Description

Technical Field

[0001] This patent relates to the field of ship propulsion technology, and in particular to a high-efficiency and energy-saving jet pump structure that can recover kinetic energy. Background Art

[0002] As the performance requirements of ship propulsion systems become increasingly higher, traditional power jet pumps have many components, occupy a large space in the cabin, have high energy losses, and are difficult to control shaft vibration and noise. This is especially true for compact ships such as boats and submarines, which have limited cabin space and require high maneuverability and a stable and reliable shaft system. Water jet pumps have a series of advantages, such as a small turning radius, low noise and vibration in the ship cabin, and a simple structure. Therefore, water jet pumps have been widely used in compact ships such as submarines and yachts. Electric water jet pumps are increasingly used in the field of ships. However, for electric water jet pumps, although the motor drive has a high transmission efficiency, it still poses a huge challenge in terms of endurance. Existing technical solutions mostly increase the battery capacity to improve the endurance of the boat, but this solution is still limited by battery technology and has bottlenecks. Based on the above shortcomings, it is necessary to improve them. Summary of the Invention
