telescopic conductor

Abstract

The invention discloses a telescopic conductor. The telescopic conductor comprises a fixed frame which is fixed on a floating roof foam weir plate of a floating roof storage tank, a short telescopic rod hinged with the top end of the fixed frame, and a long telescopic rod hinged with the bottom end of the fixed frame, the other end of the short telescopic rod is connected and fixed on the long telescopic rod with position adjustable, the other end of the long telescopic rod is connected with one supporting plate, a static piece is fixed on the supporting plate, and is contacted with the inner wall of the floating roof storage tank, the long telescopic rod and the short telescopic rod respectively comprise at least two rod sections, the two corresponding rod sections are connected by adopting a sheathing way and are elastically connected with each other by virtue of an energy storage spring, the static piece is elastically contacted and compresses the inner wall of the floating roof storage tank by virtue of elastic force of the energy storage spring, and the fixed frame and the static piece are in conductive connection. According to the telescopic conductor disclosed by the invention, conductive contact is more stable, electric connection quality is better, good conducting state is always kept, anti-static and anti-lightning effects are better, and no static or lightning hidden trouble exists, thereby being safer and securer.

Description

technical field [0001] The invention relates to the technical field of lightning protection and antistatic technology for petroleum and chemical storage tanks, in particular to a telescopic conductor used for storage tanks with floating roofs. Background technique [0002] In order to comply with the requirements of the petrochemical anti-static grounding specification for the existing external floating roof storage tanks and the requirements of the petrochemical lightning protection facility specification, the existing practice is that the lightning protection and anti-static connection of the external floating roof storage tank is mostly used in the secondary seal The compression spring type conductive connection is made at the place. During the application process of this structure, there will be failures such as the compression spring coming out of contact, the oil stain on the tank wall, and poor conductivity. Moreover, the existing electrostatic sheet is installed in an...

[0002] In order to comply with the requirements of the petrochemical anti-static grounding specification for the existing external floating roof storage tanks and the requirements of the petrochemical lightning protection facility specification, the existing practice is that the lightning protection and anti-static connection of the external floating roof storage tank is mostly used in the secondary seal The compression spring type conductive connection is made at the place. During the application process of this structure, there will be failures such as the compression spring coming out of contact, the oil stain on the tank wall, and poor conductivity. Moreover, the existing electrostatic sheet is installed in an area with a high oil vapor concentration. Easy to produce discharge and lightning accidents
