[0002] An energy meter is a meter that measures electrical energy, also known as an electric meter or kilowatt-hour meter. It calculates and monitors electricity consumption by measuring the use of electrical energy. There are many types of energy meters according to their structure and purpose. For example, they can be divided into mechanical energy meters and electronic energy meters according to their working mode. Mechanical energy meters use the principle of mechanical rotation to record the consumption of electrical energy through a counter; electronic energy meters use electronic technology and integrated circuits to achieve more accurate measurement and intelligent management.

[0003] Electricity meters need to be calibrated before leaving the factory. In the prior art, the automated calibration process of electricity meters has basically been realized. However, the automated calibration system of electricity meters in the prior art is usually based on the pneumatic system to control various actions. When wiring the system, it is necessary to design and install relatively complex pneumatic pipelines, and correspondingly, a large number of pneumatic components such as jacking cylinders will be used, which leads to a high overall installation design cost of the system, and the subsequent maintenance and overhaul process is also relatively complicated.

[0007] Material toggling mechanism, comprising two sliding rods symmetrically arranged at the bottom of the positioning plate, and two connecting seats symmetrically arranged on both sides of the positioning plate. The positioning plate is also provided with a connecting component for adjusting the connection state between the positioning plate and the sliding rod. A plurality of first springs are connected between the sliding rod and the side wall of the positioning plate. A plurality of transmission links are rotatably installed on the bottom wall of each of the sliding rods, and the end of the transmission link away from the sliding rod is rotatably installed on the top of the connecting plate. One side of the connecting seat is connected to the first mounting plate, and an adjusting link is provided on the other side of the connecting seat. The connecting seat is provided with a guide groove in the vertical direction for the sliding of the adjusting link, and a limiting component for fixing the adjusting link in the guide groove is also provided in the guide groove, and the end of the adjusting link away from the connecting seat is connected to the side wall of the sliding rod.

[0008] According to a further technical solution, the connecting component includes an installation groove provided in the sliding rod, a connecting block is slidably installed in the installation groove along the vertical direction, and the bottom of the connecting block is connected to the bottom wall of the installation groove through a second spring, a limiting hole matching the connecting block is provided on the positioning plate, an adjusting block is also provided above the limiting hole, and an electric telescopic rod is also provided on the positioning plate for driving the adjusting block to move along the opening direction of the limiting hole.

[0009] According to a further technical solution, two positioning seats for placing the mounting tray are provided on the upper surface of the positioning plate, which can be used to connect and fix the mounting tray so that the mounting tray can be stably placed on the positioning plate, and the electric telescopic rod and the adjustment block are both installed in the positioning seats, without the need to set up additional mounting structures, thereby making the structure of the connecting assembly more compact and simpler.

[0010] According to a further technical solution, the limit assembly includes a limit tooth plate arranged in the guide groove, and one end of the adjusting connecting rod located in the guide groove is provided with a limit tooth segment cooperating with the limit tooth plate, a plurality of third springs are arranged between the limit tooth plate and the guide groove, and an electromagnet is also arranged in the guide groove for adjusting the connection state between the limit tooth plate and the limit tooth segment.

[0011] According to a further technical solution, the limit assembly also includes a push switch installed at the bottom of the installation groove, and the start and stop states of the electromagnet can be controlled by the push switch.

[0012] Another object of an embodiment of the present invention is to provide an operation method of an electric energy meter automatic verification system, based on the above-mentioned electric energy meter automatic verification system, comprising the following steps:

At this time, the lifting cylinder continues to push the connection plate upward, and the connection plate can drive the two sliding rods at the bottom of the same positioning plate to move towards each other through the transmission connecting rod. The sliding rod can pull the connection seat to move toward the side close to the positioning plate through the adjusting connecting rod, and the connection seat can drive the first mounting plate to move synchronously toward the side close to the positioning plate, so that the detector on the first mounting plate is inserted into the electric energy meter to realize the detection of the electric energy meter.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0031] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0032] like Figure 1-Figure 6As shown, an automatic verification system for electric energy meters provided by an embodiment of the present invention includes a rack 1, two rows of detection module mounting frames 11 are symmetrically arranged on the top of the rack 1, and each row includes a plurality of detection module mounting frames 11 distributed equidistantly, and detection modules 2 for detecting electric energy meters 31 are installed on the detection module mounting frames 11, and at least two layers of detectors 22 are arranged on the detection modules 2 and each of the detection module mounting frames 11; and further includes:

