Description

Technical Field

[0001] The invention relates to the technical field of electric energy meter calibration, and in particular to an error detection device used for electric energy meter measurement. Background Art

[0002] In the prior art, an electric energy meter calibrator is an instrument used to calibrate the accuracy and error of an electric energy meter. It can measure the voltage, current, power and other electrical parameters of the power grid, determine wiring errors, and realize on-site calibration, data storage and computerized management. It is widely used in the power industry and other industries.

[0003] During the calibration of the electric energy meter, since the electric energy meter usually has multiple detection points, multiple wires need to be connected to the calibration instrument. However, in the process of the existing electric energy meter calibration instrument, the traditional calibration method often requires the staff to manually connect each wire and the corresponding connector to the interface of the calibration instrument one by one. This process is time-consuming and prone to fatigue and negligence, thus affecting the accuracy and efficiency of the calibration. In addition, since the staff needs to operate the wires and connectors one by one, it is easy for the connector to fail to be correctly connected to the interface due to improper operation or negligence, or to become loose and detached after being connected, thereby affecting the accuracy of the electric energy meter measurement error detection and calibration data. In the traditional calibration method, the plugging process of the connector and the interface also lacks stability guarantee, and it is easy to become loose and detached due to external force, which not only affects the accuracy of the calibration, but also causes damage to the calibration equipment. In addition, the interface of the existing electricity meter calibrator is usually not equipped with a corresponding protective blocking structure, which makes the interface exposed to the external environment for a long time. When the interface is exposed to the external environment for a long time, it is easy to accumulate impurities such as dust and sand. These impurities not only affect the appearance of the interface, but also enter the interior of the interface, resulting in poor connection or damage to the connector when it is subsequently inserted, thereby affecting the accuracy of the calibration.

[0016] Compared with the prior art, the present invention has the following beneficial effects: (1) By setting up a centralized access mechanism and utilizing the elastic resetting effect of the elastic telescopic column on the push plate, the movable sleeve can be pushed centrally so that the connector is inserted into the interface, thereby realizing the rapid and automatic plugging of the connector and the interface, enabling centralized access and unified management of the connector, reducing human intervention, and eliminating the need for staff to operate wires and connectors one by one, thereby reducing errors caused by improper operation or negligence and improving the accuracy of the measurement error detection and verification data of the electric energy meter; Among them, the elastic resetting effect of the elastic telescopic column on the push plate can make the push plate tightly insert the connector into the interface, effectively preventing the connector from loosening and detaching due to external force during the mutual plugging process with the interface, thereby increasing the plugging stability of the connector and the interface, avoiding the error in the data results of the metering error detection and verification of the electric energy meter, thereby improving the accuracy of the detection data and reducing the probability of repeated verification; Among them, by utilizing the clip-on design of the mounting frame and its top cover plate, the top cover plate can cover the mounting frame when not in use to form a relatively closed space between them, so as to store and protect each structure, prevent dust, impurities and pollutants in the outside air from adhering to the surface of the structure as the air circulates, and also reduce contact with objects in the external environment when not in use, thereby increasing the overall service life of the structure.

[0017] (2) Through the setting of the opening and closing regulating mechanism, when the push plate pushes the movable sleeve to drive the joint to move toward the interface for plugging, the linkage design of the first connecting plate can drive the sealing plate to slide upward on the side wall of the calibrator body to open the blockage of the interface, so that the interface is exposed so that the joint and the interface can be plugged in, thereby realizing the function of synchronously driving and opening the sealing plate while the joint and the interface are plugged in.

This design can not only prevent the connector from loosening during the use of the connector and the interface, but also ensure the signal transmission quality between the calibrator body and the electric energy meter and the accuracy of the calibration data.

The sealing plate 604 is used to seal the interface 2 .

[0025] Please refer to Figures 3 to 6 , better: when the connector 4 and the interface 2 are not initially plugged in, the sealing plate 604 blocks the interface 2, which can prevent external dust from entering the interior of the interface 2 and affecting the subsequent insertion and use of the connector 4.

[0026] The effects achieved by this embodiment are as follows: compared with the prior art, by setting the opening and closing regulating mechanism 6, in the process of the push plate 507 pushing the movable sleeve 504 to drive the connector 4 to move toward the interface 2 for plugging, the linkage design of the first connecting plate 602 can drive the sealing plate 604 to slide upward on the side wall of the calibrator body 1 to open the blockage of the interface 2, so that the interface 2 is exposed, so that the connector 4 and the interface 2 can be plugged in, thereby realizing the function of synchronously driving and opening the sealing plate 604 while the connector 4 and the interface 2 are plugged in. This design eliminates the need for the staff to operate the opening and closing of the sealing plate 604 separately, and increases the compactness and linkage between the structures, so that the plugging and unblocking steps can be completed in one go, thereby simplifying the operation process and improving the operation efficiency; Among them, the end where the connector 4 is located is positioned at the interface 2, and the design of automatic operation is combined to reduce the difficulty of the calibration process, so that non-professionals can easily complete the calibration work, so that there is no need to pre-match the connector 4 and the interface 2 when using, thereby saving the preparation time for calibration and improving the efficiency of calibration; In addition, since the sealing plate 604 initially covers the interface 2, the interface 2 can be sealed when not in use to prevent external dust from entering the interior of the interface 2 and affecting the subsequent insertion and use of the connector 4, thereby ensuring the cleanliness of the interface 2 and avoiding poor connection or damage to the connector 4 due to contamination by impurities, thereby ensuring the connection quality between the calibrator body 1 and the electric energy meter.

