Description

Technical Field

[0001] The utility model relates to the technical field of wind turbine training, in particular to a wind turbine centering teaching platform device. Background Art

[0002] In wind turbines, such as doubly-fed or semi-direct-drive generators, a gearbox needs to be added between the wind wheel and the generator to increase the speed. The gearbox and the generator are usually connected by an elastic coupling. The coaxiality between the output shaft of the gearbox and the rotating shaft of the generator is crucial to the stable operation of the entire equipment. Therefore, operators need to measure the coaxiality of the gearbox and the generator at regular intervals and make adjustments based on the measurement results.

[0003] Since the wind turbine cannot release the drive of the impeller end during the entire alignment process, and the wind speed during the transmission chain alignment process is unpredictable, improper operation will cause mechanical damage to the operator and may also cause damage to the alignment instruments and equipment. Therefore, for new employees, skilled employees are usually required to teach the process of generator alignment measurement. At present, the existing teaching method is to adopt on-site field teaching. During the on-site teaching process, the generator needs to be started and stopped at any time for practical adjustment. This teaching method is likely to cause loss of power generation. Moreover, due to the large torque generated by the wind wheel of the generator, if the wind speed is slightly higher, it will be impossible to align because the wheel cannot be turned. At this time, it is necessary to wait for the wind speed to decrease. The waiting process wastes time, and the trainees cannot fully operate, resulting in poor teaching effect.

[0004] Therefore, technicians have proposed an alignment teaching device, which models the components of the wind turbine so that operators can demonstrate the alignment process of the wind turbine without having to go to the site for operation. However, the existing alignment teaching device generally sets a start switch for the entire device, resulting in the entire device starting and stopping at the same time during the demonstration. This start switch makes the start and stop process not flexible enough, and it is not easy for trainees to understand the connection relationship and operation principle of the various components in the device.

[0041] The gear shaft 112 passes through the gear box 111 through two shaft through holes and extends out of the gear box 111. One end of the gear shaft 112 is connected to one end of the brake disc assembly 3, and the other end is connected to the brake device 2. The gear shaft 112 is a cylindrical structure with a cross-sectional diameter of 30 mm and a height of 700 mm, and is provided with an M30*100 thread at one end of the brake disc assembly 3.

[0042] Specifically, Figure 4As shown, the braking device 2 includes a fixing portion 21 and an adjusting portion 22 , the fixing portion 21 is connected to the adjusting portion 22 , the fixing portion 21 is installed on the outside of one end of the gear box 111 , and the adjusting portion 22 is connected to the other end of the gear shaft 112 for braking the gear shaft 112 .

[0043] In this embodiment, the fixing part 21 is connected to the adjusting part 22 through a connecting plate, the connecting plate is arranged horizontally, and the fixing part 21 is arranged vertically above one side of the connecting plate. At this time, the fixing part 21 is perpendicular to the connecting plate, and the adjusting part 22 is arranged vertically below the other side of the connecting plate. At this time, the connecting plate is perpendicular to the adjusting part 22. The entire brake device is made of iron material, with an overall height of 140 mm and a width of 50 mm. A fixing hole is arranged on the fixing part 21, and the aperture of the fixing hole is 11 mm. The screw passes through the fixing hole and the brake device mounting hole to fix the brake device on the outer side of the end cover of the gear box 111. The adjusting part 22 is provided with an axial hole 2211 with an aperture of 30.5 mm at the position corresponding to the shaft through hole. The other end of the gear shaft 112 passes through the shaft through hole and the axial hole 2211, and then the gear shaft 112 is braked by the adjusting part 22. In other embodiments, the brake device 2 can be replaced by a suitable L-shaped optical axis fixing clamp.

[0044] Specifically, Figure 4 As shown, the adjusting portion 22 includes an adjusting body 221 connected to the fixing portion 21 and an adjusting member 222. The adjusting body 221 is provided with an axial hole 2211 and an opening 2212. One end of the opening 2212 is connected to the axial hole 2211 and the other end is penetrated. The other end of the gear shaft 112 is penetrated in the axial hole 2211. The adjusting member 222 is connected to the adjusting body 221 and is used to adjust the opening degree of the opening 2212.

[0045] In this embodiment, the shaft hole 2211 is arranged in the middle area of ​​the adjusting body 221, the opening 2212 is arranged through the side of the adjusting body 221 away from the connecting plate, and is connected with the shaft hole 2211, the other end of the gear shaft 112 passes through the shaft through hole and the shaft hole 2211, and an adjusting member 222 is arranged on one side of the adjusting body 221, and the adjusting member 222 brakes the gear shaft 112 by adjusting the opening degree of the opening 2212.

