Description

Technical Field

[0001] The present invention relates to the technical field of power equipment protection, and particularly to an electric meter box with high protection performance. Background Art

[0002] In the power system, distribution boards, substations, and switchgear for power supply or distribution are key equipment to ensure the safe and efficient transmission and distribution of electric energy. Among them, the electric meter box, as a basic component of the distribution system, not only undertakes the installation and protection tasks of electric meters, but also is directly related to the overall operation safety and reliability of the power system.

[0003] For the existing electric meter boxes, although certain protection measures have been taken in terms of structure, such as using a metal shell to resist physical impacts and dust, their protection capabilities still need to be improved when facing more severe environmental challenges, especially the fire risk. Most electric meter boxes only have basic electric meter installation and protection functions and lack special designs for extreme situations such as fires. For example, when a fire is caused by an internal fault or external factors in the electric meter, the existing electric meter boxes cannot respond autonomously and effectively control the fire, resulting in the rapid spread of the fire to the entire interior of the electric meter box and even affecting adjacent electrical equipment, causing serious property losses and safety hazards.

[0004] Therefore, with the increasing requirements of the power system for safety and reliability, there is an urgent need for an electric meter box that is more advanced in structure and more comprehensive in protection performance, especially an electric meter box that can provide effective protection against extreme situations such as fires. Such an electric meter box not only needs to meet basic requirements such as conventional dust and water protection, but also should have special functions such as fire warning, initial fire extinguishing, and fire isolation to ensure that it can respond quickly in case of a fire, effectively control the fire, and protect the overall safety and stability of the power system. Summary of the Invention

[0005] In order to overcome the deficiencies in fire protection and the lack of an emergency handling mechanism, the present invention provides an electric meter box with high protection performance and emergency self - response.

[0009] Further, the fire extinguishing assembly includes a gas storage tank, a telescopic valve, a second elastic member, a rectifying and diverting pipe rack, and a gas discharging member. A plurality of gas storage tanks are clamped on the connecting plate. The rectifying and diverting pipe rack is connected to the top inside the box body. A plurality of openings are provided at the top and bottom of the rectifying and diverting pipe rack. The openings at the bottom are communicated with the delivery pipe. The gas discharging member is arranged inside the openings at the top. The telescopic valve is arranged inside the gas storage tank. The second elastic member is sleeved on the telescopic valve. One end of the second elastic member is connected to the gas storage tank, and the other end is connected to the telescopic valve. The telescopic valve is in extrusion fit with the gas discharging member. The gas storage tank is threadedly connected to the rectifying and diverting pipe rack.

[0010] Further, the control assembly includes a servo motor, a rotating shaft, a disc, a baffle, and a sensor. Sensors are installed at the top inside the box body and at the bottom of the cable pipe. The servo motor is installed at the end of the rectifying and diverting pipe rack. The rotating shaft is rotatably connected inside the rectifying and diverting pipe rack. The rotating shaft is connected to the output shaft of the servo motor. A plurality of discs are connected to the rotating shaft. A baffle is connected between every two discs, and the angle of each baffle around the disc is different. The baffle is in sealing fit with the opening at the top of the rectifying and diverting pipe rack. The sensor is wired to the servo motor through the controller inside the meter box.

[0011] Furthermore, the separation component includes a guide sleeve, a follower frame, a wiring frame, a push plate, an inclined groove, a first wiring piece, a third elastic member, a second wiring piece, a lower terminal and an upper terminal. The guide sleeve is connected to the outside of the protection frame. The follower frame is slidably connected inside the guide sleeve.

[0013] Furthermore, the melting point of the rope is higher than the highest temperature at which the electricity meter normally operates and lower than the temperature of an open flame.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. Through the rope and the first elastic member, when the rope melts due to high temperature and the first elastic member rebounds, it can quickly make an autonomous response to the fire. And through the cooperation among the connecting rod, the rack block, the gear rod and the sealing circular plate, when a fire occurs, the resilience of the first elastic member pushes the connecting rod and the rack block to move, thereby driving the gear rod to rotate, and the sealing circular plate rotates accordingly to open the gas passage, so that the fire extinguishing gas can be quickly released into the electricity meter box to complete the emergency response and achieve the purpose of fire protection.

[0016] 2. Through the sensor, the rotating shaft and the baffle, after the sensor detects a fire, it sends an instruction to the servo motor. The servo motor rotates by a corresponding angle according to the size of the fire to adjust the position of the baffle, thereby controlling different numbers of gas storage tanks to release gas simultaneously, ensuring that the fire extinguishing effect matches the size of the fire, improving the fire extinguishing efficiency and optimizing the use of resources.

