[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0027] See also Figure 1 - Figure 7 , an amphibious inspection robot includes a robot body 1, two deformation grooves 101 are provided on both sides of the robot body 1, and steering grooves 103 are provided at the bottom of the four deformation grooves 101, and support legs 2 are slidably connected in the four deformation grooves 101, and the four support legs 2 are inlaid with steering motors 23 at one end close to the adjacent steering groove 103, and the output shafts of the four steering motors 23 at one end away from the adjacent support legs 2 are fixedly connected to steering rods 22, and the four steering rods 22 are respectively located in the four steering grooves 103, and the adjacent sides of the tops of the two support legs 2 on the same side are fixedly connected with deformation shafts 3, and the deformation shaft 3 is rotatably connected to the robot body 1, and the two support legs 2 near the rear end of the robot body 1 are connected to deformation components on one side away from the deformation shaft 3, and the four steering rods 22 are connected to moving wheels 4 on one side away from the steering groove 103, and a rotating component is connected between the moving wheel 4 and the steering rod 22, and a flying component is provided on the inner side of the moving wheel 4, and a lifting component is connected to the bottom of the robot body 1.

[0028] like Figure 1 - Figure 7 As shown, the structure of an amphibious inspection robot in the present invention is similar to that of the existing amphibious inspection robot. The main improvement of the present invention is that the flying part and the walking part are integrated with each other, so as to avoid interference between the flying part and the walking part during the inspection, making the inspection operation of the inspection robot smoother. Figures 1 to 7As shown, when the amphibious inspection robot of the present invention is in use, when the robot body 1 is performing land inspection operations, the four moving wheels 4 roll on the ground to move forward for inspection. When it is necessary to perform high-altitude navigation inspection operations, the robot body 1 is lifted to a certain height by the lifting component, so that the moving wheels 4 are off the ground. At this time, the deformation shaft 3 and the two supporting legs 2 on the same side are driven to flip from the inside of the deformation groove 101 to the outside, so that the four moving wheels 4 are horizontally distributed around the robot body 1. Subsequently, the flying component inside the moving wheels 4 can drive the robot body 1 to fly into the air for high-altitude inspection navigation, realizing the machine The robot body 1 switches and transforms between land and air inspection operations, realizing the amphibious inspection operations of the robot body 1. The steering rod 22 is used for steering when the robot body 1 walks on land, and when the robot body 1 switches from land mode to flight mode, it is necessary to drive the steering rod 22 to rotate in advance through the steering motor 23 to the state where the moving wheel 4 is parallel to the side of the robot body 1, and lock the steering motor 23 to ensure that the moving wheel 4 is parallel to the ground when switching to flight mode. It should be noted that the amphibious inspection robot is a lightweight robot and can smoothly perform takeoff, navigation and inspection operations when switching to flight mode.

[0029] like Figure 1 - Figure 3 As shown, the deformation assembly includes a deformation motor 5, a drive rod 6, and a motor base 7. One end of the drive rod 6 is fixedly connected to the side of the rear support leg 2 of the robot body 1 away from the deformation axis 3. The other end passes through the robot body 1 and is fixedly connected to the output shaft of the deformation motor 5. The outer shell of the deformation motor 5 is fixedly connected to the motor base 7, and the motor base 7 is fixedly connected to the robot body 1. By activating the deformation motor 5, the drive rod 6 rotates outward, which drives the two support legs 2 on the same side to flip outward from the deformation slot 101 via the deformation axis 3, achieving the shape change of the robot body 1.

[0030] like Figure 4 - Figure 7As shown, the rotating assembly includes a connecting rod 8, a fixed block 9 and a sleeve 10. One end of the connecting rod 8 is fixedly connected to the end of the steering rod 22 away from the support leg 2 and away from the side of the robot body 1. The other end of the connecting rod 8 is fixedly connected to the fixed block 9. The sleeve 10 is sleeved with the fixed block 9 and is rotatably connected to the fixed block 9. The side of the fixed block 9 away from the steering rod 22 is fixedly connected to the front block ring 11, and the side of the fixed block 9 close to the support leg 2 is fixedly connected to the driving ring 12. The side adjacent to the front block ring 11 and the driving ring 12 are respectively slidably connected to the two sides of the fixed block 9. The outer wall of the sleeve 10 is fixedly connected to a number of spokes 13. The other ends of the several spokes 13 are fixedly connected to the inner spokes of the moving wheel 4. The outer side of the driving ring 12 is connected to the driving assembly. The moving wheel 4 is fixed to the sleeve 10 through a plurality of spokes 13 to form a wheel structure, and is movably mounted on the steering rod 22 through the fixed block 9 and the connecting rod 8. When the driving assembly drives the sleeve 10 and the moving wheel 4 to rotate forward through the driving ring 12, the position of the sleeve 10 and the fixed block 9 is restricted by the front block ring 11 and the driving ring 12, thereby preventing the rotational connection between the sleeve 10 and the fixed block 9 from falling off.

