Description

Technical Field

[0001] The present invention relates to the technical field of offshore wind power generation, and in particular to a data acquisition device for an offshore wind power system. Background Art

[0002] Offshore wind power generation is a key area of ​​renewable energy development. Wind power generation converts wind kinetic energy into mechanical energy, and then converts mechanical energy into electrical energy. During wind power generation, the higher the wind speed, the greater the wind kinetic energy, and the more electrical energy the wind turbines generate. Therefore, wind turbines are generally deployed in areas with wind speeds consistently exceeding level 6 year-round.

[0003] A wind turbine typically consists of a rotor and multiple blades arranged radially around the rotor's axis. Wind blowing from the rotor axis onto the blades converts wind power into rotational force, which in turn drives the rotors around the axis. To achieve optimal operating efficiency, the rotors must be parallel to the wind direction, and the wind force must be aligned with the device. However, atmospheric airflow is highly variable. Therefore, wind turbines often require adjustments to the rotors and blades to ensure they are properly oriented.

[0004] Currently, most existing control methods use anemometers to monitor wind speed and direction, sending signals to an electronic controller inside the wind turbine. The electronic controller then sends signals to the yaw mechanism, correcting the rotor's direction so that it faces the incoming wind. However, when a wind turbine is installed on the sea, the wind is strong and changes direction quickly. Furthermore, within the same wide-angle direction, the wind speed varies at different angles. Existing anemometers can only determine the maximum wind speed at a specific wide-angle direction and are unable to further determine the angle within that wide-angle direction where the wind speed is most suitable. However, when the wind speed in a specific wide-angle direction reaches level 8 or higher, it can easily damage the rotor of the wind turbine, hindering its operation. Summary of the Invention

[0056] Example

[0057] like Figure 1-15 As shown, an embodiment of the present invention provides a data acquisition device 100 for an offshore wind power system, comprising a base 1, a collection component 2, a first adjustment component 3 and a second adjustment component 4, wherein:

[0058] The collection component 2 includes a transmission fan 2a, a support cover 2b and a sensor 2c. The transmission fan 2a is rotatably connected to the support cover 2b. The support cover 2b is provided with an opening 20b perpendicular to the rotation axis of the transmission fan 2a, so that external air can enter the support cover 2b through the opening 20b, driving the transmission fan 2a to rotate; the sensor 2c is connected to the transmission fan 2a for obtaining status data of the transmission fan 2a.

[0059] The first adjustment component 3 is disposed on the base 1 and connected to the collection component 2; and the first adjustment component 3 forms a rotation path 3a located in the first direction X. The collection component 2 can move along the rotation path 3a to make the opening 20b rotate relative to the base 1 in the first direction X.

[0060] The second adjustment component 4 is connected to the first adjustment component 3 and can rotate synchronously with the collection component 2 in the first direction X; moreover, the second adjustment component 4 can drive the collection component 2 to rotate in the second direction Y, so that the opening 20b rotates relative to the base 1 in the second direction Y, and the second direction Y intersects with the first direction X.

[0061] It should be noted that the directions described in the article are based on the direction in which the user faces the opening 20b of the support cover 2b, wherein the left and right sides are distinguished by the direction in which the user faces the opening 20b of the support cover 2b, the direction of the opening 20b is defined as the front side, and the side opposite thereto is defined as the rear side, and the upper and lower sides of the data acquisition device 100 when generally working normally are defined to distinguish the up and down.

[0062] The outer contour of the support cover 2b can be bowl-shaped, so that the support cover 2b can wrap the left side, right side, back side, top side and bottom side of the transmission fan 2a, leaving only the front side with an opening 20b for airflow to enter, so as to prevent wind from other directions from affecting the transmission fan 2a.

[0063] The first adjustment component 3 is used to adjust the angle of the opening 20b in the first direction X. As an example of this embodiment, the first direction X is Figure 1Driven by the first adjusting assembly 3 , the support cover 2 b can rotate relative to the base 1 in a first direction X, that is, swing left and right relative to the base 1 .

