Description

Technical Field

[0001] The present invention relates to the technical field of power detection, and specifically to an intelligent power meter replacement device without power interruption. Background Technique

[0002] An electric energy meter is an instrument used to measure electric energy, also known as a watt-hour meter, a kilowatt-hour meter, or a meter for measuring various electrical quantities. When using an electric energy meter, it should be noted that under low voltage (not exceeding 500 volts) and small current (tens of amperes), the electric energy meter can be directly connected to the circuit for measurement. Under high voltage or large current conditions, the electric energy meter cannot be directly connected to the line and needs to be used in conjunction with a voltage transformer or a current transformer. Low-voltage electric energy meters are divided into single-phase meters, three-phase four-wire direct-through meters, and three-phase four-wire meters with current transformers. The on-site situations of these metering devices are diverse, and the wiring is complex. In urban or county areas, residential metering devices are generally installed in corridors or shafts, commercial ones are usually in front of or behind storefronts, small power meters are generally in distribution rooms or on the outer walls of yards, and in rural areas, they are generally behind or on the side of houses, with some being high and some being low, currently generally around 2 meters to 2.5 meters, and there are also some on utility poles, with different situations. Generally, there are switches or knife switches before and after low-voltage single-phase meters and three-phase direct-through meters, and there is a terminal box in front of three-phase meters with current transformers. For this reason, a Chinese patent disclosed a device for facilitating the replacement of an electric energy meter, with the application number 202322370331.1. This patent solves the problem that when replacing an electric energy meter, installers need to have certain experience to prevent the electric energy meter from being loosely installed and damaged. When replacing the electric energy meter, it is necessary to repeatedly disassemble and fix screws, resulting in the replacement work of the electric energy meter being not only laborious and time-consuming but also inefficient.

[0003] However, during the use of the current meter replacement device, the power transmission lines of the electric energy meter need to be disassembled, resulting in the equipment connected to the electric energy meter needing to be powered off during the power meter replacement process. In some special occasions, continuous power supply needs to be ensured, and short-term power interruption will also affect the operation of the equipment, thereby reducing the convenience and safety of using the electric energy meter replacement.

[0029] 1. A convenient double-station label-changing mechanism is provided. The mutual cooperation between the components inside the convenient double-station label-changing mechanism optimizes the meter replacement process of the meter replacement device. The double-station structural design of the meter replacement slot makes the operation process of the new and old meters clearer and more convenient to watch. The bypass power supply system composed of the connection cable tray, the transmission line and the connector makes it possible to replace the meter without power outage, thereby ensuring the continuity of power supply. At the same time, the built-in meter inside the central replacement box monitors and records the power data during the meter replacement process in real time, thereby ensuring that the power is not cut off during the meter replacement process. After the meter replacement is completed, the data cable connected to the data wiring hole synchronizes the power used in the meter replacement process to the new meter, ensuring that no power is lost during the meter replacement process, and no power is involved in the refund of power, thereby preventing different users from having ambiguities and disputes over power and electricity charges, and improving the smoothness of the use of the meter replacement device;

At the same time, the clamping of the clamping narrow strip and the guide small plate ensures that the position of the cable will not change during the meter replacement process, thereby ensuring the accuracy of the wiring during the meter replacement process, improving the efficiency and safety of the entire meter replacement process, and further improving the use fluency and use effect of the meter replacement device;

[0031] In addition, through the cooperation between the positioning airbag and the active airbag, the old and new meters can be quickly clamped and positioned, so that the meter can be quickly clamped by the positioning airbag during the process of replacing the wiring. When the meter needs to be taken out from the meter replacement slot, the active airbag can be toggled to expand the center toggle piece to quickly push the old and new meters out of the meter replacement slot, thereby effectively improving the efficiency and stability of the fixation during the meter replacement process. At the same time, through the alternating expansion of the inner airbag and the telescopic round bag, the connecting wire reel can be extended and stored according to the use status of the meter changing device, ensuring that the meter changing device can be extended together with the coiled power transmission line during use, and the power transmission line can be orderly stored when the meter changing device is idle, further improving the safety and convenience of the meter changing device.

[0032] 2. A tail multi-angle installation mechanism is provided. Through the cooperation between the components inside the tail multi-angle installation mechanism, the installation and fixing process of the meter changing device is optimized. The installation back box is quickly supported by the supporting square tube and the components connected thereto. Through the cooperation between the locking bolt and the air guide valve, the length and position of the supporting square tube, the telescopic middle tube and the telescopic inner tube can be quickly adjusted to meet the installation requirements of different heights, ensuring that the meter changing device can be stably supported in different environments.

[0033] At the same time, through the cooperation between the horizontal electromagnet and the vertical electromagnet, the meter changing device can be quickly adsorbed to the side of the meter box or other metal shell to achieve the adsorption and fixation of the meter changing device, and through the cooperation between the swinging horizontal plate and the clamping horizontal plate, the meter changing device can be flexibly clamped to the side gap of the meter box or the wall to achieve multi-scene fixation of the meter changing device, and the tools needed in the meter changing process can be stored through the storage vertical box, which further expands the function of the meter changing device and makes the installation of the meter changing device faster and more convenient.

