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 .
