Description

Technical Field

[0001] This utility model belongs to the technical field of electricity metering boxes, specifically relating to an electricity metering box with real-time early warning function. Background Technology

[0002] In the operation of the power system, the electricity metering box, as a key device for measuring electricity consumption, is an important link between the power supplier and the power consumer. Its metering data is not only the core basis for electricity bill settlement, but also the basic support for power dispatching, load forecasting and power grid planning. Therefore, the stable operation and safety protection of the electricity metering box are of paramount importance.

[0003] Currently, to ensure the safe operation of electricity metering boxes, most existing electricity metering boxes adopt locks or mechanical latches for their opening and closing mechanisms. However, this opening and closing mechanism has certain defects, namely, the lack of a linkage mechanism with the monitoring system, making it impossible to monitor and record the opening and closing status of the box door in real time. When criminals steal electricity or tamper with metering data by damaging the locks, prying the latches, or forcibly opening the box door, not only will inaccurate metering lead to the loss of electricity fees, but improper wiring may also cause safety hazards such as short circuits and leakage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an energy metering box with real-time early warning function, comprising a box body, wherein the box body is provided with an energy metering module, a real-time monitoring module, an early warning communication module, an alarm, and an early warning opening and closing component; The power metering module installed inside the box is electrically connected to the real-time monitoring module, the real-time monitoring module is electrically connected to the early warning communication module, and the early warning communication module is electrically connected to the early warning opening and closing component. The warning opening and closing assembly includes a rotating shaft and a limiting tooth block. A gear block is configured at one end of the rotating shaft. A pressure sensor is installed between two teeth of the limiting tooth block. The pressure sensor is in contact with two teeth of the gear block. The pressure sensor is electrically connected to the integrated early warning and communication module.

[0006] In a preferred embodiment, a guide post extends integrally from one side of the limiting tooth block, and one end of the guide post is provided with a plug-in portion, which is equipped with a locking pin.

[0007] In a preferred embodiment, the warning opening and closing assembly further includes a fixing plate, one end of which is provided with a protrusion and a screw cavity. The insertion part of one end of the guide post passes through the fixing plate and is connected to the screw cavity of the protrusion with a locking pin.

[0008] In a preferred embodiment, the warning opening and closing assembly further includes a guide cylinder, which is fixed to the bottom of the housing, and the guide post is connected through the guide cylinder.

[0009] In a preferred embodiment, a retaining ring is provided on one side of the guide post, and a return spring is provided on one side of the retaining ring, the return spring being connected to one side of the fixing plate.

[0010] In a preferred embodiment, the housing is equipped with a movable plate, which is connected to a rotating shaft. A positioning block is provided on one side of the movable plate, and the positioning block is equipped with a fixing pin.

[0011] In a preferred embodiment, the bottom of the housing is provided with a hidden frame, and the warning opening and closing component is located in the hidden frame.

[0017] The present invention will be further described below with reference to the embodiments.

[0018] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0019] Please see Figures 1-6 This utility model provides an energy metering box with real-time early warning function, including a box body 1. The box body 1 is equipped with an energy metering module 3, a real-time monitoring module 31, an early warning communication integrated module 4, an alarm 5, and an early warning opening and closing component 6. The energy metering module 3 and the real-time monitoring module 31 are electrically connected to each other. The real-time monitoring module 31 is electrically connected to the early warning communication integrated module 4. The early warning communication integrated module 4 is electrically connected to the early warning opening and closing component 6. The early warning opening and closing component 6 includes a rotating shaft 61 and a limiting gear block 62. One end of the rotating shaft 61 is equipped with a gear block 611, and the limiting gear block 62... A pressure sensor 63 is installed between the two teeth of the gear block 611. The pressure sensor 63 is in contact with the two teeth of the gear block 611. The pressure sensor 63 is connected to the early warning communication integrated module 4 via a ribbon cable. A guide post 621 extends integrally from one side of the limit tooth block 62. One end of the guide post 621 is provided with a plug part 622. The plug part 622 is equipped with a locking pin 623. The early warning opening and closing assembly 6 also includes a fixing plate 64. One end of the fixing plate 64 is provided with a protrusion. The protrusion is provided with a screw cavity. The plug part 622 at one end of the guide post 621 passes through the fixing plate 64 and is connected to the screw cavity of the protrusion in cooperation with the locking pin 623.

[0020] In this embodiment, a monitoring and early warning system is constructed through the electrical connection of the power metering module 3, real-time monitoring module 31, early warning communication module 4, alarm 5, and early warning opening and closing component 6 inside the housing 1. By setting the real-time monitoring module 31, the metering data of the power metering module 3 can be collected in real time. When the data is abnormal, the early warning communication module 4 can respond quickly. At the same time, the pressure sensor 63 and the gear block 611 in the early warning opening and closing component 6 can monitor the rotation status of the rotating shaft 61 in real time, realize the monitoring of the opening and closing of the housing door, and promptly detect metering abnormalities and illegal opening and closing behaviors.

[0021] Please see Figures 3-6 The warning opening and closing assembly 6 also includes a guide cylinder 65, which is fixed at the bottom of the housing 1. The guide post 621 is connected to the guide cylinder 65 through the guide post 621. A retaining ring 624 is provided on one side of the guide post 621, and a return spring 625 is provided on one side of the retaining ring 624. The return spring 625 is connected to one side of the fixing plate 64.

