[0040] In order to make the purpose and advantages of the present invention more clearly understood, the present invention is described in detail below with reference to the following examples. It should be understood that the following text is only used to describe one or more specific embodiments of the present invention and does not strictly limit the scope of protection of the present invention.

[0041] like Figures 1-6 As shown, a similar simulation experimental device for multi-source disasters in mining areas includes a base frame 1, and an earthquake simulation mechanism, a mining disturbance simulation mechanism, and a water inrush simulation mechanism are assembled on the upper side of the base frame 1;

[0042] The earthquake simulation mechanism includes a separate bottom plate and a side pressure mechanism;

[0043] Among them, the separable bottom plate includes two movable bottom plates 2 that can be moved horizontally on the base frame 1. A splicing plate 3 is fixedly connected between the two movable bottom plates 2. A plurality of dividing lines are set on the splicing plate 3. The splicing plate 3 can be divided into two separation plates along any dividing line. At this time, the mining area model is placed on the splicing plate 3, and then the movable bottom plate 2 is slid to drive the two separation plates to move away from each other, thereby applying relative pulling force to the mining area model.

[0044] Here, both ends of the base frame 1 are fixedly connected with a first hydraulic rod 4, and the piston rods of the two first hydraulic rods 4 are fixedly connected to the two movable bottom plates 2 respectively. By starting the first hydraulic rod 4, the movable bottom plates 2 can be driven to slide, thereby controlling the change in the distance between the two movable bottom plates 2.

[0045] Specifically, such as Figure 1 and Figure 4 As shown, the splicing plate 3 includes a plurality of rectangular plates in a rectangular array, and the two rows of rectangular plates on both sides are fixedly connected to the two movable bottom plates 2 respectively, and the two adjacent rectangular plates are fixedly connected by an electric connection structure. At this time, several electric connection structures are numbered, and the electric connection structures with corresponding numbers are unlocked according to needs, so that the plurality of rectangular plates can be divided into two parts.

[0046] At the same time, in order to make the boundary lines of the two separation plates after the spliced plate 3 is separated more complex, so that the shape of the separation plate can be better controlled according to user needs, the rectangular plate includes four triangular plates 17, and the triangular plates 17 of two adjacent rectangular plates are fixedly connected by an electric connection structure, and the two adjacent triangular plates 17 in the same rectangular plate are fixedly connected by an electric connection structure.

[0047] Specifically, the cross-section of the triangular plate 17 is an isosceles right triangle, so that the four triangular plates 17 are equally divided.

[0048] like Figure 4-Figure 6 As shown, the electric connection structure includes a primary locking groove 18 respectively opened on the two triangular plates 17, and the interior of the primary mounting groove 19 is fixedly connected with an electric telescopic card block, which can be clamped in the interior of the primary locking groove 18 to complete the connection between the two adjacent triangular plates 17. When the electric telescopic card block is retracted from the interior of the primary locking groove 18, the separation of the two triangular plates 17 can be completed.

[0049] The electric telescopic card block includes a primary electromagnet 20, a primary return spring 21 and a primary lock plate 22. The primary electromagnet 20 is fixedly connected to the inside of the primary mounting slot 19, and the primary lock plate 22 is slidably connected to the inside of the primary mounting slot 19, and the primary lock plate 22 can extend out of the primary mounting slot 19 and be clamped in the inside of the primary locking slot 18. The primary return spring 21 is fixedly connected between the primary lock plate 22 and the primary electromagnet 20. When the primary electromagnet 20 is powered off, the primary lock plate 22 is pushed out by the primary return spring 21, so that the primary lock plate 22 can be automatically locked in the primary locking slot 18. When the primary electromagnet 20 is connected to an external power supply, the magnetic force can be released. The primary lock plate 22 has a magnetic material such as iron, so that the magnetic force released by the primary electromagnet 20 can pull the primary lock plate 22, and the primary lock plate 22 is retracted into the inside of the primary mounting slot 19. Its structure is relatively simple and the operation is relatively convenient.

[0050] The first locking plate 22 is provided with a second mounting groove 25 on both sides of the first locking groove 18, and a second electromagnet 26 is fixedly connected to the interior of the second mounting groove 25. A second return spring 27 is fixedly connected to one side of the second electromagnet 26. The end of the second return spring 27 is fixedly connected to a second locking rod 23 that slides along the axial direction of the second mounting groove 25. The second locking rod 23 can be clamped in the interior of the second locking hole 24. The second locking rod 23 is also provided with a magnetic material such as iron. When the second electromagnet 26 is energized by an external power supply, a pulling force can be applied to the second locking rod 23, so that the second locking hole 24 is retracted into the second mounting groove 25. At this time, the first locking plate 22 can be driven in and out of the first locking groove 18. When the second electromagnet 26 is powered off, the second locking rod 23 can be automatically pushed out by the second electromagnet 26 and enter the interior of the second locking hole 24.

