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] Existing electricity metering boxes are mostly installed outdoors or in distribution rooms. The internal current transformers, terminals and other components are constantly in operation and are prone to local overheating due to increased load or poor contact. Traditional metering boxes rely solely on passive heat dissipation structures and lack active monitoring and intelligent control of the temperature of key internal points. The continuous accumulation of high temperature not only accelerates insulation aging and increases metering errors, but may also cause fire hazards. Therefore, there is an urgent need for an electricity metering box with real-time temperature monitoring and automatic temperature control functions.

The bottom probe of the detector penetrates the energy metering box body and is inserted inside for monitoring the internal temperature. The box body also includes a dehumidification mechanism for dehumidifying the interior. This mechanism includes a mounting groove at the top of the box body containing a dehumidification box. This patent can absorb moisture from inside the energy metering box to reduce internal humidity and also provides internal lighting, facilitating the inspection and maintenance of electrical components within the box.

[0004] The above-mentioned device also has the following problems: When monitoring and controlling the temperature of the power metering box and the power metering equipment inside the power metering box, it is difficult to keep the power metering equipment inside the box away from each other.

[0020] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] like Figures 1-8As shown, one embodiment of the present invention is an energy metering box with monitoring and temperature control functions, comprising: a box body 1, a protective plate 2 fixedly connected to the top of the box body 1, a ventilation plate 3 fixedly connected to the inner wall of the box body 1, a guide rod 4 provided inside the box body 1, a ventilation mechanism 5 provided on the left side of the box body 1, a protective mechanism 6 provided on the top of the ventilation mechanism 5, a double-headed electric telescopic rod 7 provided inside the box body 1, a connecting block 8 fixedly connected to the telescopic end of the double-headed electric telescopic rod 7, and a movable plate 9 fixedly connected to the front of the connecting block 8. The front of the box 1 is fixedly connected to the mounting part 10, and the mounting part 10 is equipped with an energy metering device. The inner wall of the connecting block 8 is rotatably connected to the reciprocating screw 11, and the circumferential surface of the reciprocating screw 11 is movably connected to the movable block 12. The rear of the movable block 12 is fixedly connected to the limit block 13, the front of the movable block 12 is fixedly connected to the cooling nozzle 14, and the circumferential surface of the cooling nozzle 14 is fixedly connected to the connecting air pipe 15. The rear of the box 1 is equipped with a filter fan, the mounting part 10 is equipped with a temperature sensor, and the top of the connecting block 8 is equipped with a motor. Before using the device, the staff first installs the energy metering equipment at the front of the mounting component 10. Due to installation requirements, the energy metering equipment is relatively dense and centered to ensure normal operation. During subsequent use, the temperature sensor on the mounting component 10 detects excessively high temperatures and sends an electrical signal to the double-headed electric telescopic rod 7. Upon receiving the signal, the double-headed electric telescopic rod 7 starts, and its telescopic end drives the connecting block 8 to move. The connecting block 8 slides on the inner wall of the guide rod 4. Simultaneously, the connecting block 8 also drives the moving plate 9 to move. The movement of the moving plate 9 drives the mounting component 10 to move. During the movement of the mounting component 10, it simultaneously drives the energy metering equipment to move. After the energy metering equipment has moved a certain distance, it disperses the energy metering equipment, preventing heat accumulation between them during use. This allows for temperature control of the energy metering equipment and cooling of the interior of the housing 1, improving the temperature control effect of the device. The reciprocating lead screw 11 is fixedly connected to the output end of the motor. The connecting block 8 is slidably connected to the inner wall of the guide rod 4. The limiting block 13 is slidably connected to the inner wall of the housing 1, and the limiting block 13 is used to provide movement limiting guidance for the movable block 12. The cooling nozzle 14 is connected to the connecting air pipe 15. The connecting air pipe 15 is in contact with the housing 1 and is connected to the filter fan. When the device is in use, during the lateral movement of the connecting block 8, the movement of the connecting block 8 synchronously drives the reciprocating lead screw 11 to move. Simultaneously, the activation of the double-headed electric telescopic rod 7 sends an electrical signal to the motor. Upon receiving the signal, the motor starts synchronously, and its output drives the reciprocating lead screw 11 to rotate. The rotation of the reciprocating lead screw 11 drives the movable block 12 to move. At this time, the movable block 12 also drives the limiting block 13 to move. Because the limiting block 13 slides against the inner wall of the housing 1, the limiting block 13, while the reciprocating lead screw 11 is rotating, causes the movable block... 