The L-shaped follower plate 703 is slidably connected between the calibrator body 1 and the bending plate 503 . The arc-shaped locking plate 704 is slidably connected to the bending plate 503 .

[0029] The effects achieved by this embodiment are as follows: compared with the prior art, through the setting of the locking control mechanism 7, while the interface 2 is opened, the linkage effect of the second connecting plate 702 can be utilized, and the two arc-shaped locking plates 704 can be driven to move toward each other in cooperation with the L-shaped driven plate 703, so as to synchronously lock the connector 4. This design can not only prevent the connector 4 from loosening during the process of being plugged in and used with the interface 2, but also ensure the signal transmission quality between the calibrator body 1 and the electric energy meter, and ensure the accuracy of the calibration data. At the same time, by locking the connector 4 through the arc-shaped locking plate 704, the risk of misoperation caused by improper manual operation is reduced, and the stable connection between the calibrator body 1 and the electric energy meter is effectively ensured, thereby reducing the risk of equipment damage caused by poor connection, helping to improve the durability of the equipment, and reducing the maintenance cost caused by frequent replacement of damaged parts.

[0030] The complete usage steps and working principle of the above embodiment are as follows: In the initial state: Figure 1 and Figure 2 As shown, the calibration instrument body 1 and the mounting frame 501 are fixedly connected, and a top cover plate 502 is provided on the top of the mounting frame 501.

At the same time, the protection formed by the combination of the top cover plate 502 and the mounting frame 501 can also effectively prevent the structures in the space from contacting and colliding with objects in the external environment when the equipment is not in use, thereby improving the overall service life of the structure, and through centralized management, the various structures can be arranged and stored in an orderly manner, so that the structure of the entire calibration equipment is more compact, saving space, and being easy to carry and transport.

[0031] In addition, it should be noted that Figure 3 and Figure 4 As shown, the wire 3 is wound on the outer surface of the winding roller 515, one end of the wire 3 is connected to a connector 4 adapted to the interface 2, and the other end of the wire 3 is connected to a plug adapted to the electric energy meter. Initially, the plug is hung in the mounting frame 501 through the winding of the wire 3, and the connector 4 is fixedly arranged on the inner surface of the movable sleeve 504, which can facilitate the subsequent control and driving of the connector 4 through the movable sleeve 504; It should also be noted that if Figure 5 As shown, when the connector 4 and the interface 2 are not initially plugged in, the opposing surfaces of the abutment plate 511 and the push plate 507 abut against each other, and the abutment plate 511 is now engaged with the side wall of the mounting frame 501, so the position of the push plate 507 can be limited by the setting of the abutment plate 511, and the elastic telescopic column 506 is in a compressed state under the resisting action of the abutment plate 511; It should also be noted that if Figure 3 , Figure 4 as well as Figure 6 As shown, when the connector 4 and the interface 2 are not initially plugged in, the sealing plate 604 blocks the interface 2 to prevent external dust from entering the interior of the interface 2 and affecting the subsequent insertion and use of the connector 4, and the two arc-shaped locking plates 704 are symmetrically arranged on both sides of the moving sleeve 504 with the moving sleeve 504 as the axis.

[0032] The following is the working process of the centralized access mechanism 5 performing centralized access to the joint 4, and the opening and closing control mechanism 6 opening the blockage of the interface 2 while performing access to the joint 4: When using, Figure 1 and Figure 2 As shown, since the top cover plate 502 is snap-fitted on the mounting frame 501, the staff can first remove the top cover plate 502 from the mounting frame 501, and then plug the plug connected to the end of the wire 3 away from the connector 4 into the electric energy meter to be tested and calibrated, and the connector 4 at the other end of the wire 3 is used to plug into the interface 2 opened on the calibrator body 1, refer to Figure 3 , Figure 4 as well as Figure 5 As shown, since the mounting frame 501 is symmetrically fixed with fixing frames 510 on both sides, a butt plate 511 is rotatably provided on the fixing frame 510, and the butt plate 511 is initially engaged with the mounting frame 501, and a joystick 512 is fixedly provided at the lower end of the butt plate 511, the staff can drive the butt plate 511 to rotate around the fixing frame 510 as the axis by pushing the joystick 512, at which time the butt plate 511 and the mounting frame 501 will release the engaged connection relationship, and a push plate 507 is movably provided on the mounting frame 501, and the push plate 507 is slidably connected to the slide groove 509, and the butt plate 511 is in abutment with the opposite surface of the push plate 507, and during the rotation of the butt plate 511, the resistance applied by the butt plate 511 to the push plate 507 will gradually disappear.

