[0028] Working principle: When encountering rainy weather, the outside temperature is low, at this time the temperature inside the cabinet 1 is normal, the thermal bimetallic strip 24 is in a straight state, at this time the bottom of the top plate 27 is in contact with the top of the cabinet 1, the cabinet 1 is sealed to prevent moisture from entering the inside of the cabinet 1, the frame 26 is inside the cabinet 1, when the internal temperature of the cabinet 1 rises, the thermal bimetallic strip 24 is heated and bends toward the passive layer direction of the thermal bimetallic strip 24, that is, bends upward, thereby driving the bottom plate 25 to move upward, and then moving the frame 26 upward, so that the heat dissipation holes at the upper end of the frame 26 are in contact with the outside world, and the natural wind from the outside is first Under the action of the guide plate 211 and the sunshade 212, the natural wind will enter the interior of the frame 26 through the heat dissipation holes. At this time, the wind vane 29 drives the rotating shaft 28 to rotate, so that the baffle 210 is opposite to the wind direction, so that the natural wind entering the frame 26 flows downward and will not be discharged from the heat dissipation holes at the rear. The natural wind entering the bottom of the frame 26 will be discharged through the heat dissipation holes at the lower end of the frame 26 to the interior of the cabinet 1. The natural wind will blow to the second guide plates 215 on both sides and will blow downward along the second guide plates 215 through the ventilation slots 214 to the bottom of the partition 21, so as to dissipate heat for the electronic components inside the cabinet 1. 1, the higher the temperature inside, the greater the bending degree of the thermal bimetallic strip 24, so that the heat dissipation holes on the frame 26 are in contact with the outside world, so that the heat dissipation effect is better. When a fire occurs inside the cabinet 1, the temperature of the inner wall of the cabinet 1 rises rapidly. At this time, the thermal bimetallic strip 24 drives the bottom plate 25 to rise, so that the bottom plate 25 contacts the bottom of the partition 21, and at the same time, the inclined block 219 is pushed to move to both sides through the rods 220 on both sides of the bottom plate 25, thereby driving the sliding frame 218 to move to both sides and close the ventilation slot 214. At this time, the space below the partition 21 is in a sealed state, and at the same time, the movement of the sliding frame 218 will drive the moving rod 5 to move. The second switch 7 is moved, thereby opening the second switch 7, and the second switch 7 controls the electromagnetic valve 33 and the electric push rod 34 to start. The electromagnetic valve 33 is opened, and the nitrogen in the nitrogen bottle 31 is blown into the interior of the cabinet 1 through the outlet pipe 32 to extinguish the fire. At the same time, the electric push rod 34 drives the first mobile frame 35 to rise and fall. The lifting of the first mobile frame 35 will drive the rotating rod 37 to rotate through the rack 36 and the gear 38, and then drive the third guide plate 39 to swing, so that the nitrogen blown out of the outlet pipe 32 is evenly distributed inside the cabinet 1, thereby improving the fire extinguishing effect. When the temperature inside the cabinet 1 drops, the thermal bimetallic strip 24 will reset, thereby realizing recycling.

[0029] It is worth noting that the active layer material of the thermal bimetallic strip 24 of the present application is manganese-nickel-copper alloy, and the passive layer material is Invar alloy. The manganese-nickel-copper alloy has a higher expansion coefficient, while the Invar alloy has a lower expansion coefficient, so that it can bend and deform upward when the temperature in the distribution cabinet rises.

[0030] See also Figure 1-12 On the basis of the above embodiment, in another embodiment of the present invention, preferably, a cooling mechanism 4 is provided inside the cabinet 1, and the cooling mechanism 4 includes a guide rail 41, a linear motor 42, a second movable frame 43, and a cooling fan 44. The guide rails 41 are arranged on both sides of the inner wall of the cabinet 1, the linear motor 42 is arranged on the guide rails 41, the second movable frame 43 is fixedly connected to the linear motor 42, the cooling fan 44 is fixedly installed on the inner side of the second movable frame 43, and the number of the cooling fans 44 is two, and they are symmetrically arranged on the inner side of the second movable frame 43.

[0031] Working principle: When the interior of the cabinet 1 cannot be completely cooled by natural heat dissipation, the bending of the thermal bimetallic strip 24 will initially push the sliding frame 218 through the support rod 220 and the inclined block 219, so that the moving rod 5 slides over the first switch 6 and is between the first switch 6 and the second switch 7, so that the first switch 6 is opened, and the first switch 6 will start the linear motor 42 and the cooling fan 44, the linear motor 42 drives the second moving frame 43 to move up and down, and then starts the cooling fan 44 to cool the electronic components inside the cabinet 1, thereby improving the operating stability of the electronic components.
