Description

Technical Field

[0001] The invention relates to the field of wind generator set coupling safety protection equipment, in particular to a wind generator set coupling slippage fault detection device. Background Art

[0002] When the wind turbine generator set is working normally, the shafts on both sides of the coupling will keep rotating, and the rotation of the shafts is synchronous. Therefore, the coupling of the wind turbine generator set is an important component for transmitting torque between the speed increaser and the generator. When the torque fluctuates greatly, the coupling torque limiter will slip to protect the speed increaser and generator on the transmission chain from damage caused by impact loads; at the same time, when the accumulated slip angle exceeds a certain angle, the coupling torque limiter will wear out, resulting in a decrease in torque transmission performance, and thus unable to continuously transmit torque, and needs to be replaced in time.

[0003] However, the slippage failure of the coupling cannot be effectively detected through observation. However, for the safe operation of the wind turbine, the slippage failure of the coupling needs to be fed back in time. Therefore, how to detect the slippage failure of the coupling has become an urgent problem to be solved in the field of wind turbine coupling safety equipment. Summary of the invention

[0004] The purpose of the present invention is to overcome the problem in the prior art that when a coupling slips, it can only be discovered through data fluctuation calculations due to the inability to observe, resulting in the inability to provide timely feedback on the slip, which increases the safety risk of the wind turbine generator set. The present invention provides a wind turbine generator set coupling slip detection device, which effectively feeds back the coupling slip by utilizing the phenomenon that there is a speed difference in the rotation speed of the shafts on both sides of the coupling when a slip occurs, thereby ensuring the safety of the wind turbine generator set coupling.

[0005] The purpose of the present invention is mainly achieved through the following technical solutions: The invention discloses a coupling slip fault detection device for a wind turbine generator set, comprising a collar gear, wherein the collar gear is sleeved on the shaft bodies on both sides of the coupling, and the collar gear is fixed to the shaft body. It also includes a bearing base, the bearing base is located below the coupling, a first transmission support assembly and a second transmission support assembly are fixed on the bearing base, and a slip feedback assembly is provided between the first transmission support assembly and the second transmission support assembly; The first transmission support assembly and the second transmission support assembly have the same structure; The first transmission supporting assembly is located under one of the shafts, the second transmission supporting assembly is located under the other shaft, and the slip feedback assembly is connected to the first transmission supporting assembly and the second transmission supporting assembly respectively: when there is a speed difference between the rotation of the shaft on the first transmission supporting assembly and the rotation of the shaft on the second transmission supporting assembly, the slip feedback assembly sends out an alarm.

[0006] At present, during the operation of a wind turbine, a coupling is used to connect the shafts on both sides and transmit the power. The shafts on both sides of the coupling will rotate. During normal operation, the rotation speeds of the shafts on both sides of the coupling are basically the same. At this time, the coupling can effectively transmit torque. If the coupling slips, it means that there is a difference in the rotation speeds of the shafts on both sides of the coupling. At this time, the torque transmission is interrupted, so the coupling will be damaged, and the normal operation of the wind turbine will be seriously affected.

[0007] The existing technology mainly relies on the abnormal fluctuation of third-party data, such as the abnormal fluctuation of power generation data, to find out whether the coupling position is slipping. The existing technology is inefficient and has the risk of wrong detection, which leads to the problem of expanding damage.

[0008] In the present invention, by sleeve-arranging and fixing the collar gear on the shafts at both sides of the coupling, the rotation of the shaft is fed back to the first transmission support assembly and the second transmission support assembly through the collar gear, and the rotation speeds received by the first transmission support assembly and the second transmission support assembly can be effectively unified by unifying the outer diameter specifications of the collar gear, so that the first transmission support assembly and the second transmission support assembly can effectively transmit the actual shaft rotation speed to the slip feedback assembly; The two sides of the slip feedback component can receive the shaft rotation speed on both sides of the coupling. When the rotation speed of the two shafts is normal, there is no speed difference between the first transmission support component and the second transmission support component at the slip feedback component. At this time, the slip feedback component does not alarm. When there is a difference in the rotation speed of the two shafts, it proves that at the coupling position, there is a speed difference in the shaft rotation on both sides of the coupling. At this time, the coupling cannot effectively transmit torque, slippage occurs, and the slip feedback component issues an alarm.

