A floating wind turbine Technical Field

[0001] The present invention relates to the technical field of offshore power generation, and in particular to a floating wind turbine. Background Art

[0002] Floating wind turbines differ from traditional fixed offshore wind turbines in that they utilize a floating foundation instead of a fixed one, allowing them to "float" on the water. Existing floating wind turbines only provide wind power generation and related auxiliary functions, lacking other features. This reduces their efficiency. Improving their utilization without changing their basic functionality remains a pressing technical challenge for those skilled in the art. Summary of the Invention

[0017] Optionally, in the above-mentioned floating wind turbine, the number of the floating columns is M, one of the M floating columns serves as a main column, and the other floating columns serve as auxiliary columns. The tower is mounted on the main column, and the auxiliary columns are rigidly connected to the main column.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0032] After research, the applicant found that the floating body of the floating wind turbine has no other use except providing buoyancy. Therefore, in order to improve the utilization rate of the floating wind turbine, increase the economic value of the floating wind turbine, and enable large-scale and low-cost development of deep-sea wind power, the applicant has developed a fusion development model for floating wind turbines. This development model is named the wind-fishing fusion model. Under this model, the floating wind turbine has both wind power generation functions and offshore aquaculture functions.

[0033] If a fish cage is hung on a floating structure for aquaculture, it would increase the hydrodynamic forces, resulting in heavy loads on the overall structure, making it difficult to clean the net if marine organisms become attached, and causing losses if the net is damaged, allowing fish to escape. Therefore, after further consideration, the applicant proposed constructing a fish farming tank on the floating columns to cultivate seafood, such as fish, shrimp, and crabs.

[0034] Specifically, referring to FIG. 1 , FIG. 2 and FIG. 3 , the floating wind turbine disclosed in the embodiment of the present application may include:

[0035] Wind turbine 1, tower 2, floating column 3, mooring chain 6 and anchor (not shown);

[0036] The wind turbine 1 is fixed to the first end of the floating column 3 through the tower 2;

[0037] The second end of the floating column 3 is fixed to the anchor via the mooring chain 6;

[0038] The floating column 3 is a hollow structure, and an inlet and outlet are provided on the side wall of the floating column 3. There is a breeding equipment inside the hollow structure, and the breeding equipment can be fish and shrimp breeding equipment, aquatic plant breeding equipment or other breeding equipment. These breeding equipment are fixed to the bottom or side of the hollow structure of the floating column 3.

[0039] The floating column 3 is provided with an inlet and outlet water circuit system 301 that is in communication with the outside. A water pump is provided in the inlet and outlet water circuit system 301. The water pump can be used to pump out the water in the floating column 3, or to pump the external seawater into the floating column 3. The first end 3011 of the inlet and outlet water circuit system 301 is located in the hollow structure of the floating column 3. The part of the inlet and outlet water circuit system 301 located inside the floating column 3 can be fixed to the inner wall of the floating column 3 by a fixing member and extend toward the bottom of the floating column 3, close to the bottom of the hollow structure. At this time, when the water pump pumps out the water inside the floating column 3, it will also pump out the impurities settled at the bottom of the hollow structure of the floating column 3, thereby improving the water quality of the aquaculture site. The second end 3012 of 01 is located on the outside of the floating column 3 and extends along the axis of the floating column 3 to the second end of the floating column 3 (the bottom of the floating column 3). The part of the inlet and outlet water circuit system 301 located on the outside of the floating column 3 is fixed to the outer wall of the floating column 3 by a fixing part, and the second end of the inlet and outlet water circuit system 301 is adjacent to the second end of the floating column 3. Under normal conditions, the second end of the inlet and outlet water circuit system 301 is located below the sea level. The sea level refers to the water surface in Figure 2. When the water pump 8 in the inlet and outlet water circuit system 301 rotates forward, the water inside the floating column 3 can be pumped out to the outside. When the water pump 8 in the inlet and outlet water circuit system 301 rotates reversely, the external water can be pumped into the inside of the floating column 3.

