Description

Technical Field

[0001] The utility model relates to the technical field of propellers, in particular to a marine engine power propulsion device. Background Technique

[0002] A propeller is a propulsion device that generates thrust by rotating blades. The propeller pushes water backward through the rotation of the blades, thereby generating forward thrust. When the blades rotate, they form a rotating flow field in the water, which exerts a force on the surrounding medium and pushes the object forward. The propeller has the advantages of simple structure, high reliability, and high efficiency.

[0003] In the Chinese invention patent application publication specification CN 219668465U for a marine engine power propulsion device, it is disclosed that "a bearing base, a bearing sliding frame, an installation side block, and a bearing support plate; a driving motor is fixedly installed at one end of the top of the bearing base, a bearing bracket is fixedly installed at the other end of the top of the bearing base, and assembly sliding frames are fixedly installed on both sides of the bearing bracket; an assembly sliding groove is formed through the side of the bearing sliding frame, and the bearing sliding frame is slidably sleeved outside the bearing bracket through the assembly sliding groove. Assembly sliding plates are fixedly installed at both ends of the side of the bearing sliding frame, and a propulsion motor is fixedly installed on the side of the assembly sliding plate." The technical solution disclosed in this patent works through a motor drive device. Since the load capacity of the ship is limited, the weight of the equipped battery should not be too large. When the battery power is exhausted, the device cannot be propelled. Therefore, a propulsion device that can connect to other power sources is needed. Content of the Utility Model

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Refer to Figures 1-5, A marine engine power propulsion device, including an electric motor 1. A hoisting plate 2 is fixedly installed on the outer surface of the electric motor 1. A gearbox 3 is fixedly installed at the front end of the hoisting plate 2 located on the electric motor 1. A connecting rod 4 is fixedly installed above the hoisting plate 2. The top end of the connecting rod 4 is fixedly installed with a support platform 5. A sleeve 6 is fixedly installed above the support platform 5 and at the rear end of the gearbox 3. A rotating shaft 7 is rotatably connected inside the sleeve 6. Blades 8 are fixedly installed on the outer surface of the rotating shaft 7 located inside the sleeve 6. One end of the rotating shaft 7 above the support platform 5 located outside the sleeve 6 is fixedly installed with a connecting block 9. The rotating shaft 7 at the rear end of the gearbox 3 extends into the interior of the gearbox 3. A driving gear 10 is fixedly installed on the outer surface of the rotating shaft 7 located inside the gearbox 3. The two sleeves 6 are connected and penetrated by two conduits 14. A blade shaft 11 is rotatably connected inside the gearbox 3. A propeller 12 is fixedly installed at one end of the blade shaft 11 located outside the gearbox 3. The blade shaft 11 is connected to the output shaft of the electric motor 1. A driven gear 13 meshing with the driving gear 10 is fixedly installed on the outer surface of the blade shaft 11.

[0024] A sliding clamping shaft 15 is arranged inside the gearbox 3. The sliding clamping shaft 15 is slidably clamped with the blade shaft 11. The driven gear 13 is fixedly sleeved on the outer surface of the sliding clamping shaft 15. The sliding clamping shaft 15 is clamped with the output shaft of the electric motor 1 through a clutch 22. A rotating plate 16 is fixedly sleeved on the outer surface of the sliding clamping shaft 15. A sliding frame 18 is sleeved on the outer surface of the rotating plate 16. A lead screw shaft 19 is meshed at the bottom end of the sliding frame 18. The lead screw shaft 19 extends outside the gearbox 3. Through such a setting, a power source switching device can be arranged in the middle, so that the useless work of the electric motor 1 driving the liquid circulation can be reduced, and at the same time, the resistance of the electric motor 1 when driving the propeller to rotate through the liquid circulation can be reduced.

[0025] A support sleeve 20 is fixedly installed inside the gearbox 3. The sliding clamping shaft 15 is rotatably connected inside the support sleeve 20. The lead screw shaft 19 is rotatably connected with the support sleeve 20. By setting the support sleeve 20, the sliding clamping shaft 15 can be supported.

[0026] A ball 21 is rotatably connected to the inner wall of the sliding frame 18. The ball 21 is rotatably connected with the rotating plate 16. Through such a setting, the friction between the sliding frame 18 and the rotating plate 16 can be reduced.

[0027] The included angle between the two conduits 14 is greater than the included angle between adjacent blades 8. Through such a setting, it can be ensured that the blades can squeeze the liquid into the interior of the conduits 14. The material of the conduits 14 is a metal braided hose. Through such a setting, breakage can be avoided.

[0028] The distance between the support sleeve 20 and the sliding frame 18 is greater than the separation distance of the clutch 22. By setting the distance between the support sleeve 20 and the sliding frame 18 and the distance between the rear end face of the driving gear 10 and the rear end face of the driven gear 13 like this, any connection between the clutch 22 and the gears can be ensured.

[0029] A knob 17 is fixedly installed on the outer surface of the lead screw shaft 19 located inside the transmission 3. The knob 17 is rotatably connected to the transmission 3. By setting it like this, it is convenient to rotate the lead screw shaft 19.

[0030] During use, the motor 1 is powered by a power source to drive the propeller 12 to rotate. When the power source cannot be used, the device is lifted, and the lead screw shaft 19 is rotated to horizontally move the rotating plate 16 to separate the clutch 22 and engage the gears. At this time, it can be connected to the rotating shaft of other power sources such as a diesel engine, or manually rotate the handle and connect it to the connecting block 9. By driving the rotating shaft 7 to rotate, the liquid is squeezed into the corresponding cavity to drive the blades 8 inside to rotate, and then the propeller 12 can be driven to rotate through gear transmission, avoiding the problem of being unable to move in case of emergency.

[0031] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