12 can only move up and down through the reciprocating groove on the surface of the reciprocating screw 11. The movement of the movable block 12 will drive the cooling nozzle 14 to move. The movement of the cooling nozzle 14 will drive the connecting air pipe 15 to move. After moving a certain distance, the cooling nozzle 14 can be located at the rear of the separately overheated power metering device. At this time, the filter fan can discharge the cooling gas into the cooling nozzle 14 through the connecting air pipe 15, and discharge it to the rear of the power metering device through the cooling nozzle 14. This allows for separate temperature control of the overheated power metering device, improving the monitoring and temperature control effect of the device. Overall working principle: It can disperse the electricity metering equipment to avoid the phenomenon of heat accumulation between the electricity metering equipment during use, and can control the temperature of the electricity metering equipment and cool the inside of the box 1, thereby improving the temperature control effect of the device. The filter fan can discharge cooling gas into the cooling nozzle 14 through the air pipe 15, and then discharge it to the rear of the electricity metering equipment through the cooling nozzle 14. It can individually control the temperature of the overheated electricity metering equipment, thereby improving the monitoring and temperature control effect of the device.

[0022] like Figures 1-8 As shown, based on the above embodiment, the ventilation mechanism 5 includes a diversion plate 501, which is fixedly connected to the circumferential surface of the cooling nozzle 14. A transverse jet plate 502 is fixedly connected to the front of the moving plate 9, and a connecting pipe 503 is fixedly connected to the circumferential surface of the diversion plate 501. During use, as the cooling nozzle 14 moves up and down, it simultaneously drives the diversion plate 501 to move. The up and down movement of the diversion plate 501 also drives the connecting pipe 503 to move. After the connecting pipe 503 has moved a certain distance, it will contact the horizontal jet plate 502 and become interconnected. At this time, a portion of the gas in the cooling nozzle 14 will be diverted by the diversion plate 501 and enter the connecting pipe 503. The connecting pipe 503 can then connect with the horizontal jet plate 502, allowing it to discharge the diverted cooling gas into the horizontal jet plate 502. The horizontal jet plate 502 can then discharge the cooling gas from both sides of the energy metering device and bring the cooling gas into contact with the energy metering device, thereby expanding the temperature control range of the energy metering device and improving the temperature control effect of the energy metering box. The ventilation mechanism 5 also includes a fixing block 504, which is fixedly connected to the right side of the connecting block 8. A fixing cover 505 is fixedly connected to the inner wall of the housing 1. A second ventilation plate 506 is slidably connected to the inner wall of the fixing cover 505. A guide inclined block 507 is fixedly connected to the left side of the second ventilation plate 506. A guide plate 508 is fixedly connected to the inner wall of the housing 1. A slider 509 is slidably connected to the inner wall of the guide plate 508. A roller 510 is rotatably connected to the inner wall of the slider 509. A connecting rod 511 is rotatably connected to the inner wall of the slider 509. A vent plate 512 is fixedly connected to the inner wall of the fixing cover 505. The diverter plate 501 and the cooling nozzle 1 are also connected. 4. The diversion plate 501 is connected to the connecting pipe 503. The connecting pipe 503 is in contact with the transverse jet plate 502 and the moving plate 9. The guide block 507 is located on the movement trajectory of the roller 1 510. A return spring is provided between the ventilation plate 2 506 and the fixed cover 505. The connecting rod 511 is rotatably connected to the inner wall of the fixed block 504. The ventilation plate 512 is located on the movement trajectory of the ventilation plate 2 506. Ventilation holes are provided on the ventilation plate 2 506. When the ventilation plate 2 moves to the underside of the ventilation plate 512, its ventilation holes are connected to the ventilation plate, and outside air can enter the box 1 through the ventilation plate 512. When the device is in use, as the connecting block 8 moves, the movement of the connecting block 8 synchronously drives the connecting