Description

Technical Field

[0001] The present invention relates to the technical field of switch cabinets, and in particular to an intelligent control device for a switch cabinet and a system thereof. Background Art

[0002] As power systems continue to evolve, switchgear faces increasingly complex operating environments and higher performance requirements. In industrial production, commercial buildings, and data centers, switchgear must operate reliably and long-term under harsh conditions such as high loads, high voltages, high temperatures, and high dust levels. Traditional switchgear heat dissipation, dust prevention, and maintenance methods struggle to meet these requirements. For example, high temperatures can easily cause insulation aging and increase contact resistance in electrical equipment, leading to failures. Dust accumulation can degrade insulation performance and cause short circuits. Traditional maintenance methods are time-consuming and labor-intensive, impacting the reliability and continuity of power supply.

[0003] Most traditional switchgear uses natural cooling or simple fans for cooling, which is inefficient and ineffective in removing internal heat, leading to localized overheating. Dust control measures often consist of a single air inlet filter, which has limited filtering effectiveness and requires regular manual cleaning and replacement. Otherwise, it can become clogged, impacting ventilation and cooling, accelerating equipment damage. Furthermore, for fire protection, traditional switchgear relies heavily on external firefighting equipment, resulting in a simple internal fire-retardant design.

Under the drive of 34, the two exhaust wheels 37 rotate, and the multiple rotating fan blades 38 stir the air flow inside the cabinet 2, making the internal gas temperature uniform. The two exhaust wheels 37 exhaust the air upward, so that the internal hot air is discharged through the exhaust duct 1 23 and the exhaust duct 2 24, and the internal negative pressure is generated, so that the external cold air enters the cabinet 2 through the outer groove 19 and the ventilation groove 21, thereby improving the heat dissipation and cooling efficiency inside the cabinet. In addition, the external air is filtered by the two front and rear filter screens 28 when entering, preventing dust from entering and corroding the internal switches and electrical equipment.

[0044] The outer frame 11 is fixed to the left and right sides of the outer surface of the casing 1, and the base 43 is fixed to the bottom of the casing 1.

When it is necessary to repair or disassemble the switchgear, the motor 44 is controlled to operate to rotate the screw rod 2 45, thereby raising the casing 1 through the screw block 46 and the outer frame 11 to expose the cabinet 2. At this time, the device is as shown in FIG. Figure 9 、 Figure 10 As shown, the interior of the cabinet 2 can be inspected through the opening that passes through the front and back of the cabinet 2, and the switching electrical equipment can be installed on the electrical rack 31.

[0045] The vertical cylinder 4 is slidably connected to a rotating rod 5, the top of the rotating rod 5 passes through the upper surface of the casing 1, and is fixed with a bevel gear 1 6. The left and right ends of the bevel gear 1 6 are meshed with the bevel gear 2 7. A rotating shaft 8 is fixed to the middle of the bevel gear 2 7. The outer surface of the rotating shaft 8 is rotatably connected to a bracket 10. The bottom of the bracket 10 is fixedly connected to the upper surface of the casing 1. A rectangular rod 51 is slidably connected to the inside of the rotating shaft 8. The end of the rectangular rod 51 away from the bevel gear 2 7 is fixed with a bevel gear 3 9. The bottom of the bevel gear 3 9 is meshed with a bevel gear 4 12. The bevel gear 4 12 is rotatably connected to the lower surface of the outer frame 11. A screw 13 is fixed to the bottom of the bevel gear 4 12. The bottom end of the screw 13 passes through the lower surface of the outer frame 11. The outer surface of the screw 13 is threadedly connected to the lifting frame 14, and a vacuum cleaner 15 is fixed to the outer surface of the lifting frame 14. The bottom of the vacuum cleaner 15 is connected to a suction pipe 17. A suction nozzle 16 is fixed to the lower surface of the lifting frame 14. The vacuum cleaner 15 is connected to the inside of the suction nozzle 16 through the suction pipe 17. The inner side of the lifting frame 14 is rotatably connected to the cleaning cylinder 18. A through guide groove 47 is opened on the front surface of the outer frame 11. A tooth plate 48 is fixed to the surface of the outer frame 11. A movable rod 49 is fixed to the middle of the cleaning cylinder 18. The front end of the movable rod 49 passes through the front of the guide groove 47 and is fixed with a transmission gear 50. The outer surface of the movable rod 49 is movably connected to the inside of the guide groove 47, and the transmission gear 50 is meshed with the tooth plate 48.

