Description
この固定屋根式の貯蔵タンクＴにおいては、比較的に軽微な地震を原因として生じるスロッシング現象により、貯蔵タンクＴ内の液体Ｗに小さな波が発生した場合であっても、発生した波により屋根部分が破損する等の事態の発生を防ぎ、これに充分に対応するために、液面と屋根部分の間に所定の間隔を保持している。
また、波により屋根部分が破損する等の事態の発生を防ぐために、特許文献１乃至３の技術が提案されている。
特許文献１は、貯槽の貯蔵液表面に浮上して配設された浮屋根と、振動により貯蔵液に発生するスロッシングを抑制するために貯蔵液中に配設された反スロッシング力を発生させる抵抗板と、上記抵抗板の反スロッシング力を上記浮屋根に伝達するために、上記抵抗板と上記浮屋根と平行に係合する作動軸とを備えた液体貯槽のスロッシング抑制装置を開示している。
また、特許文献２は、上部を開口したタンク本体と、該タンク本体内に貯蔵した液体の液面上に浮かべた浮屋根とを具える浮屋根式タンクにおいて、前記浮屋根の下面に、略十字状または略格子状に配列した複数の揺れ止め板を、当該浮屋根下面から下方に延在させて設けた浮屋根式タンクを開示している。
さらに、特許文献３は、タンクに貯留された液体を覆う浮き屋根の下側に配置されるフロート構造体と、前記フロート構造体に支持され、前記液体の流速を減衰させる減衰体と、を備え、前記フロート構造体が、複数の棒状要素を組み合わせてなる平面架構と、前記浮き屋根との接触による前記平面架構の損傷を防止する緩衝材とを具備しているスロッシング減衰装置であって、前記緩衝材をリング状又はＣ字状に成形して前記棒状要素に外嵌したスロッシング減衰装置を開示している。
In this fixed roof type storage tank T, even if a small wave is generated in the liquid W in the storage tank T due to a sloshing phenomenon caused by a relatively minor earthquake, the roof portion is caused by the generated wave. In order to prevent the occurrence of a situation such as breakage and to sufficiently cope with this, a predetermined interval is maintained between the liquid surface and the roof portion.
In order to prevent the occurrence of a situation such as the roof portion being damaged by waves, the techniques of Patent Documents 1 to 3 have been proposed.
Patent Document 1 discloses a floating roof that is floated and disposed on the surface of a storage liquid in a storage tank, and a resistance that generates an anti-sloshing force that is disposed in the storage liquid in order to suppress sloshing generated in the storage liquid due to vibration. Disclosed is a sloshing suppression device for a liquid storage tank comprising a plate and an operating shaft that engages the resistance plate and the floating roof in parallel to transmit the anti-sloshing force of the resistance plate to the floating roof. .
Patent Document 2 discloses a floating roof tank comprising a tank body having an upper opening and a floating roof floated on the liquid surface stored in the tank body. A floating roof type tank is disclosed in which a plurality of anti-sway plates arranged in a cross shape or a substantially lattice shape are provided extending downward from the bottom surface of the floating roof.
Further, Patent Document 3 includes a float structure disposed below a floating roof that covers the liquid stored in the tank, and an attenuation body that is supported by the float structure and attenuates the flow rate of the liquid. The float structure comprises a flat frame comprising a combination of a plurality of rod-shaped elements, and a cushioning material for preventing damage to the flat frame caused by contact with the floating roof, A sloshing damping device is disclosed in which a cushioning material is molded into a ring shape or a C shape and is externally fitted to the rod-like element.
