Description

Technical Field

[0001] The invention relates to the technical field of cycloid propellers, and in particular to a cycloid propeller with adjustable eccentricity and an adjustment method. Background Art

[0002] The cycloid propeller consists of a group of blades, which are usually arranged in the middle of the hull, extending vertically from the hull (at a certain angle when using two propellers) into the water and moving in a circular motion around the center of the propeller and the axis perpendicular to the hull. While the blade group is moving in a circular motion, it also rotates around its own axis.

[0003] However, the spacing of the blade array of the existing cycloid propeller is generally not convenient for realizing flexible and synchronous omnidirectional adjustment. Although the direction of the blade can be adjusted autonomously, in actual use, when the spacing between the blades is sometimes different, it is generally necessary to customize in advance, which is not convenient for realizing flexible and fast adjustment. In addition, some existing small cycloid propellers are also not convenient for flexible and fast installation on the hull, because the cycloid propeller is generally installed at the stern by bolts, which makes it inconvenient for the heavy cycloid propeller to align with the threads between the mounting seat at the stern. Therefore, a cycloid propeller with adjustable eccentricity is proposed. Summary of the invention

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. The "up, down, left, right, front, and back" mentioned in the text are all based on the directions in the drawings. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of the present invention.

[0031] The embodiment of the present invention provides.

[0032] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.

[0033] See also Figure 1-7 , the present invention provides a cycloid propeller with adjustable eccentricity, comprising: a mounting seat 1, a connecting seat 2, an equipment seat 3, and an equipment seat 3;

[0034] The mounting seat 1 includes: a pancake-shaped mounting base plate 13, a spring 15, a sliding column 16, a connecting rod 17, and a clamping block 18. The mounting base plate 13 is evenly distributed with threaded holes. An annular boss 14 is provided in the center of the mounting base plate 13. The spring 15 and the sliding column 16 are coaxially assembled in the annular boss 14 from the inside to the outside. The sliding column 16 is slidably set in the annular boss 14, and one end of the sliding column 16 extends out of the annular boss 14. A snap-fit ​​assembly is provided between the mounting seat 1 and the connecting seat 2. There are four connecting rods 17, which are distributed on the outer peripheral wall of the sliding column 16 at one end of the annular boss 14 at equal intervals and the same height. One end of the connecting rod 17 is hinged to the outer peripheral wall of the sliding column 16. The connecting rod 17 moves away from and close to the sliding column 16 radially along the sliding column 16 with the hinge point as the fulcrum; the other end of the connecting rod 17 is hinged to the clamping block 18. Figure 2As shown, when not installed, the connecting rod 17 with the block 18 is in a drooping state, hanging on the side wall of the sliding column 16; Figure 3 As shown, the connecting rod 17 with the clamping block 18 can be unfolded to form a cross shape, which is also the shape after the mounting seat 1 and the connecting seat 2 are assembled.

[0035] A circular concave platform is provided at the center of the connecting seat 2, and a circular groove 19 is provided at the bottom center of the circular concave platform for one end of the sliding column 16 to penetrate, and four grooves 20 are provided around the circular groove 19 along the radial direction of the circular concave platform, and the four grooves 20 form a cross shape, and one end of the groove 20 extends to the side wall of the circular concave platform to form a groove cavity 21. Each clamping block 18 is slidably arranged in the groove 20 on one side thereof, and the clamping block 18 can slide into the groove cavity 21 along the groove 20 and engage with the groove cavity 21.

