Description
Technical Field
[0001] The present invention relates to the technical field of control cabinets, and specifically to a weak-current intelligent control cabinet with a heat dissipation structure. Background Art
[0002] A control cabinet is a device that assembles switchgear, measuring instruments, protective electrical appliances, and auxiliary equipment in a closed or semi-closed metal cabinet or on a screen according to electrical wiring requirements. Its layout should meet the requirements for the normal operation of the power system, be convenient for maintenance, and not endanger the safety of personnel and surrounding equipment. When operating normally, it can connect or disconnect the circuit by means of manual or automatic switches. When a fault or abnormal operation occurs, the protective electrical appliance is used to cut off the circuit or give an alarm.
[0003] During the use of the control cabinet, the components inside it will generate heat due to long-term operation. At this time, heat dissipation treatment needs to be carried out inside the control cabinet. Generally, the heat dissipation of the control cabinet is achieved by installing a heat dissipation fan to discharge the heat inside the control cabinet to the outside of the cabinet. However, due to the large overall volume of the control cabinet and the different sizes of various electrical components, when the fan operates, the heat dissipation speed around the electrical components near the fan position will be relatively fast, while the air fluidity at the place far from the fan is poor due to the influence of the wind. This will lead to uneven heat dissipation inside the control cabinet, thus affecting the heat dissipation effect. Summary of the Invention

[0015] Compared with the prior art, the beneficial effects of the present invention are:
[0016] 1. By setting up a disconnection air guide component, when the servo motor is powered on and operating, the connecting sleeve block moves up and down reciprocally along the reciprocating lead screw. When the electromagnet is powered on, the magnetic attraction block moves in a direction away from the electromagnet. When the bolt aligns with the locking hole, the bolt will insert into the interior of the locking hole under the action of the elastic restoring force of the first telescopic spring. At this time, when the connecting sleeve block moves, it will drive the trapezoidal block to move synchronously through the bolt. In this way, the air suction pipe can extract the air at different positions inside the cabinet, so as 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, so that the trapezoidal block and the connecting sleeve block are disconnected, and after the cabinet door is opened, the slider and the air suction pipe are always at the inner bottom of the cabinet. In this way, it can prevent the slider and the air suction pipe from blocking the components inside the cabinet and affecting the maintenance operation of the staff on the cabinet;
[0017] 2. By setting up a flow-increasing jet component, when the slider moves synchronously with the connecting sleeve block, the transmission coupling shaft moves synchronously with the slider. At this time, the spur gear rotates along the straight rack. When the spur gear rotates, it drives the rotating disk to rotate, so as to make the squeezing connecting pin drive the straight connecting guide rail limited by the limiting plug rod and the slider to move reciprocally in the horizontal direction. When the straight connecting guide rail moves towards the air chamber, the connecting block squeezes the inclined connecting rod, so as to make the T-shaped clamping plate move in a direction away from the air chamber. At this time, the space between the two plug plates inside the air chamber increases, so that the air inside the cabinet enters the inner side of the air chamber through the arc-shaped air pipe and the air guide hole. Similarly, when the straight connecting guide rail moves away from the air chamber, the plug plate will squeeze out the air located between the plug plates from the air chamber, and the impact of the air ejected through 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;
[0018] 3. By setting up a touch position control unit, when the cabinet door is closed, it presses the blocking rod. At this time, the blocking rod drives the first contact piece to move towards the second contact piece, so that the first contact piece contacts the second contact piece, and at the same time the third telescopic spring extends, so that the electromagnet and the servo motor are powered on and operating. Similarly, when the cabinet door is opened, the blocking rod moves under the action of the elastic restoring force of the third telescopic spring because it loses the block, so that the second contact piece is separated from the first contact piece, so that the electromagnet and the servo motor are powered off, so as to control the operation timing of the electromagnet and the servo motor.

The following describes the embodiments according to the overall structure of the present invention.
