[0059] The present application provides a multi-rotor vertical axis type wind and fish integrated device, please refer to Figure 1 The multi-rotor vertical axis type wind and fish integrated device comprises:

[0060] The culture net cage 1 is used to be moored on the seabed by the anchor chain 2;

[0061] The first rotor 3 is connected with the culture net cage 1, the first rotor 3 is located above the culture net cage 1, and the axis of the first rotor 3 is vertically arranged;

[0062] The first power generation device 4 is connected to the first rotor 3;

[0063] The at least three first blades 5 are arranged on the first rotor 3 in a circumferential direction of the first rotor 3;

[0064] The second rotor 6 is rotatably connected to the first rotor 3, the axis of the second rotor 6 is spaced apart from the axis of the first rotor 3, and the axis of the second rotor 6 is parallel to the axis of the first rotor 3;

[0065] The at least two second blades 7 are arranged on the second rotor 6 in a circumferential direction of the second rotor 6;

[0066] The second blades 7 are used to drive the second rotor 6 to rotate in the first direction under the action of wind, and the first blades 5 are used to drive the first rotor 3 to rotate in the first direction under the action of wind, so as to drive the first power generation device 4 to generate electricity.

[0067] In the embodiment, the culture net cage 1 can be a large deep-sea fishery culture net cage, which can fix the culture net through a truss structure, so that the culture net can enclose a containing space for breeding fish. The culture net cage 1 can float on the sea surface by virtue of its own buoyancy, and is moored to the seabed by the anchor chain 2 to ensure the positional stability of the culture net cage 1 and avoid large deviation of the culture net cage 1 from the sea current.

[0068] The first rotor 3 can be fixedly connected to the top of the truss structure of the culture net cage 1 by a threaded fastener, welding, buckle connection or the like. The first rotor 3 can include a truss structure rotatably connected to the wind turbine fixed support by a bearing, and the second rotor 6 can include a truss structure rotatably connected to the first rotor 3 by a bearing. The position of the second rotor 6 rotatably connected to the first rotor 3 can be set according to actual needs, and preferably the second rotor 6 is arranged in the inner region of the first rotor 3, for example, the second rotor 6 can be rotatably connected to two connection rods arranged in a vertical direction in the truss structure of the first rotor 3 by two upper and lower bearings, as long as the second blades 7 do not interfere with the first rotor 3 and the first blades 5 during rotation of the second rotor 6. Since the axis of the first rotor 3 and the axis of the second rotor 6 are both arranged perpendicular to the ground and the airflow direction, the device does not need to be wind-aimed when the wind direction changes, thereby reducing the gyroscopic force during wind-aiming operation and improving the power generation efficiency.

[0069] In the implementation process, the first rotor 3 and the second rotor 6 can be ensured to rotate in the same direction along the first direction (clockwise or counterclockwise) under the action of the wind by setting the shape and structure of the first blade 5 and the second blade 7 and / or adjusting the attack angle and other parameters. In this way, when the wind flows through the first rotor 3, the first blade 5 is subjected to the action of the wind and drives the first rotor 3 to rotate, converting the kinetic energy of the wind into electrical energy through the first power generation device 4. At the same time, after the wind passes through the first blade 5, it will flow into the internal area of the first rotor 3 (i.e., the area where the second rotor 6 is located). At this time, the wind acts on the second blade 7, which is also subjected to the action of the wind and drives the second rotor 6 to rotate. Since the first rotor 3 and the second rotor 6 rotate in the same direction, and there is an axial distance between the axis of the second rotor 6 and the axis of the first rotor 3, the driving force generated by the rotation of the second rotor 6 will act on the first rotor 3. In this way, a torque is generated on the first rotor 3, promoting the rotation of the first rotor 3, i.e., accelerating the rotation of the first rotor 3, thereby improving the power generation efficiency of the first power generation device 4, i.e., improving the utilization rate of wind energy by the multi-rotor vertical-axis wind-fish hybrid device.

[0070] As can be seen, the present embodiment combines multiple rotor systems to form a multi-rotor vertical-axis wind turbine module that rotates around the outer rotor axis in combination with the self-rotation of the internal rotors, and sets the multi-rotor vertical-axis wind turbine module above the net cage 1 to form a multi-rotor vertical-axis wind-fish hybrid device. The multi-rotor vertical-axis wind turbine group has good stability and motion performance, and at the same time, the multi-rotor vertical-axis wind turbine group does not need to be frequently adjusted according to the change of wind direction, can adapt to complex and variable marine environment, and will not have a huge difference in cost due to factors such as water depth of the sea area. Based on the multi-rotor vertical-axis wind-fish hybrid device, the space utilization rate can be improved and the cost can be reduced under the premise of fully utilizing wind energy resources and fishery resources.

