[0028] The detailed description of the embodiments of the present disclosure will be described below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0029] In the present disclosure, the orientation words such as "up, down" used without the opposite description are generally defined as the direction of the drawing surface, and "inner, outer" refers to the inner and outer of the relevant parts. In addition, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0030] In the description of the present disclosure, it also needs to be explained that, unless otherwise explicitly specified and limited, the terms "set", "connected" should be understood broadly, for example, it can be fixedly connected, or detachably connected, or integrally connected, it can be directly connected, or indirectly connected through an intermediate medium, it can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.

[0031] In recent years, offshore wind power has developed rapidly. Offshore wind power is a clean energy with the advantages of large installed capacity, no occupation of land resources, and small pollution. However, single offshore wind turbine has many problems such as large volume of wind turbine foundation and high cost. At present, the nearshore mariculture industry in China has developed for a long time and the technology is relatively mature. However, due to the defects of the ecological structure and the breeding mode of aquaculture, it not only pollutes the ecological environment itself, but also causes certain damage to the ecological system of the nearshore waters.

[0032] Deep sea mariculture refers to fixing mariculture net cages and other facilities in a semi-open or open sea area away from the mainland and deeper than 20m through mooring systems, lifting systems and other equipment technologies, and carrying out feed feeding, mariculture management, fishing and other work through mariculture work ships or mariculture platforms. This mariculture mode has developed rapidly in the past decade. However, due to the problem that deep sea mariculture equipment is far away from the coast and the high cost of power supply, the industrialization development of deep sea mariculture is still restricted. Therefore, more and more people combine offshore wind power with mariculture to realize the two functions.

[0033] However, in the current wind-fish combined wind turbine foundation assembly, the mariculture net cage is fixedly installed on the wind turbine foundation assembly and cannot be disassembled for cleaning or replacement, which is inconvenient to use. For example, in the patent with the application number 201810809883.9 and the name of a fishery net cage and floating wind turbine foundation combined structure and construction method, the fishery net cage and the wind turbine foundation combined structure are connected in a fixed manner.

[0034] Therefore, as shown in the figure, one aspect of the present disclosure provides a wind-fish combined wind turbine foundation assembly, which comprises a floating foundation 1 and a mariculture net cage 2.

[0035] The floating foundation 1 is used for floating on the sea surface. The floating foundation 1 is used for installing a tower 33 of a wind turbine. The floating foundation 1 is provided with a containing space. The mariculture net cage 2 is arranged in the containing space.

[0036] The culture net cage 2 comprises a cage body 21 for culturing marine organisms, a floating component 22 connected to the cage body 21 for controlling the cage body 21 to float or sink, and a connecting member 23 connected at one end to the floating component 22 and / or the cage body 21 and connected at the other end to the floating foundation 1.

[0037] The floating foundation 1 can float on the sea surface and can float in the deep sea, and the tower 33 of the wind turbine can be installed on the floating foundation 1 to fix the tower 33 of the wind turbine. The culture net cage 2 can be located in the deep sea by being connected to the floating foundation 1, and deep-sea culture can be achieved.

[0038] The cage body 21 of the culture net cage 2 is used to form a culture space, and it can be understood that the water of the sea can enter the cage body 21 to achieve natural environment culture, and the marine organisms can move freely in the cage body 21.

[0039] In the above technical solution, the accommodating space is arranged in the floating foundation 1, which can conveniently accommodate the culture net cage 2, so that the culture net cage 2 can be conveniently removed or reinstalled, and maintenance or replacement of the culture net cage 2 can be achieved. The floating component 22 can be arranged to control the cage body 21 to float or sink, so that the cage body 21 can be sunk into the water or floated to the water surface, which is convenient for lifting, maintenance or replacement, and the operation is very convenient. The connecting member 23 can be used to connect the cage body 21 and the floating foundation 1, so that the cage body 21 is fixed in the floating foundation 1 and cannot move randomly, and the cage body 21 and the floating foundation 1 can also be separated, so that the cage body 21 can be maintained or replaced. The wind turbine foundation assembly combines wind power and fishery culture, has low cost, realizes two functions, and can conveniently pull out the cage body 21 to reduce the cost of salvage.

