[0018] The preferred embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings.

[0019] like Figure 1 , Figure 2As shown, an offshore wind power single pile fixing device includes a pile body 1, and a first fixing component is arranged on the pile body 1, the first fixing component includes a first fixing plate 2 and a second fixing plate 5 connected to the pile body 1, and the first fixing plate 2 and the second fixing plate 5 are linearly provided with a plurality of limit plates 8, and the longitudinal sections of the plurality of limit plates 8 are all in the shape of a right-angled trapezoid, and the longitudinal cross-sectional area of ​​the plurality of limit plates 8 gradually decreases from bottom to top, so that the surface of the device is more complex and the fixing effect is good, and a second fixing component is arranged on the inner wall of the pile body 1, and the second fixing component includes a baffle connected to the pile body 1 and a plug plate 3 located at the bottom end of the baffle, the cross section of the plug plate 3 is cross-shaped, and a fixing thorn 4 is arranged at the bottom end of the plug plate 3 for easy insertion into the soil, and a drainage groove and a groove matching the first fixing plate 2 and the second fixing plate 5 are arranged on the pile body 1, and the drainage groove is convenient for discharging excess seawater in the pile body 1 below the baffle.

[0020] like Figure 3 , Figure 4 As shown, the pile body 1 is provided with a driving assembly connected to the first fixed plate 2 and the second fixed plate 5, and the first fixed plate 2 and the second fixed plate 5 are both slidably connected to the pile body 1. The driving assembly includes a bidirectional screw 9 and a connecting rod 10 that are rotatably connected to the pile body 1, a first gear 11 connected to the bidirectional screw 9, and a second gear meshing with the first gear 11 and connected to the connecting rod 10. The first fixed plate 2 is located at both ends of the bidirectional screw 9 and is threadedly connected to the bidirectional screw 9. The connecting rod 10 is located on both sides of the bidirectional screw 9. The connecting rod 10 is provided with threads that are threadedly connected to the second fixed plate 5. The first gear 11 and the second gear are both bevel gears. The bidirectional screw 9 is provided with a worm gear. The pile body 1 is rotatably connected with a driving rod 7. A driving head 6 and a worm meshing with the worm gear are respectively provided at both ends of the driving rod 7, so as to facilitate the driving of the bidirectional screw 9 to rotate.

[0021] Working principle: After drilling a hole on the seabed at a predetermined location, insert the device into it. Figure 1 As shown, the baffle plate cooperates with the pile body 1 to retain part of the soil at the bottom end of the inner side of the pile body 1 and compact it through the baffle plate. The excess seawater is discharged from the drainage groove. The plug plate 3 can be inserted into the retained soil and increase the contact area between the device and the soil. The fixing thorn 4 is inserted into the soil. The sleeve tool is put on the driving head 6 and then rotated forward, as shown in FIG. Figure 4As shown, the driving head 6 drives the worm to rotate through the driving rod 7, and the worm drives the bidirectional lead screw 9 to rotate through the worm wheel. The bidirectional lead screw 9 makes the two first fixed plates 2 move away from each other and drives the first gear 11 to rotate. The first gear 11 drives the connecting rod 10 to rotate through the second gear. The connecting rod 10 drives the second fixed plate 5 to extend out of the pile body 1 through the thread. The first fixed plate 2 and the second fixed plate 5 drive the limit plate 8 to be inserted into the soil. Compared with the prior art, the surface of this device is more complex, the force between the device and the seabed is greater, and the fixing effect is good. Due to the unidirectionality of the worm and worm wheel transmission, the bidirectional lead screw 9 can be prevented from driving the worm wheel to rotate by itself, and then the wind turbine set can be fixed to the pile body 1.

In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
