Description
Technical Field
[0001] This utility model relates to the field of electricity meter technology, and in particular to an electricity meter that integrates temperature monitoring and alarm functions. Background Technology
[0002] An electricity meter (also known as a kilowatt-hour meter) is a specialized instrument used to measure and record the electrical energy consumption in a power system. It is widely used in homes, industries, and commercial establishments, providing accurate data for electricity bill calculations. In electricity meter applications, the meter serves as the point of contact with the power grid, and its terminals inevitably connect to high voltage and high current, resulting in wiring joints. The quality of these connections is related to factors such as user overload conditions, installation quality, and aging. If a fault occurs in the meter terminals (e.g., poor contact), it can cause overheating and even fire. Therefore, temperature monitoring of the meter terminals is necessary.
[0003] Currently, the temperature monitoring method at the terminal of an electricity meter is as follows: temperature measurement is performed using a temperature-sensing PCB board. This means that a temperature-sensing PCB board is installed on the electricity meter and connected to the copper strip connecting the terminal. During temperature measurement, the temperature of the electricity meter terminal is monitored by the temperature-sensing PCB board monitoring the temperature of the copper strip connecting the terminal. This indirectly monitors the temperature of the terminal. However, because the copper strip connecting the terminal conducts heat, heat dissipation occurs, which affects the accuracy of the terminal temperature monitoring. Utility Model Content
[0004] The technical problem this invention aims to solve is: to address the issue that existing indirect monitoring of terminal temperature affects the accuracy of terminal temperature monitoring, this invention provides an energy meter that integrates temperature monitoring and alarm functions. By improving the structure of the energy meter, direct monitoring of the terminal temperature is achieved, thereby improving the accuracy of terminal temperature monitoring.
[0005] The technical solution adopted by this utility model to solve its technical problem is: an energy meter integrating temperature monitoring and alarm functions, comprising: an energy meter body, multiple temperature sensors, a controller, multiple audible and visual alarms, and a wireless transmission module. The energy meter body is provided with multiple terminals. The temperature sensors are installed on the energy meter body at positions relative to the terminals, and the temperature sensors monitor the temperature of the terminals. The controller and the wireless transmission module are both connected to the energy meter body. The audible and visual alarms are embedded in the energy meter body. The temperature sensors, audible and visual alarms, and the wireless transmission module are all connected to the controller. The audible and visual alarms are used to issue audible and visual alarms, and the wireless transmission module is used to send the temperature value of the terminals monitored by the temperature sensors to a remote terminal. The number of temperature sensors and the number of audible and visual alarms are equal to the number of controllers.
[0006] Therefore, by installing temperature sensors at the terminals of the electricity meter body, the temperature at those terminals can be directly monitored. Compared to the existing method of indirectly monitoring temperature by connecting copper strips to the terminals, this method is simpler in structure and easier to operate. Direct monitoring avoids monitoring errors caused by heat dissipation, thus improving the accuracy of temperature monitoring at the electricity meter body terminals. In addition, multiple temperature sensors can independently monitor the temperature of each terminal to accurately determine the location of overheated terminals in the electricity meter body, facilitating precise maintenance by repair personnel. Simultaneously, through an audible and visual alarm and a wireless transmission module, an audible and visual alarm for overheated terminals can be triggered and transmitted wirelessly to repair personnel, alerting them to the presence of overheating at the terminals on the electricity meter body and the need for timely repair.
[0007] As a further improvement to the above technical solution, it also includes a PCB board, wherein the controller and the wireless transmission module are both mounted on the PCB board, and the PCB board is mounted on the bottom of the electricity meter body.
[0008] As a further improvement to the above technical solution, it also includes: a connecting plate, wherein the PCB board is embedded in the connecting plate and the PCB board is located on the side of the connecting plate closer to the electricity meter body, and the connecting plate is connected to the electricity meter body through a snap-fit assembly.
[0009] As a further improvement to the above technical solution: multiple buckle components are provided, and the multiple buckle components are respectively located on both sides of the connecting plate.
[0010] As a further improvement to the above technical solution: the buckle assembly includes a buckle part and a locking part. The buckle part is mounted on the electricity meter body, and the locking part is mounted on the connecting plate. The buckle part and the locking part are adapted to each other. Therefore, through the cooperation of the buckle and the locking part, the installation and disassembly between the connecting plate and the electricity meter body can be realized, facilitating the assembly of the connecting plate and the electricity meter body, as well as the maintenance and repair of the PCB board, controller, and wireless transmission module on the connecting plate.
[0011] As a further improvement to the above technical solution: The connecting plate has multiple first reinforcing ribs and multiple second reinforcing ribs on the side away from the electricity meter body, and the first reinforcing ribs are connected to the second reinforcing ribs. Therefore, the first and second reinforcing ribs increase the structural strength of the connecting plate, reducing the risk of damage due to impact and improving its service life.
