Description

Technical Field

[0001] This invention relates to the field of electrical testing tools, specifically a hanging electrical testing device for live-line work. Background Technology

[0002] Voltage testing devices are specialized electrical safety tools used to detect the presence of voltage in overhead lines, cable lines, and high-voltage electrical equipment. Grounding devices are a type of temporary grounding device commonly used in power production. Installing grounding devices on the equipment and lines under maintenance is one of the safety measures to ensure safety. The purpose is to discharge residual charge, prevent sudden power surges and induced voltages that may be generated by nearby live equipment and lines, provide reliable protection for the safety of high and low voltage power transmission lines and electrical equipment maintenance, and ensure the personal safety of personnel during maintenance and repair.

[0003] Currently, when conducting power outage maintenance, the first step is usually to use a voltage detector to check for voltage. After the voltage test is completed, the voltage detector needs to be retrieved. After confirming that there is no voltage, a grounding device is used to prevent sudden power surges and potential induced voltages from nearby live equipment and lines. In addition, the voltage detector and the grounding device are two separate items, which results in workers carrying a large number of items and needing to switch between the two separate items during the work, making the operation complicated and inconvenient.

[0004] Therefore, to solve the above problems, a hanging voltage detector for live-line work is proposed. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a hanging voltage testing device for live-line work that is simple in structure, highly practical, securely mounted, and has good safety performance, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a hanging-type voltage detector for live-line work, comprising an insulating handle, an insulating rod, a voltage detector mechanism, and a hanging mechanism. The hanging mechanism is disposed on the top of the voltage detector mechanism, the voltage detector mechanism is disposed on the top of the insulating rod, the insulating rod is disposed on the top of the insulating handle, a connecting protrusion is disposed on the top of the voltage detector mechanism, a limiting block is disposed on the connecting protrusion, a first gear component is engaged with the outside of the limiting block, a second gear component and a third gear component are respectively geared to the two sides of the first gear component, a first screw is disposed on the second gear component, a limiting post is disposed on the first screw, a second screw is disposed on the third gear component, a hanging hook is disposed on the second screw, a voltage detector head is disposed in the middle inside the connecting protrusion, a voltage detector conductor is disposed at the upper end of the voltage detector head, a voltage detector metal plate is connected to the voltage detector conductor, and a cable line is attached to the upper end of the voltage detector metal plate.

[0007] Preferably, the insulating rod body includes a first insulating connecting rod, a second insulating connecting rod, a third insulating connecting rod, and a fourth insulating connecting rod. The top of the first insulating connecting rod, the second insulating connecting rod, the third insulating connecting rod, and the fourth insulating connecting rod are all provided with PVC limiting rings. The top of the fourth insulating connecting rod is provided with a connecting block, and the connecting block is fixedly connected to the voltage testing mechanism.

[0008] Preferably, the voltage testing mechanism includes a connecting post disposed at the bottom, and the connecting post is connected to the connecting block.

[0009] Preferably, the voltage testing mechanism further includes a self-test button, a voltage testing indicator light, and a speaker disposed on its outer surface.

[0010] Preferably, a grounding seat is provided on the side of the hanging mechanism. The grounding seat includes a grounding bushing disposed at the upper end of the hanging mechanism. A grounding conductive plate is disposed inside the grounding bushing and attached to the hanging hook. A connecting pipe is disposed on one side of the grounding conductive plate and is disposed at the upper end of the grounding seat.

[0011] Preferably, the grounding base is further provided with a grounding groove, and mounting columns are symmetrically arranged on the inner side of the grounding groove. Nuts are provided on the mounting columns, and grounding terminals are provided on the mounting columns through the nuts. Grounding wires are provided at the lower end of the grounding terminals.

[0012] Preferably, the mounting mechanism is symmetrically provided with a first lifting groove and a second lifting groove inside. The first lifting groove is provided with a limit post, a first screw and a first screw block. The second lifting groove is provided with a mounting hook, a mounting post and a second screw block.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention integrates a voltage detection mechanism and a mounting mechanism. By using a handheld insulated handle to lift the insulated rod, the mounting hook on the mounting mechanism is hung on the corresponding maintenance line. The hook is then connected to a grounding seat on one side of the mounting mechanism, thus establishing a connection between the grounding seat and the maintenance line. A grounding terminal is installed inside the grounding seat to achieve grounding. After the hook contacts the maintenance line, rotating the insulated rod rotates the voltage detection mechanism, causing the hook to extend or retract inwards. Simultaneously, a limiting post rises, bringing the voltage detection metal plate on the voltage detection block in the middle of the mounting mechanism into contact with the maintenance line. The voltage detection metal plate connects to a voltage detection head within the mounting mechanism via a voltage detection conductor, allowing for the detection of whether the maintenance line is energized. This effectively simplifies the voltage detection and grounding procedures for maintenance lines, improves work efficiency, enhances worker safety, and reduces maintenance time for lines and electrical equipment.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention. Example 1

The voltage testing mechanism 3 also includes a self-test button 5, a voltage testing indicator light 6, and a speaker 7 located on the outer surface, which are used to perform self-tests on the voltage testing mechanism 3. Before testing, the self-test button 5 needs to be pressed so that the voltage testing indicator light 6 flashes intermittently and the speaker 7 emits an intermittent alarm sound to confirm that the voltage testing device is working properly and to verify the reliability of the voltage testing device.

[0022] In this embodiment, the mounting mechanism 4 includes a limiting post 10 at the top, a mounting hook 11, and a voltage testing block 9 between the limiting post 10 and the mounting hook 11 at the top of the mounting mechanism 4.

The device is mounted on the maintenance line by the relative lifting of the limiting post 10 and the mounting hook 11. Furthermore, the hook-type structure allows the voltage testing device to be continuously fixed on the maintenance line without being removed, thus maintaining the voltage testing state. This overcomes the shortcomings of traditional voltage testing devices, which cannot maintain voltage testing during the period from the end of voltage testing to the installation of the grounding wire. Example 2

[0023] like Figure 1-9 As shown, this embodiment discloses a hanging-type voltage detector for live-line work, which includes an insulating handle 1, an insulating rod 2, a voltage detector 3, and a hanging mechanism 4.
