Description

Technical Field

[0001] This invention relates to the field of switchgear, and more particularly to an intelligent integrated low-voltage switchgear. Background Technology

[0002] Low-voltage switchgear, as an important power distribution device in the power system, integrates a large number of electrical components such as circuit breakers, contactors, relays, and frequency converters. These components generate a significant amount of heat during operation. If this heat cannot be dissipated in time, the internal temperature of the switchgear will rise, directly affecting the operational reliability, insulation performance, and service life of the electrical components. In severe cases, it may lead to equipment failure or safety accidents. Therefore, the ventilation and heat dissipation design of the switchgear is a crucial aspect of its structural design.

[0003] Currently, common low-voltage switchgear typically has ventilation openings on its bottom, side walls, or doors, and is equipped with filters to prevent dust and debris from the outside air from entering the cabinet and causing short circuits in electrical components. However, in practical applications, existing switchgear ventilation and filtration systems have the following shortcomings: First, the maintenance and replacement of filters mainly rely on manual operation. Since switchgear typically operates continuously, filters are prone to clogging after prolonged use, requiring regular cleaning or replacement. However, switchgear is often installed in power distribution rooms, equipment rooms, or outdoor prefabricated substations, where space is limited and cabinets are densely packed. Manual filter replacement is not only inconvenient and inefficient, but also prone to severe clogging due to delayed maintenance, affecting airflow and consequently causing poor heat dissipation within the cabinet. Especially in dusty environments, filter clogging accelerates, significantly increasing the workload of frequent manual maintenance.

[0004] Secondly, existing switchgear filters are mostly fixed with screws or clips, making disassembly and installation cumbersome. When replacing filters, maintenance personnel need to loosen the fasteners one by one, remove the old filter, place the new filter, and retighten it, resulting in numerous steps and a long time consumption. For modular switchgear with multiple independent cabinets, the air inlet for each cabinet needs to be handled separately, multiplying the maintenance workload and making efficient and quick filter replacement difficult.

[0005] Third, the types and quantities of electrical components installed in different cabinets vary, resulting in significant differences in their heat generation. However, the ventilation structure of traditional switchgear typically consists of fixed openings or air inlets of uniform size, making it impossible to independently adjust the airflow according to the actual heat dissipation needs of each cabinet. This leads to insufficient ventilation and higher temperatures in some cabinets with high heat generation, while cabinets with low heat generation experience excessive airflow, resulting in uneven overall heat dissipation efficiency and an inability to achieve precise and differentiated airflow control.

[0006] Therefore, in response to the problems of existing low-voltage switchgear's ventilation and filtration systems, such as the reliance on manual replacement of filters, cumbersome operation, low maintenance efficiency, and the inability to independently adjust the ventilation volume according to the actual heat demand of each cabinet, there is an urgent need to provide an intelligent integrated low-voltage switchgear that can automatically replace and clamp and release filters, and has independent airflow control function for each cabinet, so as to improve the automation level and ventilation and heat dissipation performance of the switchgear.

[0023] To make the technical problems, technical solutions and advantages of the present invention clearer, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0024] according to Figures 1-10As shown, an intelligent integrated low-voltage switchgear includes a filter fastener, a filter replacement component, and an airflow control component. The filter fastener is on the switchgear 40 and is used to stably clamp the filter screen 1 of the filter replacement component to filter the air entering the switchgear 40. The filter replacement component automatically replaces the filter screen 1 on the filter fastener. The airflow control component is on the switchgear 40 and is used to regulate the ventilation volume of each cabinet in the switchgear 40.

[0025] The filter fastener includes a protective shell and an automatic fastener. The protective shell is on the switch cabinet 40 and provides support for the automatic fastener. The automatic fastener is on the protective shell and automatically clamps the filter screen 1 at the air inlet on the protective shell to filter the air entering the switch cabinet 40.

[0026] The protective shell includes a front protective shell 2, a rear protective shell 3, a left protective shell 4, a right protective shell 5, and a bottom end face 6. The upper side of the front protective shell 2 is sealed to the front side of the bottom surface of the switch cabinet 40. The upper side of the rear protective shell 3 is sealed to the rear side of the bottom surface of the switch cabinet 40. The upper side of the left protective shell 4 is sealed to the left side of the bottom surface of the switch cabinet 40. The upper side of the right protective shell 5 is sealed to the right side of the bottom surface of the switch cabinet 40. The connecting ends of the front protective shell 2, the rear protective shell 3, the left protective shell 4, and the right protective shell 5 are sealed together. The bottom end face 6 is fixedly disposed on the lower side of the front protective shell 2, the rear protective shell 3, the left protective shell 4, and the right protective shell 5. At the same time, the bottom end face 6 provides support for the legs of the switch cabinet 40.

