Description

Technical Field

[0001] This invention relates to the field of electricity metering box technology, specifically a modular electricity metering box. Background Technology

[0002] An electricity metering box is a device used to measure and meter electricity consumption. It is widely used in power supply and electricity management systems. Electricity metering boxes can provide accurate electricity metering and monitoring functions, which helps to monitor electricity usage in real time.

[0003] Currently, traditional wall-mounted electricity metering boxes generally use an integrated structure for installation and fixation (such as bolt fixing). The disassembly and assembly process is relatively cumbersome, and once the bolts loosen, the box is very likely to fall off. In addition, most existing integrated electricity metering boxes are directly installed on the wall, which causes the heat accumulated in the area to dissipate slowly, further increasing the energy consumption of active cooling (such as fans), which does not meet the requirements of energy conservation, environmental protection and green low-carbon development. Summary of the Invention

Detailed Implementation

[0019] 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.

[0020] The electricity metering box of this invention is an indispensable terminal component on the user side of the smart grid industry. It is used to carry and protect electricity metering elements and facilitate electricity management. The modular design of the electricity metering box is not only convenient to assemble and disassemble, but also highly stable, and meets the requirements of energy conservation, environmental protection and green low-carbon development.

[0021] Example 1 Refer to the instruction manual appendix Figures 1-2This embodiment is the first embodiment of the present invention, providing a modular power metering box. The front side of the box body 1 is divided into a power control area, a power metering area, and an outgoing line protection area. A convection gap is formed on the rear side of the box body 1. A heat-conducting rod 4 extending through to the front side is fixed inside the convection gap. The heat-conducting rod 4 includes two types, coarse and fine. The coarse heat-conducting rod 4 is set in the high heat generation area corresponding to the power control area, and the fine heat-conducting rod 4 is set in the secondary high heat generation area corresponding to the outgoing line protection area. This isolates the rear side of the box body 1 corresponding to the power control area and the outgoing line protection area, preventing the heat generated in the power control area from affecting the heat dissipation of the outgoing line protection area. Two sets of ventilation slots 2 are opened at the top and bottom of the box body 1, which respectively form heat dissipation channels for the high heat generation area and the secondary high heat generation area inside the convection gap, forming a "bottom in, top out" chimney effect. That is, air enters from the ventilation slot 2 at the bottom of the box body 1, takes away the heat inside the convection gap on the rear back plate of the box body 1 and the heat-conducting rod 4, and then exits from the top of the box body 1.

[0022] It should be noted that a cooling fan (not shown in the attached diagram) is also installed on the housing 1. As this is prior art, it will not be described in detail here. In this invention, the heat generated by the operation of the electronic components on the front side of the housing 1 is conducted to the convection gap area through the heat conduction rod 4, and natural convection heat dissipation is achieved by utilizing the convection gap between the rear side of the housing 1 and the mounting wall. This avoids the situation where poor active heat dissipation results in heat accumulation inside the housing 1, which in turn leads to increased power consumption of the active heat dissipation source, accelerated aging of components, and increased carbon emissions throughout the entire life cycle. This achieves efficient and sustainable heat dissipation, and achieves the environmental protection goal of "low energy consumption, low emissions, and long life".

[0023] Furthermore, such as Figure 1 , Figure 3 , Figure 7 and Figure 9As shown, a self-locking mounting base 5 is provided on the rear side inside the housing 1. The self-locking mounting base 5 consists of a pre-installation part and floating feet 56. The floating feet 56 are fixedly installed on the rear side inside the housing 1. The pre-installation part includes a base plate 51 and four guide blocks 52 fixed on one side of the base plate 51. The insertion end of the floating feet 56 is movably inserted into the rectangular cavity formed by the four guide blocks 52. A sealing component 53 is provided between two guide blocks 52 arranged vertically and collinearly, and a locking component 5 is provided on the opposite side of the two guide blocks 52 arranged vertically and collinearly. 4. The opposite sides of the four guide blocks 52 away from the substrate 51 are all set as arc surfaces. The four arc surfaces can also form an arc-shaped cavity larger than the insertion end of the floating foot 56, which is used to guide the insertion end of the floating foot 56 to be accurately inserted into the rectangular cavity surrounded by the four guide blocks 52. This solves the problem of inability to insert caused by the installation deviation of the pre-installation part of the self-locking mounting base 5. The two guide blocks 52 arranged vertically and collinearly have through slots in the middle of the end near the substrate 51, and the sealing component 53 is set between the two through slots.

