Description

Technical Field

[0001] This utility model belongs to the field of electricity meter technology, specifically a low-power single-phase smart electricity meter. Background Technology

[0002] Smart meters are an upgraded version of traditional mechanical meters, integrating microelectronics, computer technology, and communication technology. They can not only accurately measure electricity consumption, but also have functions such as data storage, remote communication, and anomaly monitoring. They are the core terminal equipment for building a smart grid.

[0003] Low-power single-phase smart energy meters are specialized products designed for "single-phase power consumption scenarios." While retaining the core functions of single-phase smart energy meters, they focus on optimizing "power consumption control," making them particularly suitable for power-sensitive scenarios.

[0004] Through long-term observation, it was found that because the electricity meter itself lacks an auxiliary positioning structure, it requires the cooperation of two operators to align and fix it with the preset mounting holes in the distribution cabinet. This two-person installation mode not only significantly increases the labor cost, but also easily leads to slight displacement of the electricity meter in actual operation due to problems such as inconsistent rhythm of personnel cooperation and uneven hand strength. Therefore, a low-power single-phase smart electricity meter is proposed to address the above problems. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing technology and solve at least one of the technical problems mentioned in the background technology, this utility model proposes a low-power single-phase smart energy meter.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A low-power single-phase smart energy meter of this utility model includes a meter housing, a plurality of mounting parts are fixedly connected to the side wall of the meter housing, and a slot is opened on the outer wall of the meter housing; characterized in that: a connecting seat is provided on the top of the meter housing, two sliding pins are slidably connected inside the connecting seat, a support plate is fixedly connected to the ends of the two sliding pins, a plurality of positioning suction cups are fixedly connected to the outer wall of the support plate for adsorbing onto the inner wall of the distribution cabinet, and a gripping frame is fixedly connected to the other end of the two sliding pins.

[0007] Preferably, the outer wall of the meter housing has two sliding grooves, which are located on both sides of the card slot. A sealing plate is slidably connected to the outer wall of the meter housing through the two sliding grooves. An extension frame is fixed to the bottom of the sealing plate. A limit slot is provided at the bottom of the extension frame for locking the side wall of the electric card.

[0008] Preferably, both ends of the meter housing are fixedly connected to a fixed base, and a movable groove is opened through the inside of the fixed base. A sliding plate is slidably connected inside the fixed base through the movable groove. The sliding plate is fixedly connected to the connecting base, and the sliding plate is detachably installed inside the fixed base.

[0009] Preferably, a magnetic plate is fixedly connected inside the fixing seat, and a metal sheet is fixedly connected to the bottom of the connecting seat, wherein the magnetic plate and the metal sheet are attracted to each other.

[0010] Preferably, a counterweight is fixed to the top of the extension frame.

[0011] Preferably, the sliding pin has a square structure.

[0012] The beneficial effects of this utility model are: This utility model provides a low-power single-phase smart energy meter. The initial positioning of the meter by the positioning suction cup can replace manual hand-holding and fixing. The operator does not need one person to hold the meter and another to tighten the bolts. The bolt installation can be completed by one person alone, reducing the need for manpower cooperation, shortening the installation time, and avoiding meter displacement caused by unstable hand-holding. It also ensures that the mounting parts are accurately aligned with the mounting holes of the distribution cabinet, reducing the difficulty of bolt installation.

[0013] This utility model provides a low-power single-phase smart energy meter. By using a baffle plate, it can isolate external impurities and avoid the problem of unused card slots being directly exposed to the outside world. The card slot limits the card and prevents the card from shifting left or right due to vibration of the power distribution cabinet or accidental touch by personnel, ensuring continuous data transmission and avoiding recharge interruption or loss of metering data.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Specific implementation examples are given below.