[0031] Embodiment 1. Please refer to Figures 1 to 9 , in the embodiment of the present invention, a weak-current intelligent control cabinet with a heat dissipation structure includes a cabinet body 1. A protective baffle 3 is installed on the top of the cabinet body 1. A heat dissipation fan 4 is arranged on the top of the cabinet body 1 below the protective baffle 3. One end of the cabinet body 1 is rotatably connected to a cabinet door 2 through a hinge. A side connection bin 501 is installed on one side of the cabinet body 1. An air-breaking guiding member extending into the interior of the cabinet body 1 is arranged inside the side connection bin 501. An air suction pipe 508 is connected to the interior of the cabinet body 1 through the air-breaking guiding member. A gap is formed on one side of the air suction pipe 508. Gas enters the interior of the air suction pipe 508 through the air suction pipe 508. An air chamber 602 is installed on the side of the air suction pipe 508 close to the cabinet door 2. An air flow increasing and jetting member is arranged on the air chamber 602. A touch position control unit connected to the air-breaking guiding member is arranged at the bottom of the cabinet body 1.
[0032] In this embodiment, when the heat dissipation fan 4 is started and the cabinet door 2 is closed, the touch position control unit controls the air-breaking guiding member to operate as the cabinet door 2 is closed, so as to enable the air suction pipe 508 to extract the air at different positions inside the cabinet body 1, and then discharge it from the cabinet body 1 through the operation of the heat dissipation fan 4. During this process, the air flow increasing and jetting member operates synchronously with the air-breaking guiding member, and the operation of the air flow increasing and jetting member increases the fluidity of the air inside the cabinet body 1, further improving the heat dissipation efficiency of the cabinet body 1.
[0033] Embodiment 2. Please pay special attention to Figure 1 , Figure 2 , Figure 3 , Figure 6 , Figure 7 , Figure 8, the disconnection air guiding part includes a servo motor 502 installed at the bottom of the side connection bin 501. The output end of the servo motor 502 is connected to a reciprocating lead screw 511 located inside the side connection bin 501. A connecting sleeve block 512 is movably sleeved on the reciprocating lead screw 511. One side of the connecting sleeve block 512 close to the cabinet body 1 is provided with a sleeve 513. An electromagnet 520 is installed on the inner wall of the sleeve 513. A push rod 517 passing through to the outside of the sleeve 513 is inserted into the sleeve 513. One end of the push rod 517 is provided with a magnetic attraction block 519 located inside the sleeve 513. One end of the magnetic attraction block 519 away from the electromagnet 520 is provided with a second telescopic spring 518 connected to the inner wall of the sleeve 513. The second telescopic spring 518 is located outside the push rod 517. One end of the push rod 517 away from the magnetic attraction block 519 is provided with a push position plate 514. The two ends of the push position plate 514 are inserted with pins 515. One side of the push position plate 514 close to the sleeve 513 is provided with a first telescopic spring 516 connected to the pin 515. The inner wall of the cabinet body 1 is provided with a positioning guide rod 505 flush with the side connection bin 501. A slider 507 is movably sleeved on the positioning guide rod 505. An air suction pipe 508 is installed on one side of the slider 507. The bottom of the heat dissipation fan 4 is provided with an air guiding hose 504 connected to the air suction pipe 508. One side of the slider 507 close to the side connection bin 501 is provided with a trapezoidal block 506. A locking hole 509 is opened on one side of the trapezoidal block 506 away from the slider 507. A counterweight block 510 is provided at the bottom of the slider 507;
[0034] Both sides of the connecting sleeve block 512 are in contact with the inner wall of the side connection bin 501. A crescent pin matching the outside of the reciprocating lead screw 511 is arranged inside the connecting sleeve block 512. By setting this structure, when the reciprocating lead screw 511 rotates, the connecting sleeve block 512 moves up and down reciprocally along the reciprocating lead screw 511;
