Abstract
Description
Technical Field
[0001] This invention relates to the field of power distribution cabinet technology, specifically a low-voltage integrated power distribution cabinet. Background Technology
[0002] A low-voltage integrated switchgear (commonly known as a JP cabinet) is an outdoor / indoor low-voltage complete set of power distribution equipment that integrates multiple functions such as power distribution, metering, protection, control, and reactive power compensation. It is mainly used for the terminal power distribution network on the low-voltage side (380V / 220V) of the distribution transformer. The cabinet is usually divided into multiple independent compartments to prevent mutual interference and facilitate maintenance. It is suitable for urban power grids, rural power grid renovation, industrial and mining enterprises, street lights, residential areas, etc. The low-voltage integrated switchgear mainly consists of a metering compartment and a switch compartment. Some also have a compensation compartment. If there is a compensation compartment, it is a three-compartment separation. If there is no compensation compartment, the compensator is installed inside the switch compartment.
[0003] However, currently, low-voltage integrated distribution cabinets installed at the bottom of outdoor transformers are generally mounted by welding flat iron to the top of the cabinet, which is then used to mount the cabinet onto a mounting frame at the bottom of the transformer. The transformer mounting frame is then installed between two utility poles. For safety reasons, these low-voltage integrated distribution cabinets are kept at a considerable distance from the ground. While this ensures pedestrian safety, the large distance and fixed position of the cabinet at the bottom of the transformer make height adjustment difficult. Maintenance requires auxiliary tools (ladders), and the high position makes operation inconvenient, reducing comfort and safety during maintenance. Furthermore, low-voltage distribution cabinets are typically manufactured before leaving the factory... Switches, input and output circuits, meters, and other equipment need to be installed inside. When installing these devices, the cabinet is placed on the ground. The cabinet's base cannot be supported, resulting in a low profile that requires workers to bend over to operate. The large number of electronic and electrical components makes installation inconvenient. Currently, low-voltage integrated distribution cabinets are generally divided into multiple chambers by partitions. These partitions are typically fixed to the cabinet and cannot be moved horizontally. The space in each chamber is fixed and cannot be adjusted. Operators cannot adjust the space of each chamber according to the number of electrical components inside the switch chamber, metering chamber, and compensation chamber, easily leading to wasted space or overcrowding, and affecting circuit safety. Summary of the Invention

[0007] Specifically, the engaging component is vertically installed at the center of the cabinet side wall, and the vertical rod and the flat iron form a T-shaped structure.
[0008] Specifically, the transmission assembly also includes a slide groove, with slide grooves provided on both sides of the two meshing parts, and the inner protrusion of the housing is embedded in the interior of the slide groove.
[0009] Specifically, the drive assembly also includes diagonal braces, and diagonal braces are fixedly connected at an angle between the two brackets and the two vertical rods.
[0010] Specifically, the outer shell and the cabinet are provided with a protective mechanism, which includes a connecting plate. Two connecting plates are fixedly connected to both sides of the two outer shells in a V-shape. The ends of the two sets of connecting plates are arranged opposite to the side wall of the cabinet.
[0011] Specifically, the protective mechanism also includes a limiting groove, rollers, and limiting plates. Rollers are rotatably connected to the ends of both sets of connecting plates. Two limiting grooves are symmetrically opened on both sides of the cabinet about the vertical rod. The rollers are rotatably connected inside the limiting grooves. A limiting plate that is slidably connected to the limiting groove is fixedly connected to the top of each connecting plate.
[0012] Specifically, the protective mechanism also includes a second connecting plate and ball bearings. The two limiting grooves on the same side are each provided with a second connecting plate that is fixedly connected to the cabinet. The second connecting plate is located at the highest point of the limiting groove. The ends of the two opposite second connecting plates are each provided with ball bearings, which are rolled and connected to the side wall of the vertical rod.