[0064] The second adjustment component 4 is used to adjust the angle of the opening 20b in the second direction Y. As an example of this embodiment, the second direction Y is Figure 1 Driven by the second adjusting assembly 4 , the support cover 2 b can rotate relative to the base 1 in the second direction Y, that is, swing up and down relative to the base 1 .

[0065] Based on the adjustment function of the first adjustment component 3 and the second adjustment component 4, the opening 20b can swing left and right and up and down relative to the base 1, so that the direction of the opening 20b can be changed to adapt to the wind direction of the scene where the wind collection device is located.

[0066] It is understood that the horizontal orientation of the first direction X and the vertical orientation of the second direction Y are merely examples of this embodiment. The first direction X and the second direction Y only need to intersect and do not need to be perpendicular to each other. Furthermore, the directions that the first direction X and the second direction Y can adopt are not limited to the two aforementioned directions. Figure 2 The first direction X may be a vertical longitudinal direction, and the second direction Y may be a horizontal transverse direction. Alternatively, the first direction X and the second direction Y may be any two intersecting directions. The first adjusting component 3 and the second adjusting component 4 may cooperate with each other to enable the support cover 2b to swing left and right and up and down relative to the base 1.

[0067] When the data acquisition device 100 is in use, the base 1 is fixed to the wind turbine. Airflow enters the support cover 2b through the opening 20b, driving the transmission fan 2a to rotate relative to the support cover 2b. At this time, the sensor 2c connected to the transmission fan 2a can obtain status data of the transmission fan 2a. It is understood that the status data of the transmission fan 2a can generally be reflected by the rotational speed of the transmission fan 2a. By analyzing the rotational speed of the transmission fan 2a, the flow rate of the airflow entering the support cover 2b in the current orientation of the opening 20b, i.e., the wind speed, can be determined.

[0068] Generally speaking, the data acquisition device 100 pre-sets a preset state based on the specifications of the transmission fan 2a, the specifications of the opening 20b, and the application scenario of the data acquisition device 100. For example, the transmission fan 2a's rotational speed is pre-set to a certain value. Furthermore, when the transmission fan 2a's rotational speed reaches this value, the airflow must enter the interior of the support cover 2b perpendicularly to the opening 20b, that is, the airflow blows vertically from the front of the data acquisition device 100 to the back of the data acquisition device 100. At this point, it can be determined that the current orientation of the opening 20b of the data acquisition device 100 is the optimal wind angle within the wide-angle position of the data acquisition device 100.

[0069] It is understandable that wind conditions are complex and changeable. To collect and obtain the optimal wind angle within the current wide-angle azimuth, the first adjustment component 3 and the second adjustment component 4 need to adjust the orientation of the opening 20b. Therefore, the data acquisition device 100 needs to be configured with a controller 5 or connected to an external controller. Depending on the location of use of the data acquisition device 100, the controller 5 can be integrated into the data acquisition device 100 or introduced into an external control platform or a cloud-based control platform via a communication connection.

[0070] As an example of this embodiment, the data acquisition device 100 is configured with a controller 5, which is disposed in the base 1 and is connected to the sensor 2c, the first adjustment component 3 and the second adjustment component 4. Figure 15 , the controller 5 is configured to perform the following steps:

[0071] S1, obtaining preset status data and status data of the transmission fan 2a;

[0072] S2. When the status data of the transmission fan 2a does not match the preset status data, the first adjustment component 3 is actuated to rotate the opening 20b relative to the base 1 in the first direction X, thereby changing the status data of the transmission fan 2a.

[0073] S3. When the status data of the transmission fan 2a does not match the preset status data, the second adjustment component 4 is actuated to rotate the opening 20b in the second direction Y relative to the base 1, thereby changing the status data of the transmission fan 2a.

[0074] S4. When the status data of the transmission fan 2a matches the preset status data, record the data of the current orientation of the opening 20b.

