Description

Technical Field

[0001] This invention belongs to the technical field of electricity metering boxes, specifically relating to an electricity metering box with monitoring and temperature control functions. Background Technology

[0002] An energy metering box with monitoring and temperature control functions can monitor the temperature and humidity changes inside the box in real time, and automatically adjust the temperature and humidity inside the box according to the preset temperature and humidity thresholds.

[0003] Patent publication number CN219760372U relates to an energy metering box with monitoring and temperature control functions, specifically in the field of energy metering box technology. The patent includes an energy metering box body, with a temperature and humidity detector at the top for monitoring the internal temperature and humidity. The bottom probe of the temperature and humidity detector penetrates the energy metering box body and is inserted inside for monitoring the internal temperature. The energy metering box body also includes a dehumidification mechanism for dehumidifying the interior. This dehumidification mechanism includes a mounting groove at the top of the energy metering box body, with a dehumidification box inside. This patent not only absorbs moisture from inside the energy metering box to reduce internal humidity but also provides internal lighting, facilitating the inspection and maintenance of electrical components within the energy metering box.

[0004] In existing technologies, temperature and humidity parameters inside the power metering box are monitored by temperature and humidity sensors. When the temperature exceeds a set threshold, the fan is activated to force heat dissipation and regulate the internal temperature of the box. However, in outdoor environments with large day-night temperature differences, the ambient temperature drops significantly at night, and the relative humidity of the air increases. External moisture continuously penetrates into the power metering box. The temperature difference between the inside and outside of the box easily causes water vapor to condense on the side walls of the box and the surface of the meter components, forming condensation, which poses a safety hazard. Summary of the Invention

[0005] Various embodiments of the disclosed technology relate to an energy metering box with temperature monitoring and control functions that can improve the temperature and humidity control effect.

[0006] According to the disclosed embodiments, an energy metering box with monitoring and temperature control functions includes a base, multiple air inlets on the side wall of the base, a box body fixedly mounted on the top of the base, an air outlet on the side wall of the box body, a ventilation opening on the top surface of the base, a controller fixedly penetrating the surface of the box body, a temperature and humidity detection probe on the controller, and the controller monitors the temperature and humidity parameters inside the box body in real time through the temperature and humidity detection probe. The box body also includes: a lead screw motor fixedly mounted on the inner wall of the box body, the controller controlling the start and stop of the lead screw motor; and a mounting plate fixedly penetrating the inner wall of the box body, with a mounting surface fixedly mounted on it. A rectangular frame, the outer wall of which fits against the inner wall of the air outlet; a linear slide rail, which is fixedly mounted on the surface of the mounting plate; a lifting plate, which is slidably mounted on the outer wall of the linear slide rail; a connector, which is fixedly mounted on the lifting plate near the lead screw motor, and has an internally threaded through hole, which is threaded to the lead screw output end of the lead screw motor; when the controller starts the lead screw motor, the lead screw output end of the lead screw motor rotates forward, driving the connector to move upward; a fan, which is fixedly mounted inside the lifting plate, and the controller is used to control the fan's start and stop; and a baffle, which is fixedly mounted on the top of the lifting plate, and is used to close the rectangular frame.

[0007] In some implementations, a ventilation frame is fixedly installed inside the base, with the top of the ventilation frame fixedly penetrating the top surface of the base. A rectangular groove is opened at the top of the ventilation frame. A straight rod is fixedly installed at the bottom of the lifting plate, and a sealing plate is fixedly installed at the bottom of the straight rod. The sealing plate slides through the top surface of the base, and the outer wall of the sealing plate fits against the inner wall of the rectangular groove. When the sealing plate moves down to the starting position, it seals the rectangular groove, forming a sealed cavity inside the box and preventing moisture from entering the box.

[0008] In some implementations, a filter screen is fixedly installed inside the ventilation hole on the top surface of the base. The filter screen is used to filter the air entering the box. External air enters the base through the air inlet, and after being filtered by the filter screen, it enters the box.

[0009] In some implementations, louvers are fixedly installed on the inner side of the rectangular frame of the mounting plate. The louvers are used to block rainwater from entering the box from the air outlet. When it rains, the louvers can effectively block rainwater from entering the box from the air outlet.

