Description

Technical Field

[0001] The invention relates to the technical field of electric energy metering boxes, in particular to a modular outdoor electric energy metering box. Background Art

[0002] With the continuous development of social economy and scientific and technological progress, the rapid development of electronic information technology has laid the foundation for the intelligent upgrade of electricity meter boxes. High-precision digital electricity meters are constantly emerging, which can accurately measure tiny changes in electricity, and have data storage and transmission functions, and can record and report electricity usage in real time. The electricity meter box is an indispensable part of power engineering. The electricity meter box is a device for measuring electric energy. It includes an electricity meter, a voltage transformer for measurement, a current transformer and its secondary circuit, as well as auxiliary equipment such as an electricity metering panel, cabinet and box. The electricity meter box is usually used in low-voltage power distribution devices. Its working principle is to assemble switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-closed metal cabinet or screen.

[0003] Traditional outdoor energy meter boxes often rely on natural ventilation or simple heat dissipation, such as heat dissipation through ventilation holes alone. This method has a very limited cooling effect in a high temperature environment and is difficult to effectively remove the heat accumulated in the box, which can easily cause the temperature inside the box to be too high. In addition, during the installation and maintenance of traditional outdoor energy meter boxes, a large amount of manual operation is required, which increases the investment in labor and time costs. Summary of the invention

[0004] 1. Technical issues to be resolved

[0009] The first and second bidirectional threaded rods are rotatably connected to the inner wall of the fixing plate on both sides, and threaded sleeves are threadedly arranged on both sides of the outer walls of the first and second bidirectional threaded rods, and the lower ends of the threaded sleeves are fixedly connected to clamping plates, the outer wall of the box body and the other side of the inner wall of the third installation cavity are provided with a first connecting hole, and the inner wall of the third installation cavity is provided with a second connecting hole on one side, a semiconductor cooling plate is arranged on one side of the inner wall of the first connecting hole, and a one-way valve is arranged on one side of the inner wall of the second connecting hole;

[0010] A wind dispersing assembly is fixedly connected to the front end of the other side of the inner wall of the second installation cavity, and the wind dispersing assembly includes a diverter cover, and a distribution plate is arranged inside the diverter cover, and distribution holes are opened at the upper and lower ends of one side of the distribution plate, and a clamping plate is evenly fixedly connected to the front end of one side of the inner wall of the second installation cavity, and a desiccant is clamped inside the clamping plate;

[0011] Through the above technical solution, when the temperature sensor inside the second installation cavity detects that the temperature exceeds a preset threshold, the semiconductor refrigeration plate is powered on to generate a cold end and a hot end. At this time, the second exhaust fan is started through the control panel to accelerate the heat dissipation of the hot end of the semiconductor refrigeration plate, so that its cold end can effectively absorb the heat inside the third installation cavity. When the control panel detects that the temperature sensor threshold inside the third installation cavity is 2°-3° lower than the temperature sensor threshold inside the second installation cavity, the control panel will start the first exhaust fan to push open the one-way valve to allow the cold air inside the third installation cavity to exchange with the hot air inside the second installation cavity until the temperature sensor inside the second installation cavity detects that the temperature drops to the set threshold, and the semiconductor refrigeration plate, exhaust fan and other related components stop working, thereby achieving a cooling effect.

[0012] Preferably, three servo motors are evenly and fixedly connected to the rear end of one side of the inner wall of the second installation cavity, and the output ends of the servo motors pass through the fixing plate to the inside of the fixing plate and are fixedly connected to one side of the first bidirectional threaded rod;

At the same time, the sliding connection between the clamping plate and the fixed plate ensures the linearity and stability of the clamping plate movement.

[0016] Preferably, the second exhaust fan is fixedly connected to the other side of the inner wall of the first connection hole, and the first exhaust fan is fixedly connected to the other side of the inner wall of the second connection hole;

When temperature control is required, the first row of fans can promptly push the cold air from the third installation cavity to the second installation cavity, thereby realizing the rapid exchange of cold and hot air and quickly adjusting the temperature of the second installation cavity.

