[0023] The obstacle clearing mechanism 2 includes a bidirectional lead screw 29 rotatably connected inside the mounting frame 1. A movable seat 28 is symmetrically screwed onto the surface of the bidirectional lead screw 29. Connecting members 27 are hinged onto the surface of the movable seat 28. The other ends of the two sets of connecting members 27 are hinged to hinge seats 21. Mounting seats 22 are symmetrically arranged on the front side of the mounting frame 1. Pushing plates 23 are hinged onto the surface of each mounting seat 22. An extension plate 24 is slidably connected inside the pushing plate 23, and one adjacent side of the extension plate 24 is hinged to the hinge seat 21. A first motor 210 is fixedly connected to the side of the mounting frame 1 closest to the bidirectional lead screw 29, and the output end of the first motor 210 is connected to the bidirectional lead screw 29 via a reducer. The mounting frame 1 is installed in front of the fire-fighting robot. The fire-fighting robot operates... When obstacle removal is required during the process, the first motor 210 is started to drive the bidirectional lead screw 29 to rotate, which in turn drives the movable seat 28 screwed to the surface of the bidirectional lead screw 29 to move closer together. The connecting piece 27 pushes the hinge seat 21 to move forward, causing the extension plate 24 to slide out from inside the push plate 23, so that the push plate 23 and the extension plate 24 form a V-shaped guide plate. In conjunction with the movement of the fire-fighting robot, the obstacles in front of the mounting frame 1 are automatically moved to both sides to complete the obstacle removal operation. When obstacle removal is not required, the first motor 210 drives the movable seat 28 to move to both sides, and then pulls the extension plate 24 to be stored inside the push plate 23, making the push plate 23 parallel to the mounting frame 1, reducing the area occupied by the device and facilitating the movement of the fire-fighting robot.

[0026] Working principle and process: when the fire-fighting robot works, the mounting frame 1 is installed in front of the fire-fighting robot, when it is necessary to clean the obstacle, the first motor 210 is started to drive the bidirectional screw rod 29 to rotate, and the moving seat 28 screwed on the surface of the bidirectional screw rod 29 is brought close to each other, the hinged seat 21 is pushed by the connecting piece 27 to move to the front side, the extension plate 24 is slid out from the inside of the push barrier plate 23, the push barrier plate 23 and the extension plate 24 form a V-shaped guide plate, the obstacles in front of the mounting frame 1 are automatically moved to both sides, the cleaning work is completed in cooperation with the movement of the fire-fighting robot, the second motor 31 drives the cleaning brush 32 to rotate, and then the cleaning brush 32 rotates at high speed to clean small obstacles, and the push barrier plate 23 can clean various types and sizes of obstacles, and the obstacle cleaning ability of the fire-fighting robot in a complex fire scene is improved, the impact force generated by the collision can be absorbed through the buffer dampers 25 and the buffer springs 270, the fire-fighting robot is protected, and the damage of the fire-fighting robot caused by directly impacting the obstacle is reduced.
