Abstract

The utility model relates to an electric pre-alarming grounding wire operating rod. The operating rod consists of a conducting wire clip, an electromagnetic induction wire, an alarming horn, an electric induction chip, a battery, a self-testing button and a grounding wire operating rod. One section of grounding wire operating rod outer casing is half dug from the grounding wire operating rod. One circuit board provided with the alarming horn, the electric induction chip, the battery and the self-testing button is embedded in the outer casing. A power supply circuit of the electric induction chip is connected with the battery. An output circuit of the electric induction chip is connected with the alarming horn in series, and is connected with the self-testing button in parallel. An input circuit of the electric induction chip is connected with the induction wire. The induction wire is fixed on both sides of the conducting wire clip. The self-testing button is embedded on the surface of the outer casing. The outer casing is connected with a screw of the grounding wire operating rod, or the circuit board is embedded in the lower end of the grounding wire operating rod. The self-testing button is arranged on the surface of the grounding wire operating rod which is arranged on a handle sheath, and the alarming horn is arranged on a tail cover of the grounding wire operating rod. The tail cover is provided with a voice through hole.

Description

Electric pre-alarm earth connection hook stick is arranged

One, technical field

The utility model relates to the electric pre-alarm earth connection hook stick that has that a kind of electrician uses, and prevents the problem that the electrician gets an electric shock when solving our wiring of maintenance electricity.

Two, background technology

When the electrician needs to carry out work on electric equipment, must carry out short circuit ground connection at two ends, electric equipment working region, carry out technical safety measures, the electric operation personnel following misoperation may occur in carrying out the grid switching operation process: 1, may the error checking position during electrical verification in the grid switching operation; When 2, in the grid switching operation short-circuit grounding wire being installed wrong position may be installed; 3, after electric equipment has been tested electricity in the grid switching operation, before being installed, short-circuit grounding wire may send a telegram here; 4, the selection of electroscope electric pressure is improper, and electroscope directly contacts electric equipment to a some position, when the electric equipment residual voltage is lower than galvanoscopic alarm voltage, short-circuit grounding wire is installed is still had the electric shock possibility; Based on some misoperation in the above execution banister operation, abnormally dangerous with the electric personnel of periphery to the electric operation personnel that short-circuit grounding wire is installed, the high voltage electric field that the short-circuit grounding wire installation is produced can hit the people dead or wound.

Three, summary of the invention

The purpose of this utility model provides a kind of electric pre-alarm earth connection hook stick that has, and solves the casualty accident that persistent ground wire that above-mentioned prior art exists causes.

The technical solution of the utility model realizes in the following manner:

The utility model is by wire clamp, electromagnetic induction line, alarming horn, electric induction chip, battery, self check button and earth connection hook stick are formed, on the earth connection hook stick, half-and-half dig up an earth connection hook stick shell, inlay a circuit board that is provided with alarming horn, electric induction chip, battery and self check button in the enclosure; Electric induction chip power circuit and battery link, and the output circuit of electric induction chip is connected with alarming horn, and be in parallel with the self check button, and the electric induction chip input circuit and the line of induction link; The line of induction is fixed on the wire clamp both sides, and the self check button is embedded in the appearance of shell; Shell links to each other with earth connection hook stick screw, or circuit board is embedded in inside, earth connection hook stick lower end, the self check button is installed in the surface of handle sheath top earth connection hook stick, and alarming horn is installed on the tail-hood of earth connection hook stick, and tail-hood is provided with continuant orifice.

Compared with the prior art the utility model has following advantage:

1, in time sense the signal of telecommunication that has of repair circuit by the electric induction chip, and report to the police by alarming horn, the caution operator does not want misoperation, has prevented the generation of electric shock casualty accident.

2, circuit board is inlayed on the shell of diging up, and shell links to each other with earth connection hook stick screw, or is installed in hook stick tail end inside, and the operation maintenance is convenient.

3, strong interference immunity, mounting points are not disturbed by contiguous electric equipment, not influenced by vision, weather and geographical environment.

Five, embodiment:

For further disclosing the technical solution of the utility model, elaborate by embodiment below in conjunction with Figure of description:

The utility model is by wire clamp 1, electromagnetic induction line 2, alarming horn 5, electric induction chip 3, battery, self check button 4 and earth connection hook stick 6 are formed, on the earth connection hook stick, half-and-half dig up an earth connection hook stick shell, inlay a circuit board that is provided with alarming horn, electric induction chip, battery and self check button in the enclosure; Electric induction chip power circuit and battery link, and the output circuit of electric induction chip is connected with alarming horn, and be in parallel with the self check button, and the electric induction chip input circuit and the line of induction link; The line of induction is fixed on the wire clamp both sides, and the self check button is embedded in the appearance of shell; Shell links to each other with earth connection hook stick screw, or circuit board is embedded in inside, earth connection hook stick lower end, the self check button is installed in the surface of handle sheath top earth connection hook stick, and alarming horn is installed on the tail-hood of earth connection hook stick, and tail-hood is provided with continuant orifice.

When using the utility model, by self check button 4, alarming horn 5 sends sound earlier, illustrate that circuit part is normal, hand-held earth connection hook stick 6, ground clamp be held in wire clamp 1 on, lead can not slip out, and is lifting ground wire with the earth connection hook stick and is being connected on the electric wire that has cut off the power supply; During near electric wire, electric induced line 2 has received the signal of telecommunication as wire clamp, passes to alarming horn 5 through electric induction chip 3 and sends alert sound, illustrate that electric wire has the electricity can not earth connection, has found out electric reason, earth connection again when definite electric wire does not have electricity.