[0033] A driving mechanism 4, the driving mechanism 4 comprises a second mounting plate 41 mounted on the frame 1, a lifting cylinder 42 is mounted at the bottom of the second mounting plate 41, the lifting cylinder 42 is placed in a vertical direction, and its telescopic end faces upward, a connecting plate 43 is connected to the telescopic end of the lifting cylinder 42, and a guide rod 44 is slidably mounted on the second mounting plate 41 in a vertical direction, and the connecting plate 43 is slidably mounted on the guide rod 44 in a vertical direction, and a positioning plate 45 is also connected to the top of the guide rod 44;

[0034] The connecting mechanism 5 includes two sliding rods 52 symmetrically arranged at the bottom of the positioning plate 45, and two connecting seats 55 symmetrically arranged on both sides of the positioning plate 45. The sliding rods 52 are slidably installed in the sliding grooves arranged on the bottom wall of the positioning plate 45 along the direction toward the detection module mounting frame 11, and the positioning plate 45 is also provided with a connecting component 6 for adjusting the connection state between the positioning plate 45 and the sliding rods 52. A plurality of first springs 53 are connected between the sliding rods 52 and the side walls of the positioning plate 45. In the free state, the elastic force of the first springs 53 causes the sliding rods 52 to move closer to the middle of the positioning plate 45. Position movement, at the same time, a plurality of transmission connecting rods 51 are rotatably installed on the bottom wall of each sliding rod 52, and the end of the transmission connecting rod 51 away from the sliding rod 52 is rotatably installed on the top of the connecting plate 43, one side of the connecting seat 55 is connected to the first mounting plate 21, and the other side of the connecting seat 55 is provided with an adjusting connecting rod 54, and the connecting seat 55 is provided with a guide groove 56 for sliding the adjusting connecting rod 54 in the vertical direction, and a limiting component 7 for fixing the adjusting connecting rod 54 in the guide groove 56 is also provided in the guide groove 56, and the end of the adjusting connecting rod 54 away from the connecting seat 55 is connected to the side wall of the sliding rod 52.

[0035] In the embodiment of the present invention, when in use, a conveying line or a conveying device such as a loading and unloading manipulator can be used to queue and convey the installation tray 3 with the electric energy meter 31 installed to between the two rows of detection module mounting frames 11. In order to achieve efficient and rapid detection, a plurality of electric energy meters 31 can be installed in pairs on each installation tray 3, and the two electric energy meters 31 in each pair correspond to the two rows of detection module mounting frames 11 on both sides. When the installation tray 3 moves to the positioning plate 45, the lifting cylinder 42 can be controlled to extend, and the lifting cylinder 42 drives the connecting plate 43 to move upward. In the initial state, the connecting assembly 6 can fix the sliding rod 52 at a fixed position at the bottom of the positioning plate 45, and the connecting plate 43 can drive the positioning plate 45 to move upward synchronously through the transmission connecting rod 51. In this process, the transmission connecting rod 51 can drive the guide rod 44 to slide up and down synchronously along the second mounting plate 41, thereby ensuring the stability of the positioning plate 45 during the lifting and lowering movement. At the same time, the sliding rod 52 can drive the adjustment connecting rod 54 to slide synchronously in the mounting groove 65. When the positioning plate 45 drives the electric energy meter 31 to move to the specified height (i.e., after the electric energy meter 31 of the corresponding type is transported to the height position where the corresponding detector 22 is located), the connection component 6 is adjusted so that the sliding rod 52 is separated from the fixed connection state with the positioning plate 45. At the same time, after receiving the feedback from the connection component 6, the limit component 7 can work synchronously, thereby fixing the adjustment link 54 at a fixed height in the guide groove 56, and ensuring that the height position of the positioning plate 45 remains unchanged. At this time, the lifting cylinder 42 continues to extend. Since the height position of the positioning plate 45 is fixed, at this time, under the push of the connection plate 43, the transmission link 51 can drive the two sliding rods 52 at the bottom of the same positioning plate 45 to move towards each other, and the sliding rod 52 can pull the connecting seat 55 to move toward the side close to the positioning plate 45 through the adjustment link 54. The connecting seat 55 can drive the first mounting plate 21 to move synchronously toward the side close to the positioning plate 45, so that the detector 22 on the first mounting plate 21 is inserted into the electric energy meter 31 to detect the electric energy meter 31. After the detection is completed, the lifting cylinder 42 is retracted, and the corresponding control connection component 6 and the limit component 7 are started in the specified state (that is, the aforementioned detection process is reversed), so that the electric energy meter 31 can be restored to the initial position, and the detection of a batch of electric energy meters 31 is completed.