[0013] Specifically, the cabinet has an internal partition mechanism, which includes a partition. The cabinet has a partition inside, and guide plates are fixedly connected to the top and bottom of the cabinet. The sides of the guide plates are semi-circular. The guide plates are slidably connected to the partitions. Limiting holes are equidistantly opened on the guide plates at the bottom of the cabinet. An operating port is opened on the partition, and a lever is provided at the operating port. The bottom of the lever is fixedly connected to a positioning post that is slidably connected to the partition. The positioning post is inserted into the limiting hole. An elastic element two is clamped between the positioning post and the partition. The elastic element two is preferably a spring.
[0014] Specifically, the cabinet is equipped with a support mechanism, which includes four storage slots. The bottom of the cabinet has four rectangular storage slots, and each of the four storage slots has an inner rod slidably connected inside. Each of the four inner rods has a support rod rotatably connected to it, and each of the four support rods has a slot at its top. Each side of the cabinet is fixedly connected to two slide rails, and each of the two slide rails has a plug slidably connected inside. The plug is inserted into the slot, and an elastic element, which is a spring, is held between the slide rail and the plug.
[0015] The beneficial effects of this invention are: 1. The low-voltage integrated distribution cabinet of the present invention has an adjustment mechanism at the bottom of two flat irons. The flat irons are used to mount the adjustment mechanism and the cabinet on the mounting bracket at the bottom of the transformer. When the height of the cabinet needs to be adjusted, the servo motors on the two brackets are started. The output end of the servo motor drives the worm gear to rotate through the coupling. Since the worm gear and the gear mesh with each other, the rotation of the worm gear drives the gear to rotate synchronously. The gear and the rack mesh with each other. When the gear rotates, it drives the rack to move up and down in the vertical direction. The rack is fixedly installed on the side wall of the cabinet. Therefore, when the rack moves, it drives the cabinet to move up and down synchronously, realizing the adjustment of the cabinet height. This makes it convenient to lower the cabinet for maintenance when the internal circuit and electrical components of the cabinet at the bottom of the transformer are damaged. The two driving components control the synchronous lifting and lowering of the two racks.
[0016] 2. The low-voltage integrated distribution cabinet of this invention has an internal partitioning mechanism. This mechanism consists of two guide plates and partitions. When the internal space partitioning needs adjustment, the operator pulls a lever upwards through the operating port. The lever moves a positioning post upwards, disengaging it from the limiting hole. At this point, the elastic element is further stretched. Then, the partition is pushed, moving it left and right along the guide plates. After adjusting to the appropriate position, the lever is released. Under the tension of the spring, the positioning post moves downwards and inserts into the corresponding limiting hole, fixing the partition in its current position, thus completing the internal space partitioning adjustment. The equidistantly spaced limiting holes allow for multi-position adjustment of the partition position, adapting to the installation requirements of electrical components of different sizes. This facilitates adjusting the size of the metering chamber, compensation chamber, and switch chamber according to the size of the electrical components, offering convenient operation and high flexibility.
[0017] 3. The low-voltage integrated distribution cabinet of this invention has four support mechanisms installed at the bottom of the rectangular cabinet body. When installing electrical components and wiring inside the cabinet, firstly, pull the plug rod, the elastic element retracts, and the inner rod is pulled out from the storage slot. Then, rotate the support rod so that it rotates around the inner rod to a direction perpendicular to the ground. At this time, the slot at the top of the support rod aligns with the plug rod in the slide rail. Releasing the plug rod will cause it to automatically insert into the slot due to the elastic force of the elastic element, fixing the support rod in a vertical state. The bottom of the support rod contacts the ground, providing auxiliary support for the cabinet body, improving the placement stability and height of the cabinet, and facilitating the installation of electrical components and wiring by workers without bending over, thus improving work comfort. When the support is not needed, the support rod and inner rod can be retracted into the storage slot.
