A marine breathing power device

Abstract

The invention discloses a breathing-type propulsion device for a ship. The breathing-type propulsion device comprises a burning chamber (7), a water storing chamber (8), a water insulation floater (10) and a guiding pipe (9). The burning chamber (7) is provided with a first air exchanging valve (1), a second air exchanging valve (2), a nozzle (5) and a sparking plug (6), and an air hole is formed in the bottom of the burning chamber (7); the water storing chamber (8) is in fluid breakover connection with the burning chamber (7) through the air hole; the water insulation floater (10) is limited at the internal top of the water storing chamber (8) through a floater support (11) and can movably seal the air hole; and the guiding pipe (9) and the bottom of the water storing chamber (8) are connected in an inverted T shape, and the guiding pipe (9) is in fluid breakover with the water storing chamber (8) and is provided with a front opening section and a rear opening section, wherein a one-way water inlet valve (3) is arranged in the front opening section. The breathing-type propulsion device is simple in structure, capable of more sufficiently utilizing fuel and greatly increasing the fuel utilization ratio and good in thrust continuity.

Description

technical field [0001] The invention belongs to the technical field of ship application, in particular to a marine breathing power device. Background technique [0002] The navigation of ships requires power, and the commonly used power devices are realized by paddle wheels, propellers and water jets. The paddle wheel and the propeller are directly driven by pushing water backwards in a rotating manner. The paddle wheel method is inefficient in the front and rear directions because a part of the thrust is consumed in the up and down direction. The propeller is improved compared with the paddle wheel, but the propeller speed is too high At this time, the cavitation effect will be generated near the propeller blade. At this time, the propeller is equivalent to pushing the gas first and then the water, which also leads to a decrease in propulsion efficiency. However, the existing water spraying methods are often realized by driving the water pump with traditional rotary power....

Problems solved by technology

The paddle wheel and the propeller are directly driven by pushing water backwards in a rotating manner. The paddle wheel method is inefficient in the front and rear directions because a part of the thrust is consumed in the up and down direction. The propeller is improved compared with the paddle wheel, but the propeller speed is too high At this time, a cavitation effect will be generated near the propeller blade. At this time, the propeller is equivalent to pushing the gas first and then the water, which also leads to a decrease in propulsion efficiency.

However, the existing water spraying methods are often realized by driving the water pump with traditional rotary power. In these processes, there is inevitably a link of power loss, and the efficiency is not high.
