[0055] like Figures 1 to 9 As shown, a metering meter 3 box with an alarm function includes a box body 1 and a box door 2, wherein the box body 1 and the box door 2 are hingedly arranged, and a plurality of electric meters 3 distributed in a rectangular array are installed inside the box body 1, and a plurality of isolation chambers 4 are arranged inside the box body 1, and the front of each isolation chamber 4 is tightly fitted with the box door 2, and each of the electric meters 3 is correspondingly installed in the isolation chamber 4, and an alarm 5 and a short-circuit monitoring component are arranged inside the box body 1, one end of the short-circuit monitoring component is electrically connected to the alarm 5, and the other end is electrically connected to all the electric meters 3, and a plurality of ventilation holes corresponding to all the electric meters 3 are arranged on the box door 2, and a plurality of transparent flaps 6 are rotatably connected in each of the ventilation holes, and a fire extinguishing component is arranged in each of the isolation chambers 4, and each of the fire extinguishing components is respectively connected to all the transparent flaps 6 in one of the ventilation holes in a transmission manner.

[0056] For example, the short-circuit monitoring component is used to monitor and protect the line of the electric meter 3 in the box 1. When a short circuit occurs in the electric meter 3, the short-circuit monitoring component is used to operate the alarm 5 to remind the staff to come for repair in time. When the electric meter 3 catches fire due to other faults, the fire extinguishing component is used to first control the transparent flap 6 to flip and combine to close the vent, so that the isolation chamber 4 is in a sealed environment, and then inert gas is introduced to extinguish the fire. The isolation chamber 4 is independent and will not affect the operation of other electric meters 3. The transparent flap 6 is made of transparent material and is used to observe the data on the electric meter 3, which is convenient for the staff to read the meter.

[0057] As an optional embodiment, the plurality of isolation chambers 4 are formed by integrally forming a plurality of transverse isolation plates and a plurality of longitudinal isolation plates, each of the transverse isolation plates and the longitudinal isolation plates are made of refractory materials, and the interior of each of the transverse isolation plates and the longitudinal isolation plates is a cavity that is interconnected.

[0058] As an optional embodiment, the short circuit monitoring component includes:

[0059] A start switch 7 is fixedly mounted in the box 1;

[0060] A fixing plate 8 is arranged at the driving part of the start switch 7, and a plurality of pull rods 9 corresponding to all the electric meters 3 are passed through the fixing plate 8, and a start block 10 is fixed at one end of each pull rod 9 close to the start switch 7;

[0061] A plurality of springs 11 are respectively sleeved on the pull rod 9, and two ends of each spring 11 are respectively pressed against the start block 10 and the fixed plate 8;

[0062] A plurality of electromagnets 12 are respectively fixed in the isolation chamber 4, and each of the electromagnets 12 is respectively electrically connected to the electric meter 3;

[0063] A plurality of pull wires 13 are arranged in the cavity, one end of each pull wire 13 passes through the cavity and is fixedly connected to one end of the pull rod 9 away from the start block 10, and the other end passes through the cavity and is fixedly provided with an iron block 14, each of which is adsorbed on the electromagnet 12;

[0064] A plurality of signal lights 15, each corresponding to an electric meter 3, are arranged on the box door 2, each of the signal lights 15 is electrically connected to a signal switch 16, each of the signal switches 16 is respectively arranged on a side of the iron block 14 away from the electromagnet 12, and each of the signal switches 16 is respectively fixedly connected to the isolation chamber 4;

[0065] A plurality of fuse structures 17 are respectively arranged in the isolation chamber 4 , and one end of each of the fuse structures 17 is electrically connected to the electromagnet 12 , and the other end is connected to an external circuit.

[0066] For example, when a short circuit occurs in the circuit of the electric meter 3, the circuit is first disconnected by the fuse structure 17, the electromagnet 12 is powered off and loses its magnetism, the iron block 14 is released, and under the action of the spring 11, the starting block 10 is pushed to contact the starting switch 7, so that the starting switch 7 is turned on, and the alarm 5 works to remind the staff. At the same time, the pull rod 9 is affected by the spring 11, and the pull wire 13 is controlled to pull the iron block 14 to move the iron block 14 and act on the signal switch 16 to control the signal light 15 to light up, thereby reminding the staff of the location of the faulty electric meter 3.

[0067] As an optional embodiment, the two ends of the transparent flip plate 6 are respectively provided with a protrusion 18 and a groove 19 that are adapted to be connected, the inner side of the groove 19 is provided with an extrusion port 20, and one side of the protrusion 18 is provided with a rubber strip 21 that is adapted to the extrusion port 20, and the structure at the top and bottom of the vent is adapted to be connected with the structure at both ends of the transparent flip plate 6.

[0068] For example, by providing matching protrusions 18 and grooves 19 on each transparent flap 6, and providing rubber strips 21 and extrusion openings 20 on the protrusions 18 and grooves 19, the sealing state of the vents can be further improved.

[0069] As an optional embodiment, the fire extinguishing assembly includes:

[0070] A mounting groove 22 is arranged beside the vent, and a shaft of the transparent flap 6 passes through the mounting groove 22 and is fixed with a first gear 23;

[0071] A first rack 24, slidably connected and disposed in the mounting groove 22, wherein the first rack 24 is meshed with the first gear 23;

[0072] A driving rod 25 is fixedly mounted on a side of the first rack 24 close to the isolation chamber 4;

[0073] A flame driving assembly, one end of which is arranged at the inner top of the isolation chamber 4, and the other end of which is arranged at the bottom of the driving rod 25;

[0074] An air storage box 26 is fixedly mounted on the inner top of the box body 1;

[0077] A plurality of jet valves 30 are respectively arranged on the second air pipe 29, each of the jet valves 30 is provided with a valve stem 31, each of the valve stems 31 is transmission-connected with a linkage assembly, and each of the linkage assemblies is transmission-connected with the flame driving assembly;

[0078] After the electric meter 3 catches fire, the flame spreads to the flame driving assembly, causing the flame driving assembly to work and drive the driving rod 25 to move, so as to complete the vent sealing work.

[0079] For example, an inert gas is injected into the gas storage box 26. When the electric meter 3 catches fire due to a malfunction, the flame spreads to the flame drive assembly, causing the flame drive assembly to work and drive the drive rod 25 to move. The drive rod 25 drives one end of the first rack 24, the first rack 24 drives the first gear 23 to rotate, and the first gear 23 drives the transparent flap 6 to rotate to complete the vent sealing work. The flame drive assembly drives the linkage assembly to work, so that the linkage assembly controls the valve stem 31 to rotate to open the injection valve 30. At this time, the air pump 27 works to introduce the inert gas in the gas storage box 26 into the first air pipe 28, and then into the second air pipe 29 through the first air pipe 28, and acts on the corresponding isolation chamber 4 through the corresponding injection valve 30 to perform fire extinguishing work.

[0083] The weight block 34 is hung on an end of the connecting arm 33 away from the driving rod 25 .

[0084] For example, when the electric meter 3 catches fire, the flame spreads to the magnesium bar 32, and the magnesium bar 32 is melted by the flame, thereby releasing the weight 34, and the weight 34 drives the connecting arm 33 to rotate, so that one end of the connecting arm 33 pushes the driving rod 25 to move, thereby completing the sealing work of the vent.

[0085] As an optional embodiment, the linkage component includes:

[0086] A second gear 35, sleeved on the connecting shaft, and the second gear 35 is fixedly connected to the connecting shaft;
