Description

Technical Field

[0001] This application relates to the field of electricity meter testing, and in particular to a rapid electricity meter testing station. Background Technology

[0002] With the deepening of smart grid construction, electricity meters, as key metering instruments, are becoming increasingly complex in function (such as multi-rate, remote communication, load control, etc.), and the number of verification items is also increasing. The state has set higher standards for the accuracy, traceability, and efficiency of metrological verification.

[0003] For a long time, the testing of electricity meters has mainly relied on the traditional manual wiring and reading method. In this method, operators need to use tools such as screwdrivers and wire cutters to manually connect the voltage lines, current lines, and communication cables to the corresponding terminals of the meter under test one by one. This process is not only cumbersome and time-consuming, but also heavily dependent on the operator's skill and sense of responsibility.

[0004] Manual connections are highly susceptible to errors due to loose wiring, incorrect wiring sequence, or excessive contact resistance, and may even lead to short circuit risks, directly affecting the consistency and reliability of test results. With the increasing workload of electricity meter verification, this inefficient, high-error-rate, and labor-intensive method has become a bottleneck restricting verification efficiency and quality, failing to meet the demands of modern, large-scale, and high-quality metrological verification. Summary of the Invention

[0005] To improve testing efficiency, this application provides a rapid testing station for electricity meters.

[0006] The fast testing station for electricity meters provided in this application adopts the following technical solution: A rapid testing platform for electricity meters includes a platform body, a positioning base, a housing, and a test probe. The positioning base is fixedly connected to the upper end of the platform body and is used to position the electricity meter. The housing is slidably connected to the upper end of the platform body. The test probe is fixedly connected to the end of the housing facing the positioning base, and the sliding of the housing is used to control the test probe to connect with the electricity meter interface.

[0007] By adopting the above technical solution, the positioning seat is fixed to the upper part of the platform and used to accurately position the energy meter. At the same time, the housing with built-in test probes is slidably connected to the platform. During operation, simply pushing the housing to slide can drive all test probes to automatically align and reliably connect with the energy meter interface at once. This completely avoids the problems of incorrect connection, missing connection, poor contact and low efficiency that are easily caused by traditional manual wiring. It not only greatly improves the detection efficiency and operational safety, but also ensures the consistency of each connection, thereby improving the accuracy and repeatability of the test results.

[0008] Preferably, it also includes a terminal block and a switch. The platform includes a housing and a base plate. The lower end of the housing is provided with a receiving groove. The base plate is hinged to the outer wall of the housing and is used to cover the opening of the receiving groove. The outer wall of the housing is provided with a mounting opening. The mounting opening communicates with the receiving groove. The terminal block is fixedly connected to the inner wall of the mounting opening. The switch is located in the receiving groove. The terminal block and the test probe are both electrically connected to the switch.

[0009] By adopting the above technical solution, the receiving slot at the lower end of the enclosure and the base plate hinged to the outer wall of the enclosure together form an electrical compartment that can be easily opened and closed. The external standard power cord is connected through the terminal block fixed to the inner wall of the mounting port, and after being uniformly controlled by the switch in the receiving slot, it is then distributed to the test probes on the enclosure. The exposed electrical interfaces are concentrated in the mounting port on the side wall of the enclosure, avoiding the messy distribution of wires on the table. At the same time, the hinged base plate facilitates quick opening and closing for wire inspection or maintenance, while the unified control of the internal switch improves operational safety and ensures the reliability of power management, making the entire testing station neat in appearance, safe in operation, and easy to maintain.

[0010] Preferably, the upper end of the housing is provided with an operating port, which is connected to the receiving groove, and the operating port is used for the switch to extend into.

[0011] By adopting the above technical solution, the operating port is designed specifically for switches, allowing it to extend out or be operated by tools. This enables operators to safely and conveniently control the on / off state of the detection power supply without opening the base plate covering the receiving slot or touching the complex internal wiring. This not only greatly improves the efficiency and convenience of daily operation, but also effectively avoids the risk of loose wiring or accidental contact with live parts that may result from frequent opening and closing of the base plate, further enhancing the safety protection level and human-machine interface of the equipment.

[0012] Preferably, the upper end of the housing is provided with a cable passage, which is connected to the receiving groove.

[0013] By adopting the above technical solutions, the risks of tangling, pulling, and accidental tripping caused by multiple cables running haphazardly on or around the work surface are effectively avoided, keeping the operating area tidy. This not only improves the safety and professional appearance of the equipment, but also provides a clear and unobstructed space for operators to move around and maintain the equipment. At the same time, the centralized cable routing also optimizes the neatness of the internal wiring and heat dissipation conditions, further ensuring the long-term reliability and stability of electrical connections.