[0075] There is no specific order between steps S2 and S3. It is understood that whether the first adjustment component 3 or the second adjustment component 4 is actuated, the orientation of the opening 20b can be adjusted. Therefore, if the status data of the transmission fan 2a does not match the preset status data, there is no specific order in which the first adjustment component 3 and the second adjustment component 4 are adjusted.

[0076] It is understood that in step S4, recording the orientation of the opening 20b can be achieved through various means. For example, the data acquisition device 100 can record the current state of the first adjustment component 3 and the second adjustment component 4, and compare this with the initial state of the first adjustment component 3 and the second adjustment component 4 to obtain the angular difference generated by the first adjustment component 3 and the second adjustment component 4, thereby determining the current orientation of the opening 20b. Alternatively, the data acquisition device 100 can configure an inclinometer at the acquisition component 2 and determine the current orientation of the opening 20b based on the angular difference reported by the inclinometer.

[0077] If the status data of the transmission fan 2a matches the preset status data, the current orientation of the opening 20b indicates that the wind is blowing perpendicularly toward the transmission fan 2a. At this point, the wind data acquired by the data acquisition device 100 represents the optimal value for the current wide-angle orientation. The controller 5 can feed the current orientation data of the opening 20b back to the yaw mechanism of the wind turbine, causing the yaw mechanism to adjust the orientation of the wind turbine's rotors. This ensures that the rotor orientation matches the current wide-angle wind direction, allowing the rotors of the wind turbine to rotate at the optimal speed.

[0078] It is understandable that there are various ways to realize the rotation of the transmission fan 2a relative to the support cover 2b. Figure 13-14 As an example of this embodiment, the support cover 2b is rotatably connected to the transmission shaft 2d, and the transmission fan 2a is connected to the transmission shaft 2d to rotate relative to the support cover 2b; and the support cover 2b is connected to a first transmission member group 2e that can rotate relative to the support cover 2b, the input end of the first transmission member group 2e is connected to the transmission shaft 2d, and the output end of the first transmission member group 2e is connected to the sensor 2c.

[0079] The first transmission assembly 2e can be composed of three sets of gears. Correspondingly, an output gear 2f is also provided on the transmission shaft 2d. The output gear 2f meshes with a gear closer to the transmission shaft 2d to achieve transmission. A sensor 2c is connected to the gear farthest from the transmission shaft 2d. Based on the transmission ratios of the three gears, the sensor 2c can determine the status of the rotating shaft and the transmission fan 2a, namely, their rotational speeds.

[0080] Of course, the first transmission component group 2e can also adopt other transmission methods, such as using other numbers of gears for cooperation, or using transmission methods such as worm gear 1b and worm 1c to transmit the status data of the transmission shaft 2d and the transmission fan 2a to the sensor 2c, which will not be repeated here.

[0081] When the wind collection device does not need to be started, or when the wind collection device needs to obtain the optimal wind angle at the current wide-angle position, the current position of the opening 20b needs to be locked, and the first adjustment component 3 and the second adjustment component 4 do not need to be operated, so the transmission fan 2a can stop rotating, so that the sensor 2c stops obtaining the status data of the sensor 2c. As an example of this embodiment, refer to Figure 13-14 The transmission shaft 2d is provided with an axially arranged slot 20d extending through the outer surface of the transmission shaft 2d. The locking assembly 6 also includes a block 6a and a first motor 6b. The first motor 6b is positioned adjacent to the transmission shaft 2d. The block 6a is connected to the output shaft of the first motor 6b, allowing the block 6a to rotate relative to the support cover 2b. As the output shaft of the first motor 6b rotates, the block 6a engages within the slot 20d, stopping the transmission shaft 2d from rotating. However, if the output shaft of the first motor rotates in the opposite direction, the block 6a can disengage from the slot 20d, unlocking the transmission shaft 2d. At this point, the transmission fan 2a, driven by air entering through the opening 20b, can rotate relative to the support cover 2b.

