Description

Technical Field

[0001] This utility model relates to the field of jacket technology, specifically to a jacket for offshore wind turbines. Background Technology

[0002] Offshore wind turbine jackets generally consist of a superstructure, a substructure, and auxiliary structures. The superstructure is typically a flanged platform used to install the wind turbine equipment, including the tower, main unit, and blades. The substructure is a spatial frame structure composed of steel pipe piles. These piles are driven directly into the seabed, supporting the entire jacket and wind turbine, much like the legs of a stool resting on the seabed. As the foundation of the offshore wind turbine, the jacket's primary function is to provide a reliable support platform, ensuring the turbine can operate normally in complex marine environments. With its robust structure and reliable foundation, it withstands the enormous weight of the wind turbine, vibrations during operation, and the impact of strong winds and waves, ensuring the turbine's stability and safety. However, it lacks buffer protection for the lower part of the jacket. Due to the complex changes in water flow as waves propagate, these complex currents can impact the lower part of the jacket located in the seawater, or collisions between foreign objects in the sea and the frame can cause the jacket to sway, thus affecting the overall stability of the jacket and the wind turbine mounted on it. Utility Model Content

[0003] (1) Technical problems to be solved

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a wind turbine jacket for offshore wind turbines. This device aims to solve the problem that existing jackets lack buffer protection for the lower part of the jacket. Due to the complex changes in water flow during wave propagation, these complex water flows can impact the lower part of the jacket located in seawater, or collisions between foreign objects in the sea and the jacket structure can cause the jacket to sway, thus affecting the overall stability of the jacket and the wind turbine mounted on it.

[0005] (2) Technical solution

[0006] To solve the above-mentioned technical problems, this utility model provides a wind turbine jacket for offshore wind turbines, including a jacket body. Protective seats are installed on all four sides of the outer wall of the jacket body. Buffer grooves are opened at both ends inside the protective seats. A sliding groove is opened on one side of the outer wall of the protective seat located in the buffer groove. A sliding rod is slidably connected to the inner side of the sliding groove. A sealing gasket is embedded at one end of the inner wall of the sliding groove. The inner wall of the sealing gasket is in contact with the outer wall of the sliding rod. A flow-slowing protection mechanism is installed at the other end of the sliding rod. The flow-slowing protection mechanism includes a buffer component and a deflection component. The buffer component is used to reduce the impact force of the water flow, and the deflection component is used to deflect and unload drifting heavy objects.

[0007] When using one type of wind turbine jacket structure for offshore wind turbines according to this solution, the diverter seat installed in the center of the other side of the buffer seat first diverts the water flow, allowing the water flow to diffuse. Multiple sets of flow channels on both sides of the diverter seat on the outer wall of the buffer seat further disperse the water flow. The diverter components arranged in an alternating manner in the flow channels play a greater role. Multiple sets of first guide plates are installed on one side of the inner wall of the flow channel, and a second guide plate is installed between two adjacent sets of first guide plates. Together, they form a return cavity with a U-shaped side cross section. When the water flows through the flow channel, a local return flow is formed in the return cavity, allowing the water flow to collide with each other, further dispersing the water flow impact force and reducing the direct impact on the jacket structure. The structure is simple and easy to operate. It can buffer and protect the outer wall of the jacket structure located in seawater, reduce the sway amplitude of the jacket structure, and further improve the overall stability of the jacket structure.

[0008] Preferably, the buffer assembly includes an airbag installed on one side of the inner wall of the buffer groove, a pressure plate overlapping the other side of the airbag, and the other end of the pressure plate being fixedly connected to one end of the sliding rod.

[0009] Furthermore, side plates are installed at both ends of the inner wall of the buffer groove, and spring damping shock absorbers are installed on the other side of the side plates. A first linkage plate is installed at the other end of the spring damping shock absorber, and a second linkage plate is installed on one side of the outer wall of the first linkage plate.

[0010] Furthermore, the other end of the second linkage plate is rotatably connected to one side of the sliding rod, and a buffer seat is installed at the other end of the sliding rod. A flow divider is installed at the center of the other side of the buffer seat, and multiple sets of flow grooves are arranged on the outer wall of the buffer seat on both sides of the flow divider.

[0011] Furthermore, flow dividers are installed on both sides of the inner wall of the flow channel. The positions of the two flow dividers are staggered. Each flow divider includes multiple sets of first guide plates installed on one side of the inner wall of the flow channel. A second guide plate is installed between two adjacent sets of first guide plates on the inner wall of the flow channel.

[0012] Furthermore, a reflux cavity is formed between the two sets of first and second guide plates, and the side cross-section of the reflux cavity is U-shaped.

[0013] Furthermore, the deflection assembly includes a deflection roller rotatably connected to both ends inside the buffer seat, and multiple sets of buffer sleeves are fixedly sleeved on the outer wall of the deflection roller, the buffer sleeves being made of neoprene rubber.

