Description
Technical Field
[0001] The present invention relates to the technical field of low-voltage switch cabinets, and in particular to an intelligent low-voltage switch cabinet that is easy to maintain. Background Art
[0002] Low-voltage switchgear is a device used to control, protect and distribute low-voltage power systems. Traditional low-voltage switchgear plays a vital role in the power distribution system, but its long-standing structural and functional defects have brought severe challenges to daily operation and maintenance and equipment reliability.
[0003] The main manifestations are systemic problems such as low heat dissipation efficiency, high maintenance costs, extremely inconvenient maintenance operations, and insufficient space utilization. First, in terms of heat dissipation, traditional designs mostly rely on heat dissipation holes opened in the cabinet for passive heat dissipation, or are supplemented by fixed fans for air circulation. However, such heat dissipation holes are very easy to absorb dust, fibers and other impurities in the environment and gradually accumulate and clog, seriously hindering airflow exchange, resulting in an exponential decrease in heat dissipation efficiency; at the same time, the fixed cooling fan has a single position and a rigid air supply path, which cannot achieve uniform heat dissipation in the cabinet. It is very easy to form stubborn local high-temperature hot spots in the area where the heating components are concentrated. Long-term high-temperature operation not only accelerates the aging of insulation materials and increases energy loss, but also directly shortens the life of sensitive electronic components. The service life of components and control equipment has become the root cause of equipment tripping and even fire hazards. Secondly, the traditional cabinet door structure design is too simple, and simple buckles or ordinary door locks are generally used for locking. The sealing performance is poor and there is a lack of effective locking mechanism. The switch operation lacks guidance and stability. After the cabinet door is closed, it cannot ensure a tight fit between the cabinet body. In dusty, humid or corrosive industrial environments, there is a serious risk of dust intrusion, water vapor penetration or corrosive gas penetration, which will deteriorate the insulation level and operational safety of the equipment in the cabinet over a long period of time. Thirdly, the installation structure of most switch cabinets is fixed, and the internal control components are installed densely, the layers are unclear, and the wiring is mixed. The inspection and maintenance of a single component often requires large-scale disassembly, and the maintenance operation is complicated and time-consuming. Summary of the Invention

[0028] The present invention will be further described below in conjunction with the accompanying drawings:
[0029] like Figures 1-10 As shown, this embodiment provides an intelligent low-voltage switch cabinet that is easy to maintain, including a switch cabinet body 1 and a fixing frame 2 placed on the ground. The bottom of the fixing frame 2 is fixedly installed on the top of the switch cabinet body 1. The switch cabinet body 1 is provided with heat dissipation holes 5 and mounting grooves 7 on one side and the front side, respectively. The air inside and outside the switch cabinet body 1 can be exchanged through the heat dissipation holes 5 and the cleanable rotating heat dissipation component 3, which has a better heat dissipation effect on the inside of the switch cabinet body 1. The cleanable rotating heat dissipation component 3 for cleaning the heat dissipation holes 5 is fixedly installed on the inner wall of the top of the fixing frame 2. The front side of the switch cabinet body 1 is fixedly installed with a sealing component 4. The sealing component 4 improves the sealing effect of the switch cabinet 1 and prevents external dust from entering the interior of the switch cabinet 1. A retractable mounting assembly 6 for mounting control elements is fixedly installed on the inner wall of the bottom of the switch cabinet 1. The retractable mounting assembly 6 not only allows the control elements to be installed in a classified manner, but also facilitates maintenance and repair of the control elements. A temperature sensor 8 for detecting the internal temperature of the switch cabinet 1 is installed on one side of the interior of the switch cabinet 1. The temperature sensor 8 can detect the temperature inside the switch cabinet 1. A control panel 9 is installed on the other side of the switch cabinet 1. The control panel 9 is electrically connected to the temperature sensor 8.
[0030] When the present invention is actually used, the appropriate temperature range of the switch cabinet 1 is set through the control panel 9. When the temperature sensor 8 detects that the internal temperature of the switch cabinet 1 exceeds the preset value, the control panel 9 starts the cleanable rotating heat dissipation component 3 to dissipate heat inside the switch cabinet 1. At the same time, it can also clean the dust attached to the heat dissipation holes 5 to prevent the heat dissipation holes 5 from being blocked. When it is necessary to maintain the internal control elements of the switch cabinet 1, the limit of the sealing component 4 is released. Then the operator can pull the retractable installation component 6 to facilitate the inspection or replacement of the control elements on the mounting plate 607. After the operation is completed, the retractable installation component 6 is pushed back to its original position and re-locked by the sealing component 4 to ensure the sealing and safety of the switch cabinet 1. In addition, the design of the retractable installation component 6 makes the installation and disassembly of internal control elements easier, greatly improving the maintenance efficiency. The entire intelligent low-voltage switch cabinet has a compact structure and comprehensive functions. It not only meets the control, protection and distribution requirements of the low-voltage power system, but also significantly improves the reliability and service life of the equipment.
