Abstract

The present invention provides a propulsion system of a boat, which mainly includes a flow guide cover, a propulsor, a nozzle, a left-and-right turn ring, an up-and-down turn ring, and a reverse direction guide cover, in which the flow guide cover is provided with a water flow channel for guiding water passage. The propulsor includes a main body and a propeller. The nozzle is installed on the outlet end of the main body and extends backwards. The left-and-right turn ring and the up-and-down turn ring are separately sleeved on the front and rear sections of the nozzle. The reverse direction guide cover is installed behind the nozzle. Thus, when the propeller rotates, water initially flows in through the water flow channel of the flow guide cover, and subsequently is pressurized by the propeller inside the main body and ejected rapidly through the nozzle. The left and right oscillation of the left-and-right turn ring controls the left and right turning of the boat. The up and down oscillation of the up-and-down turn ring controls the depression angle and elevation angle of the boat. Through the reverse direction guide cover, the boat is able to move backwards. The above-mentioned design greatly improves the operability and safety of the boat.

Description of the Invention: [Technical Field of the Invention] The present invention relates to a propulsion system for a boat, and more particularly to a propulsion system that can improve the handling and safety of a boat. [Prior Art] Please refer to the conventional propulsion system (10) for a large ship (1) shown in the first figure, which mainly includes a propeller (12) and a rudder plate (14). The water flow generated by the rotation of the propeller (12) and the left and right yaw of the rudder plate (14) can drive the boat (1) forward and control the boat (1) to turn, but because the rudder plate (14) is located Behind the propeller (12), the rudder plate (14) with a predetermined volume will inevitably offset the thrust of the part of the propeller. In addition, the vortex current loss caused by the rotation of the open propeller (12) will cause such boat propulsion. Part of the loss of efficiency, in addition, because the navigation board (14) is a plate-like shape, a considerable yaw angle is required when steering the boat to make the boat effectively turn left or right, so the boat (1) ) The handling is poor. Next, please refer to the conventional propulsion system (20) for the speedboat (2) shown in the second figure, which also includes a propeller (22) and a rudder plate (24) located behind the propeller (22). In addition to the above-mentioned lack of the above-mentioned speedboat propulsion system, in order to improve the handling of the speedboat (2) when docking, a side thruster (26) is usually provided at the hull section of the speedboat (7), but the lateral direction is installed. In addition to increasing the manufacturing cost, the speedboat of the propeller (26) will also reduce the utilization of the internal space of the hull, which is difficult to achieve. In addition, since the propellers (12, [S] 3 201116453 22) and the rudder plates (Η, 24) of the above two propulsion systems (1〇, 2〇) are located at the bottom of the boat, it is easy to rotate. Stirring in plastic bags, fishing nets or water plants can cause damage to the propeller (12 '22), or damage to sea creatures (such as the mermaid manatee) or divers or swimmers, causing unnecessary harm. At the same time, the above boats are only suitable for use in deep waterways. Most importantly, both of the above propulsion systems (10, 20) have no control and flexible design of the boat receding mechanism, and all of these are still in need of improvement. SUMMARY OF THE INVENTION A primary object of the present invention is to provide a marine propulsion system that can greatly enhance the handling and safety of a boat. In order to achieve the above object, the propulsion system of the present invention includes at least a shroud, a propeller, a -nozzle, and a left and right steering ring. The shroud has a water guiding passage for guiding the water to flow through; the propeller has a body and a screw, and the position of the fourth (four) portion is provided with a _ hour wing for pre-sending the flow of water from the channel to rotate in a specific direction. _The rotation is set to be behind the fixed wing, and the rotation direction of the screw (4) is opposite to the flow of water through the fixed flap; the nozzle is made of a flexible material, and is disposed on the body of the actuator The σ end extends backwards; the left and right steering rings are sleeved on the nozzle to hide, such as the view and the New 姊 (4) ^ can drive the nozzle to produce a leftward or rightward yaw motion relative to the propeller. By the left and right yaw of the left and right steering rings, the left and right yaws of the nozzle can be synchronously driven, so that the high-speed water jetted from the screw (4) can pass through the 201116453 to flexibly increase the left side of the nozzle of the boat. The right yaw towel drives the boat to turn and control. In the present invention, the propulsion system of the present invention can further lower the steering ring above the four nozzles, and the upper and lower steering rings are pivotally connected to the left and right steering rings on two sides to drive the nozzle to generate the opposite = yaw up or down to lower the pitch and elevation of the boat

The boat has to maintain a minimum resistance posture. Please refer to Figures 11 to 14 and please match the third to fifth figures. The reverse guide (80) utilizes a pair of brackets (82) and a housing (41) of the body (41) of the pusher (4). The pivoting is such that the reverse guide (80) can be driven by a third driving device (86) to be relatively advanced between a first position (P1) (ie, rear) and a second position (p2) (ie, upper). The device (40) pivots and yaws. When the reverse guide (8〇) is in the first position (Pl) (ie, rear) as shown in the thirteenth figure, the reverse guide (8〇) is located in the direction in which the nozzle (50) extends, at this time by the propeller The high-speed water flow from the rotation will be changed to the front by the reverse back cover (80) to allow the boat to retreat. When the reverse guide cover (80) is at the second position (P2) (ie, above), as shown in FIG. 11, the reverse guide cover (80) is located above the pusher (40) away from the direction in which the nozzle (50) extends. At this time, the water flow is directly sprayed to the rear, so that the boat can go forward. In addition, it must be further explained that the opposite guides (80) have two water conduits (84) on both sides, and the water conduits (84) are mainly oriented forward and have a small angle downward, as shown in the fourth figure.
