[0001] This invention belongs to the technical field of electricity metering boxes, and specifically relates to an electricity metering box with high heat dissipation. Background Technology

[0002] Currently, traditional electricity metering boxes mostly use bolts to directly fix the electricity meter to the circuit. This requires power to be disconnected before installation, and the wiring process is easily obstructed by the already installed meters, resulting in low wiring efficiency.

[0003] To address the aforementioned issues, this patent proposes a high-heat-dissipation energy metering box that supports rapid live disassembly and allows for pre-wiring, thereby resolving the technical problems mentioned above. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-heat-dissipation electricity metering box, comprising a box base, a box body connected to the outside of the box base, and a box door hinged to the side of the box body away from the box base. A mounting base located inside the box body is connected to the outside of the box base, and multiple electricity meters are connected to the other end of the mounting base. Each of the multiple electricity meters has mounting ears at its four corners near the mounting base, and a terminal block is provided at the lower end of each of the multiple electricity meters near the mounting base, with two terminals inside the terminal block. A wiring assembly is provided between the electricity meters and the mounting base, and the electricity meters can be quickly disassembled and assembled in the circuit through the wiring assembly, and the heat dissipation and circuit connection path can be controlled according to the disassembly and assembly. The wiring assembly consists of an installation mechanism, an alignment mechanism, and an electrical connection mechanism.

[0006] Preferably, the installation mechanism includes an installation plate, which is provided between the installation base and the electricity meter, and the installation plate is installed outside the installation base. Adjustment grooves are provided at the four corners of the installation plate near the electricity meter.

[0007] Preferably, the adjusting groove is fitted with an adjusting screw extending to the outside and is slidably connected to the adjusting screw, the adjusting screw passing through the mounting lug of the energy meter.

[0008] Preferably, the alignment mechanism includes an alignment seat. The lower end of the terminal block of the power meter is provided with an alignment seat, and two height adjustment electrode sleeves are symmetrically arranged inside the upper end of the alignment seat. The lower side of the two height adjustment electrode sleeves near the mounting base is connected to an electrode plug extending to the outside of the alignment seat, and a height adjustment electrode rod is inserted into the upper end of the two height adjustment electrode sleeves.

[0009] Preferably, the upper end of the height adjustment electrode rod is connected to an electrode base, and the electrode base has an adjustment gap groove at one end near the mounting base. An electrode plate is slidably connected inside the electrode base and the adjustment gap groove, and the upper end of the electrode plate is mounted on the terminal block of the energy meter and connected to the terminal block.

[0010] Preferably, the electrical connection mechanism includes an electrical connection base, and an electrical connection base installed outside the mounting base is provided on the lower side of the terminal block of the power meter. An electrical connection slot is provided on the upper end of the electrical connection base away from the mounting base, and an electrode socket is provided inside the upper end of the electrical connection slot near the mounting base.

[0011] Preferably, the alignment seat is snapped into the electrical connection slot and fits against the electrode socket. The electrode socket has symmetrically arranged electrode insertion sleeves at one end near the alignment seat, and both electrode insertion sleeves have internal telescopic blocks that are slidably connected inside.

[0012] Preferably, the electrode plug is inserted into the two electrode plug sleeves and fits against the inner telescopic block. The inner telescopic block is provided with a telescopic spring at the end away from the electrode plug. The lower end of the electrode plug sleeve is connected to a wire connecting tube that passes through the lower end of the electrical connector. The electrode plug sleeve is provided with a side sliding groove at the end near the other electrode plug sleeve.

[0013] Preferably, a side connecting block connected to the outside of the inner telescopic block is slidably connected inside the side sliding groove, and an electrical connecting block is slidably connected inside the side connecting block at the end away from the inner telescopic block. Multiple bonding springs are provided on the end of the electrical connecting block near the inner telescopic block.

[0014] Preferably, the electrode socket has a circuit direct connection plate located on the front side between the two side slide grooves inside one end near the alignment seat, and the circuit direct connection plate is close to the opening of the two electrode plug sleeves and does not contact the two electrode plug sleeves.

[0015] Compared with the prior art, the present invention provides a high heat dissipation power metering box, which has the following beneficial effects:

[0016] 1. This invention is equipped with an independent heat dissipation component, which can automatically open or close the heat dissipation vents according to the installation status of the electricity meter. When the electricity meter is installed, the heat dissipation vents will automatically open to start precise and individual heat dissipation for the electricity meter; when the electricity meter is removed, the heat dissipation vents will automatically close to avoid wasting airflow and achieve energy saving and consumption reduction.

