Description

Technical Field

[0001] The present invention relates to the technical field of electric meter data acquisition and communication, and more particularly to a three-phase electric energy meter data acquisition and communication unit. Background Art

[0002] The three-phase electricity meter data acquisition and communication unit is an important component of the three-phase electricity meter. It is responsible for realizing the collection and communication functions of electricity data. The three-phase electricity meter data acquisition and communication unit refers to a functional module integrated in the three-phase electricity meter, which is used to collect electricity data (such as voltage, current, power, etc.) in the power system and transmit these data to the host computer, cloud platform or other monitoring systems through communication.

[0003] Among them, patent publication number CN221688286U discloses a photovoltaic collector line protector, comprising a carrier board mounted with a housing, a leakage protection module mounted on the housing, wiring terminals at the lower end of the housing, a protective seat mounted at the bottom of the housing, the protective seat being positioned to one side of the wiring terminals, and a trip actuator mounted at the upper end of the housing. Smoke sensors are mounted on both sides of the protective seat, a guide sleeve is provided with multiple equidistantly distributed heat dissipation slots that extend through the guide sleeve, and a connector is fixedly mounted on the guide sleeve, connected to the wires via the wiring terminals.

[0004] When this structure is in use, smoke sensors are set up to detect smoke at the wiring terminals and wires, and the smoke sensor is used for detection. When smoke is detected, the fire extinguishing function is executed by the fire extinguishing mechanism. The pump body pumps the carbon dioxide gas filled in the pump body into the air duct, and then discharges it through the nozzles on both sides, thereby extinguishing the fire at the wiring terminals and wires. However, this structure is not easy to quickly disconnect the emergency protection circuit when in use, nor is it easy to switch between various lines. In addition, the voltage and current that the electric energy meter needs to measure are usually high. Direct measurement will not only damage the equipment, but also affect the accuracy of the measurement, making the device inconvenient when in use. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a three-phase electric energy meter data acquisition and communication unit, which aims to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a three-phase electric energy meter data acquisition and communication unit, comprising a housing, on which a conversion component is provided.

[0007] The conversion assembly includes a side panel arranged in the shell, the outer side of the shell is connected to a cover plate by a hinge, the bottom of the side panel is provided with a support plate, the support plate is snap-connected to the side panel, both ends of the support plate are provided with a limit cover, and each limit cover is respectively located at the bottom of the corresponding protector, a guardrail is fixedly provided on one side of the support plate, the guardrail is located on the outer side of the side panel, and the top of the guardrail extends to the top of the inner cavity of the shell.

[0008] Two protectors are provided in the side panel, and a converter is provided inside each of the protectors. Several pins are welded on the top of the converter, and a hollow cylinder is provided above the converter. A gasket is installed in the hollow cylinder by bolts, and several detection terminals are plugged into the top of the gasket. Connecting plates are welded on the bottoms of multiple detection terminals, and a voltage detector is provided on one side of each connecting plate. A limiting block is provided on the top of the gasket, and a rotating disk is clamped on the limiting block. An elastic transmission part is provided on the rotating disk, and one end of the multiple pins extends to one side of the corresponding connecting plate and is clamped with the connecting plate, and the elastic transmission part extends to the top of the detection terminal and contacts the detection terminal.

[0009] It can be seen that in the above technical solution, when the limit block rotates, it drives the rotating disk to rotate and causes the elastic transmission part to displace. When the elastic transmission part displaces, it will contact the corresponding detection terminals one by one, so that the digital signals transmitted by the pins and the connecting board can be transmitted to the rotating disk. When the elastic transmission part approaches the detection terminal, the elastic transmission part will generate extrusion force and deformation through the torque during rotation through the limit of the detection terminal, which makes it easy for the elastic transmission part to be in close contact with the detection terminal, accurately switch the docking and ensure stability during data transmission.

[0010] A collection connector is provided on one side of the converter, a thermistor is provided on the collection connector, a sensor is provided at the bottom of the thermistor, the sensor is sleeved on the outside of the collection connector, a signal transmission rod is plugged into the top of the limit block, a docking cover is sleeved on the outside of the signal transmission rod, the docking cover is installed on the top of the protector, a protective cover is fixedly provided on the top of the docking cover, the protective cover is located at the top of the signal transmission rod and is rotatably connected to the signal transmission rod, a transmission plate is plugged into the top of the protective cover, a micro motor is provided on one side of the signal transmission rod, the micro motor is embedded in the bottom of the docking cover, a rotating shaft is fixedly provided at the output end of the micro motor, a first gear is fixedly provided on the rotating shaft, a second gear is provided on one side of the first gear, the second gear is fixed on the signal transmission rod, and the second gear is meshed with the first gear.

