Description

Technical Field

[0001] The present invention relates to the technical field of ground wire detection and identification devices, and in particular to an intelligent ground wire detection and identification device. Background Art

[0002] In a home or commercial circuit, it is critical to correctly identify the neutral and ground wires, as incorrect connections may result in electrical failure, risk of electric shock, or failure of circuit protection devices. There are generally several ways to determine the neutral and ground wires:

[0003] 1. Color distinction: According to international or local wire color coding standards, the neutral wire is usually blue or black, while the ground wire is yellow and green. You can make a preliminary judgment by observing the color of the wire.

[0004] 2. Letter marking: The wiring terminals of regular electrical appliances are usually marked with letters, L for live wire, N for neutral wire, and E for ground wire. By looking at the markings on the device, you can identify the function of each wire.

[0005] 3. Test with a test pen: Use a test pen to test. When the power is on, touch the test pen to the wire. If the test pen lights up, it means the wire is live.

[0006] However, in many cases it is not convenient to distinguish the neutral wire and the ground wire directly through color and letter markings. The electric pen test requires the staff to hold the electric pen and touch the live wire to perform live operations, which has certain risks. Summary of the invention

DETAILED DESCRIPTION

[0027] The embodiments of the present application are described in detail below in conjunction with the drawings in the embodiments of the present application.

[0028] Example

[0029] Please refer to Figure 1-Figure 4 The present embodiment provides an intelligent ground wire detection and identification device, including an installation box 1, one side of the installation box 1 is a side panel 2, and the side panel 2 is provided with an operation hole 3; the installation box 1 is provided with a detection component, and the detection component includes a conductive contact block 4, a neon bulb 5 and a resistor block 6, and the conductive contact block 4, the neon bulb 5 and the resistor block 6 are connected in series in sequence, the conductive contact block 4 is located in the operation hole 3, the neon bulb 5 is located at the top of the installation box 1, and the resistor block 6 is located in the installation box 1. The end of the resistor block 6 away from the neon bulb 5 is connected in series with a grounded conductive block 8 through a wire, and the grounded conductive block 8 is located at the bottom of the installation box 1. A first control switch 7 is connected in series between the conductive contact block 4 and the neon bulb 5, and the first control switch 7 is located at the top of the installation box 1. The first control switch 7 is used to control the on-off of the series structure formed by the conductive contact block 4, the neon bulb 5 and the resistor block 6.

[0030] The mounting box 1 and the side plate 2 of the present embodiment are both made of insulating materials, the conductive contact block 4 and the ground conductive block 8 are both made of copper, and the neon bulb 5 and the resistor block 6 are combined to form the structure of the electric pen.

[0031] The number of detection components in this embodiment is three and they are arranged at intervals, and the number of operation holes 3 is three and they correspond to the detection components one by one. A mounting shaft 16 is provided on the top of the mounting box 1, and two indicator rods 17 are provided on the mounting shaft 16 for rotation. Since there are generally three types of electric wires, namely, live wire, neutral wire and ground wire, the three detection components and three operation holes 3 in this embodiment are respectively used for simultaneous installation and detection of the three types of electric wires, thereby improving the detection and identification efficiency. By providing two indicator rods 17, one indicator rod 17 can be set to red and the other indicator rod 17 can be set to black. In this way, after determining the live wire, the red indicator rod 17 can be rotated to align with the position of the live wire, and after determining the neutral wire, the black indicator rod 17 can be rotated to align with the position of the neutral wire, so that the staff can directly distinguish and prevent forgetting at a later time.