[0017] 3. Through the follower frame and the push plate with an inclined groove, the movement of the follower frame drives the push plate to squeeze the inclined groove, so that the first wiring piece and the second wiring piece are separated from contact, quickly cutting off the connection between the electricity meter and the cable during the fire extinguishing process, effectively preventing the fire from spreading to other areas through the circuit and improving the safety of the electricity meter box.

Detailed implementation manners

[0030] The present invention will be specifically described below with reference to the accompanying drawings.

[0031] Embodiment: A meter box with high protection performance, as Figures 1 - 11 shown, includes a box body 1, a partition 11, a cable pipe 12 and a cover plate 13. The box body 1 is divided into multiple areas. A cover plate 13 is rotatably connected to the outside of each area of the box body 1. The cover plate 13 can completely seal the box body 1. Multiple partitions 11 are arranged inside the box body 1. The partitions 11 can block the components at the rear side, so that it will not be messy visually and optimize the overall aesthetics. A cable pipe 12 for guiding cables is arranged inside the box body 1. The cable pipe 12 further divides each area inside the box body 1, making the electric meters divided into multiple layers, which is convenient for management and installation. It also includes a protection mechanism 2 and a separation component 3. A protection component is arranged inside the box body 1. The protection component is used to autonomously respond and perform fire extinguishing work to protect the electric meters installed inside the box body 1. A separation component 3 is arranged inside the box body 1. The separation component 3 responds following the protection component and is used to disconnect the connection between the electric meter and the cable.

[0032] As Figures 2 - 8 shown, the protection mechanism 2 includes a protection frame 21, a hook 22, a trigger component 23, a surrounding pipe 24, air outlet holes 241, a delivery pipe 25, a connecting plate 26, a fire extinguishing component 27 and a control component 28. Multiple protection frames 21 are arranged inside the box body 1. An electric meter is installed in each protection frame 21. The front side of the protection frame 21 is flush with the front side of the partition 11, optimizing the overall aesthetics. At the same time, the partition 11 can be marked to distinguish the electric meters. The front end of the inner circle of the protection frame 21 is connected with a hook 22, and the hook 22 surrounds a whole circle. The surrounding pipe 24 is wound around the outside of the protection frame 21. The protection frame 21 is provided with multiple air outlet holes 241. The surrounding pipe 24 is communicated with the air outlet holes 241. The delivery pipe 25 covers the inside of the box body 1. The delivery pipe 25 is communicated with the surrounding pipes 24 on each protection frame 21. A trigger component 23 is arranged at the communication part of the delivery pipe 25 and the surrounding pipe 24. The trigger component 23 is used to automatically respond to the fire. A connecting plate 26 is connected to the top of the box body 1. A fire extinguishing component 27 for providing fire extinguishing raw materials is arranged inside the connecting plate 26. A control component 28 for adjusting the fire extinguishing ability according to the fire situation is arranged inside the fire extinguishing component 27.

[0033] As Figure 4 and Figure 5As shown in the figure, the triggering component 23 includes a rope 231, a connecting rod 232, a first elastic member 233, a rack block 234, a gear rod 235 and a sealing circular plate 236. A connecting rod 232 is slidably connected to the top of the protective frame 21. A hook 22 is connected to the bottom of the connecting rod 232. The rope 231 passes through all the hooks 22 within a single protective frame 21. The melting point of the rope 231 is higher than the highest temperature at which the electric meter operates normally and lower than the temperature of an open flame. Notches are provided on the front sides of the hooks 22 to facilitate the rope 231 being sleeved on the hooks 22. A first elastic member 233 is sleeved on the connecting rod 232. One end of the first elastic member 233 is fixedly connected to the connecting rod 232, and the other end is fixedly connected to the protective frame 21. A rack block 234 is fixedly connected to the rear side of the top of the connecting rod 232. A sealing circular plate 236 is rotatably connected to the connection between the conveying pipe 25 and the surrounding pipe 24. The rotating shaft of the sealing circular plate 236 passes through the conveying pipe 25 and is connected to a gear rod 235. The gear rod 235 meshes with the rack block 234, and the number of teeth of the rack block 234 is equal to one-fourth of the number of teeth of the gear rod 235. The gear rod 235 rotates 90 degrees each time.

[0034] As Figures 6 - 8 shown in the figure, the fire extinguishing component 27 includes a gas storage tank 271, a telescopic valve 272, a second elastic member 273, a rectifying and shunting pipe rack 274 and a gas discharging member 275. A number of gas storage tanks 271 are snap-connected to the connecting plate 26. A rectifying and shunting pipe rack 274 is connected to the top inside the box body 1. A plurality of openings are provided at both the top and the bottom of the rectifying and shunting pipe rack 274. The openings at the bottom are communicated with the conveying pipe 25. A gas discharging member 275 is arranged in the openings at the top. A telescopic valve 272 is arranged in the gas storage tank 271. A second elastic member 273 is sleeved on the telescopic valve 272. One end of the second elastic member 273 is fixedly connected to the gas storage tank 271, and the other end is fixedly connected to the telescopic valve 272. The telescopic valve 272 is in extrusion fit with the gas discharging member 275. The gas storage tank 271 is threadedly connected to the rectifying and shunting pipe rack 274 to ensure good airtightness.

