Description

A smart meter withstand voltage testing device Technical Field

[0001] This invention belongs to the field of electricity meter testing technology, specifically a smart electricity meter withstand voltage testing device. Background Technology

[0002] An electricity meter, also known as a kilowatt-hour meter, is an instrument used to measure electrical energy and is a mandatory device for residential electrical circuits. Before leaving the factory, electricity meters undergo testing. A withstand voltage test is an important safety test designed to assess whether the meter can maintain its insulation performance under high voltage, ensuring user safety. By applying a test voltage higher than the normal operating voltage, the test verifies whether the meter's insulation materials, wiring, and structure can withstand voltage surges without breakdown or leakage. Withstand voltage testing is typically performed during production or routine maintenance. The test voltage is selected based on the meter's rated voltage and relevant standards such as IEC and UL, ensuring the meter operates safely and reliably in its intended operating environment.

[0003] A patent application with publication number CN116973715B discloses a voltage withstand testing device for electricity meters. This device can test multiple electricity meters simultaneously. It also uses a tube to move a conductive plate, achieving electrical connection between the voltage withstand testing instrument and the electricity meter. This reduces the risk of electric shock from manual contact. Furthermore, the conductive plate makes contact with the fixed points on the electricity meter's wires, ensuring testing accuracy. Additionally, a suction cup, in conjunction with a negative pressure device, separates and classifies unqualified and qualified electricity meters, preventing unqualified meters from being mixed with qualified meters and ensuring the safety of the meters in later use.

[0004] In the aforementioned prior art, when testing smart meters, due to different usage scenarios, varying power and size of smart meters, and different spacing of wire fixing points on the smart meters, setting up multiple testing terminals makes it impossible to adjust the spacing of multiple testing terminals. Generally, one testing terminal is used for testing one by one, resulting in low testing efficiency.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] Example 1: As shown in Figures 1-8, the smart meter withstand voltage testing device of this embodiment includes a workbench 1, a base plate 6 at the lower end of the workbench 1, a smart meter 2 placed on one side of the upper end of the workbench 1, and a testing component slidably disposed on one side of the workbench 1. The testing component includes a rectangular frame 11 slidably disposed on one side of the upper end of the workbench 1, a plurality of testing heads 14 slidably disposed on the side of the rectangular frame 11 near the smart meter 2, and a plurality of triangular blocks 13 slidably disposed on the upper end of the rectangular frame 11, the triangular blocks 13 being respectively located between the testing heads 14. A testing machine 15 is disposed at the end of the testing head 14 away from the smart meter 2, the testing machine 15 is fixed to the upper end of the base plate 6, and the testing machine 15 is connected to the testing head 14 through a wire harness 151.

[0024] Specifically, when testing smart meters 2, due to different usage scenarios, varying power and size, and different spacing of wire fixing points, setting multiple testing heads makes it impossible to adjust the spacing between them. Generally, one testing head is used for testing each meter individually, resulting in low testing efficiency. Using this testing device, the smart meter 2 is placed on the workbench 1, and the position of the testing head 14 is adjusted according to the spacing of the wire fixing points. The triangular block 13 is driven to slide downwards simultaneously within the rectangular frame 11. As the triangular block 13 slides downwards, the testing head 14 slides along the diagonal sides of the triangular block 13. The distance between the testing heads 14 can be adjusted by adjusting the height of the triangular block 13. Multiple testing heads 14 can be set to test the smart meter 2, improving testing efficiency. Furthermore, the spacing of the testing heads 14 can be adjusted according to the size of different smart meters 2, allowing for testing of smart meters 2 of different sizes, thus having a wide range of applications.

[0025] As shown in Figures 3-5, a first U-shaped plate 12 is slidably disposed inside the rectangular frame 11, and several triangular blocks 13 are slidably disposed at the lower end of the first U-shaped plate 12, with each triangular block 13 located between two adjacent detection heads 14.

[0026] As shown in Figures 4 and 5, the pointed corners of the triangular block 13 are facing down, and the hypotenuses on both sides of the triangular block 13 are closely attached to the sides of the detection head 14, with adjacent triangular blocks 13 being placed alternately.

[0027] As shown in Figure 3, a lead screw 121 is rotatably provided on the upper end of the first U-shaped plate 12. The lead screw 121 is threadedly connected to the middle of the upper end of the rectangular frame 11. Scale lines 112 are respectively provided on both sides of the rectangular frame 11.

[0028] As shown in Figure 4, the upper middle part of the triangular blocks 13 located on the same straight line is slidably penetrated by the first cylindrical strip 131. The first cylindrical strip 131 is fixed to the lower end of the first U-shaped plate 12, and the outer sides of the two ends of the first cylindrical strip 131 are respectively fitted with first springs 132.