[0018] Preferably, the other side of the outer wall of the flow divider and the distribution plate are fixedly connected to the inner wall of the second installation cavity, and the interior of the distribution plate is connected to the interior of the second connection hole;

[0019] Through the above technical solution, the through connection between the distribution plate and the second connecting hole enables the cold air entering the second installation cavity from the third installation cavity to be effectively dispersed by the distribution plate first, thereby avoiding the cold air directly impacting the local area and causing uneven temperature.

[0020] Preferably, a circuit breaker is fixedly connected to the upper portion of the rear end of the inner wall of the first installation cavity, and a connecting rod is provided on the upper portion of the inner wall of the second installation cavity close to the fixing plate, and one side of the connecting rod passes through the second installation cavity to the inside of the first installation cavity;

[0021] Through the above technical solution, the setting of the circuit breaker provides overcurrent and short-circuit protection functions for the electrical system of the entire meter box. When abnormal current appears in the circuit, it can quickly cut off the circuit to protect the electric energy meter and other electrical equipment from damage, thereby improving the safety of equipment operation. The connecting rod connects the electric energy meter to the circuit breaker, which facilitates the monitoring and control of the power consumption of the electric energy meter. Once the electric energy meter or the circuit in which it is located fails, the circuit breaker can respond in time. At the same time, it is also convenient for unified management and analysis of electric energy metering and related electrical parameters on the control panel.

[0022] Preferably, electric energy meters are arranged on both sides of the upper end of the fixing plate, wherein the electric energy meters are arranged between adjacent clamping plates, and the electric energy meters are fixed to the inner wall of the second installation cavity by bolts;

[0026] (III) Beneficial effects

[0027] The present invention provides a modular outdoor electric energy metering box, which has the following beneficial effects:

[0028] 1. The present invention provides a modular outdoor electricity metering box. When the temperature sensor inside the second installation cavity detects that the temperature exceeds a preset threshold, the semiconductor refrigeration plate is powered on to generate a cold end and a hot end. At this time, the second exhaust fan is started through the control panel to accelerate the heat dissipation of the hot end of the semiconductor refrigeration plate, so that its cold end can effectively absorb the heat inside the third installation cavity. When the control panel detects that the temperature sensor threshold inside the third installation cavity is 2°-3° lower than the temperature sensor threshold inside the second installation cavity, the control panel will start the first exhaust fan to push open the one-way valve to allow the cold air inside the third installation cavity to exchange with the hot air inside the second installation cavity until the temperature sensor inside the second installation cavity detects that the temperature drops to the set threshold, and the semiconductor refrigeration plate, exhaust fan and other related components stop working, thereby achieving a cooling effect.

[0029] 2. The present invention provides a modular outdoor electricity meter box. When installing the electricity meter, the electricity meter is placed on a fixed plate, and the servo motor is started with the help of a control panel. After the servo motor is started, it drives the first bidirectional threaded rod to rotate. Since the other side of the first bidirectional threaded rod is fixedly connected to one side of the second bidirectional threaded rod, the second bidirectional threaded rod also rotates therewith. The rotation of the first bidirectional threaded rod and the second bidirectional threaded rod drives the threaded sleeves of the outer wall threads to move, and the lower end of the threaded sleeve is fixedly connected to a clamping plate, so that the clamping plates are close to each other, thereby achieving stable clamping of the electricity meter before installation. In this stable clamping state, the electricity meter only needs to be fixed to the fixed plate by bolts. The whole process does not require additional manpower assistance, which effectively improves the convenience and efficiency of installation.

[0030] 3. The present invention provides a modular outdoor electricity metering box. When the gas inside the third installation cavity enters the second installation cavity, it will first be dispersed by the distribution plate in the wind dispersion component, and then evenly distributed through the distribution holes, effectively avoiding excessive cooling of a certain place in the second installation cavity.