[0032] In actual use, the wires to be tested are powered off first, the installation box 1 is placed on the ground, the grounded conductive block 8 at the bottom of the installation box 1 is in contact with the ground, the three first control switches 7 are all disconnected, and the ends of the three wires are respectively inserted into the three operating holes 3, and the ends of the wires are in contact with the conductive contact blocks 4 in the operating holes 3. After the installation of the three wires is completed, the wires are powered on, and the staff can close the first control switches 7 one by one. If the corresponding neon bulb 5 does not light up after closing the first control switch 7, the first control switch 7 is disconnected and the next first control switch 7 is closed. When the corresponding neon bulb 5 lights up after closing the first control switch 7, it means that the wire corresponding to this neon bulb 5 is the live wire, and the position of the live wire is first determined. The judgment principle is as follows: when the live wire, the conductive contact block 4, the neon bulb 5, the resistor block 6, and the grounded conductive block 8 are connected in series and connected to the ground, a path can be formed, which is consistent with the principle of the electric pen. At this time, the neon bulb 5 can light up after being turned on.

[0033] After the position of the live wire is determined, the first control switch 7 at the live wire position is disconnected, and there are two remaining wires that need to be determined. At this time, the neutral wire of the main power switch of the wire is disconnected first. There is a load in the circuit, and the load can be an electrical device such as an incandescent lamp. The live wire will transfer the voltage to the disconnected neutral wire through the impedance of the load, and the neutral wire will be energized at this time. Continue to close the remaining two first control switches 7 according to the above steps. When the neon bulb 5 is lit, the wire corresponding to the neon bulb 5 at this position is the neutral wire, and the remaining wire is the ground wire. This makes it easy to detect and identify the ground wire to distinguish the position of the ground wire, and the staff does not need to directly touch the energized live wire, which is safer.

[0034] like Figure 1-Figure 2As shown, in some embodiments, the bottom of the grounding conductive block 8 is arc-shaped, and the grounding conductive block 8 is slidably arranged on the installation box 1 along the vertical direction. The installation box 1 is provided with a guide sliding hole 9 with an opening facing downward, and the grounding conductive block 8 is slidably arranged in the guide sliding hole 9. A spring 10 is arranged in the guide sliding hole 9, one end of the spring 10 is connected to the installation box 1, and the other end of the spring 10 is connected to the grounding conductive block 8. The present invention is provided with the guide sliding hole 9 and the spring 10, so that after the installation box 1 is placed on the ground, the spring 10 can apply a downward elastic force to the grounding conductive block 8 so that the grounding conductive block 8 is tightly against the ground, so as to facilitate electrical conduction.

[0035] like Figure 1-Figure 4 As shown, in some embodiments, a pressing seat 11 and a fixed base 13 are provided in the installation box 1, and the fixed base 13 is fixedly provided inside the installation box 1, and the pressing seat 11 is located above the fixed base 13; the conductive contact block 4 is arc-shaped and fixed to the top of the fixed base 13, and the pressing seat 11 is provided with a pressing protrusion 12 that cooperates with the conductive contact block 4; the fixed base 13 is provided with an electric push rod 14, and the pressing seat 11 is provided at the telescopic end of the electric push rod 14. A second control switch 15 is provided on the side wall of the installation box 1, and the second control switch 15 is electrically connected to the electric push rod 14. The second control switch 15 is used to control the extension and contraction of the electric push rod 14.

[0036] The pressing seat 11 and the fixed base 13 of this embodiment are made of insulating materials, and the pressing protrusion 12 can be made of a rubber block. The present invention sets an electric push rod 14 and a pressing protrusion 12. After the ends of the three wires are respectively embedded in the operating holes 3, the electric push rod 14 can be started and shortened. At this time, the electric push rod 14 pulls the pressing seat 11 to move downward and makes the pressing protrusion 12 press the wires tightly downward on the top of the conductive contact block 4, so that the wires and the conductive contact block 4 are convenient for abutting and conducting electricity. Moreover, after the wires are pressed by the pressing protrusion 12, the ends of the wires can be shielded to prevent them from being directly exposed to the outside and causing safety hazards. When the wire detection and identification is completed, the electric push rod 14 is started, and the electric push rod 14 extends and pushes the pressing seat 11 and the pressing protrusion 12 to move upward. At this time, the three wires can be pulled out.
