Description

Technical Field

[0001] This utility model relates to the field of electricity meter technology, specifically to a remote prepaid smart electricity meter. Background Technology

[0002] With social development, technological advancements, and the continuous improvement of national infrastructure, power facilities are becoming increasingly intelligent. Electricity meters, as specialized instruments for measuring electrical energy, are broadly classified into two categories based on their operating principles: induction and electronic. Smart meters, serving as intelligent terminals in the smart grid, are no longer traditional electricity meters. Besides possessing the basic electricity metering function of traditional meters, smart meters, to adapt to the smart grid and the use of new energy sources, also feature bidirectional multi-rate metering, user-end control functions, and bidirectional data communication functions with multiple data transmission modes. In contrast, existing remote-controlled smart meters are typically installed on the inner wall of the meter box using screws or bolts. Installation and maintenance personnel need tools to install or remove the meters, making the operation cumbersome and inconvenient. Utility Model Content

[0024] Example 1

[0025] An embodiment of this utility model provides a remote prepaid smart energy meter, such as... Figures 1-4As shown, the device includes a mounting plate 1 and an electricity meter body 5. The electricity meter body 5 is mounted on the mounting plate 1. The mounting plate 1 is provided with a U-shaped clamping plate 4 and a transverse limiting plate 2. The U-shaped clamping plate 4 is positioned above the transverse limiting plate 2. L-shaped plates 6 are provided on both the left and right sides of the electricity meter body 5. The mounting plate 1 is provided with symmetrical clamping frames 11 for clamping the L-shaped plates 6. The mounting plate 1 is also provided with a pressing mechanism for pressing the upper surface of the electricity meter body 5. The electricity meter body 5 passes through the U-shaped clamping plate 4 and contacts the transverse limiting plate 2. A remote communication module is provided inside the electricity meter body 5.

[0026] The working principle and beneficial effects of the above technical solution are as follows: The electricity meter body 5 is tightly attached to the mounting plate 1, and then the electricity meter body 5 is moved downward. The electricity meter body 5 passes through the U-shaped clamping plate 4 and then contacts the transverse limiting plate 2. The U-shaped clamping plate 4 clamps the electricity meter body 5. At this time, two L-shaped plates 6 are inserted into the clamping frame 11, and the clamping frame 11 clamps the L-shaped plates 6. Then, the squeezing mechanism is activated to further restrict the position of the electricity meter body 5. When replacing the electricity meter body 5, the squeezing mechanism is activated first, and the electricity meter body 5 can be pulled out. The position of the electricity meter body 5 can be effectively limited by the U-shaped clamping plate 4, the squeezing mechanism, and the transverse limiting plate 2. At the same time, the clamping frame 11 further restricts the position of the electricity meter body 5 by clamping the L-shaped plates 6. Moreover, the entire device does not require the use of bolts, screws, or other connecting parts for connection. The installation and replacement of the electricity meter body 5 are more convenient and more practical.

[0027] Example 2

[0028] Based on the above embodiment 1, as follows Figures 1-4 The extrusion mechanism shown includes a fixed plate 9, a threaded rod 10 is provided through the fixed plate 9, the threaded rod 10 is threadedly connected to the fixed plate 9, a rotating wheel 8 is fixedly provided at the upper end of the threaded rod 10, and an extrusion plate 7 is rotatably connected to the lower end of the threaded rod 10. The extrusion plate 7 is slidably connected to the mounting plate 1 and cooperates with the upper end of the energy meter body 5.

[0029] Preferably, the U-shaped clamping plate 4 includes two connecting plates 402 and a horizontal plate 401. The connecting plates 402 are fixedly connected to the mounting plate 1. A clamping block 12 is slidably arranged on the side of the two connecting plates 402 that are close to each other. Several springs 13 are fixedly arranged on the clamping block 12. The springs 13 are fixedly connected to the horizontal plate 401.

[0030] Preferably, the electricity meter body 5 is in contact with the two connecting plates 402 and the clamping block 12, and the upper end of the clamping block 12 is provided with an arc-shaped part 14 on the side near the mounting plate 1.

