Abstract
The utility model discloses a temporary ground bar consisting of a helical bar body and an operating handle; the operating handle is fixed or detachably fixed on the upper end of the helical bar body without rotating; and a connecting hole or connecting element connected with a grounding wire is arranged on the upper end of the helical bar body away from the lower end for more than 60 cm. The temporary ground bar provided by the utility model is convenient to insert in and pull out from the ground, thereby being convenient in operation and application, saving time and labor, having high working efficiency and effectively solving the inserting and pulling difficulty of construction workers caused by dryness and hardness, clay belts and frozen earth layers; the temporary ground bar has small grounding resistance and high safety, thereby providing maximal safety guarantee for construction workers and reducing the accident rate; and the temporary ground bar is simple in manufacture and low in cost.
Description
Technical field
The utility model belongs to the indispensable safety appliance that power construction operation ground connection is used, and relates to a kind of temporary grounding rod.
Background technology
When on the equipment that has a power failure, working, ground connection is answered at the job site two ends, and to guarantee staff's personal safety, the temporary grounding rod is the indispensable safety appliance that power construction operation ground connection is used.When using the temporary grounding rod, " electric power safety working regulation (power circuit part) (trying) " 3.4.7 requires the earth rod buried depth to be not less than 60 centimeters, makes earth resistance enough little, to guarantee staff's personal safety.The present temporary grounding rod that extensively adopts of power industry, its barred body surface smoothing when meeting arid, hard, clay ground and frozen soil layer, is very difficultly wedged undergroundly, causes the earth rod buried depth not enough, and earth resistance can not satisfy the rules requirement.Even stiff wedging reaches the buried depth requirement, because the barred body buried depth more than 60 centimeters, when removing earth rod, is difficult to extract smoothly, rigid extracting causes earth rod to damage easily, can only abandon when can not pulling out, and causes waste.
The utility model content
The purpose of the utility model is exactly to solve the problems referred to above that exist in the prior art, provides that a kind of convenience plug in ground, earth resistance is little, and the temporary grounding that fail safe is good is excellent.
For realizing above-mentioned purpose, the technical solution of the utility model is: a kind of temporary grounding rod, and it is made up of barred body and operating grip; Barred body is the screw type bit form, and operating grip removably is not fixed on the upper end of barred body revolvably, in the upper end of the barred body more than the 60CM of lower end connecting hole or the connector that is connected with earth connection is arranged.
On the above-mentioned described barred body in that there is buried depth sign at the 60CM place from the lower end.
The structure that above-mentioned said operating grip removably is not fixed on the upper end of barred body revolvably is: the barred body upper end is a rectangle or square; The endoporus of the vertical tube connector of operating grip is for perhaps square with the rectangle or the square rectangle that is complementary of barred body upper end; The two corresponding position has one or two bolt connecting holes of same diameter, and bolt connecting hole is connected fixing by bolt.The utility model is screwed in when underground, can directly the barred body upper end be inserted in the operating grip, and not use bolt to connect, only when dismounting the utility model, use bolt to connect, the utility model is screwed out ground.
The barred body of the utility model has been processed the screw type bit form; Increased the contact area of earth rod and the earth; The earth rod contact area of more existing same diameter has increased more than 1/3, effectively reduces earth resistance, makes the earth resistance resistance descend about 26%; Avoided the injury to the construction operation personnel such as induced voltage, leakage current, safe.Add operating grip on the earth rod top, during use, through rotating operating handle can with its successfully screw in underground with extract; Conveniently in ground, plug, time saving and energy saving, simple to operate; Under identical construction environment condition, operating efficiency than former raising more than 2 times, as in the winter time; The job site that hangs 4 winding ground wires with need is an example; Adopt the earth rod earth rod installation compared with before-improvement after improving to save time about 3 hours, shortened interruption duration, improved social benefit and economic benefit.The buried depth sign that 60CM is arranged on earth rod, convenient in use contrast.And operating grip is quick detachable, after the installation, can operating grip be taken off, and only stays the barred body that pierces ground, has increased the disguise of earth rod, has avoided the potential safety hazard of bringing owing to losing of earth rod.
In a word, the utility model is convenient to plug in ground, easy for operation, time saving and energy saving, and high efficiency efficiently solves the plug difficult problem that stiff, clay Belt and frozen soil layer bring for the construction operation personnel; Earth resistance is little, and is safe, for the construction operation personnel provide maximum safety guarantee, reduced rate of failure; Make simple, with low cost.

Embodiment
As depicted in figs. 1 and 2, present embodiment is made up of barred body 1 and operating grip 4.Barred body 1 is the screw type bit form, has two connecting holes 2 that are connected with earth connection in 1 upper end of the barred body more than the 60CM of lower end.Barred body 1 upper end is a rectangle, the rectangle that the endoporus of the vertical tube connector 5 of operating grip 4 is complementary for the rectangle with barred body 1 upper end.The connecting hole 2 corresponding positions of operating grip 4 and barred body 1 upper end have the bolt connecting hole of same diameter, and during use, bolt connecting hole can connect fixing by bolt 3; After screwing in ground, pull down 4, two connecting holes of operating grip 2 and connect earth connection; During dismounting; Then earlier earth connection is removed, again operating grip 4 usefulness bolts 3 are connected fixedly on the barred body 1 back-out ground.On the barred body 1 in that there is the buried depth sign 6 of red lacquer brushing at the 60CM place from the lower end.
Claims (3)