[0036] When the mounting seat 1 and the connecting seat 2 are mutually engaged, the arc-shaped boss at the opening of the circular concave platform will be engaged with the annular boss 14, and the block 18 will be aligned and placed in the groove 20, and the connecting seat 2 will continue to be pushed up. Due to the hinged setting of the connecting rod 17, it will move in the direction away from the sliding column 16, thereby pushing the block 18 to slide along the groove 20 until the block 18 is stuck in the groove cavity 21, and the connecting seat 2 is pushed up in place, which will fix the relative position between the mounting seat 1 and the connecting seat 2. At this time, the threaded holes on the periphery of the mounting seat 1 and the connecting seat 2 will correspond to each other, which will facilitate the installation of the bolts and facilitate the connection and installation of the equipment. Due to the gravity and the elastic force of the spring 15, the lower end of the sliding column 16 in the annular boss 14 will fit and conflict with the lower inner wall of the circular groove 19, which can enhance the connection stability after the mounting seat 1 and the connecting seat 2 are assembled.

[0037] The equipment base 3 includes a slide rail 4, a slider 5, a rotating motor 6, a rotating disk 7, and a connecting rod 8.

Two slide rails 4 are arranged in parallel to form a set of slide rails. Four sets of slide rails are arranged on the inner bottom surface and the inner top surface of the equipment base 3. The four sets of slide rails are arranged in a cross shape. The four sets of slide rails are arranged along the radial direction of the equipment base 3, such as Figure 6The slider 5 is shown in the space formed by the relatively arranged slide rails 4. On the inner top surface of the equipment seat 3 between the two slide rails 4 of the slide rail group, positioning grooves 9 are arranged radially and spaced apart from each other along the equipment seat 3. The spacing distance between the positioning grooves is set according to the position distribution of each blade under different eccentricities of the cycloid propeller. The position distribution data of the blades can be obtained through multiple groups of experiments, and the experimental data can be fitted by computer technology, or segmented adjustment operation can be performed to obtain the position data of the slider corresponding to each blade under the target eccentricity, and then determine the spacing distance between the positioning grooves. The connecting rod 8 is an elastic component or a telescopic component. The connecting rod 8 is arranged along the radial direction of the equipment seat 3. One end of the connecting rod 8 is hinged to the slider 5, and the other end is hinged to the edge of the rotating disk 7. The rotating motor 6 rotates the rotating disk 7 through the connecting rod 8 to drive the slider 5 to reciprocate along the radial direction of the equipment seat 3 in the space formed by the relatively arranged slide rails 4. The slider 5 includes: a second rotating motor 51, a push rod motor 52, and a push rod 53. The push rod motor 52 pushes the push rod 53 to engage with the positioning groove 9 to limit the movement of the slider 5. The mounting end of the blade 12 passes through the bottom surface of the equipment base 3 and is coaxially connected to the output shaft of the second rotary motor 51 in the slider 5, and moves with the slider 5. The mounting end of the blade 12 includes a chuck 10, and a mounting plate 11 is fixedly mounted on the lower end of the chuck 10 by bolts, and the blade 12 is fixedly connected to the lower end surface of the mounting plate 11.

The slider 5 is in the space formed by the relatively arranged slide rail 4 group, and the mounting end of the blade 12 passes through the bottom surface of the equipment seat 3 and is fixedly connected to the slider 5, and moves with the slider 5. When the rotating motor 6 works to drive the rotating disk 7 to rotate, the slider 5 can be driven to reciprocate along the radial direction of the equipment seat 3 through the connecting rod 8, so that it is convenient to control the rotation of the rotating disk 7 through the rotating motor 6, and then drive the connecting rod 8 to rotate, so that the connecting rod 8 can drive the four sliders 5 to slide close to or away from each other in their respective slide rails 4, and then drive the movement of the blade 12. After the movement is completed, the push rod 53 at the output end of the push rod motor 52 can be mutually positioned with the positioning groove 9 opened along the radial interval of the equipment seat 3, and then further accurately positioned to improve the stability of use. At the same time, the telescopic push rod 53 connected to the output end of the push rod motor 52 and the positioning groove 9 opened on the inner wall of the bottom surface of the equipment seat 3 are mutually positioned, and the elastic connecting rod 8 is set, The function of synchronous adjustment of the distance of some blades can be realized. The rotation of the blades 12 can also be flexibly controlled and adjusted by the second rotating motors 51 in the respective corresponding sliders 5.