[0051] The first bidirectional threaded rod 303 and the second bidirectional threaded rod 304 are rotatably connected to both sides of the inner wall of the fixing plate 301, and the threaded sleeves 305 are threadedly arranged on both sides of the outer walls of the first bidirectional threaded rod 303 and the second bidirectional threaded rod 304, and the lower ends of the threaded sleeves 305 are fixedly connected to the clamping plates 306, and the outer wall of the box body 1 and the other side of the inner wall of the third installation cavity 6 are provided with a first connecting hole 7, and the inner wall of the third installation cavity 6 is provided with a second connecting hole 8. A semiconductor cooling plate 17 is arranged on one side of the inner wall of the first connecting hole 7, and a one-way valve 18 is arranged on one side of the inner wall of the second connecting hole 8;

[0052] A wind dispersion component 9 is fixedly connected to the front end of the other side of the inner wall of the second installation cavity 5. The wind dispersion component 9 includes a flow divider 901. A distribution plate 902 is arranged inside the flow divider 901. Distribution holes 903 are provided at the upper and lower ends of one side of the distribution plate 902. A clamping plate 15 is evenly fixedly connected to the front end of one side of the inner wall of the second installation cavity 5. A desiccant 16 is clamped inside the clamping plate 15.

[0053] When the temperature sensor 21 inside the second installation cavity 5 detects that the temperature exceeds a preset threshold, the semiconductor refrigeration chip 17 is powered on to generate a cold end and a hot end. At this time, the second exhaust fan 20 is started through the control panel 13 to accelerate the heat dissipation of the hot end of the semiconductor refrigeration chip 17, so that its cold end can effectively absorb the heat inside the third installation cavity 6. When the control panel 13 detects that the threshold of the temperature sensor 21 inside the third installation cavity 6 is 2°-3° lower than the threshold of the temperature sensor 21 inside the second installation cavity 5, the control panel 13 will start the first exhaust fan 19 to push open the one-way valve 18, so that the cold air inside the third installation cavity 6 is exchanged with the hot air inside the second installation cavity 5, until the temperature sensor 21 inside the second installation cavity 5 detects that the temperature drops to the set threshold, and the semiconductor refrigeration chip 17, the exhaust fan and other related components stop working, thereby achieving a cooling effect.

[0054] Three servo motors 302 are evenly fixedly connected to the rear end of one side of the inner wall of the second installation cavity 5, and the output end of the servo motor 302 passes through the fixed plate 301 to the interior of the fixed plate 301 and is fixedly connected to one side of the first bidirectional threaded rod 303, which can adapt to the installation of electric energy meters 10 of various sizes and layout requirements, and the control of the servo motor 302 can reduce human operation errors, ensure the stability and accuracy of the installation of the electric energy meter 10, and is conducive to the stable development of subsequent metering work. The other side of the first bidirectional threaded rod 303 is fixedly connected to one side of the second bidirectional threaded rod 304, and the outer walls of the clamping plate 306 are slidably connected to the inner wall of the fixed plate 301. The linkage design of the first bidirectional threaded rod 303 and the second bidirectional threaded rod 304 enables the threaded sleeves 305 and the clamping plate 306 on both sides to move synchronously and symmetrically when the servo motor 302 is driven, ensuring that the clamping force on the electric energy meter 10 is evenly distributed. At the same time, the sliding connection between the clamping plate 306 and the fixed plate 301 ensures the linearity and stability of the movement of the clamping plate 306.

[0055] A second exhaust fan 20 is fixedly connected to the other side of the inner wall of the first connecting hole 7, and a first exhaust fan 19 is fixedly connected to the other side of the inner wall of the second connecting hole 8. The second exhaust fan 20 enhances the heat dissipation efficiency of the hot end of the semiconductor refrigeration plate 17, so that the refrigeration plate can continuously and efficiently generate cold air, maintain a stable refrigeration effect, and ensure the cooling speed and effect of the third installation cavity 6. When temperature control is required, the first exhaust fan 19 can promptly push the cold air from the third installation cavity 6 to the second installation cavity 5, thereby realizing the rapid exchange of cold and hot air and quickly adjusting the temperature of the second installation cavity 5.

