Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage grounding rod early warning devices, in particular to a near-electricity-proof touch-proof high-voltage grounding rod early warning device. Background Art

[0002] When workers inspecting power lines and equipment climb poles to install and connect wires, they face varying degrees of difficulty and unpredictable factors in complex environments, leading to potential safety risks. These risks include accidentally climbing a live line tower, not maintaining a safe distance from adjacent live lines, and potential reverse power supply from self-contained power supplies. Failure to promptly determine safe distances can lead to close proximity to high-voltage power, potentially causing accidents.

[0003] For example, the patent document with application number CN202022444876.9 discloses a high-voltage grounding rod warning device for preventing touching due to proximity to electricity. When using this utility model, the other end of the grounding wire is first grounded. The operator turns on the proximity mechanism, and then holds the insulating ring. When there is no voltage, the hook part of the buckle can be overlapped on the line when in use. When the proximity mechanism sounds an alarm, the operator is reminded to pay attention to safety. However, the high-voltage grounding rod warning device for preventing touching due to proximity to electricity is prone to shaking or falling off due to external wind during use, affecting the normal use of the device.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a near-electric anti-touch high-voltage grounding rod early warning device is proposed. Utility Model Content

[0012] Preferably, the front end of the winding drum is electrically connected to a grounding wire, and the end of the grounding wire is connected to a plug rod.

[0013] Compared with the prior art, the beneficial effect of the present invention is that the near-electricity anti-touch high-voltage grounding rod warning device can not only prevent the device from falling off during use, but also can reel in the grounding wire to reduce occupied space.

[0014] 1. The utility model adopts the setting of the anti-drop assembly, so that the spring pushes the pull rod downward, and the pull rod drives the rack to move synchronously, and then drives the rack to push the gear to rotate in the opposite direction.

The end of the pull rod 304 away from the spring 305 is fixedly installed with an insulating handle 306, and the pull rod 304 is slidably connected to the hollow tube 1.

[0023] The spring 305 pushes the pull rod 304 downward, and the pull rod 304 drives the rack 303 to move synchronously, and then drives the gear 302 to rotate in the opposite direction by driving the rack 303. While the gear 302 rotates, it controls the guard plate 301 to dock with the hook 2, and forms a closed loop with the hook 2 to prevent it from falling off.

[0024] Furthermore, the left end of the guard plate 301 is rotatably connected to the hook 2, and the guard plate 301 is arranged in an arc-shaped structure as a whole.

[0025] like Figure 3-Figure 4 As shown, the left end of the guard plate 301 is rotatably connected to the hook 2, and the guard plate 301 is arranged in an arc-shaped structure as a whole.

[0026] Furthermore, a clamping plate 4 is provided on the left outer wall of the hollow tube 1, and the clamping plate 4 is provided in a "C"-shaped structure.

[0027] The hollow tube 1 facilitates sliding connection of the pull rod 304 disposed inside.

It features time counting and a contactless audible alarm when it senses an electric field. If a user wearing the watch-type near-electricity alarm 6 mistakenly enters a live area or climbs a live pole, the alarm will immediately emit a continuous audible alarm signal, alerting the operator to the danger and preventing electric shock injuries and fatalities caused by misconceptions and errors.

[0037] Example 2: When in use, the electricity in the hollow tube 1 is guided into the interior of the proximity alarm 6 through the spring conductive column 5, and then the electricity of the proximity alarm 6 is introduced into the grounding wire 11 through the conductive copper tube 8 and guided to the ground. When not in use, the winding drum 10 is driven to rotate clockwise by the torsion spring shaft 7, and the grounding wire 11 electrically connected to the outer wall of the winding drum 10 is wound and pulled back to the bottom of the proximity alarm 6, reducing the space occupied by the line when not in use. This is the working principle of the proximity anti-touch high-voltage grounding rod warning device.
