Technical Field
The present invention relates to a propulsion system for a power boat, and more particularly, to a propulsion system which can increase the propulsion efficiency and is also applicable to a boat having a shallow draft.
Background
The outboard engine is a detachable power device installed at the stern, mainly transmits the power provided by a power source (such as an internal combustion engine or a motor) to a propeller, and pushes the boat to advance by the rotation of the propeller.
In order to make the outboard motor have good propulsion efficiency, the propeller is wholly sunk into water in the traditional design so as to ensure that the propeller has enough draught, but in such a way, besides the increase of water resistance, the propeller is easy to collide with a river bed or stir into foreign matters (such as plastic bags, fishing nets or aquatic plants) at the same time, so that the propeller is damaged, and aquatic organisms can be even hurt.
Disclosure of Invention
The present invention has been made in view of the above problems, and it is an object of the present invention to provide a propulsion system for a power boat, which can improve the propulsion efficiency and can be applied even when the draft of the boat is shallow.
To achieve the above objective, the propulsion system of the present invention comprises a support frame, an outboard engine, a diversion assembly, and a water diversion seat. The support frame is arranged at the stern of the power boat; the outboard engine is arranged on the support frame and is provided with an impeller, and the axis position of the impeller is higher than the bottom of the power boat; the guide assembly is provided with a guide ring and a nozzle, the guide ring is covered on the impeller, and the nozzle is connected to the rear end of the guide ring and is adjacently arranged on the impeller; the water diversion seat is arranged at the stern of the power boat and is positioned below the support frame, the bottom of the water diversion seat is provided with a water diversion port, the water diversion seat is provided with a water drainage port facing the water diversion ring, and a water diversion channel is formed between the water diversion port and the water drainage port.
Through the design, when the impeller starts to rotate, water flow at the bottom of the ship is sucked into the water guide channel through the water guide port of the water guide seat, then is discharged into the flow guide ring through the water discharge port of the water guide seat, and finally is sprayed out from the nozzle after the flow rectification action of the impeller, so that the water flow is in a low-pressure and large-flow spraying state, the propulsion efficiency can be improved compared with the prior art, and the power type boat is also suitable for use when the draft of the power type boat is shallow.
The detailed construction, features, assembly or use of the propulsion system for a powered boat provided by the present invention will be described in the detailed description of the embodiments that follow. However, it will be understood by those skilled in the art that the detailed description and specific examples, while indicating the preferred embodiment of the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
