Meet the requirements of environmental protection and energy saving: in the overall design, attention is paid to the selection of environmentally friendly materials and the application of energy-saving technology, so that the electric energy metering box can realize its functions while minimizing the impact on the environment and energy consumption. In summary, the environmentally friendly and energy-saving electric energy metering box described in the present application has significant innovations and advantages in fire extinguishing, and is expected to provide a safer and more reliable solution for the electric energy metering field in practical applications.

[0057] Further, the head valve body 5 is arranged at the nozzle 402, has a rotating valve rod 501 and has a first pin hole 502 on one side of the rotating valve rod 501; the pressure handle 6 is arranged on the rotating valve rod 501, and the pressure handle 6 has a second pin hole 601; the first elastic member 7 is connected to the fire extinguisher 4 at one end and connected to the pressure handle 6 at the other end, providing a force for the pressure handle 6 to rotate to open the head valve body 5; the opening pin 8 is slidably arranged in the first pin hole 502 and extends into the second pin hole 601.

[0058] In this embodiment, the electric energy metering box further comprises a valve body 5, a pressure handle 6, a first elastic member 7 and an opening pin 8. The valve body 5 is arranged at the nozzle 402 of the fire extinguisher 4, with a rotating valve rod 501 and a first pin hole 502; the pressure handle 6 is arranged on the rotating valve rod 501 and has a second pin hole 601; the first elastic member 7 is connected to the fire extinguisher 4 at one end and to the pressure handle 6 at the other end; and the opening pin 8 is slidingly arranged in the first pin hole 502 and extends into the second pin hole 601.

[0059] In this embodiment, the valve body 5 is installed at the nozzle 402 of the fire extinguisher 4 and plays a key role in controlling the discharge of fire extinguishing agent. By cooperating the rotating valve rod 501 with the pressure handle 6, the opening and closing operations of the fire extinguisher 4 are realized. The innovation point is to accurately control the release of fire extinguishing agent, ensuring that the fire extinguishing agent can be quickly and effectively discharged when needed, improving the timeliness and accuracy of fire extinguishing. The pressure handle 6 is arranged on the rotating valve rod 501 and is used to open the fire extinguisher 4 by rotating or pressing, etc., in cooperation with the valve body 5, so that the fire extinguishing agent is discharged. It provides a convenient way to operate the fire extinguisher 4, so that the fire extinguishing device can be quickly started in an emergency. The first elastic member 7 is connected to the fire extinguisher 4 at one end and to the pressure handle 6 at the other end, providing the force for the pressure handle 6 to rotate and open the valve body 5. In the normal state, the pressure handle 6 is kept in the closed position, and when fire extinguishing is needed, the force of the first elastic member 7 pulls the pressure handle 6 to open the valve body 5 for fire extinguishing. Thus, the fire extinguisher 4 is kept in the closed state when not in use, improving the safety. At the same time, when fire extinguishing is needed, the fire extinguisher 4 can be quickly opened with the help of the force of the first elastic member 7, improving the response speed of fire extinguishing.

[0060] In this embodiment, the opening pin 8 is slidingly arranged in the first pin hole 502 and extends into the second pin hole 601, which plays a role in locking the pressure handle 6 to prevent accidental opening of the fire extinguisher 4 due to misoperation. When fire extinguishing is needed, the opening pin 8 is pulled out to release the locking of the pressure handle 6. This increases the safety of the fire extinguisher 4, avoids unnecessary release of fire extinguishing agent due to misoperation, and improves the reliability of the electric energy metering box.

[0061] In this embodiment, the fire extinguishing can be accurately controlled: the cooperation of the valve body 5 and the pressure handle 6 can realize accurate control of the discharge of fire extinguishing agent, ensuring the maximization of fire extinguishing effect. It can quickly respond to fire extinguishing: the setting of the first elastic member 7 enables the fire extinguisher 4 to be quickly opened in an emergency, improving the response speed of fire extinguishing and reducing the loss caused by fire. Safe and reliable: the locking function of the opening pin 8 effectively prevents misoperation, improving the safety and reliability of the electric energy metering box.

