Abstract

The invention relates to a waterpower propulsion system with a water absorption passageway and belongs to the technical field of waterpower aircrafts. The system comprises a water inlet, the water absorption passageway, propellers, propulsion motors and a water outlet; and the propellers are located in the propulsion motors and arranged in a multi-stage mode. According to the waterpower propulsion system with the water absorption passageway, the multi-stage-arranged propellers are adopted and arranged in the propulsion motors and are each of a non-shaft structure; through multi-stage arrangement, under the requirement that the total propulsive power is ensured, the outer diameter and size of the single propulsion motor can be reduced, and the over large space, where the motors are placed, of the water absorption passageway is avoided. Meanwhile, by adoption of multi-stage arrangement, the capacity of redundancy degree improvement is achieved, and under the condition that one propulsion motor or two propulsion motors break down, the effect that at least one propulsion motor continues to work can further be ensured.

Description

technical field [0001] The invention relates to a hydraulic propulsion system, more specifically, the invention relates to a hydraulic propulsion system with a water absorption channel, which belongs to the technical field of hydraulic vehicles. Background technique [0002] At present, human development is facing resource shortage and environmental pollution, and ocean resources are extremely rich. How to develop the ocean in a sustainable and environmentally friendly way is a problem that determines the destiny of human development. Green propulsion is an important direction for the development of ships in the future. Ship emission standards are becoming more and more stringent. Improving the operating efficiency of hydraulic vehicles is one of the main ways to achieve green propulsion. [0003] Ship navigation is mainly affected by wave-making resistance, water-dividing resistance and hull friction resistance. Among them, wave-making resistance generally accounts for more...
