Specific embodiments

[0014] For the purpose of making the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0015] The present invention provides a high-voltage motor, as Figures 1 to 8 shown, including a motor 1, an output shaft is provided on the motor 1, and a protection component for preventing fragments from flying out when it breaks is provided outside the output shaft; The protection component includes: an annular shell 2, a cover plate 3, a shielding member 4, a sliding rod 5, a sliding block 6, a first spring 7, a limiting component for limiting the sliding block 6, and a lubricating component for lubricating the sliding rod 5; The annular shell 2 is fixedly installed on the outside of the motor 1. The annular shell 2 is located at the output shaft. One end of the shielding member 4 is fixedly connected to the inner wall of the annular shell 2, and the other end is fixedly connected to the cover plate 3. Two sliding blocks 6 are provided. The two sliding blocks 6 are symmetrically and fixedly connected to the surface of the cover plate 3. The sliding block 6 is slidably sleeved outside the sliding rod 5. One end of the sliding rod 5 is fixedly connected to the motor 1, and the first spring 7 is sleeved outside the sliding rod 5.

[0016] During use, when the surface of the output shaft cracks during the use of the motor 1, at this time, the sliding rod 5 is lubricated by the lubricating component, and the limiting component cancels the limit on the sliding block 6. At this time, the compressed first spring 7 releases the acting force and drives the sliding block 6 and the cover plate 3 to move away from the motor 1. The cover plate 3 unfolds the shielding member 4, so that the shielding member 4 covers the outside of the output shaft, thereby being able to block the fragments thrown out due to excessive cracking of the subsequent output shaft and prevent the fragments from being thrown to the outside and hurting people. By lubricating the sliding rod 5, the sliding block 6 can move more smoothly and faster along the sliding rod 5, and then drive the cover plate 3 to unfold the shielding member 4 faster; In the case where the output shaft does not crack, at this time, the shielding member 4 is stored in the annular shell 2, so the shielding member 4 does not cover the outside of the output shaft, avoiding affecting the heat dissipation of the bearing at the output shaft.

[0017] As Figures 2 to 5 shown, the limiting component includes: a vertical plate 8, a clamping block 9, an iron rod 10, a second spring 11, an electromagnet 12, a vibration measuring instrument 24, a controller, and a card slot; The vertical plate 8 is fixedly installed on the outside of the motor 1. The clamping block 9 is slidably arranged on the vertical plate 8. Specifically, a channel is provided inside the vertical plate 8, and the clamping block 9 is slidably arranged in the channel. One end of the iron rod 10 is fixedly connected to the clamping block 9, and the other end extends outside the vertical plate 8. The second spring 11 is sleeved outside the iron rod 10, and both ends of the second spring 11 are fixedly connected to the vertical plate 8 and the clamping block 9 respectively. The clamping groove is opened on the slider 6, and the clamping block 9 extends into the clamping groove. The electromagnet 12 is fixed outside the vertical plate 8, and the vibration measuring instrument 24 is fixed on the inner wall of the ring shell 2. The vibration measuring instrument 24 can monitor the vibration signal of the output shaft. The controller (not shown in the figure) is arranged on the motor 1.

[0018] The vibration measuring instrument 24 is a non-contact laser vibration measuring instrument. By monitoring the rotating output shaft with the vibration measuring instrument 24, fatigue cracks in the output shaft will lead to a decrease in stiffness and a change in mass distribution, resulting in abnormal vibration signals. Especially when the crack expands to the critical size, the vibration amplitude and frequency components will change significantly. The crack is captured by the vibration measuring instrument 24, so as to know in time that the output shaft is cracked. When the output shaft is cracked, at this time the vibration measuring instrument 24 monitors that the output shaft is cracked, and the electromagnet 12 is controlled to be energized through the controller to make it magnetic, so as to attract the iron rod 10 to drive the clamping block 9 to move away from the clamping groove. The clamping block 9 compresses the second spring 11 to deform it, and finally the clamping block 9 leaves the clamping groove, canceling the limit on the slider 6.