[0010] In some implementations, a dehumidification device for absorbing moisture inside the box is provided on the inner wall of the box, and a cleaning device for unblocking the air inlet is provided on the outer wall of the ventilation frame. The dehumidification device includes a fixed frame, a flip plate, a mounting frame, a drying plate, and a rod. The fixed frame is fixedly inserted through the surface of the box, and a round hole is opened on the surface of the fixed frame. The flip plate is rotatably installed on the inner wall of the fixed frame. The mounting frame is fixedly installed on the side of the flip plate near the box. The drying plate is detachably placed between the flip plate and the mounting frame. The rod is detachably placed in the round hole. A limiting groove adapted to the size of the rod is opened on the side wall of the flip plate. The circumferential surface of the rod fits against the inner wall of the limiting groove. The rod is manually pulled out, so that the rod is completely disengaged from the limiting groove on the flip plate, releasing the limiting lock on the flip plate.

[0011] In some implementations, a linkage plate is fixedly installed on the side of the lifting plate away from the lead screw motor. When the lifting plate moves upward along the linear slide rail, the lifting plate drives the linkage plate to move upward. A cover plate is slidably installed on the side of the fixed frame close to the linkage plate, and the cover plate is fixedly connected to the linkage plate.

[0012] In some implementations, the cleaning device includes a fixed plate, a sliding plate, a spring, multiple sets of cleaning rods, and a convex plate. When the bottom surface of the convex plate is in contact with the inner wall of the rectangular groove, the spring is in a stretched deformation state. The fixed plate is fixedly installed on the side of the ventilation frame near the air inlet. The sliding plate slides through the surface of the fixed plate. The spring is disposed between the fixed plate and the sliding plate. Multiple sets of cleaning rods are fixedly installed on the outer wall of the sliding plate. The convex plate is fixedly installed on the side of the sliding plate away from the cleaning rods. Multiple sets of cleaning rods are in contact with the inner wall of the corresponding air inlet. The bottom of the sealing plate has a groove adapted to the size of the convex plate. The convex plate is in contact with the inner wall of the groove, and the bottom surface of the convex plate is in contact with the inner wall of the rectangular groove.

[0013] In some implementations, a striking piece is fixedly installed on the outer wall of the sliding plate, and a connecting frame is fixedly installed on the outer wall of the fixed plate. Multiple sets of elastic steel plates are fixedly installed on the side of the connecting frame near the striking piece. The striking piece and the multiple sets of elastic steel plates collide intermittently, generating high-frequency vibrations.

[0014] This invention provides an energy metering box with temperature monitoring and control functions. It has the following beneficial effects: This invention involves aligning a fan with a rectangular frame and then activating the fan via a controller. The fan forcibly extracts hot air from inside the enclosure. The controller monitors the internal temperature of the enclosure in real time, quickly responding to temperature increases caused by sunlight during the day. When the temperature exceeds the limit, the fan automatically activates for ventilation and heat dissipation, improving the stability and reliability of the outdoor operation of the electricity metering box during the day. Simultaneously, a sealing plate encloses the rectangular groove, creating a sealed cavity inside the enclosure to prevent moisture from entering. By switching modes based on day and night temperature and humidity changes, the fan automatically activates for heat dissipation during the day when high temperatures occur, solving the problem of overheating due to sunlight. At night, the air inlet and outlet automatically close to prevent moisture from entering the enclosure, achieving a dual protection effect of temperature control and moisture prevention.

[0015] This invention exposes the drying plate inside the chamber, allowing it to fully contact and absorb residual trace amounts of moisture. The cover automatically closes during the day to prevent premature saturation and failure of the drying plate. At night, after the chamber is sealed, the cover automatically opens, allowing the drying plate to specifically absorb any remaining moisture, thus improving the moisture-proof effect. Simultaneously, manually pulling out the insert rod completely disengages it from the limiting groove on the flip plate, quickly securing the flip plate and effectively reducing the difficulty of daily maintenance. This facilitates easy replacement of the drying plate by operators, maintaining a dry state inside the chamber.

