Technical Field

The utility model relates to the technical field of outdoor waterproof ventilation PLC control cabinet structures, in particular to an outdoor waterproof ventilation PLC control cabinet structure.

Background technique

The outdoor waterproof ventilation PLC control cabinet structure refers to a complete set of control cabinets, which are electrical cabinets that can realize the control of motor switches. The outdoor waterproof ventilation PLC control cabinet structure has protection functions such as overload, short circuit, and phase loss protection. It has a compact structure, stable operation, and complete functions. It can be combined according to the actual control scale. It can realize single-cabinet automatic control and multiple cabinets through industrial Ethernet or industrial field bus network to form a distributed control system. The outdoor waterproof ventilation PLC control cabinet structure can adapt to various industrial automation control occasions of various sizes and is widely used in electric power, metallurgy, chemical industry, papermaking, environmental protection, sewage treatment and other industries.

After searching, the Chinese patent application number 202121713599.5 discloses a waterproof outdoor waterproof ventilated PLC control cabinet structure.

The beneficial effect is that the utility model is a waterproof outdoor waterproof ventilation PLC control cabinet structure. Due to the use of a protective shell, vents, L-shaped air inlet pipe, exhaust fan, awning, telescopic hose and buffer assembly, compared with the prior art, the interior of the cabinet is divided by the protective shell. When the exhaust fan is used for heat dissipation, the protective shell plays a waterproof role, which plays a good waterproof role and prevents rainwater from entering the protective shell through the L-shaped air inlet pipe.
