Abstract
The utility model discloses a power concrete rod with a grounding wire. The power concrete rod comprises a tubular concrete round rod body with a certain taper, wherein a circular cage shaped steel reinforcement framework is arranged in the tubular concrete round rod body with a certain taper; the circular cage shaped steel reinforcement framework is provided with steel reinforcement circular rings which are uniformly distributed along the length direction of the power concrete rod; straight steel reinforcements along the length direction of the power concrete rod are uniformly connected between the steel reinforcement circular rings along the circumferences of the circular rings; a steel pipe section connected with the circular cage shaped steel reinforcement framework is coated at the lower end of the tubular concrete round rod body with a certain taper; and the upper part and the middle part of the tubular concrete round rod body with a certain taper are respectively provided with radial internal thread pipes connected with the steel reinforcement framework. The power concrete rod is not required to be additionally provided with a grounding device and is convenient and labor-saving, the grounding wire is not exposed, and the power concrete rod has small possibility of being damaged during use.
Description
Technical field
The utility model relates to a kind of electric power concrete bar, particularly a kind of ground device of electric power concrete bar.
Background technology
Electric power concrete bar, i.e. the electric force pole tower that is made of steel concrete, electric power concrete bar cooperates the gold utensil annexes such as cross-arm that are fastened on the concrete bar to be used to support built on stilts power circuit, and electric force pole tower is mainly used in 35kV and following power circuit.Electric power concrete bar has the tubular concrete round bar body with certain taper; Have in the tubular concrete round bar body of certain taper large carrying food-basket shape cage of reinforcement is arranged; Large carrying food-basket shape cage of reinforcement has the reinforcing bar annulus that is uniformly distributed with along electric power concrete pole length direction, between the reinforcing bar annulus, be connected with along the straight reinforcing bar of electric power concrete pole length direction along the circumference uniform distribution of annulus.Tubular concrete round bar body with certain taper is the tubular concrete round bar body with certain taper that is cast on the large carrying food-basket shape cage of reinforcement.
If electric power concrete bar is longer, short straight reinforcing bar can be linked to be the identical length of length with electric power concrete bar with the method for welding.
During use, electric power concrete bar is vertically to be embedded on the ground, is fastened with the cross-arm of level in the upper end of electric power concrete bar, and cross-arm is put on the shelf and is provided with power line.
When the power line interruption maintenance, the power line of electric power concrete bar top is wanted ground connection, and for power line ground connection, electric power concrete bar will have ground device.
In the prior art, the ground device of electric power concrete bar has along the earth lead of electric power concrete pole length direction, and the lower end of earth lead is connected with the earth bar that is embedded in underground certain depth, and the upper end of earth lead is connected with electric contact.During power line ground connection, the upper end electric contact of earth lead is clamped on the power line through ground clamp, realizes the ground connection of power line.
The earth lead of the ground device of this electric power concrete bar and earth anchor all are and electric power concrete bar separated components that than trouble, the earth lead that exposes from top to bottom in the use damaged easily when ground device was installed.
Summary of the invention
The purpose of the utility model is in order to overcome above-mentioned deficiency, proposes a kind ofly to have easy for installationly, does not allow the electric power concrete bar with grounding wire of flimsy ground device in the use.
The utility model is realized with following method.
Electric power concrete bar with grounding wire has the tubular concrete round bar body with certain taper; Have in the tubular concrete round bar body of certain taper large carrying food-basket shape cage of reinforcement is arranged; Large carrying food-basket shape cage of reinforcement has the reinforcing bar annulus that is uniformly distributed with along electric power concrete pole length direction; Between the reinforcing bar annulus, be connected with along the straight reinforcing bar of electric power concrete pole length direction along the circumference uniform distribution of annulus; Lower end with tubular concrete round bar of certain taper is surrounded by the lengths of steel pipes that links to each other with large carrying food-basket shape cage of reinforcement, and the top with tubular concrete round bar of certain taper has the radially riffled tube that links to each other with cage of reinforcement respectively with the middle part.
During use; Be embedded in the lower end of the utility model underground, the lengths of steel pipes of lower end with tubular concrete round bar of certain taper can be used as earth bar and is buried under the ground, and is electric contact with the radially riffled tube on top; Use the screw precession riffled tube that matches with the internal thread of riffled tube; Be connected in lead on the electric contact, be clamped on the power line, just can realize overhead power transmission line and ground connection through the ground clamp that links to each other with lead; If when in the centre of the utility model transformer platform being installed, the radially riffled tube that links to each other with cage of reinforcement at the utility model middle part can be used as the ground connection electric contact of facility on the transformer platform.
There is the lengths of steel pipes that links to each other with cage of reinforcement the lower end of the utility model, and the radially riffled tube of cage of reinforcement and top and middle part is formed the ground device of electric power concrete bar, after the utility model uprightly is embedded on the ground; Lengths of steel pipes is to be embedded in underground earth bar; Cage of reinforcement is an earth lead, and the radially riffled tube at top and middle part is the ground connection electric contact, and electric power concrete bar need not be installed ground device separately; Convenient, saving of labor, earth lead does not expose in the use not fragile.
Below in conjunction with accompanying drawing, the utility model is done explanation further.
Description of drawings
Fig. 1 cuts open sketch map according to a kind of master office of looking with electric power concrete bar of grounding wire of the invention scheme proposition of the utility model.
The specific embodiment
Among Fig. 1; Electric power concrete bar with grounding wire has the tubular concrete round bar body 1 with certain taper; Have in the tubular concrete round bar body of certain taper large carrying food-basket shape cage of reinforcement 2 is arranged; Large carrying food-basket shape cage of reinforcement has the reinforcing bar annulus 3 that is uniformly distributed with along electric power concrete pole length direction; Between the reinforcing bar annulus, be connected with along the straight reinforcing bar 4 of electric power concrete pole length direction along the circumference uniform distribution of annulus, the lower end with tubular concrete round bar of certain taper is surrounded by the lengths of steel pipes 5 that links to each other with large carrying food-basket shape cage of reinforcement, and the top with tubular concrete round bar of certain taper has the radially riffled tube 6,7 that links to each other with cage of reinforcement respectively with the middle part.
The connecting place of large carrying food-basket shape cage of reinforcement is continuous with the method for welding.