[0016] This invention features a dust-removing rod that adheres to the inner wall of the air inlet, clearing the air inlet and preventing blockage. During each day-night cycle, as the lifting plate moves, the dust-removing rod clears the air inlet, preventing dust accumulation from clogging it and reducing airflow. This ensures that the temperature control and heat dissipation effect is not affected by dust accumulation. Simultaneously, the high-frequency vibration generated by the collision is transmitted through the sliding plate to multiple sets of dust-removing rods, and then from the rods to the inner wall of the air inlet. Each time the dust-removing rod clears the air inlet, the striking plate collides with multiple sets of elastic steel plates, generating high-frequency vibration, which is then applied to the air inlet. This improves both the smoothness of the dust-removing rod's movement and the effectiveness of the clearing process. Attached Figure Description

[0019] The following is in conjunction with the appendix Figure 1-7 The invention will be further described in detail with reference to specific embodiments, but these are not intended to limit the invention: One embodiment of the present invention is: an energy metering box with monitoring and temperature control function, including a base 1, with multiple air inlets on the side wall of the base 1, a box body 2 fixedly installed on the top of the base 1, an air outlet on the side wall of the box body 2, a ventilation opening on the top surface of the base 1, a controller 3 fixedly passing through the surface of the box body 2, and a temperature and humidity detection probe installed on the controller 3; further including: a lead screw motor 4, fixedly installed on the inner wall of the box body 2, the controller 3 being used to control the start and stop of the lead screw motor 4; a mounting plate 5, fixedly passing through the inner wall of the box body 2, with a rectangular frame fixedly installed on the surface of the mounting plate 5, the outer wall of the rectangular frame fitting against the inner wall of the air outlet; and a linear slide rail 6, fixedly installed on the mounting plate. 5. Surface; Lifting plate 7, which is slidably installed on the outer wall of the linear guide rail 6; Connector 8, which is fixedly installed on the side of the lifting plate 7 near the lead screw motor 4, and has an internal threaded through hole, which is threadedly connected to the lead screw output end of the lead screw motor 4; Fan 9, which is fixedly installed inside the lifting plate 7, and the controller 3 is used to control the start and stop of the fan 9; Baffle 10, which is fixedly installed on the top of the lifting plate 7, and is used to close the rectangular frame. The controller 3 monitors the internal temperature of the box 2 in real time, quickly responds to the temperature rise caused by sunlight during the day, and automatically turns on the fan 9 for ventilation and heat dissipation when the temperature exceeds the standard, thereby improving the reliability of temperature control.

[0020] A ventilation frame 11 is fixedly installed inside the base 1. The top of the ventilation frame 11 is fixedly inserted through the top surface of the base 1. A rectangular groove is opened at the top of the ventilation frame 11. A straight rod 12 is fixedly installed at the bottom of the lifting plate 7. A sealing plate 13 is fixedly installed at the bottom of the straight rod 12. The sealing plate 13 slides through the top surface of the base 1. The outer wall of the sealing plate 13 is in contact with the inner wall of the rectangular groove. By switching modes according to the changes in temperature and humidity during the day and night, the air inlet and outlet are automatically closed at night to prevent moisture from entering the box 2, thus achieving the dual protection effect of temperature control and moisture prevention.

[0021] A filter screen 14 is fixedly installed inside the ventilation hole on the top surface of the base 1. The filter screen 14 is used to filter the air entering the box 2. By setting the filter screen 14, the air inside the box 2 is kept clean.

[0022] A louver 15 is fixedly installed on the inner side of the rectangular frame of the mounting plate 5. The louver 15 is used to prevent rainwater from entering the interior of the box 2 from the air outlet. By setting the louver 15, the safety of the box 2 when used outdoors is improved.

