The invention discloses an amphibious device integrally propelled by a screw in water and land. The amphibious device comprises a machine body and a screw propelling device, the spiral propelling device comprises a spiral cylinder main body, a driving device and a rotary opening and closing device; a first circular opening penetrates through the spiral cylinder body, first spiral blades are arranged on the outer wall of the spiral cylinder body, and second spiral blades are arranged on the inner wall of the spiral cylinder body; the driving devices at the two ends of the spiral cylinder body rotate simultaneously to drive the spiral cylinder body to rotate. During land movement, the rotary opening and closing device is in a closed state, and the solid medium generates shearing force on the first spiral blade, so that the spiral propelling device advances; when moving in water, the rotary opening and closing device is in an open state, and the first spiral blade and the second spiral blade simultaneously poke water flow backwards to obtain forward thrust, so that the spiral propelling device advances. Under the condition that the land performance is not influenced, the underwater movement is improved, and the movement efficiency is improved.

    本发明公开了一种水中陆上一体式螺旋推进的两栖装置,包括机身主体和螺旋推进装置;螺旋推进装置包括螺旋筒主体、驱动装置和旋转开合装置;螺旋筒主体内部贯穿设置第一圆形开口,螺旋筒主体外壁布置第一螺旋叶片,螺旋筒主体内壁布置第二螺旋叶片;所述螺旋筒主体两端的驱动装置同时转动,带动螺旋筒主体旋转;在陆地运动时,旋转开合装置处于关闭状态,固体介质对第一螺旋叶片产生剪切力从而使螺旋推进装置前进;在水中运动时,旋转开合装置处于打开状态,第一螺旋叶片和第二螺旋叶片同时向后拨动水流获得向前的推力,从而使螺旋推进装置前进。本发明在不影响其陆地性能的同时,对其水下运动进行了改进,提高了运动效率。
