[0002] Wind energy, as a clean and renewable green energy source, boasts high development efficiency and economic viability, making it a promising candidate for large-scale development and commercialization. Currently, wind farm development is gradually expanding from land to sea. The construction of offshore wind turbines requires stable foundation support, highlighting the crucial importance of offshore wind turbine foundation piles. However, most existing traditional offshore wind turbine foundation piles are monolithic structures that cannot be disassembled. This presents numerous difficulties for later maintenance and replacement. Once the support column is damaged, the inability to disassemble it makes targeted repair or replacement difficult, leading to high maintenance costs and potentially affecting the normal operation of the entire wind farm. Therefore, developing an easily disassembleable offshore wind turbine foundation pile is of significant practical importance. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an easily disassembled offshore wind power generation foundation pile. To achieve the above objectives, this utility model adopts the following technical solution:

[0004] A disassembleable offshore wind power foundation pile includes a support column and a foundation pile. The lower end of the support column is fixedly connected to a second plug, and the upper end of the foundation pile is fixedly connected to a first plug. Insertion holes are provided inside the lower end of the support column and the upper end of the foundation pile. The shape and depth of the insertion holes correspond to the shape and length of the first and second plugs, and they are movably inserted into each other. Pin holes are provided on the lower end of the support column and the first plug, and the two pin holes correspond to each other, with a first fixing pin movably inserted inside each pin hole. Pin holes are also provided on the upper end of the foundation pile and the second plug, and the two pin holes correspond to each other, with a second fixing pin movably inserted inside each pin hole.

[0005] Furthermore, a retaining ring is fitted at the connection between the support column and the foundation pile.

[0006] Furthermore, two sliding frames are fixedly connected to the outer side of the fixing ring at two locations, and the sliding frames allow the first fixing pin and the second fixing pin to pass through.

[0007] Furthermore, a limiting slider is slidably connected inside the sliding frame.

[0008] Furthermore, a threaded knob is movably connected to the limiting slider, and the threaded knob corresponds to the threaded hole opened on the slide frame and is threadedly engaged with it.

[0009] Furthermore, a sliding groove is provided on the inner side of the upper end of the fixing ring.

[0010] Furthermore, a positioning slide bar is slidably sleeved inside the slide bar groove.

[0011] Furthermore, a reinforcing plate is fixedly connected to the lower end of the foundation pile.

[0012] Furthermore, a foundation platform is fixedly connected to the lower end of the reinforcing plate and the foundation pile, and a spiral friction pile is fixedly connected to the lower end of the foundation platform.

[0013] Furthermore, the fixing ring has through holes corresponding to the positions of the first fixing pin and the second fixing pin, and the through holes are movably connected to the first fixing pin and the second fixing pin.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0025] like Figures 1 to 4 As shown, an easily disassembled offshore wind power foundation pile includes a support column 1 and a foundation pile 5. The lower end of the support column 1 is fixedly connected to a second plug 12, and the upper end of the foundation pile 5 is fixedly connected to a first plug. Both the lower end of the support column 1 and the upper end of the foundation pile 5 have insertion holes 14. The shape and depth of the insertion holes 14 correspond to the shape and length of the first plug 9 and the second plug 12, and they are movably inserted into each other. The lower end of the support column 1 and the first plug 9 both have pin holes 15, and the two pin holes 15 correspond to each other. A first fixing pin 13 is movably inserted into the pin hole 15. The upper end of the foundation pile 5 and the second plug 12 both have pin holes 15, and the two pin holes 15 correspond to each other. A second fixing pin 17 is movably inserted into the pin hole 15.

[0026] In this setup, the detachable design solves the problem of not being able to replace and maintain the damaged support column 1 later. At the same time, the simple quick-release design makes disassembly and installation faster and more efficient.

