Description
Technical Field
The utility model belongs to the technical field of the lightning protection technique and specifically relates to a lightning protection device of gas pipeline is related to.
Background
If effective lightning protection measures are not taken or lightning protection facilities fail, the consequences of accidents caused by lightning strike are particularly serious. In direct lightning strikes, the lightning discharges directly through metal pipes and equipment to ground. In indirect lightning strike, strong lightning current invades indoors through metal pipelines, causes mechanical and insulating damages of pipelines, equipment, valves, instruments, electrical appliances, cables and communication, and can cause gas leakage and combustion or explosion accidents in severe cases. Indoor gas pipelines are protected by lightning protection facilities of buildings, underground gas pipelines are covered and protected by soil layers, and the possibility of direct lightning strike is extremely low. Outdoor open-air gas piping facilities that are not within the protective confines of the building lightning protection facilities may be the best path for lightning, and the possibility of lightning strikes during operation is present.
How to avoid the damage of the gas pipeline caused by the lightning strike is a significant social problem. Based on the above, the invention designs a lightning protection device for a gas pipeline, so as to solve the above problems.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a lightning protection device of gas pipeline protects the gas pipeline effectively, avoids it to suffer the thunderbolt injury.
In order to achieve the above object, the utility model provides a following technical scheme:
the utility model provides a lightning protection device of gas pipeline, includes lightning rod branch, needle point, metal sleeve, flexible rubber material, buckle, gas pipeline, earth connection and grounding body.
The needle point is used as a lightning arrester and is vertically fixed on the lightning rod support rod; the lightning rod support rod is vertically fixed on the metal sleeve; the metal sleeve is arranged outside the gas pipeline by adopting a buckle; the two buckles are respectively arranged on the left side and the right side of the metal sleeve; flexible rubber materials are filled between the gas pipeline and the metal sleeve; one end of the grounding wire is connected with the metal sleeve in a welding mode, and the other end of the grounding wire is connected with the grounding body.
Further, the lightning rod support rod uses a metal rod.
Further, the needle tip uses galvanized round steel with the diameter not less than 25 mm.
Furthermore, the metal sleeve is made of stainless steel, and the wall thickness is larger than 4 mm.
Furthermore, the grounding wire uses the whole conductive wire and is connected to the grounding body in an unbent mode as far as possible.
Furthermore, the grounding body is made of steel pipes, the length of the grounding body is 1.5 m to 2 m, the grounding body is buried in the ground, and the buried depth is more than 2 m.
Compared with the prior art, the beneficial effects of the utility model are that: the device can protect the thin-wall steel pipe and other gas pipelines needing lightning protection, and prevent the thin-wall steel pipe and other gas pipelines from being damaged by lightning. Meanwhile, compared with the mode of additionally arranging the lightning rod and the like, the device is low in cost. Can be widely popularized and used. The metal sleeve can protect the gas pipeline completely, the length of the metal sleeve can be determined according to the field condition, and a plurality of small sections of lightning protection devices can be additionally arranged on a long straight pipeline to realize large-scale protection.
