Description

Full-circle rotating guide type water uploader propulsion device

The invention relates to a full-circle rotating guide type water-loading device propulsion device, in particular to an environmentally-friendly propulsion device capable of avoiding foreign matter touching water and having improved propulsion efficiency and low noise.

Conventional water carriers (ships) mostly use propellers as the main driving components. The more common ones are to place the propellers below the water level behind the hull (hull) and to place a piece of rudder on the propeller. In the water flow path, the purpose of driving the water carrier (ship) to move and control the direction is achieved; but in practical applications, the propeller is disposed outside the hull (hull) and directly contacts the external water. The internal combustion engine (engine) that drives the propeller must be placed on the water surface in or above the hull (hull), so that the larger the hull (hull), the transmission of the propeller by the internal combustion engine (engine) The longer the path of the shaft is extended, the undesired deflection of the center of the transmission shaft often causes vibration and various resonance situations during operation. In addition to causing power loss and affecting the efficiency of power transmission, it will also be serious. It affects the stability during navigation; in addition, the above-mentioned propeller that directly protrudes into the water will generate a lot of noise when it is rotated, which will not only damage the quietness of the environment, but also be difficult to It is used for special (military) silent sneak and other occasions, and the propeller is also easy to touch foreign objects in the water during navigation (eg fishing nets, cables) It causes a fault condition and makes the aquatic organism vulnerable or damaged by aquatic organisms, forming various defects in the application.

The force of the propulsion is formed on the passage wall and the hull (hull).

However, such a device generates a driving force due to the fact that the propeller directly acts on the water flow outside the hull, so it is strictly a change in the application of the aforementioned conventional propeller, although the impeller (propeller) and the guide vane are disposed on the The design of the suction casing, the pump casing, and the inside of the discharge casing can reduce the chance of damage caused by touching foreign objects or aquatic organisms under the water, but it is still difficult to completely avoid; and it cannot overcome the application of noise-damaged environment.
