Description

Technical Field

[0001] The utility model relates to the technical field of omni-rotating propellers, in particular to a novel shaftless electric propeller. Background Art

[0002] In the current ship propulsion system, the full-rotation propeller is a common propeller, which is usually powered by a diesel engine or an electric motor to drive the gears and shaft system to rotate and drive the propeller to generate thrust. At the same time, the electric motor or hydraulic motor drives the rotary mechanism to drive the underwater mechanism to achieve a full 360° rotation, which can generate all-round thrust. Due to its flexibility and maneuverability, this type of propulsion system is widely used in ships and boats with high maneuverability requirements, such as tugboats, marine engineering ships, passenger ships and some special yachts.

[0003] Although the traditional full-rotation propulsion device performs well in terms of control flexibility and maneuverability, it also has significant disadvantages. Usually, the traditional device is driven by a variable frequency motor or a diesel engine. The prime mover is connected to the full-rotation input shaft through a coupling. The driving gear on the input shaft and the driven gear on the propeller shaft form a reduction gear pair. After the transmission of the gear pair and the shaft system, the propeller is finally driven to rotate to generate thrust. Although this design can change the propeller speed and thus adjust the thrust by adjusting the speed of the variable frequency motor or diesel engine, its problems such as low propulsion efficiency, high noise, strong vibration, and low reliability are still prominent.

[0004] Especially in shallow waters, the fixed length and rigid design of traditional propellers limit their adaptability. The current propellers cannot adjust their length according to changes in water depth, making it difficult to operate in shallow waters. This not only affects the maneuverability and controllability of the ship, but may also cause the propeller to contact the bottom of the water or obstacles, increasing the risk of equipment damage and maintenance costs. In addition, the noise and vibration of traditional propellers are more obvious in shallow waters, further affecting propulsion efficiency and control stability. Utility Model Content

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the specification of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Example:

[0032] Please see attached Figure 1 -Attached Figure 2 The utility model embodiment provides a novel shaftless electric propulsion device, comprising:

[0033] The propulsion assembly is used to provide the thrust required for the movement of the ship. The propulsion assembly includes a shell 1, which is installed at the bottom of the angle adjustment assembly. Multiple groups of magnetic stators 15 are fixedly connected inside the shell 1. The middle of the shell 1 is rotatably connected to the propeller blades 2. When the multiple groups of magnetic stators 15 are arranged inside the shell 1, the winding directions of two adjacent groups are opposite. The magnetic force is generated by supplying power to the magnetic stators 15. Due to the principle of attraction and holding of magnetic attraction, the propeller blades 2 can be driven to rotate, thereby driving the propeller blades 2 to rotate at a high speed in the middle of the shell 1 to generate thrust. The shell 1, the propeller blades 2 and the magnetic stator 15 together constitute a rim motor. The working principle and implementation method are all existing technologies, which will not be described in detail here.

[0034] Please see attached Figure 1 and attached Figure 3 , an angle adjustment component is used to adjust the vertical angle of the propulsion component. The angle adjustment component includes an annular sleeve 7, which is fixedly connected to the bottom of the connecting column 6. The middle part of the annular sleeve 7 is rotatably connected to the connecting seat 3, and the connecting seat 3 is fixedly connected to the top of the shell 1. The inside of the annular sleeve 7 is rotatably connected to the electric push rod 23, and the bottom end of the electric push rod 23 is rotatably connected to the top of the connecting seat 3; after the electric push rod 23 is powered, it can act on one side of the connecting seat 3. At this time, the connecting seat 3 can rotate along the axis connected to the annular sleeve 7. When the electric push rod 23 extends outward, the connecting seat 3 rotates to one side. Conversely, when the electric push rod 23 contracts, the connecting seat 3 rotates to the other side, thereby changing the inclination angle of the shell 1, and then adjusting the power output direction.

[0035] Please see attached Figure 1 and attached Figure 5The height adjustment component includes a mounting hoop 4, a main sleeve rod 5 is rotatably connected inside the mounting hoop 4, a connecting column 6 is slidably connected in the middle of the main sleeve rod 5, a propulsion component and an angle adjustment component are installed at the bottom of the connecting column 6, and the position of the propulsion component is adjusted by changing the position of the connecting column 6, thereby adjusting the height of the propeller as needed. The top of the main sleeve rod 5 is fixedly connected to a housing 8, the outer side of the housing 8 is fixedly connected to a motor 9, the output end of the motor 9 is fixedly connected to a U-shaped frame 10, the middle of the U-shaped frame 10 is rotatably connected to a connecting rod 11, and the bottom of the connecting rod 11 is rotatably connected to the top of the connecting column 6; when used in shallow water areas, the driving motor 9 works to drive the U-shaped frame 10 to rotate, at which time the connecting rod 11 will be affected by the U-shaped frame 10 and tilt, and at the same time push the connecting column 6, at which time the connecting column 6 will be squeezed and move downward in the middle of the main sleeve rod 5; conversely, when the motor 9 works and drives the U-shaped frame 10 to rotate upward, the connecting column 6 can be lifted upward, and the housing 1 also moves upward at the same time, thereby completing the adjustment of the position of the housing 1. The outer side of the mounting hoop 4 is fixedly connected to a mounting frame 22, and the mounting frame 22 is used to install the propeller on the ship.