[0035] As Figure 7 and Figure 8As shown, the control component 28 includes a servo motor 281, a rotating shaft 282, a disc 283, a baffle 284, and a sensor 285. Sensors 285 are installed at the top inside the box body 1 and at the bottom of the cable pipe 12. A sensor 285 is correspondingly arranged above each protective frame 21. A servo motor 281 is installed at the end of the rectifying and shunting pipe rack 274. A rotating shaft 282 is rotatably connected inside the rectifying and shunting pipe rack 274. The rotating shaft 282 is connected to the output shaft of the servo motor 281. A number of discs 283 are connected to the rotating shaft 282. The number of discs 283 is twice the number of gas storage tanks 271. Two discs 283 form a group. A baffle 284 is connected between every two discs 283. And the angle of each baffle 284 around the disc 283 is different. When all the discs 283 rotate by a certain angle, and the rotation angle is greater than the surrounding angle of the baffle 284, the baffle 284 will disengage from the opening of the rectifying and shunting pipe rack 274, and the gas in the gas storage tank 271 can flow into the rectifying and shunting pipe rack 274. Otherwise, the baffle 284 is in sealing cooperation with the top opening of the rectifying and shunting pipe rack 274 to block the gas from passing through. The sensor 285 is wired to the servo motor 281 through a controller in the meter box.

[0036] As Figure 9 and Figure 10 As shown, the separation component 3 includes a guide sleeve 31, a follower frame 32, a wiring frame 33, a push plate 34, an inclined slot 341, a first wiring piece 35, a third elastic member 36, a second wiring piece 37, a lower terminal 38, and an upper terminal 39. A guide sleeve 31 is connected to the outside of the protective frame 21. A follower frame 32 is slidably connected inside the guide sleeve 31. The top of the follower frame 32 is fixedly connected to the connecting rod 232. The front end of the partition 11 is connected to a wiring frame 33. A first wiring piece 35 is slidably connected inside the wiring frame 33. Both ends of the first wiring piece 35 are connected to a push plate 34. The push plate 34 is provided with an inclined slot 341. The bottom of the follower frame 32 passes through the two push plates 34 and is slidably connected inside the inclined slot 341. A third elastic member 36 is arranged between the first wiring piece 35 and the wiring frame 33. A second wiring piece 37 is connected inside the wiring frame 33. The second wiring piece 37 contacts the first wiring piece 35. A lower terminal 38 is arranged at the bottom of the wiring frame 33. The lower terminal 38 is connected to the cable inside the cable pipe 12. An upper terminal 39 is arranged at the top of the wiring frame 33. The upper terminal 39 is connected to the meter inside the protective frame 21 through a cable. The first wiring piece 35 contacts the lower terminal 38, and the second wiring piece 37 contacts the upper terminal 39.

[0037] In the normal state, each component inside the electricity meter box is in a preset position. The first elastic member 233 remains in a compressed state. The rope 231 passes through the hook 22 to ensure the stable immobility of the connecting rod 232 and the rack block 234. At this time, the sealing circular plate 236 tightly seals the connection between the conveying pipe 25 and the surrounding pipe 24 to prevent gas leakage. Meanwhile, the gas storage tank 271 is installed on the top of the rectifying and shunting pipe rack 274. The telescopic valve 272 inside the gas storage tank 271 remains open under the action of the air release member 275. The air release member 275 pushes up the telescopic valve 272, and the second elastic member 273 is in a compressed state. The servo motor 281 is in a standby state. At this time, the position of the baffle 284 can block all the openings at the top of the rectifying and shunting pipe rack 274. The first connection piece 35 and the second connection piece 37 inside the connection frame 33 are respectively in contact with the lower connection terminal 38 and the upper connection terminal 39. The lower connection terminal 38 is connected to the cable inside the cable pipe 12, and the upper connection terminal 39 is connected to the electricity meter. The first connection piece 35 and the second connection piece 37 are in contact to ensure the normal operation of the electricity meter. The third elastic member 36 is in a stretched state;