[0056] The other side of the outer wall of the splitter hood 901 and the distribution plate 902 are fixedly connected to the inner wall of the second installation cavity 5, and the interior of the distribution plate 902 is connected through the interior of the second connection hole 8. The through connection between the distribution plate 902 and the second connection hole 8 allows the cold air entering the second installation cavity 5 from the third installation cavity 6 to be effectively dispersed by the distribution plate 902 first, thereby avoiding the situation where the cold air directly impacts the local area and causes uneven temperature. The upper part of the rear end of the inner wall of the first installation cavity 4 is fixedly connected with a circuit breaker 11, and the upper part of the inner wall of the second installation cavity 5 near the fixed plate 301 is provided with a connecting rod 12, and one side of the connecting rod 12 passes through the second installation cavity 5 to the inside of the first installation cavity 4, the circuit breaker 11 is set to provide over-current and short-circuit protection functions for the electrical system of the entire meter box. When abnormal current appears in the circuit, the circuit can be quickly cut off to protect the electric energy meter 10 and other electrical equipment from damage, thereby improving the safety of equipment operation. The connecting rod 12 connects the electric energy meter 10 with the circuit breaker 11, which is convenient for monitoring and controlling the power consumption of the electric energy meter 10. Once the electric energy meter 10 or the circuit in which it is located fails, the circuit breaker 11 can be used to respond in time, and it is also convenient to uniformly manage and analyze the electric energy metering and related electrical parameters on the control panel 13.

[0057] The electric energy meter 10 is arranged on both sides of the upper end of the fixing plate 301, wherein the electric energy meter 10 is arranged between the adjacent clamping plates 306, and the electric energy meter 10 is fixed to the inner wall of the second installation cavity 5 by bolts. The clamping of the electric energy meter 10 by the adjacent clamping plates 306 provides preliminary fixation and positioning for the electric energy meter 10, ensuring the stability of the electric energy meter 10 during the installation process, and the electric energy meter 10 is further fixed to the inner wall of the second installation cavity 5 by bolts, so that the installation of the electric energy meter 10 is more firm and reliable. The upper end of one side of the inner wall of the third installation cavity 6 and the upper part of one side of the inner wall of the second installation cavity 5 are both provided with a temperature sensor 2 1, a control panel 13 is fixedly connected to the middle of the rear end of the inner wall of the first installation cavity 4, and a sealing gasket 14 is arranged at the front end of the outer wall of the box body 1 near the edge of the first installation cavity 4, the second installation cavity 5 and the third installation cavity 6. The temperature sensors 21 in the two cavities can monitor the temperature changes in their respective cavities in real time and accurately, and transmit the data to the control panel 13. The control panel 13 controls the operation of the semiconductor refrigeration sheet 17, the exhaust fan and other equipment according to the preset temperature threshold and control logic, thereby realizing the adjustment of the internal temperature of the metering box, so that the temperature is always maintained within a range suitable for the operation of the equipment.

[0058] Working principle: The interior of the box body 1 is divided into three chambers, namely the first installation chamber 4, the second installation chamber 5 and the third installation chamber 6. In the second installation chamber 5, the first two-way threaded rod 303 and the second two-way threaded rod 304 are rotatably connected on both sides of the inner wall of the fixing plate 301 of each stabilizing component 3, and the threaded sleeves 305 on both sides of the outer walls of the first two-way threaded rod 303 and the second two-way threaded rod 304 are connected to the clamping plate 306, and the servo motor 302 at the rear end of one side of the inner wall of the second installation chamber 5 is connected to the first two-way threaded rod 303. At the same time, the electric energy meter 10 is placed on the fixing plate 301 and electrically connected to the circuit breaker 11 of the first installation chamber 4 through the connecting rod 12, and the clamping plate 15 A desiccant 16 is clamped inside for moisture absorption. The shunt cover 901 and the distribution plate 902 in the wind dissipation component 9 are also installed at the front end of one side of the inner wall of the second installation cavity 5 and connected to the ventilation structure of the third installation cavity 6. A first connecting hole 7 is provided on the outer wall of the box body 1 and the other side of the inner wall of the third installation cavity 6, in which a semiconductor cooling plate 17 and a second exhaust fan 20 are arranged. A one-way valve 18 and a first exhaust fan 19 are arranged at the second connecting hole 8 on one side of the inner wall of the third installation cavity 6, and a temperature sensor 21 is installed on the upper part of one side of the inner wall of the third installation cavity 6 and the second installation cavity 5. A control panel 13 is fixed in the middle of the rear end of the first installation cavity 4, and a sealing pad 14 is arranged at the edge of the box body 1 to ensure sealing.