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. In this utility model, the impact force of the water flow is reduced by the buffer component and the deflection component deflects and unloads the drifting heavy objects. The structure is simple and easy to operate. It can buffer and protect the outer wall of the main body of the jacket structure located in seawater, reduce the swaying amplitude of the main body of the jacket structure, and further improve the overall stability of the main body of the jacket structure.

[0017] 2. In this utility model, the diversion seat installed in the center of the other side of the buffer seat first plays a preliminary role in diverting the water flow, allowing the water flow to diffuse. Multiple sets of flow channels on both sides of the diversion seat on the outer wall of the buffer seat further disperse the water flow. The diversion components arranged in an alternating manner in the flow channels play a greater role. Multiple sets of first guide plates are installed on one side of the inner wall of the flow channel, and a second guide plate is installed between two adjacent sets of first guide plates. Together, they form a return cavity with a U-shaped side cross section. When the water flows through the flow channel, a local return flow is formed in the return cavity, allowing the water flow to collide with each other, further dispersing the water flow impact force and reducing the direct impact on the main body of the guide frame.

Detailed Implementation

[0025] This specific embodiment is a wind turbine jacket for offshore wind turbines, and its structural schematic diagram is shown below. Figure 1-6As shown, a wind turbine jacket for offshore wind turbines includes a jacket body 1. Protective seats 2 are installed on all four sides of the outer wall of the jacket body 1. Buffer grooves are formed at both ends of the inner side of each protective seat 2. A sliding groove is formed on one side of the outer wall of the protective seat 2 located within the buffer groove. A sliding rod 3 is slidably connected to the inner side of the sliding groove. A sealing gasket 4 is embedded at one end of the inner wall of the sliding groove, and the inner wall of the sealing gasket 4 is in contact with the outer wall of the sliding rod 3. A flow-damping protection mechanism is installed at the other end of the sliding rod 3. The flow-damping protection mechanism includes a buffer component and a deflection component. The buffer component reduces the impact force of the water flow, and the deflection component deflects and unloads drifting heavy objects. In use, this device reduces the impact force of the water flow through the buffer component and deflects and unloads drifting heavy objects through the deflection component. It has a simple structure and is easy to operate. It can buffer and protect the outer wall of the jacket body 1 located in seawater, reducing the swaying amplitude of the jacket body 1 and further improving the overall stability of the jacket body 1.

[0026] In this embodiment, the buffer assembly includes an airbag 5 installed on one side of the inner wall of the buffer tank, a pressure plate 6 attached to the other side of the airbag 5, and the other end of the pressure plate 6 fixedly connected to one end of the sliding rod 3. The protective seat 2 is installed on the four sides of the outer wall of the guide frame body 1, providing support and installation position for the entire protective structure. The buffer grooves at both ends inside the protective seat 2 are used to accommodate the buffer assembly and are the core space for playing the buffering role. The sliding groove on the outer wall provides a sliding track for the sliding rod 3. The sealing gasket 4 is tightly attached to the outer wall of the sliding rod 3 to prevent seawater and debris from entering the buffer tank and ensure the normal operation of the internal components.

[0027] Secondly, in this embodiment, side plates 7 are installed at both ends of the inner wall of the buffer tank, and spring damping shock absorbers 8 are installed on the other side of the side plates 7. A first linkage plate 9 is installed at the other end of the spring damping shock absorber 8, and a second linkage plate 10 is installed on one side of the outer wall of the first linkage plate 9. When the water flow impacts the fan duct frame, the force of the water flow pushes the sliding rod 3 to slide in the sliding groove. The sliding rod 3 is connected to the pressure plate 6. The pressure plate 6 compresses the air bladder 5 as the sliding rod 3 slides. The air bladder 5 is compressed and begins to deform, using its own elasticity to absorb part of the water flow. The impact force is initially buffered by the water flow. At the same time, the side plates 7 at both ends of the inner wall of the buffer tank are connected to the spring damping shock absorber 8. The other side of the spring damping shock absorber 8 is connected to the first linkage plate 9. The first linkage plate 9 is connected to the second linkage plate 10. The second linkage plate 10 is rotatably connected to the sliding rod 3. When the sliding rod 3 slides, it drives the second linkage plate 10 to move the first linkage plate 9. The spring damping shock absorber 8 absorbs and attenuates the vibration caused by the water flow impact, further reducing the impact of the water flow impact force on the main body 1 of the guide frame.

