During normal operation, the circuit can be connected or disconnected with the help of manual or automatic switches. In the event of a fault or abnormal operation, the circuit can be cut off or an alarm can be issued with the help of protective electrical appliances.

[0003] During the use of the control cabinet, the components inside it will generate heat due to long-term operation. At this time, the control cabinet needs to be cooled. Generally, the heat dissipation of the control cabinet is discharged to the outside by installing a cooling fan. However, due to the large overall size of the control cabinet and the different sizes of various electrical components, when the fan is operating, the heat around the electrical components close to the fan will dissipate faster, while the air flow at a distance from the fan is poor due to the influence of wind, which will cause uneven heat dissipation inside the control cabinet, thereby affecting the heat dissipation effect.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting the disconnecting air guide, when the servo motor is powered on, the connecting sleeve moves up and down along the reciprocating screw rod. When the electromagnet is powered on, the magnetic block moves away from the electromagnet. When the latch is aligned with the locking hole, the latch will be inserted into the locking hole under the action of the elastic restoring force of the first telescopic spring. At this time, when the connecting sleeve moves, it will drive the trapezoidal block to move synchronously through the latch, so that the air intake pipe can extract air from different positions in the cabinet to ensure the uniformity of heat dissipation inside the cabinet. When the cabinet door is opened, the electromagnet and the servo motor are powered off to make the trapezoidal block lose connection with the connecting sleeve, so that the slider and the suction pipe are always at the inner bottom of the cabinet after the cabinet door is opened. This can prevent the slider and the suction pipe from blocking the components inside the cabinet and affecting the maintenance operation of the cabinet by the staff; 2. By setting a flow-increasing jet part, when the slider moves with the connecting sleeve, the transmission coupling moves synchronously with the slider, and the spur gear will rotate along the spur rack. When the spur gear rotates, it drives the rotating disk to rotate, so that the squeeze pin drives the direct-connected guide rail limited by the limiting plug rod and the slider to reciprocate in the horizontal direction. When the direct-connected guide rail moves toward the air bin, the connecting block squeezes the oblique connecting rod, so that the T-shaped card plate moves away from the air bin. At this time, the space between the two plug plates inside the air bin increases, so that the air inside the cabinet enters the inside of the air bin through the arc-shaped air pipe and the air guide hole. Similarly, when the direct-connected guide rail moves away from the air bin, the plug plate squeezes the air between the plug plates out of the air bin, and the impact of the air ejected from the arc-shaped air pipe on the air inside the cabinet improves the fluidity of the air inside the cabinet, further enhancing the heat dissipation effect of the equipment. 3. By setting a touch control unit, when the cabinet door is closed, the blocking rod will be pressed. At this time, the blocking rod will drive the first contact piece to move toward the second contact piece, so that the first contact piece contacts the second contact piece, and the third telescopic spring is stretched at the same time, so that the electromagnet and the servo motor are powered on. Similarly, when the cabinet door is opened, the blocking rod loses its cover and moves under the action of the elastic restoring force of the third telescopic spring, so that the second contact piece is separated from the first contact piece, thereby cutting off the power to the electromagnet and the servo motor, so as to control the operation timing of the electromagnet and the servo motor.

[0021] In this embodiment, the heat dissipation fan 4 is started and the cabinet door 2 is closed. As the cabinet door 2 is closed, the control unit controls the disconnecting air guide member to operate, so that the suction pipe 508 draws air from different positions in the cabinet 1, and then discharges the air from the cabinet 1 through the operation of the heat dissipation fan 4. In this process, the flow-increasing jet member operates synchronously with the disconnecting air guide member. The operation of the flow-increasing jet member increases the fluidity of the air inside the cabinet 1, thereby further improving the heat dissipation efficiency of the cabinet 1.