[0027] Furthermore, the front protective shell 2 is provided with five first air inlets 7 for ventilation and heat dissipation, and the five first air inlets 7 are respectively located below the five cabinets of the switch cabinet 40. The rear protective shell 3 is provided with five second air inlets 8 for ventilation and heat dissipation, and the five second air inlets 8 are respectively located below the five cabinets of the switch cabinet 40. The left protective shell 4 is provided with one third air inlet 9 for ventilation and heat dissipation, and the third air inlet 9 is located on the left side of the switch cabinet 40. The right protective shell 5 is provided with one fourth air inlet 10 for ventilation and heat dissipation, and the fourth air inlet 10 is located on the right side of the switch cabinet 40.

[0028] The automatic fastener includes an automatic clamping component, a release transmission component, and a first power component. The automatic clamping component is used to clamp the filter screen 1 on the protective shell. The release transmission component is on the protective shell and transmits the driving force of the first power component to the automatic clamping component, thereby providing power for the automatic clamping component to change from the state of clamping the filter screen 1 to the state of releasing the filter screen 1.

[0029] The automatic clamping mechanism includes a first clamping member 11, a second clamping member 12, a third clamping member 13, and a fourth clamping member 14. The first clamping member 11 clamps the filter screen 1 on the front protective shell 2 to filter the air entering the protective shell. The second clamping member 12 clamps the filter screen 1 on the rear protective shell 3 to filter the air entering the protective shell. The third clamping member 13 clamps the filter screen 1 on the left protective shell 4 to filter the air entering the protective shell. The fourth clamping member 14 clamps the filter screen 1 on the right protective shell 5 to filter the air entering the protective shell.

[0030] The first clamping member 11 includes a panel 15, a clamping plate 16, a guide rod 17, a spring 18, and a nut 19. The panel 15 is fastened to the front protective shell 2, and the panel 15 has a cutout corresponding to the first air inlet 7 to facilitate the passage of external air. One end of the guide rod 17 is fixed to the front protective shell 2 to guide the sliding clamping of the clamping plate 16. The clamping plate 16 has a sliding hole, and the clamping plate 16 is slidably fitted onto the guide rod 17 through the sliding hole, so that the cutout of the clamping plate 16 corresponds to the cutout of the panel 15. The clamping plate 16 and the panel 15 are used to clamp the filter screen 1. The spring 18 is sleeved on the guide rod 17, and the nut 19 is fitted onto the external thread on the other end of the guide rod 17. The nut 19, through the spring 18, presses the clamping plate 16 to apply a clamping force to the panel 15, so as to stably clamp the filter screen 1 on the surface. The pressure on the spring 18 is adjusted by adjusting the length of the screw-in nut 19, thereby adjusting the clamping force of the clamping plate 16 on the filter screen 1.

[0031] Alternatively, six guide rods 17 are provided, with three guide rods 17 evenly spaced longitudinally above the panel 15 and three guide rods 17 evenly spaced longitudinally below the panel 15. Six sliding holes on the clamping plate 16 correspond one-to-one with the six guide rods 17. Guide tubes 20 are embedded within the sliding holes, and the sliding holes are axially slidably fitted onto the guide rods 17 through the guide tubes 20.

[0032] Five sets of the first clamping members 11 are provided, each corresponding to one of the five first air inlets 7. It should be noted that, due to the large size of the switch cabinet 40, its width is relatively long. Providing five air inlets significantly reduces the length of a single clamping plate 16, thereby reducing the longitudinal deformation of the clamping plate 16 pressing against the panel 15, and also reducing the longitudinal deformation when the clamping plate 16 is pulled outward by the release transmission member to release the filter screen 1. It also reduces the thickness of the clamping plate 16, thus lowering its strength requirements.

