Description

Technical Field

[0001] This invention belongs to the field of smart grid monitoring technology, specifically a smart grid monitoring and control box. Background Technology

[0002] The smart grid monitoring and control box is an intelligent power distribution terminal device that integrates data acquisition, status monitoring, remote control, and communication transmission functions. It is mainly deployed at the end of the power distribution network, such as in industrial areas. It has high requirements for power grid on / off and is the core hardware carrier for realizing intelligent and refined management of the power grid. Its structure consists of a hardware layer and a software layer: the hardware layer includes the box structure unit, data acquisition units such as sensors and transformers, control execution units such as circuit breakers and relays, communication transmission units such as communication modules and backup batteries, and core processing units such as embedded controllers.

[0003] However, due to the large number of electrical appliances installed in the meter box, workers may neglect to make loose connections during installation. Loose connections increase contact resistance, causing local voltage drops and current waveform distortion. This leads to deviations in the collected electrical parameters such as voltage, current, and power, and may even generate false data. For example, a loose connection at the three-phase input terminal can cause excessive three-phase current imbalance, which the meter box may mistakenly interpret as an abnormal load. Furthermore, the local temperature rise caused by loose connections can interfere with the normal monitoring of temperature sensors, masking the true ambient temperature of the meter box. It may also falsely trigger over-temperature alarms or cause the heat dissipation and dehumidification module to malfunction due to inaccurate temperature data. Moreover, the arc discharge and high temperature at the loose connection can burn the wiring terminals of sensors and transformers, causing a decrease in sensor sensitivity or even complete damage, directly resulting in the loss of the corresponding monitoring function.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: To effectively solve the above problems, see the attached diagram in the instruction manual. Figure 1-6 As shown, a smart grid monitoring and control box includes a box body 1, a data acquisition unit, an execution unit, a communication unit, and a processing unit; it also includes: Mounting bracket 11 is fixed to the inner wall of the housing 1. Electrical appliances in the control box are mounted on the mounting bracket 11. A detection block 12 is slidably connected to the mounting bracket 11. A wire clamp 13 is provided inside the detection block 12. A sensing sensor is provided on the wire clamp 13. A squeezing block 14 is provided on one side of the wire clamp 13. A cleaning airbag 15 is provided between the squeezing block 14 and the detection block 12. The air nozzle of the cleaning airbag 15 faces the terminals on the electrical appliance. An electric vertical rod 16 is vertically installed inside the housing 1. An electric horizontal rod 17 is mounted on the electric vertical rod 16, and a test box 18 is mounted on the electric horizontal rod 17. The electric vertical rod 16 and the electric horizontal rod 17 work together to drive the test box 18 to move up, down, and sideways. The test box 18 contains a testing electrical appliance, and a pressure block 19 is provided on one side, which contacts the squeezing block 14. A rotating rod 2 is slidably connected below the pressure block 19. The rotating rod 2 is connected to the test box 18 through an electric push rod 21. A rotating motor 22 is provided between the extension and retraction ends of the rotating rod 2 and the electric push rod 21. The end of the rotating rod 2 has a connector for rotating the screws on the electrical appliance terminals. A detection rod 23 is provided on one side of the rotating rod 2, and the detection rod 23 is connected to the testing electrical appliance. The detection block 12 slides on the mounting bracket 11. When fixation is required, it can be completed by simply tightening the bolts. The wire clamp 13 is a U-shaped wire clamp commonly used in the meter box for fixing wire harnesses. The wire harness is inserted into the wire clamp 13 through the opening of the U-shape, and the wire clamp 13 holds and fixes the wire harness by its own elastic contraction property. The sensing sensors installed on the wire clamp 13 include temperature sensors, Hall current sensors, etc. The Hall current sensor is based on the Hall effect and realizes the function of isolation measurement by detecting the magnetic field generated by the current, thus completing the measurement of the current in the wire harness. The air nozzle of the cleaning airbag 15 faces the terminal on the electrical appliance, and the air intake is away from the electrical appliance. The electric vertical bar 16 and the electric horizontal bar 17 are conventional electric drives. The linear sliding device uses an electric vertical rod 16 to raise and lower an electric horizontal rod 17, which in turn moves the test box 18 horizontally. Workers can hold the test box 18 and move it electrically during wiring, reducing the time spent holding it and improving installation efficiency. The test electrical appliances are standard for testing loose connections and appliance quality. The rotating motor 22 on the rotating rod 2 is used to rotate the rotating rod 2 with a set torque to tighten the terminal screws. Various types of torque motors are included to prevent excessive or insufficient torque from affecting wiring quality. The connector on the rotating rod 2 is a Phillips screwdriver or similar tool. The probe rod 23 is used to detect the wiring quality of electrical appliances under power-off conditions. The electrical wiring connection includes terminals and screws.

