Description

TECHNICAL FIELD

[0001] The present application relates to the field of wind power generators, in particular to a laminated wind power generator. BACKGROUND

[0002] The wind power generator is driven by natural wind to rotate the blade, so that the blade drives the gear box, and finally the gear box and the generator set are connected through the installed shaft coupling to transmit power, so as to realize the rotation of the generator set to generate electricity. During the operation of the generator, the output shaft of the generator will rotate at a high speed continuously, which will cause the output shaft to heat up. If the output shaft is overheated for a long time, the service life of the generator will be reduced, so the output shaft needs to be cooled.

[0003] For example, the invention patent with publication number CN119483119B discloses a water-air cooler for wind power generator, which comprises a heat exchanger installed outside the cabin of the wind power generator and a water jacket installed outside the generator. The water jacket is connected with the heat exchanger through a circulating pipe to form a circulating loop. A propeller is rotatably installed in the circulating pipe. The propeller is in transmission connection with the rotating shaft of the generator. The rotating shaft drives the propeller to rotate to realize the closed-loop circulation of the cooling liquid in the circulating pipe.

[0004] For the above-mentioned cases, there are still the following shortcomings:

[0005] During the operation of the wind power generator, the rotating speed of the output shaft of the wind power generator is affected by the wind speed, so the heat generation of the bearing area is not constant. Sometimes it needs to be cooled very strongly, and sometimes it only needs to be cooled moderately or weakly. (Overcooling can cause the temperature of the bearing area to be too low, affecting the performance of the lubricating grease or causing unnecessary thermal stress);

[0006] And the existing cooling method of the output shaft through the water jacket is not convenient for concentrated cooling of the temperature abnormal area of the output shaft (i.e. the position close to the bearing), which can easily affect the service life of the generator.

DETAILED DESCRIPTION

[0052] The following description is provided to enable any person skilled in the art to practice the present application. The preferred embodiments described below are only examples of the present application and other obvious variants can be thought of by those skilled in the art.

[0053] As Figures 1 to 6 shown in the figure, a laminated wind turbine includes:

[0054] The generator body 1, the rotating shaft 101 of the generator body 1 is fixedly sleeved with the heat conducting sleeve 2;

[0055] The spring guide pipe 3 is wound on the surface of the heat conducting sleeve 2;

[0056] The annular oil delivery shell 4 is fixedly connected to the end of the heat conducting sleeve 2 close to the bearing 102, and the outer wall of the annular oil delivery shell 4 is rotatably connected with the first annular sealing plate 5, and the outer side of the first annular sealing plate 5 is fixedly connected with the oil delivery pipe, which is connected with the external oil pumping equipment;

[0057] The annular oil discharge shell 7 is slidably inserted into the surface of the other end of the heat conducting sleeve 2, and the outer wall of the annular oil discharge shell 7 is rotatably connected with the second annular sealing plate 8, and the outer wall of the second annular sealing plate 8 is fixedly connected with the oil discharge pipe, which is connected with the external heat exchanger, and the external heat exchanger delivers the cooled oil to the external oil pumping equipment to form a circulating oil circuit;

[0058] The first push adjusting assembly pushes and adjusts the annular oil discharge shell 7 to move according to the temperature of the rotating shaft 101 close to the bearing 102, so as to adjust the position and pitch of the spring guide pipe 3;

[0059] In the prior art, during the operation of the wind driven generator, the speed of the output shaft of the wind driven generator is affected by the wind speed, so the heat generated in the bearing area is not constant, sometimes requiring very strong cooling, sometimes only requiring moderate or weak cooling, thereby increasing the difficulty of cooling the output shaft, and it is inconvenient to concentrate cooling on the temperature abnormal area of the output shaft, which can easily affect the service life of the generator. The technical scheme can solve the above problems, and the specific operation is as follows:

[0060] During the rotation of the rotating shaft 101 of the generator body 1, the cold oil is transported into the annular oil conveying shell 4 by the external oil pumping equipment (such as an oil pump), the cold oil enters from the oil inlet end of the spring guide pipe 3, moves along the spiral track, so as to reduce the surface temperature of the spring guide pipe 3, thereby reducing the surface temperature of the rotating shaft 101;

[0061] With the continuous movement of the cold oil in the spring guide pipe 3, the oil temperature in the spring guide pipe 3 will continuously rise, and finally the oil is discharged from the oil discharge end of the spring guide pipe 3 into the annular oil discharge shell 7. The heated oil is transported to the external heat exchanger through the oil discharge pipe, and the heated oil is cooled by the heat exchanger, and then transported to the annular oil conveying shell 4 by the external oil pumping equipment, so as to form a complete circulating oil circuit.