[0033] The second clamping member 12 has the same structure as the first clamping member 11. The second clamping member 12 is disposed on the rear protective shell 3 and is used to clamp the filter screen 1. Five sets of the second clamping member 12 are provided, and each of the five sets of the second clamping member 12 corresponds to one of the five second air inlets 8. It is used to filter the air entering the protective shell through the second air inlets 8.

[0034] The third clamping member 13 has the same structure as the first clamping member 11. The third clamping member 13 is disposed on the left protective shell 4 and is used to clamp the filter screen 1. The third clamping member 13 corresponds to the third air inlet 9. The fourth clamping member 14 has the same structure as the first clamping member 11. The fourth clamping member 14 is disposed on the right protective shell 5 and is used to clamp the filter screen 1. The fourth clamping member 14 corresponds to the fourth air inlet 10. It is used to filter the air entering the protective shell.

[0035] The release transmission components include a first transmission component 21, a second transmission component 22, a third transmission component 23, and a fourth transmission component 24. The first transmission component 21, on the protective shell, drives the first clamping component 11 connected thereto, thereby pulling the clamping plate 16 of the first clamping component 11 outward to release the filter screen 1. The second transmission component 22, on the protective shell, drives the second clamping component 12 connected thereto, thereby pulling the clamping plate 16 of the second clamping component 12 outward to release the filter screen 1. The third transmission component 23, on the protective shell, drives the third clamping component 13 connected thereto, thereby pulling the clamping plate 16 of the third clamping component 13 outward to release the filter screen 1. The fourth transmission component 24, on the protective shell, drives the fourth clamping component 14 connected thereto, thereby pulling the clamping plate 16 of the fourth clamping component 14 outward to release the filter screen 1.

[0036] The first transmission component 21 includes a transmission rod 25, a first gear 26, a rack 27, and a bevel gear 28. The transmission rod 25 is rotatably mounted on the front side of the bottom end face 6 via a rotating support frame, allowing the transmission rod 25 to rotate on the bottom end face 6. The first gear 26 is fixedly mounted on the transmission rod 25 and moves with it. One end of the rack 27 is vertically fixedly connected to the clamping plate 16 of the first clamping component 11, and the rack 27 meshes with the first gear 26. The bevel gear 28 is correspondingly disposed at the end of the transmission rod 25 and is used to mesh with the third transmission component 23 and the fourth transmission component 24 for transmission.

[0037] When the transmission rod 25 is driven to rotate forward by the first power component, it will drive the first gear 26 to rotate. The forward-rotating first gear 26 will pull the rack 27 outward, causing the clamping plate 16 to move outward. The outward-moving clamping plate 16 releases the filter screen 1, making it easier for the filter replacement component to collect the old, clogged filter screen 1 and transfer the new filter screen 1 to the first air inlet 7. When the transmission rod 25 is driven to rotate in the opposite direction by the first power component, it will push the rack 27 inward through the first gear 26. In turn, the rack 27 will push the clamping plate 16 to press the new filter screen 1 onto the panel 15. The continuous pressure of the spring 18 prevents the filter screen 1 from loosening due to vibrations generated during the filtration process.

[0038] Furthermore, five first gears 26 are provided, each corresponding to one of the five sets of first clamping members 11. Five racks 27 are provided, each connected to one of the clamping plates 16 of the five sets of first clamping members 11, and each rack 27 meshes with one of the five first gears 26. Two bevel gears 28 are respectively disposed at both ends of the transmission rod 25, and each bevel gear 28 meshes with the third transmission member 23 and the fourth transmission member 24 for transmission.

[0039] The second transmission member 22 has the same structure as the first transmission member 21. The second transmission member 22 is rotatably mounted on the rear side of the bottom end surface 6, allowing the transmission rod 25 of the second transmission member 22 to rotate on the bottom end surface 6. The second transmission member 22 is connected to the second clamping member 12 and is used to drive the clamping plate 16 of the second clamping member 12 to release the filter screen 1 outward. Five sets of the second transmission member 22 are provided, and the five sets of the second transmission member 22 are connected to the five sets of the second clamping member 12 in a corresponding manner.

[0040] The third transmission member 23 has the same structure as the first transmission member 21. The third transmission member 23 is rotatably mounted on the left side of the bottom end face 6, allowing the transmission rod 25 of the third transmission member 23 to rotate on the bottom end face 6. The transmission rod 25 of the third transmission member 23 is driven by the bevel gear of the third transmission member 23 meshing with the bevel gear of the first transmission member 21. The third transmission member 23 is connected to the third clamping member 13 and is used to drive the clamping plate 16 of the third clamping member 13 to release the filter screen 1 outward.

