Description

Technical Field

[0001] This invention relates to the field of generator set technology, specifically a generator set with a fault self-diagnosis function. Background Technology

[0002] Generator sets, as complete sets of mechanical equipment that convert other forms of energy into electrical energy, play an indispensable role in all sectors of modern society. Whether it's powering large equipment in industrial production, providing electricity for the normal operation of commercial venues, or ensuring power supply in special scenarios such as outdoor construction and emergency rescue, generator sets have become an important choice for power supply due to their flexibility and reliability.

[0003] With continuous technological advancements, generator set technology is also constantly evolving. From early simple mechanical structures to today's complex systems integrating multiple advanced technologies, the performance and functionality of generator sets have been significantly improved. Among these advancements, generator sets with self-diagnostic fault functions have become an important development direction in recent years. These generator sets can monitor their own operating status in real time, and through built-in sensors and intelligent control systems, they can provide early warnings and diagnose potential faults, greatly improving the reliability and maintenance efficiency of the generator set and reducing power outage losses caused by sudden failures.

[0004] During generator set operation, a large amount of heat is generated inside the chassis. If the high-temperature areas inside the chassis are not effectively cooled, it will seriously affect the performance and lifespan of the generator set. First, high temperatures will accelerate the wear and aging of internal engine components, reducing the engine's reliability and service life.

[0005] Generator sets generate vibrations of varying degrees during operation. For the generator set itself, long-term vibration can lead to loosening, wear and fatigue damage of parts, reducing the reliability and service life of the generator set. Strong vibrations may also damage surrounding buildings and equipment. Summary of the Invention

[0006] The purpose of this invention is to provide a generator set with a fault self-diagnosis function to solve the problems raised in the prior art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] The generator set with fault self-diagnosis function includes a chassis, a generator set, a vibration damping unit, and a heat dissipation unit. The chassis is placed on a horizontal ground. The generator set is fixedly connected to the vibration damping unit, which has the function of reducing the vibration generated when the generator set is working. The vibration damping unit is fixedly connected to the heat dissipation unit, which has the function of reducing the temperature inside the chassis.

[0009] The chassis is used to mount and fix the generator set, vibration damping unit, and heat dissipation unit. The generator set is used to provide power, the vibration damping unit is used to reduce the vibration generated by the generator set during operation, and the heat dissipation unit is used to dissipate the heat generated by the generator set inside the chassis, thereby achieving cooling. When the generator set is working inside the chassis, the vibration damping unit reduces the vibration generated by the generator set to avoid damage or loosening of the generator set parts, and the heat dissipation unit dissipates the heat generated by the generator set in a timely manner to avoid high temperature causing generator set failure.

[0010] Furthermore, the shock absorption unit includes a support plate, a striker, a quartz block, a fixed cylinder, a slide groove, a guide post, and a folding plate. The support plate is fixedly connected to the generator set, the support plate is fixedly connected to the striker, the striker is slidably connected to the fixed cylinder, the quartz block is fixedly installed inside the fixed cylinder, the fixed cylinder is fixedly installed inside the chassis, the slide groove is fixedly installed inside the chassis, one end of the guide post is fixedly connected to the fixed cylinder, the other end of the guide post is slidably connected to the folding plate, and the folding plate is slidably installed inside the slide groove.

[0011] Furthermore, the shock absorption unit also includes a shock absorption spring, a push rod, a first electromagnet, a second electromagnet, a sliding magnet, a fixed box, and a straight rod. One end of the shock absorption spring is fixedly connected to the folding plate, and the other end of the shock absorption spring is fixedly connected to the slide groove. One end of the push rod is fixedly connected to the lower surface of the support plate, and the other end of the push rod is fixedly connected to the sliding magnet. The push rod is slidably connected to the first electromagnet. The first electromagnet is fixedly installed at the upper end of the fixed box, and the second electromagnet is fixedly installed at the lower end of the fixed box. The sliding magnet is slidably installed inside the fixed box. The fixed box is fixedly installed inside the chassis. One end of the straight rod is rotatably connected to the impact rod, and the other end of the straight rod is rotatably connected to the folding plate. The folding plate is electrically connected to the first electromagnet and the second electromagnet.