[0046] A coupling 52 is fixed to the side of the bevel gear three 9 away from the rectangular rod 51, and a bevel gear five 53 is fixed to the end of the coupling 52 away from the bevel gear three 9. The outer surface of the coupling 52 is rotatably connected to a slide 54, and the lower surface of the slide 54 is in contact with the upper surface of the housing 1. The front end of the slide 54 is threadedly connected to a screw rod 55. A worm gear 56 is fixed between the two screw rods 55. The front end of the worm gear 56 is threadedly connected to a worm 57. The bottom end of the worm 57 is fixedly connected to the upper surface of the spur gear two 41. The front end of the bracket one 10 is rotatably connected to the outer surface of the screw rod 55.

[0047] When the vertical cylinder 4 rotates, the rotating rod 5 inside it rotates accordingly and the two screw rods 13 are rotated through the sequential transmission of the bevel gear 1 6, the bevel gear 2 7, the rotating shaft 8, the rectangular rod 51, the bevel gear 3 9, and the bevel gear 4 12, so that the lifting frame 14 drives the vacuum cleaner 15, the suction nozzle 16, the suction pipe 17, and the cleaning cylinder 18 to move up and down. When the lifting frame 14 moves, the transmission gear 50 is meshed with the tooth plate 48 and rotates axially, which will drive the cleaning cylinder 18 to rotate. The cleaning cylinder 18 wipes the corresponding filter screen 2 28, and the vacuum cleaner 15 absorbs dust through the suction nozzle 16, thereby cleaning the filter screens 2 28 on both sides, so that when the four filter screens 28 are used alternately, the standby filter screen 28 can be cleaned and can be used after cleaning. The personnel control the timed automatic rotation and replacement of the filter screen 2 28 through the system. Clean and ready for use. When the filter screen 28 is controlled to operate or the vacuum cleaner 15, suction nozzle 16 and other cleaning equipment need to be controlled to move in the reverse direction, the rotating spur gear 2 41 drives the filter screen 28 to rotate, while the worm 57 rotates, and the two screw rods 55 are driven by the worm gear 56 to rotate axially, so that the slide 54 drives the bevel gear 3 9, the bevel gear 53, and the connecting shaft 52 to slide, so that the bevel gear 53 is meshed with the bevel gear 4 12. At this time, the direction of the screw 13 is changed, so that the vacuum cleaner 15 and suction nozzle 16 that have dropped to the bottom are raised; the arrangement of the bevel gear 5 53 and other structures can avoid the need to control the motor 13 to run in the reverse direction in order to make the vacuum cleaner 15 and suction nozzle 16 rise and reset, so that the wind wheel 37 rotates in the reverse direction to change its blowing direction, so that the external airflow enters through the filter screen 26, causing the filter screen 26 to perform a filtering operation.

[0048] Reference Figure 2-8 Filter 1 26 is located between exhaust duct 1 23 and exhaust duct 2 24, and the front and rear filter 2 28 are respectively between the front and rear outer grooves 19 and the ventilation groove 21. The front and rear filter 2 28 and the two filter 1 26 perform filtering operations. Filter 2 28 prevents dust from entering with the cold air flow when the air is incoming. Filter 1 26 prevents dust from naturally falling into the cabinet 2 when the device is not in operation.

[0049] Reference Figure 2-4 The top of the rotating rod 5 is a cylindrical structure, and the outer surface is rotatably connected to the casing 1. The bottom of the rotating rod 5 is located inside the vertical cylinder 4 and is a rectangular column structure. When the casing 1 rises, the rotating rod 5 will move with it and slide inside the vertical cylinder 4 while maintaining a rotational connection with the casing 1. The rectangular column structure allows the rotating rod 5 to rotate when the vertical cylinder 4 rotates.

[0050] Reference Figure 2-6 The outer surface of the rotating drum 27 is in contact with the inner surface of the interlayer 1 20, and the inner surface of the interlayer 22 is in contact with the outer surface of the turntable 25, ensuring that the rotating drum 27 is sealed against the vent groove 21 after rotation, and the turntable 25 is sealed against the exhaust duct.

