Description

Technical Field

[0001] The invention relates to the field of wind turbine equipment training, and in particular to a wind turbine equipment training device. Background Art

[0002] As the most mature renewable energy generation besides hydropower, wind power generation accounts for the vast majority of the total installed capacity of renewable energy generation. Variable speed constant frequency wind turbine generator sets have become the mainstream model in wind power generation due to their high wind energy utilization rate. Since wind turbines are large equipment and are generally installed in high altitudes on towers with strong winds, installation and maintenance are very difficult, laborious and time-consuming.

[0003] Due to the vigorous development of wind power industry and the growth of installed capacity of wind turbines, the demand for wind turbine assembly and maintenance personnel has also increased accordingly. However, due to the limitations of on-site operations, both students majoring in wind power and maintenance personnel of enterprises only have theoretical knowledge of all the components of the entire wind turbine. The current assembly training platform only has the functions of assembly and debugging. There is currently no training platform for wind turbine assembly from parts assembly to component assembly to whole machine debugging.

[0004] According to the summary of wind farms, the most common faults of wind turbines are deformation of brake discs, mechanical or oil leakage faults of gearboxes. The current training platform does not provide relevant training on fault analysis and maintenance. As a result, the trainees cannot have a thorough understanding of the standard assembly methods required for component assembly from the maintenance perspective, and the standard assembly operations are not popularized to every assembly step. Therefore, the lack of knowledge on fault maintenance means that the training for beginners can only remain at the level of acceptance but inability to apply. Summary of the invention

DETAILED DESCRIPTION

[0029] like Figure 1 As shown, the present invention provides a wind turbine equipment training device, the wind turbine equipment training platform includes a simulation workbench, a wind turbine model arranged on the simulation workbench, a simulation wind device arranged on one side of the simulation workbench, an electrical control system arranged on the other side of the simulation workbench, and a human-computer interaction device arranged at the upper end of the simulation workbench; the electrical control system is electrically connected to the wind turbine model.

[0030] The wind turbine model to be assembled is fixed on the simulated workbench. First, the assembly video of the main components in the wind turbine model is explained through the human-computer interaction device. After the explanation, the trainees perform manual operations according to the training content and assemble the wind turbine model according to the methods in the training video. After the assembly is completed, a debugging experiment is carried out. The simulated wind device can demonstrate the variable pitch device of the wind wheel.

[0031] like Figure 2As shown, the simulation workbench includes a workbench frame 1, an assembly work platform 11, a transmission device 20 and a lifting workbench 30; the assembly work platform 11 is fixedly connected to the workbench frame 1, and a groove through hole is set on the assembly work platform. The number of the lifting work platforms 30 is the same as the number of components of the wind turbine model; the assembly work platform is an operating platform for the overall assembly of the wind turbine, and the entire test platform is on the same horizontal plane. After the trainees complete the wind turbine assembly training, the wind turbine model is disassembled and separated, and the transmission device 20 is fixed on the workbench frame 1 and is connected to the lifting workbench 30. When the main power of the transmission device 20 is started, the wind turbine model moves upward with the lifting workbench 30. Combined with the human-computer interaction system, the wind turbine model can be trained to disassemble and assemble separately. The point of this invention is that it can accommodate multiple trainees to conduct separate training on different models, so that the training platform can be more efficient.

