[0002] With the development of shipping and marine engineering, more and more ships are being used in daily life and production. With the diversification of production and life, the number of ship types is also increasing. For some ships with shallow draft, traditional auxiliary propulsion systems such as lateral thrusters have a small draft area and draft pressure in the water intake section. The propeller is not immersed deep enough or even exposed to the water surface, resulting in suction, which makes it unable to work effectively, causing the ship to slow down or even stop moving.

[0003] How to increase the draft area of ​​the water absorption section and increase the water absorption pressure in the water absorption section has become an urgent problem to be solved.

[0004] The present invention seeks to alleviate or at least mitigate such problems or deficiencies by providing a new or otherwise improved propulsion system. Summary of the Invention

[0056] In a more specific embodiment, the draft area n between the water outlet and the water intake is 0.3.

[0057] In a more specific embodiment of the adjusting member 2 of the present invention, the structural structure of the adjusting member 2 is further explained below. The adjusting member 2 includes an adjusting seat 21, which is detachably mounted on the bottom plate 1 and surrounds the water suction port of the water inlet section 11; a first slide plate 22, which can be inserted from one side of the adjusting seat 21 and can slide along the side of the adjusting seat 21; a first blocking plate 23, which is detachably connected to the first slide plate 22 and is used to prevent the first slide plate 22 from falling off from the adjusting seat 21; a second blocking plate 24, which is detachably connected to the first slide plate 22 and is used to prevent the first slide plate 22 from falling off from the adjusting seat 21; a second slide plate 25, which can be inserted from the other side of the adjusting seat 21 and can slide along the other side of the adjusting seat 21; a third blocking plate 26 detachably connected to the second slide 25 to prevent the second slide 25 from falling off the adjustment seat 21; a fourth blocking plate 27 detachably connected to the second slide 25 to prevent the second slide 25 from falling off the adjustment seat 21; a first ear plate 28 detachably connected to the adjustment seat 21, on which a first hydraulic cylinder 281 is detachably mounted, a first connecting plate 282 being connected to the output end of the first hydraulic cylinder 281, and the first connecting plate 282 being detachably connected to the second blocking plate 24; and a second ear plate 29 detachably connected to the adjustment seat 21, on which a second hydraulic cylinder 291 is detachably mounted, a second connecting plate 292 being connected to the output end of the second hydraulic cylinder 291, and the second connecting plate 292 being detachably connected to the fourth blocking plate 27;

[0067] In some embodiments, in order to further prevent debris from entering the water inlet section 11 and affecting the normal water inlet of the water inlet section 11, a filter net can be detachably installed in the water suction port of the water inlet section 11, and the size of the filter net is adapted to the size of the water suction port of the water inlet section 11.

[0068] Another technical problem to be solved by the present invention is a method for using a propulsion system for a ship.

[0069] S1. Turn on the first motor 14, which drives the pump shaft 15 to rotate, and at the same time drives the built-in impeller 1a on the pump shaft 15 to rotate, so as to drive the liquid to be injected into the water suction port of the water inlet section 11 and to flow out from the water outlet end of the water outlet section 12;

[0071] S3, turning on the second motor 31, which drives the rotating shaft 32 and the first booster impeller 33 to rotate, thereby increasing the flow rate in the water inlet section 11;

[0072] S4, the first swing arm 17 and the second swing arm 18 turn leftward or rightward at a predetermined angle of 0°-180° along one side of the water outlet end of the water outlet section 12.

[0073] In summary, the regulating component 2 and the boosting component 3 are provided to close or open the water suction port of the water inlet section 11, and the area of ​​the water suction port of the water inlet section 11 can be intermittently increased or decreased so that there is a pressure difference between the water suction port and the water outlet; at the same time, it is used to increase the flow rate in the water inlet section 11, thereby increasing the draft area of ​​the water suction section and increasing the draft pressure, so that the propulsion system is more stable during operation, and has high ease of use and versatility.
