Problems solved by technology

[0006] It is known that Chinese Taiwan patents 572842, 547573, 528699, 339756, and U.S. patents US005181868A and US005083435A all construct propellers with different functions with different ingenuity, but because propellers are still used, the problems of the above-mentioned known technologies cannot be solved

Embodiment Construction

[0103] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments, but not as a limitation of the present invention.

[0104] figure 1 It is a schematic diagram of the self-inflatable jet propeller of the present invention. The jet propeller 210 of the present invention comprises: a first flow guide structure for pressurizing a fluid in a tube; a roller type guide tube 220 with a second flow guide structure in the roll type guide tube 220 , used to repressurize the fluid in the tube after the first flow guide structure is pressurized; and a transmission shaft 240, used to drive the first flow guide structure and the second flow guide structure to rotate, so that the fluid in the tube passes through The first guide structure and the roller guide tube 220 rotate to pressurize the fluid in the tube and form the pressure inside the tube to generate propulsion.

[0105] As shown in the figure, the jet propulsion ...

Abstract

The invention provides a jet propeller which can inflate by itself and an outboard engine device with the jet propeller that can inflate by itself. In addition to the propelling function, a nozzle device with special functions can be jointed to achive functions such as air inflation, air extraction, using as a spray gun, high-pressure water spray (for fire protection or cleaning), warer pumping, and the like with the same device. The jet propeller of the invention does not use general screw propeller blades, so damage to human bodies or organisms in the sea, or collision or entanglement with foreign bodies in the water are not easy to occur; and the jet propeller is an integrated, multifunctional, safe and enviromental friendly propeller.

Description

technical field [0001] The present invention relates to a jet propeller and an outboard motor device with the jet propeller, in particular to a self-inflatable jet propeller and an outboard motor device with the self-inflatable jet propeller . Background technique [0002] The ship is propelled by the engine and the propeller, but the cavitation phenomenon of the propeller often causes the propeller to idle and slow down the ship. According to the "Bernell Principle", the faster the propeller rotates, the lower the pressure of the water flow, and the water flow will also vaporize. When the surface pressure of the propeller blade is lower than the seawater vapor pressure, the phenomenon of "propeller cavitation" will occur. Air bubbles are the main cause of ship vibration and noise, and severe air bubble rupture will cause the efficiency of the propeller to decrease, the propeller to idle and slow down the speed of the ship, and even cause the propeller blades to produce pit...