[0031] As a technical optimization solution of the present invention, specifically Figure 5 As shown, the cleanable rotating heat dissipation component 3 includes an air duct 304 and a limiting frame 307. The air duct 304 is passed through and fixed on the top of the switch cabinet 1. One end of the air duct 304 is located inside the switch cabinet 1, and the other end of the air duct 304 is located above the switch cabinet 1, so as to facilitate the introduction of external air into the switch cabinet 1. A fan 306 is fixedly installed on the outside of the air duct 304. The limiting frame 307 is fixed on one side of the switch cabinet 1. A screw 308 with a threaded outer side is rotatably installed on the inner wall of the bottom of the limiting frame 307. A slider 309 is slidably installed on the outer side of the screw 308, and the slider 309 is threadedly connected to the screw 308. The limiting frame 307 has a limiting effect on the slider 309, so that the slider 309 can move up and down inside the limiting frame 307 instead of rotating. A cleaning brush 310 for cleaning the heat dissipation holes 5 is fixedly mounted on 309, a motor 301 is fixedly mounted on the top inner wall of the fixed frame 2, a first gear 303 is fixed to the outside of the output shaft of the motor 301, a second gear 305 is fixed to the outside of the air duct 304, the first gear 303 and the second gear 305 are meshed, the fan 306 is located above the second gear 305, the other end of the screw 308 passes through the top of the limiting frame 307 and is located above the limiting frame 307, synchronous wheels 302 are fixedly mounted on the outside of the screw 308 and the outside of the output shaft of the motor 301, synchronous belts 311 are meshed with the two synchronous wheels 302, and the synchronous belts 311 can drive the two synchronous wheels 302 to rotate simultaneously under the action of the synchronous belts 311.
[0032] When the present invention is in use, the motor 301 is started, and its output shaft drives the first gear 303 to rotate. The first gear 303 is meshed with the second gear 305, so that the second gear 305 drives the air duct 304 to rotate, and the air duct 304 can drive the fan 306 to rotate together. The fan 306 can introduce external air into the switch cabinet 1 through the air duct 304, and the motor 301 drives the air duct 304 to rotate through the gear set, which can continuously change the air outlet path, achieve more uniform and more efficient heat dissipation coverage, avoid local high temperature inside the cabinet, and improve the heat dissipation inside the switch cabinet 1. The effect is better. At the same time, the output shaft of the motor 301 can drive the screw 308 to rotate synchronously through the synchronous wheel 302 and the synchronous belt 311. The slider 309 connected to the outer side of the screw 308 by a thread makes a reciprocating linear motion along the axis direction of the screw 308 under the rotation of the screw 308. The slider 309 can drive the cleaning brush 310 to move together, so that the cleaning brush 310 can clean the dust attached to the outside of the heat dissipation hole 5 to prevent the heat dissipation hole 5 from being blocked, thereby ensuring the smooth flow of the heat dissipation channel, which not only improves the heat dissipation efficiency, but also realizes the automatic cleaning of the heat dissipation hole 5 and reduces the manual maintenance cost.
[0033] As a technical optimization solution of the present invention, specifically Figure 6-Figure 7 As shown, the sealing assembly 4 includes an L-shaped limit frame 401, and there are two L-shaped limit frames 401, which are fixedly installed on the front side of the switch cabinet body 1. The L-shaped limit frame 401 has a limiting effect on the switch cabinet door 402. A sliding groove 406 is provided on the inner side of the L-shaped limit frame 401, and a sliding block 407 is slidingly provided inside the sliding groove 406. The switch cabinet door 402 is fixed to the rear side of the two sliding blocks 407, and a handle 403 for driving the switch cabinet door 402 to move is fixed on the front side of the switch cabinet door 402. A square socket is provided on the switch cabinet door 402, and a spring 404 is fixedly installed inside the mounting groove 7. A limiting block 405 is fixed at the other end of the spring 404. The limiting block 405 is clamped inside the square socket and can lock the switch cabinet door 402, thereby improving the sealing and safety of the switch cabinet body 1.
