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 for the development of renewable energy. The process of wind power generation is to convert the kinetic energy of wind into mechanical kinetic energy, and then convert the mechanical kinetic energy into electrical kinetic energy. When generating wind power, the higher the wind speed, the greater the kinetic energy of wind, and the more electrical kinetic energy the wind turbine generator will generate. Therefore, wind power generation devices are generally arranged in areas where the wind speed reaches level 6 or above all year round.

[0003] A wind power generation device generally has a rotor and a plurality of windmill blades, which are radially installed around the axis of the rotor. The wind turbine that blows toward the windmill blades from the direction of the rotor axis is converted into power that causes the rotor to rotate around the axis. In order to optimize the working efficiency of the wind power generation device, the rotor of the wind power generation device should be parallel to the wind direction, and the wind force should match the wind power generation device. However, in the atmospheric environment, the air flow conditions are changeable. Therefore, a wind power generation device often needs to adjust the direction of the rotor and the windmill blades so that the rotor and the windmill blades can be in the appropriate direction.

[0004] At present, most of the existing control methods monitor the wind force and wind direction through anemometers and send signals to the electronic controller inside the wind turbine. The electronic controller sends a signal to the yaw mechanism to correct the direction of the rotor so that the rotor of the windmill faces the direction of the wind. However, in the case where the wind turbine is installed on the sea surface, the wind force at sea is large and the wind direction changes quickly. Moreover, in the same wide-angle azimuth, the wind force in different angles is not the same. The existing anemometer can only determine the maximum wind force in a certain wide-angle azimuth, and cannot further determine the most suitable angle of the wind force in the wide-angle azimuth. However, when the wind force in a certain wind direction in the wide-angle azimuth reaches level 8 or above, it is easy to cause damage to the rotor of the wind turbine, which is not conducive to the operation of the wind turbine. Summary of the invention

[0005] The object of the present invention is to provide a data acquisition device for an offshore wind power system. The wind turbine data acquisition device can collect wind data within a wide-angle azimuth determined by an anemometer and determine the optimal wind angle within the wide-angle azimuth, thereby solving the problem that existing wind power generation devices cannot further determine the optimal wind angle within a wide-angle azimuth.

[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 to drive 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; and 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 direction described in the article is 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, thus preventing 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 understandable that the first direction X adopting the horizontal horizontal direction and the second direction Y adopting the vertical longitudinal direction are merely examples of this embodiment. The first direction X and the second direction Y only need to be intersected, and the two do not need to be perpendicular. Moreover, the directions that the first direction X and the second direction Y can adopt are not limited to the above two. Figure 2 The first direction X may be a vertical longitudinal direction, the second direction Y may be a horizontal transverse direction, or the first direction X and the second direction Y may be any two intersecting directions, so that the first adjustment component 3 and the second adjustment component 4 can cooperate with each other, so that the support cover 2b can 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 on the wind power generation device. The airflow enters the support cover 2b from 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 the status data of the transmission fan 2a. It can be understood that the status data of the transmission fan 2a can generally be reflected by the rotation speed of the transmission fan 2a. By analyzing the rotation speed of the transmission fan 2a, it can be known that the flow rate of the airflow entering the support cover 2b in the current direction of the opening 20b, that is, the wind speed.

[0068] Generally speaking, the data acquisition device 100 will pre-set a preset state data according to the parameter specifications of the transmission fan 2a, the parameter specifications of the opening 20b and the application scenario of the data acquisition device 100. For example, the rotation speed of the transmission fan 2a is pre-set to reach a certain value, and when the rotation speed of the transmission fan 2a reaches this value, the airflow must enter the inside of the support cover 2b in a direction perpendicular to the opening 20b, that is, the airflow blows vertically from the front side of the data acquisition device 100 to the back side of the data acquisition device 100. At this time, it can be determined that the current direction of the opening 20b of the data acquisition device 100 is the optimal wind angle in the wide-angle position of the data acquisition device 100.

[0069] It is understandable that the wind environment is complex and changeable. To collect and obtain the optimal wind angle in the current wide-angle orientation, 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 place of use of the data acquisition device 100, the controller 5 can be integrated into the interior of the data acquisition device 100, or it can be introduced into an external control platform or a cloud control platform in the form of 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 connected to the sensor 2c, the first adjustment component 3 and the second adjustment component 4. Fig.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 state data of the transmission fan 2a does not match the preset state data, the first adjustment component 3 is driven to operate, so that the opening 20b rotates relative to the base 1 in the first direction X, and the state data of the transmission fan 2a is changed;

[0073] S3, when the state data of the transmission fan 2a does not match the preset state data, the second adjustment component 4 is driven to operate, so that the opening 20b rotates relative to the base 1 in the second direction Y, and the state data of the transmission fan 2a is changed;

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

[0075] There is no specific order between step S2 and step S3. It is understandable that no matter whether the first adjustment component 3 or the second adjustment component 4 is actuated, the direction of the opening 20b can be adjusted. Therefore, when the state data of the transmission fan 2a does not match the preset state data, there is no specific order for adjusting the first adjustment component 3 and the second adjustment component 4.