[0062] In summary, the newly added components realize accurate control, quick response and safe and reliable operation of the fire extinguisher 4, providing a stronger guarantee for the safe operation of the electric energy metering box.

[0063] Further, a tension spring 9 is also included, one end of which is connected to the opening pin 8 to provide the force for pulling the opening pin 8 out of the second pin hole 601; and a rubber puller 10, one end of which is used to act on the opening pin 8 to provide the force for pulling the opening pin 8 into the second pin hole 601, and the rubber puller 10 is designed to be burnt off to pull the opening pin 8 out of the second pin hole 601.

[0064] In this embodiment, the tension spring 9 and the rubber puller 10 are further introduced. One end of the tension spring 9 is connected to the opening pin 8, which provides the force for pulling the opening pin 8 out of the second pin hole 601. One end of the rubber puller 10 also acts on the opening pin 8, which provides the force for pulling the opening pin 8 into the second pin hole 601, and when a specific condition is encountered, the rubber puller 10 will be burnt off, so that the opening pin 8 is pulled out of the second pin hole 601, thereby achieving the function of quickly extinguishing the fire in the metering box when a fire occurs.

[0065] In this embodiment, the tension spring 9 is always in tension, exerting an outward pulling force on the opening pin 8. When the extinguisher needs to be opened, this pulling force can help the opening pin 8 to be quickly pulled out of the second pin hole 601, thereby releasing the locking of the pressure handle 6, so that the pressure handle 6 opens the valve body 5 under the action of the first elastic member 7, and the extinguisher starts to extinguish the fire. A reliable source of opening force is provided to ensure that the opening pin 8 can respond quickly in an emergency, improving the timeliness of extinguishing the fire.

[0066] In this embodiment, under normal conditions, the rubber puller 10 exerts a pulling force on the opening pin 8 to keep the opening pin 8 in the second pin hole 601, thereby locking the pressure handle 6 to prevent the extinguisher from being accidentally started. When a fire occurs inside the electric energy metering box and the temperature rises to a certain extent, the rubber puller 10 will be burnt off. At this time, the pulling force of the tension spring 9 will play a dominant role in quickly pulling the opening pin 8 out of the second pin hole 601 to start the extinguishing program. On the one hand, the safety of the extinguisher is ensured under normal conditions to avoid accidental operation; on the other hand, the extinguishing device can be automatically triggered when a fire occurs without the need for manual intervention, improving the reliability and timeliness of extinguishing the fire.

[0067] In this embodiment, the automatic fire extinguishing function: through the cooperation of the tension spring 9 and the rubber pull piece 10, the automatic fire extinguishing function of the electric energy metering box in case of fire is realized. When the fire occurs, the rubber pull piece 10 is burned off, the tension spring 9 pulls the opening pin 8 quickly, and the fire extinguisher is started to extinguish the fire, greatly improving the efficiency and timeliness of fire extinguishing. Safe and reliable: under normal circumstances, the rubber pull piece 10 can effectively lock the fire extinguisher, prevent misoperation, and improve the safety of the electric energy metering box. At the same time, the existence of the tension spring 9 also ensures that the fire extinguishing device can be started quickly when needed, improving the reliability of the equipment. Strong adaptability: this design can adapt to different environmental temperatures and fire conditions, with strong adaptability and stability. Whether in high temperature environment or in case of sudden fire, it can effectively play the role of fire extinguishing.

[0068] In summary, the addition of the tension spring 9 and the rubber pull piece 10 further improves the fire extinguishing function of the environmentally friendly and energy-saving electric energy metering box, improves the safety and reliability of the equipment, and has important practical application value.

