Embodiment

[0021] As Figure 1 、 Figure 2 And Figure 3 Shown;

[0022] An anti-scouring device for an offshore wind power foundation includes a left bearing sleeve 1 and a right bearing sleeve 2 that are buckled with each other. The inner sides of the left bearing sleeve 1 and the right bearing sleeve 2 are evenly spaced with mounting seats 3. The upper pressure rod 4 and the lower pressure rod 5 are symmetrically arranged up and down inside the mounting seat 3. One end of the upper pressure rod 4 and the lower pressure rod 5 are both rotatably provided with a pressing plate 6 that abuts against the wind power pile foundation, and an adjustment component 7 is inserted between the upper pressure rod 4 and the lower pressure rod 5; the outer sides of the left bearing sleeve 1 and the right bearing sleeve 2 are evenly spaced with first load-bearing rods 8, and a second load-bearing rod 9 is provided between each two groups of first load-bearing rods 8 that are close to each other. The first load-bearing rod 8 and the second load-bearing rod 9 are both detachably provided with a protection plate 10. The left bearing sleeve 1 and the right bearing sleeve 2 are both semi-circular structures, and the left bearing sleeve 1 and the right bearing sleeve 2 are detachably connected by a pin.

[0023] It should be noted that: in this embodiment, there are at least four mounting seats 3, and the left bearing sleeve 1 and the right bearing sleeve 2 are closely attached and cannot rotate.

[0024] In this embodiment: The bearing sleeves are installed by being buckled with each other, which is convenient for disassembly and assembly. Moreover, the upper and lower groups of pressure rods can be extruded through the adjusting component 7, so as to be quickly fixed on the wind power pile foundation. At the same time, the protective plate 10 in this embodiment can be detachably installed, which is convenient for the maintenance of the device and the replacement of vulnerable parts, thereby improving the overall service life of the device.

[0025] As Figure 4 shown;

[0026] In an alternative embodiment, the adjusting component 7 includes a threaded rod 701 passing through the upper pressure rod 4 and the lower pressure rod 5. Adjusting nuts 702 and limit nuts 703 are respectively provided at the top and bottom of the threaded rod 701. Long strip holes that are vertically aligned are provided in the middle parts of the upper pressure rod 4 and the lower pressure rod 5.

[0027] In this embodiment: The diameter of the long strip hole is larger than the diameter of the threaded rod 701 and smaller than the minimum outer diameters of the adjusting nut 702 and the limit nut 703. The long strip hole can ensure that the adjusting nut 702 drives the upper pressure rod 4 and the lower pressure rod 5 to approach each other.

[0028] In an alternative embodiment, one side of the pressing plate 6 is an arc-shaped structure, and the pressing plate 6 is provided with a protective pad that abuts against the wind power pile foundation. On the one hand, the protective pad plays a buffering role, and on the other hand, it can prevent extrusion damage to the wind power pile foundation.

[0029] In an alternative embodiment, the length of the first bearing rod 8 is greater than the length of the second bearing rod 9, and the protective plate 10 is detachably fixed to both the first bearing rod 8 and the second bearing rod 9 by screws.

[0030] In this embodiment: Rectangular limit blocks are provided at one ends of both the first bearing rod 8 and the second bearing rod 9. Rectangular grooves that are buckled with the rectangular limit blocks are provided on the protective plate 10, so as to ensure the stability of the installation of the protective plate 10. The bottom of the protective plate 10 is set as an arc-shaped structure, which can effectively avoid vertical scouring.

[0031] It should be noted that by arranging the second bearing rod 9 between the first bearing rods 8, it can be ensured that there is no scouring gap between the protective plates 10, so as to better protect the wind power pile foundation.

[0032] Working principle and usage process of the utility model: First, pass the left bearing sleeve 1 and the right bearing sleeve 2 through the wind power pile foundation and fasten them together with a pin, so that the upper pressure rod 4 and the lower pressure rod 5 are separated up and down and form a triangular structure with the wind power pile foundation. Then, rotate the adjusting nut 702 on the threaded rod 701 in sequence. The adjusting nut 702 and the limiting nut 703 gradually approach until the protective pad on the pressing plate 6 abuts against the wind power pile foundation. At this time, pre-clamping is carried out first. Then, fix the protective plate 10 on the first bearing rod 8 and the second bearing rod 9 respectively with bolts, adjust the up and down position of the bearing sleeve and make the protective plate 10 abut against the ground surface. Finally, continue to rotate the adjusting nut 702 to clamp the pressing plate 6.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