[0014] Preferably, it also includes an indicator light. The upper end of the housing is provided with a connection port. The indicator light is fixedly connected to the inner wall of the connection port and electrically connected to the test probe.

[0015] By adopting the above technical solution, when the box slides to correctly connect the test probe to the energy meter and power it on, the indicator light can be directly lit according to the preset detection logic (such as different states such as power on, communication normal, error qualified, etc.). The operator can intuitively and instantly know the current connection status and preliminary test results at the operation position without having to look at other instruments or screens. This not only greatly improves the efficiency and user-friendliness of human-computer interaction, making each step of operation have clear visual confirmation, but also quickly locates faults (such as indicating that the corresponding circuit is abnormal if a certain indicator light is not lit), effectively avoids misjudgment, and optimizes the detection process and problem troubleshooting speed.

[0016] Preferably, the housing includes a fixing plate, a connecting plate, and a mounting plate. The fixing plate and the mounting plate are parallel to each other. The two ends of the connecting plate are fixedly connected to the fixing plate and the mounting plate, respectively. The mounting plate is located between the fixing plate and the positioning seat. The mounting plate has a through-hole, and the test probe is fixedly connected to the inner wall of the through-hole.

[0017] By adopting the above technical solution, all test probes can move precisely and synchronously as a whole, effectively eliminating probe position deviation caused by structural deformation or vibration, ensuring extremely high repeatability and contact reliability of each connection with the electricity meter interface, thus providing a solid mechanical foundation for stable and consistent electrical testing.

[0018] Preferably, it also includes a quick clamp, which is located on the side of the fixed plate away from the mounting plate. The base of the quick clamp is fixedly connected to the upper end of the platform, and the pressure head of the quick clamp is fixedly connected to the fixed plate.

[0019] By adopting the above technical solution, when the operator drives the handle of the quick clamp, its pressure head directly drives the entire housing (including the fixing plate, mounting plate and test probe) to slide steadily and effortlessly towards the electricity meter along the precision track. At the end of the stroke, the quick clamp's unique linkage or cam force amplification and self-locking mechanism instantly transforms into a huge, continuously maintained vertical locking force. This not only ensures a tight and reliable contact between the test probe and the electricity meter interface, eliminating test errors caused by poor contact, but also combines the originally separate "alignment connection" and "force application and clamping" operations into one, greatly simplifying the operation process and significantly improving the consistency of clamping force each time. Thus, while ensuring the absolute reliability of the electrical performance of the connection, it achieves truly fast, efficient and highly repeatable testing.

[0020] Preferably, it also includes a guide member, which has a support plate and a guide rod. The support plate is fixedly connected to the upper end of the platform, and the guide rod is fixedly connected to the support plate. The length direction of the guide rod is parallel to the sliding direction of the box. The fixed plate has a guide opening, and the guide rod is slidably connected to the inner wall of the guide opening.

[0021] By adopting the above technical solution, the motion trajectory is strictly limited to a single axis, completely eliminating the possibility of lateral swing, twisting or jamming. This ensures that all test probes can achieve perfect alignment and connection with the power meter interface with extremely high repeatability every time, greatly improving the consistency and reliability of the test. At the same time, the support of the guide rod also shares the lateral force of the quick clamp, improving the stability and service life of the entire motion system.

[0022] Preferably, the test needle includes a metal sleeve, a spring, and a probe. The metal sleeve is fixedly connected to the inner wall of the orifice. The end of the metal sleeve facing the positioning seat is provided with a sliding groove. One end of the spring is fixedly connected to the bottom of the sliding groove, and the other end of the spring is fixedly connected to the probe. The probe is slidably connected to the wall of the sliding groove.

[0023] By adopting the above technical solution, an adaptive, highly reliable, and low-damage electrical contact with the electricity meter interface is achieved: the metal sleeve, as a fixed base and electrical channel, is precisely installed in the through-hole of the fixed plate; the probe can extend and float within the sliding groove of the metal sleeve under the continuous pressure of the internal spring; when the housing slides and the probe contacts the electricity meter interface, the probe will adaptively retract according to the slight height difference or unevenness of the interface plane, while the constant pressure provided by the spring ensures the stability and balance of the contact force, avoiding probe bending, interface scratches, or excessive contact resistance caused by insufficient pressure due to rigid contact. This ensures the consistency, low impedance, and long life of the electrical connection under various working conditions, greatly improving the stability of the detection signal and the durability of the overall equipment.

