Description

Technical Field

[0001] This invention relates to the field of metering box technology, and in particular to a self-adjusting pressure interference fit metering box. Background Technology

[0002] Electricity metering boxes are used in outdoor or semi-outdoor settings. They integrate key electrical components such as self-adjusting interference sockets, meters, TMY copper busbars, and BVR wires. In rainy weather, rainwater can seep directly into the box through the ventilation slots on the side of the box. At the same time, in high humidity environments, moisture in the air will condense on the inner wall of the metering box and the surface of electrical components, forming condensation. Especially on rainy days or during periods of high humidity after rain, the accumulation of moisture directly affects the stability of the electrical connections inside the metering box.

[0003] The electrical components inside the electricity metering box, such as the self-regulating interference socket, meter, and TMY copper busbar, continuously generate heat during operation. Rainwater seeping in through the ventilation slots during rainy days, as well as condensation in high humidity environments, create a continuously accumulating humid environment inside the box. Under the influence of internal heat, this forms a hot and humid airflow that continuously adheres to the surfaces of internal components. When the meter circuit board comes into contact with moisture, its insulation performance deteriorates, making it prone to signal interference, data measurement deviations, and in severe cases, short circuits. In a hot and humid environment, the TMY copper busbar and BVR wire joints will oxidize and corrode more rapidly, forming a rust layer with poor conductivity, leading to increased contact resistance. This not only increases line losses but also causes abnormal temperature rise at the joints. The contact surface of the self-regulating interference socket will also corrode and wear due to moisture immersion, affecting the stability of its interference fit. Over the long term, this will comprehensively reduce the operational reliability of the metering box.

[0004] Currently, the ventilation slots on the metering box are only a single through-type design. In rainy weather, they cannot effectively prevent rainwater from seeping into the box through the gaps in the slots. At the same time, they cannot timely discharge the hot and humid air generated by the heating of the internal components. In rainy weather, hot and humid air easily accumulates inside the box. With long-term use, the components will become damp and age, leading to malfunctions and reducing the service life of the internal components. Summary of the Invention

[0005] The purpose of this invention is to provide a self-adjusting interference fit metering box, which solves the problems of not being able to effectively prevent rainwater from seeping into the box through the gaps in the tank during rainy weather, and not being able to timely discharge the hot and humid air generated by the heating of the internal components. In rainy weather, hot and humid air easily accumulates inside the box, and long-term use will cause the components to become damp and age, leading to failure and reducing the service life of the internal components.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: It includes a housing, the housing being divided into a first chamber for placing the adsorption assembly and a second chamber for arranging electrical components. A through-ventilation slot is provided on the side wall of the second chamber. A ventilation hole is provided in the partition between the first and second chambers. A driving assembly is installed inside the housing, used to synchronously drive the movement of a first baffle and a second baffle. The driving assembly includes a double-headed cylinder and a rotating shaft. The output end of the double-headed cylinder is fixedly connected to a first rack via a first moving plate. A first gear and a second gear are fixedly connected to the side surface of the rotating shaft. A second rack is meshed with the side surface of the second gear. A first baffle is fixedly connected to the upper end of the second rack via a second moving plate. A second baffle is fixedly connected to the upper surface of the first moving plate via a connecting block. A placement basket is provided inside the first chamber, and an adsorption pack is placed inside the placement basket.

[0007] Preferably, the side surface of the first gear meshes with the first rack, the side surface of the first baffle slides with the inner wall of the second chamber, and the first baffle is correspondingly provided with the ventilation slot, the second baffle slides with the top inner wall of the first chamber, and the second baffle is correspondingly provided with the vent.

[0008] Preferably, the left inner wall and the right inner wall of the first chamber are both fixedly connected to a first fixing rod, the first fixing rod is provided with a first sliding groove, the inner surface of the first sliding groove is slidably connected to a first slider, and the end of the first slider away from the box body is fixedly connected to a second rack.

[0009] Preferably, the left and right inner walls of the second chamber are both fixedly connected to a second fixing rod, the inside of the second fixing rod is provided with a second sliding groove, the inner surface of the second sliding groove is slidably connected to a second slider, and the end of the second slider away from the box body is fixedly connected to a second moving plate.

[0010] Preferably, a third fixing rod is fixedly connected to the top inner wall of the first chamber, a third sliding groove is provided inside the third fixing rod, a third slider is slidably connected to the inner surface of the third sliding groove, and the end of the third slider away from the third fixing rod is fixedly connected to the first moving plate.

