Description

Technical Field

[0001] The utility model relates to the technical field of offshore wind turbine foundations, and particularly relates to an integrated wind turbine foundation. Background Art

[0002] With the vigorous development of wind power technology, offshore wind power devices can be roughly divided into fixed types and floating types according to the method of installing generator sets on the sea. The fixed type is a method of carrying out foundation works on the seabed foundation of the sea with relatively shallow water depth and installing power generation equipment thereon. The floating type is a method of floating the generator set on a floating body on the sea and using mooring to connect the floating body to prevent the floating body from moving.

[0003] Due to the high technical content and large investment cost of wind power, the benefits are relatively low. For this reason, conventional floating wind power foundations integrate wind power generation and fishery to improve the overall income, achieve grid parity for offshore wind power, and provide a good living environment for marine organisms. However, since the floating wind power foundation is only used to support the wind power generation components during installation, the utilization degree of marine resources is relatively low. Content of the Utility Model

[0004] In view of this, the utility model provides an integrated wind turbine foundation to solve the problem of relatively low utilization degree of marine resources.

[0005] The utility model provides an integrated wind turbine foundation, which includes an aquaculture cage, a photovoltaic structure and a wind turbine structure. The aquaculture cage is at least partially located above the sea level in the height direction; the photovoltaic structure is installed on the top of the aquaculture cage; the wind turbine structure is fixedly installed above the aquaculture cage.

[0006] Beneficial effects: By exposing the aquaculture cage at least partially above the sea level in the height direction, and with a relatively large cage area, it can form a "semi-submersible" foundation. Also, by arranging the photovoltaic structure on the top of the aquaculture cage and installing the wind turbine structure above the aquaculture cage, the efficient utilization of the three-dimensional space of the ocean can be realized. At the same time, aquaculture, photovoltaic power generation and wind power generation can be combined to achieve diversified income, thereby improving the overall benefit, and realizing the effective integration and comprehensive utilization of various resources. In addition, in case of power grid outage or other emergencies, photovoltaic power generation and wind power generation can provide necessary power support for the aquaculture cage to ensure the normal progress of aquaculture activities. That is, it realizes the integration of offshore wind power generation, photovoltaic power generation and cage aquaculture functions, realizes the effective utilization of sea area resources, can achieve energy self-sufficiency, realizes the comprehensive utilization of resources, and further increases economic benefits.

[0007] In an alternative embodiment, the integrated wind turbine foundation further includes a connection structure, which includes a first connector and a second connector. Among the first connector and the second connector, one of them is located inside the aquaculture cage, and one end of it along its axis is fixed to the top of the aquaculture cage, and the other end of it along its axis extends towards the bottom wall surface of the aquaculture cage. The other end of the other one along its axis is located outside the aquaculture cage, and the other end of the other one extends into the aquaculture cage, and the other end of the other one is connected to the other end of the one.

[0008] Advantageous effects: By arranging one of the first connector and the second connector on the top of the aquaculture cage, connecting the other one to it and extending it outside the aquaculture cage, and connecting the two, the external force received by the other one can be transmitted to the aquaculture cage. Compared with a single-column foundation, since the area of the cage is relatively large, a semi-submersible structure can be formed. By increasing the waterplane area, stronger anti-overturning performance can be provided for the entire integrated wind turbine foundation, and the phenomenon that the single-column structure has relatively weak anti-overturning ability in the pitching direction can be improved.

[0009] In an alternative embodiment, among the other ends of the first connector and the second connector, one of them is provided with a sliding groove extending along its axis, and the other one is provided with a sliding protrusion extending along its axis. The sliding protrusion is slidably installed in the sliding groove; wherein, the axes of the first connector and the second connector are arranged in parallel.

[0010] Advantageous effects: By providing a sliding groove extending along its axis in one of the other ends of the first connector and the second connector, and a sliding protrusion extending along its axis in the other one, and making the axes of the first connector and the second connector arranged in parallel, during installation, relative sliding of the sliding protrusion and the sliding groove in the axial direction thereof is allowed, providing a certain adjustment space, which can better adapt to aquaculture cages of different sizes, reduce the installation difficulty, and make the installation process more flexible and convenient.

