Abstract
The utility model discloses a shallow exploration knocker used in the field of geological exploration. The shallow exploration knocker comprises wave detection, an iron hammer and an iron disc. The wave detector is connected with the wave detector and used for receiving the seismic waves; the iron hammer and the iron disc are used as seismic sources; the iron hammer is used as the positive pole of a trigger and connected with an oscilloscope; and the iron disc is used as the negative pole of the trigger and connected with the oscilloscope. The seismic sources are obtained by hammering the iron disc by the iron hammer, therefore, the exploration safety is improved, and the exploration cost is reduced. The shallow exploration knocker can be used for shallow geological exploration.
Description
Technical field
The utility model relates to a kind of exploration instrument for geology, particularly a kind of shallow layer exploration knocker.
Background technology
Method of seismic prospecting is widely used in the generaI investigation and exploration in oil, rock gas, coalfield; Shallow seismic exploration produces elastic wave through artificial excitation's vibrations; Elastic wave is propagated in underground medium; Utilize instrument and meter to accept the response signal that medium is stimulated and shakes, through physical property and the constructional aspect that underground medium is understood in the analysis and the explanation of signal.
In the prior art, generally carry out seismic prospecting through two kinds of methods, one of which, the method that adopts well borehole blasting ground to accept, this kind method can be guaranteed the accuracy of data, this method is wide shipping usefulness in the plains region, makes in the mountain area that cost is higher in this way; Its two, adopt the method for accepting in the ground blasting well, accept to replace well borehole blasting ground to accept in the ground blasting well, its cost is accepted low than well borehole blasting ground, but accepts to exist potential safety hazard in the ground blasting well; Above-mentioned two kinds of receiving methods all adopt the wave detector that links together with oscillograph to carry out the acceptance of reflection wave.
The utility model content
The purpose of the utility model provides a kind of shallow layer exploration knocker, has improved the security performance of exploration, and has reduced prospecting prime cost.
The purpose of the utility model is achieved in that a kind of shallow layer exploration knocker; Comprise the wave detector that carries out seismic event acceptance that links together with oscillograph; Also comprise iron hammer and discus as focus; Said iron hammer is connected on the oscillograph as the positive pole of trigger, and said discus is connected on the oscillograph as the negative pole of trigger.
During the utility model work, discus is placed on the ground, when iron hammer knocks discus; Iron hammer as the trigger both positive and negative polarity contacts synchronizing signal of generation and triggering with discus respectively, and oscillograph is started, and the seismic event that produces when iron hammer knocks discus is propagated in underground medium; The wave detector that utilization is inserted in the stratum is accepted the response signal that medium is stimulated and shakes, and wave detector is transferred to oscillograph with the signal that receives again and shows, through physical property and the constructional aspect that underground medium is understood in the analysis and the explanation of waveform signal; Compared with prior art; The beneficial effect of the utility model is: the utility model as focus, improved the security performance of exploration, and the cost of iron hammer and discus is lower through iron hammer hammering discus; Also reduce the cost of exploration, thereby improved income.The utility model can be used in the shallow layer exploration.
As the improvement of the utility model, said discus comprises big discus and the little discus that welds together.Avoided single discus under the effect of hammer force, wedging ground enables volume production and gives birth to decay, increases a big discus on little discus stratum and forms an energy-gathering ring, makes energy be able to down pass.
As the further improvement of the utility model, the diameter of said little discus is 0.618 times of big discus diameter.Guaranteed that further the energy that knocks gets following biography, avoided decay, thereby improved the record looks.
Description of drawings
Fig. 1 is the utility model structural representation.
Wherein, 1 stratum, the big discus of 2a, the little discus of 2b, 3 iron hammers, 4 oscillographs, 5 wave detectors.
Embodiment
A kind of shallow layer exploration knocker as shown in Figure 1; Comprise the wave detector 5 that carries out seismic event acceptance that links together with oscillograph 4; Also comprise iron hammer 3 and discus as focus, said iron hammer 3 is connected on the oscillograph 4 as the positive pole of trigger, and said discus is connected on the oscillograph 4 as the negative pole of trigger; Discus comprises big discus 2a and the little discus 2b that welds together, and little discus 2b diameter is 0.618 times of big discus 2a.
During the utility model work, discus is placed on the ground, simultaneously wave detector 5 is inserted in the stratum; Also can be provided with on the ground, when iron hammer 3 knocked discus, the iron hammer 3 as the trigger both positive and negative polarity contacted synchronizing signal of generation and triggering with discus respectively; Oscillograph 4 is started, and the seismic event that iron hammer 3 produces when knocking discus is propagated in underground medium, utilizes the wave detector 5 that is inserted in the stratum 1 to accept the response signal that medium is stimulated and shakes; Wave detector 5 is transferred to oscillograph 4 with the signal that receives again and shows, through to the analysis of waveform signal with explain physical property and the constructional aspect of understanding underground medium, and big discus 2a and little discus 2b that discus is arranged to weld together; And little discus 2b diameter is 0.618 times of big discus 2a, has avoided single discus under the effect of hammer force, wedging ground; Enable volume production and give birth to decay, thereby reflection wave is accepted in inconvenience, detect effect thereby reduce; The diameter ratio of the golden section of employing 0.618, maximization has guaranteed the transfer efficiency of seismic event.
The utility model is not limited to the foregoing description; As oscillographic both positive and negative polarity is put upside down; On the basis of the disclosed technical scheme of the utility model; Those skilled in the art does not need performing creative labour just can make some replacements and distortion to some technical characterictics wherein according to disclosed technology contents, and these replacements and distortion are all in the protection domain of the utility model.
Claims (3)
1. shallow layer exploration knocker; Comprise the wave detector that carries out seismic event acceptance that links together with oscillograph; It is characterized in that; Also comprise iron hammer and discus as focus, said iron hammer is connected on the oscillograph as the positive pole of trigger, and said discus is connected on the oscillograph as the negative pole of trigger.
2. a kind of shallow layer exploration knocker according to claim 1 is characterized in that, said discus comprises big discus and the little discus that welds together.
