[0002] The water jet propulsion system is a key component that powers aquatic robots, using the reaction force generated by jetting water to propel the robot forward in the water. If large debris enters the propulsion system directly, it may collide with the high-speed rotating impeller inside, causing impeller blade deformation, breakage, or wear, severely impacting the performance and lifespan of the propulsion system.

[0003] For example, Chinese utility model patent (CN217320723U) discloses a water jet propulsion device, including a water inlet pipe and an impeller chamber. The bottom end of the water inlet pipe is a water inlet and is detachably connected to the bottom plate of the ship, and the rear end is a water outlet and is detachably connected to the front end of the impeller chamber. A water jet pipe is detachably connected to the rear end of the impeller chamber. A propulsion shaft is provided inside the water inlet pipe.

To this end, we designed a water jet propulsion device for a water robot to provide another technical solution to the above technical problems. Utility Model Content

[0031] Example 1

[0032] Reference Figures 1-4 A water jet propulsion device for an aquatic robot includes a water jet propulsion body 1. The water jet propulsion body 1 is existing technology sold on shopping platforms and will not be described in detail here. The water jet propulsion body 1 is installed on the bottom of the aquatic robot.

[0035] The snap-fit ​​assembly 5 also includes a snap-fit ​​pin 14, a second sliding plate 15, a second guide plate 16, and a spring 17. Both ends of the bottom inner side of the fixed plate 10 are slidably connected to the snap-fit ​​pin 14, which snaps into the connecting pin 9. One end of the snap-fit ​​pin 14 is fixed to the second sliding plate 15, which is slidably connected to the fixed plate 10 and fits against the first sliding plate 12. The outer end of the snap-fit ​​pin 14 near the second sliding plate 15 is fixed to the second guide plate 16, which is slidably connected to the fixed plate 10.

[0036] The design of the snap-fit ​​component 5 enables quick disassembly and installation of the inlet 3 and the connecting cylinder 4, making the maintenance of the internal parts of the connecting cylinder 4 more convenient and faster.

[0037] The bottom of the first sliding plate 12 and one end of the second sliding plate 15 are both arc-shaped. The arc-shaped design allows the first sliding plate 12 to better compress the second sliding plate 15.

[0038] Example 2

[0039] Reference Figure 2 and Figure 5 A water-spraying propulsion device for an aquatic robot includes a cutting assembly 6 comprising a fixed frame 18, a waterproof motor 19, a transmission rod 20, a first bevel gear 21, a second bevel gear 22, a first rotating rod 23, a second rotating rod 24, and a blade 25. The fixed frame 18 is fixed to the inner side of the connecting cylinder 4, and the fixed frame 18 is located between the first protective net 7 and the second protective net 8. The waterproof motor 19 is fixed to the outer side of the connecting cylinder 4, and the transmission rod 20 is fixed to the output end of the waterproof motor 19. The transmission rod 20 is rotatably connected to both the fixed frame 18 and the connecting cylinder 4, and the transmission rod 20 is located inside the fixed frame 18.

[0040] A first bevel gear 21 is fixed to one end of the transmission rod 20. The first bevel gear 21 is located inside the fixed frame 18. The top and bottom of the first bevel gear 21 are meshed with a second bevel gear 22. A first rotating rod 23 is fixed inside the top second bevel gear 22. A second rotating rod 24 is fixed at the bottom of the bottom second bevel gear 22. The first rotating rod 23 and the second rotating rod 24 are rotatably connected. Both the first rotating rod 23 and the second rotating rod 24 are rotatably connected to the fixed frame 18. The first rotating rod 23, the second rotating rod 24, and the bottom second bevel gear 22 are also rotatably connected. Three blades 25 are fixed to the bottom of the outer sides of the second rotating rod 24 and the first rotating rod 23.

[0041] Through the design of the cutting component 6, the blade 25 can cut debris into small pieces, which are then intercepted by the second protective net 8, thus better protecting the impeller inside the water jet propulsion body 1 and ensuring the smooth entry and exit of water.

[0042] The following is the usage process of the water jet propulsion device for a water robot provided by this utility model: When the water jet propulsion device 1 is started, the impeller inside the water jet propulsion device 1 rotates, and water in the area enters the water jet propulsion device 1 through the water inlet 3, and is then sprayed backward through the water jet nozzle 2.

[0043] Water entering the inner side of inlet 3 first flows through the first protective net 7 and the second protective net 8. The first protective net 7 filters out larger impurities and controls the waterproof motor 19 to start through an external controller. The output end of the waterproof motor 19 drives the transmission rod 20 to rotate, thereby causing the first bevel gear 21, which is fixedly connected to the transmission rod 20, to rotate. Since the first bevel gear 21 is fixedly connected to the second bevel gear 22, the second rotating rod 24 and the first rotating rod 23, which are respectively fixedly connected to the two second bevel gears 22, rotate. The rotation of the second rotating rod 24 and the first rotating rod 23 drives the blades 25 on the outside of the first rotating rod 23 and the second rotating rod 24 to rotate, thereby causing the blades 25 to cut the water plants and plastic bags entering the inner side of the connecting cylinder 4. The second protective net 8 can intercept the debris after cutting, preventing the debris from colliding with the high-speed rotating impeller inside the water jet propulsion body 1.

[0044] When it is necessary to disassemble and replace the connecting cylinder 4, turn the screw 11 with an Allen wrench, so that the first sliding plate 12, which is threaded to the screw 11, moves to the top. At this time, the first sliding plate 12 no longer presses against the second sliding plate 15. Since the spring 17 is fixedly connected to the second guide plate 16, and the second guide plate 16 is fixedly connected to the second sliding plate 15, as the first sliding plate 12 moves, the locking pin 14 is reset under the action of the spring force of the spring 17, so that the locking pin 14 is no longer locked with the connecting pin 9. At this time, the connecting cylinder 4 can be separated from the water inlet 3, and the parts on the connecting cylinder 4 can be inspected and maintained.

[0045] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to specific implementations. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
