With the intelligent development of power systems, modern power metering boxes not only possess basic metering functions but also monitor system status in real time and interact with other power management systems. These devices are designed with various environmental factors in mind, ensuring stable operation under harsh outdoor conditions and improving the efficiency and safety of power facility maintenance. Overall, outdoor power metering boxes, while guaranteeing accurate power metering, are driving the power industry towards a more intelligent and efficient direction.

[0003] A search revealed an existing patent (publication number: CN117578194A) disclosing an outdoor electricity metering box, relating to the technical field of electricity metering boxes. The box includes a body and a cover, the cover being detachably connected to the body. Inside the body are installed a connector body and an electricity meter body. An observation window is installed on the cover. An adjustment assembly is provided inside the box, comprising an adjustment plate and several mounting rods. The mounting rods can slide and be fixed along the length of the adjustment plate. The connector body is detachably connected to the mounting rods. This application, through the adjustment assembly, adjusts the installation height of the connector body, thereby adjusting the installation position of the connector body inside the box. This allows for adjustment of the internal installation layout, reducing the possibility of cable tangling due to unreasonable spatial layout, reducing potential safety hazards, and improving the internal safety performance of the box.

[0004] However, in actual use of the above solutions, if a fire occurs and the equipment cannot respond quickly enough to buy time for subsequent firefighting, it may cause the fire to spread, delay firefighting time, increase the risk of equipment damage, and may also cause power outages or instability in the power system, affecting the power supply of the surrounding area. In addition, the spread of the fire may endanger the safety of staff and people in the surrounding area, and even cause environmental pollution. Therefore, equipment that lacks timely response will not only increase maintenance and replacement costs, but may also have long-term negative impacts on power facilities, the environment and personnel safety.

[0017] Compared with the prior art, the present invention provides an outdoor power metering box, which has the following beneficial effects: 1. The outdoor power metering box of this invention, through the cooperation of a storage component and a delivery component, allows for the rapid discharge of liquid carbon dioxide from the storage component into the main unit when a fire occurs, thereby displacing oxygen and other gases inside and cutting off the oxygen supply to the fire source, thus effectively extinguishing the flames. This design not only protects the equipment from fire damage and reduces downtime, but also avoids equipment pollution and reduces maintenance costs because carbon dioxide extinguishing leaves no residue. Furthermore, the carbon dioxide fire extinguishing system is environmentally friendly, harmless, and non-corrosive to equipment, improving equipment safety and ensuring rapid recovery in the event of a fire, further reducing safety risks. 2. The outdoor energy metering box of this invention utilizes a lateral movement component, a guide component, and a climbing component in coordination to drive the connecting component and the jetting component to move laterally and longitudinally within the main unit housing. This vaporizes the liquid carbon dioxide inside the storage component and discharges it. Due to the heat absorption characteristic of liquid carbon dioxide vaporization, the vaporized carbon dioxide reaches a low temperature, allowing it to be directly sprayed onto areas with higher temperatures for localized cooling. This effectively reduces the risk of overheating, precisely regulates temperature, extends equipment lifespan, and ensures stable operation. Flexible jetting control prevents excessive cooling. Furthermore, the system is environmentally friendly and energy-saving, requiring no additional electricity and reducing energy consumption. Rapid response to temperature changes and immediate cooling help prevent equipment damage or fire, improving equipment safety, especially in extreme outdoor climates. In summary, this temperature control design improves the stability, safety, and long-term performance of the outdoor energy metering box. 3. The outdoor power metering box of this invention can seal the dustproof net through a sealing component, preventing external gases and liquids from entering the main unit box. In the event of a fire, this seals the main unit box, reducing carbon dioxide leakage, improving fire extinguishing efficiency, ensuring carbon dioxide exerts its maximum fire extinguishing effect within the box, protecting the equipment from external pollutants or liquids, ensuring equipment safety, reducing carbon dioxide leakage, lowering the consumption of the fire extinguishing system, and improving its economy and efficiency. Simultaneously, the sealing design enhances the stability of the equipment, avoids the impact of external climate changes on the box, and enables rapid response in the event of a fire, improving emergency handling capabilities and ensuring the safe and efficient operation of the outdoor power metering box in emergency situations.

[0031] Specifically, when this outdoor electricity meter box is in operation: Firstly, during daily use, the temperature of the components inside the main unit 1 is monitored by the temperature sensor on the outside of the lifting frame 52. After the component temperature reaches the predetermined temperature, the first motor 41 drives the synchronous toothed belt 42 to rotate. At the same time, the synchronous toothed belt 42 drives the slide table 43 to move outside the slide rod 45, thereby driving the bottom guide rod 5 to move synchronously through the slide table 43. During the process, the sliding sleeve 46 will be pushed to move on the slide rod 45. Then, the second motor 54 drives the drive gear 55 to rotate. Through the cooperation between the drive gear 55 and the toothed belt 51, the lifting frame 52 can be raised and lowered outside the guide rod 5 using the limit wheel 53, thereby adjusting the height of the lifting frame 52. At the same time, the metering pump 33 extracts liquid carbon dioxide from the gas storage cylinder 3 through the manifold 32, and delivers it into the distribution box 39 through the first delivery pipe 35, the first connecting hose 36, the second delivery pipe 37 and the second connecting hose 38. The low-temperature carbon dioxide gas is then sprayed out through the distribution box 39 to cool down the high-temperature components. In the event of a fire, the electric push rod 21 first moves the sliding plate 22 to the bottom using the support plate 2 as the stress point. At the same time, the sliding plate 22 moves the sealing plate 24 to the bottom using the connecting rod 23 to seal the dustproof net 13, preventing external air from entering the main unit box 1 through the dustproof net 13, thereby sealing the main unit box 1. Then, the solenoid valve at the top of the output end of the metering pump 33 disconnects the metering pump 33 from the first delivery pipe 35, connecting the metering pump 33 to the first exhaust valve 34 and increasing the output power, so that carbon dioxide is directly delivered into the main unit box 1 through the first exhaust valve 34, squeezing out the air inside the main unit box 1 and expelling it through the top exhaust fan, thereby using carbon dioxide to extinguish the fire.
