[0022] To facilitate understanding of how this multi-degree-of-freedom screw-driven amphibious special operation platform can achieve driving and operation on the surface, underwater, underwater, and in combined water and land areas, the following detailed structure and working principle are described:

[0023] Frame 1 structure: Figure 2 As shown, the vehicle frame 1 in this embodiment is a rectangular frame structure. Considering the installation of the four sets of internal drive rollers 5 and the silo 4, four sets of powered side roller brackets 8 are installed at the four corners of the bottom of the frame 1, and four sets of unpowered side roller brackets 9 are installed in the middle. The unpowered side roller brackets 9 pass through the bottom of the vehicle body and form two silo fixing rings 10 in the middle of the bottom of the vehicle body. The silo 4 is fixedly mounted in the middle of the bottom of the frame 1 via the silo fixing rings 10; the four sets of internal drive rollers 5 are fixedly connected to the unpowered side roller bracket 9 on one side and rotatably connected to the powered side roller bracket 8 on the other side.

[0024] External structure of the inner drive roller 5: The inner drive roller 5 is the main moving component of the working platform. Through the operation of the four sets of inner drive rollers 5, the working platform can move forward and backward in water and on land, and provide power for turning and lateral movement on land. Specifically, Figure 3 and Figure 4As shown, the four groups of inner drive rollers 5 in this embodiment have the same structure, and all include a cylindrical roller 11, the interior of the roller 11 is hollow, and a spiral blade 12 is provided on the outer surface of the roller 11. When the inner drive roller 5 runs at high speed in the water, the spiral blade 12 can form a propulsion force similar to a paddle blade. When the inner drive roller 5 runs at high speed on land, the spiral blade 12 can cut the ground or generate friction with the ground, thereby forming a grip to adapt to extreme conditions such as swamps and mudflats. It should be noted that: in this embodiment, two groups of inner drive rollers 5 are installed on the left side of the bottom of the frame 1, and the spiral blades 12 thereon have opposite rotation directions; two groups of inner drive rollers 5 are installed on the right side of the bottom of the frame 1, and the spiral blades 12 thereon have opposite rotation directions.

[0025] Connection and installation of inner drive roller 5: Figure 3 and Figure 4 As shown, the rollers 11 of the four sets of inner drive rollers 5 in this embodiment have a tapered connection end 13 formed at one end near the power-side roller bracket 8. A rotation connecting shaft 14 is mounted on the tapered connection end 13. The rotation connecting shaft 14 is rotatably connected to the power-side roller bracket 8 through a first support bearing 15. The inner drive roller 5 also includes a fixed connection shaft 16 connected to the unpowered side roller bracket 9.

[0026] The driving mode of the inner drive roller 5 is as follows: Figure 3 and Figure 4 As shown, a fixed connecting shaft 16 extends from the other end of the drum 11 into the interior thereof and is fixedly connected to a retaining frame 18 within the drum 11 via an adapter ring 17. A drive assembly is mounted within retaining frame 18 and is drivingly connected to the inner wall of the drum 11. The drive assembly includes a drive motor 19 fixedly mounted within retaining frame 18, a reducer 20 connected to the output end of the drive motor 19, and the output end of the reducer 20 is connected to the inner wall of the drum 11 via a coupling 21. A drive disc 22 is provided within the drum 11, mating with the coupling 21. The circumference of the drive disc 22 is fixedly connected to the inner wall of the drum 11.

[0027] When the drive motor 19 is powered by the battery in the compartment 4 and is started and stopped by the controller, after the drive motor 19 is running, it drives the roller 11 to rotate through the reducer 20, the coupling 21, and the drive disc 22; during the rotation of the roller 11, since the fixed connecting shaft 16 is fixedly connected to the roller bracket 9 on the unpowered side of the frame 1, the positions of the fixed connecting shaft 16, the adapter ring 17, and the retaining frame 18 do not change, and the roller 11 performs high-speed rotation on the fixed connecting shaft 16 and the powered side roller bracket 8.

[0028] Furthermore, as a preferred technical solution of this embodiment, Figure 2 、 Figure 3 and Figure 4As shown, considering the control and wiring issues of the drive components, in this embodiment, a motor controller 23 is installed on the retaining frame 18 to cooperate with the controller in the warehouse body 4 to realize the independent drive and independent control functions of the four sets of inner drive rollers 5. Since the working platform is an amphibious operation, the wiring needs to consider the waterproof and sealing issues. In this embodiment, a wiring hole is designed on the fixed connecting shaft 16, and the connection line is routed through the wiring hole to the outside of the inner drive roller 5. A watertight connector 7 is installed at the connection between the fixed connecting shaft 16 and the unpowered side roller bracket 9, thereby meeting the sealing wiring problem.

[0029] Furthermore, as a preferred technical solution of this embodiment, Figure 2 、 Figure 3 and Figure 4 As shown, since the working platform is an amphibious operation, the processing of the inner drive drum 5, the installation of the internal drive assembly, and the sealing performance are taken into consideration. In this embodiment, a sealing assembly is provided at the other end of the drum 11, and the drum 11 is rotatably mounted on the fixed connecting shaft 16 through the sealing assembly. The sealing assembly includes a driven end disc 25 rotatably mounted on the fixed connecting shaft 16 through a second support bearing 24. The driven end disc 25 is a circular plate body, which is bolted to the end surface of the other end of the drum 11, and a first sealing ring 26 is provided between the driven end disc 25 and the drum 11. A second sealing ring and a sealing cover 27 are provided on the outside of the driven end disc 25 at the corresponding position of the second support bearing 24. At the same time, a driving end disc 28 is installed at the end of the tapered connecting end 13 of the inner drive drum 5. The driving end disc 28 is a circular plate body, and a third sealing ring is provided on the side where the driving end disc 28 is connected to the tapered connecting end 13. The center of the outer portion of the driving end disc 28 is fixedly connected to the rotating connecting shaft 14.

[0030] Based on the above structural description, the multi-degree-of-freedom spiral drive amphibious special operation platform provided in this embodiment has the following working principle:
