Description

Technical Field

[0001] The present application relates to the technical field of meter boxes, and in particular to a meter box with a hidden wiring function. Background Art

[0002] In the field of electricity metering, meter boxes are essential and important equipment. They undertake the critical tasks of energy metering and circuit control and are widely used in various power usage scenarios. With the continuous growth of electricity demand and the increasing diversity of electrical equipment, higher requirements are being placed on the functionality and reliability of meter boxes. Meter boxes can meet the needs of centralized metering and management of multiple power circuits within a specific area, providing a fundamental guarantee for the stable operation and accurate metering of power systems.

[0003] In the related art, a meter box is mainly composed of a box body and a door installed on the box body. Its internal structure is reasonably designed, and the inner wall of the box has sufficient installation space to install 12 electricity meters at the same time to meet the metering needs of multiple users or multiple circuits. At the same time, 12 small circuit breakers are installed on the lower part of the inner wall of the box. These circuit breakers correspond one-to-one with the electricity meters and are used to protect and control the corresponding circuits. The electricity meters and circuit breakers are connected by 12 corresponding cables to achieve electricity metering and circuit on-off control.

[0004] The aforementioned meter box uses a method that secures the cables directly inside the box. Due to the large number of cables, workers can easily accidentally touch the cables during daily use or maintenance while operating other equipment, replacing components, or performing line maintenance. Improper force can pull, squeeze, or even cut the cable insulation, causing short circuits and leakage, leading to electric shock accidents and serious threats to workers' lives. This leaves room for improvement. Summary of the Invention

[0005] The purpose of this application is to provide a meter box with a hidden wiring function to solve the problem in the above-mentioned related technology that there are many cables and there may be safety hazards caused by accidental contact during subsequent use or maintenance.

[0006] The present application provides a meter box with hidden wiring function, which adopts the following technical solution: A metering box with a hidden wiring function comprises a box body and a box door mounted on the box body; a plurality of heat conduction ports are provided on two opposite vertical outer sides of the box body, and a deflector with the opening facing the outer edge of the heat conduction port is fixedly provided; an insulating plate is fixedly provided on two opposite vertical side surfaces of the box body, and a plurality of wiring holes are provided on the insulating plate; the side of the insulating plate facing the box door is a fixing surface for installing an electric meter and a circuit breaker, and an accommodating gap for placing cables is provided on the insulating plate and the inner wall of the box body away from the box door, and both ends of the cable pass through corresponding wiring holes and are respectively connected to the electric meter and the circuit breaker.

[0007] By adopting the above technical solution, the meter box is equipped with insulating plates on two opposite vertical sides of the box body. The insulating plates have wiring holes. The side facing the box door is the installation and fixing surface for the meter and circuit breaker. There is an accommodation gap between the inner wall of the box body away from the door. The two ends of the cable pass through the corresponding wiring holes and connect to the meter and circuit breaker respectively. This design hides the main body of the cable within the accommodation gap, greatly reducing the possibility of workers accidentally touching the cable, avoiding dangerous situations such as cable damage, short circuit, and leakage caused by accidental touching, significantly improving the safety performance during subsequent maintenance, and providing more reliable protection for power metering.

[0008] Optionally, a protective shell for protecting the circuit breaker is fixedly provided on the side of the insulating plate close to the box door, and an operating port for an operating handle on the circuit breaker to pass through is opened on the protective shell.

[0009] By adopting the above technical solution, the protective shell can provide a reliable physical protection barrier for the circuit breaker, effectively resisting adverse factors such as external collisions and accidental touches, and ensuring the safe and stable operation of the circuit breaker; at the same time, the setting of the operation port ensures that the staff can conveniently adjust the status of the circuit breaker through the operating handle when necessary, which not only achieves effective protection for the circuit breaker without affecting its normal operation, but also improves the overall reliability and safety of the meter box.

[0010] Optionally, a control port that coincides with the operating port is provided on the box door, and a baffle is provided on the outside of the box door to protect the control port, and the upper edge of the baffle is rotatably connected to the outer side surface of the box door.

[0011] By adopting this technical solution, the baffle provides physical protection for the control port, effectively blocking the ingress of dust and debris, preventing them from interfering with circuit breaker operation. It also prevents personnel from accidentally touching the operating handle, reducing the risk of misoperation. The rotating connection method allows personnel to operate the circuit breaker by simply turning the baffle upward to directly control the operating handle through the control port, making operation convenient and safe. This design balances protection and operational convenience, improving the overall safety performance and user experience of the meter box.