[0024] Furthermore, two guide blocks 52 arranged vertically and collinearly each have a horizontal through-slot 55 on one side. Each through-slot 55 has a clamping component 57 at both ends inside for assisting in limiting the floating foot column 56 when it is released from its locked state. The side of the box 1 has a socket 3 of the same specification as the through-slot 55 at the position corresponding to each through-slot 55. The electricity metering box also includes a top frame for releasing the floating foot column 56 from its locked state. One end of the top frame that is inserted into the box 1 is adapted to the socket 3.

[0025] It should be noted that, according to the distribution position of the floating feet 56 on the rear side of the housing 1, the present invention can install a pre-installation part for inserting the floating feet 56 on the corresponding mounting wall, so that the housing 1 can be directly inserted during installation, which is convenient and quick to install and disassemble.

[0026] Furthermore, such as Figure 3 and Figure 6 As shown, the sealing assembly 53 includes a protrusion 531 fixed in the middle of the substrate 51. The top and bottom of the protrusion 531 are provided with movable blocks 532 that pass through the corresponding through grooves. A spring 533 is fixedly connected between the opposite end of the two movable blocks 532 and the corresponding side of the protrusion 531. The opposite ends of the two movable blocks 532 away from the substrate 51 are inclined. At the same time, a recessed groove is opened on the opposite side of the two movable blocks 532 facing the substrate 51. When the two springs 533 are in the natural state, the opposite ends of the two movable blocks 532 still pass through the corresponding through grooves, but do not block the area of ​​the mounting bolts on the substrate 51.

[0027] It should be noted that during the insertion of the floating foot 56 into the rectangular cavity formed by the four guide blocks 52, the insertion end of the floating foot 56 is used to press the inclined surfaces of the opposite ends of the two movable blocks 532, causing the two movable blocks 532 to move in opposite directions under the pressure of the insertion end of the floating foot 56, and stretching the corresponding spring 533 to store force. The movable blocks 532 that are pushed out under the pressure of the insertion end of the floating foot 56 will abut against the bolt ends of the fixing base plate 51 to prevent the bolts of the fixing base plate 51 from loosening, thereby improving the installation stability of the pre-installation seat.

[0028] Furthermore, such as Figures 3-4 and Figures 6-7 As shown, the positioning assembly 54 includes a T-shaped cylinder 542 fixed on the opposite side of two guide blocks 52 arranged vertically and collinearly. Lifting plates 541 are movably sleeved on the outer side of each of the two T-shaped cylinders 542, and springs 543 located on the opposite side of the two lifting plates 541 are also sleeved on the outer side of the two T-shaped cylinders 542. When the two springs 543 are in their natural state, the two lifting plates 541 are in contact with the surface of the corresponding guide block 52 under the action of the corresponding springs 543.

[0029] Furthermore, the locking assembly 54 also includes a vertical groove formed in the middle of two guide blocks 52 arranged vertically and collinearly. Each of the two lifting plates 541 has a locking block 544 fixedly provided on its opposite side, which is movably inserted into the corresponding vertical groove. Each of the two locking blocks 544 has a through groove 545 arranged vertically and coplanarly with the corresponding through groove 55. Each of the two through grooves 545 is composed of a connected triangular groove and a rectangular groove. The rectangular groove on the through groove 545 has the same cross-sectional shape as the through groove 55 on the corresponding guide block 52. The opposite ends of the two locking blocks 544 are inclined on the side away from the corresponding base plate 51, so that when the insertion end of the floating foot 56 is inserted into the rectangular cavity formed by the four guide blocks 52, the two locking blocks 544 can be pushed to move in opposite directions during the advancement of the insertion end of the floating foot 56.