[0011] In an alternative embodiment, the integrated wind turbine foundation further includes a floating box and a pump body. The floating box is installed at the bottom of the aquaculture cage in the height direction. The floating box includes a ballast tank opened inside, an inlet and an outlet communicated with the ballast tank. The ballast tank is used for storing and discharging ballast water. An inlet valve is installed at the inlet, the outlet is located below the inlet, and a drain valve is installed at the outlet; the pump body is fixedly installed on the floating box, and the pump body is used for controlling the ballast water to enter the ballast tank and for controlling the ballast water in the ballast tank to be discharged outside the ballast tank.

[0012] Beneficial effects: By respectively providing an inlet valve and an outlet valve at the water inlet and outlet of the ballast tank opened inside the pontoon, and adding a pump body, it is convenient to control the amount of ballast water entering the ballast tank, thereby realizing flexible adjustment of the draft depth of the integrated wind turbine foundation as a whole; at the same time, through the setting of the pontoon, the additional mass and additional rotational inertia of the entire integrated wind turbine foundation can be increased, and the damping of the overall structure can be increased. In addition, due to the high height of the wind turbine assembly, at a certain wind speed, the wind tilting moment is large, which can easily cause a large pitch phenomenon. By adding a pontoon, the overall structure is constructed into a semi-submersible-semi-column structure, which improves the ability of the single-column fan to resist pitch and roll, and improves the overall viscous damping, improves the overall motion performance in pitch automaticity, and adjusts its resonance period.

[0013] In an optional embodiment, the integrated wind turbine foundation further includes an anchor chain, one end of the anchor chain is connected to the other end of the first connector and the second connector along their axial direction, and the other end of the anchor chain is fixed to the seabed surface.

[0014] Beneficial effects: By adding anchor chains, the wind turbine foundation can be fixed to the seabed, improving the degree of displacement or overturning due to special sea conditions such as wind, waves, tides, etc., ensuring that the wind turbine can operate stably under extreme weather conditions.

[0015] In an optional embodiment, a plurality of anchor chains are provided, and the plurality of anchor chains are arranged at intervals in a circumferential direction around the other of the first connecting member and the second connecting member.

[0016] Beneficial effect: By providing multiple anchor chains, the load on the wind turbine foundation can be dispersed to the sea, reducing the stress on a single anchor chain, thereby improving the bearing capacity and stability of the overall wind turbine foundation.

[0017] In an optional embodiment, the wind turbine structure includes a tower, a generator and a wind wheel, wherein one end of the tower along its axis is installed on the top of the breeding cage, and the other end of the tower along its axis extends in a direction away from the sea level; the generator is installed at the other end of the tower along its axis; the hub of the wind wheel is connected to the rotor of the generator through a transmission shaft, or the hub of the wind wheel is connected to the rotor of the generator through a transmission shaft and a gear structure.

[0018] Beneficial effects: By installing the tower barrel of the wind turbine structure on the top of the aquaculture cage, installing the generator on the tower barrel, and then drivingly connecting the wind wheel to the rotor of the generator, the wind energy obtained by the wind wheel can be converted into electrical energy after passing through the transmission shaft and the gear structure, providing power supply for the aquaculture cage or other installations on the sea, reducing the dependence on the external power grid, and improving the self-sufficiency ability of energy supply; at the same time, it is convenient for maintenance personnel to centrally manage the wind turbine and the aquaculture cage, improving the maintenance efficiency.

[0019] In an alternative embodiment, the aquaculture cage includes a support frame, and the support frame is enclosed to form a cylindrical cage.

[0020] Beneficial effects: By providing a support frame in the form of a cylindrical cage, the cage is more stable in the wind and waves, reducing the shaking and deformation caused by wave impact, and ensuring the long-term stable operation of the cage.

