Problems solved by technology

[0002] Paddle steamers, which flourished in the era of steam engines, are low-speed and low-efficiency ship types, which have long been eliminated by propeller ships. This is the consensus of those skilled in the art; There are mainly propeller types; when sailing at high speed, planing boats and hydrofoil boats rely on water dynamic pressure or lift to support gravity, and most of the hull rises to reduce water resistance; but as the speed increases, the propulsion efficiency of its propellers decreases. Plummeting, to achieve high-speed sailing, it is necessary to configure a high-power engine, high energy consumption in exchange for high speed, the economy is extremely poor
[0003] Moreover, when the propeller speedboat suddenly accelerates or encounters swells at high speed, the hull is very easy to pitch up and even cause the ship to capsize

Embodiment 1

[0022] Such as diagram 2-1 , Figure 2-2 As shown, the paddle wheeled speedboat of the present invention includes a hull, and a ship power plant formed by a main engine driven propeller is arranged on the hull; the hull is a trimaran, and the two subhulls 6, 7 are arranged symmetrically on In front of both sides of the mother hull 8, the bottom surfaces of the two sub-hulls 6 and 7 are lower than the bottom surface of the mother hull 8; a rudder 5 is arranged at the rear of the mother hull 8; The lower edge of the paddle wheel 2 is lower than the bottom surface of the mother hull 8; the setting of the two sub-hulls 6, 7 not only increases the buoyancy, but also protects the two paddle wheels 2 at the rear, and also forms a suitable facing The angle of the water is more conducive to the stability when sailing in a static state and high-speed navigation. With the cooperation of the rudder 5, its buoyancy, sinking resistance and maneuverability are very excellent.

Embodiment 2

[0024] Such as Figure 3-1 , Figure 3-3 As shown, the paddle wheel speedboat of the present invention includes a hull 1, and a ship power plant formed by a main engine driven propeller is arranged on the hull 1; The paddle wheel 2 is composed of; the lower edge of the paddle wheel 2 is lower than the hull bottom 4; a rudder 5 is arranged at the hull 1 stern.

[0025] In order to facilitate sailing in a static state, the wheel shafts of the paddle wheels 2 on both sides are set to a height adjustable structure up and down, which can be realized by conventional lifting mechanisms such as screw type or hydraulic type; Figure 3-2 It shows that when the hull 1 is in a static state, the wheel shaft of the paddle wheel 2 is adjusted to the upper position, so that the lower edge of the paddle wheel 2 is higher than the hull bottom 4 but lower than the water surface. sailing.

Abstract

The invention discloses a paddle steamer. The paddle steamer comprises a boat body and a ship power device arranged on the boat body and composed of a host-driven propeller, wherein the propeller consists of two paddle wheels symmetrically arranged on the two sides of the boat body; and the lower edges of the paddle wheels are lower than the bottom surface of the boat body. The invention has the advantages that the modern host is combined with the traditional paddle wheels; the installation mode that the lower edges of the paddle wheels symmetrically arranged on the two sides of the boat body are lower than the bottom surface of the boat body is adopted, thus when the paddle wheels rotate at high speed, blades which are evenly distributed on the outer edges of the paddle wheels in the radial direction continuously and fast flap water surface backward and downward in turn; and as the density of water is high, enough forward and upward reacting force can be obtained, the upward component force supports the boat body to leap out of water, and the forward component force pushes the boat body to move forward. Therefore, only the tail of the boat body contacts a little part of water surface and slides on water surface and the balance of the boat body is maintained, thus avoiding extremely large water resistance, remarkably increasing the propelling efficiency and realizing the high-speed and economic navigation of ships.

Description

technical field [0001] The present invention relates to a paddle steamer, in particular to a paddle boat. Background technique [0002] Paddle steamers, which flourished in the era of steam engines, are low-speed and low-efficiency ship types, which have long been eliminated by propeller ships. This is the consensus of those skilled in the art; There are mainly propeller types; when sailing at high speed, planing boats and hydrofoil boats rely on water dynamic pressure or lift to support gravity, and most of the hull rises to reduce water resistance; but as the speed increases, the propulsion efficiency of its propellers decreases. In order to achieve high-speed sailing, a high-power engine must be configured to exchange high energy consumption for high speed, which is extremely economical. [0003] Moreover, when the propeller speedboat speeds up suddenly or encounters swells when sailing at high speed, the hull is very easy to pitch up and even cause the ship to capsize. ...
