Embodiment Construction

[0019] Referring to Figures 1 and 2, the anti-rolling water tank control device includes a U-shaped anti-rolling water tank 1, a port air chamber 11, a starboard air chamber 11', a left throttling assembly 12, a right throttling assembly 12', a detector and a control device.

[0020] U-shaped anti-rolling water tank 1, its structure is similar or the same as that of the prior art, a port air chamber 11 and a starboard air chamber 11' are respectively formed on the two sides of the U-shaped, and are in a sealed state. The tops of 11 and 11' are respectively provided with a left throttling passage 110 and a right throttling passage 110' (such as image 3 , 5 ), the tops of the left and right throttling passages 110, 110' lead to the atmosphere, that is, as image 3 , 5 As shown in the left throttle port 120 and the right throttle port 120', the left throttle assembly 12 and the right throttle assembly 12' can be arranged on the left and right throttle passages 110, 110'.

Abstract

The invention discloses a tank stabilizer control device, which mainly solves the technical problems of improving the pitch damping effects of ships and the like, and adopts the technical scheme that: a left throttling passage and a right throttling passage are arranged at the top parts of a larboard air chamber and a starboard air chamber of a U-shaped tank stabilizer, throttling components are arranged on the two passages, the two components are connected with a controller which is connected with a detector, detected ship swinging period signals are input to the controller, control signals are output to the two throttling components according to set rules, and the throttling components adjust effective sectional areas of the two throttling passages so as to realize the water level alternation period of the U-shaped tank stabilizer the same as the ship swinging period. The tank stabilizer control device is applied to various U-shaped tank stabilizers.

Description

Technical field: [0001] The invention relates to a device for reducing rolling motion of a ship by transferring liquid, and in particular to a control device for the device. Background technique: [0002] The anti-rolling water tank is one of the devices to reduce the roll of the ship. It has the advantages of lower cost than the fin stabilizer and can play a role at any speed (including zero speed). It is widely used in various types of ships above 500 tons. The anti-rolling principle of the boat and the anti-rolling water tank is based on the theoretical analysis results of Krylov-Blagoveshinski. The main point is that due to the small roll damping coefficient of the water tank, the amplification factor The frequency characteristics of the ship show double peaks, which is equivalent to two main harmonic frequencies. If the wave disturbance frequency is near the two main harmonic frequencies, the function of the uncontrolled passive U-shaped water tank is to increase the ro...
