Description

Technical Field

[0001] This utility model relates to the field of underwater robot land walking technology, specifically a land walking unit applied to an underwater robot. Background Technology

[0002] Underwater robots need to frequently switch between land-based transport and underwater operation scenarios, and their land mobility directly affects the efficiency of operation deployment.

[0003] However, the core design of traditional underwater robots focuses on underwater propulsion systems and lacks dedicated land-based locomotion structures. They rely heavily on manual handling or external lifting equipment for land-based movement, resulting in slow, time-consuming, and labor-intensive movement. Furthermore, although some underwater robots are equipped with simple wheels, the locomotion mechanism has difficulty switching between water and land environments. During underwater operations, the exposed wheels generate additional water resistance, affecting propulsion efficiency. Therefore, there is an urgent need for a land-based locomotion system for underwater robots to solve these problems. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-5 The present invention provides a land-based walking part for an underwater robot, comprising a main body plate 1, a sealing shell 101 fixedly connected to the top surface of the main body plate 1, and an underwater robot body fixedly connected to the top surface of the main body plate 1, and further comprising: A mobile component is disposed between the main body plate 1 and the sealing shell 101 to assist the underwater robot body in walking on land. A switching component is provided, which is located between the main body plate 1 and the sealing shell 101, and is used to switch the moving component. The movable components facilitate the movement of the main body plate 1, thereby improving the convenience of the underwater robot body walking on land. At the same time, the switching components facilitate the switching control of the position of the movable components, thereby avoiding the drag effect on the underwater robot body when it moves in water.

[0016] Furthermore, the moving assembly includes multiple moving wheels 301, which are disposed on the inner wall of the clearance cavity 2. A sliding hole 302 is formed in the inner wall of the clearance cavity 2. A sliding column 303 is slidably connected to the inner wall of the sliding hole 302. A connecting frame 304 is rotatably connected to the surface of the sliding column 303. The moving wheels 301 are rotatably connected to the inner wall of the connecting frame 304. A clearance groove 307 is formed in the inner wall of the sliding hole 302. A sealing ring 308 is fixedly connected to the inner wall of the clearance groove 307. The inner wall of the sealing ring 308 is slidably connected to the surface of the sliding column 303. A limiting groove 305 is formed on the surface of the moving wheel 301. An anti-slip ring 306 is fitted onto the surface of the moving wheel 301 through the limiting groove 305. Through the moving assembly, the sliding column 303 moves, causing the connecting frame 304 and the moving wheel 301 to extend, thereby allowing the moving wheel 301 to... The auxiliary main body plate 1 is moved in conjunction with the connecting frame 304. The moving wheels 301 contact the ground, and the moving wheels 301 are rotatably connected to the connecting frame 304, thereby avoiding the large frictional resistance generated when the main body plate 1 is in direct contact with the ground. This improves the convenience of the underwater robot body on land. The setting of the clearance groove 307 and the sealing ring 308 works together to facilitate the sealing of the gap between the sliding column 303 and the sliding hole 302, preventing water from entering the interior of the sealing shell 101 through the gap between the sliding column 303 and the sliding hole 302 when the main body plate 1 is in water. The setting of the limiting groove 305 and the anti-slip ring 306 works together to facilitate the increase of the friction when the moving wheels 301 are in contact with the ground, thereby improving the stability of the underwater robot body on land.

[0017] Furthermore, the switching assembly includes a connecting plate 401, which is disposed between the main body plate 1 and the sealing shell 101. The upper ends of multiple sliding columns 303 are fixedly connected to the bottom surface of the connecting plate 401. Multiple electric telescopic cylinders 402 are fixedly connected to the top surface of the main body plate 1. The telescopic shafts of the multiple electric telescopic cylinders 402 are fixedly connected to the bottom surface of the connecting plate 401. A controller 403 is fixedly connected to the top surface of the main body plate 1. The controller 403 is electrically connected to the electric telescopic cylinders 402. Through the switching assembly, the multiple sliding columns 303 are positioned on the same plane by the connecting plate 401. At the same time, when the telescopic shafts of the electric telescopic cylinders 402 move, they drive the connecting plate 401 and the sliding columns 303 to move. The movement of the sliding columns 303 facilitates the switching control of the position of the moving wheel 301, so that the moving wheel 301 can retract into the cavity 2 in the water, avoiding resistance when the underwater robot moves in the water.

[0018] Furthermore, a storage battery 404 is fixedly connected to the top surface of the main body plate 1. The storage battery 404 is electrically connected to the controller 403 and the electric telescopic cylinder 402. The storage battery 404 facilitates the supply of power to the controller 403 and the electric telescopic cylinder 402 outdoors, thereby improving the convenience of switching the connection plate 401.

[0019] Working principle: During use, the sliding column 303 moves through the set moving components, causing the connecting frame 304 and the moving wheel 301 to extend. This allows the moving wheel 301 and the connecting frame 304 to cooperate with each other to move the auxiliary main body plate 1. The moving wheel 301 contacts the ground, and the moving wheel 301 and the connecting frame 304 are rotatably connected, thus avoiding the large frictional resistance generated when the main body plate 1 contacts the ground, thereby improving the convenience of the underwater robot body on the top surface of the main body plate 1 to walk on land.

[0020] Meanwhile, the switching component allows multiple sliding columns 303 to be positioned on the same plane via the connecting plate 401. At the same time, when the electric telescopic cylinder 402 moves its telescopic shaft, it drives the connecting plate 401 and the sliding columns 303 to move. The movement of the sliding columns 303 facilitates the switching control of the position of the moving wheel 301, so that the moving wheel 301 can retract into the cavity 2 when in water, avoiding resistance when the underwater robot moves in water.