[0018] 4. The low-voltage integrated distribution cabinet of the present invention has a protective mechanism installed between the cabinet body and the outer shell. When the cabinet body is driven to rise and fall, the limiting groove can move along the first connecting plate, the roller can reduce the friction between the cabinet body and the first connecting plate, the limiting plate on the first connecting plate can prevent the cabinet body from slipping, the second connecting plate on the cabinet body can abut against the vertical rod, the ball can reduce the friction between the second connecting plate and the vertical rod, and both the first connecting plate and the second connecting plate can prevent the cabinet body from shaking and deviating when rising and falling.

Detailed Implementation
[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.
[0023] like Figures 1-10 As shown, the low-voltage integrated distribution cabinet of the present invention includes a cabinet body 1, a flat iron 2, a cabinet door 3, a conduit 4, an adjustment mechanism 5, a protective mechanism 6, a support mechanism 7, and a partitioning mechanism 8. These components work together to achieve lifting and adjustment, stable protection, support and fixation, and flexible internal space partitioning of the distribution cabinet, adapting to different installation scenarios and usage requirements. The specific settings, connection methods, and working processes of each component are described in detail below: In this invention, the cabinet 1 of the low-voltage integrated distribution cabinet is integrally formed from cold-rolled steel plate, with an overall rectangular structure, possessing good load-bearing and protective performance. The cabinet door 3 is connected to the front side of the cabinet 1 by hinges. The cabinet door 3 can be fitted with a door lock and observation window as needed, facilitating the operation and observation of the electrical components inside the cabinet 1. Two flat irons 2 are arranged parallel to each other on the top of the cabinet 1. Both flat irons 2 are galvanized flat irons and are installed on the vertical rod 501, not on the cabinet 1, only on the top two sides of the cabinet 1. Their length is adapted to the width of the cabinet 1 and is mainly used to fix and support the vertical rod 501 of the adjustment mechanism 5, ensuring the installation stability of the adjustment mechanism 5. Two conduits 4 are symmetrically arranged on one side of the cabinet 1, and can adopt a top-in, bottom-out wiring method. The incoming line from the transformer to the inside of the cabinet 1 should have an extra length to avoid damage to the cable when the cabinet 1 is lowered. The extra length is greater than the maximum descent distance of the cabinet 1, achieving a neat layout of the lines and avoiding safety hazards caused by messy lines.
[0024] A set of adjustment mechanisms 5 are symmetrically arranged on both sides of the cabinet 1. The adjustment mechanism 5 is the core component for the lifting and lowering adjustment of the cabinet 1. It consists of a transmission component and a drive component. The drive component provides power and controls the transmission component to drive the cabinet 1 to lift up and down, thereby flexibly adjusting the installation height of the cabinet 1, which facilitates the replacement and maintenance of electrical components and circuits inside the cabinet 1 at the bottom of the transformer at a high position. The transmission and drive components of the adjustment mechanism 5 work together to achieve smooth lifting and lowering of the cabinet 1. Its specific structure and working principle are as follows: Transmission components: The transmission assembly includes a vertical rod 501, a housing 502, an adjusting component 506, a power component 507, a meshing component 508, and a sliding groove 509. The bottoms of the two flat irons 2 are fixedly connected to the vertical rod 501 by welding. The vertical rod 501 is made of high-strength round steel, and its axis is perpendicular to the horizontal plane of the flat iron 2. The vertical rod 501 and the flat iron 2 form a T-shaped structure, which can effectively improve the support stability of the vertical rod 501 and prevent the vertical rod 501 from tilting under force. During installation, the flat iron 2 is fixed to the mounting bracket at the bottom of the transformer. The bottoms of the two vertical rods 501 are fixedly welded to the housing 502. The housing 502 adopts a sealed box structure with a sealing cover at the bottom for easy maintenance. The inside is used to install the adjusting component 506 and the power component 507, which plays a protective and dustproof role, preventing the internal components from being corroded by the external environment and extending their service life.
