It is composed only of a rim-type motor, a propeller, a water-lubricated bearing, and an energy-saving fairing. It has the characteristics of low noise, no transmission loss, and low resistance.

[0003] After searching, the publication number CN212435560U, application date 2020.06.02, discloses a circular electric propulsion device driven by an axial flux motor, including: a housing, an axial flux motor, a propeller and a bearing assembly. The utility model circular electric propulsion device uses an axial flux motor placed in the water to directly drive the propeller to rotate, eliminating the intermediate transmission equipment. The rotor and propeller assembly are supported by bearings placed in the water and transmit the thrust to the motor and the hull; the intermediate transmission loss between the motor and the propeller is reduced, the efficiency is improved, the propulsion system structure is simplified, and the noise and vibration are reduced.

[0004] However, it still has the following disadvantages in actual use:

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments 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. Specific embodiment 1

[0036] See also Figures 1 to 6 The utility model is a propeller that is easy to disassemble and assemble blades, including a shell 1 and a radial bearing mechanism 103 arranged at the center position of the inner wall thereof, the inner wall of the radial bearing mechanism 103 is evenly spaced with partitions 104 along the circumferential direction, the front end of the outer wall on one side and the rear end of the outer wall on the other side of the partition 104 are both provided with movable grooves 1041, a blade flange 105 is installed between adjacent partitions 104, a through groove 1053 is opened at the inner center position of the blade flange 105, and a limiting component 2 is arranged inside the movable groove 1041; the limiting component 2 includes a push plate 201 and a connecting column 2011 fixedly connected to the center position of the inner wall thereof, the other end of the connecting column 2011 passes through the through hole on the outer wall of the movable groove 1041 and is connected to the movable plate 202.

[0037] Specifically, a stator mechanism 101 is provided at the inner center of the housing 1, a rotor mechanism 102 is provided on the outer side of the stator mechanism 101, a radial bearing mechanism 103 is provided on the outer side of the rotor mechanism 102, a limiting groove 1051 is provided at the front end of the outer wall on one side and the rear end of the outer wall on the other side of the blade flange 105, both sides of the upper surface of the blade flange 105 are fixedly connected with a plug rod 1052, a blade 106 is installed on the inner wall of the blade flange 105, and slots are provided on both sides of the bottom of the blade 106 1061, a card slot 1062 is set at the bottom center position of the blade 106, and a connecting rod 204 is fixedly connected to one end surface of the movable plate 202 at uniform intervals from front to back, and the other end of the connecting rod 204 passes through a through hole on one end surface of the fixed plate 203 and is connected to the limit plate 206. A return spring 205 is sleeved on the outer side of the outer wall of the connecting rod 204, and the return spring 205 is located between the fixed plate 203 and the limit plate 206. The outer wall of the fixed plate 203 is fixed on the inner wall of the movable groove 1041.

[0038] Furthermore, the stator mechanism 101, the rotor mechanism 102, the radial bearing mechanism 103, etc. are all prior arts, so they will not be elaborated here. The movable plate 202 and the push plate 201 are connected by the connecting column 2011, which plays a role of connecting transmission. The insert rod 1052 is inserted into the interior of the slot 1061, and the movable plate 202 and the limit plate 206 are connected by the connecting rod 204, which plays a connecting role. Under the elastic performance of the reset spring 205, the limit plate 206 can be driven to move, and the cross-section of the slot 1062 is T-shaped.

[0039] The operation process of this embodiment is as follows: first, the front and rear groups of push plates 201 located outside the front and rear end surfaces of the partition 104 are pushed along the openings on the front and rear end surfaces of the partition 104, and the inner wall of the push plate 201 is connected to the movable plate 202 through the connecting column 2011. Therefore, when the push plate 201 is moved by force, the movable plate 202 is driven to move under the action of the connecting column 2011, and the inner wall of the movable plate 202 is connected to the limit plate 206 through the connecting rod 204. Therefore, when the movable plate 202 moves, the limit plate 206 is driven to move under the action of the connecting rod 204, and the reset spring 202 is squeezed. 05, then insert the blade flange 105 between the two adjacent partitions 104, and then stop applying force to the push plate 201. At this time, the limit plate 206 is ejected under the elastic performance of the reset spring 205, and is inserted into the limit groove 1051 set in the front and rear of the outer walls on both sides of the blade flange 105, so as to limit the blade flange 105 and complete the installation. Similarly, multiple sets of blade flanges 105 and blades 106 are installed in the shell 1 in turn, which makes it convenient for the staff to quickly disassemble and assemble the blade flange 105 and the blade 106, saving time and effort and improving work efficiency. Specific embodiment 2

[0041] See also Figure 5 , 6 7. Based on the specific embodiment 1, what is different from the first embodiment is that: a mounting assembly 3 is provided, and the mounting assembly 3 includes a left clamping plate 301 and a right clamping plate 302 symmetrically arranged on one side of the through slot 1053 about the center position thereof, the middle part of the left clamping plate 301 is hingedly connected to the middle part of the right clamping plate 302, and a compression spring 303 is fixedly connected between the opposite end surfaces of one side of the left clamping plate 301 and the right clamping plate 302, which solves the existing problem that the blade and the blade tip flange cannot be separated, so when the blade is damaged, the blade and the blade tip flange need to be replaced as a whole, resulting in a waste of resources.

[0042] Specifically, a connecting plate 304 is fixedly connected at the bottom front end of the left card plate 301 and the bottom rear end edge of the right card plate 302, and a rotating shaft 305 is rotatably connected to the inner center position of the connecting plate 304. The front and rear ends of the rotating shaft 305 are respectively fixed on the inner walls of the through groove 1053, and a push block 306 is fixedly connected to the bottom end of the connecting plate 304.

[0043] Furthermore, the left card plate 301 and the right card plate 302 have the same shape and size, and their cross-sections are both L-shaped. Under the action of the connecting plate 304, the left card plate 301 and the right card plate 302 can be connected to the push block 306 to play a role in connecting transmission. The rotating shaft 305 can limit and rotate the connecting plate 304, and the left card plate 301 and the right card plate 302 can move under the action of the elastic properties of the compression spring 303.

[0044] The operation process of this embodiment is as follows: when the blade 106 is damaged and needs to be replaced, after the blade flange 105 and the blade 106 on its surface are removed by the limiting assembly 2, the push blocks 306 on both sides of the bottom of the blade flange 105 are pushed toward the center position, and the tops of the two adjacent push blocks 306 are respectively connected to the left card plate 301 and the right card plate 302 through the connecting plate 304, and the front and rear adjacent connecting plates 304 are limited in rotation by the rotating shaft 305. Therefore, when the two push blocks 306 are forced to move toward the center, the left card plate 301 and the right card plate 302 will be driven to move toward the center under the action of the connecting plate 304 and the rotating shaft 305, and the compression spring 303 will be squeezed. At this time, the left card plate 301 and the right card plate 302 can be cancelled. The plate 302 and the limiting effect of the slot 1062 at the bottom of the blade 106, the blade 106 can then be removed from the surface of the blade flange 105 and replaced. During the replacement process, the insertion rod 1052 is first inserted into the slot 1061 at the bottom of the blade 106, and then the left card plate 301 and the right card plate 302 are inserted into the slot 1062, and the force on the push block 306 is canceled. At this time, under the elastic performance of the compression spring 303, the left card plate 301 and the right card plate 302 are rebounded to the initial position, and play a limiting role with the slot 1061 at the bottom of the blade 106, thereby realizing the separation of the blade flange 105 and the blade 106, facilitating the replacement of the blade 106 separately, and reducing resource waste.
