Embodiment 1

[0043] Such as figure 1 , 7 As shown, the upper catch culture device may not completely cover the scour pit. The silt chamber 4 is arranged around the pile foundation 9, and twelve silt chambers 4 are arranged in a circle, and the twelve silt chambers 4 are square and ring-shaped when viewed from above. A certain gap is reserved between every two silt chambers 4, and the silt chambers 4 can be connected by rigid connectors. The cage room 5 is a square ring consistent with the square ring of the sediment chamber 4. The cross-section of net cage cage 7 is square annular, and shape and size are identical with net cage room 5, and are integral structures. The mud storage chamber 8 is a square tube, and the top opening is square, and the top opening size is consistent with the cross-sectional edge size of the net cage cage 7.

Embodiment 2

[0045] Such as Figure 8 As shown, the upper catchment culture device covers the upper part of the scour pit, while the distribution area of ​​the lower mud storage device is smaller than that of the upper catchment culture device; the sediment from the upper catchment culture device does not completely fall into the mud storage Room 8. The silt chamber 4 is arranged around the pile foundation 9, and ninety-six silt chambers 4 are arranged in a week, and the ninety-six silt chambers 4 are square ring-shaped when viewed from above. A certain gap is reserved between every two silt chambers 4, and the silt chambers 4 can be connected by rigid connectors. The cage room 5 is a square ring consistent with the square ring of the sediment chamber 4. Net cage cage 7 is integral structure, and net cage cage 7 cross sections are square ring, and net cage cage 7 cross sections are less than the cross section of net cage room 5. The mud storage chamber 8 is a square tube, and the top op...

Abstract

The invention discloses an offshore wind power scour pit self-repairing device with a micro-ecological breeding function, and belongs to the technical field of offshore wind power engineering. The self-repairing device comprises an upper flow blocking breeding device, a lower mud storage device and a connecting rope. The upper flow blocking breeding device is arranged around the pile foundation and is slightly higher than the upper edge of the scouring pit; the lower mud storage device is located below the upper flow blocking breeding device, arranged in the washing pit and connected with the upper flow blocking breeding device through a connecting rope. The upper flow blocking breeding device comprises floating balls, mooring ropes, seedling breeding transverse rods, a turning plate structure, a sediment chamber and a net cage chamber. The floating ball is connected above the sediment chamber through a cable; the net cage chamber is arranged below the sediment chamber; the seedling-raising cross rod is horizontally arranged at the top of the sediment chamber; the lower sludge storage device comprises a net box cage and a sludge storage chamber, and the sludge storage chamber is arranged below the net box cage. The silt is stored in the breeding device, loss of the silt near the scouring pit is reduced, the stored silt is used for filling the scouring pit, and self-repairing is achieved.

Description

technical field [0001] The invention relates to a self-repairing device for an offshore wind power scour pit with the function of micro-ecological breeding, and belongs to the technical field of offshore wind power engineering. Background technique [0002] With the continuous expansion of the development and utilization of marine energy resources, more and more offshore wind power has emerged. When the basic structure of offshore wind power stands in the ocean, the water flow field near the basic structure will change greatly, a horseshoe vortex will be generated in front, and the flow velocity will increase. When waves encounter the underwater basic structure, diffraction, reflection and Breaking waves etc. These phenomena eventually lead to an increase in the shear stress and sediment transport rate values ​​of the seabed surface at the bottom of the underwater foundation structure, and lead to local scour. However, traditional protection measures such as riprap and san...