[0023] In this embodiment, when the controller 3 is working, it monitors the temperature and humidity parameters inside the cabinet 2 in real time through the temperature and humidity detection probe. When the environment of the cabinet 2 changes from night to day, the temperature inside the cabinet 2 gradually increases with the increase of light intensity. When the temperature inside the cabinet 2 exceeds the set temperature threshold, the controller 3 first starts the lead screw motor 4. The lead screw output end of the lead screw motor 4 rotates forward, driving the connecting piece 8 to move upward. The connecting piece 8 drives the lifting plate 7 to move upward along the linear slide rail 6. The lifting plate 7 drives the fan 9 to move upward. At the same time, the lifting plate 7 drives the baffle 10 and the straight rod 12 to move upward. The straight rod 12 drives the sealing plate 13 to move upward. During the upward movement, the baffle 10 gradually detaches from the rectangular frame, releasing the enclosure of the rectangular frame. At the same time, the bottom surface of the sealing plate 13, which moves upward synchronously, separates from the inner wall of the rectangular groove, releasing the enclosure of the rectangular groove. At this time, external air enters the base 1 through the air inlet, and after being filtered by the filter screen 14, it enters the box 2. When the lifting plate 7 moves to the preset position, the controller 3 controls the screw motor 4 to lock itself. At this time, the fan 9 is aligned with the rectangular frame, and the controller 3 starts the fan 9 again. The fan 9 forcibly extracts the hot air inside the box 2, and quickly cools the inside of the box 2. The controller 3 monitors the temperature inside the box 2 in real time, quickly responds to the heating problem caused by sunlight during the day, and automatically turns on the fan 9 for ventilation and heat dissipation when the temperature exceeds the standard, improving the stability and reliability of the outdoor operation of the power metering box during the day. When the environment around the cabinet 2 changes from daytime to nighttime, the humidity around the cabinet 2 continues to increase. When the humidity inside the cabinet 2 exceeds the set humidity threshold, the controller 3 first turns off the fan 9, and then starts the lead screw motor 4. The lead screw output end of the lead screw motor 4 reverses, driving the connecting piece 8 to move down. The connecting piece 8 drives the lifting plate 7 to move down along the linear slide rail 6. The lifting plate 7 drives the fan 9 to move down. At the same time, the lifting plate 7 drives the baffle 10 and the straight rod 12 to move down. The straight rod 12 drives the sealing plate 13 to move down. During the downward movement, the baffle 10 gradually conforms to the rectangular frame until it returns to its initial position, sealing the rectangular frame. Simultaneously, the sealing plate 13, which moves to the initial position, conforms to the inner wall of the rectangular groove with its bottom surface, sealing the rectangular groove and forming a sealed cavity inside the box 2. This prevents moisture from entering the box 2. By switching modes according to day and night temperature and humidity changes, the fan 9 automatically turns on to dissipate heat during the day when the temperature is high, solving the problem of overheating due to sunlight. At night, the air inlet and outlet are automatically closed to prevent moisture from entering the box 2, achieving a dual protection effect of temperature control and moisture prevention.

[0024] Please see Figure 1 - Figure 7 Based on the above embodiments, in another embodiment of the present invention, a dehumidification device for absorbing moisture inside the box 2 is provided on the inner wall of the box 2, and a cleaning device for unblocking the air inlet is provided on the outer wall of the ventilation frame 11. The dehumidification device includes a fixed frame 21, a flip plate 22, a mounting frame 23, a drying plate 24, and a rod 25. The fixed frame 21 is fixedly inserted through the surface of the box 2, and a round hole is opened on the surface of the fixed frame 21. The flip plate 22 is rotatably installed on the inner wall of the fixed frame 21. The mounting frame 23 is fixedly installed on the side of the flip plate 22 near the box 2. The drying plate 24 is detachably placed between the flip plate 22 and the mounting frame 23. The rod 25 is detachably placed in the round hole. A limiting groove adapted to the size of the rod 25 is opened on the side wall of the flip plate 22. The circumferential surface of the rod 25 fits against the inner wall of the limiting groove. The quick fixation of the flip plate 22 by the rod 25 effectively reduces the difficulty of daily maintenance and facilitates the replacement of the drying plate 24 by the operator, maintaining the dry state inside the box 2.

[0025] A linkage plate 26 is fixedly installed on the side of the lifting plate 7 away from the lead screw motor 4. A cover plate 27 is slidably installed on the side of the fixing frame 21 close to the linkage plate 26. The cover plate 27 is fixedly connected to the linkage plate 26. The cover plate 27 is automatically closed during the day to prevent the drying plate 24 from becoming saturated and ineffective in advance. At night, after the box 2 is sealed, the cover plate 27 is automatically opened, and the drying plate 24 is used to specifically absorb the residual moisture inside, thereby improving the moisture-proof effect.

[0026] The cleaning device includes a fixed plate 31, a sliding plate 32, a spring 33, multiple sets of dust removal rods 34, and a protruding plate 35. The fixed plate 31 is fixedly installed on the side of the ventilation frame 11 near the air inlet. The sliding plate 32 slides through the surface of the fixed plate 31. The spring 33 is located between the fixed plate 31 and the sliding plate 32. Multiple sets of dust removal rods 34 are fixedly installed on the outer wall of the sliding plate 32. The protruding plate 35 is fixedly installed on the side of the sliding plate 32 away from the dust removal rods 34. The multiple sets of dust removal rods 34 are fitted with the inner wall of the corresponding air inlet. The bottom of the sealing plate 13 has a groove adapted to the size of the protruding plate 35. The protruding plate 35 is fitted with the inner wall of the groove. The bottom surface of the protruding plate 35 is fitted with the inner wall of the rectangular groove. During each day and night alternation, when the lifting plate 7 moves, the dust removal rods 34 clear the air inlet, preventing the hole from being blocked by dust accumulation, which would reduce the airflow rate and ensure that the temperature control and heat dissipation effect is not affected by dust accumulation.