[0017] 2. This invention adapts to different sizes of electricity meters with the same aspect ratio through the installation mechanism of the wiring assembly. By adjusting the position of the four adjusting screws in the slide groove, meters of different specifications are fixed in the center of the mounting plate, ensuring that they can be smoothly installed in the electricity metering box, thus improving the versatility and flexibility of the equipment.

[0018] 3. The present invention adapts to the wiring terminals of different specifications of energy meters through the alignment mechanism of the wiring assembly. The electrode plates of the alignment mechanism can be adjusted bidirectionally. It can adjust the distance between the two electrode plates according to the spacing between the wiring terminals of the energy meter, and also adjust the overall height according to the spacing between the energy meter and the electrical connection mechanism, thereby achieving a precise connection between the wiring assembly, the energy meter and the electrical connection mechanism.

[0019] 4. This invention enables the maintenance or replacement of the energy meter by plugging and unplugging the electrical connection mechanism and the alignment mechanism, without disconnecting the circuit. When removing the energy meter, as the electrode plug is pulled out of the electrode socket, the inner telescopic block inside the electrode socket connects to the circuit direct connection board through the side connecting block and the electrical connection patch, thereby bypassing the energy meter to directly connect to the circuit, ensuring that the power supply is not affected, and thus realizing the replacement and maintenance of the energy meter while it is powered on, improving work efficiency.

[0020] 5. This invention can complete the distribution and connection of the circuit harness before the installation of the electricity meter, realize the function of pre-wiring, avoid the problem of hindering subsequent wiring due to the installation of the electricity meter first, reduce the installation difficulty, and improve the installation efficiency.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] This invention provides, for example Figures 1-12The diagram shows a high-heat-dissipation electricity metering box, comprising a base 1, a box body 2 externally connected to the base 1, and a waterproof frame and waterproof strip between the base 1 and the box body 2. Ventilation windows are provided on both sides of the box body 2. A door 3 is hinged to the side of the box body 2 away from the base 1, and a lock body and waterproof strip are provided between the door 3 and the door. A mounting base 4, consisting of multiple horizontal frames and two vertical frames, is bolted to the outside of the base 1 and located inside the box body 2. A wire-passing groove is provided on the end of the base 1 near the mounting base 4. Multiple electricity meters 5 are connected to the multiple horizontal frames of the mounting base 4. Each electricity meter 5 has mounting ears at its four corners near the mounting base 4, and a terminal block is provided on the lower end of the electricity meter 5 near the mounting base 4, with two terminals inside the terminal block. The electricity meters 5 are connected to the mounting base 4. The metering box is equipped with a wiring assembly, and the electricity meter 5 can be quickly installed and removed from the circuit through the wiring assembly. The assembly can control heat dissipation and circuit connection path according to the installation and removal. The wiring assembly consists of an installation mechanism, an alignment mechanism, and an electrical connection mechanism. An independent heat dissipation assembly is provided between the mounting base 4 and the installation mechanism. The independent heat dissipation assembly can be opened and closed through the installation and removal of the installation mechanism, and can independently dissipate heat from the electricity meter 5. The electricity metering box consists of a box base 1, a box body 2, and a box door 3. The lower end of the box body 2 is provided with a conduit for wire threading. Wiring can be pre-wired between the box base 1 and the mounting base 4 through the wire threading groove opened on the outside of the box base 1 and the electrical connection mechanism of the wiring assembly. The wiring harness can be connected before the electricity meter 5 is installed, avoiding the obstruction of wiring and wiring harness connection caused by installing the electricity meter 5 first.

[0036] Among them, the electricity meter 5 can be quickly installed and removed from the mounting base 4 through the installation mechanism of the wiring assembly, and can be connected and disconnected from the circuit during the installation and removal process through the alignment mechanism and the electrical connection mechanism. At the same time, the electricity meter 5 can open and close the independent heat dissipation component during the installation and removal process, so that the independent heat dissipation component can be opened when the electricity meter 5 is installed to provide precise and individual heat dissipation for the electricity meter 5, and closed when the electricity meter 5 is removed to avoid wasting airflow.

