[0033] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0034] Embodiment one: please refer to Figures 1-6 and Figure 9 As shown in the drawings, in order to solve the problems that the existing technology is difficult to adapt to the precise vertical installation of complex seabed topography and cannot be multi-directionally self-adaptive to resist sea wave impact, the following solutions can be used:

[0035] A multi-floating-cylinder anti-tilting offshore wind power jacket structure in the embodiment includes a plurality of bottom-opened suction cylinders 1, a suction hole for negative pressure extraction installation is arranged on one side of the top of the suction cylinder 1, a reinforced stringer 11 is fixedly connected to the top of the suction cylinder 1, a reinforced brace 12 is fixedly connected between adjacent two groups of reinforced stringers 11, the outer side of the plurality of reinforced stringers 11 is provided with a floating cylinder anti-tilting mechanism 2 for multi-directional self-adaptive resistance to sea wave impact on the jacket, and the inside of the suction cylinder 1 is provided with a reinforcing mechanism 3 for reinforcing the stable installation of the suction cylinder 1;

[0036] The floating cylinder anti-tilting mechanism 2 comprises a mounting ring 21 and a plurality of floating cylinders 22 fixedly connected to the outer side wall of the mounting ring 21, and the mounting ring 21 and the plurality of floating cylinders 22 are arranged to realize the anti-tilting lowering of the jacket platform and, when facing the impact of a rising sea wave, the impact side floating cylinder 22 is lifted by the sea wave to cause the mounting ring 21 to tilt, and the descending floating force of the impact side back floating cylinder 22 is used to offset the tilting force acting on the mounting ring 21, so as to reduce the height of the sea wave and the impact force on the jacket platform, and the outer side wall of the floating cylinder 22 is fixedly connected with an Ω-shaped rib plate 23 fixedly connected with the mounting ring 21, and the Ω-shaped rib plate 23 is arranged to assist in increasing the connection stability between the floating cylinder 22 and the mounting ring 21.

[0037] The reinforced stringer 11 is welded with a sliding rod 13 for mounting the floating cylinder anti-tilting mechanism 2, and the sliding rod 13 is fixedly connected with a sliding sleeve 24, and the two sides of the sliding sleeve 24 are fixedly connected with a sleeve rod 25 and a connecting rod 26, and the sleeve rod 25 and the connecting rod 26 between the adjacent two groups of sliding sleeves 24 are matched to assist the reinforced support rod 12 and improve the connection stability between the plurality of reinforced stringers 11.

[0038] The sleeve rod 25 and the corresponding connecting rod 26 between the adjacent reinforced stringers 11 are slidingly connected, a plurality of fixing holes are equidistantly and penetratingly arranged on the connecting rod 26, and a connecting pin is arranged on the sleeve rod 25 and inserted into the corresponding fixing hole, the connecting pin on the sleeve rod 25 is inserted into the fixing hole on the connecting rod 26 after the jacket platform is installed, the installation height of the mounting ring 21 is fixed, and a plurality of connecting pins can be arranged to increase the connection stability of the sleeve rod 25 and the connecting rod 26.

[0039] A pipe sleeve 27 is arranged between the mounting ring 21 and the corresponding sliding sleeve 24, a limit block 29 is slidingly and fixedly connected with the pipe sleeve 27 through a tension spring 28, the limit block 29 and the pipe sleeve 27 are sealingly and slidingly connected to avoid corrosion of the tension spring 28 caused by contact with seawater, and a pull rod 210 is movably and penetratingly arranged on one side of the limit block 29 and extends to the outside of the pipe sleeve 27.

[0040] During the lowering and installation of the jacket platform, the floating cylinder 22 contacts the sea surface and generates a floating force, the mounting ring 21 cooperates with the sleeve rod 25 and the connecting rod 26 to carry the plurality of sliding sleeves 24 to synchronously and relatively ascend on the reinforced stringer 11, and the tension spring 28 in each pipe sleeve 27 is stretched, the floating force and the stretching force of the tension spring 28 are used to assist the jacket platform to perform the anti-tilting lowering movement, so that the jacket platform can gradually adjust the posture under the action of the floating force and the tension spring 28, and the vertical installation is realized.

