Description

Technical Field

[0001] This utility model relates to the field of electrical safety technology, specifically a safety distribution cabinet for the production of hazardous chemicals. Background Technology

[0002] Safety distribution cabinets for hazardous chemical production are designed specifically for high-risk environments. They are made of explosion-proof and fire-resistant materials and integrate multiple protection mechanisms to ensure a stable power supply and the safety of personnel and equipment. They have high corrosion resistance, sealing and intelligent monitoring functions, and are an indispensable safety guarantee equipment in chemical production.

[0003] Chemical production processes typically require substantial electrical power to power various mechanical equipment, control automated systems, and ensure lighting. Therefore, safety-grade distribution cabinets are essential. However, traditional distribution cabinets often have their heat dissipation grilles tightly integrated with the cabinet structure, forming a unified cooling system. While this design improves heat dissipation efficiency, it also increases the difficulty of disassembly. The inconveniently disassembled grilles make cleaning and maintenance difficult, potentially leading to a continuous decline in heat dissipation performance. This, in turn, affects the normal operation of the distribution cabinet. Poor heat dissipation causes the internal temperature of the distribution cabinet to rise, accelerating the aging of electrical components and reducing their insulation performance.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 As shown, a safety distribution cabinet for hazardous chemical production includes a cabinet body 1. The cabinet body 1 facilitates the installation of mounting frames 3. The cabinet body 1 is welded from special carbon steel or cold-rolled steel plate. A heat dissipation mesh 2 is provided on one side of the cabinet body 1 to facilitate ventilation and heat dissipation inside the cabinet body 1. Multiple sets of mounting frames 3 are fixedly connected to the inner wall of the cabinet body 1. The mounting frames 3 facilitate the installation of fixing rods 4. The fixing rods 4 are snapped into the inner wall of the mounting frames 3. For ease of installation, the circuit breaker 5 is fixedly connected to the outside of the fixing rod 4. The circuit breaker 5 operates based on the thermomagnetic tripping principle. When the current in the circuit exceeds a set value, the heating element heats up and bends, pushing the tripping mechanism to cut off the circuit. It is also equipped with a magnetic trip unit, which quickly cuts off the circuit in case of a short circuit. It should be noted that the circuit breaker 5 is existing technology and will not be elaborated further. A contactor 6 is fixedly connected to the outside of the fixing rod 4. When the coil is energized, a magnetic field is generated that attracts the moving iron core, driving the contact system. The action causes the main contacts to close, the auxiliary normally open contacts to close, and the auxiliary normally closed contacts to open. When the coil is de-energized, the magnetic field disappears, the spring causes the contacts to return to their original position, and the power supply is cut off. It should be noted that contactor 6 is existing technology and will not be described in detail here. A relay 7 is fixedly connected to the inner wall of cabinet 1. Relay 7 is a switching device that uses electromagnetic principles to control the circuit. When the coil is energized, it generates a magnetic field that attracts the contacts to close or open, thereby controlling the circuit. It consists of a coil, iron core, contacts, and a housing. It should be noted that the relay... 7 is existing technology and will not be described in detail here. A disassembly mechanism 8 is set on one side of the heat dissipation mesh 2 to facilitate the disassembly of the heat dissipation mesh 2. The disassembly mechanism 8 includes a positioning plate 81 fixed to the inner wall of the cabinet 1. By setting the positioning plate 81, the limiting block 82 can be easily engaged. The inner wall of the positioning plate 81 is engaged with the limiting block 82. By setting the limiting block 82, the connecting ring 83 can be easily connected. The top of the limiting block 82 is fixedly connected to the connecting ring 83. By setting the connecting ring 83, the mounting plate 12 can be easily connected.

[0023] A fixing block 9 is fixedly connected to one side of the heat dissipation mesh 2. By setting the fixing block 9, the connecting plate 10 can be easily fixed. Multiple sets of connecting plates 10 are fixedly connected to one side of the fixing block 9. By setting the connecting plates 10, the connecting column 11 can be easily rotated. The inner wall of the connecting plate 10 is fixedly connected to the connecting column 11. By setting the connecting column 11, the mounting plate 12 can be easily rotated. The number of connecting columns 11 is set to two sets. One end of the connecting column 11 is rotatably connected to the mounting plate 12. By setting the mounting plate 12, the connecting ring 83 can be easily connected. One side of the mounting plate 12 is fixedly connected to one side of the connecting ring 83. A limiting spring 13 for resetting the connecting ring 83 is fixedly connected to the bottom of the connecting ring 83.

[0024] The inner wall of the mounting frame 3 is fitted with a cable tray 14 for organizing the wiring, and the number of cable trays 14 is set to six. The inner wall of the mounting frame 3 is fitted with a connecting rod 15. By setting the connecting rod 15, the placement plate 16 can be easily fixed. The top of the connecting rod 15 is fixedly connected to the placement plate 16 for placing chemicals.

[0025] Working principle: During use, the circuit breaker 5 protects the circuit through steps such as energy storage, closing preparation, closing, closing holding, and opening. When the current is abnormal, it trips, the contactor 6 and the coil are energized to attract the armature, causing the contacts to close and be energized. When the power is off, the spring resets, the contacts open, the coil is energized to generate magnetic force to attract the armature, causing the contacts to close or open, controlling the load circuit. The internal heat is dissipated through the heat dissipation mesh 2. When it is necessary to disassemble the heat dissipation mesh 2, the connecting column 11 rotates on the inner wall of the connecting plate 10. The rotation of the connecting column 11 will drive the mounting plate 12 to rotate. When the mounting plate 12 rotates, it can drive the connecting ring 83 to rotate, and the limit spring 13 resets the connecting ring 83, pulling open the two sets of limit blocks 82 respectively, releasing the limit on the positioning plate 81, thereby disassembling the heat dissipation mesh 2.