[0051] Specifically, the end of the secondary locking rod 23 away from the secondary return spring 27 is a hemispherical structure. By improving the shape of the end of the secondary locking rod 23, the secondary locking rod 23 can be more easily inserted into the secondary lock hole 24.

[0052] At the same time, the middle position of the base frame 1 is fixedly connected to a collecting hopper 8 located on the lower side of the splicing plate 3, and the lower side of the collecting hopper 8 is fixedly connected to a discharge pipe 9. During the experiment, the particles falling off the mining area model will fall into the collecting hopper 8 and then be discharged in a centralized manner through the discharge pipe 9.

[0053] Among them, the side pressure mechanism is used to apply side pressure to the mining area model. The side pressure mechanism includes two groups of second hydraulic rods 5. The output end of each group of second hydraulic rods 5 is fixedly connected to a side pressure plate 6. By starting the two groups to drive the side pressure plates 6 to move, side pressure can be applied to the mining area model.

[0054] like Figure 1-Figure 2 As shown, the mining disturbance simulation mechanism is used to apply a vibration force to the joint plate 3 to simulate mining disturbance;

[0055] Specifically, the mining disturbance simulation mechanism includes an electromagnetic vibrator 7 fixedly connected to the lower side of the base frame 1. By starting the electromagnetic vibrator 7, a vibration force can be applied to the base frame 1, and then transmitted to the splicing plate 3 through the movable bottom plate 2, and then transmitted to the mining area model on the splicing plate 3.

[0056] At the same time, the electromagnetic vibrator 7 can also be directly fixedly connected to the upper side of the movable base plate 2, thereby reducing the transmission loss of the vibration force.

[0057] Among them, such as Figure 1-Figure 3As shown, the water inrush simulation mechanism is used to add a water flow simulating water inrush to the mining area model. The water inrush simulation mechanism includes a water storage bag 11. The water storage bag 11 is connected to a water injection pipe 10. The water injection equipment of the water pump is connected to the water injection pipe 10 to flush water and pressurize the inside of the water storage bag 11. The outer side of the water storage bag 11 is fixedly connected to an electromagnetic water outlet valve 12. When in use, the water storage bag 11 is placed on the upper side, lower side or middle position of the mining area model, and then the electromagnetic water outlet valve 12 is opened. Water is discharged through the electromagnetic water outlet valve 12 to simulate the water inrush phenomenon.

[0058] Specifically, the water storage bag 11 includes a flexible bag 13, and a flexible spacer 14 is fixedly connected to the interior of the flexible bag 13. The flexible spacer 14 divides the interior of the flexible bag 13 into a pressurized area 15 and a water storage area 16. The pressurized area 15 is connected to the water injection pipe 10, and the water storage area 16 is connected to the electromagnetic water outlet valve 12. The material of the flexible bag 13 and the flexible spacer 14 can both be rubber. When the water injection pipe 10 injects water into the pressurized area 15, the flexible spacer 14 can be pushed to pressurize the water inside the water storage area 16, thereby ensuring the water pressure inside the water storage area 16 while preventing subsequently added water from entering the water storage area 16.

[0059] The flexible pouch 13 and the flexible spacer 14 can both be made of rubber or leather.

[0060] A method for using a similar simulation experimental device for multi-source disasters in mining areas comprises the following steps:

[0061] Step 1: Place the mining area model on the upper side of the splicing plate 3;

[0062] Step 2: Select at least one of a water inrush simulation experiment, an earthquake simulation experiment, or a mining disturbance simulation experiment;

[0063] If a water inrush test is conducted, the water storage bag 11 is pressurized through the water injection pipe 10. After the pressurization is completed, the electromagnetic water outlet valve 12 is opened to allow the water in the water storage bag 11 to enter the mining area model;

[0064] If a mining disturbance simulation experiment is conducted, the electromagnetic vibrator 7 is turned on to apply a vibration force to the mining area model through the electromagnetic vibrator 7;

[0065] If an earthquake simulation experiment is conducted, the movable bottom plate 2 is moved or a side pressure mechanism is used to apply side pressure to the mining area model;

[0066] When the movable bottom plate 2 slides, it drives the two separation plates to move away from each other, exerting relative pulling force on the mining area model;

[0067] Step 3: After the experiment is completed, the mining area model is tested and recorded.

[0068] The foregoing is merely a preferred embodiment of the present invention. It should be noted that those skilled in the art may make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also within the scope of protection of the present invention.
