Description

Technical Field

[0001] This invention relates to the field of power distribution facilities, specifically to an intelligent multi-machine interconnection control cabinet for generators. Background Technology

[0002] The electrical energy generated by the generator is first collected at the busbar of the power distribution control cabinet. After the cabinet intelligently completes multi-machine joint control operations such as synchronous parallel operation, load sharing, power switching, and fault protection, the energy is then distributed to the electrical equipment through internal switches. The power distribution control cabinet is a core set of equipment supporting the operation of the smart grid industry, and mainly undertakes functions such as power distribution and regulation.

[0003] Currently, most power distribution control cabinets on the market rely on side wall cooling fans to provide overall cooling for the electrical components assembled from power electronic components inside the cabinet. However, the heat output of different electrical components varies significantly during equipment operation, and the overall cooling method is difficult to match the heat dissipation requirements of high-heat components. Insufficient heat dissipation can easily lead to localized overheating of components and poor cooling effect. Summary of the Invention

[0006] Preferably, the swing lifting component includes a stepped shaft disposed on the inner top surface of the power distribution control cabinet, a lifting rack is slidably installed through the interior of the large diameter section of the stepped shaft, the bent frame is fixed to the lower end of the lifting rack, and a swing gear is coaxially fixedly installed on the outer surface of the small diameter section of the stepped shaft, and a swing gear plate meshes with the upper part of the swing gear.

[0008] Preferably, guide bars extend from both sides of the lifting rack, and sliding grooves are provided through both sides of the large-diameter section of the stepped shaft. The guide bars slide through the interior of the sliding grooves, and a bearing seat is rotatably installed at the end of the small-diameter section of the stepped shaft. The upper end of the bearing seat is fixed to the inner top surface of the power distribution control cabinet.

[0009] Preferably, a servo motor is installed at the upper side edge of the power distribution control cabinet. A push shaft is coaxially fixedly installed at the output end of the servo motor. A push ear is fixedly installed at the end of the push shaft. A connecting push frame is rotatably installed at the end of the push ear. A connecting seat is rotatably installed at the end of the connecting push frame. A concave seat is fixedly installed on the side of the connecting seat. A lever is fixedly installed at the upper middle part of the swing tooth plate. The lever is elastically connected to the concave seat. The servo motor is connected to the controller.

[0010] Preferably, a motor frame is fixedly installed on the side of the first servo motor, the lower end of the first motor frame is fixed to the power distribution control cabinet, and a support frame is rotatably installed on the outer surface of the push shaft, the lower end of the support frame is fixed to the power distribution control cabinet.

[0011] Preferably, a square cavity is provided through the upper front edge of the power distribution control cabinet, and a slide is fixedly installed at the upper end of the power distribution control cabinet behind the square cavity. The concave seat slides through the end of the slide, and a sliding plate is fixedly installed between the two sides inside the square cavity. The lever is slidably installed on the outer surface of the sliding plate.

[0012] Preferably, a limiting post is fixedly installed between the two ends of the concave seat, the lever is slidably installed on the outer surface of the limiting post, and push plate springs are fixedly installed on both sides of the lever. The opposite ends of the two push plate springs are respectively fixed to the two ends of the concave seat, and the limiting post passes through the inside of the push plate spring.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. As a key piece of equipment in the smart grid industry, the power distribution control cabinet uses a swing-lift mechanism to move an infrared temperature sensor up and down within the cabinet. This allows the sensor to measure the temperature of all electrical components on the cabinet's rear panel. The controller reads the measured temperatures. When a temperature exceeds the limit, the controller stops the swing-lift mechanism, allowing the auxiliary cooling fan to stop in front of the overheated component. The auxiliary fan then operates under the controller's control to provide enhanced cooling for the overheated component. Once the temperature drops, the controller restarts the swing-lift mechanism, allowing the infrared temperature sensor to continue moving and measuring temperatures. This cycle repeats, ensuring that when a component in the power distribution control cabinet exceeds the temperature limit, enhanced cooling is provided to that component to prevent overheating of the electrical components assembled from power electronic components, thus improving cooling efficiency.

[0014] 2. The first servo motor drives the push ear on the push shaft to rotate, which in turn drives the connecting push frame to move, pushing the concave seat to slide back and forth. Then, through the push plate spring, the swing gear plate moves back and forth, causing the swing gear to rotate. This drives the stepped shaft to swing the lifting rack. During this process, the second servo motor drives the lifting gear to rotate, which in turn drives the lifting rack to rise and fall. This drives the infrared temperature probe to swing and rise and fall at the same time, so that the infrared temperature probe can move to the location of all electrical components on the back shell of the power distribution control cabinet for temperature measurement, thus ensuring the comprehensiveness of temperature measurement.