[0062] Since the speed of the rotating shaft 101 of the wind driven generator is affected by the wind speed, the faster the speed, the more difficult it is to dissipate the heat generated between the rotating shaft 101 and the bearing 102, so the temperature of the area near the bearing 102 of the rotating shaft 101 is abnormal;

[0063] When the temperature of the area near the bearing 102 of the rotating shaft 101 is abnormal, the first pushing adjusting assembly is used to push the annular oil discharge shell 7 to move towards the annular oil conveying shell 4, on the one hand, the number of turns of the spring guide pipe 3 in the area near the bearing 102 of the rotating shaft 101 is increased, so as to increase the contact area and improve the heat dissipation effect, on the other hand, the pitch is reduced, so that the flow resistance of the cold oil is increased, thereby facilitating the cold oil to flow in the hot spot area for a longer time (increasing the residence time), and the heat on the heat dissipation sleeve pipe 2 is absorbed for a longer time, thereby further improving the heat dissipation effect;

[0064] When the temperature of the area near the bearing 102 of the rotating shaft 101 returns to normal, the first pushing adjusting assembly is used to push the annular oil discharge shell 7 to move away from the annular oil conveying shell 4, so as to reset the spring guide pipe 3, so as to avoid that the overcooling easily causes the temperature of the bearing 102 area to be too low, affecting the performance of the lubricating grease or causing unnecessary thermal stress.

[0065] It should be noted that,

[0066] The generator body 1 is provided with a plurality of stators, and the stator is a coreless structure.

[0067] A plurality of rotor assemblies, the rotor assembly is composed of a magnetic yoke disc and a high magnetic energy product permanent magnet, the magnetic yoke disc is integrally formed with the rotating shaft 101;

[0068] Further,

[0069] The rotor assembly adopts a coreless structure, replaces the tooth slot structure with a soft magnetic material as a core, avoids the influence of the saturation characteristics of the soft magnetic material, solves the tooth slot torque pulsation problem, eliminates the eddy current loss, reduces the rotation pulsation of the generator, improves the efficiency of the generator, and simultaneously reduces the size and weight of the generator body 1;

[0070] Further, the rotor assembly is a double-magnet structure with a magnetic concentration function, increases the air gap magnetic field density, and reduces the magnetic leakage, can realize high power density and torque density, and simultaneously adopts a disc type plane magnetic field, further improves the power density and torque density of the generator through the multi-piece stacking mode of the stator and the rotor.

[0071] As a further embodiment of the application, the first push adjustment assembly comprises:

[0072] The outer annular sealing plate 6 is fixedly connected to the side wall of the annular oil conveying shell 4 at one end;

[0073] The inner annular sealing plate 9 is fixedly connected to the side wall of the annular oil conveying shell 4 at one end, and is slidably connected to the inner wall of the end portion of the outer annular sealing plate 6 at the other end;

[0074] The first rack 17 is fixedly connected to the side wall of the annular oil conveying shell 4;

[0075] The first gear 16 is rotatably connected to the inner wall of the outer annular sealing plate 6, and the first gear 16 is engaged with the first rack 17;

[0076] The rotary drive assembly drives the first gear 16 to rotate according to the temperature of the rotating shaft 101 close to the bearing 102, so as to adjust the position and pitch of the spring guide pipe 3;

[0077] The rotary drive assembly comprises:

[0078] The cylinder body 10 is fixedly connected to the heat-conducting sleeve 2 close to the bearing 102, the piston 11 is sealingly and slidably arranged in the cylinder body 10, and inert gas is filled between the cylinder body 10 and the piston 11;

[0079] The second rack 12 is fixedly connected to the top end of the piston 11, the second gear 13 is engaged with the top end side surface of the second rack 12, and the second gear 13 is rotatably connected to the side wall of the annular oil conveying shell 4;

