Description

Technical Field

[0001] This patent relates to the field of ship propulsion technology, and in particular to a high-speed boat drive device based on a multi-section shaftless pump-jet structure. Background Art

[0002] The fields of shipbuilding, fluid dynamics, and mechanical design are crucial components of the development of modern shipbuilding technology. Shipbuilding primarily involves technical research in the design, construction, and maintenance of ships; fluid dynamics focuses on the motion and properties of fluids (such as water and air); and mechanical design focuses on technical issues related to the structure, performance, and design of mechanical equipment. With the advancement of science and technology, the speed and efficiency of ships have continued to increase. Two key technological breakthroughs have been the shaftless motor and the multi-section pump-jet structure. Among existing technologies, these two structures have been widely adopted. The shaftless motor, a new type of motor with an ironless design, offers advantages such as simple structure, light weight, high efficiency, and high power density, making it widely used in various mechanical equipment. The multi-section pump-jet structure achieves higher flow and pressure by combining multiple pump-jet units, and is widely used in areas such as ship propulsion systems.

[0003] However, existing technologies in this field still have some problems and shortcomings. First, while existing shaftless motors offer many advantages, their power density is still limited and cannot meet the requirements of some high-power marine propulsion systems. Second, while existing multi-section pump-jet structures can achieve higher flow rates and pressures, they are complex, heavy, and costly, and are susceptible to fluid dynamics, which can affect their performance and stability.

[0004] Based on the above shortcomings, it is necessary to make improvements. Summary of the Invention

[0005] The following presents a simplified summary in order to provide a basic understanding of some aspects of the disclosed embodiments.

[0006] This summary is not an extensive overview and is intended to neither identify key / critical elements nor delineate the scope of the embodiments.

[0007] Its sole purpose is to present some concepts in a simplified form as a prelude to the more detailed description that is presented later.

[0008] This patent adopts the following technical solution: it provides a high-speed boat drive device based on a multi-section shaftless pump-jet structure, including a boat and a power system; the boat includes a groove that runs through the bottom of the boat along the length direction of the boat, and the power system includes at least 3 shaftless power propellers, and the at least 3 shaftless power propellers are arranged at intervals in the groove.

[0009] Furthermore, in some optional embodiments: the power system includes a first shaftless power pump, a second shaftless power pump and a third shaftless power pump arranged in sequence from the bow to the stern of the boat, and the first shaftless power pump, the second shaftless power pump and the third shaftless power pump are in the same vertical plane.

[0010] Furthermore, in some optional embodiments: a line connecting the first shaftless power pump and the second shaftless power pump and a line connecting the second shaftless power pump and the third shaftless power pump intersect at an angle.

[0011] Furthermore, in some optional embodiments: the distance between the first shaftless power pump and the second shaftless power pump is greater than or equal to the distance between the second shaftless power pump and the third shaftless power pump.

[0012] Furthermore, in some optional embodiments: the rotational speed of the third shaftless power pump is greater than or equal to the rotational speed of the second shaftless power pump.

[0013] Furthermore, in some optional embodiments: the rotational speed of the second shaftless power pump is greater than or equal to the rotational speed of the first shaftless power pump.

[0014] The various specific technical features described in the specific embodiments of the present invention can be combined in any appropriate manner without contradiction.

[0015] In order to avoid unnecessary repetition, the present invention does not enumerate all the above combinations.

[0016] All other embodiments formed by combining any of the above structures fall within the protection scope of the present utility model.

[0017] The above-mentioned structure offers advantages over existing technologies in that it utilizes multiple shaftless motors rotating simultaneously to drive the blades within the tube at high speed, creating a multi-section shaftless pump-jet structure. This structure effectively increases power density, meeting the requirements of high-power marine propulsion systems. The simultaneous operation of multiple shaftless motors enables higher power output, thereby improving propulsion system efficiency and performance. The multi-section shaftless pump-jet structure is installed on the bottom of a high-speed boat. This installation method effectively reduces the effects of fluid dynamics and enhances performance and stability. The installation position and angle of the multi-section shaftless pump-jet structure can be precisely calculated and optimized to ensure optimal fluid performance. The combination of shaftless motors and the multi-section pump-jet structure simplifies the structure, reduces weight, and lowers costs. The shaftless motors offer a simple structure, light weight, low cost, and ease of maintenance and replacement. The simplification of the multi-section pump-jet structure further reduces cost and weight, improving system reliability and stability. Optimizing the internal structure of the multi-section shaftless pump-jet structure can further enhance its performance and stability. For example, optimizing the design and layout of the blades can reduce the effects of fluid dynamics and improve propulsion efficiency. At the same time, motor efficiency and response speed can be improved by optimizing motor design and control algorithms. The performance and stability of multi-section shaftless pump-jet structures can be further enhanced by adopting advanced materials and manufacturing processes. For example, high-strength, lightweight materials such as carbon fiber and titanium alloys can be used to improve the strength and durability of the structure. Furthermore, advanced manufacturing processes such as 3D printing and laser welding can be employed to enhance the precision and consistency of the structure. BRIEF DESCRIPTION OF THE DRAWINGS