[0012] When the generator set is operating, it vibrates up and down. When the generator set moves downwards, on one hand, the support plate pushes the push rod, causing the sliding magnet to move downwards along the fixed box; on the other hand, the support plate pushes the impact rod downwards along the fixed cylinder and strikes the quartz block, generating a current that is detected by the controller. When the current generated by the quartz block is detected and enters the controller, the controller changes the direction of the current entering the drive coil, starting the current from the drive coil at the left end of the guide post. When the impact rod pushes the straight rod, the straight rod pushes the folding plate to move to the left along the slide groove and compresses the damping spring for shock absorption. At this time, the folding plate moves to the left along the guide post, reducing the effective number of turns of the drive coil and lowering the resistance. This causes the current flowing into the second electromagnet through the folding plate to gradually increase, making the second electromagnet energized and exhibiting the same polarity as the sliding magnet, thereby resisting the downward-moving sliding magnet, reducing the moving distance of the sliding magnet, and reducing... When the generator set vibrates, as it moves upward, the support plate drives the push rod and sliding magnet upward along the fixed box. Simultaneously, the support plate drives the impact rod upward along the fixed cylinder. At this point, the impact rod no longer strikes the quartz block, and the controller restores the current direction flowing into the drive coil, starting the current flow from the right end of the guide post. Under the combined effect of the impact rod pulling the straight rod upward and the self-restoring force of the damping spring, the straight rod pushes the folding plate to the right along the slide groove. The folding plate then slides to the right along the guide post, reducing the effective number of turns in the drive coil and lowering its resistance. This causes the current flowing into the first electromagnet through the folding plate to gradually increase, making the first electromagnet energized and exhibiting the same polarity as the sliding magnet. This resists the upward-moving sliding magnet, reducing its movement distance and collectively reducing the generator set vibration, protecting the generator set, and extending its service life.

[0013] Furthermore, the heat dissipation unit includes an upper rack, a gear, a bent rod, a lower rack, a vacuum chamber, and a push plate. The upper rack is fixedly connected to the bent plate, the upper rack is meshed with the gear, the gear is rotatably connected to one end of the bent rod, the other end of the bent rod is connected to a fixed wheel of the chassis, the gear is meshed with the lower rack, the vacuum chamber is fixedly connected to the chassis, and the push plate is slidably installed inside the vacuum chamber.

[0014] Furthermore, the heat dissipation unit also includes an air supply pipe, an exhaust pipe, a straight pipe, a first fixing ring, a second fixing ring, and a compression block. One end of the air supply pipe is electrically connected to the vacuum chamber, and the air supply pipe is electrically connected to the exhaust pipe. The exhaust pipe is fixedly installed inside the chassis. The straight pipe is electrically connected to the exhaust pipe. The straight pipe consists of rigid pipes at both ends and an elastic pipe in the middle. The first fixing ring is fixedly installed at the rigid pipe of the straight pipe, and the second fixing ring is fixedly installed at the rigid pipe of the straight pipe. The compression block is slidably installed between the first fixing ring and the second fixing ring.

[0015] Furthermore, the heat dissipation unit also includes an elastic shrink ring, a pull rope, a circular plate, a memory spring, a fixing rod, and a sliding plate. The elastic shrink ring is fixedly connected to the extrusion block. One end of the pull rope is fixedly connected to the extrusion block, and the other end of the pull rope passes through a straight tube and is fixedly connected to the circular plate. One end of the memory spring is fixedly connected to the circular plate, and the other end of the memory spring is fixedly connected to the fixing rod. The fixing rod is fixedly connected to the straight tube. One end of the sliding plate is fixedly connected to the lower rack, and the other end of the sliding plate is fixedly connected to the push plate. The sliding plate is slidably connected to the vacuum chamber.

[0016] When the folding plate moves to the left, the upper rack drive gear rotates counterclockwise around the bent rod, which in turn drives the lower rack to move to the right. At this time, the rack drives the slide plate to pull the push plate to the right, compressing the high-temperature gas in the second chamber of the vacuum chamber and expelling it through the one-way exhaust valve. Simultaneously, outside air is drawn into the first chamber through the one-way intake valve. When the folding plate moves to the right, the upper rack drive gear rotates clockwise around the bent rod, which in turn drives the lower rack to move to the left. At this time, the rack drives the slide plate to push the push plate to the left, compressing the gas in the first chamber of the vacuum chamber and delivering it to the air supply pipe through the one-way exhaust valve. Simultaneously, high-temperature gas from inside the casing is drawn into the second chamber through the one-way intake valve. The gas in the gas supply pipe is transported through the exhaust pipe to the straight pipe and discharged into the chassis for heat exchange. This dissipates the high temperature generated by the generator set inside the chassis. Since different areas of the generator set generate different amounts of heat, in the high-temperature zone, when the temperature is too high, the memory spring contracts due to heat, thereby pulling the circular plate and driving the pull rope. This causes the extrusion block to move along the first and second fixed rings, extruding the straight pipe elastic tube and reducing the flow diameter at the straight pipe elastic tube. With the flow velocity in the exhaust pipe remaining constant, the smaller diameter flowing through the straight pipe elastic tube increases the gas flow velocity, accelerates the heat exchange in the high-temperature zone, and further improves the heat exchange rate in the high-temperature zone inside the chassis.

