[0019] Reference Figure 1-6 The present invention provides a visual inspection device for a narrow space, comprising: The main body unit 100 includes a hollow beam plate main body 101, and a plurality of openings 102 are formed on the hollow beam plate main body 101; The operating unit 200 includes a plurality of support rods 201, on which a directional control valve 203 is provided, and a transverse plate 204 is fixedly connected to the end of the directional control valve 203. Suspension cables 205 are symmetrically and slidably arranged between the two transverse plates 204, and a high-definition camera device 206 is slidably arranged on the suspension cable 205. A moving component 207 is provided between the high-definition camera device 206 and the support rods 201, and a tightening component 210 for tightening the suspension cable 205 is provided at the bottom of the base plate 202.

[0020] Among them, the moving component 207 includes two mounting plates 207a, the mounting plates 207a are fixedly connected to the support rod 201, and the mounting plates 207a are rotatably connected to the guide wheels 207b. The left and right sides of the high-definition camera device 206 are symmetrically fixedly connected with traction cables 207c. The traction cables 207c cooperate with the guide wheels 207b.

The high-definition camera device 206 synchronizes the collected images to the display device 209 in real time, and the staff can observe the interior thereof through the display device 209 .

[0027] During use, first, openings 102 are opened at both ends of the section to be inspected, and then the suspension cable 205 and the moving component 207 are passed through the opening 102 and extended to the outside, and the suspension cable 205 is passed through the cross plate 204, and then the support rod 201 is inserted into the hollow beam body 101, and then the suspension cable 205 is wound and tightened by rotating the winding roller 210c, and then the moving component 207 is pulled to drive the high-definition camera device 206 to move left and right to detect the inside. At the same time, the adjusting valve 203 can drive the cross plate 204 to swing, so that the high-definition camera device 206 can adjust the angle. The operation is simple and convenient, which is convenient for the staff to detect its internal structure.
