Description

Technical Field

[0001] This invention relates to the field of switchgear technology, specifically to a pull-out power cabinet with line protection function. Background Technology

[0002] A pull-out power cabinet is an innovatively designed electrical equipment cabinet. It mainly consists of an outer cabinet shell and internal pull-out units. The outer cabinet shell is usually made of metal, such as cold-rolled steel plate, which serves to protect the internal equipment and provide electromagnetic shielding. The internal pull-out units are its core part. These units are similar to drawers and house various electrical equipment, such as circuit breakers, contactors, relays, fuses, etc., as well as the wiring connecting these devices.

[0003] Patent CN115102084B discloses a pull-out switchgear with line protection function. Addressing the problem that most existing pull-out switchgear lacks line protection and is difficult to position connecting wires, leading to easy detachment from the electrical switch, the patent proposes the following solution: A cabinet is included, with a mounting groove on one side. A drawer is slidably installed in the mounting groove. A pull plate is welded to one side of the drawer, and a handle is rotatably installed on one side of the pull plate. A connection port is provided on one side of the cabinet, containing a positioning mechanism. First sliding grooves are provided at the top and bottom of the pull plate, with locking blocks slidably installed in both grooves. This design provides line protection during use and facilitates the positioning of connecting wires, preventing detachment from the electrical switch. The structure is simple and easy to use.

[0004] However, the aforementioned devices are difficult to fully isolate and protect the internal wiring during use, which can lead to overheating of the wiring due to winding, affecting the normal operation of the equipment. Therefore, a pull-out power cabinet with wiring protection function is proposed to solve the above-mentioned problems. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to provide a pull-out power cabinet with line protection function, which addresses the shortcomings of the prior art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a pull-out power cabinet with line protection function, comprising a cabinet body, a rotating column rotatably connected to the inner wall of the cabinet body, a switch door fixedly connected to the circumference of the rotating column, a pull-out mechanism provided inside the cabinet body, ventilation mechanisms provided on the left and right sides of the cabinet body, a drying mechanism provided inside the cabinet body, a support block fixedly connected to the inner wall of the cabinet body, a dual-axis motor fixedly connected to the front of the support block, and the pull-out mechanism comprising a slide rail, rollers, a fixing block, and a column. The system comprises: Block 1, Connecting Rod, Cylindrical Block 2, Fixed Block 2, Pull-out Box, Connecting Plate, Elastic Telescopic Rod, Stabilizing Plate, Semi-circular Block 1, Semi-circular Block 2, and Pressure Plate.

The connecting rod is rotatably connected to the surface of Cylindrical Block 1. Cylindrical Block 2 is rotatably connected to the inner wall of the connecting rod. Fixed Block 2 is rotatably connected to the surface of Cylindrical Block 2. The pull-out box is fixedly connected to the... The top of the fixed block two, the connecting plate is fixedly connected to the rear of the pull-out box, the elastic telescopic rod is fixedly connected to the rear of the connecting plate, the stabilizing plate is fixedly connected to the telescopic end of the elastic telescopic rod, the first semi-circular block is fixedly connected to the rear of the pull-out box, the second semi-circular block is fixedly connected to the inner wall of the cabinet, the pressure plate is fixedly connected to the top of the second semi-circular block, the pull-out box is in contact with the roller, the second semi-circular block is in contact with the first semi-circular block, and the opening and closing door is in contact with the cabinet. This facilitates maintenance workers to perform maintenance and inspection of the internal wiring and to implement protective measures. It can improve the speed of wiring inspection and maintenance by workers, improve the stability of the wiring, and ensure that maintenance workers can quickly open the equipment and repair the internal equipment in the first instance of wiring damage. It can also stagger the wiring to avoid a large number of wires coming into contact and getting tangled, thus improving the safety of the equipment. If the wiring is not restrained and fixed, it will move and wear down its insulation layer. Once the insulation layer is damaged, the conductor will be exposed, increasing the possibility of leakage and short circuit. This can improve the service life of the equipment.

