Description

Technical Field

[0001] This invention relates to the field of electricity prepaid meter box technology, specifically a multi-protection anti-interference electricity prepaid meter box. Background Technology

[0002] Electricity prepaid meter boxes, as key equipment for electricity metering, cost control, and power management in power supply systems, are widely used in residential communities, commercial buildings, industrial plants, and other locations. With the development of intelligent and automated power systems, higher requirements are being placed on the stability, reliability, and security of electricity prepaid meter boxes. However, existing electricity prepaid meter boxes have many problems in practical applications, making it difficult to meet the needs of complex environments and high-standard power management.

[0003] In terms of waterproofing, dustproofing, and environmental adaptability, existing meter boxes have poor sealing performance and inadequate ventilation protection measures. In rainy or snowy weather, dusty environments, or industrial sites with high dust levels, rainwater, dust, and insects can easily enter the box. Rainwater may cause short circuits, dust accumulation may affect component heat dissipation, and insects may damage the wiring. These factors seriously threaten the normal operation of the electrical components inside the meter box, leading to increased equipment failure rates and shortened service life.

[0004] In terms of power measurement and control and accurate metering, most traditional power meter boxes have limited functionality in their power measurement and control modules, resulting in low data acquisition accuracy and a lack of real-time monitoring and intelligent control capabilities. They cannot promptly detect abnormalities such as overloads and leakage in circuits, and cannot take effective protective measures in the early stages of faults, easily leading to safety accidents. Furthermore, their metering errors are relatively large, failing to meet the power system's requirements for accurate metering and causing inconvenience to power management.

[0005] Therefore, it is urgent to develop a multi-protected and anti-interference power fee control meter box to solve the problems in the existing technology and meet the growing needs of the power system. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] In existing technologies, the seismic-resistant structure of power meter boxes mostly uses simple brackets for fixation. Under environments such as earthquakes and mechanical vibrations, it is difficult to effectively resist shaking, which can easily lead to loosening of internal components, disconnection of connecting lines, or even the entire meter box tipping over, affecting the accuracy of power metering and the service life of the equipment. In contrast, the multi-protection anti-interference power meter box of this invention constructs a stable foundation support through the tight connection of the seismic-resistant columns and anti-loosening mounting plates and bolts in the seismic-resistant and anti-sway assembly mechanism. Combined with the three-dimensional stable structure composed of adaptive scissor forks, triangular support reinforcement rods, and vibration-resistant toughness connecting rods, it can evenly distribute shaking stress. At the same time, the screw and flexible buffer contact block further buffer the impact. This design allows the meter box to remain stable even in complex vibration environments. Compared with existing technologies, it greatly reduces the probability of equipment failure caused by vibration, effectively ensures the stability and reliability of power metering and control equipment, and extends the service life of the equipment.

[0018] Traditional power meter boxes have shortcomings in waterproof and dustproof design, with poor sealing performance and ineffective protection of ventilation openings. This allows dust, rainwater, and insects to easily enter the box, causing problems such as short circuits and component corrosion. Especially in harsh weather or dusty environments, the equipment failure rate is high. The fully enclosed electrical control cabinet of this invention forms a tight seal through a waterproof and dustproof sealed door, an explosion-proof viewing window, and anti-pry locks. Combined with the heat dissipation and ventilation protection plate at the front end of the ventilation slot and the foreign object and insect-proof filter at the rear end, it achieves comprehensive waterproof, dustproof, foreign object intrusion prevention, and vandal prevention functions while ensuring efficient heat dissipation. Compared with existing technologies, this meter box can adapt to various harsh environments such as rain, snow, and sandstorms, significantly improving the operational stability of the equipment in complex environments and reducing maintenance costs and equipment damage risks caused by environmental factors.

[0019] Existing power meter boxes have limited functionality in their power measurement and control modules, resulting in low data acquisition accuracy and a lack of real-time monitoring and intelligent control. This makes them unable to promptly detect and handle circuit anomalies, easily leading to metering errors and safety hazards. The power measurement and control integrated module of this invention integrates a main control unit, an energy meter, a safety switch, and a real-time leakage current monitoring module. The main control unit can accurately collect and analyze power data in real time, enabling intelligent management of the power system. The real-time leakage current monitoring module can monitor leakage in real time and provide timely feedback, working in conjunction with the safety switch to quickly cut off the power supply. Compared to existing technologies, this meter box achieves high-precision metering, real-time monitoring, and intelligent control in power measurement and control, effectively improving the accuracy of power metering and the security of power supply, reducing the possibility of safety accidents caused by circuit faults, and providing more reliable technical support for power management.

[0026] 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.