[0027] like Figures 1 to 4 As shown, in a specific embodiment, a fixing ring 4 is sleeved at the connection between the support column 1 and the foundation pile 5. A sliding frame 3 is fixedly connected to the lower left and upper right ends of the outer side of the fixing ring 4. A limiting slider 11 is slidably sleeved inside the sliding frame 3. A threaded knob 2 is movably connected to the limiting slider 11. The threaded knob 2 corresponds to the threaded hole opened on the sliding frame 3 and is threadedly sleeved with it.

[0028] In this setup, the first fixing pin 13 is inserted through the through hole at the upper right end of the fixing ring 4, the first plug 9, and the pin hole 15 on the support column 1. Then, the threaded knob 2 is rotated to lower the limiting slider 11, blocking the first fixing pin 13. Similarly, the installation method of the second fixing pin 17 is the same as the above steps.

[0029] like Figures 1 to 4As shown, in a specific embodiment, a slide groove 16 is provided on the inner side of the upper end of the fixing ring 4. A positioning slide 10 is slidably sleeved inside the slide groove 16. The inner side of the positioning slide 10 is fixedly connected to the outer surface of the lower end of the support column 1, and the length of the positioning slide 10 corresponds to the length of the slide groove 16.

[0030] In this setup, the positioning slide 10 fixed at the lower end of the support column 1 is aligned with the slide groove 16 and plugged into each other. The purpose of this design is to align the second plug 12 with the insertion hole 14 at the upper end of the foundation pile 5 to prevent rotational displacement when it is inserted downwards.

[0031] like Figures 1 to 4 As shown, in a specific embodiment, a reinforcing plate 6 is fixedly connected to the lower end of the foundation pile 5, a foundation platform 7 is fixedly connected to the reinforcing plate 6 and the lower end of the foundation pile 5, and a spiral friction pile 8 is fixedly connected to the lower end of the foundation platform 7.

[0032] In this setup, the foundation platform 7 and the spiral friction pile 8 are used to firmly fix the foundation pile 5 to the seabed.

[0033] like Figures 1 to 4 As shown, in a specific embodiment, the lower left end and the upper right end of the fixing ring 4 are provided with through holes, which correspond to the first fixing pin 13 and the second fixing pin 17 and are movably connected with them.

[0034] In this setup, when the support column 1 needs to be installed, first, the fixing sleeve 4 is fitted onto the foundation pile 5. Then, the second fixing pin 17 is inserted into the through hole at the lower left end of the fixing ring 4 and the pin hole 15 on the outer side of the upper end of the foundation pile 5, but not into the insertion hole 14. Then, the threaded knob 2 at the lower left end of the fixing ring 4 is rotated to fix the second fixing pin 17 through the limiting slider 11.

[0035] The implementation principle of this embodiment is as follows:

[0036] By adopting a detachable design, the problem of not being able to replace and maintain the damaged support column 1 in the later stage is solved. At the same time, the simple quick-release design makes disassembly and installation faster and more efficient.

[0037] When installing the support column 1, first, fit the fixing sleeve 4 onto the foundation pile 5. Then, insert the second fixing pin 17 into the through hole at the lower left end of the fixing ring 4 and the pin hole 15 on the outer side of the upper end of the foundation pile 5, but do not insert it into the insertion hole 14. Then, rotate the threaded knob 2 at the lower left end of the fixing ring 4 to fix the second fixing pin 17 through the limiting slider 11. Then, align the positioning slide 10 fixed at the lower end of the support column 1 with the slide groove 16 and insert them together. The purpose of this design is to connect the second plug 12 to the upper end of the foundation pile 5. Align the sockets 14 to prevent rotational displacement when they are inserted downwards. At the same time, the first plug 9 and the second plug 12 are respectively inserted into the sockets 14 at the lower end of the support column 1 and the sockets 14 at the upper end of the foundation pile 5. Then, the first fixing pin 13 passes through the through hole at the upper right end of the fixing ring 4 and the pin hole 15 opened on the first plug 9 and the support column 1, and is inserted into them. Then, rotate the threaded knob 2 to lower the limiting slider 11 and block the first fixing pin 13. Similarly, the installation method of the second fixing pin 17 can be repeated by repeating the above steps.

[0038] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