[0071] Optionally, referring to Figure 1 and Figure 2 , the net cage 1 includes a net cage body 11, a net cover 12, and a floating body 13; the net cover 12 covers the net cage body 11;

[0072] The net cage body 11 includes a first surrounding frame 111, a second surrounding frame 112, a first support column 113, a second support column 114, and a support beam 115; the upper end of the first support column 113 is connected to the first surrounding frame 111, the lower end of the first support column 113 is connected to the second surrounding frame 112, the second support column 114 is located at the center of the first surrounding frame 111 and the second surrounding frame 112, the first end of the support beam 115 is connected to the second support column 114, and the second end of the support beam 115 is connected to the first surrounding frame 111 and / or the second surrounding frame 112; the first rotor 3 is installed at the upper end of the second support column 114;

[0073] The float 13 is set around the first frame 111.

[0074] Specifically, with Figure 2 Taking the example shown, the first frame 111 and the second frame 112 can be rectangular. The number of first support columns 113 can be eight, with four columns connecting the four corners of the first frame 111 and the four corners of the second frame 112, and the other four columns connecting the center points of the four sides of the first frame 111 and the four sides of the second frame 112. Second support columns 114 are vertically positioned at the centers of the first frame 111 and the second frame 112. The number of support beams 115 can be eight, with four beams connecting the center points of the four sides of the first frame 111 and the second support column 114, and the other four beams connecting the center points of the four sides of the second frame 112 and the second support column 114. Based on this structural configuration, the cage body 11 can form a stable hexahedral truss structure. The netting 12 covers the five faces of this hexahedral truss structure, excluding the top face, to create a space for raising fish. The float 13 can be an inflatable airbag or made of buoyancy materials such as foamed plastic. The float 13 is arranged around the first frame 111. Since the first frame 111 is located above the net cage body 11, the buoyancy of the float 13 can help the net cage body 11 float on the sea surface while ensuring that the net cage part below the first frame 111 is below the sea surface, so as to obtain sufficient aquaculture space.

[0075] Preferably, in each closed-loop frame structure formed by the first frame 111, the second frame 112 and the first support column 113, a support rod 116 can be provided accordingly. The support rods 116 can be arranged in a cross pattern to form a reinforcement effect and improve the overall structural stability of the aquaculture cage 1.

[0076] Optionally, refer to Figures 1 to 3 The number of second rotors 6 is at least three, and the at least three second rotors 6 are arranged at circumferential intervals along the first rotor 3.

[0077] When multiple second rotors 6 are configured, the empty internal area in the truss structure of the first rotor 3 can be fully utilized, and the rotation of the first rotor 3 can be further accelerated by the driving force generated when multiple second rotors 6 rotate, thereby further improving the utilization rate of wind energy and power generation efficiency.

[0078] Optionally, the first blade 5 is a lift-type blade or a drag-type blade.

[0079] Optionally, the second blade 7 is a lift-type blade or a drag-type blade.

[0080] When the blades are lift-type blades, the corresponding rotor constitutes a Darrieus-type lift-type wind turbine. At this time, the cross section of the blade can have an airfoil shape, and the airfoil section of the blade can generate lift under the action of wind to drive the corresponding rotor to rotate. The rotational speed of the lift-type wind turbine can be several times the current wind speed, and the power generation efficiency is relatively high. However, in the low-speed rotating stage, the attack angle of the blade is difficult to maintain in an appropriate range to generate sufficient lift, so it is not easy to start by itself.

[0081] When the blades are lift-type blades, the corresponding rotor constitutes a Darrieus-type lift-type wind turbine. At this time, the cross section of the blade can have an airfoil shape, and the airfoil section of the blade can generate lift under the action of wind to drive the corresponding rotor to rotate. The rotational speed of the lift-type wind turbine can be several times the current wind speed, and the power generation efficiency is relatively high. However, in the low-speed rotating stage, the attack angle of the blade is difficult to maintain in an appropriate range to generate sufficient lift, so it is not easy to start by itself.