[0017] Furthermore, the ratio of the number of teeth of the upper rack to the lower rack is 3:1 to 9:1.

[0018] In order to convert the vertical displacement of the shock-absorbing support plate into a small displacement of the upper rack through the transmission of the straight rod, and then into a large displacement of the lower rack under the transmission of the gear, it is convenient for the slide to push the push plate to draw in sufficient air from the outside or sufficient high-temperature gas from the chassis. During the left and right movement of the push plate, heat exchange takes place inside the chassis, improving heat dissipation efficiency.

[0019] Furthermore, a drive coil is provided on the guide post, and a conductive ring is provided at the contact end between the folding plate and the guide post.

[0020] In order to facilitate the control of the first and second electromagnets to suppress the movement amplitude of the sliding magnet, thereby reducing the vibration amplitude of the generator set, protecting the generator set from vibration damage to its own structure or components, and improving its service life.

[0021] Furthermore, the pusher plate divides the vacuum chamber into a first chamber and a second chamber, and both the first chamber and the second chamber are equipped with a one-way inlet valve and a one-way outlet valve.

[0022] To facilitate the intake and exhaust of gas as the push plate slides left and right inside the vacuum chamber, thus providing conditions for heat dissipation inside the chassis.

[0023] Furthermore, a controller is installed on the chassis, and an ultrasonic analyzer is installed on the generator set.

[0024] When a bearing wear fault occurs in the generator set, periodic impact vibrations are generated, which excite high-frequency ultrasonic waves. These waves are collected and analyzed by an ultrasonic analyzer, and the signals are then sent to the controller to trigger an alarm, thus realizing the self-diagnosis process of the generator set fault.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. This invention generates up-and-down vibrations during generator operation. When the generator moves downwards, on one hand, the support plate pushes the push rod, causing the sliding magnet to move downwards along the fixed box; on the other hand, the support plate pushes the impact rod downwards along the fixed cylinder and strikes the quartz block, generating a current that is detected by the controller. When the current generated by the quartz block is detected and fed into the controller, the controller changes the direction of the current flowing into the drive coil, starting the current into the drive coil at the left end of the guide post. When the impact rod pushes the straight rod, the straight rod pushes the folding plate to move to the left along the slide groove and compresses the damping spring for shock absorption. At this time, the folding plate moves to the left along the guide post, reducing the effective number of turns of the drive coil and lowering the resistance. This causes the current flowing into the second electromagnet through the folding plate to gradually increase, making the second electromagnet energized and exhibiting the same polarity as the sliding magnet, thereby resisting the downward-moving sliding magnet and reducing the moving distance of the sliding magnet. To reduce generator set vibration, as the generator set moves upward, the support plate drives the push rod and sliding magnet upward along the fixed box, while the support plate drives the impact rod upward along the fixed cylinder. At this time, the impact rod no longer strikes the quartz block, and the controller restores the current direction flowing into the drive coil, starting the current flow from the drive coil at the right end of the guide post. Under the action of the impact rod pulling the straight rod upward and the self-restoring force of the damping spring, the straight rod pushes the folding plate to move to the right along the slide groove. At this time, the folding plate slides to the right along the guide post, reducing the effective number of turns of the drive coil and lowering the resistance. This causes the current flowing into the first electromagnet through the folding plate to gradually increase, making the first electromagnet energized and exhibiting the same polarity as the sliding magnet. This resists the upward-moving sliding magnet, reduces the moving distance of the sliding magnet, and together reduces the vibration of the generator set, protecting the generator set and extending its service life.