[0081] Specifically, by setting the cylinder 10, the piston 11 and the second rack 12, when the local temperature of the rotating shaft 101 is abnormal, the temperature of the corresponding position of the heat conduction sleeve 2 is abnormally high, which causes the temperature of the inert gas in the cylinder 10 to rise, the pressure in the cylinder 10 increases (thermal expansion and cold shrink principle), and the piston 11 drives the second rack 12 to move towards the cylinder 10, and the second rack 12 drives the second gear 13 to rotate, so that the first bevel gear 14 rotates, and under the meshing action, the second bevel gear 15 rotates, the first gear 16 rotates, the first gear 16 is engaged with the first rack 17, and drives the first rack 17 to move, so that the annular oil discharge shell 7 drives the inner annular sealing plate 9 to move towards the annular oil conveying shell 4, on the one hand, the number of turns of the spring guide pipe 3 in the area close to the bearing 102 of the rotating shaft 101 is increased, thereby increasing the contact area of the area, improving the heat dissipation effect, and on the other hand, the pitch is reduced, so that the flow resistance of the cold oil is increased, thereby facilitating the cold oil to flow in the hot spot area for a longer time, and the heat on the heat conduction sleeve 2 is absorbed for a longer time, and the heat dissipation effect is further improved;

[0082] When the local temperature of the rotating shaft 101 returns to normal, the pressure in the cylinder 10 returns, and under the above principle, the annular oil discharge shell 7 moves away from the annular oil conveying shell 4, and the spring guide pipe 3 is reset, so as to avoid that the overcooling causes the temperature in the area of the bearing 102 to be too low, which affects the performance of the lubricating grease or causes unnecessary thermal stress;

[0083] In addition, by setting the cylinder 10 and the piston 11, the position and the pitch of the spring guide pipe 3 can be automatically adjusted with the change of the temperature, without the need of sensors, controllers or external power supply, and the device can still work normally in extreme environments (high humidity, low temperature, electromagnetic interference).

[0084] It should be noted that a limiting plate is arranged in the cylinder 10 to prevent the piston 11 from overtraveling under extreme temperature.

[0085] As a further embodiment of the present application, the radius of the first gear 16 is greater than the radius of the first bevel gear 14, the radius of the first bevel gear 14 is greater than the radius of the second gear 13, and the radius of the second gear 13 is greater than the radius of the second bevel gear 15.

[0086] Specifically, by limiting the radius ratio of the first gear 16, the first bevel gear 14, the second gear 13 and the second bevel gear 15, the torque of the first gear 16 is increased, and the stroke of the annular oil discharge shell 7 is amplified under the slight movement of the piston 11, which is beneficial to overcome the elastic damping of the spring guide pipe 3.

[0087] Further, the device further comprises:

[0088] An annular oil injection plate 18 is fixedly connected to the surface of the rotating shaft 101 on the side close to the bearing 102;

[0090] An oil injection assembly injects the cold oil in the annular oil conveying shell 4 to the oil absorbing cotton 1803 during the process of reducing the pitch of the spring guide pipe 3, and spreads the cold oil on the rotating shaft 101 through the oil absorbing cotton 1803;

[0091] The oil injection assembly comprises:

[0092] A partition plate 401 is fixedly connected in the annular oil conveying shell 4 to divide the annular oil conveying shell 4 into a first chamber 402 and a second chamber 403, and the oil conveying pipe is fixedly communicated with the first chamber 402;

[0093] An annular compression plate 404 is sealingly and slidingly connected in the second chamber 403;

[0094] A plurality of oil injection pipes 19 are fixedly connected in an annular array on the side wall of the annular oil conveying shell 4 and communicated with the second chamber 403 at one end, and fixedly connected to the annular oil injection plate 18 at the other end, and each of the oil injection pipes 19 is provided with a first one-way valve;

[0095] A communication pipe 20 is arranged to communicate the first chamber 402 and the second chamber 403, and the communication pipe 20 is provided with a second one-way valve;

[0096] A second pushing and adjusting assembly is rotationally connected with the second gear 13 to push and adjust the movement of the annular compression plate 404;

[0100] A reset spring 23 is fixedly connected to the side wall of the annular compression plate 404 and the partition plate 401 at both ends;

