Description

Technical Field

[0001] This disclosure relates to the field of outdoor electricity meter box equipment technology, and in particular to a modular and expandable outdoor electricity meter box. Background Technology

[0002] Electricity meters are commonly used devices for measuring electricity. To ensure the secure installation and protection of electricity meters, they are often installed inside a meter box.

[0003] Patent application CN202410912995.2 discloses an outdoor smart meter box. It uses a humidity sensor to detect the moisture content in the air and transmits the data to a central processing unit. When the humidity sensor detects a value greater than a preset threshold, the central processing unit sends a command to a drive motor. The drive motor rotates a rotating shaft and gears, which in turn drive a rack to slide downwards, pulling down the connecting shaft and the end of the cover plate. The cover plate slides on a sliding block, and its lower end extends towards both sides of the meter box, making it horizontal and covering the upper end of the meter box. Simultaneously, an arc-shaped plate covers the connection point between the two covers, preventing rainwater from seeping into the meter box through this connection. Furthermore, the support rod and sliding block provide support for the cover plate, creating a gap between the cover plate and the upper end of the meter box, thus facilitating the movement of the meter. Heat inside the meter box dissipates outwards through the gap between the cover and the upper part of the meter box, ensuring efficient heat dissipation. Simultaneously, because the cover extends to the side of the meter box from the end connected to the connecting shaft, in windy conditions, rainwater is forced downwards and falls through the extended portion of the cover, preventing wind from blowing rainwater into the meter box. This not only improves the heat dissipation efficiency of the internal components but also prevents rainwater from entering the meter box. A baffle covering the side opening of the meter box further prevents rainwater from entering through this opening. Since the protective plate is located between the baffle and the dust filter, the desiccant absorbs moisture from the air inside the meter box during continuous rainy weather, preventing damage to the internal components due to excessive humidity. Patent application number CN202511234177.Patent 2 discloses a moisture-proof meter box. It uses temperature and humidity sensors to monitor the internal environment in real time. When the temperature and humidity are abnormal, it automatically activates the lifting mechanism and exhaust unit, achieving a fully integrated "air intake-dehumidification-exhaust" process. When the lifting mechanism drives the dehumidification box upwards, it simultaneously raises the rain cover, opening the ventilation slots to allow air in and releasing the seal of the exhaust unit. External air enters the box after being filtered and dehumidified by the dehumidification box. The exhaust fan accelerates the exhaust of hot and humid air, quickly reducing the internal temperature and humidity. After returning to normal, all components automatically reset and seal, avoiding the corrosion and insulation aging problems caused by moisture intrusion in traditional meter boxes. It balances moisture protection and heat dissipation, making it suitable for outdoor use in high-humidity, high-temperature environments. Sealing gaskets are installed on the box body, door, connecting frame, and rain cover to form a full-circumferential seal. The sealing seat of the moisture-proof mechanism fits snugly against the partition, and rubber protrusions block the ventilation slots. The sealing plug of the protective mechanism is embedded in the exhaust pipe. Multiple seals work together to prevent external moisture and rainwater from seeping in through gaps; the protective groove at the bottom of the rain cover wraps around the top of the enclosure, and the expansion slot matches the exhaust pipe, ensuring smooth exhaust while preventing rainwater from falling directly into the exhaust unit; the mechanical seal at the sliding joint between the support frame and the enclosure further reduces the risk of leakage through gaps, creating a reliable waterproof and moisture-proof barrier for the electrical components inside the enclosure. A lifting mechanism drives the dehumidifier box and rain cover to move synchronously, ensuring that the opening of the ventilation slot and the unsealing of the exhaust unit are synchronized, preventing moisture backflow caused by a single action; the sliding connection between the support frame and the dehumidifier box guides the rain cover to rise and fall smoothly, preventing component misalignment and jamming; the U-shaped design of the dehumidifier box expands the dehumidification area, and the filter plate works with the ventilation slot to ensure smooth air intake while intercepting dust and contaminating components; a spring provides stable power for the rain cover to reset, the sealing plug and exhaust pipe are precisely matched, and the movement trajectory of each component is controllable, reducing the likelihood of failure over long-term use and ensuring the stability and durability of the device.

