Description

Technical Field

[0001] The present invention relates to the technical field of electricity meter detection, and particularly relates to an automatic connection device for electricity meter detection and a using method thereof. Background Art

[0002] With the increasing development of smart grids, the demand for intelligent user terminals in various countries is also increasing day by day. Smart electricity meters should meet the national requirements for their dielectric quality. Under normal use conditions, in order to ensure the safe use of the meter and its auxiliary devices connected thereto, the meter and its auxiliary safety devices connected thereto should meet sufficient dielectric quality. In this regard, the national standard GB / T17215.211-2006 makes relevant regulations on the dielectric quality of the meter, and at the same time explains the scope of the insulation performance test. According to the relevant regulations on the dielectric quality of the meter in GB / T17215.211-2006, the dielectric quality tests for smart electricity meters include: impulse voltage test and alternating voltage test. The impulse voltage test includes the test between lines and the test of all lines to the ground; the alternating voltage test includes the test of all lines to the ground.

[0003] Currently, in the insulation test of single-phase smart electricity meters, wiring is usually carried out manually and the test is carried out in the way of testing a single meter each time. The test takes a lot of time and manpower, and there are problems such as cumbersome work and low efficiency. And manual wiring has problems such as easy wiring errors, poor contact, and poor safety. At the same time, the detection column is generally in the extended state, and it is easy to damage the detection column when not in use, and the operator is easy to touch it by mistake, thus causing unnecessary danger. Facing the above problems, there is an urgent need for a device that can safely and efficiently implement the insulation test of electricity meters. Summary of the Invention

[0004] In order to solve the problems existing in the above-mentioned prior art, an automatic connection device for electricity meter detection and a using method thereof are provided.

[0005] The technical solution adopted by the present invention to solve its technical problems is:

[0006] The present invention provides an automatic connection device for electricity meter detection, which includes a fixed platform. A detection base and a tray for placing the electricity meter are slidably connected to the fixed platform. A limit seat is fixedly connected inside the detection base, and a limit rod is slidably connected to the limit seat. One end of the limit rod is connected with a scroll spring, and the other end of the limit rod is hinged with a flipping seat. A detection column for detecting the electricity meter is connected inside the flipping seat. The flipping seat is also hinged with a rotating connecting rod, and the other end of the rotating connecting rod is rotatably connected to the detection base through a fixed rotating shaft. A flipping ejector rod is also slidably connected inside the detection base. One end of the flipping ejector rod is in contact with the limit rod, and the other end of the flipping ejector rod is connected to the tray through a spring.

[0007] Preferably, in the initial state, the flipping seat drives the detection column to be in a vertical state; when the flipping ejector rod drives the limit rod to contact the limit seat, the limit rod drives the flipping seat to rotate so that the detection column is in a horizontal state.

[0008] Preferably, the tray is provided with positioning holes, and a guiding ejector rod is slidably arranged in the positioning holes. The guiding ejector rod is fixedly connected to the flipping ejector rod. The spring is sleeved on the guiding ejector rod, and the spring is arranged outside the tray. One end of the spring is connected to the flipping ejector rod, and the other end of the spring is connected to the tray.

[0009] Preferably, the fixed platform is also rotatably connected with a gear. The detection base is fixedly connected with a detection rack, and the tray is fixedly connected with a tray rack. The tray rack and the detection rack are arranged on both sides of the gear and are both meshed with the gear.

[0010] Preferably, through holes are further opened on both sides of the detection base. A locking spring is arranged in the through holes. One end of the locking spring is connected with a locking steel ball, and the other end of the locking spring is connected with a movable block. The tray rack is also provided with a plurality of arc grooves adapted to the locking steel balls.

[0011] Preferably, the detection base is fixedly connected with a guiding seat, and the tray is fixedly connected with a guiding rod. The guiding rod and the guiding seat are slidably connected, and the guiding rod is fixedly connected with a locking block adapted to the movable block.

[0012] Preferably, the contact surface between the locking block and the movable block is an inclined surface; when the detection column is in a horizontal state, the tray rack is meshed with the gear.

