[0002] The surrounding rock collapse simulation device is an experimental device specifically designed to simulate the instability and collapse of surrounding rock in underground engineering projects (such as tunnels, underground chambers, etc.).
[0003] The surrounding rock collapse simulation device constructs a physical model space that approximates the surrounding rock environment of actual underground engineering, uses specific materials to simulate the surrounding rock, and is equipped with a device that can trigger the instability of the surrounding rock and a monitoring system, thereby reproducing the process of surrounding rock collapse under laboratory conditions.
[0004] In existing technologies, the image acquisition mechanism on rock collapse simulation devices is generally installed in a fixed position, which can only capture images of the rock collapse process from a specific angle. However, rock collapse is a complex three-dimensional spatial movement process.

In order to solve the above problems, a rock collapse simulation device is proposed. Utility Model Content

[0015] Three beneficial effects
[0016] Compared with the prior art, this utility model provides a rockfall simulation device, which has the following beneficial effects:
[0017] 1. This rockfall simulation device, through the cooperation of installed electric slide rails, sliding blocks, adjusting frames, motors, threaded rods, and adjusting blocks, enables the camera to be flexibly adjusted according to the simulated actual situation. The combination of electric slide rails and sliding blocks allows the camera to move flexibly in the longitudinal direction, while the cooperation of motors, threaded rods, and adjusting blocks allows the camera to be freely adjusted in the lateral direction. This achieves the goal of flexibly adjusting the camera according to the simulated actual situation, allowing the camera to be moved to a suitable shooting position. The images and video data captured from different angles and positions can more comprehensively and accurately reflect the process and characteristics of the rockfall.

The pressure and displacement sensors are installed at key locations on the inner wall of the simulation chamber. They can accurately sense the pressure changes and displacement of the surrounding rock during the simulated collapse process. The pressure sensor can measure the pressure on the surrounding rock at different locations. The collected data is transmitted to the display screen, where the pressure and displacement data change curves over time and the distribution at different locations within the simulation chamber can be seen intuitively.

[0029] In related technologies, the motor 302 is tightly connected to the rotating shaft via its output shaft. The rotating shaft and the cover plate 303 are fixed together by bolts, making the connection very strong. This ensures that when the rotating shaft rotates, it drives the cover plate 303 to rotate as well, realizing the opening and closing action of the simulated chamber 1. The electric slide rail 501 has a guide rail and slider structure inside. The sliding block 502 is nested on the guide rail, and the fit between the two is high, ensuring that the sliding block 502 can slide smoothly within the electric slide rail 501, thereby driving the second adjustment mechanism 6 connected to it to move horizontally. The output shaft of the motor 602 is connected to one end of the threaded rod 603 by a key. The key connection can effectively transmit the torque of the motor 602, so that the threaded rod 603 moves with the motor 602. The motor 602 rotates, and the threaded rod 603 is threadedly connected to the adjusting block 604. The adjusting block 604 has a threaded hole that matches the threaded rod 603. When the threaded rod 603 rotates, the adjusting bracket 601 restricts the rotational freedom of the adjusting block 604, so that the adjusting block 604 can only move along the axial direction of the threaded rod 603. This allows for vertical position adjustment of the camera 102, which is fixedly mounted at one end of the adjusting block 604. The positioning block 401 is fixed to the surface of the cover plate 303. The shape and size of the positioning block 401 are adapted to the positioning groove 402. When the cover plate 303 is closed, the positioning block 401 is inserted into the positioning groove 402, achieving accurate positioning and ensuring the cover plate 303 is closed. The rubber pad 403 is accurately positioned over the simulation chamber 1, ensuring its airtightness and relative stability of its internal structure. It is bonded to the surface of the cover plate 303. The rubber pad 403 possesses elasticity and flexibility; when the cover plate 303 is closed, it makes tight contact with the upper surface of the simulation chamber 1, further enhancing the sealing performance and preventing leakage of substances inside the chamber. It also acts as a buffer. One end of the support column 801 is fixed to the bottom of the simulation chamber 1, and the other end is fixedly connected to the base block 802. The base block 802 increases the contact area with the ground, improving the stability of the device. The pressure sensor 201 and displacement sensor 202 are fixedly installed in the simulation chamber 1. On the inner wall, pressure sensor 201 and displacement sensor 202 are electrically connected to display screen 203 via wires. The signal lines inside the sensors are led out and connected to the corresponding interfaces of display screen 203 via cables. This effectively ensures that the sensor signals are accurately transmitted to display screen 203, allowing staff to observe the pressure and displacement changes inside simulation chamber 1 in real time. Vibration motor 702 is fixedly installed at the bottom of simulation chamber 1. When vibration motor 702 is working, the vibration it generates is transmitted to vibration plate 701 through the output end, thereby causing the surrounding rock simulation material inside simulation chamber 1 to vibrate, simulating the vibration of surrounding rock in actual engineering, in order to study the collapse characteristics of surrounding rock under vibration.

