[0035] In a preferred embodiment, the first connecting plates 322 are provided in a plurality of numbers and the first connecting plates 322 are evenly arranged inside the box body 1. A round rod 4 is provided inside the first connecting plate 322 and the first connecting plate 322 is rotatably connected to the round rod 4.

The number of the first connecting plates 322 corresponds to the number of the dry powder storage bottles 32, and a feeding tube 5 is installed on the top of the dry powder storage bottle 32, and the feeding tube 5 extends to the outside of the box body 1. The device sets the first connecting plates 322 in a plurality of numbers and makes the first connecting plates 322 correspond to the dry powder storage bottle 32 so that the sealing plug 321 on the first connecting plate 322 can be inserted into the dry powder storage bottle 32 to seal the dry powder storage bottle 32 and prevent the dry powder from being spilled at will. At the same time, a feeding tube 5 is also installed on the dry powder storage bottle 32 so that the dry powder can be replenished after the dry powder is used up and can be used later.

[0037] In a preferred embodiment, the interior of the hollow cylinder 33 is set to be hollow, and the first spring 9 is stably connected inside the hollow cylinder 33, one end of the first spring 9 is fixedly connected to the push rod 331, and a rectangular groove 10 is also opened on the inner wall of the box body 1, and the second spring 11 is stably installed inside the rectangular groove 10, and a holding plate 12 is fixedly installed on one end of the second spring 11 for limiting the push rod 331, and a pull rope 13 is installed outside the holding plate 12. The device is installed with a hollow cylinder 33 inside the box body 1, and a slidable push rod 331 is arranged inside the hollow cylinder 33, and the push rod 331 can be pushed to push the first connecting plate 322, so that the sealing plug 321 can be pulled out from the inside of the dry powder storage bottle 32, which is convenient for discharging the dry powder. When not in use, the push rod 331 can be squeezed and limited by the holding plate 12 so that it will not push the first connecting plate 322, so that the dry powder can be prevented from being scattered at will.

[0038] The electronic components inside the box 1 will generate a lot of heat when working normally. If the heat is not dissipated in time, it will not only affect the use effect of the electronic components, but also easily cause danger. Therefore, a heat dissipation mechanism 14 is also installed inside the box 1. The heat dissipation mechanism 14 includes an electric telescopic rod 141, an air outlet cover 142 and an infrared sensor 143. The infrared sensor 143 is stably installed on the inner wall of the box 1, and a transparent tube 15 is stably installed on the inner bottom of the box 1, and mercury is placed inside the transparent tube 15. The infrared sensor 143 is arranged above the transparent tube 15. An air outlet hole 16 is opened on the top of the box 1, and a vertical rod 17 is fixedly installed at a position around the air outlet hole 16. A third spring 18 is stably installed inside the vertical rod 17. A support rod 19 is fixedly installed at one end of the third spring 18. One end of the support rod 19 The end is connected to the air outlet hood 142, the air outlet hood 142 covers the air outlet 16, the electric telescopic rod 141 is stably installed at the top position inside the box body 1, the telescopic end of the electric telescopic rod 141 is installed with a second connecting plate 20, and a pushing rod 21 is stably installed on the upper surface of the second connecting plate 20, the upper end of the pushing rod 21 is set at the position inside the air outlet hood 142, the infrared sensor 143 is electrically connected to the PLC controller 25, the PLC controller 25 is electrically connected to the electric telescopic rod 141 and the vacuum pump 22, the outer surface of the box body 1 is fixedly installed with a control box 26, the PLC controller 25 is arranged inside the control box 26, a sliding block 27 is slidably installed inside the transparent tube 15, and a stopper 28 is installed on the upper surface of the sliding block 27, the transparent tube 15 is set in the shape of a cylinder, and a surrounding plate is installed on the top of the transparent tube 15 to limit the sliding block 27.

[0039] During actual use, the heat inside the box 1 continues to rise, causing the mercury to expand and move continuously upward inside the transparent tube 15. As the temperature inside the box 1 continues to rise, the expansion effect on the mercury becomes more obvious, which causes the mercury to push the sliding block 27 and drive the ruler 28 to move upward. The device sets the mass of the sliding block 27 and the ruler 28 to 2g, which is very light, making it convenient for mercury to push the sliding block 27 and move one end of the ruler 28 to the position of the infrared sensor 143. The presence of the ruler 28 is detected by the infrared sensor 143, and the electric telescopic rod 141 can be controlled to work through the PLC controller 25.

[0040] The retraction of the telescopic end of the electric telescopic rod 141 will drive the second connecting plate 20 to move upward, and drive the pushing rod 21 to move upward, and the air outlet hood 142 will be pushed upward by the pushing rod 21. Since the air outlet hood 142 is stably connected to the support rod 19, this will limit the air outlet hood 142. When the air outlet hood 142 is pushed upward, a gap can be left, and the hot air inside the box body 1 will be discharged to the outside from the position of the gap, so as to cool the inside of the box body 1.

[0041] In order to quickly dissipate the heat inside the box 1, an exhaust fan 22 is stably installed on the top of the box 1, an intake pipe 23 is stably installed at the air inlet end of the exhaust fan 22, and one end of the intake pipe 23 is set inside the box 1, and a pipe 24 is installed at the air outlet end of the exhaust fan 22, one end of the pipe 24 is also installed inside the box 1, and one end of the pipe 24 is set at the bottom end of the box 1.

