Description

Technical Field

[0001] This utility model relates to the technical field of offshore wind power transportation devices, specifically an offshore wind power monopile foundation ship transportation support device. Background Technology

[0002] With the increasing global demand for renewable energy, offshore wind power, as a clean and renewable energy source, has received widespread attention. Offshore wind power projects are typically located in waters some distance offshore, utilizing abundant offshore wind resources to generate electricity. With technological advancements and cost reductions, offshore wind power is gradually expanding into deeper waters to access more stable and abundant wind resources. Monopile foundations are one of the most widely used foundation types in offshore wind power projects. They primarily consist of a single, large-diameter steel pipe pile, driven to a certain depth below the seabed to provide stable support. Monopile foundations offer advantages such as simple structure, quick construction, and relatively low cost, thus finding widespread application in offshore wind power projects.

[0003] In the existing transportation process, the use of cranes for transporting monopiles may subject them to external forces such as vibration and impact, resulting in surface damage or structural deformation. This damage may affect the installation and use of the monopile foundation, and may even lead to the failure of the entire project. Furthermore, during transportation, since monopiles are cylindrical, they are easily displaced by the impact of waves on the transport ship, causing safety hazards. Therefore, a support device is needed that can separate individual monopiles and stabilize and keep them level. Summary of the Invention

[0004] (I) Technical problem to be solved: In view of the shortcomings of the existing technology, this utility model provides a ship transport support device for offshore wind power monopile foundations, which has the advantages of placing each monopile stably and separately, ensuring that the monopile will not collide with each other and maintaining a horizontal position. It solves the problems of the existing technology, which uses a crane to place monopile, which is prone to collision between the monopile and the ground, causing damage, and the monopile will be displaced when encountering waves during transportation.

[0005] (II) Technical Solution: To achieve the above-mentioned goal of placing each monopile stably and separately, ensuring that the monopiles do not collide with each other and remain horizontal, this utility model provides the following technical solution: A marine transport support device for offshore wind power monopile foundations, including fixed supports, the number of which is not less than two, evenly distributed along a straight line, the upper end of the fixed supports is provided with a slot, the slot is arc-shaped; a support pad is provided inside the slot, the support pad is arrayed along the arc-shaped surface of the slot; a wave compensation mechanism is provided at the lower end of the fixed supports, the lower end of the wave compensation mechanism is fixedly connected to the surface on which the device is placed; a support rod is provided between the lower end of the fixed supports and the wave compensation mechanism, the number of which is not less than four, the support rod is evenly distributed around the fixed supports.

[0006] Preferably, the fixed supports are symmetrically distributed on both sides of the single pile, that is, the fixed supports are provided at both ends of the single pile.

[0007] Preferably, the upper surface of the support pad is provided with an anti-slip pad made of elastic material.

[0008] Preferably, the support rods are symmetrically distributed along the centerline of the fixed bracket.

[0009] Preferably, a spring structure is provided between the support pad and the slot.

[0010] Preferably, the connection between the fixed bracket and the support rod is provided with a connection structure made of elastic material.

[0011] Preferably, a pin is provided at the middle position inside the upper end of the fixed bracket, and a matching pin hole is opened on the outer surface of the single pile transported by the support device.

[0012] Preferably, a groove is provided in the middle of the upper end of the fixed bracket, and the pin rod is connected to the fixed bracket through the groove. Springs of the same specification are fixedly connected to both ends of the groove, and the other end of the spring is fixedly connected to the outer surface of the pin rod.

[0013] Preferably, the wave compensation mechanism includes a double-acting hydraulic cylinder and a piston rod. The upper end of the piston rod is fixedly connected to the support rod. The piston rod is located inside the double-acting hydraulic cylinder and is movable inside the double-acting hydraulic cylinder. The number of double-acting hydraulic cylinders is the same as the number of support rods. All the double-acting hydraulic cylinders are connected by oil pipes to achieve a closed loop.

[0014] Preferably, a sealing ring is provided at the connection between the oil pipe and the double-acting hydraulic cylinder.

[0015] (III) Beneficial Effects: Compared with the prior art, this utility model provides a ship transportation support device for offshore wind power monopile foundations, which has the following beneficial effects:

[0016] 1. This type of offshore wind power monopile foundation ship transport support device ensures the stability of the monopile during transportation by connecting a wave compensation mechanism to the lower end of the fixed support. Even in the face of surging waves, it can maintain a horizontal state, effectively preventing slippage and greatly reducing safety hazards. In actual use, the slot of the fixed support is used to place the monopile. When the transport ship encounters waves, the waves will lift the fixed support in a certain direction. At this time, the fixed support in that direction will be subjected to an upward impact force. This impact force will temporarily increase the contact pressure between the support pad and the monopile foundation, and cause the support rod in that direction to apply a greater thrust to the piston rod below, causing the piston rod to move downward. The piston rods of the hydraulic cylinders in other directions will adjust accordingly, either extending outward to maintain system balance or remaining in place to maintain the current state. This intelligent adjustment mechanism ensures that the fixed support can respond quickly and maintain overall balance regardless of the direction of the waves, thereby ensuring the stability of the monopile during transportation.