[0011] Preferably, the interior of the housing is provided with a mounting bracket, and the front surface of the mounting bracket is provided with a self-adjusting interference socket.

[0012] Preferably, a third baffle is fixedly connected to the top inner wall of the first chamber, a temperature sensor and a humidity sensor are fixedly connected to the left inner wall of the second chamber, a rainwater detection sensor is fixedly connected to the upper surface of the box, and a controller is fixedly connected to the front surface of the mounting bracket.

[0013] Preferably, the box body is hinged with a first sealing door and a second sealing door, and the box body is provided with a sealing groove.

[0014] Preferably, the exterior of the housing is fixedly connected with heat dissipation fins.

[0015] Preferably, the vent connects the first chamber and the second chamber, and the adsorption bag is connected to the internal space of the second chamber through the vent to adsorb hot and humid air in the second chamber.

[0016] In summary, the present invention has at least one of the following beneficial technical effects:

[0017] 1. The present invention, by setting up a box body, a drive assembly, a first baffle, a second baffle and ventilation holes, allows the first baffle to move to the corresponding position of the ventilation slot in rainy weather, covering the through ventilation slots on both sides of the box body. The first baffle and the ventilation slot form a sealed protection, which can effectively prevent rainwater from entering the box body through the gaps in the slot, cut off the rainwater seepage path, and protect the internal electrical components from rainwater corrosion.

[0018] 2. In this invention, while the driving component moves the first baffle to block the ventilation slot, the second baffle moves simultaneously, opening the originally closed ventilation hole. The adsorption pack inside the box can come into contact with the hot and humid air inside the box, which can quickly contact the hot and humid air generated by the heating of the internal components. The moisture is locked in the adsorption medium, preventing the hot and humid air from accumulating and condensing in the closed box. This prevents the instruments, copper busbars, self-adjusting interference sockets and other components from aging, short circuits or poor contact due to moisture, thereby improving the service life of the internal components.

[0019] 3. The two actions of the first baffle blocking the ventilation groove and the second baffle opening the ventilation hole are synchronized by the same drive component, eliminating the need for two additional independent drive structures. This structure reduces the number of drive components, lowers the complexity of the internal structure of the housing, and reduces the space occupied by the components inside the housing.

[0031] The following is in conjunction with the appendix Figure 1 -Appendix Figure 10 The present invention will be further described in detail below.

[0032] This invention provides a self-adjusting interference fit connector metering box, including a box body 1. The box body 1 is divided into a first chamber 2 for placing an adsorption assembly and a second chamber 3 for arranging electrical components. The side wall of the second chamber 3 is provided with a through ventilation slot 15. The partition between the first chamber 2 and the second chamber 3 is provided with a vent hole 16, which connects the first chamber 2 and the second chamber 3. The adsorption pack 8 is connected to the internal space of the second chamber 3 through the vent hole 16, and is used to adsorb hot and humid air in the second chamber 3.

[0033] The electricity metering box in this application addresses the heat and humidity protection issues of traditional equipment by employing a partitioned design to optimize the internal space layout. The box body 1 serves as the load-bearing base for the entire device, providing installation support and external protection for all internal components. The box body 1 is divided into a first chamber 2 for housing the adsorption assembly. The first chamber 2 houses the adsorption pack 8 and also serves to physically isolate it from electrical components, preventing the adsorption material from interfering with the internal circuitry of the second chamber 3. The second chamber 3 is the core working area, centrally housing key electrical components such as meters and self-adjusting interference sockets 19. The side wall of chamber 3 is provided with a through ventilation slot 15, which is used to realize the air circulation inside and outside the box when it is not raining, and to assist the heat dissipation of internal components. The first chamber 2 and the second chamber 3 are connected by a vent 16. The vent 16 serves as a gas exchange channel between the two chambers, providing a path for hot and humid airflow to enter the adsorption area. The vent 16 connects the first chamber 2 and the second chamber 3. The adsorption bag 8 is connected to the internal space of the second chamber 3 through the vent 16, and is used to adsorb hot and humid air in the second chamber 3. By utilizing the hygroscopic properties of the adsorption medium, it actively captures water vapor in the air and reduces the humidity in the second chamber 3.