[0022] Example 2, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8The disconnecting air guide comprises a servo motor 502 installed at the bottom of the side connecting bin 501, the output end of the servo motor 502 is connected to a reciprocating screw rod 511 located on the inner side of the side connecting bin 501, a connecting sleeve block 512 is movably sleeved on the reciprocating screw rod 511, a sleeve 513 is installed on the side of the connecting sleeve block 512 close to the cabinet 1, an electromagnet 520 is installed on the inner wall of the sleeve 513, a push rod 517 penetrating to the outside of the sleeve 513 is inserted into the inside of the sleeve 513, a magnetic block 519 located on the inner side of the sleeve 513 is installed at one end of the push rod 517, a second telescopic spring 518 connected to the inner wall of the sleeve 513 is installed at the end of the magnetic block 519 away from the electromagnet 520, the second telescopic spring 518 is located on the outer side of the push rod 517, A push plate 514 is installed at one end of the rod 517 away from the magnetic block 519, and latches 515 are inserted at both ends of the push plate 514. A first telescopic spring 516 connected to the latch 515 is arranged on the side of the push plate 514 close to the sleeve 513. A positioning guide rod 505 flush with the side connecting bin 501 is arranged on the inner wall of the cabinet 1. A slider 507 is movably sleeved on the positioning guide rod 505. An air intake pipe 508 is installed on one side of the slider 507. An air bleed hose 504 connected to the air intake pipe 508 is arranged at the bottom of the heat dissipation fan 4. A trapezoidal block 506 is installed on the side of the slider 507 close to the side connecting bin 501. A locking hole 509 is opened on the side of the trapezoidal block 506 away from the slider 507, and a counterweight block 510 is arranged at the bottom of the slider 507. The two sides of the connecting sleeve 512 are in contact with the inner wall of the side connecting bin 501, and a crescent pin matching the outer side of the reciprocating screw 511 is arranged inside the connecting sleeve 512. By setting this structure, when the reciprocating screw 511 rotates, the connecting sleeve 512 moves up and down along the reciprocating screw 511; The end of the latch 515 away from the sleeve 513 is rotatably connected to a ball through a rotating shaft. The diameter of the locking hole 509 is equal to that of the latch 515. This structure is provided to reduce the friction between the latch 515 and the trapezoidal block 506, and also improve the stability of the connection between the trapezoidal block 506 and the connecting sleeve block 512 when the latch 515 is inserted into the locking hole 509. There are four positioning guide rods 505, which are evenly divided into two groups. The two groups of positioning guide rods 505 are symmetrically arranged along the vertical center axis of the cabinet 1. This structure is used to improve the stability of the vertical movement of the slider 507 and the suction pipe 508. In this embodiment, when the cabinet door 2 is closed, the servo motor 502 and the electromagnet 520 are powered on through the contact control unit. When the servo motor 502 is powered on, the reciprocating screw 511 is driven to rotate. When the reciprocating screw 511 rotates, the connecting sleeve 512 moves up and down along the reciprocating screw 511. When the electromagnet 520 is powered on, the magnetic block 519 moves away from the electromagnet 520 under the repulsive force of the electromagnet 520, and the second telescopic spring 518 contracts, thereby The end of the latch 515 away from the sleeve 513 is moved to a position flush with the side of the trapezoidal block 506 close to the slider 507. As the connecting sleeve 512 moves, the latch 515 contacts the trapezoidal block 506. At this time, the inclined surface of the trapezoidal block 506 guides the latch 515 relative to the push plate 514, so that the latch 515 moves toward the sleeve 513. At the same time, the first telescopic spring 516 stretches. When the latch 515 is aligned with the locking hole 509, the latch 515 is in contact with the trapezoidal block 506 under the action of the elastic restoring force of the first telescopic spring 516. When the connecting sleeve 512 is moved, the trapezoidal block 506 is driven to move synchronously through the latch 515, so that the position of the suction pipe 508 is changed, so that the suction pipe 508 can extract air from different positions in the cabinet 1, so as to ensure the uniformity of heat dissipation inside the cabinet 1. When the cabinet door 2 is opened, the electromagnet 520 and the servo motor 502 are powered off under the action of the touch control unit. At this time, the magnetic suction block 519 is connected to the electromagnetic under the action of the elastic restoring force of the second telescopic spring 518. The iron 520 fits together, so that the push plate 514 drives the pin 515 to move toward the sleeve 513, so that the pin 515 can be pulled out of the locking hole 509, so that the trapezoidal block 506 and the connecting sleeve block 512 lose connection, and the slider 507 will fall under the action of the counterweight block 510, so that after the cabinet door 2 is opened, the slider 507 and the suction pipe 508 are always at the inner bottom of the cabinet body 1, so as to prevent the slider 507 and the suction pipe 508 from blocking the components inside the cabinet body 1 and affecting the maintenance operation of the cabinet body 1 by the staff.