[0009] According to the present invention, when slippage occurs, the shafts on both sides of the coupling will have a rotational speed difference. The differential speed of the shafts can be effectively collected by the first transmission support assembly and the second transmission support assembly, and the slippage can be effectively alerted to the staff through an alarm through the slippage feedback assembly, so that the staff can effectively deal with the slippage problem in real time to avoid more serious damage.

[0010] Further, the slip feedback assembly includes a first transmission shaft and a second transmission shaft, the first transmission shaft is connected to the first transmission support assembly, and the second transmission shaft is connected to the second transmission support assembly: the rotation of the shaft on the first transmission support assembly can drive the first transmission shaft to rotate, and the rotation of the shaft on the second transmission support assembly can drive the second transmission shaft to rotate; A differential feedback assembly is provided between the first transmission shaft and the second transmission shaft, and a differential alarm assembly is provided on the differential feedback assembly. When there is a speed difference between the rotation of the first transmission shaft and the rotation of the second transmission shaft, the differential alarm assembly sends out an alarm.

[0011] In the present invention, the first transmission shaft is used to connect the first transmission support assembly, and the first transmission support assembly can transmit the rotation of the collar gear to the first transmission shaft, so as to effectively feedback the rotation state of the shaft body on the first transmission support assembly. Similarly, the second transmission support assembly can also transmit the rotation state of the shaft body on the other side to the second transmission shaft; The first transmission shaft and the second transmission shaft are both connected to the differential feedback assembly, and the differential feedback assembly is used to issue an alarm when there is a speed difference between the first transmission shaft and the second transmission shaft.

[0012] Further, the differential alarm assembly includes a first sun gear and a second sun gear, the first sun gear is fixed to the first transmission shaft, the second sun gear is fixed to the second transmission shaft, and the axes of the first sun gear and the second sun gear coincide with each other; The first transmission shaft is sleeved with a first sleeve and a side rotating disk, the first sleeve is fixed to the side rotating disk, the side rotating disk is provided with a first connecting plate and a second connecting plate, the first connecting plate and the second connecting plate are symmetrical with respect to the axis of the first sun gear; The first connecting plate is rotatably connected with a first planetary gear, the second connecting plate is rotatably connected with a second planetary gear, and the first planetary gear and the second planetary gear are both meshed with the first sun gear and the second sun gear.

[0013] In the present invention, the first sun gear is connected to the first transmission shaft, and the second sun gear is connected to the second transmission shaft. When the rotation speed of the first transmission shaft is the same as the rotation speed of the second transmission shaft, the shaft bodies on both sides of the coupling rotate synchronously. At this time, the first sun gear and the second sun gear can drive the meshing first planetary gear and the second planetary gear to rotate circumferentially around the axis of the first sun gear. Since there is no differential speed at this time, the first planetary gear and the second planetary gear will not rotate on their own. The first connecting plate provides a supporting base for the first planetary gear, the second connecting plate provides a supporting base for the second planetary gear, the side rotating disk is used to carry the first connecting plate and the second connecting plate, so that the circumferential rotation of the first planetary gear and the second planetary gear around the axis of the first sun gear can be synchronized, and the first sleeve is used to limit the side rotating disk and assist the free rotation of the side rotating disk on the first transmission shaft; When there is a speed difference between the shafts on both sides of the coupling, the first planetary gear and / or the second planetary gear will continue to rotate synchronously around the axis of the first sun gear under the restriction of the first connecting plate and the second connecting plate. Since the first transmission shaft and the second transmission shaft will simultaneously follow the shafts to have a speed difference, there will be a speed difference between the first sun gear and the second sun gear. Therefore, the first planetary gear and the second planetary gear will absorb the speed difference between the first sun gear and the second sun gear by self-rotation, thereby not affecting the rotation of the first transmission shaft and the second transmission shaft. When the first planetary gear and / or the second planetary gear starts to rotate, it indicates that the coupling is slipping, and the differential alarm component sounds an alarm.

[0014] Furthermore, a second sleeve is sleeved on the second transmission shaft, a first connecting rod and a second connecting rod are fixed on the second sleeve, the first connecting rod extends and is fixed to the first connecting plate, and the second connecting rod extends and is fixed to the second connecting plate.

