Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and more specifically, to a modular intelligent easy-to-disassemble power distribution cabinet. Background Technology

[0002] A power distribution cabinet is an electrical equipment assembly used for centralized control and distribution of electrical energy, as well as protection, monitoring, and control of circuits and electrical equipment. It contains components such as switches, fuses, relays, and measuring instruments, which work together to achieve the rational distribution and management of electrical energy. In centralized power supply environments such as industry and buildings, it acts as a power center and main power distribution device. It monitors the power system in real time through instruments such as ammeters and voltmeters, and supports fault recording and remote digital management.

[0003] Traditional power distribution cabinet structures typically use welding or bolts to fix mounting plates or beams to the cabinet side walls. This means that once the height of the mounting plate is determined, it cannot be adjusted. When installing electrical components such as circuit breakers, contactors, and PLC modules of varying sizes and types, the fixed position of the mounting plate severely limits the flexibility of equipment layout. It is difficult to allocate space reasonably according to the actual size of the components, and it is also impossible to optimize the wiring path as needed. This often results in either underutilization of cabinet space, leading to waste, or a crowded and messy appearance due to excessive component density. This not only greatly increases the construction difficulty and time cost in the early installation and wiring stages, but also forces operators to carry out large-scale disassembly, re-drilling, and reinstallation work when the system needs to be expanded or equipment replaced later. The entire process is time-consuming and labor-intensive, significantly increasing the complexity and economic cost of maintenance. At the same time, it also increases the risk of system failure due to misoperation during frequent modifications.

[0004] In summary, in order to simplify the installation and maintenance process and improve work efficiency, it is necessary to solve the problem that the traditional power distribution cabinet has a fixed structure that cannot be adjusted, which seriously limits the flexibility of equipment layout and increases the complexity and economic cost of maintenance. The goal is to enable the power distribution cabinet to be flexibly adjustable to adapt to electrical components of different sizes and types. Utility Model Content

[0005] The present invention provides a modular intelligent easy-to-disassemble electrical cabinet, which aims to solve the problem that traditional electrical cabinets have a fixed structure and cannot be adjusted, which seriously limits the flexibility of equipment layout and increases the complexity and economic cost of maintenance.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular intelligent easy-to-disassemble electrical cabinet, including a cabinet body, several cabinet doors rotatably connected to the cabinet body, two symmetrical uprights fixedly connected inside the cabinet body, racks fixedly connected to the uprights, a limiting sleeve sleeve fitted on the outside of the uprights, the limiting sleeve fixedly connected to the cabinet body, multiple mounting brackets arranged from top to bottom inside the cabinet body, two adjusting components symmetrically installed on both sides of the mounting brackets, the adjusting components being connected to the racks, the adjusting components being used to manually drive the mounting brackets to perform linear movement, the mounting brackets having sliding grooves, and guide rails fixedly connected inside the cabinet body, the guide rails and sliding grooves being slidably connected.

[0007] In a preferred embodiment, the adjustment assembly includes a rotating shaft rotatably connected to a mounting bracket at one end, a knob fixedly connected to the other end of the rotating shaft, and a gear fixedly connected to the rotating shaft. The gear and rack are meshed together, and the rotating shaft and the limiting sleeve are slidably connected.

[0008] In a preferred embodiment, an air inlet is provided at the bottom of the cabinet, and a cooling component is installed on the air inlet to generate airflow to blow into the cabinet.

[0009] In a preferred embodiment, the cooling component includes a ventilation duct fixedly connected to the air inlet, a stepper motor fixedly connected inside the ventilation duct, and fan blades fixedly connected to the output end of the stepper motor. The stepper motor is used to drive the fan blades to rotate.

[0010] In a preferred embodiment, two temperature sensors are symmetrically fixedly connected to both sides of the mounting bracket. The temperature sensors are used to detect temperature changes inside the cabinet in real time and transmit signals to the control system on the cabinet.

