Abstract
A foldable low-voltage discharging rod comprises an insulation operating rod, wherein the insulation operating rod comprises a grab handle and a foldable handle which are hinged and connected; a discharging conductor is fixedly connected to the free end of the foldable handle, and is electrically connected with a ground wire; the two ends of the ground wire are fixedly connected with retaining clips; one of the retaining clips is connected with the discharging conductor; a groove is formed in the grab handle, and the opening of the groove faces to one side of the grab handle; after the foldable handle is folded, the discharging conductor is positioned in the groove; the grab handle and the foldable handle are hinged and connected through a connecting bolt; the discharging conductor is pressed and limited at the free end of the foldable handle through a positioning bolt. According to the invention, through the reference of the principle of a high-voltage discharging rod, the low-voltage discharging rod with the foldable structure is manufactured, so that an operator can keep a certain safe distance away from the positions likely to be charged; the insulation operating rod comprises the grab handle section and the foldable handle section which are mutually hinged, the discharging conductor is mounted at the front end of the foldable handle positioned at the front end of the insulation operating rod, and the discharging conductor is connected with the ground wire through one of the retaining clips, so that ground discharge is realized, the use is safe, and the operation is convenient.
Description
Technical field
The present invention relates to a kind of mining device, relate in particular to a kind of folding low-voltage discharging rod.
Background technology
When all kinds of electric equipments are carried out to repair and maintenance operation, requisite management and control flow process when " power failure, electrical verification, electric discharge, installing earth connection, suspension warning sign " becomes Electrician Operation, according to " safety regulations in coal mine " the 445 regulation, " before maintenance or resettlement; must cut off the electricity supply; check gas, in its air flow in laneway, gas density lower than 1.0% time, then is used the electroscope check adapting with supply voltage; Check without electricity after, can carry out ground conductor discharge." " electric industry safety engineering rules " also carried out relevant regulations to electric discharge work, " measuring before and after insulation, tested device must be discharged over the ground.”
In underground work, when the above high voltage electric equipment of 1140V is overhauled, staff can use corresponding high-voltage discharging rod to discharge.But when the following low voltage electrical equipment of 1140V is overhauled, because of the low pressure discharge rod not adapting at present, be therefore inconvenient to discharge, if use high-voltage discharging rod, owing to portably using inconvenience, be therefore seldom used.In real work, staff generally, after carrying out electrical verification, directly uses wire or electrician's instrument to discharge over the ground, and this wherein certainly will produce the Risk factors that causes personal injury.
Summary of the invention
The object of this invention is to provide a kind of folding low-voltage discharging rod safe and convenient to use, use of the present invention can ensure aboveground lower electric operation personnel's personal safety, and standard electric discharge standard, reaches the object of effectively repair apparatus being discharged.
For achieving the above object, the technical solution used in the present invention is:
A kind of folding low-voltage discharging rod, comprise insulating bar, insulating bar comprises lever and the foldable handle being hinged and connected, it is characterized in that: foldable handle free end is fixedly connected with electric discharge conductor, electric discharge conductor is electrically connected with earth connection, earth connection two ends are fixedly connected with geometrical clamp, and one of them geometrical clamp is connected with electric discharge conductor.
Folding low-voltage discharging rod according to described, is characterized in that: described lever has groove, and the opening of groove is towards a side, and after described foldable handle is folding, described electric discharge conductor is positioned at groove.
Folding low-voltage discharging rod according to described, is characterized in that: described lever and described foldable handle are hinged and connected by connecting bolt.
Folding low-voltage discharging rod according to described, is characterized in that: it is spacing at described foldable handle free end that described electric discharge conductor dbus is crossed bolt crimping.
The present invention uses for reference the principle of high-voltage discharging rod, has been made into accordion structure, adopts insulating material to make the insulating bar of discharging rod, makes the position that operating personnel can be charged with possibility keep certain safe distance; Insulating bar comprises two sections of mutually hinged lever and foldable handles, and the foldable handle front end that is positioned at front end is equipped with one section of electric discharge conductor, connects earth connection, thereby realize the object of discharging over the ground on electric discharge conductor by geometrical clamp, uses safe, easy to operate.Because lever and foldable handle are hinged and connected, therefore, when not using, this discharging rod can fold, to facilitate staff to carry.

Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described:
A kind of folding low-voltage discharging rod, as shown in Figures 1 to 8, comprise insulating bar, insulating bar comprises lever 1 and the foldable handle 4 being hinged and connected, foldable handle 4 free ends are fixedly connected with electric discharge conductor 6, electric discharge conductor 6 is electrically connected with earth connection 8, and earth connection 8 two ends are fixedly connected with geometrical clamp 7, and one of them geometrical clamp 7 is connected with electric discharge conductor 6.
In the present embodiment, described lever 1 has groove 2, and the opening of groove 2 is towards a side, and after described foldable handle 4 is folding, described electric discharge conductor 6 is positioned at groove 2.Described lever 1 is hinged and connected by connecting bolt 3 with described foldable handle 4.Described electric discharge conductor 6 is spacing at described foldable handle 4 free ends by bolt 5 crimping.
Embodiment recited above is described the preferred embodiment of the present invention; not the spirit and scope of the present invention are limited; do not departing under the prerequisite of design concept of the present invention; various modification and improvement that in this area, common engineers and technicians make technical scheme of the present invention; all should fall into protection scope of the present invention; the technology contents that the present invention asks for protection, is all documented in claims.
