Abstract
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
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 stablizing of society.Country has built at present
Stand multiple large-scale national petroleum reserve base, current oil reserve mainly carries out crude storage using large-scale floating roof tank.
Generally every 3m, one conducting strip is installed along floating roof tank secondary seal in tank designs at present, carries out electrostatic charge and lightning current
Release.In recent years domestic also recur the floating roof tank fire incident that a lot of crude oil storages cause because of thunderbolt, by accident investigation
And analysis, it is believed that current conducting strip easily causes thunderbolt spark, causes storage tank fire incident.Existing conducting strip and floating roof tank
Tank skin contact area little, and need to rely on the tank skin reliable contacts of elastic force and the floating roof tank of external agency, install complicated.
Content 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 is floating
Top storage tank conducting strip relies on the tank skin reliable contacts of natural resiliency and floating roof tank.
The present invention adopts the following technical scheme that：
A kind of safe and reliable floating roof tank conducting strip, including metallic conduction piece and fixing bolt, described metallic conduction piece
Including upper arc section, lower arc section and horizontal segment, upper arc section, lower arc section and horizontal segment are integrally formed, upper arc section and
Connect at lower arc section point of contact and form contact surface, contact surface, against tank skin, is led by the metal that upper arc section and lower arc section form
Electric piece relies on its own resilient to contact with tank skin；
The lower circular sliding slopes horizontal segment of described metallic conduction piece, horizontal segment is fixed on secondary seal rubber by fixing bolt
On circle.
Preferably, described contact surface is 20cm-50cm apart from the distance of secondary seal rubber ring.
Preferably, described metallic conduction piece is made using corrosion-resistant metal materials.
Preferably, the width of described metallic conduction piece is 8cm-20cm, and contact surface is contacted for face with tank skin.
Preferably, described metallic conduction piece itself has elasticity, and metallic conduction piece is contacted elastic force and is more than 20N with tank skin.
Preferably, install insulation spacer additional between described fixing bolt and metallic conduction piece.
Preferably, the distance of described secondary seal rubber ring and tank skin is 20cm-25cm it is ensured that the releasing of oil gas.
The method have the benefit that：
Safety reliable floating roof tank conducting strip, including metallic conduction piece and fixing bolt, metallic conduction piece relies on certainly
Body elastic force is contacted with tank skin, without external auxiliary installing mechanism, it is possible to achieve the safety relief of electrostatic charge of oil, can also reduce and lead
Electric piece lightning current is released the probability of process spark discharge, reduces 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.
Brief description
Fig. 1 is safe and reliable floating roof tank conducting strip structure schematic diagram.
Specific embodiment
In conjunction with accompanying drawing 1, the specific embodiment of the present invention is described further：
A kind of safe and reliable floating roof tank conducting strip, including metallic conduction piece and fixing bolt.Metallic conduction piece includes
Upper arc section 1, lower arc section 3 and horizontal segment 5, upper arc section 1, lower arc section 3 and horizontal segment 5 are integrally formed, upper arc section
1 and lower arc section 3 point of contact at connect formed contact surface 2, contact surface 2 against tank skin, by upper arc section 1 and 3 groups of lower arc section
The metallic conduction piece becoming relies on its own resilient to contact with tank skin.Contact surface is 20cm- apart from secondary seal rubber ring apart from L1
50cm, it is to avoid conducting strip is too near with the distance of secondary seal circle with the contact surface of tank skin.Metallic conduction piece adopts corrosion resistant metal
Material is made.The width of metallic conduction piece is 8cm-20cm, and contact surface is contacted for face with tank skin, and storage tank can normally lift.
Preferably, described metallic conduction piece itself has elasticity, and metallic conduction piece is contacted elastic force and is more than 20N, no with tank skin
External auxiliary installing mechanism is needed just to contact with tank skin.
The lower circular arc 3 of metallic conduction piece connects horizontal segment 5, and horizontal segment 5 is fixed on secondary seal rubber by fixing bolt 4
On circle, between fixing bolt 4 and metallic conduction piece, install insulation spacer additional.Secondary seal rubber ring is 20cm- with the distance of tank skin
25cm is it is ensured that the releasing of oil gas.
Certainly, only presently preferred embodiments of the present invention described above, the present invention is not limited to enumerate above-described embodiment, should
When explanation, any those of ordinary skill in the art are under the guidance of this specification, all equivalent substitutes of being made, bright
Aobvious variant, all falls within the essential scope of this specification, ought to be protected by the present invention.