When needed, the first adjustment mechanism 5 and the second adjustment mechanism 6 can be used to move the camera 102 flexibly in the longitudinal and lateral directions, allowing the camera 102 to be moved to a suitable shooting position. The images and video data captured from different angles and positions can more comprehensively and accurately reflect the process and characteristics of rockfall.
[0031] This application is described below with reference to the accompanying drawings and specific embodiments:
[0032] Combination Figure 1 - Figure 4 This application provides a rockfall simulation device, including a simulation chamber 1, tempered glass 101, and a camera 102.

[0035] Specifically, the motor 302 is tightly connected to the rotating shaft through the shaft at its output end. The rotating shaft and the cover plate 303 are fixed together by bolts, making the connection very strong. This ensures that when the rotating shaft rotates, it drives the cover plate 303 to rotate together, realizing the opening and closing action of the simulated chamber 1. The electric slide rail 501 has a guide rail and slider structure inside. The sliding block 502 is nested on the guide rail. The fit between the two is high, ensuring that the sliding block 502 can slide smoothly in the electric slide rail 501, thereby driving the second adjustment mechanism 6 connected to it to move in the horizontal direction.

A plurality of rubber pads 403 are adhered to the surface of the cover plate 303.
[0037] The bottom of the simulation chamber 1 is provided with a support component 8, which includes a support column 801 fixedly connected to the bottom of the simulation chamber 1. One end of the support column 801 is fixedly connected to a bottom block 802, and a shock-absorbing pad 803 is glued to the bottom of the bottom block 802.
[0038] Specifically, the positioning block 401 is fixed to the surface of the cover plate 303. The shape and size of the positioning block 401 are adapted to the positioning groove 402. When the cover plate 303 is closed, the positioning block 401 is inserted into the positioning groove 402, which plays an accurate positioning role, ensuring that the cover plate 303 can accurately cover the simulation chamber 1, ensuring the airtightness of the simulation chamber 1 and the relative stability of the internal structure. The rubber pad 403 is fixed to the surface of the cover plate 303 by adhesive. The rubber pad 403 has a certain elasticity and flexibility. When the cover plate 303 is closed, the rubber pad 403 will be in close contact with the upper surface of the simulation chamber 1, further enhancing the sealing performance and preventing the leakage of substances inside the simulation chamber 1. At the same time, it can also play a buffering role. One end of the support column 801 is fixed to the bottom of the simulation chamber 1, and the other end of the support column 801 is fixedly connected to the bottom block 802. The bottom block 802 can increase the contact area with the ground and improve the stability of the device.
[0039] In some embodiments, a monitoring mechanism 2 is provided inside the simulation chamber 1.

[0040] The simulation chamber 1 is equipped with a vibration mechanism 7. The vibration mechanism 7 includes a vibration motor 702 fixedly installed at the bottom of the simulation chamber 1. The output end of the vibration motor 702 extends into the simulation chamber 1 and is connected to a vibration plate 701.
[0041] Specifically, pressure sensor 201 and displacement sensor 202 are fixedly installed on the inner wall of simulation chamber 1.
