Description

Technical Field

[0001] The present invention relates to the technical field of electric meter data collection and communication, and more specifically, to a three-phase electric energy meter data collection 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, the patent with publication number CN221688286U discloses a photovoltaic collector line protector, including a carrier board, a shell installed on the carrier board, a leakage protection module installed on the shell, a wiring terminal arranged at the lower end of the shell, a protective seat installed at the bottom of the shell, the protective seat is arranged on one side of the wiring terminal, and a release drive is arranged at the upper end of the shell. Smoke sensors are installed on both sides of the protective seat, a plurality of equidistantly distributed heat dissipation slots are opened on the guide sleeve, and the heat dissipation slots all penetrate the guide sleeve, and a connecting seat is fixedly installed on the guide sleeve, which is connected to the wire through the wiring terminal;

[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 performed through 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 from the nozzles on both sides, thereby performing a fire extinguishing operation on 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 cause damage to 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 communication unit, aiming to solve the problems raised in the above-mentioned background technology.

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

[0007] The conversion assembly includes a side plate arranged in a shell, the outer side of the shell is rotatably connected with a cover plate through a hinge, a support plate is arranged at the bottom of the side plate, the support plate is snap-connected with the side plate, 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 arranged on one side of the support plate, the guardrail is located on the outer side of the side plate, and the top of the guardrail extends to the top of the inner cavity of the shell.

[0008] Two protectors are arranged in the side panel, and a converter is arranged inside each of the protectors, a plurality of pins are welded on the top of the converter, a hollow cylinder is arranged above the converter, a gasket is installed in the hollow cylinder by bolts, a plurality of detection terminals are plugged into the top of the gasket, a connecting plate is welded on the bottom of the plurality of detection terminals, and a voltage detector is arranged on one side of each of the connection plates, a limit block is arranged on the top of the gasket, a rotating disk is clamped on the limit block, an elastic transmission part is arranged on the rotating disk, one end of the plurality of pins respectively 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 with 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 is displaced, 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 an extrusion force and deform 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 switching the docking and ensuring 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 inserted on 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 on 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 by the collection connector is detected by thermistors and sensors on the main line. Once the current and voltage are abnormally large and damage the collection 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 the first gear is driven to rotate by starting the micro motor. When the first gear rotates, the second gear is driven to rotate, and then the signal transmission rod and the limit block are rotated, and the signal is transmitted to the transmission board through the signal transmission rod. When the elastic transmission part does not contact the detection terminal, the signal is disconnected, and 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 the sensor by connecting the collected wiring harness with the collection connector. Once the current and voltage are abnormally large and damage the collection connector, the thermistor disconnects the circuit to avoid the internal fuse from breaking and being damaged;

[0014] 2. The present invention is responsible for converting analog signals into digital signals through a converter, and starts a micro motor to drive the first gear to rotate. When the first gear rotates, it drives the second gear to rotate, and then the signal transmission rod and the limit block rotate. When the limit block rotates, it drives the rotating disk to rotate and causes the elastic transmission member to move. When the elastic transmission member moves, 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;

[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 does not contact 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 of restoring communication after docking, and avoiding large switching docking errors;

[0016] 4. When the elastic transmission member of the present invention approaches the detection terminal, the elastic transmission member generates an extrusion force and deforms through the limit of the detection terminal through the torque during rotation, which makes it easy for the elastic transmission member to closely contact the detection terminal, accurately switch the docking and ensure the stability of 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 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, and accurately switch the docking and data transmission. The signal is disconnected when the elastic transmission part is not in contact with the detection terminal. The elastic transmission part can accurately contact with 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 - Fig.10 A three-phase electric energy meter data acquisition communication unit shown in the figure, through the conversion component set on the shell 1, the overload circuit is disconnected through the thermistor 301 to avoid the internal fuse from breaking and damaging. When the elastic transmission member 210 is displaced, it will contact 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 will generate extrusion force and deformation through the limit of the detection terminal 205 through the torque during rotation, which makes it easy for the elastic transmission member 210 to closely contact the detection terminal 205, accurately switch the docking and the stability during data transmission. When the elastic transmission member 210 is not in contact with the detection terminal 205, the signal is disconnected. Through the elastic transmission member 210, it can accurately contact with each detection terminal 205, which is easy to switch automatically and with high accuracy, ensuring high efficiency of restoring communication after docking, avoiding large switching docking errors, and 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 rotatably connected to a cover plate 102 through a hinge. A support plate 103 is arranged at the bottom of the side panel 101, and the support plate 103 is snap-connected with the side panel 101. Limiting covers 104 are arranged at both ends of the support plate 103, and each limiting cover 104 is respectively located at the bottom of the corresponding protector 2. A guardrail 105 is fixedly arranged 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 arranged in the side plate 101, and a converter 201 is arranged inside each protector 2. Several pins 202 are welded on the top of the converter 201. A hollow cylinder 203 is arranged 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 arranged on one side of each connecting plate 206. A limit block 208 is arranged 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 arranged on the rotating disk 209. One end of the multiple pins 202 respectively 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, a thermistor 301 is provided on the collection connector 3, a sensor 302 is provided at the bottom of the thermistor 301, and 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, and 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, and a protective cover 305 is fixedly provided on the top of the docking cover 304. The protective cover 305 is located on the top of the signal transmission rod 303. The protective sleeve 305 is rotatably connected to the signal transmission rod 303, a transmission plate 306 is inserted on the top of the protective sleeve 305, a micro motor 307 is arranged on one side of the signal transmission rod 303, the micro motor 307 is embedded in the bottom of the docking cover 304, a rotating shaft is fixedly arranged on the output end of the micro motor 307, a first gear 308 is fixedly arranged on the rotating shaft, a second gear 309 is arranged 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 meshed with the first gear 308.

[0040] When the above structure is used, the main line is detected by the thermistor 301 and the sensor 302 through the collection harness connected to the collection connector 3. Once the current or voltage is abnormally large and damages the collection connector 3, the circuit is disconnected through the thermistor 301 to avoid the internal fuse from breaking and being damaged.

[0041] And each circuit 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. By starting the micro motor 307, the first gear 308 is driven to rotate. When the first gear 308 rotates, it drives the second gear 309 to rotate, and then the signal transmission rod 303 and the limit block 208 are rotated. 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 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.

[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 has high accuracy, ensuring high efficiency in restoring communication after docking and avoiding large switching docking errors.

[0043] And when the elastic transmission member 210 approaches the detection terminal 205, the elastic transmission member 210 will generate an 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 member 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 communication unit, which disconnects the overload circuit through the thermistor 301 to avoid the internal fuse from breaking and being damaged. When the elastic transmission member 210 is displaced, it will contact 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 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 member 210 to closely contact the detection terminal 205, accurately switch the docking and ensure the 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 with high accuracy, ensuring high efficiency in restoring communication after docking and avoiding large switching docking errors.
