Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
Referring to Fig. 1, a kind of simple and easy automatic earthing electric discharge device, include support 1, on support 1, be installed with electromagnet 2, on support 1, below electromagnet 2, be provided with pilot hole and by the upper connecting rod 3 that has been slidably installed, the end of upper connecting rod 3 is fixedly connected with the contact 4 matching with electromagnet 2 contacts, on support 1, below upper connecting rod 3, be installed with hinged seat 5, on hinged seat 5, be hinged with connecting rod 6, the front end of connecting rod 6 is hinged with lower link 7, and the bottom of upper connecting rod 3 is hinged on connecting rod 6; The bottom of lower link 7 is fixedly connected with contact 8, and the bottom of support 1 is installed with the lower contact 9 matching with upper contact head 8, and upper and lower contact 8,9 is electrically connected to power equipment and the earth respectively.
In the utility model, support 1 is assemblied to form by epoxy plate; Upper and lower contact 8,9 is respectively copper sheet.
Below in conjunction with accompanying drawing, the utility model is further described:
The external 220V power supply of electromagnet 2 or 380V power supply, by switch, control its folding, after electromagnet 2 energisings, contact 4 adhesives of electromagnet 2 contacts and upper connecting rod 3 ends, upper connecting rod 3 can move up in stressed effect, by connecting rod 6, drive lower link 7 to promote, thereby realize upper and lower contact 8,9 separation, reach the object that power equipment is not connected with the earth.
When power equipment need to discharge over the ground, disconnect electromagnet 2 power supplys, electromagnet 2 contacts are separated with the contact 4 of upper connecting rod 3 ends, the effect of upper connecting rod 3 meeting gravity moves down, by connecting rod 6, drive lower link 7 to decline, upper and lower contact 8,9 contacts, realize power equipment and are connected with the earth, make conduct current the earth, realize automatic discharging function.