[0011] It can be seen that in the above technical solution, the wiring harness collected through the acquisition connector is detected by the thermistor and sensor on the main line. Once the current and voltage are abnormally large and damage the acquisition connector, the circuit is disconnected by the thermistor to avoid the internal fuse from breaking and being damaged. In addition, each line is connected to the converter and combed through each pin. The converter is responsible for converting the analog signal into a digital signal, and drives the first gear to rotate by starting the micro motor. When the first gear rotates, it drives the second gear to rotate, and then rotates the signal transmission rod and the limit block, which is transmitted to the transmission plate through the signal transmission rod. When the elastic transmission part does not contact the detection terminal, the signal is disconnected. The elastic transmission part can accurately contact each detection terminal, which is easy to switch automatically and with high accuracy, ensuring high efficiency in restoring communication after docking, and avoiding large switching docking errors.

[0012] Technical effects and advantages of the present invention:

[0013] 1. The present invention detects the main line through the thermistor and sensor by connecting the collected wire harness with the collection connector. Once the current or voltage is abnormally large and damages the collection connector, the thermistor disconnects the circuit to avoid the internal fuse from breaking and being damaged.

[0014] 2. The present invention uses a converter to convert analog signals into digital signals. The micro motor is activated to drive the first gear to rotate. The rotation of the first gear drives the second gear to rotate, which in turn causes the signal transmission rod and the limit block to rotate. The rotation of the limit block drives the rotating disk to rotate and causes the elastic transmission member to displace. When the elastic transmission member displaces, it contacts the corresponding detection terminals one by one, so that the digital signals transmitted by the pins and the connecting plate can be transmitted to the rotating disk.

[0015] 3. The present invention transmits the signal to the transmission board through the signal transmission rod, and disconnects the signal when the elastic transmission member is not in contact with the detection terminal. The elastic transmission member can accurately contact each detection terminal, which is easy to switch automatically and has high accuracy, ensuring high efficiency in restoring communication after docking and avoiding large switching and docking errors.

[0016] 4. When the elastic transmission member of the present invention approaches the detection terminal, the torque during rotation of the elastic transmission member generates an extrusion force and deforms through the limit of the detection terminal, making it easier for the elastic transmission member to closely contact the detection terminal, accurately switching the docking and ensuring stability during data transmission;

[0017] To sum up, through the corresponding coordinated use of various structures, the overload circuit is disconnected by the thermistor to avoid the internal fuse from breaking and damaging. When the elastic transmission part is displaced, it will contact the corresponding detection terminals one by one, so that the digital signal transmitted by the pin and the connecting plate can be transmitted to the rotating disk. The elastic transmission part will generate extrusion force and deformation through the limit of the detection terminal through the torque during rotation, which makes it easy for the elastic transmission part to be in close contact with the detection terminal, accurately switching the docking and data transmission. When the elastic transmission part is not in contact with the detection terminal, the signal is disconnected. The elastic transmission part can accurately contact each detection terminal, which is easy to switch automatically and with high accuracy, ensuring high efficiency in restoring communication after docking, and avoiding large switching docking errors.

[0036] As attached Figure 1 - Figure 10 The data acquisition and communication unit of a three-phase electric energy meter shown in the figure disconnects the overload circuit through the thermistor 301 through the conversion component provided on the housing 1, thereby preventing the internal fuse from breaking and being damaged. When the elastic transmission member 210 is displaced, it contacts the corresponding detection terminals 205 one by one, so that the digital signal transmitted by the pin 202 and the connecting plate 206 can be transmitted to the rotating disk 209. The elastic transmission member 210 generates an extrusion force and deforms through the limit of the detection terminal 205 due to the torque during rotation, which makes it easy for the elastic transmission member 210 to closely contact the detection terminal 205, accurately switching and docking, and ensuring stability during data transmission. When the elastic transmission member 210 is not in contact with the detection terminal 205, the signal is disconnected. The elastic transmission member 210 can accurately contact each detection terminal 205, which is easy to switch automatically and accurately, ensuring high efficiency in restoring communication after docking, and avoiding large switching and docking errors. The specific structure of the component is set as follows;

[0037] The conversion assembly includes a side panel 101 arranged in the shell 1, and the outer side of the shell 1 is connected to a cover plate 102 by a hinge. A support plate 103 is provided at the bottom of the side panel 101, and the support plate 103 is snap-connected to the side panel 101. Both ends of the support plate 103 are provided with a limit cover 104, and each limit cover 104 is respectively located at the bottom of the corresponding protector 2. A guardrail 105 is fixedly provided on one side of the support plate 103, and the guardrail 105 is located on the outer side of the side panel 101. The top of the guardrail 105 extends to the top of the inner cavity of the shell 1.

