Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grounding equipment, in particular to a grounding device hook embedded hook sensor. Background Art
[0002] When inspecting high-voltage power lines, the normal procedure is to first disconnect the power to the line being inspected. The operator then attaches a grounding hook to the line being inspected. If high-voltage power is accidentally transmitted, the grounding rod attached to the device will conduct the high-voltage power underground, preventing any injuries.
[0003] To ensure worker safety, it's crucial to constantly monitor the connection status between the power lines and the grounding equipment to ensure its stability. If the connection becomes loose or disconnected, the grounding equipment becomes ineffective, leaving workers unprotected and threatening their safety. Therefore, equipment is needed to monitor the stability of the connection between the grounding clamp and the grounding conductor to ensure worker safety.
[0004] However, existing detection equipment is battery-driven and becomes ineffective when the battery is exhausted, resulting in the risk of being unable to detect the connection status. Utility Model Content
[0005] The purpose of the utility model is to provide a grounding device hook embedded hook sensor which avoids the risk of being unable to detect due to power exhaustion, enhances the reliability of grounding detection, and effectively improves safety.
[0006] The utility model is achieved in this way:
[0007] A grounding device hook embedded hanging sensor includes a hook body for hanging with a wire and a pressing plate with one end rotatably connected to the hook body, one end of the pressing plate is fixedly connected to a connecting rod, the end of the connecting rod away from the pressing plate is connected to a self-generating module, the spring piece of the self-generating module is connected to the connecting rod, and the self-generating module is electrically connected to a radio frequency transmitting module.
[0008] Furthermore, the self-generating module and the radio frequency transmitting module are both fixedly embedded in the hook body.
[0009] Furthermore, a plurality of position limiting supports for limiting the position of the self-generating module and the radio frequency transmitting module are fixedly connected in the hook body.
[0010] Compared with the prior art, the beneficial effects of the present invention are:
[0011] In actual application, the hook body is hung on the wire. During the process of hanging the hook body and the wire, the wire squeezes and pushes the pressure pieces on both sides. One end of the pressure piece connected to the self-generating module drives the connecting rod to press the spring of the self-generating module. The spring drives the magnetic head of the self-generating module to move, and the magnetic flux lines cut the fixed coil of the self-generating module in the positive direction. The fixed coil generates a positive induced current. The positive induced current drives the RF transmitting module to send a RF signal to the receiving end to remind the staff that the hook body is stably connected to the wire. If the connection between the hook body and the wire becomes loose or falls off, the pressure piece will lose force, and the torsion spring in the self-generating module will push the spring to move in the opposite direction. The spring drives the magnetic head of the self-generating module to move, and the magnetic flux lines cut the fixed coil of the self-generating module in the opposite direction. The fixed coil generates a reverse induced current, and the reverse induced current drives the RF The sending module sends a radio frequency signal to the receiving end to remind the staff that the connection between the hook and the wire is loose or detached; among them, the self-generating module and the radio frequency sending module belong to the existing technology and can be purchased, connected and installed; the spring of the self-generating module is driven to move by whether the pressing piece is under force, thereby generating a forward or reverse induced current to distinguish whether the hook and the wire are stably connected, and the radio frequency sending module is driven by the forward or reverse induced current to send a signal to remind the staff to pay attention to construction safety; in the process of grounding detection of the grounding clamp, no battery or external power supply is required, which avoids the risk of being unable to detect due to exhaustion of power, enhances the reliability of grounding detection, and effectively improves safety; this application avoids the risk of being unable to detect due to exhaustion of power, enhances the reliability of grounding detection, and effectively improves safety.
