Protection device for network security control equipment

The invention belongs to the technical field of network equipment protection, and relates to a protection device for network security control equipment. The protection device comprises a cabinet; the cabinet comprises a shell, a cooling mechanism, an electromagnetic shielding plate, a support plate, a chute and a temperature controller; and the cooling mechanism is mounted at the bottom in the shell. The cooling mechanism is adopted, the temperature controller controls the cooling mechanism to operate, the cooling mechanism generates cold air, the cold air is blown to the network security control equipment on a tray in a close range, so that the cooling of the network security control equipment and environment cooling in the whole shell are achieved; and when the operating environment of the network security control equipment is higher than a borne range temperature, the network security control equipment is cooled in time, and the working time of the equipment in a high-temperature state is shortened, so tha