[0038] When a fire breaks out inside the electricity meter box, the high temperature first melts the rope 231. Since the melting point of the rope 231 is higher than the highest temperature at which the electricity meter operates normally but lower than the temperature of an open flame, it is ensured that a response is made when the temperature reaches the threshold value that may cause a fire. After the rope 231 breaks, the first elastic member 233 quickly rebounds, pushing the connecting rod 232 and the rack block 234 to move upward. The meshing relationship between the rack block 234 and the gear rod 235 causes the gear rod 235 to rotate, which in turn drives the sealing circular plate 236 to rotate, opening the connection channel between the conveying pipe 25 and the surrounding pipe 24. At this time, the fire extinguishing gas, mainly carbon dioxide, is quickly released into the interior of the electricity meter box through the conveying pipe 25, the surrounding pipe 24, and the air outlet holes 241 to start the fire extinguishing operation;

[0039] Meanwhile, the sensor 285 inside the electricity meter box detects the fire signal and activates the servo motor 281 through the controller. The servo motor 281 rotates a certain angle according to the received signal, driving the rotating shaft 282 and the disc 283 to rotate. Since the widths of the baffles 284 connected between every two discs 283 are different, the rotated baffles 284 will open different numbers of openings at the top of the rectifying and shunting pipe rack 274. These openings correspond to the telescopic valves 272 of the gas storage tanks 271, enabling a certain number of gas storage tanks 271 to release gas for fire extinguishing simultaneously. According to the size of the fire detected by the sensor 285, the rotation angle of the servo motor 281 is adjusted, thereby automatically adjusting the fire extinguishing ability and improving the fire extinguishing efficiency;

[0040] During the fire extinguishing process, the connecting rod 232 drives the follower frame 32 to slide upward within the guide sleeve 31. The bottom of the follower frame 32 passes through the two push plates 34 and slides along the inclined groove 341. As the follower frame 32 moves, the inclination angle of the inclined groove 341 causes the push plates 34 to be squeezed and move forward. At the same time, the third elastic member 36 rebounds, causing the first connection piece 35 to separate from the second connection piece 37, thereby cutting off the connection between the electricity meter and the cable. This step effectively prevents the fire from spreading to other areas through the circuit, further improving the safety of the electricity meter box;

[0041] After the rescue personnel arrive at the scene, remove the used gas storage tank 271, replace the damaged electricity meter, reconnect the cable, manually press down the connecting rod 232 to compress the first elastic member 233, put the rope 231 on the hook 22. During the movement of the connecting rod 232, it drives the follower frame 32 to move, stretching the third elastic member 36, and the first connection piece 35 and the second connection piece 37 come into contact to reset the rotation angle of the servo motor 281;

[0042] It should be noted that the first connection piece 35 and the second connection piece 37 are structures with four metal conductive sheets, and the four metal conductive sheets are spaced apart. When the first connection piece 35 and the second connection piece 37 are in contact, the first connection piece 35 is in contact with the lower terminal 38, and the second connection piece 37 is in contact with the upper terminal 39. The current is conducted through the independent contact of the metal conductive sheets.

[0043] As Figure 11 shown, it also includes a mounting plate 4 and a sliding frame 41. The sliding frame 41 is slidably connected within the protective frame 21, and the mounting plate 4 for installing the electricity meter is connected to the sliding frame 41.

[0044] The design of the mounting plate 4 and the sliding frame 41 inside the electricity meter box facilitates the installation and maintenance of the electricity meter. When installing or replacing the electricity meter, the sliding frame 41 can be pulled out to pull the mounting plate 4 and the electricity meter to a convenient position for operation. This design not only improves work efficiency but also ensures the stability and safety of the electricity meter during installation.

[0045] Once a fire breaks out inside the electricity meter box, the high temperature quickly melts the rope 231, triggering the response mechanism. The first elastic member 233 releases energy, pushing the connecting rod 232 and the rack block 234 to move. Then, through the gear rod 235, it drives the sealing circular plate 236 to rotate, opening the connection channel between the delivery pipe 25 and the surrounding pipe 24. At this time, the gas in the fire extinguishing assembly 27 quickly diffuses into the interior of the electricity meter box through the delivery pipe 25, the surrounding pipe 24, and the air outlet 241 to perform the fire extinguishing operation. Meanwhile, after detecting the fire, the sensor 285 emits a signal, and the controller immediately sends an instruction to the servo motor 281. The servo motor 281 rotates by a corresponding angle according to the number of signals fed back by the sensor 285. Through the combination of the disc 283 and the baffle 284, it automatically adjusts the number of openings at the top of the opened rectifying and shunting pipe rack 274, enabling a certain number of gas storage tanks 271 to release gas simultaneously, realizing the automatic adjustment of the fire extinguishing capacity. During the fire extinguishing process, the movement of the connecting rod 232 also drives the follower frame 32 to move upward. The inclined groove 341 at the bottom of the follower frame 32 is designed such that the push plate 34 is squeezed and moves forward, causing the first wiring piece 35 to be disengaged from the second wiring piece 37, thus quickly cutting off the connection between the electricity meter and the cable and preventing the fire from spreading through the circuit.

[0046] As described above, it is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention.
