The following embodiments are used to illustrate the present invention.

[0038] Example 1:

A connecting pipe 1014 is connected to a side wall away from the tunnel model body 1011, and a valve 1015 is provided on the connecting pipe 1014. One end of the connecting pipe 1014 away from the water outlet protection frame 1013 is connected to the water tank 102. A protective sleeve 103 is installed on the side wall of the water tank 102 away from the connecting pipe 1014. A support frame 1031 is fixedly installed at the bottom of the protective sleeve 103. The other end of the support frame 1031 is fixedly connected to the top of the workbench 101. A movable slot is opened in the workbench 101. 1016, rectangular groove 1017, placement slot 1018 and installation slot 1019, which are interconnected, and the two opposite walls of the workbench 101 are provided with phoenix holes 303; the alarm unit 300 includes a plurality of inclined impact plates 3024 and inclined sound plates 3026, each inclined impact plate 3024 and inclined sound plate 3026 are symmetrical to each other; the locking unit 400 includes a push plate 4025, the bottom of the push plate 4025 is fixedly mounted with a Z-shaped plate 4024, and the bottom of the Z-shaped plate 4024 is provided with A rotating disk 4012 has a rotating rod 401 fixedly passing through the middle of the rotating disk 4012, a bearing 4011 is provided at the bottom of the rotating rod 401, the bearing 4011 is provided in the inner cavity of the workbench 101, a torsion spring 4013 is provided on the side wall opposite to the bearing 4011 and the rotating disk 4012, the push plate 4025 and the valve 1015 cooperate with each other, and a fixed plate 4014 is fixedly installed on the side wall of the rotating disk 4012; the transmission unit 200 includes a driving assembly, which is used to drive the water pressure in the water tank 102 to change.When the sponge plate 3011 is soaked in water to a certain extent, the sponge plate 3011 will press the floating plate 301 to move horizontally downward with the assistance of the first sliding mechanism, thereby squeezing the inclined impact plate 3024 and the inclined sound plate 3026 to move to both sides, until the 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 collide with each other with the assistance of the first return spring 3025. At the same time, because the first return spring 3025 has reciprocating properties, it can The inclined impact plate 3024 and the inclined sound plate 3026 collide back and forth, making a sound, which can be transmitted from the phoenix hole 303 to remind the staff. At the same time, when the frivolous placement plate 301 moves vertically downward, it can drive the wedge block 304 to squeeze the sliding plate 3041 to drive the rotating disk 4012 to rotate, so that the arc-shaped groove 402 and the moving slider 4021 on the rotating disk 4012 can drive the Z-shaped plate 4024 and the push plate 4025 to move horizontally, so that the valve 1015 handle can be pushed by the push plate 4025 to close.

[0040] like Figure 3 As shown, in a specific embodiment, the drive assembly includes a hydraulic cylinder 201, which is installed in the inner cavity of the protective sleeve 103. A circular sealing column 2011 is fixedly installed at the output end of the hydraulic cylinder 201. The other end of the circular sealing column 2011 is located in the inner cavity of the water tank 102, and a movable sealing plate 2012 is fixedly installed at the end. The movable sealing plate 2012 slides on the inner wall of the water tank 102. A water inlet 1021 is opened above the water tank 102. In this configuration, the installation position and components of the drive assembly are determined.

[0041] like Figures 4 to 6 As shown, a first sliding mechanism is further provided on opposite sides of the inner cavity of the movable slot 1016. The first sliding mechanism includes two first chute grooves 3012, which are symmetrical with each other. A first slider 3013 is slidably mounted in the inner cavity of each of the two first chute grooves 3012. The two first sliders 3013 are symmetrical with each other. A buoyant placement plate 301 is fixedly connected to the opposite side wall of the two first sliders 3013, and a sponge plate 3011 is placed in the inner cavity of the buoyant placement plate 301. In this configuration, the installation position and components of the first sliding mechanism are determined.

[0042] Example 2:

[0043] The difference between Example 1 and this example is that: Figures 1 to 3As shown, a tunnel water inrush simulation test device has multiple equally spaced rectangular slots 302 formed on opposite sides of the movable slot 1016. Each rectangular slot 302 is symmetrical to each other, and each rectangular slot 302 has a second sliding mechanism disposed within its cavity. In this configuration, the positions of the rectangular slots 302 are determined.

