Power type ship propelling system

Abstract

The invention relates to a propulsion system of a power-style ship, comprising a casing, a propeller, an oil-pressure driving device and an air guide sleeve. The casing is connected with a stern part of the power-styled ship and is provided with a chamber and a guiding channel. The propeller is arranged on the stern part and is positioned in the guiding channel. The oil-pressure driving device is arranged in the chamber of the casing and is provided with a driving part and a linkage part pivoted with the driving part. The air guide sleeve covers the propeller with the common axis and is pivoted with the linkage part to lead the linkage part to be driven by the driving part so as to drive the air guide sleeve adopting the center of the propeller as an axes to partially sway to the left and right, not only controlling the left or right turning of the power-style ship but also controlling the left or right backing of the ship when the propeller reverses and leading the engine of the power-style ship to be arranged at a position near the stern part so as to enlarge the internal space.

Description

technical field [0001] The present invention relates to a power boat, in particular to a propulsion system for a power boat, which can effectively expand the space inside the power boat. Background technique [0002] Please first refer to the known small boat 1 shown in Fig. 1, the engine 11 inside the boat 1 is connected to a drive shaft 12, and the drive shaft 12 passes through the bottom 13 of the boat 1 obliquely downwards, and passes through an A frame 14 sets Suppose and connect a propeller 15. The boat 1 is provided with a rudder 17 at the stern 16 . [0003] Because the components of the above-mentioned boat 1, such as the A-frame 14, the rudder 17 and the propeller 15, are all located below the bottom 13, it is easy to cause the boat 1 to suffer too much resistance when propelled, and these exposed components are also exposed. It is easy to touch the reef or planktonic plank and cause damage. In addition, the engine 11 of the boat 1 is usually located in the cent...

Problems solved by technology

[0003] Because the components of the above-mentioned boat 1, such as the A-frame 14, the rudder 17 and the propeller 15, are all located below the bottom 13, it is easy to cause the boat 1 to suffer too much resistance when propelled, and these exposed components are also exposed. Easy to touch the reef or planktonic plank and cause damage

In addition, the engine 11 of the boat 1 is usually located in the center of the boat 1, which limits the use of space inside the boat 1.

[0004] As shown in Figure 2, the known large boat 2, although the usable space inside the boat 2 is much smaller than that of the small boat 1, the engine 21 of the boat 2 is still in the center of the boat 2, which still affects the 2 The utilization rate of the internal space. Moreover, the propeller and the rudder are still located under the boat. In addition to being easy to collide with hidden reefs, it is easy to cause damage to people in the sea or marine conservation organisms such as manatees, and may even be caught by the propeller 22 because of seaweed The root of the propeller 22 was broken, causing damage to the plants in the sea

In addition, when the boat 2 is retreating, it is necessary to control the steering of the boat 2 through a thruster 24 (Bow thrusters) located at the bow 23 and a thruster 26 (Stern thrusters) located at the stern 25, but the two propulsion The components of the device 24, 26 also take up a lot of space inside the boat 2
