Abstract
Description
Technical Field
[0001] This invention relates to the field of power equipment technology, and in particular to a modular, assembled power metering box. Background Technology
[0002] A metering box is a collection of metering instruments and auxiliary equipment necessary for measuring electrical energy. It is a device used to measure electrical parameters such as electrical energy, voltage, and current. It is commonly used in power systems for electricity metering, load control, and electricity monitoring. The electricity metering box contains various devices such as electricity metering devices, electricity collectors, and circuit protectors. The electricity metering box has become an indispensable part of the power system. In order to meet electricity demand, modular assembled metering boxes have gradually emerged, which have functions such as being detachable, combinable, and expandable.
[0003] Existing patent CN118425586A discloses a modular, assembled energy metering box. A fixed base is welded to the top of the chassis, and several connecting seats are evenly spaced on the top of the fixed base. A hollow back plate is snapped onto one side of the bottom of each connecting seat, and hollow side plates are snapped onto both sides of the hollow back plate. A grid frame is snapped onto the inner side of each hollow side plate. A locking slot is provided at one corner of the top of both the fixed base and the connecting seats. This invention improves the compatibility and adaptability of locking pressure with the size of the metering box, enhances the assembly stability of each module, effectively utilizes elastic contraction characteristics to offset mechanical wear deviations, fully leverages the dynamism of the main function, and allows for adaptive changes in the capacity of the metering box according to actual load requirements. This effectively broadens the effective application range of the metering box, making its use more flexible and efficient, while indirectly improving the effective utilization rate of the metering box and enriching the functionality of modular assembly.
[0004] The above structure enables the metering box to function as a multi-functional device. However, due to its simple heat dissipation structure, the metering box cannot automatically adjust according to changes in internal temperature. In winter, it remains in a low-temperature state for extended periods without insulation, which can easily lead to abnormal operation of internal electrical equipment. In summer, while it may meet the heat dissipation requirements, the high temperature is difficult to control. Once the temperature reaches the ignition point, it can easily cause a fire, which is difficult to extinguish in time. This is not conducive to timely protection of the equipment inside the metering box and reduces its functionality.
[0005] Therefore, how to provide a modular, assembled power metering box is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

The puncture component includes a lifting component with a push-pull component connected to the heat dissipation component. In a first working state (low temperature), the lifting component moves downwards, causing the push-pull component to move downwards and close the heat dissipation component, achieving a heat preservation effect. In a second working state (high temperature), the lifting component moves upwards, causing the push-pull component to move upwards and open the heat dissipation component, achieving a heat dissipation effect. In a third working state (fire), the lifting component continues to move upwards, causing the push-pull component to move upwards and close the heat dissipation component. Simultaneously, under the action of the squeezing component and the ejection component, the puncture component is forced to puncture the storage component, releasing carbon dioxide and achieving a fire extinguishing effect.
[0007] Preferably, the heat dissipation assembly includes a heat dissipation window disposed on the power box, the heat dissipation window having heat dissipation holes, a connecting rod hinged to the power box, a sealing plate hinged to the connecting rod, and a flow hole adapted to the heat dissipation holes on the sealing plate.
[0008] Preferably, the lifting assembly includes a threaded rod connected to the power box by a bearing, a guide rod is provided inside the power box, a lifting plate is threadedly connected to the threaded rod, the threaded rod is threaded through the lifting plate, and the guide rod passes through the lifting plate.
[0009] Preferably, the drive assembly includes a drive motor mounted on the power housing, the output shaft of the drive motor is connected to a driving bevel gear, and a driven bevel gear that meshes with the driving bevel gear is fixedly sleeved on the threaded rod.
[0010] Preferably, the storage component includes a mounting plate disposed within the power box body, on which a plurality of storage glass bottles for storing carbon dioxide are mounted, each storage glass bottle is provided with a gas distribution pipe, and each gas distribution pipe is provided with a conduit, the plurality of gas distribution pipes being connected through the conduit.
[0011] Preferably, the air supply assembly includes an air supply tank disposed on the mounting plate, an air supply pipe disposed on the air supply tank and communicating with the conduit, a control valve disposed on the air supply pipe, the control valve disposed on a connecting pipe passing through the power box and the electrical box, a temperature control valve being installed on the connecting pipe, an annular pipe communicating with the connecting pipe being disposed inside the electrical box, and a plurality of air nozzles being disposed on the annular pipe.