[0030] It should be noted that during the self-locking process of the floating foot post 56 insertion end inserted into the rectangular cavity formed by the four guide blocks 52 using the locking component 54, the insertion of the floating foot post 56 insertion end presses the inclined surface on the two locking blocks 544, causing the two locking blocks 544 to move in opposite directions under the pressure of the floating foot post 56 insertion end. This causes the corresponding two lifting plates 541 to press the spring 543 at their respective positions in opposite directions until the opposite ends of the two locking blocks 544 retract into their respective vertical grooves. At this time, the insertion end of the floating foot post 56 can be smoothly inserted into the rectangular cavity formed by the four guide blocks 52. When the insertion end of the floating foot post 56 is in place, the two locking blocks 544 will be inserted into the limiting groove on the insertion end of the floating foot post 56 under the restoring force of the corresponding spring 543, thereby locking and locking the insertion end of the floating foot post 56.

[0031] Furthermore, such as Figure 4 and Figures 7-8 As shown, the clamping assembly 57 includes a receiving groove 571 opened inside the corresponding through groove 55. The receiving groove 571 is composed of two through square grooves, and the two square grooves are designed in a concentric stepped shape. One square groove has a boss 572 with inclined ends movably fitted inside it. The other square groove has a movable frame 573 movably fitted inside it. A rubber roller 576 is rotatably installed on the side of the movable frame 573 away from the boss 572. The rubber roller 576 cannot rotate when there is no external force or the external force is small. Elastic telescopic columns 1 574 are fixedly installed between the four corners of the side of the boss 572 facing the movable frame 573 and the end face of the inner cavity of the corresponding square groove. Elastic telescopic columns 2 575 are fixedly installed between the opposite side of the boss 572 and the movable frame 573.

[0032] Furthermore, the elastic telescopic column 574 is composed of a sleeve rod fixedly connected to the boss 572, a sleeve fixedly connected to the end face of the corresponding square groove cavity, and a connecting spring fixedly connected to the end face of the square groove cavity and the boss 572. The end of the sleeve rod near the sleeve is movably inserted into the inside of the sleeve, and the connecting spring is set on the outside of the sleeve rod and the sleeve. The second elastic telescopic column 575 consists of a second sleeve rod fixedly connected to the boss 572, a second sleeve fixedly connected to the movable frame 573, and a second connecting spring fixedly connected to the movable frame 573 and the boss 572. The end of the second sleeve rod near the second sleeve is movably inserted into the inside of the second sleeve, and the second connecting spring is sleeved on the outside of the second sleeve rod and the second sleeve. The elastic coefficient of the second connecting spring is greater than the elastic coefficient of the first spring 533.

[0033] It should be noted that during the process of inserting the top frame into the socket 3 on the housing 1 to release the locking assembly 54 from locking the floating foot 56, the two movable blocks 532, which reset under the restoring force of the spring 533 during the resetting of the sealing assembly 53, will exert a pushing force on the unlocked floating foot 56, causing the floating foot 56 to quickly disengage from the rectangular cavity formed by the four guide blocks 52. This could easily cause the housing 1 to fall. At this time, it is necessary to use the tightening assembly 57 to press down the floating foot 56 to prevent it from popping out automatically. Specifically: During the insertion of the top frame into the socket 3 on the housing 1, when the insertion end on the top frame enters the slot 55 on the corresponding guide block 52 and contacts the boss 572 in its natural state, as the insertion end on the top frame continues to advance, it will gradually squeeze the boss 572, causing the boss 572 to contract into the corresponding square slot and compress the elastic telescopic column 1 574, thereby driving the movable frame 573 to push out of the corresponding square slot. If the movable frame 573 pushed out of the corresponding square slot is blocked by the insertion end of the floating foot column 56, as the insertion end on the top frame continues to advance, the insertion end of the floating foot column 56 will press the rubber roller 576 on the movable frame 573 in the opposite direction, causing the elastic telescopic column 2 575 to be compressed, ensuring that the rubber roller 576 is tightly pressed against the surface of the insertion end of the floating foot column 56, so as to prevent the two movable blocks 532 during the reset process from popping out the insertion end of the floating foot column 56 in the unlocked state, and preventing the housing 1 in the unlocked state from falling. Furthermore, during the process of the top frame inserting into the slot 545 on the card block 544, it will first move inside the triangular slot, causing the two card blocks 544 to move in opposite directions under the pressure of the corresponding insertion ends, so that the card blocks 544 release the lock on the insertion end of the floating foot column 56. Then, the box 1 can be separated from the pre-installed part.