[0019] As Figures 2 to 6 shown, the lubrication assembly includes: a sponge ring 14, a mounting assembly for mounting the sponge ring 14, and an injection assembly for injecting lubricating oil into the mounting assembly to lubricate the sponge ring 14; The sponge ring 14 is arranged outside the sliding rod 5, and the mounting assembly is connected to the slider 6.

[0020] When the clamping block 9 moves away from the clamping groove, it cooperates with the injection assembly to inject lubricating oil into the mounting assembly, so that the sponge ring 14 is lubricated.

[0021] As Figures 3 to 5 shown, the injection assembly includes: a cylinder block 15, a hose 16, a box body 17, a one-way valve 18, a plug plate 19, a third spring 20, a push rod 21, and a wedge block 22; The cylinder block 15 is fixedly installed at one end of the vertical plate 8, the box body 17 is fixedly installed on the top of the cylinder block 15, the hose 16 connects the mounting assembly and the cylinder block 15, a channel is provided between the cylinder block 15 and the box body 17, the one-way valves 18 are respectively arranged in the channel and the hose 16, the plug plate 19 is arranged in the cylinder block 15, the third spring 20 is arranged on the side of the plug plate 19 away from the clamping block 9, one end of the push rod 21 is fixedly installed at the end of the plug plate 19 close to the clamping block 9, and the other end extends outside the cylinder block 15. The wedge block 22 is fixed on the clamping block 9, and the wedge surface of the wedge block 22 can abut against the push rod 21. The cylinder block 15 and the box body 17 are filled with lubricating oil.

[0022] When the clamping block 9 moves away from the card slot, it drives the wedge block 22 to move accordingly. The wedge surface of the wedge block 22 squeezes the ejector rod 21, causing it to drive the plug plate 19 to move away from the vertical plate 8. At the same time, the plug plate 19 compresses the third spring 20, causing it to deform and generate a force. As the plug plate 19 moves, the lubricating oil in the cylinder block 15 is squeezed outwards. At this time, the one-way valve 18 in the hose 16 opens, and the one-way valve 18 in the channel closes. The lubricating oil in the cylinder block 15 is squeezed into the installation assembly through the hose 16.

[0023] As Figures 2 to 6 shown, the installation assembly includes: a pair of annular pipes 23, a moving block 25, a fourth spring 13, spray holes, and a connecting pipe 33; A pair of annular pipes 23 are sleeved outside the sponge ring 14. The connecting pipe 33 is symmetrically connected to the inner side of one of the annular pipes 23. The inner side of the other annular pipe 23 is provided with a jack corresponding to the connecting pipe 33. The connecting pipe 33 extends into the corresponding jack. The spray holes are arranged equidistantly around the inner side of the annular pipe 23. The moving block 25 is fixedly installed on the side of the annular pipe 23 close to the slider 6. A moving groove cooperating with the moving block 25 is provided on the slider 6. The fourth spring 13 fixedly connects the side of the moving block 25 away from the sponge ring 14 to the inner wall of the moving groove. One end of the hose 16 communicates with one of the annular pipes 23; An extrusion block 26 is fixedly installed at the bottom of the annular pipe 23. An inclined surface 27 is provided inside the extrusion block 26. An installation plate 28 is fixedly installed at the bottom of the slider 6. A groove is provided on one side of the installation plate 28. A round rod 29 is slidably installed in the groove.

