[0030] In the present invention, the flow value of the liquid oil in the oil tank is predicted based on the production data, the gravity change curve and the machine learning model, so that the weight of the lifting seat is continuously increased during the process of winding the coil on the inner side of the wind turbine stator, so that the lifting seat and the wind turbine stator are kept balanced. In this way, the load and energy consumption of the driving mechanism can be minimized, the cost of winding the wind turbine stator coil can be reduced, the life of the driving mechanism can be increased, and the maintenance cost of the vertical winding device of the high-power wind turbine module coil can be reduced.

DETAILED DESCRIPTION
[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0045] Embodiment 1:
[0046] like Figure 1-Figure 3 As shown, the present invention discloses a vertical winding device for a high-power wind power module coil, comprising a positioning base 1, which is used to clamp a wind power stator 5, a vertical winding mechanism 2 is arranged on the top of the positioning base 1, and a feeding conveyor belt 3 and a discharging conveyor belt 4 are respectively arranged on both sides of the positioning base 1, and a copper wire reel is also required to be arranged on the side of the positioning base 1, and the copper wire reel is wound with copper wire for manufacturing the coil. The specifications, quantity and setting position of the copper wire reel are adaptively selected by technical personnel in this field according to the actual production situation of the vertical winding device for the high-power wind power module coil. In addition, it should be noted that a tension mechanism is also required to be arranged between the copper wire reel and the vertical winding mechanism 2. When the copper wire reel provides copper wire to the vertical winding mechanism 2, the stability of the copper wire tension is maintained by the tension mechanism. The tension mechanism is adaptively selected by technical personnel in this field according to the vertical winding mechanism 2 and the specifications of the copper wire. For example, an automatic tension controller can be arranged on the rotating shaft of the copper wire reel, and the stability of the copper wire tension is controlled by the automatic tension controller.
[0047] like Fig.10 As shown, the vertical winding mechanism 2 includes a lifting platform 21, and a lifting seat 24 is provided on the inner side of the lifting platform 21. The lifting seat 24 offsets the gravity of the wind turbine stator 5 while winding the coil on the inner side of the wind turbine stator 5. An oil tank 23 is provided on the top of the lifting platform 21. The oil tank 23 transports liquid oil to the lifting platform 21 according to the change of gravity of the wind turbine stator 5.
[0048] It should be noted that a top plate 22 is provided on the side of the oil tank 23, and the top plate 22 is fixed on the top of the positioning base 1. A driving mechanism 25 is provided between the bottom surface of the top plate 22 and the lifting seat 24. The function of the driving mechanism 25 is to drive the lifting seat 24 so that the lifting seat 24 can be freely lifted and lowered on the inner side of the lifting platform 21. The driving mechanism 25 can be a hydraulic push rod or an electric push rod, which can be adaptively selected by technical personnel in this field according to the working scenario of the lifting seat 24.
[0049] like Figure 4 and Figure 5 As shown, the positioning base 1 includes a fixed base 11, the top surface of the fixed base 11 is rotatably connected to a rotating table 12, the center position of the top surface of the rotating table 12 is fixedly connected to a limiting cylinder 14, the edge position of the top surface of the rotating table 12 is fixedly connected to a limiting column 121, and an automatic loading and unloading mechanism 13 is arranged on the side of the limiting column 121.
[0050] It should be noted that a motor can be arranged inside the fixed base 11, and a rotating shaft is installed between the rotating table 12 and the fixed base 11. The rotating shaft is used to drive the rotating table 12. The output shaft of the motor engages with the side of the rotating shaft through gears. When the motor is turned on, the output shaft of the motor can drive the rotating shaft through the gears, and the rotating shaft drives the rotating table 12, thereby realizing the automatic rotation of the rotating table 12.
[0051] like Figure 1 and Figure 5 As shown, the automatic loading and unloading mechanism 13 includes a lifting slider 131 , the inner side of which is fixedly connected to a horizontal track 132 , the inner side of which is provided with a clamping mechanism 133 , and the bottom surface of the lifting slider 131 is provided with a pushing mechanism 134 .
[0052] It should be noted that a cylindrical channel matching the limiting column 121 runs through the surface of the lifting slider 131 to ensure that the lifting slider 131 can slide in the vertical direction on the side of the limiting column 121. The pushing mechanism 134 is fixed on the side of the limiting column 121. The function of the pushing mechanism 134 is to control the vertical position of the lifting slider 131. The pushing mechanism 134 can be a hydraulic push rod or an electric push rod. The clamping mechanism 133 is used to clamp the wind turbine stator 5.