[0007] Preferably, the ventilation mechanism includes a rotating shaft, a dust cover, a connecting block, and fan blades. The rotating shaft is fixedly connected to the output end on the left side of the dual-axis motor. The dust cover is fixedly connected to the left side of the cabinet. The connecting block is fixedly connected to the circumferential surface of the rotating shaft, and the fan blades are fixedly connected to the circumferential surface of the connecting block. The ventilation mechanism also includes a pushing block, a connecting block, a striking rod, and a slanted scraper. The pushing block is fixedly connected to the inner wall of the pull-out drawer. The connecting block is fixedly connected to the left side of the cabinet. The striking rod is rotatably connected to the circumferential surface of the connecting block via a torsion spring. The slanted scraper is fixedly connected to the inner wall of the striking rod. The pushing block contacts the inner wall of the cabinet. The slanted scraper... The plate contacts the dust cover, and the rotating shaft is rotatably connected to the inner wall of the dust cover, allowing air circulation inside the equipment. This enables timely heat dissipation, preventing excessive heat from indirectly accelerating circuit aging. It also prevents the accumulation of harmful gases inside the power cabinet, avoiding corrosion of the metal components of electrical equipment. Good ventilation maintains the stability of circuit performance and reduces the negative impact of excessively high internal temperatures on circuit performance. This improves the ventilation effect of the dust cover, ensuring that external air can enter the equipment through the filter holes of the dust cover, reducing the internal temperature of the equipment, further improving the stability of the internal circuitry, and extending the service life of the equipment.

[0008] Preferably, the drying mechanism includes a rack block, a reciprocating screw, a gear, a second connecting block, a stirring plate, a drying box, and a limiting rod. The drying box is fixedly connected to the inner wall of the cabinet, the rack block is fixedly connected to the top of the pull-out box, the reciprocating screw is rotatably connected to the inner wall of the cabinet, the gear is fixedly connected to the circumferential surface of the reciprocating screw, the second connecting block is movably connected to the circumferential surface of the reciprocating screw, the stirring plate is fixedly connected to the circumferential surface of the second connecting block, the limiting rod is fixedly connected to the inner wall of the cabinet, and the stirring plate is slidably connected to the inner wall of the limiting rod. The drying mechanism also includes an L-shaped plate and a pressing cylinder. The L-shaped plate is fixedly connected to... The inner wall of the stirring plate is connected to the inner wall of the L-shaped plate by the rotatable cylinder, which contacts the drying box. The stirring plate contacts the surface of the drying box, and the gear meshes with the rack block to improve the effectiveness of the desiccant. This ensures that the equipment can be used in a humid environment while maintaining internal dryness, preventing short circuits caused by internal wiring, and ensuring the safety of the equipment. It can further move and crush some of the desiccant, improving the dryer's effectiveness and increasing the desiccant's adsorption efficiency. When crushed, it greatly increases the contact area with air, ensuring that the humidity inside the entire equipment can be controlled.

[0009] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0010] 1. This pull-out power cabinet with circuit protection function, through the coordinated movement of slide rails, rollers, fixing block one, cylindrical block one, connecting rod, cylindrical block two, fixing block two, pull-out box, connecting plate, elastic telescopic rod, stabilizing plate, semi-circular block one, semi-circular block two, and pressure plate, facilitates maintenance workers to perform maintenance and inspection of the internal circuitry and implement protective measures. It improves the speed of circuit inspection and maintenance, enhances circuit stability, and ensures that maintenance workers can quickly open the equipment to repair internal components in the event of circuit damage. It also allows for staggering of circuits, preventing excessive contact and entanglement, thus improving equipment safety. Without restraint, the circuits will move, causing wear on the insulation layer. Damage to the insulation layer exposes conductors, increasing the possibility of leakage and short circuits, thereby extending the equipment's service life.

[0011] 2. This pull-out power cabinet with circuit protection function, through the coordinated movement of the rotating shaft, dust cover, connecting block, fan blade, push block, connecting block, striking rod, and inclined scraper, allows air circulation inside the equipment.

It also reduces the negative impact of excessive internal temperature on circuit performance, improves the ventilation effect of the dust cover, and ensures that external air can enter the equipment through the filter holes of the dust cover, reducing the internal temperature and further improving the stability of the internal circuits, thus extending the service life of the equipment.

