Description

Technical Field

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

[0002] Existing electricity metering equipment is mainly divided into two categories: one is fixed household electricity meters, which are usually installed in distribution boxes by the power department. They require professional electricians to connect the wires when the power is off, and the installation location is fixed and cannot be moved; the other is portable metering boxes designed for temporary power use scenarios. Although they have a certain degree of mobility, users or electricians still need to disconnect the power supply line and manually connect the current transformer or directly connect the metering module before use. This process involves the connection and insulation of exposed wires, which is not only cumbersome but also poses safety risks.

[0003] Whether fixed or portable, the installation or deployment of these devices relies on professional personnel to perform power-off operations. Ordinary users cannot safely and independently complete this task, which greatly limits their application in flexible scenarios such as temporary home monitoring, rental settlement, and energy efficiency auditing. Secondly, existing metering devices have a single function, designed solely for metering, and lack the ability to achieve uninterrupted power isolation and switching in the event of equipment failure or maintenance. This makes the metering device itself a single point of failure in the power supply chain. Once damaged, it will cause unexpected power outages to downstream electrical equipment, affecting the continuous operation of critical loads. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a portable, self-installing energy metering box, which solves the problem that existing energy metering boxes are not suitable for flexible application scenarios, and that a single failure of the energy metering component can cause power outages to downstream electrical equipment, causing many inconveniences to users.

[0021] 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. Example

[0022] like Figures 1-13 As shown, this embodiment of the invention provides a portable self-installing energy metering box for energy metering, particularly suitable for non-professional applications in flexible scenarios such as temporary home monitoring, rental settlement, and energy efficiency auditing; it includes a box body, an energy metering module 1, an input connector a, an output connector b, and a switching unit 7; as shown Figure 13 As shown, the input connector a-switching unit 7-output connector b constitute a bypass path (switching unit 7 is in the first working state), and the power metering module 1 is isolated, which is used in the early stage of equipment operation and when the power metering module 1 fails; the input connector a-switching unit 7-power metering module 1-output connector b constitute a metering path (switching unit 7 is in the second working state). During the safe operation phase of the equipment, the power metering module 1 performs power metering on the electrical equipment. The switching unit 7 is used to switch between the first working state and the second working state without power interruption, realizing the switching between the bypass path and the metering path, which can ensure the safety of equipment operation during application.

[0023] One feasible operating method is as follows: Adjust the switching unit 7 to the first working state to form a bypass path, connect the input connector a and the output connector b in series between the power supply and the electrical equipment, start the electrical equipment and after it runs smoothly, automatically control the switching unit 7 to adjust to the second working state to form a metering path to measure the power consumption of the equipment.

[0024] In one embodiment, a fault detection module (e.g., a temperature sensor) is arranged inside the power metering module 1. When the temperature inside the power metering module 1 is higher than a preset temperature threshold, it is determined that the power metering module 1 has a fault or is about to have a fault. When the fault detection module detects that the power metering module 1 has a fault or is about to have a fault, it sends a signal to the controller of the switching unit 7 to realize the transition from the first working state to the second working state.

[0025] The following describes the specific structural design of the portable self-installing energy metering box. The box includes a cable take-up box 3 and a connecting seat 2 fixed to the top of the cable take-up box 3. The cable take-up box 3 is used to store the wires from the input connector a, the output connector b, and the switching unit 7. For example, the input connector a uses a traditional male connector, and the output connector b uses a traditional female connector, which can efficiently match the electrical equipment currently used in homes, factories, etc. Both the cable take-up box 3 and the connecting seat 2 are integrally molded components. For example, they are made of plastic with insulating properties through injection molding. The lower part of the connecting seat 2 is a cover plate used to close the top opening of the cable take-up box 3, and the upper part of the connecting seat 2 forms a frame shape. The frame shape is adapted to install the energy metering module 1. For example, the energy metering module 1 is designed as a cylinder, with the two ends of the cylinder for the inlet and outlet wires. The bottom of the connecting seat 2 is connected to the cable take-up box. The top opening of the housing 3 can be fixed by ultrasonic welding. The input connector a and the output connector b are used to connect to an external power source and to connect electrical equipment, respectively. The switching unit 7 is set inside the cable take-up housing 3 and has a first end c, a second end d, and a third end e. The first end c of the switching unit 7 is electrically connected to the input connector a, the second end d is electrically connected to the output connector b, and the third end e is electrically connected to the input end of the power metering module 1. The output end of the power metering module 1 is electrically connected to the output connector b. The switching unit 7 is configured to have two working states: In the first working state, the input connector a is directly connected to the output connector b through the switching unit 7 to form a bypass path; In the second working state, the input connector a is connected to the input end of the power metering module 1 through the switching unit 7 to form a metering path through the power metering module 1.