[0051] Reference Figure 1-8 A second motor 39 is fixed below the outer surface of the casing 1, a third motor 40 is fixed in front of the upper surface of the casing 1, a second spur gear 41 is fixed to the top of the output shaft of the second motor 39, and a third spur gear 42 is fixed to the front end of the output shaft of the second spur gear 41;

[0052] The rear end of the spur gear 2 41 passes through the interior of the interlayer 1 20, and the outer surface of the bottom of the rotating drum 27 is provided with an annular tooth groove 1 29, and the rotating drum 27 is meshed with the spur gear 2 41 through the tooth groove 1 29; the bottom end of the spur gear 3 42 passes through the interior of the interlayer 22, and the outer surface of the turntable 25 is provided with a tooth groove 2 30, and the turntable 25 is meshed with the spur gear 3 42 through the tooth groove 2 30. When the motor 3 40 is running, the turntable 25 is driven by the spur gear 3 42 to rotate and adjust the position of the turntable 25 and the filter 1 26. When the motor 2 39 is operating, the rotating drum 27 and the four filter screens 28 can be rotated and adjusted 90 degrees through the spur gear 2 41, so that the cleaned filter screen 28 is moved to the ventilation groove 21 for filtering operation, and the filter screen 28 that has been filtering for a period of time is also moved to the outer frame 11 for cleaning operation; the rotating drum 27 can also be rotated 45 degrees so that the rotating drum 27 blocks the two ventilation grooves 21.

[0053] Reference Figure 2-3 The cleaning cylinder 18 is composed of two frustum structures. The cleaning cylinder 18 of the relative combination of the two frustums can make it closer to the filter screen 28 with an arc surface when it rotates. The outer surface of the cleaning cylinder 18 is provided with bristles, which can better clean the filter screen 28 through the cleaning cylinder 18. The suction nozzle 16 is provided with a rubber ring on the side close to the casing 1. The four rubber sheets form a ring frame structure that can better fit the surface of the arc-shaped filter screen 28, thereby providing a better negative pressure suction space for the vacuum cleaner 15 to absorb dust from the surface and filter holes of the filter screen 28 through the suction pipe 17 and the suction nozzle 16. The lifting frame 14 has a U-shaped structure. The outer surface of the lifting frame 14 fits with the inner surface of the outer frame 11. Under the fitting limit of the outer frame 11, when the screw 13 rotates, the lifting frame 14 can be stably lifted and lowered, and its U-shaped structure allows the cleaning cylinder 18 to rotate internally.

[0054] According to another aspect of the present invention, more specifically, an intelligent switchgear control system is provided, which uses an intelligent switchgear control device, including a control assembly 32; the control assembly 32 is internally provided with a data acquisition module, a switchgear control unit, a motor control unit, a communication module, and an alarm trigger unit;

[0055] The data acquisition module includes an electrical parameter acquisition unit, a switch status acquisition unit, and an environmental parameter acquisition unit;

[0056] The electrical parameter acquisition unit is mainly used to collect power parameters such as voltage, current, power factor, active power, and reactive power in the switchgear. It obtains voltage and current signals through voltage transformers and current transformers, and then amplifies and filters them through signal conditioning circuits to convert analog signals into digital signals for subsequent analysis and processing.

[0057] The switch status acquisition unit is responsible for collecting the opening and closing status of switchgear such as circuit breakers, disconnectors, and load switches in the switch cabinet; auxiliary contacts or sensors are usually used to detect the position status of the switches;

[0058] The environmental parameter acquisition unit includes a temperature sensor, a humidity sensor, and a gas sensor, which are used to monitor the ambient temperature, humidity, and harmful gas concentration parameters inside and outside the switch cabinet;

[0061] The alarm trigger unit determines whether an alarm needs to be triggered based on the preset alarm rules and the data obtained by the data acquisition module, and sends an alarm to the monitoring center.

[0062] When the gas sensor detects smoke inside the device, the temperature sensor detects high temperature, and the alarm trigger unit determines that a fire has occurred, the motor control unit will simultaneously control the operation of motor 2 39 and motor 3 40. Under the drive of spur gear 2 41, the rotary drum 27 rotates 45 degrees. At this time, the filter screen 28 is staggered with the ventilation groove 21, and the rotary drum 27 blocks the ventilation groove 21 so that it is no longer connected to the outer groove 19. At the same time, the turntable 25 rotates 90 degrees under the drive of spur gear 3 42.