[0004] According to its publicly available technical solutions, existing outdoor meter box equipment has several drawbacks. First, it cannot adjust the size of the meter box according to the number of meters to be installed and used, which can easily lead to insufficient capacity for the required number of meters or excessive remaining space, hindering space conservation. Second, it cannot effectively adjust the cooling fan speed based on the temperature inside the meter box, which can easily result in insufficient cooling leading to damage to the equipment inside the meter box, or excessive cooling speed leading to energy waste. Third, when adjusting the fan speed based on temperature, the mechanical adjustment structure is prone to vibration and fluctuations, which can cause excessively frequent changes in the fan's current and damage, compromising the fan's operational safety.

[0017] The technical solution provided in this disclosure may include the following beneficial effects: In use, depending on the number of meters to be installed and used, insert one or more side boxes' insert plates into the inner side of the right side frame of the main box. This causes the inner frame to first press against the beveled surface of the latch, then compress the latch spring and press it into the inside of the latch slot. Once the latch has moved to the inside of the latch slot, fully insert the insert plate into the inner side of the inner frame until the side box is secured to the right side of the main box by the sealing sleeve. At this point, the latch moves to the inside of the slot, and under the support of the spring and the support plate, the latch moves further into the slot, thus fixing the insert plate to the inside of the inner frame. Finally, the elasticity of the side plate causes it to pull the latch frame into the side box. The inner side of the inner frame is fully pressed into the inner side of the slot, or the side panel is directly clamped into the inner side of the slot in the inner frame of the main box using the slot. The main box is then used for independent installation and protection of the electricity meter, or the main box is used to carry one or more side boxes for installation and protection of the electricity meter. The electricity meter is installed on the bracket in the main box and side box with bolts. The observation port on the door panel allows personnel to easily observe the electricity meter data. The size of the box can be adjusted according to the number of electricity meters to avoid the problem of the electricity meter not fitting or the creation of empty space inside the box, thus saving the space of the box.

[0018] During operation, the fan draws hot air from the main and side chambers through the duct, causing air to flow inward through the grille and be filtered by the filter screen, thus ventilating and cooling the interior of the main and side chambers. The hot air in the main chamber heats the air inside the retainer, causing it to expand. This expanding air compresses the sliding plate inside the bottom sleeve downwards, pushing the lubricating oil through the fine holes to the inside of the sleeve. This pushes the piston to the left, pressing the button on the left side, which in turn turns on the motor. The motor, via a lead screw, drives the outer rod to move to the left under the limit of the guide rod. This, in turn, causes the outer rod to move the inner rod and sliding rod to the left until the inner rod, through the sliding rod, moves the button to the left and separates from the piston. At this point, the motor stops rotating, and the outer rod, through the locking mechanism, moves... The toothed grooves drive the knob to rotate on the speed controller, increasing the fan speed. Conversely, when the air inside the shroud contracts, the piston pushes the button on the right, causing the motor to rotate in the opposite direction. The toothed grooves then drive the knob to rotate in the opposite direction on the speed controller, decreasing the fan speed. This automatically adjusts the cooling airflow based on the heat generated in the main and side boxes. This prevents circuit malfunctions in the main and side boxes due to insufficient cooling, ensuring equipment safety, and also avoids excessive cooling airflow that wastes energy. Furthermore, regardless of whether or not side boxes are installed, or the number of side boxes, the fan can cool all the meters in the main and side boxes, ensuring equipment safety and reducing the number of fans required.

[0019] When the equipment is subjected to vibration, the outer rod and inner rod are supported and fixed by the guide rod and lead screw. The lead screw and guide rod are fixed to the inside of the main housing by the motor, so that the outer rod will not rotate due to vibration by driving the teeth through the locking groove. When the piston is subjected to vibration, the lubricating oil in the sliding sleeve needs to be pushed to the inside of the bottom sleeve or drawn from the inside of the bottom sleeve to the inside of the sliding sleeve. The slow flow of lubricating oil in the fine holes prevents the vibration direction from changing before the piston has made effective movement, thus effectively ensuring the stability of the piston and preventing the piston from pressing the button back and forth due to vibration. This effectively prevents the knob from being turned frequently and thus prevents the fan from being adjusted frequently, ensuring the safe operation of the fan.

