When the offshore wind power full-operation-condition intelligent starting generator set is used for wind power generation, lubricating oil is added to the interior of the ball bearing body through an oiling sleeve to provide multiple protection for the ball bearing body. When the wind detector detects that the external wind force is too strong, three raised portions are added to the surface of the second gear.

Description

Technical Field

[0001] The present invention relates to the technical field of generator sets, and in particular to an offshore wind power full-operating-condition intelligent starting generator set. Background Art

[0002] The offshore wind power full-operating condition intelligent starting generator set uses wind power generation. It is one of the core equipment in the offshore wind power generation system and mainly relies 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 rotor inside the generator to move. The rotor cuts the magnetic flux lines 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. In addition, the full-operating condition intelligent starting emphasizes that the generator can optimize the startup and operation process through the intelligent control system under various complex offshore working conditions to improve power generation efficiency and equipment reliability and stability.

[0003] Existing offshore wind power full-operation-condition intelligent starting generator sets adjust the generator speed in real time according to the offshore wind conditions through the regulation of the intelligent control system during the process of wind power generation. However, when encountering strong winds, the strong winds will cause the wind rotor part to be subjected to greater radial force, which is transmitted to the ball bearings through the rotating shaft, resulting in an increase in the radial load borne by the ball bearings, thereby causing the contact stress between the balls and the raceways to exceed the normal level, accelerating the wear of the balls and the raceways, and easily leading to damage to the ball bearings.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. When it is necessary to use an offshore wind power full-operation condition intelligent starting generator set for wind power generation, 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 oiling sleeve. When the wind detector detects that the external wind is too strong, by adding three raised parts on the surface of the second gear, when the wind wheel converts wind power into mechanical energy and transmits it to the three second gear surfaces, the friction on the first gear is increased due to the increase in the raised parts on the second gear surfaces, thereby reducing the rotation rate of the connecting shaft.

[0020] 3. To reduce the wear on the ball bearing body, the central control unit first sends out instructions, which are then received by the wind detection module and the sensitive unit. After being processed and analyzed by the data acquisition module, data analysis module, and data processing module, the instructions are transmitted to the remote monitoring and management part, thus realizing multiple detection and protection of the ball bearing body in the offshore wind power full-operating condition intelligent starting generator.

One end of the liquid outlet pipe is fixedly connected to an oil sleeve 308. The inner wall of the oil sleeve 308 contacts the outer surface of the ball bearing body 304. One end of the connecting shaft 303 is movable and penetrates the outside of the cabin 301. The 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 cabin 301. The hydraulic rod 502 The outer surface of the wind energy capture component 4 is fixedly connected to the outer surface of the nacelle 301 by screws. The outer surface of the fixed ring 401 is fixedly connected to the outer surface of the nacelle 301. The inner wall of the fixed ring 401 is rotatably connected to the inner gear ring 402. A first gear 403 is fixed to one end of the connecting shaft 303. The outer surface of the first gear 403 is meshed with three second gears 404. The outer surfaces of the three second gears 404 are all meshed with the outer surface of the inner gear ring 402. The outer surfaces of the three second gears 404 are movably connected with a switching frame 405 through an extension shaft, and a wind wheel 406 is fixed to the outer surface of the switching frame 405. The outer surfaces of the three second gears 404 are provided with multiple slots 407, and the inner walls of the multiple slots 407 slide with the outer surfaces of the multiple protrusions 509 respectively. An electric push rod 408 is set on the outer surface of the fixed ring 401 through an auxiliary frame, and an extension rod 409 is fixedly installed on one end of the electric push rod 408, and an infrared sensor 410 is set on the inner wall of the extension rod 409.

