Description

Technical Field

[0001] This invention relates to the field of propulsion technology, and specifically to an improved energy-saving shaftless rim propulsion device. Background Technology

[0002] Friction thrusters, as a highly efficient propulsion device, are widely used in ships, underwater robots, and other equipment. In existing friction thrusters, the propeller blades are typically fixedly connected to the rotor. When the propeller blades are damaged or need to be replaced with different specifications for different operating conditions, the disassembly and assembly process is complex, resulting in high maintenance costs.

[0003] Meanwhile, the connection between the propeller blades and the rotor in traditional rim propulsion systems often has protrusions or depressions, which damages the integrity of the rotor surface and generates additional water flow resistance during propulsion, affecting propulsion efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an improved energy-saving shaftless rim propeller in order to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention provides the following technical solution: An improved energy-saving shaftless rim propeller includes a stator, a rotor disposed inside the stator, and a plurality of propeller blades disposed inside the rotor. The propeller blades are detachably connected to the inside of the rotor. Each propeller blade includes a body and an arc-shaped connecting piece. The body is connected to the inside of the rotor through the connecting piece, and after the connecting piece is connected to the rotor, the surface of the connecting piece and the surface of the rotor are located on the same circumferential surface.

[0006] Furthermore, a fixing groove is provided on the inner side of the rotor, and the connecting piece is fixedly connected in the fixing groove.

[0007] Furthermore, the connecting piece has several first fixing holes, and the rotor has a second fixing hole. After the connecting piece is placed in the fixing groove, the first fixing holes and the second fixing holes form a connecting hole. The screw passes through the second fixing hole and is connected to the first fixing hole to fix the connecting piece in the fixing groove.

[0008] Furthermore, the axial direction of the first fixing hole is parallel to the front end face of the connecting piece, and the axial direction of the second fixing hole is parallel to the front end face of the rotor.

[0009] Furthermore, the axial direction of the first fixing hole is perpendicular to the front end face of the connecting piece, and the axial direction of the second fixing hole is perpendicular to the front end face of the rotor.

[0010] The beneficial effects are: The propeller blades in this invention are detachably connected to the inside of the rotor. When the propeller blades are damaged or need to be replaced, they can be easily disassembled and assembled, reducing maintenance costs and operational difficulties. The propeller blades are connected to the rotor through an arc-shaped connecting piece, and after connection, the surface of the connecting piece and the surface of the rotor are located on the same circumferential surface, ensuring the integrity of the rotor surface, reducing water flow resistance during propulsion, and improving propulsion efficiency.

[0011] The connecting piece is fixed to the rotor by screws through the first and second fixing holes, which ensures a reliable connection and convenient assembly and disassembly. The axial direction of the first and second fixing holes can be selected according to actual needs to adapt to different installation requirements and stress conditions. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0016] This invention provides, for example Figure 1As shown, the rim propulsion device disclosed in this invention includes a stator 1, a rotor 2 disposed inside the stator 1, and a plurality of propeller blades 3 disposed inside the rotor 2, wherein the propeller blades 3 are detachably connected to the inside of the rotor 2.

[0017] like Figure 2 , Figure 4 As shown, the propeller blade 3 includes a body 31 and an arc-shaped connecting piece 32; the body 31 is connected to the inner side of the rotor 2 through the connecting piece 32, and after the connecting piece 32 is connected to the rotor 2, the surface of the connecting piece 32 and the surface of the rotor 2 are located on the same circumferential surface.

[0018] A fixing groove 21 is provided on the inner side of the rotor 2, and the connecting piece 32 is fixedly connected in the fixing groove 21. The shape of the fixing groove 21 is adapted to the connecting piece 32 to ensure that the connecting piece 32 can be accurately placed and fixed.

[0019] like Figure 3 As shown, the connecting piece 32 has several first fixing holes 321, and the rotor 2 has a second fixing hole 22. After the connecting piece 32 is placed in the fixing groove 21, the first fixing holes 321 and the second fixing holes 22 form a connecting hole 4. The screw 5 passes through the second fixing hole 22 and is connected to the first fixing hole 321 to fix the connecting piece 32 in the fixing groove 21.

[0020] In this embodiment, the first fixing hole 321 can be a threaded hole, and the second fixing hole 22 can be a through hole. The screw 5 passes through the second fixing hole 22 and is threadedly connected to the first fixing hole 321 to fix the connecting piece 32 to the rotor 2.

[0021] In this embodiment, the axial directions of the first fixing hole 321 and the second fixing hole 22 are parallel to each other, with the axial direction of the first fixing hole 321 being parallel to the front end face of the connecting piece 32, and the axial direction of the second fixing hole 22 being parallel to the front end face of the rotor 2. This arrangement is suitable for situations where there is ample axial space, facilitating installation. Example

[0022] like Figure 5 As shown, the structural difference between this embodiment and Embodiment 1 lies in the positions of the first fixing hole 321 and the second fixing hole 22. In this embodiment, the axial direction of the first fixing hole 321 is perpendicular to the front end face of the connecting piece 32, and the axial direction of the second fixing hole 22 is perpendicular to the front end face of the rotor 2. This arrangement is suitable for situations with ample radial space and facilitates installation.

[0023] In practical use: During installation, the rim propeller of this invention is first installed by placing the connecting piece 32 of the propeller blade 3 into the fixing groove 21 of the rotor 2, aligning the first fixing hole 321 with the second fixing hole 22. Then, the screw 5 is passed through the second fixing hole 22 and screwed into the first fixing hole 321, completing the fixed connection between the propeller blade 3 and the rotor 2. When it is necessary to replace or repair the propeller blade 3, simply unscrew the screw 5 to remove the propeller blade 3 from the rotor 2, making the operation simple and convenient.
