Rotary wing type full speed vector ship stabilizer

Abstract

The invention relates to a telescopic stabilizer for a hull. The telescopic stabilizer is fixedly arranged on the hull, and comprises a stabilizer body and a stabilizer telescopic device, wherein thestabilizer telescopic device is fixedly arranged on the hull, and the stabilizer body is slidably arranged on the stabilizer telescoping device; the stabilizer telescoping device comprises a stabilizer mounting barrel and a telescopic assembly, wherein the stabilizer mounting barrel is fixedly mounted on the hull, and the stabilizer body is slidably arranged in the stabilizer mounting barrel; andone end of the telescopic assembly is fixedly connected with the stabilizer mounting barrel, and the other end of the telescopic assembly is fixedly connected with the stabilizer body. The stabilizercan produce no resistance when a ship is stabilizing at different speed, and the auxiliary pushing force can even be generated if needed; and the stabilizer can be stored in the hull under the sea condition without wind and waves so as to reduce the sailing resistance of the ship, and the service life of the stabilizer can be effectively prolonged.

Description

technical field [0001] The invention relates to a ship anti-rolling device, in particular to a rotor type full speed vector ship anti-rolling device. Background technique [0002] Ships sailing in wind and waves will produce various sway, and the most influential ones are roll, pitch and heave. The swaying of the ship will increase the navigation resistance and reduce the efficiency of the propeller. It will also affect the use of weapons and equipment on board, cause fatigue, seasickness and even loss of combat effectiveness. In order to reduce the sway of the ship, the ship is generally equipped with an anti-rolling device. At present, the ship anti-rolling devices adopted in the world mainly include bilge keels, fin stabilizers, and anti-roll water tanks, and some small ships also use a kind of gyro stabilizer. [0003] The application number is CN201110211329.9, and the patent name is dynamic ship stabilizer. It discloses that the prime mover drives the main shaft to r...

AI Technical Summary

Problems solved by technology

The present invention is installed in pairs on the bilge of the ship, and by controlling the direction of the force, it can generate a righting moment against the ship's roll, thereby achieving the purpose of reducing the roll; when the above-mentioned stabilizer is installed on the ship, the paddle The blade is directly exposed to the water flow, resulting in great resistance during navigation, which greatly reduces the speed of the ship, increases the energy required for the ship to sail, and causes a waste of resources. At the same time, the blade is exposed to the water flow for a long time. The propeller shaft is subjected to a large external force for a long time, which is easy to cause the propeller shaft to bend and break, which makes the stabilizer unable to work normally and greatly reduces the service life of the stabilizer