[0012] Optionally, a cleaning scraper is provided on the upper outer surface of the box body, and an adjusting rod is provided on the bottom outer surface of the box body; the sliding directions of the cleaning scraper and the adjusting rod are parallel, and a connecting piece is provided on the outside of the box body, and the adjusting rod can drive the cleaning scraper to slide back and forth through the connecting piece during the sliding process.

[0013] By adopting the above technical solution, when impurities accumulate on the top of the metering box, the staff only needs to operate the adjustment rod to slide at the bottom of the box, and then the cleaning scraper can be driven to slide back and forth on the top of the box through the connecting parts, so as to easily remove impurities without climbing high places for cleaning. This not only reduces the difficulty and danger of cleaning, but also can clean impurities in time, ensure the good performance of the box, ensure that the electronic components inside the metering box operate stably at an appropriate temperature, and extend their service life.

[0014] Optionally, the connecting part includes two traction ropes fixed relatively to the opposite sides of the adjusting rod, and the ends of the traction ropes away from the adjusting rod are wound around the top of the box in a vertical upward direction; the ends of the two traction ropes away from the adjusting rod are fixedly connected to the opposite sides of the cleaning scraper respectively; the upper and lower parts of the box relative to the two vertical sides are rotatably installed with guide pulleys, and the outer periphery of the guide pulley is provided with a guide groove for the traction rope to be inserted into.

[0015] By adopting the above technical solution, the traction rope and the guide pulley are coordinated, and the adjusting rod can smoothly and accurately drive the cleaning scraper to move back and forth when sliding, thereby ensuring the cleaning effect; the guide groove of the guide pulley effectively constrains the position of the traction rope to prevent it from deviating, thereby ensuring the stability of movement; and the structure is simple and reliable, easy to install and maintain, reducing the manufacturing cost and the difficulty of subsequent maintenance; at the same time, utilizing the flexible characteristics of the traction rope, it can adapt to the complex structure of the box body, realize the effective reciprocating motion of the cleaning scraper on the upper part of the box body, and improve the convenience and reliability of cleaning the top of the metering box.

[0016] Optionally, the adjusting rod is rotatably connected to a traction plate, and the traction plate can be rotated upward to a horizontal state abutting against the bottom side of the box body, and a locking member is provided on the bottom side of the box body to limit the abutment state of the traction plate.

[0017] By adopting the above technical solution, when there is no need to operate the adjusting rod for cleaning, the traction plate is rotated upward to a horizontal state and limited by the locking piece, which can effectively prevent the adjusting rod from sliding due to accidental touch, avoid malfunction of the cleaning scraper, and ensure the normal operation of the internal components of the metering box; when cleaning is required, the limit of the traction plate by the locking piece is released, and the traction plate is rotated to operate the adjusting rod, which is convenient to operate; at the same time, the structure of the traction plate is simple and practical, which increases the convenience and stability of the adjustment rod operation and reduces the potential risks caused by misoperation.

[0018] Optionally, a plurality of heat dissipation openings are provided on the bottom side of the box body, and a sealing opening that can overlap with the blocking opening is provided on the traction plate. The blocking opening can overlap or be misaligned with the heat dissipation opening when the traction plate is in a horizontal state and as the adjustment rod slides.

[0019] By adopting this technical solution, when the internal temperature of the meter box is low and no significant heat dissipation is required, the sliding adjustment rod offsets the blocking port and the heat dissipation port, and the pull plate blocks the heat dissipation port, effectively preventing the ingress of dust and debris and protecting the internal components. When the temperature rises and heat dissipation needs to be increased, the adjustment rod slides to align the blocking port with the heat dissipation port, opening the heat dissipation port and enhancing the heat dissipation effect. This dynamic adjustment method not only ensures the heat dissipation requirements of the meter box, but also reduces the risk of dust intrusion, improving the reliability and stability of the equipment.

[0020] Optionally, the locking member includes two locking rods slidably arranged on the bottom side of the box body, the two locking rods are located on opposite sides of the adjusting rod, the locking rods are parallel to the sliding direction of the adjusting rod, a locking plug is fixed to the side of the locking rod close to the adjusting rod, and a locking slot for inserting the locking plug is opened on the side of the traction plate away from the adjusting rod.

