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
The present invention relates to a kind of safe and reliable floating roof tank conducting strip.
Background technology
Oil is important strategic materials, is related to the development of national economy and the stable of society.Current country has established multiple large-scale national petroleum reserve base, and current oil reserve mainly adopts large-scale floating roof tank to carry out crude storage.Usually every 3m, a conducting strip is installed along floating roof tank secondary seal in current tank designs, carries out releasing of electrostatic charge and lightning current.In recent years the domestic floating roof tank fire incident also recurring a lot of crude oil storage and cause because of thunderbolt, by accident investigation and analysis, thinks that current conducting strip easily causes thunderbolt spark, causes storage tank fire incident.The tank skin contact area of existing conducting strip and floating roof tank is little, and needs to rely on the elastic force of external agency and the tank skin reliable contacts of floating roof tank, installs complicated.
Summary of the invention
In order to solve the deficiencies in the prior art, the present invention proposes a kind of safe and reliable floating roof tank conducting strip.This floating roof tank conducting strip relies on the tank skin reliable contacts of natural resiliency and floating roof tank.
The present invention adopts following technical scheme:
A kind of safe and reliable floating roof tank conducting strip, comprise metallic conduction sheet and set bolt, described metallic conduction sheet comprises arc section, lower arc section and horizontal segment, upper arc section, lower arc section and horizontal segment are one-body molded, upper arc section and lower arc section point of contact place are connected to form contact-making surface, contact-making surface is near tank skin, and the metallic conduction sheet be made up of upper arc section and lower arc section relies on its own resilient to contact with tank skin;
The lower circular sliding slopes horizontal segment of described metallic conduction sheet, horizontal segment is fixed on secondary seal rubber ring by set bolt.
Preferably, the distance of described contact-making surface distance secondary seal rubber ring is 20cm-50cm.
Preferably, described metallic conduction sheet adopts corrosion-resistant metal materials to make.
Preferably, the width of described metallic conduction sheet is 8cm-20cm, and contact-making surface and tank skin are that face contacts.
Preferably, described metallic conduction sheet self has elasticity, and metallic conduction sheet contacts elastic force with tank skin and is greater than 20N.
Preferably, insulation spacer is installed additional between described set bolt and metallic conduction sheet.
Preferably, the distance of described secondary seal rubber ring and tank skin is 20cm-25cm, ensures releasing of oil gas.
Advantageous Effects of the present invention is:
The reliable floating roof tank conducting strip of safety, comprise metallic conduction sheet and set bolt, metallic conduction sheet relies on its own resilient to contact with tank skin, without the need to external auxiliary installing mechanism, the safety relief of electrostatic charge of oil can be realized, conducting strip lightning current can also be reduced to release the probability of process sparkover, reduce and eliminate the storage tank lightning fire accident that existing conducting strip causes, ensure that the anti-lightning electrostatic proof safety of storage tank runs.
Accompanying drawing explanation
Fig. 1 is safe and reliable floating roof tank conducting strip structure schematic diagram.
Embodiment
1 pair of the specific embodiment of the present invention is described further by reference to the accompanying drawings:
A safe and reliable floating roof tank conducting strip, comprises metallic conduction sheet and set bolt.Metallic conduction sheet comprises arc section 1, lower arc section 3 and horizontal segment 5, upper arc section 1, lower arc section 3 and horizontal segment 5 are one-body molded, upper arc section 1 and lower arc section 3 point of contact place are connected to form contact-making surface 2, contact-making surface 2 is near tank skin, and the metallic conduction sheet be made up of upper arc section 1 and lower arc section 3 relies on its own resilient to contact with tank skin.The distance L1 of contact-making surface distance secondary seal rubber ring is 20cm-50cm, avoids the distance of the contact-making surface of conducting strip and tank skin and secondary seal circle too near.Metallic conduction sheet adopts corrosion-resistant metal materials to make.The width of metallic conduction sheet is 8cm-20cm, and contact-making surface and tank skin are that face contacts, and storage tank can normally be elevated.