[0013] The present invention also provides a usage method of an automatic connection device for electricity meter detection. Using the above-mentioned automatic connection device for electricity meter detection, it includes the following steps:

[0014] S1: Place the electricity meter on the tray, then drive the tray to move towards the detection base. The tray drives the flipping ejector rod to move, and further drives the limit rod to move. At this time, the spring is in a compressed state;

[0015] S2: As the limit rod moves, the limit rod drives the flipping seat to rotate. The flipping seat drives the rotating connecting rod to rotate around the fixed rotating shaft, and the flipping seat drives the detection column to rotate;

[0016] S3: As the limit rod continues to move, when the limit rod contacts the limit seat, the limit rod drives the flipping seat to rotate so that the detection column is in a horizontal state. Then continue to push the tray to connect the electricity meter with the detection column for subsequent detection work of the electricity meter;

[0017] S4: After the detection is completed, drive the tray to move away from the detection base. Under the action of the spring, the reset work of the tray is realized. Under the action of the volute spring, the limit rod resets and drives the detection column to rotate to the initial state.

[0018] Preferably, in step S3, as the tray continues to move, when the tray rack engages with the gear, the gear drives the detection rack to move, so that the detection base moves towards the electricity meter, thereby realizing the connection work between the electricity meter and the detection column. During this process, the guiding ejector rod slides in the positioning hole.

[0019] Preferably, when the locking block contacts the movable block, the locking block drives the movable block to move towards the tray rack. At this time, the locking spring is compressed, so that the locking steel ball contacts the arc groove of the tray rack to realize the relative fixation of the tray position.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. The detection column provided in the present invention is set in the vertical direction in the initial state. When the tray moves, after driving the limit rod to contact the limit seat, the detection column becomes horizontal, which is beneficial to the subsequent connection work of the electricity meter and the protection work of the detection column. When not in use, the detection column is stored, effectively preventing the operator from accidentally touching it or damaging the detection column during movement. The operation is convenient, the safety factor is high, and it is beneficial to the protection of the detection column itself. During the connection process of the electricity meter, the operator will never contact the detection column, effectively preventing the occurrence of electric shock and other situations, and has extremely high promotion value.

[0022] 2. In the present invention, through the commutation function of the gear, when the electricity meter moves, the detection base drives the detection columns to move towards each other, which is conducive to the connection work between the detection columns and the electricity meter. And when the locking block contacts the movable block, because the contact surface is an inclined plane, it will drive the movable block to move and compress the locking spring. The locking steel ball cooperates with the tray rack to fix the tray. Therefore, only by driving the tray to move, not only can the detection column be extended, but also the automatic fixation of the tray can be realized. The structure is reasonable, the operation is simple, and it is safe to use, effectively improving the efficiency and quality of electricity meter detection. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] As Figures 1-4 shown, this embodiment provides an automatic connection device for electricity meter detection, including a fixed platform 1. A detection base 2 and a tray 13 for placing an electricity meter 11 are slidably connected to the fixed platform 1. A limiting seat 5 is fixedly connected inside the detection base 2, and a limiting rod 3 is slidably connected to the limiting seat 5. The limiting rod 3 penetrates through the limiting seat 5.

[0031] One end of the limiting rod 3 is connected with a volute spring 4, and the other end of the limiting rod 3 is hinged with a flipping seat 8; a detection column 9 for detecting the electricity meter 11 is connected inside the flipping seat 8. The flipping seat 8 is also hinged with a rotating connecting rod 7, and the other end of the rotating connecting rod 7 is rotatably connected to the detection base 2 through a fixed rotating shaft 6.

[0032] The structure of the limiting rod 3 is as shown in Figure 4 Figure 1. The left end of the limiting rod 3 is connected with a volute spring 4, and the volute spring 4 is connected with the detection base 2 to realize the reset of the limiting rod 3. The right end of the limiting rod 3 is connected with a fixing plate. When the fixing plate at the right end of the limiting rod 3 contacts the limiting seat 5, the limiting rod 3 cannot move to the left at this time. The limiting seat 5 plays a role in limiting the movement of the limiting rod 3. On the other hand, under the action of the limiting seat 5, it prevents the limiting rod 3 from moving too far to the left. The flipping seat 8 is also provided with a channel for the wire to pass through, and the wire contacts the detection column 9, and the connection of the electric energy meter 11 is realized through the wire.

[0033] The fixed rotating shaft 6 is fixedly connected with the detection base 2, the rotating connecting rod 7 is rotatably connected with the fixed rotating shaft 6, and the left end of the flipping seat 8 is hinged with the limiting rod 3, and the bottom end of the flipping seat 8 is hinged with the rotating connecting rod 7. Therefore, when the flipping seat 8 rotates, the rotating connecting rod 7 will rotate around the fixed rotating shaft 6, and the fixed rotating shaft 6 plays a role in limiting the rotation of the rotating connecting rod 7, so that the rotating connecting rod 7 makes a circular motion with the fixed rotating shaft 6 as the center. The rotating connecting rod 7 plays a role in limiting the movement of the flipping seat 8, and because the left end of the flipping seat 8 remains unchanged under the action of the limiting rod 3, the flipping seat 8 will rotate around the hinge point with the limiting rod 3.