[0082] The first adjustment component 3 is used to drive the support cover 2b to rotate relative to the base 1 in the first direction X. Figure 1-9 As an example of this embodiment, the first adjustment component 3 includes a top seat 3b and a base 3c, wherein the top seat 3b is connected to the front side of the base 1, and a guide rail member 3d extending toward the collection component 2 is provided on the top seat 3b, the outer contour of the guide rail member 3d is arc-shaped, and the inner arc side of the guide rail member 3d faces the collection component 2, and the rotation path 3a is formed on the inner arc side of the guide rail member 3d; one end of the base 3c is movably connected to the inner arc side of the guide rail member 3d and moves along the rotation path 3a, and the other end of the base 3c is connected to the collection component 2.

[0083] In the first direction X, the guide member 3d extends from the left side of the base 1 to the right side of the base 1. Due to the curved profile of the guide member 3d, the inner curved side of the guide member 3d, i.e., the front side of the guide member 3d, forms a rotation path 3a in the first direction X. The end of the base 3c connected to the guide member 3d can also have a curved structure, which fits with the inner curved side of the guide member 3d, and ensures that the base 3c and the guide member 3d are arranged concentrically. In this way, when the base 3c moves along the rotation path 3a, the base 3c and the guide member 3d can form a fit similar to the inner and outer rings of a bearing. The base 3c is restricted to the inner curved side of the guide member 3d and does not deviate from the rotation path 3a.

[0084] The curvature of the guide rail 3d and the extension length of the guide rail 3d in the first direction X will affect the adjustable range of the collection assembly 2 in the first direction X. Therefore, the guide rail 3d may need to be disassembled and replaced to adapt to different application scenarios of the wind collection device. Figure 8-9As an example of this embodiment, the guide rail member 3d includes an inner ring portion 30d, an outer ring portion 31d and a support portion 32d connected between the inner ring portion 30d and the outer ring portion 31d. The inner ring portion 30d and the outer ring portion 31d are arc-shaped structures, and the connecting portion 40a is recessed in the inner ring portion 30d and the outer ring portion 31d in the second direction Y to form a snap-fit ​​groove 33d.

[0085] A chute 30b is provided within the top seat 3b. Furthermore, the top seat 3b is externally coupled to a limit seat 32b, which is also provided with a chute 30b and a snap-on portion 31b. The limit seat 32b is mounted on the top seat 3b, so that the chute 30b of the limit seat 32b communicates with the chute 30b of the top seat 3b, and the snap-on portion 31b of the limit seat 32b faces the snap-on portion 31b of the top seat 3b. The outer ring portion 31d is connected to the bottom of the chute 30b, and the sidewall of the chute 30b is provided with a snap-on portion 31b extending toward the interior of the chute 30b. The snap-on portion 31b enters the snap-on groove 33d in the second direction Y, enabling the guide rail member 3d to connect and cooperate with the top seat 3b.

[0086] Optionally, the upper side of the guide rail member 3d and the lower side of the guide rail member 3d are connected and fixed to the top seat 3b by bolts. When the relative angle between the guide rail member 3d and the top seat 3b needs to be adjusted, or the guide rail member 3d needs to be disassembled and replaced, the bolts can be loosened to move the guide rail member 3d from the slide groove 30b or remove it.

[0087] refer to Figure 1-9 As an example of this embodiment, the first adjustment component 3 also includes a first transmission block 3e, which is connected to the base 3c, and the outer contour of the first transmission block 3e is arc-shaped, and the first transmission block 3e is arranged along the rotation path 3a; a first driving block 1a is provided in the base 1, and the first driving block 1a is arranged on the outer arc side of the first transmission block 3e and is transmission-connected to the first transmission block 3e to drive the first transmission block 3e to drive the base 3c to move along the rotation path 3a.

