Technical Field

[0001] The utility model relates to the technical field of offshore wind power engineering, and particularly relates to a deep-water cage structure for an offshore wind farm. Background Technique

[0002] An offshore wind farm refers to offshore wind power with a water depth of about 10 meters. Compared with onshore wind farms, the advantages of offshore wind farms are mainly that they do not occupy land resources, are basically not affected by topography and landforms, have higher wind speeds, richer wind energy resources, larger single-unit capacities of wind turbines (3 - 5 MW), higher annual utilization hours, and the integrated development of offshore wind power and marine ranching is a hot topic, which will realize the three-dimensional development of marine space resources and make full use of marine resources.

[0003] After retrieval, in the application with the patent application number 202220099060.3, a fixed deep-water cage structure for an offshore wind farm is disclosed, which includes a pile foundation, a cage and a feeding assembly. The pile foundation is used to be fixed to the seabed surface, the cage is arranged on the pile foundation, the feeding assembly includes a feeding pipe and a float, the float is used to float on the sea surface, one end of the feeding pipe is connected to the cage, and the other end is connected to the float, which is used to feed the cage.

[0004] Although the fixed deep-water cage structure for the offshore wind farm is provided with a feeding pipe and a float, and can feed and oxygenate the cage through the feeding pipe above the sponge, the surface of the cage of this fixed deep-water cage structure for the offshore wind farm is easily attached by organisms in the sea, which then leads to the blockage of the cage, and it is difficult to discharge the fish feces and food residues in the cage.

[0005] Therefore, we propose a deep-water cage structure for an offshore wind farm. Content of the Utility Model

[0006] Aiming at the deficiencies of the prior art, the utility model provides a deep-water cage structure for an offshore wind farm, which solves the problems that the surface of the cage of the existing device is easily attached by organisms in the sea, which then leads to the blockage of the cage, and it is difficult to discharge the fish feces and food residues in the cage.

[0007] To achieve the above purposes, the utility model is realized through the following technical solutions: A deep-water cage structure for an offshore wind farm includes an annular cylinder with uniformly distributed circular holes penetrating through the side wall, and a pile foundation is arranged at the bottom of the annular cylinder;

A hose communicated with the air inlet holes is fixedly installed on the bottom surface of the cover plate. The bottom end of the hose is fixedly installed with a cleaning ring movably sleeved on the outer surface of the annular cylinder.

[0010] Preferably, a brush hair in contact with the surface of the annular cylinder is fixedly installed on the inner ring of the cleaning ring. Both the cleaning ring and the brush hair are made of plastic material. The diameter of the cleaning ring is the same as that of the cover plate. Among them, the sea water is increased by the booster pump, and then the sea water in the cover plate passes through the filtering holes and the air inlet holes and enters the hose. Then the sea water pressure in the hose increases, which can straighten the hose floating in the sea water, and then push the cleaning ring and the brush hair downward, and then clean the marine organisms attached to the surface of the annular cylinder through the brush hair.

[0011] Preferably, feeding holes located inside the annular partition and uniformly distributed are opened in the middle of the bottom surface of the cover plate. The feeding holes are communicated with the inside of the annular cylinder. The top end of the conveying pipe is threadedly sleeved with a pipe cap. Among them, fish food is put into the conveying pipe. Under the action of the booster pump, the fish food can be conveyed to the inside of the cover plate through the conveying pipe, and then the fish food passes through the feeding holes and enters the inside of the annular cylinder.

[0012] Preferably, the bottom plate is detachably installed on the bottom surface of the annular cylinder through bolts. Through holes uniformly distributed are opened on the bottom surface of the bottom plate. Among them, it is convenient to detach the bottom plate, and then capture the fish inside the annular cylinder.
