Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grounding equipment, in particular to a grounding device hook external hooking 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 external 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 external hook sensor includes a shell fixedly connected to the grounding hook, the shell is movably connected to a slider, the slider is connected to a connecting rod, the connecting rod is rotatably connected to the shell, one end of the connecting rod is connected to a self-generating module, the self-generating module is electrically connected to a radio frequency transmitting module, and the spring of the self-generating module is connected to the connecting rod.
[0008] Furthermore, the spring of the self-generating module is in contact with a spring on a side away from the connecting rod.
[0009] Furthermore, the RF transmitting module and the self-generating module are both installed inside the shell, and a plurality of limiting brackets for limiting and fixing the connecting rod, the RF transmitting module and the self-generating module are fixedly connected inside the shell.
[0010] Furthermore, the slider is in an I-shape, and a guide rail is fixedly connected to one side of the slider connected to the shell, and a guide groove is provided in the shell corresponding to the guide rail.
[0011] Furthermore, the shell is fixedly connected to the side of the grounding hook, and the shape of the shell matches the shape of the grounding hook.
[0012] Furthermore, a water leakage hole is provided on the shell.
[0013] Compared with the prior art, the beneficial effects of the present invention are:
[0014] In actual application, the grounding clamp is clamped on the grounding conductor. When the opening of the grounding clamp is tightened, the grounding conductor pushes the slider to move, and the slider pushes the spring that presses the self-generating module to move forward. 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 grounding clamp is stably connected to the grounding conductor. If the connection between the grounding clamp and the grounding conductor becomes loose or falls off, the slider loses the pushing force of the grounding conductor, and the torsion spring in the self-generating module pushes 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 Reverse induced current, the reverse induced current drives the RF transmitting module to send a RF signal to the receiving end to remind the staff that the connection between the grounding clamp and the grounding conductor is loose or detached; the slider squeezes or releases the spring of the self-generating module, thereby generating a forward or reverse induced current to distinguish whether the grounding clamp and the grounding conductor are stably connected, and drives the RF transmitting module to send a signal through the forward or reverse induced current 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, avoiding the risk of power exhaustion and inability to detect, enhancing the reliability of grounding detection, and effectively improving safety; this application avoids the risk of power exhaustion and inability to detect, enhances the reliability of grounding detection, and effectively improves safety.

[0023] In actual application, the grounding hook 1 is hung on the wire, and the wire pushes the slider 3 to move upward, and the slider 3 pushes one end of the connecting rod 4 to lift and rotate, so that the other end of the connecting rod 4 presses the spring 7 of the self-generating module 5 to move forward, and the spring 7 drives the magnetic head of the self-generating module 5 to move, and the magnetic flux lines cut the fixed coil of the self-generating module 5 in the positive direction, and the fixed coil generates a positive induced current. The positive induced current drives the radio frequency transmitting module 6 to send a radio frequency signal to the receiving end to remind the staff that the grounding hook 1 is stably connected to the wire; if the grounding hook 1 is separated from the wire, the slider 3 loses the pushing force of the wire, and the torsion spring in the self-generating module 5 pushes the spring 7 to move in the opposite direction, and pushes the slider 3 to reset through the connecting rod 4. At the same time, the spring 7 drives the magnetic head of the self-generating module 5 to move, and the magnetic flux lines cut the fixed coil of the self-generating module 5 in the opposite direction, and the fixed coil generates a reverse induced current. The RF transmitting module 6 is driven by the current to send a RF signal to the receiving end to remind the staff that the connection between the grounding hook 1 and the wire is loose or detached; the RF transmitting module 6 and the self-generating module 5 are both existing technologies and can be purchased, connected and installed; the slider 3 drives the connecting rod 4 to squeeze or loosen the spring 7 of the self-generating module 5, thereby generating a forward or reverse induced current to distinguish whether the grounding hook 1 is stably connected to the wire, and drives the RF transmitting module 6 to send a signal through the forward or reverse induced current to remind the staff to pay attention to construction safety; in the process of grounding detection of the grounding hook 1, 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.
[0024] See also Figure 1 The spring 8 abuts against the side of the spring piece 7 of the self-generating module 5 away from the connecting rod 4 .
[0025] In this embodiment, a spring 8 is provided on one side of the spring piece 7 of the self-generating module 5, and the spring 8 is provided on the side away from the connecting rod 4. When the connecting rod 4 presses the spring piece 7 of the self-generating module 5 driven by the slider 3, the spring 8 is deformed under the pressing action of the spring piece 7. When the slider 3 loses the force of the wire, the spring 8 recovers its deformation, assisting the torsion spring inside the self-generating module 5 to push the spring piece 7 to move in the opposite direction, thereby enhancing the rebound sensitivity of the spring piece 7 of the self-generating module 5.
[0026] See also Figure 1 and Figure 3 The RF transmitting module 6 and the self-generating module 5 are both installed inside the shell 2, and a plurality of limiting supports 9 are fixedly connected inside the shell 2 for limiting and fixing the connecting rod 4, the RF transmitting module 6 and the self-generating module 5.

The limiting support 9 is fixedly connected to the shell 2, and plays a limiting and fixing role on the connecting rod 4, the radio frequency transmitting module 6 and the self-generating module 5. In the process of the connecting rod 4 rotating and pressing the spring 7 of the self-generating module 5, the connecting rod 4 is prevented from moving in the vertical direction, and the radio frequency transmitting module 6 and the self-generating module 5 are prevented from moving, thereby effectively improving the reliability and stability of the detection.
[0028] See also Figure 1 and Figure 4 The slider 3 is in an I-shape, and a guide rail 10 is fixedly connected to one side of the slider 3 connected to the housing 2 . The housing 2 is provided with a guide groove 11 corresponding to the guide rail 10 .
[0029] In this embodiment, the slider 3 is in the shape of an "I" character, and the two transverse parts of the slider 3 are used to limit the upper and lower movement limits of the slider 3 to prevent the slider 3 from separating from the housing 2. The slider 3 slides under the limiting action of the guide groove 11 through the guide rail 10, effectively enhancing the stability of the movement of the slider 3.
[0030] See also Figure 2 The shell 2 is fixedly connected to the side of the grounding hook 1 , and the shape of the shell 2 matches the shape of the grounding hook 1 .
[0031] In this embodiment, the shell 2 is arranged on the side of the grounding hook 1, and the shape of the shell 2 matches the shape of the grounding hook 1 to avoid a top protruding structure, thereby avoiding damage caused by accidental bumps.
[0032] See also Figure 3 A water leakage hole 12 is provided on the shell 2.
[0033] In this embodiment, since the housing 2 is in an unsealed state and there is a risk of water seepage, a water leakage hole 12 is opened on the housing 2 to prevent water from accumulating in the housing 2 .
