[0017] (III) Beneficial effects: Compared with the prior art, the present invention provides a wave compensation fixed support device for ship transportation of offshore wind power components, having the following beneficial effects: 1. For this wave compensation fixed support device for ship transportation of offshore wind power components, an installation space is opened downward on the deck, and by using the bottom and surrounding walls of the installation space, a hydraulic support rod responsible for lifting in the up and down direction, front and rear hydraulic pull rods responsible for ensuring stability in the front and rear directions, and left and right hydraulic pull rods responsible for ensuring stability in the left and right directions are connected and installed at the bottom of the placement plate. One end of each of these three hydraulic rods is connected to the placement plate, and the other end is connected to the lower surface and the four walls inside the installation space. Moreover, a hydraulic control system is installed in the hydraulic pull rods, which can flexibly change the telescopic amount of the hydraulic cylinder according to the influence of the waves on the platform, so as to adjust and balance the placement plate in six directions; and the present invention adopts the cooperation of the first hinge and the second hinge, the third hinge and the fourth hinge, and the fifth hinge and the sixth hinge with mutually perpendicular movement trajectories, so that on the basis of having their own telescopic directions, the hydraulic support rod, the front and rear hydraulic pull rods, and the left and right hydraulic pull rods also obtain four additional degrees of freedom of movement in different directions. This design can easily achieve multi-dimensional coordinated movement without complicating the structure, greatly improving the flexibility and adaptability of the device.

[0018] 2. The wave compensation fixed support device for ship transportation of offshore wind power components realizes the following functions through the coordinated use of counterweights, slide rails, ropes, pulley blocks and limit devices: When the placement board tilts due to wave influence, and the tilt amplitude is too large or the hydraulic system cannot adjust in time, the counterweight slides along the slide rail towards the lower side of the tilt under the action of gravity; As the counterweight slides, the rope is subjected to a tensile force along the direction of the slide rail, and since the distance between the counterweight and the high-end rope gradually increases, the angle between the rope and the counterweight gradually decreases, and the tensile force gradually increases; The rope passes through the fixed pulley, converting the tensile force in the tilt direction into a vertically downward tensile force, which exerts a downward pull on the high-end position of the placement board, thereby passively adjusting the telescopic state of the hydraulic rod; Compared with the traditional pure hydraulic compensation structure, this device realizes the passive compensation function and the controllability of the sliding range, and can maintain the stability of the platform when the active control system fails or the response is insufficient; At the same time, limit devices are provided at both ends of the slide rail to prevent the counterweight from sliding excessively, further enhancing the stability of the structure.

[0019] 3. The wave compensation fixed support device for ship transportation of offshore wind power components, through the coordinated use of stiffening rib structures, tension sensors and rolling bearings, can transmit signals to the hydraulic control system through the tension sensor when the tensile force of the rope is too large, so as to regulate the balance of the placement board. Compared with the traditional single plate and structure without tension detection, it realizes higher structural strength, optimized rope tension distribution and low-friction sliding, thus achieving the effects of improving the durability, stability and dynamic performance of the device.

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figures 1-6, a wave compensation fixed support device for ship transportation of offshore wind power components. The deck of the transport ship installed with this fixed support device is provided with a downward hollowed-out transport space, and this fixed support device is installed inside the transport space. This fixed support device includes a placement plate 1 and hydraulic struts 2. The upper surface of the placement plate 1 is used to place transported goods or instruments, and the lower surface is connected with hydraulic struts 2. The number of hydraulic struts 2 is not less than four. In this embodiment, the placement plate 1 is rectangular, and the number of hydraulic struts 2 is specifically four, which are respectively installed at the four corner positions around the placement plate 1. One end of the hydraulic strut 2 is connected to the bottom of the placement plate 1, and the other end is connected to the bottom of the transport space, supporting the placement plate 1 inside the installation space. The hydraulic strut 2 and the placement plate 1 are connected through a first hinge 3, and the hydraulic strut 2 and the bottom of the transport space are connected through a second hinge 4. The rotatable directions of the first hinge 3 and the second hinge 4 are perpendicular to each other, which are the rotational degrees of freedom in the front-back direction and the left-right direction respectively, so that the hydraulic strut 2 has rotational degrees of freedom in four directions at the same time.