When the abutment plate 511 releases the abutment effect on the push plate 507, the push plate 507 is driven to slide in the slide groove 509 in the direction away from the fixed plate 505 by the elastic effect of the elastic telescopic columns 506. A movable sleeve 504 is provided, and the movable sleeve 504 is fixedly connected to the joint 4. A linkage plate 508 is fixedly provided on the outer surface of the end of the movable sleeve 504 away from the calibrator body 1, and the lower end of the linkage plate 508 is fixedly connected to the push plate 507. As the push plate 507 moves, the linkage plate 508 will be driven to move synchronously in the direction of the calibrator body 1. At this time, the movable sleeve 504 will also slide synchronously on the bending plate 503 in the direction of the calibrator body 1, and the movable sleeve 504 is fixedly connected to the joint 4. Therefore, when the movable sleeve 504 moves, it will drive the joint 4 to move synchronously in the direction of the calibrator body 1. Figure 4 , Figure 7 as well as Figure 8As shown, a first connecting frame 601 is fixedly arranged on the outer surface of one end of the movable sleeve 504 away from the linkage plate 508, a second connecting frame 603 is fixedly arranged on the upper end of the sealing plate 604, and a first connecting plate 602 is rotatably arranged between the second connecting frame 603 and the first connecting frame 601. Therefore, when the push plate 507 pushes the movable sleeve 504 to slide on the bending plate 503 toward the direction of the calibration instrument body 1 through the linkage plate 508, the movable sleeve 504 will synchronously drive the first connecting frame 601 to move synchronously toward the calibration instrument body 1. At this time, under the linkage action of the first connecting plate 602, the second connecting frame 603 can be driven to move upward, and synchronous The sealing plate 604 is pulled to slide upward on the outer wall of the calibration instrument body 1, and the interface 2 blocked by the sealing plate 604 is exposed. When the sealing plate 604 moves upward, the connector 4 is synchronously inserted into the interface 2 to achieve the connection between the connector 4 and the interface 2. The abutment effect of the abutment plate 511 on the push plate 507 is released by pushing the joystick 512, and then the elastic resetting effect of the elastic telescopic column 506 is used to drive the push plate 507 and the movable sleeve 504 to move synchronously to achieve the automatic connection between the connector 4 and the interface 2. This automatic operation greatly reduces human intervention and reduces errors caused by improper operation or negligence, thereby improving the accuracy of the detection data. At the same time, since the interface 2 and the connector 4 are both provided in multiple numbers and the numbers correspond, the number of movable sleeves 504 provided is synchronously corresponding to the connector 4, and the push plate 507 is provided in a single number, and the push plate 507 is fixedly connected to the multiple movable sleeves 504 through the linkage plate 508. Therefore, when the push plate 507 releases the abutting force, it can drive the multiple movable sleeves 504 to synchronously penetrate the bending plate 503 and move toward the direction of the calibration instrument body 1 at one time, so that the connector 4 is pushed and inserted into the interior of the interface 2. When multiple wires 3 and connectors 4 need to be connected for error detection and verification of the electric energy meter, the staff does not need to operate them one by one, and the plug-in task between the connector 4 and the interface 2 can be completed in a centralized manner. The operation is relatively convenient and simple, and the wires 3 and connectors 4 can be effectively stored when not in use to prevent the wires 3 and connectors 4 from being lost or dirty. In this embodiment, the elastic resetting effect of the elastic telescopic column 506 on the push plate 507 can enable the push plate 507 to tightly insert the connector 4 into the interface 2, effectively preventing the connector 4 from being loosened and disengaged due to external force during the mutual plugging process with the interface 2, thereby increasing the plugging stability of the connector 4 and the interface 2, avoiding the error in the data results of the measurement error detection and verification of the electric energy meter, thereby improving the accuracy of the detection data and reducing the probability of repeated verification; In the above process, by setting the centralized access mechanism 5, the movable sleeve 504, the push plate 507, the elastic telescopic column 506 and the support plate 511 are used to cooperate with each other to achieve centralized access and unified management of the connector 4. This design makes it possible to quickly complete the plugging task of multiple connectors 4 and the interface 2 on the calibrator body 1 without the need for the staff to operate the wires 3 and connectors 4 one by one during the measurement error detection and calibration of the electric energy meter, thereby greatly improving the work efficiency. like Figure 4 and Figure 8 As shown, since the sealing plate 604 initially covers the interface 2, the interface 2 can be blocked when not in use to prevent external dust from entering the interior of the interface 2 and affecting the subsequent insertion and use of the connector 4, thereby ensuring the cleanliness of the interface 2 and avoiding poor connection or damage to the connector 4 due to impurity contamination, thereby ensuring the connection quality between the calibrator body 1 and the electric energy meter. By pushing the movable sleeve 504 with the push plate 507, the sealing plate 604 can be synchronously driven and opened by utilizing the linkage effect of the first connecting plate 602 while driving the connector 4 to be plugged into the interface 2, thereby releasing the sealing plate 604 from covering the interface 2, thereby achieving a quick response during use, allowing the connector 4 to be quickly inserted into the interface 2, reducing the risk of damage to the sealing plate 604 or contamination of the interface 2 due to improper manual operation, effectively reducing the maintenance cost of the equipment, and helping to extend the service life of the calibrator body 1 and the electric energy meter; In this process, by setting the opening and closing regulating mechanism 6 and using the pushing setting of the push plate 507 on the movable sleeve 504, the function of synchronously driving and opening the sealing plate 604 is realized while the joint 4 is plugged into the interface 2. This design makes it unnecessary for the staff to operate the opening and closing of the sealing plate 604 separately, thereby simplifying the operation process and improving the operation efficiency. In addition, positioning the end of the connector 4 at the interface 2 and coordinating with the design of automated operation can reduce the difficulty of the calibration process, so that non-professionals can also easily complete the calibration work, thereby eliminating the need to pre-match the connector 4 and the interface 2 when using, thereby saving calibration preparation time and improving calibration efficiency; Please refer to the above working process Figures 1 to 8 .