[0031] The working principle and beneficial effects of the above technical solution are as follows: Rotating the wheel 8 drives the threaded rod 10 to rotate, thereby causing the threaded rod 10 and the wheel 8 to move downward together. The threaded rod 10 pushes the pressing plate 7 to move downward, and the pressing plate 7 will press the energy meter body 5. Similarly, when it is necessary to remove the energy meter body 5, the wheel 8 can be rotated in the opposite direction.

[0032] When the electricity meter body 5 is inserted into the U-shaped clamping plate 4, the electricity meter body 5 will first contact the arc-shaped part 14 at the upper end of the clamping block 12, so that the clamping block 12 can be easily pushed open and several springs 13 are compressed. At the same time, the electricity meter body 5 contacts the two connecting plates 402. As the electricity meter body 5 continues to move, the clamping block 12 clamps the electricity meter body 5 under the action of several springs 13. Thus, the electricity meter body 5 is limited in the front-back and left-right directions. With the cooperation of the compression plate 7, it can also be limited on the upper side. The structure is simple, easy to use, and more practical.

[0033] Example 3

[0034] Based on the above embodiments 1-2, such as Figure 1 As shown, the lower end of the electricity meter body 5 is connected to several ribbon cables, and several through holes 3 are provided on the horizontal limiting plate 2, through which the ribbon cables pass.

[0035] The beneficial effects of the above technical solution are as follows: by setting the horizontal limiting plate 2, the position of the electricity meter body 5 can be restricted from the bottom; and by setting several through holes 3, the connection of several ribbon cables can be made more convenient and more practical.

[0036] Example 4

[0037] Based on the above embodiment 1, as follows Figures 1-4 As shown, a wedge block 17 is provided inside the clamping frame 11. The wedge block 17 slides out of the clamping frame 11 from the side wall away from the electricity meter body 5. A wedge part 16 is provided at the lower end of the L-shaped plate 6. The wedge part 16 cooperates with the wedge block 17.

[0038] Preferably, the clamping frame 11 is a hollow cube with openings at the top and bottom.

[0039] Preferably, the L-shaped plate 6 has a wedge-shaped groove 15, which cooperates with the wedge block 17. A reset plate 19 is fixedly installed on the side of the wedge block 17 away from the electricity meter body 5. A second spring 18 is sleeved on the wedge block 17. One end of the second spring 18 is fixedly connected to the reset plate 19, and the other end of the second spring 18 is fixedly connected to the clamping frame 11.

[0040] Preferably, the L-shaped plate 6 is provided with a through hole, and the clamping frame 11 is also provided with a limiting rod 21. The clamping frame 11 is provided with a limiting hole on the side wall away from the electricity meter body 5. The limiting rod 21 extends out of the clamping frame 11 through the limiting hole. A pull plate 20 is fixedly provided on the side of the limiting rod 21 away from the electricity meter body 5. The limiting rod 21 cooperates with the through hole.

[0041] Preferably, a placement ring 22 is fixedly provided on the reset plate 19.

[0042] The working principle and beneficial effects of the above technical solution are as follows: When the L-shaped plate 6 is inserted into the clamping frame 11, the wedge-shaped part 16 at the lower end of the L-shaped plate 6 will first contact the wedge block 17, thereby pushing the wedge block 17 open. The wedge block 17 drives the reset plate 19 to move, the second spring 18 is stretched, and then the L-shaped plate 6 continues to move downward. Under the action of the second spring 18, the reset plate 19 is reset, and the wedge block 17 will be inserted into the wedge groove 15 (a clicking sound will be heard). At this time, the limiting rod 21 is taken out, the limiting rod 21 is passed through the limiting hole, and the pull plate 20 is pushed so that the limiting rod 21 passes through the through hole, thereby limiting the position of the L-shaped plate 6. Similarly, when it is necessary to replace the energy meter body 5, the pull plate 20 is pulled first to pull out the limiting rod 21, and then the placement ring 22 is pulled so that the wedge block 17 no longer cooperates with the wedge groove 15.

[0043] The above-mentioned mechanism effectively supplements the clamping and limiting of the electricity meter body 5 by the U-shaped clamping plate 4, the squeezing plate 7 and the transverse limiting plate 2. It can also reduce the shaking of the electricity meter body 5. In addition, the placement ring 22 can be set to place several ribbon cables and can also facilitate the movement of the reset plate 19, making it more practical.

[0044] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