[0012] As a further improvement to the above technical solution: the first reinforcing rib and the second reinforcing rib are perpendicular to each other.
[0013] As a further improvement to the above technical solution: a plurality of first reinforcing ribs are distributed at equal intervals along a first direction, and a plurality of second reinforcing ribs are distributed at equal intervals along a second direction.
[0014] As a further improvement to the above technical solution, it also includes: multiple cooling fans, the cooling fans being located on the energy meter body relative to the wiring terminals; wherein: the number of cooling fans is equal to the number of wiring terminals. Thus, a one-to-one correspondence between the cooling fans and wiring terminals allows each wiring terminal to be independently equipped with a cooling fan, achieving precise heat dissipation for each terminal; the cooling fans enable the wiring terminals to switch between active and passive heat dissipation. If the cooling fans are not turned on, the wiring terminals passively dissipate heat (i.e., the wiring terminal temperature is low and can dissipate heat on its own); if the cooling fans are turned on, the wiring terminals actively dissipate heat (i.e., the wiring terminal temperature is high and cannot dissipate heat on its own; turning on the cooling fans accelerates the heat dissipation process).
[0015] As a further improvement to the above technical solution: the cooling fan is connected to the controller.
[0016] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses temperature sensors installed at the terminals of the electricity meter body to directly monitor the temperature at those terminals. Compared to existing methods that indirectly monitor temperature by connecting copper strips to the terminals, this method is simpler in structure and easier to operate. Direct monitoring avoids monitoring errors caused by heat dissipation, thus improving the accuracy of temperature monitoring at the electricity meter body terminals. Furthermore, multiple temperature sensors enable independent monitoring of the temperature of each terminal, accurately identifying the location of overheated terminals and facilitating precise repairs. Simultaneously, an audible and visual alarm and a wireless transmission module provide an audible and visual alarm for overheated terminals, which is then transmitted wirelessly to repair personnel, indicating that the terminals on the electricity meter body are overheating and require immediate repair.
[0017] 2. This utility model enables the installation and disassembly of the connecting plate and the electricity meter body through the cooperation of the buckle and the locking part, so as to facilitate the assembly of the connecting plate and the electricity meter body, as well as the maintenance of the PCB board, controller and wireless transmission module on the connecting plate.
[0018] 3. The present invention provides a one-to-one correspondence between the cooling fan and the terminal block, enabling each terminal block to be equipped with an independent cooling fan to achieve precise heat dissipation for each terminal block. The cooling fan allows the terminal block to switch between active and passive heat dissipation. If the cooling fan is not turned on, the terminal block is passively cooled (i.e., the terminal block temperature is low and it can dissipate heat on its own). If the cooling fan is turned on, the terminal block is actively cooled (i.e., the terminal block temperature is high and it cannot dissipate heat on its own; turning on the cooling fan can accelerate the heat dissipation process of the terminal block).

[0025] like Figures 1 to 5The diagram shows the preferred embodiment of this utility model. This embodiment of the energy meter integrating temperature monitoring and alarm functions includes: an energy meter body 1, multiple temperature sensors 3, a controller 4, multiple audible and visual alarms 5, and a wireless transmission module 6. The energy meter body 1 is provided with multiple terminals 2. The temperature sensors 3 are installed on the energy meter body 1 at positions relative to the terminals 2, and monitor the temperature of the terminals 2. The controller 4 and the wireless transmission module 6 are both connected to the energy meter body 1. The audible and visual alarms 5 are embedded in the energy meter body 1. The temperature sensors 3, audible and visual alarms 5, and wireless transmission module 6 are all connected to the controller 4. The audible and visual alarms 5 are used to issue audible and visual alarms, and the wireless transmission module 6 is used to send the temperature value of the terminals 2 monitored by the temperature sensors 3 to a remote terminal. The number of temperature sensors 3 and the number of audible and visual alarms 5 are equal to the number of controllers 4. Therefore, by using a temperature sensor 3 located at the terminal 2 of the electricity meter body 1, the temperature at the terminal 2 can be directly monitored. Compared to the existing method of indirectly monitoring the temperature by connecting a copper strip to the terminal 2, this method is simpler in structure and easier to operate. Direct monitoring avoids monitoring errors caused by heat dissipation, thus improving the accuracy of temperature monitoring at the terminal 2 of the electricity meter body 1. In addition, multiple temperature sensors 3 can independently monitor the temperature of each terminal 2 to accurately determine the location of the terminal 2 that has overheated on the electricity meter body 1, facilitating accurate maintenance by repair personnel. At the same time, through the audible and visual alarm 5 and the wireless transmission module 6, an audible and visual alarm for overheated terminal 2 can be triggered and sent to the repair personnel via the wireless transmission module 6 to remind them that the terminal 2 on the electricity meter body 1 is overheating and needs to be repaired in time.
[0026] Specifically, the remote terminal can be the repairman's mobile phone or the terminal display screen in the repair room.