[0022] Specific workflow: When wiring the meter box, the worker slides the detection block 12 to some important electrical terminals and fixes it with bolts. The detection block 12 is not used for unimportant electrical terminals. Then, the wire harness is inserted and fixed through the U-shaped opening on the wire clamp 13. The worker drives or controls the test box 18 to pass through the detection block 12. The test box 18 drives the pressure block 19 to pass through the squeezing block 14. The inclined surface of the pressure block 19 contacts and presses the squeezing block 14. The squeezing block 14 extends into the detection block 12 and squeezes the cleaning airbag 15. The cleaning airbag 15 sprays air onto the wire harness interface and electrical terminals to blow away the dust on the surface, so as to avoid the dust attached to affect the wiring quality, ensure the accuracy of monitoring data, improve the stability of line connection and monitoring, and thus improve the reliability of intelligent monitoring. Next, the worker inserts the wire harness interface into the terminal. The worker then uses the combined action of the electric vertical rod 16 and the electric horizontal rod 17 to move the test box 18. The test box 18 moves the rotating rod 2 to align with the terminal screw. The electric push rod 21 is activated, causing the end of the rotating rod 2 to engage with the terminal screw. Then, the rotating motor 22 is activated, causing the rotating rod 2 to rotate at a set torque. The rotating rod 2 tightens the terminal screw to secure the wire harness with a set torque. Insufficient screw torque results in insufficient contact pressure between the wire and the terminal, leading to increased contact resistance. Excessive screw torque can cause terminal deformation, screw stripping, or breakage, resulting in a reduced wire cross-sectional area and decreased current carrying capacity, which can also cause overheating. This improves the quality of electrical wiring and, consequently, the reliability of intelligent monitoring. Furthermore, after the meter box is installed, the internal screws and other fasteners may loosen due to vibration and temperature changes. Without opening the box door, workers can use the electric vertical rod 16 and electric horizontal rod 17 to control the movement of the rotating rod 2 to perform a torque retest one by one, focusing on high-current parts such as the incoming terminals and circuit breaker terminals. The test results are displayed on the meter box screen through the test electrical circuit, preventing screws from loosening due to vibration and temperature changes and improving the stability of the wiring connection. Moreover, the above method can also reduce the number of times the box door is opened, avoiding the large amount of dust from the outside industrial area entering the meter box each time the box door is opened, which may affect the conductivity of electrical appliances and wiring harnesses. During the operation of electrical appliances, if the sensing sensor reports an abnormality, the worker can move the probe rod 23 through the test box 18 to align it with the terminal, and then use the electric push rod 21 to move the probe rod 23 to contact the terminal to directly detect the power supply and heating of the terminal. Combined with the monitoring results of the sensing sensor on the wire clamp 13, the worker can troubleshoot the abnormality or perform maintenance operations, thus improving the ease of use. Furthermore, when the test box 18 is re-inspecting each appliance, the probe rod 23 can detect appliances other than the detection block 12, covering all appliances in the meter box, expanding the detection range, and ensuring the stability of the meter box operation.

[0023] Example 2: Based on Embodiment 1, the probe rod 23 is slidably connected to the side wall of the test box 18. The probe rod 23 is provided with a probe head 24, which is located near the rotating rod 2. One end of the rotating rod 2 is provided with a cleaning ring 25, and a cleaning brush 26 is provided on the cleaning ring 25. The outer side of the cleaning brush 26 contacts the probe head 24. A top block 27 is slidably connected to the probe rod 23 by a spring. The probe rod 23 is hollow inside and is provided with a compression airbag 28. One end of the top block 27 extends into the probe rod 23 and covers one side of the compression airbag 28. The air outlet of the compression airbag 28 faces the electrical terminal. The rotating rod 2 is provided with protrusions 29 evenly, and the protrusions 29 are in contact with the ball bearings provided at one end of the top block 27. A portion of the surface of the cleaning ring 25 is not provided with a cleaning brush 26. The cleaning ring 25 is provided with spring pieces 3 evenly on the side away from the test box 18. The spring pieces 3 are arc-shaped and some cleaning brushes 26 are distributed on the spring pieces 3. The cleaning brushes 26 on the spring pieces 3 contact the electrical terminals. A polishing box 31 is slidably connected to one side of the test box 18, and the polishing box 31 is close to the upper and lower parts of the electrical appliance. The polishing box 31 is connected to the electric telescopic rod 32 in the test box 18. A cutter 33 is slidably connected to the detection block 12 via a spring. The cutter 33 is made of ceramic and has the function of cutting wire harnesses and providing insulation. The grinding box 31 has a protrusion 34 that contacts the cutter 33.