[0029] As shown in Figure 5, a rectangular hole 111 is provided on one side of the rectangular frame 11. A rectangular slider 141 is fixedly connected to one end of the detection head 14. Several rectangular sliders 141 are slidably disposed inside the rectangular hole 111. A second cylindrical strip 142 is slidably passed through the middle of several rectangular sliders 141. The second cylindrical strip 142 is fixedly connected inside the rectangular hole 111. A second spring 143 is sleeved on the outer side of both ends of the second cylindrical strip 142.

[0030] As shown in Figure 2, a slide table 16 is fixedly connected to the lower end of the rectangular frame 11, and a slide rail 161 is fixedly connected to the upper end of the worktable 1 at the position corresponding to the slide table 16. The slide table 16 is slidably disposed on the upper end of the slide rail 161.

[0031] Specifically, when the spacing of the detection heads 14 needs to be adjusted, the drive screw 121 is rotated, thereby causing the first U-shaped plate 12 to slide up and down inside the rectangular frame 11. The screw 121 drives several triangular blocks 13 to slide up and down. Since adjacent triangular blocks 13 are staggered, each triangular block 13 has a larger sliding space at the lower end of the first U-shaped plate 12. When multiple triangular blocks 13 are driven to slide downwards simultaneously, the triangular blocks 13 squeeze the detection heads 14, causing each detection head 14 to slide along the inclined sides of the triangular blocks 13. The detection heads 14 slide in the rectangular hole 111 through the rectangular slider 141, causing each rectangular slider 141 to slide outside the second spring 143, while squeezing the second spring 143 on both sides, increasing the distance between the detection heads 14. At the same time, each triangular block 13 slides outside the first cylindrical strip 131 and squeezes the first spring 143 on both sides. Spring 132, when rotating screw 121, can accurately control the sliding height of the first U-shaped plate 12 by observing the scale line 112 on the side of the rectangular frame 11. By accurately controlling the sliding height of the first U-shaped plate 12, the sliding height of the triangular block 13 can be accurately controlled, thereby controlling the distance between the detection heads 14. When the first U-shaped plate 12 slides upward, the triangular block 13 slides upward. At the same time, the first spring 132 on both sides releases its elastic force, causing each triangular block 13 to move closer to the center. At the same time, the second spring 143 releases its elastic force, pushing each rectangular slider 141 to move closer to the center. The rectangular slider 141 drives each detection head 14 to move closer to the center. After adjusting the distance between each detection head 14, the slide table 16 is driven to slide on the upper end of the slide rail 161. The slide table 16 drives the rectangular frame 11 to move closer to the smart meter 2, driving the detection head 14 to detect the smart meter 2.

[0032] Example 2: As shown in Figures 6 and 7, compared with Example 1, another embodiment of the present invention is as follows: A clamping assembly is provided on the upper end of the workbench 1. The clamping assembly is used to clamp the smart meter 2. The clamping assembly includes clamping plates 3 that are slidably arranged on both sides of the upper end of the workbench 1. An L-shaped plate 31 is fixedly connected to one side of each clamping plate 3. The lower end of the L-shaped plate 31 is slidably arranged on the upper end of the base plate 6. A bidirectional lead screw 32 is threadedly connected to the middle of the base plate 6. The two ends of the bidirectional lead screw 32 are rotatably arranged on the upper end of the base plate 6 through rectangular blocks 33.

[0033] As shown in Figure 7, a conveyor belt 4 is installed on one side of the upper end of the base plate 6. The conveyor belt 4 is located on one side of the workbench 1 and is used to transport the smart meter 2. A rectangular plate 311 is slidably arranged in the middle of the L-shaped plate 31 on one side. The rectangular plate 311 is located on the upper end of the conveyor belt 4.

[0034] As shown in Figures 6-8, a second U-shaped plate 5 is provided on the side of the conveyor belt 4 away from the workbench 1. The second U-shaped plate 5 is fixed to the upper end of the base plate 6. A rectangular strip 51 is fixed to one side of the upper end of the second U-shaped plate 5. The end of the rectangular strip 51 away from the second U-shaped plate 5 is fixed to the upper end of the base plate 6 through a U-shaped support rod 52. Telescopic plates 53 are slidably provided on both sides of the lower end of the rectangular strip 51.