rod 511 to move. During the movement of the connecting rod 511, the connecting rod 511 will synchronously adjust its angle. During the angular rotation of the connecting rod 511, the connecting rod 511 will synchronously drive the slider 509 to move. At this time, the slider 509 will slide on the inner wall of the guide plate 508. The movement of the slider 509 will synchronously drive the first roller 510 to move. After moving a certain distance, the first roller 510... It will contact the inclined surface of the guide inclined block 507 and push the guide inclined block 507 to move through the pressure of the inclined surface of the guide inclined block 507. The movement of the guide inclined block 507 will drive the second ventilation plate 506 to move. After moving a certain distance, the second ventilation plate 506 will move on the inner wall of the fixed cover 505. Then the second ventilation plate 506 will be located on the lower right side of the ventilation plate 512. At this time, the outside air can enter the box 1 through the ventilation plate 512, which can improve the ventilation effect of the box 1 and improve the temperature control efficiency of the device. The protective mechanism 6 includes a mounting base 601, which is fixedly connected to the top of the fixed cover 505. A protective inclined plate 602 is rotatably connected to the circumferential surface of the mounting base 601. A sealing plate 603 is slidably connected to the inner wall of the protective inclined plate 602. A ratchet limiting mechanism is provided between the mounting base 601 and the protective inclined plate 602. The protective inclined plate can adjust its angle around the mounting base 601 within a certain range and is fixed in a set position by ratchet self-locking. During the use of the device, the operator can manually rotate and limit the angle of the protective inclined plate 602 until it is at a suitable angle. During the rotation of the protective inclined plate 602, the rotation of the protective inclined plate 602 will drive the sealing plate 603 to rotate. At this time, the sealing plate 603 can keep itself in contact with the box 1 through the spring. At this time, the sealing plate 603 and the protective inclined plate 602 can protect the ventilation and heat dissipation parts of the box 1, which can prevent external debris from falling and contacting the ventilation and heat dissipation parts, thereby causing damage to the parts and improving the service life of the device. The protective mechanism 6 also includes an L-block 604, which is fixedly connected to the right side of the ventilation plate 506. A roller 605 is rotatably connected to the inner wall of the L-block 604. A reciprocating screw 606 is fixedly connected to the front of the roller 605. A movable rod 607 is movably connected to the circumferential surface of the reciprocating screw 606. A scraper 608 is fixedly connected to the left side of the movable rod 607. A limit post 609 is fixedly connected to the front of the L-block 604. A sealing plate 603 is in contact with the housing 1. A spring is connected between the sealing plate 603 and the protective inclined plate 602. The roller 605 is in contact with the ventilation plate 512. The movable rod 607 is slidably connected to the circumferential surface of the limit post 609. The scraper 608 is in contact with the ventilation plate 506. When the device is in use, the ventilation plate 506 moves, which synchronously moves block L 604. During this movement, block L 604 moves roller 605. As roller 605 moves, friction is generated due to its contact with the ventilation plate 512, causing roller 605 to rotate. This rotation of roller 605 drives the reciprocating screw 606 to rotate, which in turn drives the movable rod 607. During the movement, the limiting post 609 causes the scraper 608 to move laterally through the reciprocating groove on the surface of the reciprocating screw 606 as the scraper 608 rotates. The lateral movement of the movable rod 607 will drive the scraper 608 to move synchronously. During the movement, the scraper 608 can scrape and push the dust and debris on the surface of the ventilation plate 506, which can ensure the ventilation stability of the ventilation plate 506, avoid blockage, and thus improve the temperature control effect of the device. Overall working principle: It can discharge cooling gas from both sides of the power metering equipment and make the cooling gas contact with the power metering equipment, which can expand the temperature control range of the power metering equipment, thereby improving the temperature control effect of the power metering box, improving the ventilation effect of the box 1, improving the temperature control efficiency of the device, protecting the ventilation and heat dissipation parts of the box 1, preventing external debris from falling and contacting the ventilation and heat dissipation parts, thus preventing damage to the parts, extending the service life of the device, ensuring the ventilation stability of the second ventilation plate 506, preventing blockage, and thus improving the temperature control effect of the device.