[0022] In this embodiment, the guide cylinder 65 is welded to the bottom of the housing 1 to provide guidance for the guide column 621, limit the deviation of the guide column 621 during the movement, ensure that the limiting tooth block 62 and the gear block 611 maintain a stable contact state, and avoid the pressure sensor 63 and the gear block 611 from shifting due to the shaking of the guide column 621, thus ensuring the accuracy of pressure monitoring.

[0023] In this embodiment, in the initial state, the limiting tooth block 62 at one end of the guide post 621 does not abut against the pressure sensor 63 of the gear block 611. At this time, the return spring 625 is at its original length, and the insertion part 622 passes through the fixing plate 64 by a certain distance. When monitoring is required, the guide post 621 is pushed towards the limiting tooth block 62. At this time, the return spring 625 is stretched, and the insertion part 622 moves to align with the screw cavity of the fixing plate 64. Then, it is fixed by the locking pin 623, so that the limiting tooth block 62 abuts against the pressure sensor 63 of the gear block 611. When the staff actually inspects the box 1, by pulling out the locking pin 623, the elastic deformation of the return spring 625 automatically drives the limiting tooth block 62 to separate from the gear block 611. At this time, the limiting tooth block 62 also separates from the pressure sensor 63. At this time, the gear block 611 can rotate, which makes it easy to open the movable plate 2 of the box 1, and will not trigger an alarm.

[0024] Please see Figures 1-4 The housing 1 is equipped with a movable plate 2, which is connected to the rotating shaft 61. A positioning block 21 is provided on one side of the movable plate 2, and the positioning block 21 is equipped with a fixing pin 22.

[0025] In this embodiment, the movable plate 2 is connected to the rotating shaft 61, so that the opening and closing state of the movable plate 2 is linked with the early warning opening and closing component 6. When the movable plate 2 is rotated open, it will drive the rotating shaft 61 and the gear block 611 to move synchronously, thereby triggering the pressure sensor 63 to transmit a signal to the early warning communication integrated module 4, realizing real-time monitoring and early warning of the opening and closing state of the movable plate 2, and further strengthening the safety protection system of the power metering box.

[0026] In this embodiment, the positioning block 21 is equipped with a fixing pin 22, which can fix the movable plate 2 after it is closed. At the same time, it can also mislead illegal personnel into thinking that they can open the box 1 by simply pulling out the fixing pin 22, so that they ignore the linkage between the movable plate 2 and the rotating shaft 61. When the illegal personnel pull out the fixing pin 22 and try to open the movable plate 2, the rotation of the movable plate 2 will drive the rotating shaft 61 and the gear block 611 to move synchronously, thereby triggering the pressure sensor 63 to send a signal to the early warning communication module 4, realizing an immediate early warning of abnormal opening behavior.

[0027] Please see Figures 1-3 The bottom of the box 1 is provided with a hidden frame 11, and the warning opening and closing component 6 is located in the hidden frame 11.

[0028] In this embodiment, the hidden design of the hidden frame 11 ensures that the warning opening and closing component 6 is not directly exposed to the outside of the box 1 or easily accessible areas, making it difficult for criminals to intuitively detect the position and structure of the component, thus further enhancing the security protection level of the metering box.

[0029] Among them, the electricity metering module 3 adopts the existing ADW300-HJ-D16-4GU series metering module, the real-time monitoring module 31 adopts the existing SI-EWA-PFD-RJ45 mains power monitoring module, the early warning communication integrated module 4 adopts the existing SKG18AX-09 Beidou tri-frequency communication short message module, and the alarm 5 adopts the existing 2411 model alarm. Since the above devices are all existing products, their working principles and connection technologies will not be described in detail here.

[0030] Working principle and usage process of this utility model: In the initial state, the warning opening and closing component 6 is located in the hidden frame 11 at the bottom of the box 1. At this time, the limiting tooth block 62 at one end of the guide post 621 does not abut against the pressure sensor 63 of the gear block 611, the reset spring 625 is at its original length, the insertion part 622 of the guide post 621 passes through the fixed plate 64 for a distance, the movable plate 2 is closed, and the fixing pin 22 on the positioning block 21 is inserted and locked. When monitoring is required, push the guide post 621 to move towards one end of the limiting tooth block 62. The return spring 625 is stretched by the retaining ring 624. The guide post 621 slides along the guide cylinder 65. After the insertion part 622 is aligned with the screw cavity of the protrusion of the fixing plate 64, the locking pin 623 is inserted to fix it. At this time, the limiting tooth block 62 and the pressure sensor 63 of the gear block 611 are in contact. At this time, each module is powered on and started. The real-time monitoring module 31 begins to collect data from the power metering module 3. When unauthorized personnel attempt to tamper with the electricity metering module 3, they will remove the fixing pin 22 and attempt to open the movable plate 2. At this time, the movable plate 2 will drive the rotating shaft 61 and gear block 611 to rotate. The gear block 611 will squeeze the pressure sensor 63, and the pressure signal will be transmitted to the early warning communication module 4 via the ribbon cable. The module will trigger the alarm 5 to sound an alarm and remotely send early warning information to the terminal. At the same time, it will record the abnormal time and status. Staff can discover the abnormality through the remote terminal and take immediate measures to avoid losses.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