[0021] In an alternative embodiment, the photovoltaic structure includes solar panels, the solar panels are laid on the top of the aquaculture cage, there are multiple solar panels, and the multiple solar panels are spliced to form a disc structure.

[0022] Beneficial effects: By laying multiple solar panels on the top of the aquaculture cage, solar radiation can be received, the light energy can be converted into electrical energy, and the overall weight can be increased, which helps to resist the influence of bad weather such as wind and waves.

[0023] In an alternative embodiment, an opening is also provided at the top of the aquaculture cage, and the solar panel is installed at the opening so that the solar panel, the side wall surface of the aquaculture cage and the top wall surface of the floating box enclose to form an aquaculture chamber.

[0024] Beneficial effects: By providing an opening at the top of the cage and installing the solar panel at the opening, there is no need to occupy additional land or sea area resources, and the space at the top of the cage is effectively utilized. BRIEF DESCRIPTION OF THE DRAWINGS

For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0042] In addition, the technical features involved in different embodiments of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0043] The following Figures 1 to 4 is combined to describe the embodiments of the present utility model.

[0044] According to an embodiment of the present utility model, an integrated wind turbine foundation is provided.

[0045] Specifically, as Figure 1 shown, the integrated wind turbine foundation includes an aquaculture cage 1, a photovoltaic structure 2, and a wind turbine structure 3. The aquaculture cage 1 is at least partially located above the sea level 71 in the height direction; the photovoltaic structure 2 is installed on the top of the aquaculture cage 1; the wind turbine structure 3 is fixedly installed above the aquaculture cage 1.

[0046] By using the technical solution of this embodiment, by exposing the aquaculture cage 1 at least partially above the sea level 71 in the height direction, its cage area is large, which can form a "semi-submersible" foundation. Also, by arranging the photovoltaic structure 2 on the top of the aquaculture cage 1 and installing the wind turbine structure 3 above the aquaculture cage 1, the efficient utilization of the three-dimensional space of the ocean can be achieved. At the same time, aquaculture, photovoltaic power generation, and wind power generation can be combined to achieve diversified income, thereby improving its overall efficiency, and realizing the effective integration and comprehensive utilization of various resources. In addition, in case of power grid outage or other emergencies, photovoltaic power generation and wind power generation can provide necessary power support for the aquaculture cage 1 to ensure the normal progress of aquaculture activities. That is, it realizes the integration of offshore wind power generation, photovoltaic power generation, and cage aquaculture functions, realizes the effective utilization of sea area resources, can achieve energy self-sufficiency, realizes the comprehensive utilization of resources, and further increases economic benefits.

[0047] AsFigure 1 , Figure 3 and Figure 4 As shown in Figure 1 , Figure 3 and Figure 4 , the integrated wind turbine foundation further includes a connection structure 4, which includes a first connecting member 41 and a second connecting member 42. Among the first connecting member 41 and the second connecting member 42, one of them is located inside the aquaculture cage 1, and one end of it along its axial direction is fixed to the top of the aquaculture cage 1. One end of it along its axial direction extends towards the bottom wall surface of the aquaculture cage 1. The other end of the other one along its axial direction is located outside the aquaculture cage 1, and the other end of the other one extends into the aquaculture cage 1, and the other end of the other one is connected to the other end of the one.

[0048] With the technical solution of this embodiment, by arranging one of the first connecting member 41 and the second connecting member 42 on the top of the aquaculture cage 1, the other one is connected to it and extends outside the aquaculture cage 1, and the two are connected, the external force received by the other one can be transmitted to the aquaculture cage 1. Compared with the single-column foundation, since the area of the cage is relatively large, a semi-submersible structure can be formed. By increasing the waterplane area, stronger anti-overturning performance can be provided for the entire integrated wind turbine foundation, and the phenomenon that the single-column structure has relatively weak anti-overturning ability in the pitching direction can be improved.

