Description

Technical Field

[0001] The present invention relates to the technical field of electric meter measurement, and particularly to a detecting pin device for electric energy meters. Background Art

[0002] An electric energy meter is an instrument used to measure electric energy, also known as a watt-hour meter or kilowatt-hour meter; it has a rich variety, including single-phase, three-phase three-wire, three-phase four-wire, etc. according to phase; and induction type, static type, electromechanical integrated type, etc. according to working principle; the main parameters of the electric energy meter include voltage, power supply frequency, rated current and rated maximum current, accuracy level, etc. The patent with the application number CN201110369881.0 discloses a detecting pin device for electric energy meters, which includes a detection table, a support frame fixed on the detection table, a longitudinal transfer mechanism arranged on the support frame, a wiring terminal connected to the longitudinal transfer mechanism, a drive control module connected to the longitudinal transfer mechanism for controlling the action of the longitudinal transfer mechanism, and a test module connected to the wiring terminal; the wiring terminal includes a terminal seat connected to the longitudinal transfer mechanism, and a plurality of probes passing through the terminal seat, and the probes include a current pin for transmitting electricity to the electric energy meter and a signal pin connected to the test module for transmitting the detection information of the electric energy meter. Currently, the main method for detecting electric energy meters is to insert the connection pins at the detection end into the electric energy meter, and then input current through the pins to detect it. During the continuous insertion and extraction process of the pins, wear will occur, and the pins will heat up under the action of current, which will exacerbate the wear. After a long time of detection, the volume of the pins will shrink and they will not be able to contact the metal sheet inside the electric energy meter, resulting in the inability to detect, and even high-temperature electric arcs may be generated, posing a safety hazard and affecting the detection. Summary of the Invention

[0003] Aiming at the deficiencies of the prior art, the present invention provides a detecting pin device for electric energy meters to solve the problems raised in the above background art.

[0004] To achieve the above object, the present invention is realized through the following technical solutions: A detecting pin device for electric energy meters includes an electric energy meter, a detection plug-in end is arranged on the right side of the electric energy meter, several pins are fixedly connected to the left side of the detection plug-in end, a pin substitution mechanism is fixedly connected to the left side of the detection plug-in end and on the right side of the electric energy meter, and a positioning component is fixedly connected to the bottom of the electric energy meter.

[0007] Preferably, a first insulating air duct is fixedly connected to the outer wall of the copper guide box, and the copper guide box is fixedly connected to another first insulating air duct through the first insulating air duct. The copper guide boxes can communicate with each other through the first insulating air duct. A second insulating air duct is fixedly connected to the outer wall of one of the copper guide boxes, and an air pump is fixedly connected to the other end of the second insulating air duct connected to the copper guide box.

[0008] Preferably, the positioning assembly includes a fixed box arranged at the bottom of the electric energy meter. Outer side fixing plates are fixedly connected to the front and back of the top of the fixed box close to the electric energy meter. Springs are fixedly connected to one sides of the two outer side fixing plates close to the electric energy meter. Arc-shaped plates are fixedly connected to one sides of the two springs close to the electric energy meter. Positioning protrusions are fixedly connected to the inner sides of the arc-shaped plates.

[0009] Preferably, a guide post is fixedly connected to the side of the outer side fixing plate close to the electric energy meter, and the side of the guide post close to the electric energy meter is fixedly connected to the corresponding arc-shaped plate.

[0010] Preferably, a fixed bottom plate is fixedly connected to the bottom of the fixed box. A movable pushing-in box is movably connected to the right side of the fixed box. The top of the movable pushing-in box is fixedly connected to the fixed platform. A pushing handle is fixedly connected to the right side of the movable pushing-in box.

[0011] Preferably, a notch is arranged at the top of the fixed box, and a notch is arranged at the corresponding position of the top of the movable pushing-in box and the top of the fixed box. When the movable pushing-in box moves to the left, the gas in the fixed box and the movable pushing-in box will be discharged from the notch under the air pressure, playing a damping role.

[0012] The present invention provides an electric energy meter detection pin device. It has the following beneficial effects: 1. The electric energy meter detection pin device performs detection by inserting a copper conduit into the electric energy meter, allowing the detection plug-in end to transfer current to the copper conductive ring through the pin, and the copper conduit transfers the current to the copper conductive top plate through conduction, and the copper conductive box is filled with gas to make the two copper conductive top plates expand outward, thereby making the copper conductive top plates contact with the metal conductor inside the electric energy meter, thereby realizing the transmission of current, avoiding the wear of the pins caused by multiple detections, and better performing detection.

