Description

Technical Field

[0001] This utility model relates to the field of railway power supply technology, and in particular to a grounding sealing line induced transient electric vector monitoring device. Background Technology

[0002] During the operation and maintenance of railway power supply systems, grounding sealing is a core measure to ensure the safety of workers. However, the railway work environment is characterized by long parallel high-voltage lines and short phase-to-phase distances. Alternating magnetic fields such as electromagnetic induction and electrostatic induction can induce significant currents in overhead lines during power outages. This induced current not only poses a potential threat to the lives of on-site workers but may also interfere with the normal operation of power equipment. Therefore, accurate monitoring of the induced current in the power supply sealing line is crucial.

[0003] Existing methods for detecting induced current rely solely on simple measurements with a multimeter, which cannot quantify the induced current value in real time. This results in the grounding effectiveness assessment being entirely dependent on the experience of the workers, leading to insufficient accuracy and reliability. Furthermore, while there is no danger when using a multimeter for testing, when workers begin construction and the induced current suddenly increases, the workers may not be able to detect the risk in time, posing a very high risk of electric shock. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a grounding sealing line induced transient electric vector monitoring device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A grounding sealing line induced transient electric vector monitoring device includes a device body, a base fixedly installed at the bottom of the device body, a plurality of bolt mounting holes on the base, a solar panel installed at the top of the device body, an antenna installed at one end of the device body, and a sensing and acquisition component installed at the other end of the device body.

[0006] Preferably, the top of the main body of the device has a mounting groove, one end of the solar panel is hinged to one end of the mounting groove, the other end of the solar panel has a U-shaped groove, a U-shaped seat is fixedly installed in the U-shaped groove, a push-pull block is slidably engaged in the U-shaped seat, waist-shaped grooves are opened on both sides of the inner wall of the U-shaped seat, and push-pull rods are fixedly installed on both sides of the outer wall of the push-pull block. The push-pull rods are slidably engaged in the waist-shaped grooves, and a screw is threaded through the push-pull block. The bottom of the screw is rotatably engaged in the bottom of the mounting groove.

[0007] Preferably, the diameter of the push-pull rod is equal to the inner height of the waist-shaped groove, and a hexagonal knob is fixedly installed on the top of the screw.

[0008] Preferably, the sensing and acquisition component includes a mounting shell, a fixed sensing coil is fixedly sleeved at one end of the mounting shell, and a rotating groove is opened at the other end of the mounting shell. A rotating shaft is rotatably sleeved in the rotating groove, and one end of a movable sensing coil is fixedly sleeved on the rotating shaft.

[0011] The grounding seal induced transient electric vector monitoring device proposed in this utility model has the following advantages: 1. The main body of the device is fixed to the grounding sealing line by the base. By rotating the screw, the screw thread drives the push-pull block to move up and down. The push-pull block pushes and pulls the waist-shaped groove through the push-pull rod, thereby making the solar panel rotate and adjusting the angle of the solar panel so that the solar panel can fully contact the sunlight and maintain the power supply of the device. 2.
