The invention relates to the technical field of ships, in particular to a hatch cover for a ship. The hatch cover comprises a heat insulation cover body used for sealing a hatch, a heat conduction ring seat is fixedly arranged at the edge of the lower side face of the heat insulation cover body and provided with an annular groove with a downward opening, and an annular sealing ring is arranged in the annular groove and provided with a sealing face used for being in sealing fit with an annular protrusion at the hatch. The heat conduction ring base is provided with a heating piece used for heating the heat conduction ring base. The heat insulation cover plate can insulate most of outside heat, the problem that the temperature in a cabin is too high due to direct sunlight is solved, the heat insulation cover plate has a heat insulation function, heat insulation materials do not need to be arranged, the size and weight of the heat insulation cover plate are reduced, and light weight of the hatch cover is facilitated. In addition, due to the fact that the heat conduction performance of the heat insulation cover plate is poor, heat generated by the heating piece is directionally conducted to the icing area, heat dispersion is reduced, and the deicing efficiency is improved.

    本发明涉及船舶技术领域,特别涉及一种船用舱口盖。舱口盖包括用于封盖舱口的隔热盖体,隔热盖体的下侧面边缘处固设有导热环座,导热环座具有开口朝下的环形凹槽,环形凹槽内设有环形密封圈,环形密封圈具有用于与舱口处的环形凸起密封配合的密封面;导热环座上设有用于对导热环座进行加热的加热件。隔热盖板能够隔绝外界的大部分热量,避免阳光直射引起的舱室内温度过高的问题,而且由于隔热盖板本身具有隔热功能,不用再设置隔热材料,减小了隔热盖板的尺寸和重量,有利于舱口盖的轻量化;此外,由于隔热盖板的导热性能差,使得加热件产生的热量定向往结冰区传导,降低了热量的分散,提高了除冰效率。
