Embodiment Construction

[0015] The present invention is described in detail below in conjunction with accompanying drawing:

[0016] see figure 1 and figure 2 As shown, a mobile multifunctional external grounding device of the present invention includes a grounding panel 1 , a supporting pillar 2 , a grounding pin 5 , a screw 6 , a ferrule 9 , a nut 10 and a wrench 11 .

[0017] The top of the grounding needle 5 is fixed on the screw mandrel 6, and the screw mandrel 6 is provided with a pedal rod 61. When in use, connect the lead screw 6 to the grounding pin 5, step on the pedal rod 61 to make the grounding pin 5 drill into the specified point on the ground (80 cm, if it cannot reach this size, you can use the lead screw to rotate to reach this size) After the grounding needle 5 is basically fixed firmly, install the grounding panel 1 and the upper and lower hoops 9 on the grounding panel 1 and fix them to fix the nut on the screw rod 6 between the upper and lower hoops 9, and at the same time fix...

Abstract

The invention provides a movable multifunctional external grounding device, which comprises a grounding panel, a grounding pin, a lead screw, a nut, an upper ferrule and a lower ferrule, wherein the top of the grounding pin is fixed on the lead screw; a pedal rod is arranged on the lead screw; the nut is sleeved at the periphery of the lead screw, forms a pair of lead screw nut mechanism with the lead screw and is fixed on the grounding panel; the nut is fixed on the grounding panel through the upper ferrule and the lower ferrule; a water inlet pipeline is arranged on the lead screw; the tail end of the water inlet pipeline is provided with a drainage groove; and the top of the lead screw is provided with an inner hexagon spanner. The movable multifunctional external grounding device is suitable for assembly of substations and output line iron towers and is mainly used for providing shell grounding measures of large equipment with an external power supply and temporary grounding measures in line construction. The device is mainly used for preventing thunderstorm and thunder from damaging the shells of tools and harming personal safety of workers, the thunder can be drained reliably under the ground during raining and lightning, and the workers and the equipment are safe in operation and are protected.

Description

technical field [0001] The invention belongs to the field of electric power, in particular to a grounding device. Background technique [0002] With the work requirements of power grid, power equipment, distribution network lines, transmission lines and other large and medium-sized power equipment and line inspection and maintenance, the working area of ​​many equipment is relatively far away from the main ground terminal under the power structure, making the inspection and maintenance work easier. The personal safety of personnel cannot be guaranteed. [0003] In the existing substation grounding facilities: 1. Main grounding body: mainly the grounding system of the equipment area in the power grid, the connection structure is the ring network grounding of the main equipment; Select a grounding point. When this point is used as a temporary grounding point, it is easy to twist or break the grounding bolt of the equipment shell, and cause the grounding surface to be unreliab...
