Description

Technical Field

[0001] The present invention relates to the technical field of electricity meter lead seal detection, and particularly to an intelligent electricity meter lead seal detection device. Background Art

[0002] In the post-production stage of intelligent electricity meters, lead sealing treatment needs to be carried out on the intelligent electricity meters, that is, a component similar to a buckle is applied to the outer shell of the intelligent electricity meter. Once the lead seal is correctly locked, it cannot be opened unless it is violently damaged (i.e., cut open), and the damaged lead seal cannot be reused. Moreover, each lead seal has a unique serial number identification to prevent users from stealing electricity or illegally modifying the intelligent electricity meter. After the electricity meter is produced, it is necessary to detect whether the length of the plumb bob of the lead seal from the electricity meter is appropriate. If the distance between the plumb bob and the electricity meter is relatively long, there will be a situation where it can be damaged by users. If the distance between the plumb bob and the electricity meter is relatively short, it will affect the removal and installation of the lead seal by power personnel. Also, the length of the connecting rope on the electricity meter lead seal varies according to different usage scenarios, and the length of the lead seal within the specified range will meet the requirements.

[0003] For example, an intelligent electricity meter lead seal detection device with the publication number CN117516441B makes the detection block drive the detection rod to slide outwards through the operation of the pushing cylinder to detect the length of the lead seal. During the detection process, the movement of the detection block makes the toothed rod move, drives the gear to rotate, and then drives the threaded sleeve to rotate, so that the threaded rod pushes the pressing plate to slide downwards, making the pressing plate squeeze the plumb bob of the lead seal. And before the squeezing, the piston plate will slide down along the inner wall of the piston cylinder, making the air jet hole blow air towards the surface of the plumb bob to clean the surface of the plumb bob, preventing impurities on the outer surface of the plumb bob from damaging the plumb bob when squeezing the plumb bob, achieving the detection of the distance between the plumb bob and the electricity meter, and being able to detect the hardness of the plumb bob, ensuring the quality of the electricity meter lead seal, thus preventing the occurrence of electricity theft to a certain extent. However, in actual use, the connecting rope of the lead seal is limited by inserting the detection rod into the connecting rope and the plumb bob. Subsequently, when pulling the connecting rope, the connecting rope is not limited on the detection rod and may break away from the detection rod. Moreover, if the detection rod moves after being inserted, at this time, the connecting rope may be in a bent state, and when pulling the connecting rope subsequently, the bent state of the connecting rope will affect the detection accuracy. Also, when detecting the length of the connecting rope, it can only be detected at a fixed length. If the length of the connecting rope is within the specified range, it is very likely not to meet the standard, affecting the detection quality, and there are certain usage defects.

[0004] Therefore, we propose an intelligent electricity meter lead seal detection device to solve the problems raised above. Summary of the Invention

[0028] By adopting the above technical solution, it is convenient to position the electric meter.

[0029] Compared with the prior art, the beneficial effect of the present invention is that: in the intelligent electric meter seal detection device, detection components are arranged on one side and below the movable plate, so that when detecting the length of the seal on the electric meter, the connecting rope on the seal can be prevented from falling off, which avoids affecting the detection work, and the bending amplitude of the connecting rope can be avoided from being too large, which avoids affecting the detection accuracy and improves the practicability;