[0027] 2. In this invention, when the folding plate moves to the left, the upper rack drives the gear to rotate counterclockwise around the bent rod, which in turn drives the lower rack to move to the right. At this time, the rack drives the slide plate to pull the push plate to the right, compressing the high-temperature gas in the second chamber of the vacuum chamber and expelling it through the one-way exhaust valve. Simultaneously, outside air is drawn into the first chamber through the one-way intake valve. When the folding plate moves to the right, the upper rack drives the gear to rotate clockwise around the bent rod, which in turn drives the lower rack to move to the left. At this time, the rack drives the slide plate to push the push plate to the left, compressing the gas in the first chamber of the vacuum chamber and delivering it to the air supply pipe through the one-way exhaust valve. Simultaneously, high-temperature air from inside the machine is drawn into the second chamber through the one-way intake valve. Gas enters and, in the gas supply pipe, is transported through the exhaust pipe to the straight pipe and discharged into the chassis for heat exchange. This heats the generator set inside the chassis, which generates high temperatures. Since different areas of the generator set generate different amounts of heat, in the high-temperature zone, when the temperature is too high, the memory spring contracts due to heat, thereby pulling the circular plate and driving the pull rope. This causes the extrusion block to move along the first and second fixed rings, extruding the straight pipe elastic tube and reducing the flow diameter at the straight pipe elastic tube. With the flow velocity in the exhaust pipe remaining constant, the smaller diameter at the straight pipe elastic tube increases the gas flow velocity, accelerates heat exchange in the high-temperature zone, and further improves the heat exchange rate in the high-temperature zone inside the chassis.

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0039] Example: Figures 1-9 As shown, the present invention provides a technical solution:

[0040] like Figure 1 , Figure 2 As shown, a generator set with fault self-diagnosis function includes a chassis 1, a generator set 2, a vibration damping unit 3 and a heat dissipation unit 4. The chassis 1 is placed on a horizontal ground. The generator set 2 is fixedly connected to the vibration damping unit 3. The vibration damping unit 3 has the function of reducing the vibration generated when the generator set 2 is working. The vibration damping unit 3 is fixedly connected to the heat dissipation unit 4. The heat dissipation unit 4 has the function of reducing the temperature inside the chassis 1.

[0041] The chassis 1 is used to install and fix the generator set 2, the vibration damping unit 3, and the heat dissipation unit 4. The generator set 2 is used to provide power. The vibration damping unit 3 is used to reduce the vibration generated by the generator set 2 when it is working. The heat dissipation unit 4 is used to dissipate the heat generated by the generator set 2 when it is working inside the chassis 1, thereby achieving cooling. When the generator set 2 is working inside the chassis 1, the vibration generated by the generator set 2 is reduced by the vibration damping unit 3 to avoid damage or loosening of the generator set 2 parts. The heat dissipation unit 4 dissipates the heat generated by the generator set 2 in a timely manner from the chassis 1 to avoid high temperature causing failure of the generator set 2.

[0042] like Figure 6 , Figure 8 As shown, the damping unit 3 includes a support plate 31, a striker 32, a quartz block 33, a fixed cylinder 34, a slide groove 35, a guide post 36, and a folding plate 37. The support plate 31 is fixedly connected to the generator set 2, the support plate 31 is fixedly connected to the striker 32, the striker 32 is slidably connected to the fixed cylinder 34, the quartz block 33 is fixedly installed inside the fixed cylinder 34, the fixed cylinder 34 is fixedly installed inside the housing 1, the slide groove 35 is fixedly installed inside the housing 1, one end of the guide post 36 is fixedly connected to the fixed cylinder 34, and the other end of the guide post 36 is slidably connected to the folding plate 37, which is slidably installed inside the slide groove 35.

[0043] like Figure 5 , Figure 6 , Figure 8 As shown, the shock absorption unit 3 also includes a shock absorption spring 38, a push rod 39, a first electromagnet 310, a second electromagnet 311, a sliding magnet 312, a fixed box 313, and a straight rod 314. One end of the shock absorption spring 38 is fixedly connected to the folding plate 37, and the other end of the shock absorption spring 38 is fixedly connected to the slide groove 35. One end of the push rod 39 is fixedly connected to the lower surface of the support plate 31, and the other end of the push rod 39 is fixedly connected to the sliding magnet 312. The push rod 39 is slidably connected to the first electromagnet 310. The first electromagnet 310 is fixedly installed in the upper part of the fixed box 313, and the second electromagnet 311 is fixedly installed in the lower part of the fixed box 313. The sliding magnet 312 is slidably installed in the fixed box 313. The fixed box 313 is fixedly installed in the chassis 1. One end of the straight rod 314 is rotatably connected to the impact rod 32, and the other end of the straight rod 314 is rotatably connected to the folding plate 37. The folding plate 37 is electrically connected to the first electromagnet 310 and the second electromagnet 311.