[0082] In the embodiment, the first blades 5 and the second blades 7 can be set as lift-type blades or drag-type blades according to actual needs, thereby generating four combinations. Further, when the second rotor 6 is provided as at least three, the second blades 7 on different second rotors 6 can also be set as lift-type blades or drag-type blades, which is not limited here. Preferably, the multi-rotor vertical-axis wind turbine hybrid device can be provided with both lift-type blades and drag-type blades, so that the advantages of the two types of wind turbines can be utilized to improve the starting property and the power generation efficiency.

[0083] Optionally, referring to Figures 1 to 3 , the first rotor 3 comprises a first rotating shaft 31, a first connecting rod 32 and a second connecting rod 33, and each second rotor 6 comprises a second rotating shaft 61 and at least two third connecting rods 62; wherein:

[0085] The number of the first connecting rods 32 is at least three, and one end of each of the at least three first connecting rods 32 is arranged on the first rotating shaft 31 in a circumferential direction of the first rotating shaft 31, and the other end of each of the at least three first connecting rods 32 is connected to the first blade 5 in one-to-one correspondence;

[0086] The number of the second connecting rods 33 is equal to the number of the first blades 5, one end of each second connecting rod 33 is connected to any first blade 5, and the other end of each second connecting rod 33 is connected to another first blade 5 adjacent to the first blade 5;

[0089] After studying the existing vertical axis wind turbine, it is found that the rotor diameter of the existing vertical axis wind turbine is large, and no other structural member is arranged in the space region of the blade rotation except the support for fixing the rotor, so that the space and wind energy resources in the region are wasted.

[0090] Based on the above finding, the embodiment proposes a specific rotor structure. Illustratively, the first rotating shaft 31 can be rotatably connected to the fan fixing support through a bearing, and the lower end of the first rotating shaft 31 can be connected to the rotor part of the first power generation device 4.

[0091] The second connecting rod 33 is used to directly connect adjacent first blades 5, and a plurality of second connecting rods 33 jointly form a closed polygonal structure, which can further improve the structural strength and stability of the first rotor 3, and at the same time, the idle area between each first blade 5 can provide a mounting position for the second rotor 6, so that a plurality of second rotors 6 can respectively fill the space between each group of adjacent first blades 5, thereby reducing the space waste in the first rotor 3, improving the utilization rate of wind energy resources, and improving the space utilization rate.

[0092] The second rotating shaft 61 can be rotatably connected to the second connecting rod 33 through a bearing. Each third connecting rod 62 can include Figure 3 at least one transverse rod, and the transverse rod in each third connecting rod 62 is connected to the corresponding second blade 7 of the third connecting rod 62.

[0094] The first rod body 331, the second rod body 332 and the third rod body 333 are arranged along the axial direction of the first rotating shaft 31; one end of each first rod body 331, one end of each second rod body 332 and one end of each third rod body 333 are connected to any first vane 5, and the other end of each first rod body 331, the other end of each second rod body 332 and the other end of each third rod body 333 are connected to another adjacent first vane 5;

[0098] In the embodiment, the first rod body 331, the second rod body 332 and the third rod body 333 in each second connecting rod 33 are arranged to divide two rectangular areas above and below between the two adjacent first vanes 5; at this time, each second rotor 6 is actually also divided into two above and below; wherein the upper second rotor 6 is arranged between the first rod body 331 and the second rod body 332 through the bearing connection of the first shaft body 611 and the first rod body 331 and the second rod body 332, and the lower second rotor 6 is arranged between the second rod body 332 and the third rod body 333 through the bearing connection of the second shaft body 612 and the second rod body 332 and the third rod body 333. Through the above arrangement, the structural strength and stability of the first rotor 3 can be further improved by the vertical arrangement of the multiple rod bodies in the second connecting rod 33, while meeting the installation requirements of the second rotor 6.

[0099] Optionally, referring to Figures 1 to 3 The number of the first vanes 5, the number of the first connecting rods 32 and the number of the second connecting rods 33 are all three and are evenly distributed along the circumferential direction of the first rotor 3, and the three second connecting rods 33 form an equilateral triangle.

[0100] Illustratively, when the first blades 5 and the second rotors 6 are uniformly distributed along the circumference of the first rotor 3, the angle between the connecting line between the axis of each second rotating shaft 61 and the axis of the first rotating shaft 31 and the adjacent first connecting rod 32 is equal, so as to improve the balance of the multi-rotor vertical axis wind and fish hybrid device and the uniformity of the wind force acting on the first blades 5 and the second rotors 6, thereby improving the stability of the multi-rotor vertical axis wind and fish hybrid device in operation.

