Abstract
The utility model discloses a simulation demonstrator of collapse earthquake, and aims at providing a collapse earthquake model which has a simple structure, can be automatically reset and used for repeatedly demonstrating. The simulation demonstrator is technically characterized in that the simulation demonstrator comprises a demonstration device and a driving device; the demonstration device comprises an operating console (16) and a ground sand table model (17) with collapse ground (18); the driving device is positioned below the collapse ground (18); and the driving device comprises a framework (12), a motor (1), a synchronizing wheel (2), a synchronous belt (14), a ball screw (4), a connecting plate (9), a sliding block connecting block (10) and a stainless steel shaft (11).
Description
Technical field
The utility model relates to a kind of depression earthquake analog demonstrator.
Background technology
Earthquake is one of human irresistible paroxysmal spontaneous phenomenon, and earthquake can be divided into artificial earthquake and earthquake.Be artificial earthquake by what mankind's activity (as cut into a mountain, open a mine, explosion etc.) caused, just in addition be referred to as earthquake.Earthquake mainly can be divided into tectonic earthquake, volcanic earthquake, depression earthquake, bring out four big types of earthquakes by the origin cause of formation.Maximum, the destructive maximum earthquakes of frequency are tectonic earthquakes on the earth.
Depression earthquake is because underground water has dissolved the solubility rock, makes in the rock cavity to occur and enlarge gradually, or because underground mining has formed huge cavity, causes rock top and soil slide to subside and causes earthquake.Depression earthquake mainly occurs in ls or other karst rocks area, because underground karst cavity constantly enlarges, the avalanche of top, hole causes vibrations.The hole, ore deposit subsides or extensive landslide, landslide etc. also can cause this type earthquake to take place.This type earthquake accounts for about 3% of earthquake sum, and earthquake magnitude is all very little.Mining area depression earthquake maximum can reach about 5 grades, and 4 grades depression earthquake once took place in China.Though the focus of depression earthquake is shallow, still can cause more serious destruction to the mine upper and lower, and threaten miner's life security, should come into the picture.
Summary of the invention
The purpose of the utility model is the origin cause of formation to depression earthquake, and a kind of depression earthquake analog demonstrator is provided, and the destruction when taking place through reproducing depression earthquake makes spectators better be familiar with the understanding earthquake, strengthens people's consciousness of preventing and reducing natural disasters.
To achieve these goals, the utility model is achieved through following technical scheme: the depression earthquake simulator, comprise apparatus for demonstrating and drive unit, apparatus for demonstrating by operating console with have the ground sand table model of subsideing ground and form; Drive unit is positioned at subsides below the ground, and it is characterized in that: said drive unit comprises: framework, motor, synchronizing wheel, synchronous band, ball-screw, web joint, slide block contiguous block, stainless steel shaft, wherein:
Motor is installed on the bracing frame of framework, and the output axle head of said motor is installed synchronizing wheel and is connected with expansion tightening wheel through being with synchronously; One end of ball-screw is connected with synchronizing wheel, and the other end is connected with web joint; The slide block contiguous block is installed at the two ends of said web joint respectively, with the framework both sides of said slide block contiguous block correspondence position stainless steel shaft is being installed.
Adopt technique scheme, the fixed mount that ball-screw is made up of connecting link, linear bearing and fixed head is fixed, and said fixed mount is fixedly mounted on framework through ball-screw nut) on.
Adopt technique scheme, sand table model top, ground is furnished with projector.
In sum; The utility model is owing to adopted on ground sand table model top to be furnished with projector; Can want the content understood according to spectators; Play corresponding simulated scenario, when the simulation sand table is demonstrated earthquake precursors phenomenon, earthquake synchronously and is taken place tomography up and down and subsideing of producing of the left and right sides changing of the relative positions and earthquake, also demonstrated the relation between focus, earthquake magnitude and the earthquake intensity of earthquake simultaneously.
Description of drawings
Fig. 1 is a depression earthquake simulator front view;
Fig. 2 is the structural drawing of depression earthquake simulator drive unit;
Among the figure, 1 motor, 2 synchronizing wheels, 3 expansion tightening wheels, 4 ball-screws, 5 ball-screw nuts, 6 connecting links, 7 linear bearings, 8 fixed heads, 9 web joints, 10 slide block contiguous blocks, 11 stainless steel shafts, 12 frameworks, 13 fixed mounts, 14 are with synchronously, 15 bracing frames, 16 operating consoles, 17 ground sand table models, 18 are subside ground.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the utility model is done further to set forth:
The face of land on the push control desk 16 subsides pushbutton enable drive motor 1, drives synchronizing wheel 2 and rotates, and synchronizing wheel 2 is through expansion tightening wheel 3, be with 14 to drive ball screws 4 synchronously; Ball-screw 4 drives web joint 9 successively and moves up and down, and then promotes framework 12 elevating movements, has realized that the ground sand table model subsides with the face of land and collapse, simultaneity factor reset the face of land, back subside also automatically reset thereupon, demonstration repeatedly.Through regulating the frequency modulation of motor 1, can simulate the ground subsidence of the different focus depths, earthquake magnitude size simultaneously.
