Low speed fin stabilizer for sand carrier

A technology for stabilizing fins and transporting sand ships, which is applied to equipment that reduces ship motion, equipment that increases the stability of ships, and uses hydrofoils to act on the surrounding water surface to reduce ship motion and other directions. Insufficient ship stability, good effect and other problems, to achieve the effect of light weight, simple structure and low cost

Problems solved by technology

As a result, the stability of the sand carrier is insufficient during navigation, and it is very easy to capsize due to insufficient stability during heavy rain, strong wind and waves, or large ships.
Therefore, it is of great significance to add fin stabilizers to sand carriers to improve their stability. However, most of the stabilizers currently used are effective at high speeds and cannot meet the needs of sand carriers. Therefore, we have designed and invented a Low speed fin stabilizer for sand carrier

Embodiment 1

[0014] As shown in the figure, a low-speed fin stabilizer for sand transport ships is characterized in that it includes a fin stabilizer 1, a fin shaft 2 and a servo system 3. The fin stabilizer 1 is narrow in front and wide in a trapezoidal shape. The fin shaft 2 is arranged on the leading edge of the fin stabilizer 1, and the fin shaft 2 is connected with the servo system 3 arranged in the ship so that the servo system 3 controls the movement of the fin stabilizer 1.

[0015] The working principle of the present invention is as follows: because the hull structure of sand transport ship is simple, the equipment is simple and crude, for this reason designed simple servo control process for sand transport ship (please participate figure 2 ). When the ship is in wavy sea conditions, the driver grasps the ship's rolling situation through the ship's roll gauge, and then controls and adjusts the fin angle and angular velocity of the low-speed stabilizer fin 1 through the manipulat...

Abstract

Disclosed is a low speed fin stabilizer for a sand carrier. The low speed fin stabilizer for the sand carrier comprises fin stabilizers, fin shafts, and servo systems; and each fin stabilizers forms afront-narrow rear-wide trapezoid, the fin shafts are arranged at the leading edge of the fin stabilizers, and fin shafts are connected with the servo systems in the sand carrier to enable the servo systems to control the fin stabilizers to move. The low speed fin stabilizer for the sand carrier has the beneficial effects that the fin stabilizers are applied on the sand carrier, the stability of the sand carrier is enhanced, the fin stabilizers can work at a high speed and at a low speed or at zero speed, full speed reduction is achieved, and the fin stabilizers take up less space inside of aship; and the structure is simple, the volume is small, the weight is light, and the cost is low.

Description

technical field [0001] The invention relates to a low-speed stabilizer fin used for a sand carrier, and belongs to the field of ship engineering. Background technique [0002] Fin stabilizer is currently the most effective anti-rolling device. It is installed in the bilge of the two sides of the ship. Force, thereby forming the anti-rolling moment, reducing the sway, so as to reduce the roll of the hull. The structure of this equipment is complex, the cost is high, and the effect depends on the speed. The higher the speed, the better the effect, so it is mostly used in high-speed ships. It has two series: retractable fin stabilizer and non-retractable fin stabilizer. Vessels equipped with fin stabilizers. It can improve the safety of the ship, improve the seaworthiness of the ship; improve the working conditions on board, improve the work efficiency of the crew; avoid cargo collision and damage; increase the speed of the ship in wind and waves, save fuel, and prolong the s...
