Embodiment 1

[0022] See Figure 1 to image 3 As shown, a ship speed-up and low-consumption device of the present invention includes a hull 1, a propulsion propeller 2 arranged at the stern of the hull 1 and a power shaft 3 linked with the propulsion propeller 2, and the propulsion propeller 2 is fixed on the rear end of the power shaft 3 , a guide body 4 is provided on the periphery of the propulsion propeller 2, and the shape of the guide body 4 is an elliptical cone with a large front and a small rear, and its major axis is in the horizontal direction; 41. The front side of the through hole 41 expands to both sides; the upper part of the guide body 4 is fixedly connected with the hull 1, and the hull 1 is provided with a front through-hole propeller rudder or double rear rudders. The front through-hole propeller rudder has been fully disclosed in Chinese patent CN02227895.8, so it will not be described here.

Embodiment 2

[0024] See Figure 1, Figure 4 , Figure 5 As shown, a ship speed-up and low-consumption device of the present invention includes a hull 1, a propulsion propeller 2 arranged at the stern of the hull 1 and a power shaft 3 linked with the propulsion propeller 2, and a guide body 4 is arranged on the periphery of the propulsion propeller 2 , the shape of the guide body 4 is an elliptical cone with a large front and a small rear, and its major axis is located in the horizontal direction; a through hole 41 adapted to the propulsion propeller 2 is provided in the middle of the guide body 4, and the front side of the through hole 41 is on both sides. Expansion; the upper part of the guide body 4 is fixedly connected with the hull 1, an outer ring 20 is provided on the outer edge of the propulsion propeller 2, a bracket 5 is provided in the through hole 41 of the guide body 4, and a positioning shaft 6 is provided at the middle part of the bracket 5, and the positioning shaft 6 is fi...

Embodiment 3

[0026] See Figure 1, Figure 6 , Figure 7 As shown, a speed-increasing and low-consumption device for a ship of the present invention is basically the same as Embodiment 2, except that two propulsion propellers 2 are provided at the stern of the ship. The transmission gear 31 is respectively linked with the transmission teeth 21 of the outer rings 20 of the propellers 2 on both sides through the two distribution gears 8 .

Abstract

An accelerator with low energy consumption for ship is composed of a propeller, a power axle for driving said propeller and a flow guiding truncated conic barrel surrounding said propeller. It can eliminate the turbulent flow and eddy to increase speed and stability of ship.

Description

technical field [0001] The invention relates to a ship technology, in particular to a ship speed-up and low-consumption device. Background technique [0002] The traditional ship propulsion propeller will generate turbulence and vortex when propelling, which increases the resistance and stability of the ship's navigation, and at the same time increases energy consumption and operating costs. There is still no good solution to this technical problem. solution. After many years of observation and research, the applicant of the present invention has now proposed a solution that can solve this technical problem. Contents of the invention [0003] The object of the present invention is to address the deficiencies of the prior art, and provide a speed-increasing and low-consumption device for ships that has a simple structure, is easy to install, can eliminate turbulence and vortices in ships, and improves ship navigation stability. [0004] The object of the present invention...