[0027] Please see Figures 1-5As shown, the present invention provides a technical solution: a multi-protection anti-interference power meter box, comprising an anti-vibration and anti-sway assembly mechanism 1 and a fully enclosed electrical control cabinet 2. The anti-vibration and anti-sway assembly mechanism 1, through components such as anti-vibration columns 11 and anti-loosening mounting plates 12, in conjunction with adaptive scissor forks 13, vibration-resistant toughness connecting rods 18 and triangular support reinforcement rods 19, achieves stable anti-vibration and anti-sway. The fully enclosed electrical control cabinet 2 integrates a power measurement and control integrated module 3, a drying mechanism 4, a safety protection alarm device 7, and a circulating water cooling and protection component 6. The power measurement and control integrated module 3 includes a main control unit 31, an energy meter 32, etc., which can accurately measure and control power. The drying mechanism 4 utilizes temperature regulation... The dehumidification box 41 and fan 42 maintain internal dryness; in case of abnormality, the safety protection alarm device 7 activates the high-brightness flashing warning light 73 and the high-decibel voice broadcast speaker 74 via the emergency braking unit 71 to sound an alarm; the circulating water cooling protection component 6 collects rainwater with the help of the inclined rainproof guide plate 51, and drives it through the micro circulating water pump 65 to achieve circulating heat dissipation through the surrounding water cooling heat dissipation pipe 66. In addition, the waterproof and dustproof sealed door 21 and heat dissipation ventilation protection plate 24 of the fully enclosed electrical control cabinet 2 further enhance the waterproof, dustproof, explosion-proof and heat dissipation functions, effectively ensuring the stability and reliability of power metering and control, and meeting the needs of use in complex environments.

[0028] according to Figure 1 and Figure 2 As shown, the anti-seismic and anti-sway assembly mechanism 1 is a stable structure for the multi-protection and anti-interference power fee control meter box. It consists of basic components such as anti-seismic columns 11, anti-loosening mounting plates 12, support plates 14, screws 15, hexagonal toothed grooves 16, and flexible buffer contact blocks 17, as well as adaptive scissor forks 13, vibration-resistant toughness connecting rods 18, and triangular support reinforcement rods 19. The anti-loosening mounting plates 12 are connected to the outer sides of the two anti-seismic columns 11, and the mounting holes on the plates are used with bolts to achieve a stable installation. The front end of the anti-seismic column 11 is connected to the support plate 14, and one end of the screw 15 in its groove extends outward and is provided with hexagonal teeth. The groove 16 and the screw 15 are threaded together with a flexible buffer abutment block 17 at the outer end. The inner rubber pad can buffer external forces. In addition, the inner sides of the two anti-seismic columns 11 are connected to the adaptive scissor fork 13. The upper end is hinged to the triangular support reinforcement rod 19 and connected to the support plate 14. The lower end of the front end of the support plate 14 is connected to the lower front end of the anti-seismic column 11 through the anti-vibration toughness connecting rod 18. All components cooperate with each other to form a three-dimensional stable structure, which effectively absorbs and disperses external vibration and shaking, ensures the stable operation of the power fee control meter box in complex environments, and provides a reliable support foundation for other functional components in the meter box.

[0029] according to Figure 1 and Figure 3As shown, the fully enclosed electrical control cabinet 2 is the core load-bearing structure of the multi-protection anti-interference power fee control meter box. It has ventilation slots on both sides of its outer end, a heat dissipation and ventilation protection plate 24 at the front end, and a foreign object and insect-proof filter 25 at the rear end to achieve efficient heat dissipation and protection. The front end is connected to a waterproof and dustproof sealed door 21, equipped with an explosion-proof viewing window 22 and anti-pry lock 23 to ensure internal security. The rear end of the cabinet has a heat-conducting sealed chamber for installing components such as the power measurement and control integrated module 3. The upper end has an integrated drying mechanism 4 for dehumidification and moisture prevention, the lower end is equipped with a safety protection alarm device 7, the rear end is equipped with a circulating water cooling and protection component 6, and the top is fixed with a triangular support frame 5. The fully enclosed electrical control cabinet 2 provides all-round protection for the internal components of the meter box through multi-structure collaboration, ensuring the stable operation of power measurement and control and metering work.

[0030] Furthermore, the power measurement and control integrated module 3 is the core unit for achieving accurate power monitoring and control in the multi-protection anti-interference power fee control meter box. It is installed on the heat-conducting and sealed outer wall of the rear end of the fully enclosed power control cabinet 2. This module consists of a main control unit 31, an energy meter 32, a safety switch 33, and a leakage current real-time monitoring module 34. The main control unit 31 and the energy meter 32 are set in parallel, with the safety switch 33 connected to their lower ends. The leakage current real-time monitoring module 34 is configured on one side of their outer ends. The main control unit 31 manages the power data in a unified manner, the energy meter 32 accurately measures the power consumption, the safety switch 33 ensures the safe switching of the circuit, and the leakage current real-time monitoring module 34 monitors the leakage situation in real time. All components work together to provide reliable support for power metering and control.