[0053] like Figure 1 , Figure 5 and Figure 6As shown, the clamping mechanism 133 includes a clamping ring 1331, and track sliders 1332 are fixedly connected at both ends of the clamping ring 1331. The track sliders 1332 match the horizontal track 132 to ensure that the track sliders 1332 can slide freely along the track direction in the horizontal track 132. The outer center position of the clamping ring 1331 is fixedly connected to an oil cylinder 1333, and the inner center position of the clamping ring 1331 is fixedly connected to a first clamping block 1334. A second clamping block 1335 is provided on the inner side of the track slider 1332.
[0054] It should be noted that the function of the oil cylinder 1333 is to drive the second clamping block 1335. Specifically, a cylindrical cavity is opened inside the track slider 1332. A round rod matching the cylindrical cavity is fixedly connected to the inner end of the second clamping block 1335. The delivery end of the oil cylinder 1333 is connected to the cylindrical cavity through a pipeline. When the wind turbine stator 5 needs to be clamped, the clamping ring 1331 can be moved to the side of the wind turbine stator 5, and then the oil cylinder 1333 is opened. The oil cylinder 1333 can deliver hydraulic oil to the cylindrical cavity. The hydraulic oil in the cylindrical cavity drives the second clamping block 1335 through the round rod, so that the second clamping block 1335 can act on the side of the wind turbine stator 5 and fix the wind turbine stator 5 by friction. In addition, it should be noted that in order to increase the friction between the second clamping block 1335 and the side of the wind turbine stator 5, a rubber side can be set on the outer side of the second clamping block 1335. The specific process of loading and unloading the wind turbine stator 5 is as follows:
[0055] First, the feed conveyor belt 3 conveys the unprocessed wind turbine stator 5 to the bottom of the horizontal track 132. The horizontal track 132 can adopt an electric slide rail to ensure that the track slider 1332 can slide freely in the horizontal track 132. At this time, the track slider 1332 can be controlled by the horizontal track 132 to move the clamping ring 1331 to the position of the wind turbine stator 5. Then, the height of the clamping ring 1331 is controlled by the pushing mechanism 134 to make the clamping ring 1331 drop to the middle position of the side of the wind turbine stator 5.
[0056] Then open the oil cylinder 1333, and the oil cylinder 1333 transports the hydraulic oil to the cylindrical cavity. The hydraulic oil in the cylindrical cavity drives the second clamping block 1335 through the round rod, so that the second clamping block 1335 can act on the side of the wind turbine stator 5, fix the wind turbine stator 5 by friction, and then control the height of the clamping ring 1331 through the pushing mechanism 134, so that the clamping ring 1331 drives the wind turbine stator 5 to rise, and then translates the wind turbine stator 5 to make the wind turbine stator 5 enter the limiting cylinder 14.
[0057] After the wind turbine stator 5 entering the limiting cylinder 14 completes the coil processing, the rotating table 12 rotates 90° to rotate the horizontal track 132 to be directly above the discharge conveyor belt 4, and then the wind turbine stator 5 is transported to the top surface of the discharge conveyor belt 4 through the clamping mechanism 133, completing the transportation of one wind turbine stator 5. The wind turbine stator 5 is transported repeatedly in this way until the processing of all wind turbine stators 5 is completed.
[0058] Embodiment 2:
[0059] like Figure 1 , Figure 7 , Figure 8 and Fig. 9 As shown, a winding seat 141 is provided on the inner side of the limiting cylinder 14, a cylinder 142 is provided on the bottom surface of the winding seat 141, and at least three groups of clamping hooks 144 are provided on the side edge of the winding seat 141. The three groups of clamping hooks 144 are movably installed on the side of the winding seat 141 through torsion springs.
[0060] It should be noted that the three groups of clamping hooks 144 are equidistantly arranged on the side of the winding seat 141. When the wind turbine stator 5 is placed on the top surface of the winding seat 141, the pneumatic push rod 143 arranged inside the winding seat 141 can be opened, and the pneumatic push rod 143 will push the clamping hook 144 to Fig. 9 For example, the clamping hook 144 will rotate clockwise. It should also be noted that a barb groove needs to be opened on the side of the wind turbine stator 5 near the clamping hook 144, so that after the clamping hook 144 rotates clockwise, it will be stuck in the barb groove, thereby locking the position of the wind turbine stator 5. When the inner coil of the wind turbine stator 5 is wound, the pneumatic push rod 143 can be closed. At this time, the clamping hook 144 will automatically rotate counterclockwise under the torque force of the torsion spring and disengage from the barb groove on the side of the wind turbine stator 5, ensuring that the wind turbine stator 5 can be automatically unlocked. At this time, the automatic loading and unloading mechanism 13 can freely carry the wind turbine stator 5.