[0035] One end of the pin 515 away from the sleeve 513 is rotatably connected with a ball through a rotating shaft. The diameter of the locking hole 509 is equal to that of the pin 515. By setting this structure, the friction between the pin 515 and the trapezoidal block 506 is reduced, and at the same time, the stability of the connection between the trapezoidal block 506 and the connecting sleeve block 512 when the pin 515 is inserted into the locking hole 509 is improved;
[0036] The number of the positioning guide rods 505 is set to four. The four positioning guide rods 505 are evenly divided into two groups. The two groups of positioning guide rods 505 are symmetrically arranged along the vertical central axis of the cabinet body 1. By setting this structure, the stability of the vertical movement of the slider 507 and the air suction pipe 508 is improved;
[0037] In this embodiment, when the cabinet door 2 is closed, the servo motor 502 and the electromagnet 520 are energized and operated through the contact position control unit. When the servo motor 502 is energized and operated, it drives the reciprocating lead screw 511 to rotate. When the reciprocating lead screw 511 rotates, the connecting sleeve block 512 moves up and down reciprocally along the reciprocating lead screw 511. When the electromagnet 520 is energized, the magnetic attraction block 519 moves in a direction away from the electromagnet 520 under the repulsive force of the electromagnet 520, and at the same time, the second telescopic spring 518 contracts, so that the end of the bolt 515 away from the sleeve 513 moves to a position flush with the side of the trapezoidal block 506 close to the slider 507. As the connecting sleeve block 512 moves, the bolt 515 contacts the trapezoidal block 506. At this time, through the inclined plane guiding of the trapezoidal block 506, the bolt 515 moves relative to the pushing plate 514, so that the bolt 515 moves towards the sleeve 513, and at the same time, the first telescopic spring 516 extends. When the bolt 515 is aligned with the locking hole 509, the bolt 515 is inserted into the locking hole 509 under the action of the elastic restoring force of the first telescopic spring 516. At this time, when the connecting sleeve block 512 moves, it drives the trapezoidal block 506 to move synchronously through the bolt 515, so as to change the position of the suction pipe 508. In this way, the suction pipe 508 can extract the air at different positions in the cabinet body 1, so as to ensure the uniformity of heat dissipation inside the cabinet body 1. When the cabinet door 2 is opened, the electromagnet 520 and the servo motor 502 are powered off under the action of the contact position control unit. At this time, the magnetic attraction block 519 fits with the electromagnet 520 under the action of the elastic restoring force of the second telescopic spring 518, so that the pushing plate 514 drives the bolt 515 to move towards the sleeve 513, so as to pull out the bolt 515 from the locking hole 509, so that the trapezoidal block 506 loses connection with the connecting sleeve block 512. At this time, the slider 507 will fall under the action of the counterweight 510, so that the slider 507 and the suction pipe 508 are always at the inner bottom of the cabinet body 1 after the cabinet door 2 is opened. In this way, it can 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 staff on the cabinet body 1.
[0038] Embodiment 3, please refer with emphasis to Figure 2 、 Figure 3 、 Figure 4 、 Figure 5, the flow-increasing jet component includes a mounting base 607 installed on one side of the slider 507. One end of the mounting base 607 away from the suction pipe 508 is rotatably connected to a transmission coupling shaft 612 through a bearing. One end of the transmission coupling shaft 612 is installed with a rotating disk 610. A spur gear 613 is arranged on the transmission coupling shaft 612 between the mounting base 607 and the rotating disk 610. A spur rack 601 meshing with the spur gear 613 is installed on the inner wall of the cabinet body 1. One end of the rotating disk 610 is installed with a displacement extrusion pin 609. A straight connection guide rail 608 is sleeved on the displacement extrusion pin 609. A limit insertion rod 611 slidably connected to the slider 507 is arranged on the outer wall of the straight connection guide rail 608. A connection block 603 is installed on the outer wall of the straight connection guide rail 608 away from the limit insertion rod 611. T-shaped clamping plates 605 are inserted at the top and bottom of the air chamber 602. A vent hole 614 vertically penetrating the T-shaped clamping plate 605 is opened at the top of the T-shaped clamping plate 605. An arc-shaped air pipe 606 is arranged on the T-shaped clamping plate 605 above the vent hole 614. The two ends of the T-shaped clamping plate 605 are rotatably connected to an inclined connection rotating rod 604 through a rotating shaft. One end of the inclined connection rotating rod 604 away from the T-shaped clamping plate 605 is rotatably connected to the connection block 603. A plug plate 615 is arranged at the bottom of the T-shaped clamping plate 605 inside the air chamber 602;
