Description

Technical Field

[0001] The present invention relates to the technical field of generator sets, and specifically to an intelligent start-up generator set for all operating conditions of offshore wind power. Background Technique

[0002] The intelligent start-up generator set for all operating conditions of offshore wind power utilizes wind power generation. It is one of the core devices in the offshore wind power generation system, mainly relying on wind drive to achieve power generation. The sea breeze drives the blades of the wind turbine to rotate, and the rotation of the blades drives the movement of the rotor inside the generator. The rotor makes a cutting magnetic induction line movement in the magnetic field of the stator. According to the law of electromagnetic induction, induced electromotive force and induced current will be generated in the stator winding, thereby converting wind energy into electrical energy and realizing the process of wind power generation. Moreover, the intelligent start-up for all operating conditions emphasizes that this generator can optimize the start-up and operation processes through an intelligent control system under various complex offshore operating conditions to improve power generation efficiency and the reliability and stability of the equipment.

[0003] Currently, during the process of wind power generation by the intelligent start-up generator set for all operating conditions of offshore wind power, the rotation speed of the generator is adjusted in real time according to the wind conditions at sea through the adjustment of the intelligent control system. However, when encountering strong winds, the strong winds will cause a greater radial force on the wind wheel part, which is transmitted to the ball bearing through the rotating shaft, resulting in an increase in the radial load borne by the ball bearing. As a result, the contact stress between the balls and the raceway exceeds the normal level, accelerating the wear of the balls and the raceway, and thus easily leading to the damage of the ball bearing. Most of the existing intelligent start-up generator sets for all operating conditions of offshore wind power do not provide additional protection for the ball bearing.

[0004] Therefore, we propose an intelligent start-up generator set for all operating conditions of offshore wind power to solve the problems raised above. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. When it is necessary to use the intelligent start-up generator set for offshore wind power under all working conditions to generate wind power, in order to provide multiple protections for the ball bearing body, lubricating oil is added to the inside of the ball bearing body through an oil coating sleeve. When the wind detector detects that the external wind force is too strong, by increasing the raised parts on the surfaces of the three second gears, when the wind wheel converts wind power into mechanical energy and transmits it to the surfaces of the three second gears, due to the increase in the raised parts on the surfaces of the second gears, the friction force on the first gear is increased, and thus the rotation speed of the connecting shaft is reduced, solving the problem that most intelligent start-up generator sets for offshore wind power under all working conditions in the prior art are prone to damage of the roller bearings when encountering strong winds.

[0018] 2. When the offshore wind power decreases, move the multiple Y-shaped push blocks out of the outer surfaces between every two corresponding connecting rods respectively. As a result, the two corresponding magnets are no longer limited by the Y-shaped push blocks, so that the two corresponding magnets attract each other and move towards the center position of the convex block respectively. Then, they drive each group of positioning balls to move towards the inside of the convex block respectively, and further make the multiple positioning balls move out of the circular holes in the card slots. Then, the multiple convex blocks can be separated from the three second gears respectively, reducing the protrusions on the surface of the second gear, decreasing the protruded part on the surface of the second gear, reducing the friction of the generator set, and thus improving the power generation efficiency.

[0019] 3. To reduce the wear of the ball bearing body, first, the central control unit sends out an instruction outward. The wind power detection module and the sensitive unit receive the instruction. After being processed and analyzed by the data acquisition module, the data analysis module, and the data processing module, it is transmitted to the remote monitoring and management part to realize the multiple detection and protection of the ball bearing body in the intelligent start-up of the offshore wind power generator under all working conditions.