[0040] In the above scheme, the floating column 3 is a hollow structure, which can be used as a breeding site. For example, seafood such as fish, shrimp, and crab can be cultured in this area. This method not only increases the economic benefits of the floating wind turbine, but also allows the center of gravity of the floating column 3 to be maintained near the bottom of the floating column 3 by filling water in the hollow area for breeding operations, thereby ensuring the stability of the floating column 3 and preventing it from shaking violently. In addition, in order to prevent the water quality inside the floating column 3 from being too poor, which may cause the death of the cultured animals, a water inlet and outlet is provided on the floating column 3. The loop system 301 controls the water pump 8 in the water inlet and outlet loop system 301 to rotate forward when the water quality inside the floating column 3 is poor or the water level inside the floating column 3 is high (for example, the lower limit of the water level inside the floating column 3 is 1 / 3 of the floating column, and the upper limit is 1 / 2 of the floating column), so as to extract the water from the floating column 3. When the water level inside the floating column 3 is low, the water pump 8 in the water inlet and outlet loop system 301 is controlled to rotate reversely to send seawater with better external water quality into the floating column 3, thereby providing a stable and excellent water quality environment for the aquaculture.

[0041] In the technical solution disclosed in the above embodiment of the present application, by setting the floating column 3 as a hollow structure, aquaculture equipment is arranged inside the hollow structure and aquaculture operations are carried out. This method can not only increase the stability of the floating column 3, but also improve the economic benefits of the floating wind turbine, thereby further improving the utilization rate of the floating wind turbine.

[0042] In this solution, in order to facilitate users to feed the cultured animals in the floating column 3, a feeding port 9 can be provided on the floating column 3. The feeding port 9 is provided with a cover plate. The cover plate can be made of a transparent material to allow sunlight to enter the hollow area. Under normal conditions, the feeding port 9 is blocked by the cover plate to prevent birds from entering to steal the cultured animals. When feeding is needed, the cover plate can be opened and food can be put into the floating column 3.

[0043] In the technical solution disclosed in this embodiment, the feeding port 9 is located above the waterplane 4 of the floating column 3. Under normal conditions, the waterplane 4 is flush with the water surface to prevent seawater from entering the interior of the floating column 3 through the feeding port. In addition, a climbing ladder can be provided below the feeding port 9 to facilitate users climbing to the feeding port 9.

[0044] In the technical solution disclosed in this embodiment, when the user feeds, the boat may collide with the floating column 3, or the floating column 3 may collide with other hard objects, which may cause the floating column 3 to be leaked, thereby allowing seawater to flow into the interior of the floating column 3, so that the floating column 3 no longer plays the role of supporting the wind turbine 1. In response to this, in this solution, first, a buffer layer can be covered on the outside of the floating column 3, and secondly, the inside of the floating column 3 can be divided into multiple sub-areas, and the sides of the multiple sub-areas are sealed and isolated from each other. At this time, when one of the sub-areas is leaked, seawater will only flow into the sub-area, and will not enter other sub-areas, so that the floating column 3 will not lose its function as a whole, thereby improving the reliability of the floating column 3.

[0045] The hollow area of ​​the floating column 3 is divided radially into N sub-areas, each sealed and isolated from the others, where N is a positive integer not less than 2. That is, the bottoms and sides of the N sub-areas are sealed. This arrangement prevents seawater from entering other sub-areas if one sub-area is struck and penetrated by external forces, thereby preventing seawater from entering the interior of the floating column 3 and causing it to lose its support capacity.

[0046] In the technical solution disclosed in this embodiment, a water level sensor can be set inside the floating column 3, and the water level sensor is used to detect the water level in the hollow area of ​​the floating column 3. When the controller detects that the water level in the hollow area is lower than the minimum threshold, the inlet and outlet water circuit system 301 is controlled to replenish water into the floating column 3 to prevent the aquaculture from dying due to the low water level. When the water level inside the floating column 3 is too high, the water inside the floating column 3 is discharged to the outside of the floating column 3 through the inlet and outlet water circuit system 301 to prevent the water level inside the floating column 3 from being too high, causing the waterline of the floating column 3 to be too high, and causing the floating wind turbine to tilt or collapse.