[0015] In the present invention, the second sleeve sleeved on the second transmission shaft can rotate freely on the second transmission shaft, so that the first planetary gear and the second planetary gear can be synchronized without restricting the rotation of the second transmission shaft, and can provide sufficient basic load for the first planetary gear and the second planetary gear, so that the meshing of the first planetary gear, the second planetary gear and the first sun gear and the second sun gear will not be stuck, so that the speed difference between the first transmission shaft and the second transmission shaft is only reflected in the rotation speed of the first planetary gear and the second planetary gear. The faster the rotation speed of the first planetary gear and the second planetary gear is, the greater the rotation speed difference between the first transmission shaft and the second transmission shaft is, which means that the slippage of the coupling is more serious.

[0016] Furthermore, a first rotation alarm component is provided on the first connecting plate, and the first planetary gear is rotationally connected to the first rotation alarm component: when the first planetary gear rotates, the first rotation alarm component sends out an alarm; The second connecting plate is provided with a second rotation alarm component, and the second planetary gear is rotationally connected to the second rotation alarm component: when the second planetary gear rotates, the second rotation alarm component sends out an alarm; The first rotation alarm component and the second rotation alarm component have the same structure.

[0017] In the present invention, the first rotation alarm component is used to detect whether the first planetary gear and the second planetary gear rotate. If the first planetary gear and / or the second planetary gear rotates, the first rotation alarm component is controlled to sound an alarm.

[0018] Furthermore, the first rotation alarm component includes a component housing, a rotation rod is fixed on the first planetary gear, and the rotation rod passes through the first connecting plate and extends into the component housing; A plurality of sound generating chambers are provided in the housing of the component, and the sound generating chambers are distributed circumferentially around the rotating rod; The sound-generating chamber comprises a resonance cavity, a notch is provided on a side of the resonance cavity facing the rotating rod, and a string body is fixed at the notch; A plectrum is fixed on the rotating rod, and the plectrum is used to pluck the string body.

[0019] In the present invention, the rotating rod is used to transmit the rotation of the first planetary gear to the component housing, and the resonance cavity in the sound-generating chamber can emit sound through resonance when the string body is vibrated. At this time, if the first planetary gear rotates, the rotating rod controls the plectrum to pluck the string body, and the string body vibrates to generate sound, so that the sound-generating chamber emits an alarm sound; In the present invention, a plurality of sound generating chambers are arranged circumferentially around the rotating rod, so that the frequency of the sound is positively correlated with the rotation speed of the rotating rod. Therefore, when slippage occurs, the severity can be determined according to the speed of plucking the string. The vibration frequency of the plucking string can be changed by means of existing technologies such as material screening and resonance cavity shaping, so as to avoid affecting the wind turbine generator set and avoid the mechanical vibration frequency of the wind turbine generator set, thereby enhancing the recognizability of the plucking sound and enhancing the warning effect of the alarm.

[0020] Furthermore, the first transmission support assembly includes a support shell, and an arc-shaped groove is provided on the top of the support shell, and the arc-shaped groove can partially accommodate the collar gear; A rotating gear is provided in the supporting shell, and the top of the rotating gear passes through the supporting shell and meshes with the collar gear; The end face of the rotating gear facing away from the slip feedback assembly is connected with an end bearing, a support is fixed at the bottom of the end bearing, the support extends and is fixed into the bearing base, and the other end face of the rotating gear is connected with the slip feedback assembly.

[0021] In the present invention, the supporting shell in the first supporting assembly is used to protect the internal structure, and the arc-shaped groove is used to accommodate the ring gear. The rotation of the shaft is transmitted to the first transmission shaft through the engagement of the ring gear and the rotating gear. Through the load-bearing of the end bearing, the pillar can support the first transmission shaft and the first transmission shaft can also rotate freely and effectively.

[0022] Furthermore, a plurality of oblique support rods are provided on the side of the end bearing, one end of the oblique support rod is fixed to the supporting shell, and the other end thereof is fixed with a connecting end, and the connecting end is hinged to the end bearing; An elastic support is arranged between the connecting ends, the connecting ends are fixed to the elastic support, and the elastic support is fitted to the end bearing.

[0023] In the present invention, the side surface of the end bearing is stabilized by a plurality of oblique support rods, so that the first transmission shaft can rotate more stably, and the elastic support is used to play a safety role. When the support of the end bearing by the pillar is unstable, the end bearing can be effectively prevented from falling by the hinged oblique support rods and the elastic support between the oblique support rods. Therefore, in the event of collapse of the pillar, the structural safety of the first transmission shaft can still be guaranteed, thereby enhancing the overall safety of the present invention.

