[0022] PLC control system is a new generation of industrial control device formed by introducing microelectronic technology, computer technology, automatic control technology and communication technology on the basis of traditional sequential controller. Its purpose is to replace relays, execution logic, timing, counting and other sequential control functions, and establish a flexible remote control system.

[0023] There are many precision components in the control box equipped with the PLC control system, which will generate a lot of heat during operation. If this heat is not discharged in time, it will cause temperature imbalance in the PLC control box and cause damage to the components.

[0024] When the PLC control box is operating normally, the hot air generated by its internal components will float up. When the temperature reaches the standard, the temperature sensor in the PLC control box transmits a signal to the fan heat dissipation component 21, the fan heat dissipation component 21 is turned on, and then the floating hot air is discharged through the inclined heat dissipation port 22, thereby reducing the temperature in the PLC control box. After long-term use, when the dust accumulation on the dustproof net 23 needs to be cleaned, the switch door 3 is opened, and then the dustproof net 23 is pulled out, and the connecting slider 24 slides in the connecting slide groove 13 until the dustproof net 23 leaves the connecting groove 12;

[0025] The principle that hot air floats can be used to better discharge the heat generated by the operation of the PLC control box, avoiding heat accumulation in the PLC control box that affects the normal operation of the components in the PLC control box, and effectively ensuring the service life of the PLC control box. The PLC control box is also equipped with a temperature sensor, which makes the opening and closing of this mechanism more intelligent and easier to use.