[0011] In a preferred embodiment, two sliders are symmetrically fixedly connected to both sides of the mounting bracket, and two symmetrical guide rods are fixedly connected inside the cabinet, with the guide rods and sliders being slidably connected.

[0012] In a preferred embodiment, an air outlet is provided on the top of the cabinet, and a top cover is fixedly connected to the air outlet.

[0013] The beneficial effects of this utility model are as follows: This invention utilizes the meshing transmission of gears and racks to drive the mounting bracket to achieve smooth and stepless vertical lifting without the need for any tools. This breaks the rigid constraints of traditional distribution cabinet layouts, allowing the cabinet space to be freely and flexibly allocated according to the actual size of components and wiring requirements, thereby maximizing space utilization. When installing equipment, maintaining lines, or replacing components, operators can easily lower the mounting bracket to the most suitable operating height, significantly reducing the technical difficulty and labor intensity of installation and maintenance, and significantly shortening the downtime required for maintenance, thus achieving the goal of easy disassembly and assembly.

[0020] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0021] Refer to the instruction manual appendix Figures 1 to 5 A modular intelligent easy-to-disassemble electrical cabinet includes a cabinet body 1, several cabinet doors 2 rotatably connected to the cabinet body 1, two symmetrical uprights 4 fixedly connected inside the cabinet body 1, racks 5 fixedly connected to the uprights 4, a limiting sleeve 6 sleeved on the outside of the uprights 4, the limiting sleeve 6 fixedly connected inside the cabinet body 1, multiple mounting brackets 7 arranged from top to bottom inside the cabinet body 1, two adjusting components symmetrically installed on both sides of the mounting brackets 7, the adjusting components are connected to the racks 5, the adjusting components are used to manually drive the mounting brackets 7 to perform linear movement, the mounting brackets 7 are provided with sliding grooves 701, a guide rail 14 fixedly connected inside the cabinet body 1, the guide rail 14 and the sliding grooves 701 are slidably connected.

[0022] It should be noted that the cabinet 1 contains a PLC control system, which can provide real-time feedback on the situation inside the cabinet to the user. The cabinet door 2 is connected to the cabinet 1 by hinges and is equipped with a door lock and observation window for easy observation of the inside of the cabinet. The mounting bracket 7 has mounting holes with standard hole spacing for mounting trays of electrical components such as circuit breakers, contactors, PLCs, and terminal blocks.

[0023] It is worth noting that two symmetrical uprights 4 are fixed on both sides inside the cabinet 1, and the rack 5 is fixedly installed on the side of the uprights 4 facing the mounting bracket 7. This is used to realize the vertical movement and leveling of the mounting bracket 7 and position locking. Each tooth on the rack 5 is equivalent to a precise positioning point, and the limiting sleeve 6 is fixed between the top plate and the bottom plate of the cabinet 1, through which the uprights 4 pass. This limits the bending or vibration that may occur when the uprights 4 bear the weight of the mounting bracket 7 and components, ensuring that the rack 5 and the adjustment assembly always maintain a stable connection, thereby improving the reliability and durability of the system.

[0024] Refer to the instruction manual appendix Figure 5 The adjustment assembly includes a rotating shaft 8 with one end rotatably connected to the mounting bracket 7, a knob 10 fixedly connected to the other end of the rotating shaft 8, and a gear 9 fixedly connected to the rotating shaft 8. The gear 9 is meshed with the rack 5, and the rotating shaft 8 is slidably connected to the limiting sleeve 6.

[0025] It should be noted that the gear 9 and rack 5 are size-matched to achieve stable power transmission. By manually turning the knob 10, the rotational motion of the gear 9 is converted into linear motion on the rack 5.

[0026] It is worth noting that both gear 9 and rack 5 are helical teeth, which not only makes the transmission smoother and the noise lower, but also has a certain self-locking effect. When the rotation stops, the friction between gear 9 and rack 5 can effectively prevent the mounting bracket 7 from sliding down due to its own weight, thus playing a locking role.