[0030] 1. A detection component is provided on one side and below the movable plate. When detecting the length of the seal on the electric meter, place the side of the electric meter with the seal on the top, convey the electric meter through the conveyor belt. After the electric meter moves, it fits against the baffle, and the two centering rods can move the electric meter to the middle of the baffle. Then stop the conveyor belt and start the electric push rod to drive the movable plate to move down. After the movable plate moves down, one end of the L-shaped rod fits against the electric meter, aligning the seal on the electric meter with the two semi-circular seats. Then continue to lower the movable plate. At this time, when the movable plate descends and the L-shaped rod and the movable rod no longer move, the tension spring can be deformed. Then, through the cooperation of the driving gear and the toothed plate, the rotating shaft is driven to rotate. Through the meshing of the first bevel gear and the second bevel gear, the rotating gear is driven to rotate. After the rotating gear rotates, it drives the arc-shaped rod to rotate through meshing with the toothed ring. During the rotation of the arc-shaped rod, the arc-shaped strip slides inside the arc-shaped groove to support the movement of the arc-shaped rod, enabling the arc-shaped rod to retract into the semi-circular seat. When the support rod is about to contact the electric meter, stop the descent of the movable plate. Then start the driving motor to drive the bidirectional screw rod to rotate, causing the two movable seats to slide away from each other. One side of the movable seat can fit and slide against the movable plate for positioning, enabling the two semi-circular seats to contact the connecting rope on the seal. The plumb bob can be located above the semi-circular seat. Then, as the movable seat moves, one end of the L-shaped rod can leave the top surface of the electric meter. Then, under the action of the tension spring, the movable rod returns to its original position, and thus the arc-shaped rod can be reset, enabling the plumb bob on the seal to be above the semi-circular seat and the arc-shaped rod. As the two movable seats move away from each other, the connecting rope can be straightened, and the plumb bob can be above the semi-circular seat and the arc-shaped rod and will not easily fall off. If the movable seat moves a certain distance but does not reach the specified length range, the movable block slides on the fixed rod and stretches the telescopic spring, and the reading of the tension sensor changes. At this time, the length of the seal is too short and does not meet the requirements. When the movable block moves when the movable seat moves to the specified length range, the length of the seal meets the standard. At this time, the two movable seats can be made to move away from each other again to pull the seal and detect the stability of the plumb bob installation on the seal. If the reading of the tension sensor does not change after the movable seat moves a distance exceeding the specified maximum distance, it proves that the length of the seal is too long. After the detection, make the two movable seats move closer to raise the movable plate so that the L-shaped rod is above the electric meter. Then lower the movable rod to retract the arc-shaped rod, and the seal can be put down. It is more convenient to put down the seal. Through the detection component, when detecting the length of the seal on the electric meter, it is possible to prevent the connecting rope on the seal from falling off, avoid affecting the detection work, and avoid excessive bending of the connecting rope, thus avoiding affecting the accuracy of the detection and improving the practicability;

[0031] 2. Before detection, the positions of the two semi-circular seats are aligned with the seal position. If the seal position of the electricity meter changes, the knob can be rotated to drive the threaded rod to rotate. After the threaded rod rotates, it can drive the support rod to slide. The top of the support rod fits and slides with the movable frame, so as to limit the movement of the support rod, and the front and rear positions of the two support rods can be adjusted, which is convenient for subsequent detection and improves the practicability.

[0032] 3. Before detection, the push rod can be rotated to drive the rotating rod to rotate, so that the cam rotates. After the cam rotates, it can push the movable frame to move. After the movable frame moves, it can drive the positioning rod to move. After the positioning rod moves, it can compress the return spring and make the positioning block leave the mounting rod. Then the movable sleeve can be moved to adjust the position of the pointer. After adjustment, the rotating rod is released, and under the action of the return spring, the positioning rod and the positioning block are reset, and the return spring is in a compressed state. Through the reaction force, the positioning block fits the mounting rod to position the movable sleeve. By adjusting the position of the pointer on the movable plate according to the longest length of the seal connecting rope, the pointer can be moved to the longest position of the specified length of the seal, which is convenient for the staff to observe the moving displacement of the movable seat through the pointer.

[0050] A movable frame 210 is fixedly mounted at the bottom of the movable block 207. A support rod 212 is arranged at the bottom of the movable frame 210. Positioning frames 213 are symmetrically mounted below one side of the support rod 212. A semi-circular seat 214 is fixedly mounted between the two positioning frames 213. An arc-shaped rod 215 is slidably connected inside the semi-circular seat 214. Arc-shaped grooves 217 are symmetrically formed inside the inner side of the semi-circular seat 214. Arc-shaped strips 216 are symmetrically mounted on both sides of the arc-shaped rod 215. The arc-shaped strips 216 are slidably connected to the arc-shaped grooves 217;

[0051] A toothed ring 218 is fixedly mounted on the outer side of the arc-shaped rod 215. Limit frames 219 are symmetrically mounted on one side of the support rod 212 where the support rod 212 is located at the semi-circular seat 214. A rotating gear 220 is rotatably connected between the two limit frames 219. The rotating gear 220 is meshed with the toothed ring 218. One end of the rotating gear 220 passes through the upper limit frame 219 through a rotating shaft and is fixedly mounted with a first bevel gear 221;