[0101] In addition, when the three second connecting rods 33 form an equilateral triangle as shown in the drawings, the structural strength and stability of the first rotor 3 can be further improved based on the characteristics of the high stability of the triangular structure. Figure 3

[0102] Optionally, referring to Figures 1 to 5 , each second rotating shaft 61 is rotatably connected to the center of the corresponding second connecting rod 33.

[0103] When each second rotor 6 is located at the center position of the corresponding second connecting rod 33, the balance of the multi-rotor vertical axis wind and fish hybrid device can be improved while maximizing the diameter of the second rotor 6; as the diameter of the second rotor 6 increases, the pushing force generated by the second rotor 6 when rotating on the first rotor 3 also increases, thereby further improving the power generation efficiency.

[0104] Among them, as shown in the drawings, the diameter D2 of the second rotor 6 should be set to be smaller than the diameter D3 of the inscribed circle formed by the adjacent two first connecting rods 32 and the virtual circle on the outer diameter of the first rotor 3, so as to avoid collision and interference between the second rotor 6, the second blade 7 and the first rotor 3, the first blade 5 during rotation. Figure 4

[0105] Optionally, referring to Figures 1 to 5 , the diameter of the first rotor 3 is greater than or equal to the height of the first blade 5; wherein the height of the first blade 5 is the maximum distance of the first blade 5 in the axial direction of the first rotor 3.

[0106] Optionally, referring to Figures 1 to 5 , the diameter of the second rotor 6 is greater than or equal to the height of the second blade 7; wherein the height of the second blade 7 is the maximum distance of the second blade 7 in the axial direction of the second rotor 6.

[0107] As shown in the drawings Figure 4 and Figure 5 ​​As shown, by setting the diameter D1 of the first rotor 3 to be greater than or equal to the height L1 of the first blade 5, and setting the diameter D2 of the second rotor 6 to be greater than or equal to the height of the second blade 7, the structural stability of the first rotor 3 and the second rotor 6 can be further improved. When the second rotor 6 comprises the first shaft body 611 and the second shaft body 612 in the above-mentioned embodiments, i.e. the second rotor 6 is divided into two parts, the diameter D2 of the upper second rotor 6 is greater than or equal to the height L2 of the second blade 7 connected thereto, and the diameter D2 of the lower second rotor 6 is greater than or equal to the height L3 of the second blade 7 connected thereto; preferably, L2 is equal to L3.

[0108] Further, in an exemplary embodiment, the multi-rotor vertical axis wind-fish hybrid device further comprises a second power generation device (not shown in the figure) connected to the second rotor 6.

[0109] The second blade 7 is used to drive the second rotor 6 to rotate under the action of wind, so as to drive the second power generation device to generate electricity.

[0110] In the present embodiment, through the rotation of the second rotor 6, not only can the first rotor 3 be driven to rotate by the torque generated by the second rotor 6, but also the second power generation device can be driven to operate at the same time, so as to convert the kinetic energy of wind into electrical energy, thereby further improving the power generation efficiency and the utilization rate of wind energy of the multi-rotor vertical axis wind-fish hybrid device through the joint operation of the first power generation device 4 and the second power generation device. Specifically, when the second rotor 6 comprises the first shaft body 611 and the second shaft body 612 in the above-mentioned embodiments, the second power generation device can also be correspondingly provided as two, and the rotor parts of the two second power generation devices can be respectively connected to the first shaft body 611 and the second shaft body 612.

[0111] Optionally, referring to Figures 1 to 7 , the multi-rotor vertical axis wind-fish hybrid device comprises an auxiliary blade 8; the auxiliary blade 8 is rotatably connected to the first rotor 3 around the vertical axis, and the auxiliary blade 8 is located between the axis of the first rotor 3 and the first blade 5.

[0112] When the auxiliary blade 8 is rotated to a first preset angle, the front end of the auxiliary blade 8 abuts against the front end of the first blade 5, and the auxiliary blade 8 and the first blade 5 form a wind bag structure;

[0113] When the auxiliary blade 8 is rotated to a second preset angle, the front end of the auxiliary blade 8 points to the adjacent second rotor 6, and a flow passage is formed between the auxiliary blade 8 and the first blade 5, and the flow passage is opposite to the second blade 7 on the adjacent second rotor 6.