The movable assembly includes a piston 20 and an inner rod 21. An electronic control assembly is installed on the inner rod 21. The electronic control assembly includes a sliding rod 24 and a button 25.The control assembly includes a motor 27 and a speed regulator 30, both of which are installed inside the main housing 1. A pushing assembly is mounted on the motor 27, comprising a lead screw 28 and a guide rod 29. A translation assembly is sleeved on the outer side of the lead screw 28, comprising an outer rod 26 and a locking thread 33. A rotating assembly is mounted on the speed regulator 30, comprising a knob 31 and a toothed thread 32. A bracket 35 is bolted to the inner sides of the main housing 1 and the side housing 2. Electricity meters 36 are bolted to the bracket 35 and are evenly distributed on it. The top of the retaining cover 17 is welded to the inner wall of the top of the main housing 1. A bottom sleeve 18 is welded to the bottom of the retaining cover 17, with its top connected to the bottom of the retaining cover 17. The outer side of the sliding plate 22 is secured to the inner wall of the bottom sleeve 18. The sliding sleeve 19... One end of the piston 20 is welded to the bottom of one side of the base sleeve 18. The fine hole 23 is opened at the bottom of one side of the base sleeve 18.

The speed regulator 30 is connected to the fan 16 through an electric wire.

[0024] Understandably, when the equipment is subjected to vibration, the outer rod 26 and the inner rod 21 are supported and fixed by the guide rod 29 and the lead screw 28. The lead screw 28 and the guide rod 29 are fixed to the inside of the main housing 1 by the motor 27, so that the outer rod 26 will not rotate due to vibration by driving the toothed groove 32 through the snap 33. When the piston 20 is subjected to vibration, the lubricating oil in the sliding sleeve 19 needs to be pushed to the inside of the bottom sleeve 18 or drawn from the inside of the bottom sleeve 18 to the inside of the sliding sleeve 19. By utilizing the slow flow of lubricating oil in the fine hole 23, the vibration direction is changed before the piston 20 has made effective movement, thereby effectively ensuring the stability of the piston 20 and preventing the piston 20 from pressing the button 25 back and forth due to vibration, thereby effectively preventing the knob 31 from being rotated frequently, thereby preventing the fan 16 from being adjusted frequently and ensuring the working safety of the fan 16.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, one side of the door panel 13 is hinged to the main box 1 and the side box 2 respectively, and the other side of the door panel 13 is fixed to the main box 1 and the side box 2 respectively by a lock body. The observation port 14 is installed on the inner side of the door panel 13. The fan 16 is bolted to the inner side of the air duct 15. The main box 1 is connected to the outer side of the main box 1 through the air duct 15. The inner frame 6 is integrally formed on the inner wall of the other side of the main box 1 and the side box 2. The slot 7 is opened on the inner side of the inner frame 6. The insert plate 8 is integrally formed on one side of the side box 2. The outer side of the insert plate 8 on the side box 2 is clamped to the inner wall of the inner frame 6 inside the main box 1. The width of the insert plate 8 is equal to the width of the inner frame 6. One side of the side box 2 is sealed and clamped to the other side of the main box 1 by a sealing strip. On one side, the bayonet 9 is opened on the inner side of the insert plate 8. The bayonet 9 is evenly distributed on the insert plate 8. The inner side of the bayonet 9 is integrally formed with a support plate 11. The outer side of one end of the locking pin 10 is locked on the inner wall of the bayonet 9. The other end of the locking pin 10 passes through the bayonet 9 and extends to the inner side of the slot 7. One end of the locking pin 10 is connected to the support plate 11 by a spring 12.

The side box 2 is connected to the outside of the side box 2 through the grille 4. The inner sides of the air duct 15 and the grille 4 are both bolted with filter screens.

