Embodiment Construction

[0025] see figure 1 , the 360° full-rotation board inboard and outboard (two-engine) contra-rotating paddle propulsion device of the present invention comprises: the paddle rudder revolving body 18 fixed on the stern of the ship; The Huff-type square box composed of the upper and lower shells 11 and 10 of the heat sink is screwed with the lower conical bracket 3 with the circular plate base 10 as the bracket; Transmission chain, drives the second transmission chain of the rotary part in the paddle rudder rotary body 18, 360 ° of full rotation (two machines) synchronously runs the electronic control drive mechanism 17 and the highly elastic coupling 15 connected with the prime mover.

[0026] see figure 1 with 34. When the prime mover is a diesel engine, the upper casing includes a rotating shaft 34 rotatably arranged between the upper and lower casings 10 and 11, whose axis is perpendicular to the intermediate drive shaft 19 and one end extends out of the upper casing; A sm...

Abstract

The invention discloses a 360-degree full revolving inboard and outboard (dual-machine) contrarotating propeller propulsion device, of which the core is a contrarotating propeller technology in the case of high speed of a screw propeller of a high-speed ship or craft, and the energy conservation, ship speed and propulsion efficiency are improved by about 10 percent. In the device, an encoder, a servo motor, a reducer and large and small cylindrical gears are connected with a lower box body through a rotary sleeve to realize 360-degree full revolving. The ship is flexible in turning around, 1.6-1.8 times faster in backing and safe in shipping. A hydraulic or electromagnetic clutch and an electronic gear shifting hydraulic control valve are adopted; and two variable frequency motor oil pump units are used for supplying oil to realize safety and energy conservation. Radiating fins are additionally arranged; and a half square box body is connected with a conical bracket and the ship body to absorb propulsion force, vibration and collision force and protect the bracket. The lower box body is streamline-shaped on the front section and the rear section and wing-shaped on the middle section, so that the resistance is reduced. The device has a novel and compact structure, small external size and light weight. The core technology of the invention is that: the encoder and the variable frequency motor are communicated with a cab touch instrument view screen through a driver and a PLC (Programmable Logic Controller) single cable; and a host accelerator and a clutch are electronically controlled to realize double-machine 360-degree synchronous complete control.

Description

technical field [0001] The present invention relates to power propulsion devices for motor boats and boats, in particular to a 360° full-rotation (two-machine) synchronous operation with the best propulsion and control effects and the use of world-advanced inboard and outboard (two-machine) that can save a lot of power (save fuel consumption) Ship propulsion device with high-speed counter-rotating propeller technology. [0002] 1. The fuel-saving principle of the contra-rotating propeller is that the energy lost by the front propeller's trumpet-shaped splash rotation is absorbed by the rear propeller and turned into a horizontal straight line to generate greater energy, making the thrust much higher than that of a single propeller. The present invention is based on the comparison test and navigation practice of low-speed propellers of many different types of ships for 10 years, adopts the high-speed propeller map and designs high-speed counter-rotating propellers through theor...