[0025] In this embodiment, the adjusting component 506 is preferably a worm gear, the power component 507 is preferably a gear, and the meshing component 508 is preferably a rack. The meshing of the three components enables power transmission. The power component 507 (gear) is rotatably connected to the interior of both outer shells 502 via bearings. Two meshing components 508 (racks) are fixedly installed on the opposing surfaces of both sides of the cabinet 1 via bolts. The racks are arranged vertically and located at the center of the side wall of the cabinet 1 to ensure that the racks are evenly stressed and drive the cabinet 1 to rise and fall smoothly. The two racks mesh with the two gears respectively. At the same time, the adjusting component 506 (worm gear) is rotatably connected to the interior of both outer shells 502 via bearings. The two worm gears mesh with the two gears respectively, forming a "worm-gear-rack" transmission structure. Utilizing the self-locking property of the worm gear transmission, the cabinet 1 can be effectively prevented from sliding down on its own after rising and falling, thus improving the safety and stability of the lifting adjustment.
[0026] To further improve the smoothness of the transmission process and prevent the rack from deviating when moving up and down, grooves 509 are provided on both sides of the two meshing parts 508 (racks). The grooves 509 extend vertically and their length matches the length of the rack. The inner side of the outer shell 502 is integrally formed with a protruding structure. The protruding structure is embedded in the groove 509 and is slidably connected with the groove 509. Through the cooperation between the groove 509 and the protrusion, the movement of the rack is guided and limited, ensuring that the rack always moves in the vertical direction, thereby ensuring that the cabinet 1 moves smoothly without deviation during the lifting process.
[0027] Driver components: The drive assembly includes a bracket 503, a drive component 504, and a diagonal brace 505, which provides power to the transmission assembly and controls the lifting and lowering of the cabinet 1. The brackets 503 are fixedly installed on the outer sides of the two outer shells 502 by bolts. The brackets 503 are made of angle steel and have good load-bearing capacity. The drive component 504 is installed on both brackets 503. In this invention, the drive component 504 is preferably a servo motor. The servo motor has the advantages of adjustable speed, high control accuracy, and stable operation. It can accurately control the lifting and lowering height of the cabinet 1. The output ends of the two servo motors are connected to the two adjusting components 506 (worm gears) through couplings. The couplings play a role in buffering and transmitting power, avoiding damage to the worm gear by the impact force generated when the servo motor starts, and ensuring that the power of the servo motor can be stably transmitted to the worm gear.
[0028] To improve the installation stability of the bracket 503 and prevent deformation of the bracket 503 under stress, diagonal braces 505 are fixedly connected to both brackets 503 and the two vertical rods 501 at an angle. The diagonal braces 505 are made of steel plates and are fixed to the brackets 503 and the vertical rods 501 at both ends by screws, forming a triangular support structure. The stability of the triangle is used to further strengthen the connection between the brackets 503 and the vertical rods 501, ensuring the stability of the drive component 504 during operation.
[0029] The working process of regulating mechanism 5: When the height of cabinet 1 needs to be adjusted, the servo motors on the two brackets 503 are started. The output end of the servo motor drives the worm (adjusting component 506) to rotate through the coupling. Since the worm and gear (power component 507) mesh with each other, the rotation of the worm drives the gear to rotate synchronously. The gear and rack (meshing component 508) mesh with each other. When the gear rotates, it drives the rack to move up and down in the vertical direction. The rack is fixedly installed on the side wall of cabinet 1. Therefore, when the rack moves, it drives cabinet 1 to move up and down synchronously, realizing the adjustment of the height of cabinet 1. This makes it convenient to lower cabinet 1 for maintenance when the internal circuit and electrical components of the bottom cabinet 1 of the transformer are damaged.