[0026] Understandably, during use, depending on the number of meters 36 to be installed and used, one or more insert plates 8 on the side box 2 are inserted into the inner side of the inner frame 6 on the right side of the main box 1. This causes the inner frame 6 to first press the inclined surface on the latch 10, then compress the latch 10 to the spring 12 and press it into the inner side of the latch 9. After the latch 10 moves to the inner side of the latch 9, the insert plate 8 is fully inserted into the inner side of the inner frame 6 until the side box 2 is secured to the right side of the main box 1 by the sealing sleeve. At this time, the latch 10 moves to the inner side of the slot 7. The latch 10 moves into the slot 7 under the support of the support plate 11 by the spring 12, thereby fixing the insert plate 8 to the inner side of the inner frame 6. Then, using the elasticity of the side plate 3, the side plate 3 drives the latch frame 5 to insert. The meter 36 is inserted into the inner frame 6 of the side box 2, and the clip frame 5 on the side plate 3 is fully pressed into the inner side of the slot 7, or the side plate 3 is directly clamped into the inner side of the slot 7 in the inner frame 6 of the main box 1 through the clip frame 5. Then the main box 1 is used for independent installation and protection of the meter 36, or the main box 1 is used to carry one or more side boxes 2 for installation and protection of the meter 36. The meter 36 is installed on the bracket 35 in the main box 1 and the side box 2 by bolts. The observation port 14 on the door panel 13 allows personnel to observe the electricity meter data of the meter 36. The size of the box can be adjusted according to the number of meters 36 to avoid the meter 36 not fitting or the empty space inside the box, thus saving the space of the box.

[0027] like Figure 4 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, the partition 34 is bolted to the inner wall of the other end of the sliding sleeve 19. One end of the inner rod 21 is located inside the sliding sleeve 19, and the other end of the inner rod 21 passes through the partition 34 and extends to the outside of the sliding sleeve 19. The inner rod 21 is located on one side of the piston 20. One end of the sliding rod 24 is welded to one end of the inner rod 21, and the other end of the sliding rod 24 passes through the piston 20 and extends to the other side of the piston 20. The buttons 25 are respectively installed on the top of both ends of the sliding rod 24. The buttons 25 are symmetrically distributed on both sides of the piston 20. A connecting rod is bolted to the top of the motor 27. The top end of the outer rod 26 is bolted to the inner wall of the top of the main box 1. One end of the outer rod 26 is welded to the other end of the inner rod 21. One end of the lead screw 28 is keyed to the output shaft of the motor 27. The inner side of the outer rod 26 has a threaded opening with an internal thread. The outer side of the lead screw 28 has an external thread, and the internal thread and external thread cooperate. The other end of the outer rod 26 is sleeved on the outer side of the lead screw 28 through the threaded opening. One end of the guide rod 29 is bolted to the motor 27. The inner side of the outer rod 26 has a guide groove, and the guide groove is sleeved on the outer side of the other end of the guide rod 29.

[0028] Understandably, during operation, the fan 16 draws hot air from the main chamber 1 and side chamber 2 through the air duct 15, causing air to flow into the side chamber 2 through the grille 4. After being filtered by the filter, the air ventilates and cools the inside of the side chamber 2 and the main chamber 1. The hot air in the main chamber 1 heats the air inside the cover 17, causing it to expand. The expanding air exerts downward pressure on the slide plate 22 inside the bottom sleeve 18. The slide plate 22 slowly pushes the lubricating oil through the fine hole 23 to the inside of the sliding sleeve 19, which in turn pushes the piston 20 to the left. The piston 20 presses the button 25 on the left side, thereby turning on the motor 27. The motor 27 drives the outer rod 26 to move to the left under the limit of the guide rod 29 via the lead screw 28. This causes the outer rod 26 to drive the inner rod 21 and the slide rod 24 to move to the left until the inner rod 21, through the slide rod 24, moves the button 25 to the left and separates from the piston 20. At this point, the motor 27 stops rotating. Meanwhile, the outer rod 26 drives the toothed groove 32 through the locking groove 33, which in turn drives the knob 31 to rotate on the speed regulator 30, so as to increase the speed of the fan 16. Conversely, when the air in the cover 17 contracts, the piston 20 presses the button 25 on the right side to the right, the motor 27 rotates in the opposite direction, the locking groove 33 drives the knob 31 to rotate in the opposite direction on the speed regulator 30 through the toothed groove 32, so as to decrease the speed of the fan 16. It can automatically adjust the cooling air force according to the heat generated in the main box 1 and the side box 2. It can not only avoid the circuit failure in the main box 1 and the side box 2 due to insufficient heat dissipation, thus ensuring the safe operation of the equipment, but also avoid the waste of electricity due to excessive cooling air force. At the same time, regardless of whether the side box 2 is installed or the number of side boxes 2 is different, the fan 16 can cool down all the electric meters 36 in the main box 1 and the side box 2, ensuring the safe operation of the equipment, and saving the number of fans 16 used.