[0040] Optionally, in an embodiment of the present disclosure, the floating component 22 comprises a float pipe 221 and a counterweight 224, and the float pipe 221 and the counterweight 224 are respectively connected to the cage body 21. The float pipe 221 is provided with an air bag, and the air bag is arranged to be inflatable or deflatable. The float pipe 221 and the counterweight 224 can be respectively arranged to provide buoyancy or sinking force, so that the cage body 21 can float or sink. In addition, the counterweight 224 can improve the balance stability of the cage body 21 in the water, and can increase the wind and wave resistance.

[0041] The air bag in the float pipe 221 can control the size of the buoyancy by being inflated or deflated. When the air bag in the float pipe 221 is inflated, the float pipe 221 generates an upward buoyancy. When the upward buoyancy is greater than the gravity of the counterweight 224 and the box body 21, the box body 21 can be driven to move upward. When the air bag in the float pipe 221 is deflated, the float pipe 221 does not generate buoyancy, and the box body 21 sinks under the action of the counterweight 224.

[0042] The float pipe 221 can be a hollow composite non-metal pipe with high hardness and corrosion resistance, and the inside of the float pipe 221 is filled with air bags. In some examples, the float pipe 221 is a hollow pipe, and the air bags are in the float pipe 221. The air bags can be a whole bag body or multiple bag bodies.

[0043] Optionally, in an embodiment of the present disclosure, the outer wall of the float pipe 221 is provided with a through hole in communication with the inside of the float pipe 221, and the through hole is used for water flow. The through hole can make water enter or exit the float pipe 221, and is more conducive to controlling the size of the buoyancy.

[0044] It can be understood that when the air bag in the float pipe 221 is inflated, the air bag bulges and pushes the water in the float pipe 221 out of the through hole, which is conducive to the upward floating. When the air bag in the float pipe 221 is deflated, seawater can enter the float pipe 221 through the through hole, increase the weight of the float pipe 221, and be conducive to the sinking of the box body 21. In some examples, the number of through holes can be multiple, and the multiple through holes are arranged along the length direction of the float pipe 221.

[0045] Optionally, in another embodiment of the present disclosure, the outer wall of the float pipe 221 can not be provided with a through hole.

The upward float pipe 222 is connected to the top of the box body 21, and the downward float pipe 223 is connected to the bottom of the box body 21. By such arrangement, the buoyancy can be better controlled, so that the top of the box body 21 and the bottom of the box body 21 can both generate buoyancy, which is more conducive to driving the upward floating or sinking of the box body 21.

[0047] Optionally, in another embodiment of the present disclosure, the float pipe 221 can be connected to the top of the box body 21, or the float pipe 221 can be connected to the bottom of the box body 21, or the float pipe 221 can be connected to the outer side wall of the box body 21.

[0048] Optionally, in one embodiment of the present disclosure, the upper floating pipe 222 and the lower floating pipe 223 are both configured as circular ring structures, the upper floating pipe 222 extends along the circumferential edge of the top of the box 21, and the lower floating pipe 223 extends along the circumferential edge of the bottom of the box 21. By so arranging, a uniform buoyancy can be generated, so that when the box 21 is driven to float, the balance of the box 21 can be maintained, and the box 21 can be prevented from tilting. It can be understood that the axes of the upper floating pipe 222 and the lower floating pipe 223 coincide with the axis of the box 21 in the vertical direction, and the balance of the box 21 when floating or sinking can be better maintained.

[0049] Optionally, in another embodiment of the present disclosure, the upper floating pipe 222 and the lower floating pipe 223 can be straight pipes, and the number of the upper floating pipe 222 and the lower floating pipe 223 is multiple. The multiple upper floating pipes 222 and the multiple lower floating pipes 223 can be arranged in parallel and side by side, or can be connected end to end with each other.

[0050] Optionally, in one embodiment of the present disclosure, the circumference of the circumferential edge of the top of the box 21 is greater than the circumference of the circumferential edge of the bottom of the box 21, and the diameter of the upper floating pipe 222 is greater than the diameter of the lower floating pipe 223. By so arranging, the center of gravity of the box 21 is close to the lower position of the box 21, the balance of the box 21 can be improved, the ability to resist waves can be increased, and the stability of the box 21 when floating or sinking can be improved. It can be understood that the upper floating pipe 222 is a large circular ring, the lower floating pipe 223 is a small circular ring, and the box 21 is a reverse circular table structure.

[0051] Optionally, in another embodiment of the present disclosure, the diameters of the upper floating pipe 222 and the lower floating pipe 223 can be the same, and the box 21 can be a cylinder.
