The invention provides a ship depth finder mounting structure capable of reducing noise influence and a ship. A cylindrical structure of the depth finder mounting structure is arranged in a ship bottom deck mounting hole, and the outer wall of the depth finder mounting structure is welded to the ship bottom deck at the mounting hole. The first end of the cylindrical structure is higher than the outer surface of the ship bottom deck, and the second end is located on the inner side of the ship bottom deck. The sensing packaging assembly is arranged in the barrel-shaped structure in a sealed mode, and the end face for sending and/or receiving ultrasonic waves is flush with the end face of the first end of the barrel-shaped structure. A through hole is formed in the fairing, a smooth transition curved surface is formed from the outer edge of the fairing to the edge of the through hole, the fairing is buckled on the ship bottom deck with the protruding side facing outwards, the through hole is sleeved at the first end of the cylindrical structure, the outer edge of the first end of the cylindrical structure is aligned and welded with the edge of the through hole, and the outer edge of the fairing is welded with the ship bottom. A cavity is formed between the flow guide cover and the ship bottom deck, and the sound insulation structure is arranged in the cavity. The flow guide cover can reduce the bubble containing rate of the depth finder and reduce the influence on sound wave propagation, and the sound insulation structure in the flow guide cover can achieve the sound insulation and sound absorption effects.
本申请提供一种能降低噪声影响的船舶测深仪安装结构及船舶,测深仪安装结构的筒状结构设在船底甲板安装孔内,外壁与安装孔处船底甲板焊接。筒状结构第一端高出船底甲板外表面,第二端位于船底甲板内侧。传感封装组件密封置于筒状结构内,发出和/或接收超声波的端面与筒状结构第一端端面平齐。导流罩上开设过孔,其外边缘至过孔边缘为平滑过渡曲面,导流罩以凸起侧朝外扣设在船底甲板,过孔套在筒状结构第一端,筒状结构第一端外边缘与过孔边缘对齐焊接,导流罩外边缘与船底焊接。导流罩与船底甲板之间形成空腔,隔声结构设置在空腔中。本申请中导流罩能减少测深仪处含气泡率,降低对声波传播影响,导流罩中隔声结构能起到隔声和吸音效果。