[0018] like Figure 1-4 As shown, the device includes a meter housing 1, with multiple mounting parts 11 fixed to the side wall of the meter housing 1, and a slot 12 on the outer wall of the meter housing 1. The device is characterized by: a connecting seat 13 at the top of the meter housing 1, with two sliding pins 14 slidably connected inside the connecting seat 13; a support plate 15 fixed to the ends of the two sliding pins 14; multiple positioning suction cups 16 fixed to the outer wall of the support plate 15 for adhering to the inner wall of the distribution cabinet; and a gripping frame 17 fixed to the other end of the two sliding pins 14. During operation, the operator holds the gripping frame 17 and pushes the sliding pins 14 towards the inner wall of the distribution cabinet. Because the sliding pins 14 are slidably connected to the connecting seat 13, they can drive the support plate 15 to move synchronously until the positioning suction cups 16 are in close contact with the inner wall of the distribution cabinet. The positioning suction cups 16 create negative pressure by squeezing out internal air, thus holding the support plate 15 in place. The suction cup 15 adheres to the inner wall of the distribution cabinet, thus maintaining the meter housing 1 in a stable temporary position and completing the initial positioning. If the position is deviated, the gripping bracket 17 is pulled in the opposite direction to release the negative pressure of the suction cup, and the suction cup can be re-adsorbed after adjustment. After confirming that the meter position is correct after initial positioning, the bolt is passed through the mounting part 11 on the side wall of the meter housing 1 and screwed into the preset mounting hole or fixing bracket of the distribution cabinet. The mechanical tightening force of the bolt completely fixes the meter housing 1 to the distribution cabinet, forming a long-term stable installation state. This step can replace manual hand-holding and fixing in the initial positioning of the positioning suction cup 16. The operator does not need one person to hold the meter and another to tighten the bolt. The bolt installation can be completed by one person alone, reducing the need for manpower cooperation, shortening the installation time, and avoiding meter displacement caused by unstable hand holding. It ensures that the mounting part 11 is accurately aligned with the mounting hole of the distribution cabinet and reduces the difficulty of bolt installation.

[0019] like Figure 1-4As shown, the outer wall of the meter housing 1 has two sliding grooves 2, which are located on both sides of the card slot 12. A sealing plate 21 is slidably connected to the outer wall of the meter housing 1 through the two sliding grooves 2. An extension frame 22 is fixed to the bottom of the sealing plate 21. A limit slot 23 is provided at the bottom of the extension frame 22 for locking the side wall of the card 100. Before inserting the card 100, the sealing plate 21 can be pushed upward along the sliding groove 2 to disengage it from the card slot 12. After the card slot 12 is exposed, the card 100 can be inserted to complete the recharge or data transfer. After the electricity card 100 is inserted, the sealing plate 21, which slides downward along the sliding groove 2, can lock the exposed side wall of the electricity card 100 into the limiting card slot 23. The limiting card slot 23 restricts the lateral displacement of the electricity card 100 through physical locking. Under the action of the sealing plate 21, external impurities can be isolated, avoiding the problem of the card slot 12 being directly exposed to the outside when not in use. The limiting card slot 23 fixes the electricity card 100, preventing the electricity card 100 from shifting left or right due to the vibration of the power distribution cabinet or accidental touch by personnel, ensuring continuous data transmission and avoiding recharge interruption or loss of metering data.

[0020] like Figure 1-4 As shown, both ends of the meter housing 1 are fixedly connected to a fixed base 3. A movable groove 31 is formed inside the fixed base 3, and a sliding plate 32 is slidably connected to the fixed base 3 through the movable groove 31. The sliding plate 32 is fixedly connected to the connecting base 13, but is detachable within the fixed base 3. During the initial positioning stage, if the suction position of the positioning suction cup 16 needs to be adjusted, the connecting base 13 can be pushed or pulled. The connecting base 13 causes the sliding plate 32 to slide along the movable groove 31 of the fixed base 3, thereby adjusting the position of the positioning suction cup 16. In the lateral position of 6, if the meter is fixed with bolts, the slide plate 32 can be pulled out from the fixed base 3 along the movable groove 31, and the positioning components such as the connecting base 13 and the sliding pin 14 can be removed. Only the meter housing 1 and the mounting part 11 are left to be fixed with bolts. This step improves the flexibility of fixing the meter housing 1 by adjusting the position of the slide plate 32 to fit different areas in the distribution cabinet. When the positioning suction cup 16 or the sliding pin 14 is damaged, it is not necessary to replace the entire meter. The positioning components can be repaired or replaced separately by disassembling the slide plate 32, thus avoiding waste of resources.