[0015] 3. During the process of the concave seat pushing the lifting rack to swing, the swing angle of the lifting rack will change as the lifting rack rises and falls. At this time, when the lifting rack swings and the rubber wheel on the extended top frame presses against the side wall of the power distribution control cabinet, the lifting rack will stop swinging due to the obstruction of the side wall of the power distribution control cabinet. At the same time, the swing plate stops moving, while the concave seat continues to move under the drive of the No. 1 servo motor until it reaches the end of the stroke. During this process, the push plate spring will deform to counteract the pushing force of the concave seat on the lifting rack when the lifting rack stops swinging, so that the movement of the two will not interfere with each other, thereby adapting to the different swing angles of the lifting rack.

Detailed Implementation

[0018] 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.

[0019] This invention provides a technical solution: such as Figures 1-8The diagram shows an intelligent multi-machine control cabinet for a generator, comprising a power distribution control cabinet 1. Main cooling fans 2 are installed through the lower parts of both sides of the power distribution control cabinet 1, serving as overall cooling units. A swing lifting component is installed on the top surface inside the power distribution control cabinet 1. A curved frame 6 is connected to the lower end of the swing lifting component, providing load-bearing support. A frame 9 is fixedly installed at one end of the curved frame 6, and an auxiliary cooling fan 4 is fixedly installed at the rear end of the frame 9, connecting the frame 9 and providing cooling for a small area. An infrared temperature probe 8 is installed behind the auxiliary cooling fan 4, fixed to the other end of the curved frame 6, serving as a temperature sensor. A controller 7 is fixedly installed at the upper end of the curved frame 6, connecting the auxiliary cooling fan 4 and the infrared temperature probe 8. Two protruding top frames 10 are symmetrically fixedly installed at the lower front end of the frame 9, with rubber wheels 11 connected to the ends of the protruding top frames 10, reducing the impact of the protruding top frames 10 on the power distribution control cabinet. The wear and tear between electrical control cabinets 1 is mitigated by a swing-lift mechanism that moves the infrared temperature probe 8 within the control cabinet 1, allowing it to measure the temperature of all electrical components on the rear shell of the control cabinet 1. Simultaneously, the controller 7 reads the measured temperatures. When a temperature exceeds the limit, the controller 7 issues a command to stop the swing-lift mechanism, allowing the auxiliary cooling fan 4 to remain in front of the overheated component. The auxiliary cooling fan 4 then operates under the control of the controller 7 to provide enhanced cooling for the overheated component. Once the temperature drops, the controller 7 resumes operation of the swing-lift mechanism, allowing the infrared temperature probe 8 to continue moving and measuring temperatures. This cycle repeats, ensuring that when a specific electrical component in the control cabinet 1 exceeds its temperature limit, enhanced cooling is provided for that component to prevent overheating of the electrical components assembled from power electronic components within the control cabinet 1, thereby improving the cooling effect.

[0020] The swing lifting component includes a stepped shaft 28 installed on the inner top surface of the power distribution control cabinet 1. A lifting rack 5 is slidably installed through the large diameter section of the stepped shaft 28. The stepped shaft 28 drives the lifting rack 5 to swing. The bent frame 6 is fixed to the lower end of the lifting rack 5. A swing gear 26 is coaxially fixed on the outer surface of the small diameter section of the stepped shaft 28. A swing gear plate 27 meshes with the upper part of the swing gear 26. The cooperation between the swing gear plate 27 and the swing gear 26 can drive the stepped shaft 28 to reciprocate.

[0021] A second motor frame 33 is fixedly mounted on the outer surface of the large-diameter section of the stepped shaft 28. A second servo motor 30 is fixedly mounted at the end of the second motor frame 33. The second motor frame 33 serves to fix the second servo motor 30. A lifting gear 29 is fixedly mounted coaxially at the output end of the second servo motor 30. The lifting gear 29 meshes with the lifting rack 5. The second servo motor 30 is connected to the controller 7. The second servo motor 30 drives the lifting gear 29 to rotate, thereby driving the lifting rack 5 to rise. However, when the lifting rack 5 rises to the end of its stroke, the second servo motor 30 drives the lifting gear 29 to rotate in the opposite direction, thereby driving the lifting rack 5 to descend. This process is repeated.

[0022] Guide bars 12 extend from both sides of the lifting rack 5. Slide grooves 32 are provided through both sides of the large diameter section of the stepped shaft 28. The cooperation between the guide bars 12 and the slide grooves 32 prevents the lifting rack 5 and the stepped shaft 28 from separating. The guide bars 12 slide through the interior of the slide grooves 32. A bearing seat 31 is rotatably installed at the end of the small diameter section of the stepped shaft 28. The upper end of the bearing seat 31 is fixed to the inner top surface of the power distribution control cabinet 1. The bearing seat 31 serves to support the stepped shaft 28.