[0024] After the lubricating oil is squeezed into the annular pipe 23 communicated with it through the hose 16, due to the blocking of the spray holes by the sponge ring 14, the speed of the lubricating oil entering the annular pipe 23 is greater than the speed of the lubricating oil flowing out of the spray holes, causing the annular pipe 23 to be filled with lubricating oil. The annular pipe 23 injects the lubricating oil into the other annular pipe 23 through the connecting pipe 33, causing both annular pipes 23 to be filled with lubricating oil. With the subsequent injection of lubricating oil, the lubricating oil flows to the sponge ring 14 through the spray holes. The sponge ring 14 absorbs the lubricating oil, enabling the sponge ring 14 to lubricate the sliding rod 5 when it moves along the sliding rod 5 subsequently; When the shielding member 4 is fully expanded, the ring tube 23 is separated from the slide rod 5, and the round rod 29 is pushed upward to cooperate with the inclined surface 27 to push the pair of squeeze blocks 26 away from each other, thereby leading the pair of ring tubes 23 to move away from each other. The inner side of the squeeze block 26 is provided with a plane connected to the inclined surface 27. Finally, the round rod 29 is located at the plane, and the ring tube 23 and the moving block 25 move accordingly to compress the fourth spring 13 to make it deform. With the separation of the pair of ring tubes 23, the wrapping of the sponge ring 14 is cancelled. At this time, the sponge ring 14 can be removed, and then the slider 6 is pushed to reset, and the electromagnet 12 is powered off to make it lose its magnetism. Then the second spring 11 is reset and the card block 9 is reset into the card slot, so that the slider 6 is limited. At the same time, the card block 9 is reset with the wedge block 22. At this time, the compressed third spring 20 releases its force and resets the plug plate 19. At this time, lubricating oil is pumped into the cylinder body 15. At this time, the soft The one-way valve 18 in the tube 16 is closed, and the one-way valve 18 in the channel is opened, and the lubricating oil is drawn into the cylinder body 15 through the channel for replenishment, and then the slide rod 5 is cleaned and the lubricating oil on its surface is cleaned. Since the probability of the output shaft breaking is low, if the lubricating oil accumulates on the slide rod 5 or the sponge ring 14 for a long time, it will cause the lubricating oil to fail and absorb external dust and impurities, affecting the next movement of the slider 6 and the lubrication of the slide rod 5 by the sponge ring 14. After the slide rod 5 is cleaned, a new sponge ring 14 is sleeved on the outside of the slide rod 5 so that the sponge ring 14 is located between a pair of ring tubes 23, and then the round rod 29 is reset downward. At this time, the compressed fourth spring 13 releases the force to reset the moving block 25 and the ring tube 23, and the pair of ring tubes 23 clamps the sponge ring 14 outside the slide rod 5. Later, when the ring tube 23 moves, it can push the sponge ring 14 to slide along the surface of the slide rod 5 to lubricate it.

[0025] like Figure 4 and Figure 7 As shown, a gas injection machine 30 is fixedly installed on the front side of the motor 1 , and the shielding member 4 is specifically a set component made of rubber material. A cavity 32 is provided inside the shielding member 4 , and the output end of the gas injection machine 30 is connected to the cavity 32 through a pipe 31 .

[0026] While the shielding member 4 is unfolded, the controller controls the gas injection machine 30 to quickly inject gas into the cavity 32 through the pipeline 31, so that the shielding member 4 expands. Finally, when the shielding member 4 is wrapped around the outside of the output shaft, the shielding member 4 is in an expanded state. The expanded shielding member 4 can buffer the impact of debris when the shielding member 4 is impacted by debris, so that the shielding member 4 is not easily damaged.

[0027] like Figure 3 As shown, a pair of ring tubes 23 can clamp and fix the sponge ring 14, and the sliding rod 5 is made of stainless steel with a smooth surface.

[0028] The annular tube 23 can push the sponge ring 14 to move along the surface of the slide rod 5 .

