Description

Technical Field

[0001] The utility model relates to the technical field of grounding equipment, in particular to a grounding sensor for a grounding device grounding pin. Background Art

[0002] Currently, during power outages and maintenance, to prevent accidental power transmission or induced current from causing electric shock to workers, a short-circuit grounding wire is typically placed on the line, short-circuiting the line directly to the ground. If the grounding pin is not inserted deep enough into the ground during use, the grounding resistance will be excessive, resulting in poor grounding effectiveness. This poses a significant safety hazard to on-site workers, rendering personal protective measures ineffective and creating a serious safety situation. Therefore, to ensure personal safety, relevant standards stipulate that the grounding pin should be inserted at a depth of at least 60 cm.

[0003] The depth markings on the existing grounding pins are made by paint and groove filling paint. In actual use, the paint markings are easy to fall off, and the groove filling paint markings are easily obscured by dirt and cannot be distinguished. Users may also operate improperly, resulting in the insertion depth of the grounding pin not meeting the requirements. In addition, the existing grounding pin grounding detection device is battery-driven, and it will fail when the battery is exhausted, and there is a risk that the hooking status cannot be detected. Utility Model Content

[0004] The purpose of the utility model is to provide a grounding pin grounding sensor for a grounding device that ensures that the grounding pin is inserted into the ground to a fixed depth while avoiding the risk of being unable to detect due to power exhaustion, enhancing the reliability of grounding detection, and effectively improving safety.

[0005] The utility model is achieved in this way:

[0006] A grounding pin grounding sensor of a grounding device comprises a shell fixedly connected to the grounding pin, a self-generating module installed in the shell, the self-generating module electrically connected to a radio frequency transmitting module, a top column movably arranged in the shell, the top column being arranged opposite to the spring piece of the self-generating module, and the grounding pin being movably connected to a push plate for pushing the top column.

[0007] Furthermore, the shell includes an upper shell and a lower shell, the upper shell is fixedly connected to the lower shell, the top column, the self-generating module and the radio frequency transmitting module are arranged between the upper shell and the lower shell, the lower shell is fixedly connected with a ring, the lower shell is provided with a pin groove, the pin groove is arranged perpendicular to the ring, and passes through the lower shell and the ring.

[0008] Furthermore, one end of the top column abuts against the spring sheet of the self-generating module, and the other end of the top column passes through the shell and protrudes from the outer surface of the shell.

[0009] Furthermore, the push plate is movably sleeved on the grounding pin, and a plurality of guide posts are fixedly connected to the push plate. The plurality of guide posts are arranged around the grounding pin, and the shell is provided with guide holes matching the guide posts.

[0010] Furthermore, the number of the guide posts is four, and the four guide posts are evenly spaced and arranged around the grounding pin, and the number of the guide holes matches the number of the guide posts.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] In actual application, the shell is fixedly connected to the grounding pin and is set at a position greater than the standard grounding height of the grounding pin. The grounding pin is inserted into the ground, and the push plate is pushed close to the shell through the ground, and the top column is squeezed to move upward. The top column pushes the spring that presses the self-generating module to move forward, and the spring drives the magnetic head of the self-generating module to move. The magnetic flux lines cut the fixed coil of the self-generating module in the positive direction, and the fixed coil generates a positive induced current. The positive induced current drives the radio frequency transmitting module to send a radio frequency signal to the receiving end to remind the staff that the grounding pin is inserted into the required depth underground; if the grounding pin becomes loose, the torsion spring in the self-generating module pushes the spring to move in the opposite direction, and the spring drives the magnetic head of the self-generating module to move, and the magnetic flux lines cut the self-generating module in the opposite direction. The fixed coil of the electrical module generates a reverse induced current, and the reverse induced current drives the RF transmitting module to send an RF signal to the receiving end to remind the staff that the grounding pin has become loose; the RF transmitting module and the self-generating module are both existing technologies and can be purchased, connected and installed; while ensuring that the grounding pin is inserted into the ground to a fixed depth, no battery or external power supply is required during the grounding detection process, avoiding the risk of power exhaustion and inability to detect, enhancing the reliability of grounding detection, and effectively improving safety; the present application avoids the risk of power exhaustion and inability to detect while ensuring that the grounding pin is inserted into the ground to a fixed depth, enhancing the reliability of grounding detection, and effectively improving safety.
