Description

Technical Field

[0001] This utility model relates to the field of propeller technology, and more specifically, to a split-type marine propeller. Background Technology

[0002] In existing technologies, propellers typically adopt an integrated design concept. Even in split-type structures, the connection methods between their components are relatively fixed and simple. In actual use, when propeller blades are damaged, worn, or need to be removed, it is not possible to quickly and conveniently replace parts.

[0003] Traditionally, the main blades and slave blades are fixed by bolts, welding, or mechanical clamping. Under long-term seawater corrosion, high-speed operation, and alternating loads, these connection methods are prone to problems such as bolt corrosion, weld cracking, or clamping mechanism jamming. When it is necessary to remove the fixation, the corroded bolts are difficult to disassemble, and the damaged welds need to be cut.

[0004] As a precision fluid machinery component, the connection between the main blade and the driven blade of a propeller must ensure high precision in coaxiality, angular consistency, and surface fit. However, existing connection methods often require precise docking in a confined operating space, which places extremely high demands on the skill level of the operators. Utility Model Content

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides a split-type marine propeller, which has the following advantages:

[0018] 1. The disassembly assembly adopts a combination design of main propeller and fixed plate, realizing the modular structure of propeller. This allows marine propellers to be disassembled into independently replaceable parts without having to replace the entire propeller system. When a part of the propeller is damaged, only the damaged part needs to be replaced, without disassembling the entire propeller, which greatly reduces maintenance time and cost.

[0019] 2. The innovative design of the fastening components solves the problem of difficult connection and disconnection of traditional propellers. The fixing or disconnection of the propeller can be completed through simple operation steps, which greatly improves maintenance efficiency. The setting of the first spring provides pre-tightening force and buffer function to ensure that the components can smoothly transition during the connection process and reduce impact damage.

[0020] 3. The insertion component is designed with a precise positioning mechanism, which enables accurate positioning of the propeller during installation, ensuring the dynamic balance and working efficiency of the entire propeller system. The second spring provides necessary buffering, effectively absorbing impact force and protecting the connection structure in the vibration environment generated by the high-speed rotation of the propeller.

[0031] Please see Figures 1-5 A split-type marine propeller includes a fixed cylinder 1, on which a disassembly assembly is provided. The disassembly assembly includes a main propeller 2 and a fixed plate 3. The main propeller 2 is disposed on the fixed cylinder 1, and the fixed plate 3 is disposed on the main propeller 2. A secondary propeller 4 is inserted into the fixed plate 3. A fastening assembly is provided on the fixed plate 3 and the secondary propeller 4. The fastening assembly includes a fastening sleeve 5 and a fastening rod 6. The fastening sleeve 5 is fixedly installed on the fixed plate 3, and the fastening rod 6 is inserted into the secondary propeller 4 and the fixed plate 3. A fastening plate 7 is connected to the fastening rod 6.

[0032] A movable plate 8 is slidably connected to the fastening sleeve 5, a movable rod 9 is installed on the movable plate 8, and a connecting plate 10 is connected to the movable rod 9.

[0033] A rotating plate 11 is rotatably connected to the fastening sleeve 5. A fitting groove 12 is provided on the rotating plate 11. The fitting groove 12 is adapted to the connecting plate 10. A first spring 13 is provided between the moving plate 8 and the fastening sleeve 5.

[0034] The fastening sleeve 5 is threaded and connected to a threaded sleeve 14, and a sealing gasket 15 is provided between the threaded sleeve 14 and the fastening sleeve 5.

[0035] In this embodiment, when the paddle 4 needs to be replaced during use, the threaded sleeve 14 is rotated off the fastening sleeve 5 and then the moving plate 8 is slidably connected along the fastening sleeve 5. When the moving plate 8 slides, the first spring 13 between the moving plate 8 and the fastening sleeve 5 is stretched, so that when the moving plate 8 moves, it drives the moving rod 9 and the connecting plate 10 to move, so that the connecting plate 10 is removed from the rotating plate 11, thereby releasing the fixing process of the rotating plate 11. Then, the fitting groove 12 is rotated to the position corresponding to the connecting plate 10. At this time, the connecting plate 10 is released, so that under the action of the elastic potential energy of the first spring 13, the connecting plate 10 on the moving rod 9 is driven to fit into the fitting groove 12 of the rotating plate 11, thereby completing the fixing process of the rotating plate 11.

[0036] Please see Figure 4-6As an embodiment of a split marine propeller for inserting components: an inserting component is provided on the fastening sleeve 5. The inserting component includes a connecting rod 16 and a connecting block 17. The connecting rod 16 is slidably connected to the fastening sleeve 5, and the connecting block 17 is connected to the connecting rod 16. A second spring 18 is sleeved on the connecting rod 16, and the two ends of the second spring 18 are connected to the fastening sleeve 5 and the connecting block 17.

[0037] A fastening block 19 is connected to the connecting block 17, and a fastening groove 20 is provided on the fastening rod 6. The fastening groove 20 is adapted to the fastening block 19.

[0038] The rotating plate 11 has a rotating groove 21.

[0039] A rotating block 22 is slidably connected to the rotating groove 21, and the rotating block 22 is connected to the connecting block 17.

[0040] More specifically, when the rotating plate 11 rotates along the fastening sleeve 5, it causes the rotating block 22 to rotate along the rotating groove 21. As it moves, it causes the connecting rod 16 and the connecting block 17 to move, compressing the second spring 18 between the fastening sleeve 5 and the connecting block 17. This causes the connecting block 17 and the fastening block 19 to move, allowing the fastening block 19 to move out of the fastening groove 20 of the fastening rod 6, thus releasing the fastening rod 6. At this point, the fastening rod 6 can be removed along the fastening sleeve 5, the fixing plate 3, and the slave propeller 4, releasing the slave propeller 4. The slave propeller 4 can then be removed and replaced. After the operation is completed, the above operation is repeated in reverse to complete the fixing process between the main propeller 2 and the slave propeller 4.

[0041] In summary, during the use or operation of the overall equipment: When it is necessary to replace the paddle 4 blades, rotate the threaded sleeve 14 off the fastening sleeve 5 and then slide the moving plate 8 along the fastening sleeve 5. As the moving plate 8 slides, the first spring 13 between the moving plate 8 and the fastening sleeve 5 is stretched. This causes the moving rod 9 and the connecting plate 10 to move, allowing the connecting plate 10 to be removed from the rotating plate 11, thus releasing the fixing process of the rotating plate 11. Then, rotate the fitting groove 12 to the position corresponding to the connecting plate 10. At this time, release the connecting plate 10, so that under the action of the elastic potential energy of the first spring 13, the connecting plate 10 on the moving rod 9 is driven to fit into the fitting groove 12 of the rotating plate 11, thus completing the fixing process of the rotating plate 11.

[0042] When the rotating plate 11 rotates along the fastening sleeve 5, it causes the rotating block 22 to rotate along the rotating groove 21. As it moves, it causes the connecting rod 16 and the connecting block 17 to move. As it moves, it compresses the second spring 18 between the fastening sleeve 5 and the connecting block 17, causing the connecting block 17 and the fastening block 19 to move. This causes the fastening block 19 to move out of the fastening groove 20 of the fastening rod 6, thus releasing the fastening rod 6. At this point, the fastening rod 6 can be removed along the fastening sleeve 5, the fixing plate 3, and the slave propeller 4, releasing the slave propeller 4. The slave propeller 4 can then be removed and replaced. After the operation is completed, the above operation is repeated in reverse to complete the fixing process between the main propeller 2 and the slave propeller 4.

[0043] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
