Ship inclination test device

Abstract

The invention discloses a ship inclination test device which comprises a water tank, a suspension rod, a pendulum bob, a rope and a plurality of wave absorbers, the water tank is used for containing water, the suspension rod is fixed on the outer wall of the water tank, the pendulum bob is suspended on the suspension rod through the rope and immersed in the water in the water tank, each wave absorber comprises a plurality of blades, and the wave absorbers are arranged on the inner wall of the water tank. At least part of the blades are immersed in water. According to the ship inclination test device, water is adopted to replace heavy oil to immerse the pendulum bob, the difficulty of inclination test preparation work is reduced while pollution is avoided, due to the fact that the viscosity of water is low, water in the water tank is prone to oscillation in the inclination test process, the pendulum bob cannot be stabilized within a long time. According to the ship inclination test device, the wave absorbers are arranged on the inner wall of the water tank, and the blades of the wave absorbers can interact with water to inhibit water oscillation, so that the pendulum bob can be stabilized in a short time, and the efficiency of an inclination test is further improved.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a ship inclination test device. Background technique [0002] A ship is a huge means of transportation composed of various materials and equipment. Due to its complexity and size, there is a certain cumulative deviation in the calculation (estimation) of its weight and center of gravity position during design, and the unavoidable build bias. The addition of the above two results in a certain error between the actual weight and the position of the center of gravity of the ship and the value at the time of design after the ship is completed. Since the weight and height of the center of gravity of the ship have an extremely important relationship with the stability of the ship, after the completion of the ship, an inclination test must be carried out to measure the actual weight and height of the center of gravity of the ship to determine whether the stability of the ship in water is...

Problems solved by technology

However, heavy oil is used to stabilize the pendulum. Due to the unstable wind force on the water surface during the actual test, heavy oil with different viscosities is often required, which increases the difficulty of the test. Moreover, heavy oil has a strong smell, high viscosity, and difficult installation of test equipment, which often pollutes the deck test area.