[0024] Furthermore, a rotation gap is left between the arc-shaped groove and the collar gear: the collar gear can rotate freely, and when the collar gear rotates, it can drive the rotating gear to rotate.

[0025] In the present invention, the rotational clearance between the arc groove and the collar gear is used to prevent the rotation of the collar gear or the rotating gear from being affected, thereby ensuring the normal meshing of the rotating gear and the collar gear. The normal support of the shaft body and the coupling in the present invention is an existing technology, so it is easy to control the rotational clearance between the collar gear and the arc groove on this basis.

[0026] Furthermore, the bearing base includes a plurality of elastic filling layers, and the elastic filling layers fill the bearing base; The elastic filling layer includes a first filling block and a second filling block. The elastic expansion and contraction direction of the first filling block is perpendicular to the elastic expansion and contraction direction of the second filling block. The first filling block and the second filling block are staggered.

[0027] In the present invention, the elastic filling layer in the bearing base is perpendicular to the first filling block and the second filling block, so that the force on the elastic filling layer is more uniform. When it is pressed by a large weight, it can also effectively prevent the pressed object from rolling, thereby effectively enhancing the bearing capacity of the bearing base in the present invention.

[0028] The first filling block and the second filling block are staggered in distribution: the elastic fillings adjacent to the first filling block in each direction are preferentially set to the second filling block, and the elastic fillings adjacent to the second filling block in each direction are preferentially set to the first filling block, so that the elastic expansion and contraction directions of the first filling block and the second filling block can complement each other, thereby achieving the purpose of enhancing the bearing capacity of the bearing base.

[0029] In summary, the present invention has the following beneficial effects compared with the prior art: In the present invention, both sides of the slip feedback component can receive the shaft rotation speeds on both sides of the coupling. When the rotation speeds of the two shafts are normal, there is no speed difference between the first transmission support component and the second transmission support component at the slip feedback component. At this time, the slip feedback component does not alarm. When there is a difference in the rotation speeds of the two shafts, it proves that at the coupling position, there is a speed difference in the shaft rotation on both sides of the coupling. At this time, the coupling cannot effectively transmit torque, slippage occurs, and the slip feedback component issues an alarm. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention. Example

[0032] like Figure 1~Figure 4 As shown, this embodiment relates to a wind turbine coupling slip fault detection device, comprising a collar gear 2, the collar gear 2 is sleeved on the shaft body 1 on both sides of the coupling 3, and the collar gear 2 is fixed to the shaft body 1. It also includes a bearing base 6, the bearing base 6 is located below the coupling 3, a first transmission support assembly 4 and a second transmission support assembly 7 are fixed on the bearing base 6, and a slip feedback assembly 5 is provided between the first transmission support assembly 4 and the second transmission support assembly 7; The first transmission support assembly 4 and the second transmission support assembly have the same structure; The first transmission supporting assembly 4 is located under one of the shaft bodies 1, the second transmission supporting assembly 7 is located under the other shaft body 1, and the slip feedback assembly 5 is respectively connected to the first transmission supporting assembly 4 and the second transmission supporting assembly: when there is a speed difference between the rotation of the shaft body 1 on the first transmission supporting assembly 4 and the rotation of the shaft body 1 on the second transmission supporting assembly, the slip feedback assembly 5 issues an alarm.

[0033] In the actual application of this embodiment, the bearing base 6 is used to bear the overall weight of this embodiment. When the coupling 3 starts to work normally, the shaft bodies 1 on both sides of the coupling 3 rotate normally, and the shaft bodies 1 and the coupling 3 work normally based on the existing technology. This embodiment detects and alarms the slippage fault of the coupling 3 based on the normal operation of the coupling 3 and the shaft body 1.

[0034] The first transmission support assembly 4 is used to detect the rotation speed of one of the shaft bodies 1, and the second transmission support assembly 7 is used to detect the rotation speed of the other shaft body 1. When the rotation speeds of the shaft bodies 1 on both sides of the coupling 3 are stable, there is no speed difference, so that the slip feedback assembly 5 is in a stable state, and no alarm is issued at this time; When the rotation speed of the shaft 1 on both sides of the coupling 3 changes suddenly, it means that the torque transmission between the shafts 1 fails, proving that the coupling 3 is slipping. At this time, there is a speed difference between the rotation speeds of the shaft 1 received by the first transmission support component 4 and the second transmission support component 7. The larger the speed difference, the more serious the slip fault. At this time, the slip feedback component 5 sounds an alarm.