[0036] like Figure 1-Figure 3As shown, as a preferred embodiment of the present invention, the detection module 2 includes a first mounting plate 21, the first mounting plate 21 is slidably mounted on a slide rail 23 provided on the detection module mounting frame 11, and each first mounting plate 21 on the same detection module mounting frame 11 is connected to the same connection seat 55, and a detector 22 for detecting an electric energy meter 31 is mounted on the first mounting plate 21, and the detectors 22 in each layer of the detection modules 2 on the same detection module mounting frame 11 are different, and the height of the mounting tray 3 can be adjusted so that the electric energy meter 31 is located at a height corresponding to a specified layer, so that it corresponds to the corresponding detector 22, and such electric energy meter 31 can be detected, and different layers meet the detection requirements of different types of electric energy meters 31, thereby realizing the detection of multiple types of electric energy meters 31. At the same time, the detectors 22 in the same layer corresponding to each detection module mounting frame 11 are the same, so that multiple electric energy meters of the same type can be detected at the same height position.

[0037] In the embodiment of the present invention, when in use, the two symmetrically arranged connecting seats 55 can drive the first mounting plates 21 on the two opposite detection module mounting frames 11 to slide toward each other along the slide rail 23, thereby driving the detector 22 to move toward the side close to the electric energy meter 31 through the first mounting plate 21, so that the detector 22 can be plugged into the specified position of the electric energy meter 31 to realize the detection of the electric energy meter 31.

[0038] As a preferred embodiment of the present invention, when the sliding rod 52 slides from the edge of the positioning plate 45 to the middle of the positioning plate 45, the elastic force provided by the first spring 53 can make the sliding rod 52 maintain a tendency to move toward the middle of the positioning plate 45, and will not move toward the edge of the positioning plate 45. Alternatively, a limiting protrusion can be provided on the side wall of the sliding groove opened on the bottom wall of the positioning plate 45, and in the initial state, the sliding rod 52 abuts against the limiting protrusion, thereby preventing the sliding rod 52 from sliding toward the side wall of the positioning plate 45 during the subsequent sliding process.

[0039] like Figure 5 and Figure 6As shown, as a preferred embodiment of the present invention, each of the sliding rods 52 is correspondingly provided with a group of connecting components 6. Specifically, the connecting component 6 includes a mounting groove 65 provided in the sliding rod 52, and a connecting block 61 is slidably installed in the mounting groove 65 along the vertical direction, and the bottom of the connecting block 61 is connected to the bottom wall of the mounting groove 65 through a second spring 66. A limiting plug hole 62 matching the connecting plug block 61 is provided on the positioning plate 45, and when the second spring 66 is in a free state, the connecting block 61 will be plugged into the limiting plug hole 62 under the elastic force of the second spring 66. An electric telescopic rod 63 is also provided on the positioning plate 45, and the electric telescopic rod 63 is vertically downwardly arranged. The movable end of the electric telescopic rod 63 is connected to an adjusting plug block 64, and the adjusting plug block 64 is located directly above the connecting plug block 61.

[0040] In the embodiment of the present invention, during specific operation, when the positioning plate 45 moves upward and causes the electric energy meter 31 to move to a specified height, the connecting block 61 is always inserted in the limiting plug hole 62 under the elastic force of the second spring 66 (and in this process, the connecting block 61 is not completely detached from the mounting groove 65). At this time, under the limiting action of the connecting block 61, the first spring 53 and the positioning plate 45 remain relatively still. When the electric energy meter 31 reaches the specified height, the electric telescopic rod 63 starts and extends. The electric telescopic rod 63 can drive the adjusting block 64 to move downward and insert the adjusting block 64 into the limiting socket 62. The adjusting block 64 can push the connecting block 61 out of the limiting socket 62 and make the limiting socket 62 completely retract into the mounting groove 65. At this time, the sliding rod 52 and the positioning plate 45 are only in abutment state. When the height position of the positioning plate 45 is locked, the movement of the connecting plate 43 along the vertical direction can be converted into the movement of the sliding rod 52 along the horizontal direction through the transmission connecting rod 51.

[0041] like Figure 5 and Figure 6 As shown, as a preferred embodiment of the present invention, the upper surface of the positioning plate 45 is provided with two positioning seats 46 for placing the mounting tray 3, which can be used to connect and fix the mounting tray 3 so that the mounting tray 3 is stably placed on the positioning plate 45, and the electric telescopic rod 63 and the adjustment block 64 are both installed in the positioning seat 46.