[0032] The transmission device 20 includes a dual-output motor 201, a left first bevel gear 202, a left second bevel gear 203, a left screw 204, a left nut 205 and a left U-shaped frame 206 fixedly connected to the assembly work platform 11; the lifting workbench 30 also includes a right first bevel gear 207, a right second bevel gear 208, a right screw 209, a right nut 210, a right U-shaped frame 211 and a component workbench fixedly connected to the output shaft at the other end of the dual-output motor. The specific working process of the transmission device 20 is as follows: the dual-output motor 201 is fixedly connected to the lower plane of the workbench frame. After the dual-output motor 201 is started, the output shafts at both ends rotate simultaneously, which are the first output shaft and the second output shaft respectively. The key on the first output shaft is connected to the left first bevel gear 202, and the key on the second output shaft is connected to the right first bevel gear 207. The left first bevel gear 202 is meshed with the left second bevel gear 203 for transmission, and the right first bevel gear 207 is meshed with the right second bevel gear 208 for transmission. The key on the left first bevel gear 202 is connected to the left screw 204, and the right A bevel gear 207 is keyed to the right screw 209, driving the left screw 204 and the right screw 209 to rotate simultaneously. The left nut 205 is connected to the left screw 204 by transmission, and the left nut 205 is bolted to the left U-shaped frame 206; the right nut 210 is connected to the right screw 209 by transmission, and the right nut 210 is bolted to the right U-shaped frame 211. The left U-shaped frame 206 and the right U-shaped frame 211 are bolted to the component workbench. Through the transmission of the screw and the nut, the left U-shaped frame 206 and the right U-shaped frame 211 drive the component workbench to move upward. Double screw transmission is adopted to ensure that the component workbench is stable when it is lifted, and the horizontal degree of the component workbench can be ensured to have a small change. The number of transmission devices 20 is the same as the number of wind turbine models. Each transmission device 20 can independently control the lifting and lowering action of the lifting platform 30. The transmission devices 20 can also be controlled to start or shut down at the same time through an electrical control system. The lifting platforms 30 raised at the same time can accommodate multiple people to conduct training courses on different wind turbines. When conducting overall system teaching and training for a single person or a single group of students, the lifting platforms 30 can be controlled to rise and fall one by one according to the teaching sequence to meet the requirements of different teaching cases.

[0033] like Figure 3 , 4 As shown in Figure 5, the component workbench (equivalent to the lifting workbench 30) includes a cylinder bracket 302 fixedly connected to the main workbench 301, a two-way cylinder 303 fixedly connected to the cylinder bracket 302, a first telescopic mechanism fixedly connected to the first piston rod 304 of the two-way cylinder 303, a second telescopic mechanism fixedly connected to the second piston rod 307 of the two-way cylinder, a tool table 308 fixedly connected to the second telescopic mechanism, and a part table 309 fixedly connected to the first telescopic mechanism.

[0034] To explain more clearly, Figure 4 The first telescopic mechanism includes a left first connecting rod 3051, a left second connecting rod 3052, a left third connecting rod 3053, a left fourth connecting rod 3054, a left fifth connecting rod 3055, a left sixth connecting rod 3056, a left first shaft sleeve 3060, a left second shaft sleeve 3061 and a left optical axis 3062; the first telescopic mechanism also includes a left first pin shaft 3057, a left second pin shaft 3058 and a left third pin shaft 3059.

[0035] One end of the left first connecting rod 2051 is rotatably connected to the first piston rod 304, and the other end of the left first connecting rod 3051 is rotatably connected to the left third connecting rod 3053; one end of the left second connecting rod 3052 is rotatably connected to the first piston rod 304, and the other end of the left second connecting rod 3052 is rotatably connected to the left fourth connecting rod 3054; the center of the left third connecting rod 3053 is rotatably connected to the center of the left fourth connecting rod 3054; the left fifth connecting rod 3055 is rotatably connected to the left third connecting rod 3053 and away from the left first connecting rod 3051, and the left sixth connecting rod is rotatably connected to the left fourth connecting rod 3054 and away from the left second connecting rod 3052. The left first pin shaft 3057 is rotatably connected to the left first connecting rod 3051, the left second connecting rod 3052 and the hinge of the first piston rod 304. The left second pin shaft 3061 is rotatably connected to the hinge of the left third connecting rod 3053 and the left fourth connecting rod 3054, and the left third pin shaft 3059 is rotatably connected to the hinge of the left fifth connecting rod 3055 and the left sixth connecting rod 3056. The left second pin shaft 3058 is bolted to the left first shaft sleeve 3060, and the left third pin shaft 3059 is bolted to the left second shaft sleeve 3061. The left optical axis 3062 is fixedly connected to the cylinder bracket 302, the left first shaft sleeve 3060 and the left second shaft sleeve 3061 are linear shaft sleeves, and their inner holes slide on the left optical axis 3062, and the tool table 309 is bolted to the left second shaft sleeve 3061. The second telescopic mechanism has the same structure as the first telescopic mechanism.