[0034] Furthermore, such as Figure 3 and Figures 5-6 As shown, the floating foot column 56 includes an insert block 561. A cross groove 562 is provided at one end of the insert block 561 near the housing 1. A cross plate 563 is movably inserted into the cross groove 562. The thickness of the cross plate 563 is adapted to the thickness of the cross groove 562 to prevent the cross plate 563 from moving along the feed direction of the insert block 561. Each of the four ends of the cross plate 563 extending outside the cross groove 562 is fixedly provided with an end block 564 fixedly connected to the housing 1. A retaining ring 565 is movably sleeved on the outer side of each of the four ends of the cross plate 563 extending outside the cross groove 562. A spring 566 sleeved on the outside of the cross plate 563 is fixedly connected between each retaining ring 565 and the corresponding end block 564. The retaining ring 565 is in contact with the outer side of the insert block 561 under the action of the corresponding spring 566, and the elastic coefficients of the multiple springs 566 are consistent.

[0035] Furthermore, the insert 561 has a slot 568 in the middle of the end away from the corresponding substrate 51. The slot 568 is adapted to the protrusion 531 on the sealing assembly 53 to prevent the presence of the protrusion 531 from affecting the feed of the insert 561. The insert 561 also has a slot 567 (i.e. the aforementioned limiting slot) that is adapted to the card block 544 through the middle. The top and bottom of the end of the insert 561 near the corresponding substrate 51 are inclined, so that the inserted insert 561 can be better used to squeeze the card block 544.

[0036] It should be noted that during the process of inserting the plug end of the floating foot 56 into the rectangular cavity formed by the four guide blocks 52, if there is a slight deviation in the installation position of the substrate 51, the plug end of the plug 561 will first contact the arc surface on the guide block 52 during the insertion into the rectangular cavity. As the plug 561 is inserted, the arc surface on the guide block 52 will press the plug 561 in the opposite direction, causing the plug 561 to move along the cross plate 563. At the same time, the spring 3 566 in its moving direction will be compressed to adjust the position of the plug 561, ensuring that the plug 561 is accurately inserted into the rectangular cavity formed by the four guide blocks 52. This design of the floating foot 56 can effectively avoid the problem that the plug 561 cannot be plugged into the pre-installed part due to the installation error of the substrate 51, thus improving the installation efficiency.

[0037] Example 2 Refer to the instruction manual appendix Figures 3-5 This embodiment is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that: conductive posts 10 are fixedly provided through the plug 561 corresponding to the power control area and the outgoing line protection area on the rear side inside the housing 1, and a grounding terminal post 12 is fixedly provided on one side of the substrate 51 on which the conductive posts 10 are installed. A metal spring 11 is also provided on the rear side inside the housing 1, which is directly opposite to the substrate 51 on which the conductive posts 10 are installed. The end of the conductive post 10 near the metal spring 11 is always in contact with the metal spring 11. The contact surface of the metal spring 11 covers the area where the plug 561 floats, so that when the substrate 51 has an installation deviation, the conductive post 10 and the metal spring 11 can still be kept in contact.

[0038] It should be noted that during the process of inserting the plug 561 into the rectangular cavity formed by the four guide blocks 52, when the plug 561 is inserted and locked by the automatically reset locking block 544, the end of the conductive post 10 away from the metal spring 11 comes into contact with the grounding terminal post 12 on the corresponding substrate 51, so that the grounding is connected and the effect of plugging and grounding is achieved.

[0039] Example 3 Refer to the instruction manual appendix Figure 2This embodiment is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that: the power control area, the power metering area and the outgoing line protection area inside the box 1 are all provided with mounting base plates 6 and clamping posts 7 fixed at the four corners of the corresponding areas. The mounting base plates 6 are installed in the corresponding areas inside the box 1 through the four clamping posts 7 at their respective positions.