[0030] Because it is driven by a servo motor, the lifting height and direction of the cabinet 1 can be precisely controlled by controlling the speed and direction of rotation of the servo motor. At the same time, the meshing of the worm gear and gear has a self-locking function. When the servo motor stops running, the worm gear stops rotating, and the gear cannot rotate on its own, thus keeping the rack in a fixed position. The cabinet 1 is also fixed at the adjusted height and will not slide down on its own, ensuring safe use. During the lifting and lowering of the cabinet 1, the sliding grooves 509 on both sides of the rack and the protrusions on the inner side of the outer shell 502 cooperate with each other to guide the rack and prevent it from deviating, ensuring that the lifting and lowering of the cabinet 1 is smooth. Adjustment mechanisms 5 are provided on both sides of the cabinet 1 to make the lifting and lowering of the cabinet 1 more stable. The two servo motors move synchronously, so that their output speed, angle, and torque are consistent, eliminating the speed difference and position difference between the two sides. The two servo motors are controlled by a single controller to prevent the two racks from lifting and lowering asynchronously.
[0031] Specific implementation of protective mechanism 6 The outer casing 502 and the cabinet 1 are equipped with a protective mechanism 6, which is used to protect and limit the cabinet 1 during the lifting and lowering process, to prevent the cabinet 1 from tilting or shifting, and to improve the stability and safety of the equipment. The protective mechanism 6 includes a connecting plate 602, a limiting groove 601, a roller 605, a limiting plate 603, a connecting plate 604, and a ball bearing 606. Two connecting plates 602 are welded and fixed to both sides of the two outer casings 502 in a V-shape. The V-shape structure can improve the support strength of the connecting plates 602. The ends of the two sets of connecting plates 602 are set opposite to the side wall of the cabinet 1, and the ends of the two sets of connecting plates 602 are rotatably connected to the rollers 605 through bearings. The rollers 605 are made of wear-resistant rubber to reduce friction wear with the cabinet 1. Two limiting grooves are symmetrically opened on both sides of the cabinet 1 about the vertical rod 501. 601, the limiting groove 601 extends vertically, and its length is adapted to the height of the cabinet 1. The roller 605 is rotatably connected inside the limiting groove 601. When the cabinet 1 is raised and lowered, the roller 605 rolls synchronously inside the limiting groove 601. On the one hand, it plays a further guiding role in the raising and lowering of the cabinet 1. On the other hand, it can reduce the friction between the cabinet 1 and the connecting plate 602, reduce the resistance in the raising and lowering process, and make the raising and lowering of the cabinet 1 smoother. The top of the connecting plate 602 is welded and fixed with a limiting plate 603. The limiting plate 603 has an L-shaped structure, and its end is embedded in the limiting groove 601 and slidably connected with the limiting groove 601. The limiting plate 603 is used to limit the cabinet 1 to prevent the cabinet 1 from falling off. At the same time, it further improves the stability of the cabinet 1 in the raising and lowering process and prevents the cabinet 1 from deviating to the left or right.
[0032] Both limiting grooves 601 on the same side are equipped with connecting plates 604. The connecting plates 604 are fixedly connected to the outer wall of the cabinet 1 by bolts, and the connecting plates 604 are located at the highest point of the limiting grooves 601. The ends of the two opposite connecting plates 604 are embedded with balls 606. The balls 606 can rotate freely and are rolled in connection with the side wall of the vertical rod 501. When the cabinet 1 is raised or lowered, the balls 606 at the ends of the connecting plates 604 roll with the vertical rod 501, which limits the movement of the cabinet 1 and prevents the rack and gear from disengaging due to excessive rise of the cabinet 1. At the same time, the rolling of the balls 606 can reduce the friction between the connecting plates 604 and the vertical rod 501, avoid wear of parts, and increase the stability of the cabinet 1 when it is raised or lowered.
