[0035] Specific implementation: In the initial state, the limit rod 6 is inserted into the limit hole 27 on the flame-retardant plate 5 through the guide sleeve 7, so that the flame-retardant plate 5 is placed in the heat dissipation hole under the action of the limit rod 6 2 On the upper side, when the PLC controls the electromagnet 9 to be energized, the electromagnet 9 generates magnetism that attracts the permanent magnet 8, and under the action of mutual attraction, the permanent magnet 8 moves toward the electromagnet 9, so that the limit rod 6 is disengaged The limit hole 27 realizes that the limit component loses the restriction on the position of the flame-retardant plate 5. When a fire breaks out in the space formed by the cabinet body 1 and the cabinet door 3, the probe 11 transmits the monitored information to the PLC, and the PLC controls the limit The positioning component moves, so that the limiting component loses its limiting effect on the flame-retardant plate...