[0031] Furthermore, the triangular support frame 5 plays a crucial supporting role in the multi-protection anti-interference power fee control meter box. Its lower end is firmly connected to the upper surface of the fully enclosed electrical control cabinet 2, and the upper end is equipped with an inclined rainproof and drainage rain shield 51. Through the stable triangular structure design, the triangular support frame 5 enhances the load-bearing capacity and stability of the top of the meter box. At the same time, in conjunction with the inclined rainproof and drainage rain shield 51, it effectively guides rainwater to the water collection boxes 61 on both sides, providing a water source for the circulating water cooling and protection components 6.

[0032] according to Figure 1 and Figure 4As shown, the drying mechanism 4 is the core component of the multi-protection anti-interference power control meter box to maintain a dry internal environment. It is fixedly installed on the upper surface of the fully enclosed electrical control cabinet 2. This mechanism consists of a temperature-regulating dehumidification box 41, a fan 42, an air intake connection pipe 43, and a precision filter 44. The temperature-regulating dehumidification box 41 absorbs moisture and can adjust the working temperature to adapt to different environmental needs. The fans 42 on both sides of the lower end provide airflow power to accelerate air circulation. The air intake connection pipes 43 on both sides of the outer end pass through the cabinet and connect to the outside. The precision filter 44 at the air intake end effectively filters dust and other impurities to ensure that the incoming air is clean. It continuously draws in humid air, dries it, and then discharges it, preventing electrical components from being damaged by moisture due to water vapor condensation inside the meter box. This creates a suitable environment for the stable operation of equipment such as the power measurement and control integrated module 3.

[0033] Furthermore, the safety protection alarm device 7 is a key system for ensuring the safe operation of the power fee control meter box with multiple protections and anti-interference capabilities. It is installed on the lower surface of the fully enclosed electrical control cabinet 2. The device is based on the emergency braking unit 71, whose output end extends to the lower outer end of the meter box through the anti-vibration and anti-sway assembly mechanism 1, and is connected to the high-brightness flashing warning light 73. A transparent protective cover 72 is installed on the outside, and a high-decibel voice broadcast speaker 74 is installed on one side. When abnormal conditions such as circuit overload or leakage are detected, the emergency braking unit 71 responds quickly, triggering the high-brightness flashing warning light 73 to emit a strong flashing light. At the same time, the high-decibel voice broadcast speaker 74 issues a voice alarm to warn the surrounding personnel to pay attention to safety. The transparent protective cover 72 effectively protects the warning light from external damage. Through rapid response, multi-form warnings and emergency braking, the safety protection alarm device 7 can eliminate safety hazards in a timely manner, avoid accidents, and comprehensively protect the safety of the power fee control meter box and its surrounding environment.

[0034] according to Figure 1 and Figure 5 As shown, the circulating water cooling and protection component 6 is a multi-protection anti-interference power fee control meter box system that achieves efficient heat dissipation. It is installed in the heat-conducting sealed chamber at the rear end of the fully enclosed electrical control cabinet 2 and on the top outside. The component uses the inclined rainproof guide rain shield 51 as the water source collection end, and the lower two sides are connected to the water collection box 61. The upper part of the interior is equipped with a dustproof and scale-inhibiting filter screen 62 to filter rainwater impurities. The lower rear end of the fully enclosed electrical control cabinet 2 is connected to the water storage box 64, which is connected to the water collection box 61 through the water supply pipe 63. The micro circulating water pump 65 in the water storage box 64 drives the water flow, which is coiled in an S-shape in the heat-conducting sealed chamber through the surrounding water cooling heat dissipation pipe 66. After absorbing the operating heat of the power measurement and control integrated module 3 and other components, the water flows back to the water storage box 64, forming a closed-loop heat dissipation circuit. The S-shaped pipe layout increases the heat dissipation area and ensures the stability of the meter box under high load operating environment.

[0035] The overall effect achieved by the organization is as follows:

[0036] Earthquake resistance and sway prevention, structural stability and protection

[0037] Two seismic-resistant columns 11 are firmly fixed in their installation positions by the anti-loosening mounting plates 12 and bolts, resisting foundation displacement. The screws 15 on the support plate 14, together with the flexible buffer abutment blocks 17, can effectively buffer the impact force and reduce vibration transmission when subjected to impact. The adaptive scissor fork 13 can adapt to deformation during shaking, distributing stress evenly to various components. The triangular structure formed by the triangular support reinforcement rod 19 and the vibration-resistant toughness connecting rod 18 uses the stability principle of triangles to disperse and transmit the force generated by shaking, preventing precision components such as the internal power measurement and control integrated module 3 from loosening or being damaged due to shaking, ensuring that the meter box remains stable in complex environments, and achieving the structural protection function of seismic resistance and anti-sway.