[0036] The second telescopic mechanism includes a right first connecting rod, a right second connecting rod, a right third connecting rod, a right fourth connecting rod, a right fifth connecting rod, a right sixth connecting rod, a right first pin, a right second pin, a right third pin, a right first sleeve, a right second sleeve and a right optical axis; one end of the right first connecting rod is rotatably connected to the second piston rod 307, and the other end of the right first connecting rod is rotatably connected to the right third connecting rod; one end of the right second connecting rod is rotatably connected to the right first piston rod, and the other end of the right second connecting rod is rotatably connected to the right fourth connecting rod; the center of the right third connecting rod is rotatably connected to the center of the right fourth connecting rod; the right fifth connecting rod is rotatably connected to the right third connecting rod and is away from the right first connecting rod, and the right sixth connecting rod is rotatably connected to the right fourth connecting rod and is away from the right second connecting rod. The right first pin is rotatably connected to the right first connecting rod, the right second connecting rod and the hinge of the second piston rod 307. The right second pin is rotatably connected to the hinge of the right third connecting rod and the right fourth connecting rod, and the right third pin is rotatably connected to the hinge of the right fifth connecting rod and the right sixth connecting rod. The right second pin is bolted to the right first sleeve, and the right third pin is bolted to the right second sleeve. The right optical axis is fixedly connected to the bracket, and the right first sleeve and the right second sleeve are linear sleeves, whose inner holes slide on the right optical axis, and the parts table 308 is bolted to the right second sleeve.

[0037] When the lifting table 30 is raised, the dual output motor 201 stops, the first piston rod 304 and the second piston rod 307 of the bidirectional cylinder 303 extend simultaneously, the left first connecting rod 3051, the left second connecting rod 3052, the left third connecting rod 3053, the left fourth connecting rod 3054, the left fifth connecting rod 3055, and the left sixth connecting rod 3056 are cross-connected structures, and the first pin 3057, the second pin 3058, and the third pin 3059 are simultaneously pushed away from the cylinder, and drive the part table 309 fixedly connected to the left second shaft sleeve 3061 to be pushed away from the cylinder. At the same time, the second telescopic mechanism pushes the tool table 308 away from the cylinder by the same distance. At this time, the trainees can carry out training and learning of the corresponding model, disassemble individual parts, and combine the training courseware of the human-computer interaction device to enable the trainees to combine theory with practice in the internal structure and repair and maintenance knowledge of the model. The disassembled parts can be placed on the extended parts table 309, which is not easy to lose or damage the model; the tools needed for this model are placed on the tool table 308, so that there is no need to find tools during the learning process, which improves learning efficiency. The adoption of this telescopic mechanism is because the telescopic mechanism set under the lifting workbench 30 is not suitable for using a cylinder with a too large stroke. The telescopic mechanism adopts a cross-structured connecting rod transmission, and a shorter stroke cylinder can be used, so that the stroke output is larger.

[0038] like Figure 1 , 6As shown, the wind turbine model includes a wind rotor, a gearbox, a main shaft, a generator, a machine base, a yaw mechanism and a wind turbine shield. The wind rotor is fixedly connected to the machine base, and a yaw mechanism is connected under the machine base. The wind rotor is connected to the input shaft end of the gearbox through a main shaft; the output shaft of the gearbox is connected to the output shaft of the generator; the wind turbine shield is arranged on the wind rotor, gearbox, main shaft and the outer part of the motor; the yaw mechanism is fixedly connected to the lower end of the wind turbine shield; the wind rotor, gearbox and generator are all provided with a cutaway shield with the same shape as the real object. This model is a reduced model of the real object, and its internal structure is the same as the existing real object. The wind rotor model is provided with a pitch device; the gearbox model adopts a planetary and parallel shaft hybrid transmission structure, and the wind turbine model adopts a brushed double-fed generator. The cutaway shield is set so that the internal structure of the model can be seen.