[0049] It can be explained that in this embodiment, among the other ends of the first connecting member 41 and the second connecting member 42, one of them is provided with a sliding groove 43 extending along its axial direction, and the other one is provided with a sliding protrusion 44 extending along its axial direction. The sliding protrusion 44 is slidably installed in the sliding groove 43; wherein, the axes of the first connecting member 41 and the second connecting member 42 are arranged in parallel.

[0050] With the technical solution of this embodiment, by arranging one of the other ends of the first connecting member 41 and the second connecting member 42 with a sliding groove 43 extending along its axial direction, and the other one with a sliding protrusion 44 extending along its axial direction, and making the axes of the first connecting member 41 and the second connecting member 42 arranged in parallel, during installation, the sliding protrusion 44 and the sliding groove 43 are allowed to slide relative to each other in their axial directions, providing a certain adjustment space, which can better adapt to aquaculture cages 1 of different sizes, reduce the installation difficulty, and make the installation process more flexible and convenient.

[0051] Preferably, in this application, the first connecting member 41 is provided with a sliding groove 43, and the first connecting member 41 is installed inside the aquaculture cage 1, and the second connecting member 42 is provided with a sliding protrusion 44.

[0052] Similarly, the number of the sliding grooves 43 and the sliding protrusions 44 is not specifically limited, as long as the sliding protrusions 44 and the sliding grooves 43 can be arranged in one-to-one correspondence and can be slidably arranged during installation.

[0053] Preferably, a total of three sliding grooves 43 are provided, and at this time, three sliding protrusions 44 are also provided.

[0054] Similarly, in the present application, it is preferably arranged that the axes of the first connecting member 41 and the second connecting member 42 are collinear, making the sliding process smoother, avoiding friction caused by misalignment, reducing the resistance of its movement, and helping the first connecting member 41 and the second connecting member 42 to move smoothly along the predetermined trajectory during installation.

[0055] In addition, the relationship between the size of the sliding groove 43 and the size of the sliding protrusion 44 is not specifically limited.

[0056] Preferably, the length of the sliding groove 43 along its axis is greater than or equal to the length of the sliding protrusion 44 along its axis. With such a setting, it is convenient to adjust the water intake of the overall structure in a timely manner; when encountering special sea conditions such as wind waves and tides, the sliding connection design allows for a small relative sliding in the axial direction, thereby maintaining the stability of the fan and the photovoltaic structure 2.

[0057] It should be noted that in the above embodiment, the lower limit of the downward movement of the aquaculture cage 1 should be that the top of the aquaculture cage 1 is submerged in the sea level, and at this time, the photovoltaic structure 2 should be above the sea level.

[0058] Of course, when the adjustment is in place, a fastening structure can be used to fix it. For example, the cross-section of the sliding protrusion 44 is in an "H" shape, and the corresponding sliding groove is adapted to its shape. During installation, the sliding protrusion 44 is placed inside the sliding groove 43, and by forming an "H" structure, circumferential positioning of the sliding protrusion 44 is achieved. At the same time, the first connecting member 41 has a certain elasticity, so that the groove width of the sliding groove 43 can undergo a small elastic deformation. When the second connecting member 42 is installed at the required position in the first connecting member 41, an elastic buckle / elastic snap ring is used to clamp on the outer wall of the first connecting member 41 to achieve axial limit of the second connecting member 42. When adjustment is needed, the elastic buckle / elastic snap ring is disassembled, and the position of the sliding protrusion 44 of the second connecting member 42 in the axial direction is adjusted, and then the elastic buckle / elastic snap ring can be reinstalled.

[0059] Such as Figure 1 and Figure 2As shown in the figure, the integrated wind turbine foundation further includes a floating box 5 and a pump body. The floating box 5 is installed at the bottom of the aquaculture cage 1 along the height direction. The floating box 5 includes a ballast tank opened inside, an inlet and an outlet communicated with the ballast tank. The inside of the ballast tank is used for storing and discharging ballast water. An inlet valve is installed at the inlet, the outlet is located below the inlet, and a drain valve is installed at the outlet. The pump body is fixedly installed on the floating box 5. The pump body is used to control the ballast water to enter the ballast tank, and the pump body is used to control the ballast water in the ballast tank to be discharged outside the ballast tank.

