Description

Technical Field

[0001] The present invention belongs to the technical field of ship propulsion, and particularly relates to a vector propulsion device applicable to an ice area pod thruster. Background Art

[0002] An underwater vector propulsion device is an advanced propulsion system, which is widely used in equipment such as underwater vehicles and underwater robots.

[0003] For example, an underwater vector propulsion device disclosed in the patent publication number: CN213008674U includes: a connecting plate, angle adjusting mechanisms are connected to both sides of the connecting plate, a steering mechanism is connected to the other side of the connecting plate, the angle adjusting mechanism is used for the two-sided swing of the thruster, and the steering mechanism is used for adjusting the swing direction of the adjusting mechanism, and an underwater vector propulsion device capable of completing various propulsion actions.

[0004] Although the above devices can complete various propulsion actions, there are certain defects in the use of the above devices. Its angle adjusting mechanism realizes the two-sided swing of the thruster through a linkage mechanism. However, when the angle adjusting mechanism adjusts the thruster to a certain direction, the following situation is likely to occur: when navigating in an ice area, due to the existence of a large number of floating ice, the floating ice will collide with the thruster to generate mutual forces of different sizes. At this time, the angle adjusting structure formed by the linkage has poor stability, which is likely to cause the thruster to have an angle deviation, thereby affecting the accuracy of the propulsion direction. In view of this, the present invention is specifically proposed. Summary of the Invention

[0005] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to solve the above problems in the prior art, and provide a vector propulsion device applicable to an ice area pod thruster, so as to achieve the purpose of accurately adjusting the propulsion angle.

[0006] The present invention adopts the following technical solutions to achieve:

[0007] A vector propulsion device applicable to an ice area pod thruster includes a propulsion chamber, propulsion rods are symmetrically arranged on one side of the propulsion chamber, one end of the propulsion rod is connected with a screw propulsion device through a universal ball joint, angle adjusting components for the synchronous swing of the screw propulsion device are arranged at both ends of the propulsion chamber, the angle adjusting component includes a main gear plate and a secondary gear plate, driving motors are arranged inside both ends of the propulsion chamber, a quick-release cylinder is arranged at the output end of the driving motor, one end of the quick-release cylinder is connected with the main gear plate, one end of the secondary gear plate is connected with the screw propulsion device, the main gear plate and the secondary gear plate are in meshing transmission, and a quick-release component is arranged in the quick-release cylinder, and the quick-release component is movably connected with the main gear plate.

Limiting frames are provided on the main connecting plate and the secondary connecting plate. One end of the limiting frame is rotatably connected to the main connecting plate, and the other end of the limiting frame is rotatably connected to the secondary connecting plate. By using the limiting frame to provide the supporting force for the main connecting plate and the secondary connecting plate, the movement stability between the main gear plate and the secondary gear plate can be ensured.

DETAILED DESCRIPTION

[0026] In order to illustrate the technical solution and working principle of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention, but the present invention can also be implemented in other ways different from those described herein, and those skilled in the art can make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] See also Figures 1 - 6As shown in the figure, a vector propulsion device applicable to an ice area pod thruster includes a propulsion chamber 1. On one side of the propulsion chamber 1, propulsion rods 2 are symmetrically and fixedly installed. One end of the propulsion rod 2 is connected to a screw propulsion device 4 through a universal ball joint 3. Angle adjustment components 5 for the synchronous swing of the screw propulsion device 4 are arranged at both ends of the propulsion chamber 1. The angle adjustment component 5 includes a main gear plate 501 and a secondary gear plate 502. Driving motors 6 are arranged inside both ends of the propulsion chamber 1. The output end of the driving motor 6 is provided with a quick-release cylinder 7. One end of the quick-release cylinder 7 is connected to the main gear plate 501, and one end of the secondary gear plate 502 is connected to the screw propulsion device 4. The main gear plate 501 and the secondary gear plate 502 are in meshing transmission. A quick-release component 8 is arranged inside the quick-release cylinder 7, and the quick-release component 8 is connected to the main gear plate 501. Through the meshing transmission of the adjacent ends of the main gear plate 501 and the secondary gear plate 503 inside the angle adjustment component 5, when the driving motor 6 drives the main gear plate 501 to rotate, the secondary gear plate 503 can drive the screw propulsion device 4 to adjust the angle, thereby meeting the adjustment of the propulsion direction of this device. Moreover, an underwater flow velocity sensor (not shown in the figure) and a water depth sensor (not shown in the figure) are arranged inside the propulsion chamber 1, which can monitor the current water flow velocity and position height and provide data reference for navigation.