[0012] 3. This pull-out power cabinet with circuit protection function, through the coordinated movement of rack and pinion blocks, reciprocating screws, gears, connecting blocks, stirring plates, drying boxes, limit rods, L-shaped plates, and pressure cylinders, improves the effectiveness of the desiccant, ensuring that the equipment remains dry in humid environments. This prevents short circuits caused by internal wiring issues, ensuring the safety of the equipment. It can further move and crush some of the desiccant, improving the dryer's effectiveness and adsorption efficiency. Crushing the desiccant significantly increases the contact area with air, ensuring that the humidity inside the entire equipment is controlled. Attached Figure Description

[0023] 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.

[0024] Please see Figures 1-9One embodiment of the present invention is as follows: A pull-out power cabinet with line protection function includes a cabinet body 1, a rotating column 3 rotatably connected to the inner wall of the cabinet body 1, a switch door 2 fixedly connected to the circumference of the rotating column 3, a pull-out mechanism 4 provided inside the cabinet body 1, ventilation mechanisms 5 provided on the left and right sides of the cabinet body 1, a drying mechanism 6 provided inside the cabinet body 1, a support block 7 fixedly connected to the inner wall of the cabinet body 1, a dual-axis motor 8 fixedly connected to the front of the support block 7, and the pull-out mechanism 4 includes a slide rail 401, a roller 402, a first fixing block 403, a first cylindrical block 404, a connecting rod 405, a second cylindrical block 406, a second fixing block 407, a pull-out box 408, a connecting plate 409, an elastic telescopic rod 410, a stabilizing plate 411, a first semi-circular arc block 412, and a semi-circular arc block 413. Arc block 2 413, pressure plate 414, and slide rail 401 are fixedly connected to the inner wall of cabinet 1. Roller 402 is rotatably connected to the inner wall of slide rail 401. Fixed block 1 403 is fixedly connected to the inner wall of switch door 2. Cylindrical block 1 404 is rotatably connected to the inner wall of fixed block 1 403. Connecting rod 405 is rotatably connected to the surface of cylindrical block 1 404. Cylindrical block 2 406 is rotatably connected to the inner wall of connecting rod 405. Fixed block 2 407 is rotatably connected to the surface of cylindrical block 2 406. When the device is started, the switch door 2 is manually rotated and pulled open around the rotating column 3. At this time, the pulling force will drive the switch door 2 to rotate and open. The rotation and movement of the switch door 2 will drive the fixed block 1 403 to move. The movement of fixed block 1 403 will drive the cylindrical block 1 404 to move. The movement of cylindrical block 404 causes connecting rod 405 to move, which in turn causes cylindrical block 406 to move. The movement of cylindrical block 406 then causes fixed block 407 to move, which in turn causes pull-out box 408 to move outwards. Simultaneously, pull-out box 408 contacts roller 402, causing it to rotate and roll, making it easier to pull out. Multiple pull-out mechanisms 4 are provided, allowing multiple pull-out boxes 408 to be pulled out when the worker opens door 2. This facilitates maintenance workers in inspecting and protecting the internal wiring of the equipment, improving the speed of wiring inspection and maintenance. To improve the stability of the equipment's circuitry and ensure that maintenance workers can quickly open the equipment and repair the internal components in the event of a circuit failure, the following components are included: a pull-out box 408 is fixedly connected to the top of a second fixed block 407; a connecting plate 409 is fixedly connected to the rear of the pull-out box 408; an elastic telescopic rod 410 is fixedly connected to the rear of the connecting plate 409; a stabilizing plate 411 is fixedly connected to the telescopic end of the elastic telescopic rod 410; a first semi-circular block 412 is fixedly connected to the rear of the pull-out box 408; a second semi-circular block 413 is fixedly connected to the inner wall of the cabinet 1; a pressure plate 414 is fixedly connected to the top of the second semi-circular block 413; the pull-out box 408 contacts the roller 402; the second semi-circular block 413 contacts the first semi-circular block 412; and the opening / closing door 2 contacts the cabinet 1.Simultaneously, after the staff completes the circuit inspection, the switch door 2 is closed again. Switch door 2 will cause fixed block 403 to move, which in turn moves cylindrical block 404. The movement of cylindrical block 404 will then move connecting rod 405, which in turn will move cylindrical block 406. The movement of cylindrical block 406 will then move fixed block 407, which will in turn move pull-out box 408. Simultaneously, pull-out box 408 will move semi-circular block 412. After moving a certain distance, semi-circular block 412 will contact semi-circular block 413. At this point, the contact between semi-circular block 412 and semi-circular block 413 will form an approximate circle. During the movement of semi-circular block 412, semi-circular block 412... 2. The internal wiring of the device is pushed and controlled between semi-circular block 1 (412) and semi-circular block 2 (413), preventing it from moving. Before semi-circular block 1 (412) and semi-circular block 2 (413) make contact, the stabilizing plate (411) pushes and squeezes the wiring into contact with the pressure plate (414), preventing the wiring from moving before contact between the two blocks. Semi-circular blocks 1 (412) and semi-circular block 2 (413) have multiple semi-openings, allowing the wiring to be staggered during the movement of the wiring by semi-circular block 1 (412), avoiding excessive wiring contact and entanglement, thus improving the safety of the device. Without restraint, the wiring will move, causing wear on its insulation layer. Once the insulation layer is damaged, the conductor will be exposed, increasing the possibility of leakage and short circuits, thus extending the service life of the device.