[0033] Specific implementation of support mechanism 7 The cabinet 1 is equipped with a support mechanism 7, which provides auxiliary support for the cabinet 1 when electrical components and wiring are installed inside, improving the stability and height of the cabinet 1 and enhancing the comfort of the operator. The support mechanism 7 includes four storage slots 707, an inner rod 702, a support rod 701, a slide rail 703, a plug rod 705, an elastic element 704, and a slot 706. The bottom of the cabinet 1 has four rectangular storage slots 707, located at the four corners of the bottom of the cabinet 1. The size of the storage slots 707 is adapted to the size of the inner rod 702 and the support rod 701, and is used to store the inner rod 702 and the support rod 701 to avoid occupying space when not in use. The inner rod 702 is slidably connected inside each of the four storage slots 707. The inner rod 702 can freely extend and retract along the length of the storage slot 707. Each inner rod 702 is rotatably connected to a support rod 701 via a hinge. The support rod 701 can rotate around the inner rod 702 to achieve unfolding and storage. Each of the four support rods 701 has a slot 706 at its top, which is horizontally oriented. Two slide rails 703 are welded and fixed to both sides of the cabinet 1. The slide rails 703 extend horizontally, and each slide rail 703 has a sliding rod 705 slidably connected inside. The size of the rod 705 is adapted to the size of the slot 706 and can be inserted into the slot 706 to fix the support rod 701. An elastic element 704 is held between the slide rail 703 and the rod 705. In this invention, the elastic element 704 is a spring. The spring is always in an open state and applies a spring force to the rod 705 in the direction of the slot 706 to ensure that the rod 705 will not detach itself after being inserted into the slot 706.
[0034] When installing electrical components and wiring inside cabinet 1, first pull the plug rod 705. The elastic element 704 retracts, pulling the inner rod 702 out of the storage slot 707. Then rotate the support rod 701 so that it rotates around the inner rod 702 to a direction perpendicular to the ground. At this time, the slot 706 at the top of the support rod 701 aligns with the plug rod 705 in the slide rail 703. Release the plug rod 705. Due to the elastic force of the spring (elastic element 704), the plug rod 705 will automatically insert into the slot 706, fixing the support rod 701 in a vertical state. The bottom of the support rod 701... The part contacts the ground, providing auxiliary support for the cabinet 1, improving the placement stability and height of the cabinet 1, making it easier for staff to install electrical components and wiring without bending over, thus improving work comfort. When the support is not needed, the plug rod 705 is manually pulled to disengage from the slot 706. At this time, the elastic element 704 is further compressed. Then, the support rod 701 is rotated to fold the support rod 701 parallel to the inner rod 702. The inner rod 702 is then pushed into the storage slot 707 to complete the storage of the support mechanism 7. The operation is convenient and does not take up extra space.
[0035] Specific implementation of the separation mechanism 8 The cabinet 1 has an internal partition mechanism 8 for flexibly dividing the internal space to accommodate the installation requirements of electrical components of different sizes. The partition mechanism 8 includes a partition 803, a guide plate 801, a limiting hole 802, an operating port 804, a lever 807, a positioning post 805, and an elastic element 806. The cabinet 1 has a partition 803 made of insulating material, which has good insulation properties to prevent short circuits between electrical components inside the cabinet 1. The top and bottom of the cabinet 1 are fixedly connected to the guide plate 801 by bolts. The guide plate 801 has a semi-circular side structure. The top and bottom of the partition 803 are embedded in the guide plate 801 and slidably connected to it. The partition 803 can move left and right along the guide plate 801, thereby adjusting its position inside the cabinet 1. The interior space is flexibly partitioned. Multiple limiting holes 802 are equidistantly spaced on the guide plate 801 at the bottom of the cabinet 1. The limiting holes 802 are circular and are used to cooperate with the positioning posts 805 to fix the partition 803. An operating port 804 is provided on the partition 803. The operating port 804 is rectangular, facilitating the operation of the lever 807. A lever 807 is located at the operating port 804, and a positioning post 805 is welded to the bottom of the lever 807. The size of the positioning post 805 matches the size of the limiting holes 802 and can be inserted into the limiting holes 802. An elastic element 806 is held between the positioning post 805 and the partition 803. In this invention, the elastic element 806 is preferably a spring. The spring is always in an open state, applying a downward pulling force to the positioning post 805 to ensure that the positioning post 805 will not detach itself after being inserted into the limiting hole 802.
