Propulsion device of full-circle rotating guide cover type water vehicle

Abstract

The invention discloses a full-cycle rotation guide cover type aquatic carrier propelling device. A prime motor and a pump are used by the device to generate a drive stream in a hull, the drive streamflows through a water inflow guide pipe compounding an inner pipe and an outer pipe and a connecting pipe so as to be divided into an inner drive stream and an outer drive stream, the drive stream isguided into a main stream guide pipe arranged on the outer portion of the hull, and the connecting pipe controls the main stream guide pipe to steer through a power source. A primary drainage inner nozzle, an intermediate stream guide nozzle and a secondary drainage outer annular nozzle are arranged in the main stream guide pipe and combined from inside to outside. The primary drainage inner nozzle is linked to the inner pipe and can guide the inner drive stream inside. The secondary drainage outer annular nozzle is linked to the outer pipe and can guide the outer drive stream inside. High-speed streams are formed in the center and on the circumferential side of the main stream guide pipe through the inner drive stream and the outer drive stream correspondingly, one main stream can be pulled and drained to flow through the intermediate stream guide nozzle to increase the flow speed, the total water flow of water flowing through the main stream guide pipe is increased, and therefore thrust driving the hull to move at the accelerated speed is generated.

Description

technical field [0001] The invention relates to a propulsion device for a full-circle rotating guide cover type water vehicle, in particular to an environment-friendly propulsion device that can avoid contact with foreign objects in water and has improved propulsion efficiency and low noise. Background technique [0002] Most of the traditional water vehicles (ships) use propellers as the main drive components. It is more common to arrange the propellers below the horizontal plane behind the hull (hull), and set a piece of rudder on the rudder driven by the propellers. On the water flow path, so as to achieve the purpose of driving the water vehicle (ship) to move and control the direction; but in practical applications, the above-mentioned propeller is set outside the hull (hull) and directly contacts with the external water, and drives The internal combustion engine (engine) of the propeller must be arranged on the water surface in or above the hull (hull), so as the hull ...

Problems solved by technology

[0006] Another technical problem to be solved by the present invention is to provide a kind of propulsion device for a full-circle rotating guide hood type water vehicle, which is to arrange the prime mover and the pump inside the hull for the water introduced outside the hull to form the driving water flow, so The noise diffused outside the hull and in the water will be reduced, which can effectively reduce the influence and pollution of the underwater environment by noise, and it can facilitate the sound insulation processing of the prime mover and pump and other noise sources according to needs, so that it can obtain better Mute effect, in response to special occasions
