The invention relates to the technical field of ships, and discloses a watertight protection device for a measuring instrument. The watertight protection device comprises a watertight door, a measuring cabin and a control system, an opening is formed in the bottom of the measuring cabin, the watertight door is installed in the measuring cabin and can open or seal the opening, an inflation assembly is arranged on the measuring cabin, and the inflation assembly is used for being communicated with an external air source so as to provide compressed air into the measuring cabin, so that the internal air pressure of the measuring cabin is higher than the external air pressure of the measuring cabin; the control system is electrically connected with the watertight door, and the control system is configured to obtain a measurement work instruction and control the watertight door to open the opening when the internal air pressure of the measurement cabin is greater than the external air pressure. The measuring instrument can be fixedly installed at the bottom of the ship, the detection probe extends out to achieve the purpose of measurement and investigation, and water outside the measuring cabin cannot enter the measuring cabin.

    本发明涉及船舶技术领域,公开了一种用于测量仪的水密防护装置包括水密门、测量舱和控制系统;测量舱的底部开设有开口,水密门安装于测量舱,且能够打开或密封开口,测量舱上设有充气组件,充气组件用于与外部气源连通,以向测量舱内提供压缩气体,让测量舱的内部气压高于测量舱的外部气压;控制系统与水密门电连接,控制系统被配置为:获取测量工作指令,当测量舱的内部气压大于外部气压时,控制水密门打开开口。能够实现船底固定安装测量仪,伸出探测探头实现测量考察的目的,且测量舱外的水不会进入测量舱内。
