Problems solved by technology
In recent years, there have been many fire accidents of floating roof storage tanks caused by lightning strikes in crude oil depots in China. Through accident investigation and analysis, it is believed that the current conductive sheet is easy to cause lightning sparks and cause fire accidents in storage tanks.
The contact area between the existing conductive sheet and the tank wall of the floating roof storage tank is small, and it needs to rely on the elastic force of the external mechanism to make reliable contact with the tank wall of the floating roof storage tank, so the installation is complicated

Embodiment Construction
[0016] Attached figure 1 The specific implementation of the present invention is further described:
[0017] A safe and reliable conductive sheet for a floating roof storage tank, which includes a metal conductive sheet and fixing bolts. The metal conductive sheet includes an upper arc section 1, a lower arc section 3, and a horizontal section 5. The upper arc section 1, a lower arc section 3, and a horizontal section 5 are integrally formed, and the upper arc section 1, and the lower arc The tangent points of the section 3 are connected to form a contact surface 2 which is close to the tank wall. The metal conductive sheet composed of the upper arc section 1 and the lower arc section 3 contacts the tank wall by its own elastic force. The distance L1 between the contact surface and the secondary sealing rubber ring is 20cm-50cm, to avoid the contact surface of the conductive sheet and the tank wall from being too close to the secondary sealing ring. The metal conductive sheet i...

The invention discloses a safe and reliable floating roof storage tank conductive piece which comprises a metal conductive piece and a fixing bolt. The metal conductive piece comprises an upper circular-arc section, a lower circular-arc section and a horizontal section which are integrally formed, the tangency point positions of the upper circular-arc section and the lower circular-arc section are connected to form a contact face, the contact face is tightly next to a tank wall, and the metal conductive piece formed by the upper circular-arc section and the lower circular-arc section is in contact with the tank wall by means of self elastic force. The lower circular-arc section of the metal conductive piece is connected with the horizontal section, and the horizontal section is fixed to a secondary seal rubber ring through the fixing bolt. Safe release of oil product static electricity can be achieved without an external auxiliary mechanism, the spark discharge probability of the conductive piece in the lightning current discharge process can be further reduced, storage tank lightning stroke fire disaster accidents caused by an existing conductive piece are decreased and eliminated, and lightning stroke resisting anti-static safe operation of a storage tank is guaranteed.
Description
Technical field [0001] The invention relates to a safe and reliable conductive sheet for a floating roof storage tank. Background technique [0002] Petroleum is an important strategic material, related to the development of the national economy and the stability of the society. At present, the country has established a number of large-scale national oil reserve bases. At present, the oil reserve mainly uses large floating-roof storage tanks for crude oil storage. At present, in the design of storage tanks, a conductive sheet is usually installed every 3m along the secondary seal of the floating roof tank to discharge electrostatic charge and lightning current. In recent years, there have been a number of fire accidents of floating roof storage tanks caused by lightning strikes in crude oil storage in China. Through accident investigation and analysis, it is believed that the current conductive sheets are easy to cause lightning sparks and cause storage tank fire accidents. The...
