[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1-Figure 3 The utility model provides an embodiment: an offshore wind power platform pile-sinking anti-collision device, comprising a base 1, a supporting column 4 is fixedly connected to the middle part of the base 1, a connecting block 11 is fixedly connected to the supporting column 4, a connecting column 12 is fixedly connected to the bottom of the connecting block 11, a spring 13 is sleeved on the outside of the connecting column 12, a hollow column 6 is slidably connected to the connecting column 12, a threaded rod 14 is fixedly connected to the top surface of the connecting column 12, a limiting plate 7 is fixedly connected to the top surface of the hollow column 6, an opening 8 is provided in the limiting plate 7, the opening 8 is slidably connected to the threaded rod 14, a limiting plate 2 16 is slidably connected to the threaded rod 14, a bolt 15 is fixedly connected to the top surface of the limiting plate 2 16, the bolt 15 is threadedly connected to the threaded rod 14, two groups of limiting plates 7 are arranged in parallel, a groove 17 is provided on the connecting block 11, a connecting shaft 2 10 is rotatably connected to the groove 17, a clamping block 9 is fixedly connected to the connecting shaft 2 10, and one end of the clamping block 9 is abutted between the two groups of limiting plates 7.

[0024] A connecting shaft 2 is rotatably connected to the outer side of the top surface of the base 1, an anti-collision column 3 is fixedly connected to the connecting shaft 2, and a top plate 5 is rotatably connected to the top of the connecting shaft 2, which effectively buffers the external impact force. The bottom of the hollow column 6 abuts against the top of the spring 13, effectively supports the limit plate 7, and enhances the stability of the limit plate 7. The clamping block 9 is L-shaped, which effectively fixes the anti-sinking pile fixing seat. There are multiple groups of connecting shafts 2 and anti-collision columns 3, which are distributed circumferentially on the outer side of the base 1, which further weakens the impact force. Three groups of clamping blocks 9 are provided, which are distributed circumferentially on the connecting block 11, and enhance the stability of the anti-sinking pile when fixed.

[0025] Working principle: when fixing the anti-sinking pile, put the hollow fixing seat of the anti-sinking pile into the connecting block 11, rotate the bolt 15, the bolt 15 is threadedly connected to the threaded rod 14, and the bolt 15 moves downward through the thread, driving the limit plate 2 16 on the bolt 15 to squeeze the top surface of the limit plate 1 7. When the limit plate 1 7 moves downward, it drives the hollow column 6 to slide on the connecting column 12 and squeeze the clamping block 9. The clamping block 9 rotates in the groove 17 on the connecting block 11. The three groups of clamping blocks 9 clamp the hollow fixing seat of the anti-sinking pile at the same time, and the anti-sinking pile is quickly fixed. At the same time, the squeezed spring 13 exerts a reverse force on the hollow column 6, which enhances the stability of the limit plate 1 7 and ensures the fixation of the anti-sinking pile by the clamping block 9. When impacted, the external impact force collides with the anti-collision column 3, and the anti-collision column 3 rotates to disperse and dilute the vertical impact force, effectively ensuring the safety of the anti-sinking pile structure.

[0026] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
