[0012] A generator set alarm method of a generator set alarm device comprises the following steps: S1. First, the rotating shaft of the generator set is fixedly connected to one end of the main shaft. At this time, the rotating shaft of the generator set will drive the main shaft to rotate accordingly; S2.1. When the generator set is operating normally, the paddle on the main shaft will continuously strike the fixed plate on the slide as the main shaft rotates, pushing the slide to move, causing the second interface on the slide to continuously contact the first interface, energizing the first indicator light. The first indicator light will flash, and the flashing frequency will be recorded. At this time, the generator set's shaft speed is normal. If the recorded frequency exceeds the threshold, promptly report it to the user, check whether the generator load exceeds the limit, and reduce the speed to within the safe threshold. S2.2. When the main shaft stops, the movement of the slide stops, the second interface is no longer in contact with the first interface, and the capacitor continues to discharge for a period of time.

During spindle rotation, vibrations are generated, driving the main shaft to vibrate. This vibration is transmitted through the contact block to the connecting plate. A spring is installed at the top of the connecting plate, amplifying the vibrations. This spring also drives the drawing pen to leave a vibration path on the waveform drawing board. The waveform drawing board integrates the vibration path into a vibration curve. When the spindle vibration exceeds the preset threshold, the second indicator light is triggered to issue a secondary alarm. At this time, the spindle bearing may be abnormal, requiring shutdown and maintenance. S3.2. When the second indicator light triggers the secondary alarm, the frequency data recorded when the main shaft hits the fixed plate during rotation is used to determine whether the rotation frequency of the shaft exceeds 10% of the set threshold. If it exceeds, a level 3 alarm is triggered, and the user is notified of the generator set status remotely. At the same time, the generator is shut down immediately, and the vibration spectrum 10 minutes before the fault is retrieved to locate the mechanical fault point.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, a speed monitoring device is provided. When the generator set is operating normally, the paddle on the main shaft will continuously hit the fixed plate on the skateboard as the main shaft rotates, and push the skateboard to move, so that the second interface on the skateboard is continuously in contact with the first interface, so that the first indicator light is energized, and the first indicator light will be in a stroboscopic state. When the main shaft stops, the movement state of the skateboard stops, the second interface is not in contact with the first interface, and the capacitor will continue to discharge for a period of time. The structure of the electric heating microfiber gradually stretches after discharge, so that the second interface is in contact with the first interface, and the first indicator light will be on after it goes out. At this time, the shaft of the generator set is in a stopped state during operation. The real-time state of the shaft of the generator set can be effectively and intuitively seen according to the real-time changes of the first indicator light, which can better cope with different emergency states.

[0014] 2. In the present invention, by setting a rotating device, vibration will be generated during the rotation of the shaft and drive the main shaft to vibrate. The vibration will be transmitted through the contact block to the connecting plate. A spring is set at the top of the connecting plate. The spring is used to amplify the vibration.

[0017] Example 1: Figure 1-Figure 5 As shown, the present invention provides a generator set alarm device, comprising: The speed monitoring device 1 is used to detect the state of the generator set shaft during rotation, and includes a monitoring shell 102. A processor 104 is fixedly connected to one side of the monitoring shell 102, a first indicator light 101 is fixedly connected to the top of the processor 104, a support platform 107 is fixedly connected to the bottom end of the inner wall of the monitoring shell 102, and a rotating device 2 for connecting to the shaft and outputting the state of the shaft is provided in the middle of the monitoring shell 102.

[0018] It should be noted that by setting up the speed monitoring device 1, when the generator set is operating normally, the paddle 202 on the main shaft 201 will continuously hit the fixed plate 1010 on the skateboard 106 as the main shaft 201 rotates, and push the skateboard 106 to move, so that the second interface 109 on the skateboard 106 is continuously in contact with the first interface 108, so that the first indicator light 101 is energized, and the first indicator light 101 will be in a strobe state. When the main shaft 201 stops, the movement of the skateboard 106 stops, the second interface 109 is not in contact with the first interface 108, the capacitor 103 will continue to discharge for a period of time, and the electric thermal microfiber 105 will gradually stretch its own structure after discharge, so that the second interface 109 is in contact with the first interface 108, and the first indicator light 101 will be on after it goes out. At this time, the shaft of the generator set is in a stopped state during operation. The real-time changes of the first indicator light 101 can effectively and intuitively show the real-time state of the shaft of the generator set, which can better cope with different emergency states.