[0031] like Figure 4 - Figure 6 As shown, the drive assembly includes a drive motor 14 and a drive gear 15. Several tooth grooves 102 are defined on the outside of the drive ring 12. The housing of the drive motor 14 is fixedly connected to the side of the steering rod 22 near the drive ring 12. The output shaft of the drive motor 14 is fixedly connected to the drive gear 15, which meshes with the tooth grooves 102. When the drive motor 14 is activated, the drive gear 15 meshes with the tooth grooves 102 on the drive ring 12, driving the drive ring 12 and the sleeve 10 to rotate outside the fixed block 9. This, in turn, drives the mobile wheels 4 to rotate via the spokes 13, completing the mobile inspection of the robot body 1 on land.

[0032] like Figure 4 - Figure 7 As shown, the flight assembly includes a flight motor 16 and several flight blades 17. A motor cavity 901 is defined on the side of the fixed block 9 away from the connecting rod 8. The flight motor 16 is fixedly connected to the cavity 901. The output shaft of the flight motor 16 extends through the fixed block 9, facing away from the connecting rod 8, and is fixedly connected to the flight blades 17, which are evenly distributed on the output shaft of the flight motor 16. Activating the flight motor 16 within the cavity 901 of the fixed block 9 rotates the multiple flight blades 17, forming a flight fan structure. This, in conjunction with the flight assembly within the other three moving wheels 4, propels the robot body 1 into takeoff and performs aerial inspections.

[0033] like Figure 4 - Figure 6As shown, the spokes 13 are provided with beveled edges on both sides of the end away from the steering rod 22. The beveled edges on the outward-facing side of the spokes 13 allow the flying blades 17 to rotate at high speed and draw the air above downward, so that the air flow above can flow more smoothly from above the spokes 13 to below through the beveled edges, reducing the obstruction of the air flow by the spokes 13 during flight.

[0034] like Figure 1 - Figure 4 As shown, a protective net 18 is fixedly connected to the inner side of the spoke at the end of the moving wheel 4 away from the steering rod 22. The protective net 18 is located on the side of the plurality of flight blades 17 away from the steering rod 22. The protective net 18 is fixed to the inner wall of the outward end of the moving wheel 4 to block external debris, such as leaves and flying insects, during flight and cruising, preventing the debris from being transferred by the airflow to the flight blades 17 and causing damage to the flight blades 17.

[0035] like Figure 2 As shown, the lifting assembly includes an electric push rod 19 and an I-shaped support frame 20. The electric push rod 19 is embedded in the middle position of the bottom of the robot body 1. The output end of the electric push rod 19 faces the bottom of the robot body 1 and is fixedly connected to the I-shaped support frame 20. When the robot body 1 changes from land to air, the electric push rod 19 is driven to drive the I-shaped support frame 20 to move downward, thereby lifting the entire robot body 1 off the ground, so that the four moving wheels 4 are out of contact with the ground, and the deformation operation can be performed. When the navigating robot body 1 needs to land and transform into land mode, the I-shaped support frame 20 is extended downward by the electric push rod 19 to form a landing frame, ensuring that when the robot body 1 stops flying and the moving wheels 4 are deformed downward, the switching deformation from flight mode to land mode can be completed smoothly.

[0036] like Figure 2 As shown, the four ends of the I-shaped support frame 20 are fixedly connected to curved plates 21. The ends of the four curved plates 21 away from the I-shaped support frame 20 are bent and extended toward the robot body 1. When the electric push rod 19 retracts the I-shaped support frame 20 upward, the curved edges of the curved plates 21 at the four ends of the I-shaped support frame 20 abut against the bottom of the robot body 1. When walking on land, the curved plates 21 can block branches, vines, etc. on the ground to the outside, preventing them from getting caught on the ends of the I-shaped support frame 20.

[0037] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention.