[0021] By adopting the above technical solution, when the traction plate is rotated to a horizontal state, the sliding locking rod allows the locking plug to be accurately inserted into the locking slot, thereby achieving reliable locking of the traction plate, effectively preventing it from being displaced due to vibration, accidental touch, etc., and ensuring the stability of the adjustment rod and the cleaning scraper; when the adjustment rod needs to be operated, the sliding locking rod allows the locking plug to be disengaged from the locking slot, which can be easily released and the operation is convenient; the overall structure is simple and reasonable, easy to install and maintain, and the overall safety and ease of use of the metering box are improved.

[0022] Optionally, a blocking plate that can slide up and down is provided on the vertical outer surface of the box body, and a blocking opening for the air deflector to pass through is provided on the blocking plate; an elastic extrusion part is provided on the outside of the box body to drive the blocking plate to move downward, and a control part is provided on the side of the two locking rods away from the adjusting rod to drive the blocking plate to move up to block the lower opening of the air deflector; the control part can drive the blocking plate to move up when the two locking rods slide back to back, and the lower opening of the air deflector is pressed against the lower inner wall of the blocking opening when the blocking plate moves up; the traction plate slides synchronously with the locking rod when the air deflector is blocked to a state where the blocking opening and the heat dissipation opening are misaligned.

[0023] By adopting this technical solution, when the air deflector needs to be sealed, the locking levers are operated to slide in opposite directions, and the control member drives the blocking plate upward, so that the lower opening of the air deflector is tightly abutted against the lower inner wall of the blocking port. This prevents dust and debris from entering the box through the air deflector, ensuring the safe and stable operation of the components inside the box. At the same time, when the air deflector is sealed, the traction plate slides synchronously with the locking lever to a state where the sealing port is offset from the heat dissipation port, further enhancing the sealing of the box and preventing the heat dissipation port from becoming a channel for dust and debris to enter when heat dissipation is not required.

[0024] Optionally, a plurality of moving wheels are fixed on one side of the traction plate, and a receiving groove for the moving wheels to be placed in and slide horizontally is opened on the bottom side of the box body; the sides of the traction plate away from the moving wheels and facing the moving wheels can both abut against the bottom side and remain fixed.

[0025] By adopting the above technical solution, when the metering box needs to be moved a short distance, the traction plate is placed away from the side of the moving wheel and abutted against and fixed to the bottom of the box body, and the box body can be easily moved by the traction plate; when ensuring long-distance transportation, the moving wheel is turned into the accommodating groove, and the traction plate is placed toward the side of the moving wheel and abutted against and fixed to the bottom side, thereby reducing the overall volume of the metering box and reducing costs.

[0026] In summary, this application has the following beneficial technical effects: When used, the meter box can hide the cable body in the accommodating gap, greatly reducing the possibility of workers accidentally touching the cables, avoiding dangerous situations such as cable damage, short circuit, leakage, etc. caused by accidental touch, significantly improving the safety performance in the subsequent maintenance process, and providing more reliable protection for power metering work.

[0044] The implementation principle of the embodiment of this application is: Cleaning state: After the outdoor high-rise metering box is installed, the locking piece 34 that locks the traction plate 33 can be released, and the lower end of the traction plate 33 can be held to drive the adjustment rod 32 to slide. By controlling the sliding of the adjustment rod 32, the connecting piece 35 (traction rope 351, guide pulley 352) drives the cleaning scraper 31 to slide back and forth, thereby cleaning impurities on the top of the box body 1; Mobile state: When the meter box needs to be moved a short distance, the side of the traction plate 33 away from the moving wheels 333 is abutted against the bottom side of the box body 1 and fixed. The traction plate 33 can be used to easily move the box body 1. When transporting over long distances, the moving wheels 333 are rotated into the receiving grooves 17, and the traction plate 33 is abutted against the bottom side of the side facing the moving wheels 333. This design can effectively reduce the overall volume of the meter box. The reduced volume can reduce space occupied during transportation. Heat dissipation state (during installation): The traction plate 33 is in a horizontally locked state, which does not affect the sliding of the traction plate 33 and the adjustment rod 32. At this time, the traction plate 33 slides with the adjustment rod 32, and the blocking port 331 coincides with the heat dissipation port 16, achieving normal heat dissipation; Blocked state (during installation and application): When the weather is bad outdoors, release the lock of the traction plate 33 by the locking part 34, slide the traction plate 33 to make the blocking port 331 and the heat dissipation port 16 misaligned, and at the same time, the locking rod 341 slides to drive the control part 43 to move the blocking plate 41 upward, and the lower opening of the air deflector 12 is pressed against the lower inner wall of the blocking port 411, thereby achieving double blocking of the heat dissipation port 16 and the lower opening of the air deflector 12, thereby improving safety performance.