[0029] Working principle: When in use, during the operation of the motor 1, when the surface of the output shaft cracks, at this time, the vibration measuring instrument 24 monitors the cracking of the output shaft. The controller controls the electromagnet 12 to be energized, making it magnetic, so as to attract the iron rod 10 to drive the clamping block 9 to move away from the clamping groove. The clamping block 9 compresses the second spring 11 to deform it. Eventually, the clamping block 9 leaves the clamping groove, canceling the limit on the slider 6. When the clamping block 9 moves away from the clamping groove, it drives the wedge block 22 to move accordingly. The wedge surface of the wedge block 22 squeezes the ejector rod 21 to drive the plug plate 19 to move away from the vertical plate 8. At the same time, the plug plate 19 compresses the third spring 20 to deform and generate a force. As the plug plate 19 moves, the lubricating oil in the cylinder block 15 is squeezed outwards. At this time, the one-way valve 18 in the hose 16 opens, and the one-way valve 18 in the channel closes. The lubricating oil in the cylinder block 15 is squeezed into the annular pipe 23 communicated with it through the hose 16. Due to the sponge ring 14 blocking the spray holes, the speed of the lubricating oil entering the annular pipe 23 is greater than the speed of the lubricating oil flowing out from the spray holes, making the annular pipe 23 filled with lubricating oil. The annular pipe 23 injects the lubricating oil into another annular pipe 23 through the connecting pipe 33, making both annular pipes 23 filled with lubricating oil. With the subsequent injection of lubricating oil, the lubricating oil flows to the sponge ring 14 through the spray holes. The sponge ring 14 absorbs the lubricating oil, and then the compressed first spring 7 releases the force to drive the slider 6 and the cover plate 3 to move away from the motor 1. The cover plate 3 unfolds the shielding member 4, making the shielding member 4 cover the output shaft, so as to shield the fragments thrown out due to excessive cracking of the subsequent output shaft and prevent the fragments from being thrown to the outside and hurting people. By lubricating the slide rod 5, the slider 6 can move more smoothly and faster along the slide rod 5, and then drive the cover plate 3 to unfold the shielding member 4 faster; In the case where the output shaft does not crack, at this time, the shielding member 4 is stored in the annular shell 2, so the shielding member 4 will not cover the output shaft, avoiding affecting the heat dissipation of the bearing at the output shaft; While the shielding member 4 is unfolding, the controller controls the air injector 30 to quickly inject gas into the cavity 32 through the pipeline 31, making the shielding member 4 expand. Eventually, when the shielding member 4 covers the output shaft, the shielding member 4 is in an expanded state. Through the expanded shielding member 4, when the shielding member 4 is impacted by the fragments, it can buffer the impact of the fragments, making the shielding member 4 not easily damaged; When the shielding member 4 is fully deployed, at this time the annular tube 23 disengages from the sliding rod 5. Then, the round rod 29 is pushed upward to cooperate with the inclined surface 27 to push a pair of extrusion blocks 26 away from each other, thereby driving a pair of annular tubes 23 to move away from each other. A plane connected to the inclined surface 27 is provided inside the extrusion block 26. Finally, the round rod 29 is located at the plane. The annular tube 23 drives the moving block 25 to move accordingly and compresses the fourth spring 13 to deform it. As the pair of annular tubes 23 separate, the wrapping of the sponge ring 14 is cancelled, and at this time the sponge ring 14 can be removed. Then, the slider 6 is pushed back to its original position, the electromagnet 12 is powered off to lose its magnetism, and then the second spring 11 returns to its original position and drives the latch 9 back into the card slot to limit the slider 6. At the same time, the latch 9 drives the wedge-shaped block 22 back to its original position. At this time, the compressed third spring 20 releases the acting force and drives the plug plate 19 back to its original position. At this time, lubricating oil is pumped into the cylinder body 15. At this time, the one-way valve 18 in the hose 16 is closed, and the one-way valve 18 in the channel is opened. The lubricating oil is pumped into the cylinder body 15 through the channel for replenishment. Then, the sliding rod 5 is cleaned to remove the lubricating oil on its surface. Since the probability of the output shaft breaking is relatively low, if the lubricating oil accumulates on the sliding rod 5 or the sponge ring 14 for a long time, it will cause the lubricating oil to fail and adsorb external dust and impurities, affecting the movement of the slider 6 next time and the lubrication of the sliding rod 5 by the sponge ring 14. Therefore, the lubricating oil needs to be cleaned and the sponge ring 14 needs to be replaced. After cleaning the sliding rod 5, a new sponge ring 14 is sleeved outside the sliding rod 5 so that the sponge ring 14 is located between a pair of annular tubes 23. Then, the round rod 29 is reset downward. At this time, the compressed fourth spring 13 releases the acting force and drives the moving block 25 and the annular tube 23 back to their original positions. A pair of annular tubes 23 clamp the sponge ring 14 outside the sliding rod 5. Subsequently, when the annular tube 23 moves, it can push the sponge ring 14 to slide along the surface of the sliding rod 5 to lubricate it.

[0030] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