[0041] The fourth transmission member 24 has the same structure as the first transmission member 21. The fourth transmission member 24 is rotatably mounted on the right side of the bottom end face 6, allowing the transmission rod 25 of the fourth transmission member 24 to rotate on the bottom end face 6. The transmission rod 25 of the fourth transmission member 24 is connected to the bevel gears of the first transmission member 21 and the second transmission member 22 respectively via bevel gears at both ends of the fourth transmission member 24, which mesh with each other. The fourth transmission member 24 is connected to the fourth clamping member 14 and is used to drive the clamping plate 16 of the fourth clamping member 14 to release the filter screen 1 outward.

[0042] The first power component includes a first motor 29, a first worm gear 30, and a first worm wheel 31. The first motor 29 is fixedly mounted on the bottom end face 6. The first worm gear 30 is mounted on the shaft of the first motor 29. The first worm wheel 31 is fixedly mounted on the transmission rod 25 and meshes with the first worm gear 30. When the first motor 29 drives the transmission rod 25 of the first transmission component 21 to rotate via the first worm gear 30 and the first worm wheel 31, the transmission rod 25 of the first transmission component 21 simultaneously drives the transmission rods 25 of the third transmission component 23, the fourth transmission component 24, and the second transmission component 22 to rotate via bevel gears. This, in turn, drives the correspondingly connected clamping plate 16 to release the filter screen 1, thus enabling the filter replacement component to automatically replace the filter screen 1.

[0043] The filter replacement component includes a release component, a collection component 41, and a filter screen 1. The release component is rotatably mounted on the protective shell and is used to release a new filter screen 1 that is wound up. The collection component 41 is rotatably mounted on the protective shell and is used to wind up and collect the clogged filter screen 1. One end of the filter screen 1 is connected and wound around the release component, and the other end of the filter screen 1 passes through the third clamping component 13, the first clamping component 11, the fourth clamping component 14, and the second clamping component 12 in succession before being wound and connected to the collection component 41. When it is necessary to replace the clogged filter screen 1, firstly, pull the clamping plates 16 of the first clamping member 11, the second clamping member 12, the third clamping member 13, and the fourth clamping member 14 outward to release the clamped filter screen 1. Then, rotate the collecting member 41 in the forward direction to release the wound new filter screen 1, and simultaneously rotate the collecting member 41 in the reverse direction to wind up the clogged old filter screen 1. Continue until all the filter screens 1 in the first clamping member 11, the second clamping member 12, the third clamping member 13, and the fourth clamping member 14 have been moved and replaced with new filter screens 1. Then, the releasing member and the collecting member 41 stop rotating. Finally, re-clamp the first clamping member 11, the second clamping member 12, the third clamping member 13, and the fourth clamping member 14 to complete the automatic replacement of the filter screen 1.

[0044] The release component includes a rotating base 32, a rotating tube 33, a gear ring, a second gear, and a second motor 34. One end of the rotating base 32 is disposed on the bottom end face 6. One end of the rotating tube 33 is fitted onto the rotating base 32, allowing the rotating tube 33 to rotate circumferentially on the rotating base 32. The gear ring is fixedly embedded in the inner wall of the other end of the rotating tube 33. The second motor 34 is fixedly disposed on the bottom end face 6 inside the rotating base 32. The second gear is fixedly disposed on the rotating shaft of the second motor 34, and the second gear meshes with the gear ring.

[0045] Furthermore, the rotating seat 32 is tubular, the inner diameter of the rotating tube 33 is not less than the outer diameter of the rotating seat 32, and the length of the rotating tube 33 is greater than the length of the rotating seat 32. Alternatively, a bearing is provided between the rotating tube 33 and the rotating seat 32. The gear ring is an internal gear ring. One end of the filter screen 1 is connected to the outer wall of the rotating tube 33.

[0046] The collecting component 41 has the same structure as the releasing component. The collecting component 41 is disposed on the bottom end face 6, and the outer wall of the rotating tube of the collecting component 41 is connected to the other end of the filter screen 1 for rotating and winding to collect the clogged filter screen 1.