[0025] The ventilation mechanism 5 includes a rotating shaft 501, a dust cover 502, a connecting block 504, and fan blades 505. The rotating shaft 501 is fixedly connected to the output end on the left side of the dual-axis motor 8. The dust cover 502 is fixedly connected to the left side of the cabinet 1. The connecting block 504 is fixedly connected to the circumferential surface of the rotating shaft 501, and the fan blades 505 are fixedly connected to the circumferential surface of the connecting block 504. When the dual-axis motor 8 is started, one output end of the dual-axis motor 8 drives the rotating shaft 501 to rotate. The rotation of the rotating shaft 501 drives the connecting block 504 to rotate. At this time, the connecting block 504 can draw external air into the equipment. The dust cover 502 on the outside of the cabinet 1 can prevent dust and other debris from entering. The air is drawn into the device by the rotation of the connecting block 504. Simultaneously, the output end of the right side of the dual-axis motor 8 drives the right-side rotating shaft 501 to rotate. The right-side rotating shaft 501 drives the right-side connecting block 504, which in turn drives the right-side fan blade 505 to rotate. At this time, the right-side fan blade 505 can expel the air from the device, allowing air circulation and timely heat dissipation. This prevents excessive heat from indirectly accelerating the aging of the wiring, prevents the accumulation of harmful gases inside the power cabinet, and avoids corrosion of the metal components of electrical equipment. Good ventilation can maintain the stability of the wiring performance and reduce the impact of excessively high internal temperatures on wiring performance. To mitigate negative impacts, the ventilation mechanism 5 also includes a push block 503, a connecting block 506, a striking rod 507, and a slanted scraper 508. The push block 503 is fixedly connected to the inner wall of the pull-out box 408, the connecting block 506 is fixedly connected to the left side of the cabinet 1, the striking rod 507 is rotatably connected to the circumferential surface of the connecting block 506 via a torsion spring, the slanted scraper 508 is fixedly connected to the inner wall of the striking rod 507, the push block 503 contacts the inner wall of the cabinet 1, the slanted scraper 508 contacts the dust cover 502, and the rotating shaft 501 is rotatably connected to the inner wall of the dust cover 502. Simultaneously, during the movement of the pull-out box 408, the movement of the pull-out box 408 will drive the push block 503 to move. During the movement of the push block 503, the push block 503 will... The striking rod 507 contacts and presses against the connecting block 506, causing it to rotate around the connecting block 506. During this rotation, the striking rod 507 contacts the surface of the dust cover 502 and strikes it. Simultaneously, the rotating striking rod 507 also moves the inclined scraper 508, which removes debris and dust from around the filter holes on the surface of the dust cover 502. This improves the ventilation of the dust cover 502, ensuring that external air can enter the equipment through the filter holes, reducing the internal temperature, further improving the stability of the internal circuitry, and extending the equipment's service life.

