Abstract
The utility model discloses a lightning rod for a boring tower, and the lightning rod comprises at least three rod bodies which are connected with a supporting rod through a high-voltage ceramic. The high-voltage ceramic is provided with connecting wires which are connected with the rod bodies. One end of each connecting wire is firmly fixed on the high-voltage ceramic through a bolt, and the other end of each connecting wire is connected in a bottom-sealed steel pipe on the ground. Each rod body comprises a central rod body disposed at the center of the high-voltage ceramic, and also comprises inclined rod units which are uniformly distributed at the periphery of the high-voltage ceramic. The lightning rod provided by the utility model is simple in structure, is low in cost, is high in reliability of protection, is high in strength, and is resistant to heat. A supporting rod of the lightning rod is coated with zinc, and is resistant to corrosion. Moreover, the rod bodies of the lightning rod comprise a plurality of inclined rod units which have larger cover areas than a conventional single-rod lightning rod, thereby enabling the protection range to be wider and reliability to be good. A receiver is firm, is resistant to vibration, and is good in conductivity. The high-voltage ceramic is used for partitioning the lightning rod and the supporting rod, and is safe and practical. The bottom-sealed steel pipe for a ground electrode is filled with crude salt, thereby guaranteeing the ground resistance to be lower than 15 Ohm.
Description
Technical field
The utility model relates to power technology field, is specifically related to a kind of boring tower lightning rod.
Background technology
Hydrogeology, engineering geology, the fields such as heat construction, geological prospecting, natural petroleum gas field, owing to being outdoor field work, rainy season drilling operation, in spacious field, towering boring tower, the derrick straight cutting high in the clouds standing, seeming of injury accident that how to prevent from being struck by lightning is particularly important, and design and installation lightning rod is one of effective lightning protection measures.Lightning rod can play the reason of protective action, be because position is higher, and ground connection is good; near thunder and lightning approaches lightning rod; to lightning rod main discharge, its discharging current is imported into underground by lightning rod and earthing device thereof, thereby has protected the object within the scope of certain space to exempt from direct stroke.
Lightning rod is composed in series by arrester, down conductor and earth electrode three parts.The position of arrester is higher than boring tower top; But the lightning rod using at present can melt because of overheated, and mechanical strength is little, easily bending, and lightning current can not scatter equably in the time flowing into the earth.
Utility model content
The deficiency existing for prior art, the purpose of this utility model is to provide a kind of simple in structure, with low cost, protection reliability is high, intensity is high and heat-resisting boring tower lightning rod.
To achieve these goals, the technical solution adopted in the utility model is: comprise at least three needle bodies, needle body connects a support bar by higfh-tension ceramics, on higfh-tension ceramics, be provided with the connecting line being connected with needle body, connecting line one end is by bolted on higfh-tension ceramics, and the other end is connected in a back cover steel pipe on ground; Needle body comprises and is arranged on the middle needle body of higfh-tension ceramics center position and is evenly distributed on the oblique needle body on higfh-tension ceramics circumference.
Tiltedly needle body and axis angle are 30～60 degree, and needle body is red copper needle body, and its outside diameter is 12mm.
In back cover steel pipe, be filled with crude salt.
Support bar surface scribbles one deck zinc layer.
Connecting line adopts 25mm
2copper cable or 30mm
2aluminium matter cable.
The beneficial effects of the utility model are: have advantages of simple in structure, with low cost, protection reliability is high, intensity is high and heat-resisting; Lightning rod support bar position is zinc-plated, corrosion-resistant, and needle body of the present utility model comprises multiple oblique needle bodies, and the single needle lightning rod of current use is compared in its covering, and its area coverage is large, thereby its protection range is larger, good reliability; Adopt Φ 10mm copper rod to make receiver, firm vibration resistance, good conductivity; Lightning rod and support bar are separated with high-tension porcelain insulator (puncture voltage be greater than 10kV more than), safe and practical; Earth electrode is made with filling crude salt in back cover steel pipe, guarantees that earth resistance is below 15 ohm.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, boring tower lightning rod of the present utility model, comprise three needle bodies 1, needle body 1 connects a support bar 3 by higfh-tension ceramics 2, on higfh-tension ceramics 2, be provided with the connecting line 4 being connected with needle body 1, connecting line 4 one end are by bolted on higfh-tension ceramics 2, and the other end is connected in a back cover steel pipe 5 on ground, needle body 1 comprises and is arranged on the middle needle body 6 of higfh-tension ceramics 2 center positions and is evenly distributed on the oblique needle body 7 on higfh-tension ceramics 2 circumference, and tiltedly needle body 7 is 30～60 degree with axis angle; Needle body 1 is red copper needle body, and its outside diameter is 12mm.Lightning rod support bar 3 positions are zinc-plated, corrosion-resistant, and needle body of the present utility model 1 comprises two oblique needle bodies 7, and the single needle lightning rod of current use is compared in its covering, and its area coverage is large, thereby its protection range is larger, good reliability.
In the present embodiment, in back cover steel pipe 5, be filled with crude salt, guarantee that earth resistance is below 15 ohm, thus smoothly thunder is incorporated into smoothly underground, protection boring tower and staff's personal safety.
In the present embodiment, support bar 3 surfaces scribble one deck zinc layer, and its support bar 3 is corrosion-resistant, extend its useful life.
In the present embodiment, connecting line 4 adopts 25mm
2copper cable or 30mm
2aluminium matter cable, its cable resistance is less, and conduction is better.