[0037] In addition, electricity meters 5 of different sizes but with the same aspect ratio can be installed through the installation mechanism and wiring assembly, and through the wiring assembly and mounting base 4, so that electricity meters 5 of different sizes but with the same aspect ratio can be successfully installed inside the electricity metering box.

[0038] In addition, the two terminals inside the lower terminal block of the energy meter 5, which are different in size but have the same aspect ratio, are spaced differently. The alignment mechanism can make electrical connections by adjusting the energy meter 5 with different terminal spacing. This allows the energy meter 5, which are different in size but have the same aspect ratio, to be electrically connected to the electrical connection mechanism. This ensures that the energy meter 5 can be smoothly and quickly connected to the circuit. When the alignment mechanism and the electrical connection mechanism are connected, the energy meter 5 is connected in series in the circuit. When the alignment mechanism and the electrical connection mechanism are connected, the energy meter 5 is disconnected from the circuit and the circuit is automatically reconnected through the electrical connection mechanism. This allows the energy meter 5 to be removed, maintained, or replaced without interrupting the power supply to the circuit.

[0039] like Figure 3 and Figure 10 As shown, the installation mechanism includes a mounting plate 6. The mounting plate 6 is positioned between the mounting base 4 and the electricity meter 5. The mounting plate 6 is installed on the end of the mounting base 4 away from the housing 1 using bolts and nuts. Adjustment grooves 7 are provided at each of the four corners of the mounting plate 6 near the electricity meter 5. Adjustment screws 8 extending to the outside are engaged inside the adjustment grooves 7 and are slidably connected to them. The adjustment screws 8 pass through the mounting ears of the electricity meter 5 and are fixed with nuts. During the installation of electricity meters 5 of different sizes but with the same length-to-width ratio, the adjustment screws 8 can adjust the position... The slide groove 7 slides towards the center of the mounting plate 6, so the four adjusting screws 8 at the four corners of the mounting plate 6 can slide inward or outward with the same length-to-width ratio, allowing the four adjusting screws 8 to smoothly pass through the mounting ears of the different-sized but same-length-to-width electricity meters 5, thereby fixing the different-sized but same-length-to-width electricity meters 5 to the center of the mounting plate 6, and installing and fixing them with the mounting plate 6, studs, nuts and mounting base 4, ensuring that the different-sized but same-length-to-width electricity meters 5 can be smoothly installed inside the electricity metering box and fixed to the center of the mounting plate 6.

[0040] like Figure 1 , Figure 10 , Figure 11 and Figure 12As shown, the independent heat dissipation component includes heat dissipation through holes 30. Multiple heat dissipation through holes 30 are provided on multiple crossbars of the mounting base 4, located on the mounting plate 6 near the end of the mounting base 4. A heat dissipation vent is provided in the middle of the mounting plate 6, and multiple heat dissipation grooves 31 communicating with the heat dissipation vent are provided on the outer side of the mounting plate 6 near the energy meter 5. Multiple opening push rods 32, inserted into the heat dissipation through holes 30, are connected to the outer side of the heat dissipation vent of the mounting plate 6 near the mounting base 4. Multiple limiting rods 33, connected to the inside of the mounting base 4, are provided on the outer side of the heat dissipation through holes 30 away from the mounting plate 6. A sealing plate 34, located inside the mounting base 4 and in contact with the multiple opening push rods 32, is slidably connected to the inner side of the multiple opening push rods 32. A sealing spring 35 is provided on the outer side of the sealing plate 34 away from the mounting plate 6. A suction pipe 3 extending to the outer side of the lower end of the housing 2 is connected to one side of the lower end of the mounting base 4. 6. A suction motor 37 is provided at the upper end of the suction pipe 36 and is electrically connected to the circuit through a wiring harness. Multiple suction fan blades 38 located inside the suction pipe 36 are connected to the lower end of the suction motor 37 through an output shaft. A filter screen 39 connected to the lower end of the suction pipe 36 is provided on the lower side of the suction fan blades 38. During the independent heat dissipation of the power meter 5, when the mounting plate 6 on which the power meter 5 is installed is fixed to the outside of the mounting base 4, the heat dissipation port of the mounting plate 6 is located outside the heat dissipation through hole 30. At the same time, multiple opening push rods 32 are inserted into the heat dissipation through hole 30 and push the sealing plate 34 that is blocking the heat dissipation through hole 30 into the mounting base 4, thereby opening the heat dissipation through hole 30, allowing the heat dissipation port of the mounting plate 6 to communicate with the inside of the mounting base 4 through the heat dissipation through hole 30, and to communicate with the outside of the power meter 5 through multiple heat dissipation slots 31.