[0060] With the technical solution of this embodiment, by respectively providing an inlet valve and an outlet valve at the inlet and outlet of the ballast tank opened inside the floating box 5, and adding a pump body, it is convenient to control the amount of ballast water entering the ballast tank, and then realize the flexible adjustment of the draft depth of the whole integrated wind turbine foundation. At the same time, through the setting of the floating box 5, the additional mass and additional moment of inertia of the whole integrated wind turbine foundation can be increased, and the damping of the overall structure can be increased. In addition, due to the high height of the wind turbine assembly, at a certain wind speed, the wind heeling moment is large, which is easy to cause a large pitching phenomenon. By adding the floating box 5, the overall structure is formed into a semi-submersible - semi-columnar structure, which improves the anti-pitching and anti-rolling ability of the single-column wind turbine, and improves the overall viscous damping, improves the motion performance of the whole in terms of pitching automaticity, and adjusts its resonance period.

[0061] It can be explained that a control terminal can be added, which is communicatively connected to the inlet valve and the outlet valve, so as to facilitate timely adjustment of the opening degree of each valve, and then timely adjust the center of gravity of the whole integrated wind turbine foundation, so as to timely adjust the draft depth of the whole integrated wind turbine foundation.

[0062] During the use process, during normal operation, the whole aquaculture cage 1 is located below the water surface, and only the photovoltaic support layer is above the water surface. When towing operation and fish harvesting operation are carried out, it is necessary to empty the ballast water in the ballast tank and raise the whole aquaculture cage 1 to the required height.

[0063] It can be explained that in this application, the installation position of the pump body is not specifically limited. It only needs to be able to flexibly adjust the amount of ballast water in the ballast tank.

[0064] As one of the embodiments, the pump body is fixed close to the ballast tank. With this setting, the length of the pipeline for the flow of ballast water can be reduced, ensuring that the ballast water can be efficiently injected and discharged, and reducing its energy loss.

[0065] Furthermore, a control device, such as a transfer valve box, is added to the flow path of the ballast water to ensure the normal flow and adjustment of the ballast water.

[0066] Preferably, the type of the pump body is selected as a centrifugal pump.

[0067] Furthermore, the number of pump bodies is not specifically limited, and multiple pump bodies can be provided. For example, they can be divided into two groups, respectively used for the injection and discharge of ballast water.

[0068] As Figure 1 shown, the integrated wind turbine foundation further includes an anchor chain 6. One end of the anchor chain 6 is connected to the other end of the first connecting member 41 and the second connecting member 42 along the axial direction thereof, and the other end of the anchor chain 6 is fixed to the seabed surface 72.

[0069] Using the technical solution of this embodiment, by adding the anchor chain 6, the wind turbine foundation can be fixed on the seabed surface 72, improving the degree of displacement or overturning caused by special sea conditions such as wind, waves, and tides, ensuring the stable operation of the wind turbine under extreme weather conditions. At the same time, the installation of the anchor chain 6 is relatively simple, without the need for complex construction equipment and processes, which helps to reduce the construction cost. In addition, after the wind turbine is decommissioned, it can be recycled and reused in a timely manner, meeting the concept of sustainable development.

[0070] It can be noted that in this embodiment, the number of the anchor chains 6 is not specifically limited. As one implementation, multiple anchor chains 6 are provided, such as two or more. At this time, the multiple anchor chains 6 are arranged at intervals around the circumferential direction of the other of the first connecting member 41 and the second connecting member 42.

