Intelligent ship air curtain resistance reducing and energy saving device

Abstract

The invention discloses an intelligent ship air curtain resistance reducing and energy saving device, and relates to the technical field of ship air curtain resistance reduction, the intelligent ship air curtain resistance reducing and energy saving device comprises a ship, upper layer air curtain assemblies and a jet head, a ship tail air curtain assembly is installed behind the bottom of the ship, and a ship head air curtain assembly is installed in front of the bottom of the ship; the upper layer air curtain assemblies are arranged on the upper sides of the ship tail air curtain assembly and the ship head air curtain assembly, the ship tail air curtain assembly comprises a ship tail air pump, a ship tail air injection pipe, a ship tail air valve, a ship tail pressure stabilizing cavity, a ship tail air conveying pipe and a ship tail secondary valve, and one side of the ship tail air pump is connected with the ship tail air injection pipe. According to the intelligent ship air curtain resistance reducing and energy-saving device, the upper-layer air conveying pipe is flatly laid above the ship tail air conveying pipe and the ship head air conveying pipe, the airflow strength can be enhanced by matching with the ship tail air conveying pipe and the ship head air conveying pipe, and the sailing resistance of a ship can be reduced; and the lower parts of the ship tail air conveying pipe and the ship head air conveying pipe can be positioned and fixed with a shockproof effect.

Description

technical field [0001] The invention relates to the technical field of ship air curtain drag reduction, in particular to an intelligent ship air curtain drag reduction and energy saving device. Background technique [0002] The principle of air curtain drag reduction technology is to use the density and viscosity difference between water and air to pass air at the bottom of the ship to form a thin layer of gas-liquid two-phase mixed flow. subject to frictional resistance. Because of its good economic benefits and experimental results, it is the most promising research direction in the field of ship drag reduction. [0003] During the use of the existing air curtain drag reduction and energy saving devices for ships, the drag reduction effect of the air curtain is not good, the strength of the air curtain is weak, and there is no corresponding positioning reinforcement structure under the pipeline to make it easy to damage. Therefore, we propose An intelligent ship air curt...