[0044] When generator set 2 is working, it vibrates up and down. When generator set 2 moves downward, on the one hand, the support plate 31 pushes the push rod 39 to drive the sliding magnet 312 to move downward along the fixed box 313. On the other hand, the support plate 31 pushes the impact rod 32 to move downward along the fixed cylinder 34 and strike the quartz block 33, generating current that is detected by the controller. When the current generated by the quartz block 33 is detected and enters the controller, the controller changes the direction of the current entering the drive coil, starting the current from the drive coil at the left end of the guide post 36. When the impact rod 32 pushes the straight rod 314, the straight rod 314 pushes the folding plate 37 to move to the left along the slide groove 35 and squeezes the shock-absorbing spring 38 to absorb shock. At this time, the folding plate 37 moves to the left along the guide post 36, the effective number of turns of the drive coil decreases, and the resistance decreases. As a result, the current flowing into the second electromagnet 311 through the folding plate 37 gradually increases, so that the second electromagnet 311 is energized and presents the same polarity as the sliding magnet 312, thereby resisting the downward moving sliding magnet 312, reducing the moving distance of the sliding magnet 312, and reducing the power generation. When generator set 2 moves upward, the vibration of generator set 2 is mitigated by the following: on the one hand, the support plate 31 drives the push rod 39 and the sliding magnet 312 to move upward along the fixed box 313; on the other hand, the support plate 31 drives the impact rod 32 to move upward along the fixed cylinder 34. At this time, the impact rod 32 no longer strikes the quartz block 33, and the controller restores the current direction to the drive coil. Current is then introduced into the drive coil from the right end of the guide post 36. Under the action of the impact rod 32 pulling the straight rod 314 upward in conjunction with the self-restoring force of the damping spring 38, the straight rod 314 pushes the folding plate 37 to move to the right along the slide groove 35. At this time, the folding plate 37 slides to the right along the guide post 36. The effective number of turns of the drive coil decreases, and the resistance decreases, thereby gradually increasing the current flowing into the first electromagnet 310 through the folding plate 37. This causes the first electromagnet 310 to be energized and exhibit the same polarity as the sliding magnet 312, thus resisting the upward movement of the sliding magnet 312, reducing the movement distance of the sliding magnet 312, and jointly reducing the vibration of generator set 2, protecting generator set 2, and improving the service life of generator set 2.

[0045] like Figure 3 , Figure 5 , Figure 7 , Figure 8 As shown, the heat dissipation unit 4 includes an upper rack 41, a gear 42, a bent rod 43, a lower rack 44, a vacuum box 45, and a push plate 46. The upper rack 41 is fixedly connected to the folding plate 37, the upper rack 41 is meshed with the gear 42, the gear 42 is rotatably connected to one end of the bent rod 43, the other end of the bent rod 43 is connected to the fixed wheel of the chassis 1, the gear 42 is meshed with the lower rack 44, the vacuum box 45 is fixedly connected to the chassis 1, and the push plate 46 is slidably installed inside the vacuum box 45.

[0046] like Figure 2 , Figure 9As shown, the heat dissipation unit 4 also includes an air supply pipe 47, an exhaust pipe 48, a straight pipe 49, a first fixing ring 410, a second fixing ring 411, and a pressing block 412. One end of the air supply pipe 47 is connected to the vacuum box 45, and the air supply pipe 47 is connected to the exhaust pipe 48. The exhaust pipe 48 is fixedly installed inside the chassis 1. The straight pipe 49 is connected to the exhaust pipe 48. The straight pipe 49 consists of rigid pipes at both ends and an elastic pipe in the middle. The first fixing ring 410 is fixedly installed at the rigid pipe of the straight pipe 49, and the second fixing ring 411 is fixedly installed at the rigid pipe of the straight pipe 49. The pressing block 412 is slidably installed between the first fixing ring 410 and the second fixing ring 411.