[0019] The top of the support platform 107 is provided with a plurality of balls 1011 in a rectangular array, the top of the support platform 107 is slidably connected to a slide plate 106, the middle of the top of the slide plate 106 is fixedly connected to a fixed plate 1010, the middle of one side of the slide plate 106 is fixedly connected to a second interface 109, the middle of one side of the inner wall of the monitoring shell 102 is fixedly connected to a first interface 108, the other side of the slide plate 106 is fixedly connected to two electric heating microfibers 105, and a capacitor 103 is fixedly connected to the upper position on one side of the rear end of the inner wall of the monitoring shell 102.

[0020] It should be noted that after the capacitor 103 finishes discharging the electric thermal fiber 105, the length of the electric thermal fiber 105 changes, so that the first interface 108 cooperates with the second interface 109. Therefore, the first indicator light 101 will eventually be in a constantly lit state. However, when the first indicator light 101 is constantly lit, it is necessary to first perform a shutdown self-inspection on the speed monitoring device 1. By manually rotating the main shaft, manually rotating the main shaft 201, and using the paddle 202 to pry the fixed plate 1010, observe whether the first indicator light 101 flashes. If it flashes, the generator shaft has stopped. If there is no change, the paddle 202 or the torsion spring 205 in the rotating device 2 is damaged.

[0021] The rotating device 2 includes a main shaft 201, and two mounting brackets 203 are arranged in a circular array in the middle of the side wall of the main shaft 201. The inner wall of the mounting bracket 203 is rotatably connected to a paddle 202, and the bottom end of the paddle 202 is fixedly connected to a fixing rod 204, and the side wall of the fixing rod 204 is fixedly connected to a torsion spring 205.

[0022] The first interface 108 and the second interface 109 are located on the same horizontal axis. The first interface 108 passes through the monitoring shell 102 and is electrically connected to the processor 104. The two electrothermal microfibers 105 are respectively fixedly connected to the other side of the inner wall of the monitoring shell 102. The electrothermal microfiber 105 is made of carbon fiber and silicone rubber spinning, and the electrothermal microfiber 105 is spring-shaped. The two electrothermal microfibers 105 are both electrically connected to the capacitor 103. Several balls 1011 are respectively slidably connected to the bottom end of the skateboard 106. A slide groove is opened in the middle of the top of the support platform 107, and the middle of the bottom end of the skateboard 106 is slidably connected to the middle of the bottom end of the skateboard 106.

[0023] It should be noted that the electric heating microfiber 105 is made of carbon fiber and silicone rubber using the electrostatic spinning method. It will shrink and deform when power is supplied, and return to its original state when power is stopped. Moreover, since the electric heating microfiber 105 is a contracted spring-like structure when power is supplied, the slide 106 can return to its initial position, and at this time the first interface 108 is disconnected from the second interface 109.

[0024] The main shaft 201 completely passes through the shell 301 and the side wall of the monitoring shell 102. The paddle 202 and the fixing plate 1010 are located on the same vertical axis. The two mounting brackets 203 are fixedly connected to the side wall of the main shaft 201. The two ends of the torsion spring 205 are respectively fixedly connected to the side wall of the main shaft 201.

[0025] Working principle: When the generator set is operating normally, the paddle 202 on the main shaft 201 will continuously hit the fixed plate 1010 on the skateboard 106 as the main shaft 201 rotates, and push the skateboard 106 to move, so that the second interface 109 on the skateboard 106 is continuously in contact with the first interface 108, so that the first indicator light 101 is energized, and the first indicator light 101 will be in a strobe state. When the main shaft 201 stops, the movement of the skateboard 106 stops, the second interface 109 is not in contact with the first interface 108, and the capacitor 103 will continue to discharge for a period of time. After the discharge, the structure of the electric thermal microfiber 105 gradually stretches, so that the second interface 109 is in contact with the first interface 108, and the first indicator light 101 will be on after it goes out. At this time, the shaft of the generator set is in a stopped state during operation.

[0026] Example 2: Figure 6-Figure 7 As shown, the present invention provides a generator set alarm device, comprising: The vibration monitoring device 3 is used to detect the vibration generated when the shaft rotates, and includes a shell 301. The bottom end of the inner wall of the shell 301 has four damping telescopic rods 307 in a rectangular array. The side walls of the four damping telescopic rods 307 are respectively provided with a first spring 306. The other side of the shell 301 is fixedly connected to a mounting plate 303, and the middle of the top of the shell 301 is fixedly connected to a control terminal 4.

