FR2974562A1 - Propulsion system for e.g. pleasure boat, has aspiration pump driven by electrical motor and including variable high pressure outlet adapted for pushing boat, where pump draws water to outlet according to size of boat - Google Patents

Abstract

The system has an aspiration pump driven by an electrical motor and including a variable high pressure outlet adapted for pushing a boat. The pump draws water using the motor to the outlet according to size of the boat for pushing the boat along forward or backward direction. A solenoid proportional valve manages flow of the boat along forward or backward direction. The system includes four elements for providing energy sources e.g. water, solar power, wind power, and electrical power, required by the boat. The first element includes tubes with fins to generate electricity.

Description

Pressure propulsion system Project of pressure propulsion either electric or low-energy thermal engine on pleasure craft or trade.

This system operates without propeller, shaft line and clutch as shown in figure 1 and 2 (see drawing).

Explanations of abbreviations:

POM AS: Water Suction Pump ME: HP Electric Motor: High Pressure EL: Proportional Solenoid Valve V: TH Opening and Closing Valve: Thermal Motor

- Figure 1 :

A pump (POM AS) draws water by electric motor (ME) or heat engine (TH) at its output at high pressure (HP) variable depending on the size of the boat (15 bar at 1500 bar pressure, push to front and back, eg: figure 2). Pushing it forward and backward is not handling a proportional solenoid valve (EL) in order to direct the flow. As can be seen in Figure 1 there is more propeller neither clutch nor shaft line.

This system is an evolution because a very low energy consumption and a low CO2 emission not see at all because some boats can be powered by solar panel and small wind. The installation of this system is very advantageous compared to the current engine whose cost varies between 30,000 and 500,000 euros without counting energy consumption and weight, all for the same power. The rear side thrust system is used to steer the boat (fig 1). Two rudders are needed for driving the boat. - Figure 2:

Figure 2 shows a bow engine at the front as well as a push back to stop the boat (EL) and two side outputs controlled by (ME and HP) otherwise the system is almost the same as figure 1.

My project has little impact on the environment because there is low energy consumption and very little noise.

It consists of four elements: water, wind, sun and electricity.

- element: water.

Two hoses with fins (figure 2) at the front of the boat, the latter moving forward will produce electricity (example of the bike dynamo).

- let 'element: the wind.

Small wind turbine, the boat moving moves air that will turn them that will produce electricity or wind that blows naturally.

- 3rd element: the sun.

The solar panels will also produce electricity.

- 4th element: electricity.

Plugging into electrical outlet in marinas or other.

The first three elements combined together have the advantage of emitting no CO2 and allow the boat to self-manage because it requires a small electric motor.

A boat between ten and fifteen meters with a motor of fifty horses consumes about ten liters of fuel per hour. With our system, we get the same power without polluting.

We can adapt this system on much larger boats with consumption between ten and three hundred liters per hour for the same power we reduce it by more than half with a generator that will power a much larger electric motor . 3) The advantages of this system:

10_ Energy saving 2 ° _ Very low CO2 emissions 3 ° Low purchase cost compared to the current engine 4 ° _ Low repair costs 5 ° _ Low noise 6 ° _ No vibration 7 ° _ Low weight

2) The (minor) disadvantages of this system:

10_ Bring a high-pressure hose (HP) to the front of the boat for reverse gear 2 ° _ Cleaning filter (sediment, silt ...) that already exists on most current boats

This is insignificant compared to the economy that can generate this system.

- It is mandatory to equip the boat with two rudders: despite this it will be more difficult to maneuver than the rear lateral thrust. -This system can adapt to submarines due to lack of propeller: indeed without propeller submarine is less detectable. - By also putting this propulsion system in front of the submarine it can turn on itself at 3600 {very quickly) What is not currently the case in the little I know submarines
