Description

Technical Field

[0001] This utility model relates to the technical field of PLC control cabinets, and in particular to a modularly assembled explosion-proof PLC control cabinet. Background Technology

[0002] An explosion-proof PLC control cabinet is a PLC control cabinet with explosion-proof function. Existing explosion-proof PLC control cabinets, such as the one disclosed in utility model patent CN219761684U and the one disclosed in utility model patent CN218163450U, can all achieve the explosion-proof effect.

[0003] However, during use, it was found that the electrical components in the existing explosion-proof PLC control cabinets are simply installed together, which makes them prone to complete damage in the event of an accident. Furthermore, modular installation and disassembly are inconvenient. In addition, when the cabinet door of the explosion-proof PLC control cabinet is opened during maintenance, all electrical components are exposed to the outside, resulting in poor explosion-proof performance. Therefore, there is an urgent need for a modularly assembled explosion-proof PLC control cabinet. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a modularly assembled explosion-proof PLC control cabinet that installs electrical components in a storage mechanism, dissipates heat from the electrical components through a heat dissipation mechanism, and provides explosion protection for the electrical components through the cooperation of the storage mechanism and the explosion-proof mechanism. In the event of flammable gas, a positive pressure mechanism maintains a positive pressure state within the explosion-proof mechanism to prevent flammable gas from entering the explosion-proof mechanism, thereby improving the practicality of the equipment.

[0005] This utility model discloses a modularly assembled explosion-proof PLC control cabinet, including an explosion-proof mechanism; it also includes a storage mechanism, a positive pressure mechanism, and a heat dissipation mechanism, wherein the storage mechanism and the positive pressure mechanism are both installed on the explosion-proof mechanism, and the heat dissipation mechanism is installed on the storage mechanism; The explosion-proof mechanism, in conjunction with the storage mechanism, provides explosion protection for the electrical components; the heat dissipation mechanism dissipates heat from the electrical components; and the positive pressure mechanism regulates the pressure within the explosion-proof mechanism. Electrical components are installed in the storage mechanism and cooled by a heat dissipation mechanism. The storage mechanism and the explosion-proof mechanism work together to protect the electrical components from explosion. In the event of flammable gas, a positive pressure mechanism maintains a positive pressure state within the explosion-proof mechanism to prevent flammable gas from entering the explosion-proof mechanism, thereby improving the practicality of the equipment.

[0006] Preferably, the explosion-proof mechanism includes an explosion-proof box, an explosion-proof door, and a conduit. The explosion-proof door is installed at the front of the explosion-proof box, and the conduit is installed at the rear of the explosion-proof box. The explosion-proof box and the explosion-proof door work together to protect the electrical components inside the storage mechanism from explosion. The conduit is used to run cables and signal lines into the explosion-proof box, thereby improving the practicality of the equipment.

[0007] Preferably, the conduit is a telescopic structure, and one end of the conduit is rotatably connected to the explosion-proof box. A limit bolt is provided on the conduit. According to the usage requirements, the conduit is rotated to adjust the position of the other end of the conduit, and the length of the conduit is adjusted by extending or retracting the conduit. After adjustment, the length of the conduit is locked by the limit bolt.

[0008] Preferably, the storage mechanism includes a drive motor, multiple sets of sprockets, a chain, multiple storage boxes, and multiple sets of casters. The drive motor is fixedly installed in an explosion-proof enclosure. Multiple sets of sprockets are rotatably installed in the explosion-proof enclosure, and the output end of the drive motor is connected to one set of sprockets. The chain is fitted onto the multiple sets of sprockets, and the multiple storage boxes are fixedly installed on the chain. Multiple sets of casters are respectively installed at the rear ends of the multiple storage boxes. Different electrical components are stored in the multiple storage boxes, and the multiple sets of casters support the multiple storage boxes, maintaining their stability. During maintenance, the drive motor is turned on, and the chain drives the multiple storage boxes through the multiple sprockets, moving the storage box requiring maintenance to the explosion-proof door. After maintenance, the drive motor reverses direction, resetting the multiple storage boxes, thereby improving the practicality of the equipment.

[0009] Preferably, the heat dissipation mechanism includes multiple sets of cooling fans, and the tops of the multiple storage boxes and the explosion-proof box are all provided with ventilation holes. The multiple sets of cooling fans are respectively installed on the multiple storage boxes. By operating the multiple sets of cooling fans, the air in the multiple storage boxes is replaced, thereby completing the heat dissipation of the electrical components.

[0010] Preferably, the positive pressure mechanism includes a mounting frame, a gas storage tank, a gas monitor, and a gas delivery pipe. The gas storage tank and the gas monitor are both mounted on the explosion-proof enclosure via the mounting frame. One end of the gas delivery pipe is connected to the gas storage tank via an explosion-proof solenoid valve, and the other end of the gas delivery pipe extends through the side wall of the explosion-proof enclosure to the bottom inside the enclosure. The gas monitor monitors the gas around the explosion-proof enclosure. When the gas monitor detects that the concentration of combustible gas exceeds a preset value, the explosion-proof solenoid valve on the gas delivery pipe opens, continuously releasing the inert gas from the gas storage tank into the explosion-proof enclosure, filling the enclosure with inert gas and preventing combustible gas from entering the enclosure, thereby improving the explosion-proof effect of the equipment.

[0011] Preferably, each of the multiple storage boxes is equipped with a display screen, and the explosion-proof door is equipped with a slide rail, on which an explosion-proof observation window is slidably installed. The operation data of the internal electrical components can be monitored through the display screen on the storage box. By opening the explosion-proof observation window and driving the motor, it is convenient for staff to observe the data on the display screen, thereby improving the practicality of the equipment.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the electrical components are installed in the storage mechanism and the heat dissipation mechanism dissipates heat from the electrical components. The storage mechanism and the explosion-proof mechanism work together to protect the electrical components from explosion. When flammable gas is present, the positive pressure mechanism maintains the positive pressure state in the explosion-proof mechanism to prevent flammable gas from entering the explosion-proof mechanism, thereby improving the practicality of the equipment.

The drive motor 5 is fixedly installed in the explosion-proof box 1. The multiple sets of sprockets 6 are all rotatably installed in the explosion-proof box 1, and the output end of the drive motor 5 is connected to one set of sprockets 6. The chain 7 is fitted onto the multiple sets of sprockets 6. The multiple sets of storage boxes 8 are all fixedly installed onto the chain 7.

Then, the explosion-proof door 2 is opened, and the drive motor 5 is activated. Through multiple sets of sprockets 6, the chain 7 moves the multiple storage boxes 8, moving the storage box 8 requiring maintenance to the explosion-proof door 2. After maintenance, the drive motor 5 reverses to reset the multiple storage tanks 8. During daily use, multiple cooling fans 10 run to replace the air in the multiple storage tanks 8, thereby cooling the electrical components.