[0012] Preferably, the extrusion assembly includes a limiting block disposed on the lifting plate, an extrusion plate disposed inside the limiting block, an extrusion rod disposed on the extrusion plate that passes through the limiting block, an extrusion spring disposed between the extrusion plate and the limiting block and sleeved on the outer ring of the extrusion rod, and a wedge block disposed on the extrusion rod.
[0013] Preferably, the ejection assembly includes a support frame mounted on the power housing, an ejection rod extending through the support frame, a baffle at the end of the ejection rod, and an ejection spring sleeved on the outer ring of the ejection rod between the support frame and the piercing assembly.
[0014] Preferably, the puncture assembly includes a mounting plate disposed on the ejector rod, the free end of the ejector spring is connected to the mounting plate, the mounting plate is provided with a puncture needle adapted to the storage glass bottle, and the mounting plate is provided with a second wedge block adapted to the first wedge block.
[0015] Preferably, the push-pull assembly includes a connecting frame disposed on the lifting plate, a push-pull rod disposed on the connecting frame, a connecting lug disposed on the sealing plate, and the push-pull rod passing through the connecting lug.
[0016] The beneficial effects of this invention are as follows: In this invention, the electrical equipment inside the power box is assembled to form a power module, and the various components inside the power box form a power module. The power module and the power module are then assembled together, making the power box and the power box a single modular unit. In winter, when temperatures are low, the drive component is activated, causing the lifting component to descend. This downward movement of the lifting component moves the squeezing component away from the puncturing component, and the lifting component also causes the push-pull component to descend, forcing it to pull down the heat dissipation component, thus shutting it off and achieving a heat insulation effect on the power box. In summer, when temperatures are high, the drive component is activated in reverse, causing the lifting component to rise. The movement causes the lifting component to move upward, bringing the squeezing component closer to but not into contact with the puncturing component. The lifting component also causes the pushing-pull component to move upward, forcing it to lift the cooling component, opening it and allowing air convection within the electrical box to dissipate heat. In case of fire, if the internal temperature of the electrical box becomes too high due to summer temperatures or other factors, the drive component will reverse, causing the lifting component to continue moving upward. This forces the lifting component to move the pushing-pull component upward, again lifting the cooling component and closing it, thus cutting off airflow. The gas enters the electrical box, reducing the oxygen content. Simultaneously, because the compression component is close to the puncture component, as the lifting component continues to move upward, it forces the compression component to move upward, causing the puncture component to move upward as well. The puncture component first moves the ejection component upward; when the ejection component reaches its limit, it stores force, while the compression component continues to move, causing it to separate from the puncture component. The puncture component is then released, forcing the ejection component to propel the puncture component downward, puncturing the storage component. This causes the storage component to rupture, releasing carbon dioxide and achieving a fire extinguishing effect. Due to the high temperature, the carbon dioxide is released into the electrical box through the self-control of the gas supply component. This allows carbon dioxide to be released from multiple directions, achieving a rapid fire extinguishing effect. Simultaneously, the gas supply component periodically replenishes the storage component, and staff regularly replace the gas supply component to ensure sufficient carbon dioxide. In summary, this modular, assembled energy metering box can switch between multiple power states, enabling it to adapt to different environments. It provides insulation at low temperatures and heat dissipation at high temperatures. In the event of a fire, it can extinguish the fire over a wide area and in a timely manner through multi-directional fire suppression, reducing the fire's intensity and facilitating timely protection of the internal and external equipment of the energy metering box, thus improving its functionality and safety.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention. Example 1:
[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, a modular assembled energy metering box of the present invention includes a power box 1, an electrical box 2 connected to the power box 1, a heat dissipation component 3 on the electrical box 2, a lifting component 4 inside the power box 1, a drive component 5 connected to the lifting component 4 inside the power box 1, a carbon dioxide storage component 6 inside the power box 1, a gas supply component 7 connected to the storage component 6 inside the power box 1, a compression component 8 on the lifting component 4, an ejection component 9 inside the power box 1, and a puncture component 10 corresponding to the storage component 6 between the compression component 8 and the ejection component 9. The 4 is equipped with a push-pull assembly 11 connected to the heat dissipation assembly 3. In the first working state, i.e. at low temperature, the lifting assembly 4 moves down, causing the push-pull assembly 11 to move down and close the heat dissipation assembly 3, thus achieving a heat preservation effect. In the second working state, i.e. at high temperature, the lifting assembly 4 moves up, causing the push-pull assembly 11 to move up and open the heat dissipation assembly 3, thus achieving a heat dissipation effect. In the third working state, i.e. in case of fire, the lifting assembly 4 continues to move up, causing the push-pull assembly 11 to move up and close the heat dissipation assembly 3. At the same time, under the action of the squeezing assembly 8 and the ejection assembly 9, the puncture assembly 10 is forced to puncture the storage assembly 6, releasing carbon dioxide and achieving a fire extinguishing effect.