[0037] In this embodiment, when it is necessary to use the offshore wind power full-condition intelligent starting generator set for wind power generation, due to the large fluctuation of offshore wind force, the wind detector 2 is first started during operation. Among them, the wind detector 2 uses the rotation of the propeller in the wind to measure the wind speed. The rotation plane of the propeller is perpendicular to the wind direction. When the wind blows the propeller, the propeller rotates, and its speed is proportional to the wind speed. The propeller speed is detected by the sensor installed on the propeller shaft, thereby obtaining the wind speed. When the wind detector 2 detects that the current offshore wind force is within the standard range, it can be The electric push rod 408 is started to shorten, driving the extension rod 409 to move away from the inner gear ring 402 and toward the outside of the fixed ring 401 until it is completely moved out, releasing the limit on the inner gear ring 402. The wind wheel 406 will rotate under the action of the external wind force, thereby driving the switching frame 405 to rotate, and then driving the three second gears 404 to rotate, so that the inner gear ring 402 and the first gear 403 set at the center position rotate, driving the connecting shaft 303 to rotate, and then driving the ball bearing body 304 to rotate, and then the mechanical energy is converted into the generator body 302. The ball bearing body 304 is used to convert the connecting shaft 303 into electrical energy, thereby realizing energy conversion. The connecting shaft 303 maintains a stable position and posture during operation through the action of the ball bearing body 304, providing reliable support for the connecting shaft 303, ensuring that the rotating shaft can rotate stably around its axis, maintaining the relative position relationship between the internal components of the generator body 302, and ensuring the normal operation of the generator body 302. At the same time, the acceleration sensor 305 is started to detect the operating status of the ball bearing body 304. When the ball bearing body 304 is worn, the worn part will cause the intensity and frequency characteristics of the vibration to change. The sensitive part of the acceleration sensor 305 will sense these vibration accelerations and compare the extracted signal features with the pre-established normal bearing vibration feature library and the bearing vibration feature library with known wear degree and type, so as to track the development process of bearing wear. When wear is detected 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 to the inside of the oiling sleeve 308 under the action of its own gravity. Figure 2 As shown, since the outer surface of the ball bearing body 304 is provided with a plurality of oil inlet holes, the lubricating oil in the oil sleeve 308 enters the interior of the ball bearing body 304 along the oil inlet holes, thereby lubricating the ball bearing body 304 and effectively protecting it, thereby preventing the ball bearing body 304 from being damaged by friction.

[0038] like Figure 1 and Figure 4-11As shown, an offshore wind power full-operating condition intelligent starting generator set includes a support structure 1, an energy conversion component 3 for converting mechanical energy into electrical energy is provided at the top of the support structure 1, a wind energy capture component 4 for converting wind energy into mechanical energy is provided on the outer surface of the energy conversion component 3, a load adjustment component 5 is provided on the outer surface of the wind energy capture component 4, the load adjustment component 5 includes a telescopic rod 501 and a hydraulic rod 502, a slider 503 is fixedly installed between one end of the telescopic rod 501 and the hydraulic rod 502, three mounting rods 504 are fixed on the outer surface of the slider 503, the outer surfaces of the three mounting rods 504 are movably sleeved with mounting rings 505, the inner walls of the three mounting rings 505 are each provided with a cylinder 506 near the center, one end of each of the three cylinders 506 is fixedly installed with a movable frame 507, and the three movable frames 50 A plurality of Y-shaped push blocks 508 are fixedly installed on the outer surface of 7 near the outer edge, a plurality of protrusions 509 are fixedly connected to the outer surfaces of the three mounting rings 505, and the inner walls of the plurality of protrusions 509 are slidably connected to two connecting rods 510, and a plurality of springs 512 are provided on the outer surface of the other side of the plurality of connecting rods 510, and a positioning ball 513 is provided on one end of the plurality of springs 512. A magnet 511 is fixed on the outer surface of one side of the plurality of connecting rods 510, and the outer surfaces of the plurality of movable frames 507 are respectively slidably connected to the inner walls of the plurality of mounting rings 505, and one end of the plurality of springs 512 is respectively movable to penetrate the outside of the plurality of protrusions 509, and one end of the plurality of springs 512 is respectively fixedly connected to the outer surfaces of the plurality of connecting rods 510, and the other ends of the plurality of springs 512 are respectively fixedly connected to the outer surfaces of the plurality of positioning balls 513.