[0035] In this embodiment, the first transmission support component 4 and the second transmission support component 7 detect the rotation speed of the shaft bodies 1 on both sides of the coupling 3, so as to effectively display the rotation speed difference of the shaft bodies 1 on both sides of the coupling 3 to the slip feedback component 5. The slip feedback component 5 can determine whether the position of the coupling 3 is slipping based on the speed difference, so as to provide timely processing measures to avoid the deterioration of the slip fault.

[0036] Further, the slip feedback assembly 5 includes a first transmission shaft 51 and a second transmission shaft 515, the first transmission shaft 51 is connected to the first transmission support assembly 4, and the second transmission shaft 515 is connected to the second transmission support assembly 7: the rotation of the shaft body 1 on the first transmission support assembly 4 can drive the first transmission shaft 51 to rotate, and the rotation of the shaft body 1 on the second transmission support assembly 7 can drive the second transmission shaft 515 to rotate; A differential feedback assembly is provided between the first transmission shaft 51 and the second transmission shaft 515, and a differential alarm assembly is provided on the differential feedback assembly. When there is a speed difference between the rotation of the first transmission shaft 51 and the rotation of the second transmission shaft 515, the differential alarm assembly sounds an alarm.

[0037] In this embodiment, the first transmission shaft 51 and the second transmission shaft 515 are used to transmit the rotation of the two shaft bodies 1 to the rotation of the first transmission shaft 51 and the rotation of the second transmission shaft 515 through the ring gear 2, so that the speed difference between the two shaft bodies 1 can be effectively converted into the speed difference between the first transmission shaft 51 and the second transmission shaft 515, and then the rotation speed difference between the first transmission shaft 51 and the second transmission shaft 515 is effectively fed back through the differential feedback component. When there is a differential situation, an alarm can be issued through the differential alarm component to warn of the slippage phenomenon.

[0038] Further, the differential alarm assembly includes a first sun gear 53 and a second sun gear, the first sun gear 53 is fixed to the first transmission shaft 51, the second sun gear is fixed to the second transmission shaft 515, and the axes of the first sun gear 53 and the second sun gear coincide with each other; The first transmission shaft 51 is sleeved with a first sleeve 522 and a side rotating disk 521, the first sleeve 522 is fixed to the side rotating disk 521, the side rotating disk 521 is provided with a first connecting plate 55 and a second connecting plate 510, the first connecting plate 55 and the second connecting plate 510 are symmetrical with respect to the axis of the first sun gear 53; The first connecting plate 55 is rotatably connected to the first planetary gear 54 , and the second connecting plate 510 is rotatably connected to the second planetary gear 58 . The first planetary gear 54 and the second planetary gear 58 are both meshed with the first sun gear 53 and the second sun gear.

[0039] In this embodiment, the rotation of the collar gear 2 can effectively drive the first transmission shaft 51 and the second transmission shaft 515 to rotate through the meshing relationship. When the first transmission shaft 51 rotates, it will drive the first sun gear 53 to rotate. When the second transmission shaft 515 rotates, it will drive the second sun gear to rotate. In addition, due to the meshing relationship between the first planetary gear 54 and the second planetary gear 58 and the first sun gear 53 and the second sun gear, when the first sun gear 53 and the second sun gear rotate, the first planetary gear 54 and the second planetary gear 58 will be driven to rotate circumferentially around the axis of the first sun gear 53. At this time, if the rotation speeds of the first transmission shaft 51 and the second transmission shaft 515 are the same, that is, no slippage occurs, then the first planetary gear 54 and the second planetary gear 58 will not rotate. When a speed difference occurs between the first transmission shaft 51 and the second transmission shaft 515, that is, the coupling 3 slips, the first planetary gear 54 and the second planetary gear 58 can balance the speed difference by self-rotation, so that the first planetary gear 54 and the second planetary gear 58 can rotate circumferentially around the axis of the first sun gear 53 and avoid getting stuck during the rotation process by self-rotation.

