The lifting blocking device 14 corresponds to the power cord 17 of the outlet opening 12. Meanwhile, a fire sensing device 13 is also provided on the side where the lifting blocking device 14 is located. The fire sensing device 13 is used to sense whether there is a fire in the box 10. When a fire occurs, the fire sensing device 13 is triggered to drive the lifting blocking device 14 to lift and cut off the power supply of the power cord 17, thereby preventing the fire inside the box 10 from spreading outward along the power cord 17.

[0028] It should be noted that the fire sensing device 13 includes but is not limited to photoelectric smoke and light electric sensor, thermistor sensor, infrared sensor, gas sensor, etc.

[0029] Further, the lifting blocking device 14 comprises a blocking knife 141 and a lifting mechanism 145, the blocking knife 141 is slidingly arranged in the side wall of the box body 10 provided with the wire outlet 12 and corresponds to the wire outlet 12, the blocking knife 141 is connected with the lifting mechanism 145, the lifting mechanism 145 is located below the blocking knife 141 and is used for driving the blocking knife 141 to rise or fall;

[0030] Specifically, the lifting blocking device 14 comprises a blocking knife 141 and a lifting mechanism 145, the side wall of the box body 10 provided with the wire outlet 12 is provided with a cavity 11, the power cord 17 passes through the cavity 11, the blocking knife 141 is slidingly arranged in the cavity 11 and is located below the power cord 17, the lifting mechanism 145 is fixedly arranged in the bottom of the cavity 11, and the output end of the lifting mechanism 145 is connected with the blocking knife 141, when the lifting mechanism 145 operates, the blocking knife 141 is driven to rise, and in the rising process of the blocking knife 141, the power cord 17 is cut, so that the power cord 17 is disconnected, thereby avoiding the spread of fire along the power cord 17.

[0031] Further, in the embodiment, the blocking knife 141 is provided with a plurality of blocking knives 141, the blocking knife 141 corresponds to the number of the power cord 17, in order to ensure the synchronous movement of the plurality of blocking knives 141, the plurality of blocking knives 141 are fixedly connected together through a synchronous support 146, and the blocking knife 141 located at the bottom is in transmission connection with the lifting mechanism 145, when the lifting mechanism 145 operates, the blocking knife 141 connected with the lifting mechanism 145 is driven to move, and other blocking knives 141 are synchronously driven to move, so that the plurality of blocking knives 141 synchronously cut the power cord 17.

[0032] It should be noted that the number of the blocking knife 141 is determined according to the number and arrangement of the wire outlet 12, when the wire outlet 12 is arranged side by side, the blocking knife 141 can be provided as one; when the wire outlet 12 is arranged in parallel, the blocking knife 141 is provided with a plurality of blocking knives 141, and the plurality of blocking knives 141 correspond to the power cord 17 one by one.

[0034] Further, although the power line 17 is cut off, the spread path of the fire is also cut off, but the outlet 12 and the cut of the power line 17 can contact the box 10, which can cause a short circuit and aggravate the fire. To avoid this situation, an insulating piece 142 is arranged at the bottom of each blocking knife 141. When the blocking knife 141 rises to the limit position, the power line 17 is cut off, and the cut of the power line 17 contacts the insulating piece 142, and the outlet 12 is blocked by the insulating piece 142, so as to avoid aggravating the fire or the fire spreading out of the box 10. In addition, the arrangement of the insulating piece 142 can also avoid the conduction of the current of the power line 17 to the box 10, so as to avoid electric shock when the fire extinguishing personnel extinguishes the fire, and improve the safety of the equipment. The insulating piece 142 needs to have a high melting point to avoid being melted under the fire.

[0035] Further, the bottom of the insulating piece 142 is also provided with a receiving strip 143, and the bottom of the receiving strip 143 is also provided with a groove 144 matched with the cutting edge of the blocking knife 141.

[0036] Further, in order to make the blocking knife 141 rise and fall linearly, guide rods 15 are fixedly connected to both ends of the insulating piece 142 at the bottom. One end of the guide rod 15 away from the insulating piece 142 is slidably connected to the bottom of the cavity 11 of the box 10, so that the lifting mechanism 145 linearly rises or falls when driving the blocking knife 141 to move.

[0037] Further, since the lifting mechanism 145 is located in the box 10, when the internal temperature of the outlet fire in the box 10 is too high, in order to avoid the high temperature affecting the operation of the lifting mechanism 145, a high-temperature protection shell 16 is arranged outside the lifting mechanism 145 to avoid the high temperature affecting the normal operation of the lifting mechanism 145. The lower part of the high-temperature protection shell 16 is a metal cover plate of the box 10, which is detachably arranged to facilitate regular detection of the lifting mechanism 145, so as to prevent the lifting mechanism 145 from failing to normally drive in case of fire.

[0038] It should be noted that the lifting mechanism 145 adopts a stepping motor, which is convenient for controlling the movement stroke of the blocking knife 141.

[0039] In summary, the fire disaster sensing device is arranged in the power supply and distribution integrated box to monitor whether the fire disaster occurs in the box in real time. The lifting blocking device is arranged in the power supply and distribution integrated box, so that the power line can be cut off in time when the fire disaster occurs in the power supply and distribution integrated box, the fire disaster can be prevented from spreading along the power line, the fire disaster risk is reduced, the current of the power line is effectively prevented from being conducted to the box by the insulating piece, and the working safety of the fire extinguishing personnel is improved.
