Marine turbine rim power dragged podded propeller

Abstract

The invention discloses a marine turbine rim power dragged podded propeller, comprising a pod body; a motor and a rib power generator are disposed in the pod body, the motor is connected with a transmission shaft, the transmission shaft is connected with a screw, one end of the screw is connected with a turbine, the turbine is connected with the rim power generator in the pod body, a pod support is fixedly connected to the pod body, and the pod body is mounted on an outer hull through the pod support. At the premise of providing thrust required by ship operation, rotational energy of weak flowof the screw in the dragged podded propeller is converted into electric energy, so that the rotational energy of weak flow of the screw is achieved; the walk flow created by rotation of the screw drives the turbine to rotate so as to drive the rim power generator to generate power, and electric energy required by the motor can be effectively supplemented.

Description

technical field [0001] The invention relates to the field of ship control, in particular to a ship-used turbine rim power generation towed pod propeller. Background technique [0002] At present, various ships sail in various seas of the world, causing a large amount of fuel consumption and bringing high operating costs. As the EEDI (energy efficiency design index) proposed by IMO came into effect on January 1, 2013, the world shipbuilding industry, especially developing countries, has been significantly affected. The design and development of green ships with low energy consumption and high efficiency will become the development trend of the ship industry in the future, and energy conservation and emission reduction will become the primary factor considered in ship design. At present, the propulsion method used in the ship field is mainly the traditional diesel engine shaft propeller, but the low efficiency, high emission, and poor vibration and noise performance of the tr...

[0003] Although pod propulsion reduces energy consumption to a large extent, the spinning wake drawn backward by the propeller still causes a large amount of energy loss

In order to recover the rotational energy of the propeller wake, a ship propeller residual energy power generation system with the application number of 201210002310.8 in the prior art realizes the purpose of energy recovery by installing a power generation impeller behind the propeller to recover the wake energy of the propeller, but the generator Placing the impeller fixing bracket and transmission mechanism in the water flow behind the ship will increase additional resistance, thus causing the ship to require a lot of energy during navigation