[0047] In the technical solution disclosed in this embodiment, when the hollow area of ​​the floating column 3 is divided into N sub-areas, the inlet and outlet water circuit system 301 has N first ends, each first end corresponds to a sub-area, and each first end has an independent switch control valve, which can be individually controlled by a controller. When the switch control valve is opened, the first end is connected to the second end of the inlet and outlet water circuit system 301. At this time, under the action of the water pump in the inlet and outlet water circuit system 301, the sub-area can be exchanged with the external seawater.

[0048] In the technical solution disclosed in this embodiment, in order to facilitate the detection of water quality in each sub-area, a water quality detector can also be set in each sub-area. The water quality detector can be connected to a controller. The controller determines whether it is necessary to control the sub-area to exchange seawater with the outside based on the output result of the water quality detector.

[0049] In the technical solution disclosed in this embodiment, in order to prevent the dissolved oxygen concentration in the seawater inside the floating column 3 from being too low, which may lead to the death of the aquaculture, an oxygenation circuit may be further provided inside the floating column 3. The air inlet end of the oxygenation circuit is connected to an aerator, and the aerator is used to oxygenate the seawater inside the floating column 3 to increase the dissolved oxygen concentration. The air outlet end of the oxygenation circuit is located in each sub-area inside the floating column 3. The number of the air outlet ends is N, which corresponds one-to-one to each sub-area. In the technical solution disclosed in this embodiment, the aerator can be integrated into the inlet and outlet water circuit system 301. In this case, the inlet and outlet water circuit system 301 also has a third end, which is connected to the aerator. Similarly, an independent switch valve is provided at the third end. In this case, the second end of the inlet and outlet water circuit system 301 can be used as the outlet of the aeration circuit. When oxygenation is required, the switch valve at the third end of the inlet and outlet water circuit system 301 is controlled to open, and the switch valve at the second end of the inlet and outlet water circuit system 301 corresponding to the sub-area to be oxygenated is controlled to open, and the aerator is started to oxygenate the seawater in the sub-area. During oxygenation, the switch valve at the first end of the inlet and outlet water circuit system 301 can be closed to prevent gas from overflowing through the first end of the inlet and outlet water circuit system 301 during the oxygenation process.

[0050] Furthermore, considering that some farmed animals require lighting, in this solution, a lighting area can be provided on the floating column 3. The lighting area is provided on the side wall of the floating column 3. The lighting area is used to allow light outside the floating column 3 to enter the interior of the floating column 3. The lighting area can be covered with a transparent protective cover (such as transparent glass or transparent plastic plate) or a mesh cover to prevent birds from entering the floating column 3 and stealing the farmed animals. Of course, a lighting system can also be provided on the top of the hollow area of ​​the floating column 3 to provide light for the farmed animals. The lighting system can be controlled by the controller.

[0051] In the technical solution disclosed in this embodiment, the number of floating columns 33 in each floating wind turbine can be designed according to user needs. In this solution, the number of the floating columns 33 is M, one of the M floating columns 33 serves as a main column, and the other floating columns 33 serve as auxiliary columns. The tower 22 is installed on the main column, and the auxiliary columns are rigidly connected to the main column. M is a positive integer not less than 1; for example, in this solution, the value of M can be 3, that is, each floating wind turbine can have 3 floating columns 33. More specifically, referring to Figure 1, the three floating columns 33 can be distributed in the form of an equilateral triangle on the horizontal plane. One of the three floating columns 33 serves as the main column, and the other two floating columns 33 serve as auxiliary columns. The three floating columns 33 are rigidly connected by connecting parts. Through these floating columns 33, the wind turbine 1 can float stably on the water. Of course, the value of M may also be 4 or 5 or other numbers, and the structure of each floating column 3 may be the same.