The energy conversion component 3 includes a nacelle 301. A wind detector 2 is provided on the outer surface of the nacelle 301. The bottom of the nacelle 301 is fixedly connected to the top of the support structure 1. A generator body 302 is provided inside the nacelle 301. A connecting shaft 303 is provided at the input end of the generator body 302. A ball bearing body 304 is provided on the outer surface of the connecting shaft 303. An acceleration sensor 305 is provided on the outer surface of the ball bearing body 304. A sealing tank 306 is provided between the inner walls of the nacelle 301. An intelligent switch control valve 307 is provided on the outer surface of the liquid outlet pipe in the sealing tank 306. One end of the liquid outlet pipe is fixedly communicated with an oil coating sleeve 308. The inner wall of the oil coating sleeve 308 is in contact with the outer surface of the ball bearing body 304. One end of the connecting shaft 303 movably penetrates to the outside of the nacelle 301. A slider 503 is movably sleeved on the outer surface of the connecting shaft 303. The other end of the telescopic rod 501 is fixedly connected to the outer surface of the nacelle 301. The outer surface of the hydraulic rod 502 is fixedly connected to the outer surface of the nacelle 301 by screws. The wind energy capture component 4 includes a fixed ring 401. The outer surface of the fixed ring 401 is fixedly connected to the opposite outer surface of the nacelle 301. An internal gear ring 402 is rotatably connected to the inner wall of the fixed ring 401. A first gear 403 is fixed at one end of the connecting shaft 303. Three second gears 404 are meshed with the outer surface of the first gear 403. The outer surfaces of the three second gears 404 are all meshed with the outer surface of the internal gear ring 402. A switching frame 405 is movably connected between the outer surfaces of the three second gears 404 through an extension shaft. A wind wheel 406 is fixed on the outer surface of the switching frame 405. A plurality of card slots 407 are respectively formed on the outer surfaces of the three second gears 404. The inner walls of the plurality of card slots 407 respectively slide with the outer surfaces of a plurality of bumps 509. An electric push rod 408 is provided on the outer surface of the fixed ring 401 through an auxiliary frame. An extension rod 409 is fixedly installed at one end of the electric push rod 408. An infrared sensor 410 is provided on the inner wall of the extension rod 409.

[0024] In this embodiment, when it is necessary to use the intelligent start-up generator set under all operating conditions of offshore wind power for wind power generation, due to the large variation of offshore wind power, during operation, the wind detector 2 is first started. Among them, the wind detector 2 measures the wind speed by using the rotation of the propeller in the wind. The rotation plane of the propeller is perpendicular to the wind direction. When the wind blows the propeller, the propeller rotates, and its rotation speed is proportional to the wind speed. By detecting the rotation speed of the propeller through the sensor installed on the propeller shaft, the wind speed can be obtained. When the wind detector 2 detects that the current offshore wind power is within the standard range, the electric push rod 408 can be started to shorten it, driving the extension rod 409 to move away from the inside of the internal gear ring 402 to the outside of the fixed ring 401 until it is completely removed, releasing the limit on the internal gear ring 402. The wind wheel 406 will rotate under the action of the external wind power, thus driving the switching frame 405 to rotate, and then driving the three second gears 404 to rotate, so that the internal gear ring 402 and the first gear 403 arranged at the central position rotate, driving the connecting shaft 303 to rotate, and then driving the ball bearing body 304 to rotate. Then, the generator body 302 converts mechanical energy into electrical energy, realizing the conversion of energy. Among them, through the action of the ball bearing body 304, the connecting shaft 303 maintains a stable position and posture during operation, provides reliable support for the connecting shaft 303, ensures that the rotating shaft can rotate stably around its axis, maintains the relative position relationship between the components inside the generator body 302, and ensures the normal operation of the generator body 302. At the same time, the acceleration sensor 305 is started to detect the operating state of the ball bearing body 304. Among them, when the ball bearing body 304 is worn, the worn part will change the intensity and frequency characteristics of this vibration. The sensitive part of the acceleration sensor 305 will sense these vibration accelerations, and compare the extracted signal characteristics with the pre-established normal bearing vibration characteristic library and the bearing vibration characteristic library with known wear degrees and types to track the development process of bearing wear. When it is detected that there is wear inside the ball bearing body 304, the intelligent switch control valve 307 can be opened through the external control system, so that the lubricating oil stored in the sealed tank 306 flows downward under its own gravity to the inside of the oiling sleeve 308. Among them, as Figure 2 shown, since a plurality of oil inlet holes are formed on the outer surface of the ball bearing body 304, the lubricating oil in the oiling sleeve 308 enters the inside of the ball bearing body 304 along the oil inlet holes, realizing the lubrication of the ball bearing body 304, effectively protecting it, and preventing the ball bearing body 304 from being damaged due to the influence of friction force.