[0046] Specifically, Figure 4 As shown, the adjusting member 222 includes connecting posts 2221 threadedly connected to two sides of the opening and twisting portions 2222 fixedly connected to the connecting posts 2221 , and the twisting portions 2222 are located outside the adjusting body 221 .

[0047] In this embodiment, with the opening 2212 as the boundary, a threaded hole is provided on one side of the adjustment body 221, and an adjustment through hole is provided on the other side. The connecting column 2221 is a threaded rod, and the threaded rod passes through the adjustment through hole and the threaded hole. The twisting part is located on the side close to the adjustment through hole. By rotating the twisting part 2222, the threaded rod is tightened in the threaded hole. In the process of rotating the twisting part 2222, the opening 2212 gradually shrinks, and the shaft hole 2211 also gradually shrinks, and the friction force on the gear shaft 112 gradually increases, thereby achieving a braking effect. In actual operation, the actual braking of the wind turbine is to brake the brake disc by clamping the hydraulic caliper fixed on the gear box. This embodiment is a teaching test platform, and no large torque is generated. Therefore, a mechanical braking device 2 is designed to brake the gear box 111. Among them, the twisting part 2222 is a butterfly nut.

[0048] Specifically, Figure 2-3 and Figure 5 As shown, the gearbox model 11 also includes: a first bearing assembly 113 and a second bearing assembly 114, the first bearing assembly 113 is arranged at one end of the gearbox 111, and the second bearing assembly 114 is arranged at the other end of the gearbox 111, and the adjustment part 22 and the outer side of one end of the gearbox 111 have an installation gap, and the first bearing assembly 113 is located in the installation gap.

[0049] In this embodiment, the first bearing assembly 113 and the second bearing assembly 114 both include a bearing and a bearing seat. Since the end cover is relatively thin, a bearing seat needs to be made. The bearing seat is a 400*400*20 iron block. The bearing seat is fixed to the end cover through the end cover mounting hole. A bearing through hole is provided in the middle area of ​​the bearing seat. The bearing is installed in the through hole. The first bearing assembly 113 is provided at one end of the gear box 111, and the second bearing assembly 114 is provided at the other end of the gear box 111, that is, at one end close to the brake disc assembly 3. Due to the setting of the overall structure of the brake device 2, there is an installation gap between the adjustment portion 22 and the outer side of the end cover, and the first bearing assembly 113 is located in the installation gap.

[0050] In the specific implementation, the gearbox assembly 1 also includes a gearbox base 12, the gearbox base 12 is placed on the teaching platform table 6, the gearbox model 11 is installed on the gearbox base 12, the gearbox base 12 has a size of 200*300*500mm, and is welded with square steel with a cross-sectional shape of 30*30*3mm.

[0051] Specifically, Figure 6 As shown, the coupling model 4 includes a spring clip 41, a spring clip fixing shaft 42, a flange 43 and a transmission shaft 44. The flange 43 is installed at both ends of the transmission shaft 44. The flange 43 and the spring clip 41 are connected through the spring clip fixing shaft 42. One end of one spring clip 41 is connected to the other end of the brake disc assembly 3, and one end of the other spring clip 41 is connected to the generator assembly 5.

[0052] In specific implementation, the spring clip 41 is used to transmit torque and absorb axial vibration, and is made of a steel sheet with a thickness of 3 mm; the spring clip fixing shaft 42 is a full-threaded screw of M16*90, and the distance between the spring clip 41 and the flange 43 can be adjusted by adjusting the fixing nut of the spring clip fixing shaft 42, thereby adjusting the horizontal installation position of the gearbox assembly 1 and the generator assembly 5; the flange 43 is made of PVC material and can be replaced by an integrated PVC flange with an inner diameter of 100 mm; in practice, the transmission shaft 44 and the flange 43 are interference fit, and there is a large friction force on the joint surface of the two. Under normal circumstances, the friction force can be used for transmission. When the generator assembly 5 is blocked or otherwise abnormally stuck, the transmission shaft 44 overcomes the friction force between the transmission shaft 44 and the flange 43 under the action of a large torque and rotates, thereby protecting the generator assembly from being damaged by large torque. This embodiment simulates this principle, and the transmission shaft 44 is replaced by a PVC water pipe with a model length of 190 mm and an outer diameter of 100 mm, and the transmission shaft 44 is fixed to the flange 43 using glue.

In order to enable the debugging feet 532 to stably support the generator model 52, it is preferably provided with a plurality of debugging feet 532, and arranged on the bottom plate 522. The debugging platform 531 horizontally sets a debugging part 533 corresponding to the position of each debugging foot 532. The debugging part 533 includes a debugging baffle and a debugging piece. The debugging baffle is vertically arranged on the edge of the debugging platform 531 and faces the debugging foot 532. The debugging baffle is provided with a debugging hole, and a thread is provided on the side of the debugging hole.
