The height of wind power generating set is generally about 100 meters, and wind field generally is selected in wide Plain or hills, is not higher than the building of blower fan height around the wind power generating set, so wind power generating set lightning-arrest is unusual important problem.The lightning-arrest mode of existing wind power generating set mainly is at the bottom welding steel of tower tube cylindrical shell or welding cylinder, the earth cable of the electrical equipment at tower tube cylindrical shell top is connected on steel plate or the welding cylinder, and then will be embedded in ground connection band iron in the earth and be fixedly connected on steel plate or the welding cylinder, make the electric current in the earth cable flow into the earth.But cause the welding part distortion of tower tube cylindrical shell easily at the bottom welding steel of tower tube cylindrical shell, because wind power generating set is had relatively high expectations to the mechanical property of cylindrical shell, therefore must proofread and correct deformation place, this kind method easily causes the hidden danger of potential barrel distortion, and deformation place is proofreaied and correct also time-consuming, expense material.Though and the form bonding area of employing welding cylinder is little, barrel distortion is little, but because the volume of welding cylinder is little, and earth cable quantity is very big, the position of therefore welding on the cylinder might connect whole earth cables inadequately, and this just need prolong the length of this part earth cable, allow these cables directly and the ground connection band iron overlap, so just have a lot of point of contact, cause the unreal hidden danger of point of contact easily.In addition because the negligible amounts of ground connection band iron, and the area that can contact is less, thereby the earth cable after prolonging exists usually and arrange in disorder problem, causes inspection of line difficulty, and prolongs the manufacture cost that earth cable also can improve wind power generating set.
Summary of the invention
At the problems referred to above, main purpose of the present utility model provides a kind of tower frame grounding device, and it can avoid welding the destruction that the tower tube cylindrical shell to wind power generating set causes, and cable connects really and can save the wind power generating set cost.
For achieving the above object, the utility model is taked following technological scheme: a kind of tower frame grounding device, described pylon have a tower barrel base ring and and are arranged on tower tube cylindrical shell on the described tower barrel base ring; It is characterized in that: it comprises an annular electric conductor, and described annular electric conductor is provided with some projectioies; The sidewall of described annular electric conductor is provided with some lines hole; Described annular electric conductor is fixedly connected on the inwall of tower barrel base ring by each described projection, and described annular electric conductor is fixedlyed connected with the ground connection band iron.
Described annular electric conductor adopts plurality of sections to combine.
The as a whole annular of described annular electric conductor.
Described annular electric conductor is circle or polygonal.
Described projection adopts circular arc type structure or rectangular configuration.
Described projection is welded on the tie point of each tower barrel base ring inwall or adopts bolton on described tie point, and the tie point of described each tower barrel base ring inwall is the welded post of tower barrel base ring inwall.
It is that circle, ring, rectangle or leg-of-mutton conductive material are made that described annular electric conductor adopts cross section.
The utility model is owing to take above technological scheme, it has the following advantages: 1, the utility model is fixedlyed connected annular electric conductor owing to having adopted with each tie point on the tower barrel base ring, earth cable is connected on the annular electric conductor again, therefore can avoid tower tube barrel distortion, and all earth cable all can be connected on the annular electric conductor, saves the wind-driven generator cost thereby need not prolong earth cable.2, the utility model can be according to processing line hole nearby on the sidewall of loop configuration, the position of earth cable, and earth cable is worn behind the cable-through hole and be fixing, therefore has earth cable and arranges in order the advantage that the tie point of each earth cable and annular electric conductor is firm.The utility model can be widely used in the lightning protection of blower fan.
