Description

Technical Field

[0001] The utility model relates to the technical field of geological research, in particular to a rock and soil stratum simulation device used for rock and soil seismic wave observation experiments. Background Art

[0002] Earthquake disasters are currently the most destructive natural disasters. In order to ensure that the losses are minimized when an earthquake disaster occurs, people need to simulate earthquake disasters on a small scale and come up with corresponding countermeasures to avoid the problem of heavy losses caused by failure to respond in a timely and effective manner when an earthquake disaster occurs. Therefore, in the prior art, an earthquake simulator is set up to simulate the vibration of an existing earthquake, so that people can understand some phenomena that will occur when an earthquake occurs. Then, based on these phenomena, corresponding countermeasures can be effectively studied, so that when an actual earthquake occurs, the losses caused by the earthquake can be minimized to the maximum extent.

[0003] For example, in a rock formation simulation device for rock and soil seismic wave observation experiment with authorization announcement number CN215495648U, it includes a simulation box, the bottom of the simulation box is installed on a base, the base is composed of a trapezoidal platform and a support plate, the inner wall of the bottom of the simulation box is slidably connected with a vibration plate, the bottom of the vibration plate is fixedly connected to a support spring on the support plate, a plurality of screw holes 1 are provided at the bottom of the vibration plate, a connecting plate below the vibration plate is threadedly connected to the screw hole 1 through screw holes 2 provided on its surface and a connecting plate, a vibration spring is fixedly connected to the bottom of the connecting plate, and an impact ball is fixedly connected to the bottom of the vibration spring, the impact ball and the vibration spring at the bottom of the simulation box are pulled together with a motor and a flywheel to make the impact ball rebound and hit the vibration plate after being pulled down, thereby simulating the occurrence of an earthquake, the position of the earthquake source can be changed by changing the position of the connecting plate, and the number of rotations of the motor can be adjusted to change the pull-down distance of the impact ball, thereby changing the earthquake intensity, so that the experimental data monitoring is more sufficient;

[0023] As a further improvement of the utility model, Figure 2 and Figure 3As shown, the first vibration mechanism includes a moving shell 12 slidably connected to a connecting frame 10, a first motor 13 is fixedly connected to the inner side of the moving shell 12, a half gear 14 is fixedly connected to the end of the main shaft of the first motor 13, a rack 15 is meshed at one end of the half gear 14, and the rack 15 is slidably connected to the connecting frame 10, a knocking plate 17 is fixedly connected to the top of the rack 15, a second spring 16 is provided on the outer side of the rack 15, and the two ends of the second spring 16 are respectively fixedly connected to the knocking plate 17 and the moving shell 12, and the knocking plate 17 can knock on the vibration plate 7 under the cooperation of the rack 15 and the half gear 14, so as to simulate the influence of the longitudinal waves in the earthquake on the rock and soil stratum structure.