[0052] In the technical solution disclosed in this embodiment, two adjacent floating columns 3 in a floating wind turbine can be connected by a roll-stabilizing water tank. An internal circulation pipe 7 is disposed within the roll-stabilizing water tank. The ends of the internal circulation pipe 7 are located in the hollow areas of different floating columns 3. An internal circulation water pump 8 is disposed within the circulation pipe. When strong winds and high waves cause the floating wind turbine to yaw, and the yaw of the center of gravity of the nose causes the center of gravity of the entire floating wind turbine to shift, the roll-stabilizing water tanks between the floating columns 3 can be used to adjust the draft of each floating column 3, ensuring that the center of gravity of the floating wind turbine remains within the area enclosed by the M floating columns 3, preventing the floating wind turbine from collapsing. The draft refers to the depth of the floating columns 3 below the water surface. The deeper the floating columns 3 are below the water surface, the higher the draft of the floating columns 3. For example, in this solution, the controller detects the draft water level of each floating column 3, and then calculates the center of gravity position of the floating wind turbine based on the draft water level. When the center of gravity position deviates from the standard position, the internal circulation pipe 7 is used to adjust the water level height in each floating column 3 through internal circulation under the control of the controller to adjust the draft water level of each floating column 3, thereby correcting the center of gravity position of the floating wind turbine to prevent the center of gravity of the floating wind turbine from deviating excessively. This process can be understood as follows: when the center of gravity of the floating wind turbine deviates from the standard position, the water in the hollow area of ​​the floating column 3 with the highest draft water level needs to be dispatched to the floating column 3 with the lowest draft water level. By adjusting the water volume in the central control area of ​​each floating column 3, the draft water level of the floating column 3 is adjusted, so that the center of gravity of the floating wind turbine falls into the area surrounded by the M floating columns 3. The area can also be a standard area in the area surrounded by the M floating columns 3. The standard area has the same center position as the area surrounded by the M floating columns 3. When the center of gravity of the floating wind turbine falls into this area, it indicates that the floating wind turbine is in a stable state. When the center of gravity of the floating wind turbine deviates from this area, it indicates that the floating wind turbine is in an unstable state.

[0053] In the technical solution disclosed in this embodiment, when the floating column 3 has multiple sub-areas, the end of the anti-rolling water tank is connected to one of the sub-areas. During the process of adjusting the center of gravity of the floating column 3, the internal circulation pipe 7 of the anti-rolling water tank will pump water from other floating columns 3 to this sub-area, or pump water from this sub-area to other floating columns 3. During this process, the water level in this sub-area will increase or decrease rapidly, which may cause a large difference in water level between it and other sub-areas in the floating column 3. In this case, the controller can adjust the water level of each sub-area through the sub-area water level adjustment system in the floating column 3, thereby making the water levels of various sub-areas in the same floating column 3 substantially the same. The sub-area water level adjustment system can be integrated into the inlet and outlet water circuit system 301. In this case, each first end of the inlet and outlet water circuit system 301 is provided with a water pump. When the sub-area water level adjustment system is in operation, the second and third ends of the inlet and outlet water circuit system 301 need to be closed. The controller controls the operating state of the water pumps at each second end of the inlet and outlet water circuit system 301 to introduce water from the sub-area with a higher water level into the sub-area with a lower water level. For example, when the water level in sub-area A is the highest and the water level in sub-area B is the lowest, the switch control valves at the second ends corresponding to sub-area A and sub-area B are controlled to open, and the water pump at the second end corresponding to sub-area A is controlled to start. Under the action of the water pump, the water in sub-area A is introduced into sub-area B.

[0054] In the technical solution disclosed in the above embodiment, the water in the hollow area of ​​the floating column 3 not only plays a role in aquaculture, but also plays a role in ballast, thereby making the center of gravity of the floating column 3 downward. Furthermore, the hollow area of ​​the floating column 3 can also prevent sand and gravel from entering. The sand and gravel can further optimize the aquaculture environment of the aquaculture and improve the ballast effect.

[0055] In this embodiment, the controller can determine whether to control the floating wind turbine to enter a dynamic ballast mode based on wind, wave, and current data of the floating wind turbine's environment. In this dynamic ballast mode, the anti-rolling water tank is controlled to keep the center of gravity of the floating wind turbine within the area enclosed by the M floating columns 3. Simultaneously, the sub-area water level adjustment system adjusts the water level of each sub-area so that the water level of each sub-area within the same floating column 3 is substantially the same. This maintains the stability of the floating wind turbine and prevents it from tipping over. Specifically, in this process, the controller is specifically used to: obtain wind, wave and flow data of the environment in which the floating wind turbine is located, determine whether the obtained wind, wave and flow data meets preset conditions; if the preset conditions are not met, it indicates that the floating wind turbine is in a harsh environment; continue to determine whether the change rate of wind force data and / or wind direction data in the wind, wave and flow data is greater than a preset value, and the preset value is a pre-calibrated value; if it is greater than the preset value, it is necessary to control the sub-area water level adjustment system and the internal circulation water pump 8 so that the center of gravity of each floating wind turbine is located in the closed area surrounded by the M floating columns 3, and the water level difference of each sub-area in the floating columns 3 is within an allowable range.