[0021] like Figure 1-4 As shown, a magnetic plate 4 is fixedly connected inside the fixed base 3, and a metal sheet 41 is fixedly connected to the bottom of the connecting base 13. The magnetic plate 4 and the metal sheet 41 are attracted to each other. When the sliding plate 32 drives the connecting base 13 to slide along the movable groove 31 to the target position, the metal sheet 41 at the bottom of the connecting base 13 contacts the magnetic plate 4 in the fixed base 3 and generates a magnetic attraction, temporarily fixing the connecting base 13 in the current position to prevent it from sliding along the movable groove 31 during bolt installation. The magnetic fixation provides additional positional constraints for the connecting base 13, reduces the meter offset during bolt installation, and ensures stable connection between the mounting part 11 and the bolt hole.

[0022] like Figure 1-4 As shown, a counterweight 5 is fixedly connected to the top of the extension frame 22. When the baffle 21 slides, the extension frame 22 moves synchronously along the sliding groove 2 with the baffle 21. The weight of the counterweight 5 keeps the extension frame 22 in a downward trend. The weight of the counterweight 5 is transmitted to the limiting slot 23 through the extension frame 22, which increases the fixing force of the limiting slot 23 on the electric card 100, prevents the electric card 100 from falling off when the power distribution cabinet vibrates, and ensures that the electric card 100 is in stable contact with the card slot 12.

[0023] like Figure 1-4 As shown, the sliding pin 14 is a square structure; the four sides of the square sliding pin 14 are tightly fitted with the inner wall of the connecting seat 13, with a larger contact area, avoiding the displacement of the support plate 15 caused by vibration or external force rotation of the traditional round sliding pin 14. The anti-rotation design can prevent the positioning suction cup 16 from shifting, ensuring that the mounting part 11 is accurately positioned after the meter housing 1 is initially positioned.

[0024] Working principle: The operator holds the grip 17 and pushes the sliding pin 14 towards the inner wall of the distribution cabinet. Because the sliding pin 14 is slidably connected to the connecting seat 13, it drives the support plate 15 to move synchronously until the positioning suction cup 16 makes tight contact with the inner wall of the distribution cabinet. The positioning suction cup 16 creates negative pressure by squeezing out internal air, adsorbing the support plate 15 onto the inner wall of the distribution cabinet, thus maintaining the meter housing 1 in a stable temporary position, completing the initial positioning. If the position is deviated, the grip 17 is pulled in the opposite direction to release the negative pressure of the suction cup, and the suction cup is re-adsorbed after adjustment. After confirming that the meter position is correct during the initial positioning... Using bolts, the mounting parts 11 are passed through the side wall of the meter housing 1 and screwed into the pre-set mounting holes or fixing brackets of the distribution cabinet. The mechanical tightening force of the bolts completely fixes the meter housing 1 to the distribution cabinet, forming a long-term stable installation. Before inserting the card 100, the sealing plate 21 can be pushed upwards along the sliding groove 2 to disengage it from the card slot 12, exposing the card slot 12. Then, the card 100 can be inserted to complete the recharge or data reading. After the card 100 is inserted, the sealing plate 21, which slides downwards along the sliding groove 2, can engage the exposed side wall of the card 100 into the limiting slot 23. 23. By physically locking the lateral displacement of the electric meter 100, during the initial positioning stage, if it is necessary to adjust the adsorption position of the positioning suction cup 16, the connecting seat 13 can be pushed or pulled. The connecting seat 13 drives the sliding plate 32 to slide along the movable groove 31 of the fixed seat 3, thereby adjusting the lateral position of the positioning suction cup 16. If the electric meter is fixed with bolts, the sliding plate 32 can be pulled out from the fixed seat 3 along the movable groove 31, and the positioning components such as the connecting seat 13 and the sliding pin 14 can be removed, leaving only the electric meter housing 1 and the mounting part 11 for bolt fixing. When the sliding plate 32 drives the connecting seat 13 to slide along the movable groove 31 to the desired position, the lateral position of the positioning suction cup 16 can be adjusted. After reaching the target position, the metal plate 41 at the bottom of the connecting seat 13 contacts the magnetic plate 4 inside the fixed seat 3 and generates a magnetic attraction, temporarily fixing the connecting seat 13 in the current position to prevent it from sliding along the movable groove 31 during bolt installation. When the sealing plate 21 slides, the extension frame 22 moves synchronously along the sliding groove 2 with the sealing plate 21. The weight of the counterweight 5 keeps the extension frame 22 always in a downward trend. The four sides of the square sliding pin 14 fit tightly against the inner wall of the connecting seat 13, with a larger contact area, preventing the support plate 15 from shifting due to vibration or external force rotation caused by the traditional round sliding pin 14.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
