Background technique
Petroleum is important strategic materials, is related to the development of national economy and the stabilization of society.Oil tank oil storage is current
Using a kind of main and universal oil storage mode, China has been set up multiple large-scale national petroleum reserve bases, and oil tank
Area is mostly built in the Lightning Disasters such as riverine, coastal hotspots, and storage tank is subject to be struck by lightning on fire.In recent years the country also recurs a lot of
Crude oil storage is because of floating roof tank fire incident caused by being struck by lightning, this is relatively large in diameter with storage tank floating roof, and it is bright that direct lightning strike hits floating roof probability
Aobvious increase is related.
To avoid thunder and lightning from attacking the generation that floating roof causes storage tank blast accident directly, need for floating roof to be in lightning protected range
It is interior, but floating roof area is excessive, effective protection can not be carried out by only relying on traditional direct lightning stroke protective method.
Summary of the invention
For the above-mentioned problems in the prior art, the invention proposes a kind of to dodge the outer floating of band and metal roof with connecing
Storage tank is pushed up, a metal roof is set up outside floating roof, carries out reliable electric connection with tank body, metal roof can not only reduce rainwater, sun
Influence of the natural causes such as light to contents, but also can effectively avoid harm of the tank inside by lightning induction, connect sudden strain of a muscle
Band is arranged above metal roof, carries out reliable electric connection with metal plate, realizes direct lightning strike protection to metal roof, avoids thunder
Electricity attacks the metal roof of External floating roof tank directly, considerably reduces the generation of lightning stroke storage tank fire incident.
To achieve the goals above, the present invention adopts the following technical scheme that：
It is a kind of including tank body, floating roof, metal roof, to connect sudden strain of a muscle band with connecing the External floating roof tank for dodging band and metal roof, in floating roof
One metal roof of outer erection, pillar are welded with tank deck angle steel, carry out reliable electric connection with tank body.It is set above metal dome
It sets and connects sudden strain of a muscle band, sudden strain of a muscle band will be connect and be fixed on the securing supports on preparatory mounted metal plate, the crosspoint dodged between line is connect
Reliable welding connects sudden strain of a muscle band using hot dip galvanizing steel strand or copper stranded conductor, and sectional area is not less than 50mm2.Rolling ball method calculating connects sudden strain of a muscle line
Protection scope, determine to connect and dodge the quantity of line, position.It connects sudden strain of a muscle band to be arranged above metal roof, metal roof and storage tank is realized
Direct lightning strike protection, avoids thunder and lightning breakdown metal roof, and metal roof can not only reduce the natural causes such as rainwater, sunlight to internal attached
The influence of part, but also can effectively avoid harm of the tank inside by lightning induction, it realizes to the multiple of External floating roof tank
Lightning Protection considerably reduces the generation of lightning stroke storage tank fire incident.
Preferably, it is described it is a kind of with connect dodge band and metal roof External floating roof tank, a metal roof is set up outside floating roof, prop up
Column is welded with tank deck angle steel, carries out reliable electric connection with tank body.
Preferably, the metal plate uses aluminium or other metal materials, and connection should be lasting electrical perforation between plate, realizes
To the electromagnetic shielding in top.
Preferably, a kind of with the External floating roof tank for dodging band and metal roof is connect, setting connects sudden strain of a muscle band above metal dome, will
It connects sudden strain of a muscle band to be fixed on the securing supports on preparatory mounted metal plate, carries out reliable electric connection with metal plate.
Preferably, the sudden strain of a muscle band that connects is using hot dip galvanizing steel strand or copper stranded conductor, and sectional area is not less than 50mm2。
Preferably, the quantity for connecing sudden strain of a muscle line, position are calculated by rolling ball method connects the protection scope for dodging line to determine.
The invention has the advantages that：
It is a kind of to set up a metal roof outside floating roof with the External floating roof tank for dodging band and metal roof is connect, it connects sudden strain of a muscle band and is arranged in gold
Belong to above top, carry out reliable electric connection with metal plate, direct lightning strike protection is realized to metal roof, avoids thunder and lightning and attack outer float directly
The metal roof of storage tank is pushed up, metal roof can not only reduce influence of the natural causes such as rainwater, sunlight to contents, but also can
Harm of the tank inside by lightning induction effectively is avoided, the multiple lightning Protection to External floating roof tank is realized, significantly drops
The generation of low lightning stroke storage tank fire incident.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of External floating roof tank in the present invention；
Fig. 2 is storage tank top view；
Specific embodiment
With reference to the accompanying drawing and specific embodiment invention is further described in detail：
As shown in Figure 1, Figure 2, a kind of with the External floating roof tank for connecing sudden strain of a muscle band and metal roof, including tank body, floating roof, metal
It pushes up, connect sudden strain of a muscle band, a metal roof is set up outside floating roof, setting connects sudden strain of a muscle band above metal roof.
Metal plate is welded using aluminium or other metal materials, pillar with tank deck angle steel, carries out reliable electric with tank body
