The invention discloses a ship underwater resistance reduction device and a ship. The underwater resistance reduction device for the ship is arranged in the ship and located on the side, away from water, of an outer plate of a ship body, and the resistance reduction device comprises a heating module, a control module and an energy supply module; wherein the heating module is arranged on the side, away from water, of a ship body outer plate, the heating module is connected with the control module and the energy supply module, and the energy supply module is connected with the control module; wherein the heating module is used for heating a ship hull plate; the control module is used for controlling the energy supply module to provide energy needed by heating for the heating module. The heating module is arranged on the inner side of the ship body outer plate to heat the ship body outer plate, so that the temperature of water in a boundary layer with a certain thickness on the surface of the ship body outer plate is increased, the viscosity of the water is reduced, and the purpose of reducing frictional resistance is achieved. The drag reduction device is completely located in the ship body, is convenient to install, maintain and maintain, and cannot be affected by marine organism parasitism, erosion and the like.

    本发明公开了一种船舶水下减阻装置和船舶。该船舶水下减阻装置设置在船舶内部,且位于船舶船体外板远离水的一侧,减阻装置包括:加热模块、控制模块和供能模块;其中,加热模块设置在船体外板远离水的一侧,加热模块分别与控制模块和供能模块连接,供能模块与控制模块连接;其中,加热模块用于加热船体外板;控制模块用于控制供能模块给加热模块提供加热所需的能量。通过在船舶船体外板内侧设置加热模块加热船体外板,从而增加船体外板表面一定厚度边界层内水的温度,从而降低水的粘度,达到减小摩擦阻力的目的。该减阻装置完全位于船体内部,便于安装、维护和保养,且不会受到海洋生物寄生和侵蚀等的影响。