[0039] In this embodiment, when the wind detector 2 detects that the external wind is too strong, in order to prevent the external strong wind from causing damage to the ball bearing body 304, when the wind is too strong at sea, the infrared sensor 410 is first activated. Figure 6 When the circular groove in the inner gear ring 402 coincides 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 toward the inside of the inner gear ring 402, thereby positioning the inner gear ring 402. The positioning of the inner gear ring 402 makes the three second gears 404 no longer rotate, and the groove 407 on the surface of each second gear 404 corresponds exactly to the corresponding multiple protrusions 509. 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 multiple protrusions 509 are respectively inserted into the corresponding multiple grooves 407. In the process of the multiple protrusions 509 being respectively inserted into the multiple grooves 407, the multiple positioning balls 513 are squeezed, driving the multiple springs 512 to shorten, so that the multiple positioning balls 513 are respectively inserted into the inner grooves 407. Figure 8When the hydraulic rod 502 is extended to its longest position, the plurality of protrusions 509 are inserted into the deepest part of the plurality of slots 407, and the plurality of positioning balls 513 are moved to the position corresponding to the position shown in FIG. Figure 11 The plurality of positioning balls 513 are inserted into the circular holes in the corresponding slots 407 under the elastic force of the plurality of springs 512, wherein the plurality of positioning balls 513 are inserted into the circular holes in the corresponding slots 407 respectively. Figure 8 and Figure 11 As shown, the outer diameter of each row of positioning balls 513 is gradually reduced from front to back, and the inner diameter of each circular hole groove is also gradually reduced from outside to inside. Therefore, when the positioning balls 513 move the rod, they will not be inserted into the circular hole grooves that do not correspond to them. When multiple positioning balls 513 are inserted into the corresponding circular hole grooves, the installation of multiple protrusions 509 is realized, so that the raised portion in each second gear 404 is doubled, and then when the wind wheel 406 converts wind power into mechanical energy and transmits it to the surfaces of the three second gears 404, the raised portion on the surface of the second gear 404 increases, thereby increasing the friction on the first gear 403, thereby reducing the rotation rate of the connecting shaft 303, thereby reducing the wear on the ball bearing body 304, effectively protecting the ball bearing body 304, and solving the problem in the existing technology that most offshore wind power full-condition intelligent starting generator sets are prone to damage to roller bearings when encountering strong winds.

[0040] like Figure 1 and Figure 7-10 As shown, an offshore wind power full-operation condition intelligent starting generator set includes a support structure 1, an energy conversion component 3 for converting mechanical energy into electrical energy is set on the top of the support structure 1, a wind energy capture component 4 for converting wind energy into mechanical energy is set on the outer surface of the energy conversion component 3, a load adjustment component 5 is set on the outer surface of the wind energy capture component 4, the load adjustment component 5 includes a telescopic rod 501 and a hydraulic rod 502, a slider 503 is fixedly installed between one end of the telescopic rod 501 and the hydraulic rod 502, and the slider 503 is fixed between one end of the telescopic rod 501 and the hydraulic rod 502. Three mounting rods 504 are fixed on the outer surface, and the outer surfaces of the three mounting rods 504 are movably provided with mounting rings 505. Cylinders 506 are provided near the center of the inner walls of the three mounting rings 505, and a moving frame 507 is fixedly installed at one end of the three cylinders 506. A plurality of Y-shaped push blocks 508 are fixedly installed on the outer surfaces of the three moving frames 507 near the outer edges. The outer surfaces of the three mounting rings 505 are fixedly connected with a plurality of protrusions 509, and the inner walls of the plurality of protrusions 509 are slidably connected to two connecting rods 510.

[0041] In this embodiment, when the wind detector 2 detects that the wind force at sea decreases, the extension rod 409 can be inserted into the inner gear ring 402 again, and then the three cylinders 506 are activated to shorten the inner gear ring 402, thereby driving the three moving frames 507 to move along the inner walls of the three mounting rings 505 in a direction away from the protrusion 509, thereby causing the multiple Y-shaped push blocks 508 to move out of the inner gear ring 402. Figure 8 Between the outer surfaces of each two corresponding connecting rods 510 shown, the two corresponding magnets 511 are no longer limited by the Y-shaped push block 508, wherein each two corresponding magnets 511 are respectively N-level and S-level, so that the two corresponding magnets 511 attract each other and move toward the center position of the protrusion 509, respectively, and then drive the two groups of positioning balls 513 to move toward the inside of the protrusion 509, respectively, so that the multiple positioning balls 513 are respectively moved out of the circular holes in the slot 407, and then the hydraulic rod 502 can be started again to shorten it, thereby driving the multiple protrusions 509 to separate from the three second gears 404 respectively.