[0038] Waterproof, dustproof and environmentally adaptable protection

[0039] The fully enclosed electrical control cabinet 2 features a heat dissipation and ventilation protection plate 24 at the front end of the ventilation slots on both sides, which works in conjunction with the foreign object and insect-proof filter 25 at the rear end. This ensures internal air circulation and efficient heat dissipation while effectively preventing dust, foreign objects, and insects from entering the cabinet, thus preventing circuit failures caused by the accumulation of foreign objects. The waterproof and dustproof sealed door 21, together with the explosion-proof viewing window 22 and the anti-pry lock 23, forms a tight sealed protective structure. This not only prevents rainwater and moisture from entering but also resists external violent damage, creating a safe and stable operating environment for the internal components. This ensures that the meter box can still work normally in harsh weather conditions such as rain, snow, and sandstorms, achieving environmental protection functions such as waterproofing, dustproofing, and damage prevention.

[0040] Power measurement and control and precision metering control

[0041] The main control unit 31 collects the electricity data measured by the electricity meter 32 in real time, analyzes and processes the data, and manages the entire power system in a coordinated manner to ensure the accuracy and stability of electricity metering. The safety switch 33 is responsible for controlling the on / off state of the circuit. In the event of circuit maintenance or failure, it can quickly cut off the power supply to ensure the safety of personnel and equipment. The real-time leakage current monitoring module 34 continuously monitors the leakage current in the circuit. Once an abnormal leakage current is detected, it immediately feeds the signal back to the main control unit 31, which then takes protective measures such as power-off to prevent leakage current from causing safety accidents.

[0042] Drying, dehumidification and moisture protection

[0043] The fan 42 provides strong airflow, accelerating air circulation and allowing humid air to quickly flow through the temperature-regulating dehumidification box 41 for drying. The intake connection pipe 43 connects the inside of the cabinet to the outside, and the precision filter 44 at the intake end effectively filters out dust and other impurities in the air, ensuring that the air entering the cabinet is clean and dry. By continuously drawing in, drying, and expelling humid air, the drying mechanism 4 can prevent internal electrical components from being damaged by moisture, such as short circuits or oxidation, creating a suitable humidity environment for the stable operation of equipment such as the power measurement and control integrated module 3.

[0044] Safety alarms and emergency response protection

[0045] When abnormal conditions such as circuit overload, leakage, or short circuit are detected, the emergency braking unit 71 responds quickly. Through the anti-vibration and anti-sway assembly mechanism 1, it transmits a signal and triggers the high-brightness flashing warning light 73 to flash brightly. Simultaneously, the high-decibel voice broadcast speaker 74 provides a clear voice alarm, promptly alerting nearby personnel to safety and enabling them to take appropriate emergency measures. The transparent protective cover 72 protects the high-brightness flashing warning light 73 from damage in emergencies, ensuring the alarm device functions properly and providing comprehensive safety protection for the meter box and its surrounding environment, effectively preventing accidents.

[0046] Circulating heat dissipation and temperature control

[0047] The tilted rainproof and deflecting rain shield 51 serves as a water collection end, effectively collecting rainwater. After impurities are filtered out by the dustproof and scale-inhibiting filter 62 inside the water collection box 61, the rainwater flows into the water storage box 64 through the water pipe 63. The miniature circulating water pump 65 inside the water storage box 64 pumps the water out, driving the water flow into the surrounding water-cooled heat dissipation pipe 66. This pipe is S-shaped and coiled in the heat-conducting sealed chamber, greatly increasing the contact area with heat-generating components such as the power measurement and control integrated module 3, thereby efficiently absorbing the heat generated by the components during operation. The heat-absorbing water flows back to the water storage box 64, forming a closed-loop circulating heat dissipation circuit, continuously carrying away the heat inside the cabinet, effectively reducing the internal temperature of the cabinet, and ensuring that the internal components of the meter box remain within a suitable operating temperature range under high load conditions, maintaining the stable operation of the meter box.

[0048] Anti-interference coordination mechanism

[0049] The anti-vibration and anti-sway assembly mechanism 1 reduces the impact of external vibration interference on internal components; the fully enclosed electrical control cabinet 2's sealing structure and electromagnetic shielding design can resist external electromagnetic interference and protect the data acquisition and processing accuracy of the power measurement and control integrated module 3; the drying mechanism 4 and the circulating water cooling and protection component 6 maintain a stable temperature and humidity environment, avoiding performance degradation or malfunction of electronic components due to environmental fluctuations. All components work together to ensure that the meter box can still accurately measure electricity and operate stably under complex electromagnetic environments and harsh weather conditions.

[0050] 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.
