Description

Technical Field

[0001] This utility model belongs to the field of electricity meter technology, and specifically relates to a high-voltage electricity meter. Background Technology

[0002] An electricity meter is an instrument used to measure electrical energy; it is also called a kilowatt-hour meter, a power meter, or a kilowatt-hour meter, and refers to instruments that measure various electrical quantities. A high-voltage electricity meter is a metering device used to directly measure electrical energy in high-voltage power systems and is widely used in 10kV and 35kV distribution networks. When an electricity meter malfunctions, maintenance personnel need to open the meter casing to remove it. However, the gap between the electricity meter and the casing is generally small, making it inconvenient for maintenance personnel to operate. Therefore, there is an urgent need for a high-voltage electricity meter.

[0003] A patent with publication number CN218350352U discloses a multi-functional energy meter, which includes an energy meter body, a rotating shaft, a driving bevel gear, a driven bevel gear, an adjusting rod, a sprocket, and a chain. When the energy meter body needs to be inspected, the rotating shaft is rotated, and the meshing of the driving bevel gear and the driven bevel gear causes the adjusting rod connected to the driven bevel gear to rotate. At the same time, the driven bevel gear also drives the other adjusting rods to rotate through the transmission cooperation of the sprocket and the chain, so that several adjusting rods rotate synchronously, thereby removing the energy meter body from the meter case.

[0004] However, the above solution can only rotate the shaft after the box door is fully opened, which is not convenient to operate and undoubtedly increases the difficulty and time cost of operation. It cannot quickly remove the electricity meter body from the casing, so the practical effect is generally poor. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0024] like Figures 1-4 As shown, the technical solution adopted by this utility model is as follows: A high-voltage energy meter includes a protection box 1, one side of which is open. A door 2 is rotatably mounted on the open side of the protection box 1 via a connecting rod 3. The door 2 is fixedly connected to the connecting rod 3, and the connecting rod 3 is rotatably connected to the protection box 1. (It should be noted that a locking mechanism is provided between the door 2 and the protection box 1 to achieve the closing of the door 2. Any locking mechanism available on the market that can be used for the door 2 is suitable for this solution and will not be described in detail.)

[0025] The protective box 1 has a limit sliding installation of a placement plate 8, on which the energy meter body 16 is placed and a clamping mechanism acting on the energy meter body 16 is provided; the connecting rod 3 is driven to the placement plate 8 through a first transmission component, and the placement plate 8 is driven to the clamping mechanism through a second transmission component.

[0026] Furthermore, a sliding groove is opened on the bottom inner wall of the protective box 1, and a limiting plate 7 is slidably installed in the sliding groove. The top of the limiting plate 7 is fixedly connected to the placement plate 8, and a connecting post 18 is fixedly installed at the bottom of the limiting plate 7.

[0027] The first transmission component includes a belt 5. A placement groove is opened at the bottom of the protective box 1. The bottom of the connecting rod 3 extends rotatably into the placement groove and a pulley (not marked in the figure) is fixedly installed. A rotating plate 4 is rotatably installed in the placement groove. A sliding column 19 is fixedly and eccentrically installed at the top of the rotating plate 4. A pulley is fixedly installed at the bottom of the rotating plate 4. A belt 5 is sleeved between the two pulleys. In addition, a slotted plate 6 is rotatably installed in the placement groove. The slotted plate 6 has a first mating groove 20 that is in transmission with the sliding column 19 and a second mating groove 21 that is in transmission with the connecting column 18.

[0028] Opening the door 2 will cause the connecting rod 3 to rotate. With the help of the pulley and belt 5, the rotating plate 4 will rotate. The rotating plate 4 will drive the sliding column 19 to rotate around the central axis of the rotating plate 4. Thus, under the sliding engagement of the sliding column 19 and the first mating groove 20, the slot plate 6 will rotate. Then, with the help of the sliding engagement of the second mating groove 21 and the connecting column 18 (the two do not disengage), the placement plate 8 will be pushed to slide out of the protective box 1.

[0029] The clamping mechanism includes a movable plate 13. A limiting groove (not marked in the figure) is opened on the top of the placement plate 8. Two movable plates 13 are slidably arranged in the limiting groove and are arranged facing each other. A second spring 17 is provided between the opposite sides of the two movable plates 13 and the limiting groove. A fixed plate 15 is connected to the opposite sides of the two movable plates 13 through an elastic element.

[0030] Furthermore, the elastic element includes a first spring 14, which is provided between the movable plate 13 and the fixed plate 15. One end of the first spring 14 is fixedly connected to the movable plate 13, and the other end is fixedly connected to the fixed plate 15. A telescopic rod (not shown in the figure) is provided inside the first spring 14. The first spring 14 is sleeved on the outer surface of the telescopic rod, and one end of the telescopic rod is fixedly connected to the movable plate 13, and the other end is fixedly connected to the fixed plate 15.

[0031] The second transmission component includes a toothed plate 11, which is fixedly installed on both inner walls of the protective box 1. A mating rod 12 is fixedly installed at the bottom of each of the two movable plates 13. A rotating shaft 22 is rotatably installed through both inner walls of the placement plate 8. Gears 10 are fixedly installed on opposite sides of the two rotating shafts 22, and inclined blocks 9 are fixedly installed on opposite sides of the two rotating shafts 22. The gears 10 mesh with the toothed plates 11 in a one-to-one correspondence, and the inclined blocks 9 engage with the mating rods 12 in a one-to-one correspondence.

[0032] Working principle: When the electricity meter body 16 needs to be inspected, the door 2 is opened. During the opening process, the connecting rod 3 will rotate. With the transmission of the pulley and belt 5, the rotating plate 4 will rotate. The rotating plate 4 will drive the sliding column 19 to rotate around the central axis of the rotating plate 4. Thus, under the sliding engagement of the sliding column 19 and the first mating groove 20, the slot plate 6 will rotate. Then, with the sliding engagement of the second mating groove 21 and the connecting column 18 (the two do not disengage), the placement plate 8 will be pushed to slide out of the protection box 1, so that the electricity meter body 16 will slide out of the protection box 1.

[0033] As the placement plate 8 slides towards the protective box 1, the meshing of the toothed plate 11 and the gear 10 causes the rotating shaft 22 to rotate, which in turn drives the inclined block 9 to rotate synchronously. With the pull of the second spring 17, the cooperating rod 12 remains in contact with the inclined surface of the inclined block 9 during its rotation, causing the two moving plates 13 to move away from each other, thereby causing the two fixed plates 15 to move away from each other and releasing the restriction on the electricity meter body 16. The entire operation is more convenient, easier, and saves time, allowing for quick removal of the electricity meter body 16 and improving its practicality.

[0034] When the maintenance is completed and the electricity meter body 16 needs to be put back, place the electricity meter body 16 on the placement plate 8 so that the electricity meter body 16 is located between the two fixed plates 15. Close the door 2 so that the two moving plates 13 move closer to each other. Then, the first spring 14 pushes the two fixed plates 15 closer to each other to clamp and limit the electricity meter body 16.

[0035] At the same time, the connecting rod 3 will also drive the placement plate 8 to slide into the protection box 1 under the transmission cooperation of the first transmission component, so that the placement plate 8 is reset and the electricity meter body 16 is located in the protection box 1, so as to better protect the electricity meter body 16.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
