Description

Technical Field

[0001] This utility model relates to the field of marine technology, specifically to a high-efficiency marine propulsion device. Background Technology

[0002] Marine propulsion systems are the core devices that convert ship power into thrust, and their technological development directly affects a ship's navigation efficiency, maneuverability, and environmental performance.

[0003] Propeller propellers are one of the most commonly used propulsion devices. They primarily use an electric motor to drive a propeller to rotate, which in turn pushes water to generate a reaction force that propels the ship. However, their use has the following drawbacks:

[0004] The propeller blades are a whole unit, but the stress points at the connection between the blade tip and the shaft are too concentrated. When the propeller blades are running under high resistance, they are prone to shaking, which reduces the propulsion effect. Utility Model Content

[0005] I. Technical problems to be solved

[0006] The technical problem this invention aims to solve is that the blades tend to vibrate during rotation, which affects the propulsion effect.

[0007] II. Technical Solution

[0009] The propeller includes a cylinder and blades evenly arranged on the outer side wall of the cylinder along the circumference of the cylinder. A shock-absorbing sleeve is tightly fitted between the blades and the cylinder. The shock-absorbing sleeve is made of rubber.

[0010] The inner wall of the cylinder is provided with multiple slots that penetrate both ends of the cylinder along the circumferential direction. A connecting rod is inserted into the cylinder. The side wall of the connecting rod is provided with a limiting plate that fits into the slot. The front end of the connecting rod is connected to a hemisphere, and the rear end is connected to a drive motor. The diameter of the hemisphere is equal to the diameter of the outer wall of the cylinder.

[0011] As an improvement, the anti-shake sleeve is bonded to the cylinder and the blade, and the thickness of the end of the anti-shake sleeve connected to the cylinder is greater than the thickness of the other end, with a smooth connection between the two ends.

[0012] As an improvement, the connecting rod is provided with an annular groove on the side wall outside the cylinder, and a rubber ring with an outer wall diameter larger than the inner wall diameter of the cylinder is fitted inside the annular groove.

[0013] As an improvement, the diameter of the outer wall of the rubber ring is smaller than that of the cylinder, and a ring fitted around the rubber ring is connected to the end of the cylinder that is in contact with the rubber ring.

[0014] As an improvement, the propeller is fitted with a cylinder, and multiple support rods connect the cylinder to the drive motor.

[0015] As an improvement, multiple annular baffles are provided between the inner walls of the front end of the cylinder.

[0016] III. Beneficial Effects

[0017] The advantages of this utility model compared with the prior art are as follows:

[0018] This invention effectively absorbs the vibrations generated during blade operation through a three-dimensional streamlined structure composed of a cylinder, blades, and anti-vibration sleeve, making the blades more stable during rotation and improving propulsion. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example 1

[0026] As attached Figure 1-4As shown, a high-efficiency marine propulsion device includes a propeller and a drive motor 1. The propeller includes a cylinder 2 and blades 3 evenly arranged on the outer side wall of the cylinder 2 along the circumference of the cylinder 2. There are five blades 3, which are evenly distributed on the surface of the cylinder 2 and integrally formed with the cylinder 2. A shock-absorbing sleeve 4 is tightly fitted between the blades 3 and the cylinder 2. The shock-absorbing sleeve 4 is made of rubber and is bonded to the cylinder 2 and the blades 3. The thickness of the end of the shock-absorbing sleeve 4 connected to the cylinder 2 is greater than the thickness of the other end. The two ends are smoothly connected, which makes the stress distribution more uniform and can effectively absorb the vibration generated when the blades 3 rotate, thereby increasing the propulsion effect of the propulsion device.

[0027] The inner wall of the cylinder 2 is provided with a plurality of slots 5 penetrating both ends of the cylinder 2 along the circumferential direction. A connecting rod 6 is inserted into the cylinder 2. The side wall of the connecting rod 6 is provided with a limiting plate 7 that fits into the slot 5. The front end of the connecting rod 6 is connected to a hemisphere 8, and the rear end is connected to the drive motor 1. The hemisphere 8 and the diameter of the outer wall of the cylinder 2 form a guide head. The side wall of the connecting rod 6 located outside the cylinder 2 is provided with an annular groove 9. A rubber ring 10 with an outer wall diameter larger than the inner wall diameter of the cylinder 2 is fitted inside the annular groove 9. After the connecting rod 6 is inserted into the cylinder 2, the annular groove 9 is exposed in the cylinder 2. The rubber ring 10 is pressed into the annular groove 9 to fix the position of the connecting rod 6 and the cylinder 2 in the length direction.

[0028] Furthermore, the diameter of the outer wall of the rubber ring 10 is smaller than that of the cylinder 2. The end of the cylinder 2 that is in contact with the rubber ring 10 is connected to a ring 11 that is sleeved on the outside of the rubber ring 10, so that the rubber ring 10 is located inside the ring 11, reducing the impact of water flow on it and keeping it always within the annular groove 9, thus playing a limiting role.

[0029] Furthermore, the propeller is fitted with a cylinder 12, and multiple support rods 13 are connected between the cylinder 12 and the drive motor 1. Multiple annular baffles 14 are provided between the inner walls of the front end of the cylinder 12 to protect the propeller and make the wake field more stable.
