Description

Technical Field

[0001] The present invention relates to the technical field of rapid inspection instruments, and particularly to a rapid inspection instrument for the reverse connection of the incoming and outgoing lines of an electric energy meter. Background Art

[0002] An electric energy meter is an instrument used to measure electric energy, also known as a watt-hour meter, a fire 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. Currently, most of the electric energy meters in use are electronic, and when the incoming and outgoing lines of an electronic electric energy meter are connected in reverse, the situation of abnormal power consumption will occur. When connecting electricity, due to the large workload, electricians often connect the lines in reverse, which affects the electricity consumption of residents or enterprises and cannot meet the usage requirements. Summary of the Invention

[0003] The purpose of the present invention is to solve the problem that when connecting electricity, due to the large workload, electricians often connect the lines in reverse, which affects the electricity consumption of residents or enterprises and cannot meet the usage requirements, and to propose a rapid inspection instrument for the reverse connection of the incoming and outgoing lines of an electric energy meter.

[0004] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0005] A rapid inspection instrument for the reverse connection of the incoming and outgoing lines of an electric energy meter, including an inspection instrument body. The inspection instrument body is a hollow structure. At the bottom end of the inner wall of the inspection instrument body, there is an installation seat. A rotary motor is arranged on the installation seat. The rotary motor is connected to a driven shaft through an output shaft. An activity through-hole is opened on the inspection instrument body. The driven shaft extends to the outside of the inspection instrument body through the activity through-hole, and the driven shaft is movably arranged in the activity through-hole. One end of the driven shaft extending to the outside of the inspection instrument body is connected to a connecting rod, and one end of the connecting rod away from the driven shaft is connected to an indicating ball. At the top end of the inner wall of the inspection instrument body, there is a rectifier, and on one side of the inner wall of the inspection instrument body, there is an installation bracket.

[0006] Preferably, a porcelain cylinder is sleeved on the installation bracket. A conductive coil is wound around the porcelain cylinder. A conductive part is sleeved on the conductive coil. A first through-hole is opened on the conductive part. The conductive part is sleeved on the conductive coil through the first through-hole. At the top end of the conductive part, there is a movable rod, and the movable rod is made of insulating material. An activity channel is opened on the inspection instrument body, and the movable rod extends to the outside of the inspection instrument body through the activity channel, and the movable rod is movably arranged in the activity channel.

[0007] Preferably, a first bracket is provided above the mounting bracket, and the first bracket is provided on the inner wall of the inspection instrument body. The first bracket is a hollow structure. A second bracket is movably provided inside the first bracket, and the second bracket extends outside the first bracket. One end of the second bracket extending outside the first bracket is provided on the movable rod. Symmetric sliding grooves are formed on both sides of the inner wall of the first bracket, and symmetric sliding blocks are provided on both sides of the second bracket. The sliding blocks are movably provided in the sliding grooves.

[0008] Preferably, a second through hole is formed on one side of the first bracket close to the movable rod, and the second bracket extends outside the first bracket through the second through hole. The second bracket is movably provided in the second through hole.

[0009] Preferably, a first wire clamp and a second wire clamp are provided above the device body, and the first wire clamp and the second wire clamp are respectively connected to a rectifier through wires for telecommunication.

[0011] Preferably, the positive pole of the rectifier is connected to the conductive coil through a wire, and the conductive part is connected to the positive pole of the rotary motor through a wire. The negative pole of the rotary motor is connected to the negative pole of the rectifier through a wire.

[0012] In the present invention, the quick inspection instrument for the reverse connection of the incoming and outgoing wires of the electric energy meter can drive the indicating ball to rotate by adding a rotary motor and a rectifier, so as to judge the reverse current according to the rotation direction of the indicating ball. At the same time, the movable rod drives the conductive part to move, and the conductive part moves on the conductive coil, so as to change the number of turns of the conductive coil connected to the circuit, so as to change the magnitude of the current contacting the rotary motor.

At the same time, by moving the conductive part on the conductive coil, it can avoid the situation that the rotation speed of the rotary motor is too fast to judge the rotation direction of the indicating ball, which is convenient to use.

The inspection instrument body 1 is a hollow structure. At the bottom end of the inner wall of the inspection instrument body 1, there is a mounting seat 2. A rotating motor 3 is provided on the mounting seat 2. The rotating motor 3 is connected to a driven shaft 4 through an output shaft. And a movable through hole 5 is opened on the inspection instrument body 1. The driven shaft 4 extends to the outside of the inspection instrument body 1 through the movable through hole 5. And the driven shaft 4 is movably arranged in the movable through hole 5. One end of the driven shaft 4 extending to the outside of the inspection instrument body 1 is connected to a connecting rod 6. And one end of the connecting rod 6 far from the driven shaft 4 is connected to an indicating ball 7. A rectifier 8 is provided at the top end of the inner wall of the inspection instrument body 1. And a mounting bracket 9 is provided on one side of the inner wall of the inspection instrument body 1.

[0020] In the present invention, a porcelain cylinder 10 is sleeved on the mounting bracket 9. A conductive coil 11 is wound around the porcelain cylinder 10. A conductive part 12 is sleeved on the conductive coil 11. And a first through hole 13 is opened on the conductive part 12. The conductive part 12 is sleeved on the conductive coil 11 through the first through hole 13. A movable rod 14 is provided at the top end of the conductive part 12. And the movable rod 14 is made of an insulating material. A movable channel 15 is opened on the inspection instrument body 1. And the movable rod 14 extends to the outside of the inspection instrument body 1 through the movable channel 15. The movable rod 14 is movably arranged in the movable channel 15.

[0021] In the present invention, a first support 16 is provided above the mounting bracket 9. And the first support 16 is arranged on the inner wall of the inspection instrument body 1. The first support 16 is a hollow structure. A second support 17 is movably arranged inside the first support 16. And the second support 17 extends to the outside of the first support 16. One end of the second support 17 extending to the outside of the first support 16 is arranged on the movable rod 14. Sliding grooves 18 are symmetrically opened on both sides of the inner wall of the first support 16. And sliders 19 are symmetrically provided on both sides of the second support 17. The sliders 19 are movably arranged in the sliding grooves 18.

[0022] In the present invention, a second through-hole is provided on one side of the first bracket 16 close to the movable rod 14, and the second bracket 17 extends outside the first bracket 16 through the second through-hole. The second bracket 17 is movably arranged in the second through-hole. Above the device body 1, a first wire clamp 20 and a second wire clamp 21 are provided.