[0028] Furthermore, in this embodiment, the other end of the second linkage plate 10 is rotatably connected to one side of the sliding rod 3. A buffer seat 12 is installed on the other end of the sliding rod 3. A flow divider seat 13 is installed at the center of the other side of the buffer seat 12. Multiple sets of flow channels 11 are arranged on the outer wall of the buffer seat 12 on both sides of the flow divider seat 13. Flow divider components are installed on both sides of the inner wall of the flow channel 11. The positions of the two sets of flow divider components are staggered. The flow divider component includes multiple sets of first guide plates 14 installed on one side of the inner wall of the flow channel 11. A second guide plate 15 is installed between two adjacent sets of first guide plates 14 on the inner wall of the flow channel 11. A return cavity is formed between the two sets of first guide plates 14 and second guide plates 15. The side cross-section of the return cavity is U-shaped. The diverter seat 13 installed in the center of the other side of the buffer seat 12 first plays a preliminary role in diverting the water flow and spreading the water flow. Multiple sets of flow channels 11 on both sides of the diverter seat 13 on the outer wall of the buffer seat 12 further disperse the water flow. The diverter components arranged in a staggered manner in the flow channel 11 play a greater role. Multiple sets of first guide plates 14 are installed on one side of the inner wall of the flow channel 11. A second guide plate 15 is installed between two adjacent sets of first guide plates 14. Together they form a return cavity with a U-shaped side cross-section. When the water flows through the flow channel 11, a local backflow is formed in the return cavity, allowing the water flow to collide with each other and disperse the water flow impact force again, reducing the direct impact on the main body 1 of the guide frame.

[0029] Furthermore, in this embodiment, the deflection assembly includes a deflection roller 16 rotatably connected to both ends of the buffer seat 12. Multiple sets of buffer sleeves 17 are fixedly sleeved on the outer wall of the deflection roller 16. The buffer sleeves 17 are made of neoprene rubber. When a drifting heavy object approaches the wind turbine duct frame, the deflection roller 16 rotatably connected to both ends of the buffer seat 12 begins to function. When the heavy object contacts the deflection roller 16, since the deflection roller 16 can rotate, it can change the direction of movement of the heavy object, thereby deflecting the heavy object. The multiple sets of buffer sleeves 17 fixedly sleeved on the outer wall of the deflection roller 16 are made of neoprene rubber, which is resistant to seawater corrosion and has good elasticity. The buffer sleeves 17 further absorb the impact force when the heavy object hits, protecting the deflection roller 16 and reducing damage. At the same time, they reduce the impact force of the heavy object on the duct frame, thus completing the deflection and unloading of the drifting heavy object.

[0030] When using one type of wind turbine jacket frame for offshore wind turbines according to this scheme, the protective seat 2 is installed on the four sides of the outer wall of the jacket frame body 1, providing support and installation position for the entire protective structure. The buffer grooves at both ends of the protective seat 2 are used to accommodate the buffer components and are the core space for buffering. The sliding groove on the outer wall provides a sliding track for the sliding rod 3. The sealing gasket 4 is tightly attached to the outer wall of the sliding rod 3 to prevent seawater and debris from entering the buffer groove and ensure the normal operation of the internal components. When the water flow impacts the wind turbine jacket frame, the force of the water flow pushes the sliding rod 3 to slide in the sliding groove. The sliding rod 3 is connected to the pressure plate 6, and the pressure plate 6 moves with the sliding rod. The sliding compression airbag 5 of the 3rd layer deforms under compression, absorbing part of the impact force of the water flow using its own elasticity, thus initially buffering the impact force of the water flow. Simultaneously, the side plates 7 at both ends of the inner wall of the buffer tank are connected to the spring damping shock absorbers 8. The other side of the spring damping shock absorber 8 is connected to the first linkage plate 9, which is connected to the second linkage plate 10. The second linkage plate 10 is rotatably connected to the sliding rod 3. When the sliding rod 3 slides, it drives the second linkage plate 10, causing the first linkage plate 9 to move. The spring damping shock absorber 8 absorbs and attenuates the vibration caused by the water flow impact, further reducing the impact force of the water flow on the main jacket. Due to the influence of body 1, the diverter seat 13 installed in the center of the other side of the buffer seat 12 first diverts the water flow, causing it to diffuse. Multiple sets of flow channels 11 on both sides of the diverter seat 13 on the outer wall of the buffer seat 12 further disperse the water flow. The diverter components arranged in an alternating manner within the flow channels 11 play a greater role. Multiple sets of first guide plates 14 are installed on one side of the inner wall of the flow channels 11, and a second guide plate 15 is installed between two adjacent sets of first guide plates 14. Together, they form a return cavity with a U-shaped side cross-section. When the water flows through the flow channels 11, a local return flow is formed in the return cavity, allowing the water flows to collide with each other and further disperse the impact force of the water flow. To reduce the direct impact on the main body 1 of the jacket, when a drifting heavy object approaches the jacket, the deflection roller 16 connected to both ends of the buffer seat 12 begins to function. When the heavy object contacts the deflection roller 16, the direction of movement of the heavy object can be changed because the deflection roller 16 can rotate, thus deflecting the heavy object. Multiple sets of buffer sleeves 17 are fixedly sleeved on the outer wall of the deflection roller 16. They are made of neoprene rubber material that is resistant to seawater corrosion and has good elasticity. The buffer sleeves 17 further absorb the impact force when the heavy object hits, protect the deflection roller 16 and reduce damage, and at the same time reduce the impact force of the heavy object on the jacket, thus completing the deflection and unloading of the drifting heavy object.