[0061] Embodiment 3:
[0062] like Figure 1 , Fig.10 As shown, a sealing block 244 is provided in the middle position of the top surface of the lifting seat 24, an oil pipeline 26 is connected between the oil tank 23 and the lifting seat 24, a gravity groove matching the sealing block 244 is opened in the middle position of the top surface of the lifting seat 24, and the end of the oil pipeline 26 away from the oil tank 23 passes through the lifting seat 24 and is connected with the bottom end of the gravity groove.
[0063] It should be noted that an oil pump is provided inside the oil tank 23, and the oil pump can press the liquid oil in the oil tank 23 into the gravity tank through the oil delivery pipe 26. The liquid oil entering the gravity tank will squeeze the sealing block 244, so that the sealing block 244 automatically rises. As the hydraulic oil continues to enter the gravity tank, the overall gravity of the lifting seat 24 will continue to rise.
[0064] At least two groups of oil cylinders 242 are arranged on the top surface of the lifting platform 21 near the side of the lifting seat 24. The top surface of the lifting seat 24 is fixedly connected with a piston 243 matching the oil cylinder 242. The bottom end of the oil cylinder 242 is connected to the bottom end of the oil cylinder 142 through an oil pipe.
[0065] It should be noted that when the lifting seat 24 is winding the coil on the inner side of the wind turbine stator 5, the copper wire reel will continuously provide copper wire to the lifting seat 24. A winding rod 241 is installed on the bottom surface of the lifting seat 24. Figure 4 As shown, the bottom surface of the lifting seat 24 is provided with several groups of movable grooves, the winding rod 241 can move freely in the movable grooves, a channel is opened inside the winding rod 241, and a channel can also be opened on the top surface of the lifting seat 24 near the copper wire drum. The copper wire on the copper wire drum is transported to the inner side of the wind turbine stator 5 through the channels opened on the lifting seat 24 and the winding rod 241.
[0066] A winding rod 241 can be installed in the movable groove on the bottom surface of the lifting seat 24. The more winding rods 241 there are, the higher the efficiency of winding the coil of the lifting seat 24 will be. Multiple winding rods 241 need to be symmetrically installed on the bottom surface of the lifting seat 24. The installation quantity and position of the winding rods 241 are adaptively set by technical personnel in this field according to the specifications of the wind turbine stator 5.
[0067] like Figure 1-Figure 10 As shown, the specific process of winding the coil by the lifting seat 24 is as follows:
[0068] First, the winding rod 241 will be above the wind turbine stator 5, and the copper wire head needs to be fixed on the top of the wind turbine stator 5, and then the driving mechanism 25 is turned on. The driving mechanism 25 will push the lifting seat 24 to move the lifting seat 24 downward. During the downward movement of the lifting seat 24, the lifting seat 24 will drive the piston 243 to move downward synchronously, and the downward moving piston 243 will squeeze the hydraulic oil in the oil cylinder 242.
[0069] Since the bottom end of the oil cylinder 242 is connected to the bottom end of the second oil cylinder 142 through the oil pipe, the hydraulic oil in the oil cylinder 242 will enter the second oil cylinder 142 through the oil pipe, and the hydraulic oil entering the second oil cylinder 142 will push the winding seat 141, so that the winding seat 141 can drive the wind turbine stator 5 to move upward. Those skilled in the art can preset the weight of the lifting seat 24 so that the weight of the lifting seat 24 can offset the weight of the wind turbine stator 5 and the winding seat 141, which will greatly reduce the load of the driving mechanism 25;
[0070] Furthermore, since the winding seat 141 drives the wind turbine stator 5 to move upward while the lifting seat 24 moves downward, the movement range of the lifting seat 24 is reduced by half, which can greatly improve the efficiency of winding the coil by the lifting seat 24.