[0042] like Figure 7 and 8As shown, as a preferred embodiment of the present invention, the limiting assembly 7 includes a limiting tooth plate 71 arranged in the guide groove 56, the limiting tooth plate 71 is slidably installed in the guide groove 56 along the length direction of the adjusting link 54, and the end of the adjusting link 54 located in the guide groove 56 is provided with a limiting tooth segment 72 that cooperates with the limiting tooth plate 71, a plurality of third springs 73 are arranged between the limiting tooth plate 71 and the guide groove 56, and in a free state, the limiting tooth plate 71 is subjected to the elastic force of the third springs 73 and engages with the limiting tooth segment 72, and an electromagnet 74 is also arranged in the guide groove 56, and the limiting tooth plate 71 and the limiting tooth segment 72 can be controlled by controlling the start and stop of the electromagnet 74. The connection relationship between the segments 72, specifically, when the electromagnet 74 is turned on, the limit tooth plate 71 is attracted by the electromagnet 74 and moves to the side close to the electromagnet 74, at this time, the limit tooth plate 71 and the limit tooth segment 72 are out of the state of mutual engagement (the third spring 73 is correspondingly in a contracted state), and the adjusting link 54 can slide freely in the guide groove 56; when the electromagnet 74 is powered off and closed, under the action of the elastic restoring force of the third spring 73, the limit tooth plate 71 moves to the side close to the limit tooth segment 72, and makes the limit tooth plate 71 and the limit tooth segment 72 engage with each other, at this time, due to the limiting effect of the limit tooth plate 71, the adjusting link 54 is fixed at the specified position in the guide groove 56.

[0043] like Figure 6 As shown, as a preferred embodiment of the present invention, the limit assembly 7 also includes a push-type switch 75 installed at the bottom of the mounting groove 65, and the push-type switch 75 can control the start and stop states of the electromagnet 74. Specifically, when the connecting block 61 is out of contact with the push-type switch 75 (that is, when the corresponding positioning plate 45 and the sliding rod 52 are in a relatively static state), the electromagnet 74 is in a power-on and started state. When the connecting block 61 is retracted into the mounting groove 65, the bottom of the connecting block 61 will squeeze the push-type switch 75. At this time, the push-type switch 75 can control the electromagnet 74 to cut off the power, and the electromagnet 74 is in a closed state.

[0044] Another embodiment of the present invention provides an operation method of an automatic verification system for an electric energy meter, based on the above-mentioned automatic verification system for an electric energy meter, comprising the following steps:

[0045] Step 1: Use a conveying device to queue and convey the installation trays 3 with the electric energy meters 31 installed to between two rows of detection module installation racks 11, and place the corresponding positions of the installation trays 3 on the positioning plate 45;

[0046] Step 2: Control the lifting cylinder 42 to extend, and the lifting cylinder 42 drives the connecting plate 43 to move upward. In the initial state, the connecting assembly 6 can fix the sliding rod 52 at a fixed position at the bottom of the positioning plate 45, and the connecting plate 43 can drive the positioning plate 45 to move upward synchronously through the transmission connecting rod 51 until the positioning plate 45 drives the electric energy meter 31 to move to a specified height;

[0047] Step 3, start the connection component 6, so that the sliding rod 52 is out of the state of being fixedly connected with the positioning plate 45. At the same time, after receiving the feedback from the connection component 6, the limit component 7 works synchronously, thereby fixing the adjusting connecting rod 54 at a fixed height in the guide groove 56, thereby fixing the height position of the positioning plate 45. At this time, the lifting cylinder 42 continues to push the connection plate 43 upward, and the connection plate 43 can drive the two sliding rods 52 at the bottom of the same positioning plate 45 to move towards each other through the transmission connecting rod 51. The sliding rod 52 can pull the connecting seat 55 to move toward the side close to the positioning plate 45 through the adjusting connecting rod 54, and the connecting seat 55 can drive the first mounting plate 21 to move synchronously toward the side close to the positioning plate 45, so that the detector 22 on the first mounting plate 21 is inserted into the electric energy meter 31 to detect the electric energy meter 31;

[0048] Step 4: After the detection is completed, the aforementioned detection process is reversed so that the electric energy meter 31 returns to the initial position, and the detection of a batch of electric energy meters 31 is completed.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