[0026] Working principle: When the device is started, the switch door 2 is manually rotated and pulled open around the rotating column 3. The pulling force causes the switch door 2 to rotate and open. The rotation of the switch door 2 causes the fixed block 403 to move, which in turn causes the cylindrical block 404 to move. The movement of the cylindrical block 404 causes the connecting rod 405 to move, which in turn causes the cylindrical block 406 to move. The movement of the cylindrical block 406 causes the fixed block 407 to move, which in turn causes the pull-out box 408 to move outwards. Simultaneously, the pull-out box 408 contacts the roller 402. During the movement of the pull-out box 408, it contacts the roller 402, causing the roller 402 to rotate and roll. The pull-out box 408 is easier to pull out, and multiple pull-out mechanisms 4 are provided. When the worker opens the switch door 2, multiple pull-out boxes 408 can be pulled out, facilitating maintenance workers to repair and inspect the internal wiring of the equipment and implement protective measures. This improves the speed of wiring inspection and repair, enhances the stability of the equipment's wiring, and ensures that maintenance workers can quickly open the equipment and repair the internal components in the event of wiring failure. After the worker completes the wiring inspection, closing the switch door 2 will move the fixed block 403, which in turn moves the cylindrical block 404. The movement of the cylindrical block 404 will then move the connecting rod 405. The movement of block 5 will also cause cylindrical block 2 406 to move, which in turn will cause fixed block 2 407 to move. Fixed block 2 407 will then cause pull-out box 408 to move. Simultaneously, pull-out box 408 will cause semi-circular block 1 412 to move. After semi-circular block 1 412 has moved a certain distance, it will contact semi-circular block 2 413. At this point, the contact between semi-circular block 1 412 and semi-circular block 2 413 will form an approximate circle. During the movement of semi-circular block 1 412, it will push the internal wiring of the device, controlling the wiring between semi-circular block 1 412 and semi-circular block 2 413, preventing it from... Before the semicircular block 1 412 and the semicircular block 2 413 come into contact, the stabilizing plate 411 will push and squeeze the line to contact the pressure plate 414 in advance, so that the line cannot move before the semicircular block 1 412 and the semicircular block 2 413 come into contact. The semicircular block 1 412 and the semicircular block 2 413 have multiple semi-openings, which can make the line staggered at a certain position during the process of the semicircular block 1 412 pushing the line to move, avoiding a large number of lines contacting and tangling, thus improving the safety of the equipment. If the line is not restrained and fixed, the line will move and wear its insulation layer. Once the insulation layer is damaged, the conductor will be exposed, increasing the possibility of leakage and short circuit, which can improve the service life of the equipment.

[0027] When the device is started, the dual-axis motor 8 will start. One output end of the dual-axis motor 8 will drive the rotating shaft 501 to rotate. The rotation of the rotating shaft 501 will drive the connecting block 504 to rotate. At this time, the connecting block 504 can draw external air into the device. The dust cover 502 on the outside of the cabinet 1 can prevent dust and other debris from entering the device through the rotation of the connecting block 504. At the same time, the output end of the right side of the dual-axis motor 8 will drive the right rotating shaft 501 to rotate. The right rotating shaft 501 will drive the right connecting block 504, which will drive the right fan blade 505 to rotate. At this time, the right fan blade 505 can expel the internal air of the device, so as to circulate the air inside the device, dissipate heat in time, avoid excessive heat that indirectly leads to accelerated aging of the circuit, prevent the accumulation of harmful gases inside the power cabinet, and prevent corrosion of the metal parts of electrical equipment. Good ventilation can maintain To maintain the stability of the circuit performance and reduce the negative impact of excessively high internal temperatures on the circuit performance, the sliding box 408 moves, which in turn moves the pushing block 503. During this movement, the pushing block 503 contacts and presses against the striking rod 507, causing the striking rod 507 to rotate around the connecting block 506. During this rotation, the striking rod 507 comes into contact with the surface of the dust cover 502. The tapping rod 507 is used to tap the dust cover 502. As the tapping rod 507 rotates, it also moves the inclined scraper 508. The inclined scraper 508 scrapes away debris and dust around the filter holes on the surface of the dust cover 502, improving the ventilation effect of the dust cover 502. This ensures that outside air can enter the equipment through the filter holes of the dust cover 502, reducing the internal temperature of the equipment, further improving the stability of the internal circuitry, and extending the service life of the equipment.