[0041] At this time, the suction motor 37 is started, and the multiple suction fan blades 38 are driven to rotate inside the suction pipe 36 through the output shaft, thereby generating an inward suction force to draw the external cold air into the suction pipe 36 and guide it into the mounting base 4 through the suction pipe 36. The air is then filtered through the filter screen 39, allowing the mounting base 4 to guide the cold air into the heat dissipation port of the mounting plate 6 through the heat dissipation holes 30 opened on the crossbar. The air is then guided into the multiple heat dissipation slots 31 through the heat dissipation ports inside the mounting plate 6, thereby evenly guiding the cold air into the outside of the power meter 5, achieving precise individual heat dissipation for the power meter 5. Finally, the hot air inside the cabinet 2 is discharged through the heat dissipation windows opened on both sides.

[0042] In addition, the sealing plate 34 inside the heat dissipation hole 30 at the location where the electricity meter 5 is not installed is sealed inside the heat dissipation hole 30 under the action of the sealing spring 35, blocking the connection between the heat dissipation hole 30 and the heat dissipation port of the mounting plate 6, and preventing the waste of air power.

[0043] like Figures 2-6As shown, the alignment mechanism includes an alignment seat 9. The alignment seat 9 is located at the lower end of the terminal block of the energy meter 5. Two height adjustment electrode sleeves 10 are symmetrically arranged inside the upper end of the alignment seat 9 and fixed with bolts. Electrode plugs 11 extending to the outside of the alignment seat 9 are connected to the lower side of the two height adjustment electrode sleeves 10 near the mounting base 4. Screw slots 12 are provided at the ends of the two height adjustment electrode sleeves 10 away from the mounting base 4. A height adjustment electrode rod 13 is inserted into the upper end of the height adjustment electrode sleeve 10 and fixed with screws. A screw groove is provided on the alignment seat 9 corresponding to the screw slot 12. The fixing screw of the height adjustment electrode rod 13 passes through the screw slot 12 and slides within the screw groove. An electrode base 14 is connected to the upper end of the height adjustment electrode rod 13, and the electrode base 14 is close to the mounting base 4. One end is provided with an adjustment gap groove 15, and an electrode plate 16 is slidably connected inside the electrode base 14 and the adjustment gap groove 15 and fixed by bolts. The upper end of the electrode plate 16 is installed on the terminal block of the power meter 5 by bolts and connected to the terminal block. The electrode base 14 is covered with a protective shell 17. During the connection of the power meter 5 and the alignment mechanism, the two terminals inside the terminal block at the lower end of the power meter 5 are connected to the two electrode plates 16 by bolts respectively, so that the power meter 5 can be connected to the electrode base 14 through the electrode plate 16, and connected to the electrode plug 11 through the height adjustment electrode sleeve 10 and the height adjustment electrode rod 13. The position of the two electrode plates 16 can be adjusted according to the distance between the two terminal blocks and the distance between the terminal block and the electrical connection mechanism.

[0044] At this time, the electrode plate 16 can be adjusted by sliding inside the electrode base 14 and the adjusting gap groove 15 according to the spacing between the terminals, and is fixed by bolts. The electrode plate 16 can also be adjusted up and down by sliding the adjusting electrode rod 13 inside the adjusting electrode sleeve 10 according to the spacing between the terminals and the electrical connection mechanism, and is fixed by bolts. This allows the alignment mechanism to connect with energy meters 5 of different sizes, and to adjust its position according to the spacing between the energy meters 5 and the electrical connection mechanism, ensuring that energy meters 5 of different sizes can be accurately connected to the electrical connection mechanism during installation.

