PRESSURE BALANCE TYPE FLOATING BODY AND MOUNTING METHOD THEREOF

摘要

An underwater pressure balance type floating body and a mounting method. The floating body comprises water cabins (1), air cabins (2), air cabin inflation valves, an underwater pressure equalizing control system, water cabin water passing systems, and water cabin permeable systems. The interior of the floating body is divided into water cabins (1) and air cabins (2), each water cabin (1) is provided with a water cabin water passing system and a water cabin permeable system, and each air cabin (2) is provided with an air cabin inflation valve, and the air cabin inflation valve is connected to the underwater pressure equalizing control system. The buoyancy center and the gravity center of the floating body are in a same vertical line, and the buoyancy center is higher than the gravity center. The method comprises: filling water into the water cabin (1), lowering a main body of the floating body into the water and immersing the main body in the water; pulling the main body of the floating body downwards, controlling the air pressure in each air cabin (2) to be consistent with the external water pressure; and inflating each water cabin (1), and discharging water in the water cabin (1), so as to provide upward buoyancy. According to the underwater floating body and the mounting method in the present invention, the underwater floating body can arrive at a working water area for one time, so that a large number of manpower and material resources are saved.