[0052] A rotating shaft 222 is rotatably connected to the lower part of one side inside the support rod 212. A second bevel gear 223 is fixedly mounted at one end of the rotating shaft 222. The second bevel gear 223 is meshed with the first bevel gear 221. A driving gear 225 is fixedly mounted at the other end of the rotating shaft 222;

[0053] On one side of the support rod 212, above the driving gear 225, a support base 224 is fixedly installed. Inside the support base 224, a movable rod 226 is slidably connected. Below one side of the movable rod 226, a toothed plate 227 is fixedly installed. At the same time, the toothed plate 227 is meshed with the driving gear 225. Above the outside of the movable rod 226, a tension spring 228 is sleeved. The two ends of the tension spring 228 are respectively fixedly connected to the support base 224 and the movable rod 226. On the other side of the movable rod 226, an L-shaped rod 229 is fixedly installed. At the same time, a ball is hinged to the end of the L-shaped rod 229 far away from the movable rod 226.

[0054] On the rear side of the movable plate 104, rectangular blocks 106 are symmetrically installed. Inside the two rectangular blocks 106, sliding rods 107 are slidably connected. At the tops of the two sliding rods 107, limit blocks 108 are fixedly installed. At the bottoms of the two sliding rods 107, a baffle 109 is fixedly installed. On one side of the baffle 109, centering rods 110 are symmetrically installed.

[0055] Example 1: As Figures 1-7As shown, when detecting the length of the lead seal on the electricity meter, place the side of the electricity meter with the lead seal on top, convey the electricity meter through the conveyor belt 101. After the electricity meter moves, it fits against the baffle 109, and the two centering rods 110 can move the electricity meter to the middle of the baffle 109. Then stop the conveyor belt 101 from running, and start the electric push rod 103 to drive the movable plate 104 to move down. After the movable plate 104 moves down, one end of the L-shaped rod 229 fits against the electricity meter, aligning the lead seal on the electricity meter with the two semi-circular seats 214. Then make the movable plate 104 continue to descend. At this time, when the movable plate 104 descends and the L-shaped rod 229 and the movable rod 226 no longer move, the tension spring 228 can be deformed. Then, through the cooperation of the driving gear 225 and the toothed plate 227, the rotating shaft 222 is driven to rotate. Through the meshing of the first bevel gear 221 and the second bevel gear 223, the rotating gear 220 is driven to rotate. After the rotating gear 220 rotates, it drives the arc-shaped rod 215 to rotate through meshing with the toothed ring 218. During the rotation of the arc-shaped rod 215, the arc-shaped strip 216 slides inside the arc-shaped groove 217 to support the movement of the arc-shaped rod 215, enabling the arc-shaped rod 215 to retract into the semi-circular seat 214. Stop the descent of the movable plate 104 when the support rod 212 is about to contact the electricity meter. Then start the drive motor 203 to drive the bidirectional lead screw 202 to rotate, causing the two movable seats 204 to slide away from each other. One side of the movable seat 204 can fit and slide against the movable plate 104 for positioning, enabling the two semi-circular seats 214 to contact the connecting rope on the lead seal. The plumb bob can be located above the semi-circular seat 214. Then, as the movable seat 204 moves, one end of the L-shaped rod 229 can leave the top surface of the electricity meter. Then, under the action of the tension spring 228, the movable rod 226 is reset, and thus the arc-shaped rod 215 can be reset, enabling the plumb bob on the lead seal to be above the semi-circular seat 214 and the arc-shaped rod 215. As the two movable seats 204 move away, the connecting rope can be straightened, and the plumb bob can be above the semi-circular seat 214 and the arc-shaped rod 215 and will not easily come off. If the movable seat 204 moves a certain distance and does not reach the specified length range, the movable block 207 slides on the fixed rod 206 and stretches the telescopic spring 208, and the reading of the tension sensor 209 changes. At this time, the length of the lead seal is too short and does not meet the requirements. If the movable block 207 moves when the movable seat 204 moves to the specified length range, the length of the lead seal meets the standard. At this time, the two movable seats 204 can be made to move away again, enabling the lead seal to be pulled, and the stability of the installation of the plumb bob on the lead seal can be detected. If the reading of the tension sensor 209 does not change after the movable seat 204 moves a distance exceeding the specified maximum distance, it proves that the length of the lead seal is too long. After the detection, make the two movable seats 204 move closer to raise the movable plate 104 so that the L-shaped rod 229 is located above the electricity meter. Then make the movable rod 226 descend, enabling the arc-shaped rod 215 to retract, and the lead seal can be put down, which is more convenient for putting down the lead seal.By means of the detection component 2, when detecting the length of the lead seal on the electricity meter, the connecting rope on the lead seal can be prevented from falling off, which avoids affecting the detection work. Moreover, the excessive bending of the connecting rope can be avoided, which prevents affecting the detection accuracy and improves the practicability.