[0056] In the technical solution disclosed in this embodiment, an image collector or an ultrasonic radar or other collection device can also be installed in the hollow area of ​​the floating column 3. The collection device is used to collect the growth status of the cultivated species. The controller can also determine whether the cultivated species has entered the maturity stage based on the collection results of the collection device. When the wind, wave and current data meet the preset conditions and the cultivated species has entered the maturity stage, a prompt signal can be generated and sent to the target object. At this time, after receiving the prompt signal, the target object can control the transport fishing vessel to connect to the floating column 3, transfer the cultivated species in the floating column 3 to the transport fishing vessel, and enter the next stage of the cultivation process. For example, if the cultivated species is fish, the transport fishing vessel can be connected to the fish inlet / outlet on the floating column 3, and the mature fish can be transferred to the fishing vessel through the fish inlet / outlet.

[0057] The controller can control the floating wind turbine to operate in a dynamic ballast mode and a farming mode. Specifically, referring to FIG4 , the controller is used to:

[0058] Step S101: Mode determination.

[0059] In this step, the controller can obtain wind, wave, and current data of the floating wind turbine's environment and, based on the wind, wave, and current data, determine whether the floating wind turbine should enter the dynamic ballast mode or the aquaculture mode. In this embodiment, a preset range of wind, wave, and current data can be pre-calibrated. When the acquired wind, wave, and current data is within this range, it indicates that the floating wind turbine is in a calm environment. In this case, there is no need to adjust the center of gravity of the floating wind turbine, and the floating wind turbine is controlled to enter the aquaculture mode. When the acquired wind, wave, and current data is not within this range, it indicates that the floating wind turbine is in a windy and wavey environment. The controller then determines whether the change in wind force or wind direction exceeds a threshold. If so, it indicates that the center of gravity of the floating wind turbine has shifted significantly, requiring adjustment of the center of gravity of the floating wind turbine and controlling the floating wind turbine to enter the dynamic ballast mode. If the change in wind force or wind direction does not exceed the threshold, it indicates that the center of gravity of the floating wind turbine has shifted slightly, requiring no dynamic ballast mode, and the floating wind turbine is controlled to maintain its current state.

[0060] Step S102: Entering dynamic ballast mode.

[0061] In this step, the floating wind turbine is controlled to enter the dynamic ballast mode. When in the dynamic ballast mode, the center of gravity of the floating wind turbine needs to be adjusted by the anti-roll water tank so that the center of gravity of the floating wind turbine is located within the closed area surrounded by the M floating columns 3 to prevent the floating wind turbine from collapsing. At the same time, the sub-area water level adjustment system needs to be used to keep the water levels of different sub-areas of each floating column consistent to prevent the floating column from tilting due to different water levels in the sub-areas inside the floating column.

[0062] Step S103: Entering the breeding mode.

[0063] In this step, the floating fan is controlled to enter the breeding mode. When in the breeding mode, it is judged whether the breeding products are mature, whether the dissolved oxygen content of the water inside the floating column is sufficient, whether the water quality of the water inside the floating column is qualified, and whether the liquid level inside the floating column is too high or too low.

[0064] For example, in this mode, when it is detected that the aquaculture is mature, a prompt signal can be sent to the target object. At this time, after obtaining the prompt signal, the target object can control the transport fishing boat to connect to the aquaculture inlet and outlet of the floating column 3, and move the aquaculture in the floating column 3 into the transport fishing boat through the aquaculture inlet and outlet. When all the aquaculture are transferred, water is added to the interior of the overlooking column through the water inlet and outlet circuit system, and then aquaculture seedlings are added to the interior of the floating column through the aquaculture inlet and outlet to start the next round of aquaculture.