[0047] like Figure 5 , Figure 7 , Figure 9 As shown, the heat dissipation unit 4 also includes an elastic shrink ring 413, a pull rope 414, a circular plate 415, a memory spring 416, a fixing rod 417, and a sliding plate 418. The elastic shrink ring 413 is fixedly connected to the extrusion block 412. One end of the pull rope 414 is fixedly connected to the extrusion block 412, and the other end of the pull rope 414 passes through a straight tube 49 and is fixedly connected to the circular plate 415. One end of the memory spring 416 is fixedly connected to the circular plate 415, and the other end of the memory spring 416 is fixedly connected to the fixing rod 417. The fixing rod 417 is fixedly connected to the straight tube 49. One end of the sliding plate 418 is fixedly connected to the lower rack 44, and the other end of the sliding plate 418 is fixedly connected to the push plate 46. The sliding plate 418 is slidably connected to the vacuum box 45.

[0048] When the folding plate 37 moves to the left, the upper rack 41 drives the gear 42 to rotate counterclockwise around the bent rod 43. The gear 42 then drives the lower rack 44 to move to the right. At this time, the rack drives the sliding plate 418 to pull the push plate 46 to the right, compressing the high-temperature gas in the second chamber of the vacuum chamber 45 and discharging it through the one-way exhaust valve. Simultaneously, outside air is drawn into the first chamber through the one-way intake valve. When the folding plate 37 moves to the right, the upper rack 41 drives the gear 42 to rotate clockwise around the bent rod 43. The gear 42 then drives the lower rack 44 to move to the left. At this time, the rack drives the sliding plate 418 to push the push plate 46 to the left, compressing the gas in the first chamber of the vacuum chamber 45 and delivering it to the air supply pipe 47 through the one-way exhaust valve. Simultaneously, high-temperature gas is drawn into the second chamber through the one-way intake valve from inside the casing 1. The gas enters through the gas supply pipe 47 and is transported through the exhaust pipe 48 to the straight pipe 49 before being discharged into the chassis 1 for heat exchange. This heats the generator set 2 inside the chassis 1 to dissipate the high temperature generated during operation. Since different areas of the generator set 2 generate different amounts of heat, in the high-temperature zone, when the temperature is too high, the memory spring 416 contracts due to heat, thereby pulling the circular plate 415 and driving the pull rope 414. This causes the extrusion block 412 to move along the first fixed ring 410 and the second fixed ring 411, extruding the elastic tube of the straight pipe 49. This reduces the flow diameter at the elastic tube of the straight pipe 49. With the flow velocity in the exhaust pipe 48 remaining constant, the smaller diameter at the elastic tube of the straight pipe 49 increases the gas flow velocity, accelerates the heat exchange in the high-temperature zone, and further improves the heat exchange rate in the high-temperature zone inside the chassis 1.

[0049] like Figure 8 As shown, the ratio of the number of teeth of the upper rack 41 to the lower rack 44 is 3:1 to 9:1.

[0050] In order to convert the vertical displacement of the shock-absorbing support plate 31 into a small displacement of the upper rack 41 through the transmission of the straight rod 314, and then into a large displacement of the lower rack 44 under the transmission of the gear 42, so that the slide plate 418 can push the push plate 46 to draw in sufficient air from the outside or sufficient high-temperature gas from the chassis 1. During the left and right movement of the push plate 46, heat exchange is carried out inside the chassis 1, thereby improving the heat dissipation efficiency.

[0051] like Figure 6 As shown, a drive coil is provided on the guide post 36, and a conductive ring is provided at the contact end between the folding plate 37 and the guide post 36.

[0052] In order to facilitate the energization of the first electromagnet 310 and the second electromagnet 311 to suppress the movement amplitude of the sliding magnet 312, thereby reducing the vibration amplitude of the generator set 2, protecting the generator set 2 from vibration damage to its own structure or components, and improving its service life.

[0053] like Figure 5As shown, the pusher plate 46 divides the vacuum chamber 45 into a first chamber and a second chamber. Both the first chamber and the second chamber are equipped with a one-way inlet valve and a one-way outlet valve.

[0054] In order to facilitate the intake and exhaust of gas during the sliding motion of the push plate 46 in the vacuum chamber 45, and to provide conditions for heat dissipation inside the chassis 1.

[0055] like Figure 1 As shown, a controller is installed on the chassis 1, and an ultrasonic analyzer is installed on the generator set 2.

[0056] When a bearing wear fault occurs in generator set 2, periodic impact vibrations are generated, which excite high-frequency ultrasonic waves. These waves are collected and analyzed by an ultrasonic analyzer, and the signals are then sent to the controller to trigger an alarm, thus realizing the self-diagnosis process of the generator set fault.