[0088] The first drive block 1a and the first transmission block 3e can be coupled using a gear transmission. As an example of this embodiment, a worm 1c is rotatably connected to both sides of the inner wall of the base 1, and a third motor is fixedly mounted on the outer wall of the base 1. The output end of the third motor is fixedly connected to the worm 1c. A worm wheel 1b is also rotatably connected to both sides of the inner wall of the base 1. The worm wheel 1b engages with the worm 1c and rotates synchronously with the first drive block 1a. In this way, the power output by the third motor can be transmitted to the first drive block 1a through the worm wheel 1b and worm 1c, causing the first drive block 1a to rotate, driving the first transmission block 3e to rotate, and then causing the base 3c to rotate relative to the base 1.

[0089] Taking into account the application scenario of the present wind harvesting device, in order to avoid excessive wind resistance of the guide rail member 3d, which causes the present wind harvesting device to be subjected to excessive stress during use, as an example of this embodiment, there are two guide rail members 3d, and the two guide rail members 3d are arranged parallel to each other and spaced apart; the first transmission block 3e is arranged between the two guide rail members 3d and connected to one of the guide rail members 3d, and the first transmission block 3e protrudes from the outer arc side of the guide rail member 3d and extends into the interior of the base 1, so as to cooperate with the first drive block 1a to achieve transmission.

[0090] The second adjustment component 4 is used to drive the support cover 2b to rotate relative to the base 1 in the second direction Y. Figure 10-11 As an example of this embodiment, the second adjustment component 4 includes a connecting base 4a, which is connected to the base 3c, and the collection component 2 is rotatably connected to the connecting base 4a; and a second transmission block 4b is connected to the connecting base 4a, and the output end of the second transmission block 4b passes through the connecting base 4a along the first direction X and is transmission-connected to the collection component 2; and the second transmission block 4b is connected to a second driving block 4c, and the second driving block 4c drives the second transmission block 4b to rotate around its own axis and drives the collection component 2 to rotate in the second direction Y.

[0091] The second transmission block 4b can be a planetary gear mechanism, and the second drive block 4c can be a second motor. The second motor is connected to the input shaft of the planetary gear mechanism via a gear set. The output shaft of the planetary gear mechanism passes through the connecting seat 4a and is in transmission connection with the collection assembly 2. The output shaft of the second motor drives the gear set, which, through the transmission action of the planetary gear mechanism, drives the support cover 2b to rotate, thereby deflecting the wind direction of the transmission fan 2a inside the bowl-shaped support cover 2b.

[0092] refer to Figure 10-11 As an example of this embodiment, the connecting seat 4a includes at least two connecting parts 40a, the two connecting parts 40a are arranged opposite to each other, and the two connecting parts 40a have oppositely arranged connecting planes 400a, the connecting planes 400a are parallel to the second direction Y, and the collection component 2 is rotatably connected to the connecting planes 400a. In this way, the collection component 2 can be clamped inside by the connecting seat 4a, and when the collection component 2 is driven by the second driving block 4c to rotate in the second direction Y, under the constraint of the connecting planes 400a, the collection component 2 can rotate relatively smoothly.

[0093] The connecting base 4a also includes a bracket portion 41a connected to the connecting portion 40a. The bracket portions 41a are connected to the connecting portion 40a in a one-to-one manner and extend toward and connect to the base 3c. Furthermore, the two bracket portions 41a are connected to each other on the side near the base 3c, and the sides of the two bracket portions 41a near the collection assembly 2 are left open to form a rotation space 410a for the collection assembly 2 to rotate. The hollow design of the bracket portions 41a can reduce the wind resistance generated by the second adjustment assembly 4. Based on the design of the rotation space 410a, the collection assembly 2 can be embedded in the connecting base 4a, making the data acquisition device 100 compact and reducing wind resistance.

[0094] Based on the above example, the working process of the data acquisition device 100 of this embodiment is as follows:

[0095] The data acquisition device 100 is installed on the top of an offshore wind turbine. When the external wind direction or wind force changes, the anemometer will send a signal to the electronic controller 5 inside the wind turbine, causing the electronic controller 5 to send a signal to the yaw mechanism, so that the fuselage of the wind turbine corrects the direction and the rotor of the wind turbine faces the direction of the wind, thereby adjusting the wide-angle azimuth of the rotor.

