Problems solved by technology

[0004] In order to overcome the disadvantages that the existing propellers are directly connected by the hub and the blades and cannot achieve the purpose of energy saving, even if the length of the blades can be increased, but at the same time the area of ​​the blades is too large and the running resistance is also large, the present invention proposes A kind of edge propeller was developed to solve this problem, and the purpose of energy saving can be achieved without increasing the running resistance of the blade

Embodiment Construction

[0011] exist figure 1 In the embodiment, we further illustrate the present invention by implementing a kind of edge propeller as example:

[0012] figure 1 It is a structural schematic diagram of an edge propeller of the present invention. In the figure, the propeller hub 1 is the center of the propeller and is connected with the rotating shaft. It is similar to the propeller hub of an ordinary propeller and is generally made of metal materials; the propeller shaft 2 has enough Strong metal rod, its length and diameter are determined according to specific needs. Under the condition of satisfying the strength, the smaller the diameter, the better; the blade 3 is the main body that generates thrust, connected to the end of the blade rod 2, and the blade can be a spiral shape or an approximately flat metal plate installed at an angle. Its specific size depends on the occasion of use. Since the blade 3 is located on the edge of the rotating surface, away from the center of t...

Abstract

An edge rotating paddle comprises a paddle hub, a paddle rod and a paddle vane. The paddle rod is connected between the paddle hub and the paddle vane. The paddle hub and the paddle vane are connected through the paddle rod, so that wiped fluid area is increased when the paddle vane with the same area rotates by a circle, and accordingly under the situation that pushing force is not changed, pushed fluid mass is increased, pushed fluid speed is decreased, and therefore the purpose of energy saving is achieved. The edge rotating paddle can be used as a pushing device for a steamship, a warship, an aircraft carrier and the like traveling on deep rivers, lakes and sea.

Description

[0001] Technical field [0002] The present invention relates to a propeller, that is, a rotating blade, especially an edge propeller in which the blades are distributed near the circumference by a blade shaft. Background technique [0003] Propeller refers to a device that converts the rotational power of the engine into propulsion by rotating the blades in the air or water. There may be two or more blades connected to the hub, and the rear side of the blades is a helical surface or similar to A marine propeller with a helicoid. There are many kinds of propellers, which are widely used, such as propellers of aircraft and ships, etc. However, due to the structure of the current propellers, this structure is not ideal for situations that require large thrust and want to reduce resistance and save energy. Because according to the law of conservation of momentum, when the thrust requirement is constant, the smaller the diameter of the propeller, the higher the speed requiremen...