[0025] As Figure 1 and Figures 4-11As shown in the figure, an intelligent start-up generator set for all operating conditions of offshore wind power includes a support structure 1. At the top of the support structure 1, an energy conversion component 3 is provided for converting mechanical energy into electrical energy. On the outer surface of the energy conversion component 3, a wind energy capture component 4 is provided for converting wind energy into mechanical energy. On the outer surface of the wind energy capture component 4, a load adjustment component 5 is provided. The load adjustment component 5 includes a telescopic rod 501 and a hydraulic rod 502. A slider 503 is fixedly installed between one ends of the telescopic rod 501 and the hydraulic rod 502. Three mounting rods 504 are fixed to the outer surface of the slider 503. Three mounting rings 505 are movably sleeved on the outer surfaces of the three mounting rods 504. Cylinders 506 are provided near the center of the inner walls of the three mounting rings 505. Moving frames 507 are fixedly installed at one ends of the three cylinders 506. A plurality of Y-shaped push blocks 508 are fixedly installed near the outer edges of the outer surfaces of the three moving frames 507. A plurality of bumps 509 are fixedly connected to the outer surfaces of the three mounting rings 505. Two connecting rods 510 are slidably connected to the inner walls of the plurality of bumps 509. A plurality of springs 512 are provided on the outer surfaces of the other sides of the plurality of connecting rods 510. Positioning balls 513 are provided at one ends of the plurality of springs 512. Magnets 511 are fixed to the outer surfaces of one sides of the plurality of connecting rods 510. The outer surfaces of the plurality of moving frames 507 are slidably connected to the inner walls of the plurality of mounting rings 505 respectively. One ends of the plurality of springs 512 respectively pass through the outside of the plurality of bumps 509 movably. One ends of the plurality of springs 512 are fixedly connected to the outer surfaces of the plurality of connecting rods 510 respectively. The other ends of the plurality of springs 512 are fixedly connected to the outer surfaces of the plurality of positioning balls 513 respectively.

[0026] In this embodiment, when the wind detector 2 detects that the external wind force is too strong, in order to prevent the external strong wind from damaging the ball bearing body 304, when the offshore wind force is too large, the infrared sensor 410 is first started. When the infrared sensor 410 detects that Figure 6 as shown in the figure, the circular groove in the internal gear ring 402 coincides exactly with the circular groove in the fixed ring 401, the electric push rod 408 can be immediately started to extend, driving the extension rod 409 to move into the internal gear ring 402, realizing the positioning of the internal gear ring 402. The positioning of the internal gear ring 402 makes the three second gears 404 stop rotating, and the card slots 407 on the surface of each second gear 404 exactly correspond to the plurality of bumps 509 corresponding to them. At this time, the hydraulic rod 502 can be started to extend, driving the slider 503 to move forward along the outer surface of the connecting shaft 303, so that the plurality of bumps 509 are respectively inserted into the plurality of card slots 407 corresponding to them. Among them, during the process of the plurality of bumps 509 being respectively inserted into the plurality of card slots 407, the plurality of positioning balls 513 are squeezed, driving the plurality of springs 512 to shorten, so that the plurality of positioning balls 513 are respectively inserted into Figure 8In the circular holes inside the shown bump 509, when the hydraulic rod 502 extends to its longest, multiple bumps 509 exactly insert into the deepest part of multiple card slots 407, and at this time, multiple positioning balls 513 exactly move to positions corresponding to the circular holes in multiple card slots 407 as shown in Figure 11 . Multiple positioning balls 513 will respectively insert into the circular holes in the corresponding card slots 407 under the action of the self-elastic force of their corresponding multiple springs 512. Among them, as shown in Figure 8 and Figure 11 , the outer diameter of each row of positioning balls 513 gradually decreases from front to back, and the inner diameter of each circular hole groove also gradually decreases from outside to inside. Therefore, during the movement of the positioning balls 513, it will not cause the positioning balls 513 to insert into the circular hole grooves that do not correspond to them during the movement. When multiple positioning balls 513 are all inserted into the corresponding circular hole grooves, the installation of multiple bumps 509 is realized, so that the protruding parts in each second gear 404 are doubled. Furthermore, when the wind wheel 406 converts wind energy into mechanical energy and transmits it to the surfaces of three second gears 404, due to the increase in the protruding parts on the surfaces of the second gears 404, the friction force on the first gear 403 is increased, thereby reducing the rotation speed of the connecting shaft 303, reducing the wear of the ball bearing body 304, effectively protecting the ball bearing body 304, and solving the problem that most offshore wind power full-condition intelligent start generating sets in the prior art are prone to damage the roller bearings when encountering strong winds.

