[0062] Example 2

[0063] The substation autonomous obstacle inspection robot provided in the first embodiment is further optimized. Specifically, Figures 1-12 A central driving roller 421 is connected to the middle of the wheel deformation shaft 42, and the central driving roller 421 rotates at the center of the winding control box 411. A driving steel wire 422 is wound around the outer wall of the central driving roller 421.

[0064] The winding control box 411 is internally connected to a driven wire roller 424 that is equidistantly arranged in a ring shape, and a driven wire 425 is wound around the middle of the driven wire roller 424. The driven wire 425 slides through the outside of the winding control box 411 at one end away from the driven wire roller 424. High-pressure springs 426 are fitted at the positions where both ends of the driven wire roller 424 are connected to the winding control box 411.

[0067] Example 3

[0068] The substation autonomous obstacle inspection robot provided in the first or second embodiment is further optimized. Specifically, Figures 1-12 As shown, the wheel body positioning portion 6 includes an embedded receiving groove 61 opened on one side of the inner wall of the wheel groove 31, and a rotating movable groove 62 is opened at the bottom of the inner side of the embedded receiving groove 61. The top surface and side surface of the inner wall of the rotating movable groove 62 are connected with an electromagnetic piece 63. A positioning slide rod 64 is embedded in the embedded receiving groove 61, and a hinge rod 65 is connected to the lower middle part of the positioning slide rod 64. The hinge rod 65 is hinged between the rotating movable groove 62 and the embedded receiving groove 61, and an electromagnetic block 66 is connected to the bottom end of the positioning slide rod 64. The electromagnetic block 66 is located inside the rotating movable groove 62. The rotating movable groove 62 and the electromagnetic piece 63 are magnetically attracted and connected when the power is on. The rotating movable groove 62 and the electromagnetic piece 63 repel each other when the power is on. The magnetic attraction connection between the rotating movable groove 62 and the electromagnetic piece 63 drives the positioning slide rod 64 to rotate and slide to the inside of the positioning slot 415.

[0069] A wheel body positioning part 6 is provided on one side of the inner wall of the wheel groove 31, which can automatically complete the fixation of the double-rod sleeve shaft 4 and the universal seat 3 when the wheel body is deformed into four legs, thereby avoiding the rotation of the four legs that can be deformed into the wheel body and improving the walking stability of the four-legged inspection robot. The wheel body positioning part 6 and the double-rod sleeve shaft 4 are electrically connected and can automatically complete automatic locking through the switching of the four legs and the wheel body.

[0070] The use process of the substation autonomous obstacle-crossing inspection robot provided by the present invention is as follows:

[0071] Start the inspection body 1, and connect the control center 11 inside the inspection body 1 to the external control mechanism through electrical signals. The program set up in the control center 11 can be started by the external program, driving the inspection body 1 to drive the walking wheel feet 2 to perform various actions, thereby realizing the movement of the inspection robot.

[0072] When the inspection body 1 moves, the inspection body 1 will drive the walking wheel feet 2 to rotate through the internal driving mechanism. When the walking wheel feet 2 rotate, they will cooperate with the driving section of the large arm 21 and the second section of the elastic arm 22 to cooperate with each other to realize the four-legged movement of the inspection body 1.

[0073] When the inspection body 1 needs to move at high speed, the deformation motor 423 is started, and the deformation motor 423 drives the wheel deformation shaft 42 to rotate. The rotation of the wheel deformation shaft 42 drives the central driving roller 421 to rotate. The rotation of the central driving roller 421 reels the driving wire 422. The retraction of the driving wire 422 pulls the two sets of leg spring steels 51 to retract each other.

[0074] During the contraction of the standing leg spring steel 51, since its two ends are hinged by the lateral assembly 53 (the lateral assembly 53 is made of the same material as the standing leg spring rod), the contraction of the standing leg spring steel 51 will press the lateral assembly 53 to deform, causing the lateral assembly 53 to form a ring with the standing leg spring steel 51.

[0075] It should be noted that: since the central driving roller 421 rotates synchronously to wind the two sets of driving wires 422 connected to the leg spring steels 51, the two sets of leg spring steels 51 will move synchronously, so that the center point of the wheel body formed by the leg spring steels 51 and the lateral assembly 53 coincides with the rotation axis 41, ensuring the stability of the wheel body rotation.

[0076] When the standing leg spring steel 51 shrinks and slides, since the two ends of the standing leg spring steel 51 are connected with fixing bars 54 to limit the sliding inside the deformation shrinkage hole 414, the deer leg spring steel can slide stably and firmly outside the retracting control box 411.

[0077] It should be noted that the power required by the deformation motor 423 is transmitted through the connection between the contact ring 35 and the power receiving ring 413. After receiving the power, the power receiving ring 413 passes through the wire inside the wheel deformation shaft 42 to transmit the power to the deformation motor 423. At the same time, the power used to drive the deformation motor 423 to rotate will drive the electromagnetic plate 63, so that the magnetic force of the electromagnetic plate 63 can drive the electromagnetic block 66 to repel each other, allowing the positioning slide rod 64 to shrink inside the embedded storage groove 61, so that the retraction control box 411 is unlocked.

[0078] When the wheel leg deformation part 5 is deformed into the wheel body state, the drive motor 33 is started, and the drive motor 33 can be used to drive the drive motor to rotate. The rotation of the drive motor can drive the driven gear 412 to rotate. The rotation of the driven gear 412 can drive the rotating shaft 41 to rotate. The rotation of the rotating shaft 41 can use the fixed bar 54 to drive the wheel leg deformation part 5 to rotate, allowing the standing leg spring steel 51 to roll on the ground at high speed through the rubber tire 52, thereby realizing high-speed movement of the inspection body 1.

[0079] And by contracting the walking wheel feet 2, the inspection body 1 can slide at a low altitude at the bottom of the substation to complete the inspection of the bottom of the substation. When it is necessary to cross obstacles, it can be reversed to allow the wheel leg deformation part 5 to be deformed into a four-legged shape, and the two sections of the walking wheel feet 2 can be used to cooperate with each other to drive the inspection robot to complete the climbing and jumping.

[0080] It should be noted that when the wheel leg deformation member 5 is reversely deformed, the current is driven in the reverse direction, and the electromagnetic sheet 63 drives the electromagnetic block 66 to adsorb, and the positioning slide rod 64 is used to lock the rotating shaft 41.

[0081] It should be noted that before use, an inspection camera or inspection video camera or other equipment used for inspection can be installed inside the equipment installation slot 12 according to inspection needs.

[0082] It should be noted that the inspection body 1 is internally provided with a battery, which can drive all electric structures connected to the inspection body 1 .

[0083] It should be noted that in the present invention, the electromagnetic sheet 63 is electrically connected to the contact ring 35. When the contact ring 35 is energized, the electromagnetic sheet 63 is energized synchronously, starting the positioning slide 64 to be retracted or rotated out, completing the locking of the double-rod sleeve shaft 4.

[0084] In the present invention, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense.
