[0030] There are two rollers; the signal line 6 passes through the rollers in sequence in an S-shaped distribution. A roller is provided at the tail of each insulating rod, and two rollers are provided. The signal line 6 passes through one end of the first roller 7 and passes through one end of the second roller 5 in an S-shaped manner, thereby realizing the retraction and release of the signal line 6 when the telescopic insulating rod 3 is extended and stretched.

[0031] The central axis direction of the roller and the length direction of the telescopic insulating rod 3 are arranged perpendicular to each other.

[0032] The telescopic insulating rod 3 is coated with epoxy resin inside and outside; it is composed of several sections of insulating rods, and each two sections of insulating rods are fixed by convex locking beads; a small section of annular metal conductor with the same diameter as the insulating rod is provided on the first section of the insulating rod, and a resistance-discharge connection hole 31 is provided on the annular metal conductor for connecting a discharge wire plug 10 or a discharge wire clamp 11; a discharge metal hook 1 is provided on the top of the telescopic insulating rod 3, and a discharge current limiting resistor is connected between the discharge metal hook 1 and the annular metal conductor, and the discharge current limiting resistor is located inside the insulating rod.

[0033] The discharge metal hook 1 and the inductive sensor 2 are located at the top of the insulating rod, and the distance between the intersection of the arc and the straight shape of the discharge metal hook 1 and the inductive capacitive sensor is the safety distance specified by the regulations.

[0034] The rubber insulating handle 9 has concave-convex textures to increase the roughness of the contact surface, thereby increasing friction and preventing it from falling off; there is a guard ring on the insulating handle, and when using the grounding rod, the hand must not exceed the guard ring of the handle part.

[0035] The inductive sensor 2 is composed of a sensing element, a conversion element and a signal conditioning and amplification circuit. The sensing element is composed of two parallel metal plates.

The electrical signal output by the inductive sensor 2 is converted into a digital signal by the analog-to-digital converter in the MCU module. The controller in the MCU module analyzes and processes the digital signal, controls the charged indicator light in the audio-visual linkage alarm module to flash and the charged alarm to sound, thereby prompting the staff that the discharge device has not been fully discharged and needs to continue discharging.

[0039] The technical solution is simple and reliable, and the production cost is low. The signal is transmitted through the signal line 6, and the transmission effect is more stable. The signal line 6 passes through the first roller 7 and the second roller 5 in sequence, which increases the stability of the signal line 6 when it is placed inside the telescopic rod, and realizes the retraction and extension of the signal line when the telescopic rod is extended and stretched. It effectively avoids the problem of mistransmission caused by unstable signal transmission in the prior art.
