Therefore, the push plate 4025 can push the handle of the valve 1015 to rotate, so that it can close the valve 1015 and stop the water supply.

[0049] The implementation principle of a tunnel water inrush simulation test device of the present invention is as follows:

[0050] First, the staff installs the tunnel wall simulation board 1012 on one side wall of the tunnel model body 1011 (its specific installation is the existing technology). When the installation is completed, the staff controls the hydraulic cylinder 201 to operate through the controller, so that the hydraulic cylinder 201 can push the circular sealing column 2011 to move horizontally. When the circular sealing column 2011 moves horizontally, it can drive the movable sealing board 2012 to move horizontally in the inner cavity of the water tank 102, so that the movable sealing board 2012 can squeeze the water in the inner cavity of the water tank 102, so that the water pressure in the water outlet protection frame 1013 increases, thereby increasing the pressure on the tunnel wall simulation board 1012 (so that the tunnel water inrush experiment can be simulated);

[0051] When water seeps from the tunnel wall simulation plate 1012, the water can enter the inner cavity of the tunnel model body 1011, so that the water can flow into the sponge plate 3011, because the sponge plate 3011 is placed on the lightly floating placement plate 301, and the gravity of the sponge plate 3011 gradually increases after absorbing water, so that the gravity will be greater than the elastic force of the first return spring 3025 and the second return spring 3027, so that the sponge plate 3011 can press the lightly floating placement plate 301 to move vertically downward with the assistance of the first slide groove 3012 and the first slider 3013 in the first sliding mechanism;

[0052] When the light floating plate 301 moves vertically downward, it will be able to squeeze the inclined impact plate 3024 and the inclined sound plate 3026, and will be able to move horizontally with the assistance of the second slide groove 3021 and the second slider 3022 in the second sliding mechanism and the moving plate 3023, so that the inclined impact plate 3024 and the inclined sound plate 3026 can be separated, until the light floating plate 301 is located below the inclined impact plate 3024 and the inclined sound plate 3026, at this time, the inclined impact plate 3024 and the inclined sound plate 3026 can make the moving plate 3023 move horizontally with the assistance of the second sliding mechanism under the elastic force of the first return spring 3025, so that the inclined impact plate 3024 and the inclined sound plate 3026 can collide with each other, and the first return spring 3025 is reciprocating, so it can collide back and forth during the period, thereby generating a sound, and the sound generated at this time can be transmitted from the phoenix hole 303, so that the staff can be reminded that the tunnel wall simulation plate 1012 has water seepage;

[0053] When the floating plate 301 moves to a certain position, the floating plate 301 can drive the wedge block 304 to move to a certain position, because the wedge block 304 can squeeze the sliding plate 3041 to move horizontally with the assistance of the slide rail 3042. When the sliding plate 3041 moves, the sliding plate 3041 can push the fixed plate 4014 to drive the rotating disk 4012 to rotate with the assistance of the rotating rod 401 and the bearing 4011.

[0054] When the rotating disk 4012 rotates, the rotating disk 4012 will be able to drive the movable slider 4021 to move horizontally with the assistance of the arc-shaped slide groove 402 and the sliding rod 4022. When the movable slider 4021 moves horizontally, it will be able to drive the connecting rod 4023 to move. When the connecting rod 4023 moves, it will be able to drive the Z-shaped plate 4024 to move horizontally. When the Z-shaped plate 4024 moves horizontally, it will be able to drive the push plate 4025 to move horizontally. Therefore, the push plate 4025 can push the handle of the valve 1015 to rotate, so that it can close the valve 1015 and stop the water supply.
