[0039] The basic principle of this utility model:
[0040] like Figure 1 As shown, when the device receives the detection command, it pulls up the steel wire rope 15 to release the line, thereby causing the disc 10 to move downward along the positioning steel wire rope 14 through the steel wire rope hole 101 to perform detection. At this time, the extension plates 20 are all retracted into the side groove 11 of the disc 10. The fixed ground penetrating radar 102 and the mobile ground penetrating radar 33 work together to perform circular line detection. At the same time, the three-dimensional laser scanner 41, CCD camera 43 and light source 44 work synchronously to perform three-dimensional scanning and image acquisition detection.
[0041] When an unidentified defect is detected, the electric pusher 24 drives the lever 25 to extend, which in turn causes the extension plate 20 to extend along the side groove 11 and the side slide groove 111 via the inclined seat 21. During the extension, the extension plate 20 also extends along with connecting rod 26, connecting rod 27, and the arc-shaped plate 30. The gear 262 of connecting rod 26 rotates via the rack 121, and connecting rod 26, through connecting rod 27, causes the arc-shaped plate 30 to move out of the slide hole 23 via the sliding plate 34, until the gear 262 disengages from the rack 121, achieving the desired result. Figure 2 The working status is shown;
[0042] Then the electric pusher 24 continues to drive the extension plate 20 to extend, and the extension plate 20, together with the connecting rod 1 26, the connecting rod 27, and the arc plate 30, is extended until it is completely extended, and then the mobile ground penetrating radar 33 performs close-range detection.
[0043] After the proximity test is completed, the device will respond as follows: Figure 1 As shown in the diagram, the steel wire rope 15 is then pulled up to continue releasing the line, causing the disc 10 to probe downwards.
[0044] When the bottom of the well is reached, the reverse program is initiated, the steel wire rope 15 is pulled up to start winding, causing the disc 10 to return upwards. When the top of the well is reached, the movement stops.