[0017] 2. This type of marine transport support device for offshore wind power monopile foundations features slots on the fixed brackets specifically designed for fixing monopiles. The arc-shaped design not only conforms to the shape of the monopile but also enhances the stability of the fixation. Furthermore, the internal design incorporates support pads distributed along an arc array, with anti-slip pads on the upper surface. This reduces the contact area while maintaining the same weight of the monopile, thereby increasing friction and effectively preventing the monopile from swaying and sliding during transport. It also avoids collisions between the monopile and the slots during transport, protecting the outer surface of the monopile and improving stability during transport. A spring mechanism is also designed between the support pads and the slots, which can quickly and effectively absorb and buffer the impact force when encountering wave impacts, preventing damage caused by direct collisions and ensuring the integrity of the monopile and its support structure.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 A vessel transport support device for offshore wind turbine monopile foundations includes at least two fixed supports 1, evenly distributed along a straight line. Each fixed support 1 has a slot 10 at its upper end, the slot 10 being arc-shaped. This arc-shaped design not only conforms to the shape of the monopile but also enhances the stability of the fixation. Support pads 11 are arranged inside the slot 10, arrayed along the arc-shaped surface of the slot 10. The upper surface of each support pad 11 is covered with an anti-slip pad made of an elastic material, specifically rubber in this example. The design of the support pads 11 is based on the monopile weight... While keeping the quantity constant, the contact area is reduced, thereby increasing the friction force, effectively preventing the monopile from shaking and sliding during transportation, avoiding collisions between the monopile and the slot 10 during transportation, protecting the outer surface of the monopile, and improving the stability during transportation; a wave compensation mechanism 2 is provided at the lower end of the fixed support 1, and the lower end of the wave compensation mechanism 2 is fixedly connected to the surface on which the device is placed; a support rod 3 is provided between the lower end of the fixed support 1 and the wave compensation mechanism 2, and the number of support rods 3 is not less than four, and the support rods 3 are evenly and symmetrically distributed around the fixed support 1.

[0026] Please see Figure 1 Fixed supports 1 are symmetrically distributed on both sides of the single pile, that is, fixed supports 1 are set at both ends of the single pile to ensure the stability of the single pile during transportation.

[0027] Please see Figure 3 A spring structure 12 is provided between the support pad 11 and the groove 10, which can quickly and effectively absorb and buffer the impact force when encountering wave impact, avoid damage caused by direct collision, and ensure the integrity of the monopile and its support structure.

[0028] Please see Figure 4A connecting structure 4 made of elastic material is provided at the connection between the fixed bracket 1 and the support rod 3. In this embodiment, the material of the connecting structure 4 is rubber. The elastic connecting structure 4 can increase the tolerance of deformation between the support rod 3 and the fixed bracket 1, neutralize the rigidity between the fixed bracket 1 and the support rod 3, and prevent the structure from deforming at the connection due to excessive rigidity under the dual action of wave impact and wave compensation mechanism 2.

[0029] Please see Figures 3-5 A pin rod 5 is installed at the middle of the upper end of the fixed bracket 1. The outer surface of the monopile transported by the support device has a matching pin hole 50. During transportation, the pin hole 50 is aligned with the pin rod 5 to limit the monopile in the horizontal direction. In actual use, the pin hole 51 can be flexibly deformed into a pin groove, pin ring, or any other shape that matches the pin rod 51 and achieves the limiting function. The pin hole 50 can also be installed on the outer surface of the monopile using external equipment, such as by making a pin hole 50 in a rubber ring and then fitting the rubber ring onto the monopile. The upper end of the fixed bracket 1 has a groove 51 in the middle. The pin 5 is connected to the fixed bracket 1 through the groove 51. The pin 5 can slide inside the groove 51. Therefore, when the single pile moves along the axis due to the action of the waves, the pin 5 slides synchronously inside the groove 51 to ensure the limit of the single pile and prevent the single pile from tilting. The two ends of the groove 51 are fixedly connected with springs of the same specification. The other end of the spring is fixedly connected to the outer surface of the pin 5. This spring design can prevent the pin 5 from colliding with the inner side of the groove 51 under large-amplitude movement.

[0030] Please see Figures 3-4 The wave compensation mechanism 2 includes a double-acting hydraulic cylinder 20 and a piston rod 21. The upper end of the piston rod 21 is fixedly connected to the support rod 3. The piston rod 21 is vertically upward and located inside the double-acting hydraulic cylinder 20. The piston rod 21 is movable inside the double-acting hydraulic cylinder 20. The number of double-acting hydraulic cylinders 20 is the same as that of the support rod 3. All double-acting hydraulic cylinders 20 are connected by oil pipes 22 to achieve a closed loop. When one piston rod 21 moves in the vertical direction, the other piston rods 21 perform compensating movements. A sealing ring is provided at the connection between the oil pipe 22 and the double-acting hydraulic cylinder 20 to ensure sealing and prevent oil leakage.

[0031] Working Principle: In actual use, the slot 10 of the fixed support 1 is used to place the monopile. When the transport ship encounters waves, the waves will raise the fixed support 1 in a certain direction. At this time, the fixed support 1 in that direction will be subjected to an upward impact force. This impact force will temporarily increase the contact pressure between the support pad 11 and the monopile foundation, and cause the support rod 3 in that direction to apply a greater thrust to the piston rod 21 below, causing the piston rod 21 to move downward. The piston rods 21 of the hydraulic cylinders in other directions will adjust accordingly, either extending outward to maintain system balance or remaining in place to maintain the current state. This intelligent adjustment mechanism ensures that no matter which direction the waves come from, the fixed support 1 can respond quickly and maintain overall balance through the sliding of the pin rod 5 on the slide groove 51 and the compensation of the double-acting hydraulic cylinder 20. The connection structure 4 increases the flexibility between the equipment structures, preventing excessive deformation, thereby ensuring the stability of the monopile during transportation.