[0024] Specific workflow: During testing, the probe rod 23 detects through the probe head 24. When the rotating rod 2 contacts the terminal, the probe head 24 also contacts the terminal. During testing, the rotating rod 2 provides mechanical support and positioning for the terminal, while the probe head 24 synchronously contacts the terminal and applies stable pressure. The connection status is verified in two ways: First, through the torque feedback of the rotating rod 2, it is determined whether the terminal screw is loose. If the rotating rod 2 can move the terminal with a slight rotation, it indicates that the screw torque is insufficient. Second, the pressure sensor or displacement sensor built into the probe head 24 can detect the degree of deformation of the terminal after being subjected to pressure. If the deformation exceeds the threshold, it indicates that the terminal has poor contact due to oxidation, deformation, etc. This is for outdoor meter boxes caused by vibration and temperature changes. To address the issue of loose terminals, this operation replaces the subjective defects of manual visual inspection, enabling quantitative detection, improving the accuracy of daily maintenance inspections, ensuring the stability of the meter box operation, and thus improving the reliability of intelligent monitoring. Furthermore, the probe rod 23 is made of insulating material, isolating the live parts of the terminal from the inspector. The rotating rod 2 uses a small-area contact method, rather than the traditional clamping contact, which avoids terminal short circuits or wire detachment due to improper operation. Simultaneously, the contact area of ​​the probe head 24 precisely matches the terminal size, preventing localized arcing caused by an insufficient contact area, avoiding the risk of electric shock to inspectors, and not damaging the original wiring of the terminal, thus eliminating secondary faults caused by the inspection operation. Before the probe 24 is tested, its surface may be contaminated with dust and other impurities due to long-term static storage. Direct testing may cause electrical sparks or short circuits. Therefore, the rotating rod 2 drives the cleaning ring 25 to rotate, while the probe 23 is slidably connected to the side wall of the test box 18 and is used to extend and retract with the rotating rod 2, but cannot rotate with the rotating rod 2. This allows the rotating rod 2 to rotate while the probe 23 remains fixed. The rotating rod 2 drives the cleaning brush 26 to rotate through the cleaning ring 25. The cleaning brush 26 gently sweeps the probe 24 to remove impurities, improve the cleanliness of the test process, and ensure the stability of the test data. The rotating rod 2 also drives the protrusion 29 to rotate. The rotation of the protrusion 29 repeatedly squeezes the top block 27. The top block 27 squeezes out the air in the squeezing airbag 28. The air in the squeezing airbag 28 is sprayed towards the probe 24 during the cleaning process. With the action of the sweeping brush, impurities are blown away from the probe 24 and electrical components, and discharged through the heat dissipation holes of the housing 1, improving cleanliness and thus ensuring the data stability of the detection process. After the top block 27 passes the squeezing airbag 28, it no longer squeezes. The squeezing airbag 28, through its elastic recovery, draws clean air away from the probe 24, preparing for the next blowing cleaning. Furthermore, the protrusion 29 and the top block 27 achieve rolling contact through ball bearings, reducing friction generated during contact and preventing excessive wear debris from adhering to the surface of electrical wiring harnesses, thereby improving the stability of the meter box operation. In addition, workers can choose to use an insulated cleaning brush 26 and extend its length. Before wiring electrical appliances or before testing, the rotating rod 2 drives the cleaning brush 26 to contact the terminals and other testing parts. The cleaning brush 26 rotates to sweep away impurities on the terminals, avoiding the influence of dust during the testing process, thereby improving the accuracy of the test data and the reliability of intelligent monitoring. In addition, when the cleaning brush 26 removes impurities from the terminals, the rotating rod 2 does not contact the terminals, and the rotation of the rotating rod 2 does not affect the operation of the terminals. The squeezing airbag 28 keeps blowing air frequently to blow away the impurities on the terminals, improving the cleanliness of the detection head 24 and the detection area, improving the accuracy of the detection data, and thus improving the reliability of intelligent monitoring. When the detection head 24 is about to contact the detection, the cleaning ring 25 rotates the cleaning brush 26 to a position away from the detection head 24, that is, the cleaning brush 26 does not contact the detection head 24, thus avoiding the cleaning brush 26 affecting the detection of the detection head 24. During wiring, the cleaning ring 25 presses the cleaning brush 26 onto the terminal, increasing the contact force between the cleaning brush 26 and the terminal surface and improving cleaning ability. The cleaning ring 25 also drives the spring 3 to contact the terminal, while the rotating rod 2 is located on one side of the terminal and does not contact the terminal. This allows the rotating rod 2 to drive the spring 3 to rotate through the cleaning ring 25, providing support for the cleaning brush 26. While improving the cleaning effect, the spring 3 also gently scrapes the terminal surface to remove any oxide layer that may have formed on the terminal surface, improving the cleanliness of the terminal surface. This prevents the oxide layer on the terminal surface from affecting the test results during testing, thereby improving the accuracy of the test data and the reliability of intelligent monitoring. Furthermore, by setting up grinding boxes 31, with two grinding boxes 31 at the top and bottom of the test box 18 forming a closed cover with the test box 18, during wiring, the grinding boxes 31 are moved away from the electrical appliance by the electric telescopic rod 32 and placed on the side of the test box 18 away from the electrical appliance, exposing the wiring part, which facilitates worker operation, improves the quality of electrical appliance wiring, and thus improves the reliability of intelligent monitoring; during periodic testing or troubleshooting, the electric telescopic rod 32 drives the grinding boxes 31 to extend closer to the electrical appliance, covering the electrical appliance and the connected wiring harness, reducing other interference, and improving... For example, if the meter box shows abnormal monitoring, such as voltage fluctuations or temperature rise alarms, the inner wall of the grinding box 31 can be made of metal plating or conductive plastic material to form a simple electromagnetic shielding space. During fault diagnosis, the grinding box 31 can isolate the electromagnetic radiation of other components in the meter box after being closed, avoid the reading of the probe 24, and minimize the measurement error of key parameters such as terminal contact resistance and voltage drop. This helps workers quickly distinguish between terminal loose connections and sensor malfunctions, improves fault location efficiency, and reduces the danger of manual inspection by workers. If an electrical appliance malfunctions or encounters a dangerous situation, the test box 18 will cause the grinding box 31 to cover the appliance, preventing the danger from escalating and affecting surrounding appliances. Then, the electric telescopic rod 32 will cause the grinding box 31 to extend further on top of its extended length. The protrusion 34 of the grinding box 31 will contact and drive the cutter 33 to move. The cutter 33 will move towards the wiring harness and cut off the wiring harness connected to the appliance, thus cutting off the power supply harness in time. In the event of an emergency power outage, the appliance will be restored to its original state as much as possible, facilitating subsequent troubleshooting by workers and improving the reliability of monitoring. Furthermore, after the power supply harness on the detection block 12 is cut, it is still held and fixed by the wire clamp 13, and the cut end of the harness is fixed and wrapped by the surface of the cutter 33, preventing the live wire harness from being exposed, thereby improving the safety level. Moreover, when workers are troubleshooting problems, they only need to disconnect the power and then use the electric telescopic rod 32 to drive the grinding box 31 to reset for subsequent operations, and the test box 18 and other components remain intact, improving the ease of use.