[0047] The filter screen 1, guided by the first guide shaft, first passes between the panel 15 and the clamping plate 16 of the third clamping member 13. Then, the other end of the filter screen 1, guided by the second guide shaft 36, passes between the panel 15 and the clamping plate 16 of the first clamping member 11. Next, the other end of the filter screen 1, guided by the third guide shaft 37, passes again between the panel 15 and the clamping plate 16 of the fourth clamping member 14. Then, the other end of the filter screen 1, guided by the fourth guide shaft 38, finally passes between the panel 15 and the clamping plate 16 of the second clamping member 12. Finally, the other end of the filter screen 1, guided by the fifth guide shaft 39, is connected to the outer wall of the rotating tube of the collecting member 41.

The first airflow control component is on the switch cabinet 40 and is used to control the airflow entering the first cabinet of the switch cabinet 40 from the protective shell. The second airflow control component is on the switch cabinet 40 and is used to control the airflow entering the second cabinet of the switch cabinet 40 from the protective shell. The third airflow control component is on the switch cabinet 40 and is used to control the airflow entering the third cabinet of the switch cabinet 40 from the protective shell. The fourth airflow control component is on the switch cabinet 40 and is used to control the airflow entering the fourth cabinet of the switch cabinet 40 from the protective shell. The fifth airflow control component is on the switch cabinet 40 and is used to control the airflow entering the fifth cabinet of the switch cabinet 40 from the protective shell.

[0049] The first airflow control component includes a baffle plate and a linear actuator. The baffle plate is slidably embedded in a groove on the bottom surface of the first cabinet to block the first ventilation hole on the bottom surface of the first cabinet. The bottom side wall of the linear actuator is fixedly installed on the bottom surface of the switch cabinet 40. The top of the linear actuator is connected to the baffle plate. When the linear actuator retracts, it will pull the baffle plate to one side to control the number of the first ventilation holes open, thereby controlling the airflow entering the first cabinet and allowing the air inside the protective shell to enter the first cabinet for ventilation and heat dissipation through the open first ventilation holes.

[0050] The slide rail is shaped like a right-angled plate, and there are two slide rails. One slide rail is vertically fixed to the bottom surface of the first cabinet on one side of the first ventilation hole, and the other slide rail is vertically fixed to the bottom surface of the first cabinet on the other side of the first ventilation hole. The two sides of the baffle plate are slidably fitted into the other right-angled surface of the two slide rails to accommodate multiple openings of the first ventilation holes.

[0051] The second airflow control component has the same structure as the first airflow control component. It is disposed on the bottom surface of the second cabinet and controls the number of open second ventilation holes on the bottom surface of the second cabinet, thereby controlling the airflow entering the second cabinet. This allows air from inside the protective shell to enter the second cabinet through the open second ventilation holes for ventilation and heat dissipation. The third airflow control component has the same structure as the first airflow control component and is disposed on the bottom surface of the third cabinet. It controls the number of open third ventilation holes on the bottom surface of the third cabinet, thereby controlling the airflow entering the third cabinet. This allows air from inside the protective shell to enter the third cabinet through the open third ventilation holes for ventilation and heat dissipation. The fourth airflow control component has the same structure as the first airflow control component and is disposed on the bottom surface of the fourth cabinet. It controls the number of open fourth ventilation holes on the bottom surface of the fourth cabinet, thereby controlling the airflow entering the fourth cabinet. This allows air from inside the protective shell to enter the fourth cabinet through the open fourth ventilation holes for ventilation and heat dissipation. The fifth air volume control component has the same structure as the first air volume control component. The fifth air volume control component is disposed on the bottom surface of the fifth cabinet and is used to control the number of the fifth ventilation holes on the bottom surface of the fifth cabinet to open, thereby controlling the air volume entering the fifth cabinet, so that the air inside the protective shell enters the fifth cabinet through the open fifth ventilation holes for ventilation and heat dissipation.

[0052] It should be noted that, since the types and quantities of electrical components installed in the first, second, third, fourth, and fifth cabinets are different, the heat generated in each cabinet is different. By adjusting the ventilation and heat dissipation airflow of each cabinet, each cabinet can be controlled at a reasonable temperature, thereby optimizing the overall ventilation and heat dissipation performance of the switch cabinet 40.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