[0040] It should be noted that the present invention improves installation convenience by fixing the mounting base plate 6 to the corresponding area using the clamping post 7, thus breaking through the traditional bolt fixing method.

[0041] Furthermore, such as Figure 2 and Figure 10 As shown, the locking post 7 includes a round rod 71 fixed inside the housing 1. One end of the round rod 71 has a cylindrical groove. The inner end of the cylindrical groove has four evenly distributed annular through holes. A stop 73 is installed inside the cylindrical groove at the position corresponding to the through holes. An elastic element 76 is provided at the outer end of the round rod 71. A push post 72 is movably inserted inside the cylindrical groove. The end of the push post 72 near the stop 73 is set with an arc surface structure, and a knob is provided at the end of the push post 72 away from the stop 73. The maximum diameter of the knob is smaller than the diameter of the round rod 71. Two collinear stop rods 75 are fixedly provided on the outer side of the push post 72. One end of the round rod 71 has two J-shaped grooves 74 that are centrally symmetrical about the push post 72. The two stop rods 75 are slidably connected to the corresponding J-shaped grooves 74.

[0042] Furthermore, the stop 73 includes a square post fixed at the center of the end face of the cylindrical groove. A straight spring is fixedly connected between the square post and the arc end of the push post 72. The stop 73 also includes a stop bar that is movably inserted into the four through holes. A straight spring is fixedly connected between each stop bar and the corresponding side of the square post. When the straight spring is in its natural state, the four stop bars are hidden inside the through holes under the action of the corresponding straight spring, while the stop bar 75 installed on the push post 72 is at the entrance end of the corresponding J-shaped groove under the action of the straight spring. The elastic element 76 consists of a fixed ring, a moving ring, and a straight spring three fixedly connected between the fixed ring and the moving ring. The fixed ring is fixedly sleeved on the outside of the round rod 71, while the moving ring is movably sleeved on the outside of the round rod 71. The straight spring three is also sleeved on the outside of the round rod 71. When the straight spring three is in its natural state, the minimum distance between the moving ring and the stop bar is less than the thickness of the mounting base plate 6. In this way, the mounting base plate 6 can be installed by using the pushed-out stop bar in conjunction with the moving ring pressed by the straight spring three.

[0043] It should be noted that when installing the mounting base plate 6 to the various areas on the front side of the housing 1, first align the mounting holes on the mounting base plate 6 directly with the round rod 71 inside the designated area, and push the mounting base plate 6 to press the moving ring along the axial direction of the round rod 71. Then, push the push column 72 towards the elastic member 76, so that the stop rod 75 moves synchronously to the other end of the transverse groove on the corresponding J-shaped groove 74. At the same time, use the arc end of the push column 72 to simultaneously press the four stop bars, so that the stop bars pass through the corresponding through holes, and stop the mounting base plate 6 that has been reset and pushed by the elastic member 76. Then, rotate the push column 72 to deflect the stop rod 75 to another transverse groove. Then, remove the external force, and use the reset elastic member 76 to hold the stop rod 75 against the inside of the deflected transverse groove. In this way, the purpose of quickly assembling and disassembling the mounting base plate 6 can be achieved.

[0044] Example 4 Refer to the instruction manual appendix Figure 2 This embodiment is the fourth embodiment of the present invention. The difference between this embodiment and the third embodiment is that: a second mounting bracket 9, an energy meter mounting bracket and a first mounting bracket 8 are respectively installed on one side of the mounting base plate 6 inside the power control area, the energy metering area and the outgoing line protection area of ​​the housing 1. A wire harness for binding the wires is also installed on one side of the mounting base plate 6 inside the energy metering area.

[0045] It should be noted that by dividing the front side of the housing 1 into three areas, the present invention can avoid electrical and thermal interference between the areas and facilitate subsequent targeted maintenance.