[0027] As shown in Figure 1 and Figures 7-10 , an offshore wind power full-condition intelligent start generating set includes a support structure 1. At the top of the support structure 1, an energy conversion component 3 for converting mechanical energy into electrical energy is provided. On the outer surface of the energy conversion component 3, a wind energy capture component 4 for converting wind energy into mechanical energy is provided. On the outer surface of the wind energy capture component 4, a load adjustment component 5 is provided. The load adjustment component 5 includes a telescopic rod 501 and a hydraulic rod 502. A slider 503 is fixedly installed between one ends of the telescopic rod 501 and the hydraulic rod 502. Three mounting rods 504 are fixedly installed on the outer surface of the slider 503. Three mounting rings 505 are movably sleeved on the outer surfaces of the three mounting rods 504. Cylinders 506 are provided near the center of the inner walls of the three mounting rings 505. One ends of the three cylinders 506 are fixedly installed with moving frames 507. Multiple Y-shaped push blocks 508 are fixedly installed near the outer edges of the outer surfaces of the three moving frames 507. Multiple bumps 509 are fixedly connected to the outer surfaces of the three mounting rings 505. Two connecting rods 510 are slidably connected to the inner walls of the multiple bumps 509.

[0028] In this embodiment, when the wind detector 2 detects a decrease in the offshore wind force, the extension rod 409 can be inserted into the inner gear ring 402 again, and then the three cylinders 506 are started to shorten, respectively driving the three moving frames 507 to move along the inner walls of the three mounting rings 505 in a direction away from the bump 509, so that the multiple Y-shaped push blocks 508 are respectively moved out of Figure 8 between the outer surfaces of each two corresponding connecting rods 510 as shown. Furthermore, the two corresponding magnets 511 are no longer limited by the Y-shaped push block 508. Among them, each two corresponding magnets 511 are respectively N pole and S pole, so that the two corresponding magnets 511 attract each other and move respectively towards the central position of the bump 509, and then respectively drive the two groups of positioning balls 513 to move into the interior of the bump 509, and further make the multiple positioning balls 513 move out of the circular holes in the card slots 407. Then, the hydraulic rod 502 can be started again to shorten, so as to drive the multiple bumps 509 to separate from the three second gears 404 respectively.

[0029] As Figure 12 shown, it also includes an offshore wind power full-condition intelligent starting generator set system, which includes: a central control unit 6, a wind detection module 7, a front-end perception module 8, a data acquisition module 9, a data analysis module 10, a data processing module 11 and a sensitive unit 12. The central control unit 6 is used to control the wind detection module 7 and the sensitive unit 12 to perform detection and data analysis. The wind detection module 7 is used to measure wind speed information. The front-end perception module 8 is used to collect the temperature, current and vibration data of the fan in real time, as well as the real-time vibration condition of the ball bearing body 304, so as to provide the original information for subsequent analysis and processing. The data acquisition module 9 is used to convert the analog signals collected by the front-end perception module 8 into digital signals, and collect and store them according to a certain sampling frequency and sampling accuracy. The data analysis module 10 is used to analyze the collected data. The data processing module 11 is used to process the collected data and extract relevant characteristic parameters. The sensitive unit 12 is used to sense the acceleration change of the ball bearing body 304.