[0023] Example 3, please refer to Figure 2 , Figure 3 , Figure 4 , Figure 5The flow-increasing jet component includes a mounting seat 607 mounted on one side of the slider 507, and one end of the mounting seat 607 away from the suction pipe 508 is rotatably connected to a transmission shaft 612 through a bearing, and a rotating disk 610 is mounted on one end of the transmission shaft 612. A spur gear 613 located between the mounting seat 607 and the rotating disk 610 is arranged on the transmission shaft 612, and a spur rack 601 meshing with the spur gear 613 is installed on the inner wall of the cabinet 1, and an extrusion connecting pin 609 is installed on one end of the rotating disk 610, and a direct-connected guide rail 608 is sleeved on the extrusion connecting pin 609, and the outer wall of the direct-connected guide rail 608 is provided with a limiter slidably connected to the slider 507 Insert rod 611, a connecting block 603 is installed on the outer wall of one side of the direct guide rail 608 away from the limiting insert rod 611, and a T-shaped card plate 605 is inserted at the top and bottom of the gas chamber 602. The top of the T-shaped card plate 605 is provided with an air guide hole 614 that vertically penetrates the T-shaped card plate 605, and the T-shaped card plate 605 is provided with an arc-shaped air pipe 606 located above the air guide hole 614. The two ends of the T-shaped card plate 605 are rotatably connected with an oblique connecting rod 604 through a rotating shaft, and one end of the oblique connecting rod 604 away from the T-shaped card plate 605 is rotatably connected to the connecting block 603, and the bottom of the T-shaped card plate 605 is provided with a plug plate 615 located on the inner side of the gas chamber 602; The plug plate 615 is also provided with an air guide hole 614 located below the arc-shaped air pipe 606. By setting this structure, when the gap between the plug plates 615 is increased, the outside air enters between the two plug plates 615 through the arc-shaped air pipe 606 and the air guide hole 614. The diameter of the squeeze pin 609 is equal to the inner diameter of the direct guide rail 608, and the center of the squeeze pin 609 is misaligned with the center of the rotating disk 610. By setting this structure, the squeeze pin 609 drives the direct guide rail 608 to reciprocate in the horizontal direction when the rotating disk 610 rotates. In this embodiment, when the slider 507 moves with the connecting sleeve 512, the transmission coupling 612 moves synchronously with the slider 507. At this time, the spur gear 613 will rotate along the spur rack 601. When the spur gear 613 rotates, it drives the rotating disk 610 to rotate, so that the squeeze pin 609 drives the direct-connected guide rail 608 limited by the limiting plug rod 611 and the slider 507 to reciprocate in the horizontal direction. When the direct-connected guide rail 608 moves toward the air chamber 602, the connecting block 603 squeezes the oblique connecting rod 604, so that the T-shaped card When the plate 605 moves in a direction away from the air bin 602, the space between the two plug plates 615 inside the air bin 602 increases, so that the air inside the cabinet 1 enters the inner side of the air bin 602 through the arc-shaped air pipe 606 and the air guide hole 614. Similarly, when the direct-connected guide rail 608 moves in a direction away from the air bin 602, the plug plate 615 will squeeze the air between the plug plates 615 out of the air bin 602. The impact of the air ejected from the arc-shaped air pipe 606 on the air inside the cabinet 1 improves the fluidity of the air inside the cabinet 1, thereby further enhancing the heat dissipation effect of the equipment.

By setting this structure, the electromagnet 520 and the servo motor 502 are powered on and operated when the first contact piece 522 and the second contact piece 523 are in contact, thereby controlling the operating timing of the electromagnet 520 and the servo motor 502.

[0025] In this embodiment, when the cabinet door 2 is closed, the blocking rod 521 will be pressed. At this time, the blocking rod 521 will drive the first contact piece 522 to move toward the second contact piece 523, so that the first contact piece 522 is in contact with the second contact piece 523, and the third telescopic spring 524 is stretched, so that the electromagnet 520 and the servo motor 502 are powered on. Similarly, when the cabinet door 2 is opened, the blocking rod 521 loses its shielding and moves under the action of the elastic restoring force of the third telescopic spring 524, so that the second contact piece 523 is separated from the first contact piece 522, so that the electromagnet 520 and the servo motor 502 are powered off, so as to control the operation timing of the electromagnet 520 and the servo motor 502.