[0071] While the winding rod 241 continuously winds the coil, the winding rod 241 needs to move in the movable groove to make the winding of the coil more uniform. Therefore, a screw nut structure needs to be set in the movable groove. The nut is fixed inside the winding rod 241. The screw is installed in the movable groove through a bearing. One end of the screw is connected to the output shaft of the motor through a coupling. When the motor is turned on, the motor will drive the screw to rotate. The movable groove is set to a rectangle. The top of the winding rod 241 is connected to a rectangular slider. The nut can be fixedly installed inside the rectangular slider. In this way, the rotating screw can drive the rectangular slider through the nut, and the rectangular slider drives the winding rod 241, so that the winding rod 241 can move freely in the movable groove.
[0072] It should also be noted that when winding the coil, the bottom end of the winding rod 241 needs to be wound in a circle, and the winding rod 241 can only move up and down. Therefore, when the bottom end of the winding rod 241 moves to the top and bottom ends of the wind turbine stator 5, the wind turbine stator 5 needs to be driven by the rotating table 12 to rotate the wind turbine stator 5 by a certain angle. The size of the angle is adaptively adjusted by technical personnel in this field according to the size of the coil inside the wind turbine stator 5. In this way, the winding rod 241 can wind the copper wire around the inside of the wind turbine stator 5 to form a coil.
[0073] Embodiment 4:
[0074] like Figure 1-Figure 11 As shown, the present invention discloses a method for vertically winding a coil of a high-power wind power module, which is implemented based on a vertically winding device for a coil of a high-power wind power module in Example 3, and includes the following steps:
[0075] A historical training data set is collected in advance, and the historical training data set includes N groups of training data, each group of training data includes feature data and label data, wherein the feature data includes winding speed, pressure data and temperature data.
[0076] The winding speed is the winding speed of the inner coil of the wind turbine stator 5 when collecting each set of training data. It should be noted that the winding speed of the inner coil of the wind turbine stator 5 is the speed at which the winding rod 241 cooperates with the wind turbine stator 5 to wind one circle of coil on the inner side of the wind turbine stator 5.
[0077] The pressure data is the pressure value of the liquid oil in the oil tank 23 when collecting each set of training data. It should be noted that a pressure sensor can be installed inside the oil tank 23 or inside the oil pipeline 26, and the pressure value of the liquid oil in the oil tank 23 can be directly obtained through the pressure sensor.
[0078] The temperature data is the temperature value of the liquid oil in the oil tank 23 when collecting each set of training data. It should be noted that a temperature sensor can be installed inside the oil tank 23 or inside the oil pipeline 26, and the temperature value of the liquid oil in the oil tank 23 can be directly obtained through the temperature sensor.
[0079] The label data is the flow value of the liquid oil in the oil tank 23 when collecting each set of training data. It should be noted that a flow meter is installed inside the oil pipeline 26, and the flow value of the liquid oil in the oil tank 23 is collected in real time through the flow meter.
[0080] Based on the historical training data set, the method of training a machine learning model for predicting the flow rate of liquid oil in the oil tank 23 is:
[0081] The feature data in each set of training data is used as the input of the machine learning model, and the flow value predicted by the machine learning model for the feature data is used as the output of the machine learning model. The flow value in the label data corresponding to each set of feature data is used as the prediction target, and the sum of all prediction accuracies is minimized as the training target. The calculation formula for prediction accuracy is αi=(Q 预 iQ 标 i) 2 , where αi is the prediction accuracy, Q 预 i is the predicted flow value corresponding to the i-th group of characteristic data, Q 标 i is the flow value in the i-th group of label data; the machine learning model is trained until the sum of the prediction accuracies reaches convergence and the training is stopped. The convergence standard is set by technical personnel in this field according to the specific model training situation.
[0082] The coil vertical winding device collects the winding speed and production data of the inner coil of the wind turbine stator 5 in real time. The production data includes the pressure data and temperature data of the liquid oil in the oil tank 23 .
[0083] The gravity variation curve of the wind turbine stator 5 is generated based on the winding speed of the inner coil of the wind turbine stator 5 .
[0084] The flow value of the liquid oil in the oil tank 23 is predicted based on the production data, the gravity variation curve and the machine learning model.
[0085] It should be noted that the above method can ensure that the weight of the lifting seat 24 is continuously increased during the process of the vertical winding mechanism 2 winding the coil on the inner side of the wind turbine stator 5, so that the lifting seat 24 and the wind turbine stator 5 are kept balanced. This can maximize the reduction of the load and energy consumption of the driving mechanism 25, reduce the cost of winding the wind turbine stator 5 coil, and increase the life of the driving mechanism 25, thereby reducing the maintenance cost of the vertical winding device of the high-power wind turbine module coil.