[0039] like Figure 7 , 8 As shown, the wind simulation device of the wind turbine set also includes a support platform 401, an arc support plate 402 rollingly connected to the support platform 401, a blower 403 fixedly connected to the arc support plate 402, an air duct 404 fixedly connected to the air outlet of the blower 403, and a spherical sleeve 405 fixedly connected to the air outlet of the air duct 404; the wind simulation device is arranged opposite to the wind wheel. The wind simulation device of the wind turbine set also includes an elliptical gear 406 meshingly connected to the arc support plate 402, a transmission shaft 407 fixedly connected to the elliptical gear 406, a second motor 408 whose output shaft is fixedly connected to the transmission shaft 407, and a plane bearing 409 arranged between the upper end surface of the support platform 401 and the lower end surface of the arc support plate 402; the second motor 408 is fixedly connected to the support platform 401.

[0040] The radius of the elliptical gear 406 changes with rotation, and the arc tooth radius of the arc support plate 402 changes with the change of the radius of the elliptical gear 406. During operation, the distance between the operating axis of the arc support plate 402 and the axis of the elliptical gear 406 remains unchanged.

[0041] The specific working process is as follows: the second motor 408 rotates, the transmission shaft 407 key-connected to the second motor 408 rotates, the elliptical gear 406 fixedly connected to the transmission shaft 407 rotates, and the elliptical gear 406 is transmission-connected to the arc support plate 402, so that the blower 403 bolted to the arc support plate 402 slides on the upper surface of the support platform 401. In order to reduce friction, a plane bearing 409 is added between the arc support plate 402 and the support platform 401, and a spherical sleeve 405 is provided at the air outlet of the air duct 404. The inner hole of the spherical sleeve 405 The blower 403 is fixedly connected to the air duct 404, and has a frequency conversion function, which can control the size of the air outlet. After the second motor 408 is started, the elliptical gear 406 rotates, driving the arc support plate 402 meshing therewith to rotate around the relative wind wheel. A shaft sleeve bracket 411 bolted to the support platform 401 is provided at the protruding end of the air duct 404, and a spherical groove is provided on the shaft sleeve bracket 411. Since a spherical sleeve 405 is provided at the outlet of the air duct 404, the outer circle of the spherical sleeve 405 is spherical, and relative sliding occurs with the inner hole of the shaft sleeve bracket 411. In order to reduce the weight of the air duct 404, the air duct 404 is a 0.1 mm aluminum foil hose. The blower 403 can output wind at different speeds. When the wind speed is switched, the spherical sleeve 405 is made to swing in the shaft sleeve bracket 411. The greater the wind speed difference, the greater the swing. At this time, the wind direction of the air outlet of the air duct 404 changes with the spherical sleeve 405, which approximately simulates natural wind. The second motor 408 switches forward and reverse when working. The switching time of the second motor 408 is controlled according to the stroke of the arc support plate 402. The setting of the simulated wind device is to train and explain the movement of the variable pitch device that occurs during the operation of the wind wheel, so that the training of the variable pitch device is closer to actual work.

[0042] The human-machine interaction device includes a media display screen fixedly connected to the upper end of the assembly work platform 11, an audio device fixedly connected to the upper end of the assembly work platform 11, a host connected to the media display screen and the audio device, and a button fixedly connected to the lower end of the test platform; the button controls the dual-output motor 201, the bidirectional cylinder 303, and the second motor 408. The media display screen is connected to the host.

[0043] The present invention can also be provided with a hydraulic system on the simulation workbench; the hydraulic system includes a hydraulic station, a control system, and an actuator.

[0044] The teaching and training platform of the present invention combines training contents such as on-site simulated assembly videos, disassembly and assembly of model components videos, circuit wiring and debugging videos, hydraulic system piping layout videos, and fault analysis training courseware with manual operation, which has a strong and intuitive training effect on learning and maintenance personnel in the wind power generation industry.

[0045] In addition, there are still details that need to be improved in the wind simulation device of the present invention. Since this device is not a test platform, the wind simulation device is only for the training of the variable pitch device. Further improvements can be made in other test platforms.