[0038] Two protectors 2 are provided in the side panel 101, and a converter 201 is provided inside each protector 2. Several pins 202 are welded on the top of the converter 201. A hollow cylinder 203 is provided above the converter 201. A gasket 204 is installed in the hollow cylinder 203 by bolts. Several detection terminals 205 are plugged into the top of the gasket 204. Connecting plates 206 are welded on the bottoms of the multiple detection terminals 205, and a voltage detector 207 is provided on one side of each connecting plate 206. A limit block 208 is provided on the top of the gasket 204, and a rotating disk 209 is clamped on the limit block 208. An elastic transmission member 210 is provided on the rotating disk 209. One end of the multiple pins 202 extends to one side of the corresponding connecting plate 206 and is clamped with the connecting plate 206. The elastic transmission member 210 extends to the top of the detection terminal 205 and contacts the detection terminal 205.

[0039] A collection connector 3 is provided on one side of the converter 201, and a thermistor 301 is provided on the collection connector 3. A sensor 302 is provided at the bottom of the thermistor 301. The sensor 302 is sleeved on the outside of the collection connector 3. A signal transmission rod 303 is plugged into the top of the limit block 208. A docking cover 304 is sleeved on the outside of the signal transmission rod 303. The docking cover 304 is installed on the top of the protector 2. A protective cover 305 is fixed on the top of the docking cover 304. The protective cover 305 is located on the top of the signal transmission rod 303. It is rotatably connected to the signal transmission rod 303, a transmission plate 306 is inserted into the top of the protective sleeve 305, a micro motor 307 is provided on one side of the signal transmission rod 303, the micro motor 307 is embedded in the bottom of the docking cover 304, and a rotating shaft is fixedly provided at the output end of the micro motor 307, a first gear 308 is fixedly provided on the rotating shaft, a second gear 309 is provided on one side of the first gear 308, the second gear 309 is fixed on the signal transmission rod 303, and the second gear 309 is engaged with the first gear 308.

[0040] According to the above structure, when in use, the wiring harness collected by the collection connector 3 is connected to the main line for detection via the thermistor 301 and the sensor 302. Once the current or voltage is abnormally large and damages the collection connector 3, the circuit is disconnected via the thermistor 301 to avoid the internal fuse from breaking and being damaged.

[0041] And each line is connected to the converter 201 and combed through each pin 202. The converter 201 is responsible for converting the analog signal into a digital signal, and drives the first gear 308 to rotate by starting the micro motor 307. When the first gear 308 rotates, it drives the second gear 309 to rotate, and then causes the signal transmission rod 303 and the limit block 208 to rotate. When the limit block 208 rotates, it drives the rotating disk 209 to rotate and causes the elastic transmission member 210 to move. When the elastic transmission member 210 moves, it will contact the corresponding detection terminal 205 one by one, so that the digital signal transmitted by the pin 202 and the connecting plate 206 can be transmitted to the rotating disk 209.

[0042] At the same time, it is transmitted to the transmission plate 306 through the signal transmission rod 303, and when the elastic transmission member 210 is not in contact with the detection terminal 205, the signal is disconnected. The elastic transmission member 210 can accurately contact each detection terminal 205, which is easy to switch automatically and with high accuracy, ensuring high efficiency in restoring communication after docking and avoiding large switching docking errors.

[0043] And when the elastic transmission part 210 approaches the detection terminal 205, the elastic transmission part 210 will generate extrusion force and deform through the torque during rotation through the limit of the detection terminal 205, which makes it easy for the elastic transmission part 210 to closely contact the detection terminal 205, accurately switching the docking and ensuring stability during data transmission.

[0044] Different from the prior art, the present application discloses a three-phase electric energy meter data acquisition and communication unit, which disconnects the overload circuit through the thermistor 301 to prevent the internal fuse from breaking and being damaged. When the elastic transmission part 210 is displaced, it will contact the corresponding detection terminal 205 one by one, so that the digital signal transmitted by the pin 202 and the connecting plate 206 can be transmitted to the rotating disk 209. The elastic transmission part 210 will generate an extrusion force and deform through the limit of the detection terminal 205 through the torque during rotation, which makes it easy for the elastic transmission part 210 to closely contact the detection terminal 205, accurately switch the docking and ensure stability during data transmission. When the elastic transmission part 210 is not in contact with the detection terminal 205, the signal is disconnected. The elastic transmission part 210 can accurately contact each detection terminal 205, which is easy to switch automatically and with high accuracy, ensuring high efficiency in restoring communication after docking and avoiding large switching docking errors.