[0027] In this embodiment, it also includes: PCB board 7, controller 4 and wireless transmission module 6 are all mounted on PCB board 7, and PCB board 7 is mounted on the bottom of the electricity meter body 1.
[0028] In this embodiment, a connecting plate 8 is also included. A PCB board 7 is embedded in the connecting plate 8, and the PCB board 7 is located on the side of the connecting plate 8 closer to the electricity meter body 1. The connecting plate 8 is connected to the electricity meter body 1 via a snap-fit assembly 9. Multiple snap-fit assemblies 9 are provided, and the multiple snap-fit assemblies 9 are respectively located on both sides of the connecting plate 8. The snap-fit assembly 9 includes a snap-fit part 901 and a locking part 902. The snap-fit part 901 is installed on the electricity meter body 1, and the locking part 902 is installed on the connecting plate 8. The snap-fit part 901 and the locking part 902 are adapted to each other. Thus, through the mutual cooperation of the snap-fit and the locking part 902, the installation and disassembly between the connecting plate 8 and the electricity meter body 1 can be realized, so as to facilitate the assembly between the connecting plate 8 and the electricity meter body 1 and the maintenance of the PCB board 7, controller 4 and wireless transmission module 6 on the connecting plate 8.
[0029] In this embodiment, a plurality of first reinforcing ribs 801 and a plurality of second reinforcing ribs 802 are provided on the side of the connecting plate 8 away from the electricity meter body 1. The first reinforcing ribs 801 and the second reinforcing ribs 802 are connected to each other; the first reinforcing ribs 801 and the second reinforcing ribs 802 are perpendicular to each other; the plurality of first reinforcing ribs 801 are distributed at equal intervals along a first direction, and the plurality of second reinforcing ribs 802 are distributed at equal intervals along a second direction. Thus, the structural strength of the connecting plate 8 can be increased by the first reinforcing ribs 801 and the second reinforcing ribs 802, thereby reducing the risk of damage to the connecting plate 8 due to impact and improving the service life of the connecting plate 8.
[0030] In this embodiment, the system further includes multiple cooling fans 10, located at positions on the energy meter body 1 relative to the terminals 2, and connected to the controller 4. The number of cooling fans 10 is equal to the number of terminals 2. Thus, each cooling fan 10 corresponds to one terminal 2, allowing each terminal 2 to be independently equipped with a cooling fan 10 for precise heat dissipation. The cooling fans 10 enable the terminals 2 to switch between active and passive heat dissipation. If the cooling fans 10 are not activated, the terminals 2 are passively cooled (i.e., the terminal 2 temperature is low and can dissipate heat on its own). If the cooling fans 10 are activated, the terminals 2 are actively cooled (i.e., the terminal 2 temperature is high and cannot dissipate heat on its own; activating the cooling fans 10 accelerates the heat dissipation process).
[0031] The process of temperature monitoring and alarm of the wiring terminal 2 of the power meter body 1 of this utility model is as follows: the temperature of the wiring terminal 2 of the power meter body 1 is monitored in real time by the temperature sensor 3. If the monitored temperature value A is less than the preset value B (the preset value B is an empirical value; a temperature value A less than the preset value B indicates that the terminal 2 is working normally and generating heat), then no alarm is needed, and the cooling fan 10 will not be turned on. If the monitored temperature value A is greater than or equal to the preset value B, the terminal 2 is in an overheated state. An audible and visual alarm is generated by the audible and visual alarm 5, and the warning information (i.e., the warning information that the terminal 2 is in an overheated state) is sent to the remote terminal through the wireless transmission module 6 so that the maintenance personnel can receive the warning information and carry out maintenance in a timely manner. At the same time, the cooling fan 10 is turned on to actively cool down the terminal 2 that is in an overheated state.
[0032] In summary, this utility model, through the temperature sensor 3 installed at the terminal 2 of the electricity meter body 1, can directly monitor the temperature at the terminal 2 of the electricity meter body 1. Compared with the existing method of indirectly monitoring the temperature by connecting the terminal 2 to a copper strip, this method has a simpler structure and is easier to operate. The direct monitoring method can avoid monitoring errors caused by heat dissipation, thereby improving the accuracy of temperature monitoring at the terminal 2 of the electricity meter body 1. In addition, multiple temperature sensors 3 can achieve independent monitoring of the temperature of each terminal 2, so as to accurately determine the location of the terminal 2 of the electricity meter body 1 that has overheated, which is convenient for maintenance personnel to perform accurate maintenance. At the same time, through the audible and visual alarm 5 and the wireless transmission module 6, the audible and visual alarm of the overheated terminal 2 can be realized and sent to the maintenance personnel through the wireless transmission module 6, so as to remind the maintenance personnel that the terminal 2 on the electricity meter body 1 has overheated and needs to be repaired in time.
[0033] The above description is based on the preferred embodiments of this utility model. Through the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined by the scope of the claims.
