The invention relates to the technical field of ships, in particular to a double-layer ship bottom plate which comprises an outer bottom plate body, the outer bottom plate body comprises a horizontalsection and a vertical section, a bent circular bead is arranged between the horizontal section and the vertical section, the horizontal section, the bent circular bead and the vertical section are ofan integrated structure, and an inner bottom plate body is connected to the inner side face of the vertical section. The inner bottom plate comprises a connecting surface section, an inclined surfacesection and a horizontal surface section, the inner bottom plate is connected with the outer bottom plate through the connecting surface section, the outer surface of the outer bottom plate is coatedwith a corrosion-resistant coating, and the corrosion-resistant coating is filled with a plurality of wear-resistant particles; the double-layer ship bottom plate is simple in structure and reasonable in design, the inner bottom plate body and the outer bottom plate body are connected through the connecting face sections, connection is more stable, the corrosion-resistant strength of the ship bottom plate is improved through the corrosion-resistant coating, the service life of the ship bottom plate is prolonged, and the friction-resistant strength of the ship bottom plate is improved throughthe wear-resistant particles; sharp substances in a water body are prevented from scraping the surface of the ship bottom plate to influence the corrosion resistance of the ship bottom plate.

    本发明涉及船舶技术领域,尤其是一种双层船底板,包括外底板,所述外底板包括水平段和竖直段,水平段和竖直段之间有一个弯折圆角,所述水平段、弯折圆角和竖直段为一体结构,所述竖直段的内侧面上连接有内底板,所述内底板包括连接面段、倾斜面段和水平面段,内底板通过连接面段与外底板连接,所述外底板的外表面涂覆有耐腐蚀涂层,所述耐腐蚀涂层内填充有若干耐磨颗粒;本发明中双层船底板,结构简单,设计合理,内底板和外底板之间通过连接面段连接,连接更稳定,耐腐蚀涂层提高了船底板的耐腐蚀性强度,延长了船底板的使用寿命,耐磨颗粒提高了船底板的耐摩擦强度,避免水体中的锋利物质在船底板表面刮擦,影响船底板的耐腐蚀性。