[0030] In this embodiment, in order to further strengthen the detection of wind power by the intelligent start-up generator set under all working conditions of offshore wind power and the detection of the surface friction force of the ball bearing body 304, thereby reducing the wear of the ball bearing body 304, first, the central control unit 6 sends out an instruction outward. The wind power detection module 7 receives the instruction, analyzes the received signal, and directly interacts with the air flow through the front-end sensing module 8. The wind cups will generate different rotation speeds according to the magnitude of the wind speed, and can accurately sense the change of the wind speed. The data acquisition module 9 collects the signals from the front-end sensing module 8. The data acquisition module 9 obtains these signals in real time to ensure that no key information is lost. The data analysis module 10 processes the original data of wind speed and wind direction collected by the data acquisition module 9, and calculates various meaningful parameters, such as average wind speed, instantaneous wind speed, maximum wind speed, minimum wind speed, average wind direction and wind direction standard deviation, to provide basic data for subsequent analysis and decision-making. Then, according to the data processing module 11, a database system is established to effectively manage the wind power data, and according to the configuration and requirements of the system, the processed data is sent to the designated destination to achieve remote monitoring and management, and different protections for the ball bearing body 304 under different wind speeds. During the detection of the surface friction force of the ball bearing body 304, the central control unit 6 sends out an instruction outward, and the sensitive unit 12 receives the instruction. The conversion element in the sensitive unit 12 converts mechanical changes such as the displacement of the mass block into electrical signals, and converts the mechanical force caused by acceleration into charge signals. After the collected signals are processed and analyzed by the data acquisition module 9, the data analysis module 10, and the data processing module 11, they are transmitted to the remote monitoring and management part to achieve multiple detection protections for the ball bearing body 304 in the intelligent start-up generator of offshore wind power under all working conditions.

