The invention discloses a corrosion-resistant pressure stabilizing cavity structure suitable for an air layer drag reduction ship, and relates to the technical field of ship energy conservation and drag reduction. The pressure stabilizing cavity comprises multiple PE pipes and a base plate, the multiple PE pipes extend in the width direction of the ship body, and the multiple PE pipes are distributed in parallel in the length direction of the ship body at intervals and penetrate through longitudinal ribs of the ship; the PE pipe is provided with a first opening, the first opening extends in the width direction of the ship body, and the two sides, in the width direction of the first opening, of the PE pipe are connected with the ship bottom plate to form a pressure stabilizing cavity; the base plate extends in the width direction of the ship body, is made of a corrosion-resistant material and is located between the PE pipe and the ship bottom plate, and the base plate is in sealed connection with the PE pipe and the ship bottom plate; a first through hole is formed in the base plate, a second through hole communicated with the first through hole is formed in the ship bottom plate, and the pressure stabilizing cavity is communicated with the outside of the ship body through the first through hole and the second through hole. The pressure stabilizing cavity is made of a PE material, so that the corrosion-resistant effect is better; and the base plate made of the corrosion-resistant material also reduces the corrosion of the ship bottom plate.
本发明公开了一种适用于气层减阻船舶的耐腐蚀稳压腔结构,涉及船舶节能减阻技术领域。该稳压腔包括PE管和垫板,PE管为多个且均沿船体的宽度方向延伸,多个PE管沿船体的长度方向平行且间隔分布且均穿设于船舶的纵骨;PE管设置有第一开口且第一开口沿船体的宽度方向延伸,PE管在第一开口宽度方向的两侧均与船底板连接以形成稳压腔;垫板沿船体的宽度方向延伸且为耐腐蚀材质并位于PE管和船底板之间,垫板与PE管密封连接且与船底板密封连接;垫板上设置有第一通孔,船底板设置有与第一通孔连通的第二通孔,稳压腔通过第一通孔和第二通孔与船体外部连通。该稳压腔为PE材质,耐腐蚀效果更好;耐腐蚀材质的垫板也减少了船底板的腐蚀。