[0034] A flipping ejector rod 10 is also slidably connected in the detection base 2. One end of the flipping ejector rod 10 contacts the limiting rod 3. The flipping ejector rod 10 penetrates through the outer wall of the detection base 2, and the other end of the flipping ejector rod 10 passes through the detection base 2 and is connected with the tray 13 through a spring 15.

[0035] In the initial state, the flipping seat 8 drives the detection column 9 to be in a vertical state; when the flipping ejector rod 10 drives the limiting rod 3 to contact the limiting seat 5, the limiting rod 3 drives the flipping seat 8 to rotate so that the detection column 9 is in a horizontal state.

[0036] Therefore, in the present invention, the detection column 9 has two states. One is the vertical state, at this time the detection column 9 moves into the detection base 2. The detection base 2 realizes the protection of the detection column 9. When not in use, the detection column 9 is stored, effectively preventing the operator from accidentally touching it, or damaging the detection column 9 during movement. The operation is convenient, the safety factor is high, and it is beneficial to the protection of the detection column 9 itself. During the connection process of the electric energy meter 11, the operator will never contact the detection column 9, effectively preventing the occurrence of electric shock and other situations, and has extremely high promotion value.

[0037] The tray 13 is provided with a positioning hole 12, a guiding ejector rod 14 is slidably arranged in the positioning hole 12, and the guiding ejector rod 14 is fixedly connected with the flipping ejector rod 10; the spring 15 is sleeved on the guiding ejector rod 14, the spring 15 is arranged outside the tray 13, one end of the spring 15 is connected with the flipping ejector rod 10, and the other end of the spring 15 is connected with the tray 13.

[0038] The fixed platform 1 is also rotatably connected with a gear 17, the detection base 2 is fixedly connected with a detection rack 18, and the tray 13 is fixedly connected with a tray rack 16. The tray rack 16 and the detection rack 18 are arranged on both sides of the gear 17 and are both meshed with the gear 17.

[0039] The gear 17 plays a role in reversing. Under the action of the gear 17, when the tray rack 16 moves to the left, it can drive the detection rack 18 to move to the right, thereby driving the electric energy meter 11 and the detection base 2 to move towards each other.

[0040] Through holes are also formed on both sides of the detection base 2. A locking spring 22 is arranged in the through hole. One end of the locking spring 22 is connected with a locking steel ball 23, and the other end of the locking spring 22 is connected with a movable block 21. The tray rack 16 is also provided with a plurality of arc grooves adapted to the locking steel balls 23.

[0041] Since the tray rack 16 has arc grooves and there are a plurality of such arc grooves, when the locking steel ball 23 moves into the arc groove, if the locking block 24 and the movable block 21 do not contact at this time, as the tray 13 moves, the locking steel ball 23 can slide in the arc groove to make the locking steel ball 23 move to a suitable position in the arc groove.

[0042] The arc groove plays a role in limiting the movement of the tray 13. When the locking steel ball 23 contacts the leftmost arc groove, it will exert a resistance on the movement of the tray 13 at this time, preventing the tray 13 from moving too much distance at one time. Therefore, it effectively prevents the tray 13 from moving excessively, so that the electric energy meter 11 contacts the detection column 9 too much and is damaged.

[0043] The detection base 2 is fixedly connected with a guide seat 20, the tray 13 is fixedly connected with a fixed seat 25, the fixed seat 25 is fixedly connected with a guide rod 19, the guide rod 19 is slidably connected with the guide seat 20, and the guide rod 19 is fixedly connected with a locking block 24 adapted to the movable block 21. The guide seat 20 and the guide rod cooperate to further limit the tray 13.

[0044] The contact surface between the locking block 24 and the movable block 21 is an inclined surface; when the detection column 9 is in a horizontal state, the tray rack 16 and the gear 17 are meshed.

[0045] The bottom surface of the locking block 24 is an inclined surface, which is adapted to the inclined surface of the movable block 21. The purpose of setting it as an inclined surface is that, on the one hand, it is convenient for the locking block 24 to drive the movable block 21 to move in the direction of the locking steel ball 23 when they come into contact. On the other hand, the inclined surface structure is similar to two wedge blocks. Therefore, when the locking block 24 is in close contact with the movable block 21, due to the limiting effect of the guide rod 19 on the movement of the locking block 24, the locking block 24 can only move horizontally. Thus, the locking work between the locking block 24 and the movable block 21 can be achieved to prevent displacement of the locking block 24 and the movable block 21; and the inclined surface structure is beneficial to the subsequent unlocking work. When the tray 13 moves to the right, under the action of this inclined surface, the locking block 24 and the movable block 21 can be quickly separated without affecting the normal movement of the movable block 21.