[0039] The lower surface of the placement plate 1 is also connected with front-back hydraulic tie rods 5 and left-right hydraulic tie rods 8. One end of the front-back hydraulic tie rods 5 is connected to the placement plate 1, and the other end is connected to the front-back direction walls of the transport space; one end of the left-right hydraulic tie rods 8 is connected to the placement plate 1, and the other end is connected to the left-right direction walls of the transport space. In this embodiment, the number of front-back hydraulic tie rods 5 and left-right hydraulic tie rods 8 in both directions is two. Connecting to the walls and cooperating with the vertical hydraulic struts 2 keeps the placement plate 1 stable inside the installation space and can firmly support the transported items on the placement plate 1 when the ship is sailing smoothly.

[0040] The front-back hydraulic tie rods 5 and the placement plate 1 are connected through a third hinge 6, and the front-back hydraulic tie rods 5 and the wall are connected through a fourth hinge 7. The rotatable directions of the third hinge 6 and the fourth hinge 7 are perpendicular to each other. In this embodiment, the rotational direction of the third hinge 6 is the left-right direction, and the rotational direction of the fourth hinge 7 is the vertical direction; the left-right hydraulic tie rods 8 and the placement plate 1 are connected through a fifth hinge 9, and the left-right hydraulic tie rods 8 and the wall are connected through a sixth hinge 10. The rotatable directions of the fifth hinge 9 and the sixth hinge 10 are perpendicular to each other. In this embodiment, the rotational direction of the fifth hinge 9 is the front-back direction, and the rotational direction of the sixth hinge 10 is the vertical direction.

[0041] Please refer to Figure 8, hydraulic struts 2, front and rear hydraulic tie rods 5, and left and right hydraulic tie rods 8 are all provided with hydraulic cylinders 11 inside, and all have the freedom of expansion and contraction along their own axis directions; the second hinge 4, the fourth hinge 7, and the sixth hinge 10 are all fixedly connected to the ground and the wall; the hydraulic cylinders 11 are connected through a hydraulic control system, and the hydraulic control system controls the expansion and contraction amounts of the hydraulic struts 2, the front and rear hydraulic tie rods 5, and the left and right hydraulic tie rods 8 by controlling the hydraulic cylinders 11; the hydraulic control system includes sensors, a controller, and a hydraulic pump 12. Since the hydraulic control system is connected to the hydraulic rods (hydraulic struts, hydraulic tie rods) as an external system for controlling the expansion and contraction movement of the hydraulic rods, it is not shown in the figure. The hydraulic control system can adjust the position of the placement plate 1 in six degrees of freedom according to the state of the current transport ship affected by the waves, so that it always remains horizontal; because all three types of hydraulic rods have the freedom of expansion and contraction along their own axis directions, and together with the first hinge 3 and the second hinge 4, the third hinge 6 and the fourth hinge 7, and the fifth hinge 9 and the sixth hinge 10 with mutually perpendicular movement trajectories, the hydraulic struts 2, the front and rear hydraulic tie rods 5, and the left and right hydraulic tie rods 8 not only have their own expansion and contraction directions but also obtain an additional four degrees of freedom of movement in four directions. This design can easily achieve multi-dimensional coordinated movement without complicating the structure, greatly improving the flexibility and adaptability of the device, and the three types of hydraulic rods have only these six degrees of freedom, making the overall structure more stable.

[0042] In this embodiment, the sensors used include but are not limited to acceleration sensors, displacement sensors, gyroscopes, and tilt sensors. The sensors are signal-connected to the controller; the controller is signal-connected to the hydraulic pump 12. The specific structure is the same as that of the hydraulic lifting platform in the prior art and will not be elaborated in detail here.