[0036] Please see attached Figure 1 and attached Figure 4 , a full-rotation component is used to drive the entire propeller to rotate at a full angle. The full-rotation component includes a motor 2 16. The motor 2 16 is fixedly connected to the outside of the mounting hoop 4. The output end of the motor 2 16 is fixedly connected to a gear 17. The outside of the main sleeve rod 5 is fixedly connected to a gear ring 18. The gear ring 18 and the gear 17 are meshed with each other. When the horizontal direction of the shell 1 needs to be adjusted, the driving motor 2 16 can drive the gear 17 to rotate, and then drive the main sleeve rod 5 to rotate through the transmission of the gear ring 18, thereby driving the mounting hoop 4 and the shell 1 to rotate, thereby realizing the adjustment of the power output direction of the propeller.

[0037] Please see attached Figure 1 -Attached Figure 3 , a water channel 12 is provided at the outer edge of the shell 1, and the water channel 12 is composed of a water inlet end 13 and a water outlet end 14. The water inlet end 13 is provided at the inlet end of the shell 1, and the water outlet end 14 is provided at the water outlet end of the shell 1. When the ship is moving, part of the water flow will enter from the water inlet end 13, and then be discharged from the water outlet end 14. Under the effect of the shape of the water channel 12, the water flow movement can be accelerated, thereby carrying out the heat generated by the magnetic stator 15 and other components when they are working. The inner diameter of the water inlet end 13 is larger than the inner diameter of the water outlet end 14, and the inner diameter of the water channel 12 decreases in sequence from the water inlet end 13 to the water outlet end 14; under the effect of this shape, the water flow movement can be accelerated to solve the problem of heating of components such as the magnetic stator 15 when they are working.

[0038] Please see attached Figure 4The main sleeve rod 5 is fixedly connected with a rotating seat 19 on the outside, and an annular groove 21 is provided in the middle of the mounting hoop 4. The rotating seat 19 is rotatably connected inside the annular groove 21. The connection between the mounting hoop 4 and the main sleeve rod 5 is stabilized by the rotating seat 19 and the annular groove 21, thereby ensuring the normal use of the propeller. A protective shell 20 is fixedly connected with the top of the mounting hoop 4, and the gear ring 18 and the gear 17 are installed inside the protective shell 20. The protective shell 20 is used to protect the gear ring 18, the gear 17 and other structures.

[0039] Working principle: When in use, the shell 1 is put underwater, and then the magnetic stator 15 is powered to generate magnetic force, thereby driving the propeller blades 2 to rotate at high speed in the middle of the shell 1 to generate thrust. When used in shallow water areas, the drive motor 9 works to drive the U-shaped frame 10 to rotate. At this time, the connecting rod 11 will be affected by the U-shaped frame 10 and tilt, and at the same time push the connecting column 6. At this time, the connecting column 6 is squeezed and moves downward in the middle of the main sleeve rod 5, thereby driving the shell 1 to move downward synchronously, thereby completing the adjustment of the position of the shell 1. Conversely, when the motor 9 works and drives the U-shaped frame 10 to rotate upward, the connecting column 6 can be lifted up, and the shell 1 is also folded up at the same time. In this way, the position of the shell 1 can be adjusted. When used in shallow water areas, the propeller can be prevented from contacting the bottom mud and obstacles, thereby avoiding damage to the propeller caused by collision;

[0040] Secondly, during the use of the thruster, the electric push rod 23 can also be powered to make the electric push rod 23 work. When the electric push rod 23 extends outward, it can act on the connecting seat 3, so that the connecting seat 3 can rotate along the axis inside the annular sleeve 7, thereby completing the change of the inclination angle of the shell 1, and then adjusting the power output direction;

[0041] Finally, when the horizontal direction of the shell 1 needs to be adjusted, the drive motor 16 can drive the gear 17 to rotate, and then drive the main sleeve rod 5 to rotate through the transmission of the gear ring 18, thereby driving the mounting hoop 4 and the shell 1 to rotate, thereby realizing the adjustment of the power output direction of the propeller.

[0042] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