[0040] In this embodiment, a corresponding alarm device is arranged on the differential alarm component. When the first planetary gear 54 and the second planetary gear 58 rotate, slippage occurs. When the coupling 3 slips, the slippage fault has different degrees of severity. When the slippage first occurs, the rotation speed difference of the shaft 1 on both sides of the coupling 3 has not yet widened. At this time, there is a speed difference between the first transmission shaft 51 and the second transmission shaft 515, but the speed difference is not large, so the alarm level issued by the differential alarm component can be relatively low. If the speed difference becomes larger, the alarm level can be increased, thereby effectively distinguishing the severity of the slippage fault and achieving the purpose of selecting corresponding countermeasures.

[0041] Furthermore, a second sleeve 513 is sleeved on the second transmission shaft 515 , and a first connecting rod 514 and a second connecting rod 512 are fixed to the second sleeve 513 . The first connecting rod 514 extends and is fixed to the first connecting plate 55 , and the second connecting rod 512 extends and is fixed to the second connecting plate 510 .

[0042] In this embodiment, the second sleeve 513 sleeved on the second transmission shaft 515 can rotate freely on the second transmission shaft 515. Through the connection between the first connecting rod 514 and the second connecting rod 512, the rotation of the second sleeve 513 and the rotation of the side rotating disk 521 can be effectively synchronized, thereby improving the integrity of the side rotating disk 521, the first planetary gear 54 and the second planetary gear 58 when rotating around the axis of the first sun gear 53, thereby achieving the purpose of providing a support base for the first planetary gear 54 and the second planetary gear 58.

[0043] The first connecting plate 55 and the second connecting plate 510 can effectively complete the mounting of the first planetary gear 54 and the second planetary gear 58 .

[0044] Furthermore, a first rotation alarm component 57 is provided on the first connecting plate 55, and the first planetary gear 54 is rotationally connected to the first rotation alarm component 57: when the first planetary gear 54 rotates, the first rotation alarm component 57 sends out an alarm; The second connecting plate 510 is provided with a second rotation alarm component 511, and the second planetary gear 58 is rotationally connected to the second rotation alarm component 511: when the second planetary gear 58 rotates, the second rotation alarm component 511 sends out an alarm; The first rotation alarm component 57 and the second rotation alarm component 511 have the same structure.

[0045] The first connecting plate 55 and the first planetary gear 54 are connected via a first intermediate bearing 56, so as to support the first planetary gear 54 to generate self-rotation on the basis of being mounted on the first connecting plate 55; The second connecting plate 510 and the second planetary gear 58 are connected via a second intermediate bearing 59 , so as to support the second planetary gear 58 to generate self-rotation based on being mounted on the second connecting plate 510 .

[0046] In this embodiment, the first rotating alarm component 57 is located on the first connecting plate 55, and the second rotating alarm component 511 is located on the second connecting plate 510, so that the first connecting plate 55 and the second connecting plate 510 can serve the purpose of carrying the first rotating alarm component and the second rotating alarm component 511.

[0047] Since the rotation of the first planetary gear 54 and the second planetary gear 58 can provide feedback on whether there is a speed difference problem, in this embodiment, the first rotation alarm component 57 monitors the rotation of the first planetary gear 54, and the second rotation alarm component 511 monitors the rotation of the second planetary gear 58. When the first planetary gear 54 rotates, the first rotation alarm component 57 issues an alarm, and when the second planetary gear 58 rotates, the second rotation alarm component 511 issues an alarm, so that the alarm processing of the slipping phenomenon can be achieved through the first rotation alarm component 57 and the second rotation alarm component 511.

[0048] Furthermore, the first rotation alarm component 57 includes a component housing 571, and a rotation rod 576 is fixed on the first planetary gear 54, and the rotation rod 576 passes through the first connecting plate 55 and extends into the component housing 571; A plurality of sound chambers 574 are provided in the component housing 571, and the sound chambers 574 are circumferentially distributed around the rotating rod 576; The sound chamber 574 includes a resonance cavity 575 , and a notch 573 is provided on one side of the resonance cavity 575 facing the rotating rod 576 , and a string body 572 is fixed to the notch 573 ; A plectrum 577 is fixed on the rotating rod 576 , and the plectrum 577 is used to pluck the string body 572 .