[0027] It should be noted that, by setting up the rotating device 2, vibration will be generated during the rotation of the shaft and drive the main shaft 201 to vibrate. The vibration will be transmitted through the contact block 3010 to the connecting plate 308. A spring 3011 is provided at the top of the connecting plate 308. The spring 3011 is used to amplify the vibration. At the same time, it will drive the drawing pen 3014 to leave a vibration path on the waveform drawing board 304. The waveform drawing board 304 is used to integrate the vibration path into a vibration curve. When the vibration of the main shaft 201 exceeds the preset threshold, the second indicator light 302 will be triggered to alarm, effectively amplifying the vibration amplitude of the shaft and drawing a vibration curve graph with more amplitude, so that the vibration state of the main shaft 201 can be better seen, effectively improving the detection accuracy.

[0028] The other side of the top of the mounting plate 303 is fixedly connected to a waveform drawing plate 304, and the other side of the waveform drawing plate 304 is fixedly connected to a second indicator light 302. A groove 305 is fixedly connected to the upper position of the other side of the shell 301. The top of the shell 301 is provided with a plurality of springs 3011 in a rectangular array, and the bottom ends of the plurality of springs 3011 are fixedly connected to a connecting plate 308. Connecting rods 309 are fixedly connected to the middle of both sides of the connecting plate 308, and the bottom ends of the two connecting rods 309 are respectively fixedly connected to contact blocks 3010. A sleeve 3012 is fixedly connected to the middle of the other side of the connecting plate 308, and a sliding rod 3013 is slidably connected to the inner wall of the sleeve 3012. The side wall of the sliding rod 3013 is sleeved with a second spring 3015, and the other end of the sliding rod 3013 is fixedly connected to a drawing pen 3014.

[0029] It should be noted that the main shaft 201 transmits the vibration to the connecting plate 308 through the contact block 3010. The spring 3011 at the top of the connecting plate 308 will continuously amplify the vibration after being vibrated. The side wall of the slide bar 3013 is provided with a second spring 3015, which keeps one end of the drawing pen 3014 in contact with the waveform drawing board 304, so that the drawing pen 3014 leaves a mark on the waveform drawing board 304. In combination with the stroboscopic frequency detection of the speed monitoring device 1, it can be more intuitive to judge whether there is equipment damage inside the generator set and trigger a third-level alarm.

[0030] The four damping telescopic rods 307 are fixedly connected to the bottom end of the monitoring shell 102, the two contact blocks 3010 are rotatably connected to the front and rear sides of the side walls of the main shaft 201 respectively, one end of the sleeve 3012 passes through the groove 305 and is fixedly connected to the middle of the other side of the connecting plate 308, the drawing pen 3014 is slidingly connected to one side of the waveform drawing plate 304, one end of the second spring 3015 is fixedly connected to the other end of the sleeve 3012, and the other end of the second spring 3015 is fixedly connected to one side of the drawing pen 3014.

[0031] Working principle: By setting up a rotating device 2, vibration will be generated during the rotation of the shaft and drive the main shaft 201 to vibrate. The vibration will be transmitted through the contact block 3010 to the connecting plate 308. A spring 3011 is set at the top of the connecting plate 308. The spring 3011 is used to amplify the vibration. At the same time, it will drive the drawing pen 3014 to leave a vibration path on the waveform drawing board 304. The waveform drawing board 304 is used to integrate the vibration path into a vibration curve. When the vibration of the main shaft 201 exceeds the preset threshold, the second indicator light 302 will be triggered to alarm.

