The invention provides an underwater positioning device for marine surveying and mapping, and relates to the field of underwater surveying and mapping, the underwater positioning device comprises a first shell, the bottom of the first shell is provided with a counterweight mechanism, the top of the first shell is provided with a mounting plate, the top of the mounting plate is fixedly connected with a fixed seat, and the fixed seat is provided with a protective cover; a closed inner cavity is defined by the protective cover and the fixing base, a mounting base is arranged in the closed inner cavity of the fixing base, and a sinking and floating mechanism used for floating the mounting plate is arranged in the first shell. According to the underwater positioning device for marine surveying and mapping, through the arrangement of the sinking and floating mechanism, when an instrument needs to be debugged after sedimentation, a motor is started, the motor rotates to loosen a traction rope, and then a valve corresponding to the uppermost air bag is opened, so that gas in a compressed gas cylinder is inflated into the uppermost air bag; when the air bag expands and becomes larger, the mounting plate is jacked up until the air bag expands until the buoyancy is larger than the gravity of all instruments on the mounting plate.

    本发明提供一种海洋测绘的水下定位装置,涉及水下测绘领域,包括第一壳体,所述第一壳体的底部设置有配重机构,所述第一壳体的顶部设置有安装板,所述安装板的顶部固定连接有固定座,所述固定座上安装有防护罩,所述防护罩与固定座围合形成封闭内腔,所述固定座在封闭内腔内设置有安装座,所述第一壳体内设置有用于将安装板浮起的沉浮机构。该海洋测绘的水下定位装置,通过沉浮机构的设置,当在沉降后需要对仪器进行调试时,开启电机,电机转动使得牵引绳松开,然后开启最上面一个气囊所对应的阀门,使得压缩气瓶内的气体充入最上面的气囊内,气囊膨胀变大的同时将安装板向上顶起,直至气囊膨胀至浮力大于安装板上所有仪器的重力后。