[0046] The present invention also proposes a usage method of an automatic connection device for watt-hour meter detection. Using the above-mentioned automatic connection device for watt-hour meter detection, it includes the following steps:

[0047] S1: Place the watt-hour meter 11 on the tray 13, and then drive the tray 13 to move in the direction close to the detection base 2. The tray 13 drives the flipping ejector rod 10 to move, and further drives the limiting rod 3 to move. At this time, the spring 15 is in a compressed state;

[0048] S2: As the limiting rod 3 moves, the limiting rod 3 drives the flipping seat 8 to rotate. The flipping seat 8 drives the rotating link 7 to rotate around the fixed rotating shaft 6, and the flipping seat 8 drives the detection column 9 to rotate;

[0049] S3: As the limiting rod 3 continues to move, when the limiting rod 3 contacts the limiting seat 5, the limiting rod 3 drives the flipping seat 8 to rotate so that the detection column 9 is in a horizontal state. Then continue to push the tray 13 to connect the watt-hour meter 11 with the detection column 9 for subsequent detection work of the watt-hour meter 11;

[0050] S4: After the detection is completed, drive the tray 13 to move in the direction away from the detection base 2. Under the action of the spring 15, the reset work of the tray 13 is realized. Under the action of the volute spring 4, the limiting rod 3 is reset, driving the detection column 9 to rotate to the initial state.

[0051] In step S3, as the tray 13 continues to move, when the tray rack 16 meshes with the gear 17, the gear 17 drives the detection rack 18 to move, causing the detection base 2 to move in the direction close to the watt-hour meter 11, thereby realizing the connection work between the watt-hour meter 11 and the detection column 9. During this process, the guiding ejector rod 14 slides in the positioning hole 12.

[0052] When the locking block 24 contacts the movable block 21, the locking block 24 drives the movable block 21 to move towards the pallet rack 16. At this time, the locking spring 22 is compressed, so that the locking steel ball 23 contacts the arc groove of the pallet rack 16, realizing the relative fixation of the position of the pallet 13.

[0053] It should be noted that the guiding ejector rod 14 cooperates with the positioning hole 12 to limit the movement of the pallet 13. At the same time, in the initial state, the pallet rack 16 does not mesh with the gear 17. Only when the detection column 9 rotates to the horizontal state, at this time, because the limiting rod 3 and the limiting seat 5 are in close contact, the limiting rod 3 cannot move further, and the flipping ejector rod 10 cannot move further either. At this time, the guiding ejector rod 14 slides freely in the positioning hole 12, so that the spring 15 is compressed, and at this time, the pallet rack 16 starts to mesh with the gear 17.

[0054] When the guiding ejector rod 14 drives the flipping ejector rod 10 to rotate through the spring 15, the limiting rod 3 only needs to move a small distance to drive the detection column 9 to rotate a large angle, and the elastic force of the scroll spring 4 is less than the elastic force of the spring 15. Therefore, when the pallet 13 moves, the flipping ejector rod 10 is driven to move leftward through the spring 15. At this time, the elastic force of the scroll spring 4 needs to be overcome. Therefore, the spring 15 only needs to be compressed by a short length to realize the movement of the flipping ejector rod 10 driven by the pallet 13.

[0055] In addition, when the pallet rack 16 meshes with the gear 17, at this time, the spring 15 is in a state of being compressed by a certain length. Therefore, it is necessary to detect that the base 2 and the electric energy meter 11 move towards each other. Compared with the way that the base 2 does not move, in this way, the electric energy meter 11 only needs to move half of the distance to realize the cooperation between the electric energy meter 11 and the detection column 9.

[0056] In addition, after the electric energy meter 11 finishes the detection, it drives the pallet 13 to move rightward, separating the locking block 24 from the movable block 21. In this way, the unlocking of the pallet rack 16 by the locking steel ball 23 is realized. Under the action of the spring 15, the reset work of the pallet 13 is realized, and at the same time, under the action of the scroll spring 4, the flipping and storage work of the detection column 9 is realized.

[0057] Therefore, only by driving the movement of the pallet 13, not only can the extension of the detection column 9 be realized, but also the automatic fixation of the pallet 13 can be realized, which is convenient for the cooperation between the electric energy meter 11 and the detection column 9. The structure is reasonable, the operation is simple, and the use is safe, effectively improving the efficiency and quality of the electric energy meter detection.