[0041] The free end of the pull rod 210 and the pipe sleeve 27 are fixedly connected with ball heads, the mounting ring 21 and the sliding sleeve 24 are fixedly connected with ball socket seats movably installed with the corresponding ball heads, when the sea waves surge from a direction, the buoyancy cylinder 22 in the direction will rise, through the connection of the ball head and the ball socket seat, the mounting ring 21 is inclined, and the buoyancy cylinder 22 on the back of the impact side is pressed below the sea surface;

[0042] Due to the increase of the water volume pushed away by the pressed buoyancy cylinder 22, the buoyancy is significantly increased, the buoyancy acts upward on the mounting ring 21, offsets the tilting force generated by the sea wave impact, assists the horizontal reset of the mounting ring 21, reduces the height of the sea wave, significantly reduces the impact force of the sea wave on the guide pipe support, avoids the inclination of the offshore wind guide pipe support, and greatly improves the safety and stability of the guide pipe support in complex sea conditions.

[0043] The cross section of the Ω-shaped rib plate 23 is funnel-shaped, and the top area of the Ω-shaped rib plate 23 is larger than the bottom area. The funnel-shaped Ω-shaped rib plate 23 can significantly reduce the self-gravity of the Ω-shaped rib plate 23, and assist the lifting effect of the corresponding buoyancy cylinder 22 when the buoyancy cylinder 22 is impacted by the surging sea wave;

[0044] A plurality of drainage holes are evenly arranged on the bottom of the Ω-shaped rib plate 23 along the periphery of the buoyancy cylinder 22, for draining the excessive seawater entering between the Ω-shaped rib plate 23 and the buoyancy cylinder 22. The inside of the buoyancy cylinder 22 is fixedly connected with cross-shaped reinforcing rib plates for increasing the compression strength of the buoyancy cylinder 22 itself, avoiding deformation or damage of the buoyancy cylinder 22 due to the large buoyancy when the mounting ring 21 is inclined downward, and thereby improving the service life of the device.

[0045] The top of the plurality of groups of reinforced stringers 11 is fixedly connected to the same transition section 14, and the top of the transition section 14 is fixedly connected with an upper platform 15 having a fence installed around the periphery.

[0046] The reinforced stringers 11 and the reinforced struts 12 are composed of steel cylinders 16 and grid level reinforcements. The grid level reinforcement structure can uniformly disperse the stress received by the reinforced stringers 11 and the reinforced struts 12, avoid local stress concentration, avoid the problem of local buckling of the thin-walled structure from the inside, improve the buckling resistance of the reinforced stringers 11 and the reinforced struts 12, and thereby realize the effects of improving the bearing capacity of the stringers and struts of the guide pipe support, standardizing the design, and reducing the weight.

[0047] The grid level reinforcement comprises a plurality of annular main reinforcements 17 fixedly connected on the inner wall of the steel cylinder 16, and a plurality of annular secondary reinforcements 18 arranged between adjacent two groups of annular main reinforcements 17, a plurality of longitudinal main reinforcements 19 arranged in an annular array on the inner wall of the steel cylinder 16, and a plurality of longitudinal secondary reinforcements 110 arranged between adjacent longitudinal main reinforcements 19, the longitudinal secondary reinforcements 110 and the annular secondary reinforcements 18 are arranged in the grids of the longitudinal main reinforcements 19 and the annular main reinforcements 17 to form smaller grid cells, thereby further improving the buckling resistance.

[0048] Embodiment two: please refer to Figure 7 With Figure 8 As shown in the figure, for the problem that the multi-buoy structure affects the stability of the installation of the suction cylinder, the following solutions can be used to solve the problem:

[0049] The reinforcing mechanism 3 in this embodiment comprises movable plates 31 arranged inside the suction cylinder 1 on both sides, and a plurality of auxiliary insertion rods 32 are fixedly connected to one side of the movable plates 31 and slide with the suction cylinder 1. After the suction cylinder 1 stops sinking, the two groups of movable plates 31 carry the auxiliary insertion rods 32 away from the movement, prompting the end of the auxiliary insertion rods 32 to extend out of the suction cylinder 1 and insert into the seabed, thereby assisting the installation of the suction cylinder 1, further enhancing the connection strength between the suction cylinder 1 and the seabed, and improving the stability of the installation of the jacket.

