Complete machine structure type of 360-degree full-rotation board internal and external double-machine-contra-rotating propulsion device

Abstract

The invention discloses a complete machine structure type of a 360-degree full-rotation board internal and external double-machine-contra-rotating propulsion device. The complete machine structure type is provided with a diesel engine and a motor (transverse and vertical arrangement) as hosts, and uses a high-speed contra-rotating paddle and a water lubrication technology; the energy saving is about 15%, the total efficiency is 10% higher than that of the low speed, the speed propulsion efficiency is 10%-12% higher than that of the single paddle, a high-molecular bearing for water lubricationand a stainless steel special bearing which is never worn and a special sealing member are environment-friendly and zero-pollution; an oil motor or a servo motor speed reducer, large and small cylindrical gears and large and small spiral bevel gears are used for realizing 360-degree full revolution, a handle is matched with the large and small cylindrical gears, the spiral bevel gears achieve + / -30-degree rotation; the reversing speed is faster 1.6-1.8 times, and the navigation is safe; the external cooling fin Hough-type square box is connected with the conical support and the hull, or the cylindrical box body is connected with the rectangular frame and the hull, the lower box is streamlined, the middle-section wing rudder pressurizes the water plate, energy is saved, and the impact forceis absorbed; the driver, the PLC single-cable connect cab touch instrument view screen, and the double-machine synchronous and non-synchronous 25-form electronic full-process control; intelligent control panel with ternary lithium battery or lithium iron phosphate battery module.

Description

technical field [0001] The present invention relates to the structural type of the complete machine of power propulsion devices for motor boats and boats, in particular to the world-advanced inboard and outboard dual-engine synchronous and non-synchronous dual-machine synchronous and non-synchronous, which adopts a large amount of energy saving. The structural type of the whole ship propulsion device with high-speed counter-rotating propeller water lubrication technology. [0002] 1. The counter-rotating propeller is composed of two parallel-connected propellers connected in series on the same side with the same axis and the same horsepower (or different horsepower). The number of blades of the two propellers is different, and the direction of rotation is opposite. [0003] In the single-propeller propulsion system, the energy lost in the eddy in the wake cannot be used, while in the counter-rotating propulsion system, the energy lost by the front propeller is absorbed by the ...

AI Technical Summary

Problems solved by technology

The 360° full-turn drive mechanism only talked about one scheme, and did not involve different structures and innovative features under various powers

More importantly, it did not mention the vertical arrangement of the motor, nor did it propose the lighter weight, the simplest upper box and rack solution, the more convenient and quick disassembly and assembly of innovative components, nor did it mention the innovative motor, controller, control board, Batteries, power panels...etc.