[0026] It is understood that the above scheme only describes that the switching unit 7 has a first terminal c, a second terminal d and a third terminal e. The commonly used wires are two-core (positive and negative) or three-core (positive, negative and ground wires). Those skilled in the art can design the switching unit 7 to have two or three discrete units based on the above working state, so as to realize two or three sets of first terminal c, second terminal d and third terminal e.

[0027] In one embodiment, such as Figure 2 , Figure 6 As shown, ear shells 4 are fixedly provided on both sides of the take-up box 3. The inner side of the ear shell 4 is connected to the interior of the take-up box 3, and the top of the ear shell 4 is higher than the top of the take-up box 3, forming an outer ear. The outer ear and the outer side of the connector 2 form a wire cavity channel. The wire led out from the end of the power metering module 1 enters the interior of the take-up box 3 through the wire cavity channel, and then connects to the input connector a, the output connector b and the switching unit 7.

[0028] In one embodiment, one of the ear shell parts 4 has a first notch 4a on its side for the wire between the input connector a and the first end c of the switching unit 7 to pass through. The first notch 4a is a channel structure. The other ear shell part 4 has a second notch 4b on its side for installing the output connector b. This structure is designed so that the output connector b can be installed at the second notch 4b, and the input connector a can also move freely (the connected guide passes through the first notch 4a).

[0029] The compact design of the cable tray 3, ear shell 4, and connecting base 2 eliminates the need for additional external wiring in the portable self-installing energy meter box, making it safer and more aesthetically pleasing.

[0030] In one embodiment, a relatively long wire is designed between the input connector a and the first end c of the switching unit 7, so that the portable self-installing energy meter box can be placed at a location far from the power source. The input connector a can be pulled to the power source to achieve connection and use, thereby improving the application range of the portable self-installing energy meter box.

[0031] Inside the cable take-up box 3, there is a cable management component 6 for organizing the wires between the input connector a and the first end c of the switching unit 7; this prevents the wires between the input connector a and the first end c of the switching unit 7 from getting tangled inside the cable take-up box 3 when the cable is stored, ensuring that the wires can be quickly taken out when in use and quickly stored when stored.

[0032] Specifically, the cable management assembly 6 includes: a number of fixed rollers 601 distributed in a straight line, a guide base plate 602, a guide frame 603, a movable roller 604, and an operating component 605.

[0033] For example, six fixed rollers 601 are designed, which are horizontal and close to the top of the take-up box 3. Each fixed roller 601 has a positioning port 601a on its outer side to restrict the guide from sliding along its axial direction. All six fixed rollers 601 are fixedly installed inside the take-up box 3. A guide base plate 602 is provided between two adjacent fixed rollers 601, with a total of five sets of guide base plates 602. A guide frame 603 is fixedly connected to the side of each guide base plate 602. The guiding direction formed by the guide frames 603 is perpendicular to the linear distribution direction of the fixed rollers 601, corresponding to the guide base... Both plate 602 and guide frame 603 are vertical, and the guiding direction of guide frame 603 is also vertical. The top of guide frame 603 is slightly higher than the position of fixed roller 601. Movable roller 604 corresponds to guide frame 603 one by one. One end of movable roller 604 is slidably engaged with guide frame 603, and the other end of movable roller 604 is fixedly installed with operating component 605. Operating component 605 is slidably engaged with sliding elongated opening 606 on the side of take-up box 3, and operating component 605 has an operating part located on the outside of take-up box 3. This operating part is used for manual operation by the user to slide movable roller 604 up and down.

