Description

Technical Field

[0001] This utility model belongs to the field of electricity meter testing technology, specifically relating to a meter holder for testing single-phase electricity meters that is compatible with both State Grid and China Southern Power Grid. Background Technology

[0002] In power systems, single-phase energy meters are crucial devices for measuring energy consumption, and their testing is of paramount importance. State Grid and China Southern Power Grid, as my country's two major power suppliers, have certain differences in their testing standards and requirements for single-phase energy meters (differences exist in the height of the auxiliary needles and the positions of two of the auxiliary needles).

[0003] Currently, the testing of single-phase electricity meters for the State Grid and China Southern Power Grid typically requires the use of different meter holders to meet their respective testing needs. This approach presents several problems. On the one hand, the need for multiple meter holders increases testing costs and the complexity of equipment management; on the other hand, changing meter holders during the testing process not only wastes time but also reduces testing efficiency.

[0004] Existing single-phase energy meter testing bases also have structural design deficiencies. The moving drive structure of the base is not flexible enough, which may cause jamming during movement, affecting the accuracy and stability of the test. The design of the auxiliary needle module is also difficult to meet the testing requirements of both the State Grid and the Southern Power Grid. For example, the contact between the auxiliary needle and the energy meter is not stable enough, which can easily cause testing errors. Utility Model Content

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a meter holder compatible with single-phase energy meter testing of State Grid and Southern Power Grid, including a meter holder fixing plate, a meter holder, and an auxiliary needle module. The meter holder is installed on the meter holder fixing plate and is driven to move on the meter holder fixing plate by a lower moving drive structure. Several current rods are installed on one side of the meter holder. The auxiliary needle module includes a movable plate and a flip plate. The movable plate is installed on the meter holder and is driven to move on the meter holder by an upper moving drive mechanism. One side of the flip plate is hinged to the movable plate and the flip plate is driven to rotate by a flipping drive mechanism.

[0019] like Figure 1-4As shown, a meter holder for testing single-phase energy meters compatible with State Grid and China Southern Power Grid includes a meter holder fixing plate 1, a meter holder 2, and an auxiliary needle module. The meter holder 2 is mounted on the meter holder fixing plate 1 and is driven to move on the meter holder fixing plate 1 by a lower moving drive structure. Several current rods 3 are mounted on one side of the meter holder 2. The auxiliary needle module includes a movable plate 4 and a flip plate 5. The movable plate 4 is mounted on the meter holder 2 and is driven to move on the meter holder 2 by an upper moving drive mechanism. One side of the flip plate 5 is hinged to the movable plate 4, and the flip plate 5 is driven by a flipping drive mechanism. The mechanism drives rotation. A number of fixed auxiliary pins 6 are fixedly connected to one side of the flap 5, while a number of movable auxiliary pins 7 are provided on the other side. A limit plate 8 is fixedly connected to the movable plate 4, and the limit plate 8 has a number of inclined guide grooves 9. The movable auxiliary pins 7 correspond one-to-one with the guide grooves 9. The flap 5 has an internal movable chamber 10, which contains a spherical groove 11. One end of the movable auxiliary pin 7 moves through the corresponding guide groove 9, while the other end is located in the movable chamber 10 and fixedly connected to a ball 12, which is placed in the spherical groove 11. The flap 5 rotates relative to the movable plate 4, causing both the movable auxiliary pins 7 and the fixed auxiliary pins 6 to move upwards (2mm). Simultaneously, during this upward movement, the movable auxiliary pin 7 is guided by the guide grooves 9 and moves a certain distance towards the fixed auxiliary pin 6, thus changing the distance between the movable auxiliary pin 7 and the fixed auxiliary pin 6 to adapt to single-phase energy meters in different power grids. The spherical groove 11 consists of two parts, one above the other. The cooperation between the sphere 12 and the spherical groove 11 provides a certain degree of freedom for the movable auxiliary pin 7, allowing the movable auxiliary pin 7 to move in the guide groove 9.

[0020] Furthermore, two parallel sliding rods 13 are fixed on the meter base fixing plate 1. A sliding sleeve 14 is fitted onto each sliding rod 13 and is fixedly connected to the meter base 2. The downward movement drive mechanism includes a first cylinder 15, whose working shaft is fixedly connected to the meter base 2 and is fixed to the meter base fixing plate 1. The first cylinder 15 drives the entire meter base 2 to move, causing the current rod 3, fixed auxiliary needle 6, and movable auxiliary needle 7 to move as a whole and insert into the single-phase energy meter for relevant testing.

[0021] Furthermore, the meter base 2 is provided with several sliding grooves 16, and upper sliding rods 17 are respectively provided in the sliding grooves 16. The upper sliding rods 17 are fixedly connected to the movable plate 4. The upper moving drive mechanism includes a second cylinder 18. The working shaft of the second cylinder 18 is fixedly connected to the movable plate 4. The second cylinder 18 is fixedly installed on the meter base 2. The upper sliding rods 17 and lower sliding rods 13 are arranged parallel to each other. When the single-phase energy meter is an IoT meter, the second cylinder 18 drives the movable plate 4 to move backward (4cm) on the meter base 2, so that the auxiliary needle module moves backward (the fixed auxiliary needle 6 and the movable auxiliary needle 7 are not required when the IoT meter is detected).

[0022] Furthermore, the flipping drive mechanism includes a third cylinder 19, which is fixedly connected to the movable plate 4 via a connecting plate 20. The working shaft of the third cylinder 19 is fixedly connected to a column 21, which has an annular groove 22. The flip plate 5 has a clamping groove 23 through which the column 21 passes. Linkage bars 24 are respectively provided on both sides of the clamping groove 23, and are inserted into the annular groove 22. The linkage bars 24 are fixedly connected to the flip plate 5. The third cylinder 19 is vertically positioned. When the third cylinder 19 operates, the cooperation between the annular groove 22 on the column 21 and the linkage bars 24 on the flip plate 5 causes the flip plate 5 to rotate relative to the movable plate 4 at a certain angle. This causes the fixed auxiliary needle 6 and the movable auxiliary needle 7 to rise simultaneously by a certain distance (usually about 2mm). During the rising process, the movable auxiliary needle 7, due to the action of the guide groove 9, moves a certain distance towards the fixed auxiliary needle 6 (horizontal direction), meeting the detection needs of single-phase energy meters in different power grids.

[0023] Furthermore, a pressure plate 25 is fixedly connected to the flip plate 5. The pressure plate 25 is located above the movable auxiliary needle 7. The pressure plate 25 is provided with several arc-shaped pressure grooves 26, which correspond one-to-one with the movable auxiliary needle 7. As the flip plate 5 rotates, the pressure plate 25 can press down on the movable auxiliary needle 7 during the downward flipping process of the flip plate 5, allowing it to slide in the guide groove 9.

[0024] Furthermore, a terminal 27 is fixedly connected to the current rod 3, and a movable cavity 28 is provided inside the base 2 for one end of the current rod 3 to be movably inserted. A spring 29 is provided inside the movable cavity 28. The current rod 3 is connected to an electric wire through the terminal 27. The spring 29 provides a buffering effect, compensates for mechanical assembly errors, and ensures stable current transmission.

[0025] It is worth mentioning that the technical features such as cylinders involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be adopted using conventional choices in the field, and should not be regarded as the inventive point of this utility model patent.

[0026] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make many modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning or limited experimentation on the basis of the prior art should be within the scope of protection defined by the claims.
