Abstract
The utility model relates to a demonstration device for longitudinal and transversal waves of an earthquake. The demonstration device is characterized in that a motor is connected with an eccentric rod; the eccentric rod drives a transversal wave lever and a longitudinal wave lever in the rotation of the motor; one end of the longitudinal wave lever is connected with a buffer spring, and the other end of the longitudinal wave lever is connected with a longitudinal wave spring; and one end of the transversal wave lever is connected with a buffer spring, and the other end of the transversal wave lever is connected with a transversal wave spring. Upper ends of the longitudinal wave spring and the transversal wave spring are respectively connected with a longitudinal puppet and a transversal puppet positioned in a surface module. The motor drives a mechanical mechanism to instantly and rapidly generate horizontal movement and vertical movement, and waveforms of a transversal wave and a longitudinal wave spreading upwardly on the springs are generated. After the transversal wave and the longitudinal wave arrive at the surface of land, the puppets in the surface module are driven to shake, thereby completing the demonstration process. The demonstration device can generate complete longitudinal waves and transversal waves in a simple and rapid manner, and the springs are utilized as carriers for connecting the puppets on the surface of land, so that the form and characteristics of complete waveforms can be seen clearly, and influences of earthquake waves on the surface of land can be observed visually.
Description
Technical field
The utility model relates to a kind of device of demonstrating vertical and horizontal seismic wave.
Background technology
Earthquake, is the extremely strong Sudden Natural Disasters of a kind of destructiveness, has sudden strong, crushing large, the feature such as secondary disaster is serious, social influence is large.Simulated earthquake can strengthen the understanding of people to earthquake effectively, adopts an effective measure in time and carries out shockproof and shock-absorbing.Common seismic event demonstration instrument, adopts mechanical drive mode at present, and manually control spring and bead move to demonstrate wave propagation.The general bead that adopts helical arrangement on a rotating cylinder, rotate rotating cylinder and simulate with bead, or the particle movement simulation wave propagation that adopts machinery to drive, but all directly perceived not and vivid, be difficult to find out the impact of seismic event on mankind's activity, also cannot show feature and the propagation characteristic of seismic event.
Summary of the invention
In order to solve the ago problem of the inadequate visual pattern of seismic wave demonstration instrument, seismic event demonstration instrument is improved.The utility model solves the technical scheme that its technical matters adopts: a kind of instrument of demonstrating vertical and horizontal seismic wave, comprising: direct current generator connects eccentric rod, eccentric rod and drives successively shear wave lever and compressional wave lever, compressional wave lever one end by buffer spring, to be connected that the buffering other end connects compressional wave spring, shear wave lever one end connects buffering other end connection shear wave spring by buffer spring.Compressional wave spring is connected respectively with shear wave spring upper end compressional wave image and the shear wave image that is arranged in terrain model.
The beneficial effects of the utility model are: with direct current generator, drive eccentric rod that the periodicity power of mass motion is provided, make spring obtain larger deformation, waveform is more complete, obvious, and can make the demo system can continuous operation.The utility model is used small-sized image to embody the impact that vertical and horizontal seismic wave causes earthquake region personnel, can allow visitor have more intuitive understanding to the impact of seismic wave differently.The utility model is skillfully constructed, simple in structure, easy for installation, saving space, low price, easily popularization.