[0046] Furthermore, such as Figure 2 and Figure 11 As shown, the mounting frame 8 includes two track frames 81 fixed on the corresponding mounting base plate 6 and a mounting platform 82 located between the two track frames 81. The relevant components of the outgoing line protection zone can be detachably installed on the mounting platform 82. The track groove on the track frame 81 is set with a cross-shaped structure. Straight rods 83 are fixedly provided on the top and bottom of both sides of the mounting platform 82. A ring plate 85 is movably sleeved on the outside of the lower straight rod 83. A spring 86 is fixedly connected between the ring plate 85 and the bottom end face of the corresponding track groove. When the spring 86 is in its natural state, the straight rods 83 on the mounting platform 82 are all located inside the track groove. A straight plate 84 is slidably connected to the outside of each straight rod 83 inside the track groove. The straight rod 83 at the upper end is fixedly connected to the straight plate 84, while the straight rod 83 at the upper end is movably sleeved with the straight plate 84.

[0047] It should be noted that during the installation of relevant electronic components on the outgoing line protection side, the mounting platform 82 is moved upward along the track groove, allowing the upper straight plate 84 to slide out of the corresponding track groove. Then, the mounting platform 82 is rotated at a certain angle around the lower straight rod 83 as the central axis. After the relevant installation and wiring operations are completed, the above process can be reversed. This can provide greater convenience for the disassembly, assembly, and wiring of electronic components.

[0048] Furthermore, such as Figure 2 and Figure 12 As shown, mounting bracket 2 9 includes an I-beam 91 fixedly connected to the corresponding mounting base plate 6 and mounting platform 2 92 located on one side of the I-beam 91. Mounting platform 2 92 has an I-beam platform 93 fixedly provided on the side facing the I-beam 91. Both ends of the inner side of the I-beam 91 are movably provided with inclined platforms 94. The end of the I-beam platform 93 facing the corresponding inclined platform 94 is inclined. Both ends of each inclined platform 94 are fixedly connected with curved rods 97 that are slidably installed on the I-beam 91. Elastic telescopic columns 3 95 are fixedly installed between the I-beam 91 and the two lower platforms 94, and elastic telescopic columns 4 96 are fixedly installed between the I-beam 91 and the I-beam platform 93. The relevant structural components of elastic telescopic columns 3 95 and elastic telescopic columns 4 96 are described in the aforementioned elastic telescopic column 1 574, and will not be repeated here.

[0049] It should be noted that during the installation of mounting bracket 2 9, by pushing the two inclined platforms 94, the corresponding curved rods 97 move in opposite directions and squeeze the corresponding elastic telescopic column 3 95. When the curved rods 97 move to align with the through holes on mounting bracket 2 92, the curved rods 97 pass through the corresponding through holes. At this time, the I-beam 93 will squeeze the elastic telescopic column 4 96. Then, the force on the inclined platforms 94 is removed, so that during the reset process, the two inclined platforms 94 drive the curved rods 97 to lock onto mounting bracket 2 92, making disassembly and assembly convenient and quick.

[0050] The installation process of the above-mentioned electricity metering box is as follows: First, according to the distribution position of the floating feet 56 on the rear side of the box body 1, a pre-installation part for inserting the floating feet 56 is installed on the corresponding mounting wall. Then, the insert 561 on the floating feet 56 is inserted into the rectangular cavity formed by the four guide blocks 52 under the guidance of the arc surface on the corresponding four guide blocks 52. The pushing insert 561 presses against the locking block 544, causing the two locking blocks 544 to move in opposite directions. During the pushing process, the end of the insert 561 that passes over the locking block 544 will also press against the two movable stops 532. When the insert 561 is pushed into the slot 567 on it and is directly opposite the locking block 544, The locking block 544 will be inserted into the slot 567 under the action of the corresponding spring 543, and complete the self-locking. At the same time as the self-locking is completed, the two movable blocks 532 will move in opposite directions under the pressure of the insertion block 561. The opposite ends of the two movable blocks 532 will seal the bolt head of the fixed base plate 51 at the location to prevent loosening. In addition, when the insertion block 561 is inserted into place, the end of the conductive post 10 away from the metal spring 11 will contact the grounding terminal post 12 on the corresponding base plate 51 to achieve the effect of plugging and grounding. Conversely, the locking state of the insertion block 561 can be quickly released by the matching top bracket, which improves the convenience of disassembling and assembling the housing 1.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