[0035] Specifically, after placing the smart meter 2 on the upper end of the workbench 1, the bidirectional lead screw 32 is driven to rotate in the middle of the rectangular block 33, causing the L-shaped plate 31 to slide on the upper end of the base plate 6. The L-shaped plate 31 causes the clamping plate 3 to slide on the upper end of the workbench 1. The two clamping plates 3 are adjusted to match the width of the smart meter 2 to be tested. Then, the conveyor belt 4 is started to move several smart meters 2 to be tested closer to one side of the workbench 1. Then, the rectangular plate 311 in the middle of the L-shaped plate 31 on one side of the forward direction of the conveyor belt 4 is driven to slide downward. The smart meter 2 at the upper end of the conveyor belt 4 is conveyed to one side of the rectangular plate 311. At this time, the conveyor belt 4 stops conveying, and then the lower end of the rectangular bar 51 is driven. The telescopic plate 53 on the side away from the workbench 1 slides towards the side closer to the workbench 1, pushing the smart meter 2 on the upper end of the conveyor belt 4 between the two clamping plates 3 on the upper end of the workbench 1. Then, the detection head 14 is driven to detect the smart meter 2. After the detection is completed, the telescopic plate 53 on the lower end of the rectangular bar 51 near the detection head 14 is driven to slide towards the side closer to the conveyor belt 4, which can push the smart meter 2 that has been detected back to the upper end of the conveyor belt 4. Then, the conveyor belt 4 is started again to convey the smart meter 2 that has been detected to one side, and at the same time, the next smart meter 2 to be detected is conveyed to one side of the workbench 1, which can automatically load and unload the smart meter 2.

[0036] Working principle: When testing smart meters 2, the conveyor belt 4 is started, moving several smart meters 2 to be tested closer to one side of the workbench 1. Then, the rectangular plate 311 in the middle of the L-shaped plate 31 on one side of the conveyor belt 4 is driven to slide downwards, and the smart meters 2 at the top of the conveyor belt 4 are conveyed to one side of the rectangular plate 311. At this time, the conveyor belt 4 stops conveying. Then, the bidirectional lead screw 32 is driven to rotate in the middle of the rectangular block 33, causing the L-shaped plate 31 to slide on the top of the base plate 6. The L-shaped plate 31 causes the clamping plate 3 to slide on the top of the workbench 1, adjusting the two clamping plates 3 to be consistent with the width of the smart meters 2 to be tested. Then, the telescopic plate 53 at the lower end of the rectangular bar 51, away from the workbench 1, is driven to slide towards the workbench 1, moving the smart meters 2 at the top of the conveyor belt 4 closer to the workbench 1. The meter 2 is pushed between the two clamping plates 3 at the upper end of the workbench 1. When the spacing of the detection heads 14 needs to be adjusted, the drive screw 121 is rotated, thereby causing the first U-shaped plate 12 to slide up and down inside the rectangular frame 11. The screw 121 drives several triangular blocks 13 to slide up and down. Since adjacent triangular blocks 13 are staggered, each triangular block 13 has a larger sliding space at the lower end of the first U-shaped plate 12. When multiple triangular blocks 13 are driven to slide down at the same time, the triangular blocks 13 squeeze the detection heads 14, causing each detection head 14 to slide along the inclined sides of the triangular blocks 13. The detection heads 14 slide in the rectangular hole 111 through the rectangular slider 141, causing each rectangular slider 141 to slide outside the second spring 143. Simultaneously, the second springs 143 on both sides are compressed, increasing the distance between the detection heads 14. This causes the triangular blocks 13 to slide outside the first cylindrical strip 131, compressing the first springs 132 on both sides. When rotating the lead screw 121, the sliding height of the first U-shaped plate 12 can be accurately controlled by observing the scale lines 112 on the side of the rectangular frame 11. Accurate control of the sliding height of the first U-shaped plate 12 allows for accurate control of the sliding height of the triangular blocks 13, thereby controlling the distance between the detection heads 14. When the first U-shaped plate 12 slides upward, the triangular blocks 13 slide upward, and the first springs 132 on both sides release their elasticity, causing the triangular blocks 13 to move closer to the center. Simultaneously, the second springs 143 release their elasticity, pushing the rectangular blocks 14... The slider 141 moves closer to the center, and the rectangular slider 141 drives each detection head 14 to move closer to the center. After adjusting the distance between each detection head 14, the drive slide 16 slides on the upper end of the slide rail 161. The slide 16 drives the rectangular frame 11 to move closer to the smart meter 2, driving the detection head 14 to detect the smart meter 2. After the detection is completed, the telescopic plate 53 at the lower end of the drive rectangular bar 51, which is close to the detection head 14, slides closer to the conveyor belt 4. This pushes the smart meter 2 that has been detected back to the upper end of the conveyor belt 4. Then, the conveyor belt 4 is started again to transport the smart meter 2 that has been detected to one side, and at the same time, the next smart meter 2 to be detected is transported to one side of the workbench 1. The smart meter 2 can be automatically loaded and unloaded.