[0024] Preferably, it also includes a buffer pad, and the upper end of the positioning seat is provided with a positioning groove, the positioning groove extends in the direction close to the box body, and the buffer pad is fixedly connected to the groove wall of the positioning groove.

[0025] By adopting the above technical solution, when the electricity meter slides into the positioning groove, the buffer pad can effectively absorb the impact and vibration at the moment of contact with the groove wall, preventing the meter casing from being scratched by rigid collision. At the same time, the moderate frictional resistance it provides helps the meter to stay stably in the preset position, providing a stable and non-offset reference for the subsequent sliding of the box and the precise docking of the test probe. Thus, while improving the operating feel and equipment durability, it ensures a high degree of consistency in the starting position of each test.

[0026] In summary, this application includes at least one of the following beneficial technical effects: By fixing the positioning base to the upper part of the platform and using it to accurately position the energy meter, and making the housing with built-in test probes slide to the platform, during operation, simply push the housing to slide and drive all test probes to automatically align and reliably connect with the energy meter interface at once. This completely avoids the problems of incorrect connection, missing connection, poor contact and low efficiency that are easily caused by traditional manual wiring. It not only greatly improves the detection efficiency and operational safety, but also ensures the consistency of each connection, thereby improving the accuracy and repeatability of the test results. Once the housing slides to correctly connect the test probe to the energy meter and power it on, the indicator light will illuminate directly according to the preset detection logic (such as different states like power on, communication normal, and error compliance). Operators can intuitively and instantly obtain the current connection status and preliminary test results from the operating position without having to check other instruments or screens. This not only greatly improves the efficiency and user-friendliness of human-machine interaction, making each step of the operation clearly visually confirmed, but also quickly locates faults (such as indicating that the corresponding circuit is abnormal if an indicator light is not lit), effectively avoiding misjudgment and optimizing the detection process and troubleshooting speed. It achieves adaptive, highly reliable, and low-damage electrical contact with the electricity meter interface: the metal sleeve, serving as a fixed base and electrical channel, is precisely installed within the through-hole of the fixing plate; the probe, under the continuous pressure of the internal spring, can extend and float within the sliding groove of the metal sleeve; when the housing slides and the probe contacts the electricity meter interface, the probe will adaptively retract according to the slight height difference or unevenness of the interface plane, while the constant pressure provided by the spring ensures the stability and balance of the contact force, avoiding probe bending, interface scratches, or excessive contact resistance caused by insufficient pressure due to rigid contact. This ensures the consistency, low impedance, and long life of the electrical connection under various operating conditions, greatly improving the stability of the detection signal and the overall durability of the equipment.

[0033] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0034] This application discloses a rapid testing platform for electricity meters. (Refer to...) Figure 1 and Figure 2 The fast testing platform for electricity meters includes a platform body 1, terminal block 2, communication interface 3, switch 4, positioning base 5, housing 6, test probe 7, buffer pad 8, guide component 9, quick clamp 10, and indicator light 20.

[0035] The platform 1 includes a box 11, a base plate 12, and a hinge 13. The lower end of the box 11 is provided with a receiving groove 111. One end of the base plate 12 is hinged to the outer wall of the box 11 via the hinge 13. The base plate 12 is used to cover the opening of the receiving groove 111. The other end of the base plate 12 is detachably fixed to the outer wall of the box 11 via a mechanical lock. The mechanical lock can be a snap-on type, with the buckle body connected to the outer wall of the box 11 and the buckle seat connected to the base plate 12.

[0036] Reference Figure 1 and Figure 2Along the length of the housing 11, one end of the housing 11 is provided with an installation port 112 and a placement port 113.

In this embodiment, there are ten installation ports 112, which are arranged in a two-row, five-column array. The communication interface 3 is fixedly connected to the inner wall of the placement port 113.

[0037] Switch 4 is located inside receiving groove 111 and is fixedly connected to the end of base plate 12 facing the bottom of receiving groove 111. The upper end of housing 11 is provided with operating port 114, which is connected to receiving groove 111 and is used for switch 4 to extend into. Terminal 2 and communication interface 3 are both electrically connected to switch 4.

