AI Technical Summary
When the PLC control system is adjusted in the anti-interference box, it is prone to shaking, which can cause damage to the internal structure. Existing anti-interference equipment cannot effectively protect the PLC control system.
An anti-interference device was designed, comprising an anti-interference box, a limit block, an air-cooling device, a rotating tube, a jacket, and a clamping plate structure. The rotating tube dissipates heat, the jacket stabilizes the PLC control system, the clamping plate buffers impacts, and the air-cooling device regulates the temperature, preventing the PLC control system from shaking and being damaged inside the anti-interference box.
It improves the anti-interference performance of the PLC control system, reduces the damage to the equipment during impact, ensures the stability and heat dissipation of the system, and enhances the protection performance.