[0013] 2. The electric energy meter detection pin device discharges gas through the airway in the copper conduit to open the copper guide top plate. At the same time, the gas is discharged outward through the holes set on the electric energy meter, thereby realizing the heat dissipation of the heat generated by the internal resistance of the conductor through which the current passes through the airflow, reducing the detection temperature, making the detection process safer and conducive to continuous detection.

[0014] 3. The electric energy meter detection pin device pushes the electric energy meter to the right from the left side of the fixed box and in the middle of each arc plate of the chain. In the process of pushing to the positioning protrusion, the electric energy meter will gradually push the arc plate outward and compress the spring at the same time. The electric energy meter will be located in the middle position under the mutual push of the two springs, and then the pushing handle will push the movable pushing box to the left, and then the fixed platform will be moved to allow the copper conduit to be accurately inserted into the electric energy meter, thereby realizing automatic alignment of the electric energy meter and facilitating detection.

[0015] 4. The electric energy meter detection pin device, when pushing the movable push box, since the movable push box and the fixed box form a structure with a cavity with a notch inside, when the push handle is pushed quickly, the gas will quickly flow through the notch. Since the notch is limited, the pushing resistance will be large. When pushing slowly, the resistance received is small, which can prevent the limbs of the inspector from being located between the copper conduit and the electric energy meter, and causing harm to the human body due to excessive pushing.

[0016] 5. The electric energy meter detection pin device pushes the push handle outward to pull the copper conduit out of the electric energy meter. During this process, the fixed box and the movable push box will inhale gas from the notch, and an inhaled airflow will be generated at the copper conduit. The flowing airflow can cool the outer wall of the copper conduit, thereby making the detection safer and conducive to continuous detection. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0021] Embodiment 1: Please refer to Figure 1-8 , the present invention provides a technical solution: a detection pin device for an electric energy meter, including an electric energy meter 1, a detection plug-in end 2 is arranged on the right side of the electric energy meter 1, several pins 3 are fixedly connected to the left side of the detection plug-in end 2, a substitution insertion mechanism 4 is fixedly connected to the left side of the detection plug-in end 2 and on the right side of the electric energy meter 1, and a positioning component 5 is fixedly connected to the bottom of the electric energy meter 1; The substitution insertion mechanism 4 includes: Copper conducting ring 403, and the copper conducting ring 403 is fixedly connected to the outer wall of the pin 3; Copper conducting box 402, and the copper conducting box 402 is fixedly connected to the left side of the corresponding copper conducting ring 403; Copper conducting pipe 404, and the copper conducting pipe 404 is fixedly connected to the left side of the corresponding copper conducting box 402.

[0022] By fixedly connecting the outer wall of the pin 3 with the copper conducting ring 403, the length of the pin 3 is extended.

[0023] An insulating fixing shell 401 is fixedly connected to the outer wall of the copper conducting box 402. The copper conducting boxes 402 are all fixedly connected inside the insulating fixing shell 401. A fixing platform 412 is fixedly connected to the bottom of the insulating fixing shell 401, and the bottom of the detection plug-in end 2 is fixedly connected to the fixing platform 412.

[0024] Two copper conducting top plates 405 are movably connected to the left side of the copper conducting pipe 404. Elastic pieces 406 are fixedly connected to the outer side of the corresponding copper conducting top plates 405 on the outer wall of the copper conducting pipe 404. A closing small plate 408 is fixedly connected to the inner side of the copper conducting top plates 405. Side plates 407 are fixedly connected to the front and back of the corresponding copper conducting top plates 405 on the left side of the copper conducting pipe 404. An air passage communicating with the inside of the copper conducting box 402 is arranged inside the copper conducting pipe 404.

[0025] The copper conducting pipe 404 is inserted into the electricity meter 1 for detection. The detection plug-in end 2 transfers the current to the copper conducting ring 403 through the pin 3. The copper conducting ring 403 then transfers the current to the copper conducting pipe 404 through the copper conducting box 402. The copper conducting pipe 404 transfers the current to the copper conducting top plates 405. When gas is filled inside the copper conducting box 402, the gas will reach the left side through the air passage inside the copper conducting pipe 404. Since the space between the side plate 407 and the copper conducting top plate 405 is sealed by the closing small plate 408, the gas between the copper conducting top plates 405 gradually increases, causing the two copper conducting top plates 405 to expand outward and the elastic pieces 406 to bend, thereby making the copper conducting top plates 405 contact the metal conductors inside the electricity meter 1, and then realizing the transfer of current. By observing the value displayed on the electricity meter 1 and the value input by the detection plug-in end 2, the electricity meter 1 is detected. After the detection is completed, the gas filling inside the detection plug-in end 2 stops. The elastic pieces 406 will recover their deformation and push the copper conducting top plates 405 back to the initial state. The copper conducting pipe 404 is pulled out from the inside of the electricity meter 1. During the plugging and unplugging process, the copper conducting top plates 405 are prevented from contacting the metal conductors inside the electricity meter 1.