[0038] Reference Figure 2 The positioning seat 5 is fixedly connected to the upper end of the housing 11. The housing 6 is located between the positioning seat 5 and the terminal 2. The housing 6 is slidably connected to the upper end of the housing 11. The test probe 7 is fixedly connected to the end of the housing 6 facing the positioning seat 5. The upper end of the positioning seat 5 is provided with a positioning groove 51. The positioning groove 51 is used to place the energy meter. The positioning groove 51 extends towards the housing 6 to avoid the insertion of the test probe 7, so that the housing 6 slides to control the test probe 7 to connect with the energy meter interface. The buffer pad 8 is fixedly connected to the groove wall and the bottom of the positioning groove 51 to protect the energy meter.

[0039] Reference Figure 2 and Figure 3 The housing 6 includes a fixing plate 61, a connecting plate 62, a mounting plate 63, and connecting posts 64. The fixing plate 61 and the mounting plate 63 are parallel to each other and are perpendicular to the upper surface of the housing 11. The two ends of the connecting plate 62 are fixedly connected to the upper ends of the fixing plate 61 and the mounting plate 63, respectively. The mounting plate 63 is located between the fixing plate 61 and the positioning seat 5. The connecting posts 64 are located below the connecting plate 62, and the two ends of the connecting posts 64 are fixedly connected to the fixing plate 61 and the mounting plate 63, respectively. There are four connecting posts 64, which are located near the four corners of the mounting plate 63. The lower end of the connecting plate 62 is provided with a guide surface 621, which is located on the side of the mounting plate 63 away from the fixing plate 61. The height of the guide surface 621 increases as it moves away from the mounting plate 63. The guide surface 621 is used to abut against the upper surface of the electricity meter.

[0040] Mounting plate 63 has a through-hole 631. The test probe 7 includes a metal sleeve 71, a spring 72, and a probe 73. The metal sleeve 71 is fixedly connected to the inner wall of the through-hole 631. The end of the metal sleeve 71 facing the positioning seat 5 has a sliding groove 711. One end of the spring 72 is fixedly connected to the bottom of the sliding groove 711, and the other end of the spring 72 is fixedly connected to the probe 73. The probe 73 is slidably connected to the wall of the sliding groove 711. The upper end of the housing 11 has a wire passage 115, which connects to the receiving groove 111. The metal sleeve 71 is electrically connected to the switch 4 through a wire. The wire passes between the mounting plate 63 and the fixing plate 61, passes through the wire passage 115, and connects to the switch 4. There are multiple through-holes 631, which are divided into two groups. The two groups of through-holes 631 are located near the upper and lower ends of the mounting plate 63, respectively. Each through-hole 631 corresponds to an interface of the electricity meter.

[0041] Reference Figure 1 The guide member 9 is provided with a support plate 91 and a guide rod 92. There are two guide members 9, which are located on both sides of the box body 6. One of the guide members 9 is located between the box body 6 and the operating port 114. The support plate 91 is fixedly connected to the upper end of the platform 1, and the guide rod 92 is fixedly connected to the support plate 91. The length direction of the guide rod 92 is parallel to the sliding direction of the box body 6. The fixed plate 61 is provided with a guide opening 611, and the guide rod 92 is slidably connected to the inner wall of the guide opening 611.

[0042] The quick clamp 10 is located on the side of the fixed plate 61 away from the mounting plate 63. The base of the quick clamp 10 is fixedly connected to the upper end of the platform 1, and the pressure head of the quick clamp 10 is fixedly connected to the fixed plate 61.

[0043] Reference Figure 1 and Figure 2 The upper end of the housing 11 is provided with a connection port 116. The connection port 116 is located on the side of the positioning seat 5 away from the housing 6. The indicator light 20 is fixedly connected to the inner wall of the connection port 116. The indicator light 20 is electrically connected to the test needle 7. There are multiple connection ports 116, and the multiple connection ports 116 are distributed in an array, corresponding one-to-one with the test needle 7.

