[0028] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0029] Reference Figure 1-7 A detachable offshore wind turbine anti-collision device includes a tower, multiple snap-fit ​​seats 2 and multiple anti-collision posts 4;

[0030] Multiple snap-fit ​​seats 2 are movably abutted against the outside of the tower. Four snap-fit ​​half-rings 1 are movably snap-fitted on the outer periphery of the tower. The four snap-fit ​​half-rings 1 are located on two horizontal planes. Two snap-fit ​​half-rings 1 located on the same horizontal plane are spliced ​​into a circle and fixed by bolts. Multiple snap-fit ​​seats 2 are located on the side of two corresponding snap-fit ​​half-rings 1 that are close to each other. Multiple limiting screws 11 are fixedly installed on the top side of the two lower snap-fit ​​half-rings 1. Mounting holes are opened on the two upper snap-fit ​​half-rings 1. Limiting holes 21 are opened on the multiple snap-fit ​​seats 2. The multiple limiting screws 11 pass through the corresponding limiting holes 21 and mounting holes and are threaded with two nuts, which can stably limit the multiple snap-fit ​​seats 2. In order to effectively resist the corrosion of seawater and ensure that it can maintain good structural stability and connection strength when used in a marine environment for a long time, and extend the overall service life of the device, the limiting screws 11 and nuts are made of 316 stainless steel.

[0031] Furthermore, multiple snap-fit ​​seats 2 are all arc-shaped and detachably installed on the side where two snap-fit ​​limiting components are close to each other. Multiple anti-collision posts 4 are distributed in a circular array centered on the tower, and all of the anti-collision posts 4 are arranged parallel to each other with the tower. A hollow plate 31 is hinged to the side of the snap-fit ​​seat 2 away from the tower. A strip plate 32 is slidably installed inside the hollow plate 31. The end of the strip plate 32 away from the hollow plate 31 is hinged to the corresponding anti-collision post 4. A damping spring 33 is fixedly installed on the inner wall of the hollow plate 31, and the damping spring 33 is fixedly connected to the end of the strip plate 32 away from the anti-collision post 4, which can... The device provides a cushioning effect when impacted and also provides effective support for the anti-collision post 4. In order to guide and cushion the strip plate 32 as it slides along the hollow plate 31, reduce frictional loss between the strip plate 32 and the hollow plate 31, and reduce the vibration phenomenon that may occur due to the reaction force of the damping spring 33, thereby improving overall stability and service life, two guide grooves 35 are opened on the inner side wall of the hollow plate 31, and two damping sliders 34 are fixedly installed on the strip plate 32. The two damping sliders 34 are slidably installed in the corresponding guide grooves 35 respectively.

[0032] Two anti-collision posts 4 located on the same side of the vertical plane containing the tower axis and not adjacent to each other are hinged with the same connecting rod 5. Multiple connecting rods 5 are located in two mutually parallel planes. Two positioning pins 51 are fixedly installed on the top side of the multiple lower connecting rods 5. Positioning holes are opened on the multiple upper connecting rods 5. Multiple positioning pins 51 are inserted into the corresponding positioning holes respectively, which can connect and position the multiple connecting rods 5, so that they form an integral frame after assembly. This can further improve the overall stability and impact resistance of the structure, and ensure that all anti-collision posts 4 can work together to disperse the impact force.

[0033] Two anti-collision cylinders 41 are rotatably installed on the anti-collision post 4. The anti-collision cylinders 41 are rotatably connected to the anti-collision post 4 through bearings, so that the anti-collision cylinders 41 can rotate when subjected to lateral impact, converting part of the impact force into rotational kinetic energy, further improving the buffering effect, and avoiding damage to the anti-collision post 4 or the tower due to rigid collision.

[0034] In this embodiment, in order to absorb some of the impact energy through its own deformation when in contact with a ship or other impacting object, and at the same time reduce the reaction force on the impacting object and reduce the degree of damage to both parties, the anti-collision cylinder 41 is made of high-density polyethylene material, which has a smooth surface and a certain degree of elasticity.

[0035] In this embodiment, in order to ensure that the device always floats on the seawater and avoids losing its function when the tide rises or falls, the anti-collision cylinder 41 is hollow.

[0036] Working principle: In use, firstly, four snap-fit ​​semi-rings 1 are snapped into the tower from both sides. Two snap-fit ​​semi-rings 1 located on the same horizontal plane are fixed together with bolts to form two sets of ring structures, one above the other. This circular structure is not fixed to the outer wall of the tower. Next, multiple arc-shaped snap-fit ​​seats 2 are attached to the outer side of the tower, so that the limiting screw 11 passes through the limiting hole 21 on the snap-fit ​​seat 2 and the mounting hole of the upper snap-fit ​​semi-ring 1. The nut is tightened for temporary limiting. Then, a hollow plate 31 is hinged to the outer side of each snap-fit ​​seat 2. A strip plate 32 is slid into the hollow plate 31 and connected with a damping spring 33. Finally, the end of the strip plate 32 away from the hollow plate 31 is hinged to the anti-collision post 4 to ensure multiple The anti-collision posts 4 are arranged in a circular array around the tower. Then, connecting rods 5 are hinged between the anti-collision posts 4 located on the same side of the tower but not adjacent. The positioning pins 51 on the lower connecting rods 5 are inserted into the positioning holes of the upper connecting rods 5 to form a stable double-layer frame structure. Then, the nuts on the limiting screws 11 are tightened, and the number of nuts on each limiting screw 11 is not less than two. Finally, two hollow high-density polyethylene anti-collision cylinders 41 are installed on each anti-collision post 4 through bearings to complete the assembly of the entire device. The bearings are selected according to the actual use environment, such as stainless steel sealed bearings that can resist seawater.

[0037] When a ship or other object collides with the anti-collision cylinder 41, the anti-collision cylinder 41 converts part of the impact force into kinetic energy by rotating, and at the same time pushes the anti-collision column 4 to move. Since all the connecting rods 5 form a stable double-layer frame structure, multiple strip plates 32 can compress or stretch the corresponding damping springs 33 respectively, and the damping slider 34 slides in the guide groove 35 to further buffer the impact force, thereby dispersing and dissolving the impact force and effectively protecting the safety of the tower. Since the anti-collision cylinder 41 is hollow, the device can always remain floating on the sea surface and move along the axis of the tower, avoiding the influence of tides and waves.

[0038] When disassembly is required, first remove the nut on the limiting screw 11, then remove the bolt used to fix the upper snap-fit ​​half ring 1, then disconnect any of the upper connecting rods 5 from the corresponding anti-collision post 4, and then pull the upper connecting rods 5 together with the corresponding anti-collision posts 4 upwards until they are no longer in contact with the positioning pin 51 and the limiting screw 11. Then you can remove the upper connecting rods 5, snap-fit ​​seat 2 and the corresponding anti-collision posts 4 together. Then disassemble the lower part in the same way. After all these are removed, release the bolt on the lower snap-fit ​​half ring 1 to complete the disassembly operation.

[0039] The above provides a detailed description of a detachable offshore wind turbine anti-collision device provided by this utility model. Specific embodiments have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
