Therefore, the features limited by "first", "second" and the like can explicitly or implicitly include one or more of the features. In the description of the utility model, the meaning of "a plurality of" is two or more, unless otherwise specified.

[0027] In the description of the utility model, it needs to be explained that, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected, it can be mechanically connected, or it can be electrically connected, it can be directly connected, or it can be indirectly connected through an intermediate medium, it can be the communication between two elements. For ordinary skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific circumstances.

[0028] The utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0029] A seismic wave demonstration device, which can be schematically shown as Figures 1-4 In this embodiment, the seismic wave demonstration device comprises a bearing plate 1, a longitudinal wave demonstration unit and a transverse wave demonstration unit, wherein the bearing plate 1 is used to provide a mounting base for other components in the device, the longitudinal wave demonstration unit is used to demonstrate the longitudinal wave form and transmission process of the seismic wave, and the transverse wave demonstration unit is used to demonstrate the transverse wave form and transmission process of the seismic wave.

[0030] Specifically, as shown in Figure 1 and Figure 2 , the longitudinal wave demonstration unit comprises a first support seat 2, a second support seat 3, a driving assembly and a longitudinal wave demonstration spring 4. The first support seat 2 and the second support seat 3 are arranged in parallel on the bearing plate 1, forming a longitudinal wave demonstration area between the first support seat 2 and the second support seat 3, and a containing groove is provided on the side wall of the second support seat 3 close to the longitudinal wave demonstration area. The driving assembly is arranged inside the containing groove, and the longitudinal wave demonstration spring 4 is arranged inside the longitudinal wave demonstration area, and one end of the longitudinal wave demonstration spring 4 is connected with the first support seat 2, and the other end is connected with the driving assembly.

[0031] During the demonstration and explanation of P-waves in seismic waves, the drive component can input energy into one end of the P-wave demonstration spring 4. Because the P-wave demonstration spring 4 has elastic deformation capability, after the drive component inputs energy, the energy will diffuse along the axial direction of the P-wave demonstration spring 4. At this time, the audience can understand the vibration mode and transmission process of the P-wave by observing the dynamic changes of the P-wave demonstration spring 4.

[0032] Optionally, to achieve the assembly of the longitudinal wave demonstration spring 4, such as... Figure 3 As shown, both ends of the longitudinal wave demonstration spring 4 can be provided with a fixing plate 41, and a connecting rod 42 is provided at the end of each fixing plate 41 away from the longitudinal wave demonstration spring 4. The connecting rods 42 on both sides of the longitudinal wave demonstration spring 4 should be connected to the first support base 2 and the drive assembly respectively.

[0033] Furthermore, to facilitate control of the amplitude and frequency of the longitudinal wave, the driving assembly in this embodiment may include a driving cylinder 71 and a piston head 72. During assembly, the piston head 72 should be mounted on the telescopic rod of the driving cylinder 71, and the longitudinal wave demonstration spring 4 should be connected to the piston head 72. When energy is input to the longitudinal wave demonstration spring 4, the extension and retraction of the telescopic rod of the driving cylinder 71 drives the piston 72 to move, thereby compressing and stretching the longitudinal wave demonstration spring 4, causing it to deform. When it is necessary to demonstrate longitudinal waves with different amplitudes and frequencies, the operator can adjust the stroke and frequency of the driving cylinder 71 to make the longitudinal wave demonstration spring 4 exhibit different vibration amplitudes and frequencies.

[0034] As an optional implementation of this embodiment, to avoid the longitudinal wave demonstration spring 4 being affected and interfered with by the external environment, the longitudinal wave demonstration unit may also include a transparent protective tube 43 made of glass or acrylic material. During assembly, the transparent protective tube 43 should be sleeved on the outside of the longitudinal wave demonstration spring 4, and both ends of the transparent protective tube 43 should be connected to the first support base 2 and the second support base 3 respectively, thereby isolating the longitudinal wave demonstration spring 4 from the external environment and facilitating the audience to observe the operation of the longitudinal wave demonstration spring 4.

[0035] like Figure 1 As shown, the shear wave demonstration unit in this embodiment includes a shear wave belt 5 and two buffer seats 6. The two buffer seats 6 are arranged parallel to each other on the support plate 1, forming a shear wave demonstration area between them. The shear wave belt 5 is located inside the shear wave demonstration area, and both ends of the shear wave belt 5 are connected to the two buffer seats 6 respectively. Multiple shear wave swing rods 51 are also provided on the shear wave belt 5. The multiple shear wave swing rods 51 are evenly arranged along the length direction of the shear wave belt 5, and the length direction of any one of the shear wave swing rods 51 is perpendicular to the length direction of the shear wave belt 5.