[0032] Example 3: Figures 1-8 As shown, a generator set alarm method of a generator set alarm device includes the following steps: S1. First, the rotating shaft of the generator set during power generation is fixedly connected to one end of the main shaft 201. At this time, the rotating shaft of the generator set will drive the main shaft 201 to rotate accordingly; S2.1. When the generator set is operating normally, the paddle 202 on the main shaft 201 continuously strikes the fixed plate 1010 on the slide 106 as the main shaft 201 rotates, pushing the slide 106 to move, causing the second interface 109 on the slide 106 to continuously contact the first interface 108, energizing the first indicator light 101. The first indicator light 101 will flash, and the flashing frequency will be recorded. At this time, the generator set's shaft speed is normal. If the recorded frequency exceeds the threshold, the user will be notified promptly, and the generator load will be checked to see if it exceeds the limit, and the speed will be reduced to within the safe threshold. S2.2. When the main shaft 201 stops rotating, the movement of the slide 106 stops, the second interface 109 is no longer in contact with the first interface 108, and the capacitor 103 continues to discharge for a period of time. After the discharge, the electrothermal microfiber 105 gradually stretches, causing the second interface 109 to contact the first interface 108. The first indicator light 101 will remain on after being extinguished. At this time, the shaft of the generator set is in a stopped state during operation, and a level 1 alarm will be triggered. S3.1. During the rotation of the shaft, vibration is generated, driving the main shaft 201 to vibrate. This vibration is transmitted through the contact block 3010 to the connecting plate 308. A spring 3011 is provided at the top of the connecting plate 308, which amplifies the vibration. This spring 3011 also drives the drawing pen 3014 to leave a vibration path on the waveform drawing board 304. The waveform drawing board 304 integrates the vibration path into a vibration curve. When the vibration of the main shaft 201 exceeds a preset threshold, the second indicator light 302 is triggered to issue a secondary alarm, indicating that the shaft bearing may be abnormal and requires shutdown for maintenance. S3.2. When the second indicator light 302 triggers the secondary alarm, the frequency data recorded when the main shaft 201 hits the fixed plate 1010 during rotation is used to determine whether the rotation frequency of the shaft exceeds 10% of the set threshold. If it exceeds, a level 3 alarm is triggered, and the user is notified of the generator set status remotely. At the same time, the generator is shut down immediately, and the vibration spectrum 10 minutes before the fault is retrieved to locate the mechanical fault point.

8. The generator set alarm method of any one of claims 1 to 7, characterized in that: The following steps are involved: S1. First, the rotating shaft of the generator set during power generation is fixedly connected to one end of the main shaft (201). At this time, the rotating shaft of the generator set will drive the main shaft (201) to rotate accordingly; S2.

1. When the generator set is operating normally, the paddle (202) on the main shaft (201) will continuously strike the fixed plate (1010) on the slide plate (106) as the main shaft (201) rotates, and pushes the slide plate (106) to move, so that the second interface (109) on the slide plate (106) is continuously in contact with the first interface (108), so that the first indicator light (101) is powered on, and the first indicator light (101) will be in a stroboscopic state, and the stroboscopic frequency is recorded. At this time, the shaft speed of the generator set is normal. If the recorded frequency exceeds the threshold, the user is promptly notified, and the generator load is checked to see if it exceeds the limit, and the speed is reduced to within the safety threshold; S2.2, when the main shaft (201) stops rotating, the movement state of the slide plate (106) stops, the second interface (109) is not in contact with the first interface (108), the capacitor (103) will continue to discharge for a period of time, and the structure of the electrothermal microfiber (105) will gradually stretch after the discharge, so that the second interface (109) is in contact with the first interface (108), and the first indicator light (101) will be constantly on after being extinguished. At this time, the shaft of the generator set is in a stopped state during operation, and a first-level alarm will be triggered; S3.

1. During the rotation of the shaft, vibration is generated and drives the main shaft (201) to vibrate. The vibration is transmitted through the contact block (3010) to the connecting plate (308). A spring (3011) is provided at the top of the connecting plate (308). The spring (3011) is used to amplify the vibration. At the same time, the drawing pen (3014) is driven to leave a vibration path on the waveform drawing board (304). The vibration path is integrated into a vibration curve using the waveform drawing board (304). When the vibration of the main shaft (201) exceeds a preset threshold, the second indicator light (302) is triggered to issue a secondary alarm. At this time, the bearing of the shaft may be abnormal and the machine needs to be shut down for maintenance. S3.

2. When the second indicator light (302) triggers the secondary alarm, the frequency data recorded when the main shaft (201) hits the fixed plate (1010) during rotation is used to determine whether the rotation frequency of the shaft exceeds 10% of the set threshold. If it exceeds, a third-level alarm is triggered, and the user is notified of the generator set status remotely. At the same time, the generator is shut down immediately, and the vibration spectrum 10 minutes before the fault is retrieved to locate the mechanical fault point.