[0042] like Figure 12 As shown, it also includes an offshore wind power full-operating condition intelligent starting generator set system, which includes: a central control unit 6, a wind detection module 7, a front-end sensing 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 sensing module 8 is used to collect temperature, current and vibration data of the wind turbine in real time, as well as the real-time vibration of the ball bearing body 304, to provide original information for subsequent analysis and processing. The data acquisition module 9 is used to convert the analog signal collected by the front-end sensing module 8 into a digital signal, and collect and store it 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.

[0043] In this embodiment, in order to further strengthen the detection of wind force and the surface friction of the ball bearing body 304 by the offshore wind power full-operation intelligent starting generator set, thereby reducing the wear of the ball bearing body 304, first, the central control unit 6 sends out instructions, the wind force detection module 7 receives the instructions, analyzes the received signals, and directly interacts with the air flow through the front-end sensing module 8. The wind cup will produce different rotation speeds depending on the wind speed and can accurately sense the change in wind speed. The signals from the front-end sensing module 8 are collected by the data acquisition module 9. 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 wind speed and wind direction data collected by the data acquisition module 9 to calculate various meaningful parameters, such as average wind speed, instantaneous wind speed, maximum wind speed, minimum wind speed, wind direction average value and wind direction standard deviation. , providing basic data for subsequent analysis and decision-making, and then establishing a database system according to the data processing module 11 to effectively manage wind data, and send the processed data to the designated destination according to the system configuration and requirements, to achieve remote monitoring and management, and different protection of the ball bearing body 304 for different wind speeds. In the process of detecting the surface friction of the ball bearing body 304, the central control unit 6 sends out instructions, and the sensitive unit 12 receives the instructions. The conversion element in the sensitive unit 12 will convert mechanical changes such as the displacement of the mass block into electrical signals, and convert the mechanical force caused by acceleration into charge signals. The collected signals are then processed and analyzed by the data acquisition module 9, the data analysis module 10, and the data processing module 11, and then transmitted to the remote monitoring and management part, realizing multiple detection and protection of the ball bearing body 304 in the intelligent starting generator of offshore wind power under all working conditions.