[0031] Usage method and working principle of this device: When the full-condition intelligent start generator set in offshore wind power generates wind power, first start the wind detector 2. When it detects that the current offshore wind force is within the standard range, the electric push rod 408 can be started to shorten it, driving the extension rod 409 to move outward from the inside of the internal gear ring 402 to the outside of the fixed ring 401 until it is completely removed, releasing the limit on the internal gear ring 402. The wind wheel 406 will then rotate under the action of the external wind force, driving the switching frame 405 to rotate, and then driving the three second gears 404 to rotate, causing the internal gear ring 402 and the first gear 403 arranged at the central position to rotate, driving the connecting shaft 303 to rotate, and then driving the ball bearing body 304 to rotate. The generator body 302 then converts mechanical energy into electrical energy to achieve energy conversion and ensure the normal operation of the generator body 302. At the same time, start the acceleration sensor 305 to detect the operating state of the ball bearing body 304. When it detects wear inside the ball bearing body 304, the intelligent switch control valve 307 can be opened through an external control system, causing the lubricating oil stored in the sealed tank 306 to flow downward under its own gravity into the inside of the oiling sleeve 308, as Figure 2 shown. Since a plurality of oil inlet holes are provided on the outer surface of the ball bearing body 304, the lubricating oil in the oiling sleeve 308 enters the inside of the ball bearing body 304 along the oil inlet holes to lubricate the ball bearing body 304. When the wind detector 2 detects that the external wind force is too strong, in order to prevent damage to the ball bearing body 304 caused by the strong external wind, when the offshore wind force is too large, first start the infrared sensor 410. When the infrared sensor 410 detects that the circular groove in the internal gear ring 402 and the circular groove in the fixed ring 401 are exactly coincident as shown in Figure 6 , the electric push rod 408 can be immediately started to extend it, driving the extension rod 409 to move inside the internal gear ring 402 to position the internal gear ring 402. The positioning of the internal gear ring 402 causes the three second gears 404 to stop rotating, and the card slots 407 on the surface of each second gear 404 exactly correspond to a plurality of corresponding bumps 509. At this time, the hydraulic rod 502 can be started to extend it, driving the slider 503 to move forward along the outer surface of the connecting shaft 303, so that a plurality of bumps 509 are respectively inserted into the corresponding plurality of card slots 407. Among them, during the process of a plurality of bumps 509 being respectively inserted into a plurality of card slots 407, a plurality of positioning balls 513 are squeezed, driving a plurality of springs 512 to shorten, so that a plurality of positioning balls 513 are respectively inserted into the circular holes inside the bumps 509 as shown in Figure 8 . When the hydraulic rod 502 extends to the longest, a plurality of bumps 509 are exactly inserted into the deepest parts of a plurality of card slots 407, and at this time a plurality of positioning balls 513 just move to the position corresponding to Figure 11At the positions corresponding to the circular holes in the multiple card slots 407 shown, the multiple positioning balls 513 will respectively insert into the circular holes in the corresponding card slots 407 under the action of the self-elastic force of the multiple springs 512 corresponding to them. Combining Figure 8 and Figure 11 shown, the outer diameter of each row of positioning balls 513 gradually decreases from front to back, and the inner diameter of each circular hole groove also gradually decreases from outside to inside. Therefore, during the process of moving the rod, the positioning balls 513 will not be inserted into the circular hole grooves that do not correspond to them during the movement. When the multiple positioning balls 513 are all inserted into the corresponding circular hole grooves, the installation of the multiple bumps 509 is realized, so that the protruding parts in each second gear 404 are doubled. Furthermore, when the wind wheel 406 converts wind energy into mechanical energy and transmits it to the surfaces of the three second gears 404, due to the increase in the protruding parts on the surfaces of the second gears 404, the friction force on the first gear 403 is increased, thereby reducing the rotation speed of the connecting shaft 303, and thus reducing the wear of the ball bearing body 304. When the wind detector 2 detects a decrease in the offshore wind force, the extension rod 409 can be inserted into the inner tooth ring 402 again, and then the three cylinders 506 are started to shorten, respectively driving the three moving frames 507 to move along the inner walls of the three mounting rings 505 in a direction away from the bumps 509, so that the multiple Y-shaped push blocks 508 respectively move out of Figure 8 shown between the outer surfaces of every two corresponding connecting rods 510, so that the two corresponding magnets 511 are no longer limited by the Y-shaped push blocks 508. Among them, every two corresponding magnets 511 are respectively N-pole and S-pole, so that the two corresponding magnets 511 attract each other and move towards the center position of the bump 509 respectively, and then drive the two groups of positioning balls 513 to move towards the inside of the bump 509 respectively, so that the multiple positioning balls 513 respectively move out of the circular holes in the card slots 407. Then, the hydraulic rod 502 can be started again to shorten, thereby driving the multiple bumps 509 to separate from the three second gears 404 respectively. In order to further strengthen the detection of wind force and the detection of the surface friction force of the ball bearing body 304 by the offshore wind power full-condition intelligent start generator set, so as to reduce the wear of the ball bearing body 304. Among them, as Figure 10As shown, a friction bump is provided at the connection between the mounting ring 505 and the mounting rod 504. The purpose is to prevent the mounting ring 505 from rotating and shifting when the multiple bumps 509 in the mounting ring 505 are not in contact with the second gear 404. The central control unit 6 sends out instructions outward. The wind force detection module 7 receives the instructions, analyzes the received signals, directly interacts with the air flow through the front-end sensing module 8. The wind cups will generate different rotational speeds according to the magnitude of the wind speed, and can accurately sense the change of the wind speed. The data acquisition module 9 collects the signals from the front-end sensing module 8. The data acquisition module 9 obtains these signals in real time to ensure that no key information is lost. The data analysis module 10 processes the original data of the wind speed and wind direction collected by the data acquisition module 9, calculates various meaningful parameters, and provides basic data for subsequent analysis and decision-making. Then, according to the data processing module 11, a database system is established to effectively manage the wind force data, and according to the configuration and requirements of the system, the processed data is sent to the specified destination to achieve remote monitoring and management. For the different protections of the ball bearing body 304 under different wind speeds, during the detection of the surface friction force of the ball bearing body 304, the central control unit 6 sends out instructions outward. The sensitive unit 12 receives the instructions. The conversion element in the sensitive unit 12 converts mechanical changes such as the displacement of the mass block into electrical signals, and converts the mechanical force caused by acceleration into charge signals. After the collected signals are processed and analyzed by the data acquisition module 9, the data analysis module 10, and the data processing module 11, they are transmitted to the remote monitoring and management part. Among them, the external control system is electrically connected to the wind force detector 2, the generator body 302, the acceleration sensor 305, the intelligent switch control valve 307, the electric push rod 408, the infrared sensor 410, the hydraulic rod 502, and the cylinder 506.