[0043] Please refer to Figures 1-7, the placement plate 1 is rectangular, and a counterweight 13 is provided on the lower surface of the placement plate 1. In this embodiment, the number of counterweights 13 is specifically four, which are respectively distributed on the four sides of the lower surface of the placement plate 1. The counterweight 13 is slidably connected to the lower surface of the placement plate 1 through a slide rail 14. The upper surface of the slide rail 14 is fixedly connected to the lower surface of the placement plate 1; the counterweight 13 is connected with a pulling rope 15. One end of the pulling rope 15 is connected to the counterweight 13, and the other end is connected to the four corner endpoints of the placement plate 1. In specific implementation, the connection can be achieved through the cooperation of knotting and hooks. The pulling rope 15 passes through a pulley block 16. The number of pulley blocks 16 is not less than four. In this embodiment, it is specifically eight, which are respectively arranged at the four corners of the placement plate 1, with two at each corner; the counterweight 13 has a sliding degree of freedom along the direction of the slide rail 14. When the counterweight 13 generates a pulling force along the inclined direction of the placement plate 1 on the pulling rope 15, under the action of the fixed pulley 161, the inclined pulling force received by the pulling rope 15 is changed into a pulling force for pulling the placement plate 1 downward, and the pulling force position is at the four corner endpoints, close to the hydraulic support rod 2, so as to implement a downward passive compensation for the high hydraulic support rod 2.

[0044] Please refer to Figure 2 , in this drawing, only two counterweights 13 on the symmetry plane are marked. In actual use, the number of counterweights 13 is four, which are respectively arranged at the midpoints of the four sides of the lower surface of the placement plate 1. The pulling ropes 15 on the same side are respectively connected to both ends of the counterweight 13 on that side, and the connection points are symmetrically located. The angles formed between the pulling ropes 15 on the same side and the counterweight 13 on that side are of the same size, ensuring that the pulling forces on both ends of the pulling rope 15 are the same and making the structure more stable.

[0045] Please refer to Figure 3 , limiting devices 141 are provided at both ends of the slide rail 14. The limiting devices 141 include springs 1411 and baffles 1412. One side of the baffle 1412 faces the counterweight 13, and the other side is connected to the slide rail 14 through a spring 1411; a buffer pad 1413 is provided on the outer surface of the side of the baffle 1412 facing the counterweight 13, so that in special cases, when risks such as system failure exist, the counterweight 13 will not slip off both sides of the track, and the springs 1411 and the buffer pad 1413 can reduce the impact of the counterweight 13 on the baffle 1412 and avoid damage to the structure; the length of the slide rail 14 is not less than half of the side length of the placement plate 1 at its location. A rolling bearing 142 is provided between the counterweight 13 and the slide rail 14, which can reduce the friction between the counterweight 13 and the slide rail 14 and avoid more force being consumed.

[0046] Please refer to Figure 4 and Figure 7, the pulley block 16 includes a fixed pulley 161 and a movable pulley 162. The fixed pulley 161 is fixedly connected to the lower surface of the placement plate 1 and is used to change the direction of the force exerted on the pulling rope 15, converting the pulling force of the counterweight 13 into a pulling force capable of pulling the placement plate 1 downward. The movable pulley 162 is arranged at both ends of the counterweight 13. Hooks 131 are arranged at both ends of the counterweight 13 for connecting with the pulling rope 15. The pulling rope 15 passes through the hooks 131, and the movable pulley 162 is located inside the pulling rope 15 to reduce the friction between the pulling ropes 15. The two movable pulleys 162 located at both ends of the counterweight 13 are symmetrically positioned to ensure that the mechanisms on both sides of the counterweight 13 are exactly the same.