[0050] The movable plates 31 are slidably connected between the movable plates 31, and a plurality of inclined grooves 34 are equally arranged on the inner walls of the two sides of the movable plates 31. A guide column 35 is fixedly connected to the movable plate 33 and slides in the corresponding inclined groove 34. The movable plate 33 moves upward relative to the suction cylinder 1, and the guide column 35 slides in the corresponding inclined groove 34, thereby pushing the two groups of movable plates 31 away from the movement. A reinforcing frame 36 is fixedly connected to the movable plate 33 and slides with the inner wall of the suction cylinder 1, which is used to cooperate with the movable plate 33, the guide column 35, the inclined groove 34, and the movable plate 31 to increase the buckling resistance of the cylinder wall of the suction cylinder 1.

[0051] The top of the reinforcing frame 36 is fixedly connected to a plugging column 37 matched with the suction hole of the suction cylinder 1. The suction cylinder 1 is sunk to a certain depth in the seabed by using the weight, and then continues to sink by extracting negative pressure, until the material in the suction cylinder 1 touches the top of the reinforcing frame 33, causing the reinforcing frame 33 to move upward relative to the suction cylinder 1, thereby assisting the plugging column 37 to insert into the suction hole of the suction cylinder 1, causing the suction cylinder 1 to stop sinking, and continuing the negative pressure extraction process, causing the plugging column 37 to continuously move upward with the reinforcing frame 33.

[0052] By injecting water into the suction hole of the suction cylinder 1, the plugging column 37 is pushed to move downward, combined with the guide column 35 and the corresponding inclined groove 34, to cause the two groups of movable plates 31 to move relative to each other, so that the end of the auxiliary insertion rod 32 is retracted into the side wall of the suction cylinder 1, and then the water injection is continued to cooperate with the crane to recover the suction cylinder 1.

[0053] Embodiment three: please refer to Figures 1-9 As shown, the application also proposes a method for using the offshore wind power jacket structure with multiple floating cylinders and anti-tilting, comprising the following steps:

[0054] Step one: the wind power jacket is lowered to the shallow sea installation area by the crane, and the suction cylinder 1 is sunk to a certain depth of the seabed by its own weight, and then the negative pressure is continuously extracted for further sinking treatment until the material in the suction cylinder 1 touches the top of the movable frame 33, causing it to rise relative to the suction cylinder 1, and the auxiliary plugging column 37 is inserted into the suction hole of the suction cylinder 1, causing the suction cylinder 1 to stop sinking;

[0055] Then continue the negative pressure extraction process, causing the plugging column 37 to continuously rise with the movable frame 33, and in the rising process, the two groups of movable plates 31 are pushed away from the movement by the guide column 35 in the corresponding inclined groove 34, prompting the auxiliary insertion rod 32 to extend from the inside of the suction cylinder 1 and insert into the seabed, which helps to strengthen the installation of the suction cylinder 1;

[0056] Step two: when the jacket is lowered, the multiple floating cylinders 22 on the installation ring 21 contact the sea surface, and in the lowering process, the installation ring 21 cooperates with the sleeve rod 25 and the connecting rod 26 to carry multiple sliding sleeves 24 to rise relative to the reinforced chord 11, and in combination with the stretching of the tension spring 28 in each pipe sleeve 27, it assists the jacket to descend in an anti-tilting manner, and installs the jacket vertically on the uneven seabed;

[0057] Step three: after the jacket is installed, the connecting pin on the sleeve rod 25 is inserted into the fixed hole on the corresponding connecting rod 26 to fix the installation height of the installation ring 21. When the rising sea wave impacts the jacket, the sea wave simultaneously pushes the floating cylinder 22 in the corresponding direction to rise, and in combination with the setting of the ball head and the socket seat, the installation ring 21 is tilted, and the floating cylinder 22 on the impact side of the back is pressed below the sea surface, and the floating force of the impact side of the back is used to offset the tilting force of the installation ring 21, which helps the installation ring 21 to reset horizontally, so as to reduce the height of the sea wave and in turn reduce the impact force on the jacket;

[0058] Step four: when the suction cylinder 1 is recycled, water is injected into the suction hole of the suction cylinder 1 to push the plugging column 37 to descend, in combination with the guide column 35 and the corresponding inclined groove 34, to cause the two groups of movable plates 31 to move relative to each other, so that the end of the auxiliary insertion rod 32 is collected into the side wall of the suction cylinder 1, and then the water injection is continued to recycle the suction cylinder 1 with the crane.

[0059] The above merely describes preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art, according to the technical solution and inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