[0057] Working principle of the invention:

[0058] When generator set 2 is working, it vibrates up and down. When generator set 2 moves downward, on the one hand, the support plate 31 pushes the push rod 39 to drive the sliding magnet 312 to move downward along the fixed box 313. On the other hand, the support plate 31 pushes the impact rod 32 to move downward along the fixed cylinder 34 and strike the quartz block 33, generating current that is detected by the controller. When the current generated by the quartz block 33 is detected and enters the controller, the controller changes the direction of the current entering the drive coil, starting the current from the drive coil at the left end of the guide post 36. When the impact rod 32 pushes the straight rod 314, the straight rod 314 pushes the folding plate 37 to move to the left along the slide groove 35 and squeezes the shock-absorbing spring 38 to absorb shock. At this time, the folding plate 37 moves to the left along the guide post 36, the effective number of turns of the drive coil decreases, and the resistance decreases. As a result, the current flowing into the second electromagnet 311 through the folding plate 37 gradually increases, so that the second electromagnet 311 is energized and presents the same polarity as the sliding magnet 312, thereby resisting the downward moving sliding magnet 312, reducing the moving distance of the sliding magnet 312, and reducing the power generation. When generator set 2 moves upward, the vibration of generator set 2 is mitigated by the following: on the one hand, the support plate 31 drives the push rod 39 and the sliding magnet 312 to move upward along the fixed box 313; on the other hand, the support plate 31 drives the impact rod 32 to move upward along the fixed cylinder 34. At this time, the impact rod 32 no longer strikes the quartz block 33, and the controller restores the current direction to the drive coil. Current is then introduced into the drive coil from the right end of the guide post 36. Under the action of the impact rod 32 pulling the straight rod 314 upward in conjunction with the self-restoring force of the damping spring 38, the straight rod 314 pushes the folding plate 37 to move to the right along the slide groove 35. At this time, the folding plate 37 slides to the right along the guide post 36. The effective number of turns of the drive coil decreases, and the resistance decreases, thereby gradually increasing the current flowing into the first electromagnet 310 through the folding plate 37. This causes the first electromagnet 310 to be energized and exhibit the same polarity as the sliding magnet 312, thus resisting the upward movement of the sliding magnet 312, reducing the movement distance of the sliding magnet 312, and jointly reducing the vibration of generator set 2, protecting generator set 2, and improving the service life of generator set 2.

[0059] When the folding plate 37 moves to the left, the upper rack 41 drives the gear 42 to rotate counterclockwise around the bent rod 43. The gear 42 then drives the lower rack 44 to move to the right. At this time, the rack drives the sliding plate 418 to pull the push plate 46 to the right, compressing the high-temperature gas in the second chamber of the vacuum chamber 45 and discharging it through the one-way exhaust valve. Simultaneously, outside air is drawn into the first chamber through the one-way intake valve. When the folding plate 37 moves to the right, the upper rack 41 drives the gear 42 to rotate clockwise around the bent rod 43. The gear 42 then drives the lower rack 44 to move to the left. At this time, the rack drives the sliding plate 418 to push the push plate 46 to the left, compressing the gas in the first chamber of the vacuum chamber 45 and delivering it to the air supply pipe 47 through the one-way exhaust valve. Simultaneously, high-temperature gas is drawn into the second chamber through the one-way intake valve from inside the casing 1. The gas enters through the gas supply pipe 47 and is transported through the exhaust pipe 48 to the straight pipe 49 before being discharged into the chassis 1 for heat exchange. This heats the generator set 2 inside the chassis 1 to dissipate the high temperature generated during operation. Since different areas of the generator set 2 generate different amounts of heat, in the high-temperature zone, when the temperature is too high, the memory spring 416 contracts due to heat, thereby pulling the circular plate 415 and driving the pull rope 414. This causes the extrusion block 412 to move along the first fixed ring 410 and the second fixed ring 411, extruding the elastic tube of the straight pipe 49. This reduces the flow diameter at the elastic tube of the straight pipe 49. With the flow velocity in the exhaust pipe 48 remaining constant, the smaller diameter at the elastic tube of the straight pipe 49 increases the gas flow velocity, accelerates the heat exchange in the high-temperature zone, and further improves the heat exchange rate in the high-temperature zone inside the chassis 1.

Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.

No reference numerals in the claims should be construed as limiting the scope of the claims.