[0034] The housing 1 is equipped with a drive assembly 4, which is used to synchronously drive the first baffle 5 and the second baffle 6 to move. The drive assembly 4 includes a double-headed cylinder 401 and a rotating shaft 405. The output end of the double-headed cylinder 401 is fixedly connected to a first rack 403 through a first moving plate 402. A first gear 404 and a second gear 406 are fixedly connected to the side surface of the rotating shaft 405. A second rack 407 is meshed with the side surface of the second gear 406. The upper end of the second rack 407 is fixedly connected to the first baffle 5 through a second moving plate 408. The upper surface of the first moving plate 402 is fixedly connected to the second baffle 6 through a connecting block 24. The side surface of the first gear 404 is meshed with the first rack 403.

[0035] Drive component 4 is used to synchronously drive the first baffle 5 and the second baffle 6 to move. This synchronous linkage is driven by the same double-headed cylinder 401. The same drive structure can effectively reduce the number of drive components. The double-headed cylinder 401 is used to provide linear power output. Its bidirectional telescopic characteristic can drive the movement of two sets of transmission structures at the same time. The rotating shaft 405 is the intermediate carrier for power transmission and is used to realize the conversion of power direction. The output end of the double-headed cylinder 401 realizes the synchronous transmission of power through the first moving plate 402, converting the linear motion of the cylinder into the rotational motion of the gear. The first gear 404 and the second gear 406 on the rotating shaft 405 realize the split transmission of power through coaxial rotation, so that a single power source is converted into driving action in two directions. The second rack 407 converts the rotational motion back into linear motion, driving the first baffle 5 to move. The upper surface of the first moving plate 402 is reinforced by the connecting block 24 to strengthen the connection between the first moving plate 402 and the second baffle 6 and avoid the action jamming.

[0036] The extension and retraction strokes of the dual-head cylinder 401 are precisely limited by the limiting block on the cylinder body. The stroke is fixed to a preset value, which is calibrated according to the height of the ventilation slot 15, the width of the vent hole 16, and the coverage requirements of the baffle. This ensures that the first baffle 5 accurately blocks and opens the ventilation slot 15 and the second baffle 6 accurately blocks and opens the vent hole 16 without any offset or uncovering issues. The above method of calibrating the stroke preset value according to the structural dimensions of the ventilation slot 15, the vent hole 16, and the baffle is existing technology in this field. Its calibration logic is consistent with the stroke setting method of conventional pneumatic components. This application will not make any additional innovative descriptions in this regard.

[0037] The side surface of the first gear 404 meshes with the first rack 403, the side surface of the first baffle 5 slides with the inner wall of the second chamber 3, and the first baffle 5 is correspondingly provided with the ventilation groove 15. The second baffle 6 slides with the top inner wall of the first chamber 2, and the second baffle 6 is correspondingly provided with the vent hole 16.

[0038] The side surface of the first gear 404 meshes with the first rack 403, ensuring the accuracy of power transmission. The side surface of the first baffle 5 slides against the inner wall of the second chamber 3. This sliding not only ensures the smooth movement of the first baffle 5 but also enhances the sealing performance with the chamber wall. The first baffle 5 is correspondingly set with the ventilation slot 15. When the first baffle 5 moves to the position of the ventilation slot 15, it can completely cover the through ventilation slot 15, forming a tight physical barrier to meet the rain protection requirements in rainy weather. The second baffle 6 slides against the top inner wall of the first chamber 2, ensuring the sealing of the opening and closing of the vent 16. The second baffle 6 is correspondingly set with the vent 16. Through the setting of the drive assembly 4, the first baffle 5, and the second baffle 6, the vent 16 is opened when the ventilation slot 15 is blocked, and the double-headed cylinder 401 is activated to extend and move back. When the ventilation slot 15 is open, the vent 16 is blocked.

[0039] The first chamber 2 is equipped with a placement basket 7, and the placement basket 7 is equipped with an adsorption pack 8.

[0040] The placement basket 7 is used to fix the adsorption pack 8 and prevent the adsorption pack 8 from moving around freely in the first chamber 2. The adsorption pack 8 is filled with a highly efficient moisture-absorbing medium. The adsorption pack 8 contains modified silica gel, activated carbon composite material, etc. The modified silica gel and activated carbon composite material have a large specific surface area and strong moisture absorption capacity, which can quickly capture water vapor in the hot and humid airflow that enters the first chamber 2 through the vent 16.

[0041] The external fixed connection of the housing 1 is a heat dissipation fin 17.

