In this setting, the installation position of the second sliding mechanism is determined.

[0047] Embodiment 3:

[0048] The difference between the above embodiment and this embodiment is that: Figures 3 to 8 As shown, a tunnel unfavorable geological body advance geological prediction detection equipment, each inclined plate 304 is respectively movably penetrated through a side wall of a collection box 305, each inclined plate 304 is respectively movably installed with a movable rod 3041 at one end away from the rectangular installation tube 301, and each movable rod 3041 is movably installed with a sealing plate 3053 at the other end. In this arrangement, it is ensured that when the inclined plate 304 moves horizontally, the sealing plate 3053 can be driven to open with the assistance of the rectangular block 3054 and the sliding rod 3055 by the movable rod 3041, and because the collection box 305 is in a rotating and moving state, the soil and the like in the inner wall of the tunnel opening can be collected.

[0049] like Figures 3 to 8 As shown, in a specific embodiment, each sealing plate 3053 is slidably arranged on the inner wall of the collection box 305, and one side wall of each sealing plate 3053 is fixedly connected with four rectangular blocks 3054, and each rectangular block 3054 is symmetrical with each other, and each rectangular block 3054 is movably penetrated with a sliding rod 3055, and both ends of each sliding rod 3055 are fixedly connected to the inner wall of the collection box 305, and each side wall of each sealing plate 3053 is provided with a handle groove 3056. In this arrangement, it is ensured that the sealing plate 3053 can move horizontally.

[0050] The implementation principle of the advanced geological prediction detection device for tunnel unfavorable geological bodies in this embodiment is as follows:

[0051] First, the staff moves the installation unit 100 so that the drill bit 1021 provided at the installation unit 100 can fit with the tunnel wall. When the fit is achieved, the staff starts the servo motor 201. When the servo motor 201 is running, it can drive the threaded rod 2011 to rotate. When the threaded rod 2011 rotates, it can drive the threaded sleeve 212 to move horizontally with the assistance of the guide rod 2013.

[0052] At the same time, when the threaded rod 2011 rotates, it will be able to drive the circular fixing plate 202 to rotate. When the circular fixing plate 202 rotates, the circular fixing plate 202 will be able to drive the circular sleeve 2021 to rotate, so that the rectangular plug-in rod 2025 can be driven to rotate through the circular sleeve 2021, because the end of the rectangular plug-in rod 2025 away from the circular sleeve 2021 is fixedly connected to the circular mounting plate 203, and the circular mounting plate 203 is provided with a circular slide groove 2031, and the inner cavity of the circular slide groove 2031 is slidably installed with two mutually symmetrical guide sliders 2032, and the end of the guide slider 2032 away from the circular slide groove 2031 is fixedly connected to the connecting rod 2034, and the other end of the connecting rod 2034 is fixedly connected to the threaded sleeve 2012, so that the circular mounting plate 203 can be rotated and can also move horizontally;

[0053] Because a rectangular mounting tube 301 is fixedly mounted on one side wall of the circular mounting plate 203, and a drill bit 1021 is fixedly mounted on the rectangular mounting tube 301, a hole can be drilled in the tunnel wall by the drill bit 1021. Because a positioning rod 302 is provided in the inner cavity of the rectangular mounting tube 301, and the other end of the positioning rod 302 is fixedly connected to the inner wall of the circular sleeve 2021, when the circular mounting plate 203 moves, the rectangular mounting tube 301 can be driven to move. However, at this time, the positioning rod 302 is stationary. The fixing block 3021 is fixedly mounted on the positioning rod 302, so that the side wall of the fixing block 3021 can be pressed on the wedge block 303, so that the wedge block 303 can move outward, so that the wedge block 303 can drive the collecting box 305 to fit on the tunnel wall after the hole is opened, and at this time, the fixing block 3021 can be pressed on the inclined plate 304 set on the side wall of the wedge block 303, so that the inclined plate 304 can be pressed to move horizontally with the assistance of the second slide groove 3031 and the second slider 3032;

[0054] When the inclined plate 304 moves horizontally, the sealing plate 3053 can be driven to open with the assistance of the rectangular block 3054 and the sliding rod 3055 through the movable rod 3041. Since the collecting box 305 is in a rotating and moving state, the soil and the like in the inner wall of the tunnel opening can be collected.
