Offshore wind turbine foundation ice towing device

Abstract

This utility model provides a floating ice towing device for offshore wind turbine foundations, belonging to the field of offshore wind turbine technology. It includes: a towing structure body, with two sets of first electric cylinders installed on the upper surface of the towing structure body. One set of first electric cylinder piston rods has an ice-clearing mechanism installed on its surface, and an inclined guide plate is installed on the surface of the towing structure body. The other set of first electric cylinder piston rods has a cutting mechanism and a rolling mechanism installed on both sides of their respective surfaces. This solution uses the first electric cylinders to drive the cutting mechanism, rolling mechanism, and ice-clearing mechanism for height adjustment. Subsequently, the cutting mechanism and ice-clearing mechanism can crush the floating ice in front, forming a continuous ice-breaking channel and reducing towing resistance. Simultaneously, the first electric cylinders allow for dynamic cutting to adapt to different ice thicknesses, ensuring the straightness and stability of the towing path. Furthermore, the cutting mechanism, rolling mechanism, and ice-clearing mechanism preferentially contact the floating ice, replacing the main body of the equipment in bearing the impact and reducing the probability of structural damage.

[0002] With the development of the global economy and the increasing depletion of chemical energy resources, the demand for clean energy is growing daily. Offshore wind power, as a brand-new clean energy source, has good economic and environmental benefits, does not occupy land resources, has a short infrastructure construction time, large installed capacity, and minimal interference with human activities. It has become a research hotspot in global wind power development and an important direction for the development of global renewable energy.

[0003] Floating ice poses a significant threat to the towing path, dynamic response, and safety of offshore structures. However, most existing towing equipment is designed for ice-free waters and lacks ice-cutting structures to address the dynamic loads of floating ice. Floating ice accumulates at the front of the equipment, forming an ice barrier that significantly increases towing resistance, leading to a decrease in towing speed and an increase in energy consumption.

[0027] Please see Figure 1-5 The technical solution provided in this embodiment is as follows:

[0028] A floating ice towing device for offshore wind turbine foundations includes: a towing structure body 1, two sets of first electric cylinders 2 are installed on the upper surface of the towing structure body 1, an ice-clearing mechanism 3 is installed on the surface of the piston rod of one set of first electric cylinders 2, an inclined guide plate 4 is installed on the surface of the towing structure body 1, and a cutting mechanism 5 and a rolling mechanism 6 are respectively installed on both sides of the piston rod surface of the other set of first electric cylinders 2. The ice-clearing mechanism 3 includes an ice-clearing frame 301 fixedly connected to the surface of the piston rod of one set of first electric cylinders 2, an ice-clearing seat 302 is installed at the bottom of the ice-clearing frame 301, a plurality of rotating rods 303 are rotatably connected to the surface of the ice-clearing seat 302, and an ice-clearing blade 304 is fixedly connected to the bottom of the rotating rods 303.

[0029] The cutting mechanism 5 includes a movable seat 501 fixedly connected to the piston rod surface of another set of first electric cylinders 2. Multiple cutting frames 502 are slidably connected to the surface of the movable seat 501. A cutting blade 503 is rotatably connected to the bottom of the cutting frame 502. The first electric cylinder 2 drives the cutting mechanism 5, the roller pressing mechanism 6 and the ice clearing mechanism 3 to adjust their height. Then, the cutting mechanism 5 and the ice clearing mechanism 3 can crush the floating ice in front to form a continuous ice-breaking channel, reducing towing resistance. At the same time, the setting of the first electric cylinder 2 can dynamically cut and adapt to different ice thicknesses, ensuring the straightness and stability of the towing path. Furthermore, the cutting mechanism 5, the roller pressing mechanism 6 and the ice clearing mechanism 3 prioritize contact with the floating ice, replacing the main body of the equipment to bear the impact, reducing the probability of structural damage.

[0030] Specifically, a transmission gear 305 is fixedly connected to the surface of multiple rotating rods 303, and adjacent transmission gears 305 mesh with each other. A first servo motor 306 is mounted on the surface of the ice clearing seat 302, and the output shaft of the first servo motor 306 is fixedly connected to a rotating rod 303.

[0031] In a specific embodiment of this utility model, the first servo motor 306 starts its output shaft to drive a rotating rod 303 to rotate. At the same time, under the action of multiple transmission gears 305, multiple rotating rods 303 are rotated, and multiple ice-clearing blades 304 are driven to rotate alternately.

[0032] Specifically, the surface of the towing structure body 1 is provided with two guide rods 8, and sliding plates 7 are fixedly connected to both sides of the ice clearing seat 302, and the sliding plates 7 are slidably connected to the surface of the guide rods 8.

[0033] In a specific embodiment of this utility model, the movement of the ice clearing seat 302 causes the sliding plate 7 to move on the surface of the guide rod 8, thereby increasing the stability of the ice clearing seat 302 during movement.

[0034] Specifically, a second electric cylinder 504 is mounted on the surface of the cutting frame 502, and the piston rod of the second electric cylinder 504 is rotatably connected to the cutting blade 503.

[0035] In a specific embodiment of this utility model, by setting up a second electric cylinder 504, when the second electric cylinder 504 is started, its piston rod extends to drive the cutting blade 503 to adjust its angle, thereby realizing the adjustment of the cutting angle of the cutting blade 503.

[0036] Specifically, the surface of the cutting frame 502 is provided with a mounting frame 505, and the surface of the cutting frame 502 is provided with fixing bolts 506 that are adapted to the mounting frame 505.

[0037] In a specific embodiment of this utility model, the moving cutting frame 502 can be limited and fixed by the cooperation of the mounting frame 505 and the fixing bolt 506, thereby increasing the stability of the cutting blade 503 during the cutting process.

[0038] Specifically, the roller pressing mechanism 6 includes a mounting bracket 601 mounted on the piston rod surface of another set of first electric cylinders 2. A mounting plate 602 is rotatably connected to the surface of the mounting bracket 601. A roller pressing plate 603 is rotatably connected to the surface of the mounting plate 602. Multiple roller pressing shafts 604 are fixedly connected to the inner side of the roller pressing plate 603. A reinforcing ring 605 is provided on the surface of the roller pressing shaft 604.

[0039] In a specific embodiment of this utility model, the roller pressing shaft 604 will contact the ice surface. While the towing structure body 1 moves, it drives the roller pressing shaft 604 to move. At this time, the mounting plate 602 rotates on the surface of the mounting frame 601, and the roller pressing plate 603 rotates on the surface of the mounting plate 602, thereby improving the roller pressing effect of the roller pressing shaft 604 on the ice surface.

[0040] Working principle: The first electric cylinder 2 drives the cutting mechanism 5, the rolling mechanism 6, and the ice-clearing mechanism 3 to adjust their height. When the second electric cylinder 504 is started, its piston rod extends and drives the cutting blade 503 to adjust its angle, thereby adjusting the cutting angle of the cutting blade 503. The first servo motor 306 starts and its output shaft drives a rotating rod 303 to rotate. At the same time, under the action of multiple transmission gears 305, multiple rotating rods 303 rotate and drive multiple ice-clearing blades 304 to rotate alternately. At the same time, the towing structure body 1 moves and drives the rolling shaft 604 to move. At this time, the mounting plate 602 rotates on the surface of the mounting frame 601, and the rolling plate 603 rotates on the surface of the mounting plate 602, thereby improving the rolling effect of the rolling shaft 604 on the ice surface.