[0021] Working principle: The electrical equipment inside the power box 2 is assembled to form a power module, and the various components inside the power box 1 form a power module. The power modules and power modules are then assembled together, making the power box 1 and power box 2 a single modular unit. In winter when temperatures are low, the drive assembly 5 is activated, causing the lifting assembly 4 to descend. This downward movement of the lifting assembly 4 moves the squeezing assembly 8 away from the puncturing assembly 10, and the lifting assembly 4 also moves the push-pull assembly 11 downward, forcing the push-pull assembly 11 to pull down the heat dissipation assembly 3, thus closing the heat dissipation assembly 3 and achieving a heat preservation effect for the power box 2. In summer when temperatures are high, the drive assembly 5 is activated in reverse, causing the lifting assembly 4 to move downward... The upward movement of component 4 causes the lifting component 4 to move upward, bringing the squeezing component 8 closer to but not in contact with the puncturing component 10. The lifting component 4 also causes the push-pull component 11 to move upward, forcing it to lift the heat dissipation component 3, opening it and allowing air convection between the power box 2 and the component itself, thus achieving heat dissipation. In case of fire, if the internal temperature of the power box 2 becomes too high due to summer heat or other factors, the drive component 5 will continue to reverse and move upward, forcing the lifting component 4 to move the push-pull component 11 upward again, forcing it to lift the heat dissipation component 3 again, closing it once more. The system closes, cutting off airflow into the electrical box 2 and reducing oxygen levels. Simultaneously, because the compression component 8 is close to the puncture component 10, as the lifting component 4 continues to move upward, it forces the compression component 8 to move upward, causing the puncture component 10 to move upward as well. The puncture component 10 first moves the ejection component 9 upward. When the ejection component 9 reaches its limit, it stores force, and the compression component 8 continues to move, causing it to separate from the puncture component 10. The puncture component 10 is then released, forcing the ejection component 9 to eject and drive the puncture component 10 downward, puncturing the storage component 6. This causes the storage component 6 to rupture and release carbon dioxide, achieving a fire extinguishing effect. Due to the high temperature, the gas supply component 7 controls the process to... Carbon dioxide is released into the electrical box 2 from multiple directions, achieving a rapid fire extinguishing effect. Simultaneously, the gas supply component 7 periodically replenishes the storage component 6, and staff regularly replace the gas supply component 7 to ensure sufficient carbon dioxide. In summary, this modular, assembled electrical energy metering box can switch between multiple power states, allowing it to adapt to different environments. It provides insulation at low temperatures and heat dissipation at high temperatures. In the event of a fire, it can extinguish the fire over a wide area and promptly through multi-directional fire suppression, reducing the fire's intensity and facilitating timely protection of the internal and external equipment of the electrical energy metering box, thus improving its functionality and safety. Example 2:
[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a modular assembled power metering box of the present invention includes a heat dissipation component 3 comprising a heat dissipation window 301 disposed on the power box body 2, a heat dissipation hole 302 provided on the heat dissipation window 301, a connecting rod 303 hinged to the power box body 2, a sealing plate 304 hinged to the connecting rod 303, and a flow hole 305 provided on the sealing plate 304 that is adapted to the heat dissipation hole 302.
[0023] like Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, a modular assembled power metering box of the present invention includes a lifting assembly 4 comprising a threaded rod 401 connected to a power box 1 by a bearing, a guide rod 402 disposed inside the power box 1, a lifting plate 403 threadedly connected to the threaded rod 401, the threaded rod 401 threadedly penetrating the lifting plate 403, and the guide rod 402 penetrating the lifting plate 403.
[0024] like Figure 5 , Figure 6 and Figure 7 As shown, a modular assembled electricity metering box of the present invention includes a drive assembly 5 comprising a drive motor 501 mounted on a power box 1, an output shaft of the drive motor 501 connected to a drive bevel gear 502, and a driven bevel gear 503 meshing with the drive bevel gear 502 fixedly sleeved on a threaded rod 401.
[0025] like Figure 2 , Figure 3 , Figure 5 and Figure 8 As shown, a modular assembled power metering box of the present invention includes a storage component 6 comprising an installation plate 601 disposed within a power box 1, a plurality of storage glass bottles 602 for storing carbon dioxide mounted on the installation plate 601, a gas distribution pipe 603 disposed on the storage glass bottle 602, a conduit 604 disposed on the gas distribution pipe 603, and the plurality of gas distribution pipes 603 being connected through the conduit 604.