[0056] A threaded rod 211 is rotatably connected inside the movable frame 210, and the support rod 212 is threadedly connected to the threaded rod 211. One end of the threaded rod 211 passes through the movable frame 210 and is fixedly installed with a knob. At the same time, the top end of the support rod 212 is in contact with the movable frame 210.

[0057] Embodiment 2: As Figure 4 shown, before detection, the positions of the two semi-circular seats 214 are aligned with the position of the lead seal. If the position of the lead seal of the electricity meter changes, the knob can be rotated to drive the threaded rod 211 to rotate. After the threaded rod 211 rotates, it can drive the support rod 212 to slide. The top end of the support rod 212 slides in contact with the movable frame 210, which limits the movement of the support rod 212, so that the front and rear positions of the two support rods 212 can be adjusted, which facilitates subsequent detection and improves the practicability.

[0058] The adjusting component 3 is arranged on one side of the top of the movable plate 104;

[0059] The adjusting component 3 includes support blocks 301 symmetrically installed on one side of the top of the movable plate 104. An installation rod 302 is fixedly installed between the two support blocks 301. An activity sleeve 303 is slidably connected to the outer side of the installation rod 302.

A scale line is arranged on the movable plate 104 on the side of the pointer 304. A connecting frame 306 is fixedly installed outside the through groove 305 on one side of the activity sleeve 303. A positioning rod 307 is slidably connected inside the connecting frame 306. One end of the positioning rod 307 is fixedly installed with a positioning block 310. A plurality of rubber bumps are fixedly installed on the end of the positioning block 310 close to the installation rod 302;

[0060] A return spring 308 is sleeved on the outer side of the positioning rod 307. One end of the return spring 308 is fixedly connected to the connecting frame 306, and a connecting block 309 is fixedly installed at the other end of the return spring 308. At the same time, the connecting block 309 is fixedly connected to the positioning rod 307. Moreover, the return spring 308 is in a compressed state. One end of the positioning rod 307 away from the movable sleeve 303 is fixedly installed with a movable frame 311. A positioning sleeve 312 is slidably connected to the outer side of the movable frame 311. At the same time, the positioning sleeve 312 is fixedly connected to the movable sleeve 303. Moreover, a rotating rod 313 is rotatably connected to one side of the top of the movable sleeve 303 close to the movable frame 311. A cam 314 is fixedly installed on the outer part of the rotating rod 313. A push rod 315 is fixedly installed above the cam 314 on the outer part of the rotating rod 313.

[0061] Embodiment 3: As Figures 2-3 and Figures 8-9 shown, before detection, the push rod 315 can be rotated to drive the rotating rod 313 to rotate, so that the cam 314 rotates. After the cam 314 rotates, it can push the movable frame 311 to move. After the movable frame 311 moves, it can drive the positioning rod 307 to move. After the positioning rod 307 moves, it can compress the return spring 308 and make the positioning block 310 leave the mounting rod 302. Then, the movable sleeve 303 can be moved to adjust the position of the pointer 304. After adjustment, the rotating rod 313 is released. Under the action of the return spring 308, the positioning rod 307 and the positioning block 310 are reset, and the return spring 308 is in a compressed state. Through the reaction force, the positioning block 310 fits the mounting rod 302 to position the movable sleeve 303. According to the longest length of the lead seal connecting rope, the position of the pointer 304 on the movable plate 104 can be adjusted, so that the pointer 304 can move to the longest position of the specified length of the lead seal. The pointer 304 facilitates the staff to observe the moving displacement of the movable seat 204.