[0025] Example 3: Based on Embodiment 2, a rotating shaft 35 is rotatably connected inside the grinding box 31. The rotating shaft 35 is connected to the rotating rod 2. A linkage rod 36 is rotatably connected near the end of the grinding box 31. A grinding brush 37 is provided at the bottom of the linkage rod 36 and faces the electrical terminal. A spring is provided between the linkage rod 36 and the grinding box 31. A linkage block 38 is slidably connected inside the grinding box 31 through the spring. The inclined surface of the linkage block 38 contacts the top of the linkage rod 36. The linkage rod 36 and the rotating shaft 35 are perpendicular to each other and connected by a bevel gear. For example, a bevel gear is sleeved on the linkage rod 36 and a bevel gear is sleeved on the rotating shaft 35. When the linkage rod 36 is descending, the two bevel gears are not in contact. After the linkage rod 36 drives the bevel gears to descend, the two bevel gears are connected and drive each other. Alternatively, the bevel gears can be replaced with a cone-shaped body, and transmission can be achieved through frictional contact. Alternatively, the worker can replace the rotating shaft 35 and the bevel gears with a conventional motor or electric motor, and add additional control circuitry to control the linkage rod 36 to rotate. The linkage rod 36 is evenly provided with hooks 39 at its bottom and middle; The hook 39 in the middle of the linkage rod 36 extends out of the polishing brush 37, and the end of the hook 39 in the middle of the linkage rod 36 is provided with barbs.