[0027] A striking plate 36 is fixedly installed on the outer wall of the sliding plate 32, and a connecting frame 37 is fixedly installed on the outer wall of the fixed plate 31. Multiple sets of elastic steel plates 38 are fixedly installed on the side of the connecting frame 37 near the striking plate 36. Each time the cleaning rod 34 clears the air inlet hole, the striking plate 36 collides with the multiple sets of elastic steel plates 38 to generate high-frequency vibration, and the vibration is applied to the air inlet hole, which not only improves the smoothness of the movement of the cleaning rod 34, but also improves the clearing effect.

[0028] In this embodiment, when the lifting plate 7 moves upward along the linear slide rail 6, the lifting plate 7 drives the linkage plate 26 to move upward, and the linkage plate 26 drives the cover plate 27 to move upward until the cover plate 27 closes the fixed frame 21 to the side near the inside of the box 2, and cooperates with the flip plate 22 to form a sealed cavity inside the fixed frame 21. When the lifting plate 7 moves down along the linear slide rail 6, the lifting plate 7 drives the linkage plate 26 to move down, and the linkage plate 26 drives the cover plate 27 to move down until the cover plate 27 returns to the starting position, so that the drying plate 24 is exposed inside the box 2, fully contacting and absorbing the trace amount of moisture remaining inside the box 2. By automatically closing the cover plate 27 during the day, the drying plate 24 is prevented from becoming saturated and ineffective in advance. At night, after the box 2 is sealed, the cover plate 27 is automatically opened, and the drying plate 24 is used to specifically absorb the residual moisture inside, thereby improving the moisture-proof effect. When replacing the drying plate 24, manually pull out the insert rod 25 to completely disengage the insert rod 25 from the limiting groove on the flip plate 22, releasing the limiting lock on the flip plate 22. Then open the flip plate 22 away from the chamber 2. The flip plate 22 drives the mounting frame 23 to rotate synchronously, thereby driving the drying plate 24 to rotate. Then pull out the drying plate 24 for replacement. Then reset the flip plate 22 to the starting position. Finally, insert the insert rod 25 to limit and lock the flip plate 22, completing the quick replacement of the drying plate 24. The quick fixation of the flip plate 22 by the insert rod 25 effectively reduces the difficulty of daily maintenance, making it convenient for operators to replace the drying plate 24 and maintain the dry state inside the chamber 2. When the bottom surface of the convex plate 35 is in contact with the inner wall of the rectangular groove, the spring 33 is in a state of tension deformation. At this time, the sealing plate 13 moves upward, and the deformed spring 33 resets under its own elasticity, driving the sliding plate 32 to move upward. The sliding plate 32 drives the cleaning rod 34 and the convex plate 35 to move upward. During the upward movement, the cleaning rod 34, which is in contact with the inner wall of the air inlet, clears the air inlet and prevents blockage in the hole. When the sealing plate 13 moves down, the groove at the bottom of the sealing plate 13 pushes the convex plate 35 down, the convex plate 35 drives the sliding plate 32 down, the sliding plate 32 stretches the spring 33 to deform it, and drives the cleaning rod 34 down to clear the air inlet again, ensuring that there is no blockage inside the air inlet. Through each day and night alternation, when the lifting plate 7 moves, the cleaning rod 34 clears the air inlet to avoid blockage due to dust accumulation inside the hole, which would reduce the air circulation rate and ensure that the temperature control heat dissipation effect is not affected by dust accumulation. When the sliding plate 32 moves up and down along the inner wall of the fixed plate 31, the sliding plate 32 drives the striking plate 36 to move synchronously. Each time it moves, the striking plate 36 intermittently collides with multiple sets of elastic steel plates 38. The high-frequency vibration generated by the collision is transmitted through the sliding plate 32 to multiple sets of cleaning rods 34, and then from the cleaning rods 34 to the inner wall of the air inlet, ensuring the smoothness of the movement of the cleaning rods 34 along the inner wall of the air inlet. Each time the cleaning rods 34 clear the air inlet, the striking plate 36 collides with multiple sets of elastic steel plates 38 to generate high-frequency vibration, and the vibration is applied to the air inlet, which not only improves the smoothness of the movement of the cleaning rods 34, but also improves the clearing effect.