[0076] It is understandable that in step S4, the means of recording the orientation of the opening 20b are various. 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 it with the initial state of the first adjustment component 3 and the second adjustment component 4 to obtain the angle difference generated by the first adjustment component 3 and the second adjustment component 4, so as to determine the current orientation of the opening 20b; or, 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 angle difference fed back by the inclinometer.

[0077] When the state data of the transmission fan 2a matches the preset state data, the current orientation of the opening 20b, that is, the wind blows vertically toward the transmission fan 2a. At this time, the wind data acquired by the data acquisition device 100 is the optimal value of the current wide-angle orientation. The controller 5 can feed back the data of the current orientation of the opening 20b to the yaw mechanism of the wind power generation device, so that the yaw mechanism adjusts the orientation of the rotor of the wind power generation device, so that the orientation of the rotor can match the wind direction of the current wide-angle orientation, and the rotor on the wind power generation device can rotate at the most appropriate 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 member group 2e can be composed of three groups of gears. Correspondingly, the transmission shaft 2d is also provided with an output gear 2f, which can mesh with the gear close to the transmission shaft 2d to achieve transmission. The sensor 2c is connected to the gear farthest from the transmission shaft 2d. According to the transmission ratio of the three gears, the sensor 2c can obtain the status data of the rotating shaft and the transmission fan 2a, that is, the rotation speed of the two.

[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 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 a slot 20d arranged in the axial direction, and the slot 20d penetrates the outer surface of the transmission shaft 2d; it also includes a locking assembly 6, the locking assembly 6 includes a block 6a and a first motor 6b, the first motor 6b is arranged beside the transmission shaft 2d, and the block 6a is connected to the output shaft of the first motor 6b, so that the block 6a can rotate relative to the support cover 2b. As the output shaft of the first motor 6b rotates, the block 6a can be embedded in the slot 20d, so that the transmission shaft 2d stops rotating. Of course, when the output shaft of the first electrode rotates in the opposite direction, the block 6a can be disengaged from the slot 20d, so that the transmission shaft 2d is no longer locked. At this time, the transmission fan 2a is driven by the air entering through the opening 20b and 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 rail member 3d extends from the left side of the base 1 to the right side of the base 1. By utilizing the arc-shaped profile of the guide rail member 3d, the inner arc side of the guide rail member 3d, that is, the front side of the guide rail member 3d, is formed in the rotation path 3a in the first direction X. One end of the base 3c connected to the guide rail member 3d may also be an arc-shaped structure, which fits with the inner arc side of the guide rail member 3d, and the base 3c and the guide rail member 3d are arranged concentrically. In this way, when the base 3c moves along the rotation path 3a, the base 3c and the guide rail member 3d can form a matching mode similar to that of the inner ring and the outer ring of the bearing, and the base 3c is restricted to move on the inner arc side of the guide rail member 3d and will not deviate from the rotation path 3a.

[0084] The curvature of the guide rail member 3d and the extension length of the guide rail member 3d in the first direction X will affect the adjustable range of the collection component 2 in the first direction X. Therefore, the guide rail member 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-in groove 33d.

[0085] A slide groove 30b is provided inside the top seat 3b. Moreover, the top seat 3b is matched and connected with a limit seat 32b outside, and the limit seat 32b is also correspondingly provided with a slide groove 30b and a clamping part 31b. The limit seat 32b is matched and installed on the top seat 3b, so that the slide groove 30b of the limit seat 32b is connected with the slide groove 30b of the top seat 3b, and the clamping part 31b of the limit seat 32b is opposite to the clamping part 31b of the top seat 3b. The outer ring part 31d is connected to the bottom of the slide groove 30b, and the side wall of the slide groove 30b is provided with a clamping part 31b extending toward the inside of the slide groove 30b, and the clamping part 31b enters the clamping groove 33d in the second direction Y, so that the guide rail member 3d can be connected and matched 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 guide rail member 3d needs to adjust the relative angle between it and the top seat 3b, 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 escape.

[0087] refer to Figure 1-9 As an example of this embodiment, the first adjustment component 3 also includes a first transmission block 3e, the first transmission block 3e 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 arranged 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 with 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 driving block 1a and the first transmission block 3e can be matched in a gear transmission manner. As an example of this embodiment, the two sides of the inner wall of the base 1 are rotatably connected with a worm 1c, the outer wall of the base 1 is fixedly installed with a third motor, the output end of the third motor is fixedly connected with the worm 1c, and the two sides of the inner wall of the base 1 are also rotatably connected with a worm wheel 1b, the worm wheel 1b is meshed with the worm 1c, and rotates synchronously with the first driving block 1a. In this way, the power output by the third motor can be transmitted to the first driving block 1a through the worm wheel 1b and the worm 1c, so that the first driving block 1a rotates, drives the first transmission block 3e to rotate, and then causes the base 3c to rotate relative to the base 1.