[0039] The plug plate 615 is also provided with a vent hole 614 below the arc-shaped air pipe 606. By setting this structure, when the gap between the plug plates 615 increases, outside air enters between the two plug plates 615 through the arc-shaped air pipe 606 and the vent hole 614;
[0040] The diameter of the displacement extrusion pin 609 is equal to the inner diameter of the straight connection guide rail 608. The center of the displacement extrusion pin 609 and the center of the rotating disk 610 are in a misaligned state. By setting this structure, when the displacement extrusion pin 609 rotates with the rotating disk 610, the displacement extrusion pin 609 drives the straight connection guide rail 608 to perform a reciprocating movement in the horizontal direction;
[0041] In this embodiment, when the slider 507 moves along with the connecting sleeve block 512, the transmission coupling shaft 612 moves synchronously with the slider 507. At this time, the spur gear 613 rotates along the straight rack 601. When the spur gear 613 rotates, it drives the rotating disk 610 to rotate, so that the squeezing connecting pin 609 drives the straight connecting guide rail 608 limited by the limit plug rod 611 and the slider 507 to move reciprocally in the horizontal direction. When the straight connecting guide rail 608 moves towards the air chamber 602, the connecting block 603 squeezes the inclined connecting rod 604, so that the T-shaped clamping plate 605 moves away from the air chamber 602. At this time, the space between the two plug plates 615 inside the air chamber 602 increases, so that the air inside the cabinet 1 enters the inner side of the air chamber 602 through the arc-shaped air pipe 606 and the air guide hole 614. Similarly, when the straight connecting guide rail 608 moves away from the air chamber 602, the plug plate 615 squeezes the air between the plug plates 615 out of the air chamber 602, and the impact of the air ejected through the arc-shaped air pipe 606 on the air inside the cabinet 1 improves the fluidity of the air inside the cabinet 1, further enhancing the heat dissipation effect of the device.
[0042] Embodiment 4, please refer specifically to Figure 1 、 Figure 6 、 Figure 8 、 Figure 9 。 The touch position control unit includes a connecting cylinder 503 installed at the bottom of the cabinet 1. The inner wall of the connecting cylinder 503 is provided with a second contact piece 523. A blocking rod 521 extending to the outside of the connecting cylinder 503 is inserted into the connecting cylinder 503. One end of the blocking rod 521 is provided with a first contact piece 522 located inside the connecting cylinder 503. A third telescopic spring 524 connected to the connecting cylinder 503 is arranged on the side of the first contact piece 522 away from the second contact piece 523. The third telescopic spring 524 is located outside the blocking rod 521;
[0043] The first contact piece 522 is electrically connected to an external power supply through a wire, and the second contact piece 523 is electrically connected to the electromagnet 520 and the servo motor 502 through a wire. By setting this structure, when the first contact piece 522 contacts the second contact piece 523, the electromagnet 520 and the servo motor 502 are powered on and operate, so as to control the operation timing of the electromagnet 520 and the servo motor 502.
[0044] In this embodiment, when the cabinet door 2 is closed, the blocking rod 521 is pressed. At this time, the blocking rod 521 drives the first contact piece 522 to move towards the second contact piece 523, so that the first contact piece 522 contacts the second contact piece 523. At the same time, the third telescopic spring 524 extends, so that the electromagnet 520 and the servo motor 502 are energized and operate. Similarly, when the cabinet door 2 is opened, the blocking rod 521 moves under the action of the elastic restoring force of the third telescopic spring 524 due to the loss of occlusion, 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.
[0045] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, equivalent substitution or change should be covered within the protection scope of the present invention.