[0026] like Figure 5 and Figure 8 As shown, a modular assembled power metering box of the present invention includes a gas supply assembly 7 comprising a gas supply tank 701 mounted on a mounting plate 601, a gas supply pipe 702 connected to a conduit 604 on the gas supply tank 701, a control valve 703 on the gas supply pipe 702, a connecting pipe 704 passing through the power box 1 and the electrical box 2 on the control valve 703, a temperature control valve 705 installed on the connecting pipe 704, and an annular pipe 706 connected to the connecting pipe 704 inside the electrical box 2, with multiple air nozzles 707 on the annular pipe 706.
[0027] like Figure 9and Figure 10 As shown, a modular assembled electricity metering box of the present invention includes a compression assembly 8 comprising a limiting block 801 disposed on a lifting plate 403, a compression plate 802 disposed inside the limiting block 801, the compression plate 802 being slidably disposed inside the limiting block 801, a compression rod 803 disposed on the compression plate 802 penetrating the limiting block 801, a compression spring 804 sleeved on the outer ring of the compression rod 803 disposed between the compression plate 802 and the limiting block 801, and a wedge block 805 disposed on the compression rod 803.
[0028] like Figure 5 , Figure 6 and Figure 9 As shown, a modular assembled power metering box of the present invention includes an ejection assembly 9 comprising a support frame 901 mounted on a power box 1, an ejection rod 902 extending through the support frame 901, a baffle 903 at the end of the ejection rod 902, and an ejection spring 904 sleeved on the outer ring of the ejection rod 902 between the support frame 901 and the puncture assembly 10.
[0029] like Figure 6 and Figure 9 As shown, a modular assembled power metering box of the present invention includes a puncture assembly 10 comprising a mounting plate 1001 disposed on a catapult rod 902, the free end of a catapult spring 904 being connected to the mounting plate 1001, a puncture needle 1002 adapted to a storage glass bottle 602 being disposed on the mounting plate 1001, and a wedge block 1003 adapted to a wedge block 805 being disposed on the mounting plate 1001.
[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, a modular assembled electricity metering box of the present invention includes a push-pull assembly 11 comprising a connecting frame 1101 disposed on a lifting plate 403, a push-pull rod 1102 disposed on the connecting frame 1101, and a connecting ear 1103 disposed on a sealing plate 304. The push-pull rod 1102 and the connecting ear 1103 slide relative to each other, and the push-pull rod 1102 passes through the connecting ear 1103.
[0031] Working principle: The electrical equipment inside the power box 2 is assembled to form a power module, and the various components inside the power box 1 form a power module. Then, the power module and the power module are assembled together, making the power box 1 and the power box 2 a single modular unit. In low temperatures during winter, the drive motor 501 is started. The output shaft of the drive motor 501 rotates, driving the active bevel gear 502 to rotate. The active bevel gear 502 rotates, driving the driven bevel gear 503 to rotate. The driven bevel gear 503 rotates, driving the threaded rod 401 to rotate. Under the guidance of the guide rod 402, the threaded rod 401 rotates, causing the lifting plate 403 to move downwards. The lifting plate 403 drives the limit block 801, the pressing plate 802, and the pressing... Rod 803 and wedge block 805 move downwards, causing wedge block 805 to move away from wedge block 1003, meaning wedge block 1003 does not move. Lifting plate 403 moves downwards, causing connecting frame 1101 to move downwards. Connecting frame 1101 moves downwards, causing push-pull rod 1102 to move downwards, causing push-pull rod 1102 to move connecting ear 1103 downwards. Since sealing plate 304 is hinged to connecting rod 303, sealing plate 304 rotates downwards and inwards around connecting rod 303, causing sealing plate 304 to fit against heat dissipation window 301. At this time, heat dissipation hole 302 and flow hole 305 are misaligned, and air will not flow, so heat dissipation window 301 is in a closed state, achieving the heat preservation effect of power box 2. During periods of high summer temperatures, the drive motor 501 is reverse-started. The output shaft of the drive motor 501 rotates, causing the driving bevel gear 502 to rotate in the opposite direction. The rotation of the driving bevel gear 502 causes the driven bevel gear 503 to rotate in the opposite direction. The rotation of the driven bevel gear 503 causes the threaded rod 401 to rotate in the opposite direction. Guided by the guide rod 402, the rotation of the threaded rod 401 causes the lifting plate 403 to move upward. The lifting plate 403 causes the limiting block 801, the pressing plate 802, the pressing rod 803, and the wedge block 1 805 to move upward, bringing the wedge block 1 805 close to the wedge block 2 1003, where they