[0069] Further, it further comprises a first hanging joint 11 and a second hanging joint 12, the first hanging joint 11 and the second hanging joint 12 are respectively arranged at the other end of the tension spring 9 and the rubber pull piece 10,

[0070] A first hanging ring 13 and a second hanging ring 14, the first hanging ring 13 and the second hanging ring 14 are arranged on the fire extinguisher 4 or on the box body 1, the first hanging joint 11 is used for hanging on the first hanging ring 13, and the second hanging joint 12 is used for hanging on the second hanging ring 14.

[0071] In this embodiment, the first hanging joint 11, the second hanging joint 12, the first hanging ring 13 and the second hanging ring 14 are designed. The first hanging joint 11 and the second hanging joint 12 are respectively arranged at the other end of the tension spring 9 and the rubber pull piece 10, the first hanging ring 13 and the second hanging ring 14 are arranged on the fire extinguisher 4 or the box body 1, the first hanging joint 11 is hung on the first hanging ring 13, and the second hanging joint 12 is hung on the second hanging ring 14.

[0072] In this embodiment, the first hanging joint 11 and the second hanging joint 12 are used as the key components for connecting the tension spring 9 and the rubber pull piece 10 with the hanging ring, ensuring that the tension spring and the rubber pull piece can stably play a role. The first hanging joint 11 transmits the tension of the tension spring to the first hanging ring, and the second hanging joint 12 transmits the tension of the rubber pull piece to the second hanging ring. It is convenient to install and disassemble, and it is convenient to operate when maintaining and replacing parts. At the same time, the design of the hanging joint can ensure the firmness of the connection, prevent the situation of falling off in the process of use.

[0073] In this embodiment, the first and second hanging rings 13 and 14 provide hanging positions, allowing the tension spring 9 and the rubber pull 10 to be connected to the fire extinguisher 4 or the box body 1. The first hanging ring 13 receives the tension spring tension force transmitted by the first hanging joint 11, and the second hanging ring 14 receives the rubber pull tension force transmitted by the second hanging joint 12. They can be arranged at different positions according to actual needs, improving the flexibility of the design. The hanging ring has a simple structure and high reliability, and can withstand a certain tension force, ensuring that the effects of the tension spring and the rubber pull can be effectively transmitted to the fire extinguisher.

[0074] In this embodiment, the connection stability is enhanced: through the cooperation of the hanging joint and the hanging ring, the connection between the tension spring 9 and the rubber pull 10 and the fire extinguisher 4 or the box body 1 is more stable and reliable. In the event of a fire, it can ensure that the tension spring and the rubber pull can accurately play a role and start the fire extinguisher to extinguish the fire. Convenient maintenance and replacement: the design of the hanging joint and the hanging ring makes the maintenance and replacement of the components more convenient and efficient. When the tension spring, rubber pull or other components need to be replaced or maintained, you only need to remove the hanging joint from the hanging ring to operate, improving the maintenance efficiency. Improve design flexibility: the position of the hanging ring can be set according to actual conditions, increasing the flexibility of the design. The appropriate position of the hanging ring can be selected according to the installation position of the fire extinguisher, the structure of the box body and other factors, making the design of the entire electric energy metering box more reasonable and efficient.

[0075] In summary, the addition of the first and second hanging joints 11 and 12 and the first and second hanging rings 13 and 14 further improves the structure of the environmentally friendly and energy-saving electric energy metering box and improves its performance and reliability.

[0076] Further, the opening pin 8 has a strip-shaped hole 801 and also includes a plug rod inserted into the strip-shaped hole 801, and the rubber pull 10 is two, one end of each of the two rubber pulls 10 is connected to the two ends of the plug rod, and when one of the rubber pulls 10 is burned off, the plug rod swings in the strip-shaped hole 801 and is pulled by the other rubber pull 10.