[0089] Taking into account the application scenario of the present wind collection device, in order to avoid excessive wind resistance of the guide rail member 3d, which causes the present wind collection device to be subjected to excessive stress during use, as an example of this embodiment, the number of guide rail members 3d is two, 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 assembly 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 seat 4a, the connecting seat 4a is connected to the base 3c, and the collection component 2 is rotatably connected in the connecting seat 4a; and, the connecting seat 4a is connected to a second transmission block 4b, the output end of the second transmission block 4b passes through the connecting seat 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 may be a planetary gear mechanism, and the second driving block 4c may be a second motor. The second motor is connected to the input shaft of the planetary gear mechanism through a gear set, and the output shaft of the planetary gear mechanism passes through the connecting seat 4a and is transmission-connected to the collection component 2. The output shaft of the second motor drives the gear set to rotate, and the planetary gear mechanism drives the support cover 2b to rotate through the transmission effect of the planetary gear mechanism, so that the wind receiving direction of the transmission fan 2a in the bowl-shaped support cover 2b is deflected.

[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 connecting planes 400a arranged opposite to each other, the connecting planes 400a are parallel to the second direction Y, and the collecting component 2 is rotatably connected to the connecting planes 400a, so that the collecting component 2 can be clamped inside by the connecting seat 4a, and when the collecting 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 collecting component 2 can rotate more smoothly.

[0093] The connection base 4a also includes a bracket portion 41a connected to the connection portion 40a, the bracket portion 41a is connected to the connection portion 40a in a one-to-one correspondence, and the bracket portion 41a extends toward the base 3c and is connected to the base 3c; and the two bracket portions 41a are connected to each other on one side close to the base 3c, and the two bracket portions 41a are left empty on one side close to the collection component 2 to form a rotation space 410a for the collection component 2 to rotate. The empty design of the bracket portion 41a can reduce the wind resistance generated by the second adjustment component 4, and based on the design of the rotation space 410a, the collection component 2 can be embedded in the connection base 4a, so that the structure of the data acquisition device 100 is compact and the wind resistance is lower.

[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 power generation device (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 power generation device, so that the electronic controller 5 sends a signal to the yaw mechanism, so that the fuselage of the wind power generation device corrects the direction, so that the rotor of the wind turbine faces the direction of the wind force, thereby achieving wide-angle adjustment of the rotor.

[0096] Then, the data acquisition device 100 is activated. The wind blows toward the transmission fan 2a, so that the transmission fan 2a drives the transmission shaft 2d to rotate, forcing the transmission shaft 2d to drive the output gear 2f to mesh with the first transmission member group 2e, and the sensor 2c obtains the rotation speed of the transmission fan 2a. At the same time, the sensor 2c transmits the obtained data to the controller 5, and the controller 5 analyzes the data.

[0097] When the controller 5 determines that the state data of the transmission fan 2a does not match the preset state data, the controller 5 controls the first adjustment component 3 to act. The third motor drives the worm 1c to mesh with the worm wheel 1b, so that the driving wheel meshes with the first transmission block 3e, thereby driving the first transmission block 3e and the connecting seat 4a to rotate, and then the connecting seat 4a drives the collection component 2 to rotate, and the direction of the transmission fan 2a changes immediately, so that the wind direction of the transmission fan 2a also changes accordingly. As the angle of wind force cuts in, the speed of the transmission fan 2a changes accordingly. When the speed of the transmission fan 2a changes to the same as the preset state data, the current direction of the opening 20b is the best wind direction for the current wide-angle position. At this time, the controller 5 can feed back the current direction data of the opening 20b to the yaw mechanism of the wind power generation device, so that the fuselage of the wind power generation device can further fine-tune the direction within the current wide-angle range, so that the rotor on the wind power generation device can 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 receiving 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, so that the wind receiving direction of the transmission fan 2a in the support cover 2b is deflected. 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 best 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 power generation device, so that the fuselage of the wind power generation device can further fine-tune the direction within the current wide-angle range, so that the rotor on the wind power generation device can rotate at the most appropriate speed.

[0099] In summary, the embodiment of the present invention provides a data acquisition device 100 that is configured with a collection component 2, so that air can enter the support cover 2b from the opening 20b of the support cover 2b, driving the transmission fan 2a to rotate, so that 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 collection 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 rotate relative to the base 1 in the first direction X and the second direction Y, so that the opening 20b of the support cover 2b rotates to different directions. As the opening 20b rotates, the direction in which the air enters 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 thus 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 optimal wind angle 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.