[0027] Refer to the instruction manual appendix Figure 2 The bottom of the cabinet 1 has an air inlet 101, and a cooling component is installed on the air inlet 101. The cooling component is used to generate airflow to blow into the cabinet 1.

[0028] It should be noted that the air inlet 101 is located at the bottom of the cabinet 1, connecting the outside air, the cooling components and the cabinet 1. It follows the chimney effect principle of hot air rising, forming an efficient and natural airflow circulation path.

[0029] Refer to the instruction manual appendix Figure 4 The cooling component includes a ventilation pipe 301 fixedly connected to the air inlet 101, a stepper motor 302 fixedly connected inside the ventilation pipe 301, and a fan blade 303 fixedly connected to the output end of the stepper motor 302. The stepper motor 302 is used to drive the fan blade 303 to rotate.

[0030] It should be noted that the stepper motor 302 is installed inside the ventilation pipe 301, which drives the fan blade 303 to rotate, generating airflow that blows into the cabinet 1 to achieve the cooling process.

[0031] Refer to the instruction manual appendix Figure 5Two temperature sensors 11 are symmetrically fixedly connected to both sides of the mounting bracket 7. The temperature sensors 11 are used to detect the temperature change inside the cabinet 1 in real time and transmit the signal to the control system on the cabinet 1.

[0032] It should be noted that the temperature sensor 11 converts the physical temperature signal into an electrical signal and transmits it to the control system inside the cabinet 1 to determine the temperature level, thereby controlling the rotation speed of the fan blade 303 and controlling the airflow. If the temperature exceeds the normal range, an alarm will be issued. The model of the temperature sensor 11 in this device is CWDZ11.

[0033] Refer to the instruction manual appendix Figure 3 The mounting bracket 7 has two sliders 12 fixedly connected symmetrically on both sides, and two guide rods 13 fixedly connected inside the cabinet 1. The guide rods 13 and sliders 12 are slidably connected.

[0034] It should be noted that the slider 12 has a through hole, the size of which is adapted to the guide rod 13, so that the slider 12 can slide on the guide rod 13, thereby achieving movement limit on both sides of the mounting bracket 7.

[0035] Refer to the instruction manual appendix Figure 2 The top of the cabinet 1 has an air outlet 102, and a top cover 15 is fixedly connected to the air outlet 102.

[0036] It should be noted that the top cover 15 is square, with the bottom opening connected to the air outlet 102. The surrounding area is composed of baffles with multiple filter holes, and the top is sealed by the cover plate, so that the airflow can only flow out from the filter holes around the perimeter.

[0037] Working principle: When the height of the mounting bracket 7 needs to be adjusted, the knob 10 is manually turned, which drives the gear 9 on the rotating shaft 8 to rotate. Because the gear 9 meshes with the rack 5, the rotational motion is converted into linear motion, causing the mounting bracket 7 to move linearly along the rack 5. During this process, the slide groove 701 on the mounting bracket 7 slides on the guide rail 14 inside the cabinet 1, while the sliders 12 on both sides of the mounting bracket 7 slide along the guide rod 13 inside the cabinet 1, together guiding the mounting bracket 7 and preventing it from tipping over. The helical meshing of the gear 9 and the rack 5 also provides... The self-locking effect automatically locks the position when rotation stops. At the same time, temperature sensors 11 symmetrically arranged on both sides of the mounting bracket 7 monitor the temperature inside the cabinet in real time and transmit the signal to the PLC control system inside the cabinet 1. When the temperature rises, the control system starts the stepper motor 302 in the ventilation pipe 301. The stepper motor 302 drives the fan blade 303 to rotate, drawing in external cold air from the air inlet 101 at the bottom of the cabinet 1. The airflow flows from bottom to top through the heating elements, absorbs heat and becomes hot air, and finally is discharged from the air outlet 102 at the top of the cabinet 1.

[0038] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
