 300. In this process, the torsional forces generated by the two diagonally arranged piles can offset each other. Since the connecting line between the two diagonally arranged piles passes through the center of the base station platform 1, the torsional forces generated by the two diagonally arranged piles are in opposite directions, which can more effectively eliminate the torsional force acting on the infrastructure platform, thereby more effectively reducing the shaking amplitude of the piles.

[0050] Reference Figure 1-Figure 3 In some embodiments of the present invention, the offshore work platform 10 further includes: a plurality of driving members 4, the number of the plurality of driving members 4 is the same as the number of piles and corresponds one to one, each driving member 4 is arranged on the base station platform 1, and each driving member 4 is used to drive the corresponding pile to rotate. For example, the driving member 4 can be a motor, the driving member 4 can also be a rotating cylinder, and the driving member 4 can also be a rotating oil cylinder. In this way, each driving member 4 can apply a larger driving force to the pile, so that the pile can be reliably screwed into the seabed 300, thereby improving the anchoring ability of the offshore work platform 10.

[0051] In some embodiments of the utility model, the offshore operation platform 10 further includes: a driving member 4 and a transmission assembly, wherein the driving member 4 is disposed on the base station platform 1, and the output shaft of the driving member 4 is connected to the transmission assembly, and the transmission assembly is connected to each pile column to drive each pile column to rotate. In this way, the driving member 4 can drive all the pile columns to rotate synchronously, so that the torsional force on each pile column is roughly equal, so that the torsional force applied to the base station platform 1 by two pile columns with opposite rotation directions of the spiral anchor plates can be effectively offset, and the amplitude of the shaking of the pile column is effectively reduced, so that the anchoring between the pile column and the seabed 300 is more secure, and the reliability of the offshore operation platform 10 is improved.

[0052] For example, the transmission assembly includes a driving gear, a driven gear and a transmission gear. Each pile column is provided with a driven gear, and the output shaft of the driving member 4 is provided with a driving gear. Each driven gear is meshed with the driving gear through the transmission gear to rotate synchronously under the drive of the driving gear.

[0053] For another example, the rotating assembly may include a driven pulley, a driving pulley and a belt, each pile is provided with a driven pulley, the output shaft of the driving member 4 is provided with a driving pulley, and each driven pulley is connected to the driving pulley through a belt so as to rotate synchronously under the drive of the driving pulley.

[0054] According to some embodiments of the present utility model, the offshore work platform 10 further includes: a locking mechanism, which is used to lock the pile column with the base station platform 1. For example, a locking hole is provided on the pile column, and a matching hole opposite to the locking hole is provided on the base station platform 1. The locking mechanism includes a locking pin, and when the pile column is penetrated to a preset depth in the seabed 300, the pile column and the base station platform 1 can be locked by inserting the locking pin into the locking hole and the matching hole.

[0055] When the pile is driven into the seabed 300 to a preset depth, the pile and the base station platform 1 can be locked by a locking mechanism to prevent the pile and the base station platform 1 from moving relative to each other, thereby preventing the base station platform 1 from being unstable and ultimately causing the risk of damage to the operating equipment 20. This ensures that the base station platform 1 is reliably connected to the pile, that the base station platform 1 is reliably fixed to the seabed 300, and that the operating equipment 20 on the base station platform 1 is reliably positioned.

[0056] Reference Figure 1-Figure 4 The offshore infrastructure 100 according to the second embodiment of the utility model includes: an offshore operation platform 10 and an operation device 20, wherein the offshore operation platform 10 is the offshore operation platform 10 according to the first embodiment of the utility model; and the operation device 20 is arranged on the offshore operation platform 10. For example, the operation device 20 may be a booster station, an offshore wind power conversion system, or a submarine oil production system.

[0057] According to the offshore infrastructure 100 of the present invention, by providing the above-mentioned offshore operating platform 10 , the offshore infrastructure 100 can be reliably anchored to the seabed 300 , thereby improving the reliability of the offshore infrastructure 100 .