[0042] The heat dissipation fins 17 are made of aluminum alloy with high thermal conductivity. When the ventilation slot 15 is open on non-rainy days, the heat dissipation fins 17 can quickly dissipate the heat inside the box 1 into the air. When the ventilation slot 15 is closed on rainy days, the heat dissipation fins 17 can still help dissipate the heat generated by the electrical components in the second chamber 3 through heat conduction, thus avoiding excessive temperature in the closed environment.

[0043] The left and right inner walls of the first chamber 2 are both fixedly connected to a first fixing rod 9. The first fixing rod 9 is provided with a first sliding groove 11. The inner surface of the first sliding groove 11 is slidably connected to a first slider 12. The end of the first slider 12 away from the box body 1 is fixedly connected to a second rack 407.

[0044] The first fixed rod 9 serves as a support and guide structure for the second rack 407, ensuring the stability of the linear motion trajectory of the second rack 407. The first fixed rod 9 has a first groove 11 inside, which provides a moving track for the first slider 12 and restricts the direction of movement. The first slider 14 is rigidly connected to the second rack 407, converting the linear motion of the rack into the sliding of the second slider 12 within the first groove 11. This effectively reduces the shaking of the second rack 407 during movement and ensures the stability of the meshing transmission.

[0045] The left and right inner walls of the second chamber 3 are both fixedly connected to the second fixing rod 10. The second fixing rod 10 is provided with a second sliding groove 13. The inner surface of the second sliding groove 13 is slidably connected to the second slider 14. The end of the second slider 14 away from the box body 1 is fixedly connected to the second moving plate 408.

[0046] The second fixed rod 10 is used to support the second movable plate 408 to ensure the accurate sliding direction of the first baffle 5. The second slide groove 13 provides guidance for the second slider 14. The first fixed rod 9, the second fixed rod 10, the first slide groove 11, the first slider 12, the second slide groove 13, and the second slider 14 constitute the first guide assembly.

[0047] A third fixing rod 21 is fixedly connected to the top inner wall of the first chamber 2. A third sliding groove 22 is provided inside the third fixing rod 21. A third slider 23 is slidably connected to the inner surface of the third sliding groove 22. The end of the third slider 23 away from the third fixing rod 21 is fixedly connected to the first moving plate 402.

[0048] The third fixed rod 21 provides guiding support for the first moving plate 402, ensuring the accurate movement trajectory of the second baffle 6. The third slide groove 22 limits the movement direction of the third slider 23. The third slider 23 is fixedly connected to the first moving plate 402, which can effectively prevent the first moving plate 402 from tilting when it drives the second baffle 6 to move, ensuring the accurate opening and closing of the second baffle 6 to the vent 16. The third fixed rod 21, the third slide groove 22, and the third slider 23 constitute the second guiding component.

[0049] The interior of the housing 1 is provided with a mounting bracket 18, and the front surface of the mounting bracket 18 is provided with a self-adjusting pressure interference socket 19.

[0050] The housing 1 is internally fitted with a mounting bracket 18, which is integrally molded from DMC insulator material that is insulating and resistant to high temperatures. A self-adjusting interference socket 19 is detachably fixed to the front surface of the mounting bracket 18 via bolts. The self-adjusting interference socket 19 is a core electrical connection component of the metering box. It includes a mating plug and a sleeve. Addressing defects such as drift in insertion / extraction force window, poor contact stability after wear, and misalignment, the plug of the self-adjusting interference socket 19 features an integrally molded hyperboloid guide cone with a half-angle design of 20°-30°. This guide cone accurately guides the plug into the sleeve, reducing alignment difficulty and scratch wear during assembly, and preventing concentrated local contact pressure due to assembly deviations. In the buffer section, after the plug enters the sleeve, it first contacts a low-stiffness buffer spring area. This buffer spring is made of beryllium bronze with an equivalent stiffness of 1.2-1.8 N / mm, effectively absorbing ±0.3- The assembly alignment error within 0.6mm and the vibration displacement of the housing 1 are minimized to avoid aggravated wear caused by rigid contact. A high-rigidity locking section connects to the buffer section, with an equivalent stiffness of 3.5-5.0 N / mm, forming a final stable interference fit. The locking section incorporates an S-shaped spring made of SUS304 stainless steel with a thickness of 0.15-0.25mm. This spring can compensate for material aging and interference force attenuation caused by repeated insertions and removals through its own elastic deformation, and the contact temperature rise is ≤70K, consistent with the overall temperature rise limit of the metering box. An elastic support ring, made of fluororubber with a Shore hardness of 60-70HA, is coaxially installed on the inner side of the sleeve, allowing the plug to self-align within a range of ±0.3-0.6mm, effectively reducing contact resistance fluctuations and abnormal temperature rise caused by eccentric contact, further improving contact stability. Through the above structural design, it is ensured that it can operate stably for a long time in the hot and humid working environment of the metering box.