[0062] Working principle: When using this intelligent electricity meter lead seal detection device, first, according to Figures 1-9As shown, when detecting the length of the lead seal on the electricity meter, place the side of the electricity meter with the lead seal on the top, and convey the electricity meter through the conveyor belt 101. After the electricity meter moves, it fits against the baffle 109, and the two centering rods 110 can move the electricity meter to the middle of the baffle 109. Then stop the conveyor belt 101 from running, and start the electric push rod 103 to drive the movable plate 104 to move down. After the movable plate 104 moves down, one end of the L-shaped rod 229 fits against the electricity meter, aligning the lead seal on the electricity meter with the two semi-circular seats 214. Then make the movable plate 104 continue to descend. At this time, when the movable plate 104 descends and the L-shaped rod 229 and the movable rod 226 no longer move, the tension spring 228 can be deformed. Then, through the cooperation of the driving gear 225 and the toothed plate 227, the rotating shaft 222 is driven to rotate. Through the meshing of the first bevel gear 221 and the second bevel gear 223, the rotating gear 220 is driven to rotate. After the rotating gear 220 rotates, it drives the arc-shaped rod 215 to rotate through meshing with the toothed ring 218. During the rotation of the arc-shaped rod 215, the arc-shaped strip 216 slides inside the arc-shaped groove 217 to support the movement of the arc-shaped rod 215, enabling the arc-shaped rod 215 to retract into the semi-circular seat 214. Stop the descent of the movable plate 104 when the support rod 212 is about to contact the electricity meter. Then start the driving motor 203 to drive the bidirectional lead screw 202 to rotate, causing the two movable seats 204 to slide away from each other. One side of the movable seat 204 can fit and slide against the movable plate 104 for positioning, enabling the two semi-circular seats 214 to contact the connecting rope on the lead seal. The plumb bob can be located above the semi-circular seat 214. Then, as the movable seat 204 moves, one end of the L-shaped rod 229 can leave the top surface of the electricity meter. Then, under the action of the tension spring 228, the movable rod 226 is reset, and thus the arc-shaped rod 215 can be reset, enabling the plumb bob on the lead seal to be above the semi-circular seat 214 and the arc-shaped rod 215. As the two movable seats 204 move away, the connecting rope can be straightened, and the plumb bob can be above the semi-circular seat 214 and the arc-shaped rod 215 and will not easily fall off. If the movable seat 204 moves a certain distance but does not reach the specified length range, the movable block 207 slides on the fixed rod 206 and stretches the telescopic spring 208, and the reading of the tension sensor 209 changes. At this time, the length of the lead seal is too short and does not meet the requirements. If the movable block 207 moves when the movable seat 204 moves to the specified length range, the length of the lead seal meets the standard. At this time, the two movable seats 204 can be made to move away again, enabling the lead seal to be pulled, and the stability of the plumb bob installation on the lead seal can be detected. If the reading of the tension sensor 209 does not change after the movable seat 204 moves a distance exceeding the specified maximum distance, it proves that the length of the lead seal is too long. After the detection, make the two movable seats 204 move closer to raise the movable plate 104 so that the L-shaped rod 229 is above the electricity meter. Then make the movable rod 226 descend, enabling the arc-shaped rod 215 to retract, and the lead seal can be put down, which is more convenient for putting down the lead seal;

[0063] Before detection, the positions of the two semi-circular seats 214 are aligned with the seal position. If the seal position of the electricity meter changes, the knob can be rotated to drive the threaded rod 211 to rotate. After the threaded rod 211 rotates, it can drive the support rod 212 to slide. The top of the support rod 212 fits and slides with the movable frame 210, so as to limit the movement of the support rod 212, and the front and rear positions of the two support rods 212 can be adjusted, which is convenient for subsequent detection. Before detection, the push rod 315 can be rotated to drive the rotating rod 313 to rotate, so that the cam 314 rotates. After the cam 314 rotates, it can push the movable frame 311 to move. After the movable frame 311 moves, it can drive the positioning rod 307 to move. After the positioning rod 307 moves, it can compress the return spring 308, and make the positioning block 310 leave the mounting rod 302. Then the movable sleeve 303 can be moved to adjust the position of the pointer 304. After adjustment, the rotating rod 313 is released. Under the action of the return spring 308, the positioning rod 307 and the positioning block 310 are reset, and the return spring 308 is in a compressed state. Through the reaction force, the positioning block 310 fits the mounting rod 302 to position the movable sleeve 303. According to the longest length of the seal connecting rope, the position of the pointer 304 on the movable plate 104 can be adjusted, so that the pointer 304 can move to the longest position of the specified length of the seal, which is convenient for the staff to observe the moving displacement of the movable seat 204 through the pointer 304.
