[0002] The inspection robot is a new type of robot that can move back and forth in a designated working area and detect the working area. It replaces the previous manual inspection method, which not only saves labor but also improves the accuracy of detection. Inspection robots are mainly divided into two types: tracked and trackless. Among them, trackless inspection robots have a higher degree of freedom in inspection. Trackless inspection robots are mostly used for inspection in the corridors of the dam.

[0003] However, in the prior art, the water in the corridor of the dam needs to be drained before inspection. After the water is drained, stones or solid waste may remain in the corridor. When the trackless inspection robot is inspecting, these obstacles may prevent the robot from continuing to move, requiring staff to enter the corridor in time for cleaning, which adds additional obstacle clearing burden to the staff. To address the above problems, a trackless corridor inspection robot is proposed. Summary of the invention

[0004] The purpose of the present invention is to solve the problem in the prior art that before inspection, the water inside the corridor of the dam needs to be discharged. After the water is discharged, stones or solid waste may remain in the corridor. When the trackless inspection robot is inspecting, these obstacles may block the robot from continuing to move, requiring staff to enter the corridor in time for cleaning, which adds additional obstacle clearing burden to the staff. A trackless corridor inspection robot is proposed.

[0006] Preferably, a positive baffle is provided at one end of the bidirectional rack, and four mounting sleeves are fixedly connected to one end of the positive baffle. The inner walls of two mounting sleeves are rotatably connected to fixing rods, and the outer surface of the fixing rod is provided with a clockwork spring.

[0007] Preferably, a connecting plate is provided at one end of the forward baffle, and two grooves are provided at one end of the connecting plate, and the two ends of the two fixing rods are respectively fixedly mounted on the inner walls of the two grooves.

DETAILED DESCRIPTION

[0020] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1

[0023] like Figure 1-4 As shown, the present invention provides a trackless corridor inspection robot, including a robot body 1 and a detection camera 2. A mounting groove 101 is opened at one end of the robot body 1, and an obstacle clearing mechanism 3 is arranged inside the mounting groove 101. The obstacle clearing mechanism 3 includes a cylinder 301, and a bidirectional rack 302 is fixedly installed at the telescopic end of the cylinder 301. Two gears 303 are meshed at both ends of the bidirectional rack 302. A No. 1 rotating rod 304 is fixedly installed at the top of the gear 303, and an arc baffle 305 is fixedly installed at one end of the No. 1 rotating rod 304. One end of the arc baffle 305 is fixedly connected to a side baffle 306, and a No. 2 rotating rod 307 is fixedly installed at the other end of the arc baffle 305. One end of the No. 2 rotating rod 307 is rotatably connected to one end of the robot body 1, the bottom end of the cylinder 301 is fixedly installed to the bottom end of the inner wall of the mounting groove 101, the gear 303 is rotatably connected to the bottom end of the inner wall of the mounting groove 101, and the bottom end of the detection camera 2 is movably installed at the top of the robot body 1.

[0024] The following is a detailed description of the specific settings and functions of this embodiment. When an obstacle appears in front of the robot body 1, the detection camera 2 will detect it in time. The staff can connect the cylinder 301 with the detection camera 2 through electrical signals. When the detection camera 2 detects an obstacle, the detection camera 2 will control the cylinder 301 to work. After the cylinder 301 works, it pushes the two-way rack 302 to move and rotates the two gears 303. When the two gears 303 rotate, they will drive the arc baffle 305 to push the obstacle to both sides through the two No. 1 rotating rods 304. The side baffle 306 can clamp the obstacle so that the obstacle can be pushed away better. The No. 2 rotating rod 307 plays a supporting role to prevent the obstacle from causing the arc baffle 305 to be dislocated. After the obstacle is pushed to both sides of the robot body 1, the telescopic end of the cylinder 301 is retracted to reset the two arc baffles 305.

[0025] Embodiment 2

[0026] like Figure 1 and Figure 2 As shown, a forward baffle 4 is provided at one end of the bidirectional rack 302, and four mounting sleeves 401 are fixedly connected at one end of the forward baffle 4. The inner walls of the two mounting sleeves 401 are rotatably connected with fixed rods 402, and the outer surfaces of the fixed rods 402 are provided with spring springs 7. A connecting plate 5 is provided at one end of the forward baffle 4, and two grooves 501 are provided at one end of the connecting plate 5. The two ends of the two fixing rods 402 are respectively fixedly installed on the inner walls of the two grooves 501, and the other end of the connecting plate 5 is fixedly connected to two connecting rods 6, one end of the connecting rod 6 is fixedly installed on one end of the bidirectional rack 302, one end of the spring spring 7 is fixedly connected to the outer surface of the fixing rod 402, and the other end of the spring spring 7 is fixedly connected to one end of one of the mounting sleeves 401.

[0027] The effect achieved by the entire embodiment is that after the bidirectional rack 302 is pushed, the forward baffle 4 is pushed out through the connecting rod 6 and the connecting plate 5. The outer side of the forward baffle 4 is also provided with a certain curvature. After the forward baffle 4 contacts the obstacle on the front of the robot body 1, it will rotate around the axis of the fixed rod 402 due to its curved surface, so that the forward baffle 4 will push the obstacle on the front away and offset it, allowing the obstacle to move to the side baffle 306. At the same time, the clockwork spring 7 will twist and generate elastic force after the installation sleeve 401 is rotated. After the obstacle is separated from the forward baffle 4, the elastic force of the clockwork spring 7 will reset the forward baffle 4.

[0028] The use method and working principle of this device: when an obstacle appears in front of the robot body 1, the detection camera 2 will detect it in time, and the staff can connect the cylinder 301 with the detection camera 2 through electrical signals. When the detection camera 2 detects an obstacle, the detection camera 2 will control the cylinder 301 to work. After the cylinder 301 works, it pushes the two-way rack 302 to move and rotates the two gears 303. When the two gears 303 rotate, they will drive the arc baffle 305 to push the obstacle to both sides through the two No. 1 rotating rods 304. The side baffle 306 can clamp the obstacle so that the obstacle can be pushed away better. The No. 2 rotating rod 307 plays a supporting role to prevent the obstacle from causing the arc baffle 305 to be misplaced. After the obstacle is pushed to both sides of the robot body 1, the cylinder 301 The telescopic end is recovered to reset the two arc-shaped baffles 305; a positive baffle 4 is provided at one end of the bidirectional rack 302, and one end of the positive baffle 4 is fixedly connected with four mounting sleeves 401, the inner walls of the two mounting sleeves 401 are rotatably connected with fixed rods 402, and the outer surface of the fixed rods 402 is provided with a clockwork spring 7, and one end of the positive baffle 4 is provided with a connecting plate 5, and one end of the connecting plate 5 is provided with two grooves 501, and the two ends of the two fixing rods 402 are respectively fixedly installed on the inner walls of the two grooves 501, and the other end of the connecting plate 5 is fixedly connected with two connecting rods 6, one end of the connecting rod 6 is fixedly installed on one end of the bidirectional rack 302, one end of the clockwork spring 7 is fixedly connected to the outer surface of the fixing rod 402, and the other end of the clockwork spring 7 is fixedly connected to one end of one of the mounting sleeves 401.