[0044] The method of use and working principle of this device: When the offshore wind power generator set is intelligently started under full working conditions to generate wind power, the wind detector 2 is first started. When it detects that the current offshore wind force is within the standard range, the electric push rod 408 is started to shorten it, driving the extension rod 409 to move away from the inner gear ring 402 and toward the outside of the fixed ring 401 until it is completely moved out, releasing the limit on the inner gear ring 402. The wind wheel 406 will rotate under the action of the external wind force, thereby driving the switching frame 405 to rotate, and then driving the three second gears 404 to rotate, so that the inner gear ring 402 and the gears arranged on the inner gear ring 402 are rotated. The first gear 403 at the center rotates, driving the connecting shaft 303 to rotate, and then driving the ball bearing body 304 to rotate, and then the mechanical energy is converted into electrical energy through the generator body 302, realizing energy conversion and ensuring the normal operation of the generator body 302. At the same time, the acceleration sensor 305 is started to detect the operating status of the ball bearing body 304. When wear is detected 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 to the inside of the oiling sleeve 308 under the action of its own gravity. Figure 2 As shown, since the outer surface of the ball bearing body 304 is provided with a plurality of oil inlet holes, the lubricating oil in the oil sleeve 308 enters the interior of the ball bearing body 304 along the oil inlet holes to achieve lubrication of the ball bearing body 304. When the wind detector 2 detects that the external wind is too strong, in order to prevent the external strong wind from causing damage to the ball bearing body 304, when the wind is too strong at sea, the infrared sensor 410 is first started. When the infrared sensor 410 detects that the wind is too strong, the infrared sensor 410 is first started. Figure 6 When the circular groove in the inner gear ring 402 coincides 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 toward the inside of the inner gear ring 402, thereby positioning the inner gear ring 402. The positioning of the inner gear ring 402 makes the three second gears 404 no longer rotate, and the groove 407 on the surface of each second gear 404 corresponds exactly to the corresponding multiple protrusions 509. 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 multiple protrusions 509 are respectively inserted into the corresponding multiple grooves 407. In the process of the multiple protrusions 509 being respectively inserted into the multiple grooves 407, the multiple positioning balls 513 are squeezed, driving the multiple springs 512 to shorten, so that the multiple positioning balls 513 are respectively inserted into the inner grooves 407. Figure 8 When the hydraulic rod 502 is extended to its longest position, the plurality of protrusions 509 are inserted into the deepest part of the plurality of slots 407, and the plurality of positioning balls 513 are moved to the position corresponding to the position shown in FIG. Figure 11The plurality of positioning balls 513 are inserted into the circular holes in the corresponding slots 407 under the elastic force of the corresponding plurality of springs 512. Figure 8 and Figure 11 As shown, the outer diameter of each row of positioning balls 513 is gradually reduced from front to back, and the inner diameter of each circular hole groove is also gradually reduced from outside to inside. Therefore, when the positioning balls 513 move the rod, they will not be inserted into the circular hole grooves that do not correspond to them. When multiple positioning balls 513 are inserted into the circular hole grooves corresponding to them, the installation of multiple protrusions 509 is achieved, so that the protrusions in each second gear 404 are doubled, thereby making the wind wheel 406 convert wind power into mechanical energy and transmit it to the three second gears 406. 4, due to the increase of the raised portion on the surface of the second gear 404, the friction force on the first gear 403 is increased, thereby reducing the rotation rate of the connecting shaft 303, thereby reducing the wear on the ball bearing body 304. When the wind detector 2 detects that the wind force at sea is reduced, the extension rod 409 can be inserted into the interior of the inner gear ring 402 again, and then the three cylinders 506 are activated to shorten it, thereby driving the three moving frames 507 to move along the inner walls of the three mounting rings 505 in a direction away from the protrusion 509, thereby causing the multiple Y-shaped push blocks 508 to move out respectively. Figure 8 As shown, between the outer surfaces of each two corresponding connecting rods 510, the two corresponding magnets 511 are no longer limited by the Y-shaped push block 508, wherein each two corresponding magnets 511 are respectively N-level and S-level, so that the two corresponding magnets 511 attract each other and move toward the center position of the protrusion 509, respectively, thereby driving the two groups of positioning balls 513 to move toward the inside of the protrusion 509, respectively, so that the multiple positioning balls 513 are respectively moved out of the circular holes in the card slot 407, and then the hydraulic rod 502 can be started again to shorten it, thereby driving the multiple protrusions 509 to separate from the three second gears 404 respectively. In order to further strengthen the detection of wind force and the detection of surface friction of the ball bearing body 304 by the intelligent start-up generator set of offshore wind power in all working conditions, thereby reducing the wear on the ball bearing body 304, wherein, as Figure 10As shown, a friction protrusion is provided at the connection between the mounting ring 505 and the mounting rod 504, the purpose of which is to prevent the multiple protrusions 509 in the mounting ring 505 from rotating and displacing when the multiple protrusions 509 in the mounting ring 505 are not in contact with the second gear 404. The central control unit 6 sends out instructions, the wind detection module 7 receives the instructions, analyzes the received signals, and directly interacts with the air flow through the front-end sensing module 8. The wind cup will produce different rotation speeds depending on the size of the wind speed and can accurately sense the change in wind speed. The signals from the front-end sensing module 8 are collected by the data acquisition module 9. 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, calculates various meaningful parameters, and provides basic data for subsequent analysis and decision-making. Then, a database system is established according to the data processing module 11 , effectively manage wind data, and send the processed data to the designated destination according to the system configuration and requirements, realize remote monitoring and management, and provide different protection for the ball bearing body 304 at different wind speeds. In the process of detecting the surface friction of the ball bearing body 304, the central control unit 6 sends out instructions, and the sensitive unit 12 receives the instructions. The conversion element in the sensitive unit 12 will convert mechanical changes such as the displacement of the mass block into electrical signals, and convert the mechanical force caused by acceleration into charge signals. The collected signals are then processed and analyzed by the data acquisition module 9, the data analysis module 10, and the data processing module 11, and then transmitted to the remote monitoring and management part. The external control system is electrically connected to the wind 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.
