The creation is a floating platform height adjusting device, which is arranged on a floating platform and includes a movable adjusting unit and a fixed configuration unit. The movable adjusting unit includes a floating member and at least one adjusting member, and the buoyancy of the floating member is greater than that. The buoyancy of the floating platform. The two ends of each adjusting member are respectively connected to the floating member and the floating platform. The fixed configuration unit is disposed on the movable adjusting unit. The fixed configuration unit includes at least one counterweight. The adjusting members are respectively connected to provide a fixed reference, and the vertical position of the floating platform is adjusted by adjusting the length of the at least one adjusting member, and the floating member can be smoothly positioned through the combination of the floating member and the counterweight. The floating platform height adjusting device can quickly and conveniently adjust the height of the floating platform.本創作係一種浮台高度調整裝置，其係設於一浮台並包含一活動調整單元及一固定配置單元，該活動調整單元包含一漂浮件及至少一調整件，該漂浮件的浮力大於該浮台的浮力，每一調整件的兩端分別連接該漂浮件與該浮台，該固定配置單元係設置於該活動調整單元，該固定配置單元包含至少一配重件，所述配重件分別連接所述調整件並提供一固定基準，以及藉由該至少一調整件的長度調整而調整該浮台的垂直位置，透過該漂浮件與所述配重件的搭配而能順利定位該浮台，讓該浮台高度調整裝置可快速且便利地調整該浮台的高度。
