Description

Technical Field

[0001] The utility model relates to the technical field of offshore wind power generation, in particular to an anti-ice cone for offshore wind power generation. Background Art

[0002] In the construction of offshore wind farms, single pile foundations are used more and more widely. In order to extend the service life of offshore wind power generation equipment, anti-ice spikes are usually installed on the single pile foundation. The upper slope of the anti-ice spike is located above the sea surface, allowing ice blocks to collide with the upper slope to cause bending damage.

[0003] Deficiencies of existing technology:

[0004] Currently used anti-ice spikes are usually fixed structures to resist ice. However, due to the influence of ocean currents and sea breezes, some ice blocks will have an initial velocity when hitting the anti-ice spike. If there is no buffering, these ice blocks will easily hit the pile body quickly and cause displacement and damage to the single pile. In addition, some larger ice blocks will cause continuous damage to the anti-ice spike if they are not assisted in chiseling and breaking them up. Utility Model Content

[0005] The purpose of the present utility model is to provide an anti-ice cone for offshore wind power generation, so as to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: an anti-ice cone for offshore wind power generation, comprising a pile body, an anti-ice cone mechanism provided on the outer wall of the pile body, and the pile body and the anti-ice cone mechanism connected by a fixing assembly;

[0021] 1. The anti-ice cone for offshore wind power generation is provided with an anti-ice cone mechanism, which includes a base, a rotating rod and an ice hammer. Normally, the anti-ice cone shell plate on the outside of the pile body is used to resist and destroy ice blocks on the sea. Due to ocean currents or sea breezes, some ice blocks with faster speeds will first contact the anti-ice cone shell plate and squeeze the telescopic spring. At the same time, the anti-ice cone shell plate pushes the rotating rod to rotate, and the rotating rod drives the ice hammer to extend and chisel the ice blocks. The telescopic spring generates thrust to push the anti-ice cone shell plate to reset and push the ice blocks outward to change their movement direction. If the ice blocks continue to hit the pile body, the ice hammer will be driven to extend to chisel the ice blocks. The anti-ice cone mechanism uses the impact generated by the ice blocks to drive the ice hammer to chisel and decompose the ice blocks, thereby reducing the load of the anti-ice cone mechanism, and using the elastic force of the telescopic spring to push the ice blocks in the opposite direction, providing a buffer to the pile body and extending the service life.

[0022] 2. This anti-ice cone for offshore wind power generation is provided with a fixing assembly, which includes a screw, a mounting seat and a fixing collar.

Then the fixing collar is put on the outside of the screw, and the fixing nut is screwed on to complete the fixation of the mounting seat. The fixing assembly is used to initially fix the screw and the limit block, and then the fixing collar and the fixing nut are used to complete the fixed connection between the mounting seat and the pile body.

At the same time, the anti-ice cone shell plate 212 pushes the rotating rod 22 to rotate, and the rotating rod 22 drives the ice hammer 23 to extend and chisel the ice cubes. The telescopic spring 211 generates a thrust to push the anti-ice cone shell plate 212 to reset and push the ice cubes outward to change their direction of movement. If the ice cubes continue to hit the pile body 1, the ice hammer 23 will be driven to extend to chisel the ice cubes. The anti-ice cone mechanism 2 uses the impact generated by the ice cubes to drive the ice hammer 23 to chisel and decompose the ice cubes, thereby reducing the load of the anti-ice cone mechanism 2, and using the elastic force of the telescopic spring 211 to push the ice cubes in the opposite direction, and provide the pile body 1 with a buffer, thereby extending its service life.

The adjacent surfaces of the limit block 321 and the screw 31 are mutually matched inclined surfaces. A compression spring 322 is sleeved on the outer side of the limit block 321. The fixing collar 33 is sleeved on the outer side of the screw 31. A fixing nut 311 is provided on the outer side of the screw 31 and is located on one side of the fixing collar 33.

[0039] The working principle of this utility model is as follows:

[0040] When using an anti-ice spike for offshore wind power generation in this embodiment, the base 21 and the screw rod 31 are first aligned and then assembled. The limit block 321 first contacts the inclined surface on the outside of the screw rod 31 and squeezes the compression spring 322 until the limit block 321 moves to the other side of the inclined surface of the screw rod 31. The compression spring 322 pushes the limit block 321 to reset, and the limit block 321 and the screw rod 31 are initially fixed to each other. Then, the fixing collar 33 is put on the outside of the screw rod 31, and the fixing nut 311 is screwed on to complete the fixation of the mounting seat 32. The screw rod 31 and the limit block 321 are initially fixed by the fixing assembly 3. Then, the fixing collar 33 and the fixing nut 311 are used to complete the fixed connection between the mounting seat 32 and the pile body 1. Normally, the anti-ice spike on the outside of the pile body 1 is used. The shell plate 212 is used to resist and destroy ice cubes on the sea. Due to ocean currents or sea breezes, some faster ice cubes will be blown over. These ice cubes will first contact the anti-ice cone shell plate 212 and squeeze the telescopic spring 211. At the same time, the anti-ice cone shell plate 212 pushes the rotating rod 22 to rotate, and the rotating rod 22 drives the ice hammer 23 to extend and chisel the ice cubes. The telescopic spring 211 generates a thrust to push the anti-ice cone shell plate 212 to reset and push the ice cubes outward to change their direction of movement. If the ice cubes continue to hit the pile body 1, the ice hammer 23 will be driven to extend to chisel the ice cubes. The anti-ice cone mechanism 2 uses the impact generated by the ice cubes to drive the ice hammer 23 to chisel and decompose the ice cubes, thereby reducing the load of the anti-ice cone mechanism 2. The elastic force of the telescopic spring 211 is used to push the ice cubes in the opposite direction, and provide a buffer to the pile body 1 to extend its service life.