[0096] Subsequently, data acquisition device 100 is activated. Wind blows toward transmission fan 2a, causing it to rotate transmission shaft 2d. This forces output gear 2f to engage with first transmission member assembly 2e. Sensor 2c then acquires the rotational speed of transmission fan 2a. Simultaneously, sensor 2c transmits the acquired data to controller 5, which analyzes the data.

[0097] When the controller 5 determines that the status data of the transmission fan 2a does not match the preset status data, the controller 5 controls the first adjustment assembly 3 to operate. The third motor drives the worm 1c to mesh with the worm gear 1b, causing the driving wheel to mesh with the first transmission block 3e, thereby driving the first transmission block 3e to rotate with the connecting seat 4a. This, in turn, causes the connecting seat 4a to rotate the collection assembly 2, causing the orientation of the transmission fan 2a to change. As the angle of wind penetration changes, the speed of the transmission fan 2a changes accordingly. When the speed of the transmission fan 2a changes to the same as the preset status data, the current orientation of the opening 20b is the optimal wind direction for the current wide-angle azimuth. At this point, the controller 5 can feed the current orientation data of the opening 20b back to the yaw mechanism of the wind turbine, allowing the wind turbine body to further fine-tune its direction within the current wide-angle range, allowing the rotors on the wind turbine to rotate at the most appropriate speed.

[0098] When the third motor drives the connecting seat 4a to rotate and the rotation speed of the transmission fan 2a cannot match the preset state data (that is, the wind direction is not perpendicular to the wind direction of the transmission fan 2a), at this time, the second motor drives the gear set to rotate, and through the transmission action of the planetary gear mechanism, the planetary gear mechanism drives the support cover 2b to rotate, thereby deflecting the wind direction of the transmission fan 2a in the support cover 2b. The purpose of adjustment is the same as that of the first adjustment component 3. When the rotation speed of the transmission fan 2a changes to the same as the preset state data, the current direction of the opening 20b is the optimal wind direction for the current wide-angle orientation. At this time, the controller 5 can feed back the current direction data of the opening 20b to the yaw mechanism of the wind turbine, so that the fuselage of the wind turbine can further fine-tune the direction within the current wide-angle range, so that the rotor on the wind turbine can rotate at the most appropriate speed.

[0099] In summary, an embodiment of the present invention provides a data acquisition device 100 that is configured with a collection component 2. Air can enter the support cover 2b from the opening 20b of the support cover 2b, driving the transmission fan 2a to rotate. In this way, the sensor 2c connected to the transmission fan 2a can obtain the status data of the transmission fan 2a. Through the status data of the transmission fan 2a, the wind force data of the current direction of the acquisition device can be known. Based on the cooperation of the first adjustment component 3 and the second adjustment component 4, the opening 20b of the support cover 2b can be rotated in the first direction X and the second direction Y relative to the base 1, so that the opening 20b of the support cover 2b rotates to different directions. As the opening 20b rotates, the direction of air entering the support cover 2b through the opening 20b will change, which will cause the rotation state of the transmission fan 2a to change, and then cause the state data of the transmission fan 2a obtained by the sensor 2c to change, so that the wind turbine data acquisition device can collect the wind angle within the current wide-angle orientation of the wind turbine, determine the optimal wind angle within the current wide-angle orientation, and enable the wind turbine to further adjust the direction of the rotor within the current wide-angle orientation based on the data collected by the data acquisition device 100.

[0100] Moreover, the data acquisition device 100 of the present application is configured with a controller 5 and uses the controller 5 to obtain preset status data. When the first adjustment component 3 and the second adjustment component 4 drive the support cover 2b to rotate relative to the base 1, the angle of the opening 20b relative to the base 1 will cause the status data of the transmission fan 2a to change. Based on the real-time matching of the preset status data with the status data of the transmission fan 2a, the position where the status data of the transmission fan 2a matches the preset status data is determined, and then the angle of the optimal wind force in the current wide-angle orientation is determined.

[0101] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
