Problems solved by technology

However, water jets still use propellers, which are easily entangled by debris, and cannot overcome the phenomenon caused by the "Bernell Principle", and still cannot completely solve the problem of resistance and drag; water jets cannot use longer tubes , so it is impossible to create greater pressure to increase the propulsion efficiency
[0006] Known domestic 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

[0194] Please refer to figure 1 , Is a schematic diagram and a cross-sectional view showing the flow guiding and clustering hollow tube of the fluid jet cluster thruster 100 of the present invention. The inner diameter of the diversion bundled hollow tube 10 is wide in the front and narrow in the rear to enhance the bundling effect in the center of the hollow tube 10 when the fluid passes through, as shown by the dotted line; the tube wall 12 has one or more inner wall diversion tubes Protruding piece 15. In an embodiment of the present invention, the guide fins 15 on the inner wall of the tube are spiral, which are used to generate a spiral cluster fluid at the center of the tube when the flow guide cluster hollow tube 10 is rotated; and on the inner wall of the tube One or more ribs 14 are provided on the surface of the guide tab 15 to strengthen the kink and bundling force when the fluid passes. In another embodiment of the present invention, the guide fins 15 on the inner wal...

Abstract

The invention relates to an ejection fluid beam propeller, which utilizes the screw or straight divert cam or divert groove on the inner wall of tube to increase the fluid friction; therefore, the former loose fluid, via compressed, rotated or extruded, will be twisted to beam shape, to form tube pressure; and the beam fluid will generate high propel force; at the same time, the beam has less air, with less air friction to reduce the noise. The invention can avoid idle corrosion by eliminating the screw propeller. The invention can improve the propel force.

Description

Technical field [0001] The present invention relates to a fluid jet cluster propeller, in particular to a spiral or linear guide fins or guide grooves on the inner wall of the tube to increase the friction of the fluid, making the original loose and loose fluid. When it is pressurized, rotated, or squeezed, it can be twisted into a cluster shape, and the cluster-like fluid can generate a strong propulsion force. 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 spin and slow down the ship. According to the "White Effort Principle", the faster the propeller speed, the lower the water flow pressure, and the water flow will cause vaporization. When the surface pressure of the propeller blades 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 serious bubble bursting...
