Controllable passive stabilization water tank

Abstract

The invention relates to a naval vessel part, in particular to an adjustable passive stabilization water tank. The adjustable passive stabilization water tank includes U-shaped cabins, the left and right sides of the U-shaped cabins are wing tanks, a cabin between the two wing tanks is a lower cabin, and damping blocking plates are arranged in the lower cabin. The adjustable passive stabilizationwater tank is characterized in that control boxes are connected on the cabins, liquid level sensors are arranged in the two wing cabins, decompression valves are arranged on the two wing cabins, and the liquid level sensors and the decompression valves are both electrically connected with the control boxes. The adjustable passive stabilization water tank is low in energy consumption and long in service life, and the uniformity of the liquid level height of the left and right wing cabins can be maintained, and the safety of vessels during sailing can be improved.

Description

technical field [0001] The invention relates to a ship component, in particular to a controllable passive anti-rolling water tank. Background technique [0002] Chinese patent ZL200820150739.0 relates to an anti-rolling water tank control device, such as figure 1 As shown, air butterfly valves 2 are respectively installed on the tops of the left and right wing tanks 1 of the U-shaped anti-rolling water tank, directly connected to the external atmosphere, and the flow of liquid in the cabin is adjusted by opening and closing the air butterfly valves 2, so as to match the ship's roll to achieve the purpose of reducing ship roll. However, when the air butterfly valve 2 is used to adjust the water flow oscillation period of the anti-rolling water tank, it needs to be opened and closed frequently, which consumes a lot of energy, is easy to be damaged, and has a short service life. Moreover, when the anti-rolling water tank is not working, the air butterfly valve 2 is closed. At...

Problems solved by technology

However, when the air butterfly valve 2 is used to adjust the water flow oscillation cycle of the anti-rolling tank, it needs to be opened and closed frequently, which consumes a lot of energy, is easy to be damaged, and has a short service life.

Moreover, when the anti-rolling water tank is not working, the air butterfly valve 2 is closed. At this time, if the liquid levels of the left and right wing tanks 1 are inconsistent, it will increase the ship's roll and affect the safety of the ship's navigation.

If the air butterfly valve 2 is opened to balance the water level in the wing tank 1 when the anti-rolling water tank is not working, it will increase the roll of the ship, and because the air butterfly valve 2 has a large diameter, the water flow speed is fast at this time, and it is difficult to accurately Make sure that the liquid level of the left and right wing tanks 1 is the same

At the same time, setting the air butterfly valve 2 on the top will also increase the height of the anti-roll tank and increase the occupied space
