Energy-saving ship thruster

Abstract

The invention discloses an energy-saving ship thruster, comprising a motor (1), a propeller (2) and a connecting rod (3), wherein the motor (1) and the propeller (2) are connected by a retarding mechanism (4); a beam ring (5) covers the propeller (2); a protective cover (6) is arranged at the opening of the beam ring (5); the motor (1) is a water generator. The speed of the energy-saving ship thruster is easy to control, the thrusting efficiency is high, and the propeller is difficult to damage.

Description

technical field [0001] The invention relates to ship equipment, in particular to an energy-saving ship propeller. Background technique [0002] Most of the early energy-saving ship propellers used gasoline internal combustion engines as power to drive propellers. This kind of propeller consumes a lot of fuel, emits a lot of carbon dioxide, and is easy to cause pollution. noise. For above-mentioned deficiency, people have invented a kind of propeller, and it is installed in exhaust device under the water surface, but a large amount of tail gas discharges into water, has had a strong impact on water quality. [0003] At present, with the enhancement of people's awareness of environmental protection, energy-saving ship propellers basically use batteries as energy sources, and propellers are driven by motors to pull ships. However, such propellers connect the output shaft of the motor directly to the propeller, making it difficult to control the low speed of the ship. Moving f...

Problems solved by technology

[0002] Most of the early energy-saving ship propellers used gasoline internal combustion engines as power to drive propellers. This kind of propeller consumes a lot of fuel, emits a lot of carbon dioxide, and is easy to cause pollution. noise

Aiming at the above-mentioned deficiencies, people have invented a propeller, which installs the exhaust device under the water surface, but a large amount of exhaust gas is discharged into the water, which seriously affects the water quality

[0003] At present, with the enhancement of people's awareness of environmental protection, energy-saving ship propellers basically use batteries as energy sources, and propellers are driven by motors to pull ships. However, such propellers connect the output shaft of the motor directly to the propeller, making it difficult to control the low speed of the ship. Moving forward, and when the propeller of this propeller rotates, the propelled water flow will diverge along the direction of the propeller shaft, which greatly reduces the reaction force and makes the propulsion efficiency lower

However, there are many sundries such as aquatic plants in the water. When the propeller rotates, it is easy to be entangled or stuck, causing damage to the propeller.