[0034] When the present invention is in use, when the operator needs to open the switch cabinet door 402, he presses the limit block 405 into the installation groove 7. At this time, the spring 404 is in a compressed state. After the limit block 405 is separated from the switch cabinet door 402, the lock of the switch cabinet door 402 is released. The operator holds the handle 403 and pulls it outward. The handle 403 drives the switch cabinet door 402 to slide inside the slide groove 406 of the L-shaped limit frame 401 through the sliding block 407, and the switch cabinet door 402 can be opened, which is convenient for the staff to inspect the inside of the switch cabinet body 1. When the inspection is completed, when closing the switch cabinet door 402, the operator holds the handle 403 and pulls it in the opposite direction. The handle 403 drives the switch cabinet door 402 to slide inside the slide groove 406 of the L-shaped limit frame 401 through the sliding block 407 until the square socket moves to the front of the limit block 405. At this time, under the action of the spring 404, the limit block 405 is pushed to be stuck in the inside of the square socket, limiting the switch cabinet door 402, and the closing operation of the switch cabinet door 402 can be realized. The elastic action of the spring 404 is used to make the limit block 405 automatically stuck in the inside of the square socket, without manual locking, which improves the convenience of closing the switch cabinet door 402. The operation process is simple and fast, which is convenient for daily inspection and maintenance work.
[0035] As a technical optimization solution of the present invention, specifically Figures 8-10 As shown, the retractable mounting assembly 6 includes an inner frame 601 and a support plate 603. The bottom of the inner frame 601 is fixedly mounted on the bottom inner wall of the switch cabinet 1. Through holes 602 are provided on both sides of the inner frame 601 to improve the heat dissipation effect of the control components. One side of the support plate 603 is fixed to the inner side of the inner frame 601. A bottom plate 605 is provided on the top of the support plate 603. A mounting seat 606 is fixedly mounted on the top of the bottom plate 605. The mounting seat 606 can not only connect the bottom plate 605 and the mounting plate 607 together, but also drive the mounting plate 607 to rotate, which is convenient for maintenance of the control components installed on the top of the mounting plate 607. A mounting plate 607 is fixed, and the mounting plate 607 is located above the bottom plate 605. Fixed grooves 604 are provided on both sides of the inner frame 601, and a tooth plate 608 is fixed to the bottom of the fixing groove 604. A storage groove 609 is provided on the top of the bottom plate 605, and a rotating shaft 610 is installed inside the storage groove 609. Both ends of the rotating shaft 610 pass through the bottom plate 605 and third gears 611 are fixed to the outside of both ends of the rotating shaft 610. The third gear 611 is meshed with the tooth plate 608. Two top plates 612 are fixed to the outside of the rotating shaft 610, and the top plate 612 is located inside the storage groove 609. There are three groups of bottom plates 605, mounting seats 606 and mounting plates 607.
[0036] When the present invention is in use, the operator pulls the bottom plate 605, and the mounting seat 606 and the mounting plate 607 can move with the movement of the bottom plate 605, so that the control element installed on the top of the mounting plate 607 can be pulled out, which is convenient for the operator to repair or replace the control element. At the same time, the rotating shaft 610 drives the third gear 611 fixed on its outer side to engage and rotate on the tooth plate 608. Since the receiving groove 609 opened on the top of the bottom plate 605 has a limiting effect on the rotating shaft 610, the rotating shaft 610 can only rotate but not move axially. During the movement of the bottom plate 605, the top plate 612 will also rotate accordingly. Under the action of the top plate 612 and the mounting seat 606, the mounting plate 607 can be lifted up, so that the mounting plate 607 and the bottom plate 605 are connected. 05, which is convenient for the operator to inspect or replace the control components on the mounting plate 607. However, the top plate 612 is always located inside the storage slot 609 and will not interfere with the movement of the bottom plate 605. When the mounting plate 607 needs to be pushed back to its original position, the operator pushes the bottom plate 605 in the opposite direction, and the bottom plate 605 drives the mounting seat 606 and the mounting plate 607 to move together until the mounting plate 607 moves to the specified position inside the inner frame 601, and the rotating shaft 610 and the third gear 611 can rotate in the opposite direction, so that the top plate 612 is rotated back to the inside of the storage slot 609. The design of the retractable mounting assembly 6 not only realizes the classified installation and clear layout of the control components, but also greatly improves the maintenance efficiency and reduces the difficulty of operation.
[0037] In this embodiment, three groups of base plates 605, mounting seats 606 and mounting plates 607 are independently arranged. Each group of base plates 605 can be pulled out inside the inner frame 601, which is convenient for inspecting or replacing the control components on a certain group of mounting plates 607 separately, thereby improving the flexibility of maintenance.