[0028] Please see Figures 1-9Based on the above embodiments, in another embodiment of the present invention, the drying mechanism 6 includes a rack block 601, a reciprocating screw 602, a gear 603, a connecting block 604, a stirring plate 605, a drying box 606, and a limiting rod 607. The drying box 606 is fixedly connected to the inner wall of the cabinet 1, the rack block 601 is fixedly connected to the top of the pull-out box 408, the reciprocating screw 602 is rotatably connected to the inner wall of the cabinet 1, the gear 603 is fixedly connected to the circumferential surface of the reciprocating screw 602, the connecting block 604 is movably connected to the circumferential surface of the reciprocating screw 602, the stirring plate 605 is fixedly connected to the circumferential surface of the connecting block 604, and the limiting rod 607. 7 is fixedly connected to the inner wall of cabinet 1. The stirring plate 605 is slidably connected to the inner wall of the limiting rod 607. When the device is started, the movement of the pull-out box 408 will drive its own rack block 601 to move. The movement of the rack block 601 will drive the gear 603 to move, causing the gear 603 to rotate. At this time, the rotation of the gear 603 will drive the reciprocating screw 602 to rotate. The reciprocating screw 602 will drive the stirring plate 605 to rotate. However, the stirring plate 605 is limited by the limiting rod 607. The limiting rod 607 makes the stirring plate 605 only able to move laterally reciprocating. The lateral reciprocating movement of the stirring plate 605 will drive the desiccant inside the drying box 606 to enter. During the movement of the stirring plate 605, the stirring plate 605 agitates the desiccant inside the drying box 606. This agitation increases the activity of the desiccant, improving its effectiveness and ensuring the equipment remains dry even in humid environments. This also prevents short circuits caused by internal wiring, ensuring the equipment's safety. The drying mechanism 6 also includes an L-shaped plate 608 and a pressing cylinder 609. The L-shaped plate 608 is fixedly connected to the inner wall of the stirring plate 605, and the pressing cylinder 609 is rotatably connected to the inner wall of the L-shaped plate 608. The pressing cylinder 609 contacts the drying box 606, and the stirring plate 605 and the drying box 606... The surface contact of the gear 603 and the rack block 601 is such that the gear 603 meshes with the rack block 601. At the same time, during the movement of the stirring plate 605, the lateral reciprocating movement of the stirring plate 605 will also drive the L-shaped plate 608 to move laterally. The movement of the L-shaped plate 608 will drive the pressure cylinder 609 to move laterally. During the movement, the pressure cylinder 609 comes into contact with the drying box 606, causing the pressure cylinder 609 to roll. This can further move some desiccant and crush some desiccant, which can improve the use effect of the dryer and improve the adsorption efficiency of the desiccant. After crushing, it will greatly increase the contact area with the air, ensuring that the humidity inside the entire equipment can be controlled.

[0029] Working principle: When the device is started, the movement of the pull-out box 408 will drive its rack block 601 to move. The movement of the rack block 601 will drive the gear 603 to move, causing the gear 603 to rotate. At this time, the rotation of the gear 603 will drive the reciprocating screw 602 to rotate, and the reciprocating screw 602 will drive the stirring plate 605 to rotate. However, the stirring plate 605 is limited by the limiting rod 607, which limits the stirring plate 605 to only move laterally. The lateral reciprocating movement of the stirring plate 605 will cause the desiccant inside the drying box 606 to move. During the movement, the stirring plate 605 will agitate the desiccant inside the drying box 606. The agitation of the desiccant will increase its activity and make it more effective. This method ensures better performance and guarantees that the equipment can be used in humid environments while maintaining internal dryness. It also prevents short circuits caused by internal wiring, ensuring the safety of the equipment. During the movement of the stirring plate 605, its lateral reciprocating movement also drives the L-shaped plate 608 to move laterally. The movement of the L-shaped plate 608 drives the pressure cylinder 609 to move laterally. During this movement, the pressure cylinder 609 comes into contact with the drying box 606, causing it to roll. This further agitates and crushes some of the desiccant, improving the dryer's effectiveness and increasing the desiccant's adsorption efficiency. Crushing the desiccant significantly increases the contact area with air, ensuring that the humidity inside the entire equipment is controlled.