[0051] The materials selected for the aforementioned self-adjusting interference socket 19 are all conventional materials in the field of electrical connections. Its three-section interference fit structure, elastic compensation design, and guiding positioning method are all conventional connector design ideas known in the field. The relevant performance parameters, such as stiffness range, compensation amount, and temperature rise limit, meet the general technical standards for connectors used in existing metering boxes. It is a mature component that can be implemented by those skilled in the art based on existing technology. Its specific structure and working principle have been widely used in the field and belong to the scope of existing technology.

[0052] A third baffle 20 is fixedly connected to the top inner wall of the first chamber 2, a temperature sensor 29 and a humidity sensor 30 are fixedly connected to the left inner wall of the second chamber 3, a rainwater detection sensor 31 is fixedly connected to the upper surface of the housing 1, and a controller 25 is fixedly connected to the front surface of the mounting bracket 18.

[0053] The third baffle 20 in the first chamber 2 is used to limit the movement of the basket 7. The temperature sensor 29 is used to monitor the temperature inside the second chamber 3 in real time. The humidity sensor 30 is used to monitor the humidity inside the second chamber 3 in real time. The rain detection sensor 31 is used to detect whether it is raining outside and provides the core signal for triggering the action of the drive component 4. The front surface of the mounting bracket 18 is fixedly connected to the controller 25. The controller 25 is equipped with a PLC control system. The temperature sensor 29, humidity sensor 30, rain detection sensor 31 and double-headed cylinder 401 in this application are all electrically connected to the controller 25. The method of starting and controlling various sensors and actuators through the controller 25 is the prior art in this field. Its control logic and circuit connection method are relatively mature, and this application will not describe them in detail.

[0054] The interior of the housing 1 is hinged with a first sealing door 26 and a second sealing door 27, and the interior of the housing 1 is provided with a sealing groove 28.

[0055] The second sealing door 27 corresponds to the first chamber 2 and is used for replacing the adsorption pack 8 and inspecting the first chamber 2. The first sealing door 26 corresponds to the second chamber 3 and is used for the installation, debugging, and maintenance of electrical components. Both the first sealing door 26 and the second sealing door 27 adopt a sealing structure. The interior of the housing 1 is provided with a sealing groove 28, which cooperates with the sealing strip of the sealing door to form a double seal, further preventing external rainwater and moisture from intruding and improving the overall sealing performance of the housing 1. The sealing method of the sealing door is prior art in this field, and its basic structure and sealing principle are relatively mature. This application will not elaborate on this further.

[0056] Working principle: When this device is used in rainy weather, the rain detection sensor 31 transmits a signal to the controller 25. The controller 25 drives the double-headed cylinder 401 to extend, which drives the first moving plate 402 and the first rack 403 to move to both ends. The movement of the first rack 403 drives the first gear 404, the rotating shaft 405, and the second gear 406 to rotate, which in turn drives the second rack 407, the second moving plate 408, and the first baffle 5 to move upward. The first baffle 5 accurately blocks the ventilation slot 15 to prevent rainwater from entering the interior of the box 1. At the same time, the first moving plate 402 drives the second baffle 6 to move to both ends through the connecting block 24, so that the ventilation hole 16 is opened. The hot and humid air generated by the internal components of the box 1 enters the first chamber 2 through the ventilation hole 16 and is quickly adsorbed by the adsorption pack 8 in the placement basket 7.

[0057] On sunny days, the controller 25 drives the double-headed cylinder 401 to extend and retract, causing the first moving plate 402 and the first rack 403 to reset. Then, through gear transmission, the second rack 407, the second moving plate 408, and the first baffle 5 move downward. The first baffle 5 disengages from the ventilation slot 15, opening the ventilation slot 15. At the same time, the first moving plate 402 drives the second baffle 6 to reset through the connecting block 24. The second baffle 6 precisely blocks the vent 16. Through the ventilation slot 15 and the external heat dissipation fins 17, the heat inside the box 1 is dissipated more quickly, maintaining a dry internal environment.
