The inner knob 11 will not be affected by external factors due to the complexity of the seabed environment. The fixed plate 10 will not be adjusted to displace. The connection stability provided by the fixed plate 10 is ensured.

[0030] Preferably, the fixing structure includes the bracket 15, the pressing plate 16, the strip-shaped groove 17, the fitting groove 18, the threaded column 19, the second threaded cylinder 20 and the control block 21. The bracket 15 is arranged on the top of the connecting rod 2. The pressing plate 16 is movably arranged on the top of the bracket 15. The strip-shaped groove 17 is arranged on the side of the pressing plate 16 away from the bracket 15. The fitting groove 18 is arranged on the inner side of the strip-shaped groove 17. The threaded column 19 is arranged on the top of the platform 4. The second threaded cylinder 20 is arranged on the outer side of the threaded column 19. The control block 21 is arranged on the top of the second threaded cylinder 20.

[0031] Through the above scheme, the fixing mechanism is used to complete the installation and fixing of the turf 5.

[0032] Preferably, the connecting mechanism includes the plug block 22, the clamping plate 23, the plug-in groove 24 and the clamping groove 25. The plug block 22 is movably arranged on the side of the outer knob 14. The clamping plate 23 is arranged on the end of the plug block 22 close to the inner knob 11. The plug-in groove 24 is arranged on the side of the inner knob 11. The clamping groove 25 is evenly arranged on the inner side of the plug-in groove 24.

[0036] In this embodiment, preferably, one end of the plug block 22 is fixedly provided with a limiting plate 26, and a spring 27 is sleeved outside the plug block 22 between the limiting plate 26 and the outer knob 14;

[0037] Through the above scheme, the subsequent reset of the plug block 22 is realized through the limiting of the limiting plate 26 and the force of the spring 27;

[0038] In this embodiment, preferably, one side of the fixed plate 10 is fixedly provided with a telescopic rod 28 on one side of the first threaded cylinder 9, and the telescopic end of the telescopic rod 28 is fixedly connected with the mounting block 7;

[0039] Through the above scheme, the telescopic rod 28 is used to provide a limiting effect for the fixed plate 10, so as to ensure that the fixed plate 10 can be displaced with the rotation use of the threaded rod 8;

[0040] The offshore wind power scour protection device of the embodiment is used by first assembling the protective sleeve 1 on the pile to be protected, then assembling two protective sleeves 1 together through the bolts assembled on the connecting ears of the protective sleeve 1, i.e. the protective sleeve 1 is sleeved outside the pile, and at the same time, the grass 5 at the bottom is laid on the seabed where the pile is located, the flow velocity of the seabed is reduced through the bionic grass 6 arranged on the grass 5, the kinetic energy of the sea current is reduced, the probability of forming a vortex is reduced, and the probability of the seabed silt being lifted is reduced, thereby reducing the possibility of the pile being scoured by silt, thereby protecting the pile of the offshore wind power equipment. After the protective sleeve 1 is sleeved, the rotation of the inner knob 11 is used to rotate the driving threaded rod 8, so that the two fixed plates 10 limited by the arrangement of the telescopic rod 28 are moved to press against the pile, thereby ensuring the stability of the device during use and preventing it from easily separating from the pile. When the inner knob 11 is used in particular, the outer knob 14 needs to be held, and the palm is pressed against one end of the insert block 22, so that the other end is embedded in the insert slot 24 on the inner knob 11. At the same time, because the end of the clamping groove 25 close to the clamping plate 23 is an expanded structure, no matter where the clamping plate 23 on the insert block 22 is located, it can be embedded in the clamping groove 25. Therefore, by continuing to rotate the outer knob 14, the inner knob 11 can be driven to rotate and the threaded rod 8 can be driven to rotate, and after the adjustment and use of the fixed plate 10 are completed, the outer knob 14 is loosened, and the insert block 22 is reset and separated from the inner knob 11 under the action of the spring 27. Therefore, through the arrangement of the outer knob 14 and the connecting mechanism, the inner knob 11 will not be affected by external factors due to the complexity of the seabed environment, and the fixed plate 10 will not be adjusted and displaced, thereby ensuring the connection stability provided by the fixed plate 10 and making the protective device have good long-term use effect. The grass 5 and the bionic grass 6 are fixed between the shelves 4 through the pressing effect of the pressing plate 16 during actual application. With long-term use, if damage occurs or maintenance is needed, the rotation of the second threaded cylinder 20 can make the pressing plate 16 lose the pressing fixation of the control block 21. When the orientation of the control block 21 is consistent with the strip-shaped groove 17, the worker can directly open the pressing plate 16 to make it vertical, and then the grass 5 together with the bionic grass 6 can be taken down for subsequent maintenance or replacement, which is simple and convenient, ensures the convenience of subsequent maintenance or replacement of the bionic grass 6, and further improves the actual application effect of the protective device.