[0045] like Figure 5 , Figure 7 and Figure 8As shown, the electrical connection mechanism includes an electrical connection base 18. The electrical connection base 18 is bolted to the outside of the mounting base 4 and is located on the lower side of the terminal block of the electricity meter 5. An electrical connection slot 19 is provided on the upper end of the electrical connection base 18 away from the mounting base 4. An electrode socket 20 is provided inside the upper end of the electrical connection slot 19 near the mounting base 4 and is fixed with bolts. An alignment seat 9 is snapped into the electrical connection slot 19 and fits against the electrode socket 20. Electrode insertion sleeves 21 are symmetrically arranged inside the electrode sockets 20 near the alignment seat 9. Both electrode insertion sleeves 21 have internal telescopic blocks 22 slidably connected inside. Two electrode plugs 11 are respectively inserted into the two electrode insertion sleeves 21. The electrode plug 21 is fitted with two inner telescopic blocks 22 respectively. Each inner telescopic block 22 is equipped with a telescopic spring 23 at the end away from the electrode plug 11. The lower end of the electrode plug sleeve 21 is connected to a wire connecting tube 24 that passes through the lower end of the electric connection base 18. During the process of connecting the electric connection mechanism with the circuit, before the power meter 5 is installed, the electric connection mechanism is installed on the outside of the mounting base 4 at the corresponding position, and the corresponding wire harness in the circuit is inserted into the two wire connecting tubes 24 and then fixed with bolts. This allows the wiring to be completed in advance before the power meter 5 is installed, avoiding the power meter 5 after installation from hindering the wiring, reducing the wiring difficulty, and improving the wiring efficiency.

[0046] Furthermore, during the connection process between the electrical connection mechanism and the alignment mechanism, the energy meter 5 is installed at the center of the mounting plate 6 away from the mounting base 4 via the mounting assembly and is connected to the alignment mechanism. When the energy meter 5 is mounted outside the mounting base 4 via the mounting plate 6, the alignment base 9 of the alignment mechanism is inserted into the electrical connection slot 19 of the electrical connection mechanism. At the same time, the two electrode plugs 11 protruding from the outside of the alignment base 9 are inserted into the two electrode plug sleeves 21 and push the inner telescopic block 22 backward, allowing the energy meter 5 to connect with the electrode plug sleeves 21 and the wire connecting tube 24 through the alignment mechanism, and to the wiring harness in the circuit. This allows the alignment mechanism to achieve a precise connection with the electrical connection mechanism through the insertion between the electrode plugs 11 and the electrode plug sleeves 21, connecting the energy meter 5 to the circuit. Conversely, the electrode plugs 11 are pulled out from inside the electrode plug sleeves 21, disconnecting the connection between the energy meter 5 and the circuit.

[0047] like Figure 5 and Figure 9As shown, a side sliding groove 25 is provided at one end of the electrode plug sleeve 21 near the other electrode plug sleeve 21, and a side connecting block 26 connected to the outside of the inner telescopic block 22 is slidably connected inside the side sliding groove 25. An electrical connection patch 27 is slidably connected inside the side connecting block 26 away from the inner telescopic block 22. Multiple contact springs 28 are provided at the end of the electrical connection patch 27 near the inner telescopic block 22, and the patch is attached to the inner wall of the electrode socket 20 through the multiple contact springs 28. A circuit direct connection plate 29 is provided inside the electrode socket 20 near the alignment seat 9, located on the front side between the two side sliding grooves 25. The circuit direct connection plate 29 is close to the opening of the two electrode plug sleeves 21 and does not contact the two electrode plug sleeves 21. During the process of removing, maintaining or replacing the power meter 5, the power meter 5 is removed from the outside of the mounting base 4, and the alignment is moved. The mechanism separates from the electrical connection mechanism, allowing the electrode plug 11 to be pulled out from inside the electrode socket 21. This prevents the inner telescopic block 22 inside the electrode socket 21 from being pushed. Under the action of the telescopic spring 23, the inner telescopic block 22 slides towards the opening of the electrode socket 21, and drives the side connecting block 26 and the electrical connection patch 27 to slide towards the opening of the electrode socket 21. Before the electrode plug 11 is completely pulled out from inside the electrode socket 21, the electrical connection patch 27 is attached to the circuit direct connection plate 29 under the action of the attachment spring 28. This allows the two electrode sockets 21 to be connected through the middle circuit direct connection plate 29 before the energy meter 5 is removed, bypassing the energy meter 5 to directly connect to the circuit. This ensures that the circuit remains connected after the energy meter 5 is removed, thereby enabling the removal, maintenance, or replacement of the energy meter 5 without interrupting the power supply.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