[0034] like Figure 6 , Figure 7 As shown, the guide between the input connector a and the first end c of the switching unit 7 is wound above the fixed roller 601 and below the movable roller 604. When the operating member 605 slides upward, the length of the wire wound between the fixed roller 601 and the movable roller 604 is small. At this time, the input connector a can extend outward a longer distance with the wire, which is suitable for situations where the power source is far away. Conversely, when the movable roller 604 is slid downward, the length of the wire wound between the fixed roller 601 and the movable roller 604 increases, and the distance that the input connector a can extend outward with the wire decreases. At this time, most of the wire can be stored inside the take-up box 3.

[0035] In one embodiment, a linkage limiter is also designed in the cable management assembly 6 to limit the movement of adjacent movable rollers 604, so that the cable is arranged more neatly.

[0036] Specifically, the linkage limiting components include: limiting plate 607, positioning component 608, and elastic limiting component.

[0037] The limiting plate 607 is rotatably mounted on the inner wall of the take-up box 3 at its center, and the limiting plate 607 is located in the area between two adjacent sliding elongated openings 606, such as... Figure 7As shown, the limiting plate 607 is in a vertically inclined state at a small angle; the positioning member 608 and the elastic limiting member are installed on the inner wall of the take-up box 3 and located on both sides of the limiting plate 607, so that the limiting plate 607 can rotate unidirectionally in one direction. For example, the positioning member 608 is located diagonally above the limiting plate 607, the elastic limiting member is located diagonally below the limiting plate 607, and one end of the limiting plate 607 is located above the bottom end of the sliding elongated opening 606 on its first side, and the other end is located above the top end of the sliding elongated opening 606 on its second side.

[0038] When the first movable roller 604 on the side closest to input connector a has not moved to the top, the second movable roller 604 on the side closest to input connector a is restricted from sliding upward by the bottom of the limiting plate 607. When the first movable roller 604 on the side closest to input connector a moves to the top, it pushes the top of the limiting plate 607 upward, causing the limiting plate 607 to rotate at a certain angle. The bottom of the limiting plate 607 no longer restricts the corresponding movable roller 604, thus allowing the second movable roller 604 on the side closest to input connector a to slide upward. Based on the above principle, the movable rollers 604 on the side closest to input connector a can be ordered sequentially as follows: ① ② ③ ④ ⑤ ⑥. After movable roller 604 ① moves to the top, movable roller 604 ② can move upward. After movable roller 604 ② moves to the top, movable roller 604 ③ can move upward, and so on, restricting movable rollers 604 ③ ④ ⑤ ⑥ in sequence.

[0039] In one embodiment, the elastic limiting member includes: a positioning shaft 609 and an elastic ring 6010 sleeved on the outside of the positioning shaft 609. One end of the positioning shaft 609 is fixedly connected to the inner wall of the take-up box 3. The radial thickness of the elastic ring 6010 is 20-35 mm. When the limiting plate 607 rotates, it compresses the elastic ring 6010, and the sidewall of the elastic ring 6010 is compressed and elastically deformed.

[0040] In one embodiment, the power metering module 1 includes: an inner housing 101, a voltage detection module 102, a current detection module 103, and a processing and display module 105 (including a microprocessor and an LCD display screen).

[0041] The inner housing 101 is a hollow cylinder. It is composed of two semi-circular housings joined together. Both ends have circular holes for wires to pass through. The inner housing 101 houses a voltage detection module 102 and a current detection module 103, which are used to detect current and voltage data respectively. The inner housing 101 has heat dissipation holes on its sides for heat dissipation. The processing and display module 105 is fixed to the outside of the inner housing 101 by heat shrink film. The processing and display module 105 is electrically connected to both the voltage detection module 102 and the current detection module 103. The heat shrink film is also wrapped around the outside of the inner housing 101 to ensure that the two semi-circular housings fit together tightly.