[0049] In this embodiment, the first rotation alarm component 57 extends the rotation of the first planetary gear 54 to the component housing 571 through the rotating rod 576. When the first planetary gear 54 rotates, the rotating rod 576 rotates synchronously. The rotating rod 576 can carry the plectrum 577 to rotate circumferentially, and pluck the string body 572 during the rotation. The string body 572 can vibrate to achieve sound in the resonance chamber 575, and the sound in the resonance chamber 575 can continuously emit sound; if slippage occurs, the first planetary gear 54 rotates, and the plectrum 577 plucks the string body 572 at this time, and the sound begins to be emitted in the sound chamber 574. When the speed difference between the first transmission shaft 51 and the second transmission shaft 515 increases, the plectrum 577 can pluck the string body 572 at a higher frequency, thereby making the occurrence rhythm of the string body 572 faster. Therefore, this embodiment can effectively determine the risk of slippage by using the frequency of sound generation while feeding back the slippage phenomenon, so as to adopt corresponding countermeasures.

[0050] Furthermore, the first transmission support assembly 4 includes a support shell 44, and an arc-shaped groove 42 is provided on the top of the support shell 44, and the arc-shaped groove 42 can partially accommodate the collar gear 2; A rotating gear 43 is provided in the supporting shell 44, and the top of the rotating gear 43 passes through the supporting shell 44 and meshes with the collar gear 2; The end face of the rotating gear 43 facing away from the slip feedback assembly 5 is connected to an end bearing 45 , a support 48 is fixed to the bottom of the end bearing 45 , and the support 48 extends and is fixed to the supporting base 6 . The other end face of the rotating gear 43 is connected to the slip feedback assembly 5 .

[0051] In this embodiment, the supporting shell 44 is used to accommodate and protect the internal structure. The rotating gear 43 is meshed with the ring gear 2. By fixing the position on the first transmission shaft 51, the first transmission shaft 51 can be fully utilized. The end bearing 45 can carry the rotation of the first rotating shaft or the second transmission shaft 515, and use the pillar 48 for bottom support, thereby ensuring its own structural stability.

[0052] Furthermore, a plurality of oblique support rods 49 are provided on the side of the end bearing 45, one end of the oblique support rod 49 is fixed to the supporting shell 44, and the other end thereof is fixed with a connecting end 46, and the connecting end 46 is hinged to the end bearing 45; An elastic support 47 is provided between the connection ends 46 , and the connection ends 46 are fixed to the elastic support 47 , and the elastic support 47 is in contact with the end bearing 45 .

[0053] In this embodiment, the connecting end 46 is hinged to the end bearing 45, so the inclined support rod 49 can effectively enhance the stability of the position of the end bearing 45. The elastic support 47 does not work under normal circumstances, but when the support problem occurs with the pillar 48, the position of the first transmission shaft 51 is prone to collapse. Therefore, in this embodiment, an elastic support 47 is provided between the end bearings 45. The elastic support 47 can protect the first transmission shaft 51 and the second transmission shaft 515 when the embodiment encounters extreme situations, and support is provided by elastic supporting force.

[0054] Furthermore, a rotation gap 41 is left between the arc-shaped groove 42 and the collar gear 2 : the collar gear 2 can rotate freely, and when the collar gear 2 rotates, it can drive the rotating gear 43 to rotate.

[0055] This embodiment utilizes the rotation gap 41 to avoid wear on the surface of the rotating gear 43, thereby increasing the application time of this embodiment.

[0056] Furthermore, the bearing base 6 includes a plurality of elastic filling layers 62, and the elastic filling layers 62 fill the bearing base 6; The elastic filling layer 62 includes a first filling block 621 and a second filling block 622 . The elastic expansion direction of the first filling block 621 is perpendicular to the elastic expansion direction of the second filling block 622 . The first filling block 621 and the second filling block 622 are staggered.

[0057] In this embodiment, the elastic filling layer 62 in the supporting base 6 is perpendicular to each other through the first filling block 621 and the second filling block 622, so that the force on the elastic filling layer 62 is more uniform. When it is subjected to heavy pressure, it can also effectively prevent the compressed object from rolling, thereby effectively enhancing the bearing capacity of the supporting base 6 in the present invention.

[0058] In this embodiment, a base shell 61 is set to form the basic shape and accommodating space of the supporting base 6, and the first filling blocks 621 and the second filling blocks 622 are staggered: the elastic fillings adjacent to the first filling blocks 621 in each direction are preferentially set to the second filling blocks 622, and the elastic fillings adjacent to the second filling blocks 622 in each direction are preferentially set to the first filling blocks 621, so that the elastic expansion and contraction directions of the first filling blocks 621 and the second filling blocks 622 can complement each other, thereby achieving the purpose of enhancing the carrying capacity of the supporting base 6.