[0033] The following is the working process of the locking control mechanism 7 locking the connector 4 while opening the interface 2: In the above description, the push plate 507 pushes the movable sleeve 504 to slide through the bending plate 503 in the direction of the calibration instrument body 1, so that the sealing plate 604 moves open and the connector 4 is inserted into the interface 2. Figure 6 and Figure 8As shown, since the upper end of the sealing plate 604 is symmetrically fixed with an ear plate 701, an L-shaped driven plate 703 is symmetrically slidably arranged between the calibrator body 1 and the bending plate 503, and a second connecting plate 702 is rotatably arranged between the L-shaped driven plate 703 and the ear plate 701, as the sealing plate 604 moves upward, the ear plate 701 moves upward synchronously, and under the linkage action of the second connecting plate 702, the two L-shaped driven plates 703 can be driven to move toward each other (that is, move toward the center position of the joint 4), as shown in FIG. Figure 6 As shown, since arc-shaped locking plates 704 are symmetrically arranged on both sides of the movable sleeve 504, and the side of the arc-shaped locking plates 704 away from the calibration instrument body 1 is slidably connected to the bending plate 503, and the arc-shaped locking plates 704 are fixedly connected to the L-shaped driven plate 703, as the two L-shaped driven plates 703 move toward each other, the two arc-shaped locking plates 704 can be synchronously driven to slide on the bending plate 503 in the direction of the outer surface of the movable sleeve 504, and finally after the joint 4 and the interface 2 are plugged in, the two arc-shaped locking plates 704 can be tightly fitted on the outer surface of the movable sleeve 504, and the position of the movable sleeve 504 is locked and restricted, so as to prevent the movable sleeve 504 from sliding on the bending plate 503 during the process of the calibration instrument body 1 detecting and calibrating the measurement error of the external electric energy meter, thereby increasing the stability of the detection process and improving the data accuracy; In the above process, by setting the locking control mechanism 7, while opening the interface 2, the linkage effect of the second connecting plate 702 can be utilized to cooperate with the L-shaped driven plate 703 to drive the two arc-shaped locking plates 704 to move toward each other, and the connector 4 is locked synchronously. This design can not only prevent the connector 4 from loosening during the plug-in use with the interface 2, but also ensure the signal transmission quality between the calibration instrument body 1 and the electric energy meter, thereby ensuring the accuracy of the calibration data. At the same time, the locking of the connector 4 by the arc-shaped locking plate 704 reduces the risk of misoperation caused by improper manual operation, effectively ensures the stable connection between the calibration instrument body 1 and the electric energy meter, thereby reducing the risk of equipment damage caused by poor connection, helping to improve the durability of the equipment, and reducing the maintenance cost caused by frequent replacement of damaged parts. In addition, through the linkage between the various mechanisms, it is different from the cumbersome operation of opening the interface 2 and limiting the connector 4 to two independent steps in a separate manner, which can greatly improve the efficiency of the operation; Please refer to the above working process Figures 1 to 8 .