[0026] Specific workflow: Rotating rod 2 is connected to rotating shaft 35 in a conventional manner, such as tooth and groove contact. Rotating rod 2 drives rotating shaft 35 to rotate. When grinding box 31 retracts, linkage block 38 is stationary at the top, and linkage rod 36 is not connected to rotating shaft 35. During wiring, grinding box 31 extends to the wiring point near the terminal. Grinding box 31 drives linkage block 38 to contact the inner wall of detection block 12, causing linkage block 38 to be pressed into grinding box 31. The inclined surface of linkage block 38 presses against the top of linkage rod 36 and causes it to descend. The descent of linkage rod 36 causes the two bevel gears to... Upon contact, the rotating shaft 35 drives the linkage rod 36 to rotate, and the linkage rod 36 drives the polishing brush 37 to descend to the terminal wiring position and then rotate. The polishing brush 37 polishes the metal parts at the wiring position, removing the oxide layer and impurities on its surface. In conjunction with the rotation of the rotating rod 2, the air-pressing bag 28 blows air to remove all impurities inside and outside the terminal, improving the cleanliness of the terminal, thereby improving the wiring quality of the electrical appliance and thus improving the reliability of intelligent monitoring. When the polishing box 31 moves away from the electrical appliance, the linkage rod 36 rises to reset, and the linkage block 38 extends to reset. By setting a hook 39, which is located inside the polishing brush 37, a stable support force is provided for the polishing brush 37, improving the polishing and removal effect of the polishing brush 37 on the oxide layer, thereby improving the cleanliness of the terminal. Furthermore, since the hook 39 in the middle of the linkage rod 36 extends out of the polishing brush 37, in the event of an emergency, after the polishing box 31 drives the cutter 33 to cut the power supply harness, the linkage rod 36 contacts the remaining part of the power supply harness in a rotating state. The linkage rod 36 drives the hook 39 to rotate, and the hook 39 uses barbs to tie the remaining harness and wrap it around the linkage rod 36 as it rotates. On the one hand, this fixes the cut harness on the electrical appliance, preventing some electrical appliances from briefly discharging through the harness. If these harnesses are not fixed, they may come into contact with other electrical appliances or the housing 1 and discharge, causing a dangerous situation. Moreover, the lower part of the linkage rod 36 can be made of a tough material such as hard rubber to prevent the linkage rod 36 from making too hard contact with the terminal surface, which could damage the terminal.

[0027] Example 4: Based on Embodiment 3, the inner wall of the box 1 is provided with a mounting block 4, the electric vertical rod 16 is fixed to the mounting block 4 by screws, and the test box 18 is connected to the control system of the box 1. The test box 18 is provided with a camera component 41 on one side, and the camera component 41 is located below the pressure block 19.

[0028] Specific workflow: By setting up mounting block 4, the electric vertical rod 16 is fixed to mounting block 4 with screws during wiring. The test box 18 can be used by workers through simple operation. After the wiring is completed, when the test box 18 is no longer needed, the screws between the electric vertical rod 16 and mounting block 4 can be removed to take it away. This makes the test box 18 and other components easy to disassemble and assemble, improving the ease of use. Even during testing or maintenance, the test box 18 can be used through simple installation. By setting up the camera component 41, workers can observe the terminal and wiring quality at close range during inspection or wiring, eliminate loose connections in advance, thereby improving the wiring quality of electrical appliances and thus improving the reliability of intelligent monitoring.