[0101] Specifically, by setting the annular oil injection plate 18 and the oil absorbing cotton 1803, in the process of the piston 11 driving the second rack 12 to move towards the barrel 10 and driving the second gear 13 to rotate (partial temperature anomaly of the rotating shaft 101), the second pushing table 22 rotates synchronously, thereby relatively rotating with the first pushing table 21, and the second guide surface is extruded and pushed by the first guide surface, so that the first pushing table 21 drives the annular compression plate 404 to move, thereby compressing the cold oil in the second cavity 403; at this time, the second one-way valve seals the communication pipe 20, the first one-way valve is closed, the sealing of the oil injection pipe 19 is cancelled, the cold oil is injected into the oil absorbing cotton 1803 on the annular oil injection plate 18 through the oil injection pipe 19, and the cold oil is applied to the rotating shaft 101 through the oil absorbing cotton 1803, which directly contacts a small amount of cold oil with the rotating shaft 101, reduces the temperature of the rotating shaft 101, and on the other hand, improves lubrication and reduces friction, thereby reducing the amount of heat generated;

[0102] In the process of the piston 11 driving the second rack 12 to move away from the barrel 10 (the temperature of the rotating shaft 101 is restored to normal), the second pushing table 22 cancels the pushing of the first pushing table 21, and under the action of the return spring 23, the annular compression plate 404 is reset, at this time, the first one-way valve seals the oil injection pipe 19, the second one-way valve is closed to cancel the sealing of the communication pipe 20, and the cold oil in the first cavity 402 is supplemented into the second cavity 403, preparing for the next cooling of the bearing 102.

[0104] Specifically, by setting the grooves 1801 and the oil holes 1802, the cold oil can be evenly attached to the oil absorbing cotton 1803, so that the cold oil can be evenly distributed on the surface of the rotating shaft 101, and the heat dissipation effect is improved.

[0105] The working principle of the present application is as follows:

[0106] In the process of the rotating shaft 101 of the generator body 1 rotating, the cold oil is transported into the annular oil conveying shell 4 by an external oil pumping device (such as an oil pump), the cold oil enters from the oil inlet end of the spring guide pipe 3, moves along the spiral track, so as to reduce the surface temperature of the heat conduction guide pipe, thereby reducing the surface temperature of the rotating shaft 101;

[0107] With the continuous movement of the cold oil along the spring guide pipe 3, the oil temperature in the spring guide pipe 3 will continue to rise, and finally be discharged from the oil discharge end of the spring guide pipe 3 into the annular oil discharge shell 7. The heated oil is transported to the external heat exchanger through the oil discharge pipe, cooled by the heat exchanger, and then transported to the annular oil conveying shell 4 by the external oil pumping equipment, so as to form a complete circulating oil circuit;

[0108] Since the rotation speed of the rotation shaft 101 of the wind driven generator is affected by the wind speed, the faster the rotation speed is, the more difficult it is to dissipate the heat generated by the friction between the rotation shaft 101 and the bearing 102, thus the temperature of the area close to the bearing 102 of the rotation shaft 101 is abnormal;

[0109] When the temperature of the area close to the bearing 102 of the rotation shaft 101 is abnormal, the first push adjusting assembly is used to push the annular oil discharge shell 7 to move towards the annular oil conveying shell 4, which on the one hand increases the number of turns of the spring guide pipe 3 in the area close to the bearing 102 of the rotation shaft 101, thus increasing the contact area and improving the heat dissipation effect, and on the other hand reduces the pitch, so as to increase the flow resistance of the cold oil, thus being beneficial to prolonging the flow time (increasing the residence time) of the cold oil in the hot spot area, so that more time is available to absorb the heat on the heat conducting sleeve 2, and the heat dissipation effect is further improved;

[0110] When the temperature of the area close to the bearing 102 of the rotation shaft 101 returns to normal, the first push adjusting assembly is used to push the annular oil discharge shell 7 to move away from the annular oil conveying shell 4, so as to reset the spring guide pipe 3, so as to avoid the overcooling to cause the temperature of the bearing 102 area to be too low, thus affecting the performance of the lubricating grease or causing unnecessary thermal stress.

[0111] The above shows and describes the basic principles, main features and advantages of the present application. It should be understood by those skilled in the art that the present application is not limited to the above embodiments, and the above embodiments and descriptions in the specification are only the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the present application.