[0077] In this embodiment, the structure of the opening pin 8 is designed and a plug rod is added. The opening pin 8 has a strip-shaped hole 801, and the plug rod is inserted into the strip-shaped hole 801. Meanwhile, the rubber pull 10 is two, one end of each of the two rubber pulls 10 is connected to the two ends of the plug rod. When one of the rubber pulls 10 is burned off, the plug rod swings in the strip-shaped hole 801 and is pulled by the other rubber pull 10.

[0078] In this embodiment, the strip-shaped hole 801 of the opening pin 8 provides space for the installation and movement of the plug rod. The design of the strip-shaped hole 801 allows the plug rod to swing to a certain extent, so that when one of the two rubber pulls 10 is burned off, the opening pin 8 can be opened.

[0079] In this embodiment, the plug rod serves as an intermediate component connecting the two rubber pullers 10, and plays a key role in transmitting the pulling force and achieving specific actions in the system. When one rubber puller 10 is burned off, the plug rod swings in the strip-shaped hole 801, allowing the other rubber puller 10 to slide out of the strip-shaped hole 801 following the plug rod, thereby ensuring the activation of the fire extinguishing device, so that the fire extinguishing device can be activated even if one of the two rubber pullers 10 is burned off.

[0080] Further, the opening of the second pin hole 601 is oriented towards the plug rod.

[0081] In this embodiment, when the opening of the second pin hole 601 is oriented towards the plug rod, the opening of the second pin hole 601 is oriented towards the plug rod, which can make the opening of the second pin hole 601 more uniform and direct when subjected to the pulling force of the rubber puller 10 and the plug rod. Such design helps to ensure that the opening of the second pin hole 601 can be stably inserted into the second pin hole 601 in the normal state, thereby improving the stability of the fire extinguishing device in the locked state. At the same time, the accurate orientation can reduce the possibility of misalignment of the opening of the second pin hole 601 and the second pin hole 601 due to external interference or loose parts, further enhancing the reliability of the system.

[0082] In this embodiment, when one of the rubber pullers 10 is burned off during a fire, the plug rod swings in the strip-shaped hole 801 and is pulled by the other rubber puller 10. At this time, since the opening of the second pin hole 601 is oriented towards the plug rod, the opening of the second pin hole 601 can respond more quickly to this change in pulling force and be more easily pulled out of the second pin hole 601. This design can speed up the activation of the fire extinguishing device and improve the timeliness and effectiveness of fire extinguishing.

[0083] Further, the end of the opening of the second pin hole 601 near the second pin hole 601 has a circular clamping groove, and further comprising:

[0084] The positioning bead 16 is arranged in the second pin hole 601, and the head of the positioning bead 16 extends into the circular clamping groove.

[0085] In this embodiment, the structural features of the opening of the second pin hole 601 are designed and the positioning bead 16 is added. The end of the opening of the second pin hole 601 near the second pin hole 601 has a circular clamping groove, and the positioning bead 16 is arranged in the second pin hole 601 and partially extends into the circular clamping groove.

[0086] In this embodiment, the circular groove provides a locking position for the positioning bead 16, enhancing the connection stability between the opening pin 8 and the pressure handle 6. When the opening pin 8 is inserted into the second pin hole 601, the positioning bead 16 is engaged in the circular groove, preventing the opening pin 8 from accidentally coming out and ensuring that the fire extinguisher is in a locked state under normal conditions. This improves the reliability and safety of the connection. The design of the circular groove makes the connection between the opening pin 8 and the pressure handle 6 more secure, reducing the possibility of the opening pin 8 loosening due to external vibration or other factors.

[0087] In this embodiment, the positioning bead 16, located within the second pin hole 601, serves a positioning and locking function. When the opening pin 8 is inserted into the second pin hole 601, the positioning bead 16 partially extends into the circular slot, further fixing the position of the opening pin 8 and preventing it from moving unexpectedly. When it is necessary to pull out the opening pin 8 to activate the fire extinguisher, the positioning bead 16 can disengage from the circular slot under a certain external force, without obstructing the movement of the opening pin 8. This increases the stability and reliability of the system. The design of the positioning bead 16 makes the locking of the opening pin 8 more reliable, and it can also be easily unlocked when the fire extinguisher needs to be activated, improving the system's response speed and safety.