[0114] Specifically, with the structure of the first rotor 3 as Figure 6 and Figure 7As shown, the arrows represent the wind direction, and the auxiliary blades 8 are rotatably connected to any one or more of the first connecting rods 32, each auxiliary blade 8 corresponding to the first blade 5 on the first connecting rod 32 where it is located. Figure 6 As shown, when the auxiliary blades 8 are rotated to the first preset angle, the front ends of the auxiliary blades 8 abut the front ends of the corresponding first blades 5 to form a V-shaped wind bag structure; when the airflow enters from the opening of the wind bag structure, the wind bag structure can form a better blocking effect on the airflow, forming a drag-type blade structure, allowing the first rotor 3 to obtain a larger torque, so that the first rotor 3 is more easily statically started under the same wind conditions.

[0115] When the first rotor 3 is statically started and reaches a certain speed, as shown, Figure 7 the auxiliary blades 8 can be rotated to the second preset angle, at which time the front ends of the auxiliary blades 8 point to the adjacent second rotor 6 connected to the second connecting rod 33, and the auxiliary blades 8 form a flow passage with the first blades 5. The flow passage is opposite the second blade 7 on the adjacent second rotor 6. Based on the structure at this time, a portion of the airflow reaching the auxiliary blades 8 can be blocked by the auxiliary blades 8, so that this portion of the airflow can flow to the shaft center of the second rotor 6 and the second blade 7 along the side of the auxiliary blades 8 away from the first blades 5, and then the airflow can produce a pushing effect on the second rotor 6, promoting the rotation of the second rotor 6; another portion of the airflow reaching the auxiliary blades 8 flows to the second blade 7 along the tangent under the guidance of the flow passage, so that this portion of the airflow can generate a pressure difference through cooperation with the surface wing profile of the second blade 7, and then generate lift, so that the rotation of the second rotor 6 is also promoted.

[0116] As can be seen, by providing rotatable auxiliary blades 8, the first rotor 3 can be more easily statically started under the same wind conditions, and after the first rotor 3 is statically started, more airflow can be directionally guided to the second rotor 6, so that the second rotor 6 can obtain a higher speed under the same wind conditions, thereby further improving the power generation efficiency of the second power generation device, and further improving the acceleration of the second rotor 6 on the first rotor 3, thereby further improving the power generation efficiency of the first power generation device 4, and further improving the utilization rate of wind energy of the multi-rotor vertical-axis wind turbine hybrid device.

[0117] Alternatively, referring to Figures 1 to 7 , the second rotor 6 is provided with a wind-facing plate 9 located between the shaft center of the second rotor 6 and the second blade 7, and the wind-facing plate 9 is opposite the flow passage.

[0118] Illustratively, the wind-facing plate 9 can be arranged on the third connecting rod 62; by arranging the wind-facing plate 9, the airflow between the axial center of the second rotor 6 and the second blade 7 flowing along the side of the auxiliary blade 8 away from the first blade 5 can be blocked, so that the part of the airflow can be better utilized to push the second rotor 6 to rotate.

[0119] Optionally, referring to Figures 1 to 7 , the multi-rotor vertical axis wind and fish integrated device comprises a driving device (not shown in the figure) and a speed measuring device (not shown in the figure); the driving device is connected with the auxiliary blade 8, and the speed measuring device is electrically connected with the driving device; the speed measuring device is used to obtain the rotating speed of the first rotor 3, and the speed measuring device is used to send a switching signal to the driving device when the rotating speed of the first rotor 3 reaches a preset rotating speed; the driving device is used to control the auxiliary blade 8 to rotate from the first preset angle to the second preset angle when the switching signal is received.

[0120] Specifically, the driving device and the speed measuring device can realize communication through an MCU microcontroller, the preset rotating speed can be pre-stored in a storage module of the MCU microcontroller, and the switching signal can be a high-level signal or a low-level signal for triggering a circuit to perform corresponding operations. Through the cooperation of the driving device and the speed measuring device, the automatic adjustment of the rotating angle of the auxiliary blade 8 can be realized according to the current operating condition, so that the different flow guiding requirements of the static starting stage and the high-speed stage can be met in a more intelligent manner.

[0121] Of course, in actual application process, the rotating angle of the auxiliary blade 8 is not limited to the first preset angle and the second preset angle, and the auxiliary blade 8 can be rotated to other different angles in real time during the operation of the first rotor 3 and the second rotor 6 according to the needs, so as to meet the real-time flow guiding requirements.

[0122] It should be noted that other contents of the multi-rotor vertical axis wind and fish integrated device disclosed in the present application can refer to the prior art, which will not be described here.

[0123] The above is only an optional embodiment of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation made by using the contents of the present application specification and drawings, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
