Description

Technical Field

[0001] The present invention belongs to the technical field of power equipment, and particularly relates to an abnormal detection device and method for an electric energy meter. Background Art

[0002] An electric energy meter is an instrument used to measure electric energy, also known as a kilowatt-hour meter, a watt-hour meter, or a kilowatt-hour meter, which refers to an instrument for measuring various electrical quantities. When using an electric energy meter, it should be noted that under low voltage (not exceeding 500 volts) and small current (tens of amperes), the electric energy meter can be directly connected to the circuit for measurement. Under high voltage or large current conditions, the electric energy meter cannot be directly connected to the line and needs to be used in conjunction with a voltage transformer or a current transformer.

[0003] When the electric energy meter is used for a long time, the voltage of the battery supplying the digital display screen inside the meter becomes low, resulting in abnormal digital display on the screen. By the time the household user notices the abnormality, a long time has passed. Ordinary users cannot detect and disassemble the battery of the electric energy meter in time for replacement, which will affect the normal reading and use of the electric energy meter. At the same time, the pulse signal lamp of the electric energy meter flashes continuously for a long time, which may also cause other abnormalities in the electric energy meter, and there is no effective detection means. Therefore, an abnormal detection device for an electric energy meter is needed. Summary of the Invention

[0007] The lightning slot consists of a transverse horizontal slot, a longitudinal inclined slot and a transition drop slot to form an annular structure; The transition drop slot is arranged at the transition between the transverse horizontal slot and the longitudinal inclined slot.

[0008] Furthermore, the battery retaining ring is arranged on the connecting plate, and the connecting plate is connected to the linkage shaft through an L-shaped rod; The L-shaped protective plate is provided with a battery holder, and the battery holder is in contact and cooperation with the battery retaining ring; The battery holder is connected to the electronic display screen through a power supply wire.

[0009] Furthermore, the battery retaining ring is provided with a first avoidance hole; The battery holder is provided with a second avoidance hole; A top plate is slidably connected in the second avoidance hole, and the top plate is connected to the protective telescopic rod through a U-shaped plate.

[0011] Furthermore, an L-shaped exhaust pipe and a heat dissipation plate are arranged inside the electric energy meter housing; The heat dissipation plate is in contact and cooperation with the control main board.

[0012] Furthermore, a discharge hole is arranged between the electric energy meter housing and the L-shaped protective plate; The surface of the battery retaining ring is attached to the L-shaped protective plate.

[0013] Furthermore, an insulating sleeve is arranged at the end of the top plate; The insulating sleeve is in contact and cooperation with the button battery.

[0014] Furthermore, a PLC controller is arranged inside the protection cabinet; the PLC controller is respectively connected to the vision detection camera, the alarm, the electric telescopic rod and the electric first synchronous pulley.

[0015] In the second aspect of the present invention, a method for detecting abnormal conditions of an electric energy meter is provided, including the following steps: Drive the synchronous belt through the electric first synchronous pulley to drive the vision detection camera to move along the surface of the electric energy meter housing; The vision detection camera continuously acquires image information of the electronic display screen and the pulse signal lamp; when it is detected that the pulse signal lamp continuously flashes for more than a preset threshold, the PLC controller triggers the alarm to give an alarm; when it is detected that the numbers on the electronic display screen are blurred, the electric telescopic rod drives the driving rod to move; The driving rod drives the rotating disc to rotate through the sliding column and the ball head; The rotating disc drives the battery retaining ring to rotate to the position of the discharge hole through the L-shaped rod; The top plate pushes the failed button battery out of the battery retaining ring under the drive of the protective telescopic rod; The new button battery rotates with the rotating disc to the battery seat position to complete the power supply connection; The control main board dissipates heat through the heat dissipation plate and the L-shaped exhaust pipe; After the abnormal handling is completed, the vision detection camera returns to the initial position to continue monitoring.

[0018] In the present invention, when the ball head moves in the horizontal horizontal groove, the horizontal horizontal groove and the driving rod remain horizontal, and the rotating disc does not rotate. The reset of the ball head is blocked by the excessive descending groove and enters the interior of the lightning groove to move. At this time, the rotating disc is driven to rotate. When the surface of the new button battery contacts the surface of the battery seat, the battery seat supplies power to the surface of the electronic display screen through the power supply line to ensure the normal power supply of the electronic display screen. When the abnormality of the electronic display screen is detected and is not clear, the button battery is automatically replaced, and the user does not need to manually disassemble the electric energy meter housing to replace the button battery, which will not hinder the normal digital reading.

[0043] Embodiment 2 An electric energy meter abnormality detection method, based on the electric energy meter abnormality detection device of the above embodiment, the method includes the following steps: a. Drive the synchronous belt 8 through the electric first synchronous pulley 4 to drive the vision detection camera 10 to move along the surface of the electric energy meter housing 11; b. The vision detection camera 10 continuously acquires image information of the electronic display screen 12 and the pulse signal lamp 13; when it detects that the pulse signal lamp 13 flashes continuously for more than a preset threshold, the PLC controller 14 triggers the alarm 2 to issue an alarm; when it detects that the numbers on the electronic display screen 12 are blurred, the electric telescopic rod 22 drives the driving rod 36 to move; c. The driving rod 36 pushes the rotating disk 30 to rotate through the sliding column 38 and the ball head 41; d. The rotating disk 30 drives the battery retaining ring 31 to rotate to the position of the discharge hole 46 through the L-shaped rod 23; e. The top plate 25 ejects the failed button battery 32 out of the battery retaining ring 31 under the drive of the protection telescopic rod 28; f.

The control main board 18 dissipates heat through the heat dissipation plate 17 and the L-shaped exhaust pipe 19; h. After the abnormality handling is completed, the vision detection camera 10 returns to the initial position to continue monitoring.

[0044] In a more specific embodiment, the method includes the following steps: S1. When detecting the pulse signal lamp 13, the mounting plate 9 drives the vision detection camera 10 to move, and detects the electronic display screen 12 and the pulse signal lamp 13. When the vision detection camera 10 detects that the corresponding pulse signal lamp 13 flashes abnormally for a long time, the electric first synchronous pulley 4 stops rotating, and the PLC controller 14 controls the alarm 2 to give an alarm through an electric signal, informing the external personnel that there is an abnormality in the main body of the electric energy meter housing 11, and it is necessary to open the flip door 3 for disassembly and maintenance.

Subsequently, the equipment maintenance personnel can open the flip door 3 to recycle it.

[0046] S3. The driving rod 36 drives the sliding column 38 and the ball head 41 as a whole through the sleeve 37. At this time, when the ball head 41 moves in the horizontal transverse groove 44, the horizontal transverse groove 44 is horizontal with the driving rod 36, and the rotating disc 30 does not rotate. When the driving rod 36 resets, the ball head 41 is blocked by the excessive drop groove 40 and enters the interior of the lightning groove 43 to move. At this time, the rotating disc 30 is driven to rotate. When the surface of the new button battery 32 contacts the surface of the battery holder 26, the battery holder 26 supplies power to the surface of the electronic display screen 12 through the power supply wire 20 to ensure the normal power supply of the electronic display screen 12 and not hinder the normal digital reading.