[0042] This structural design allows the processing and display module 105 to be located independently on the outside of the inner housing 101, minimizing the impact of the heat generated by the voltage detection module 102 and the current detection module 103 on the internal circuit chips of the processing and display module 105.

[0043] A connecting part 5 can also be designed on the side of the power metering module 1. The connecting part 5 has a part that snaps into the power metering module 1 and a magnetic plate. In this way, the connecting part 5 can be fixedly adsorbed on the side of the device (the side of the device is metal) by the processing equipment, so as to facilitate the placement of the portable self-installing power metering box.

[0044] In one embodiment, the switching unit 7 includes two sets of discrete units, each of which includes: a housing 701, two sets of contact members 706, an octahedral switching member 705, and a driving assembly.

[0045] Two sets of contact elements 706 are located inside the housing 701 and are symmetrically distributed. Both sets of contact elements 706 are elastically arranged along the line connecting them, meaning they have the function of elastically extending inwards and outwards. The two sets of contact elements 706 are connected to the second end d and the third end e, respectively. An octahedral switching element 705 is located inside the housing 701, between the two sets of contact elements 706. It is in contact (electrically connected) with one of the contact elements 706 or in contact with both contact elements 706. For example, as the octahedral switching element 705 moves upwards, it contacts the left contact element 706; when it moves to the middle position, it contacts both contact elements 706; continuing to move upwards, it separates from the left contact element 706 while maintaining contact with the right contact element 706. The octahedral switching element 705 specifically includes: a copper sheet 7053 and a spindle 7052. The octahedral insulating component 7051 and the bottom end of the spindle component 7052 are connected to the metal copper sheet 7053. The octahedral insulating component 7051 covers the outside of the metal copper sheet 7053 and the spindle component 7052. The top end of the spindle component 7052 is connected to the first end c. The metal copper sheet 7053 includes an integrally formed middle part 7053a, a first vertical part 7053b, a first inclined part 7053c, a second vertical part 7053d, and a second inclined part 7053e. 7053b, the first inclined portion 7053c, the second vertical portion 7053d, and the second inclined portion 7053e are centrally symmetrically distributed at both ends of the middle portion 7053a. The first inclined portion 7053c and the second inclined portion 7053e are both attached to the side of the octahedral insulating component 7051. The metal copper sheet 7053 is processed by copper sheet bending process. The driving component is a driving component located inside the housing component 701, which is used to drive the octahedral switching component 705 to move the housing component 701 up and down.

[0046] like Figure 8 As shown, the octahedral switching component 705 is in the lower position at this time, and its copper sheet 7053 is only in contact with the left contact component 706. At this time, the third end e is connected to the first end c. The driving component drives the octahedral switching component 705 to move upward. The center of the octahedral switching component 705 moves to the middle height position of the two sets of contact components 706. At this time, the second end d and the third end e are both connected to the first end c. As the octahedral switching component 705 continues to be driven upward, the copper sheet 7053 is only in contact with the right contact component 706. At this time, only the second end d is connected to the first end c, realizing uninterrupted switching.

[0047] In one embodiment, the drive assembly includes an electromagnetic component 703, a moving armature 704, and a guide seat 702.

[0048] The electromagnetic component 703 is fixedly connected to the inner wall of the housing 701 via a bracket. The electromagnetic component 703 is annular. The moving armature 704 cooperates with the electromagnetic component 703 and is located inside the electromagnetic component 703. The moving armature 704 is driven by the electromagnetic component 703 to move up and down. The top end of the moving armature 704 is fixedly connected to the bottom end of the spindle 7052 via an isolator 707. The isolator 707 serves as an electrical isolation element. The top end of the moving armature 704 is fixedly connected to the octahedral insulating element 7051. The guide seat 702 is fixedly connected to the inner bottom of the housing 701, and the bottom end of the moving armature 704 is slidably engaged with the guide seat 702.