[0028] As Figure 3 and Figure 5 shown in the figure, the main gear plate 501 and the secondary gear plate 503 are in a mutually symmetrical arc structure. Rack teeth are arranged on the sides of the main gear plate 501 and the secondary gear plate 502 close to each other, and the rack teeth on the main gear plate 501 and the secondary gear plate 502 are meshed with each other. Main connecting plates 502 and secondary connecting plates 504 are respectively arranged on the sides of the main gear plate 501 and the secondary gear plate 503 far from each other. The main connecting plate 502 is connected to the quick-release component 8, and the secondary connecting plate 504 is connected to the screw propulsion device 4. The arc-shaped main gear plate and secondary gear plate can flexibly adjust the direction angle of the screw propulsion device. The main gear plate 501 and the secondary gear plate 502 are both made of polyamide material.

[0029] As Figure 4As shown, the quick-release assembly 8 includes a limit spring 801 disposed inside the quick-release cylinder 7. One end of the limit spring 801 is provided with a limit plate 802. One end of the main connection plate 502 is provided with a quick-release rod 803. The free end of the quick-release rod 803 is inserted into the quick-release cylinder 7 and abuts against the limit plate 802. The open end of the quick-release cylinder 7 is symmetrically provided with a docking hole 804 and a limit groove 805. The quick-release rod 803 is symmetrically provided with limit blocks 806, and the limit blocks 806 are engaged with the limit grooves 805. A waterproof rubber plate 807 is inserted into the docking hole 804 to facilitate the installation of the main connection plate 502. By inserting the quick-release rod 803 into the quick-release cylinder 7, at this time, the limit block 806 needs to be docked with the docking hole 804 and then inserted into the quick-release cylinder 7. At this time, the end of the quick-release rod 803 abuts against the limit plate 802, and then the main connection plate 502 is rotated. When the limit block 806 is aligned with the limit groove 805, the elastic force of the limit spring 801 can cause the limit block 806 to be inserted into the limit groove 805, thereby realizing the fixation of the main connection plate 502; when installing the sub-connection plate 504, the sub-connection plate 504 is installed into the screw hole (not shown in the figure) at the top of the screw propulsion device 4 through appropriate bolts, and then the main gear plate 501 and the sub-gear plate 502 are engaged. The rotation of the main gear plate 501 takes the axis of the quick-release rod 803 as the rotation axis, and the rotation of the sub-gear plate 502 takes the rotation center of the universal ball joint 3 as the rotation axis.

[0030] One end of the main connecting plate 502 is provided with a T-shaped hole 9, one end of the T-shaped hole 9 extends into the quick-release rod 803, and a limit frame 10 is arranged on the main connecting plate 502 and the sub-connecting plate 504. One end of the limit frame 10 is rotatably connected to the main connecting plate 502, and the other end of the limit frame 10 is rotatably connected to the sub-connecting plate 504. A limit rod 11 is arranged at one end of the limit frame 10. A threaded groove is provided at one end of the limit rod 11, and a limit nut 12 is threadedly connected to one end of the limit rod 11. The limit nut 12 is arranged in the T-shaped hole 9. An insertion rod 13 is arranged at the other end of the limit frame 10. A jack is provided on the sub-gear plate 502. The insertion rod 13 penetrates through the jack, and a threaded groove is also provided at one end of the insertion rod 13. A fixing nut 14 is threadedly connected to one end of the insertion rod 13 so as to connect the limit frame 10 with the main connecting plate 502 and the sub-connecting plate 504. At this time, the limit rod 11 needs to be inserted into the quick-release rod 803, and then the limit rod 11 is fixed by the limit nut 12. The insertion rod 13 at one end of the limit frame 10 is connected to the insertion rod 13 through the fixing nut 14, so as to realize the fixation of the sub-gear plate 502, and then the main gear plate 501 and the sub-gear plate 502 are fixed. Moreover, the axis of the limit rod 11 is the same as the axis of the quick-release rod 803, and the axis of the insertion rod 13 is on the same vertical line as the rotation axis of the universal ball joint 3. Thus, when the main gear plate 501 and the sub-gear plate 502 are engaged, on the basis of increasing the connection stability between the main gear plate 501 and the sub-gear plate 502, it can be ensured that the limit frame 10 does not affect the engagement between the main gear plate 501 and the sub-gear plate 502.