[0088] Furthermore, there are two positioning beads 16, which are located on both sides of the opening pin 8.

[0089] In this embodiment, two positioning beads 16 are located on either side of the opening pin 8, enabling the opening pin 8 to be positioned and fixed from two different directions. This symmetrical layout allows the opening pin 8 to receive a more uniform force after being inserted into the second pin hole 601, thereby improving the stability of the connection. Compared to a single positioning bead, two positioning beads can better resist interference from external forces, reducing the movement or loosening of the opening pin 8 under unexpected circumstances, and ensuring that the fire extinguisher is always in a reliable locked state under normal conditions.

[0090] The arrangement of the two positioning beads 16 makes the insertion and removal of the opening pin 8 smoother and more stable. When inserting the opening pin 8, the positioning beads on both sides can simultaneously engage with the circular slots, guiding the opening pin 8 to accurately insert into the second pin hole 601, reducing operational difficulty and errors. When removing the opening pin 8, the synchronous disengagement of the two positioning beads also makes the operation easier and more reliable.

[0091] Furthermore, it also includes a safety catch 17, one end of which is hinged to the valve body 5 and the other end has a bayonet 1701. After the safety catch 17 is rotated, the end of the insert rod is inserted into the bayonet 1701. There are two safety catches 17, which are symmetrically arranged on both sides of the valve body 5.

[0092] In this embodiment, a safety card 17 is added. One end of the safety card 17 is hingedly arranged on the valve body 5, and the other end has a card hole 1701. After the safety card 17 is turned, the end of the plug rod can be inserted into the card hole 1701, and the safety card 17 is symmetrical on both sides of the valve body 5.

[0093] In this embodiment, the safety card 17 serves as an additional safety mechanism. Before installation, the safety card 17 can be clamped by the card hole 1701 to prevent the opening pin 8 from accidentally falling out, ensuring that the fire extinguisher cannot be accidentally started. When the fire extinguisher is installed, the safety card 17 can be turned open to release the restriction on the plug rod to ensure that the fire extinguisher can extinguish the fire in time. The safety card 17 provides double insurance, even if the positioning bead 16 fails, it can effectively prevent the accidental start of the fire extinguisher. At the same time, the two symmetrical safety cards 17 can fix the plug rod from both sides, improving the stability of the fixed.

[0094] In this embodiment, the card hole 1701 cooperates with the plug rod to achieve clamping and fixing of the plug rod. When the safety card 17 is turned to the appropriate position, the card hole 1701 can tightly clamp the plug rod to prevent it from moving. This ensures the effective fixing of the safety card 17 to the plug rod, improving the safety of the system. The shape and size of the card hole 1701 can be designed according to the specifications of the plug rod to ensure the firmness of the clamping.

[0095] In this embodiment, the safety card 17 provides additional safety protection before the fire extinguisher is installed in the electric energy metering box, reducing the risk of accidental start of the fire extinguisher. The two symmetrical safety cards 17 can fix the plug rod from both sides, improving the stability of the fixed, ensuring that the fire extinguisher can be reliably locked before being installed in the electric energy metering box. After the fire extinguisher is installed in the electric energy metering box, only the safety card 17 needs to be turned open, which is simple and convenient. The added safety card 17 further improves the design of the environmentally friendly and energy-saving electric energy metering box, improving its safety and reliability.

[0096] Further, the partition space 101 includes a metering module space, a switch module space, and a mutual inductor module space.

[0097] In this embodiment, the metering module space is specially used for installing electric energy metering related equipment such as electric energy meter, etc. By separating the metering module, the metering equipment can be better protected, and the influence of other modules on the metering accuracy can be reduced. At the same time, it is also convenient to maintain and manage the metering equipment, and improve the accuracy and reliability of metering.