[0036] When the internal space partition of cabinet 1 needs to be adjusted, the operator pulls the lever 807 upward through the operating port 804. The lever 807 drives the positioning post 805 upward, causing the positioning post 805 to disengage from the limiting hole 802. At this time, the spring (elastic element 806) is further stretched. Then, the partition 803 is pushed, causing the partition 803 to move left and right along the guide plate 801. After adjusting to the appropriate position, the lever 807 is released. Under the tension of the spring, the positioning post 805 moves downward and inserts into the corresponding limiting hole 802, fixing the partition 803 in the current position, thus completing the internal space partition adjustment of cabinet 1. Through the equidistantly set limiting holes 802, the position of the partition 803 can be adjusted in multiple positions to meet the installation requirements of electrical components of different sizes. It is convenient to adjust the size of the metering chamber, compensation chamber, and switch chamber according to the size of the electrical components, making the operation convenient and highly flexible.
[0037] In use, the invention begins by unfolding the support mechanism 7, pulling out the inner rod 702, and rotating the support rod 701 to insert the insertion rod 705 into the slot 706, bringing the four support rods 701 into contact with the ground to provide auxiliary support for the cabinet 1 and increase its height, facilitating the installation of electrical components and wiring inside the cabinet 1. Next, based on the dimensions of the electrical components, the position of the partition 803 is adjusted via the partition mechanism 8 to divide the internal space of the cabinet 1. During adjustment, the positioning post 805 is pulled to separate it from the limiting hole 802, and the partition 803 is moved horizontally. After determining the position, the positioning post 805 is released, the elastic element 806 resets, and the positioning post 805 inserts into the corresponding limiting hole 802, thus fixing the partition 803. Finally, the electrical components are installed inside the cabinet 1, the cabinet door 3 is closed, and the internal space is... The equipment is installed and debugged; the equipment is transported to the designated installation location, and the entire device is installed on the mounting frame at the bottom of the transformer using flat iron 2. The transformer's output wire is inserted into the conduit 4 above the cabinet 1 and connected to the electrical components inside the cabinet 1. The output wires from inside the cabinet 1 are discharged from the conduit 4 at the bottom. A portion of the cable length between the transformer and the cabinet 1 should be reserved, with the reserved length being greater than the descent distance of the cabinet 1 to avoid damage to the cable when the cabinet 1 descends. The height of the cabinet 1 is adjusted using the adjusting mechanism 5. The servo motor is started, driving the worm gear, gear, and rack transmission to raise and lower the cabinet 1 to the appropriate height. The servo motor stops running, and the height of the cabinet 1 is fixed by the self-locking property of the worm gear transmission. The two servo motors move synchronously, enabling the two gears to drive the two racks to move synchronously. The cabinet 1 descends for easy maintenance.
[0038] The following precautions should be taken during use: When adjusting the height of cabinet 1, ensure that the two servo motors run synchronously to prevent cabinet 1 from tilting; after the support mechanism 7 is unfolded, check whether the insertion rod 705 is fully inserted into the slot 706 to ensure stable support; when adjusting the partition mechanism 8, ensure that the positioning column 805 is fully inserted into the limit hole 802 to prevent the partition 803 from sliding; regularly check the meshing of the adjustment mechanism 5, the wear of the rollers 605 and balls 606 of the protective mechanism 6, the spring elasticity of the support mechanism 7, and the positioning of the partition mechanism 8, and perform timely maintenance and replacement to extend the service life of the equipment.