[0042] During actual use, the vacuum fan 22 will extract the gas inside the box 1 and transport the gas to the inside of the pipe 24. The gas inside the pipe 24 will be passed into the inside of the box 1 again, accelerating the fluidity of the gas inside the box 1 and accelerating the discharge of the gas from the gap position, so as to discharge the hot air inside the box 1 and cool down the inside of the box 1 in time to ensure that the electronic components inside the box 1 can be used normally.

[0043] Specifically, the working process or working principle of an automatic monitoring device for an electronic engineering cabinet is as follows: a large number of electronic devices will be installed inside the electronic engineering cabinet, such as circuit boards, power modules, relays, contactors, etc. These electronic devices are centrally installed inside the electronic engineering cabinet. When the electronic engineering cabinet is in normal use, these electronic devices will generate a certain temperature. As the temperature continues to rise, it will affect the working performance of the electronic equipment, and as the temperature rises, it is easy to cause a short circuit in the circuit. Once a short circuit occurs in the circuit, it is easy to cause a fire. Moreover, when the electronic engineering cabinet is in use, the cabinet door is in a closed state. When a fire occurs, it cannot be discovered in time, which will lead to a larger fire and cause danger. Therefore, this device is designed to solve this problem.

[0044] The present invention can monitor the fire situation inside the box body 1, and can timely extinguish the fire when a fire occurs to avoid causing greater losses. The specific operation is to stably place the present invention in a horizontal position for use and connect it to an external power supply. Since a plurality of electronic components are installed inside the box body 1, when these electronic components work at the same time, the load of the circuit will increase. When the circuit is aged, it is difficult for the circuit to bear the load of each component working at the same time, and a fire is likely to occur. In the event of a fire, smoke is generated inside the box body 1, and the pull rope 13 will be burned when the flame burns. At this time, the pull rope 13 can no longer pull the holding plate 12. The holding plate 12 can drive the holding plate 12 to move back to the inside of the rectangular groove 10 under the retraction of the second spring 11. At the same time, the push rod 331 will move upward under the push of the first spring 9. The push rod 331 will have a certain thrust under the push of the first spring 9, which will push the first connecting plate 322, so that the first connecting plate 322 rotates and drives the sealing plug 321 to be pulled out from the inside of the dry powder storage bottle 32.

[0045] After the outlet of the dry powder storage bottle 32 is opened, a large amount of dry powder will fall from the inside of the dry powder storage bottle 32 and fall onto the flames, thereby extinguishing the fire. This method is to deal with a fire that has already started, thereby avoiding causing greater losses.

[0046] After the dry powder is used, in order to ensure normal subsequent use, the protective cover plate 8 will be removed, and dry powder will be added to the inside of the dry powder storage bottle 32 through the feeding pipe 5 to replenish the dry powder in time for subsequent continued use.

[0047] When the electronic components inside the box 1 are working normally, a large amount of heat will be generated. If the heat is not dissipated in time, it will not only affect the use of the electronic components, but also easily cause danger. Therefore, in order to facilitate the heat dissipation inside the box 1, when the heat inside the box 1 continues to rise, the mercury will expand and continue to move upward inside the transparent tube 15. As the temperature inside the box 1 continues to rise, the expansion effect on the mercury becomes more obvious, which will cause the mercury to push the sliding block 27 and drive the retaining ruler 28 to move upward. The device will set the mass of the sliding block 27 and the retaining ruler 28 to 2g, which is very light, making it convenient for mercury to push the sliding block 27 and move one end of the retaining ruler 28 to the position of the infrared sensor 143. The presence of the retaining ruler 28 is detected by the infrared sensor 143, and the electric telescopic rod 141 and the vacuum pump 22 can be controlled by the PLC controller 25.

[0048] The retraction of the telescopic end of the electric telescopic rod 141 will drive the second connecting plate 20 to move upward, and drive the pushing rod 21 to move upward, and the air outlet hood 142 will be pushed upward by the pushing rod 21. Since the air outlet hood 142 is stably connected to the support rod 19, this will limit the air outlet hood 142 to prevent the air outlet hood 142 from falling. When the air outlet hood 142 is pushed upward, it will be separated from the top of the box body 1, and a gap will be left at this time. The hot air inside the box body 1 will be discharged to the outside through the position of the gap, so as to cool the inside of the box body 1.

[0049] At the same time, when the vacuum pump 22 is working, the vacuum pump 22 will extract the gas inside the box 1 and transport the gas to the inside of the pipe 24. The gas inside the pipe 24 will be passed into the inside of the box 1 again, accelerating the fluidity of the gas inside the box 1 and accelerating the discharge of the gas from the gap position, so as to discharge the hot air inside the box 1 and cool down the inside of the box 1 in time to ensure that the electronic components inside the box 1 can be used normally.

[0050] It should be noted that the smoke sensor 31, the electric telescopic rod 141, the infrared sensor 143, the vacuum fan 22 and the PLC controller 25 are devices or equipment existing in the prior art, or are devices or equipment that can be realized in the prior art. Their power supply, specific composition and principles are clear to those skilled in the art, so they will not be described in detail.
