Marine water spraying type propeller

Abstract

A marine water spraying type propeller comprises a water spraying pipe body, a water inlet valve, backward water inlet pipes, a hydro-generator impeller wheel, an electric water spraying machine, backward water spraying pipes and a water outlet valve. The marine water spraying type propeller is characterized in that at least one cylindrical water spraying pipe is arranged on the outer wall, on the bottom of a ship, of a ship body, one end of the cylindrical water spraying pipe is provided with a water inlet, the other end of the cylindrical water spraying pipe is provided with a water spraying opening, the water inlet valve and water wheel blades of a hydroelectric generator are arranged in the pipe wall, close to the end provided with the water inlet, of the water spraying pipe, the water outlet valve and the electric water spraying machine are arranged in sequence in the water spraying pipe close to the end provided with the water spraying opening, the electric water spraying machine is fixed on the pipe wall of the water spraying pipe through a stand, and a closed blade water wheel is arranged in the pipe opening of the water spraying machine. The marine water spraying type propeller does not use a screw propeller for spraying, but uses hydraulic pressure for spraying, and is assisted by the rotation of the water wheel blades. Driving at high speed can be achieved, and noise can be reduced. The propeller is suitable for various ships and particularly suitable for a warship and a submarine, and quickness and sound concealing effects can be achieved.

Description

technical field [0001] The invention relates to a propeller, in particular to a marine water jet propeller. Background technique [0002] As we all know, at present, all kinds of motorized ships including cargo ships, passenger ships, warships and submarines are driven by electric motors to rotate propellers to push the ships forward. The larger the tonnage of the ships, the greater the output power of the engines driving the propellers The more oil, coal or electricity, this kind of ship propelled by propellers has loud noise, slow speed, and high energy consumption are the biggest defects during navigation. This defect restricts the development of the entire shipbuilding industry and also affects my country's shipping industry. Some ships, including warships, need fast speed and energy saving, especially submarines require low noise and fast speed. For this, the majority of ship production and scientific and technological workers are eager to have a kind of energy-saving and...

This defect restricts the development of the entire shipbuilding industry and also affects my country's shipping industry. Some ships, including warships, require fast speed and energy saving, especially submarines require low noise and fast speed. For this, the majority of ship production and scientific and technological workers are eager to have a kind of energy-saving and energy-saving The advent of ship propellers with low noise and high speed to meet the needs of the growing ocean transportation industry and naval construction