[0034] In summary, the installation process of the meter changing device and the meter replacement process are optimized through the mutual cooperation between the components inside the convenient double-station label changing mechanism and the tail multi-angle installation mechanism. Through the linkage structure design of the components inside the supporting square tube, the magnetic adsorption of the horizontal electromagnet and the vertical electromagnet, and the snap-on installation design of the snap-on horizontal piece and the storage vertical box, the meter changing device can be quickly fixed and installed according to the use environment during use, thereby effectively improving the installation convenience of the meter changing device. In addition, through the double-station design of the meter changing slot and the linkage structure design of the components therein, the installation and disassembly process of the old and new meters during the meter replacement process is more convenient, and the wiring process of the cable at the bottom of the meter is quickly replaced, thereby ensuring that the power supply to the electrical equipment can be maintained during the meter replacement process, further improving the convenience and stability of the meter replacement equipment.

[0064] And through the cooperation between the positioning airbag 324 and the active airbag 327, the new and old electric meters are quickly clamped and positioned, so that the electric meter can be quickly clamped by the positioning airbag 324 during the process of replacing the wiring, and when the electric meter needs to be taken out from the inside of the meter replacement slot 301, the active airbag 327 can be expanded upward by toggling the central toggle piece 321 to quickly push the new and old electric meters out of the inside of the meter replacement slot 301, thereby effectively improving the efficiency and stability of the fixation during the replacement of the electric meter. At the same time, through the alternating expansion between the connecting inner airbag 328 and the telescopic round bag 331, the connecting wire reel 336 can be extended and stored according to the use status of the meter replacement device, ensuring that the meter replacement device can be extended together with the coiled power line 337 during use, and the power line 337 can be orderly stored when the meter replacement device is idle, further improving the safety and convenience of the use of the meter replacement device;

[0065] A rear multi-angle mounting mechanism 4 is provided on the back of the mounting back box 2. The rear multi-angle mounting mechanism 4 is used to optimize the fixing process of the meter changing device so as to support and limit the meter changing device in different environments.

[0072] At the same time, through the mutual cooperation between the horizontal electromagnet 413 and the vertical electromagnet 414, the meter changing device can be quickly adsorbed to the side of the meter box or other metal shell to achieve the adsorption and fixation of the meter changing device, and through the mutual cooperation between the swinging horizontal plate 416 and the snap-on horizontal piece 417, the meter changing device can be flexibly snapped into the side gap of the meter box or the wall to achieve multi-scene fixation of the meter changing device, and the storage vertical box 418 can be used to store the tools needed in the meter changing process, further expanding the function of the meter changing device and making the meter changing device install more quickly.

[0073] Working principle and use process of the present invention: In actual application, when using the meter replacement device to replace the old meter with the new one, after placing the central replacement box 1 and the installation back box 2 in the appropriate position, the old meter is removed from the original position, and then the old meter and the new meter are placed in the two meter replacement slots 301 respectively, and the cables connected to the old meter are aligned with the wire slots 304. In the process of connecting the old and new meters to the meter replacement slots 301, the meter will simultaneously squeeze the active airbag 327 and the connecting inner airbag 328. When the active airbag 327 is squeezed, the airbag 328 will be connected to the new meter through the air guide inner The tube 326 guides the airflow into the transmission airbag 325, and the compressed airflow enters the transmission airbag 325, so that the transmission airbag 325 expands and pushes the central toggle piece 321 to slide along the inner installation rectangular box 320, and in the process of the central toggle piece 321 sliding, the pressing airbag 322 is squeezed, and then the gas in the pressing airbag 322 can flow into the positioning airbag 324 through the pressing air guide tube 323, so that the positioning airbag 324 expands toward the inside of the meter replacement slot 301, and in the process of the meter replacement slot 301 expanding, the end of the meter is squeezed and limited, thereby completing the positioning installation of the new and old meters;

[0074] When the active airbag 327 is squeezed, the connecting inner airbag 328 is also squeezed at the same time. After the connecting inner airbag 328 is compressed, the airflow is introduced into the inside of the air guide round box 330 through the air guide central tube 329, and the telescopic round bag 331 is expanded after the air pressure inside the air guide round box 330 rises. The expansion of the air guide round box 330 drives the telescopic slide 332 to slide along the length direction of the guide narrow groove 333, and in the process of the sliding of the telescopic slide 332, the guide narrow groove 333 is gradually connected with the connecting volute spring 335. The ends are separated from each other, and the connecting wire tray 336 and the components thereon are pushed out from the side of the central replacement box 1 by sliding the telescopic slide 332, and one end of the transmission line 337 is connected to the connecting wire tray 336 through a plug, and the type of the connector 338 is replaced according to the on-site environment, and then the two connectors 338 are connected to the main switch power output end and the user switch power input end to complete the power connection at both ends of the central replacement box 1, and the built-in electric meter inside the central replacement box 1 is used to record the power consumption;