[0059] When it is necessary to install the electric energy meter 10, first place the electric energy meter 10 on the fixing plate 301 of the second installation cavity 5 at a roughly predetermined position, then, by operating the control panel 13 in the middle of the rear end of the first installation cavity 4, start the servo motor 302 at the rear end of one side of the inner wall of the second installation cavity 5, the servo motor 302 starts to run, and its output end drives the first bidirectional threaded rod 303 fixedly connected thereto to rotate, and since the other side of the first bidirectional threaded rod 303 is fixedly connected to the second bidirectional threaded rod 304, the second bidirectional threaded rod 304 also rotates synchronously, and with the rotation of the first bidirectional threaded rod 303 and the second bidirectional threaded rod 304, the threaded sleeve 305 provided on the outer wall of the threaded sleeve 305 starts to move, because The lower end of the threaded sleeve 305 is fixedly connected to the clamping plate 306, so the clamping plates 306 are driven by the threaded sleeve 305 to move closer to each other, and stably and accurately clamp the electric energy meter 10 placed on the fixed plate 301. After the clamping plate 306 completes the stable clamping of the electric energy meter 10, the operator only needs to use bolts to firmly fix the electric energy meter 10 on the fixed plate 301 to complete the installation of the electric energy meter 10. The entire installation process is controlled by the control panel 13 on the servo motor 302, realizing an automated clamping operation, without the need for additional manpower to perform complex and unstable manual clamping actions, thereby improving the convenience and efficiency of installation, and also ensuring the accuracy and stability of the installation of the electric energy meter 10.

[0060] During the normal operation of the electric energy meter box, the temperature adjustment function automatically operates to maintain a suitable ambient temperature. When the temperature sensor 21 inside the second installation cavity 5 detects that the cavity temperature exceeds the threshold value pre-set in the control panel 13, the semiconductor refrigeration plate 17 installed at the first connection hole 7 on the outer wall of the box body 1 and the other side of the inner wall of the third installation cavity 6 is immediately powered on and starts to work, generating a cold end and a hot end. At the same time, the control panel 13 starts the second exhaust fan 20 at the first connection hole 7 on the same side as the semiconductor refrigeration plate 17. The second exhaust fan 20 rotates rapidly to accelerate the flow of air around the hot end of the semiconductor refrigeration plate 17, thereby effectively accelerating the heat dissipation process, so that the cold end of the semiconductor refrigeration plate 17 can absorb heat with higher efficiency. At this time, the cold end mainly absorbs heat from the inside of the third installation cavity 6, so that the temperature of the third installation cavity 6 gradually decreases. As the temperature of the third installation cavity 6 continues to decrease, when the control panel 13 detects that the threshold value of the temperature sensor 21 inside the third installation cavity 6 is 2°-3° lower than the threshold value of the temperature sensor 21 inside the second installation cavity 5, the control panel 13 quickly starts the first exhaust fan 19 at the second connection hole 8 on one side of the inner wall of the third installation cavity 6. After the first exhaust fan 19 is started, it pushes open the adjacent one-way valve 18, so that the cold air inside the third installation cavity 6 enters the second installation cavity 5 through the one-way valve 18 under the drive of the first exhaust fan 19, and fully exchanges with the hot air inside the second installation cavity 5;

[0061] When the gas in the third installation cavity 6 enters the second installation cavity 5, the gas will first be dispersed by the distribution plate 902 in the air dispersion component 9, and then evenly distributed through the distribution holes 903 on the distribution plate 902, effectively avoiding excessive cooling of a certain place in the second installation cavity 5, and ensuring the uniformity and stability of the temperature drop in the second installation cavity 5;

[0062] This process of heat exchange will continue until the temperature sensor 21 inside the second installation cavity 5 detects that the temperature has dropped to a preset threshold value. At this time, the control panel 13 controls the semiconductor refrigeration plate 17, the first exhaust fan 19, the second exhaust fan 20 and other related components to stop working according to the data fed back by the temperature sensor 21, completing a complete cooling cycle operation, so that the temperature of the second installation cavity 5 can always be maintained within an appropriate range, providing a stable and suitable operating environment for the equipment in the electricity meter box, and ensuring the normal operation and service life of the equipment.
