Abstract
A novel portable ground protection device belongs to the technical field of protection and aims to solve the problem of personal safety of a mobile (hand-held) electrical device operator. The novel portable ground protection device is implemented as follows: the device comprises a grounding electrode, a control switch and a ground wire connecting column; the grounding electrode is composed of a grounding electrode striking body, a thin-wall hollow grounding body and a tapered ground drill; the grounding electrode striking body is cone-shaped and forms the grounding electrode with the tapered ground drill after being welded with the thin-wall hollow grounding body; the control switch is composed of a position-switch mechanical striker, a position-switch movable contact, a position-switch fixed contact, a return spring and a control signal wire; and the ground wire connecting column is composed of a ground wire bolt and a disc nut. Before using the mobile (hand-held) electrical device, the housing ground wire of the mobile (hand-held) electrical device with a nut is inserted into the ground wire bolt and then the disc nut is screwed down to guarantee reliable connection of the housing ground wire of the mobile (hand-held) electrical device and the grounding body. The novel portable ground protection device is simple in structure and low in cost.
Description
Technical field
The chassics earth protection field of the utility model relates to mobile (handing) formula electric equipment; Be exactly a kind ofly to consider specifically from the safety utilization of electric power angle; Require to use the operator who moves (handing) formula electric equipment, must guarantee that before use casing by the spendable a kind of earth protective device in electricity consumption code requirement ground connection rear, uses this device can protect operator's personal safety; Avoid the equipment casing charged and personnel's electric shock accidents of taking place belongs to the resist technology field.
Background technology
Along with the develop rapidly of electronics, electric science and technology, people use various (handing) formula electric equipments that move more and more in daily production, life.But in using these device procedures, receive reasons such as its electric part ageing of insulation, line voltage sudden change, electronic devices and components fault, operate miss; Cause electric insulation puncture, short trouble generation easily and then cause that such device housings is charged, cause the generation of operating personnel's electric shock accidents.For preventing to move the injury that the body leakage of (handing) formula electric equipment causes the person, most of electric equipments (electric equipment that especially has metal shell) all are provided with earth terminal, and require and must can use behind the reliable ground.Yet in reality was used these electric equipment processes, the operator is off one's guard to be forgotten ground connection or entertains idea of leaving things to chance and think that casing can not leak electricity, and uses under the situation that does not connect earth connection.Therefore exist potential safety hazard.Before the utility model design is accomplished, do not see with the utility model structure, portable earth protective device that function is identical and in actual production, life, use, do not see with the utility model structure, device that function is identical yet and sell.
Summary of the invention
The purpose of the utility model is to overcome the deficiency of prior art; Provide a kind of (handing) formula electric equipment shell that moves maybe cannot not be abutted against under the situation on ground unearthed; Also can't get electric normal operation even if connect the power devices power-supply device, and then a kind of electric equipment earth protective device that the user is protected.
For achieving the above object, the utility model has adopted following technical scheme:
A kind of novel portable earth protective device; Comprise earth electrode, control switch and earth connection joint pin; Said earth electrode is beaten body, thin-walled hollow earth electrode and the tapered bur edge of a field by earth electrode and is formed; After earth electrode is beaten body (zinc-plated carbon steel) and is taper type and thin-walled hollow earth electrode (zinc-plated carbon steel) and is welded, connect to form earth electrode with the tapered bur edge of a field again; Said control switch is made up of position switch machinery striker, position switch moving contact, position switch fixed contact, back-moving spring and control signal wire; When earth electrode was driven underground more than 60 centimetres, position switch machinery striker was extruded stressed, and back-moving spring shrinks; The position switch moving contact contacts with the position switch fixed contact; Accomplish the closure of switch, the electric control loop that control signal wire is communicated with controlled device forms complete closed-loop path, and controlled device gets the electric service conditions that possesses; Said earth connection joint pin is made up of earth connection bolt and wing nut; After before using mobile (handing) formula electric equipment, will inserting earth stud with the earthing of casing line of nut earlier, again wing nut is screwed to guarantee that moving (handing) formula electric equipment earthing of casing line reliably is connected with earth electrode.Finally realized moving (hand) formula electric equipment shell unearthed or press under the situation of electricity consumption code requirement ground connection through closely cooperating of above each several part; Power consumption equipment power supply control loop can't get electric normal operation, and then has guaranteed the personal safety of equipment user.
The utility model has more following effects and good effect:
When a kind of novel portable earth protective device utilizes earth electrode to be driven underground more than 60 centimetres; Position switch machinery striker is extruded stressed; Back-moving spring shrinks, and the position switch moving contact contacts with the position switch fixed contact, accomplishes the closure of switch; The electric control loop formation closed-loop path controlled device of control signal wire connection controlled device gets electric, possesses service conditions.Can guarantee that through using this device shell is unearthed or press under the situation of electricity consumption code requirement ground connection when use moving (hand) formula electric equipment; Also can't get electric normal operation even if connect the power devices power-supply device, and then protection operator personal safety.The utlity model has simple in structure, cost is low, uses reliable and securely, makes the use of power consumption equipment accomplish the equipment Essential Safety, so good obvious social benefit of promotion prospect.