are in just-contact. Therefore, wedge block 1003 remains stationary. Lifting plate 403 moves upward, causing connecting frame 1101 to move upward. Connecting frame 1101 moves upward, causing push-pull rod 1102 to move upward, which in turn causes connecting ear 1103 to move upward. Similarly, sealing plate 304 is hinged to connecting rod 303, causing sealing plate 304 to rotate upward and outward around connecting rod 303, thus separating sealing plate 304 from heat dissipation window 301. At this time, heat dissipation hole 302 is aligned with flow hole 305, allowing air convection between power box 2 and the heat dissipation window 301, thus achieving the heat dissipation function of power box 2. Due to high temperatures in summer or other factors, the internal temperature of the electrical box 2 may become excessively high, increasing the risk of fire. In the event of a fire, the drive motor 501 will continue to start in reverse. Under the action of the driving bevel gear 502 and the driven bevel gear 503, the lifting plate 403 will move upward, causing the connecting frame 1101 to continue moving upward. The upward movement of the connecting frame 1101 will cause the push-pull rod 1102 to continue moving upward, which in turn will cause the connecting ear 1103 to continue moving upward. Similarly, the sealing plate 304 will be hinged to the connecting rod 303, causing the sealing plate 304 to rotate upward and inward around the connecting rod 303. The sealing plate 304 and the heat dissipation window 301 are re-attached. At this time, the heat dissipation hole 302 and the flow hole 305 are misaligned again, and air flow is blocked again, causing the heat dissipation window 301 to close again, thereby cutting off air from entering the power box 2 and reducing the oxygen content. At the same time, the lifting plate 403 continues to move upward, driving the limit block 801, the pressing plate 802, the pressing rod 803 and the wedge block 1 805 upward. Since the wedge block 1 805 and the wedge block 2 1003 are already in contact, when the wedge block 1 805 continues to move upward, it will drive the wedge block 2 1003 upward, and the wedge... Block 2 1003 moves the mounting plate 1001 and the piercing needle 1002 upwards. The mounting plate 1001 moves the ejector rod 902 upwards, and the ejector spring 904 is compressed and stores energy. When the ejector rod 902 reaches its limit position, the ejector spring 904 completes energy storage. When the lifting plate 403 continues to move upwards, it causes the wedge block 1 805 to continue moving upwards, while the position of wedge block 2 1003 remains unchanged. At this time, wedge block 1 805 is subjected to compression, causing it to retract. The compression spring 804 is compressed until wedge block 1 805 and wedge block 2 1003 are in relative position. When the device is moved to the separation position, wedge block 1003 is released, as are piercing needle 1002 and mounting plate 1001. Due to the energy storage effect of ejection spring 904, ejection rod 902 moves rapidly downward. Ejection rod 902 drives mounting plate 1001 and piercing needle 1002 to move rapidly downward. Due to inertia, piercing needle 1002 pierces storage glass bottle 602. Due to the elastic force of ejection spring 904, storage glass bottle 602 is pierced instantly, thereby releasing carbon dioxide inside storage glass bottle 602 and achieving fire extinguishing effect. Due to the high temperature, the temperature control valve 705 opens, allowing carbon dioxide in the gas supply tank 701 to be introduced into the nozzle 707 through the gas supply pipe 702, connecting pipe 704, and annular pipe 706. The nozzle 707 then releases the carbon dioxide gas into different areas within the electrical box 2, allowing the carbon dioxide to be released from multiple directions for rapid fire extinguishing. The control valve 703 also allows the carbon dioxide in the gas supply tank 701 to be introduced into the storage glass bottle 602 through the conduit 604 and distribution pipe 603, achieving a filling effect. Staff regularly fill the storage glass bottle 602. When the gas in the gas supply tank 701 is insufficient, the tank is replaced to ensure a sufficient supply of carbon dioxide and prevent insufficient carbon dioxide levels during a fire.
[0032] This solution enables the switching of multiple power states, allowing the electricity metering box to adapt to different environments. On the one hand, it provides insulation at low temperatures and heat dissipation at high temperatures. On the other hand, in the event of a fire, it can extinguish the fire in a wide area and in a timely manner through multi-directional fire suppression, reducing the fire's spread and facilitating the timely protection of the internal and external equipment of the electricity metering box, thus improving the functionality and safety of the electricity metering box. This electricity metering box is particularly suitable for areas with large temperature differences and relatively dry conditions.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
