At present, some popular science propaganda units such as the Science and Technology Museum have launched seismic wave demonstrators. When the seismic wave demonstrator is in use, the handle set on the seismic wave demonstrator is manually turned left and right. When the handle is turned, the spring on the seismic wave demonstrator is driven to shake, and the shaking spring drives the ground mold on the spring to shake. People can deepen their understanding of seismic waves by observing the shaking of the spring and the ground mold. However, in actual use, there are many visitors to some popular science propaganda units such as the Science and Technology Museum. When operating the seismic wave demonstrator, people's hands are directly in contact with the handle of the seismic wave demonstrator, especially children are prone to contact infection with viruses and bacteria, which is not conducive to the health of children. At the same time, it is inevitable that some people will use too much force when turning the handle of the seismic wave demonstrator back and forth, causing damage to the handle of the seismic wave demonstrator, which is not conducive to extending the service life of the seismic wave demonstrator.

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Example 1: Reference Figure 1-5 A seismic wave demonstration device includes a seismic wave demonstrator 1, a base 2 is fixed on the seismic wave demonstrator 1, a first cover body 3 is sleeved on the handle of the seismic wave demonstrator 1, a connecting rod 4 is fixed on the first cover body 3, a linear motor 5 is fixed on the connecting rod 4, the linear motor 5 is fixed on the seismic wave demonstrator 1, the linear motor 5 drives the first cover body 3 to move reciprocatingly through the connecting rod 4, the reciprocating first cover body 3 reciprocatingly moves the handle of the seismic wave demonstrator 1, and then starts the seismic wave demonstrator 1 to demonstrate shear waves, the linear motor 5 is electrically connected to a control mechanism, the control mechanism is fixed on the base 2, and the control mechanism is used to start and shut down the linear motor 5.

[0022] The control mechanism includes a second cover body 6, on which a plurality of springs 9 are fixed at equal intervals, and the plurality of springs 9 are all fixed on the base 2. The arrangement of the plurality of springs 9 allows the distance between the second cover body 6 and the base 2 to be adjusted. A touch switch 8 is fixed on the base 2 at the center formed by the plurality of springs 9, and the touch switch 8 wires are connected to the linear motor 5. A fixing column 7 is fixed on the second cover body 6 directly above the touch switch 8. When the second cover body 6 is pressed down, the fixing column 7 that descends with the second cover body 6 presses on the touch switch 8, and the linear motor 5 is turned on by the touch switch 8. When the pressure on the second cover body 6 is removed, the second cover body 6 drives the fixing column 7 to move away from the touch switch 8, and at this time, the linear motor 5 will be turned off.

[0023] Each spring 9 is provided with an insert column 16 and a cylinder 17, which are respectively fixed on the second cover body 6 and the base 2. The insert column 16 is inserted in the cylinder 17. The cooperation between the insert column 16 and the cylinder 17 ensures that when the distance between the second cover body 6 and the base 2 is adjusted, the second cover body 6 will not deviate and will only move up and down in a straight line.

[0024] When in use, by standing on the second cover body 6, the second cover body 6 drives the fixed column 8 to descend, and the descending fixed column 8 is used to squeeze the touch switch 8, and the linear motor 5 is started by the touch switch 8. The linear motor 5 can move the handle of the seismic wave demonstrator 1 back and forth through the connecting rod 4 and the first cover body 3, so that the seismic wave demonstrator 1 can complete the demonstration of seismic waves. In this process, people do not need to touch the handle of the seismic wave demonstrator 1 with their hands, which can avoid the infection of viruses and bacteria caused by contact, and can also protect the handle of the seismic wave demonstrator 1 to avoid the handle of the seismic wave demonstrator 1 from breaking due to improper operation, thereby extending the service life of the seismic wave demonstrator 1.

[0025] Embodiment 2: In embodiment 1, although people standing on the base 2 can directly see the fluctuation of the spring and the ground mold on the seismic wave demonstrator 1, the fluctuation mode of the handle of the seismic wave demonstrator 1 is blocked by the spring on the seismic wave demonstrator 1, which is not conducive to the people standing on the base 2 to watch the demonstration of the seismic wave demonstrator 1 from all directions, affecting the demonstration effect of the shear wave of the seismic wave demonstrator 1. Figure 1 , 2 , 3, 4 and 6, as another preferred embodiment of the utility model, is different from embodiment 1 in that a foot switch 10 is fixed on the second cover body 6, and a rotating mechanism is electrically connected to the foot switch 10, and the rotating mechanism is fixed on the seismic wave demonstrator 1 and the base 2. The rotating mechanism can drive the seismic wave demonstrator 1 to rotate, so that people can intuitively and comprehensively see the demonstration of seismic shear waves of the seismic wave demonstrator 1.

[0026] The rotating mechanism includes a motor 13, which is fixed on the base 2. A rotating shaft 12 is fixed on the output shaft of the motor 13, and the rotating shaft 12 is fixed on the seismic wave demonstrator 1. The motor 13 is electrically connected to the foot switch 10. The motor 13 is started by the foot switch 10. The motor 13 can drive the seismic wave demonstrator 1 to rotate 180 degrees through the rotating shaft 12, and a controller is connected to the motor 13. After the circuit between the foot switch 10 and the motor 13 is disconnected, the motor 13 will be reversed 180 degrees by the controller to restore the seismic wave demonstrator 1 to its original position.

[0027] A plurality of supporting legs 14 are fixed on the seismic wave demonstrator 1 around the rotating shaft 12, and a pulley 15 is fixed on each supporting leg 14, and the pulley 15 is in contact with the base 2. A third cover body 11 is fixed on the seismic wave demonstrator 1, and the rotating shaft 12 and the plurality of supporting legs 14 are all arranged inside the third cover body 11. When in use, after people stand on the second cover body 6 and see the transverse wave demonstrated by the seismic wave demonstrator 1, if they want to see how the handle of the seismic wave demonstrator 1 is moved without obstruction, they can step on the foot switch 10, and the seismic wave demonstrator 1 will rotate 180 degrees driven by the motor 13. Since the first cover body 3 is transparent, people can see the moving process of the handle of the seismic wave demonstrator 1 without obstruction. After the foot leaves the foot switch 10, the seismic wave demonstrator 1 will return to its original position, which is convenient for others to watch.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
