Description

Technical Field

[0001] This utility model relates to the field of power cabinet technology, specifically a fixed low-voltage partitioned power cabinet. Background Technology

[0002] A power distribution cabinet is a device used for power distribution and control, primarily used to distribute power to various electrical devices to ensure the stable operation of the power system. Power distribution cabinets typically integrate electrical components such as circuit breakers, contactors, and relays, enabling the protection, control, and monitoring of electrical equipment. Fixed low-voltage power distribution cabinets are widely used in industrial and commercial buildings, substations, and other locations, possessing good safety and reliability, and complying with relevant electrical standards.

[0003] Utility model patent CN217405944U discloses a fixed partitioned power cabinet, including a cabinet box, partition frames, and an inner shell. The cabinet box includes a shell and a cover. The cover is installed on the front end of the shell and is rotatably connected to the shell. The partition frames are evenly arranged on the inner side of the rear end of the shell and are fixedly connected to the shell. The inner shell is installed on the upper end of the partition frames and is rotatably connected to the partition frames. This ensures that the user can stably support and install the cabinet using a stabilizing base. This allows the cabinet to rotate flexibly on the stabilizing base, facilitating angle adjustment during maintenance. When maintenance is not required, pins passing through pin holes and mating holes can fix the stabilizing base and the shell together, ensuring the stability of the cabinet during use. After the cabinet is installed, the user can stably install the partition frames inside.

[0004] The aforementioned existing technology achieves the partitioned installation of the internal shell of the power cabinet through a partition frame, which can improve the utilization rate of internal space to a certain extent. However, when the internal shell is installed on the partition frame, the lack of an effective fixing structure, due to the rotatable connection between the fixing rod on the partition frame and the first rotating plate, and the rotatable connection between the first rotating plate and the second rotating plate, results in the partition frame not being able to guarantee the stability of the internal shell's position. This design makes the internal shell prone to displacement and shaking during use, which may cause the connecting wires of electrical components on the internal shell to become loose, or even lead to serious safety hazards such as short circuits. Therefore, to address this problem, we propose a fixed low-voltage partitioned power cabinet. This power cabinet significantly improves the stability of the internal shell by improving the partition structure and fixing method, ensuring the reliability of electrical component connections, thereby improving the safety and performance of the power cabinet.

[0021] Please see Figures 1-5 This utility model provides a technical solution: A fixed low-voltage partitioned power cabinet includes a power cabinet body 100. Fixed side plates 200 are provided on both the left and right sides of the inner wall of the power cabinet body 100. The fixed side plates 200 provide the mounting base and positioning function for a partition support plate 300. A partition support plate 300 is detachably connected between the two fixed side plates 200. The partition support plate 300 is used to divide the internal space of the cabinet and support electrical equipment. Multiple positioning holes 202 are provided on the opposite sides of the two fixed side plates 200 near the front, arranged at equal intervals. The positioning holes 202 are used to cooperate with positioning rods 430 to fix the partition support plate 300. Positioning components 400 are provided on the bottom of the partition support plate 300 near the left and right ends of the front side. The positioning components 400 are used to quickly lock or release the position of the partition support plate 300.

[0022] In this embodiment, a cabinet door 600 is hinged to the front side of the power cabinet body 100, and heat dissipation pipes 110 are provided through the left and right sides of the power cabinet body 100 and near the top. The heat dissipation pipes 110 are used to form heat dissipation channels.

[0023] Specifically, the heat pipe 110 is equipped with a cooling fan 500, which is connected to an external power supply and controller. The cooling fan 500 is used to force airflow to enhance heat dissipation efficiency, and the air outlet of the heat pipe 110 is equipped with a dust filter.

[0024] Furthermore, multiple sliding grooves 201 arranged at equal intervals on the opposite sides of the two fixed side plates 200 are provided. The sliding grooves 201 are used to guide the sliding strips 310 of the partition support plate 300 to move smoothly. A rubber liner 210 is provided inside the sliding grooves 201.

[0025] Furthermore, the left and right sides of the partition support plate 300 are provided with sliding strips 310. The outer side of the sliding strip 310 is in contact with the inner side of the rubber liner 210 to increase friction and prevent the partition support plate 300 from sliding outward or inward quickly during disassembly and assembly.

[0026] Furthermore, the positioning component 400 includes a rectangular hollow block 410 that is bolted to the bottom of the partition support plate 300, and the bottom of the rectangular hollow block 410 has a strip hole 411.

[0027] Furthermore, a T-shaped slider 420 is slidably connected inside the rectangular hollow block 410. The T-shaped slider 420 is used to drive the positioning rod 430 to insert into or disengage from the positioning hole 202 by sliding. The bottom end of the T-shaped slider 420 passes through the strip hole 411 and is fixedly connected to a push block 440. A finger groove 441 is provided on one side of the push block 440. The finger groove 441 is used to provide space for the fingers to apply force to facilitate the operation of the push block 440.

[0028] Furthermore, a positioning rod 430 is provided on the side of the T-shaped slider 420 near the fixed side plate 200. The end of the positioning rod 430 away from the T-shaped slider 420 passes through the inner wall of the rectangular hollow block 410 and is inserted into one of the positioning holes 202. The positioning rod 430 is used to insert into the positioning hole 202 to fix the position of the partition support plate 300.

[0029] Furthermore, a spring 450 is provided on the side of the T-shaped slider 420 away from the fixed side plate 200. The other end of the spring 450 abuts against the inner wall of the rectangular hollow block 410. The spring 450 is used to provide elastic restoring force for the T-shaped slider 420 to maintain the locked state of the positioning rod 430.

[0030] In this embodiment, when using the fixed low-voltage partitioned power cabinet, firstly, the partition support plate 300 is moved vertically along the fixed side plate 200 to the required height. Through the cooperation of the sliding groove 201 and the sliding strip 310, the friction between the sliding strip 310 and the rubber liner 210 during the sliding process can prevent the partition support plate 300 from sliding rapidly. Then, press the finger groove 441 on the push block 440 to push the T-shaped slider 420 to compress the spring 450 and drive the positioning rod 430 to retract. After the partition support plate 300 is adjusted to the position, release the push block 440, and the spring 450 will retract. The positioning rod 430 is driven by the reset force to be inserted into the positioning hole 202 at the corresponding height, thus fixing the partition support plate 300. After the partition support plate 300 is fixed, the user can fix the vertical plate for installing electrical equipment to the surface of the partition support plate 300 with bolts, and install electrical equipment and connecting lines. When the power cabinet is running, the cooling fan 500 starts and exhausts hot air from the heat dissipation pipe 110. When maintenance or adjustment of the internal layout is required, the partition support plate 300 can be quickly disassembled or repositioned by repeatedly pressing the push block 440 to unlock the positioning component 400.
