A rectangular box 14 with an opening at the bottom is fixedly connected to the top of the pressure sensor 13. A winding shaft 15 is rotatably installed on the inner wall of the rectangular box 14. A soft steel wire rope 11 is wound around the winding shaft 15. A brake motor 16 is fixedly connected to one end of the winding shaft 15 away from the offshore wind power pile foundation 19. A controller 17 is fixedly connected to the bottom of the circular support 12. The controller 17 is electrically connected to the brake motor 16.

The pressure sensor 13 monitors the pressure in real time and transmits the pressure value to the controller 17. The controller 17 is a PLC networked controller. The soft steel wire rope 11 is arranged in the circular support 12, and the soft steel wire rope 11 does not contact the inner side of the circular support 12.

[0022] The offshore wind power foundation anti-scour device provided by the utility model has the following working principle: the conical counterweight sleeve 1 and the annular bottom plate 2 are welded and movably sleeved on the outside of the offshore wind power pile foundation 19, the compression spring 6 in a compressed state elastically tightens the U-shaped plate 7 through the corresponding inner rod 5, and one or more U-shaped plates 7 are squeezed and tightened with the outside of the offshore wind power pile foundation 100 through the corresponding support shaft 8, one-way bearing 9 and anti-skid rubber sleeve 10 in sequence. At this time, one or more anti-skid rubber sleeves 10 surround and tighten the offshore wind power pile foundation 100. The conical counterweight sleeve 1 sinks downward by its own gravity, and the conical counterweight sleeve 1 drives the anti-skid rubber sleeve 10 to rotate on the outside of the offshore wind power pile foundation 100 through the outer tube 4, the inner rod 5, the U-shaped plate 7, the support shaft 8 and the one-way bearing 9 in turn. Since the one-way bearing 9 has the characteristic of single unidirectional rotation, it can guide the conical counterweight sleeve 1 downward in a unidirectional manner after being installed in the appropriate direction. The conical counterweight sleeve 1 drives the annular bottom plate 2 to move down to the mud and sand pressed on the outside of the offshore wind power pile foundation 19, so as to achieve the compaction and protection of the mud and sand. The conical counterweight sleeve 1 is used to withstand the impact force of seawater to achieve the effect of protecting the lower part of the offshore wind power pile foundation 19 from scouring. In addition, the one-way sliding is used in combination with multiple anti-skid rubber sleeves 10 to squeeze the offshore wind power pile foundation 19. Since the one-way bearing 9 can only rotate in one direction and cannot rotate, it can limit the upward movement, so as to prevent the conical counterweight sleeve 1 from floating upward when being scoured, thereby improving the stability effect of compaction and protection of the mud and sand and preventing scouring.When the conical counterweight sleeve 1 sinks to the bottom, it will drive the bottom end of the soft steel wire rope 11 to move downward. After the conical counterweight sleeve 1 sinks to the bottom, the brake motor 16 is started in reverse in advance to drive the winding shaft 15 to reel in the soft steel wire rope 11, so that it is in a vertical state, and then the brake motor 16 is closed. The pressure value for controlling the forward start of the brake motor 16 and the opening of the sound and light alarm 18 is pre-set by the controller 17 according to the monitoring needs. When the bottom mud and sand are accidentally washed away, resulting in a gap with the bottom of the annular bottom plate 2 and unable to continue to be physically supported, the falling pulling force of the conical counterweight sleeve 1 on the soft steel wire rope 11 increases, and the soft steel wire rope 11 drives the rectangular box 14 to increase the squeezing force on the pressure sensor 13 through the winding shaft 15 and the brake motor 16 in turn. The pressure sensor 13 monitors the pressure in real time and transmits it to the controller 17. When the pressure value increases to exceed the preset value, the controller 17 controls the sound and light alarm 1 8 is turned on to give an alarm reminder, and the brake motor 16 is controlled to start forward to drive the reel 15 to release the soft steel wire rope 11. Under the release effect, the conical counterweight sleeve 1 uses its own weight to move down again and drive the annular bottom plate 2 to press and protect the sediment downward, pressing and protecting the sediment at the bottom to support it and reduce the phenomenon of suspended falling force. At this time, the pressure detected by the pressure sensor 13 becomes smaller. When it is lower than the preset value, the controller 17 controls the brake motor 16 and the sound and light alarm 18 to automatically turn off; wherein the controller 17 is a PLC networked controller, which can transmit the alarm information to the background terminal when the received pressure value increases to exceed the preset value, so as to realize the effect of real-time monitoring of whether the sediment sinks and automatically releases and alarms when the sediment sinks, so as to facilitate personnel to know in time when the sediment is accidentally washed down, so as to facilitate personnel to control the lower state, and then facilitate subsequent personnel to deal with and respond, thereby improving the use effect.