[0047] When the placement plate 1 tilts due to the influence of waves and the tilt amplitude is too large or the hydraulic system fails to adjust in time, the counterweight 13 slides along the slide rail 14 towards the lower side of the tilt under the action of gravity. As the counterweight 13 slides, the pulling rope 15 is subjected to a pulling force along the direction of the slide rail 14. Since the distance between the counterweight 13 and the high-end pulling rope 15 gradually increases, the angle between the pulling rope 15 and the counterweight 13 gradually decreases, and the pulling force gradually increases. The pulling rope 15 passes through the fixed pulley 161, converting the pulling force in the tilt direction into a vertically downward pulling force, which has a downward pulling effect on the high-end position of the placement plate 1, thereby passively adjusting the telescopic state of the hydraulic rod. Compared with the traditional pure hydraulic compensation structure, this device realizes the passive compensation function and the controllability of the sliding range, and can keep the platform stable when the active control system fails or responds insufficiently. At the same time, limit devices 141 are arranged at both ends of the slide rail 14 to prevent the counterweight 13 from sliding excessively, further enhancing the stability of the structure.

[0048] Please refer to Figure 7 , a tension sensor 151 is arranged on the pulling rope 15, and the tension sensor 151 is connected to the hydraulic control system by signal. A reinforcing rib structure 101 is arranged on the lower surface of the placement plate 1, and the reinforcing rib structure 101 is distributed crosswise along the length and width directions of the placement plate 1. The reinforcing rib structure 101 is fixedly connected to the placement plate 1 by welding or bolts. At the same time, to a certain extent, the slide rail 14 can also act as a reinforcing rib to reinforce the periphery of the placement plate 1. The design of the tension sensor 151 and the reinforcing rib structure 101 in the present invention enables the signal to be transmitted to the hydraulic control system through the tension sensor 151 when the pulling force of the pulling rope 15 is too large, thereby regulating the balance of the placement plate 1. Compared with the traditional single plate and the structure without tension detection, it realizes higher structural strength, optimized tension distribution of the pulling rope 15, and low-friction sliding, thus achieving the effects of improving the durability, stability, and dynamic performance of the device.

[0049] Working principle: This device is installed on a transport ship for maritime transportation. When the transport ship encounters wind and waves during navigation, causing the ship to heave, the hydraulic struts 2, front and rear hydraulic tie rods 5, and left and right hydraulic tie rods 8 will, under the coordination of the hydraulic control system, utilize the telescopic amount of the hydraulic cylinder 11 to adjust the lengths of the three types of hydraulic rods respectively, and cooperate with the hinges with mutually perpendicular rotation directions at both ends to achieve flexible coordination among six degrees of freedom; at the same time, the counterweight 13 arranged under the placement plate 1 plays a certain stabilizing role, and when the inclination amplitude of the placement plate 1 is too large, the counterweight 13 will slide along the slide rail 14 towards the lower end, tightening the pull rope 15 located at the high position. At this time, the fixed pulley 161 changes the direction of its pulling force into a pulling force along the hydraulic strut 2 downward, providing additional passive compensation for the hydraulic strut 2, and being able to maintain the stability of the platform when the active control system fails or has insufficient response.

[0050] In summary, for this marine wind power component ship transfer wave compensation fixed support device, through the collaborative work of the hydraulic struts 2 and hydraulic tie rods, precise compensation for the platform in three translational degrees of freedom of up and down, front and back, left and right and three rotational degrees of freedom of pitch, roll, and yaw is achieved, and it can effectively cope with wave motions under complex sea conditions, improving the stability and safety of the platform; on the basis of hydraulic active compensation, a passive compensation mechanism of the counterweight 13, slide rail 14, pull rope 15, and pulley block 16 is added. When the hydraulic system fails or has insufficient response, the passive compensation mechanism can still provide stable compensation ability, enhancing the reliability and adaptability of the device, and further enhancing the stability and anti-tilting ability of the platform; the device adopts a modular design, and components such as the hydraulic struts 2, hydraulic tie rods, and counterweight 13 are easy to install, disassemble, and maintain, improving the flexibility and scalability of the device and adapting to the transfer requirements of different specifications of marine wind power components.