[0071] Using the technical solution of this embodiment, by providing multiple anchor chains 6, the load received by the wind turbine foundation can be dispersed to the sea, reducing the stress on a single anchor chain 6, thereby improving the bearing capacity and stability of the overall wind turbine foundation. At the same time, by providing multiple anchor chains 6, the maintenance requirements caused by the overall movement or damage of the integrated wind turbine foundation can be reduced, and the operation cost can be lowered.

[0072] As Figure 1 and Figure 2 shown, the wind turbine structure 3 includes a tower barrel 31, a generator, and a wind wheel 32. One end of the tower barrel 31 along its axis is installed on the top of the aquaculture cage 1, and the other end of the tower barrel 31 along its axis extends in a direction away from the sea level 71. The generator is installed at the other end of the tower barrel 31 along its axis. The hub of the wind wheel 32 is drivingly connected to the rotor of the generator through a transmission shaft, or the hub of the wind wheel 32 is drivingly connected to the rotor of the generator through a transmission shaft and a gear structure.

[0073] Using the technical solution of this embodiment, by installing the tower barrel 31 of the fan structure 3 on the top of the aquaculture cage 1, installing the generator on the tower barrel 31, and then drivingly connecting the wind wheel 32 with the rotor of the generator, the wind energy obtained by the wind wheel 32 can be converted into electric energy after passing through the transmission shaft and the gear structure, providing power supply for the aquaculture cage 1 or other facilities set on the sea, reducing the dependence on the external power grid, and improving the self-sufficiency ability of energy supply; at the same time, it is convenient for the operation and maintenance personnel to centrally manage the fan and the aquaculture cage 1, improving the operation and maintenance efficiency.

[0074] It can be explained that in this application, three blades are provided on the wind wheel 32, and at this time, the three blades can be evenly installed circumferentially along the central axis of the hub.

[0075] As Figures 1 to 3 shown, the aquaculture cage 1 includes a support frame 11, and the support frame 11 encloses to form a cylindrical cage.

[0076] Using the technical solution of this embodiment, by providing the support frame 11 in the form of a cylindrical cage, the cage is more stable in the wind and waves, reducing the shaking and deformation caused by wave impact, and ensuring the long-term stable operation of the cage.

[0077] As Figure 1 and Figure 2 shown, the photovoltaic structure 2 includes solar panels 21, the solar panels 21 are laid on the top of the aquaculture cage 1, there are multiple solar panels 21, and the multiple solar panels 21 are spliced to form a disc structure.

[0078] Using the technical solution of this embodiment, by laying multiple solar panels 21 on the top of the aquaculture cage 1, solar radiation can be received, the light energy can be converted into electric energy, and the overall weight can be increased, which helps to resist the influence of bad weather such as wind and waves.

[0079] It can be explained that in this application, an opening can also be provided on the top of the aquaculture cage 1, and the solar panel 21 is installed at the opening so that the solar panel 21, the side wall of the aquaculture cage 1 and the top wall of the floating box 5 enclose to form an aquaculture chamber. At this time, the first connecting member 41 is fixedly connected to the inner wall of the solar panel 21 close to the aquaculture chamber.

[0080] Of course, in other alternative embodiments, an installation platform can also be provided on the top of the aquaculture cage 1, and at this time, one end of the first connecting member 41 along its axis is connected to the installation platform.

[0081] Using the technical solution of this embodiment, by providing an opening on the top of the cage and installing the solar panel 21 at the opening, there is no need to occupy additional land or sea area resources, and the space on the top of the cage is effectively utilized.

[0082] It can be explained that in the present application, the photovoltaic structure 2 further includes components such as an inverter, a distribution box, and a storage battery. At this time, the inverter converts the direct current generated by the solar panels 21 into alternating current, and through the use of cables, the electric energy generated by each solar panel 21 is collected in the energy storage battery and distributed and protected at the distribution box.

[0083] Of course, components for overvoltage protection, undervoltage protection, short-circuit protection, leakage protection, etc. can also be provided. Since there is no improvement on them and they are still in the conventional manner, no specific details will be described here.

[0084] Obviously, the above embodiments are only examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present utility model creation.