[0044] Reference Figure 1 and Figure 4It also includes a heat sink 30, which includes a fan 301, a filter 302, a distance sensor 303, and a controller 304. The mounting plate 63 has a ventilation opening 632 located between two sets of through-holes 631. The fan 301 is fixedly connected to the inner wall of the ventilation opening 632. The rotation of the fan 301 causes external air to flow between the mounting plate 63 and the energy meter, carrying away the heat from the test probe 7 and extending its service life. The mounting plate 61 has an exhaust vent 612 directly opposite the ventilation opening 632. The air blown out by the fan 301 affects the mounting plate 63 and... The wires between the fixed plates 61 dissipate heat. The exhaust port 612 is located above the wire passage 115 to increase the airflow velocity above the wire passage 115. The outer wall of the box 6 has multiple air inlets 117, which are divided into two groups. The two groups of air inlets 117 are located at both ends of the width direction of the box 11. The air inlets 117 are connected to the receiving groove 111. The filter screen 302 is fixedly connected to the groove wall of the receiving groove 111. The filter screen 302 is used to cover the air inlets 117. External air enters the receiving groove 111 and is then discharged through the wire passage 115, cooling the electronic components in the receiving groove 111. The distance sensor 303 is fixedly connected to the end of the support plate 91 near the quick clamp 10 facing the fixed plate 61. The distance sensor 303 is used to detect the distance of the fixed plate 61, thereby determining the position of the probe 73. The distance sensor 303 and the fan 301 are electrically connected to the controller 304.

[0045] Reference Figure 3 and Figure 4It also includes a prompting element 40, which includes a piezoelectric ceramic sheet 401, a piezoelectric sensor 402, and a prompt light 403. The piezoelectric ceramic sheet 401 is located between the bottom of the positioning groove 51 and the buffer pad 8. The piezoelectric ceramic sheet 401 is fixedly connected to the bottom of the positioning groove 51 and electrically connected to the controller 304. When the distance sensor 303 detects that the probe 73 has moved to a distance of 2-3 mm from the energy meter interface, the controller 304 issues a command to apply a brief high-frequency alternating voltage to the piezoelectric ceramic sheet 401, causing it to vibrate slightly. This vibration causes the energy meter to make a slight adjustment in the positioning groove 51 under its own weight and slight inertia. With the help of the guide surface 621, the energy meter is subjected to force to ensure that the interface is aligned with the probe 73, eliminating the slight angular deviation or jamming caused by manual placement. The piezoelectric sensor 402 is located between the groove wall of the positioning groove 51 and the buffer pad 8. The piezoelectric sensor 402 is fixedly connected to the groove wall of the positioning groove 51 facing the mounting plate 63. The indicator light 403 is fixedly connected to the housing 11. Both the piezoelectric sensor 402 and the indicator light 403 are electrically connected to the controller 304. The housing 6 is close to the energy meter, so that the probe 73 is connected to the energy meter interface. The spring 72 connected to the probe 73 is compressed, and the pressure is transmitted to the piezoelectric sensor 402 through the energy meter housing. The controller 304 detects the weak charge signal generated by the piezoelectric sensor 402. When the signal strength reaches the preset threshold, it means that all probes 73 have made reliable contact, and the indicator light 403 lights up green to indicate "good contact" to the operator. When the signal is abnormal, the low pressure indicator light 403 lights up yellow to indicate poor contact, and the high pressure indicator light 403 lights up red to indicate misalignment. This solves the risk of misalignment and detection errors caused by blind pressure.

[0046] Reference Figure 4 and Figure 5It also includes a cleaning component 50, which includes a slide 501, a drive component 502, and a cleaning box 503. There are two cleaning components 50, which are respectively located on the upper and lower sides of the test needle 7. The slide 501 is slidably connected to the end of the mounting plate 63 facing the positioning seat 5. The sliding direction of the slide 501 is vertical. The drive component 502 drives the slide 501 to move up and down. The drive component 502 is electrically connected to the controller 304 and is a miniature cylinder. The outer wall of the cleaning box 503 is fixedly connected to the slide 501. The end of the cleaning box 503 facing the test needle 7 is provided with a cleaning groove 5031. The distance from the groove wall of the cleaning groove 5031 to the mounting plate 63 increases as it approaches the test needle 7. When the housing 6 moves away from the positioning seat 5, the slide 501 moves towards the test probe 7. The wall of the cleaning tank 5031 slides over the probe 73 to clean the end of the probe 73. Impurities fall into the lower cleaning tank 5031. When not in use, the probe 73 is covered. When the housing 6 moves towards the positioning seat 5, the slide 501 moves away from the test probe 7. The wall of the cleaning tank 5031 slides over the probe 73 to clean the end of the probe 73. Impurities fall into the lower cleaning tank 5031. The fan 301 rotates to carry away the impurities.

[0047] The implementation principle of a rapid testing station for electricity meters in this application embodiment is as follows: the electricity meter is placed in the positioning slot 51, the handle of the quick clamp 10 is manually operated to push the box 6 close to the electricity meter, after the probe 73 is correctly connected to the electricity meter, the switch 4 is turned on, after power is supplied, the indicator light 20 performs the test according to the preset test logic and obtains the test result.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