[0023] A servo motor 3 is installed at the upper edge of the power distribution control cabinet 1. A push shaft 15 is coaxially fixedly installed at the output end of the servo motor 3. A push ear 16 is fixedly installed at the end of the push shaft 15. A connecting push frame 17 is rotatably installed at the end of the push ear 16. The push ear 16 drives the connecting push frame 17 to move. A connecting seat 25 is rotatably installed at the end of the connecting push frame 17. A concave seat 18 is fixedly installed on the side of the connecting seat 25. The connecting seat 25 facilitates the connection between the connecting push frame 17 and the concave seat 18. A lever 21 is fixedly installed at the middle of the upper end of the swing tooth plate 27. The lever 21 is elastically connected to the concave seat 18. The servo motor 3 and the controller... The 7-phase connection allows the first servo motor 3 to drive the push ear 16 on the push shaft 15 to rotate, thereby driving the connecting push frame 17 to move and push the concave seat 18 to slide back and forth. Then, through the push plate spring 22, the swing tooth plate 27 is pushed to move back and forth, causing the swing gear 26 to rotate. This drives the stepped shaft 28 to swing the lifting rack 5. During this process, the second servo motor 30 drives the lifting gear 29 to rotate, thereby driving the lifting rack 5 to rise and fall. This drives the infrared temperature probe 8 to swing and rise at the same time, so that the infrared temperature probe 8 can move to the location of all electrical components on the rear shell inside the power distribution control cabinet 1 for temperature measurement, thus ensuring the comprehensiveness of temperature measurement.

[0024] A motor bracket 13 is fixedly installed on the side of the servo motor 3. The lower end of the motor bracket 13 is fixed to the power distribution control cabinet 1. The motor bracket 13 serves to fix the servo motor 3. A support frame 14 is rotatably installed on the outer surface of the push shaft 15. The support frame 14 serves to support the push shaft 15. The lower end of the support frame 14 is fixed to the power distribution control cabinet 1.

[0025] A square cavity 19 is provided through the front edge of the upper end of the power distribution control cabinet 1. The square cavity 19 serves to prevent the lifting rack 5 from being obstructed during lifting. A slide 20 is fixedly installed at the upper end of the power distribution control cabinet 1 behind the square cavity 19. A concave seat 18 slides through the end of the slide 20. The slide 20 serves to guide the concave seat 18. A sliding plate 24 is fixedly installed between the two sides inside the square cavity 19. A lever 21 is slidably installed on the outer surface of the sliding plate 24. The sliding plate 24 serves to guide the lever 21.

[0026] A limiting post 23 is fixedly installed between the two ends of the concave seat 18. The lever 21 is slidably installed on the outer surface of the limiting post 23. Push springs 22 are fixedly installed on both sides of the lever 21. The limiting post 23 prevents the push springs 22 from bending. The opposite ends of the two push springs 22 are fixed to the two ends of the concave seat 18 respectively. The limiting post 23 passes through the inside of the push springs 22. During the process of the concave seat 18 pushing the lifting rack 5 to swing, the swing angle of the lifting rack 5 changes as the lifting rack 5 rises and falls. At this time, when the lifting rack... When the rubber wheel 11 extending from the top frame 10 is pressed against the side wall of the power distribution control cabinet 1, the lifting rack 5 will stop swinging due to the obstruction of the side wall of the power distribution control cabinet 1. At the same time, the swing tooth plate 27 will stop moving, while the concave seat 18 will continue to move under the drive of the first servo motor 3 until it reaches the end of the stroke. During this process, the push plate spring 22 will deform to counteract the pushing force of the concave seat 18 on the lifting rack 5 when the lifting rack 5 stops swinging, so that the movement of the two will not interfere with each other, thereby adapting to the different swing angles of the lifting rack 5.

[0027] As a key piece of equipment in the smart grid industry, the power distribution control cabinet 1 operates by having servo motor 3 drive the push lug 16 on the push shaft 15 to rotate, which in turn drives the connecting push frame 17 to move, causing the concave seat 18 to slide back and forth. This, in turn, pushes the swing gear plate 27 to move back and forth via the push plate spring 22, causing the swing gear 26 to rotate. This, in turn, drives the stepped shaft 28 to swing the lifting rack 5. During this process, servo motor 30 drives the lifting gear 29 to rotate, which in turn drives the lifting rack 5 to move up and down. This causes the infrared temperature sensor 8 to swing and move up and down simultaneously, allowing the infrared temperature sensor 8 to measure the temperature of all electrical components on the rear shell inside the power distribution control cabinet 1. At the same time, the controller 7 reads the measured temperature and detects when a temperature is detected. When the temperature exceeds the limit, the controller 7 will issue a command to stop the first servo motor 3 and the second servo motor 30, allowing the auxiliary cooling fan 4 to stop in front of the electrical component with the excessive temperature. Then, the auxiliary cooling fan 4 will run under the control of the controller 7 to strengthen the cooling of the electrical component with the excessive temperature. After the temperature drops, the controller 7 will control the first servo motor 3 and the second servo motor 30 to run again, allowing the infrared temperature probe 8 to continue moving to measure the temperature. This cycle is repeated so that when the temperature of a certain electrical component in the power distribution control cabinet 1 exceeds the limit, the cooling of the electrical component with the excessive temperature will be strengthened to prevent the electrical components inside the power distribution control cabinet 1, which are made and assembled from power electronic components, from overheating, thereby improving the cooling effect.