[0044] like Figures 4 to 7 As shown, in a specific embodiment, the second sliding mechanism includes two second sliding grooves 3021, each of which is provided on opposite side walls of the rectangular slot 302. The two second sliding grooves 3021 are symmetrical to each other, and a second slider 3022 is slidably mounted in each of the two second sliding grooves 3021. The two second sliders 3022 are symmetrical to each other, and a movable plate 3023 is fixedly connected to the opposite side walls of the two second sliders 3022. In this configuration, the installation position and components of the second sliding mechanism are determined.

[0045] like Figures 4 to 7 As shown, each movable plate 3023 has a tilted impact plate 3024 and a tilted sound plate 3026 fixedly connected to opposite side walls thereof. Opposite ends of each movable plate 3023 are fixedly connected to first return springs 3025, and opposite ends of the two first return springs 3025 are fixedly connected to the inner wall of the rectangular notch 302. This arrangement ensures that when the floating placement plate 301 is positioned below the tilted impact plate 3024 and the tilted sound plate 3026, the tilted impact plate 3024 and the tilted sound plate 3026 can, under the elastic force of the first return springs 3025, cause the movable plate 3023 to move horizontally with the assistance of the second sliding mechanism, thereby allowing the tilted impact plate 3024 and the tilted sound plate 3026 to collide with each other. The reciprocating nature of the first return springs 3025 allows for a back-and-forth collision, thereby producing a sound.

[0046] like Figures 4 to 7 As shown, two symmetrical second return springs 3027 are fixedly mounted on the bottom of the floating plate 301, and the other ends of the second return springs 3027 are fixedly connected to the bottom of the inner cavity of the movable slot 1016. A wedge block 304 is also fixedly mounted on the bottom of the floating plate 301, and the wedge block 304 and the rectangular slot 1017 fit together. This arrangement ensures that the floating plate 301 can be reset.

[0047] Example 3:

[0048] The difference between Example 2 and this example is that: Figures 2 to 3 and Figure 8 branch Figure 9As shown, a tunnel water inrush simulation test device is provided. A slide rail 3042 is provided at the bottom of the inner cavity of the placement slot 1018. A sliding plate 3041 is slidably mounted above the slide rail 3042. The inclined surfaces of the sliding plate 3041 and the wedge block 304 engage with each other, and the end of the sliding plate 3041 away from the wedge block 304 engages with the fixed plate 4014. This arrangement ensures that the sliding plate 3041 can move horizontally. A third sliding mechanism is provided above the rotating disk 4012. The third sliding mechanism includes an arcuate chute 402. A movable slider 4021 is slidably mounted within the inner cavity of the arcuate chute 402. Sliding rods 4022 are slidably mounted on opposite side walls of the movable slider 4021. The two sliding rods 4022 are symmetrical and fixedly connected at their ends to opposite side walls of the inner cavity of the workbench 101. A connecting rod 4023 is fixedly mounted above the movable slider 4021, and a Z-shaped plate 4024 is fixedly connected above the connecting rod 4023. In this setting, it is ensured that 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, and 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, so that 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 installed the tunnel wall simulation plate 1012 on one side wall of the tunnel model body 1011 (its specific installation is based on the existing technology). When the installation is completed, the staff controlled the hydraulic cylinder 201 through the controller to operate, 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 plate 2012 to move horizontally in the inner cavity of the water tank 102, so that the movable sealing plate 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 plate 1012 (thus simulating the tunnel water inrush experiment);

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

[0052] When the light placing 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 placing 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 be able to move horizontally with the assistance of the second sliding mechanism under the elastic force of the first return spring 3025, so that the moving plate 3023 can move horizontally with the assistance of the second sliding mechanism, so that the inclined impact plate 3024 and the inclined sound plate 3026 can collide with each other. The first return spring 3025 has a reciprocating nature, so it can collide back and forth, thereby generating a sound. The sound generated at this time can be transmitted from the phoenix hole 303, so as to remind the staff 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.