[0026] A first insulating air duct 409 is fixedly connected to the outer wall of the copper guide box 402, and the copper guide box 402 is fixedly connected to another first insulating air duct 409 through the first insulating air duct 409. The copper guide boxes 402 can be interconnected through the first insulating air duct 409, and a second insulating air duct 411 is fixedly connected to the outer wall of one of the copper guide boxes 402, and the other end of the second insulating air duct 411 connected to the copper guide box 402 is fixedly connected to an air pump machine 410.

[0027] When the copper conduit 404 is inserted into the electric energy meter 1, the air pump 410 pumps gas into one of the copper guide boxes 402 through the second insulating air guide tube 411, and the copper guide box 402 transfers the gas out through the first insulating air guide tube 409, thereby pumping gas into all the copper guide boxes 402, and allowing the gas to expand all the copper guide top plates 405, thereby realizing current conduction between the pin 3 and the metal sheet inside the electric energy meter 1.

[0028] When the gas is discharged through the airway in the copper conduit 404 to expand the copper guide top plate 405, the gas will also be discharged outward through the holes set on the electric energy meter 1, thereby achieving the heat dissipation of the heat generated by the internal resistance of the conductor through which the current passes through the airflow, thereby reducing the detection temperature and making the detection process safer.

[0029] Example 2: Please refer to Figure 1-11 Based on the first embodiment, the present invention provides a technical solution: The positioning assembly 5 includes a fixing box 501, which is arranged at the bottom of the electric energy meter 1. The top of the fixing box 501 is located at the front and back of the electric energy meter 1 and is fixedly connected with an outer fixing plate 504. The two outer fixing plates 504 are fixedly connected with springs 506 on one side close to the electric energy meter 1. The two springs 506 are fixedly connected with an arc plate 507 on one side close to the electric energy meter 1. The inner side of the arc plate 507 is fixedly connected with a positioning protrusion 508.

[0030] A guide post 505 is fixedly connected to a side of the outer fixing plate 504 close to the electric energy meter 1 , and a side of the guide post 505 close to the electric energy meter 1 is fixedly connected to a corresponding arc-shaped plate 507 .

[0031] Push the energy meter 1 to the right from the left side of the fixed box 501 and in the middle of each arc plate 507 of the chain. During the pushing process, the energy meter 1 will gradually push the arc plate 507 outward when passing through the arc edge of the arc plate 507, and at the same time compress the spring 506. The guide column 505 will limit the moving direction of the arc plate 507 until it is pushed to the positioning protrusion 508. At this time, the energy meter 1 is no longer pushed and is located in the middle position under the mutual push of the two springs 506.

[0032] The bottom of the fixed box 501 is fixedly connected to a fixed bottom plate 509. The right side of the fixed box 501 is movably connected to a movable push-in box 502. The top of the movable push-in box 502 is fixedly connected to a fixed table 412, and the right side of the movable push-in box 502 is fixedly connected to a push handle 503.

[0033] Push the push handle 503 to the left. This will cause the push handle 503 to push the movable push-in box 502 to move leftward, and then move the fixed table 412 to accurately insert the copper conduit 404 into the electricity meter 1, so that the detection plug-in end 2 can energize the electricity meter 1 through the pins 3 to achieve detection. There is a notch on the top of the fixed box 501, and a notch is provided at the corresponding position on the top of the movable push-in box 502 and the top of the fixed box 501. When the movable push-in box 502 moves leftward, the gas in the fixed box 501 and the movable push-in box 502 will be discharged from the notch under air pressure, playing a damping role.

[0034] When pushing the movable push-in box 502, since the movable push-in box 502 and the fixed box 501 form a structure with a cavity having a notch inside, when quickly pushing the push handle 503, the gas will flow quickly through the notch. Due to the limited notch, the resistance to pushing will be relatively large. When pushing slowly, the received resistance is small, which can prevent the limbs of the tester from being located between the copper conduit 404 and the electricity meter 1 and being damaged by excessive pushing.

[0035] After the detection is completed, push the push handle 503 outward to withdraw the copper conduit 404 from the electricity meter 1. During this process, the fixed box 501 and the movable push-in box 502 will inhale gas from the notch, generating an inhaled air flow at the copper conduit 404. The flowing air flow can play a role in cooling the outer wall of the copper conduit 404.

[0036] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