[0036] In the demonstration of the transverse wave of the seismic wave, the staff can push the transverse wave swing rod 51 at one end of the transverse wave ribbon 5 to make the transverse wave ribbon 5 obtain energy input. At this time, the energy will spread along the length direction of the transverse wave ribbon 5, so that the multiple transverse wave swing rods 51 on the transverse wave ribbon 5 swing in turn to embody the vibration form and transmission process of the transverse wave, thereby facilitating the audience to intuitively understand the transverse wave of the seismic wave.

[0037] Optionally, in order to improve the action amplitude of the transverse wave swing rod 51, the transverse wave swing ball 52 should be arranged at both ends of any one transverse wave swing rod 51, so as to facilitate the audience to observe the movement process of the transverse wave swing rod 51.

[0038] In addition, in order to control the amplitude of the transverse wave, the transverse wave demonstration unit in the embodiment can further include at least one telescopic support frame 9. Specifically, the telescopic support frame 9 should be arranged between the two buffer seats 6, and one end of the telescopic support frame 9 is connected with the bearing plate 1 and the other end is in contact with the transverse wave ribbon 5. Before use, the staff can drive the telescopic support frame 9 to perform telescopic action, so as to adjust the tension of the transverse wave ribbon 5 by means of the telescopic support frame 9. When the tension in the transverse wave ribbon 5 is large, the resistance of the transverse wave swing rod 51 to swing will be large, so it can be used to demonstrate the transverse wave with small amplitude. Correspondingly, when the tension in the transverse wave ribbon 5 is small, the resistance of the transverse wave swing rod 51 to swing will be small, so it can be used to demonstrate the transverse wave with large amplitude.

[0039] Figure 4 The schematic view of the telescopic support frame 9 is shown in the figure. The telescopic support frame 9 can include a first support rod 91 and a second support rod 92. The first support rod 91 is provided with a positioning hole, and a positioning bolt 911 is arranged in the positioning hole. The second support rod 92 is provided with a guide long circular hole 921 for accommodating the positioning bolt 911, and the length direction of the guide long circular hole 921 is parallel to the length direction of the second support rod 92. When the telescopic support frame 9 needs to perform telescopic action, the staff can loosen the positioning bolt 911 so that the second support rod 92 can slide relative to the first support rod 91. When the length of the telescopic support frame 9 meets the use requirement, the staff can tighten the positioning bolt 911 to fix the relative position of the second support rod 92 and the first support rod 91.

[0040] As another optional embodiment of the embodiment, in order to further improve the demonstration effect, the device can further include a demonstration screen 8. As shown in the figure, Figure 1As shown, the side wall of the demonstration screen 8 should be provided with a connecting seat 81, and the connecting seat 81 is hinged with the second supporting seat 3 through a damping rotating shaft. Before the demonstration and explanation of the seismic wave is carried out, the staff can adjust the angle of the demonstration screen 8, so as to facilitate the audience to watch the demonstration screen 8. When the demonstration and explanation of the seismic wave is carried out, the staff can play the video materials related to the earthquake through the demonstration screen 8 synchronously, so that the audience can obtain a more stereoscopic and intuitive demonstration and explanation effect.

[0041] The effect of the above scheme is described as follows:

[0042] The embodiment provides a seismic wave demonstration device, which can intuitively demonstrate the longitudinal wave and the transverse wave of the seismic wave through the longitudinal wave demonstration unit and the transverse wave demonstration unit, and facilitates the audience to understand the vibration mode and the transmission process. Secondly, the device can control the vibration frequency and the amplitude of the longitudinal wave through the action frequency and the action stroke of the driving cylinder, and can adjust the tension of the transverse wave belt through the telescopic supporting frame, and then control the amplitude of the transverse wave, so as to meet various demonstration requirements. In addition, the device can also play the video materials related to the earthquake through the demonstration screen, so as to strengthen the demonstration and explanation effect of the device.

[0043] It should be additionally explained that the device should also be provided with a line for providing power supply and data transmission for the demonstration screen 8, and should be provided with a controller for controlling the driving cylinder 71 to act. Since the line connection structure of the demonstration screen 8 and the specific structure of the controller are prior art, thus, details are not described herein.

[0044] The above only describes the preferred embodiment of the utility model, and does not limit the utility model, and any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model should be included in the protection scope of the utility model.