[0075] After the guide plate 306 and the support strip 312 are engaged with each other, the cable at the bottom of the old meter is clamped and fixed by the guide plate 310;

[0076] Then, the fixing screws at the bottom of the old meter are loosened by using a corresponding screwdriver so that the cables at the bottom of the old meter can be removed from the old meter. Then, the limiting outer narrow plate 317 is moved in the vertical direction. During the sliding of the limiting outer narrow plate 317, the connecting cylinder 315 and the pressing narrow strip 316 are simultaneously driven to slide along the inside of the oblong guide groove 311. During the sliding of the pressing narrow strip 316, the cables are pulled out from the bottom of the old meter to complete the removal of the cables of the old meter.

[0077] After the cable is pulled out from the bottom of the old meter, the replacement personnel manually push the guide slide plate 305 to slide horizontally, and the sliding of the guide slide plate 305 drives the removed cable connector to slide synchronously. When the cable connector is aligned with the connection port of the new meter, the limiting outer narrow plate 317 is manually pushed upwards, and the cable is inserted into the port at the bottom of the new meter by moving the limiting outer narrow plate 317. Then, the fixing screws at the bottom of the new meter are tightened with a screwdriver to ensure that the cable is firmly connected, and the line connection between the new and old meters is completed. The guide slide plate 305 is slid back to the starting position to ensure that all components are back to the standby state. At this time, the data in the built-in meter of the central replacement box 1 can be synchronized to the new meter through the control side screen 302 to complete the wiring replacement and data synchronization of the new and old meters.

[0078] When it is necessary to take out the replaced old and new meters from the meter replacement slot 301 and install the new meter to a suitable position, the replacement personnel reversely toggle the central toggle piece 321 to compress the pressing airbag 322 and the transmission airbag 325 at the same time, thereby causing the positioning airbag 324 to shrink and the active airbag 327 to expand, and the new and old meters are pushed out from the meter replacement slot 301 by the expansion of the active airbag 327, and then the new and old meters are manually taken out and the new meter is installed to a designated position, ensuring that all components are reset to complete the replacement of the new meter;

[0079] Meanwhile, after the electricity meter is taken out from the inside of the meter replacement slot 301, the airflow inside the telescopic round bladder 331 will flow back into the inside of the connecting inner bladder 328, causing the telescopic round bladder 331 to contract and drive the telescopic sliding cylinder 332 and each component thereon to reset, so as to ensure that the removed power transmission line 337 is wound around the outside of the connecting wire reel 336 for storage, thus completing the replacement process of the entire electricity meter;

[0080] Before using the meter replacement device to replace the electricity meter, the meter replacement device needs to be installed near the electricity meter first. During the installation process of the meter replacement device, the installation method can be adjusted according to the on-site environment. When it is necessary to directly support the meter replacement device against the wall, after loosening the locking bolt 407 and pulling out the support rubber block 406 from the inside of the installation back groove 401, directly open the air guide valve 412 so that the external air can enter the air guide hose 409 through the inflatable round box 411, and transmit the air to the connecting round tube 408 through the air guide hose 409, so that the support square tube 403, the telescopic middle tube 404, and the telescopic inner tube 405 can extend in sequence under the action of gravity. When the bottom surface of the support rubber block 406 contacts the ground and is stable, re-lock the locking bolt 407 and close the air guide valve 412 at the same time to complete the support and fixation of the bottom components of the installation back box 2;

[0081] When it is necessary to adsorb the meter replacement device to the outside of the electricity meter box, it is necessary to first pull down the connecting round tube 408 and each component thereon to the bottommost position of the installation back box 2 through the cooperation between the locking bolt 407 and the support square tube 403, and then attach the horizontal electromagnet 413 and the vertical electromagnet 414 to the corresponding positions on the outside of the electricity meter box. Activate the horizontal electromagnet 413 and the vertical electromagnet 414 by controlling the top button 415, and then firmly adsorb the meter replacement device to the outside of the electricity meter box through the magnetic force of the horizontal electromagnet 413 and the vertical electromagnet 414;

[0082] When it is necessary to clamp the meter replacement device into the gap between the electricity meter box or the wall side, flip the swing cross plate 416 to the horizontal position, and then rotate out the clamping cross piece 417 and insert it into the gap inside the electricity meter box or the wall side to complete the clamping and fixation of the meter replacement device;

[0083] At the same time, the storage vertical box 418 can be used to store the tools required during the meter replacement process in an orderly manner, ensuring that the staff can quickly access the required tools during the meter replacement process, and using the support film 419 to assist in supporting the bottom of the central replacement box 1 and the installation back box 2 to ensure that the meter replacement device can be stably placed during use.

[0084] Finally, it should be noted that the above are only preferred examples of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features.
